O bservers of the economy have clearly documented that U.S. aggregate output has become much less volatile since the early 1980s. The accompanying chart plots the annualized standard deviation of quarterly growth of real gross domestic product (GDP) using a 60quarter rolling window. The value corresponding to 1962:Q2 is the standard deviation of GDP growth between 1947:Q3 and 1962:Q2, for example. The downward movement in output volatility is particularly pronounced after 1984: The standard deviation of economic growth declined sharply from over 4 percent to about 2 percent in recent years. Economists have put forth three explanations why output growth may have become more stable in the past 20 years. One focuses on the conduct of monetary policy and the accompanying decline in inflation. Prior to the early 1980s, the Federal Reserve relied at times on recessions to rein in inflation. Since then, the Federal Reserve has been proactive in keeping inflation contained. Another explanation is that the U.S. economy simply has enjoyed good fortune in that there have been, for example, fewer tumultuous oil price shocks, which can cause volatility in economic activity. The third explanation suggests that improvements in inventory management are important for understanding the reduction in volatility. That is, while the durable goods sector has experienced a dramatic decline in output volatility in the past two decades, final sales of durable goods have seen only a moderate decline in volatility. Therefore, durable goods inventories—the difference between production and final sales—account for a substantial reduction in output variability in the durable goods sector and in the aggregate economy. Stock and Watson (2002) conduct a comprehensive analysis on this issue and provide some insights on the relative importance of the three hypotheses in explaining the decline in output volatility.1 Their results indicate that improved monetary policy could account for 20 to 30 percent of the volatility reduction and that smaller shocks probably account for most of the rest. However, they acknowledge that their conclusions are tentative and are open to further investigation. The fact that U.S. output growth is more stable now than it was two decades ago has important implications in interpreting economic data. For example, in the 1970s, changes in annualized GDP growth that seem large by today’s standards were, back then, within one standard deviation of the mean and thus policymakers could consider them noise. In contrast, a shock to output growth of a similar magnitude today would be cause for believing that the economy might be near a business cycle turning point and would be more likely to elicit a prompt response from monetary policymakers. Perhaps for this reason, Federal Reserve policymakers began cutting the federal funds rate aggressively in January 2001, based on a slowing economy that would not actually enter a recession until March 2001.
经济观察家已经清楚地证明,自20世纪80年代初以来,美国总产出的波动性已经大大降低。随附的图表使用60个季度的滚动窗口绘制了实际国内生产总值(GDP)季度增长的年化标准差。例如,1962:Q2对应的值是1947:Q3到1962:Q2之间GDP增长的标准差。产出波动率的下降趋势在1984年之后尤为明显:近年来,经济增长的标准偏差从4%以上急剧下降到2%左右。经济学家对产出增长为何在过去20年变得更加稳定提出了三种解释。其一是关注货币政策的实施以及随之而来的通货膨胀的下降。在20世纪80年代早期之前,美联储有时会依靠经济衰退来控制通胀。自那以后,美联储一直在积极控制通胀。另一种解释是,美国经济只是运气好,例如,油价波动较少,这可能导致经济活动的波动。第三种解释表明,库存管理的改进对于理解波动性的降低很重要。也就是说,虽然耐用品部门在过去二十年中经历了产出波动性的急剧下降,但耐用品最终销售的波动性仅略有下降。因此,耐用品库存——生产和最终销售之间的差额——在耐用品部门和总体经济中导致了产出变异性的大幅减少。Stock和Watson(2002)对这一问题进行了全面的分析,并对三种假设在解释产出波动率下降时的相对重要性提供了一些见解他们的研究结果表明,改善的货币政策可能占波动性降低的20%至30%,而较小的冲击可能占其余部分的大部分。然而,他们承认他们的结论是暂定的,有待进一步调查。美国目前的产出增长比20年前更加稳定,这一事实对解读经济数据具有重要意义。例如,在20世纪70年代,按今天的标准来看,年化GDP增长的变化似乎很大,但在当时,这些变化与平均值相差不到一个标准差,因此政策制定者可以将其视为噪音。相比之下,今天对产出增长的类似程度的冲击,将使人们有理由相信,经济可能正接近商业周期的转折点,并更有可能促使货币政策制定者迅速做出反应。也许正是出于这个原因,美联储的政策制定者在2001年1月开始大幅下调联邦基金利率,当时的预测是经济放缓,而且直到2001年3月才会真正进入衰退。

Foreign exchange rates are predictable 外汇汇率是可以预测的

Views expressed do not necessarily reflect official positions of the Federal Reserve System. Modern economic theory of foreign exchange rates stipulates that the Deutsche mark/U.S. dollar rate, for example, is equal to discounted future fundamentals—e.g., aggregate income, interest rates, and monetary aggregates—in both the United States and Germany. A substantial portion of the variation in these fundamental macroeconomic variables is predictable across time; therefore, fundamentals should provide important information about future movements in exchange rates. In an influential paper, Meese and Rogoff (1983), however, find that a simple random walk model, in which the forecasted value is the most recent realization, outperforms various forecasting models, including those using economic fundamentals as predictors.1 Meese and Rogoff’s result has inspired numerous empirical investigations of exchange rate predictability, and their conclusion has proven to be strikingly robust after 20 years of fresh data and intensive academic research. In light of seemingly compelling evidence, some recent authors argue that exchange rates are indeed unpredictable—possibly because some shocks have a permanent effect on economic fundamentals. In particular, if people discount the future very little relative to the present, then exchange rates could follow a process close to a random walk. Other economists, however, argue that exchange rates are predictable and that existing empirical studies suffer from various misspecifications. For example, some crucial fundamental determinants of exchange rates may have been omitted. Also, many macroeconomic variables are subject to periodic revisions; therefore, the current vintage data, which have been commonly used in the literature, do not contain the same information as that available to investors at the time of forecast. To address these issues, Guo and Savickas (2005) propose using financial variables, which are broad measures of business conditions and never revised, to predict exchange rates.2 Guo and Savickas find that a measure of U.S. aggregate idiosyncratic volatility (IV) is a strong predictor of the exchange rates of the U.S. dollar against major foreign currencies, especially at relatively long horizons. An idiosyncratic shock to a stock is the part of the stock return that is not explained by asset pricing models. To measure IV, Guo and Savickas first estimate idiosyncratic shocks to all (U.S.) common stocks included in the CRSP (Center for Research in Security Prices) database; they then aggregate the realized variance of idiosyncratic shocks across stocks using the share of market capitalization as the weight. The accompanying chart plots IV from the last quarter of each year (in natural logarithms, solid line) along with one-yearahead changes (December 31 to December 31 of the following year, dashed line) in the Deutsche mark/U.S. dollar rate over the period 1973 to 1998 and the Euro/U.S. dollar rate over the
本文所表达的观点不一定反映联邦储备系统的官方立场。现代外汇汇率经济理论规定,德国马克兑美元汇率为1例如,美元汇率等于贴现后的未来基本面。包括美国和德国的总收入、利率和货币总量。这些基本宏观经济变量的很大一部分变化是可以预测的;因此,基本面应该提供有关汇率未来走势的重要信息。然而,在一篇有影响力的论文中,Meese和Rogoff(1983)发现,一个简单的随机游走模型,其中预测值是最近实现的,优于各种预测模型,包括那些使用经济基本面作为预测指标的模型米斯和罗格夫的结果激发了大量关于汇率可预测性的实证研究,经过20年的新数据和密集的学术研究,他们的结论已被证明是非常有力的。鉴于看似令人信服的证据,最近一些作者认为,汇率确实是不可预测的——可能是因为一些冲击对经济基本面有永久性的影响。特别是,如果人们对未来的贴现相对于现在很少,那么汇率可能会遵循一个接近随机游走的过程。然而,其他经济学家认为,汇率是可预测的,现有的实证研究存在各种各样的错误规范。例如,一些关键的汇率基本决定因素可能被忽略了。此外,许多宏观经济变量需要定期修订;因此,文献中常用的当前年份数据并不包含与预测时投资者可获得的信息相同的信息。为了解决这些问题,Guo和Savickas(2005)提出使用金融变量来预测汇率,金融变量是商业状况的广泛衡量标准,从未修改过Guo和Savickas发现,衡量美国总体特殊波动率(IV)是美元兑主要外币汇率的有力预测指标,尤其是在相对较长的视野内。股票的特殊冲击是股票收益中不能用资产定价模型解释的部分。为了测量IV, Guo和Savickas首先估计了包含在CRSP(证券价格研究中心)数据库中的所有(美国)普通股的特殊冲击;然后,他们以市值占比为权重,将不同股票的特质冲击的实现方差汇总起来。随附的图表显示了每年最后一个季度的德国马克/美元汇率(实线为自然对数)以及一年前的变化(12月31日至次年12月31日,虚线)1973年至1998年期间的美元汇率和欧元兑美元汇率1999至2003年期间的美元汇率。图表显示,IV与未来一年美元价格的变化之间存在很强的正相关关系。例如,在最近的美元贬值之前,2001年美元汇率曾急剧下跌。总体而言,IV占德国马克/美元汇率变动的30%以上;IV在样本外预测方面也优于随机漫步模型。IV的预测能力符合经济学理论。特别是,许多早期作者认为,IV是冲击在不同部门之间分散的代表;高水平的分散会导致成本高昂的部门资源重新配置,从而减少产出和就业。事实上,郭和萨维卡斯表明,IV是GDP增长、固定私人企业投资和失业率的有力预测指标。此外,他们发现使用德国股票价格数据构建的总IV的度量也与德国马克的未来美元价格呈正相关。因此,尽管我们不能完全排除数据挖掘的可能性,但IV的预测能力似乎为经济基本面是外汇汇率的重要决定因素这一猜想提供了支持。回族郭

Financial aid and college choice 经济援助和大学选择
Pub Date : 1900-01-01 DOI: 10.20955/ES.2003.20

E ach year thousands of high school seniors make the important decision of where to go to college. With tuition at many schools rising faster than the rate of inflation, financing a college education is becoming increasingly challenging. (In fact, in the United States, the growth rate of college costs since 1990 has been, on average, nearly 3 percent higher than the overall inflation rate.) Offers of financial aid—a complex menu of grants, loans, and work-study—vary by school. Indeed, some students may consider a school’s academic attributes and their projected influence on the student’s lifetime earning potential as less important than the school’s financial aid package. Thus, the way students weight financial aid offers can have a substantial impact on their choice of college. Working with counselors from 510 U.S. high schools, economists Christopher Avery and Caroline Hoxby1 surveyed high-aptitude high school seniors (students likely to gain admission and merit scholarships from selective colleges) to study how students assess financial aid pack ages. In particular, they sought to determine how financial aid characteristics affect the probability that the student will choose a particular school, taking into account individual attributes: SAT score, GPA, legacy status, etc. Avery and Hoxby assert at the outset that there are distinguishing characteristics across financial aid packages that do not necessarily add value. Nevertheless, they find that approxi mately 30 percent of the students in their sample responded strongly to what are arguably trivial distinctions between financial aid packages. The first distinguishing characteristic is whether or not a grant is called a “scholarship.” Clearly, the amount of the grant, not its name, should be what matters. (In fact, the authors note that the amount of a grant is actually negatively correlated to it being designated as a “scholarship.”) Nevertheless, Avery and Hoxby find that students are very responsive to this distinction when deciding which college to attend. Students may consider a named scholarship to be more impressive than an unnamed grant when listed on resumes or job applications—perhaps because scholarship connotes merit-based aid and grant connotes need-based aid. The second characteristic Avery and Hoxby consider is whether or not the grant is front-loaded, meaning the student receives more aid in his or her freshman year than in later years. An example would be a grant that gives $10,000 the first year and $2,000 each of the subsequent three years as opposed to a grant that gives $4,000 each of the four years. Avery and Hoxby find strong student response to front-loading. Potential reasons for students to prefer front-loading are clear: Front-loading better allows students to consider the possibility of transferring to a different school after the first year or two; it gives parents more time to save money toward the total cost of college; and it gives parents the opportunity to ea
每年都有成千上万的高中毕业生做出去哪里上大学的重要决定。随着许多学校学费的上涨速度超过通货膨胀率,资助大学教育变得越来越具有挑战性。(事实上,在美国,自1990年以来,大学学费的增长率平均比整体通胀率高出近3%。)提供的经济援助——包括助学金、贷款和勤工俭学的复杂菜单——因学校而异。事实上,一些学生可能认为学校的学术属性及其对学生一生收入潜力的预计影响不如学校的经济援助计划重要。因此,学生衡量经济援助的方式会对他们的大学选择产生重大影响。经济学家克里斯托弗·艾弗里(Christopher Avery)和卡罗琳·霍克斯比(Caroline Hoxby1)与来自510所美国高中的辅导员合作,调查了高天赋的高中毕业生(可能获得名牌大学的录取和奖学金的学生),以研究学生如何评估经济援助计划。特别是,他们试图确定经济援助特征如何影响学生选择特定学校的可能性,同时考虑到个人属性:SAT分数,GPA,遗产状态等。艾弗里和霍克斯比在一开始就断言,在经济援助计划中有一些明显的特征,这些特征不一定会增加价值。然而,他们发现,在他们的样本中,大约有30%的学生对经济援助方案之间微不足道的区别反应强烈。第一个显著特征是补助金是否被称为“奖学金”。显然,重要的应该是赠款的数额,而不是名称。(事实上,作者指出,助学金的数额实际上与被指定为“奖学金”负相关。)然而,艾弗里和霍克斯比发现,在决定上哪所大学时,学生们对这种区别非常敏感。学生们可能会认为,在简历或工作申请中列出的有名字的奖学金比没有名字的奖学金更令人印象深刻——也许是因为奖学金意味着基于成绩的资助,而助学金意味着基于需求的资助。艾弗里和霍克斯比考虑的第二个特征是助学金是否提前发放,这意味着学生在大一获得的资助比以后的年份要多。举个例子,一项赠款第一年提供10,000美元,随后三年每年提供2,000美元,而另一项赠款四年每年提供4,000美元。艾弗里和霍克斯比发现,学生对“前置”的反应非常强烈。学生喜欢提前入学的潜在原因很明显:提前入学可以让学生更好地考虑在一到两年后转到另一所学校的可能性;这让父母有更多的时间为大学的总费用存钱;它还让父母有机会在支付大学学费之前,从储蓄中赚取利息。这些因素是否可以解释Avery和Hoxby所述的对前置加载的强烈反应,这是一个有争议的观点,因为很难对许多这些考虑因素赋予特定的价值。有人可能会问,学生对这两个方面的经济援助的敏感性是否取决于家庭背景,比如父母的收入和父母上的大学。艾弗里和霍克斯比提出了一些证据。他们发现,除了那些父母收入高或父母上过名牌大学的学生外,指定为奖学金的助学金对各个收入阶层的学生都有明显的吸引力。有趣的是,他们发现学生对提前入学的反应既不取决于家庭收入,也不取决于父母所上大学的选择性。在评估大学提供的经济援助激励时,学生和他们的家庭必须确定他们在竞争经济援助方案之间存在的细微差别中给予多少重视。经验证据表明,学生对经济援助因素的主观反应难以量化。有了对学生如何应对各种经济援助特征的更好认识,经济学家、教育工作者和政策制定者就能更好地理解大学选择的过程。

Index funds: hedgers or speculators? 指数基金:对冲者还是投机者?
Pub Date : 1900-01-01 DOI: 10.20955/ES.2008.17

Views expressed do not necessarily reflect official positions of the Federal Reserve System. The commodity futures market has changed dramatically over the past five years. The Goldman Sachs Commodity Index (GSCI) rose from 235 at the end of December 2002 to 787 on the last day of May 2008—an average annual commodity price inflation rate of 25 percent. The price of agricultural commodities rose about 15 percent, and energy prices soared almost twice as fast—at 29 percent. Futures market participants normally include commercial hedgers and speculators. Commercial hedgers are firms that produce the commodity or use it in producing goods and services. For example, wheat farmers sell wheat ahead of the harvest to hedge against a falling price at harvest time. On the other side of the market, the bread and pasta producers buy wheat in advance to hedge against the risk of rising prices in coming months (and years). Speculators bring liquidity to the market and are generally believed to make the market more efficient in discovering the equilibrium price. One big change in this market is the growth of index funds that invest in long positions. In 2002, only a small percentage of the long positions were held by such funds. Over the past five years, however, the index funds’ long positions have grown. They now represent a significant share of the investment in commodity futures. The rise of index funds has been accompanied by a rapid rise in the use of derivatives based on commodity price indices. Note, however, that not all of these investors are speculators. Although it is true that they are not hedging risk in the commodity markets, many large investors, including the employee pension funds for the federal government and the state of California, are using the commodity futures index funds to hedge risk in the stock and bond markets. Why the rapid growth in the use of commodity futures to hedge risk in the stock and bond markets? Readers seeking to understand this change are referred to a recent research paper by Gary Gorton and Geert Rouwenhorst in which they develop a data set on commodity futures prices that spans the period from July 1959 to December 2003.1 They analyze the return an investor would have earned on a long position in an equally weighted portfolio of investments in a broad set of commodity futures. They show that such an investment displays the riskreturn characteristics of a similar investment in equities. The most interesting fact they uncover, however, is that the return to commodity futures was negatively correlated with returns in both stocks and bonds. The commodity future returns are positively correlated with inflation, unexpected inflation, and changes in expected inflation. In other words, an investment in commodity futures would have been an effective hedge against the business cycle and inflation risk that had been thought difficult, if not impossible, to hedge. Of course, the history of returns likely would be different if
本文所表达的观点不一定反映联邦储备系统的官方立场。商品期货市场在过去五年中发生了巨大变化。高盛商品指数(GSCI)从2002年12月底的235上升到2008年5月最后一天的787——商品价格年平均通胀率为25%。农产品价格上涨了约15%,能源价格飙升了29%,几乎是前者的两倍。期货市场参与者通常包括商业套期保值者和投机者。商业套期保值者是生产或使用该商品生产商品和服务的公司。例如,麦农在收获季节前出售小麦,以对冲收获季节价格下跌的风险。在市场的另一边,面包和面食生产商提前购买小麦,以对冲未来几个月(甚至几年)价格上涨的风险。投机者给市场带来流动性,通常被认为使市场更有效地发现均衡价格。这个市场的一个重大变化是投资于多头头寸的指数基金的增长。2002年,此类基金持有的多头头寸只占很小比例。然而,在过去5年里,指数基金的多头头寸有所增加。它们现在在大宗商品期货投资中占据了相当大的份额。随着指数基金的兴起,基于大宗商品价格指数的衍生品的使用也迅速增加。但请注意,并非所有这些投资者都是投机者。虽然它们确实没有对冲商品市场的风险,但许多大型投资者,包括联邦政府和加利福尼亚州的雇员养老基金,正在使用商品期货指数基金来对冲股票和债券市场的风险。为什么在股票和债券市场中,利用商品期货对冲风险的行为迅速增长?想要了解这种变化的读者可以参考Gary Gorton和Geert Rouwenhorst最近发表的一篇研究论文,他们在论文中建立了一个从1959年7月到2003年12月的商品期货价格数据集。他们分析了投资者在一系列广泛的商品期货的同等权重投资组合中持有多头头寸所能获得的回报。他们表明,这种投资显示了类似的股票投资的风险回报特征。然而,他们发现的最有趣的事实是,大宗商品期货的回报与股票和债券的回报都呈负相关。商品的未来收益与通货膨胀、非预期通货膨胀和预期通货膨胀的变化呈正相关。换句话说,对商品期货的投资可以有效地对冲商业周期和通胀风险,而这些风险即使不是不可能对冲,也是很难对冲的。当然,如果大型投资者在过去47年里真的以这种方式利用大宗商品市场,那么回报率的历史可能会有所不同。近期大宗商品期货价格的上涨伴随着波动性的大幅上升,这提高了维持保证金账户的成本。来自第八联邦储备区的轶事证据表明,维持保证金账户的成本上升导致棉花和谷物市场上的商业对冲减少——至少对较小的市场参与者来说是这样。这一发展很有意思,因为商品期货市场现在不仅要对冲商品生产者和消费者面临的风险,还要对冲规模大得多的股票和债券市场的风险。这是一个未知的领域。看看大宗商品行业是否足够大,能够有效地确保所有这些风险,将是一件有趣的事情。

The commodity futures market has changed dramatically over the past five years. The Goldman Sachs Commodity Index (GSCI) rose from 235 at the end of December 2002 to 787 on the last day of May 2008—an average annual commodity price inflation rate of 25 percent. The price of agricultural commodities rose about 15 percent, and energy prices soared almost twice as fast—at 29 percent. Futures market participants normally include commercial hedgers and speculators. Commercial hedgers are firms that produce the commodity or use it in producing goods and services. For example, wheat farmers sell wheat ahead of the harvest to hedge against a falling price at harvest time. On the other side of the market, the bread and pasta producers buy wheat in advance to hedge against the risk of rising prices in coming months (and years). Speculators bring liquidity to the market and are generally believed to make the market more efficient in discovering the equilibrium price. One big change in this market is the growth of index funds that invest in long positions. In 2002, only a small percentage of the long positions were held by such funds. Over the past five years, however, the index funds’ long positions have grown. They now represent a significant share of the investment in commodity futures. The rise of index funds has been accompanied by a rapid rise in the use of derivatives based on commodity price indices. Note, however, that not all of these investors are speculators. Although it is true that they are not hedging risk in the commodity markets, many large investors, including the employee pension funds for the federal government and the state of California, are using the commodity futures index funds to hedge risk in the stock and bond markets. Why the rapid growth in the use of commodity futures to hedge risk in the stock and bond markets? Readers seeking to understand this change are referred to a recent research paper by Gary Gorton and Geert Rouwenhorst in which they develop a data set on commodity futures prices that spans the period from July 1959 to December 2003.1 They analyze the return an investor would have earned on a long position in an equally weighted portfolio of investments in a broad set of commodity futures. They show that such an investment displays the riskreturn characteristics of a similar investment in equities. The most interesting fact they uncover, however, is that the return to commodity futures was negatively correlated with returns in both stocks and bonds. The commodity future returns are positively correlated with inflation, unexpected inflation, and changes in expected inflation. In other words, an investment in commodity futures would have been an effective hedge against the business cycle and inflation risk that had been thought difficult, if not impossible, to hedge.

U.S. exporters: a rare breed 美国出口商:稀有品种

Views expressed do not necessarily reflect official positions of the Federal Reserve System. U.S. firms rarely engage in international trade. In 2000, for example, there were 5.5 million firms in the United States; of these only about 4 percent were exporters. And the top 10 percent of these exporters accounted for 96 percent of total U.S. exports. Not surprisingly, goods-producing firms account for the majority of exports (as measured by value). The table shows the distribution of exporting firms among 10 manufacturing industries ranked by their share of total manufacturing employment in 2002. Most manufacturing industries have some firms that export, but the share of those firms in each industry is relatively small, varying between 12 and 38 percent for the larger industries and between 12 and 25 percent for the smaller industries. Furthermore, across all industries, on average, a firm’s foreign shipments represent only a small proportion (never exceeding 21 percent) of total shipments. In manufacturing as a whole in 2002, only 18 percent of firms were exporters and only about 14 percent of total firm shipments were exports. Not only are exporting firms rare, they also stand out in several ways: Studies show that exporting firms are more productive in terms of value-added per worker and total factor productivity and that they ship a higher volume of products. They use more skilled workers, capital, and sophisticated technology than non-exporting firms. They also pay higher wages and are more innovative. (These differences persist even after accounting for firm size and industry type.) On the surface, exporting seems beneficial. So why don’t more firms export? One important distinction may offer a clue: Although the productivity level of exporting firms is higher than that of non-exporting firms, their productivity growth is not—which suggests that high productivity is a requirement for and not a consequence of engaging in international trade. High entry costs for exporting may be a barrier to all but the most efficient firms. At the same time, economists have also found that once firms begin exporting they experience faster growth than non-exporting firms in both employment and output (in both foreign and domestic shipments).1 Andrew Bernard and J. Bradford Jensen, along with coauthors, argue that the higher initial productivity of exporters, combined with higher output and employment growth after entry, suggests an important role for trade liberalization (a reduction of trade barriers) in improving the aggregate productivity of the economy.2 The reason is that a reduction in trade barriers would improve the profits of existing exporting firms and would reduce the initial productivity level necessary for additional firms to enter the export market. This additional entry would, in turn, generate an increased demand for labor and therefore higher wages. Low-productivity non-exporting firms would be forced to exit the industry, and both capital an
本文所表达的观点不一定反映联邦储备系统的官方立场。美国公司很少从事国际贸易。例如,在2000年,美国有550万家公司;其中只有4%是出口商。其中前10%的出口商占美国出口总额的96%。毫不奇怪,商品生产企业占出口的大部分(以价值衡量)。下表显示了2002年出口企业在制造业就业总量中所占份额排名的10个制造业中的分布情况。大多数制造业都有一些出口公司,但这些公司在每个行业中的份额相对较小,较大的行业在12%到38%之间,较小的行业在12%到25%之间。此外,在所有行业中,一家公司的海外发货量平均只占总发货量的一小部分(从未超过21%)。在2002年整个制造业中,只有18%的公司是出口商,只有14%的公司总出货量是出口。出口公司不仅罕见,而且在几个方面也很突出:研究表明,出口公司在每个工人的增加值和全要素生产率方面生产率更高,而且它们的产品出货量更高。它们比非出口企业使用更多的熟练工人、资本和尖端技术。他们还支付更高的工资,更有创新精神。(即使在考虑了公司规模和行业类型之后,这些差异仍然存在。)从表面上看,出口似乎是有益的。那么,为什么没有更多的公司出口呢?一个重要的区别可能会提供一个线索:尽管出口企业的生产率水平高于非出口企业,但它们的生产率增长不是——这表明高生产率是从事国际贸易的必要条件,而不是结果。除了效率最高的公司外,出口的高进入成本可能是所有公司的障碍。与此同时,经济学家也发现,一旦企业开始出口,它们在就业和产出(国外和国内出货量)方面的增长速度都要快于非出口企业安德鲁·伯纳德(Andrew Bernard)和j·布拉德福德·詹森(J. Bradford Jensen)及其合著者认为,出口商较高的初始生产率,加上进入后更高的产出和就业增长,表明贸易自由化(减少贸易壁垒)在提高经济的总生产率方面发挥了重要作用其原因是,减少贸易壁垒将提高现有出口企业的利润,并将降低更多企业进入出口市场所必需的初始生产率水平。这种额外的进入反过来会增加对劳动力的需求,从而提高工资。低生产率的非出口企业将被迫退出该产业,资本和劳动力要素将从效率较低的非出口企业重新配置到效率较高的出口企业。这将提高该行业的平均生产率。由于要素的再分配既发生在行业内部,也发生在行业之间,这将转化为整个经济的生产率提高。

Can Social Security survive the baby boomers 社会保障能在婴儿潮一代幸存下来吗
Pub Date : 1900-01-01 DOI: 10.20955/ES.2007.22

In 2010, the first of the Baby Boom generation will reach age 65. Many will choose to begin what they hope will be a long and financially secure retirement funded in part by Social Security. Social Security, however, has a looming fiscal problem. Social Security payments to current recipients are funded mainly by taxes levied on current workers. As more and more baby boomers retire, the number of persons receiving Social Security benefits will increase rapidly relative to the number of persons paying taxes to fund those benefits. Accord ing to the Trustees of the Social Security and Medicare Trust Funds, by 2017 Social Security benefit payments will exceed payroll tax revenues and by 2041 all trust fund assets likely will be exhausted.1 The Social Security System’s revenue shortfall mainly reflects a rising elderly dependency ratio: that is, the number of elderly persons (65+ years) relative to the number of working-age persons (20 to 64 years). As shown in the chart, in 1950 there were some 14 persons age 65 and older for every 100 persons between the ages of 20 and 64. By 2000, there were 20; and, as more of the baby boom generation reaches age 65, the ratio will rise to 35 by 2030. Although the coming stampede of baby boomers will cause the dependency ratio to increase sharply after 2010, rising adult life expectancy has been a major reason why the dependency ratio has risen and will continue to rise. The life expectancy of the typical 65year-old man has risen over the years: In 1940, he could expect to live another 12.7 years; by 2005, he could expect to live another 17.1 years; and demographers expect that, by 2030, he could expect to live another 18.7 years. Although the age at which persons are eligible for full Social Security benefits—long fixed at 65—will gradually rise to 67 by 2025, this won’t prevent System revenues from falling short of payments. Declining fertility has also contributed to this rising dependency ratio. In 1950, the U.S. fertility rate was 3.0, meaning the average woman had three children in her lifetime. By 2002, the fertility rate had fallen to 2.0. This decline implies that fewer young persons will enter the labor force to support the growing elderly population. Clearly, the looming Social Security funding crisis largely reflects changing U.S. demographics. The aging baby boom generation, increased adult life expectancy, and declining fertility will rapidly increase the number of retired persons drawing benefits relative to persons paying taxes to fund those benefits. Possible solutions to the problem include policies to (i) slow the growth in the number of retired persons per worker, perhaps by larger and more rapid increases in the age at which persons become eligible for benefits; (ii) otherwise reduce promised benefits; (iii) encourage more immigration of young workers; and/or (iv) substantially raise taxes on current workers. A more radical proposal would replace all or part of the existing system with a syst
2010年,第一代婴儿潮一代将年满65岁。许多人将选择开始他们希望的长期和经济上有保障的退休生活,部分资金来自社会保障。然而,社会保障面临着迫在眉睫的财政问题。目前领取者的社会保障金主要来自对当前工人征收的税收。随着越来越多的婴儿潮一代退休,相对于为这些福利纳税的人数,领取社会保障福利的人数将迅速增加。根据社会保障和医疗保险信托基金的受托人的说法,到2017年,社会保障福利支付将超过工资税收入,到2041年,所有信托基金资产可能会耗尽社会保障制度的收入不足主要反映了老年人抚养比率的上升:即老年人(65岁以上)与工作年龄人口(20至64岁)的比例。如图所示,1950年,每100名20岁至64岁的人中就有14名65岁及以上的人。到2000年,有20个;随着越来越多的婴儿潮一代达到65岁,到2030年,这一比例将升至35岁。尽管即将到来的婴儿潮一代将导致抚养比在2010年后急剧上升,但成年人预期寿命的延长一直是抚养比上升并将继续上升的主要原因。65岁男性的预期寿命多年来一直在上升:在1940年,他预计可以再活12.7年;到2005年,他有望再活17.1年;人口统计学家预计,到2030年,他预计可以再活18.7年。尽管人们有资格享受全部社会保障福利的年龄——长期固定为65岁——到2025年将逐渐提高到67岁,但这并不能阻止系统收入不足以支付。生育率下降也导致抚养比率上升。1950年,美国的生育率是3.0,这意味着平均每个妇女一生中有三个孩子。到2002年,生育率下降到2.0。这种下降意味着更少的年轻人将进入劳动力市场来支持不断增长的老年人口。显然,迫在眉睫的社会保障资金危机在很大程度上反映了美国人口结构的变化。婴儿潮一代的老龄化、成年人预期寿命的延长和生育率的下降将迅速增加领取福利的退休人员的数量,相对于为这些福利提供资金的纳税人员。解决这一问题的可能办法包括以下政策:(1)减缓每名工人的退休人数增长速度,方法可能是更大幅度、更迅速地提高领取福利的年龄;(二)以其他方式减少承诺的利益;(三)鼓励更多年轻工人移民;和/或(iv)大幅提高现有工人的税收。一个更为激进的提议是,用私人退休账户体系取代全部或部分现有体系。不幸的是,无论采取何种途径,解决资金危机都不可能不付出代价。

State budget crises: cause and effect 国家预算危机:因果关系
Pub Date : 1900-01-01 DOI: 10.20955/ES.2003.27
T. Garrett
S tate tax revenue grew markedly during the 1990s as a result of rapid economic growth. Burgeoning tax revenues, the resulting budget surpluses, and rosy revenue forecasts prompted almost every state to enact large permanent tax cuts. Ten states enacted cuts of between 1 and 3 percent of total tax revenues, while 33 states enacted cuts in excess of 3 percent of total tax revenues.1 According to the Center on Budget and Policy Priorities, the tax cuts of the 1990s reduced actual state tax revenues by 8.2 percent from what they otherwise would have been. Nevertheless, actual tax revenues continued to grow throughout the 1990s, thanks to the economic boom. It turned out, however, that states financed permanent tax cuts with the temporary economic boom of the 1990s. In contrast to the 1990-91 recession, when nearly every state raised taxes in response to budget shortfalls, fewer than 20 states have raised taxes since the 2001 recession. And in most cases, the tax increases have focused on relatively narrow and/or shrinking tax bases, such as retail sales and cigarettes.2 Slow economic growth, a weak stock market, an increase in homeland security responsibilities, and a greater reliance on weakening tax bases continue to prolong states’ budget crises. An important question is whether current budget deficits are due entirely to a reduction in revenue, or whether state expenditures have grown at unusually high rates over the past decade. Annual real per capita state expenditures and revenues from 1970 to 2002 are shown in the figure along with recessions as determined by the National Bureau of Economic Research.3 The aggregate state budget deficit is clearly seen at the far right of the figure and is much greater than the deficit associated with the 1990-91 recession. Also, as shown, the growth in real per capita expenditures during the 1990s was not greater than that of earlier decades. In fact, the average annual growth in real per capita state expenditures from 1992 through 2000 was 1.4 percent, compared with 2.5 and 2.3 percent in non-recession years during the 1980s and 1970s, respectively. However, revenue and expenditure data for the past three years reveal that expenditure growth did not slow in the wake of decreasing tax revenues. Real per capita state revenue fell by 0.2 percent in 2000, 1.9 percent in 2001, and 0.7 percent in 2002, whereas real per capita expenditures rose by 1.3 percent, 3.4 percent, and 1.3 percent, respectively. While this scenario occurred during other recessionary periods, as shown in the figure, state budget surpluses prior to this recent recession were smaller than those prior to earlier recessions, thus increasing the chances that a reduction in revenue would lead to a budget deficit.

由于经济的快速增长,美国的州税收在20世纪90年代显著增长。迅速增长的税收,由此产生的预算盈余,以及乐观的收入预测,促使几乎每个州都颁布了大规模的永久性减税政策。10个州的削减幅度在总税收收入的1%到3%之间,33个州的削减幅度超过了总税收收入的3%根据预算和政策优先中心的数据,20世纪90年代的减税措施使实际的州税收收入减少了8.2%。尽管如此,由于经济繁荣,整个20世纪90年代,实际税收收入继续增长。然而,事实证明,各州用20世纪90年代的暂时经济繁荣为永久性减税提供了资金。在1990-91年的经济衰退中,几乎每个州都提高了税收以应对预算短缺,与此形成鲜明对比的是,自2001年经济衰退以来,只有不到20个州提高了税收。在大多数情况下,增税集中在相对狭窄和/或缩小的税基上,如零售和香烟缓慢的经济增长,疲软的股票市场,国土安全责任的增加,以及对疲软的税基的更大依赖,继续延长各州的预算危机。一个重要的问题是,当前的预算赤字是否完全是由于收入减少,还是国家支出在过去十年中以异常高的速度增长。国家经济研究局确定的1970年至2002年的年度实际人均国家支出和收入与经济衰退一起显示在图中。3在图的最右边可以清楚地看到国家预算赤字总额,远远大于1990-91年经济衰退期间的赤字。此外,如所示,1990年代实际人均支出的增长并不比前几十年大。事实上,从1992年到2000年,实际人均国家支出的平均年增长率为1.4%,而在20世纪80年代和70年代,非衰退年份分别为2.5%和2.3%。然而,过去三年的收入和支出数据显示,支出增长并未因税收减少而放缓。2000年、2001年和2002年,实际人均国家收入分别下降了0.2%、1.9%和0.7%,而实际人均支出分别增长了1.3%、3.4%和1.3%。如图所示,虽然这种情况发生在其他经济衰退时期,但最近这次经济衰退之前的国家预算盈余比早期经济衰退之前的国家预算盈余要小,因此增加了收入减少导致预算赤字的可能性。面对经济衰退,各州可能低估了其收入来源的不稳定性。各州开始依赖资本收益、股票期权和奖金收入作为日益增长的税收来源(与普通劳动收入相比)。这些税基受经济周期和股市波动的影响更大。因此,加州等实行高度累进所得税结构的州,不经意间将预算暴露在资本利得、股票期权和奖金收入的周期性波动之下。

Burgeoning tax revenues, the resulting budget surpluses, and rosy revenue forecasts prompted almost every state to enact large permanent tax cuts. Ten states enacted cuts of between 1 and 3 percent of total tax revenues, while 33 states enacted cuts in excess of 3 percent of total tax revenues.1 According to the Center on Budget and Policy Priorities, the tax cuts of the 1990s reduced actual state tax revenues by 8.2 percent from what they otherwise would have been. Nevertheless, actual tax revenues continued to grow throughout the 1990s, thanks to the economic boom. It turned out, however, that states financed permanent tax cuts with the temporary economic boom of the 1990s. In contrast to the 1990-91 recession, when nearly every state raised taxes in response to budget shortfalls, fewer than 20 states have raised taxes since the 2001 recession. And in most cases, the tax increases have focused on relatively narrow and/or shrinking tax bases, such as retail sales and cigarettes.2 Slow economic growth, a weak stock market, an increase in homeland security responsibilities, and a greater reliance on weakening tax bases continue to prolong states’ budget crises. An important question is whether current budget deficits are due entirely to a reduction in revenue, or whether state expenditures have grown at unusually high rates over the past decade. Annual real per capita state expenditures and revenues from 1970 to 2002 are shown in the figure along with recessions as determined by the National Bureau of Economic Research.3 The aggregate state budget deficit is clearly seen at the far right of the figure and is much greater than the deficit associated with the 1990-91 recession. Also, as shown, the growth in real per capita expenditures during the 1990s was not greater than that of earlier decades. In fact, the average annual growth in real per capita state expenditures from 1992 through 2000 was 1.4 percent, compared with 2.5 and 2.3 percent in non-recession years during the 1980s and 1970s, respectively. However, revenue and expenditure data for the past three years reveal that expenditure growth did not slow in the wake of decreasing tax revenues. Real per capita state revenue fell by 0.2 percent in 2000, 1.9 percent in 2001, and 0.7 percent in 2002, whereas real per capita expenditures rose by 1.3 percent, 3.4 percent, and 1.3 percent, respectively. While this scenario occurred during other recessionary periods, as shown in the figure, state budget surpluses prior to this recent recession were smaller than those prior to earlier recessions, thus increasing the chances that a reduction in revenue would lead to a budget deficit. States might have underestimated how volatile their revenue sources would prove to be in the face of a recession.

The chorus from Travis’s 1947 song about the plight of coal miners might ring true for someone looking at average hourly earnings (AHE) of production and nonsupervisory workers. By this measure, as shown in the chart, the pay for an hour of work fell in real terms by 3 percent between 1975 and 2006. Is the average worker actually receiving less per hour of work today than 31 years ago? The answer is likely no. In fact, an alternative measure of compensation, national labor income per hour, increased 44 percent during this period. What accounts for these conflicting results and why do we conclude that the average worker’s real compensation per hour has increased since the mid-1970s? Both the AHE and the national labor income series are adjusted for inflation. However, AHE is adjusted using the consumer price index for all urban wage earners and clerical workers (CPI-W), while national labor income per hour is adjusted using the personal consumption expenditures (PCE) implicit price deflator. To calculate the purchasing power of an hour of work, it is more appropriate to use the PCE implicit price deflator to adjust for inflation because this index better reflects the basket of goods and services actually consumed. Contrary to the CPI-W, which assumes that the same basket of goods and services is purchased for several years, the PCE deflator is calculated using expenditures from the current and preceding period. After applying the PCE deflator, AHE show an 11 percent increase rather than a 3 percent decrease between 1975 and 2006. Another difference in the construction of the two data series is that national labor income per hour includes not only wages and salaries, but also fringe benefits. Given the importance of benefits to a worker’s standard of living, we think many would disagree with the use of the label “fringe.” The benefits of employer contributions to worker’s pension and insurance funds and to government social insurance are included in national labor income per hour, but are not in the AHE series.1 These benefits have become a larger share of worker compensation over time, rising from 14 percent in 1975 to 19 percent in 2006. Once the AHE data are adjusted to include estimated benefits per hour and the PCE deflator is applied, the calculated increase in real wages and benefits reaches 16 percent between 1975 and 2006. Without question, the 16 percent increase in average hourly earnings following the two adjustments described above remains far short of the 44 percent increase in national labor income per hour. What accounts for the remaining difference is unclear. Part of the difference is likely due to the fact that the AHE is restricted to production and nonsupervisory workers. What is clear, however, is that the average worker is receiving more in 2006 for “sixteen tons” than 31 years ago.
对于那些关注生产工人和非管理工人平均时薪(AHE)的人来说,特拉维斯1947年关于煤矿工人困境的歌曲中的副歌部分可能听起来很真实。如图所示,按照这一标准,每小时的工资在1975年至2006年间实际下降了3%。现在普通工人每小时的工资真的比31年前少了吗?答案很可能是否定的。事实上,另一种衡量报酬的方法——每小时国民劳动收入——在此期间增长了44%。是什么导致了这些相互矛盾的结果?为什么我们得出这样的结论:自20世纪70年代中期以来,工人平均每小时的实际报酬有所增加?工人工资指数和国民劳动收入指数都经过通货膨胀调整。然而,AHE使用所有城市工薪阶层和文职人员的消费者价格指数(CPI-W)进行调整,而每小时国民劳动收入使用个人消费支出(PCE)隐性价格平减指数进行调整。为了计算一小时工作的购买力,使用PCE隐性价格平减指数来调整通胀更为合适,因为该指数更好地反映了实际消费的一篮子商品和服务。CPI-W假设几年购买同一篮子商品和服务,与之相反,个人消费支出平减指数是使用当期和上一期的支出来计算的。在应用个人消费支出平减指数后,AHE显示,1975年至2006年间,AHE增长了11%,而不是下降了3%。两个数据序列构建的另一个不同之处在于,国民每小时劳动收入不仅包括工资和薪金,还包括附加福利。考虑到福利对工人生活水平的重要性,我们认为许多人不会同意使用“边缘”这个标签。雇主对职工养老保险基金和政府社会保险的缴款包括在每小时国民劳动收入中,但不包括在AHE系列中随着时间的推移,这些福利在员工薪酬中所占的比例越来越大,从1975年的14%上升到2006年的19%。一旦对AHE数据进行调整,包括每小时的估计福利,并应用个人消费支出平减指数,计算出的实际工资和福利在1975年至2006年间增长了16%。毫无疑问,经过上述两次调整后,平均每小时收入增长了16%,但与全国每小时劳动收入增长44%的水平相比,增幅仍然相距甚远。其余差异的原因尚不清楚。这种差异的部分原因可能是由于AHE仅限于生产和非监督工人。然而,可以肯定的是,2006年,普通工人从“16吨”粮食中获得的收入比31年前要多。
