We examine the problem of how much risk‐averse agents would be willing to bet on events where there are multiple possible winners but only one will actually win. We describe how this problem can be solved for concave utility functions and illustrate the properties of the solution. The optimal betting strategy is more aggressive than strategies derived from considering each outcome separately such as the Kelly criterion. The strategy also recommends sometimes placing bets with negative expected returns because they act as hedges against losses on other bets. While this strategy maximizes the bettor's subjective expected utility, if betting odds incorporate a profit margin and reflect underlying probabilities correctly, then this more aggressive approach loses more money and results in lower realized utility.
我们研究的问题是,在有多个可能的赢家但实际上只有一个会赢的情况下,规避风险的代理人愿意下多大的赌注。我们描述了如何解决凹效用函数问题,并说明了解决方案的特性。最佳投注策略比凯利准则等分别考虑每种结果得出的策略更为激进。该策略还建议有时下注预期收益为负的赌注,因为这些赌注可以对冲其他赌注的损失。虽然这种策略能使投注者的主观预期效用最大化,但如果投注赔率包含利润率并能正确反映基本概率,那么这种更激进的方法会损失更多资金,导致实现效用降低。

Much of the economic literature on education models the process of acquiring human capital as a “black box.” While such models have many interesting uses, they are of little use when a student is considering how much teaching she needs and how her time at university is allocated between study and attending class. Considering such questions requires us to “open up” the black box. Our paper shows what one such model would look like by explicitly modeling how students choose to learn. We believe that this framework can inform the current debate about teaching in higher education.
许多关于教育的经济文献都将人力资本的获取过程视为一个 "黑箱"。虽然这种模型有许多有趣的用途,但当学生考虑她需要多少教学,以及如何在学习和上课之间分配她在大学的时间时,这些模型就没有什么用处了。考虑这些问题需要我们 "打开 "黑箱。我们的论文通过明确模拟学生如何选择学习,展示了这样一个模型。我们相信,这一框架可以为当前有关高等教育教学的讨论提供参考。

Household assets and business cycle fluctuations 家庭资产和商业周期波动
IF 0.8 4区 经济学 Q3 ECONOMICS Pub Date : 2024-08-05 DOI: 10.1111/boer.12469

This paper shows that an increase in the ratio of household assets to gross domestic product (GDP) predicts higher GDP growth in the short term, but lower growth in the long term. It is also associated with lower consumption, investment, and employment rates in the future. The result is robust to controlling for various economic indicators including credit spreads, household debt to GDP ratio, and leverage ratio. Finally, we estimate a structural vector autoregressive model and find that an increase in the interest rate is associated with a decrease in the household assets to GDP ratio, in contrast to the findings of Galí and Gambetti (2015, American Economic Journal: Macroeconomics, 7(1), 233–257). This appears to support the conventional view of monetary policy.
本文表明,家庭资产与国内生产总值(GDP)之比的增加可预测短期内较高的 GDP 增长率,但长期增长率较低。它还与未来较低的消费、投资和就业率有关。这一结果在控制各种经济指标(包括信贷利差、家庭债务与国内生产总值之比以及杠杆率)后是稳健的。最后,我们估计了一个结构性向量自回归模型,发现利率上升与家庭资产与GDP比率下降相关,这与Galí和Gambetti(2015年,《美国经济学报》:宏观经济学》,7(1),233-257)的结论相反。这似乎支持了传统的货币政策观点。

In this study, we investigate the relationship between debt governance and overinvestment. We use net cash flows to debtholders as a proxy for debt governance and find that an increase in these cash flows mitigates firms' overinvestment. We also show that free cash flows lead cash-rich and cash-poor firms to overinvest but that debt governance attenuates this problem. Finally, we find that the mitigating effect of net cash flows to debtholders on overinvestment is highly pronounced in firms with poor governance. These findings suggest that net cash flows to debtholders are particularly effective when shareholder governance is weak. We conclude that cash flows to debtholders can effectively prevent overinvestment and reduce the agency costs of free cash flows.

在本研究中,我们探讨了债务治理与过度投资之间的关系。我们使用流向债务持有人的净现金流量作为债务治理的替代指标,并发现这些现金流的增加会缓解企业的过度投资。我们还发现,自由现金流会导致现金充裕和现金不足的公司过度投资,但债务治理会缓解这一问题。最后,我们发现,对债务人的净现金流对过度投资的缓解作用在治理不善的公司中非常明显。这些发现表明,当股东治理薄弱时,向债务人提供净现金流尤其有效。我们的结论是,向债务人提供现金流可以有效防止过度投资,降低自由现金流的代理成本。

We offer a simple formalization of different types of flexible working time arrangements. Specifically, we study the distinction between employee-oriented flexibility and employer-oriented flexibility. The formal framework we offer can be useful in formulating hypotheses for the growing body of empirical work in the area.

Why the Feldstein–Horioka “puzzle” remains unsolved 费尔德斯坦-堀冈之 "谜 "为何仍未解开

We argue that the 40-year-old Feldstein–Horioka “puzzle” should have never been labeled as such. We discuss two problems with the literature. First, we show that the series of investment and saving rates typically used in empirical exercises to test the Feldstein–Horioka thesis are not appropriate. The correct series to properly test it are not collected. Second, we show that the Feldstein–Horioka regression is not a model in the econometric sense, that is, an equation with a proper error term (a random variable). The reason is that by adding the capital account to their regression, one gets the accounting identity that relates the capital account, domestic investment, and domestic saving. This implies that the estimate of the coefficient of the saving rate in the Feldstein–Horioka regression can be thought of as a biased estimate of the same coefficient in the accounting identity, where it has a value of 1. Because the omitted variable is known, we call it pseudo bias. Given that this (pseudo) bias is known to be negative and less than 1 in absolute terms, it should come as no surprise that the Feldstein–Horioka regression yields a coefficient between 0 and 1.

我们认为,已有 40 年历史的费尔德斯坦-堀冈 "谜题 "从来就不应该被贴上这样的标签。我们讨论了文献中的两个问题。首先,我们表明,在检验费尔德斯坦-堀冈理论的实证研究中,通常使用的投资率和储蓄率序列是不恰当的。我们没有收集到正确检验该理论的正确序列。其次,我们表明费尔德斯坦-堀冈回归并不是计量经济学意义上的模型,即带有适当误差项(随机变量)的方程。原因在于,通过在回归中加入资本账户,我们可以得到将资本账户、国内投资和国内储蓄联系起来的会计特征。这意味着费尔德斯坦-堀冈回归中储蓄率系数的估计值可以看作是会计特征中同一系数的有偏估计值,其值为 1。鉴于这种(伪)偏差已知为负值且绝对值小于 1,费尔德斯坦-堀冈回归得出的系数介于 0 和 1 之间也就不足为奇了。

This study examines the impact of fiscal autonomy (FAP) on public expenditure performance across 18 Indian states from 2010–11 to 2019–20. We develop a measure of public expenditure performance using social indicators. We also measure FAP using revenue-expenditure ratio. Based on system generalized method of moments, the empirical result confirms that a higher FAP given to Indian states is associated with greater fiscal performance. Further, the robustness check reveals that central transfer insignificantly affects the expenditure performance of Indian states.

本研究探讨了印度 18 个邦在 2010-11 年至 2019-20 年期间财政自治(FAP)对公共支出绩效的影响。我们使用社会指标来衡量公共支出绩效。我们还使用收入支出比来衡量 FAP。基于系统广义矩法,实证结果证实,给予印度各邦更高的 FAP 与更高的财政绩效相关。此外,稳健性检验显示,中央转移支付对印度各邦的支出绩效影响不大。

How rising housing prices affect labor costs in China: Heterogeneity and lagging 房价上涨如何影响中国劳动力成本:异质性和滞后性

The impact of house prices rising on urban labor costs has typical heterogeneity and lag effects, but there is little literature on it. Based on the panel data of 283 prefecture level cities from 2001 to 2017, we constructed panel model considering lag effect and threshold effect. The results show that lag one period of housing price has significant positive impact on urban labor costs, with the increase of housing prices, the effect of pushing up the current labor costs is gradually increasing. So, this impact has obvious lag effect and threshold effect. Through grouped regression to test heterogeneity effect, at the regional level, the heterogeneity of the impact is more significant. The more developed the economy is, the greater the pushing effect of house prices on labor costs.

房价上涨对城市劳动力成本的影响具有典型的异质性和滞后效应,但相关文献较少。基于2001-2017年283个地级市的面板数据,我们构建了考虑滞后效应和门槛效应的面板模型。结果表明,滞后一期的房价对城市劳动力成本具有显著的正向影响,随着房价的上涨,推高当期劳动力成本的效应逐渐增强。因此,这种影响具有明显的滞后效应和门槛效应。通过分组回归检验异质性效应,在地区层面,异质性影响更为显著。经济越发达,房价对劳动力成本的推动作用越大。

Identifying the effects of quantitative easing (QE) on asset return correlations is critical to assessing such policies’ impact across financial markets. In this paper, we use a dynamic conditional correlation model that allows us to measure the impact of unconventional monetary policy on time-varying correlations. Our results suggest that QE significantly affected correlations between stocks and bonds after the Great Recession via short-term portfolio balance effects. The findings are critical for policy-makers and practitioners alike. Central banks should consider the impact of monetary policy on asset correlations in their cost–benefit analyses. Likewise, portfolio managers are encouraged to factor in the effects of monetary policy on correlations to optimize portfolios and reduce potential losses strategically.

确定量化宽松政策(QE)对资产收益相关性的影响对于评估此类政策对整个金融市场的影响至关重要。在本文中,我们使用动态条件相关性模型来衡量非常规货币政策对时变相关性的影响。我们的研究结果表明,大衰退之后,量化宽松政策通过短期投资组合平衡效应极大地影响了股票和债券之间的相关性。这些发现对政策制定者和实践者都至关重要。中央银行应在成本效益分析中考虑货币政策对资产相关性的影响。同样,我们也鼓励投资组合经理考虑货币政策对相关性的影响,以优化投资组合,战略性地减少潜在损失。

This study delves into the intricate dynamics of technology, labor markets, and economic growth within the context of Industry 4.0. By integrating automation capital into a dynamic general equilibrium model, we examine its implications for economic performance and social equity. The empirical analysis highlights the substitutability of unskilled labor by automation, revealing a nuanced relationship between automation adoption, the skill premium, and economic growth. Contrary to conventional wisdom, our findings suggest that a reduced ratio of unskilled to skilled labor, driven by automation, can lead to both an increase in the skill premium and sustained economic growth, even in the face of demographic challenges such as declining populations. However, this trend also exacerbates income inequality, underscoring the imperative for policy interventions aimed at promoting skill enhancement and ensuring equitable distribution of technological advancements.

本研究深入探讨了工业 4.0 背景下技术、劳动力市场和经济增长的复杂动态。通过将自动化资本纳入动态一般均衡模型,我们研究了其对经济表现和社会公平的影响。实证分析强调了自动化对非熟练劳动力的替代性,揭示了自动化应用、技能溢价和经济增长之间的微妙关系。与传统观点相反,我们的研究结果表明,在自动化的推动下,非熟练劳动力与熟练劳动力的比例降低,即使在面临人口减少等人口挑战的情况下,也能带来技能溢价的增加和经济的持续增长。然而,这一趋势也加剧了收入不平等,凸显了旨在促进技能提升和确保技术进步公平分配的政策干预的必要性。
