Determinants of Research and Development Activity by Electric Utilities: Comment 电力公司研究和发展活动的决定因素:评论
Pub Date : 1900-01-01 DOI: 10.2307/3003286
J. B. Delaney, T. Honeycutt
This comment examines a model of the determinants of electric utility R&D activity postulated by Wilder and Stansell. One of the defects in their empirical analysis is the failure to account for corporate interrelationships among the sample observations. Wilder and Stansell include as separate and independent observations joint venture companies, operating systems of holding companies, and subsidiaries of nonutility parent companies. After adjusting the original sample for these corporate affiliations, we estimated the Wilder and Stansell model for 1970 and 1972. Our empirical results do not support the Wilder and Stansell conclusion regarding the impact of current profitability on current research and development activity. We find that the sign and significance of the profitability measure are sensitive to the composition of the sample and to the particular time frame.
这篇评论考察了由Wilder和Stansell假设的电力公司研发活动的决定因素模型。他们的实证分析的缺陷之一是未能解释样本观察之间的企业相互关系。Wilder和Stansell将合资公司、控股公司的运营系统和非公用事业母公司的子公司包括在内。在调整了这些公司关系的原始样本后,我们估计了1970年和1972年的Wilder和Stansell模型。我们的实证结果不支持Wilder和Stansell关于当前盈利能力对当前研发活动影响的结论。我们发现盈利能力指标的符号和显著性对样本的组成和特定的时间框架都很敏感。

Bank Holding Company Diversification and the Risk of Capital Impairment 银行控股公司多元化与资本减值风险
Pub Date : 1900-01-01 DOI: 10.2307/3003359
David R. Meinster, Rodney D. Johnson
The 1970 Amendments to the Bank Holding Company Act have empowered the Federal Reserve Board to determine whether the bank holding company expansions into nonbank activities meet the "proper incident" test. This paper presents an analytical device whereby regulators applying this test can evaluate the effects that each proposed nonbank expansion has upon the holding company's probability of capital impairment and debt capacity. Several regulatory implications are derived. The procedure is simulated and the separate effects of diversification and debt financing are measured. While the holding companies studied diversified effectively, the benefits were largely thwarted by considerable debt financing.
1970年《银行控股公司法》修正案授权联邦储备委员会决定银行控股公司向非银行业务的扩张是否符合“适当事件”的测试。本文提出了一种分析工具,监管机构可以利用这种测试来评估每个拟议的非银行扩张对控股公司资本减值和债务能力的影响。得出了几个监管含义。模拟了这一过程,并分别衡量了多元化和债务融资的影响。虽然研究的控股公司有效地实现了多元化,但其收益在很大程度上受到了大量债务融资的阻碍。

Differential Pricing and Interconsumer Efficiency in the Electric Power Industry 电力行业的差别定价和消费者间效率
Pub Date : 1900-01-01 DOI: 10.2307/3003205
J. Crockett
As a means of avoiding the allocative distortions which might arise from pricing uniformly all units of output, industries in the regulated sector commonly utilize a variety of differential pricing practices. This paper presents empirical evidence indicating that one variant of differential pricing used in the electric power industry in itself gives rise to substantial allocative inefficiency. This finding suggests that the welfare consequences of differential pricing be examined more carefully.
为了避免因对所有产出单位统一定价而可能造成的配置扭曲,受管制部门的工业通常采用各种差别定价做法。本文提出的实证证据表明,电力行业中使用的差异定价的一种变体本身就导致了大量的配置效率低下。这一发现表明,差别定价对福利的影响需要更仔细地研究。

Metering Costs and Marginal Cost Pricing in Public Utilities 公用事业计量成本与边际成本定价
Pub Date : 1900-01-01 DOI: 10.2307/3003083
G. F. Mathewson, G. D. Quirin
This paper examines a welfare criterion for marginal cost pricing in the presence of metering costs. The good examined is local telephone service, which is viewed as two separate commodities: a connection to the system, and a charge for the telephone services actually used. The empirical results suggest that the rate structures of North American telephone utilities appear more consistent with rational pricing in the face of metering costs than with Averch-Johnson behavior.
本文研究了计量成本存在时边际成本定价的福利标准。所审查的商品是本地电话服务,它被视为两个独立的商品:与系统的连接和实际使用电话服务的费用。实证结果表明,面对计量成本,北美电话公用事业公司的费率结构似乎更符合理性定价,而不是与艾弗里-约翰逊行为相一致。

Risk Sharing and the Theory of the Firm 风险分担与企业理论
Pub Date : 1900-01-01 DOI: 10.2307/3003460
A. Marcus
When effort cannot be costlessly monitored, Pareto optimal employee compensation schemes require that owners and managers deviate from perfect risk sharing to improve the work incentives facing the manager. This article investigates the implications of this misallocation of risk for the behavior of firms in which managers make decisions for owners. The presented model predicts that, from the owner's perspective, managers will exhibit excessive risk aversion and underinvest in risky projects.

The economic feasibility of shale oil: an activity analysis 页岩油的经济可行性:活动分析
Pub Date : 1900-01-01 DOI: 10.2307/3003593
Neil R. Ericsson, Peter J. Morgan
Given the current state of technology, the existing resource supplies, and environmental constraints, we examine how much shale oil could be profitably produced in the Western United States, what processes would be used, and which constraints would be binding in long-run equilibrium. Using an activity analysis model, we show that production of over 15 million barrels of shale oil per day (five-sixths of present U.S. oil consumption) is a profitable activity when the price of oil is $18 per barrel (1975 dollars). In testing the sensitivity of our results, we find that, even under quite conservative assumptions, production of two million barrels per day is economically feasible in the long run when the selling price of oil exceeds $12 per barrel.
考虑到目前的技术状况、现有的资源供应和环境限制,我们将研究在美国西部可以生产多少页岩油,将使用哪些工艺,以及哪些限制将在长期平衡中具有约束力。使用活动分析模型,我们表明,当油价为每桶18美元(1975年美元)时,每天生产超过1500万桶页岩油(目前美国石油消费量的六分之五)是一项有利可图的活动。在测试我们结果的敏感性时,我们发现,即使在非常保守的假设下,当石油售价超过每桶12美元时,从长远来看,每天生产200万桶在经济上是可行的。

Self-selection by contractual choice and the theory of sharecropping 契约选择的自我选择与分成制理论
Pub Date : 1900-01-01 DOI: 10.2307/3003586
W. Hallagan
There are definite patterns for the organization of production on agricultural land. Production of some crops tends to be organized via wage contracts, while land sown to other crops tends to be rented, and still other crops are frequently sharecropped. One popular explanation is that contractual choice in agriculture is related to the riskiness of production. Sharecropping, according to this argument, is used with the most risky crops to facilitate risk spreading in a world with incomplete insurance markets.
农业用地的生产组织有一定的模式。一些作物的生产往往是通过工资合同来组织的,而播种其他作物的土地往往是租来的,还有一些作物经常是分成的。一种流行的解释是,农业中的合同选择与生产的风险有关。根据这种观点,在一个保险市场不完善的世界里,分成制被用于风险最高的作物,以促进风险的扩散。

Misinformation and Regulatory Actions in the Canadian Capital Markets: Some Empirical Evidence 加拿大资本市场中的错误信息和监管行动:一些经验证据
Pub Date : 1900-01-01 DOI: 10.2307/3003587
L. Kryzanowski
In this paper the effect of allegedly manipulative activities on stock returns and the effectiveness of trading suspensions in arresting such manipulations are empirically studied. The results from conducting both a Fama-Fisher-Jensen-Roll test and a portfolio test on the error terms computed from a single factor market in periods surrounding a trading suspension are presented. The findings clearly identify regulators as having access to predominantly unfavorable new information about allegedly manipulative activities that is not "fully reflected" in stock prices prior to a trading suspension. Furthermore, since unfavorable information disclosures during a trading suspension period are found not to be fully reflected in stock prices on the date of trading reinstatement, the market is deemed to be inefficient in the semistrong form.
本文实证研究了涉嫌操纵行为对股票收益的影响以及停牌对阻止此类操纵行为的有效性。本文给出了对单因素市场在交易暂停期间计算的误差项进行Fama-Fisher-Jensen-Roll检验和投资组合检验的结果。调查结果清楚地表明,监管机构获得的主要是不利的、有关涉嫌操纵行为的新信息,而这些信息在停牌前没有“充分反映”在股价中。此外,由于停牌期间的不利信息披露没有充分反映在复牌当日的股价中,因此市场被认为是半强形式的低效市场。

This article demonstrates that the partitioning of economic activity into for-profit and nonprofit organizations can be at least partially described as the solution to an optimal contracting problem. We show that nonprofit firms may be superior to for-profit firms if the output cannot be costlessly observed.

Prospects for Cable in the 100 Largest Television Markets 有线电视在100个最大电视市场的前景
Pub Date : 1900-01-01 DOI: 10.2307/3003073
R. E. Park
The Federal Communications Commission, hoping "to get cable moving without jeopardizing over-the-air broadcasting," recently proposed rules that would allow cable systems in the 100 largest television markets to carry a limited number of distant signals. This paper employs a nonlinear model of cable penetration to assess the effect of the proposed rules. The model is developed using a sample of 63 cable systems located where several signals can be received over the air with no particular reception problems. Applying the model to some typical top-100 market situations, the author concludes that the proposed rules "will meet the Commission's objective. But more is necessary to keep cable moving, because the rules by themselves are probably not sufficient to make cable profitable in most of the top-100 markets. To succeed in the cities, cable must attract customers with new services in addition to the traditional package of better reception plus distant signals."
美国联邦通信委员会(Federal Communications Commission)希望“在不影响无线广播的情况下推进有线电视的发展”,最近提出了一项规定,允许100个最大电视市场的有线电视系统传输有限数量的远距离信号。本文采用缆索穿透的非线性模型来评估所提出规则的效果。该模型是使用63个电缆系统的样本开发的,这些系统可以通过空中接收几个信号,没有特别的接收问题。将该模型应用于一些典型的前100名市场情况,作者得出结论,拟议的规则“将达到委员会的目标。但要保持有线电视的发展,还需要更多的措施,因为这些规则本身可能不足以使有线电视在大多数前100大市场中盈利。为了在城市中取得成功,有线电视必须以新的服务吸引客户,除了传统的更好的接收和远距离信号的套餐。”
