LEGAL CORRUPTION

We challenge the conventional definition of corruption through the analysis of legal forms of corruption, and by devoting special attention to influence induced by the private sector. This paper studies the determinants of the world pattern of legal and illegal corruption by proposing a simple theoretical model of endogenous corruption and related legal framework, and its thorough empirical test. Three types of equilibrium outcomes are identified: one based on illegal corruption, where the elite does not face any binding incentives to limit corruption; one centered around legal corruption, where the elite must incur a cost to legally protect corruption; and finally a no‐corruption outcome, where the population is able to effectively react to corruption. Testable implications from the model are derived based on country‐wide parameters. Crucially, we use a rich corporate survey, including 8,279 firms in 104 countries, tailored for this research, and featuring measures of legal corruption that are novel to the literature. The microdimension of the database enables improving on familiar shortcomings associated with the use of endogeneity‐prone, country‐wide indices of perceived corruption. The empirical results, making use of a broad range of proxies and sources, generally validate the model's explanations.     

Learning to Wait: A Laboratory Investigation

Human subjects decide when to sink a fixed cost C to seize an irreversible investment opportunity whose value V is governed by Brownian motion. The optimal policy is to invest when V first crosses a threshold V * = (1 + w *) C , where the wait option premium w * depends on drift, volatility, and expiration hazard parameters. Subjects in the Low w * treatment on average invest at values quite close to optimum. Subjects in the two Medium and the High w * treatments invested at values below optimum, but with the predicted ordering, and values approached the optimum by the last block of 20 periods.     

CASELOAD IMPACTS OF WELFARE REFORM

A welfare reform demonstration program designed to reduce Aid to Families with Dependent Children (AFDC) recidivism through increased employment and training services resulted in significantly higher short-term caseload growth. Demonstration sites attracted proportionally more households onto assistance early in the demonstration than did comparison sites. These entrants tended to have more extensive previous employment histories. This result suggests that the demonstration attracted individuals who previously qualified for AFDC but did not apply for benefits and/or individuals who reduced their employment to qualify for AFDC. Exits from AFDC also were delayed under the demonstration, suggesting that the more intensive services provided through the demonstration required more time to complete. Finally, certain groups—nonwhites and those with language problems, for example—apparently avoided the demonstration by not migrating into demonstration sites or by migrating out of demonstration sites. These results have important implications for the likely costs of state welfare reform efforts under the Family Support Act of 1988 .     

INCREASED INDUSTRIAL USES OF AGRICULTURAL COMMODITIES POLICY, TRADE AND ETHANOL

Using agricultural feedstocks for industrial products affects domestic and international agricultural markets, all of which are encumbered with complex policies. This article examines the interaction of three seemingly unrelated policies: the Clean Air Act, the U.S. corn program, and European Union agricultural subsidies. More ethanol production, resulting from new regulations associated with the Clean Air Act, increases the use of U.S. corn and increases the supply of corn gluten feed, an ethanol co-product. Corn gluten feed is primarily exported to Europe under a loophole in European Union trade barriers. But recent reform of European Union farm policy will lower the price of the European grain for which corn gluten feed is a substitute. This development lowers prices for a major ethanol co-product and thus makes ethanol itself less profitable just as the demand for the fuel is expanding. NAFTA, GATT, and new technologies also play cameo roles in the story .     

Measuring Mutual Fund Performance with Characteristic-Based Benchmarks

This article develops and applies new measures of portfolio performance which use benchmarks based on the characteristics of stocks held by the portfolios that are evaluated. Specifically, the benchmarks are constructed from the returns of 125 passive portfolios that are matched with stocks held in the evaluated portfolio on the basis of the market capitalization, book-to-market, and prior-year return characteristics of those stocks. Based on these benchmarks, “Characteristic Timing” and “Characteristic Selectivity” measures are developed that detect, respectively, whether portfolio managers successfully time their portfolio weightings on these characteristics and whether managers can select stocks that outperform the average stock having the same characteristics. We apply these measures to a new database of mutual fund holdings covering over 2500 equity funds from 1975 to 1994. Our results show that mutual funds, particularly aggressive-growth funds, exhibit some selectivity ability, but that funds exhibit no characteristic timing ability.     

Calculating The Cost of Capital of an Unlevered Firm For Use in Project Evaluation

The adjusted present value requires an estimate of the cost of equity of an unlevered firm. Traditional approaches for calculating this cost assume that firms maintain a constant market-value percentage of debt when in fact firms typically use a book-value percentage of debt. In this paper, we present an approach to correctly estimate the cost of equity of an unlevered firm whenever the firm fails to maintain a constant market-value-based leverage ratio. We also demonstrate that both the Modigliani and Miller (1963) and Miles and Ezzell (1980) approaches may yield substantial valuation errors when firms determine debt levels based on book-value percentages. In contrast our method makes no errors as long as managers know the marginal tax benefit of debt.     

Drilling and Debt

This paper documents a previously unrecognized debt-related investment distortion. Using detailed project-level data for 69 firms in the oil and gas industry, we find that highly levered firms pull forward investment, completing projects early at the expense of long-run project returns and project value. This behavior is particularly pronounced prior to debt renegotiations. We test several channels that could explain this behavior and find evidence consistent with equity holders sacrificing long-run project returns to enhance collateral values and, by extension, mitigate lending frictions at debt renegotiations.     

PENNIES FROM EBAY: THE DETERMINANTS OF PRICE IN ONLINE AUCTIONS*

This paper presents an exploratory analysis of the determinants of prices in online auctions for collectible United States one‐cent coins at the eBay web site. Starting with an initial data set of 20,000 auctions, we perform regression analysis on a restricted sample of 461 coins for which we obtained estimates of book value. We have three major findings. First, a seller's feedback ratings, reported by other eBay users, have a measurable effect on her auction prices. Negative feedback ratings have a much greater effect than positive feedback ratings do. Second, minimum bids and reserve prices have positive effects on the final auction price. In particular, minimum bids appear only to have a significant effect when they are binding on a single bidder, as predicted by theory. Third, when a seller chooses to have her auction last for a longer period of days, this significantly increases the auction price on average.     

人民币为中国消费者而“升”

【美国《华尔街日报》6月16日】眼下中美官员都在为新一轮中美战略经济对话（trategic Economic Dialogue）做着准备，像过去一样，人民币汇率升值仍将是双方会谈中的一个重要议题。在一些具有历史意义的偶然性因素之中，美国财政部长鲍尔森（Hank Paulson）在人民币升值问题上可能会无意间得到一个隐形推手的帮助，那就是以美元计价的原材料成本的涨价风潮，而原材料对于中国的经济发展来说至关重要。
