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.     

Insurance Demand Anomalies and Regulation

In recent years, it has become increasingly clear that risk aversion alone cannot explain individuals' demand for insurance. From the perspective of risk aversion, individuals tend to purchase insurance when they should not, refuse to purchase insurance when they should, prefer sub-optimal payouts and allow irrelevant considerations to influence their insurance preferences. This article considers the normative implications of these insurance demand anomalies. It argues that while they are generally the result of consumer mistakes, they may also reflect sophisticated decision making. Given these conflicting explanations, the article explores a spectrum of “libertarian paternalistic” regulatory interventions in insurance markets.     

ON THE ROLE OF CAPITAL GAINS IN SWEDISH INCOME INEQUALITY

Realized capital gains are typically disregarded in the study of income inequality. We show that in the case of Sweden this severely underestimates the actual increase in inequality and, in particular, top income shares during recent decades. Using micro panel data to average incomes over longer periods and re‐rank individuals according to income excluding capital gains, we show that capital gains indeed are a reoccurring addition to rather than a transitory component in top incomes. Doing the same for lower income groups, however, makes virtually no difference. We also try to find the roots of the recent surge in capital gains‐driven inequality in Sweden since the 1980s. While there are no evident changes in terms of who earns these gains (high wage earners vs. top capital income earners), the primary driver instead seems to be the drastic asset price increases on the post‐1980 deregulated financial markets.     

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。     

Discussion of Accounting Discretion in Fair Value Estimates: An Examination of SFAS 142 Goodwill Impairments

Beatty and Weber examine an accounting choice that managers made upon adoption of Statement of Financial Accounting Standards 142: whether to record a goodwill asset impairment as a cumulative effect of an accounting change at the time of adoption or delay the recognition of such an impairment to the future (perhaps indefinitely) when they would be recorded as expenses in earnings from continuing operations. The authors consider several factors that might influence management's reporting of transition effects, including contracting, equity market incentives, and regulatory forces. Participants at the 2005 Journal of Accounting Research Conference questioned whether such a complex accounting decision can be captured with simple linear models and noisy proxy variables, while also speculating upon whether the results would generalize to other settings. In this discussion, I summarize Beatty and Weber's research, highlight its contribution to the accounting literature, and provide a record of the main issues raised by the conference participants.     

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.     

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.
