Why do individuals participate in charitable gambling activities? We conduct a laboratory investigation of a model that predicts risk-neutral expected utility maximizers will participate in lotteries when they recognize that lotteries are being used to finance public goods. As predicted by the model, we find that public goods provision is higher when financed by lottery proceeds than when financed by voluntary contributions. We also find support for other comparative static predictions of the model. In particular we find that ticket purchases vary with the size of the fixed prize and with the return from the public good: lotteries with large prizes are more effective, and ticket purchases drop dramatically when the public good is not valued by subjects.

We study elections in which one party (the strong party) controls a source of political unrest; e.g., this party could instigate riots if it lost the election. We show that the strong party is more likely to win the election when there is less information about its ability to cause unrest. This is because when the weak party is better informed, it can more reliably prevent political unrest by implementing a “centrist” policy. When there is uncertainty over the credibility of the threat, “posturing” by the strong party leads to platform divergence.

Firms' organizational choices are influenced by external conditions such as the instability of the product market. In order to address this issue in a macroeconomic perspective, we embed the firm's choice of organizational structure in a model of growth through creative destruction, which induces endogenous market volatility. We find that an increasing supply of skill or globalization may increase the rate of creative destruction, the skill premium, and the skilled wages, and it may depress the unskilled wages. We use an original data set to test the empirical relevance of our theory.

We study the pricing effects of dividend and earnings announcements by taking advantage of the unique setting in Japan where managers simultaneously announce the current year's dividends and earnings as well as forecasts of next year's dividends and earnings. Defining surprises as deviations from analysts' forecasts, we find that share price reactions are significantly affected by earnings surprises, especially management forecasts of next year's earnings. The information content of dividends is marginal and is restricted to announcements of next year's dividends. Consistent with Modigliani and Miller's dividend irrelevance proposition, current dividend surprises have no material impact on stock prices in Japan.

In this paper we provide insights into the manner in which (relatively sparse) accounting information, along with measures of internet usage, are employed by the market in the valuation of internet firms. Consistent with those who claim that financial statement information is of very limited use in the valuation of internet stocks, we are unable to detect a significant positive association between bottom-line net income and our sample firms’ market prices; in fact, the association is actually negative. However, when we decompose net income into its components, we find gross profits to be positively and significantly associated with prices. In addition, both unique visitors and pageviews, as measures of internet usage, are found in most instances to provide incremental explanatory power (in some cases considerable) for stock prices. We also separately analyze the e-tailers, and the portal and content/community firms (the p/c firms) in our sample. For the e-tailers we find that bottom-line net income generally has a negative association with stock prices (as for the sample as a whole), while a positive and significant association exists for the p/c firms. In this respect, p/c firms’ shares behave more like those of non-internet companies. Further, we find for the p/c firms that the incremental explanatory power of pageviews and of unique visitors is approximately the same; in contrast, pageviews has much greater incremental explanatory power for the e-tailers than does unique visitors. This suggests that pages viewed per visitor is an especially important metric for the e-tailers, as compared to the p/c firms.

A valid Edgeworth expansion is established for the limit distribution of density-weighted semiparametric averaged derivative estimates of single index models. The leading term that corrects the normal limit varies in magnitude, depending on the choice of bandwidth and kernel order. In general this term has order larger than the n−1/2 that prevails in standard parametric problems, but we find circumstances in which it is O(n−1/2), thereby extending the achievement of an n−1/2 Berry-Esseen bound in Robinson (1995a). A valid empirical Edgeworth expansion is also established. We also provide theoretical and empirical Edgeworth expansions for a studentized statistic, where some correction terms are different from those for the unstudentized case. We report a Monte Carlo study of finite sample performance.

We study the consequences of hospital competition for Medicare beneficiaries' heart attack care from 1985 to 1994. We examine how relatively exogenous determinants of hospital choice such as travel distances influence the competitiveness of hospital markets, and how hospital competition interacts with the influence of managed-care organizations to affect the key determinants of social welfare—expenditures on treatment and patient health outcomes. In the 1980s the welfare effects of competition were ambiguous; but in the 1990s competition unambiguously improves social welfare. Increasing HMO enrollment over the sample period partially explains the dramatic change in the impact of hospital competition.

The valuation of debt and equity, reorganization boundaries, and firm's optimal dividend policies are studied in a framework where we model strategic interactions between debt holders and equity holders in a game-theoretic setting which can accommodate varying bargaining powers to the two claimants. Two formulations of reorganization are presented: debt-equity swaps and strategic debt service resulting from negotiated debt service reductions. We study the effects of bond covenants on payout policies and distinguish liquidity-induced defaults from strategic defaults. We derive optimal equity issuance and payout policies. The debt capacity of the firm and the optimal capital structure are characterized.

From bidding data, we estimate the underlying value distribution for Forest Service timber. We find that bidder values decrease $2/mbf (thousand board feet) with each mile from the tract and that small firms (fewer than 500 employees) have values that are $72/mbf lower than large firms. The empirical value distribution is used to simulate various hypothetical scenarios designed to inform public policy. The most anticompetitive mergers raise price by less than 3%, and a 4% decline in marginal costs through greater merger efficiencies is enough to offset a 1% anticompetitive price increase. Eliminating the SBA set-aside program would raise timber revenues by 15%. A policy of granting bidding preferences to small and more-distant bidders would raise revenue by approximately one-tenth of one percent.

We develop a competitive model of trade between countries with similar aggregate factor endowments. The trade pattern reflects differences in the distribution of talent across the labor forces of the two countries. The country with a relatively homogeneous population exports the good produced by a technology with complementarities between tasks. The country with a more diverse workforce exports the good for which individual success is more important. Imperfect observability of talent strengthens the forces of comparative advantage. Finally, we examine the effects of trade on income distribution and the composition of firms in each industry.
