Many consider improved dispute settlement one of the leading achievements of the WTO. This paper tests the implication of a game-theoretic approach that predicts that more efficient litigation devices increase the frequency and number of trade disputes. We propose an empirical event history analysis of GATT, WTO, and USTR Section 301 cases, identify the demographic patterns for births and lifespans of U.S. disputes, and test the hypothesis of a WTO structural break. The evidence supports the view that the WTO increased the incidence of U.S. trade disputes, while shortening their lifespan.

Abstract This paper examines the value of analysts as industry specialists. We show analysts create value in their recommendations mainly through their ability to rank stocks within industries. An industry-based recommendation strategy substantially improves the return to risk ratio and reduces price momentum tilt relative to portfolios that ignore industry information. An examination of the links among analyst information, aggregated at the industry level, and industry returns and industry momentum shows that industry returns precede industry-aggregated analyst upgrades and downgrades, and the short-term industry price momentum phenomenon is partly explained by returns of firms with more analyst coverage leading those with less in that industry. Recommendation information is not valuable for predicting future relative industry returns, however.
There is widespread evidence supporting the conjecture that borrowing constraints have important implications for firm growth and survival. In this paper we model a multiperiod borrowing/lending relationship with asymmetric information. We show that borrowing constraints emerge as a feature of the optimal long-term lending contract, and that such constraints relax as the value of the borrower's claim to future cash flows increases. We also show that the optimal contract has interesting implications for firm dynamics. In agreement with the empirical evidence, as age and size increase, mean and variance of growth decrease, and firm survival increases.
Contrary to Miller and Modigliani [1961. Dividend policy, growth, and the valuation of shares. Journal of Business 34, 411–433], payout policy is not irrelevant and investment policy is not the sole determinant of value, even in frictionless markets. MM ask “Do companies with generous distribution policies consistently sell at a premium above those with niggardly payouts?” But MM's analysis does not address this question because the joint effect of their assumptions is to mandate 100% free cash flow payout in every period, thereby rendering “niggardly payouts” infeasible and forcing distributions to a global optimum. Irrelevance obtains, but in an economically vacuous sense because the firm's opportunity set is artificially constrained to payout policies that fully distribute free cash flow. When MM's assumptions are relaxed to allow retention, payout policy matters in exactly the same sense that investment policy does. Moreover (i) the standard Fisherian model is empirically refutable, predicting that firms will make large payouts in present value terms, (ii) only when payout policy is optimized will the present value of distributions equal the PV of project cash flows, (iii) the NPV rule for investments is not sufficient to ensure value maximization, rather an analogous rule for payout policy is also necessary, and (iv) Black's [1976. The dividend puzzle. Journal of Portfolio Management 2, 5–8] “dividend puzzle” is a non-puzzle because it is rooted in the mistaken idea that MM's irrelevance theorem applies to payout/retention decisions, which it does not.

Emerging equity markets witness occasional surges in prices (frenzies) and cross-market price dispersion (herds), accompanied by abundant media coverage. An information market complementarity can explain these anomalies. Because information has high fixed costs, high volume makes it inexpensive. Low prices induce investors to buy information that others buy. Given two identical assets, investors learn about one; abundant information reduces its payoff risk and raises its price. Transitions between low-information/low-asset-price and high-information/high-asset-price equilibria resemble frenzies. Equity data and new panel data on news coverage support the model's predictions: Asset market movements generate news and news raises prices and price dispersion.
We explore whether the relation between stock splits and clientele is driven by binding tick sizes. We find little evidence that firms adjusted prices to maintain similarly binding tick sizes as the NYSE reduced tick sizes. Furthermore, though splits that increase the extent to which tick sizes are binding are associated with greater increases in spreads, these splits experience similar changes in measures related to clientele, including trade size, breadth of individual and institutional ownership, and analyst following. We find little evidence supporting theories, such as spread-induced sponsorship, that rely on binding tick sizes to link splits and clientele.
We focus on the relations among inside ownership, board composition, unaffiliated block ownership, and compensation structure for a sample of firms following their IPOs. Specifically, we follow firms for up to eleven years after their IPOs and examine the full sample and subsamples of firms that survive, are acquired, or that file for bankruptcy during the sample period. We find that as CEO ownership declines, board independence, board seats held by venture capitalists, and unaffiliated block ownership increase. Our findings suggest that as inside ownership decreases alternative governance mechanisms evolve to help mitigate the resulting increase in agency costs. Interestingly, the associations between CEO ownership, the fraction of venture capital board membership, and unaffiliated block ownership exist only for firms that survive over the eleven-year sample period.
In this paper we present estimates of Korean bank inefficiency and productivity change for the period 1992–2002 that are derived from the directional technology distance function. Our method controls for loan losses that are an undesirable by-product arising from the production of loans and allows the aggregation of individual bank inefficiency and productivity growth to the industry level. Our findings indicate that technical progress during the period was more than enough to offset efficiency declines so that the banking industry experienced productivity growth.

We investigate market behavior in a setting where managerial incentives to manipulate earnings and market price should be apparent ex ante to market participants. We find evidence of abnormally low discretionary accruals in the period following announcements of cancellations of executive stock options up to the time the options are reissued. Nevertheless, analysts and investors are not misled. Discretionary accruals have little power in explaining stock price performance during this period. Moreover, discretionary accruals do not explain subsequent analyst forecast errors. Thus, our findings suggest that, in this transparent setting, analysts and investors do not respond to earnings management.
