On theoretical grounds, monitoring of top executives by the (supervisory) board is expected to be value relevant. The empirical evidence is ambiguous and we analyze three non-competing explanations for this ambiguity: (i) The positive effect on firm value of board monitoring is hidden in stock price effects due to the simultaneous occurrence of the positive real effect of monitoring and the opposing information effect. (ii) The combination of board monitoring and monitoring by other parties prevents assessing the value relevance of board monitoring in isolation. (iii) The confounding effect of a simultaneous successor appointment typically generates an upward biased estimate. Based on an analysis of price effects and trading volumes at announcement, we conclude that monitoring by the supervisory board is valued by investors: Forced departures of executive directors, also without a successor appointment, are value relevant in the Netherlands where external control mechanisms and shareholder control were virtually absent in the period studied (1991–2000).

This paper examines the measurement of non-financial assets in imperfectly competitive markets and considers the effect of alternative measurements on firms' investing and operating activities. We analyze a duopoly where each firm manufactures, reports, and thereafter sells its inventory. We initially characterize the informativeness of a firm's accounting report when it is prepared using historical cost and find a firm's report does not always reveal its level of inventory. We then characterize the informativeness of a report when it is prepared using fair value and find it completely reveals a firm's inventory holding. We highlight the difficulty of implementing fair value measurements that arise because fair value is an endogenous consequence of the strategic interaction between firms.

The lock-in effect proposes that capital gains taxes represent transaction costs that increase the reservation price for security owners and, ceteris paribus, reduce trading volume. Consistent with the lock-in effect, previous empirical research documents price and reactions to enacted changes in the capital gains tax rate. We investigate whether the volume hypothesis predicted by the lock-in effect extends to corporate acquisition activity. In particular, we analyze whether aggregate corporate acquisition activity is inversely associated with shareholder capital gains tax rates. We measure quarterly corporate acquisition activity from 1973 through 2001 using (1) the percentage of traded firms acquired in a calendar quarter and (2) the percentage of market value of traded firms acquired in a calendar quarter. In supplemental analysis, we measure acquisition activity at the industry level (i.e., as the percentage of firms and percentage of market value acquired by industry annually). In each analysis we model acquisition activity as a function of the maximum long-term capital gains tax rate for individuals and other macroeconomic factors previously hypothesized to be associated with acquisition activity. Consistent with a lock-in effect for corporate acquisitions, we find a significant negative association between corporate acquisition activity and the capital gains tax rate whether we measure acquisition activity in the aggregate or at the industry level. In addition, we find that this negative association is attributable to increased (decreased) taxable acquisition activity during periods of low (high) capital gains tax rates. These results suggest that, ceteris paribus, capital gains taxes represent significant transaction costs that influence the level of corporate acquisition activity.

We investigate cross-country determinants of private credit, using new data on legal creditor rights and private and public credit registries in 129 countries. Both creditor protection through the legal system and information-sharing institutions are associated with higher ratios of private credit to gross domestic product, but the former is relatively more important in the richer countries. An analysis of legal reforms shows that credit rises after improvements in creditor rights and in information sharing. Creditor rights are remarkably stable over time, contrary to the hypothesis that legal rules are converging. Finally, legal origins are an important determinant of both creditor rights and information-sharing institutions. The analysis suggests that public credit registries, which are primarily a feature of French civil law countries, benefit private credit markets in developing countries.

This paper develops and tests a model of how country characteristics, such as legal protections for minority investors and the level of economic and financial development, influence firms’ costs and benefits in implementing measures to improve their own governance and transparency. We find that country characteristics explain much more of the variance in governance ratings (ranging from 39% to 73%) than observable firm characteristics (ranging from 4% to 22%). Further, we show that firm characteristics explain almost none of the variation in governance ratings in less-developed countries and that access to global capital markets sharpens firms’ incentives for better governance.

Abstract This paper investigates the effect of closed overnight exchanges on option prices. During the trading day, asset prices follow the literature's standard affine model that allows for stochastic volatility and random jumps. Independently, the overnight asset price process is modeled by a single jump. We find that the overnight component reduces the variation in the random jump process significantly. However, neither the random jumps nor the overnight jumps alone are able to empirically describe all features of option prices. We conclude that both random jumps during the day and overnight jumps are important in explaining option prices, where the latter account for about one quarter of total jump risk.

To identify the important tradeoffs in consulting a single expert for both diagnosis and treatment, we examine the costs and health outcomes of elderly Medicare beneficiaries with coronary artery disease. We compare the empirical consequences of diagnosis by cardiologists who can provide surgical treatment – “integrated” cardiologists – to the consequences of diagnosis by a nonintegrated cardiologist. Diagnosis by an integrated cardiologist leads, on net, to higher health spending but similar health outcomes. The net effect contains three components: reduced spending and improved outcomes from better allocation of patients to surgical treatment options; increased spending conditional on treatment option; and worse outcomes from poorer provision of nonsurgical care.

This paper analyzes the relationship between the diffusion of new technologies and the decentralization of firms. Centralized control relies on the information of the principal, which we equate with publicly available information. Decentralized control, on the other hand, delegates authority to a manager with superior information. However, the manager can use his informational advantage to make choices that are not in the best interest of the principal. As the available public information about the specific technology increases, the tradeoff shifts in favor of centralization. We show that firms closer to the technological frontier, firms in more heterogeneous environments, and younger firms are more likely to choose decentralization. Using three data sets on French and British firms in the 1990s, we report robust correlations consistent with these predictions.
