Using a sample of long-term supply contracts collected from SEC filings, I show that hold-up concerns and information asymmetry are important determinants of contract design. Asymmetric information between buyers and suppliers leads to shorter term contracts. However, when longer duration contracts facilitate the exchange of relationship specific assets, the parties substitute short-term contracts with financial covenants in order to reduce moral hazard. Covenant restrictions are more prevalent when direct monitoring is costly and the products exchanged are highly specific. Finally, I find that buyers and suppliers are less likely to rely on financial covenants when financial statement reliability is low.

This study examines the strategic use of corporate philanthropy programs to achieve financial reporting objectives. Corporate-sponsored foundations allow managers to maintain stable levels of giving to charitable causes while providing substantial discretion as to the amount of contribution expense recorded on the income statement in any given period. I find that firms reporting small earnings increases make income-increasing discretionary foundation funding choices. This result is associated with firms that have strong equity market incentives to manage earnings. The evidence presented in this paper is consistent with firms using their charitable foundations as off-balance sheet reserves.

Increased awareness of the importance of non-bank financial infrastructures has brought increased concern about the potential for bailouts and the resultant moral hazard problem. This paper examines the question with regard to derivatives central counterparties. We consider the layers of protection that derivatives central clearing parties (CCPs) have established in the absence of an expectation of regulatory rescue. We then provide a model of the tension between the desire for ex post rescue of a systemically important financial infrastructure and the desire to maintain ex ante discipline on the infrastructure. The model illustrates the factors that should lead to relaxation or tightening of the financial regulator's discretion for rescue. We consider examples of failures of derivatives CCPs in order to highlight the importance of these considerations.

Dealers enter nonbinding expressions of interest during the Nasdaq preopening to promote price discovery and ease stock inventory management when the market opens. But does this practice of “indicating ahead” constitute best execution for an individual customer? Arguments in favor of the practice rely on the notion that best execution is a general condition as opposed to a concept applicable on a trade-by-trade basis. Some customers must sacrifice in individual instances to improve the functioning of the overall market. But the practice of indicating ahead violates the dealer agent's duty of loyalty to her individual customer. Moreover, the dealer's financial self-interest is best served by indicating ahead.

The standard Principal–Agent (PA) model assumes that the principal can control the agent's consumption profile. In an intertemporal setting, however, Rogerson (1985, Econometrica53, 69–76) shows that given the optimal PA contract, the agent has an unmet precautionary demand for savings. Thus the standard PA model is invalid if the agent has access to credit markets. In this paper we generalize the standard PA model to allow for saving and borrowing by the agent. We show that the impact of such access critically depends upon the treatment of default. If default is not permitted, efficiency is strictly reduced by the introduction of credit markets, and the equilibrium level of borrowing or saving is indeterminate in the model. If default is allowed, however, the optimal contract depends upon the level of bankruptcy protection in the economy, which is described by a minimum level of wage income. We show that there is an optimal intermediate range of bankruptcy protection. Within this range, allowing default increases efficiency in the economy relative to the case of no default. Also, the model predicts specific levels of consumer debt, interest rates, and default rates as functions of the level of bankruptcy protection level.

We examine the relation between venture capital (VC) investments, M&A activity, and merger competition laws in 45 countries around the world. We find evidence of a strong positive association between VC investments and lagged M&A activity, consistent with an active M&A market providing viable exit opportunities for VC companies and therefore incentives for venture capitalists to invest. We also explore the effects of country-level merger competition laws and pro-takeover legislation passed internationally on VC activity. We find significant reductions in VC activity in countries with stricter competition laws and find that VC activity intensifies after the enactment of country-level takeover-friendly legislation.

Studies proposing new determinants of corporate innovation include previously identified factors in an ad hoc manner. We find that only a sparse set of recently proposed innovation determinants provide material, independent information about patents and citations. We document that inferences in recent empirical studies often change when we include previously discovered innovation determinants. Commonly used econometric methods, including fixed effects and plausible shocks, do not always mitigate the need to condition on previously identified innovation determinants. Rather than randomly selecting a subset of control variables from prior studies, our analysis offers researchers a framework to consider previously proposed variables. (JEL G30, O30, G32, O34).

We distinguish between identification and establishing causality. Identification means forming a unique mapping from features of data to quantities that are of interest to economists. Establishing causality by finding sources of exogenous variation is often considered synonymous with identification, but these two concepts are distinct. Exogenous variation is only sometimes necessary and never sufficient to identify economically interesting parameters. Instead, even for causal questions, identification must rest on an underlying economic model. We illustrate these points by analyzing identification in three recent papers and by examining the estimation of a simple dynamic model.

We examine the empirical implications of learning under ambiguity for the cross-section of stock returns. We introduce a theoretically-motivated ambiguity measure and find that ambiguity is priced in the cross-section of average stock returns. Ambiguity is not subsumed by state variables known to predict stock returns, nor by value, size, and momentum factors. In R-squared comparative tests, a model that takes ambiguity into account performs better than empirical implementations of the Bayesian learning model, the intertemporal CAPM, and the four-factor model of Fama and French (1993) and Carhart (1997).
