Performance-raising practices tend to diffuse slowly in the health care sector. To understand how incentives drive adoption, I study a practice that generates revenue for hospitals: submitting detailed documentation about patients. After a 2008 reform, hospitals could raise their Medicare...

In official international trade statistics, annual commerce between every pair of countries is reported twice: once by the importing country and once by the exporter. These double reports provide an opportunity for audit. In principle, the two reported trade values should differ systematically...

Private equity funds hold assets that are hard to value. Managers may have an incentive to distort reported valuations if these are used by investors to decide on commitments to subsequent funds managed by the same firm. Using a large dataset of buyout and venture funds, we test for the presence...

We test and compare the effects of introduction of two new financial information technologies, EDGAR and XBRL, on well-known asset pricing anomalies often attributed to mispricing. EDGAR facilitates easier access to public accounting information about public firms; XBRL reduces the cost of...

In this paper I argue that corporate finance theory, empirical research, practical applications, and policy recommendations are deeply rooted in an underlying theory of the firm. I also argue that while the existing theories have delivered very important and useful insights, they seem to be...

We investigate how the contractibility of actions affecting the value of an asset affects asset ownership. We examine this by testing how on-board computer (OBC) adoption affects truck ownership. We develop and test the proposition that adoption should lead to less ownership by drivers,...

Both managerial ownership and performance are endogenously determined by exogenous (and only partly observed) changes in the firm's contracting environment. We extend the cross-sectional results of Demsetz and Lehn (1985) and use panel data to show that managerial ownership is explained by key...

Recent research has documented large differences between countries in ownership concentration in publicly traded firms, in the breadth and depth of capital markets, in dividend policies, and in the access of firms to external finance. We suggest that there is a common element to the explanations...

We present a model of the effects of legal protection of minority shareholders and of cash flow ownership by a controlling shareholder on the valuation of firms. We then test this model using a sample of 371 large firms from 27 wealthy economies. Consistent with the model, we find evidence of...

This paper investigates what factors determine whether a commercial banker is on the board of a non-financial firm. We consider the tradeoff between the benefits of direct bank monitoring to the firm and the costs of active bank involvement in firm management. Given the different payoff...
