We explore the managerial implications and economic consequences of platform sharing under models of horizontal and vertical product differentiation. By using a common platform across different products, firms can save on fixed costs for platform development. At the same time, platform sharing...

Contractual theories of vertical integration derive firm boundaries as an efficient response to market transaction costs. These theories predict a relationship between underlying features of transactions and observed integration decisions. There has been some progress in testing these...

We develop a new theory of the firm where asset owners sometimes want to change partners ex-post. The model identifies a fundamental trade-off between (i) a "displacement externality" under non-integration, where a partner leaves a relationship even though the benefit is worth less than the loss...

We take a first look at financial patents at the European Patent Office (EPO). As is the case at the US Patent and Trademark Office (USPTO), the number of financial patents in Europe has increased significantly in parallel with significant changes in payment and financial systems. Scholars have...

We compare sources of funds and investment activities of venture capital (VC) funds in Germany, Israel, Japan and the UK using a newly constructed data set. The data provide a rare opportunity to evaluate relations between funds' sources of finance and activities. We find that sources of VC...

Agents with more experience make better choices. We measure learning dynamics using a panel with four million monthly credit card statements. We study add-on fees, specifically cash advance, late payment, and overlimit fees. New credit card accounts generate fee payments of $15 per month....

The distance between small firms and their lenders in the United States is increasing. Not only are firms choosing more distant lenders, they are also communicating with them in more impersonal ways. After documenting these systematic changes, we demonstrate that they do not stem from small...

We find that institutional ownership in publicly traded companies is associated with more innovation (measured by cite-weighted patents). To explore the mechanism through which this link arises, we build a model that nests the lazy-manager hypothesis with career-concerns, where institutional...

This paper builds on Froot and Stein (1998) in developing a framework for analyzing the risk allocation, capital budgeting, and capital structure decisions facing insurers and reinsurers. The model incorporates three key features: i) value-maximizing insurers and reinsurers face product-market...

This paper studies the information content and consequences of third-party voting advice issued during proxy contests. We document significant abnormal stock returns around proxy vote recommendations and develop an estimation procedure for disentangling stock price effects due to changes in...
