We study changes in markups across 72 product markets from 2006 to 2018. A growing literature has documented a rise in markups over time using a production function approach; we instead employ the standard microeconomic method, which is to estimate demand and then invert firms' first-order...

We introduce and analyze a new market design for trading financial assets. The design allows traders to directly trade any user-defined linear combination of assets. Orders for such portfolios are expressed as downward-sloping piecewise-linear demand curves with quantities as flows...

Is shareholder interest in corporate social responsibility driven by pecuniary motives (abnormal rates of return) or non-pecuniary ones (willingness to sacrifice returns to address various firm externalities)? To answer this question, we categorize the literature into seven tests: (1) costs of...

We formulate a quantitative dynamic equilibrium theory of trade in the fed funds market, calibrate it to fit a comprehensive set of marketwide and micro-level cross-sectional observations, and use it to make two contributions to the operational side of monetary policy implementation. First, we...

Studies of intermediated arbitrage argue that bank balance sheets are an important consideration, yet little evidence exists on banks' positioning in this context. Using confidential supervisory data (covering $25 trillion in daily notional exposures) we examine banks' positions in connection...

We study the effect of price caps on the provision of costly effort by pharmaceutical firms using variation in drug discounts generated by a price regulation program that allows eligible hospitals to purchase outpatient drugs at steep discounts. These discounts directly affect drug...

Across many sectors, research has established that management explains a notable portion of productivity differences across organizations. A remaining question, however, is whether it is managers themselves or firm-wide management practices that matter. We shed light on this question by...

We study direct productivity changes and spillovers after a randomized training program for the frontline workers in a Colombian government agency. While trained workers improved their individual production, we also find substantial spillovers that affected managers' productivity. We use email...

The potential of artificial intelligence (AI) to simplify existing healthcare processes and create new, more efficient ones is a major topic of discussion in the industry. Yet healthcare lags other industries in AI adoption. In this paper, we estimate that wider adoption of AI could lead to...

We critically review the emerging literature in Organizational and Personnel Economics concerning the role of managers and management practices. Our focus is on the middle managers who populate the hierarchies between top executives and front-line employees. We are especially concerned with...
