Middlemen are ubiquitous in supply chains. In developing countries they help bring products from remote communities to end markets but may exert strong market power. We study a cooperative intervention which organizes together poor fishing communities in the Amazon -- one of the poorest and most...

Using Visa debit and credit card transactions in the U.S. from 2016 to 2019, we document the importance of customers in accounting for sales variation across merchants, across stores within retail chains, and over time for individual merchants and stores. Customers, as opposed to transactions...

Although typically overlooked, many purchase datasets exhibit a high incidence of products with zero sales. We propose a new estimator for the Random-Coefficients Logit demand system for purchase datasets with zero-valued market shares. The identification of the demand parameters is based on a...

COVID-19 led to a massive shutdown of businesses in the second quarter of 2020. Estimates from the CPS, for example, indicate that the number of active business owners dropped by 22 percent from February to April 2020. In this descriptive research note, we provide the first analysis of losses in...

The level of diseconomies of scale in asset management has important implications for tests of manager skill and the expected level of performance persistence. To identify the causal impact of fund size on future returns, we exploit the fact that small differences in returns can cause discrete...

Alternatives to the current system of separate tax accounting, such as the proposed Common Consolidated Corporate Tax Base in Europe, would apportion a firm's worldwide profits using formulas based on the location of employment, capital or sales. This paper offers a new method of evaluating the...

This paper uses data from NBER surveys of over 40,000 employees in hundreds of facilities in 14 firms and from employees on the 2002 and 2006 General Social Surveys to explore how shared compensation affects turnover, absenteeism, loyalty, worker effort, and other outcomes affecting workplace...

We investigate how the employment-based health insurance system in the U.S. affects individuals' life-cycle health-care decisions. We take the viewpoint that health is a form of human capital that affects workers' productivities on the job, and derive implications of employees' turnover on the...

This paper documents the diverging trends in volatility of the growth rate of sales at the aggregate and firm level. We establish that the upward trend in micro volatility is not simply driven by a compositional bias in the sample studied. We argue that this new fact sheds some shadows on the...

Recording industry revenue has fallen sharply in the last three years, and some -- but not all -- observers attribute this to file sharing. We collect new data on albums obtained via purchase and downloading, as well as the consumers' valuations of these albums, among a sample of US college...
