Dual pricing is a vertical restraint whereby a manufacturer charges a distributor a different price for units intended to be resold online than for units intended to be resold offline. We study the competitive effects of dual pricing in a clearinghouse model, in which a manufacturer contracts with...

We examine the impact of agricultural productivity growth on deforestation in the tropics. We first develop a dynamic model of forest conversion to farmlands, in which conversion is costly and market potential for the agricultural output is limited - both of which affect the amount of land and...

We investigate whether the quality of investors’ information across horizons influences corporate investment. In our theory, managers under-invest because their stock price imperfectly reflects the value created by their projects. This effect is stronger when there is a mismatch between the horizon...

In supervised learning - for instance in image classification - modern massive datasets are commonly labeled by a crowd of workers. The obtained labels in this crowdsourcing setting are then aggregated for training. The aggregation step generally leverages a per-worker trust score. Yet, such worker...

Land market incompleteness is argued to have pervasive effects in Sub-Saharan Africa, including on agricultural efficiency, equity, and structural transformation. Yet experimental evidence on land market participation is virtually non-existent. We randomly allocate subsidies for agricultural...

Estimators of common parameters are often argued to be robust to random heterogeneity. One example of a situation in which such arguments have been made is when estimating structural breaks in panel data. In a seminal paper, Bai (Common Breaks in Means and Variances for Panel Data. Journal of...
