This paper examines how horizontal mergers affect firms’ incentives to invest in R&D leading to the development of new products. We characterize the impact of a merger to monopoly and a 3-to-2 merger on equilibrium innovation efforts and consumer surplus, absent efficiency gains and spillovers...

To build inputs for end-to-end machine learning estimates of the causal impacts of law, we consider the problem of automatically classifying cases by their policy impact. We propose and implement a semi-supervised multi-class learning model, with the training set being a hand-coded dataset of...

To what extent do car buyers undervalue future fuel costs, and what does this imply for tax policy? To address both questions, we show it is crucial to account for consumer mileage heterogeneity. We use product-level data for a panel of European countries and exploit fuel cost variation by engine....

In terms of sustainability, the effects of the development of organic farming are subject to debate, particularly regarding the methods used to compare organic and conventional food systems and the consequences of the conventionalization of organic farming. We propose an empirical study centered on...

This paper analyzes a supplier's incentives to foreclose downstream entry when entrants have stronger positions in different market segments, thus bringing added value as well as competition. We first consider the case where wholesale contracts take the form of linear tariffs, and characterize the...
