We study the profitability of bundling by an upstream firm who licenses com-plementary technologies to downstream competitors, and who faces a superior competitor for one of its technologies. In an otherwise standard “Chicago-style” model, we show that the existence of downstream competition can...

Does enhanced access to data foster or hinder competition among firms? Using a competition-in-utility framework that encompasses many situations where firms use data, we model data as a revenue-shifter and identify two opposite effects: a mark-up effect according to which data induces firms to...

We evaluate the geographical misallocation of solar photovoltaic installations and their relation with the uniform nature of subsidies. We estimate...

In this paper, we investigate a continuous time version of the Stochastic Langevin Monte Carlo method, introduced in [39], that incorporates a stochastic sampling step inside the traditional overdamped Langevin diffusion. This method is popular in machine learning for sampling posterior...

Psychological traits display substantial variation worldwide.

Most low- and middle-income countries are characterised by a large informal sector, which implies that a substantial fraction of economic activity in these countries is completely unregulated. This has important implications for the behaviour of firms, workers, families, and consumers, with these...
