Bank market power shapes firm investment and financing dynamics and hence affects the transmission of macroeconomic shocks. Motivated by a secular increase in the concentration of the US banking industry, I study bank market power through the lens of a dynamic general equilibrium model with...

In this paper, we address the issue of the appropriate market structure in European mobile markets by presenting empirical evidence on the effect of the number of MNO on investment. Using a structural entry model based on a country-level dataset of 28 European countries, we find that, in average...

We examine the incentives and implications of supplier encroachment, when final good produc-tion requires the use of multiple complementary inputs and the entry of a supplier into the final good market gives rise to mutual outsourcing of inputs between the encroaching supplier and the incumbent....

This paper explores why competing firms can choose to outsource to an external common supplier that does not have a cost advantage in input production. The supplier, through its contract offers, manages to generate asymmetry, to alter product market competition, and to extract profits from the...

We broaden and develop the classic captive-and-shopper model of sales. Firstly, we allow for asymmetric marginal costs as well as asymmetric captive audiences. These asymmetries jointly determine the identities of the two or more firms we find compete (via randomized sales) to serve shoppers. In...

We present a general and tractable oligopoly model of multi-sided platforms with endogenous side and platform choices of heterogeneous end-users, considering any mix of single-homing and multi-homing platforms and in which participating on one side could preclude doing so on others. We show the...

We study changes in business dynamism in Europe after 2000 using novel microaggregated data that we collected for 19 European countries. In all countries, we document a broad-based decline in job reallocation rates that concerns most economic sectors and size classes. This decline is mainly...

With the advent of platform economies and the increasing availability of online price comparisons, many empirical markets now select on relative rather than absolute performance. This feature might give rise to the 'winner takes all/most' phenomenon, where tiny initial productivity differences...
