Assuming deterministic demand Liski and Montero (2006) show that forward trading is able to facilitate collusion. We present a more concise model incorporating the main reason for forward trading: Uncertainty. In general, fl uctuations make collusion harder to sustain (Rotemberg and Saloner,...

The study analyzes the impact of European antitrust enforcement on industry performance measured as competition intensity (Price Cost Margin) and productivity (labor productivity and distance to the frontier). For a panel of OECD countries on the industry level since 1988, we estimate the impact...

We investigate how remedies in merger control affect information acquisition by an antitrust agency. We identify conditions under which an ''extreme options'' regime which does not allow for remedies improves information acquisition by the agency which increases consumer surplus. The legislator...

We evaluate the impact of competition on investments in Europe's mobile communications market during the 2011-2021 period. There are stark and sustained differences in market outcomes between three- and four-player markets in Europe, and economic theory suggests these could be partly explained...

This paper studies the effects of infrastructure sharing agreements on telecommunications markets. Using a model with an investment stage where firms compete" 'a la Cournot", I find that, infrastructure sharing agreements increase investment at industry level. Indeed, the sharing of...

This papers analyses price collusion between platforms in a two-sided market model based on Armstrong (2006). In particular, it addresses Evans and Schmalensee's hypothesis of collusion being harder to sustain because of feedback effects and stronger requirements concerning agreements and...

In this paper, we compare the distribution of price changes between collusive and non-collusive periods for ten major cartels. The first moments focus on previous research. We extend the discussion to the third (skewness) and fourth (kurtosis) moments. However, none of the above descriptive...

Given various recent antitrust investigations on the retail sector, we deal with uncovering demand systems substitution patterns for a particular market (diapers) to investigate the inter-format competition (supermarkets vs. discounters vs. drugstores). Using the uncovered demand system we...

We estimate the spillovers on firm profitability and market shares in oligopolistic markets through the transition from an n to an n-1 player oligopoly after a merger in the industry. Competitors are identified via the European Commission s market investigations and our methodology allows us to...
