This study evaluates the impact of competition on quality, innovation and price in Europe's mobile communications market during the 4G era (2011-18). Our results indicate that European mobile users in more concentrated markets benefitted the most from higher network quality, particularly with...

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...

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 present results from a market experiment where firms with identical products can choose not only their price but also the format of their product. Products with different formats are difficult to compare but products with the same format are directly comparable. Savvy consumers buy the lowest...

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...

Patent settlements in the pharmaceutical industry between originator and generic firms have been scrutinized critically by competition authorities for delaying the market entry of generics and being therefore potentially anticompetitive. In this paper we present a model that analyzes the...

An astonishing 33 % of all export spells in Danish data turn out to be isolated single-month one-off export transactions. On average, for an export-active firm, one-off events generate 17 % of foreign sales. These patterns do not sit well with available trade models. To reconcile theory with the...

Credence goods markets, such as those for car repairs and medical treatments, are generally characterized by an ex-ante and ex-post information asymmetry between the uninformed buyer and the informed seller. Previous literature demonstrates that efficiency and fraud in a monopolist credence...

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,...
