This paper shows that market concentration is positively related to outsourcing activities in a framework of Cournot competition with strategic outsourcing in a first stage. The theoretical priors are confirmed by rank correlation coefficients between the intermediate goods import intensity and...

More than 1.3 billion people lack access to electricity. The UN have proclaimed the goal of providing electricity to all by 2030. In recent years, Pico-Photovoltaic kits have become a lower cost alternative to investment intensive grid electrification. Using a randomized controlled trial we...

In a Cournot-oligopoly with free but costly entry and business stealing, output per firm is too low and the number of competitors excessive, assuming labor productivity to depend on the number of employees only or to be constant. However, a firm can raise the productivity of its workforce by...

Conjectural variation models are popular in empirical research as they infer the degree of market power from real data. IO-theorists, however disapprove it for lack of theoretical foundation arguing that dynamic reactions are forced into a static model with the strategy space and time horizon...

The paper investigates the determinants of banking profitability and banking market conditions in Austria. We conduct a panel econometric analysis which allows for testing the hypotheses which have become the most prominent in the literature on bank profitability: the...

We introduce a simple oligopolistic trade model with international transportation costs, and analyze the profitability and the social desirability of national vs. international mergers in relation to three different issues, (i) the level of trade freeness, (ii) the possibility of rent...

Imperfect competition in labor markets can lead to efficiency losses and lower aggregate output. In this paper, we study whether differences in competitiveness of labor markets can help explain differences in GDP per capita across countries. We structurally estimate a model of oligopsony with...

This paper presents an experiment on learning in repeated games, which complements the analysis of players' actual choices with data on the information acquisition process they follow. Subjects play a repeated Cournot oligopoly, with limited a priori information. The econometrics hinges on a...

What are the welfare implications of labor market power? We provide an answer to this question in two steps: (1) we develop a tractable quantitative, general equilibrium, oligopsony model of the labor market, (2) we estimate key parameters using within-firm-state, across-market differences in...
