Abstract This paper analyses the income effect of the participation in elite sports using a unique dataset on former German top-level athletes. To quantify the average treatment effect we use covariate nearestneighbour matching. While our treatment group consists of formerly top-level athletes the control group of non-athletes is drawn from the GSOEP database. On average, former athletes receive higher incomes than similar non-athletes. Moreover, team sports athletes as well as male athletes realise significantly higher incomes. Comparing the income of former female athletes with male non-athletes, we find that participating in elite sports closes the gender-wage gap.

Abstract When Apple entered the ebook market, prices rose. A recent court decision found Apple guilty of colluding with publishers, blaming the price hike, in part, on agency agreements and prohibiting their use. Building a model to compare these with traditional wholesale agreements, we identify a single, pivotal condition that leads prices under agency to be higher than under wholesale with two-part tariffs but lower with linear pricing. Our model shows that the increase in ebook prices can be explained, instead, by heightened competition for reading devices, and it guides our understanding of when restricting agency agreements is advisable.

Terms of use: Documents in Acquisitions, Markups, Efficiency, and Product Quality: Evidence from India Joel Stiebale Dev Vencappa 1 October 2016 Abstract This paper uses a rich panel data set of Indian manufacturing firms to analyze the effects of domestic and international acquisitions on various outcomes at target firm and product level. We apply recent methodological advances in the estimation of production functions together with information on prices and quantities to estimate physical productivity, markups, marginal costs and proxies for product quality. Using a propensity score reweighting estimator, we find that acquisitions are associated with increases in quantities and markups and lower marginal costs on average. These changes are most pronounced if acquirers are located in technologically advanced countries. We also provide evidence that the quality of products increases while quality-adjusted prices fall upon acquisitions. JEL codes: F61, F23, G34, L25, D22, D24

Terms of use: Documents in Offshoring and Job Polarisation Between Firms * Hartmut Egger Udo Kreickemeier † University of Bayreuth TU Dresden CESifo, GEP, and IfW CESifo and GEP Christoph Moser Jens Wrona University of Salzburg University of Düsseldorf CESifo DICE November 2016 Abstract We set up a general equilibrium model, in which offshoring to a low-wage country can lead to job polarisation in the high-wage country. Job polarisation is the result of a reallocation of labour across firms that differ in productivity and pay wages that are positively linked to their profits by a rent-sharing mechanism. Offshoring involves fixed and task-specific variable costs, and as a consequence it is chosen only by the most productive firms, and only for those tasks with the lowest variable offshoring costs. A reduction in those variable costs increases offshoring at the intensive and at the extensive margin, with domestic employment shifted from the newly offshoring firms in the middle of the productivity distribution to firms at the tails of this distribution, paying either very low or very high wages. We also study how the reallocation of labour across firms affects economy-wide unemployment. Offshoring reduces unemployment when it is confined to high-productivity firms, while this outcome is not guaranteed when offshoring is also chosen by low-productivity firms.

Terms of use: Documents in Adjusting to Globalization -Evidence from Worker-Establishment Matches in Germany * Wolfgang Dauth University of Wuerzburg and IAB Sebastian Findeisen University of Mannheim and CEPR Jens Suedekum Duesseldorf Institute for Competition Economics (DICE) and CEPR January 2016 Abstract This paper addresses the impact of rising international trade exposure on individual earnings profiles in heterogeneous worker-establishment matches. We exploit rich panel data on job biographies of manufacturing workers in Germany, and apply a high-dimensional fixed effects approach to analyze endogenous mobility between plants, industries, and regions in response to trade shocks. Rising import penetration reduces earnings within job spells, and it induces workers to leave the exposed industries. Intra-industry mobility to other firms or regions are far less common adjustments. This induced industry mobility mitigates the adverse impacts of import shocks in the workers' subsequent careers, but their cumulated earnings over a longer time horizon are still negatively affected. By contrast, we find much less evidence for sorting into export-oriented industries, but the earnings gains mostly arise within job spells. These results point at an asymmetry in the individual labour market response to trade shocks: Import shocks trigger substantial "push effects", whereas the "pull effects" of export shocks are weaker.

Abstract We explore whether lawful cooperation in buyer groups facilitates collusion in the product market. Buyer groups purchase inputs more economically. In a repeated game, abandoning the buyer group altogether or excluding single firms constitute credible threats. Hence, in theory, buyer groups facilitate collusion. We run several experimental treatments using three-firm Cournot markets to test these predictions and other effects like how buyer groups affect outcomes when group members can communicate. The experimental results show that buyer groups lead to lower outputs when groups can exclude single firms. Communication is often abused for explicit agreements and this strongly reduces competition. JEL Classification: C7, C9, L4, L41

Abstract We analyze the welfare effects of structural remedies on merger activity in a Cournot oligopoly if the antitrust agency applies a consumer surplus standard. We derive conditions such that otherwise price-increasing mergers become externality-free by the use of remedial divestitures. In this case, the consumer surplus standard ensures that mergers are only implemented if they increase social welfare. If the merging parties can extract the entire surplus from the asset sale, then the socially optimal buyer will be selected under a consumer standard. JEL-Classification: L13, L41, K21
