Efficiency Gains and Mergers
In the theoretical literature, strong arguments have been provided in support of the efficiency defense in antitrust merger policy. One of the most often cited results is due to Williamson (1968) that shows how relatively small reduction in cost could offset the deadweight loss of a large price increase. Furthermore, Salant et al. (1983) demonstrate that (not for monopoly) mergers are unprofita...
متن کاملEfficiency gains from mergers
Efficiency Gains from Mergers by Lars-Hendrik Röller, Johan Stennek and Frank Verboven The purpose of this discussion paper is to contribute to the analysis of two questions. Should a merger control system take into account efficiency gains from horizontal mergers, and balance these gains against the anti-competitive effects of mergers? If so, how should a system be designed to account for effi...
متن کاملDoes Social Security Privatization Produce Efficiency Gains?
The economic literature shows that privatizing Social Security can improve labor supply incentives, but it can also reduce risk sharing when households face uninsurable risks. We simulate a stylized 50-percent privatization with transaction costs financed by consumption taxes and examined its impact on macroeconomic variables as well as on the welfare across generations and income classes. Our ...
متن کاملPartial-Order Planning: Evaluating Possible Efficiency Gains
Although most people believe that planners that delay step-ordering decisions as long as possible are more e cient than those that manipulate totally ordered sequences of actions, this intuition has received little formal justi cation or empirical validation. In this paper we do both, characterizing the types of domains that o er performance di erentiation and the features that distinguish the ...
متن کاملAssessing horizontal mergers under uncertain efficiency gains∗
The analysis of horizontal mergers hinges on a tradeoff between unilateral effects and efficiency gains. The article examines the role of uncertainty (on the efficiency gains) in this tradeoff. Common wisdom is that the antitrust authorities should be very cautious about random gains. Our results show that dismissing efficiency gains on the sole ground that they are uncertain would not be theor...
