We suggest a simple asset market model in which we analyze competitive and strategic behaviornsimultaneously. If for competitive behavior two-fund separation holds across periods then itnalso holds for strategic behavior. In this case the relative prices of the assets do not dependnon whether agents behave strategically or competitively. Those agents acting strategically willnhowever...

A previous evaluation found a limited effect of a 4.4 percent reduction of the number of doctor visits in a sample of pharmacy customers. The re-evaluation based on a representative household survey, the German Socio-Economic Panel, yields a much larger effect. The paper uses this case study to discuss...

Co-Payments for Prescription Drugs and the Demand for Doctor Visits - Evidence from a Natural Experiment
The German health care reform of 1997 provides a natural experiment for evaluating the price sensitivity of demand for physicians’ services. As part of the reform, copayments for prescription drugs were increased by up to 200 percent. However, certain groups of people were exempted from the increase, providing a natural control group against which the changed demand for physicians’...

Training Intensity and First Labor Market Outcomes of Apprenticeship Graduates
The apprenticeship system is the most important source of formal post-secondary training in Germany. Using German register data - the IAB Employment Sample - we find that apprentices staying with their training firm after graduation have longer first-job durations but not higher wages than apprentices leaving the training firm. Retention rates, first job durations, and post-...

Downstream Investment in Oligopoly
We examine cost-reducing investment in vertically-related oligopolies, where firms may be vertically integrated or separated. Analyzing a standard linear Cournot model, we show that: (i) Integrated firms invest more than separated competitors. (ii) Vertical integration increases own investment and decreases competitor investment. (iii) Firms may integrate strategically so as to...

Multiple Unit Auctions and Short Squeezes
This article develops a theory of multiunit auctions where short squeezes can occur in the secondary market. Both uniform and discriminatory auctions are studied and bidders can submit multiple bids. We show that bidders with short and long preauction positions have different valuations in an otherwise common value setting. Discriminatory auctions lead to more short squeezing and...

Strategic Outsourcing Revisited
This paper analyzes a sequential game where firms decide about outsourcing the production of a non-specific input good to an imperfectly competitive input market. We apply the taxonomy of business strategies introduced by Fudenberg and Tirole (1984) to characterize the different equilibria. We find that outsourcing generally softens competition in the final product market. If firms...

Mobile Number Portability
This paper examines the consequences of introducing mobile number portability (MNP). As MNP allows consumers to keep their telephone number when switching providers, it reduces consumers’ switching costs. However, MNP may also cause consumer ignorance if telephone numbers no longer identify networks. As a result, while fostering competition for mobile customers, MNP may also induce...

Corporate Governance for Crooks? The Case for Corporate Virtue
Corporate scandals are reflected in excessive top management compensation and fraudulent accounts. These scandals cause an enormous amount of damage, not only to the companies affected, but also to the market economy as a whole. As a solution, conventional wisdom suggests more monitoring and sanctioning of management. We argue that these efforts will create a governance structure for...

Friedman Meets Hosios: Efficiency in Search Models of Money
In this paper we study the inefficiencies of the monetary equilibrium and optimal monetary policies in a search economy. We show that the same frictions that give fiat money a positive value generate an inefficient quantity of goods in each trade and an inefficient number of trades (or search decisions). The Friedman rule eliminates the first inefficiency and the Hosios rule the...
