The South African liquid fuels industry is a significant part of the economy. Historically, government policy focused on import substitution industrialization to support industry margins. This approach is called into question by the 2006 shift from net exports to imports and by inflated...

Die Worte Wettbewerb und Gemeinwohl kommen im Grundgesetz nicht vor. In ständiger Rechtsprechung betont das Bundesverfassungsgericht, dass das Grundgesetz keine Entscheidung über die deutsche Wirtschaftsverfassung getroffen hat. Gleichwohl hat das Gericht häufig über das Verhältnis von...

Firms often set long notice periods when consumers cancel a contract, and sometimes do so even when the costs of changing or canceling the contract are small. We investigate a model in which a firm offers a contract to consumers who may procrastinate canceling it due to naive present-bias. We...

We analyze the equilibrium effects of different subsidies on target goods under both perfectly competitive and monopolistic market structures. We concentrate our analysis on three particularly common forms of subsidies: (i) a per-unit subsidy, (ii) an ad valorem subsidy, and (iii) an "inversely...

In this paper we investigate how heterogeneous agents choose among tournaments with different prizes. We show that if the number of agents is sufficiently small, multiple equilibria can arise. Depending on how the prize money is split over the tournaments, these may include, for example, a...

Armed conflicts, natural disasters and infrastructure projects continue to force millions into migration. This is especially true for developing countries. After World War II, about 8 million ethnic Germans experienced a similar situation when forced to leave their homelands and settle within...

In his paper I study policy responses to an increase in post-merger distress. I consider the integration of regions as a merger of populations which I view as a revision of social space, and I identify the effect of the merger on aggregate distress. The paper is based on the premise that the...
