Incorporating weakly nonseparable preferences into the familiar time-preference model, we emphasize a role of steady-state welfare changes in determining the effect of permanent tariffs on the current account. The effect consists of: a welfare effect, due to steady-state welfare changes, which...

It is often argued, though mostly informally, that outward foreign direct investment (FDI) is a synonym for the export of employment and thus detrimental to the home economy. To see whether and under what conditions this intuition indeed holds true, we construct a model of unionized duopoly and...

We investigate the effects of restricting locations of firms into Hotelling duopoly models. In the standard location-price models, the equilibrium distance between firms is too large from the viewpoint of consumer welfare. Thus, restricting locations of firms and reducing the distance between...

This paper develops an overlapping-generations model with nominal wage rigidities and examines the welfare effects of debt policy when unemployment exists. Issues of public debt stimulate aggregate consumption demand and create employment. Future generations then face both increased wage incomes...

This paper provides a welfare comparison of a tariff with a combination of a production subsidy to, and a commodity tax on, an import-competing commodity in a two-country economy. We treat some plausible situations of industry protection, including where the initial tariff is above the optimal...

We investigate a multi-market Cournot model with strategic process R&D investments wherein a multi-market monopolist meets entrants that enter one of the markets. We find that entry can enhance the total R&D expenditure of the incumbent firm. That is, entry can stimulate R&D effort. Moreover,...

Die anhaltend hohe Arbeitslosigkeit hat verstärkt zu Diskussionen geführt, ob das Steuer-Transfer-System hierfür mitverantwortlich sei. Dabei wurde insbesondere auf die sehr hohe implizite Grenzbelastung im untersten Einkommensbereich hingewiesen. Als Alternativen wurden eine negative...

This paper examines how the option of a regulated linear input price affects vertical contracting, where a monopolistic upstream supplier sequentially offers supply contracts to two symmetric downstream firms. We find that equilibrium contracts vary with production cost and regulated price...

Certifiers contribute to the sound functioning of markets by reducing a symmetric information. They, however, have been heavily criticized during the 2008-09 financial crisis. This paper investigates on which side of the market a monopolistic profit-maximizing certifier offers his service. If...

Die hier vorgestellten Überlegungen nehmen direkt Bezug auf die im Zuge der projektinternen Synopse identifizierten Unzulänglichkeiten aktuell diskutierter Wohlfahrts- und "grüner" Wachstumskonzepte in ihrem Verhältnis zu dem bislang in der Bundesrepublik Deutschland etablierten...
