This thesis contains four essays which are all from the broader field of insurance economics. The chapters can be read independently, although there is a certain connection between the articles. Chapter 2, which deals with moral hazard, and chapter 3, which is on oligopolistic models in the...

The aim of this work is to establish a mathematically precise framework for studying games of capital accumulation under uncertainty. Such games arise as a natural extension from different perspectives that all lead to singular control exercised by the agents, which induces some essential...

This dissertation examines two problems that may arise in matching problems.The first two chapters deal with auctions for multiple units where bidders exhibitexternalities. The third chapter links risk aversion and information to unraveling inlabor markets.Auctions can lead to efficient...

Since Hotelling's (1929) seminal work, economists have tried to understand how product differentiation affects price competition. I study the product location decisions, on a vertical characteristic space, of two sets of horizontal competitors when the inputs supplied by the "upstream" set (the...

In this paper we develop a spatial Cournot trade model with two unequally sized countries, using the geographical interpretation of the Hotelling line. We analyze the trade and welfare effects of international trade between these two countries. The welfare analysis indicates that in this...

In this paper we develop a theoretical model of competition among marketing cooperatives (co-ops) in a spatial market setting assuming uniform delivered pricing and Löschian conduct. The model is an extension to Alvarez et al.’s (2000) spatial competition model for investorowned firms (IOF)....

This paper extends the interval Hotelling model with quadratic transport costs to the n−player case. For a large set of locations including potential equilibrium configurations, we show for n 2 that firms neither maximize differentiation - as in the duopoly model - nor minimize...

We use a spatial competition based model in a two-stage game setup to assess whether equilibrium in exchange rates among the leading currencies is attainable. We show that a stable equilibrium can be reached in the case of two leading currencies, but not in the case of three. In our model,...

Agricultural markets often feature significant transport costs and spatially distributed production and processing which causes spatial imperfect competition. Spatial economics considers the firms’ decisions regarding location and spatial price strategy separately, usually on the demand side,...
