We present a model with firms selling (homogeneous) products in two imperfectly segmented markets (a "high-demand" and a "low-demand" market). Buyers are mobile but restricted by transportation costs, so that imperfect arbitrage occurs when prices differ in both markets. We show that equilibria are distorted away from Cournot outcomes to prevent consumer arbitrage. Furthermore, a merger can lead to ...
Horticulture has developed into one of the most dynamic agricultural sectors in the world. The cultivation of fruits and vegetables has significant potential for increasing agricultural income and reducing rural poverty, particularly in developing and emerging countries. However, it appears that the growing consolidation in the retail sector has shifted power relations along the value-added chain away ...
This paper uses the newly constructed Luxembourg Wealth Study data to document cross-country variation in homeownership rates and the homeownership-income inequality among young households in Finland, Germany, Italy, the UK and the US, and relate it to cross-country differences in mortgage market maturity. We find that aside from Italy, homeownership rates and inequality in the four countries correspond ...
Our paper deals with modeling the effects of introducing a market-based tool for improving end-users' efficiency in an energy market which is already regulated through a cap-and-trade system for green house gas emissions and a quota system meant to improve competitiveness of energy produced using renewable resources. Our results show that the regulation of energy demand achieves its underlying objects ...
We apply the EMF 23 study design to simulate the effects of the reference case and the scenarios to European natural gas supplies to 2025. We use GASMOD, a strategic severallayer model of European gas supply, consisting of upstream natural gas producers, traders in each consuming European country (or region), and final demand. Our model results suggest rather modest changes in the overall supply situation ...
In this study, we suggest an explanation for the alarmingly low growth rates of real housing prices in Canada and Germany in comparison to other OECD countries over 1975-2005. We show that the long-run development of housing markets is determined by real disposable per capita income, real long-term interest rate, population growth, and urbanization. The differential development of real housing prices ...
This paper analyzes the origins and welfare consequences of buyer power. We show that if suppliers are capacity constrained or have strictly convex costs, there are two different channels through which large buyers can obtain more favorable terms from their suppliers. In particular, we show how the presence of large buyers can then erode the value of suppliers' outside option. Somewhat surprisingly, ...
We consider a model with two firms operating their individual networks. Each firm can choose its price as well as its investment to build up its network. Assuming a skewed distribution of consumers, our model leads to an asymmetric market structure with one firm choosing higher investments. While access regulation imposed on the dominant firm leads to lower prices, positive welfare effects are diminished ...
