In a standard dynamic stochastic general equilibrium framework, with sticky prices, the cross sectional distribution of output and inflation across a population of firms is studied. The only form of heterogeneity is confined to the probability that the ith changes its prices in response to a shock. In this Calvo setup the moments of the cross sectional distribution of output and inflation depend crucially ...
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 ...
In this paper, we discuss potential developments of the world natural gas industry at the horizon of 2030. We use the World Gas Model (WGM), a dynamic, strategic representation of world natural gas production, trade, and consumption between 2005 and 2030. We specify a "base case" which defines the business-as-usual assumptions based on forecasts of the world energy markets. We then analyze the sensitivity ...
Die aktuellen Finanzmarktturbulenzen wurden durch Entwicklungen im Immobiliensektor ausgelöst. Vor diesem Hintergrund analysiert dieser Beitrag den Zusammenhang zwischen den Immobilienpreisen und der Geldmengen- und Kreditvolumensentwicklung für den Zeitraum 1992 -2006 (westdeutsche Preisdaten) bzw. 1997 bis 2006 (ostdeutsche Preisdaten). Die Untersuchung konzentriert sich erstmals auf die Bundesrepublik ...
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 ...
Die Transmission monetärer Impulse auf zunehmend integrierten Finanzmärkten ist von herausragender Bedeutung für die Zentralbanken. Falls die starke Ausweitung der Liquidität in den letzten Jahren zu den Preisübertreibungen an den Finanzmärkten beigetragen hat, könnte die Einbeziehung von Vermögenspreisen in die geldpolitische Reaktionsfunktion dazu beitragen, potenzielle negative Konsequenzen für ...
