Monetary Policies in the Presence of Asymmetries

JCMS: JOURNAL OF COMMON MARKET STUDIES, Issue 4 2000
Paul De Grauwe
In this article we study the theory of monetary policy when the monetary authority faces asymmetries in the countries constituting the monetary union. We identify two asymmetries (shocks and transmission) in the context of a two-country model. A general finding is that, as the degree of asymmetries increases, the effectiveness of stabilization of output and unemployment is reduced. As a result, when asymmetries increase, the stabilization effort of the central bank declines for given preferences about stabilization. We also find that the central bank can improve the efficiency of its monetary policies when asymmetries in the transmission exist, by using national information in the setting of optimal policies. The declared strategy of the ECB conflicts with this prescription. However, in practice the ECB is likely to follow this prescription. [source]

Spatial duopoly with triangular markets*

PAPERS IN REGIONAL SCIENCE, Issue 1 2005

Hotelling model; triangular market; duopoly Abstract., This article develops a duopoly model in which consumers are uniformly distributed along three sides (streets) of a triangular park and each consumer walks across the park in the shortest way to the lowest-price firm to buy one unit of a product. Two important findings emerge from our analysis. First, both firms choose location adjustment rather than price-cutting as a competition strategy to pursue their maximum profit. Second, asymmetric triangular markets provide more advantage to the firms than do symmetric ones. The intuition of this result is that each firm's monopoly power increases as the degree of asymmetry increases; firms can therefore raise their product prices in order to increase their profit.

Conductance asymmetry of a slot gate Si-MOSFET in a strong parallel magnetic field

ANNALEN DER PHYSIK, Issue 12 2009
I. Shlimak
Abstract We report measurements on a Si-MOSFET sample with a slot in the upper gate, allowing for different electron densities n1,2 across the slot. The dynamic longitudinal resistance was measured by the standard lock-in technique, while maintaining a large DC current through the source-drain channel. We find that the conductance of the sample in a strong parallel magnetic field is asymmetric with respect to the DC current direction. This asymmetry increases with magnetic field. The results are interpreted in terms of electron spin accumulation or depletion near the slot. [source]

ASYMMETRIC MULTIPRODUCT FIRMS, PROFITABILITY AND WELFARE

BULLETIN OF ECONOMIC RESEARCH, Issue 2 2009
George Symeonidis
L13; D43 ABSTRACT In a differentiated multiproduct Cournot duopoly with linear demand, industry profit usually falls (even though concentration rises) when the distribution of products across firms becomes more asymmetric, if the products are not very differentiated or the total number of products is large. Consumer surplus and overall welfare always fall as the degree of asymmetry increases. These results contrast with the conventional wisdom on the effects of firm heterogeneity and the links between concentration and industry profits. [source]
