A note on efficient simulation of multidimensional spatial autoregressive processes

In applications of spatial statistics, it is necessary to compute the product of some matrix W of spatial weights and a vector y of observations. The weighting matrix often needs to be adapted to the specific problems, such that the computation of Wy cannot necessarily be done with available R-packages. Hence, this article suggests one possibility treating such issues. The proposed technique avoids the computation of the matrix product by calculating each entry of Wy separately. Initially, a specific spatial autoregressive process is introduced. The performance of the proposed program is briefly compared to a basic program using the matrix multiplication.     

Emotional Climate in a European Problem Area: East Berlin and West Berlin Three Years After Reunification

In autumn of 1992, three years after the unification of Germany, during a period of violent attacks against foreigners, 120 students from East Berlin and West Berlin and 20 foreign students living in West Berlin answered the Emotional Climate Questionnaire developed by de Rivera and Fernandez-Dols. Foreign respondents expressed a positive attitude toward their government/state and believed in prosocial behavior to a greater extent than respondents from East Berlin and West Berlin. Whereas East Berlin students disagreed only somewhat with statements in favor of selfishness and egoism, West Berlin students strongly disagreed with them. We attribute the differences that were found in the answers of the foreign students to their national values. In addition, we regard the differences between the emotional climates of East Berlin and West Berlin as reflecting a climate of instability among East Berliners. We interpreted selfishness as a kind of polarized behavior indicating a climate of instability. A factor analysis revealed 5 factors of an emotional climate: Nation's Future, Just World, Reactive Egoism, Scepticism, and Basic Egoism. The concept of emotional climate is discussed on the basis of the current data.

THE SOLOW RESIDUAL FOR AUSTRALIA: TECHNOLOGY SHOCKS OR FACTOR UTILIZATION?

This paper presents evidence which implies that fluctuations in the Solow residual for Australia do not solely reflect technology shocks. Recent work suggests that the Solow residual is a noisy measure of technology shocks. One source of noise in the standard measure of the Solow residual is changes in factor utilization. In this paper a structural vector autoregression model for capacity utilization and the Solow residual is estimated. A transitory shock is identified that accounts, for about 30% of the short term variation in the Solow residual and virtually 100% of the variation in capacity utilization at all horizons.

Rational voters in a partisanship model

This paper examines a voter model for the US which is interconnected with the partisan theory. In our model, voters are rational and forward-looking. They are perfectly informed about the preferences of political parties and about the state of the economy. The predictions of our voter model differ from the predictions of conventional voter models, according to which the incumbent benefits from low unemployment and low inflation, irrespective of its political colour. In a partisan setting, the democratic party benefits from high unemployment and the republican party benefits from high inflation. Regressions of presidential approval rates indicate that the predictions of both the partisan voter model and the conventional model are consistent with the data.
