Maximizing votes under imperfect information

This paper presents an alternative, sympathy voting, to the usual public choice approaches. It deals with voters whose decision depends both on an economic component and a sympathy component. The politician is perfectly informed of the economic component, but not of the sympathy component. The paper compares vote maximization under sympathy voting to the maximization of votes which come from pure homines oeconomici. Sympathy voting is defined in such a way that pure economic voting is its limiting case. The latter property can be used to apply the classical Lagrangean technique to maximizing votes under economic voting. The approach is applied to two typical examples of political choice: the property tax/local public expenditure decision, and public pricing of local public utilities.     

The impact of macroeconomic news on quote adjustments, noise, and informational volatility

We study the impact of the arrival of macroeconomic news on the informational and noise-driven components in high-frequency quote processes and their conditional variances. We decompose bid and ask returns into a common (“efficient return”) factor and two market-side-specific components capturing market microstructure effects. The corresponding variance components reflect information-driven and noise-induced volatilities. We find that all volatility components reveal distinct dynamics and are positively influenced by news. The proportion of noise-induced variances is highest before announcements and significantly declines thereafter. Moreover, news-affected responses in all volatility components are influenced by order flow imbalances.     

The Impact of European Integration and German Unification on Industrial Relations in Germany

Can the present turmoil in German industrial relations be attributed to the effects of the Single Market, or to unification, or to other factors? European regulation or legislation may intervene in the German industrial relations system, may remove responsibilities from national actors, or may, by deregulation, induce stronger interdependence between national regimes. Various instances are considered to evaluate the actual and potential EU impact on German industrial relations. The evidence suggests that fears of ‘social dumping’ in the richer member-states are largely unfounded, and that the effects of unification and the recession on German industrial relations are currently more significant than the impact of European integration.     

How do commodity futures respond to macroeconomic news?

This paper investigates the impact of seventeen US macroeconomic announcements on two broad and representative commodity futures indices. Based on a large sample from 1989 to 2005, we show that the daily price response of the CRB and GSCI commodity futures indices to macroeconomic news is state-dependent. During recessions, news about higher (lower) inflation and real activity lead to positive (negative) adjustments of commodity futures prices. In contrast, we find no significant reactions during economic expansions. We attribute this asymmetric response to the state-dependent interpretation of macroeconomic news. Our findings are robust to several alternative business cycle definitions.

The Catching-up of Japanese with German Industries: Production Organization, Infrastructure, and R&D

This paper presents an empirical productivity comparison between Japan and Germany, focusing on organization, R&D and infrastructure. Time-series datasets from the auto vehicle and electronic engineering industries are used to demonstrate the reversal in productivity advantage from Germany to Japan at around 1980. It is argued that Japanese productivity gains arose from a better infrastructure and from cost-reducing innovations such as lean production methods. An econometric model determines the causes for the observed differences in the quantities of inputs used. It shows that frequent external procurement in Japanese manufacturing has shifted the factor inputs from labor and capital to materials, a result in line with the philosophy of lean production.
