This article provides a methodological and empirical approach for assessing price level convergence and its relation to purchasing power parity (PPP) using annual price data for seventeen U.S. cities during the period 1918 to 2005. We suggest a new panel data procedure that can handle a wide...

This paper assesses empirically two competing unemployment theories. It identifies one structural break in U.K. and German unemployment around 1980 that is more severe in both absolute and relative terms than that for the United States in 1973. This offers support for the structuralist theory. A...

Summary Following the influential work of Nelson and Plosser (1982) stochastic trends in macroeconomic time series are considered to be a stylized fact. However, since the stochastic trend hypothesis can be rejected for many economic series if a segmented trend model is considered as an...

Summary Starting from today’s definition of innovation indicators, this paper analyses the dynamic relationships between innovation activities (approximated by two innovation input indicators and one innovation output indicator) and per capita income in Germany for the two periods from 1850...

Summary We analyse German public finances against a theoretical background using a unique database, retrieved from multiple sources covering the period between 1850 and 2010.Multiple currency crises and force majeure offer anecdotal evidence contradicting the historical perception of Germany...

Autism spectrum disorders are connected with disturbances of neural connectivity. Functional connectivity is typically examined during a cognitive task, but also exists in the absence of a task i.e., “rest.” Adults with ASD have been found to show weaker connectivity relative to controls....

Linear asset-pricing relations, with macroeconomic factors as state variables, have found wide usein empirical finance. Applications of such relations range from academic studies of market efficiency andmarket anomalies to practical uses such as risk management and estimation of the cost of...

The size and power of the Wald, Edgeworth expansion corrected likelihood-ratio statistic (LRE), and bootstrap tests for Granger causality in integrated-cointegrated VAR systems are considered. By using Monte Carlo methods and simple graphical techniques, the p-value plots, and power-size plots,...

Summary Interpreting Granger causality as economic causality implies that the underlying VAR model is a structural economic model. This is wrong in the case of simultaneity, and causal conclusions can be misleading. Nevertheless, the empirical relevance of this problem still needs to be...
