Economic phenomena are interrelated. From a growth perspective, time analysis concerning the choices of present and future consumption and the choices between the allocation of scientific resources should be combined with a space analysis regarding the dissemination of economic activity through...

The city size distribution of many countries is remarkably well approximated by a Pareto distribution. We study what constraints this regularity imposes on standard urban models. We find that under general conditions urban models must have (i) a balanced growth path and (ii) a Pareto...

This paper presents an empirical study of GDP per worker (and per capita) convergence across German labour market regions during 1992 to 2002 using nonparametric techniques. There is evidence for a tendency towards convergence during the observed period, i.e. regions that were less productive in...

"The paper analyses movements in the unemployment rate of West German districts in the period 1992-2004 by the chain reaction theory of unemployment (CRT). The estimations show that unemployment movements are generated together by lagged adjustment processes and by exogenous shocks. We find that...

"Theories in regional science predict that related establishments benefit from their mutual proximity due to forward-backward linkages, labor market pooling and knowledge spillovers (the Marshallian forces). While the existence of these externalities as a whole is well supported by the empirical...

"The advent of the New Economic Geography has spawned a renewed interest in questions of agglomeration. The work expands the research on the impact of agglomeration economies on employment growth by connecting two strands of the empirical literature. A localization index and a cluster index are...

"Economic integration typically goes along with disintegration of production through outsourcing and offshoring (Feenstra 1998). As horizontal and vertical links between firms become more and more pronounced, value chains within regions are increasingly organized by production and innovation...

This paper examines the relationship between spatial clustering and inequality at the county scale with overall state per capita income in the U.S. over the period 1969-2000. For each of the 48 coterminous states we examine measures of inequality and spatial clustering and explore how a state's...

"The paper shows that the distribution of regional unemployment rates in Germany exhibits strong persistent behaviour. Furthermore, panel unit root tests and autoregressive fixed effects models indicate that regional unemployment rates display conditional rather than unconditional convergence....

"This paper explores how different levels of regional concentration and specialisation affect the long-term growth of young firms. The sample consists of knowledge-intensive and non-knowledge-intensive western German manufacturing firms which were set-up in 1992 and managed to survive 11 years....
