We test Krugman’s (1991) notion of risk sharing in pooled labormarkets as one of the micro-foundations of agglomerationeconomies, i.e. we examine whether firms share risks fromidiosyncratic and sector specific shocks through labor pooling.Estimating wage functions we find that job turnover...

In this paper we survey the recent developments in two empirical literatures at the crossroadsof labor and urban economics: Studies about localized human capital externalities (HCE) andabout the urban wage premium (UWP). After surveying the methods and main results of eachof these two...

We analyze the equilibrium and the optimal resource allocations in a monocentric city undermonopolistic competition. Unlike the constant elasticity of substitution (CES) case, wherethe equilibrium markups are independent of the city size, we present a variable elasticity ofsubstitution (VES)...

This paper sheds new light on the role of regional labor market conditions for regional mobility. We study competition for vacant jobs along two dimensions - between employed and unemployed job searchers, and between resident and non-resident job searchers - within a simple matching framework....

Nationale rechtliche Rahmenbedingungen beeinflussen die Möglichkeiten für wirtschaftliche Aktivitäten multinationaler Unternehmen (MNU) in einem Gastland und der Koordination zwischen den Unternehmensteilen in verschiedenen Ländern. Sie sind damit wichtige Bestimmungsfaktoren für...

Discretionary disclosure theory suggests that firms incentives to provide proprietary versus non-proprietary information differ markedly. To test this conjecture, the paper investigates the incentives of German firms to voluntarily disclose business segment reports and cash flow statements in...

This paper documents the relationship between foreign ownership and firm survival forenterprises in Germany using unique tailor-made new representative data that mergeinformation from surveys performed by the Statistical Offices, from administrative datacollected by the Tax Authorities and from...

This paper examines the determinants of intra-firm trade in U.S. imports using detailed country-productdata. We create a new measure of product contractibility based on the degree of intermediation in internationaltrade for the product. We find important roles for the interaction of country and...

Empirical studies on information communication technologies (ICT) typically aggregate the“information” and “communication” components together. We show theoretically and empirically thatthese have very different effects on the empowerment of employees, and by extension on wageinequality....

The principal argument for subsidizing foreign investment, especially in developing andtransition economies, is the assumed spillover of technology to local firms. Yet researchersreport mixed results on spillovers. To examine the phenomenon in a systematic way, wecollected 3,626 estimates from...
