One puzzling behavior of asset returns for various frequencies is the often observed positive autocorrelation at lag 1. To some extent this can be explained by standard asset pricing models when assuming time varying risk premia. However, one often finds better results when directly fitting an...

In this paper we introduce a bootstrap procedure to test parameter restrictions in vector autoregressive models which is robust in cases of conditionally heteroskedastic error terms. The adopted wild bootstrap method does not require any parametric specification of the volatility process and...

This paper investigates whether job stability in western Germany shows any signs of decline and compares the findings to evidence for the US and the UK. Cross sectional data and calendar information from the German Socioeconomic Panel 1984-1997 are combined allowing to check possible influences...

Daily returns of financial assets are frequently found to exhibit positive autocorrelation at lag 1. When specifying a linear AR(l) conditional mean, one may ask how this predictability affects option prices. We investigate the dependence of option prices on autoregressive dynamics under...

This paper investigates the effect of displacement on reemployment wages of socially insured West German workers who became unemployed in 1986. Because detailed information on the cause of job loss is unavailable, displacement status is imputed using a probit estimated on the German...

The impact of general and specific training on income and mobility is an important issue for the discussion around human capital as well as the design of educational systems. Using data from two retrospective life-history surveys this paper examines the impact of more general school-based...
