Unemployment insurance and job protection regulations provide assistance to those who face unemployment. Unemployment insurance seems more desirable, since it does not harm flexibility in the labour markets, but it entails a moral hazard risk. Making the unemployment insurance voluntary and...

In this paper the seasonal unit root test of Hylleberg et al. (1990) is generalized to cover a heterogenous panel. The procedure follows the work of Im, Pesaran and Shin (2002). Test statistics are proposed and critical values are obtained by simulations. Moreover, the properties of the tests...

The present paper compares expected inflation to (econometric) inflation forecasts based on a number of forecasting techniques from the literature using a panel of ten industrialized countries during the period of 1988 to 2007. To capture expected inflation we develop a recursive filtering...

This paper examines the presence of sectoral convergence of labor productivity between 14 OECD countries. Using the OECD International Sectoral Data Base (ISDB), the paper looks at the developments within 12 distinct sectors during the period 1970-1995. The change of the coefficients of variance...

EU-TE trade is increasingly characterised by intra-industry trade. For some countries (Czech Republic), the share of intra-industry trade in total trade with the EU approaches 60 percent. The decomposition of intra-industry trade into horizontal and vertical shares reveals overwhelming vertical...

In the presence of network externalities, demand is strongly affected by major technology diffusion processes. Therefore, not only sales levels, but also the installed user base of network technologies may influence R&D intensity via the price mechanism. This causality may, however, not be...

R&D activities by one industry often have positive effects on the productivity performance of other industries, as a consequence of technology spillovers. Econometric problems (such as multicollinearity), however, have prevented researchers from identifying the industries that have been...
