We wish to reconcile the major trends in wages and the terms of trade using a directed technical change approach in which: (i) tradable and nontradable goods can be substitutes or complements; and (ii) scale effects can be present or can be partially or totally removed. With a lower skilled labour ratio and a higher relative wage in the tradable sector, the price (real exchange rate or terms of trade) mechanism is crucial in determining sectoral productivity differences and thus wage inequality. Along the balanced growth path, the real exchange rate can be negatively related with the relative productivities in horizontal innovation (the Balassa-Samuelson effect) and with the relative labour level, depending on scale effects. The wage premium increases due to an increase in the relative labour level in the nontradable sector under substitutability with scale effects or under complementarity without scale effects. A calibrated version of the model indicates that the model closely replicates the data for Germany. Moreover, while the Balassa-Samuelson effect is quantified, an increase in the relative supply of labour in the tradable sector decreases both terms of trade and inequality. [ABSTRACT FROM AUTHOR]

This study empirically examines the sources of fluctuations in hours worked in Canada, Germany, Japan and the U.S. It is particularly motivated by Galí's (1999) VAR study, which demonstrates that a positive technology shock reduces hours worked, at least in the short run. However, in the present study, a technology shock is identified without recourse to Galí's long-run restriction, which has been subject to active controversy. Furthermore, this study uncovers other important sources of fluctuations in hours worked to reflect the concern, raised by numerous studies, that technology shocks leave most variations in hours worked unexplained. Specifically, there are six shocks underlying our model, and they are identified using a set of sign restrictions. The empirical results confirm that in all four countries, a positive technology shock significantly reduces hours worked. This technology shock, along with labor supply and demand shocks, accounts for most of the short-term variations in hours worked. As the forecasting horizon increases, technology and demand shocks become less important, whereas labor supply shocks contribute to explaining the bulk of long-run variations in hours worked. Finally, the empirical relevance of Galí's longrun identification restriction is tested and the results are related to those obtained using the sign restriction model. [ABSTRACT FROM AUTHOR]

We sharpen tests for ‘discouragement’ and ‘added worker’ effects by splitting the explanatory variable – the unemployment rate – into a short-term component and a long-term component. While short-term unemployment (STU) might not result in additional workers on a large scale, long-term unemployment (LTU) reduces household income more, increasing the need for additional income. On the other hand, it may discourage older workers for psychological and sociological reasons. Applying our model to the German labour market, these hypotheses could be confirmed. Even for men, about whom only a few empirical studies on this issue are available, distinguishing between STU and LTU reveals added worker as well as discouragement effects.

This article estimates the long-term legacies of female labour force mobilization on women’s family formation outcomes such as marriage, age at first marriage and divorce. We identify the long-term marriage effects of female labour force mobilization by exploring postwar mandatory employment in Germany. Using difference-in-differences analysis, we find that participation in postwar reconstruction efforts increased women’s probability of being currently married, ever married and marrying at younger ages. We also find that postwar employment had no differential effect on divorce rates of the affected cohorts of women. These results persist after accounting for the potential changes in the composition of the population, demand for female labour, war relief payments and postwar state-specific policies.
