Informal sector labour demand is analysed using a matched employer-employee data set obtained from a survey of informal enterprises in South-western Nigeria. Two different methodological approaches are used: conventional Ordinary Least Squares (OLS) and Instrumental Variable (IV) estimation...

This document studies the effects of business informality in terms of distortions in resource absorption, particularly labor, by informal companies. It also assesses the consequences of lower demand for labor of informal firms over aggregate productivity. With firm level data from the DANE...

I study welfare and distributional effects of import tariffs in a two-country asymmetric general oligopolistic equilibrium trade model. Tariffs have an anti-competitive effect that reduces labor demand because firms want to shorten supply. Unilaterally increasing the import tariff in absence of...

We analyze the economic factors which have contributed to the dramatic decline of the employment share of unskilled labor in German manufacturing, in particular the role played by the relatively rigid earnings structure. Potential effects of intensified international competition and skill?biased...

During the last two decades, the labour demand structure in Germany has experienced a decrease in the demand for the low skilled. Possible explanations for this trend are investigated in this study for West Germany (1994- 1997) using a unique linked employer-employee panel data set for Germany....

Investigating the robustness of the skill-biased technical change hypothesis, this analysis incorporates two novel features. First, effective labor is modeled as the product of a quantity measure - number of employees with a given level of education - and a quality index, depending on, i.a.,...

In den letzten Jahren sind verschiedene empirische Studien zu den Beschäftigungswirkungen eines gesetzlichen Mindestlohns in Deutschland erschienen. Die Bandbreite der simulierten Job-Verluste reicht von 140 000 bis 1,2 Millionen. Eine neue Studie des DIW Berlin auf der Basis von Daten des...

In this paper, we develop an allocation model of workers differentiated by their field of study to test whether international differences in the wage structure can be explained by differences in labor demand and supply in each country. The model explicitly takes into account the effects of...

This paper examines the impact of innovations and wages on the demand for heterogeneous labour. Based on matched data from the IAB-establishment panel survey and the files of the employment statistics register for the year 1995, input shares derived from a generalised Leontief cost function are...

In Germany we observe a decline in regular employment and an increase in atypical forms of employment. Especially marginal part-time employment which is characterized by lower tax rates and lower social security contributions increased substantially after a reform in 2003 made this type of...
