    A North-South Model of Trade with Search Unemployment

    27 July 2016

    In this paper I build a North-South model of international trade, economic growth and search-frictional unemployment in the North. Growth is driven by a process of creative destruction in the North followed by imitation in the South. I study the effects of intellectual property rights protection and trade liberalization on unemployment and welfare in the North. Intellectual property rights protection decreases unemployment and increases welfare. Trade liberalization increases welfare but has an ambiguous effect on unemployment. It decreases unemployment if workers in the North have a high outside option and increases it if their outside option is low. I provide empirical evidence in support of the last result using data for 20 OECD countries.

    Technological progress and (un)employment development

    14 July 2016

    In this paper the authors have presented research on the theorem about the employment effects of productivity growth under different conditions of product demand. In a first step they have developed a simple theoretical model establishing the relationship between technological progress and employment. This model has then been generalized taking the labour market explicitly into account which allows explaining unemployment and endogenising wages.

    Inter-industry labor flows

    28 June 2016

    Labor flows across industries reallocate resources and diffuse knowledge among economic activities. However, surprisingly little is known about the structure of such inter-industry flows. Using German social security data, we generate stylized facts about inter-industry Labor mobility and explore its consequences.

    Identifying macroeconomic effects of refugee migration to Germany

    17 June 2016
    This study investigates impacts of migration on the German economy, explicitly distinguishing refugee and non-refugee immigration. We propose a macroeconometric modelling approach complemented by instrumental variable techniques. We find that non-refugee immigration has more beneficial medium-run effects on GDP and the labour market.

    Firms and labor market inequality

    15 June 2016

    The authors review the literature on firm-level drivers of labor market inequality. There is strong evidence from a variety of fields that standard measures of productivity — like output per worker or total factor productivity — vary substantially across firms, even within narrowly-defined industries. Several recent studies note that rising trends in the dispersion of productivity across firms mirror the trends in the wage inequality across workers.

    Does marginal employment promote regular employment for unemployed welfare benefit recipients in Germany?

    14 June 2016

    Marginal employment (ME) is one of the largest forms of atypical employment in Germany. In this study, the authors analyse whether ME has a “stepping stone” function for unemployed individuals, i.e., whether ME increases the subsequent probability of regular employment. This study adds to the literature in the following ways. First, compared to previous studies, it analyses the “stepping stone” function for a more recent time period, i.e., after Germany’s major labour-market reforms (Hartz reforms) at the beginning of the 2000s. Second, the authors use a new administrative data source which includes previously unavailable information on desired labour supply and household composition. Third, they follow recent methodological developments in the evaluation literature by applying a dynamic evaluation approach that has not previously been used to analyse marginal employment.

    Exchange Rate Effects of a Potential Brexit on German-UK Bilateral Trade

    07 June 2016

    On June 23rd the United Kingdom and Gibraltar will hold a referendum whether to stay in the European Union or not. The topic of what the consequences may be is rather large spanning many aspects of social, political and economic life. In this current report we look at bilateral German-UK trade and its short-run sensitivity to exchange rate fluctuations. We look at the trade numbers and explain what this sen-sitivity means.

    Revision of the IAB Job Vacancy Survey

    07 June 2016

    The German Job Vacancy Survey delivers representative data on the number and structure of vacancies in Germany. Such data cannot be derived from other sources and are therefore unique. The survey includes registered and non-registered vacancies. In course of extensive tests and reviews a new extrapolation procedure has been developed. As a result, the aggregate number of vacancies is revised downwards.

    The research report is organised as follows: Firstly, an overview about the aim and content of the German Job Vacancy Survey is given. Subsequently, the evolution of the new extrapolation procedure is described. Thirdly, the new method is presented and it is shown that the adaption of it significantly improves the quality of the Survey results.
