Divergence in labour force growth : should wages and prices grow faster in Germany?
(2020) Marczak, Martyna; Hellier, Joël; Beißinger, Thomas
We develop a model which shows that wages, prices and real income should grow faster in countries with low increase in their labour force. If not, other countries experience growing unemployment and/or trade deficit. This result is applied to the case of Germany, which has displayed a significantly lower increase in its labour force than its trade partners, except in the moment of the reunification. By assuming that goods are differentiated according to their country of origin (Armington’s hypothesis), a low growth of the working population constrains the production of German goods, which entails an increase in their prices and in German wages. This mechanism is magnified by the low price elasticity of the demand for German goods.Hence,the German policy of wage moderation could severely constrain other countries’ policy options. The simulations of an extended model which encompasses offshoring to emerging countries and labour market imperfections suggest that (i) the impact of differences in labour force growth upon unemployment in Eurozone countries has been significant and (ii) the German demographic shock following unification could explain a large part of the 1995-2005 German economic turmoil.
Does regulation trade-off quality against inequality? : The case of German architects and construction engineers
(2018) Strohmaier, Kristina; Rostam-Afschar, Davud
We exploit an exogenous price increase by about 10% for architectural services to answer the question how price regulation affects income inequality and service quality. Using individual-level data from the German microcensus for the years 2006 to 2012, we find a significant reform effect of 8% on personal net income for self-employed architects and construction engineers. This group moved from the second lowest to the highest quintile of the net income distribution. This increase in inequality is associated with a deterioration of service quality. The reform reduced average scores of a peer ranking for architects by 18%.
Entry regulation and competition : evidence from retail and labormarkets of pharmacists
(2021) Unsorg, Maximiliane; Rostam-Afschar, Davud
We examine a deregulation of German pharmacists to assess its effects on retail and labor markets. From 2004 onward, the reform allowed pharmacists to expand their single-store firms and to open or acquire up to three affliated stores. This partial deregulation of multi-store prohibition reduced the cost of firm expansion substantially and provides the basis for our analysis. We develop a theoretical model that suggests that the general limitation of the total store number per firm to four is excessively restrictive. Firms with high managerial effciency will open more stores per furm and have higher labor demand. Our empirical analysis uses very rich information from the administrative panel data on the universe of pharmacies from 2002 to 2009 and their affiliated stores matched with survey data, which provide additional information on the characteristics of expanding firms before and after the reform. We find a sharp immediate increase in entry rates, which continues to be more than five-fold of its pre-reform level after five years for expanding firms. Expanding firms can double revenues but not profits after three years. We show that the increase of the number of employees by 50% after five years and the higher overall employment in the local markets, which increased by 40%, can be attributed to the deregulation.
Essays on the impact of temporary agency work on wages and employment
(2018) Baudy, Philipp; Beißinger, Thomas
The thesis contributes to the theoretical discussion of the effects of temporary agency work and picks up three different issues that have not been analyzed yet. It provides three theoretical models 1) to discuss the optimal economic behavior of firms and labor unions when firms threaten to use temporary agency employment in the bargaining process, 2) to examine the macroeconomic effects of the deregulation of temporary agency work that took, and still takes, place in many countries in the last decades, and 3) to study how the technological choice of firms in the economy changes due to the legal deregulation of temporary agency work. The first model focuses on the question of the optimal economic behavior of the bargaining parties. Developing a monopoly union model, it analyzes how and to what extent firms can strategically use the threat of temporary agency employment to dampen the wage claims of labor unions. Furthermore, the model discusses how labor unions optimally behave and respond to these threats. It is shown that labor unions may find it optimal to accept lower wages to prevent firms from using temporary agency workers. The decision of the labor union to oppose or accept the firms threat is based on the attempt to minimize the loss in its utility. While labor unions suffer from the potential use of temporary agency employment in terms of their utility, firms gain from increasing profits and an extended employment level per firm. If unions do not oppose temporary agency work, the model suggests that labor unions increase their wage claims for the remaining regular workers to a level that even exceeds the claims of the labor union if there is no threat at all. Hence, an intensive use of temporary agency workers in high-wage firms may be the cause and not the consequence of the high wage level in those firms. The second model concentrates on the effects of the deregulation of temporary agency employment on macroeconomic determinants like wages, unemployment, and the employment structure. Using the matching framework, it provides a first contribution that combines labor unions and temporary agency work in this modeling setup. Large firms produce differentiated goods employing regular workers that are organized in labor unions and, optionally, using temporary agency work for parts of the production. Furthermore, there is a special emphasis on the flows from temporary agency to regular employment, which is modeled as on-the-job search. The model shows that the deregulation of temporary agency work leads to a reduction in overall unemployment. Surprisingly, this favors regular employment due to lower wages that arise from the impact that the more attractive production alternative temporary agency employment has on labor union wage bargaining. The most interesting finding, however, is that there is a hump-shaped relationship between the degree of institutional deregulation of temporary agency work and its rate of employment. This is explained by the fact that voluntary non-institutional, firm-level regulations come into play and get the more important, the less regulated temporary agency employment is. They have a counter-effect on the costs of temporary agency work that is lowered by the deregulation. Additionally, even if the model does not conceal that individual workers suffer from declining wages, it shows that regular employment benefits from the deregulation of temporary agency employment. The third model examines how the technological choice of firms in an economy changes due to the availability of temporary agency employment as a production alternative that gets cheaper and, therefore, more attractive the less regulated it is. The model uses the matching framework with two types of jobs that differ in their productivity and workers that are randomly matched with temporary or regular job vacancies. The analysis reveals how the decision of firms with which technology to enter the market and to produce with changes with the deregulation of temporary agency employment. Regular and temporary agency workers produce the same good but use different technologies. Temporary agency work is less expensive to hire than regular workers as direct labor costs are lower. However, job destruction and labor turnover is higher in this employment type. The model rather intuitively suggests that the legal deregulation of temporary agency employment deteriorates the technology level used in the economy, leads to a more intensive use of the less advanced technology, and increases temporary agency employment. Regular workers are shown to suffer from declining wages while the labor income of temporary agency workers increases. However, the model also provides an advice for economic policy by suggesting that subsidies or other forms of support for directed investments in technological progress of more advanced technologies may be suitable to dampen the macroeconomic effects of the deregulation of temporary agency employment.
Mapping Stratification : the industry-occupationspace reveals the network structure ofinequality
(2019) Gala, Paulo; Kaltenberg, Mary; Jara-Figueroa, Cristian; Hartmann, Dominik
Social stratification is determined not only by income, education, race, and gender, but also by an individual’s job characteristics and their position in the industrial structure. Utilizing a dataset of 76.6 million Brazilian workers and methods from network science, we map the Brazilian Industry-Occupation Space (BIOS). The BIOS measures the extent to which 600 occupations co-appear in 585 industries, resulting in a complex network that shows how industrial-occupational communities provide important information on the network segmentation of society. Gender, race, education, and income are concentrated unevenly across the core-periphery structure of the BIOS. Moreover, we identify 28 industrial occupational communities from the BIOS network structure and report their contribution to total income inequality in Brazil. Finally, we quantify the relative poverty within these communities. In sum, the BIOS reveals how the coupling of industries and occupations contributes to mapping social stratification.
Occupational licensing and the gender wage gap
(2020) Rostam-Afschar, Davud; Pagliero, Mario; Koumenta, Maria
We use a unique survey of the EU labor force to investigate the relationship between occupational licensing and the gender wage gap. We find that the gender wage gap is canceled for licensed self-employed workers. However, this closure of the gender wage gap is not mirrored by significant changes in the gender gap inhours worked. Our results are robust using decomposition methods, quantile regressions, different datasets, and selection correction.
Occupational regulation, institutions, and migrants labor market outcomes
(2022) Koumenta, Maria; Pagliero, Mario; Rostam-Afschar, Davud
We study how licensing, certification and unionisation affect the wages of natives and migrants and their representation among licensed, certified, and unionized workers. We provide evidence of a dual role of labor market institutions, which both screen workers based on unobservable characteristics and also provide them with wage setting power. Labor market institutions confer significant wage premia to native workers (3.9, 1.6, and 2.7 log points for licensing, certification, and unionization respectively), due to screening and wage setting power. Wage premia are significantly larger for licensed and certified migrants (10.2 and 6.6 log points), reflecting a more intense screening of migrant than native workers. The representation of migrants among licensed (but not certified or unionized) workers is 14% lower than that of natives. This implies a more intense screening of migrants by licensing institutions than by certification and unionization.
