Wage Distributions by Bargaining Regime: Linked Employer-Employee Data Evidence from Germany

Using linked employer-employee data from the German Structure of Earnings Survey 2001, this paper provides a comprehensive picture of the wage structure in three wage-setting regimes prevalent in the German system of industrial relations. We analyze wage distributions for various labor market subgroups by means of kernel density estimation, variance decompositions, and individual and firm-level wage regressions. Unions' impact through collective and firm-level bargaining mainly works towards a higher wage level and reduced overall and residual wage dispersion. Yet observed effects are considerably heterogeneous across different labor market groups. There is no clear evidence for wage floors formed by collectively bargained low wage brackets which would operate as minimum wages for different groups of workers.Collective wage bargaining, wage structure, kernel density estimation, variance decomposition, wage equations, German Structure of Earnings Survey

Regionale Ordnungen in politischen Räumen. Ein Beitrag zur Theorie regionaler Ordnungen

Seit einiger Zeit stehen Regionen (wieder) auf der Agenda der Theoriediskussionen in den Internationalen Beziehungen. Es ist u.a. von einer „emerging regional architecture of world politics“ die Rede und von der Zukunft eines „multiregional system of international relations“ oder sogar einer „world of regions“. In dieser Perspektive geht es gegenwärtig nicht mehr allein um die Frage, welche Strukturvorgaben des internationalen Systems für eine neue Weltpolitik zu berücksichtigen sind. Vielmehr ist mit Blick auf die regionalen Ordnungen erforderlich zu fragen, wann und unter welchen Umständen die Strukturen und Akteurskonstellationen für regionale Kontexte überhaupt Bedeutung haben. Allerdings ist der politiktheoretische Status der Regionen in den Internationalen Beziehungen alles andere als klar. Mit diesem Beitrag werden zwei Ziele verfolgt: Einerseits wird die bisherige Diskussion mithilfe von drei Schlüsselkonzepten – Kooperation, Regionale Sicherheitskomplexe und Externalitäten – strukturiert; andererseits wird das konzeptionelle Verhältnis von Regionen, politischen Räumen und regionalen Ordnungen diskutiert. Dabei werden Kriterien – geografische Lage, politische Entscheidungen, Drittwirkungen dieser Entscheidungen – vorgestellt, die eine weiterführende Analyse verschiedener Typen regionaler Ordnungen ermöglichen.regionale Ordnung, Region/Regionalismus, Theorien Internationaler Beziehungen

Union Density and Varieties of Coverage: The Anatomy of Union Wage Effects in Germany

Collective bargaining in Germany takes place either at the industry level or at the firm level; collective bargaining coverage is much higher than union density; and not all employees in a covered firm are necessarily covered. This institutional setup suggests to explicitly distinguish union power as measured by net union density (NUD) in a labor market segment, coverage at the firm level, and coverage at the individual level. Using linked employer-employee data and applying quantile regressions, this is the first empirical paper which simultaneously analyzes these three dimensions of union influence on the structure of wages. Ceteris paribus, a higher share of employees in a firm covered by industry-wide or firm-level contracts is associated with higher wages. Yet, individual bargaining coverage in a covered firm shows a negative impact both on the wage level and on wage dispersion. A higher union density reinforces the effects of coverage, but the effect of union density is negative at all points in the wage distribution for uncovered employees. In line with an insurance motive, higher union density compresses the wage structure and, at the same time, it is associated with a uniform leftward movement of the distribution for uncovered employees.linked employer-employee data, quantile regression, wage structure, collective bargaining coverage, union density, Structure of Earnings Survey 2001, Germany

Home computers and married women's labor supply

I consider how the availability of a personal computer at home changed employment for married women. I develop a theoretical model that motivates the empirical specifications. Using data from the U.S. CPS from 1984 to 2003, I find that employment is 1.5 to 7 percentage points higher for women in households with a computer. The model predicts that the increase in employment is driven by higher wages. I find having a computer at home is associated with higher wages, and employment in more computer intensive occupations, which is consistent with the model. Decomposing the changes by educational attainment shows that both women with low levels of education (high school diploma or less) and women with the highest levels of education (Master's degree or more) have high returns from home computer

Regional Orders in Political Spaces. A Contribution to the Theory of Regional Orders

Seit einiger Zeit stehen Regionen (wieder) auf der Agenda der Theoriediskussionen in den Internationalen Beziehungen. Es ist u.a. von einer 'emerging regional architecture of world politics' die Rede und von der Zukunft eines 'multiregional system of international relations' oder sogar einer 'world of regions'. In dieser Perspektive geht es gegenwärtig nicht mehr allein um die Frage, welche Strukturvorgaben des internationalen Systems für eine neue Weltpolitik zu berücksichtigen sind. Vielmehr ist mit Blick auf die regionalen Ordnungen erforderlich zu fragen, wann und unter welchen Umständen die Strukturen und Akteurskonstellationen für regionale Kontexte überhaupt Bedeutung haben. Allerdings ist der politiktheoretische Status der Regionen in den Internationalen Beziehungen alles andere als klar. Mit diesem Beitrag werden zwei Ziele verfolgt: Einerseits wird die bisherige Diskussion mithilfe von drei Schlüsselkonzepten - Kooperation, Regionale Sicherheitskomplexe und Externalitäten - strukturiert; andererseits wird das konzeptionelle Verhältnis von Regionen, politischen Räumen und regionalen Ordnungen diskutiert. Dabei werden Kriterien - geografische Lage, politische Entscheidungen, Drittwirkungen dieser Entscheidungen - vorgestellt, die eine weiterführende Analyse verschiedener Typen regionaler Ordnungen ermöglichen.The concept of regions is once again on the agenda of international relations theory (IRT). Scholars are speaking of an 'emerging regional architecture of world politics' - or the future of a 'multiregional system of international relations' or even a 'world of regions'. The question is no longer which structural parameters of the international system are determining world politics, but rather - with regard to regional orders - when and under what conditions structures and actors actually become important (gain meaning) for regional contexts. The heuristic status of regions in IRT, however, remains vague. The purpose of this article is twofold: firstly, we structure the previous debate around three key concepts: cooperation, regional security complex, and externalities; secondly, we discuss the conceptual link between regions, political spaces, and regional orders. Finally, we introduce central criteria such as geographic proximity, political decision-making, and the effects of interactions on third-parties which further facilitate related work on different types of regional orders

Systematic review and meta-analysis. small intestinal bacterial overgrowth in chronic pancreatitis

BACKGROUND: Evidence on small intestinal bacterial overgrowth (SIBO) in patients with chronic pancreatitis (CP) is conflicting. AIM: The purpose of this study was to perform a systematic review and meta-analysis on the prevalence of SIBO in CP and to examine the relationship of SIBO with symptoms and nutritional status. METHODS: Case-control and cross-sectional studies investigating SIBO in CP patients were analysed. The prevalence of positive tests was pooled across studies, and the rate of positivity between CP cases and controls was calculated. RESULTS: In nine studies containing 336 CP patients, the pooled prevalence of SIBO was 36% (95% confidence interval (CI) 17-60%) with considerable heterogeneity (I2 = 91%). A sensitivity analysis excluding studies employing lactulose breath test gave a pooled prevalence of 21.7% (95% CI 12.7-34.5%) with lower heterogeneity (I2 = 56%). The odds ratio for a positive test in CP vs controls was 4.1 (95% CI 1.6-10.4) (I2 = 59.7%). The relationship between symptoms and SIBO in CP patients varied across studies, and the treatment of SIBO was associated with clinical improvement. CONCLUSIONS: One-third of CP patients have SIBO, with a significantly increased risk over controls, although results are heterogeneous, and studies carry several limitations. The impact of SIBO and its treatment in CP patients deserve further investigation

What makes cities more productive? Agglomeration economies and the role of urban governance: evidence from 5 OECD countries

This paper estimates agglomeration benefits across five OECD countries, and represents the first empirical analysis that combines evidence on agglomeration benefits and the productivity impact of metropolitan governance structures, while taking into account the potential sorting of individuals across cities. The comparability of results in a multi-country setting is supported through the use of a new internationally-harmonised definition of cities based on economic linkages rather than administrative boundaries. In line with the literature, the analysis confirms that city productivity increases with city size but finds that cities with fragmented governance structures tend to have lower levels of productivity. This effect is mitigated by the existence of a metropolitan governance body

Influence of causal attributions on Emotional and Behavioral Reactions of care workers towards challenging Behavior among persons with deafblindness

A large quantity of research on Challenging Behavior (CB) has focused on persons with intellectual disabilities. However, individuals with deafblindness also commonly engage in CB. The present study asked 63 staff members of institutions that work with persons with deafblindness in eight countries about their experiences with CB, in which situations CB occurs, and how they react in such situations. Furthermore, we investigated the relationship between staff members’ attributions to CB, i.e. the underlying reasons staff members ascribe to CB, and their emotional reactions. The main finding showed that those persons who endorsed communicative difficulties as underlying reason of CB were more likely to experience fear and anxiety than persons who endorsed other causal attributions. This was interpreted as a result from increased feelings of responsibility for the client. Nevertheless, confidence and comfort were the most common emotional responses. The present study is the first one that provides an overview of attributions and emotions to CB among care workers that work with persons with deafblindness. Influence of CB on care workers has been neglected in this field so far. This study is also the first that considered measuring a communicative attribution to CB next to attributions of behavioral processes, stimulation, environmental, emotional and biomedical explanations

Essays in labor economics

My thesis combines three distinct papers in labor economics. The first chapter is a collaborative work with Bernd Fitzenberger and Karsten Kohn. In this chapter we scrutinize the effects of union density and of collective bargaining coverage on the distribution of wages both in the covered and the uncovered sector. Collective bargaining in Germany takes place at either the industry or firm level. Collective bargaining coverage is much greater than union density. The share of employees covered by collective bargaining in a single firm can vary between 0% and 100%. This institutional setup suggests that researchers should explicitly distinguish union density, coverage rate at the firm level, and coverage at the individual level. Using linked employer-employee data, we estimate OLS and quantile regressions of wages on these dimensions of union influence. A higher share of employees in a firm covered by industry-wide or firm-specific contracts is associated with higher wages, but there is no clear-cut effect on wage dispersion. Yet, holding coverage at the firm level constant, individual bargaining coverage is associated with a lower wage level and less wage dispersion. A greater union density reinforces the effects of coverage, but the effect of union density is negative at all points of the wage distribution for employees who work in firms without collective bargaining coverage. Greater union density thus compresses the wage distribution while moving the distribution in firms without coverage uniformly. The second chapter evaluates the impact of the UK Working Time Regulations 1998, which introduced mandatory paid holiday entitlement. The regulation gave(nearly) all workers the right to a minimum of 4 weeks of paid holiday per a year. With constant weekly pay this change amounts effectively to an increase in the real hourly wage of about 8.5% for someone going from 0 to 4 weeks paid holiday per year, which should lead to adjustments in employment. For employees I use complementary log-log regression to account for right-censoring of employment spells. I find no increase in the hazard to exit employment within a year after treatment. Adjustments in wages cannot explain this result as they are increasing for the treated groups relative to the control. I also evaluate the long run trend in aggregate employment, using the predicted treatment probabilities in a difference-in-differences framework. Here I find a small and statistically significant decrease in employment. This effect is driven by a trend reversal in employment, coinciding with the treatment. The third chapter considers how the availability of a personal computer at home changed employment for married women. I develop a theoretical model that motivates the empirical specifications. Using data from the U.S. CPS from 1984 to 2003, I find that employment is 1.5 to 7 percentage points higher for women in households with a computer. The model predicts that the increase in employment is driven by higher wages. I find having a computer at home is associated with higher wages, and employment in more computer intensive occupations, which is consistent with the model. Decomposing the changes by educational attainment shows that both women with low levels of education (high school diploma or less) and women with the highest levels of education (Master's degree or more) have high returns from home computers
