Automatisierung, Wachstum und Ungleichheit
(2018) Schwarzer, Johannes; Prettner, Klaus; Geiger, Niels
Die Automatisierung stellt eines der wichtigsten Phänomene dar, welche aktuell innerhalb der Wirtschaftswissenschaften und der breiteren Öffentlichkeit diskutiert werden. Dabei finden sich in Bezug auf die Frage, wie sich die Automatisierung gesamtwirtschaftlich auswirkt, sehr unterschiedliche Positionen: Am einen Ende wird auf die negativen Beschäftigungseffekte verwiesen, wenn Menschen mehr und mehr durch Maschinen ersetzt werden und ihre am Markt angebotene Arbeitsleistung nicht mehr nachgefragt somit obsolet wird. Gleichzeitig wird die Automatisierung auch für einen Anstieg der wirtschaftlichen Ungleichheit verantwortlich gemacht. Optimistischere Stimmen verweisen andererseits auf die Entwicklung seit der Industriellen Revolution, die durch fortlaufende technologische Veränderungen mit hohem Produktivitätswachstum und damit starken Wohlfahrtssteigerungen einherging, ohne dass es langfristig zu Massenarbeitslosigkeit gekommen ist. Der vorliegende Aufsatz diskutiert einige allgemein relevante empirische Daten und skizziert ein einfaches theoretisches Wachstumsmodell zur Analyse der Automatisierung. Die hierbei festgehaltenen Ergebnisse werden unter Bezugnahme auf die aktuelle wirtschaftswissenschaftliche Literatur zu den bisherigen und für die Zukunft zu erwartenden ökonomischen Effekten der Automatisierung vertieft und erweitert. Aus den verschiedenen Ansatzpunkten und Überlegungen werden schließlich wirtschaftspolitische Handlungsmöglichkeiten abgeleitet, wobei auch jeweils diskutiert wird, welchen Einschränkungen diese Maßnahmen unterliegen.
Divergence, convergence, and the history-augmented Solow model
(2017) Kufenko, Vadim; Prettner, Klaus; Geloso, Vincent
We test the history-augmented Solow model with respect to its predictions on the patterns of divergence and convergence between the nowadays industrialized countries of the OECD. We show that the dispersion of incomes increased after the Indus- trial Revolution, peaked during the Second World War, and decreased afterwards. This pattern is fully consistent with the transitional dynamics implied by the history-augmented Solow model.
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%.
Essays on tackling economic inequalities
(2016) Fuchs, Benjamin; Osikominu, Aderonke
This thesis provides a differentiated picture of two interventions and one policy reform to alleviate economic inequality. In two chapters this dissertation examines whether out-of-school activities affect behavioral outcomes reflecting character, social and executive function skills. The first essay in this thesis analyzes the effect of performing sports on a regular basis on the formation of character and social skills. The findings confirm that sports is generally a social activity. For youths from less advantaged family backgrounds sports constitutes often the only quality pastime they engage in. Athletic involvement has beneficial effects on a broad range of character skills. These effects are largely driven by youths who do not engage in any other structured activity. Further, the effects can be interpreted as a broader effect of having access to an enriched social environment. The second essay examines the effect of working part-time while attending full-time schooling on the development of character skills and occupational choice strategies. Comparing adolescents who hold a job with adolescents who do not work, the former spend less time in front of a screen and invest more time in academic learning. Focusing on the time use of employed adolescents, working part-time has an ambivalent effect on time invested in other activities. It reduces their homework time as well as their nonproductive screen time. The results imply that holding a paid job while still in school reduces the uncertainty about own interests and talents and reduces the dependency on parents. A third essay evaluates the impact of the Tenancy Law Reform Act in 2001, a policy which targets to protect especially low-income households against rent increase. Germany is one of the European countries with the highest percentage of the population who lives in tenancies. This illustrates the importance of a functioning tenancy law, socially and economically. This essay analyzes the effect of the reform on the level of rents as well as on the residency discount. The two substantial parts of the reform were the reduction of the maximum rent increases for sitting tenants and the reduction of the minimum notice period until termination of a tenancy by the tenant. Estimating the effect over the distribution of rents, the reform shows a significant negative effect on rents that is stronger at higher quantiles. The annual residency discount increases with the reform during the first three years of a tenancy and vanishes thereafter. The evidence suggests that the reform was successful in curtailing rent increases especially for expensive apartments early in a tenancy. This thesis provides a differentiated picture on how economic inequalities can be alleviated. On the one side, this thesis focuses on the formation of character skills which are helpful for bringing especially unskilled people into employment and to better paid jobs. On the other side, this thesis focuses on a tenancy law reform that targeted to protect tenants against rent increases. While beneficial effects of structured leisure activities on the formation of character skills can be detected, one may be concerned that the tenancy law reform may not have been sufficiently targeted if considering the target of the reform to protect especially low-income households against rent increases.
Higher education and the fall and rise of inequality
(2016) Prettner, Klaus; Schaefer, Andreas
We investigate the effect of higher education on the evolution of inequality. In so doing we propose a novel overlapping generations model with three social classes: the rich, the middle class, and the poor. We show that there is an initial phase in which no social class invests in higher education of their children such that inequality is driven by bequests. Once a certain income threshold is surpassed, the rich start to invest in higher education of their children, which partially crowds out bequests and thereby reduces income inequality and inheritance flows in the short run. The better educated children of the rich, however, enjoy higher incomes such that inequality starts to rise again. As time goes by, the middle class and potentially also the poor start to invest in higher education. As the economy proceeds toward a balanced growth path, educational differences between social groups and thus inequality decline again. We argue that (1) the proposed mechanism has the potential to explain the U-shaped evolution of income inequality and inheritance flows in rich countries as well as the differential investments in higher education by richer and poorer households, (2) the currently observed increase in inequality is likely to level off in the future.
Inequality and guard labor, or prohibition and guard labor?
(2017) Kufenko, Vadim; Geloso, Vincent
In this paper, we consider whether or not inequality forces society to expend more resources on supervision which imposes an extra cost to doing business. Some argue that since inequality deteriorates social capital, there is a greater need for supervisory labor which is a costly burden to bear. We propose an alternative (but not mutually exclusive) explanation. We argue that the war on drugs leads to institutional decay and lower levels of trust which, in turn, force private actors to deploy resources to supervise workers and protect themselves. Our explanation complements the argument regarding the link between inequality and guard labor.
International trade, development traps, and the core-periphery structure of income inequality
(2019) Pinheiro, Flávio L.; Lodolo, Beatrice; Bezerra, Mayra; Hartmann, Dominik
Research on economic complexity has shown that a country’s type of exports conditions its future path of economic diversification and economic growth. Yet little emphasis has been put on the inequality associated with the types of products traded between countries and different regions of the world. Here we analyze the income inequality associated with the imports and exports of 116 countries in the period from 1970 to 2010. Our analysis shows that methods from network science and visual complexity research can help to reevaluate old theories in economics, such as coreperiphery structures in international trade or structural development traps. Our results illustrate that the core-periphery structure of global trade affects not only the income inequality between countries, but also the income inequality within countries. Moreover, they reveal the structural constraints that developing and emerging economies face in promoting inclusive growth and benchmark their productive transformations with cases of successful catching up and developed economies. The results show that countries, such as South Korea or Germany, have benefited from outsourcing high inequality products. In contrast, some middle-income countries, such as Brazil or South Africa, face structural development constraints consisting of a large average distance of their export products to low inequality products and a “gravitational force” towards high inequality products. Finally, developing economies, such as Nicaragua or Sri Lanka face a double development trap for inclusive growth, as their economies depend on both a large share of high inequality exports and imports.
Non-financial hurdles for human capital accumulation : landownership in Korea under Japanese rule
(2014) Kim, Tai-Yoo; Jun, Bogang
This paper suggests that inequality in landownership is a nonfinancial hurdle for human capital accumulation. It is the first to present evidence that inequality in landownership had an adverse effect on the level of public education in the Korean colonial period. Using a fixed effects model, the present research exploits variations in inequality in land concentration across regions in Korea and accounts for the unobserved heterogeneity across these regions. The analysis establishes a highly significant adverse effect of Land inequality on education in the Korean colonial period.
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.
Political implications of economic inequality : a literature survey
(2019) Geiger, Niels; Baric, Laura-Kristin
This survey documents the different arguments discussed in the academic literature on whether and how economic inequality and the emergence and stability of democratic political systems are connected. While early research in this domain has often focused on new and emerging democracies, this paper also provides an overview of the more recent literature in economics and neighboring fields that discusses democratization as well as established democracies’ stability and other institutional traits. In doing so, the survey contains a critical review of both theoretical and empirical contributions on the topic. The different arguments are systematically evaluated and their core hypotheses are distilled in order to document the main lines of argumentation prevalent in the literature. Together with a summary of the theoretical arguments, the main findings of related empirical research are also documented and shortly discussed. Whereas taken together, research so far generally does not suggest any conclusive results concerning economic inequality and the emergence of democracies, the survey indicates that the stability and institutional quality of established democracies can be negatively affected by economic inequality, and it outlines the conditions for this to occur. However, additional research especially on some of the more tentative hypotheses is required to allow for a more profound understanding of the different channels and relationships. Therefore, points of departure for further research, e. g. on how to operationalize specific theoretical constructs of interest and thereby on how to get a better understanding of the relations, are also suggested.
The lost race against the machine : automation, education and inequality in an R&D-based growth model
(2017) Prettner, Klaus; Strulik, Holger
We analyze the effect of automation on economic growth and inequality in an R&D-based growth model with two types of labor: highskilled labor that is complementary to machines and low-skilled labor that is a substitute for machines. The model predicts that innovationdriven growth leads to increasing automation, an increasing skill premium, an increasing population share of graduates, increasing income and wealth inequality, a declining labor share, and (in an extension of the basic model) increasing unemployment. In contrast to Pikettys famous claim that faster economic growth reduces inequality, our theory predicts that faster economic growth promotes inequality.
The size of the middle class and educational outcomes : theory and evidence from the Indian subcontinent
(2018) Seiffert, Sebastian; Prettner, Klaus
This paper proposes a stylised model to derive the effect of a sizeable middle class on average educational outcomes. Under reasonable assumptions, the model predicts that the spending share on education increases if the middle class becomes larger such that the size of the middle class has a positive impact on education. We test the relationship empirically by using village/neighbourhood level data from Indian household surveys. To tackle the issue of potential endogeneity of the middle class share of the population, we propose a novel instrument that relies on the fraction of the population belonging to the third (middle) caste (“sudra”). Using this IV strategy, our empirical results support a positive effect of a larger middle class on educational outcomes. Furthermore, we show that the share of the middle class is a more important determinant of female education than male education and that the effect of the middle class on education is more pronounced in rural areas.
Three essays on wage inequality in Germany : the impact of automation, migration and the minimum wage
(2023) Schmid, Ramona Elisabeth; Beißinger, Thomas
Economic inequality has increased in the majority of countries worldwide over the last three decades and is highly present in public discussion, political debate and scientific research. Due to the large number and complexity of driving forces behind changes in wage inequality, this cumulative dissertation focuses on three challenges of the German labour market. The first paper addresses the question to which extent automation and robotization impact wage inequality in the manufacturing sector in Germany between 1996 and 2017. Applying decomposition analyses along the entire wage distribution, driving factors behind changes in wage inequality are identified. On the basis of administrative data and a new introduced measure of automation threat, which combines occupation- and requirement-specific scores of automation risk with yearly sector-specific robot densities, the study provides new evidence to existing literature. Besides the traditional factors education and age, the detailed decomposition analysis provides evidence that automation threat contributes significantly to rising wage inequality. On the one hand, changes in the composition of the workforce that is exposed to automation and robotization led to significant increases in wage inequality in the German manufacturing sector during the last two decades. On the other hand, evidence of a growing wage dispersion between occupations with low automation threat (especially associated with non-routine tasks) and occupations with high automation threat (especially associated with routine tasks) is revealed. This trend contributes to rising wage inequality as predicted by routine-biased technological change. The second research study presents new evidence on immigrant-native wage differentials in consideration of regional differences between metropolitan and non-metropolitan areas between 2000 and 2019 in Germany. Since gaps in remuneration provide information on the effectiveness of immigration and labour market policies as well as identify the degree of economic integration of foreign workers, the analysis is currently of great importance. Using administrative data, aggregate decomposition results support the hypothesis that the majority of wage differentials can be explained by differences in observed characteristics. However, overall wage differentials at the median exhibit an increasing trend, and on average higher gaps in remuneration are revealed in urban areas. Detailed decomposition analyses show that the effects of explanatory factors not only change over time but the sources of gaps also vary along the wage distribution. Decisive explanatory variables in this context are the practised profession, the economic sector affiliation and labour market experience. Distinguishing between metropolitan and non-metropolitan areas provides evidence that especially differences in educational attainment impact immigrant-native wage gaps in urban areas. The third paper evaluates the effects of the introduced national minimum wage in 2015 on the gender wage gap in Germany. Being confronted with a low-wage sector of considerable extent and comparably high wage differentials between men and women, this study on Germany provides necessary new insights in this area of research. On the basis of administrative data and counterfactual difference-in-differences analyses significant decreases of wage gaps between men and women that can be traced back to the introduced statutory wage floor are revealed. Especially at the lowest observed wage level and in the East of Germany the highest decreases are observable. The analysis, differentiated by educational level, age and occupational activity, provides detailed information on the effectiveness of the wage floor for different target groups. In particular, at lower wage levels for the least educated and middle aged workers the introduction of the minimum wage is the driving factor that significantly lowers group-specific gender wage gaps. Counterfactual decomposition analyses finally provide first evidence that in the West of Germany possible discrimination against women at the lowest wages is restricted by the wage floor.
Who are the champions? Inequality, economic freedom and the olympics
(2019) Geloso, Vincent; Kufenko, Vadim
Does a countrys level of inequality affect its ability to win Olympic medals? If it does, is it conditional on institutional factors? We argue that the ability of economically free societies to win medals will not be affected by inequality. In these societies, institutions generate incentives to invest in the talent pool of individuals at the bottom of the income distribution (people who are otherwise constrained in the ability to expend resources on athletic training). These effects cancel out those of inequality. In unfree societies, the incentives that promote investments in skills across the income distribution are weaker. Consequently, the effects of inequality on the ability to win are stronger. Using the Olympics of 2012 and 2016 in combination with the Economic Freedom of the World Index, we find that inequality only matters in determining medal numbers for unfree countries. We link these results to the debates on inequality.
