A utility function based approach towards the modeling of migration in village equilibrium models
(2010) Kleinwechter, Ulrich
Village equilibrium models are computable general equilibrium (CGE) implementations of agricultural household models in a village equilibrium framework which have the salient feature of being able to capture general equilibrium effects arising at the level of rural communities. Due to the important role migration plays for livelihoods in developing countries, the approach has been successfully applied to analyze aspects related to migration and village economies. However, the depiction of migration in village equilibrium models is not carried out in a way that captures interactions between migration and household consumption demand while at the same time allows for an endogenous adjustment of the level of migration by the households themselves. Furthermore, approaches to modeling migration are purely demand side oriented. Supply side factors, such as differences between households, which may influence household responses to changes in incentives to migrate, cannot be accommodated in a theoretically convincing manner. To address these issues, a nonseparable household model with endogenous migration decisions and feedback to the consumption sphere is proposed as the theoretical foundation for a village equilibrium model. A composite utility function captures utility which accrues to the household through per capita household consumption of goods and leisure, on the one hand, and utility stemming directly from participation in different activities by the household including migration, on the other hand. It is shown that the allocation of labor among different activities is governed by the size of marginal returns to labor in terms of market returns, changes in household demand and (dis)utility of labor market participation relative to the household shadow wage. The practical implementation of the theoretical framework is achieved by the derivation of two independent demand systems from the composite utility function. A per capita linear expenditure system is proposed to depict household consumption demand. The allocation of labor to migration is assumed to follow a factor demand specification using power functions which translate utility considerations made by the household into imperfectly elastic responses to changes in incentives for participation in the labor market.
Can international migration ever be made a Pareto improvement?
(2009) Felbermayr, Gabriel; Kohler, Wilhelm
We argue that compensating losers is more difficult for immigration than for trade and capital movements. While a tax-cum-subsidy mechanism allows the government to turn the gains from trade into a Pareto improvement, the same is not true for the so-called immigration surplus, if the redistributive mechanism is not allowed to discriminate against migrants. We discuss policy conclusions to be drawn from this fundamental asymmetry between migration and other forms of globalization.
Does immigration boost per capita income?
(2008) Sala, Davide; Felbermayr, Gabriel J.; Hiller, Sanne
Using a cross-section of countries, we adapt Frankel and Romer's (1999) IV strategy to international labor mobility. Controlling for institutional quality, trade, and financial openness, we establish a robust and non-negative causal effect of immigration on real percapita income.
Ethnic networks, information, and international trade : revisiting the evidence
(2009) Felbermayr, Gabriel; Jung, Benjamin; Toubal, Farid
Influential empirical work by Rauch and Trindade (REStat, 2002) finds that Chinese ethnic networks of the magnitude observed in Southeast Asia increase bilateral trade by at least 60%. We argue that this estimate is upward biased due to omitted variable bias. Moreover, it is partly related to a preference effect rather than to enforcement and/or the availability of information. Applying a theory-based gravity model to ethnicity data for 1980 and 1990, and focusing on pure network effects, we find that the Chinese network leads to a more modest amount of trade creation of about 15%. Using new data on bilateral stocks of migrants from the World Bank for the year of 2000, we extend the analysis to all potential ethnic networks. We find, i.a., evidence for a Polish, a Turkish, a Mexican, or an Indian network. While confirming the existence of a Chinese network, its trade creating potential is dwarfed by other ethnic networks.
International student mobility, student exchange programs, and migration : evidence from gravity estimations
(2022) Reczkowski, Isabella; Felbermayr, Gabriel
The thesis is dedicated to the empirical investigation of international student mobility and is divided into eight chapters. The introductory chapter 1 describes the motivation for the thesis and provides a brief overview of the current literature and the gap that this dissertation fills. Chapter 2 discusses the rationales for cross-border education, describing the four approaches of the OECD (2004) for international student mobility: the mutual understanding approach, the skilled migration approach, the revenue-generating approach, and the capacity building approach. The chapter then discusses the challenges resulting from international student mobility. Besides the brain drain and brain gain phenomenon that occurs when international students decide to work abroad, international student mobility raises the question of how to provide equal access to higher education and ensure the same level of quality and accreditation across the board. Furthermore, the chapter includes a detailed discussion on the challenges that arise when higher education is mainly publicly financed in a world where students and graduates are mobile. This is mainly the case in Europe, whereas students in other countries are accustomed to paying for higher education. Chapter 3 goes on to describe the data on international student mobility used in this work. Since data for years prior to 1998 are only available from printed UNESCO Statistical Yearbooks, this dissertation has constructed a new database entering the data manually for the years 1970 to 1997 for 29 destination countries and almost all countries of origin. The chapter demonstrates that student mobility increased sharply. Starting with an average number of roughly 460 thousand students in the first period covering the years 1970 to 1974, the number grew by a factor of about 8 to roughly 3.7 million students in the last period covering the years 2010 to 2015. This number is strongly concentrated on a few destination and origin countries: while the concentration in the destination countries decreased over the decades which were analyzed, with the top five countries accounting for about 77 percent in the 1970s and 50 percent in the period 2000 to 2015, the concentration in the origin countries increased from about 23 to 33 percent. The decreasing concentration of destination countries demonstrates the strong competition among these countries trying to attract international students. In order to better understand this concentration, chapter 4 provides a descriptive analysis of destination and origin countries. Apart from the five main Anglo-Saxon destination countries–the United States, the United Kingdom, Australia, Canada, and New Zealand–the European countries France and Germany have always been among the most important destination countries since 1970. Furthermore, Russia and Japan have played an important role and some Asian, European, and Arab countries have also recently emerged as important destination countries. The countries that send the most students abroad are Asia-Pacific Rim countries followed by European countries. With this in mind, three groups of countries have had a major impact on student mobility: Europe, Asia-Pacific countries, and Anglo-Saxon countries. In contrast to the other regions, student mobility in Europe is supported by policy-makers and instruments which are supported by large investments. Therefore, this work strives to investigate the effects of the two famous European programs which were introduced to promote student mobility: the student exchange program Erasmus that was launched in 1987, and the Bologna Process that began in 1999. Chapter 5 strives to test the hypothesis of whether the student exchange program Erasmus increases student mobility between the member countries. The chapter uses data on international student mobility for the years 1999 to 2015 obtained from the electronic UNESCO database for 155 host and 187 origin countries which are merged with a dummy variable on joint membership in the Erasmus program. Using these panel data in a theory-grounded gravity model by running fixed effects methods, the chapter finds that student mobility between Erasmus member countries is, on average, about 53 percent higher. To address the causality question, the chapter follows Wooldridge (2002) and performs an F-test for strict exogeneity and finds a positive causal effect on international student mobility. This effect is more stable for the time during and after the economic crisis. Furthermore, student exchange between Erasmus countries seems to occur more in favor of cultural experience and is not based on economic factors. Chapter 6 repeats these estimates controlling additionally for joint membership in the Bologna Process and finds that student mobility between Bologna Process members is, on average, about 50 percent higher. Importantly, both European programs–Erasmus and the Bologna Process–turn out to be significant determinants separately. Estimating the effect for the time before and after the establishment of the European Higher Education Area (EHEA) shows that the impact is higher and more stable since the EHEA was established in 2010. These findings suggest that the Erasmus program and the Bologna Process have fulfilled their goals of increasing student mobility and, therefore, justify their budget. Since the skilled migration approach argues that countries attract international students hoping that they stay in the country of studies afterwards and increase the stock of highly-skilled workers, chapter 7 investigates the question: to what extent do countries that attract foreign students benefit from an increased stock of educated foreign workers? Using information from the UNESCO Statistical Yearbooks, the chapter constructs a new panel database of bilateral international student mobility for 150 origin countries, 23 host countries for the years 1970 to 2000. These data are matched with information on bilateral stocks of international migrants by educational attainment from Docquier et al. (2008), available for 1990 and 2000. Running theory-founded gravity models by conditional fixed effects Poisson Pseudo Maximum Likelihood methods, this chapter finds that, on average, an increase of students by 10 percent increases the stock of tertiary educated workers in host countries by about 0.9 percent. That average effect is, however, entirely driven by Anglo-Saxon countries. On average, the results imply a student retention rate of about 70 percent. These findings suggest that the costs of educating foreign students are at least partially offset by increased availability of foreign talent. Finally, the last chapter 8 concludes.
Migration and innovation : a survey
(2013) Pyka, Andreas; Rashidi, Sheida
In a world characterized by competition on a global scale, persistent structural change driven by innovation and aging societies in industrialized economies, also the competition for the best talents on the labour markets becomes global and more intensive. Therefore it is not surprising that old-fashioned brain drain explanations for migration are no longer convincing. In the knowledge-based economies of the 21st centuries the ideas of brain circulation and international (diaspora) innovation networks become prevailing and should guide the design of migration policies. This paper is a survey on the theoretical and empirical approaches which address the important relationship between migration and innovation.
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.
Spatial data analysis in economics
(2020) Jasny, Johannes; Sousa-Poza, Alfonso
Spatial data analysis has become a widely used tool among economists and social scientists. Improved availability of georeferenced social and economic data, a rising interest in data visualisation, spatial pattern recognition, and spatial interactions as well as improved statistical techniques increased the popularity of spatial data analysis techniques. The purpose of this work is to study spatial data analysis techniques and apply those techniques on social and economic issues. This work consists of three articles on applied spatial data analysis in economics. The first article studies the determinants of local supply differences in the market for election gambling machines (EGM). We study, whether a certain social and economic milieu (e.g. high unemployment) is associated with higher EGM supply. The second article studies spillover effects in the EGM market. The article explains why the EGM supply clusters in certain regions which results in “hot spots” with high gambling supply. Article three evaluates the impact of immigration on the voting behaviour in Germany. As an example, we use the 2015/2016 refugee crisis and study how refugee presence affected the regional election outcomes in the 2016 elections in Germany.
Statistischer Überblick der türkischen Migration in Baden-Württemberg und Deutschland
(2012) Kaiser, Micha; Hartmann, Dominik
Diese Arbeit stellt die Eckdaten der türkischen Migration nach Deutschland zusammen. Das erste Kapitel beleuchtet die historischen Meilensteine der Integration, vom Anwerbungsabkommen am 31. Oktober 1961, über das Rückkehrförderungsgesetz 1983 und dem Einbürgerungsgesetz aus dem Jahr 2000. Das zweite Kapitel fasst wesentliche Daten und Fakten über die türkischen Einwanderer in Deutschland - im Vergleich auch zu anderen Migrantengruppen ? zusammen; unter anderem werden dabei Altersstruktur, Bildung und Einbindung in den Arbeitsmarkt analysiert. Im dritten Kapitel wird der Fall Baden-Württemberg näher dargestellt, im vierten kurz auf die Stadt Stuttgart eingegangen. Abschließend werden die positiven und negativen Tendenzen, basierend auf dem zugrundeliegenden Datenmaterial, noch einmal zusammengefasst. Einerseits wird die positive Tendenz vom Gastarbeiter zum Bürger deutlich, andererseits decken die Zahlen nach wie vor bestehende Schwächen deutlich auf. Diese Arbeit soll einen Beitrag dazu leisten, die Vielzahl unterschiedlicher Statistiken zum Thema Deutsch-Türkische Migration prägnant zusammenzufassen und anschaulich darzustellen.
The pro-trade effect of the brain drain : sorting out confounding factors
(2008) Jung, Benjamin; Felbermayr, Gabriel J.
We sort out confounding factors in the empirical link between bilateral migration and trade. Using newly available panel data on developing countries? diaspora to rich OECD nations in a theory-grounded gravity model, we uncover a robust, causal pro-trade effect. Moreover, we do not find evidence in favor of strong differences across education groups.
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.
Three pillars of urbanization : migration, aging, and growth
(2018) Südekum, Jens; Prettner, Klaus; Grafeneder-Weissteiner, Theresa
Economic development in industrialized countries is characterized by rising per capita GDP, increasing life expectancy, and an ever larger share of the population living in cities. We explain this pattern within a regional innovation-driven economic growth model with labor mobility and a demographic structure of overlapping generations. The model shows that there is a natural tendency for core-periphery structures to emerge in modern knowledge-based economies.
Village level impacts of trade reform in China
(2011) Kleinwechter, Ulrich; Grethe, Harald
During the past decades, China has carried out ambitious economic reforms. The reforms have resulted in strong economic growth and considerable reductions in poverty. The current situation, however, is also characterised by rising tensions within the country, caused, among others, by rural-urban and inland-coastal disparities. In this situation, rural-urban migration occupies central stage, both for the livelihoods of rural households and for the outcome of further policy reforms. In this context, trade liberalisation for a number of reasons can be expected to play an important role for the future development of poverty and inequality in the country. Against this background, the present work analyses and assesses the impacts of further trade liberalisation efforts on a rural community in south-western China. Recognising the importance of these issues, emphasis is put on poverty, inequality and rural-urban labour migration. Subject of the analysis is a village located in one of the less developed counties of Guizhou province. Thereby, this village level case study aims not only at shedding light on the impacts of future trade reforms on this particular village, but also has the objective of providing more general insights into the mechanisms which are at work when trade policies are brought down to a local level. The study seeks to promote an enhanced understanding of relevant processes in similar settings, allowing for improved assessments in the field of development oriented trade policy analysis. The objectives of the study are achieved by the application of a village computable general equilibrium model embedded into a macro-microsimulation framework. In this framework, aggregate results from a national level CGE study of unilateral trade liberalisation in China are administered as a policy shock to the village model, which offers a highly disaggregated picture of the village economy and allows for a detailed analysis of the impacts of the reform. The village model which is a CGE representation of the village economy forms the core part of the present study. The households which make up the village community are depicted by six representative household groups, each of them represented by an agricultural household model. The six groups stratify the village population by household demographics and income levels, thus distinguishing the households by their migration behaviour and by relative poverty. Each representative household can carry out up to four productive activities: agriculture, formal and informal local off-farm work as well as migration. Agricultural production is modelled with a nested Leontief-Cobb-Douglas technology. Household consumption is represented by a per-capita LES which includes self-consumption of agricultural output, purchased goods as well as leisure. By incorporating the assumption of a perfectly neoclassical village land market, the model makes a step towards the modelling of land rental transactions which take place within the village. The land market links the households together and creates local general-equilibrium effects which greatly affect the outcome of the policy reform. The salient feature of the village model is a novel approach towards the modelling of the households' labour allocation behaviour, and in particular the migration behaviour. The approach takes into account household preferences towards work in different types of employment as well as feedback links between household migration and consumption demand. This is achieved by the assumption of a composite utility function, which defines the behaviour of each household in the model. The composite utility function consists of a consumption utility function, which captures utility created by commodity consumption, and a labour utility function, which allows to account for the utility or disutility associated with the participation in different types of employment. By considering the disutility arising from certain employment options, the current work offers an important contribution to the methodological development of agricultural household and village equilibrium modelling. It provides a modelling framework, which paves the way for similar applications in different settings and opens an interesting field for future applications, which may also extend to levels of higher regional aggregation. At the same time, the model constitutes a highly valuable tool for the analysis of the migration behaviour of rural households under different policy scenarios along the lines of household demographics and income levels. Thereby, the availability of transparent information on socio-economic characteristics of the household groups, the remittances behaviour as well as the disutility connotations of migration offer great support to such efforts. Not least, it allows deriving theoretically sound hypotheses on the migration behaviour of rural households in different policy situations.
