GROWTH AND WELFARE EFFECTS OF WORLD MIGRATION

Using a two‐bloc endogenous growth model calibrated to two generic sending and receiving countries of equal size, we assess the growth and welfare impact of world migration flows of different skill compositions. The sending country (East) has a lower total factor productivity and a lower endowment of skilled labour. Migration can induce two growth‐enhancing effects: an efficiency effect from the more efficient use of labour in the receiving country (West) and a sectoral reallocation effect from a fall in the host country skilled–unskilled wage rates. Despite growth gains, there are both winners (migrants, the representative Western non‐migrant household) and losers (the representative Eastern household remaining). Remittances can see the latter group joining the winners.     

Unbalanced growth and health care expenditure

Baumol's model of unbalanced growth implies that health care expenditure (HCE) is driven by wage increases in excess of productivity growth. However, it remains unclear whether the HCE in developing countries is affected by the same factor. This paper tests this hypothesis by using China provincial panel data. We show that HCE grows more rapidly if economy‐wide wage growth exceeds productivity growth in China. The results are robust to the use of housing price as an instrumental variable for the economy‐wide nominal wage and the inclusion of real GDP growth, demographic structure, government deficit, pollution emissions and health sector quality as control variables. Furthermore, our findings show that Baumol's cost disease plays a more important role in the less economically developed western regions in which the rural–urban migration is less pronounced.     

Economic growth, skill-biased technical change and wage inequality: A model and estimations for the US and Europe

In recent literature skill-biased technical change has been viewed as a major cause for wage inequality. Some modelling and presentation of stylized facts have been undertaken for US time series data. A preliminary study of wage inequality in a model with knowledge as input in an aggregate production function has been presented by Riddell and Romer [General Purpose Technologies and Economic Growth, 1998, MIT Press]. Although some important forces determining wage inequality are widely accepted we know little about the quantitative impact of each source and differences across countries. We present a growth model of the Romer type with innovation-based technical change and two skill groups where the growth of knowledge, the relative supply of the two skill groups, externalities and substitution effects among the two groups are the driving forces for wage inequality. We undertake estimates for US time series data and contrast those estimates with results from some European countries. In particular, we compare parameter estimations for US and German time series data. The paper concludes that there is less wage inequality across skills in Europe in contrast to the US on the macroeconomic level. But, considering disaggregated data we observe some increases in inequality for Germany, too. Although our model reveals important variables for the explanation of wage inequality there may, however, also be other factors, such as trade unions, which have impacted the wage spread.     

Wage Assimilation of Foreigners: Which Factors Close the Gap? Evidence From Germany

This study analyzes the development of the wages of male foreign workers from all important sending countries across time using longitudinal employment register data. A cohort analysis of the individuals entering the German labor market in the years 1999 to 2001 indicates that the raw wage gap of migrants compared to native Germans decreases by 14 log percentage points in the first eight years. The results of a decomposition method based on fixed effects regression models give evidence that this wage adjustment is mostly due to time‐varying observable characteristics. Selective return migration, and the trend effects play no role for the aggregate. We find that wage assimilation happens mainly through three channels: first, through the accumulation of firm‐specific human capital, which explains approximately 40 percent; second, search gains are approximately the same order of magnitude; and third, the accumulation of general human capital explains one‐fifth of the assimilation. We further demonstrate that the importance of these channels differs substantially by the origin groups.     

Australian Capital City Real House Prices, 1979–1993

Real house prices have increased by 35 per cent in Australian capital cities during the last 15 years, with Brisbane, Canberra, and Sydney experiencing rises of 48 to 61 per cent and Adelaide, Melbourne and Perth having increases of 20 per cent or less. This article estimates a single model for the six cities to explain the divergent real price behaviour over time and space. It is concluded that the fundamental forces driving real house prices are the growth rate in real wage income (primarily due to employment growth) and the growth in population caused by net overseas migration.     

Out of Africa? Using the Past to Project African Emigration Pressure in the Future

The paper uses analysis of the mass emigration from poor Europe in the late nineteenth century to project the future mass emigration potential from Africa, especially to the economically more mature Mediterranean economies. The economic and demographic fundamentals driving both experiences are likely to be the same, but their magnitudes are likely to be far bigger in the African case over the next few decades. Efforts to restrict the migration and to seal porous borders may be partially successful; but, if so, they are certain to create unpleasant side–effects. European restrictions will create a greater share of illegals and thus greater absorption problems in recipient nations: European restrictions will create more poverty in African sending regions. And European restrictions will create considerable diplomatic problems between the two regions.     

Labor Mobility and East Asian Integration

East Asian economic integration is commonly analyzed in the context of trade in goods and services and capital flows, while labor flows have been very much neglected. Yet labor flows in the region are rapidly growing, given the diversity in levels of economic development, employment opportunities and wage levels, and the existence of labor surplus and deficit countries. Labor migration poses more benefits than costs for both sending and receiving countries, but there are more sensitivities toward labor flows than trade and capital flows. The characteristics and government policies are different for the unskilled and semiskilled foreign workers and for the professionals and highly skilled. Regional cooperation among countries is needed to manage the flows, reduce the incidence of illegal and undocumented workers, reduce the transaction costs of migration, and protect the rights of these workers.     

International Factor Mobility,Wages and Prices

This paper analyzes the joint influence of migration inflows and outward foreign direct investment (FDI) on wage bargaining. Labor migration and offshoring supported by FDI affect wage deals by changing the outside options of workers and firms. Unemployed workers may find alternative jobs either in the legal or in the illegal labor markets. Wages in this latter case are highly affected by migrants crowding this segment more than any other market. Firms may have the option of moving production partly or entirely to foreign low‐cost countries. A wage curve is designed theoretically, reflecting cross‐border labor and capital mobility, and estimated on panel data for 13 European countries over the period 1995–2013. The theoretical predictions of a joint negative effect on wages of FDI outflows and labor migration inflows are confirmed with some novel results.     

Wage Inequality and Human Capital Formation under Migration Possibilities

I examine the problem in the relationship between wage inequality and human capital formation under migration possibilities. Unlike previous analyses, I incorporate the education market and the education price into the analysis, and assume that workers bear the pecuniary cost for receiving education. Given such an assumption, migration possibilities do not necessarily increase education demand since the larger demand for education raises the education price and lowers the net return on education. By modelling an economy where workers in the home country (the labour‐sending country) comprise skilled and unskilled workers and they can migrate to the foreign country (the labour‐receiving country), I show that brain gain and brain drain occur simultaneously in the home country. In particular, if wage inequality is larger in the foreign country than in the home country, skilled workers experience brain gain and unskilled workers experience brain drain in the home country. On the other hand, if wage inequality is sufficiently larger in the home country, brain drain occurs in skilled workers and brain gain in unskilled workers.     

The Missing Link: China's Contracted Engineering Projects in Africa

This paper examines the driving forces of China's contracted engineering projects in Africa. Using data on contracted engineering projects in 52 African countries over the period 1991–2010, three groups of hypotheses are tested: (1) economic motives; (2) political ties between China and Africa; and (3) host country characteristics. We find that countries get more projects if they have large market potential and are political allies of China. Our results also suggest that Forums on China–Africa Cooperation promote projects in Africa. In contrast, host country characteristics are hardly related to the amount of engineering projects received.     

Public or Private Sector Wage Leadership? An International Perspective*

Whether a government acts as a wage leader, placing pressure on private‐sector wages (more open to competition), or whether it plays a passive role and merely follows wage negotiations in the private sector, there are important implications for macroeconomic development, particularly in small open economies and/or countries that are members of a monetary union, such as those of the European Monetary Union. With the notable exception of the case of Sweden, opinion on this issue is still divided. In this paper, we look at public‐ and private‐sector wage interactions from an international perspective (18 OECD countries). We focus on the causal two‐way relationship between public and private wage setting, confirming that the private sector, on the whole, appears to have a stronger influence on the public sector, rather than vice versa. However, we also find evidence of feedback effects from public wage setting, which affect private‐sector wages in a number of countries. When the private sector takes the lead on wages, there are few feedback effects from the public sector, while public wage leadership is typically accompanied by private‐sector feedback effects.     

Labour migration in the Indian states and the Todarian hypothesis

The model of migration in developing countries developed by Todaro and others, in which the driving force behind rural-urban migration is the wage differential between urban and rural areas is examined using 1971 and 1981 census data for the states of India. The results do not provide any evidence supporting this model, which the author suggests is not surprising given the imperfect product and factor markets prevailing in India.     

The Effect of Corruption on Investment Growth: Evidence from Firms in Latin America,Sub‐Saharan Africa,and Transition Countries*

Most of the empirical studies that analyze the impact of corruption on investment have three common features: they employ country‐level data on investment, corruption is measured at the country level, and data for countries from several regions are pooled together. This paper uses firm‐level data on investment and measures corruption at the firm and country level, and allows the effect of corruption to vary by region. Our dependent variable is firms' investment growth and we employ six measures of corruption from four different sources—two firm‐level measures and four country‐level measures. We find that the effect of corruption on investments varies significantly across regions: corruption has a negative and significant effect on investment growth for firms in Transition countries but has no significant impact for firms in Latin America and Sub‐Saharan Africa. Furthermore, for Transition countries, corruption is the most important determinant of investment.     

Efficiency and distributional implications of global restrictions on labour mobility: calculations and policy implications

This paper sets forth a procedure for calculating the annual efficiency gains from alternative changes in existing international immigration restrictions and evaluates the impact of wage rate changes on nonmigrating labor. Data on US gross national product (GNP)/capita across countries are used to infer differences in the marginal productivity both between countries and across major world trading areas. The method assumes that the worldwide labor supply is fixed, that full employment occurs in all regions, and that differences in labor's marginal product across regions arise because of barriers to inward mobility of labor in high-wage countries. When these barriers are removed, labor is assumed to be reallocated and efficiency gains occur. Results of the calculations suggest large gains from the removal of global immigration controls which, in most cases, exceed existing worldwide GNP generated in the presence of labor mobility restrictions. A large portion of the gain is accounted for by labor migration between the aggregated rich and poor countries. Over 40% of the total potential gain is realized when only 10% of the wage differential is eliminated, suggesting that small changes in global migration restrictions have large marginal effects. Wage rates increase in labor-losing regions and decline in labor-receiving regions, dramatizing the incentives for labor unions in high-wage countries to oppose liberalization of immigration restrictions. These results suggest large potential worldwide efficiency gains from a move toward an international labor market free of immigration controls. This issue may be far more important to the North-South debate than a focus on initiatives such as commodity price stabilization, relaxation of trade protection, or increased aid flows.     

Attitudes about EU expansion and zero‐sum thinking

EU expansion can be seen as a positive‐sum process benefiting all countries by creating larger markets that stimulate more productive economies through increased specialization and economies of scale, implying that the general public in all countries should favour expansion. Contrarily, expansion can be perceived as zero‐sum. Capital and production relocate from higher to lower wage regions while labour does the opposite, possibly raising unemployment and reducing wages in the higher wage regions. The general public in these countries may come to oppose EU expansion attributing any deterioration in their work situation to the gains of new citizens of the European Union. Analysis of changes in Irish attitudes towards EU expansion in 2002, 2007 and 2009 finds no evidence of a link from lowered economic conditions to increased opposition to EU expansion. The only evidence for zero‐sum thinking is that diminished economic circumstances are associated with increased opposition to immigration, but this is not associated with increased opposition to further EU expansion.     

Trade,aid and migrations: some basic policy issues

The link between trade policy and international migration is explored using data from the United States and Europe. "We conclude that restrictive trade policies in industrialised countries have most likely added to migration pressures. We then turn to the broader question of the effects of income growth in the sending countries on the propensity to migrate. We argue that, in relatively poor countries, an increase in income will be associated with higher migration flows. For middle income countries, however, income growth will lead to lower migrations. In the medium run, therefore, the relationship between development levels, as measured by GDP per capita, and the propensity to migrate follows an inverse-U pattern. Econometric analysis of aggregate migration flows from Southern Europe provides considerable support for such conjecture."     

Coordination versus flexibility in wage formation: a focus on the nominal wage impact of productivity in Germany,Greece, Ireland,Portugal, Spain and the United States

Wage coordination between countries of the European Monetary Union (EMU) aims at aligning nominal wage growth with labour productivity growth at the national level. We analyse the developments in Germany, the EMU’s periphery countries Greece, Ireland, Portugal and Spain along with the United States over the period 1980 to 2010. Apart from the contribution of productivity to nominal wages, we take into account the contributions of prices, unemployment, replacement rates and taxes by means of an econometrically estimated nonlinear equation resulting from a wage bargaining model. We further study the downward rigidities of nominal wages. The findings show that in past times of low productivity, price inflation and reductions in unemployment still put significant upward pressure on nominal wage growth. The periphery countries are far from aligning nominal wage growth with productivity growth. German productivity is a major wage determinant, but surely not the only one. Within the context of a free bargaining process between employers and labour unions, policy-makers can effectively use the replacement rate to steer the nominal wages outcome.     

Looking for the workforce: the elderly,discouraged workers,minorities, and students in the Baltic labour markets

This paper looks at the evolution of the labour markets in Estonia, Latvia, and Lithuania since the beginning of transition until 2003, with a particular focus on labour force participation. How did labour supply in the Baltic countries respond to changes in minimum wages, unemployment benefits and retirement regulation? Do the marked differences in labour market policies between the countries result in different patterns of participation? What are the obstacles to and driving forces of participation? We find that relative contribution of participation and demographic trends to the dynamics of the labour force varied substantially both over the years and across the three countries. Participation, in turn, has been shaped by sometimes complicated interactions between schooling decisions of the youth, retirement, policy changes, and external shocks. Resulting differences in trends and patterns are quite substantial, indicating that there is a room for increasing participation in each of the countries. Panel data analysis of determinants of participation and discouragement based on labour force survey data suggests that increasing after-tax real minimum wage has significant positive effects on participation and reduces discouragement in Lithuania. In Estonia, by contrast, a positive effect of minimum wage on participation is found only for teenagers of both genders and for young males. We do not find any evidence that partner’s wage has a negative effect on participation. Ethnic minorities, especially females, in all three Baltic countries are less likely to be in the labour force, other things equal.     

Pane e Cioccolata: The Impact of Native Attitudes on Return Migration

This paper addresses the link between native attitudes and return migration. We exploit the variation in xenophobia using information on media consumption by migrants in Italy. A widely documented crime provides a quasi‐experimental setting to identify the impact of Italian attitudes on migrants’ settlement intentions. Our results suggest a significant effect of anti‐immigrant attitudes on the intended duration of stay in the host country. The impact is more pronounced for low‐skilled migrants, which has consequences for how migration affects the long‐run convergence between sending and destination countries.     

Growth and convergence in South–South integration areas: An empirical analysis

Until recently, it has been argued in economic theory that regional integration and trade agreements among developing countries may achieve negative growth effects. This study tests empirically the effects of such South–South agreements on growth and convergence. All three world regions in question are considered: South America, Southeast Asia, and Sub‐Saharan Africa. A comprehensive panel data analysis is conducted that distinguishes between the problems of testing for stronger growth and accelerated convergence, respectively. The data indicate that the considered South–South agreements promote both.
