The brain drain and the world distribution of income

Skilled emigration (or brain drain) from developing to developed countries is becoming the dominant pattern of international migration today. Such migration is likely to affect the world distribution of income both directly, through the mobility of people, and indirectly, as the prospect of migration affects the rate of return to education in both the sending and receiving economies. This migration pattern will therefore affect human capital accumulation and fertility decisions in both the sending and receiving economies. This paper analyzes these effects in a dynamic two country model of the world economy where agents in both countries make optimal fertility and human capital decisions. The implications of the analysis for the world distribution of income are derived in the light of recent empirical findings of the brain drain literature. The analysis shows that the current trend towards predominantly skilled emigration from poor to rich countries may in the long run increase inequality in the world distribution of income as relatively poor countries grow large in terms of population. In the short run however, it is possible for world inequality to fall due to rises in GDP per capita in large developing economies with sufficiently low skilled emigration rates.     

Going NUTS: The effect of EU Structural Funds on regional performance

The European Union (EU) provides grants to disadvantaged regions of member states to allow them to catch up with the EU average. Under the Objective 1 scheme, NUTS2 regions with a per capita GDP level below 75% of the EU average qualify for structural funds transfers from the central EU budget. This rule gives rise to a regression-discontinuity design that exploits the discrete jump in the probability of EU transfer receipt at the 75% threshold for identification of causal effects of Objective 1 treatment on outcome such as economic growth of EU regions. We find positive per capita GDP growth effects of Objective 1 transfers, but no employment growth effects.     

IMMIGRATION UNEMPLOYMENT RELATIONSHIP: THE EVIDENCE FROM CANADA*

This paper examines the relationship between unemployment and immigration in Canada. The bi‐directional causality test finds no evidence of a significant effect of Canadian immigration on unemployment. Cointegration tests indicate that there is no observed increase in aggregate unemployment due to immigration in the long run. The results from the causality test based on the vector error correction model confirm that, in the short run, past unemployment does cause (less) immigration but not vice versa. There is also a long‐run positive relationship among per‐capita GDP, immigration rate and real wages. The results indicate that, in the short‐run, more immigration is possibly associated with attractive Canadian immigration policies, and in the long‐run, as the labour market adjusts, Canadian‐born workers are likely to benefit from increased migration.     

Productivity and per capita GDP growth: The role of the forgotten factors

Average hourly productivity has often been used to draw conclusions on long run per capita GDP growth, based on the assumption of full utilization of labor resources. In this paper, we argue that a failure to recognize the potential significant wedges among the two variables - even in the long run - can be misleading. By applying both time series and panel cointegration techniques on data on 19 OECD countries, we fail to reject the hypothesis of the absence of a long run common stochastic trend among the two variables in the period 1980-2005. Furthermore, we apply a simple decomposition of GDP growth into five variables, including some related to the supply-side and demographics, so to verify the single contributions to income growth and variance over our period of interest. We conclude that variables that have been so far absent in the growth literature indeed have a non-negligible role in explaining the dynamics of long run per capita GDP growth. In particular, these “forgotten factors” (that we identify with the employment and the activity rates and a demographic ratio) matter more in better performing economies, where we also highlight that productivity has been less important in determining GDP growth than in relatively bad performers.     

Temporal causality and the dynamics of democracy,emigration and real income in Fiji

This study is the first to explore temporal causality between democracy, emigration and real income in Fiji within a multivariate cointegration model. We find three long run relationships between democracy, emigration and real income. In the long run there is evidence that migration and democracy Granger cause real GDP in Fiji; real GDP and democracy Granger cause migration from Fiji and that real GDP and migration Granger cause democracy in Fiji. In the short run we find unidirectional Granger causality running from migration to real GDP and from democracy to real GDP, but neutrality between democracy and migration in the short run. We also extend the analysis to examine the degree of exogeneity of the variables beyond the sample period through considering the decomposition of variance and impulse response functions.     

Selective Immigration Policies and Wages Inequality

We quantify the overall impact of immigration on native wages in France from 1990 to 2010. Our short‐run simulations indicate that immigration has decreased native wages by 0.6%. We find on average no impact of immigration on wages in the long run. However, we show that the long‐run effects of immigration on wages are detrimental to high‐skilled native workers and benefits to low‐skilled native workers. Our structural estimation allows us to evaluate the impact of “selective” migration policies. In particular, we find that selective immigration policies toward highly educated workers reduce the wage dispersion of French native workers.     

A permanent effect of temporary immigration on economic growth

Immigration can help to lessen the burden of ageing for the welfare states of most Western economies. To show this, we develop a decomposition framework for Gross Domestic Product (GDP) per capita which deals with the impact of both ageing and immigration on economic growth. Using a Vector Error Correction Model (VECM) for the Netherlands during 1973 to 2009, we demonstrate the empirical relevance of some crucial interactions between elements of that decomposition. The conclusion is that even temporary immigration may help to alleviate the ageing problem through a positive long-term contribution to employment, wages and GDP per capita, as long as the immigrants are able to participate in the labour force in tandem with the native population. Unfavourable short-term effects should be avoided through a gradual phasing in of immigration policies.     

Long-term growth scenarios for Poland to 2025

One of the major long-run problems facing the economies in transition is whether their productive potential will achieve the average per capita levels typical of the EU member countries in the foreseeable future. If so, what possible measures should be taken to reach this end? This issue applies in particular to Poland with a GDP per capita being roughly a half of what it is in Greece or Portugal. An attempt to give an answer to these questions is given in the paper by means of simulations based on the W8-D model for the Polish economy. The model served as a tool to elaborate a long-term forecast and run alternative policy scenarios to cover realistic boundaries of the future economic development of Poland up to the year 2025.     

Technology spillover effects within Spanish communities

The article uses panel data for the period 1990–2010 to estimate technology spillover effects on 17 Spanish communities. Accounting for nonstationarity and cointegration, we use the dynamic OLS estimator to estimate the impact of domestic and non-domestic R&;D capital stock on labour productivity of Spanish communities, taking into account trade-, migration- and foreign direct investment (FDI)-related technology diffusion channels. We find significant trade-related spillover effects within Spanish communities and from EU countries. On average, an increase in the non-domestic R&;D stock of 1% increases their labour productivity between 0.02% and 0.12% if related to bilateral trade pattern. Moreover, migration within Spanish communities has a negative impact ranging between ?0.07% and ?0.16% on labour productivity as the impact of inward migration is dominated by outward migration. There is no robust impact from FDI inflows of OECD countries in general or EU countries in particular. Finally, the domestic R&;D stock, physical capital and human capital are shown to be significant drivers for labour productivity in Spain no matter if non-domestic (local or foreign) spillover effects are trade-, migration- or FDI-related.     

Structural Operations and Net Migration Across European Union Member Countries

This paper analyzes the effects of international transfers to finance infrastructure on net migration flows among countries within the EU. A new economic geography model is employed with common pool financed infrastructure investments to derive a set of empirically testable hypotheses about the effects of transfer payments to finance infrastructure investments on migration. A significant effect of structural fund expenditures is identified on the bilateral net migration of workers among the EU member countries. On average, a one percentage point increase in the expenditures on structural funds (in per cent of gross domestic product (GDP)) leads to a reduction in the measure of bilateral net migration by about 0.4–0.8%.     

Population and Economic Growth Under Different Growth Engines

Using a growth model with physical capital accumulation, human capital investment and horizontal R&D activity, this paper proposes an alternative channel through which an increase in the population growth rate may yield a non‐uniform (i.e., a positive, negative, or neutral) impact on the long‐run growth rate of per‐capita GDP, as available empirical evidence seems mostly to suggest. The proposed mechanism relies on the nature of the process of economic growth (whether it is fully or semi‐endogenous), and the peculiar engine(s) driving economic growth (human capital investment, R&D activity, or both). The model also explains why in the long term the association between population growth and productivity growth may ultimately be negative when R&D is an engine of economic growth.     

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.     

1990—2010年中国人口预期寿命与人均GDP的相关关系及其变化特征

预期寿命是反映人口寿命水平的重要指标,人均GDP是反映经济发展的重要指标。采用相关分析和回归分析对中国1990—2010年市域、县域两个尺度的预期寿命与人均GDP的关系进行分析,结果表明:人均GDP对预期寿命具有显著正向影响,但累积影响强于即时影响;人均GDP超过3000~5000元后,其对预期寿命的影响开始出现边际递减效应;人均GDP对预期寿命的影响强度在空间分布上自东向西增强。由于经济相对发达的东部地区人均GDP对预期寿命的贡献率要小于经济相对落后的西部地区,因此,今后东部地区应通过完善社会保障、优化卫生资源配置、倡导健康生活方式等途径进一步提高预期寿命,西部地区则应大力发展区域经济,努力提高生活水平,以尽快缩小与东部地区预期寿命的差距。     

The impact of the credit crisis on poor developing countries: Growth,worker remittances,accumulation and migration

We show that the credit crisis of OECD countries has a negative impact on the growth of the world economy according to an error-correction model including China and Australia. This causes negative growth effects in poor developing countries. The reduced growth has a direct or indirect impact on the convergence issue, aid, remittances, labour force growth, investment and savings, net foreign debt, migration, tax revenues, public expenditure on education and literacy. We estimate dynamic equations of all these variables using dynamic panel data methods for a panel of countries with per capita income below $1200 (2000). The estimated equations are then integrated to a dynamic system of thirteen equations for thirteen variables that allows for highly non-linear baseline simulations for these open economies. Then we analyze the effects of transitional shocks as predicted by the international organizations for the OECD and world growth for 2008 and 2009. Whereas growth rates return to the baseline scenario until 2013 with overshooting for China and Australia, the level of the GDP per capita shows permanent effects, which are positive only for China. In the poor countries, investment, remittances, savings, tax revenues, public expenditure on education, all as a share of GDP as well as literacy and the GDP per capita, are reduced compared to the baseline until 2087 where our analysis ends. Investment, emigration and labour force growth start returning to baseline values between 2013 and 2017. GDP per capita and tax revenues start returning to baseline around 2040. Education variables do not return to baseline without additional effort.     

Health spending in Italy: The impact of immigrants

The welfare impact of immigration is a highly debated issue especially for countries on the external borders of the European Union. This paper studies how immigrants affect public health expenditure across Italian regions during the period 2003–2016 using NUTS II level data. Identification strategy is based on shift–share instruments, which are made robust to pull factors that might attract immigrants in Italy and to internal migration of natives. We find that a 1 percentage point increase in immigrants over total resident population leads to a decrease in public health expenditure per capita by about 3.8% (i.e. around 69 euro per capita). Among possible channels, we find no support for any crowding out effect from public to private health services by natives due to increasing immigration or for any role played by different levels of efficiency across regional health systems. Our results are driven by immigrants' demographic structure: they are mostly males and younger workers that call for less health spending, according to a positive selection mechanism. Moreover, linguistic barriers contribute to limiting the immigrants' reliance on public healthcare, which is confirmed also by the use of the European Health Interview Survey microdata.     

An empirical analysis of the relationship between economic development and population growth in China

China has experienced a dramatic demographic transition since the latter half of the twentieth century, and thus, assessing the global economic implications is an important issue. This article uses time-series data on China to estimate the determinants of gross domestic product (GDP) per capita. According to the results of the presented co-integration analysis, population has a significantly negative impact on GDP per capita, while savings rate, total factor productivity and degree of industrialization have significantly positive impacts on GDP per capita. These results suggest that the share of the working-age population relative to the total population does not have a strong influence on GDP per capita. Therefore, the contribution of the working-age population to economic growth might not be as large as previously assumed. It is also possible that an increase in savings, remarkable industrialization and rapid technological progress have all stimulated economic growth in China greatly.     

The welfare impact of migration with endogenous cross-border movement: An application to the European Union

In this paper, I examine the welfare impact of migration in a general equilibrium model with endogenous worker location choice. My framework incorporates labor productivity differences across countries, worker heterogeneity in productivity across skill and nativity types, as well as country-pair specific costs of migration. In a series of experiments, I predict the migration response of workers to an expansion or contraction in the number of European Union (EU) member countries. For the case of the United Kingdom (U.K.) leaving the EU, commonly referred to as Brexit, low skilled native-born U.K. workers suffer a drop-in income, whereas high skilled workers experience an increase. This result is driven, in part, by an increase in high skilled immigration to the U.K. from outside the EU, which helps to dampen the loss in income of low skilled workers.     

Persistence of cities: Evidence from China

Using data from the Qing dynasty, we investigate the long‐run impact of early development on today's living standards in China. We use city‐level population density in 1776 as a measure of early economic prosperity, and examine how it is associated with today's development indicators such as the average night light density, GDP per capita, average years of schooling, and trade openness. We find that cities which were more prosperous during the Qing dynasty are now also brighter, richer, more educated, and more open.     

Testing convergence of European regions: A semiparametric approach

We provide a reappraisal of income convergence across European regions over the last two decades by using a semiparametric partially linear model to approximate the relationship between the average growth rate of GDP per capita and the initial GDP per capita. Estimation results point out both country heterogeneity and non-linearity in the convergence process. The findings suggest that low income regions, in particular those from new adhesion countries, diverge while medium income regions converge and that there is no evidence of convergence for high income regions.     

Structural Change,Urban Congestion,and the End of Growth

This paper develops a two‐sector R&D‐based growth model with congestion effects from increasing urban population density. We show that endogenous technological progress causes structural change if there are positive productivity spillovers from the modern to the traditional sector and Engel's law holds. In turn, urban congestion effects cause a productivity slowdown in the modern sector. Eventually, economic growth may cease in the long‐run. We also show that land dilution by a larger workforce may give rise to negative scale effects on (GDP) per capita.
