Migration,community networks and welfare in neoclassical growth models

This paper proposes a Ramsey-Like model of growth with endogenous migration to study the effects of migration networks on the macroeconomy and welfare of hosting economies. In the model, migration is assumed to be made of two different components: a first, forward-looking component in which the rate of net migration depends on the wage gap between countries; a second, backward-looking component in which in-migration depends on the immigration history of the destination country through the formation of immigrant networking. We find that the model exhibits a unique saddle-path steady-state equilibrium and that introducing pro-immigration policies aimed at enhancing community networks have asymmetric impacts on the welfare level of natives and immigrants that hinge on the relative size of immigrant communities.     

Heaven's Swing Door: Endogenous Skills,Migration Networks,and the Effectiveness of Quality‐Selective Immigration Policies

A growing number of OECD countries are leaning toward the adoption of selective immigration policies, which are expected to raise the quality (or education level) of migrants. This view neglects two important dynamic effects: the role of migration networks, which could reduce the quality of migrants, and the responsiveness of education decisions to the prospect of migration. We propose a model of self‐selection into migration with endogenous education choices, which predicts that migration networks and the quality of migrants can be positively associated when destination countries adopt sufficiently selective immigration policies. Empirical evidence, presented as background motivation, suggests that this is indeed the case.     

The determinants of internal migration in a developing country: quantitative evidence for Indonesia, 1930–2000

This study specifies and estimates a gravity model for interprovincial migration in Indonesia. Analysing five cross-sections for Indonesia's 26 provinces for five survey years between 1930 and 2000 we show that throughout the twentieth century economic factors were more important in the explanation of interprovincial migration patterns in Indonesia than planned migration policy aimed at the redistribution of the population. In addition, our regression analysis demonstrates that the urban primacy of Jakarta, Indonesia's capital, had a strong effect on the direction and size of migration flows. Our findings thus suggest that the costly government-supported migration is not very successful and that a strongly centralized government induces migration flows to the capital. These findings have policy implications for other developing countries.     

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.     

Partisan politics: The empirical evidence from OECD panel studies

This paper describes the empirical evidence on partisan politics in OECD panel studies. I elaborate on the research designs, the measurement of government ideology and why the empirical studies did not derive causal effects. Discussing about 100 panel data studies, the results indicate that leftwing and rightwing governments pursued different economic policies until the 1990s: the size and scope of government was larger when leftwing governments were in power. Partisan politics have not disappeared since the 1990s, but have certainly become less pronounced. In particular, government ideology still seems to influence policies such as privatization and market deregulation. I discuss the consequences of declining electoral cohesion and what future research needs to explore.     

CONDITIONING AID ON SOCIAL EXPENDITURES

Aid conditionality forces countries to adopt policies that they would not otherwise choose. We examine how government discretion should be so constrained when the donor cannot fully control public expenditures, but instead can influence a less disaggregated indicator of public policy, namely the allocation of public spending between the social sectors (e.g. education, health, etc.) on the one hand and more traditional public goods (e.g. infrastructure) on the other. We first show how budget allocations will be altered when recipient government preferences are known – i.e. we characterize what policies the donor should "buy"– and how a given aid budget should be allocated between different types of countries. When recipient government preferences are not known by the donor, the permitted policies are distorted due to incentive constraints, and the extent to which aid flows are optimally differentiated between different countries is reduced.     

Income maximization and the selection and sorting of international migrants

Two prominent features of international labor movements are that the more educated are more likely to emigrate (positive selection) and more educated migrants are more likely to settle in destination countries with high rewards to skill (positive sorting). Using data on emigrant stocks by schooling level and source country in OECD destinations, we find that a simple model of income maximization can account for both phenomena. Results on selection show that migrants for a source-destination pair are more educated relative to non-migrants the larger is the absolute skill-related difference in earnings between the destination country and the source. Results on sorting indicate that the relative stock of more educated migrants in a destination is increasing in the absolute earnings difference between high and low-skilled workers. We use our framework to compare alternative specifications of international migration, estimate the magnitude of migration costs by source-destination pair, and assess the contribution of wage differences to how migrants sort themselves across destination countries.     

Migrant Networks: Empirical Implications for the Italian Bilateral Trade

A significant number of empirical studies, focusing on different countries, have found a positive link between migration and trade. This paper studies the relationship between emigration, immigration and trade using Italian data. The sample regards 51 foreign trading partners and spans from 1990 to 2005. The results suggest that networks of Italian emigrants in foreign countries boost bilateral trade. The effects of immigrants are weak on exports and negative on imports. Results do not change when cultural and institutional dissimilarities between countries are considered.     

The political economy of the impossible trinity

This paper reconsiders the policy trilemma in an open economy by incorporating political economy concerns. We argue that the impact of government ideology on monetary independence, exchange rate stability, and capital flow restrictions should be analyzed in the broader context of restrictions imposed by the impossible trinity instead of the usual single-dimensional constraints. Employing a de facto measurement of these restrictions for a sample of 111 countries from 1980 to 2010, we show that the impact of government ideology on a country's position in this trilemma is highly context dependent: we find that its impact on exchange rate stability and monetary independence varies between developed and developing countries. We also show that the impact of government ideology on these two trilemma components is contingent on the stance of the respective economy's business cycle. Left-leaning governments seem to favor exchange rate stability over monetary independence in case of a negative output gap; suggesting a reversal of their commonly assumed partisan preferences in economically tight times.     

Selective immigration policies, human capital accumulation and migration duration in infinite horizon

An increasing literature fosters selective immigration policies as a tool to increase human capital in both source and destination countries. These policies are supposed to prompt incentives to education, and–if selection is sufficiently severe–to increase the human capital stock in source countries. Nonetheless, when compared to open migration, selective policies make returns to education uncertain, and they may harm incentives to invest in human capital. As a consequence, they may reduce the human capital stock even though selection is “severe”. Moreover, when repeated migration is possible, they backfire on migration duration. We obtain our results in an infinite-horizon model that, unlike the current literature, places no restriction on the number of possible migration spells and allows for the possibility of a forced emigration.     

Rural-to-urban migration, human capital, and agglomeration

A new general-equilibrium model that links together rural-to-urban migration, the externality effect of the average level of human capital, and agglomeration economies shows that in developing countries, unrestricted rural-to-urban migration reduces the average income of both rural and urban dwellers in equilibrium. Various measures aimed at curtailing rural-to-urban migration by unskilled workers can lead to a Pareto improvement for both the urban and rural dwellers. In addition, the government can raise social welfare by reducing the migration of skilled workers to the city. Moreover, without a restriction on rural-to-urban migration, a government's efforts to increase educational expenditure and thereby the number of skilled workers may not increase wage rates in the rural or urban areas.     

2010年英国的科技政策和科技举措

纵观英国2010年的科技发展概况,财政紧缩成为英国科研投入的“紧箍咒”。尽管英国把科学研究经费保持在原来的464亿英镑水平,这意味着英国的核心科研经费在很大程度上得到了保证,但笔者认为从整体上对英国未来的创新不利。英国政府适时推出了一系列重要科技举措,其中包括稳定核心科研经费、设定技术移民限额、发布国家基础设施规划、支持企业行动和计划、筹备建立世界上第一个绿色投资银行等,举措影响深远。     

Fiscal policy in a small open economy with cross-border labor mobility

The large and stable inflow of workers’ remittances through formal financial channels to developing countries prompted authorities to harness fiscal resources from this flow. This paper develops a macro-dynamic model of a small open economy with cross-border labor mobility emphasizing fiscal policy. The flow of remittances is the result of a household’s optimizing decision to migrate. We examine the macroeconomic responses to fiscal policies. First, we show that an economy with international migration is more resilient to demand shocks resulting from fiscal contraction. Second, the short-run association between remittances and domestic output depends on the sources of the shocks. Third, our results indicate that the equilibrium impact of a tax on remittances can be expansionary and welfare-improving when an economy is initially close to full employment. The presence of utility-enhancing government expenditure and a potential negative externality from over-allocation of labor abroad (over migration) justify the presence of distortionary taxes.     

Reforms that keep you at home: The effects of economic transition on migration

Theory asserts that individuals’ migration decisions depend more on their expectations about future income levels than on their current income levels. We find that the implementation of market-oriented reforms in post-communist countries, by forming positive economic prospects, has reduced emigration as predicted by theory. Our estimates show that migration flows are highly responsive to reforms supporting private enterprises and financial services, which provide individuals with strong signals about their future prospects. We show that reforms that improve the management of infrastructure services have no link with migration patterns, which may be an important lesson for government policy.     

The influence of remittances on education and health outcomes: a cross country study

We study the effect of international remittances on aggregate educational and health outcomes using a sample of 69 low- and middle-income countries. We find that remittances play an important role in improving primary and secondary school attainment, increasing life expectancy and reducing infant mortality. Our results suggest that as migration laws continue to support greater emigration and remittances, policies should be enacted to facilitate the flow of remittances as they represent a significant source for economic development.     

Culture and Economic Performance: Policy as an Intervening Variable

The role of cultural factors in determining relative rates of economic growth is shown to involve the interrelationship between cultural factors and governmental ability to institute growth-oriented policies in addition to the direct effects of cultural values on recognized economic forces. The role of culture can exert, therefore, a substantial indirect component and that component depends directly upon the form of government and political conditions in the different countries.     

General or central government? Empirical evidence on political cycles in budget composition using new data for OECD countries

Previous studies used general government data to examine whether national governments’ electoral motives and ideology influenced budget composition in OECD countries. General government data includes, however, the state and local level. Using new data for general and central government over the period 1995–2016, I reexamine political cycles in budget composition. The results suggest that, both at the general and central government level, leftwing governments spent more on education and less on public services than rightwing governments. Defense expenditure was somewhat lower under leftwing than rightwing governments and in election years; especially in federal states. Effects of government ideology on the individual expenditure categories are larger at the central than general government level. Scholars need to re-examine results on ideology-induced effects that have been derived from general government data where central government data should have been used.     

Politics and privatization in Central and Eastern Europe

This article examines how government ideology influenced privatization efforts in Central and Eastern Europe after the transition from socialism. We analyse a dataset of privatization indicators covering small‐ and large‐scale industries in 19 transition countries over the period 1990–2007 and introduce a government ideology index. The results suggest that market‐oriented governments promoted the privatization of small‐scale industries more than that of large‐scale ones. In the rapid transition process in the early 1990s, leftist governments stuck to public ownership more strongly than in the following period from the mid‐1990s to 2007. The remarkable differences between leftist and right‐wing governments concerning both the role of government in the economy and the basic elements of political order are in line with developments in OECD countries, and may also hold further implications for transition and democratizing countries outside Central and Eastern Europe.     

Credit rationing and capital accumulation with investment and consumption loans revisited

A simple model is developed to evaluate the roles of credit rationing and government policies of financial repression in the process of capital accumulation. In the model, credit rationing on both investment and consumption loans decreases as capital accumulates but increases as the government imposes policies of financial repression to a greater extent. While a reduction in credit rationing on consumption loans impedes capital accumulation, such a reduction on investment loans facilitates it. We find that developing countries may be trapped at a low-capital-stock steady state while developed countries converge to a high-capital-stock steady state. Instead of adopting policies of financial liberalization, interestingly, this paper finds that policies of financial repression may enable developing countries to escape the development trap.
