The influence of rapid rural-urban migration on Korean national fertility levels

A autoregressive model is applied to personal migration and pregnancy histories recorded in the 1974 Korean World Fertility Survey to assess the adaptation effect of rural-urban migration on migrant fertility and national fertility levels. The objective of this study is to provide policy makers in developing nations with a model that will enable them to quantify the effects of rapid urbanization on the fertility level of migrant women and thus on national fertility levels. The fertility of rural-urban migrants is on the average lower than that of rural stayers; this study supports the adaptation hypothesis and indicates that rural-urban migrants experienced a significant reduction in 5 year fertility rates from those of comparable rural stayers after migration to the urban area. In addition, the city specific effects of migration on fertility are of considerable importance; migrants to larger cities adapt more over their lifetime than migrants to smaller cities. The completed adaptation by postmarital, rural-urban migrants is largest among migrants who are least educated. The autoregressive model controls the fertility level at the beginning of the observed period; it is assumed that this is a proxy for family size preferences. Results show that the completed fertility of migrant women with less than 4 years of school is 1.9 children fewer than that of comparable rural stayers, 1 child fewer for migrant women with 4 to 6 years of school, and .8 children fewer for migrant women with at least 6 years of school. For Korea, the overall effects on national fertility of rural-urban migration represent a reduction of 1.79 births per woman for the 1965-1970 period; it is estimated that the 945,400 rural-urban women migrants of this period would avoid, on average, 71,300 births annually for their expected average 24 years of urban life.     

International migration and trade agreements: The new role of PTAs

This paper provides an empirical analysis of the relationship between preferential trade agreements (PTAs) and bilateral migration flows. Building on the empirical literature on the determinants of migration flows, I estimate a modified gravity model to assess the role of PTAs and their content on bilateral migration flows. Using a sample of 29 OECD destination countries over the period 1998–2008, I show a strong positive effect of PTAs on bilateral migration flows. I find that the content of PTAs also matters: when visa‐and‐asylum and labour market related provisions are included in PTAs, this further stimulates bilateral migration flows. Different estimation strategies, including instrumental variables, are employed to address the potential endogeneity bias problems related to PTAs and their content.     

Population Ageing and House Prices in Australia

This article assesses the effect of population ageing on housing consumption and house prices. Using two approaches, this article finds that the ageing of the population may cause average real house prices to be between 3 and 27 per cent lower than they otherwise would be over the period 2008–2050. The first approach is an econometric estimation of house prices for Australia over the period 1980–2008. The second approach is a simulation of a life cycle‐optimising model with representative overlapping generations.     

Farm settlement with imperfect capital markets: a life-cycle application to Upper Canada, 1826–1851

Farm settlement, where borrowing is constrained, is addressed with a life‐cycle model. Because a pioneer farm must be cleared before becoming productive, the settler first accumulates in order to purchase supplies and maintain consumption during the initial years. Implications of the model are explored using data from Upper Canada, 1826–1851: age at settlement is delayed. Settlers eventually receive higher incomes than those who do not settle; rising life expectancy contributes to settlement; an immediate income is a prerequisite to settlement. Such findings conform to the experience of Upper Canada and other pioneer areas and may also illuminate aspects of migration. JEL classification: N31, J61 Colonisation agricole quand les marchés du capital sont imparfaits:une application du modèle du cycle de vie au Haut‐Canada, 1826–51. L'auteur examine le processus de colonisation agricole quand il y a contraintes sur les emprunts à l'aide d'un modèle de cycle de vie. Parce qu'un pionnier doit d'abord défricher avant que la ferme ne soit productive, le colon doit avoir préalablement accumulé un certain pécule afin de pouvoir acheter le matériel nécessaire et maintenir sa consommation durant les premières années de colonisation. On analyse les implications de ce modèle en utilisant les données pour le Haut Canada de 1826 à1851. Entre autres résultats, on note que l'âge où l'on s'installe est reporté; que ceux qui colonisent éventuellement reçoivent des revenus beaucoup plus élevés que ceux qui ne le font pas; que la croissance de l'espérance de vie tend à encourager la colonisation; et qu'une source immédiate de revenus est un prérequis à la colonisation. Ces résultats et certains autres sont conformes à ce que l'on observe dans le Haut Canada et dans les autres zones de colonisation, et il peuvent jeter un peu de lumière sur certains aspects du processus de migration.     

THE EFFECT OF HUSBAND'S JOB DISPLACEMENT ON THE TIMING AND SPACING OF BIRTHS IN THE UNITED STATES

I use husband's job displacement as an exogenous shock to identify the effect of income on the timing and spacing of births. Gradual adjustment of fertility to income shock is considered in life‐cycle model with uncertainty. Flexible hazard model, estimated jointly for the first three births, allows household's fertility to be affected not only in the period of displacement but also before and after. General displacements and layoffs have negative log‐run effect on the timing and spacing of only the first and the third births. The effect persists with nonparametric controls for woman‐ and transition‐specific heterogeneity, and after robustness checks. (JEL J13, J63, C41)     

Investment opportunities in the source country and temporary migration

Abstract This paper examines how attractive investment opportunities available to temporary migrants at home affect their saving behaviour and the optimal duration of stay abroad. The model predicts an inverse U‐shaped relationship between migration duration and the expected rate of return on repatriated savings. A higher rate provides an incentive to go back earlier and consume less abroad, while it can also trigger emigration aimed at generating the savings required for investment after return. The paper illustrates how the behaviour of temporary migrants reflects the interaction between their preferences and the opportunities available in labour and capital markets of both countries.     

Investing back homeReturn migration and business ownership in Albania1

This study uses data from the 2005 Albania Living Standards Measurement Study survey to assess the impact of past migration experience of Albanian households on non‐farm business ownership through instrumental variables regression techniques. Considering the differences in earning potentials and opportunities for skill acquisition in different destination countries, we differentiate the impact of past household migration experience by main migrant destinations. The study also explores the heterogeneity of impact based on the timing of migration. The empirical results indicate that past household migration experience exerts a positive impact on the probability of owning a non‐farm business. While one additional year in Greece increases the probability of household business ownership by roughly 6 percent, a similar experience in Italy or farther destinations raises the probability by over 25 percent. Although past household migration experience for the period of 1990–2000 is positively associated with the likelihood of owning a household enterprise, a similar association does not exist for the period of 2001–2004.     

Capital accumulation through studying abroad and return migration

This paper examines the interplays among studying abroad, return migration and capital accumulation, in a dynamic general equilibrium model featuring heterogeneous ability. Households invest in education and make two migration decisions: whether to study abroad and subsequently whether to return home. The model predicts that the highest, middle and lowest-ability people choose respectively permanent migration, return migration and no migration. More interestingly, we find a novel migration cycle: returnees bring back learned-knowledge and over time, capital accumulates, attracting more return migration. Further, the usual “brain drain” in the literature can be turned into “brain gain”, by providing a subsidy to studying abroad and returning home.     

Subjective mortality expectations and consumption and saving behaviours among the elderly

Abstract Life expectancy is an important factor that individuals have to take into account for saving and consumption choices. The life‐cycle model of consumption and saving behaviour predicts that consumption growth should decrease with higher mortality rates. The aim of this study is to test this hypothesis based on data about subjective longevity expectations from the Health and Retirement Study merged with detailed consumption data from two waves of the Consumption and Activities Mail Survey. This study finds that an increase in subjective mortality by 1% corresponds to an annual decrease in consumption of non‐durable goods of around 1.8%.     

Optimal Taxation of Risky Human Capital*

In a two‐period life‐cycle model with ex ante homogeneous households, earnings risk, and a general earnings function, we derive the optimal linear labor tax rate and optimal linear education subsidies. The optimal income tax trades off social insurance against incentives to work. Education subsidies are not used for social insurance, but they are only targeted at offsetting the distortions of the labor tax and internalizing a fiscal externality. Both optimal education subsidies and tax rates increase if labor and education are more complementary, because education subsidies indirectly lower labor tax distortions by stimulating labor supply. Optimal education subsidies (taxes) also correct non‐tax distortions arising from missing insurance markets. Education subsidies internalize a positive (negative) fiscal externality if there is underinvestment (overinvestment) in education because of risk. Education policy unambiguously allows for more social insurance if education is a risky activity. However, if education hedges against labor‐market risk, optimal tax rates could be lower than in the case without education subsidies.     

Optimal Age-Specific Income Taxation

This paper studies optimal earnings taxation in a three‐period life‐cycle model where taxes can be differentiated according to age. Agents choose their level of education when young and their retirement age when old. I study the problem both without and with borrowing constraints. It is shown that, without borrowing constraints, a first‐best optimum can be decentralized by setting a zero tax rate in the third period and a first‐period tax lower than the second‐period one. With borrowing constraints, the first best can no longer be achieved. The gap between the first‐ and second‐period tax rates is larger, while the third‐period tax rate is generally different from zero.     

Remittances and return migration

This paper utilizes survey data of return migrants to analyze the determinants of remittances sent while the migrants were abroad. We approach our research question from the perspective of three sending countries in the Maghreb, namely Algeria, Morocco, and Tunisia. We investigate the remittance behavior using the migrants’ conditions before migration as well as during the migration experience. Using a two‐part model, we show that the decision to remit and the amount remitted depend on a combination of different migrant characteristics and reasons for migration as well as the form of migration. More importantly, we also consider if the remittance behavior is dependent on the type of return: “decided” or “compelled.” We show that the two groups have different incentives to remit, which can help explain the link between type of migrants and their remittance behavior.     

International migration,foreign direct investment,and development stage in developing economies

The existing empirical results on the relationship between FDI and migration are rather mixed. This study reevaluates, both theoretically and empirically, how inward FDI relates to emigration in developing countries. Our model illustrates that the relationship between inward FDI and emigration flows depends on the development stage of a developing country, that is, there is a positive association between inward FDI and emigration flows for relatively less‐developed countries but a negative association between these two variables for relatively developed countries. We confirm the empirical validity of our model prediction using the panel data of 21 OECD and 51 non‐OECD countries during the period from 2003 to 2012. Our results argue that as economic development proceeds in a developing country, the home effect of inward FDI associated with intensified labor demand would dominate the linkage effect that induces the brain drain problem through enhancing the socioeconomic ties with migrant networks.     

Life‐Cycle Patterns of Interest‐Rate Mark‐Ups in Small‐Firm Finance*

We derive empirical implications from a theoretical model of bank–borrower relationships. The interest‐rate mark‐ups of banks are predicted to follow a life‐cycle pattern over the age of the borrowing firms. Because of endogenous bank monitoring by competing banks, borrowing firms initially face a low mark‐up, and thereafter an increasing mark‐up as a result of informational lock‐in, until it falls for older firms when the lock‐in is resolved. By applying a large sample of predominantly small unlisted firms and a new measure of asymmetric information, we find that firms with significant asymmetric‐information problems have a more pronounced life‐cycle pattern of interest‐rate mark‐ups. Additionally, we examine the effects of concentrated banking markets on interest‐rate mark‐ups. The results indicate that the life cycle of mark‐ups is mainly driven by asymmetric‐information problems and not by concentration. However, we find evidence that bank market concentration matters for older firms ? 2 Correction added after online publication on 20^th February 2012; the original text read ‘However, we find evidence that bank market concentration for older firms’, omitting the word ‘matters’.
     

HAS INTERNATIONAL CAPITAL MOBILITY INCREASED IN ASIA? EVIDENCE FROM THE POST‐1997 FINANCIAL CRISIS PERIOD

This paper examines whether international capital mobility in Asia has increased after the 1997 Asian financial crisis by estimating the Feldstein‐Horioka (FH) coefficients using panel cointegration and dynamic OLS regressions. In the benchmark estimation, we find that the FH coefficients of ten Asian economies decrease significantly from 0.65 during the pre‐crisis period to 0.32 during the post‐crisis period. Furthermore, the coefficient for the post‐crisis period is less statistically significant than that for the pre‐crisis period. The extended model estimations with additional control variables controlling for the business cycle, different foreign exchange rate systems, and capital control also show the results which are consistent with the benchmark estimation results. Rolling regressions show a consistently declining trend of the FH coefficients in Asia during our sample period. These results provide consistent evidence, according to the FH proposition, of increasing international capital mobility in Asia during the post‐1997 Asian financial crisis period.

HOUSING WEALTH AND U.S. MONEY DEMAND: A PANEL ESTIMATION

This article estimates a panel model for U.S. money demand using annual state‐level data for the period from 1977 to 2008. We incorporate housing wealth in the demand‐for‐money function and find strong evidence of a relationship between a broad monetary aggregate and housing wealth. This finding is robust to the inclusion of variables measuring financial heterogeneity across U.S. regions. Breaking up the sample in two subperiods shows that panel estimates including housing wealth yield more stable coefficients than both time‐series estimates and panel estimates excluding housing wealth. We also show that the link between money and housing wealth predates the recent boom‐and‐bust cycle. (JEL E41, E52)     

On the Cost of Opportunistic Behavior in the Public Sector: A General‐Equilibrium Approach

This paper studies the wasteful effect of bureaucracy on the economy by addressing the link between opportunistic behavior of government bureaucrats and the public sector wage bill. In particular, public officials are modeled as individuals competing for a larger share of those public funds. A simple extraction technology in the government administration is introduced in a standard real‐business‐cycle setup augmented with detailed public sector. The model is calibrated to German data for the period 1970–2007. The main findings are: (i) the model performs well vis‐à‐vis the data; (ii) due to the existence of a significant public sector wage premium and the high public sector employment, a substantial amount of working time is spent in opportunistic activities, which, in turn, leads to significant losses in terms of output; and (iii) the model‐based loss measures obtained for the EU‐12 countries are highly correlated to indices of bureaucratic inefficiency.     

Economic and Social Motivation‐Based Im/migration Modeling: The Case of Turkey

This paper aims to develop a generally applicable model to examine the eventual motivations both for internal migration and external immigration. For this reason our model involves not only economic motivations of development and geographical economics but also social motivations of behavior economics. We tested the model through Turkish internal and external population flows toward German regions. Our analysis contains the first regional‐level immigration analysis between an EU country (Germany) and Turkey. The main results are: (i) the purely economic motivations are more important than the social motivations; (ii) among the economic motivations income level and economic size of host regions are the biggest ones; and (iii) and the network externalities play a more important role than the herd effect. Subsequently, we estimated some country‐specific factors on im/migration. The main results are: (i) joining to the Customs Union led to acceleration in intern migration but slowing‐down in external immigration; (ii) even though Turkey acts slowly in adopting EU reforms, the EU reform process seems to reduce the economic and social stress on Turkish im/migration; and (iii) the reunification of Germany created a constraint on Turkish immigration flows toward German regions.     

Return migration, wage differentials, and the optimal migration duration

In simple static models, migration increases with the wage differential between host- and home-country. In a dynamic framework, and if migrations are temporary, the size of the migrant population in the host country depends also on the migration duration. This paper analyses optimal migration durations in a model which rationalises the decision of the migrant to return to his home country, despite persistently higher wages in the host country. The analysis shows that, if migrations are temporary, the optimal migration duration may decrease if the wage differential grows larger. Using micro data for Germany, the second part of the paper provides empirical evidence which is compatible with this hypothesis.
