Diaspora effects in international migration : key questions and methodological issues

2011-06-30T04:00:00.000Z

This paper reviews the existing literature on the impact of migrants networks on the patterns of international migration. It covers the theoretical channels at stake in the global effect of the networks. It identifies the key issues, namely the impact on size, selection and concentration of the migration flows. The paper also reviews the empirical hurdles that the researchers face in assessing the importance of networks. The key issues concern the choice of micro vs a macro approach, the definition of a network, the access to suitable data and the adoption of econometric methods accounting for the main features of those data. Finally, the paper reports a set of estimation outcomes reflecting the main findings of the macro approach.

Mixtures of g-priors for Bayesian Model Averaging with economic application

2011-07-25T04:00:00.000Z

This paper examines the issue of variable selection in linear regression modeling, where there is a potentially large amount of possible covariates and economic theory offers insufficient guidance on how to select the appropriate subset. In this context, Bayesian Model Averaging presents a formal Bayesian solution to dealing with model uncertainty. The main interest here is the effect of the prior on the results, such as posterior inclusion probabilities of regressors and predictive performance. The authors combine a Binomial-Beta prior on model size with a g-prior on the coefficients of each model. In addition, they assign a hyperprior to g, as the choice of g has been found to have a large impact on the results. For the prior on g, they examine the Zellner-Siow prior and a class of Beta shrinkage priors, which covers most choices in the recent literature. The authors propose a benchmark Beta prior, inspired by earlier findings with fixed g, and show it leads to consistent model selection. Inference is conducted through a Markov chain Monte Carlo sampler over model space and g. The authors examine the performance of the various priors in the context of simulated and real data. For the latter, they consider two important applications in economics, namely cross-country growth regression and returns to schooling. Recommendations for applied users are provided.

Lasting welfare effects of widowhood in a poor country

2011-07-26T04:00:00.000Z

Little is known about the situation facing widows and their dependent children in West Africa especially after the widow remarries. Women in Malian society are vulnerable to the loss of husbands especially in rural areas. Households headed by widows have significantly lower living standards on average than male or other female headed households in both rural and urban areas; this holds both unconditionally and conditional on observable household and individual characteristics including age. Furthermore, the adverse welfare effects of widowhood appear to persist even after widows are absorbed into male headed households. An examination of individual measures of well-being further reveals that, relative to other women, worse outcomes for ever-widowed women persist through remarriage. These detrimental effects are passed on to children, indicating an intergenerational transmission of poverty stemming from widowhood.

Tastes, castes, and culture : the influence of society on preferences

2011-08-15T04:00:00.000Z

Economists have traditionally treated preferences as exogenously given. Preferences are assumed to be influenced by neither beliefs nor the constraints people face. As a consequence, changes in behaviour are explained exclusively in terms of changes in the set of feasible alternatives. Here the authors argue that the opposition to explaining behavioural changes in terms of preference changes is ill-founded, that the psychological properties of preferences render them susceptible to direct social influences, and that the impact of "society" on preferences is likely to have important economic and social consequences.

Women's decision making power and human development : evidence from Pakistan

2011-10-05T04:00:00.000Z

When deciding who should receive welfare benefits with the aim to increase household well-being, it is necessary to understand the effects of the distribution of power within the households at which the aid is directed. Two primary household models have been used to study intra-household bargaining and decision making: the unitary model and the collective model. The unitary model seems to fit Pakistan's context because the prevailing traditional culture positions the male head as the household decision maker. However, using a set of direct measures of decision-making power from the Pakistan Social and Living Standard Measurement Survey, this study finds that even in a country where men seem to have more power than women, the collective household bargaining model applies. This study also finds that, in Pakistan, when women have more decision-making power at home, households tend to spend more on women's preferred goods (such as clothing and education), family members eat more non-grain food items, and children, particularly girls, are more likely to be enrolled in school.

Life satisfaction, social capital and the bonding-bridging nexus

2012-01-12T05:00:00.000Z

The paper investigates the relation between social capital and life satisfaction focusing on the distinction between bonding and bridging. Using the latest version of the combined World and European Values Surveys, the authors first address the question of measurement of social capital by means of a multi-step factor analysis. Through this procedure, they nd that proxies typically used for social capital tend to polarize around two dimensions interpreted as bonding and bridging. These two dimensions are in fact associated with a single latent variable with opposite signs suggesting that they describe two sides of the same latent variable rather than two independent latent variables. The authors call this latent variable the locus of socializing and use it to explore the relation between social capital and life satisfaction across world citizens and across groups of similar countries. The results indicate that people with extreme bonding or bridging attitudes are less happy than people with more balanced attitudes. Unlike the literature on social capital and economic growth that finds bridging attitudes more desirable than bonding attitudes, they nd that bonding attitudes are at least as important as bridging attitudes for life satisfaction. This suggests that the social capital dimensions important for economic growth may not necessarily coincide with the social capital dimensions important for life satisfaction.

The contribution of African women to economic growth and development : historical perspectives and policy implications -- Part I : the pre-colonial and colonial periods

2012-04-25T04:00:00.000Z

Bringing together history and economics, this paper presents a historical and processual understanding of women's economic marginalization in Sub-Saharan Africa from the pre-colonial period to the end of colonial rule. It is not that women have not been economically active or productive; it is rather that they have often not been able to claim the proceeds of their labor or have it formally accounted for. The paper focuses on the pre-colonial and colonial periods and outlines three major arguments. First, it discusses the historical processes through which the labor of women was increasingly appropriated even in kinship structures in pre-colonial Africa, utilizing the concepts of "rights in persons" and "wealth in people." Reviewing the processes of production and reproduction, it explains why most slaves in pre-colonial Africa were women and discusses how slavery and slave trade intensified the exploitation of women. Second, it analyzes how the cultivation of cash crops and European missionary constructions of the individual, marriage, and family from the early decades of the 19th century sequestered female labor and made it invisible in the realm of domestic production. Third, it discusses how colonial policies from the late 19th century reinforced the "capture" of female labor and the codification of patriarchy through the nature and operation of the colonial economy and the instrumentality of customary law. The sequel to this paper focuses on the post-colonial period. It examines the continuing relevance and impact of the historical processes this paper discusses on post-colonial economies, and suggests some policy implications.

Experiments in culture and corruption : a review

2012-05-08T04:00:00.000Z

Two decades of empirical evaluation have shown that corruption has a negative impact on economic growth, political stability, judicial effectiveness, democratization, educational attainment, and equality of income. However, corruption exists, persists, and varies significantly by culture. Lab studies have recently come to the forefront in identifying both the incentives and disincentives for corrupt behavior. However, lab studies on culture and corruption have led to some puzzling, contradictory results. This paper begins with a discussion of non-experimental work in this area, and evaluates the experimental findings in the context of earlier research. The authors sketch out the channels through which culture interacts with corruption (through institutions and social norms), and argue that discrepancies in experimental results may be due to differences in design (including repetition or unobserved variation in beliefs) or to differences in the response to punishment across societies. In addition to exploring design-based reasons for previous contradictory findings, avenues for future research include: behavioral responses to different types of externalities; replicating results in different countries; and utilizing the lab to formulate effective anti-corruption measures.

Internal migration in Egypt : levels, determinants, wages, and likelihood of employment

2012-08-13T04:00:00.000Z

This paper describes stylized facts about internal migration and the labor force in Egypt, and shows how internal migration in the country is low compared with international standards. Using aggregate labor force survey data, the paper shows how individuals migrate to governorates with higher wages. With a Mincerian equation, the analysis finds that migrants earn premiums with respect to non-migrants, except for those migrants with low education levels. The aggregate labor statistics reveal lower unemployment rates among migrants, a phenomenon that is verified by an employment equation. According to the econometric results, migrants are more likely to be employed, even after controlling for other observable individual characteristics. Finally, the paper estimates a Probit model for the decision to migrate, finding that more educated individuals are more likely to migrate, agricultural workers have a lower probability of migrating, and individuals from governorates in which food production for own consumption is higher are less likely to migrate. These results suggest that low educational attainment and the "food problem", which ties resources to food production to meet subsistence requirements, are at the root of low migration in Egypt.

Tourism sector in Panama : regional economic impacts and the potential to benefit the poor

2012-08-29T04:00:00.000Z

Tourism is one of Latin America's fastest growing industries but the impact of tourism on the poor and the effects on lagging regions are under debate. Many studies have evaluated the growth impacts of the tourism sector but few have analyzed the impact of tourism on the economy and poverty at the subnational level in developing countries. As a country marked by a "dual economy," Panama shares with other Latin American countries a fast growing, modern urban sector side by side with impoverished rural and peri-urban populations. Tourism has been growing in Panama and contributes at least 6 percent of gross domestic product. This paper presents the results of a top-down assessment of the impact of tourism spending on growth and poverty at the regional (province) level in Panama using a Social Accounting Matrix model. As revealed by this study, the tourism sector has large multiplier effects on the Panamanian economy and has the potential for significant benefits to the poor. But tourism's poverty benefits are neither automatic nor ubiquitous. They depend on where and how supply chains are structured and on the way tourists spend their money.

Migration and the transition to adulthood in contemporary Malawi

2012-09-17T04:00:00.000Z

In many African countries, the timing of important life events -- such as school-leaving, first marriage, and entry into the labor market -- is thought to be strongly tied to migration. This paper investigates the relationship between major life events, household characteristics, and migration among adolescents and young adults in contemporary Malawi. The specific research questions are twofold. First, what are the socio-economic and demographic determinants of migration? Second, how do school attendance, first marriage, and employment-seeking relate to migration patterns? The study uses panel data collected from a survey designed specifically to explore socioeconomic and demographic aspects of youth transitions to adulthood and which tracked respondents as they moved to new dwellings. Among the sample, they find that moves are not uncommon, and the predominant reasons for moves are non-economic. Although historically ethnic traditions in this area have held that girls and women usually did not move upon marrying, the data show that women were more likely to move between survey rounds than boys and men, and that marriage was the main reason for doing so. Closer ties to the head of the household are associated with less movement for both women and men.

Making up people -- the effect of identity on preferences and performance in a modernizing society

2012-10-10T04:00:00.000Z

It is typically assumed that being hard-working or clever is a trait of the person, in the sense that it is always there, in a fixed manner. However, in an experiment with almost 600 boys in India, cues to one's place in the traditional caste order turn out to influence the expression of these traits. The experiment assigned students to different treatments with respect to the salience of caste and had them solve mazes under incentives. It turned out that making caste salient can reduce output by about 25 percent, which is equivalent to twice the effect on output of being one year younger. The channels through which this occurs differ by caste status. For the upper castes, the decline in performance under piece rates can only be explained by a shift in preferences regarding the provision of effort. When the ascriptive caste order is cued, upper-caste individuals may think, "I don't need to excel." In contrast, for the lower castes, which were traditionally "untouchables," publicly revealing caste identity impairs the ability to learn and may lead individuals to think, "I can't (or don't dare to) excel." This paper provides a measure of the impact that ascriptive, hierarchized identities can have on preferences and performance after a society -- in its public pronouncements and legislation -- has adopted norms of equality in a formal sense. The findings are important because they suggest that when contexts cue identities founded on the superseded rules of a hierarchical institution, the effects on human capital formation and development can be first-order. Contexts that make traditional identities salient are an underemphasized source of impediments to institutional change.

Empowering women : evidence from a field experiment in Afghanistan

2012-11-19T05:00:00.000Z

In societies with widespread gender discrimination, development programs that encourage female participation in local governance can potentially redress gender imbalances in economic, political, and social outcomes. Using a randomized field experiment encompassing 500 Afghan villages, this study finds that a development program which incorporates mandated female participation increases female mobility and involvement in income generation, but does not change female roles in family decision-making or attitudes toward the general role of women in society.

Intrahousehold bargaining and resource allocation in developing countries

2013-01-23T05:00:00.000Z

Many key development outcomes depend on women's ability to negotiate favorable intrahousehold allocations of resources. Yet it has been difficult to clearly identify which policies can increase women's bargaining power and result in better outcomes. This paper reviews both the analytical frameworks and the empirical evidence on the importance of women's bargaining power. It argues that there is sufficient evidence from rigorous studies to conclude that women's bargaining power does affect outcomes. But in many specific instances, the quantitative evidence cannot rigorously identify causality. In these cases, a combination of quantitative and qualitative evidence may suggest policy levers. Taken together, there are sufficient data in place to support a greatly expanded focus on intrahousehold outcomes and bargaining power. Additional data at the individual level will allow for further and more detailed research. A growing literature supports the current conventional wisdom -- namely, that the patterns of evidence suggest that women's education, incomes, and assets all are important aspects of women's bargaining power.

Mass media and public policy : global evidence from agricultural policies

2013-02-14T05:00:00.000Z

Mass media play a crucial role in information distribution and in the political market and public policy making. Theory predicts that information provided by the mass media reflects the media's incentives to provide news to different groups in society and affects these groups' influence in policy making. The paper use data on agricultural policy from 69 countries spanning a wide range of development stages and media markets to test these predictions. The empirical results are consistent with theoretical hypotheses that public support for agriculture is affected by the mass media. In particular, an increase in media (television) diffusion is associated with policies that benefit the majority to a greater extent and is correlated with a reduction in agriculture taxation in poor countries and a reduction in the subsidization of agriculture in rich countries, ceteris paribus. The empirical results are consistent with the hypothesis that increased competition in commercial media reduces transfers to special interest groups and contributes to more efficient public policies.

Gender and agriculture : inefficiencies, segregation, and low productivity traps

2013-02-21T05:00:00.000Z

Women make essential contributions to agriculture in developing countries, where they constitute approximately 43 percent of the agricultural labor force. However, female farmers typically have lower output per unit of land and are much less likely to be active in commercial farming than their male counterparts. These gender differences in land productivity and participation between male and female farmers are due to gender differences in access to inputs, resources, and services. In this paper, the authors review the evidence on productivity differences and access to resources. They discuss some of the reasons for these differences, such as differences in property rights, education, control over resources (e.g., land), access to inputs and services (e.g., fertilizer, extension, and credit), and social norms. Although women are less active in commercial farming and are largely excluded from contract farming, they often provide the bulk of wage labor in the nontraditional export sector. In general, gender gaps do not appear to fall systematically with growth, and they appear to rise with GDP per capita and with greater access to resources and inputs. Active policies that support women's access and participation, not just greater overall access, are essential if these gaps are to be closed. The gains in terms of greater productivity of land and overall production are likely to be large.

Measuring the effect of a community-level program on women's empowerment outcomes : evidence from India

2013-04-04T04:00:00.000Z

This paper uses primary data from rural north India to show that participation in a community-level female empowerment program significantly increases access to employment, physical mobility, and political participation. The program provides support groups, literacy camps, adult education classes, and vocational training for rural women in several states of India; the data are from Uttarakhand. The paper uses instrumental variables and truncation-corrected matching on primary data to disentangle the program's mechanisms, separately considering its effect on women who work, and those who do not work but whose reservation wage is increased by participation. The analysis also finds significant spillover effects on non-participants relative to women in untreated districts. It finds consistent estimates for average treatment and intent to treat effects

Foreign job opportunities and internal migration in Vietnam

2013-04-24T04:00:00.000Z

This paper investigates the role of employment opportunities created by foreign-owned firms as a determinant of internal migration and destination choice using the Vietnam Migration Survey 2004 and the Vietnam Household Living Standards Survey 2004. Multinomial logit and conditional logit models are estimated to study both origin and destination-specific characteristics of migrants. The paper finds that the migration response to foreign job opportunities is larger for female workers than male workers; there appears to be intermediate selection in terms of educational attainment; and migrating individuals on average tend to go to destinations with higher foreign employment opportunities, even controlling for income differentials, land differentials, and distances between sending and receiving areas.

Eliciting illegal migration rates through list randomization

2013-04-29T04:00:00.000Z

Most migration surveys do not ask about the legal status of migrants due to concerns about the sensitivity of this question. List randomization is a technique that has been used in a number of other social science applications to elicit sensitive information. This paper trials this technique by adding it to surveys conducted in Ethiopia, Mexico, Morocco, and the Philippines. It shows how, in principal, this can be used both to give an estimate of the overall rate of illegal migration in the population being surveyed, as well as to determine illegal migration rates for subgroups such as more or less educated households. The results suggest that there is some useful information in this method: higher rates of illegal migration in countries where illegal migration is thought to be more prevalent and households who say they have a migrant are more likely to report having an illegal migrant. Nevertheless, some of the other findings also suggest some possible inconsistencies or noise in the conclusions obtained using this method. The authors suggest directions for future attempts to implement this approach in migration surveys.

Risk sharing and internal migration

2013-04-30T04:00:00.000Z

Over the past two decades, more than half the population in rural Tanzania migrated within the country, profoundly changing the nature of traditional institutions such as informal risk sharing. Mass internal migration has created geographically disperse networks, on which the authors collected detailed panel data. By quantifying how shocks and consumption co-vary across linked households, they show how migrants unilaterally insure their extended family members at home. This finding contradicts risk-sharing models based on reciprocity, but is consistent with assistance driven by social norms. Migrants sacrifice 3 to 7 percent of their very substantial consumption growth to provide this insurance, which seems too trivial to have any stifling effect on their growth through migration.
