Fifteen years of inequality in Latin America : how have labor markets helped ?

2013-03-13T04:00:00.000Z

Household income inequality has declined in Latin America in the past decades, contributing significantly to poverty reduction in the region. Although available evidence shows that changes in the labor income are among the main factors behind these inequality trends, few studies have analyzed more closely the labor market dynamics that have led to a decline in total income inequality in some countries, but also to an increase in others. Using household survey data for a sample of 15 countries in Latin America from 1995 to 2010, this paper uses an extension of the Juhn-Murphy-Pierce methodology to decompose changes in labor income inequality (hourly wages) into a quantity effect (capturing changes in the distribution of workers' skills), price effect (reflecting returns to skills), and unobservables effect (other components, within skill groups, affecting labor income). The results show that falling returns to skills for both education and experience is, on average, driving the decline in labor income inequality in Latin America. The quantity effect, in turn, has contributed little to inequality reduction, mostly attributable to a larger dispersion in years of experience, possibly linked to the region's demographic transition and to significant increases in female labor force participation. Additional findings show that wage inequality, still high in the region, is coupled with inequality in terms of hours worked. The paper complements the existing literature by presenting separate results for males and females, as well as formal and informal sector workers as an attempt to control for secular shifts in these characteristics.

Food price volatility and domestic stabilization policies in developing countries

2013-03-27T04:00:00.000Z

When food prices spike in countries with large numbers of poor people, public intervention is essential to alleviate hunger and malnutrition. For governments, this is also a case of political survival. Government actions often take the form of direct interventions in the market to stabilize food prices, which goes against most international advice to rely on safety nets and world trade. Despite the limitations of food price stabilization policies, they are widespread in developing countries. This paper attempts to untangle the elements of this policy conundrum. Price stabilization policies arise as a result of international and domestic coordination problems. At the individual country level, it is in the national interest of many countries to adjust trade policies to take ad-vantage of the world market in order to achieve domestic price stability. When countercyclical trade policies become widespread, the result is a thinner and less reliable world market, which further decreases the appeal of laissez-faire. A similar vicious circle operates in the domestic market: without effective policies to protect the poor, such as safety nets, food market liberalization lacks credibility and makes private actors reluctant to intervene, which in turn forces government to step in. The current policy challenge lies in designing policies that will build trust in world markets and increase trust between pub-lic and private agents.

Gender equality and economic growth in Brazil : a long-run analysis

2013-03-28T04:00:00.000Z

This paper studies the long-run impact of policies aimed at fostering gender equality on economic growth in Brazil. The first part provides a brief review of gender issues in the country. The second part presents a gender-based, three-period OLG model that accounts for women's time allocation between market work, child rearing, human capital accumulation, and home production. Bargaining between spouses depends on relative human capital stocks, and thus indirectly on access to infrastructure. The model is calibrated and various experiments are conducted, including investment in infrastructure, conditional cash transfers, a reduction in gender bias in the market place, and a composite pro-growth, pro-gender reform program. The analysis showed that fostering gender equality, which may partly depend on the externalities that infrastructure creates in terms of women's time allocation and bargaining power, may have a substantial impact on long-run growth in Brazil.

Diasporas and outsourcing : evidence from oDesk and India

2013-04-08T04:00:00.000Z

This paper examines the role of the Indian diaspora in the outsourcing of work to India. The data are taken from oDesk, the world's largest online platform for outsourced contracts. Despite oDesk minimizing many of the frictions that diaspora connections have traditionally overcome, diaspora connections still matter on oDesk, with ethnic Indians substantially more likely to choose a worker in India. This higher placement is the result of a greater likelihood of choosing India for the initial contract, due in large part to taste-based preferences, and substantial path dependence in location choices. The paper further examines wage and performance outcomes of outsourcing as a function of ethnic connections.

Entrepreneurship programs in developing countries : a meta regression analysis

2013-04-08T04:00:00.000Z

This paper provides a synthetic and systematic review on the effectiveness of various entrepreneurship programs in developing countries. It adopts a meta-regression analysis using 37 impact evaluation studies that were in the public domain by March 2012, and draws out several lessons on the design of the programs. The paper observes wide variation in program effectiveness across different interventions depending on outcomes, types of beneficiaries, and country context. Overall, entrepreneurship programs have a positive and large impact for youth and on business knowledge and practice, but no immediate translation into business set-up and expansion or increased income. At a disaggregate level by outcome groups, providing a package of training and financing is more effective for labor activities. In addition, financing support appears more effective for women and business training for existing entrepreneurs than other interventions to improve business performance.

Joining, upgrading and being competitive in global value chains : a strategic framework

2013-04-09T04:00:00.000Z

In recent years, global value chains have played an increasing role in business strategies, profoundly affecting international trade and development paradigms. Global value chains now represent a major source of socio-upgrading opportunities and a new path for development. Trade, competitiveness and development policies should be reshaped accordingly to seize these opportunities and avoid the risks associated with greater participation in global value chains. This paper provides a framework and analytical tools for measuring and improving a country's performance with respect to participation in global value chains. With a clear operational focus, it provides guidance for countries willing to join, maintain participation, and/or move up global value chains. With the ultimate objective to increase the value (the development content) for trade, it also offers strategies to maximize the benefits and minimize the risks of developing countries' participation in global value chains.

Public policy and industrial transformation in the process of development

2013-04-09T04:00:00.000Z

This paper studies the role of public policy in promoting industrial transformation from an imitationbased, low-skill economy to an innovation-based, high-skill economy, where technological progress now occurs through the domestic invention of ideas. Industrial transformation is measured by changes in an index of industrial structure, defined as the ratio of the variety of imitation- to innovation-based intermediate goods. A key mechanism through which productivity increases initially in both the imitation and innovation sectors is through a knowledge externality associated with learning by doing in the imitation sector. The process of industrialization increases the demand for high-skill labor, inducing individuals to invest in education. The model also emphasizes the distinction between basic or core infrastructure, which promotes imitation, and advanced infrastructure, which promotes innovation. A calibrated version for a low-income country is used to perform several policy experiments, including an increase in investment in infrastructure, a reduction in the cost of training, and improved enforcement of property rights.

Food prices, wages, and welfare in rural India

2013-04-17T04:00:00.000Z

This paper considers the welfare and distributional consequences of higher relative food prices in rural India through the lens of a specific-factors, general equilibrium, trade model applied at the district level. The evidence shows that nominal wages for manual labor both within and outside agriculture respond elastically to increases in producer prices; that is, wages rose faster in rural districts growing more of those crops with large price run-ups over 2004-09. Accounting for such wage gains, the analysis finds that rural households across the income spectrum benefit from higher agricultural commodity prices. Indeed, rural wage adjustment appears to play a much greater role in protecting the welfare of the poor than the Public Distribution System, India's giant food-rationing scheme. Moreover, policies, like agricultural export bans, which insulate producers (as well as consumers) from international price increases, are particularly harmful to the poor of rural India. Conventional welfare analyses that assume fixed wages and focus on households' net sales position lead to radically different conclusions.

Export liberalization, job creation and the skill premium : evidence from the U.S.-Vietnam bilateral trade agreement

2013-04-24T04:00:00.000Z

This paper explores how the expansion of labor-intensive manufacturing exports resulting from the United States-Vietnam Bilateral Trade Agreement in 2001 translated into wages of skilled and unskilled workers and the skill premium in Vietnam through the channel of labor demand. In order to isolate the impacts of trade shock from the effects of other market-oriented reforms, a strategy of exploiting the regional variation in difference in exposure to trade is employed. Using the data on panel individuals from the Vietnam Household Living Standards Surveys of 2002 and 2004, and addressing the issue of endogeneity, the results confirm the existence of a Stolper-Samuelson type effect. That is, those provinces more exposed to the increase in exports experienced relatively larger wage growth for unskilled workers and a decline of (or a smaller increase in) the relative wages of skilled and unskilled workers. During the period 2000-2004, the skill premium increased for Vietnam's economy as a whole in the sample of panel individuals. Thus, the Stolper-Samuelson type effect appears to have mitigated but did not outweigh the impacts of other factors that contributed to the rise in the skill premium.

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.

Foreign wage premium, gender and education : insights from Vietnam household surveys

2013-04-24T04:00:00.000Z

This paper investigates the differential impacts of foreign ownership on wages for different types of workers (in terms of educational background and gender) in Vietnam using the Vietnam Household Living Standards Surveys of 2002 and 2004. Whereas most previous studies have compared wage levels between foreign and domestic sectors using firm-level data (thus excluding the informal sector), one advantage of using the Living Standards Surveys in this paper is that the data allow wage comparison analyses to extend to the informal wage sector. A series of Mincerian earnings equations and worker-specific fixed effects models are estimated. Several findings emerge. First, foreign firms pay higher wages relative to their domestic counterparts after controlling for workers personal characteristics. Second, the higher the individual workers' levels of education, the larger on average are the wage premiums for those who work for foreign firms. Third, longer hours of work in foreign firm jobs relative to working in the informal wage sector are an important component of the wage premium. Finally, unskilled women experience a larger foreign wage premium than unskilled men, reflecting the low earning opportunities for women and a higher gender gap in the informal wage sector.

How to avoid middle income traps ? evidence from Malaysia

2013-04-26T04:00:00.000Z

Malaysia's structural transformation from low to middle income is a success story, making it one of the most prominent manufacturing exporters' in the world. However, like many other middle income economies, it is squeezed by the competition from low-wage economies on the one hand, and more innovative advanced economies on the other. What can Malaysia do? Does Malaysia need a new growth strategy? This paper emphasizes the need for broad structural transformation; that is, moving to higher productivity production in both goods and services. This paper examines productivity growth for Malaysia at the sectoral level, and constructs several measures of the sophistication of goods and services trade, and puts these comparisons in a global context. The results indicate that Malaysia has further opportunities for growth in the services sector in particular. Modernizing the services sector may provide a way out of the middle income trap, and serve as a source of growth for Malaysia into the future.

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.

Different dreams, same bed : collecting, using, and interpreting employment statistics in Sub-Saharan Africa -- the case of Uganda

2013-05-07T04:00:00.000Z

Employment and earnings statistics are the key link between the size and structure of economic growth and the welfare of households, which is the ultimate goal of development policy, so it is important to monitor employment outcomes consistently. A cursory review of employment data for low-income Sub-Saharan African countries shows both large gaps and improbable variation within countries over time and among countries, suggesting that low quality data are routinely reported by national statistics offices. Unfortunately, policies are formed and projects developed and implemented on the basis of these statistics. Therefore, errors of measurement could be having profound implications on the strategic priorities and policies of a country. This paper explains the improbable results observed by using data from Uganda, where the labor module contains variation both within and across surveys, to show the sensitivity of employment outcomes to survey methodology. It finds that estimates of employment outcomes are unreliable if the questionnaire did not use screening questions, as labor force participation will be underestimated. Likewise, surveys that use a seven-day recall period underestimate or potentially misrepresent employment outcomes, owing to seasonality and multiple jobs. Common multivariate analysis applied on household survey data will be affected, as the errors in measurement in the dependent and independent variables will be correlated. Corrections to reduce measurement bias in existing data are tested with the survey data; none are found to be completely satisfactory. The paper concludes that there is a knowledge gap about employment outcomes in Sub-Saharan Africa that will continue unless collection techniques improve.

How can safety nets contribute to economic growth ?

2013-05-07T04:00:00.000Z

The paper provides an up-to date and selective review of the literature on how social safety nets contribute to growth. The evidence is carefully chosen to show how safety nets have the potential to overcome constraints on growth linked to market failures, and is organized into 4 distinct pathways: i) encouraging asset accumulation by changing incentives and by addressing imperfections in financial markets caused by constraints in obtaining credit, and from information asymmetries; overcoming such failures helps households to invest into their human capital or productive assets; ii) failures in insurance markets especially in low income setting; safety nets are assisting in managing risk both ex post and ex ante; iii) safety nets are overcoming failure to create assets and other local economy complementary factors to household-level investments; iv) safety nets are shown to relax political constraints on policy. Safety nets have a dual objective of directly alleviating poverty through transfers to the poor and of triggering higher growth for the poor. However, the trade-off between the dual objectives of equity and growth is not eliminated by the potential for productive safety nets; this remains critical for designing social policies.

A model of gendered production in colonial Africa and implications for development in the post-colonial period

2013-05-08T04:00:00.000Z

This paper proposes a model to analyze the implications of colonial policies for gender inequality in Sub-Saharan Africa. The model emphasizes segmentation of production under complete specialization. It shows that the colonial production model, underpinned by occupational job segregation in the agricultural sector and gender bias in the non-agricultural sector, exacerbated gender inequality by limiting employment opportunities for women outside the realm of home production and subsistence agriculture. Over the past few decades, the resilience of parameters underlying these models of colonial production has heightened the risks of macroeconomic volatility in the region, especially where the structural transformation from low to high-value-added activities has remained elusive.

Jobs, wellbeing, and social cohesion : evidence from value and perception surveys

2013-05-16T04:00:00.000Z

Recent events, including the Arab Revolutions and protest movement of unemployed youths in OECD countries, have contributed to the popular sentiment that access to good jobs is an important driver of social cohesion. While economic dimensions of labor market outcomes are relatively well documented, evidence on the link between social cohesion and employment conditions is still surprisingly scarce. This paper, a background report for the WDR 2013 on Jobs, presents descriptive evidence that illustrates possible linkages between labor market outcomes and social cohesion. The findings suggest that, once one passes the threshold from low to lower middle income countries, formal employment emerges as a determinant of a range of outcomes relating to social cohesion, such as membership in social associations or levels of political activism. There are also indications of an increasing association between work and life satisfaction across higher and lower middle income countries. The paper concludes with a discussion of the study's implications for emerging economies whose labor market and social institutions are still in transition.

Non-farm diversification, poverty, economic mobility and income inequality : a case study in village India

2013-05-20T04:00:00.000Z

This paper assembles data at the all-India level and for the village of Palanpur, Uttar Pradesh, to document the growing importance, and influence, of the non-farm sector in the rural economy between the early 1980s and late 2000s. The suggestion from the combined National Sample Survey and Palanpur data is of a slow process of non-farm diversification, whose distributional incidence, on the margin, is increasingly pro-poor. The village-level analysis documents that the non-farm sector is not only increasing incomes and reducing poverty, but appears as well to be breaking down long-standing barriers to mobility among the poorest segments of rural society. Efforts by the government of India to accelerate the process of diversification could thus yield significant returns in terms of declining poverty and increased income mobility. The evidence from Palanpur also shows, however, that at the village-level a significant increase in income inequality has accompanied diversification away from the farm. A growing literature argues that such a rise in inequality could affect the fabric of village society, the way in which village institutions function and evolve, and the scope for collective action at the village level. Failure to keep such inequalities in check could thus undermine the pro-poor impacts from the process of structural transformation currently underway in rural India.

The exceptional persistence of India's unorganized sector

2013-05-21T04:00:00.000Z

The transformation of India's unorganized sector is important to its modernization, growth, and attainment of regional economic equality. This paper documents several key facts about India's unorganized sector in manufacturing and services. First, the unorganized sector is large, accounting for more than 99 percent of establishments and 80 percent of employment in manufacturing. Second, the unorganized sector is stubbornly persistent -- it accounted for 81 percent of manufacturing employment in 1989 and 2005. Third, this persistence is not due to particular subsets of industries or states, as most industries and states show limited change in unorganized sector employment shares. Fourth, the degree to which localized unorganized activity exists is important as it is associated with weaker production functions for manufacturing firms. Building from these facts, the paper investigates conditions promoting transformation by state-industry. Decomposition exercises find that both within and between adjustments for state-industries weakly reduce unorganized sector shares. The aggregate persistence instead comes from the covariance term, where fast-growing state-industries witness rising unorganized sector activity. Regressions quantify that growth in the organized sector by state-industry reduces the unorganized sector employment share, but only marginally reduces employment levels in unorganized activity. Analysis of the establishment size distribution highlights that entrepreneurship and larger organized sector plants are most important for transitions in the manufacturing sector, while small establishments play a key role in the services sector.

The labor market impact of mobility restrictions : evidence from the West Bank

2013-05-22T04:00:00.000Z

Using data on Israeli closures inside the West Bank, this paper provides new evidence on the labor market effects of conflict-induced restrictions to mobility. To identify the effects, the analysis exploits the fact that the placement of physical barriers by Israel was exogenous to local labor market conditions and uses a measure of conflict intensity to control for the likely spurious correlation between local unrest, labor market conditions, and the placement of barriers. The study finds that these barriers to mobility have a significant negative effect on employment, wages, and days worked per month. The barriers had a positive impact on the number of hours per working day. These effects are driven mainly by checkpoints while other barriers, such as roadblocks and earth mounds, have a much more limited impact. Only a tiny portion of the effects is due to direct restrictions on workers' mobility, suggesting that these restrictions affect the labor market mainly by depressing firms' production and labor demand. Despite being an underestimation of the actual effects, the overall costs of the barriers on the West Bank labor market are substantial: in 2007, for example, these costs amounted to 6 percent of gross domestic product. Most of these costs are due to lower wages, thus suggesting that the labor market has adjusted to the restrictions more through prices than quantities.
