Structural reform, institutions and earnings: Evidence from the formal and informal sectors in urban Peru

Reforms undertaken in Peru in the early 1990s might have resulted in a slight reduction of the informal sector. Costs associated with becoming and staying informal, and benefits of becoming formal might have increased. This, when a legalistic definition of informality is used. Earnings differentials between formal and informal self-employed workers are negligible although they persist between formal and informal salaried workers. Skilled workers are more likely to be found in the formal sector and informal wage earners tend to be younger and less skilled. The earnings generating process for both the formal and the informal self-employed workers is similar.

Ethnicity and Earnings in a Mixed‐Race Labor Market

This study examines the relationship between earnings and racial differences in a context in which various races have coexisted and mixed during several centuries, as is true in many parts of the postcolonial world and specifically urban Peru. Coarse indicators of racial differences do not suffice in capturing this relationship; therefore, we introduce a score‐based procedure of white and indigenous racial intensities that allows us to approximate these mixed racial heritages. We introduce a score‐based procedure of white and indigenous racial intensities that allows us to approximate the heterogeneity within the mestizo population. We construct two types of indicators of racial intensities using a score‐based procedure: a single‐dimensional indicator of degrees of whiteness and a two‐dimensional indicator combining degrees of both whiteness and indigenousness. This second indicator allows us to study nonlinearities in earning differences across mixed white and indigenous racial characteristics. Our estimates from a semiparametric model show evidence of a race premium for whiteness on earnings, statistically significant among wage earners but not among the self‐employed. These results may be consistent with a story of employer discrimination.

Is Labor Income Responsible for Poverty Reduction? A Decomposition Approach

Demographics, labor income, public transfers, or remittances: Which factor contributes the most to observed reductions in poverty? Using counterfactual simulations, this paper accounts for the contribution labor income has made to the observed changes in poverty over the past decade for a set of 16 countries that have experienced substantial declines in poverty. In contrast to methods that focus on aggregate summary statistics, the analysis generates entire counterfactual distributions that allow assessing the contributions of different factors to observed distributional changes. Decompositions across all possible paths are calculated so the estimates are not subject to path-dependence. The analysis shows that for most countries in the sample, labor income is the most important contributor to changes in poverty. In ten of the countries, labor income explains more than half of the change in moderate poverty; in another four, it accounts for more than 40 percent of the reduction in poverty. Although public and private transfers were relatively more important in explaining the reduction in extreme poverty, more and better-paying jobs were the key factors behind poverty reduction over the past decade.

What is behind the decline in poverty since 2000 ? evidence from Bangladesh, Peru and Thailand

This paper quantifies the contributions of different factors to poverty reduction observed in Bangladesh, Peru and Thailand over the last decade. In contrast to methods that focus on aggregate summary statistics, the method adopted here generates entire counterfactual distributions to account for the contributions of demographics and income from labor and non-labor sources in explaining poverty reduction. The authors find that the most important contributor was the growth in labor income, mostly in the form of farm income in Bangladesh and Thailand and non-farm income in the case of Peru. This growth in labor incomes was driven by higher returns to individual and household endowments, pointing to increases in productivity and real wages as the driving force behind poverty declines. Lower dependency ratios also helped to reduce poverty, particularly in Bangladesh. Non-labor income contributed as well, albeit to a smaller extent, in the form of international remittances in the case of Bangladesh and through public and private transfers in Peru and Thailand. Transfers are more important in explaining the reduction in extreme compared with moderate poverty.

Bundling Services and Household Welfare in Developing Countries: The Case of Peru

Using panel data for Peru for 1994-2000, the authors find that when households receive two, or more services jointly, the welfare increases as measured by changes in consumption are larger than when services are provided separately. The increases appear to be more than proportional, as F-tests on the coefficients of the corresponding regressors confirm. Thus, the authors find that bundling services may help realize welfare effects.

Pending Issues in Protection, Productivity Growth, and Poverty Reduction

This paper selectively synthesizes much of the research on Latin American and Caribbean labor markets in recent years. Several themes emerge that are particularly relevant to ongoing policy dialogues. First, labor legislation matters, but markets may be less segmented than previously thought. The impetus to voluntary informality, which appears to be a substantial fraction of the sector, implies that the design of social safety nets and labor legislation needs to take a more integrated view of the labor market, taking into account the cost-benefit analysis workers and firms make about whether to interact with formal institutions. Second, the impact of labor market institutions on productivity growth has probably been underemphasized. Draconian firing restrictions increase litigation and uncertainty surrounding worker separations, reduce turnover and job creation, and poorly protect workers. But theory and anecdotal evidence also suggest that they, and other related state or union induced rigidities, may have an even greater disincentive effect on technological adoption, which accounts for half of economic growth. Finally, institutions can affect poverty and equity, although the effects seem generally small and channels are not always clear. Overall, the present constellation of labor regulations serves workers and firms poorly and both could benefit from substantial reform.

Bundling of Basic Public Services and Household Welfare in Developing Countries: An Empirical Exploration for the Case of Peru

Using panel data for Peru for the period 1994–2000, we found that increases in household welfare, as measured by changes in consumption, are larger when households receive two or more services jointly than when services are provided separately. Such increases appear to be more than proportional, as F-tests on the coefficients of the corresponding regressors confirm. Thus, we found that bundling of services may help realize welfare effects. This finding is particularly robust in the case of urban areas.
