Publication(Washington, DC: World Bank, 2014-06-17) Hollweg, Claire H. ; Lederman, Daniel ; Rojas, Diego ; Ruppert Bulmer, ElizabethThis report analyzes the paths by which developing country labor markets adjust to permanent trade-related shocks. Trade shocks can bring about reallocation of labor between industries, but the presence of labor mobility costs implies economy-wide losses because they extend the period of economic adjustment. This report focuses primarily on the adjustment costs faced by workers after a trade shock, because of magnitude and welfare implications and policy relevance. From a policy viewpoint, understanding the relative magnitudes of labor mobility and adjustment costs can help policymakers design trade policies that are consistent with employment objectives, can be complemented by labor policies, or support programs to facilitate labor transitions, or both. To complement and validate the analysis based on structural choice models, the study designed a distinct empirical approach using reduced-form econometric estimation strategies. This approach examines the impact of structural reforms and worker displacement on labor market outcomes. This makes it possible to estimate the time required to adjust to a trade-related shock, but does not assume the rigid underlying relationship inherent in structural models. This report is organized as follows: chapter one gives introduction. Chapter two presents evidence from the literature on the relative magnitude of labor adjustment costs borne by workers and by firms. Chapter three presents a new database of country-level labor mobility cost estimates for both developing and developed economies. Chapter four showcases country case studies in which labor mobility costs vary by industry, firm size, and worker type (for example, informal versus. formal). Chapter five analyzes the impact of structural reforms on aggregate labor market outcomes across countries and the effect of worker displacement due to plant closings on the employment outcomes of individual workers in Mexico. Chapter six concludes with a summary of the main findings about the labor adjustment costs associated with trade-related shocks and a discussion of policy responses internationally.
Publication(World Bank Group, Washington, DC, 2014-11) Hollweg, Claire H. ; Lederman, Daniel ; Mitra, DevashishThis paper explores the impact of structural reforms on a comprehensive set of macro-level labor-market outcomes, including the unemployment rate, the average wage index, and overall and female employment levels and labor force participation rates. Together these outcome variables capture the overall health of the labor market and the aggregate welfare of workers. Yet, there seems to be no other comprehensive empirical investigation in the existing literature of the impact of structural reforms at the cross-country macro level on labor-market outcomes other than the unemployment rate. Data were collected from a variety of sources, including the World Bank World Development Indicators, the International Monetary Fund International Financial Statistics, and the International Labor Organization Key Indicators of the Labor Market. The resulting dataset covers up to 88 countries, the majority being developing, for 10 years on either side of structural reforms that took place between 1960 and 2001. After documenting the average trends across countries in the labor-market outcomes up to 10 years on either side of each country s structural reform year, the authors run fixed-effects ordinary least squares as well as instrumental variables regressions to account for the likely endogeneity of structural reforms to labor-market outcomes. Overall the results suggest that structural reforms lead to positive outcomes for labor. Unlike related literature, the paper does not find conclusive evidence on unemployment. Redistributive effects in favor of workers, along the lines of the Stolper-Samuelson effect, may be at work.
Publication(World Bank, Washington, DC, 2015-06) Cali, Massimiliano ; Hollweg, Claire H. ; Ruppert Bulmer, ElizabethIncreasing the trade integration of developing countries can make a vital contribution to boosting shared prosperity, but it also exposes producers and consumers to exogenous shocks that alter relative prices, sometimes positively and sometimes negatively. This paper discusses the short-run effects of trade-related shocks on households to capture the potential welfare impact on the poor. The discussion explores the channels through which trade shocks are transmitted to households in the bottom of the income distribution, namely through consumption, household production, and market-based labor activities. The degree to which price shocks are passed through from borders to point of sale is a key determinant of the gains from trade and the ultimate welfare impact. Trade changes in agriculture directly affect households through their consumption basket. Lower agricultural prices reduce the cost of consumables, but these welfare gains may be offset by lower earnings for households that produce these same goods. Poorer households tend to be net consumers of agricultural products, suggesting a net welfare gain, but agricultural wage workers could suffer from wage cuts. Because poorer households tend to consume relatively fewer nonagricultural products, that is nonessentials, any trade-related shocks to prices of nonagricultural product are likely to be transmitted via labor channels. Despite significant evidence that nonagricultural trade reform ultimately leads to job creation and enhanced productivity, the short-run effects can be mixed. The costs incurred by workers to transition to new jobs slow the adjustment of the economy to a new steady state. Labor mobility costs, which tend to be higher in developing countries and for unskilled workers, reduce the potential gains to trade by diverting labor market adjustment from its most efficient path.

The resulting Labor Content of Exports database allows the examination of the direct contribution of labor to exports as well as the indirect contribution via other sectors of the economy for skilled and unskilled labor. The analysis of the new data sets documents several new findings. First, the global share of labor value added in exports has been declining globally since 1995, but it has increased in low-income countries. Second, in line with the standard Hecksher-Ohlin trade model, the composition of labor directly contained in exports is skewed toward skilled labor in high-income countries relative to developing countries. However, that is not the case for the indirect labor content of exports. Third, manufacturing exports are a key source of labor demand in other sectors, especially in middle- and low-income countries. And the majority of the indirect demand for labor spurred by exports is in services sectors, whose workers are the largest beneficiaries of exporting activities globally. Fourth, differences in the labor value added in exports share across developing countries appears to be driven more by differences in the composition of exports rather than in sector labor intensities. Finally, average wages typically increase rapidly enough with the process of economic development to more than compensate the loss in jobs per unit of exports. The paper also includes the necessary information to build the Labor Content of Exports database from the original raw data, including stata do-files and matlab files, as well as descriptions of the variables in the data set.
Publication(World Bank, Washington, DC, 2020-10) Hollweg, Claire H. ; Ong Lopez, AnneUsing firm-level data for Georgia, the paper estimates the quasi-elasticity of employment and wages with respect to the share of exports in total sales, to explore whether changes in the structure of sales (exporting versus selling to the domestic market) matter for labor market outcomes. The methodology uses exogenous fluctuations in exchange rates combined with firms' initial exposure to various markets as instrumental variables to identify a causal effect. The results differentiate employment levels and average wages by gender and consider whether export destination or the competiveness of economies matters for the magnitude of this elasticity. The data are from the National Statistics Office of Georgia Statistics Survey of Enterprises merged with customs data for 2006-17. The instrumental variables regression results show that the act of exporting improves female employment but reduces overall average wages and female wages. Increasing exports to the European Union as well as high-income countries drives this positive result for female employment, whereas exporting to upper-middle-income countries is found to have a negative relationship with female employment.
Publication(World Bank, Washington, DC, 2018-07-16) Farole, Thomas ; Hollweg, Claire ; Winkler, DeborahThe paper is structured in six further sections following this introduction. Section two develops a conceptual framework, and reviews the literature on the relationship between trade integration and labor market outcomes. Section three outlines the empirical framework and data used in the analysis. Section four presents results on the relationship between overall trade integration (through exports) and labor market outcomes. Section five then focuses specifically on GVC trade, and assesses the relationship between labor market outcomes and GVC integration as a buyer and as a seller. Section six tests if select policy indicators mediate these relationships between trade integration and labor market outcomes. Finally, section seven concludes, with a summary of results and areas for future research.
Publication(World Bank, Washington, DC, 2019-09) Cali, Massimiliano ; Hidayat, Taufik ; Hollweg, Claire H.The ability of workers to transition to a new job is crucial to determine the resilience of an economy to (positive or negative) shocks. This paper provides new evidence on the factors that affect labor mobility by using labor data on Indonesia, one of countries with the higher estimated labor mobility costs. To do so it investigates correlates of the probability of an individual finding a job after a negative labor market shock, as well as of the duration of job search. The results show that higher housing prices are associated with higher mobility costs, suggesting that housing benefits or policies that increase the supply of housing may help reduce mobility costs in Indonesia. More generally, public expenditure on infrastructure seems to reduce labor mobility costs, particularly in urban areas, consistently with a reduction in transaction costs – such as urban transport. The results also highlight that formal institutional mechanisms such as job advertisements do not appear to work effectively to help labor mobility in Indonesia, suggesting the need to re-think active labor market policies. On the other hand, minimum wage level – a key outcome of labor market policy - does not appear to affect labor mobility. Labor mobility costs seem higher in urban areas, which could indicate a lower opportunity cost of joblessness than in rural area, employment composition skewed towards sectors with higher mobility costs and/or large congestion costs that negatively affect labor mobility. On the other hand, the general female penalty in labor mobility is less accentuated in urban areas, which may be the result of sectoral composition and/or less discriminatory cultural norms than in rural areas.
