    Sticky Feet : How Labor Market Frictions Shape the Impact of International Trade on Jobs and Wages
    (Washington, DC: World Bank, 2014-06-17) Hollweg, Claire H. ; Lederman, Daniel ; Rojas, Diego ; Ruppert Bulmer, Elizabeth
    This 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.

    Seeking Shared Prosperity through Trade
    (World Bank, Washington, DC, 2015-06) Cali, Massimiliano ; Hollweg, Claire H. ; Ruppert Bulmer, Elizabeth
    Increasing 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 Labor Content of Exports in South Africa and Botswana: A Preliminary Exploration
    (World Bank, Washington, DC, 2015-01) Calì, Massimiliano ; Hollweg, Claire
    The LACEX dataset has been recently assembled to compute the (direct and indirect) value of the compensation of employees linked to exports for each sector/country/year. The data has been computed on the basis of a panel of global input-output data spanning intermittent years from 1995 to 2007 from the Global Trade Analysis Project (GTAP). This represents a form of social accounting data - a variation on the social accounting matrix (SAM) where incomes are shown in the rows of the SAM while expenditures are shown in the columns. The structure of the data provides a comprehensive and consistent record of national income accounting relationships between different sectors and regions, including intermediate and final demand linkages. This structure of the dataset allows one to obtain the value added content of final output and exports, including its compensation of employees’ component. That includes both the direct and indirect compensation, based on the backward linkages of each sector with the rest of the economy. In order to obtain these labor value added measures, two intermediate multiplier matrixes need to be calculated. The first is the Leontief inverse matrix, which measures the inputs contained in a unit of final output. This matrix contains both direct and indirect inputs. Next, one needs to calculate a matrix which has the compensation of employees’ shares of total output. Using these two matrixes as multipliers one can obtain the compensation of employees’ shares of exports and final outputs. These shares are also split between skilled and unskilled workers.

    How Does Participation in Value Chains Matter to African Farmers?
    (World Bank, Washington, DC, 2018-07) Dihel, Nora ; Goswami, Arti Grover ; Hollweg, Claire H. ; Slany, Anja
    Trade and participation in global value chains can play a key role in economic diversification and development. This paper deepens the discussion about productivity growth and upgrading in agriculture in Africa, and the role of national, regional, and international value chains in supporting such structural change. The analysis in this report is based on quantitative and qualitative surveys undertaken in 2016 in Ghana, Kenya, and Zambia, where 3,935 farmers, 60 aggregators, and 56 buyers in the maize, cassava, and sorghum value chains were interviewed in the three countries. The descriptive results show that farmers who were on a contract saw greater structural transformation; higher output; and better access to seeds, fertilizers, pesticides, technology, and extension services compared with farmers who were not on a contract. To identify more robustly the link between value chain participation and contract farming with productivity and upgrading, the paper looks at the relationship using a variety of empirical methodologies, ranging from ordinary least squares and probit regressions to propensity score matching. Based on the empirical evidence, the hypothesis that value chain participation leads to structural transformation cannot be confirmed. The paper does find evidence that formal or informal contractual arrangements that regulate the provision of inputs to production, such as fertilizer, technology, extension services, and market information, positively affect upgrading. It remains nevertheless important to understand the impact of government policies on the emergence of value chains given that value chains support contractual arrangements.

    The Labor Content of Exports Database
    (World Bank, Washington, DC, 2016-03) Cali, Massimiliano ; Francois, Joseph ; Hollweg, Claire H. ; Manchin, Miriam ; Oberdabernig, Doris Anita ; Rojas-Romagosa, Hugo ; Rubinova, Stela ; Tomberger, Patrick
    This paper develops a novel methodology to measure the quantity of jobs and value of wages embodied in exports for a large number of countries and sectors for intermittent years between 1995 and 2011. 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.
