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.
Publication(Alex Publishers, 2017) Sanghi, Apurva ; Burns, Andrew ; Djiofack, Calvin ; Prihardini, Dinar ; Dissanayake, Jagath ; Hollweg, ClaireThis report assesses the future impact of two dynamically transforming economies – China and India – on Russia’s economy. China is slowing down and rebalancing its economy whereas India is rapidly expanding. What does this hold for Russia? The report begins with a snapshot of findings, followed by eight chapters. Chapter one motivates the topic and identifies analytical and empirical gaps that this report fills. Chapter two examines the current pattern of trade between Russia and the two countries, and it discusses how important – or not – China and India’s economies are for Russia. Chapter three follows by summarizing the results of three complementary approaches for measuring Russia’s trade potential with China and India (and also the rest of the world). Chapter fourth intuitively describes the customized methodology developed for this report; its major caveats and assumptions, and its possible extensions (technical details, for those interested, are in the annexes). Chapter fifth outlines four plausible scenarios of the potential impact on Russia of changes in China and India, and chapter sixth presents the results. Chapter seventh explores the sensitivity of results to changes key in assumptions. Finally, chapter eighth concludes with emerging policy implications for Russia.
