The analysis in this report confirms the findings of previous studies that trade liberalization improves aggregate welfare and is in the long run associated with higher employment and wages. The analysis addresses a major gap in the literature, which has heretofore provided limited evidence about the trade-related adjustment costs faced by workers in developing countries and how they are affected by mobility costs. Labor market frictions reduce the potential gains from trade reform. For a tariff reduction in a given sector, the resulting change in relative prices raises real wages in some sectors and reduces them in the liberalized sector. The emerging wage gaps lead to labor reallocation. But workers typically incur costs to change jobs; the higher the mobility costs, the slower the transition to the new labor market steady state. Workers sticky feet result in foregone welfare gains from trade. This report presents an estimation strategy for capturing mobility costs when only net flows of workers between industries are observed, generating cross-country estimates for 47 developed and developing countries. The basic analytical approach is then refined to take advantage of micro-level data on worker transitions and wages when gross flows can be observed to derive mobility cost estimates that account for sector and formality status. These cost estimates are used to model the dynamic paths of labor reallocation between sectors and in and out of the labor force, the associated wage paths, and the resulting labor adjustment costs. The main findings of the report are that: labor mobility costs in developing countries are high; foregone trade gains due to frictions in labor mobility can also be substantial; workers bear the brunt of adjustment costs; mobility costs and labor market adjustments to trade-related shocks vary by industry, firm type, and worker type; entry costs are significantly higher for formal than for informal employment; trade reforms increase economy-wide wages and employment; and workers displaced by plant closings are likely to face relatively long adjustment periods. The findings provide insights that could be helpful to policymakers hoping to mitigate negative short-term consequences of trade liberalization and facilitate labor adjustment."

Recognizing that services affect the ability of countries and their firms to compete on international markets, the World Bank's Trade and Regional Integration Unit has developed an extensive work program to promote the performance of countries' domestic services sectors, including services trade. Services for Trade Competitiveness presents selected applications of new methodologies that were developed to assess the competitiveness of countries' services sectors, discern the types of barriers to services that exist in the regulatory environment, and identify the resulting policy implications. Its assessments are designed for a wide audience, including policy makers in developing countries and development practitioners in international organizations, policy-making institutions, and academia. The purpose of this book is to help developing countries make informed policy choices to increase their chances of benefiting from the increasing prominence of services in international trade
