International competition and labor market adjustment

How does welfare change in the short- and long-run in high wage countries when integrating with low wage economies like China? Even if consumers benefit from lower prices, there can be significant welfare losses from increases in unemployment and lower wages. I construct a dynamic multi-sector-country Ricardian trade model that incorporates both search frictions and labor mobility frictions. I then structurally estimate this model using cross-country sector-level data and quantify both the potential losses to workers and benefits to consumers arising from China's integration into the global economy. I find that overall welfare increases in northern economies, both in the transition period and in the new steady state equilibrium. In import competing sectors, however, workers bear a costly transition, experiencing lower wages and a rise in unemployment. I validate the micro implications of the model using employer-employee panel data.
