In this paper, I argue that the answer depends crucially on how much exporters vertically differentiate in response to foreign competition and study the consequences of international trade on welfare of consumers across the income distribution under endogenous vertical differentiation on the supply side. I develop a structural model in which consumer demand for higher-quality goods is non-homothetic in income and firms endogenously choose the quality of their products. The model can be brought to the data using random coefficients demand estimation techniques and I infer demand and supply parameters for 7,000 highly disaggregated products. I find that competition and market structure strongly influence the quality decisions of firms and therefore affect the measured income elasticity of the products they produce. International trade reduces inequality in consumer welfare, but the effect is overstated by about one third when supply side responses are not taken into account. Trade Shocks and Attentive Voting: Evidence from U.S. Local Labor Markets Do voters respond to trade shocks? And can legislators influence voter responses through their standpoints on free trade? In this paper I address these questions using the rise of China as a natural experiment that created substantial geographic variation in the U.S. regarding exposure to trade shocks. I find that voters do respond to incumbents’ ideology, with mod2

erate congressmen being punished and extreme ones actually benefiting from adverse labor market shocks induced by offshoring. Chinese import competition had similar effects but with incumbents being generally punished. Incumbent presidents lose votes in both the 1990s and 2000s and to a larger extent than congressmen, consistent with presidents being viewed as rather moderate and trade policy being rather a national than local matter. I also find a general shift to the left in areas that experienced trade shocks, but whether or not these affect vote shares or ideology scores depends significantly on the type of trade shock. An Rcpp Code for the Estimation of Discrete Choice Random Coefficients Models of Consumer Demand In this paper, I provide a code for the estimation of discrete choice random coefficients models written in Rcpp, using only freely available open source software. The code is particularly designed for applications in which demand for a large number of products needs to be simultaneously estimated. Using C++ instead of R for certain parts results in substantial speed gains, especially when evaluating Jacobian and Hessian matrices during optimization.
