Summary, Etc.  

요약The first chapter of this dissertation quantifies the aggregate unemployment implications of a reallocation of labour demand. Workers displaced by the reallocation of labour demand across industries suffer persistent earnings losses, in a large part due to higher unemployment risk. To study the macro implications I develop a search and matching model with multiple industries and industry specific skill that is calibrated to the US economy. In the model a reallocation shock leads to up to a 0.8 percentage points rise in unemployment. The combination of industry specific skill and the substitutability between workers of different skill levels are key to this result. Chapter 2 is the product of joint work with Matias Bayes-Erazo and analyzes the joint dynamics of labour and capital in economies with heterogeneous firms. We develop a model of lumpy capital adjustment with frictional hiring that helps resolve the tension between existing models of aggregate investment and the latest microeconomic evidence on capital and labor adjustment. Investment models struggle to replicate the lumpiness of investment at the microeconomic level and the sluggishness at the aggregate level. Unlike existing models of investment, our model is consistent with the well-documented lumpiness of firm investment at the micro level and the responsiveness of aggregate investment to changes in the cost of capital. The third chapter is joint work Laura Murphy. We study how demographic changes in the US affect men's lifetime incomes through career spillovers. American men's lifetime median incomes have followed a hump shaped pattern: rising with each cohort entering the labour market from the late 1950s until the 1970s, and subsequently falling. The start of decline coincides with the entry of the baby boomers who represent a structural break in the size of incoming cohorts. The availability of higher-compensated management tasks increases with the number of lower ranked (younger) workers. So, a larger cohort of workers will increase (decrease) the opportunities of their predecessors(successors), in contrast to the symmetric effect predicted by traditional models. We utilize a simple model to show cross-cohort differences in promotions to higher rank jobs can account for the shape of lifetime median incomes observed in the data. We also show the promotion mechanism is consistent with several other cross-cohort empirical facts.
