Vehicle production has fallen since the beginning of the pandemic recession. We investigate reasons for this decline. Manufacturers in this industry cite insufficient materials, including a lack of semiconductors, as increasingly responsible. Demand seems to be less of an issue. In fact, demand has been strong, and together with accelerating prices and sharply declining inventories, it suggests an insufficient supply of new cars. Our best guess is that the materials shortages and their effects on new car prices will subside within the next six to nine months.

Young adults, ages 25 to 35, who live in the same neighborhoods as their parents experience stronger earnings recoveries after a job displacement than those who live farther away. This result is driven by smaller on-impact wage reductions and sharper recoveries in both hours and wages. We show that geographic mobility, different job search durations, housing transfers, and ex-ante differences between individuals are unlikely explanations. Our fi ndings are consistent with a framework in which some individuals living near their parents face a better wage-offer distribution, though we fi nd no direct evidence of parental network effects.

We add goods-market frictions to a general equilibrium dynamic model with heterogeneous exporting producers and identical importing retailers. Our tractable framework leads to endogenously unmatched producers, which attenuate welfare responses to foreign shocks but increase the trade elasticity relative to a model without search costs. Search frictions are quantitatively important in our calibration, attenuating welfare responses to tariffs by 40 percent and increasing the trade elasticity by 50 percent. Eliminating search costs raises welfare by 1 percent and increasing them by only a few dollars has the same effects on welfare and trade fl ows as a 10 percent tariff.
