We document a transmission channel from credit conditions to capital accumulation via investment wedges. Using a simple multi-industry model of production and investment, we measure these wedges at the 4-digit industry level from Mexican manufacturing and show that they account for most of the changes in aggregate capital over time. We also find a robust relation between the wedges and financial variables: credit and interest rates, also measured at the industry level.
