We study how financial frictions amplify labor supply shocks in a macroeconomic model with occasionally binding financing constraints. Workers supply labor to entrepreneurs who borrow to purchase factors of production. Borrowing capacity is restricted by the value of capital, generating a pecuniary externality when financing constraints bind. Additionally, there is a distributive externality operating through wages. The planner’s allocation can be decentralized with two instruments: a credit tax/subsidy and a labor tax/subsidy. Labor shocks, such as the COVID-19 shock, amplify the policy responses, which critically depend on whether financing constraints bind or not.
This paper documents the determinants of real oil price in the global market based on
SVAR model embedding transitory and permanent shocks on oil demand and supply as
well as speculative disturbances. We find evidence of significant differences in the
propagation mechanisms of transitory versus permanent shocks, pointing to the
importance of disentangling their distinct effects. Permanent supply disruptions turn out to
be a bigger factor in historical oil price movements during the most recent decades, while
speculative shocks became less influential.
We investigate theoretically and empirically how exporters adjust their markups across destinations depending on bilateral distance, tariffs, and the quality of their exports. Under the assumption that trade costs are both ad valorem and per unit, our model predicts that markups rise with distance and fall with tariffs, but these effects are heterogeneous and are smaller in magnitude for higher quality exports. We find strong support for the predictions of the model using a unique data set of Argentinean firm-level wine exports combined with experts wine ratings as a measure of quality.
