Abstract

We study how financial frictions affect the importance of trend productivity shocks for macroeconomic fluctuations. Using long-run data from 17 small open economies (SOEs), we compare two variants of a workhorse SOE real business cycle model featuring a debt-elastic interest rate (DEIR), a measure of financial frictions. The first variant estimates the DEIR parameter, while the second fixes it to 0.001, effectively abstracting from financial frictions. On average, ignoring financial frictions doubles the contribution of trend shocks to output fluctuations. This suggests that a proper assessment of the quantitative effects of trend shocks requires reasonable DEIR values.
