Lending frictions and nominal rigidities: Implications for credit reallocation and TFP

In most modern recessions there is a sharp increase in job destruction and a mild to moderate decline in job creation, resulting in unemployment. The Great Recession was marked by a significant decline in job creation particularly for young firms in addition to the typical increase in destruction. As a result job reallocation fell. In this paper, we explicitly propose a mechanism for financial shocks to disproportionately affect young (typically) smaller firms via credit contracts. We investigate the particular roles of credit frictions versus nominal rigidities in a New Keynesian model augmented by a banking sector characterized by search and matching frictions with endogenous credit destruction. In response to a financial shock, the model economy produces large and persistent increases in credit destruction, declines in credit creation, and an overall decline in reallocation of credit among banks and firms; total factor productivity declines, even though average firm productivity increases, inducing unemployment to increase and remain high for many quarters. Credit frictions not only amplify the effects of a financial shock by creating variation in the number of firms able to produce they also increase the persistence of the shock for output, employment, and credit spreads. When pricing frictions are removed, however, credit frictions lose some of their ability to amplify shocks, though they continue to induce persistence. These findings suggest that credit frictions combined with nominal rigidities are a plausible transmission mechanism for financial shocks to have strong and persistent effects on the labor market particularly for loan dependent firms. Moreover, they may play an important role in job reallocation across firms.
