Abstract: Abstract I investigate a model of the U.S. economy with nominal rigidities and a financial accelerator mechanism à la Bernanke et al. (Handbook of Macroeconomics, Vol. 1, Elsevier Sci., Chap. 21, pp. 1341–1393, 1999). I calculate total factor productivity (TFP) and monetary policy deviations for the U.S. and quantitatively explore the ability of the model to account for the cyclical patterns of U.S. per capita real private GDP (excluding government), U.S. per capita real private investment, U.S. per capita real private consumption, the share of hours worked per capita, (year-over-year) inflation and the quarterly interest rate spread between the Baa corporate bond yield and the 20-year Treasury bill rate during the Great Moderation. I show that the magnitude and cyclicality of the external finance premium depend nonlinearly on the degree of price stickiness (or lack thereof) in the Bernanke et al. (Handbook of Macroeconomics, Vol. 1, Elsevier Sci., Chap. 21, pp. 1341–1393, 1999) model and on the specification of both the target Taylor (Carnegie-Rochester Conf. Ser. Pub. Policy 39:195–214, 1993) rate for policy and the exogenous monetary shock process. The strong countercyclicality of the external finance premium (the interest rate spread) induces substitution away from consumption and into investment in periods where output grows above its long-run trend as the premium tends to fall below its steady state and financing investment becomes temporarily “cheaper”. The less frequently prices change in this environment, the more accentuated the fluctuations of the external finance premium are and the more dominant they become on the dynamics of investment, hours worked and output. However, these features—the countercyclicality and large volatility of the spread—are counterfactual and appear to be a key impediment limiting the ability of the model to account for the U.S. data over the Great Moderation period.
