A number of explanations for the observed decline in GDP volatility since the mid-1980s have been offered. Valerie Ramey and Daniel Vine (2003a, 2003b) in a couple of recent papers offer the hypothesis that a decline in the persistence of sales is an explanation for the decline in GDP...

As has been widely observed, the volatility of GDP has declined since the mid-1980s compared with prior years. One leading explanation for this decline is that monetary policy improved significantly in the later period. We utilize a cross-section of 2-digit manufacturing and trade industries to...

I analyze the effects of an expected future reduction in government spending on the current level of economic activity. In a closed-economy dynamic general equilibrium setup with nominal rigidities, it is shown that expected future cuts in government spending generate an increase in current GDP....

Why is GDP so much more volatile in poor countries than in rich ones? To answer this question, we propose a theory of technological diversification. Production makes use of different input varieties, which are subject to imperfectly correlated shocks. As in endogenous growth models,...

Most of the reduction in GDP volatility since the 1983 is accounted for by a decline in comovement of output among industries that hold inventories. This decline is not simply a passive byproduct of reduced volatility in common factors or shocks. Instead, structural changes occurred in the...

This paper reports the results of a detailed examination of the hypothesis that improved inventory management and production techniques are responsible for the decline in the volatility of U.S. GDP growth. Our innovations are to look at the data at a finer level of disaggregation than previous...

Using U.S. real-time data, we show that changes in the unemployment rate unexplained by Okun's Law have significant predictive power for GDP data revisions. A positive (negative) error in Okun's Law in real time implies that GDP will be later revised to show less (more) growth than initially...
