This paper offers a plausible explanation for the close link between oil prices and aggregate macroeconomic performance in the 1970s. Although this link has been well documented in the empirical literature, standard economic models are not able to replicate this link when actual oil prices are...

Are asset prices unduly volatile and often detached from their fundamentals? Does the bursting of financial bubbles depress the real economy? This paper addresses these issues by constructing a DSGE model with speculative bubbles. We characterize conditions under which storable goods, regardless...

We formalize the Keynesian insight that aggregate demand driven by sentiments can generate output fluctuations under rational expectations. When production decisions must be made un- der imperfect information about aggregate demand, optimal decisions based on sentiments can generate stochastic...

This paper develops an analytically tractable Bewley model of money featuring capital and financial intermediation. It is shown that when money is a vital form of liquidity to meet uncertain consumption needs, the welfare costs of inflation can be extremely large. With log utility and parameter...

This paper uncovers Taylor rules from estimated monetary policy reactions using a structural VAR on U.S. data from 1959 to 2009. These Taylor rules reveal the dynamic nature of policy responses to different structural shocks. We find that U.S. monetary policy has been far more responsive over...

Empirical evidence suggests that fast-growing economies tend to have not only high saving rates but also low interest rates. This evidence is difficult to reconcile with standard explanations about the positive linkages between saving and growth. These explanations rely either on high saving to...

The causal relationship between growth and fixed capital formation is reexamined. Our findings are in sharp contrast with the earlier findings by Blomstrom et al. (1996) that capital formation does not contribute to economic growth. However, our findings also reject the conventional wisdom...

Firm-level investment is lumpy and volatile but aggregate investment is much smoother and highly serially correlated. These different patterns of investment behavior have been viewed as indicating convex adjustment costs at the aggregate level but non-convex adjustment costs at the firm level....

China’s average household saving rate is one of the highest in the world. One popular view attributes the high saving rate to fast rising housing prices and other costs of living in China. This article uses simple economic logic to show that rising housing prices and living costs per se cannot...
