We construct a model to capture the Keynesian idea that production and employment decisions are based on expectations of aggregate demand driven by sentiments and that realized demand follows from the production and employment decisions of firms. We cast the Keynesian idea into a simple model...

Most empirical studies based on U.S. data suggest that the fiscal multiplier is less than 1 (e.g., Barro and Redlick, 2011). However, Keynes argued that the multiplier would be the largest when markets have failed to the greatest extent in coordinating economic activities (such as during the...

China’s over 25% aggregate household saving rate is one of the highest in the world. One popular view attributes the high saving rate to fast-rising housing prices in China. However, cross-sectional data do not show a significant relationship between housing prices and household saving rates....

Countries with more developed financial markets (as measured by the private debt- to-GDP ratio) tend to have significantly lower aggregate volatility. This relationship is also highly non-linear starting from a low level of financial development the reduction in aggregate volatility by financial...

A large empirical literature attempts to identify US monetary policy shocks using the effective federal funds rate. This paper compares the time series behavior of the effective federal funds rate to 10 US interest rates with maturities ranging form overnight to 10 years. Using a spectral...

It is widely believed in the literature that inventory fluctuations are destabilizing to the economy. This paper re-assesses this view by developing an analytically-tractable general-equilibrium model of inventory dynamics based on a precautionary stockout-avoidance motive. The model's...

"When monetary policies are endogenous, the conventional VAR approach for detecting the effect of monetary policies is powerless. This paper proposes to test the implication of monetary policies along a different dimension. That implication is to exploit the policy induced exogeneity of...

"Price rigidity is the key mechanism for propagating business cycles in traditional Keynesian theory. Yet the New Keynesian literature has failed to show that sticky prices by themselves can effectively propagate business cycles in general equilibrium. We show that price rigidity in fact can (by...

"One basic problem in business-cycle studies is how to deal with nonstationary time series. The market economy is an evolutionary system. Economic time series therefore contain stochastic components that are necessarily time dependent. Traditional methods of business cycle analysis, such as the...
