This paper constructs several models in which, unlike the standard neoclassical growth model, positive news about future technology generates an increase in current consumption, hours and investment. These models are said to exhibit procyclical news shocks. We find that all models that exhibit...

Many new technologies display long adoption lags, and this is often interpreted as evidence of frictions inconsistent with the standard neoclassical model. In this paper we study the diffusion of the tractor in American agriculture between 1910 and 1960 – a well known case of slow diffusion...

This paper develops a monetary model with taxes to account for the time-varying effects of energy shocks on output and hours worked in post-World War II U.S. data. In our model, the real effects of an energy shock are amplified when the monetary authority responds to that shock by changing its...

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....

The case against patents can be summarized briefly: there is no empirical evidence that they serve to increase innovation and productivity. There is strong evidence, instead, that patents have many negative consequences

This paper provides a theory to explain the paradoxical features of the great housing boom in China — the persistently faster-than-GDP housing price growth, exceptionally high capital returns, and excessive vacancy rates. The expectation that high capital returns driven mainly by resource...

Many economic activities are organized as partnerships. These ventures are formed with capital contributions by partnership members who obtain a share of ownership in exchange. The design of the partnership dictates how much of the profits is distributed among the members and how much is...

This paper develops the theory of multi-step ahead forecasting for vector time series that exhibit temporal nonstationarity and co-integration. We treat the case of a semi-infinite past by developing the forecast filters and the forecast error filters explicitly. We also provide formulas for...

We estimate a DSGE model with (S,s) inventory policies. We find that (i) taking inventories into account can significantly improve the empirical fit of DSGE models in matching the standard business-cycle moments (in addition to explaining inventory fluctuations); (ii) (S,s) inventory policies...

The two channels of default on unsecured consumer debt are (i) bankruptcy, which legally grants partial or complete removal of unsecured debt under certain circumstances, and (ii) delinquency, which is informal default via nonpayment. In the United States, both channels are used routinely. This...
