This paper builds a model of sovereign debt in which default risk, interest rates, and debt depend not only on current fundamentals but also on news about future fundamentals.

We investigate the role of macroprudential policies in mitigating liquidity traps driven by deleveraging, using a simple Keynesian model. When constrained agents engage in deleveraging, the interest rate needs to fall to induce unconstrained agents to pick up the decline in aggregate demand....

Out-of-sample forecasting tests of DSGE models against time-series benchmarks such as an unrestricted VAR are increasingly used to check a) the specification b) the forecasting capacity of these models. We carry out a Monte Carlo experiment on a widely-used DSGE model to investigate the power of...

"This paper provides evidence of a problem with the influential testing and assessment of Solow's (1956) growth model proposed by Mankiw et al.

The choice of an appropriate social discount rate for cost–benefit analysis of public projects has long been a contentious issue and subject to intense debate among economists. This debate has gained new impetus from the recent discussions on the economics of climate change. The purpose of...

This paper presents a theoretical model to analyze the effects of technology change on growth rates of income and human capital in the uncertain environments of technology. The uncertainty comes from two sources; the possibility of a technology advance and the characteristics of new...

This paper presents a theoretical model and empirical evidence to explain the observation that a country in which the level of technology approaches the technology frontier tends to rely more on technology creation than adoption, and to invest more in basic research than in development. The...
