This paper develops a DSGE model with downward nominal wage rigidity, in which aggregate price and productivity dynamics are exogenously determined by independent Brownian motions with drift. As a result, the long-run expected value of unemployment depends positively on the drift coefficients...

This paper builds up a simple New Keynesian model and revisits the relationship between unemployment and in ation in the long-run. It finds that when the labor market is affected by downward nominal wage rigidity, this relationship goes beyond the tradeoff between the first moments of...

We examine the mean-reverting properties of real exchange rates, by comparing the unit root properties of a group of international real exchange rates with two groups of intra-national real exchange rates. Strikingly, we find that while the international real rates taken as a group appear...

This paper argues that typical applications of panel unit root tests should take possible nonstationarity in the volatility process of the innovations of the panel time series into account. Nonstationarity volatility arises for instance when there are structural breaks in the innovation...

This paper studies the impact of the level and volatility of the commodity terms of trade on economic growth, as well as on the three main growth channels: total factor productivity, physical capital accumulation, and human capital acquisition. We use the standard system GMM approach as well as...

Do countries with higher levels of national IQ experience less volatility in the growth of real economic output compared with lower-IQ countries? This issue has not been addressed. Using a large sample of countries, a simple bivariate correlation indicates that IQ and economic volatility are...
