Blume and Easly [1992] show that if agents have the same savings rule, an expected discounted logarithmic utility maximizer with correct beliefs will dominate. If no agent adopts this rule, then agents with incorrect beliefs, but equally averse to risk as logarithmic utility maximizers, may...

This paper studies the welfare effects of monetary and fiscal policy rules, in a dynamic general equilibrium model with sticky prices. The model features capital accumulation and endogenous labor effort, and exogenous productivity shocks. Government purchases are valued positively by the private...

We evaluate the case for perfect price (inflation) stabilization in a New Keynesian (NNS) model that includes capital accumulation, a variety of shocks, a monetary and an imperfect competition distortion. In such a model, price rigidity may provide the monetary authorities with an opportunity to...

In this paper we combine the assumption that the consumption function is concave with an AK production function. We show that the set of equilibrium steady-state growth rates is an interval. Then we note that when they exist, unegalitarian equilibria are characterized by higher rates of growth...

The recent works of Gali and Gertler (1999) and Gali, Gertler, and Lopez-Salido (2001) provided evidence supporting the NKPC for the United States and the euro area. However, several econometric problems have been discussed in the literature on the empirical relevance of their results (among...

This paper tests for long run PPP using a nonstationary panel regression framework that can accommodate both permanent and temporary shocks. It also uses the common correlated estimator of Pesaran (2003a) to take account of cross sectional dependence. The PPP null in our framework is a unit...

In economic theory, there exist many important problems whose mathematical formulation is a function relating the current value of a certain state variable to its (accurately forecast) future value. The most widely studied class of such problems is the Overlapping generations (OLG) models in...

We deal with new product preannouncements in markets where customer preferences are unknown and highly unstable, as would be the case with disruptive product innovations. Our analysis is focused on the tradeoff between the firms incentive to influence consumer preferences via preannouncements...

In this paper I introduce human capital accumulation with time-to-build technology into a real business cycle model. The only driving force is an exogenous shock affecting the long-run equilibrium level of productivity. A positive shock is assumed to generate a rise in the long-run equilibrium...
