Evidence that real exchange rate dynamics can be described using models which exhibit nonlinear mean reversion has been mounting over the past decade. This article attempts to better understand the shape of real exchange rate nonlinearity through the use of the Smooth Transition Autoregressive...

Fiscal sustainability is one of the most pressing policy issues of our time. Yet it remains difficult to quantify. Official debt is plagued with a number of measurement difficulties since its measurement reflects the choice of words, not policies. And forming the fiscal gap-the imbalance in the...

We characterize and demonstrate a solution method for an optimal commodity (sales) tax problem consisting of multiple goods, heterogeneous agents, and a nonconvex policy maker optimization problem. Our approach allows for more dimensions of heterogeneity than has been previously possible,...

The overlapping generations (OLG) model is an important framework for analyzing any type of question in which age cohorts are affected differently by exogenous shocks. However, as the dimensions and degree of heterogeneity in these models increase, the computational burden imposed by rational...

This paper looks at the linkages between growth and business cycles by bringing together two strands of literature. We incorporate a quality ladders engine of growth into an otherwise standard real business cycle model. Our fundamental question is, can Schumpeter’s creative destruction...

Purpose – Studies of the cyclical behavior of real wages have identified monetary shocks and examined the response of real wages and output or employment. A finding that real wages are procyclical in response to a positive monetary policy shock is taken as evidence that prices are stickier...

This paper contains a dynamic general equilibrium model with an endogenous process for growth and business cycles driven partly by technological discovery and diffusion. The model integrates two branches of the literature. One is literature on Schumpeterian, or "quality ladder," models, in which...

We present a discrete-time version of an otherwise standard Schumpeterian growth model. Discrete time exhibits two important differences from continuous time. First, the probability of successful innovation cannot be homogeneous of degree one in inputs. A natural R&D analogue to constant returns...
