This paper develops an endogenous growth model of occupational choice with overlapping generations heterogeneous in entrepreneurial ability. While an increase in the number of entrepreneurs creates a growth-enhancing variety effect, the reduced overall quality of entrepreneurial ability retards...

This paper studies the implications for optimal monetary policy of introducing job search into the new Keynesian framework. Using the linear-quadratic approach described by Benigno and Woodford (2008), we derive a utility-based loss function that indicates that the goals of policymakers can be...

Asset price bubbles can arise unintentionally when one uses continuous-time diffusion processes to model financial quantities. We propose a flexible damped diffusion framework that is able to break many types of bubbles and preserve the martingale pricing approach. Damping can be done on either...

Several authors have questioned the evidence claimed by Galí and Gertler (1999) and Galí et al. (2001) that a hybrid version of the new Keynesian Phillips curve approximates European and US inflation dynamics quite well. We re-examine the evidence using the vector autoregressive framework and...

Several theoretical contributions using two-country models have combined alternative forms of pricing under nominal rigidities with different asset market structures to explain real exchange rate dynamics. We estimate a two-country model using data for the United States and the Euro Area, and...

Models of the monetary transmission mechanism often generate empirically implausible business fluctuations. This paper analyzes the role of on-the-job search in the propagation of monetary shocks in a sticky price model with labor market search frictions. Such frictions induce long-term...

The paper is concerned with the hedging of credit derivatives, in particular synthetic CDO tranches, in a dynamic portfolio credit risk model with spread risk and default contagion. The model is constructed and studied via Markov-chain techniques. We discuss the immunization of a CDO tranche...

The motivation of this paper is to understand the effects of coupling a macroeconomic model of inflation rate dynamics, relying on an aggregate expectation, to a heterogeneous expectations framework. A standard model composed of Okun's law, an expectations-augmented Phillips curve and an...

This paper analyzes the Markov-perfect equilibrium of an economy were a benevolent government that lacks the ability to commit to future policy choices, uses taxes on capital and labor income to finance the provision of a public good. The main finding is that the government taxes capital and...

Using a variation of the coupling from the past technique, this paper develops algorithms which generate independent observations from the stationary distributions of various dynamic economic models. These variates can be used for calibration, calculation of steady state phenomena, and...
