This paper treats the risk-averse optimal portfolio problem with consumption in continuous time for a stochastic-jump-volatility, jump-diffusion (SJVJD) model of the underlying risky asset and the volatility. The new developments are the use of the SJVJD model with...

This paper revisits the Kareken-Wallace model of exchange rate formation in a two-country overlapping generations world. Following the seminal paper by Arifovic (Journal of Political Economy, 104, 1996, 510-541) we investigate a dynamic version of the model in which agents' decision rules are...

Human beliefs, while always remaining in equilibrium, serve as a an equilibrium selector and determine the degree of aggregate volatility. Fully rational and risk averse economic agents expect macro-level dynamics to be characterized by a specific degree of volatility. Given this expectation the...

This paper explores how speculators can destabilize financial markets by amplifying negative shocks. During periods of turmoil created by an uncertainty shock, speculators react to declining asset prices by liquidating their holdings in hopes of buying them back later at a gain, despite the...

I consider a consumption based asset pricing model where the consumer does not know if shocks to dividends are stationary (temporary) or non-stationary (permanent). The agent uses a Bayesian learning algorithm with a bias towards recent observations to assign probability to each process. While...

Using monthly data for four selected emerging economies, sterilised central bank foreign exchange intervention is found to have little systematic influence on the near-term nominal exchange rate expectations in the direction intended by the central banks. In other words, central bank dollar...

In this paper we examine the optimal level of central bank activism in a standard model of monetary policy with uncertainty, learning and strategic interactions. We calibrate the model using G7 data and find that the presence of strategic interactions between the central bank and private agents...
