We propose a simultaneous model specification procedure for the conditional mean and conditional variance in nonparametric and semiparametric time series econometric models. An adaptive and optimal model specification test procedure is then constructed and its asymptotic properties are...

. Learning about the transmission process of monetary policy is introduced by having heterogeneous agents - i.e. the central bank …. Here following Evans and Honkapohja (2001), the learning scheme we investigate is that of least-squares learning (recursive … OLS) using the Kalman filter. We find that optimal monetary policy under learning is a policy that separates estimation …

This paper analyzes a stochastic model of evolution in normal form games. The long-run behavior of individuals in this model is investigated in the limit where mutation rates tend to zero, while the expected number of mutations, and hence population sizes, tend to infinity. It is shown that...

In this paper we experimentally investigate decentralized, organizational learning. The main objective is to understand … how learning members of an organization cope with the confounding effects of the simultaneous learning of others. We use … versions of a simple "success-or-failure" game due to Blume and Franco [2003] as our stylized model of organizational learning …

We solve in closed form the optimal consumption / portfolio choice problem for the class of isoelastic utility functions under incomplete information about the mean return of the stock price. Our approach consists in converting the original investor's problem into an equivalent program where the...

One way to interpret the current policies of many central banks is that they seek to stabilize economic activity. One possible justification for such a policy is that there is volatility in macro variables that individual agents cannot insure against. We study the simplest possible extension of...

This paper studies an internet trading mechanism similar to the one described in Peters and Severinov (2001) in a market where traders values are interdependent. It is shown that under reasonable conditions this mechanism has a perfect Bayesian equilibrium which supports allocations that...
