We use a distributed parallel genetic algorithm (DPGA) to nd numerical solutions to a single state deterministic optimal growth model for both the innnite and nite horizon cases. To evaluate the DPGA we consider a version of the Taylor-Uhlig problem for which we know the analytical solutions. The rst-order conditions for the innnite horizon case lead to a(More)
"The limitations of available migration data preclude a time-series approach of modeling interstate migration [in the United States]. The method presented here combines aspects of the demographic and economic approaches to forecasting migration in a manner compatible with existing data. Migration rates are modeled to change in response to changes in(More)
This paper addresses the relationship between property regimes and land degradation outcomes, in the context of peasant agriculture. We consider explicitly whether private property provides for superior soil resource conservation, as compared to common property and open access. To assess this we implement optimization algorithms on a supercomputer to(More)
There has been considerable interest recently in long memory models able to capture complex features in both the spectral density and autocorrelation functions of time series data. We present a multiple frequency Gegenbauer autoregressive moving average, or k-factor GARMA, model and we derive the asymptotic distributions for a conditional sum of squares(More)
We examine market dynamics in a discrete-time, Lucas-style asset-pricing model with heterogeneous, utility-optimizing agents. Finitely many agents trade a single asset paying a stochastic dividend, and know the probability distribution of the dividend but not the private information of other agents. The market clearing price is determined endogenously in(More)
We examine market dynamics in a discretetime, Lucas-style asset-pricing model with heterogeneous, utility-optimizing agents. Finitely many agents trade a single asset paying a stochastic dividend. All agents know the probability distribution of the dividend but not the private information such as wealth and asset holdings of other agents. The market(More)
We present a simple and fast iterative, linear algorithm for simultaneously stripping the coupon payments from and smoothing the yield curve of the term structure of interest rates. The method minimizes pricing errors, constrains initial and terminal conditions of the curves and produces maximally smooth forward rate curves.
We study a simple model based upon the Lucas framework where heterogeneous agents behave rationally in a fully intertemporal setting but do not know other investors’ personal preferences, wealth or investment portfolios. As a consequence, agents initially do not know the equilibrium asset pricing function and must make guesses which they update via adaptive(More)
