Several authors have implemented computer code automating the application of perturbation methods for constructing solutions for dynamic economic models.\cite{sims01,chen99,collard,schmitt,judd98,anderson02} Such techniques facilitate the construction and use of nonlinear stochastic models for...

In an American continuous-installment option the premium, instead of being paid up-front, is paid at a certain rate per unit time. At any time at or before maturity date, the holder has the right to terminate payments and either exercise the option or "walk away" from deal. Under the standard...

The paper studies empirically and analytically growth and fluctuation of firm size distribution. An empirical analysis is carried out on several data sets on firm size, with emphasis on one-time distribution as well as growth-rate probability distribution. Two well-known scaling laws, Pareto's...

In this paper we solve a stochastic dynamic programming problem for the solution to a dynamic game in which the players select a mean level of control. The state transition dynamics are a function of the current state of the system and a multiplicative noise factor on the control variables of...

Simulations have become a common tool to study the implications of theoretical models. In addition, computational approaches are frequently used in statistics to adapt models to reality. We aim to merge these approaches. To obtain robust results with significant validity from simulations,...

The purpose of this paper is to examine the optimality of the monetary authorities reaction function in the two-area medium size model MARCOS (US and euro areas). The parameters and the horizons of output gap and inflation expectations of the Taylor rule are computed in order to minimise a loss...

The paper describes and illustrates a method for generalizing the standard computation of period-to-period percentage change of total factor productivity (TFP) to computation of TFP based on a best k-times-differentiable model. A "model" is a k-times-differentiable functional form of a...

The Circuitists are a largely European school of economic thought that argue that a monetary economy is fundamentally different to a barter system, and that therefore money cannot be simply modelled as the n+1th good in a Walrasian general equilibrium system. However, while the School has made...

Our concern in this paper is that the capability of economics undergraduates is substantially underestimated in the design of the present college curriculum and that our students are insufficiently challenged and motivated. Students enter our classrooms with substantial previous knowledge about...

Differential equations with advanced and delayed time arguments may arise in the optimality conditions of simple growth models with delays. Models with investment gestation lags (time-to-build), consumption gestation lags (habit formation) or learning by using lie in this category. In this...
