Qualitative properties of optimal investment strategies for a firm with quadratic costs and non-concave revenues are analysed. Organising information in a bifurcation diagram, it is found that the organising centre of the diagram is a so-called swallow-tail singularity. This implies the...

In this paper an analytical framework using robust control was developed for the one-state and one-control variable model to examine the response of the control to changes in the "free" parameter. However, in contrast to Gonzalez and Rodriguez (2003), the sign of the ``free" parameter in the...

A number of continuous models to explain the influence of some parameters (e.g. advertising) on the diffusion of an innovation have been proposed since the seminal paper by Bass (1969). Only some recent papers deal with both spatial and temporal features as, i.e., De Cesare et al. (2003). There...

In this note a one-state, one-control variable quadratic linear problem with robust control and discount factor is developed to examine the optimal response of the first-period control to changes in future model uncertainty. A change in future model uncertainty has an effect on the optimal...

This paper builds upon the work by Tucci and Kendrick (2001) in which the authors develop a quadratic form version of the robust permanent income and pricing model described in Hansen, Sargent and Tallerini (1999). Then using the parameter values given on p. 18 of the HST paper they compute the...

The attempt to match characteristics of asset pricing models such as the risk-free interest rate, equity premium and the Sharpe ratio for models with instantaneous consumption decisions in the context of stochastic growth models has not been very successful. Many recent versions of asset pricing...

A recent literature have proposed different methods to produce second-order accurate approximation to the solutions to DGSE's from a straightforward second-order approximation of the model. Among others, Judd (2002), Jin and Judd (2002) show how to compute approximation of arbitrary order on...

The research on financial engineering by means of genetic programming is gradually popular and appealing. For example, Kaboudan (1999, 2001) and Iba and Sasaki (1999), Iba and Sasaki (1999), used standard GP to evolve forecasting models. Neely, et al. (1997), Allen and Karjalainen (1999), Fyfe...

Bounded rationality is introduced into a standard growth model by assuming that households form one-period ahead least squares forecasts on production factor prices, and expect that future level of consumption and physical capital will be consistent with the balanced growth path. Under those...

The stylised facts of financial data, such as fat tails, volatility clustering, and long memory, have been successfully described within the paradigm of interacting agent hypothesis. However, a common problem that characterizes the dynamics of agent-based models is the necessary fine tuning of...
