In this paper, we consider two polar dynamical models in which firms use debt (loans) to finance their investment expenditure: a three-dimensional supply-driven model and a sophisticated 20-D Keynesian growth model. In the first, firms' debt accumulations interact with the income distribution...

For years, the problems associated with the Lucas critique have loomed over empirical macroeconomics. However, relatively little effort has been devoted to testing the empirical importance of this critique. This paper develops a set of tests for small macroeconometric models, especially those...

The ancillary hypothesis of unbounded rationality has dominated economic modelling for several decades. This extreme assumption has been relaxed in a fast growing literature under different headings: new institutional economics, experimental economics (E.E.), or behavioral and evolutionary...

By design, a wavelet's strength rests in its ability simultaneously to localize a process in time-scale space. The wavelet's ability to localize a time series in time-scale space directly leads to the computational efficiency of the wavelet representation of an N x N matrix operator by allowing...

This paper describes how a decision-making system for a market-selection game can be automatically designed through the iteration of the game. Our market-selection game is a non-cooperative repeated game where many players compete with one another at several markets. At each iteration, each...

To implement continuous time option pricing models in which ARCH models can be used as direct or indirect approximators of stochastic volatility, we construct continuous time economies exhibiting equilibrium dynamics to which most asymmetric ARCH models converge in distribution as the sample...

Much has been said about the possibility that in the information age, ease of entry and global access will lead to market characteristics with few inefficiencies. While several arguments have been articulated on the nature of markets and electronic commerce, little is known about their...

This paper discusses a time-series model for daily tax revenues. The model is an unobserved-components model with trend and seasonal components that vary over time. The seasonalities for inter-month and intra-month movements are modelled using stochastic cubic splines. The model is made...

Starting from De Canio and Watkins (1996) model of the firm, we study the diffusion of an industry-specific innovation in a digraph where each node "decides" whether or not to accept the innovation. We consider two scenarios. In the first one, the innovation is generated inside some firm and...

Two lines of literature show that increased uncertainty results in decreased vigor of the control variable in the first time period. The first line uses static models, the second dynamic. Here, the dynamic line is extended from one-state, one-control models to ones with two control variables. We...
