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...

We compare the state-price density that is implied by the cross-section of options prices with the corresponding density of the underlying asset price that is derived from an equilibrium model with Markovian stochastic volatility. If the data-generating process is of the stochastic volatility...

Here we provide a new approach for investigating competitive interactions in the large. We also study emergent strategic behaviors and analyze the effects of bounded rationality and the mimicry strategy in competitive situations. We show how society gropes its way towards equilibrium in an...
