We present a continuum economy with risk neutral agents having heterogeneous expectations and restricted short sales. A stochastic version of the model is also formulated and the resulting time series behavior of the price and volume series under a specific money supply process derived. The implications of the model are tested in the emerging Turkish stock market where institutional arrangements comply with the restrictions of the model. The results indicate that, as predicted by the model, price levels and trading volume are cointegrated. The error correction models are also estimated and found to be significant in most cases

Cataloged from PDF version of article.This paper introduces a learning algorithm that allows for imitation in recursive dynamic games. The Kiyotaki-Wright model of money is a well-known example of such decision environments. In this context, learning by experience has been studied before. Here, we introduce imitation as an additional channel for learning. In numerical simulations, we observe that the presence of imitation either speeds up social convergence to the theoretical Markov-Nash equilibrium or leads every agent of the same type to the same mode of suboptimal behavior. We observe an increase in the probability of convergence to equilibrium, as the incentives for optimal play become more pronounced

This paper studies money as working capital in a general equilibrium model. We argue that the way transactions are settled is the main determinant of the presence or lack of working capital in a cash-in-advance economy. In a production cycle, if the wage payments are made before sales proceeds are collected, firms have a financing need. This need alone brings, in a long run equilibrium, adeviation of real wages from marginal product of labor due to a 'working capital premium' in output prices. In contrast, if sales revenues can be collected before production costs are paid, then the working capital premium vanishes. These results are obtained in an economy with borrowing constraints, full equity financing, and optimal dividend policy.
