چکیده انگلیسی
If the savings propensity for the equations is chosen according to some random distribution, we show further that the wealth distribution for large values of wealth displays a Pareto-like power-law tail, i.e., P(w)â¼w1+a. However, the value of a for the model is exactly 1. Exact numerical simulations for the model illustrate how, as the savings distribution function narrows to zero, the wealth distribution changes from a Pareto form to an exponential function. Intermediate regions of wealth may be approximately described by a power law with a>1. However, the value never reaches values of â¼1.6-1.7 that characterise empirical wealth data. This conclusion is not changed if three-body agent exchange processes are allowed. We conclude that other mechanisms are required if the model is to agree with empirical wealth data.
