gemOLG_PureExchange_Bank: Overlapping Generations Pure Exchange Models with Bank

In GE: General Equilibrium Modeling

Overlapping Generations Pure Exchange Models with Bank

Description

Some examples of overlapping generations pure exchange models with bank. Under a pay-as-you-go system, banks may only redistribute payoffs among consumers in each period. This is, in each period a bank can get a part of payoff of age1 and pay it to age2 immediately. From the consumer's point of view, the bank converts the current period's payoff into the next period's payoff. Each consumer only transacts with the bank, and she can assume that there are no other consumers.

Usage
