Potentially dynamically-inconsistent individuals create particular problems for economics, as their behaviour depends upon whether and how they attempt to resolve their potential inconsistency. This paper reports on the results of a new experiment designed to help us distinguish between the...

We study a model in which risk-averse consumers obtain mutual insurance by participating voluntarily in pools. More precisely, consumers commit to contributing a fraction of their future uncertain endowment to a common pool. In exchange, they gain the right to receive a share of the total return...

In this paper, we study a two-period pure exchange economy with idiosyncratic uncertainty, moral hazard and multiple consumption goods. We consider two different market structures: contingent commodity markets on the one hand, and financial plus spot commodity markets on the other hand. We...

We define a standard optimization problem with quadratic objective function and provide a rigorous visual proof for its solution without using calculus. We then show that such standard problem is a building block for several economic models related to microeconomics, game theory and pricing...

In this note, I study how the magnitude of the substitution and the income effects affects the change in the demand for a good following an own-price variation in a single consumer choice model with multiple goods.

We extend the framework of Dubey and Geanakoplos (2002) to the case of moral hazard. We analyze the equilibrium properties of the model and we show that equal ex-ante consumers may choose to promise differently, and, as a consequence, choose different actions. This illustrates how the pool of...
