I consider an economy, populated by case-based decision makers with one-period memory. Consumption can be transferred between the periods by the means of a riskless storage technology or a risky asset with iid dividend payments. I analyze the dynamics of asset holdings and asset prices. Whereas...

We analyze a market populated by expected utility maximizers and smooth ambiguity-averse consumers. We study conditions under which ambiguity-averse consumers survive and affect prices in the limit. If ambiguity vanishes with time or if the economy exhibits no aggregate risk, ambiguity-averse...

We consider an economy, in which the elite controls the means of production. The private incentives of each elite member contradict the interests of the elite as a whole. While each member of the elite would benefit from engaging into new productive activities, the byproduct of such activities...

We present an axiomatic model of preferences over menus that is motivated by three assumptions. First, the decision maker is uncertain ex ante (i.e. at the time of choosing a menu) about her ex post (i.e. at the time of choosing an option within her chosen menu) preferences over options, and she...

The paper studies the connection between the form of the similarity function of a decision-maker and his willingness to diversify. It is shown that preference for diversification obtain for both high and low aspiration levels if the similarity function is convex in the Euclidean distance....

We build a dynamic political economy model with a two-class society, workers and the elite, in which the elite formation, the innovation rate and fiscal policy are endogenous. The model generates a mapping between institutions and patterns of growth consistent with empirical evidence. Ex ante,...
