We characterize optimal consumption policies in a recursive intertemporal utility framework with local substitution. We establish existence and uniqueness and a version of the Kuhn-Tucker theorem characterizing the optimal consumption plan. An explicit solution is provided for the case when the...

The paper reconstructs Sraffa's assessment of utility-based and individualistic explanations of demand in Marshallian economics in the light of some fresh evidence provided by Sraffa's unpublished manuscripts of the 1920s. It is shown that Sraffa criticised the standard Marshallian explanation...

Evidence suggests that consumers do not perfectly optimize, contrary to a critical assumption of classical consumer theory. We propose a model in which consumer types can vary in both their preferences and their choice behavior. Given data on demand and the distribution of prices, we identify...

We solve Ireland's (1994) conspicuous consumption model (where social-status concerns are introduced into the utility function) for Cobb-Douglas (CD) utility. In the resulting generalized CD consumer model, Engel curves are no longer limited to linearity. In the homothetic CD case, total...

In this paper we remark on the existence of a link between monetary income constraint and price elasticity of demand. This finding allows us to rewrite, and extend, the standard Engel Aggregation Condition, in terms of price elasticity, and not only with regard to income elasticity of demand

This paper studies the infinite horizon optimal consumption with a path-dependent reference under the exponential utility. The performance is measured by the difference between the non-negative consumption rate and a fraction of the historical consumption maximum. The consumption running maximum...

In the present paper an analysis of the neo-classical optimization model with linear constraints is proposed. By introducing the dual problem it is shown that the solution to the maximization problem is also a solution to the minimization problem. The purely theoretical model proposes a...

We consider the problem of optimal consumption for an investor who is risk and uncertainty avers. We model these preferences of the investor with the help of a convex risk-measure. Apart from consumption the agent has the possibility to invest initial capital and random endowment in a market...

We explore effects of simultaneous price changes for the demand of a group of goods, which we refer to as a compound commodity. Specifically, we consider unit and proportional cost components (e. g., taxes, transportation costs, etc.) imposed on the compound commodity. We find that there is a...
