This paper introduces consumption externalities into a Ramsey-type model with endogenous labour supply and homogeneous agents. The instantaneous utility of any consumer is assumed to depend on work effort, own consumption and relative consumption, where the latter determines the individual's...

Collective consumption decisions taken by the members of a household may prove inefficient. The impact of such inefficient household decisions on market performance is investigated. At one extreme, market efficiency can occur even when household decisions are inefficient, namely when household...

In our modified version of the small open economy Ramsey model, we assume that agents have preferences over consumption and status which, in turn, is determined by relative wealth. This extension potentially eliminates the standard model's counterfactual result that an impatient country over...

This paper explores whether habit formation in the representative agent’s preferences can explain two failures of the standard permanent income model with intertemporally separable utility: the sensitivity of consumption to lagged consumer sentiment and to predictable changes in current income...

The standard approach to modelling consumption/saving problems is to assume that the decisionmaker is solving a dynamic stochastic optimization problem However under realistic descriptions of utility and uncertainty the optimal consumption/saving decision is so difficult that only recently...

International and national investors are often exposed to real wealth risks, stemming from volatile asset prices and inflation uncertainty, making it difficult to stabilize consumption patterns. However, investors can enter futures markets to hedge against these risks. The paper develops a...

The aim of this paper is threefold: we first discuss the appropriateness of the traditional trust-game-tree for the analysis of trust relationships. Following the definition put forward by Lee et al. (2005) that confident expectations and a willingness to be vulnerable are critical components of...

We analyze the role of consumer expectations in a Hotelling model of price competition when products exhibit network effects. Expectations can be strong (stubborn), weak (price-sensitive) or partially stubborn (a mix of weak and strong). As a rule, the price-sensitivity of demand declines when...
