We provide two new indices of efficiency for determining the degree of coherence in an agent's consumption decisions. We analyze to which extent they improve the efficiency displayed by Varian's (Journal of Econometrics, 1990) index. We report on the results of a Montecarlo experiment that...

Consider an experiment in which subjects are asked to choose between pairs consisting of a monetary payment and a time-delay at which the payment is delivered. Given a finite set of observations, under what conditions the choices of an individual agent can be rationalised by a discounted utility...

In this paper we conduct two proper tests of overconfidence. We reject the hypothesis "the data cannot be generated by a rational model" in both experiments.

The model presented here derives the product life cycle of durable goods. It is based on the idea that the purchase process consists of first purchase and repurchase. First purchase is determined by the market penetration process (diffusion process), while repurchase is the sum of replacement...

Changing household behaviour is often encouraged as a means of reducing energy demand and subsequently greenhouse gas (GHG) emissions. The direct and indirect rebound effects from cost-saving ‘green’ household consumption choices were estimated using Australian data. Rebound effects from...

This study sheds new light on the question of whether or not sentiment surveys, and the expectations derived from them, are relevant to forecasting economic growth and stock returns, and whether they contain information that is orthogonal to macroeconomic and financial data. I examine 16...

The aim of this paper is to overcome the problems caused by insufficient price variation in estimating a large demand system. For that, we propose a new form of Stone-Lewbel (SL) cross section prices developed under latent separability that explore individual specific variation in the...

The main research question of this paper is whether or not the risk of family disruption has an impact on the consumption/saving decisions of households. Although little empirical work exists in this area, often presenting indirect evidence, the theory is divided over the effect of family risk...

This paper uses 2973 loan profile records of 2810 poor households who have taken these loans from different quasi-formal sources of which about 50 percent of the loan taken is supplied by the Ultra-poor oriented program designed by PKSF. The objective of this program was to create some income...
