Exponential-growth bias (EGB) is the tendency for individuals to partially neglect compounding of exponential growth. We develop a model wherein biased agents misperceive the intertemporal budget constraint, and derive conditions for overconsumption and dynamic inconsistency. We construct an...

We evaluate the income elasticity of the aggregate budget share spent on a sub-group of commodities, in a competitive framework, by a continuum of agents having the same income, but heterogeneous behavior described by an "homothetic preferences scaling factor" having a bounded Pareto...

In this paper we examine the link between wage inequality and consumption inequality using a life cycle model that incorporates household consumption and family labour supply decisions. We derive analytical expressions based on approximations for the dynamics of consumption, hours, and earnings...

The paper focuses on the ongoing debate on non-market valuation, including the valuation environmental goods, and the opportunity to use contingent valuation for policy guidance. In fact, contingent valuation critics argue that reported willingness to pay answers do not reflect real economic...

This paper finds declining consumption expenditure between paydays, for a typical household in the working population of the UK. The magnitude is inconsistent with exponential time preference, but compatible with quasi-hyperbolic discounting. However, the hyperbolic model predicts that credit...

This paper uses detailed diary information from the British Family Expenditure Survey (FES) to investigate the expenditure patterns of school-age children. We estimate a Quadratic Almost Ideal Demand System, and find that, whilst most commodities are normal goods, sweets and toys are luxury...

We propose a collective labor supply model with household production that generalizes an original model of Blundell, Chiappori and Meghir (2005). In our model, adults' individual preferences do not only depend on own leisure and individual private consumption of market goods. They also depend on...

This paper sets up a model of private consumption for selected EU countries with special emphasis on the consumption categories heating and transport. Sustainable consumption patterns require a "decoupling" of energy or materials use from satisfaction of consumers' needs and demands. Starting...

This paper compares predictions obtained for the analysis of tax reforms with collective and unitary models of household labour supply and consumption behaviour. We simulate real world microdata by means of a collective approach, using a compound procedure of estimation and calibration based on...

Modern macroeconomics empirically addresses economy-wide incentives behind economic actions by using insights from the way a single representative household would behave. This analytical approach requires that incentives of the poor and the rich are strictly aligned. In empirical analysis a...
