The objective of this manuscript is to provide a simple guide to instructors and students on how to solve and simulate a discrete-time specification of the Life-Cycle/Permanent-Income Model of Consumption and Saving (LCPI Model) using only algebra and basic calculus. The solution and simulation...

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...

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...

In this paper we document significantly steeper declines in nondurable expenditures in the UK compared to the US, in spite of income paths being similar. We explore several possible causes, including different employment paths, housing ownership and expenses, levels and paths of health status,...

Children are seldom accounted for in household behavioural models. They are usually assumed to have neither the capacity nor the power to influence the household decision process. The literature on collective models has so far incorporated children through the "caring preferences" of their...

Various deviations from the Permanent Income consumption model with rational expectations have been discussed in the literature, including loss aversion and liquidity constraints. In the existing literature, these two types of consumption asymmetry are usually considered as mutually exclusive....

We propose a new methodology to estimate the share of household income accruing to children (i.e., the cost of children). Following the principle of the Rothbarth approach, the identification of the children's share requires the observation of at least one adult-specific good. However, our...

We apply an extension of the Rothbarth approach to estimate the share of household resources accruing to children (i.e., the cost of children) in Ireland. The method also allows us to identify the economies of scale in the household and indifference scales in Lewbel (2003)’s sense. A practical...

Contrary to the popular notion that money that is easily earned, is also easily spent, economic theory holds that income is fungible. Drawing on the concept of mental accounting, this study theoretically explores when such a link between spending behaviour and the effort dispensed in obtaining...

This paper deals with different concepts of income elasticities of demand for a heterogenous population and the relationship between individual and aggregate elasticities is analyzed. In general, the aggregate elasticity is not equal to the mean of individual elasticities. The difference depends...
