The aim of this paper is to propose an analytical framework, wherein the individuals' choice problem is addressed in terms of alternative time‐consuming activities rather than in terms of alternative bundles of goods and services. In particular, the paper reverses Becker's (1965) proposal to...

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...

The paper presents an extended version of the consumer choice problem. Different from the standard model, prices are not fixed but arise from Walrasian interactions of total demand and a stylized supply function for each of the goods. Three different types of evolutionary algorithms are set up...

Risk may induce precautionary saving but it can also reduce saving. The theoretical literature recognizes both possibilities, but favors a positive effect (both for developed and developing countries); the empirical literature is divided, reporting (small) positive effects for developed...

Many budget surveys present the interesting features that for a wide range of goods they contain quantity information along with expenditure information, and that the geographical location of households is fairly precise. We take advantage of these features to develop a method for estimation of...

The vast majority of household wealth in the U.S. is held in illiquid assets, primarily housing, making households vulnerable to unexpected income shocks. To rationalize this preference for illiquidity, we build a life-cycle model where households are tempted to consume their liquid wealth but...

How are substitution in the spatial and in the temporal sense connected? Can estimates based on data with spatial variation be transmitted into values appropriate for exploring temporal variation, and vice versa? This paper, building on, inter alia, Frisch (1959), attempts to give some...

Most simulated micro-founded macro models use solely consumer-demand aggregates in order to estimate deep economy-wide preference parameters, which are useful for policy evaluation. The underlying demand-aggregation properties that this approach requires, should be easy to empirically disprove:...

Consumption theory has always been a neglected field in Post Keynesian economics, whereas it is at the center of New Keynesian economics. This paper investigates similarities and differences between the two approaches. I will show that the newer mainstream models indeed give results that are...

We analyse how money as a store of value affects the decisions of a representative household under diversifiable and non-diversifiable risks. given that the central bank successfully stabilizes the rate of inflation at a low level. Assuming exponential utility allows us to derive an explicit...
