This paper characterizes the stationary equilibrium of a continuous-time neoclassical production economy with capital accumulation in which households can insure against idiosyncratic income risk through long-term insurance contracts. Insurance companies operating in perfectly competitive...

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...

I document a statistical link between old-age dependency ratios and average markups. I propose that a mechanism whereby households develop deep habits in consumption as they age could explain this feature of the data. I show that when this mechanism is embedded in an overlapping generations New...

This paper provides an introduction to the field of evolutionary economics with emphasis on the evolutionary theory of household behavior. It shows that the goal of evolutionary economics is to improve upon neoclassical economics by incorporating more realistic and empirically grounded...

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...

US data and new stockholding data from fifteen European countries and China exhibit a common pattern: stockholding shares increase in household income and wealth. Yet, there is a multitude of numbers to match through models. Using a single utility function across households (parsimony), we...

The purpose of this study is to explore the effects of exogenous social security system parameters on welfare. The set up is an overlapping generations economy, with skills heterogeneity, which distinguishes consumers between high and low skilled. The lowskilled receive an extra supplement...

We analytically show that a common across rich/poor individuals Stone-Geary utility function with subsistence consumption in the context of a simple two-asset portfolio-choice model is capable of qualitatively and quantitatively explaining: (i) the higher saving rates of the rich, (ii) the...
