We study a family of models of tax evasion, where a flat-rate tax finances only the provision of public goods, neglecting audits and wage differences. We focus on the comparison of two modeling approaches. The first is based on optimizing agents, who are endowed with social preferences, their...

The phenomenon of infrequent price changes has troubled economists for decades. Intuitively one feels that for most price-setters there exists a range of inaction, i.e. a substantial measure of the states of the world, within which they do not wish to modify prevailing prices. However, basic...

Savings behaviour seems to exhibit heterogeneity across nations, and within nations, too. Large changes in saving rates have been observed in the last decades that can be viewed as signs of the arbitrariness of saving. There is a long tradition in the savings literature that separates people...

It is well known that the size of the informal (black or grey) economy causes serious fiscal problems for Hungary. This study makes an attempt to quantify the budgetary and macroeconomic effects of different ways of widening the formal sector (whiteningʺ) with the help of a model. It turns out...

Macroeconomic modelling is a recent development within the rapidly advancing field of agentbased modelling. Like older macromodels macro ABMs must also feature a well-designed consumption-savings block. As the microeconomic ABM literature on savings is non-existent researchers had to resort to...

We set up an agent-based macromodel focusing on consumption-saving without the assumption of utility maximization, but preserving certain "rational" aspects of human choice based on the idea of ecological rationality Todd et al. (2012). In this framework we address the classical problem of the...
