We analyze income tax evasion dynamics in a standard model of statistical mechanics, the Ising model of ferromagnetism. However, in contrast to previous research, we use an inhomogeneous multi-dimensional Ising model where the local degrees of freedom (agents) are subject to a specific social...

We review existing estimates of the size of the Spanish underground economy, apply the Ahumada et al. (2007, RIW) correction procedure to some of them and calculate the size of the underground economy in Spain for the period 1960 through 2009 by using the modified-cash-deposits-ratio (MCDR)...

In this paper I examine the influence which a population of different behavioral types may have on the provision of public goods. In particular, the population or subject pool consists of three behavioral types: myopic selfish agents, enlightened selfish agents and ethically motivated agents. I...

We derive a generalized method for calculating the total number of Paretooptimal allocations (NOPA) in typical linear public goods games. Among other things, the method allows researchers to develop new experimental designs for testing the relevance of Pareto-optimality in experimental settings,...

Based on the Ahumada et al. (2007, Review of Income and Wealth) critique we revise existing estimates of the size of the German underground economy. Among other things, it turns out that most of these estimates are untenable and that the tax pressure induced size of the German underground...

In this paper I examine the relationship between Pareto-optimality and group size in linear public goods games or experiments. In particular, I use the standard setting of homogeneous linear public goods experiments and apply a recently developed tool to identify all Pareto-optimal allocations...

We analyze the evolution and extent of income tax evasion under alternative governmental policies in an agent-based model with heterogeneous agents. A novel aspect of our modeling is the use of an exponential utility function, which allows us to assume rather realistic audit probabilities and to...

We further refine the Modified-Cash-Deposits-Ratio (MCDR) approach, developed by Pickhardt and Sardà (2011, 2012) with a view to analyze size and causes of the cash using section of the underground economy. Among other things, we address the issue of cash hoarding. Findings include that the...

In this paper, we attempt to show why the importance of relational goods compared to conventional goods and status goods threatens to decline in contemporary societies. In our point of view, the development of the relative significance of these three types of goods is not a consequence of...

In this paper, a formalization of Martin Seligman's concept of full life is presented by employing basic microeconomics. With the formalized version of the concept, it can be explained why people differ with respect to the levels of pleasant, engaged and meaningful life they are trying to...
