We construct an agent-based New Keynesian DSGE model with different social network structures to investigate the significance of network topologies to macroeconomic stability. According to our simulation results, we find that the more liquid the information flow, the higher the stability of the...

In this paper, the authors continue the pursuit of the self-coordination mechanism as studied in the El Farol Bar problem. However, in addition to efficiency (the optimal use of the public facility), they are also interested in the distribution of the public resources among all agents. Hence,...

Migration contributes to the circulation of goods, knowledge, and ideas. Using community and individual-level data from Moldova, we show that the Emigration episode that started in the late 1990s strongly affected political preferences and electoral outcomes in Moldova during the following...

It is argued that the German system of supporting low wage income earners by government transfers gives incentives for employers and employees to contract low wages and then to exploit the government. The paper analyses if such incentives do exist. It turns out that this is the case under...

This paper addresses the reduction of market failure under imperfect competition. It proposes a taxscheme that provides firms with an incentive to forgo their market power: Firms optimize after-tax profits. Now simply consider a firm´s gross profit margin the unique tax-rate it is charged on...

The paper discusses the applicability of optimal taxation theory to source-based capital incomes when significant tax evasion is observed. Without tax evasion a modified Ramsey Rule may reduce distortions brought by international capital mobility, leading to levying differentiated tax rates in...

Estimations of the shadow economies for 145 countries, including developing, transition and highly developed OECD economies over 1999 to 2003 are presented. The average size of the shadow economy (as a percent of "official" GDP) in 2002/03 in 96 developing countries is 38.7%, in 28 transition...

In many countries, fiscal policy became strongly expansionary in order to fight the recession. Structural budget deficits increased sharply and might remain high after the end of the recession. This would raise real interest rates and would impair economic growth. Some measures to reduce the...

We investigate the effects of a Financial Transaction Tax (FTT) in an order-driven artificial financial market. FTTs are meant to limit short-term speculative behavior by reducing the amount of excess liquidity in the system. To quantify these effects, adjustments in trading strategies and their...

In this paper, we develop an agent-based multi-layered interbank network model based on a sample of large EU banks. The model allows for taking a more holistic approach to interbank contagion than is standard in the literature. A key finding of the paper is that there are non-negligible...
