In this article we address the problem of finding feedback Nash equilibria for linear quadratic differential games defined on descriptor systems. First, we decouple the dynamic and algebraic parts of a descriptor system using canonical projectors. We discuss the effects of feedback on the...

In this note we generalize a numerical algorithm presented in [9] to calculate all solutions of the scalar algebraic Riccati equations that play an important role in finding feedback Nash equilibria of the scalar N-player linear affine-quadratic differential game. The algorithm is based on...

In this paper we consider the discounted linear quadratic differential game for descriptor systems that have an index larger than one. We derive both necessary and sufficient conditions for existence of an open-loop Nash (OLN) equilibrium. In a small macro-economic stabilization game we...

In this article we analyze how the presence of thresholds influences multi agent decision making situations. We introduce a class of discounted autonomous optimal control problems with threshold effects and discuss tools to analyze these problems. Later, using these results we investigate two...

In this note we consider the non-cooperative linear feedback Nash quadratic differential game with an infinite planning horizon for descriptor systems of index one. The performance function is assumed to be indefinite. We derive both necessary and sufficient conditions under which this game has...

In this note we consider the non-cooperative linear feedback Nash quadratic differential game with an infinite planning horizon. The performance function is assumed to be indefinite and the underlying system affine. We derive both necessary and sufficient conditions under which this game has a...

We construct a theoretical model of labor markets with human capital accumulation to understand and quantify the earnings losses for young workers generated by unemployment: unemployment represents time forgone in terms of human capital accumulation, which adversely affects long-term income...

We study the entry into legitimate employment and earnings of a large sample of convicts released from Hungarian prisons in 2002-08. The employment rate of the prisoners falls short of 20% one year before incarceration, and they earn 25% below the national average. We identify the effect of...

Since the beginning of the financial crisis in 2008, the Dutch economy lost 6% of gdp relative to Germany, even though the Netherlands (unlike the GIPSI countries) did not face serious problems to finance its sovereign debt. This bad performance is explained by the interaction of fiscal policy...

We sketch a visionary strategy for Europe in which full employment is quickly regained by 2020, income inequality is reduced and the economies are more sustainable. We call this scenario "vibrant". It is contrasted with what would happen if present policies continue within the European Union...
