We study the adjustment process of a small open economy to a sudden worsening of external conditions. To model the sudden stop, we use a highly non-linear specification that captures credit constraints in a convenient way. The advantage of our approach is that the effects of the shock become...

Optimal power flow (OPF) problems are focussing on the question how a power transmission network can be operated in the most economic way. The general aim in such scenarios is to optimize generator scheduling in order to meet consumption re-quirements, transmission constraints and to minimize...

Let us consider a financially constrained leveraged financial firm having some divisions which have invested into some risky assets. Using coherent measures of risk the sum of the capital requirements of the divisions is larger than the capital requirement of the firm itself, there is some...

Based on the critical assumption of strategic complementarity, this paper builds a general model to describe and solve the screening problem faced by the monopolist seller of a network good. By applying monotone comparative static tools, we demonstrate that the joint presence of asymmetric...

We analyze time-costly decision-making in committees by privately informed individuals, such as juries, panels, boards, etc. In the spirit of the Coase Conjecture, we show that the decision is "almost instantaneous" when individuals entertain identical objectives. Delay can only be understood as...

While they use the language of game theory known measures of a priory voting power are hardly more than statistical expectations assuming voters behave randomly. Focusing on normalised indices we show that rational players would behave differently from the in-dices predictions and propose a...

The paper discusses the risks and challenges faced by the new members on the road to the euro and the strategies for and timing of euro adoption. We investigate the real-nominal convergence nexus from the perspective of euro area entry. We argue that the initial level of economic development as...

In this paper we describe a theoretical model of optimal investment of various types of financially constrained firms. We show that the resulting relationship between internal funds and investment is non-monotonic. In particular, the magnitude of the cash flow sensitivity of the investment is...

Studying all possible pairs of eleven major currencies and eleven portfolios in 1976-2008 we show that, when there is no leverage, carry trade is significantly profitable for most currency pairs and portfolios. Positive returns do not diminish in time providing a strong case against the...

The structure of trade expansion in Hungary and Poland over the period 1990-1998 and its implications for labour-market adjustment is examined. An econometric analysis of trade and employment data suggests that changes in domestic consumption and productivity have significant influence on...
