Pension systems fight myopia and reduce old-age poverty. Our simple model introduces heterogeneous wages, flexible labor supply, progressive personal income tax and pension credit. The socially optimal transfer system is close to the means-tested one proposed by Feldstein (1987).

The paper shows how a dynamic neoclassical AS-AD can be derived and used to describe business cycles and growth trends to undergraduates. Derived within the Ramsey-Cass-Koopmans (RCK) model, the AS-AD is the stationary equilibrium of the deterministic dynamic general equilibrium framework....

We study coalitional games where the coalitional payoffs depend on the entire coalition structure. We introduce a noncooperative, sequential coalition formation model and show that the set of equilibrium outcomes coincides with the recursive core, a generalisation of the core to such games. In...

The paper presents a human-capital-based endogenous growth, cash- in-advance economy with endogenous velocity where exchange credit is produced in a decentralized banking sector, and money is supplied stochastically by the central bank. From this it derives an exact functional form for a general...

We introduce a new class of cooperative games where the worth of a coalition depends on the behavior of other players and on the state of nature as well. we allow for coalitions to form both before and after the resolution of uncertainty, hence agreements must be stable against both types of...

In this paper shortest path games are considered. The transportation of a good in a network has costs and benefit too. The problem is to divide the profit of the transportation among the players. Fragnelli et al (2000) introduce the class of shortest path games, which coincides with the class of...

This paper demonstrates that despite substantial transformation towards a market economy, occasions for increased state intervention will mobilize the characteristics of redistribution in party-state systems. Such state intervention occurred through the introduction of the stimulus package in...

The stable roommates problem with payments has as input a graph G(E,V) with an edge weighting w:E_ùR+ and the problem is to find a stable solution. A solution is a matching M with a vector p.RV that satisfies pu+pv=w(uv) for all uv.M and pu=0 for all u unmatched in M. A solution is stable if it...

In Hungary, the previously non-existing venture capital and private equity industry has strengthened over the past two decades, and it has become one of the leaders of the CEE region. Approximately 90% of the capital allocated to investments overall were raised from private sector investors. The...

We use data on exchange rates and consumer price indices and the weighting matrix derived by Bayoumi, Lee and Jaewoo (2006) to calculate consumer price index-based REER. The main novelties of our database are that (1) it includes data for 178 countries -many more than in any other publicly...
