Relationship management is becoming more important, also in direct marketing. Measuring the strength of relationships is relevant, since relationship strength can be used as a segmentation variable. However, in measuring relationship strength, mostly one or more behavioral indicators are used...

In a single framework, I address the question of the informational basis for evaluating social states. I particularly focus on information about individual welfare, individual preferences and individual (moral) judgments, but the model is also open to any other informational input deemed...

The literature on the computation of Nash equilibria in n-person games is dominated by simplicial methods. This paper is the first to introduce a globally convergent algorithm that fully exploits the differentiability present in the problem. It presents an everywhere differentiable homotopy to...

I consider n-person normal form games where the strategy set of every player is a non-empty compact convex subset of Euclidean space, and the payoff function of player i is continuous and concave in player i''s own strategies. No further restrictions (such as multilinearity of the payoff...

The purpose of this paper is to review and discuss the key improvements brought to OxGauss. Without having to install Gauss on his or her machine, the OxGauss user can run under Ox a wide range of Gauss programs and codes. Even with the console Ox version (free for academics), Gauss codes can...

This note represents results about the extent of teaching the history of economic thought at German language based universities. At the time when cuts need to be made, many universi ties are thought of cutting non-essential courses first, of which the history of economic thought might be...

We show that, with benevolent policymakers and fiscal leadership, monetary unification reduces inflation, taxes and public spending. These disciplining effects of a monetary union, which rise with the number of fiscal players in the union, are likely to raise welfare. Joining an optimally...

The judicious use of natural resources is a crucial prerequisite for sustainable growth not only in developed countries, but even more so in the Third World. To a substantial degree, natural resource use is determined by the tax structure governing a country''s economic activity. When a tax...

In this essay, I have tried to show that the European Union inititiatives towards science and technology, ostensibly in the interest of promoting employment and growth through technological advancement, have side effects that undermine the very purpose at which they aim. The funding formula and...

Combinatorial optimization problems arise in several areas ranging from management to mathematics and graph theory. Most combinatorial optimization problems are computationally hard due to the restriction that a subset of the variables have to take integral values. During the last two decades...
