This paper complements research on how {\em love of wealth} bears on key variables in a Ramsey-Cass-Koopmans growth framework. It is shown that for an optimum the social planner cannot have an excessive {\em love of wealth}. If the planner has the `right' {\em love of wealth} an optimum exists...

The study looks at primary expenditure developments in the euro area, its three largest members and four “macro-imbalances” countries for the period 1999- 2009. It compares actual expenditure trends with those that would have prevailed if countries had followed neutral policies based on...

This paper studies the influence of shared guilt and diffused responsibility in institutions that may require the support of several actors to realize specific outcomes. Decision makers weigh supporting an immoral yet egoistically advantageous action to the detriment of a third party against...

That institutions matter is widely accepted among economists and so are social norms as an important category of informal institutions. Social norms matter in many economic situations, but in particular for markets. The economic literature has studied the interrelation between markets and social...

Economists have a long tradition in identifying the evolution of cooperation in large, unstructured societies as a puzzle. We suggest a new explanation for cooperation which avoids restrictions of most previous attempts. Our explanation deals with the role of internalized norms for cooperation...

We analyze the interplay of group identity and inter-group conflict in a contest where each of two conflicting groups can develop either a group or an individualistic identity. Contest structures impact on the adoption of identities which themselves influence behavior in the contest. We show the...

This paper analyzes intertemporal effort provision in two-stage tournaments. A principal with a fixed budget for prizes faces two risk-neutral agents. He observes noisy signals of effort in both periods. His goal is to maximize either total efforts (perfect substitutes) or the product of first-...

We find new equilibria of minimum-revenue core-selecting (MRCS) auctions that, in contrast to previously identified equilibria, involve overbidding - bidding more than one's true value for some packages of goods. With full information, every MRCS auction in every possible setting has equilibria...

The EU member states have declared to strongly increase the share of Renewable Energy Sources in the next decades. Given a large deployment of wind and solar capacities as well as limited cost-efficient storage technologies, this has two major impacts on electricity systems. First, the...

I reconsider the division of the literature into models with forward-looking voters and models with backward-looking voters by developing a model that incorporates motives from both literatures. As long as there is no uncertainty about preferences and parties can commit in advance to the...
