We present a model of price leadership on homogeneous product markets where the price leader is selected endogenously. The price leader sets and guarantees a sales price to which followers can adjust according to their individual supply functions. The price leader then clears the market by...

Like Feinberg and Sherman (1985) and Phillips and Mason (1992) we test experimentally whether conglomerate firms, i.e., firms competing on multiple structurally unrelated markets, can effectively limit competition. Our more general analysis assumes differentiated rather than homogeneous products...

We analyze how transparency affects information acquisition in a bargaining context, where proposers may chose to purchase information about the unknown outside option of their bargaining partner. Although information acquisition is excessive in all our scenarios we find that the bargaining...

We consider an economy composed of two regions. Each of them provides a public good whose benefits reach beyond local boundaries. In case of decentralization, taxes collected by members of a region are spent only on that region's public good. In case of centralization, tax receipts from the two...

A procurement contract is granted by a bureaucrat (the auctioneer) who is interested in a low price and a bribe from the provider. The optimal bids and bribes are derived based on an iid private cost assumption. In the experiment, bribes are negatively framed (betweensubjects treatment) to...

Problems of social coordination can be formalized as non-cooperative games with several equilibria. We know that in such situations serious problems of equilibrium selection arise which cannot be solved by traditional game theoretical reasoning. Conventions seem to be a powerful tool to solve...

The phenomenon of predating predators requires at least three specimens to whom we refer as players 1, 2, and 3. Player 1 has simply to guess nature when trying to find food. Player 2 is hunting player 1 in the hope that 1 is well fed but must also avoid being hunted by player 3. One major...

In this paper we report experimental results that relate to the recprocity experiment of Berg, Dickhaut, and McCabe (1995). We consider direct reciprocity, which means to respond in kind to another person, and indirect reciprocity, understoode as rewarding someone else. Another variation conerns...

Experimental studies have shown that trust and reciprocity are effective in increasing efficiency when complete contracting is infeasible. One example is the study by Berg et al. (1995) of the investment game. In this game the person who receives the investment is the one who may reward the...
