This paper theoretically and experimentally explores a fixed price mechanism inwhich, if aggregate demand exceeds supply, bidders are proportionally rationed. Ifdemand is uncertain, in equilibrium bidders overstate their true demand in order toalleviate the effects of being rationed. This effect...

We present laboratory experiments of five different multi-unit auction mechanisms. Two units of a homogeneous object were auctioned off among two bidders with flat demand for two units. We test whether expected demand reduction occurs in open and sealed-bid uniform-price auctions. Revenue...

We compare sequential and bundle auctions in a framework of successive procurement situations, where current success positively affects future market opportunities and competition varies across projects. We find that - if allocation of the projects has to be ensured - bundle auctions with...

We experimentally investigate the effect of imperfect separation of groups on group selection and cooperation in a standard prisoner¿s dilemma environment. Subjects can repeatedly choose between two groups, where in one of them an institutionalized norm fosters cooperation. The degree of...

We compare sequential and bundle procurement auctions in a framework of successive procurement situations, where current success positively or negatively affects future market opportunities. We find that in bundle auctions procurement cost is lower and less risky than in sequential standard...

In liberalized electricity markets strategic firms compete in an environment characterized by fluctuating demand and non-storability of electricity. While spot market design under those conditions by now is well understood, a rigorous analysis of investment incentives is still missing. Existing...

We analyze a market game where firms choose capacities under uncertainty about future market conditions and make output choices after uncertainty has unraveled. We show existence and uniqueness of equilibrium under imperfect competition and establish that capacity choices by strategic firms are...
