We analyze the problem of selling shares of a divisible good to a large number of buyers when demand is uncertain. We characterize equilibria of two popular mechanisms, a fixed price mechanism and a uniform price auction, and compare the revenues. While in the auction truthful bidding is a...

This paper describes the evolution of the daily Euro overnight interestrate (EONIA) by using several models containing the jump component such asa single regime ARCH-Poisson-Gaussian process, with either a piecewisefunction or an autoregressive conditional specification (ARJI) for the...

We analyze extensively the characteristics of the solution to an irreversibleinvestment decision when the only source of uncertainty comes from interest rates.They are assumed to be driven by the popular Cox-Ingersoll-Ross (CIR) stochasticprocess. Particular attention is paid to the impact that...

In this paper we analyze incentives to invest in capacity prior to asequence of Cournot spot markets with varying demand. We compareequilibrium investment in the absence and in presence of the possibility to tradeon forward markets. We find that the possibility to trade forwards...

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...

This paper deals with analysing and forecasting intradaily volatility in electricity spot prices. We analyse the hourly spot prices from the Argentine Electricity Market by grouping prices in three daily series (block bids). We estimate the VAR model for the conditional mean structure and...

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...

The article proposes a new algorithm for adjusting correlation matrices and for comparison with Finger's algorithm, which is used to compute Value-at-Risk in RiskMetrics for stress test scenarios. The solution proposed by the new methodology is always better than Finger's approach in the sense...

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...
