Forward commodity markets allow more efficient risk-sharing and information aggregation, but there is little evidence that this reduces the cost of producing the commodity. We develop a measure of the extent to which forward and spot prices agree in commodity markets with transaction costs and...

We analyze how market design influences the bidding behavior in multi-unit procurement auctions where suppliers have uncertain costs and are uncertain about the availability of production units, as in wholesale electricity markets. We find that the competitiveness of market outcomes improves...

We report on the results of a field experiment in Puebla, Mexico that informed randomly-selected households facing a nonlinear price schedule about how different electricity-consuming actions might change their electricity bills. Households that received this 20-minute, in-person intervention...

Hourly plant-level wind and solar generation output and real-time price data for one year from the California ISO control area is used to estimate the vector of means and the contemporaneous covariance matrix of hourly output and revenues across all wind and solar locations in the state. Annual...

This paper argues that the market rules governing the operation of the England and Wales electricity market in combination with the structure of this market presents the two major generators National Power and PowerGen with opportunities to earn revenues substantially in excess of their costs of...

We report results from a large field experiment that with a few hours prior notice provided Danish residential consumers with dynamic price and environmental signals aimed at causing them to shift their consumption either into or away from certain hours of the day. The same marginal price signal...

This paper presents several techniques for recovering cost function estimates for electricity generation from a model of optimal bidding behavior in a competitive electricity market. Two techniques are developed based on different models of the price-setting process in a competitive electricity...

Effective competition in wholesale electricity markets is a necessary feature of a successful electricity supply industry restructuring. We examine the degree of competition in the California wholesale electricity market during the period June 1998 to September 1999 by comparing the market...

We analyse how the market design influences the bidding behavior in multi-unit auctions, such as wholesale electricity markets. It is shown that competition improves for increased market transparency and we identify circumstances where the auctioneer prefers uniform to discriminatory pricing. We...

This paper provides a prospective and retrospective quantitative assessment of the impact of a passive vertical integration between a large electricity retailer and a large electricity generator in the Australian National Electricity Market (NEM). We adapt a standard model of fixed-price forward...
