This paper presents the design and implementation of negotiation agents that negotiate with other entities for acquiring multiple resources. In our approach, agents utilize a time-dependent negotiation strategy in which the reserve price of each negotiation issue is dynamically determined by 1) the likelihood that negotiation will not be successfully completed (conflict probability), 2) the exp...

In private-value ascending auctions, the winning bidder’s willingness to pay is not observed. Under assumptions weaker than independent private values, the joint distribution of bidder valuations is not identified (see Athey and Haile (2002)), so the expected revenue at a positive reserve price, and the reserve price that would maximize expected revenue, are not uniquely pinned down. In a separ...

This paper considers a duopoly price-choice game in which the unique Nash equilibrium is the Bertrand outcome. Price competition, however, is imperfect in the sense that the market share of the high-price firm is not zero. Economic intuition suggests that price levels should be positively related to the market share of the high-price firm. Although this relationship is not predicted by standard...

Despite the resurgence of parastatal marketing boards and strategic grain reserves over the last decade in eastern and southern Africa, there is little empirical evidence about how their activities affect smallholder input use and cropping decisions. This paper uses panel survey data from 1997-2007 on Kenyan smallholders to investigate the effect of Kenya’s National Cereal Produce Board activit...

Abstract: When a firm must choose price and output before observing demand and therefore risks unsold output, the standard mark-up rule applies with the elasticity being the elasticity of the average quantity sold with respect to price and marginal cost being the marginal cost of an expected unit sold, computed as the marginal cost of a unit produced divided by the expected fraction of the marg...

The optimal harvesting policy is calculated as a function of the entering stock, the price state, the harvesting cost, and the rate of interest in the capital market. In order to determine the optimal harvest schedule, the growth function and stumpage price process are estimated for the Swedish mixed species forests. The stumpage price is assumed to follow a stochastic Markov process. A stochas...

Late maturing α-amylase (LMA) is a genetic defect in some wheat lines that when triggered by particular environmental conditions damages the grains’ starch and reduces its suitability in processing. To lessen the risk of LMA expression in Australia’s wheat crops, a testing regime is now part of the nation’s varietal classification system. This paper analyses the impact of relaxing the testing r...

Simultaneously long short (SLS) feedback trading strategies are known to yield positive expected gain by zero initial investment for price processes governed by, e.g., geometric Brownian motion or Merton’s jump diffusion model. In this paper, we generalize these results to positive prices with stochastically independent multiplicative growth and constant trend in discrete and continuous time as...
