Discriminatory Price Auctions in Electricity Markets: Low Volatility at the Expense of High Price Levels

A pay-as-offered or discriminatory price auction (DPA) has been proposed to solve the problem of inflated and volatile wholesale electricity prices. Using the experimental method we compare the DPA with a uniform price auction (UPA), strictly controlling for unilateral market power. We find that a DPA indeed substantially reduces price volatility. However, in a no market power design, prices in a DPA converge to the high prices of a uniform price auction with structural market power. That is, the DPA in a no market power environment is as anti-competitive as a UPA with structurally introduced market power.     

Voluntary Contributions to a Mutual Insurance Pool

We study mutual‐aid games in which individuals choose to contribute to an informal mutual insurance pool. Individual coverage is determined by the aggregate level of contributions and a sharing rule. We analyze theoretically and experimentally the (ex ante) efficiency of equal and contribution‐based coverage. The equal coverage mechanism leads to a unique no‐insurance equilibrium while contribution‐based coverage develops multiple equilibria and improves efficiency. Experimentally, the latter treatment reduces the amount of transfers from high contributors to low contributors and generates a “dual interior equilibrium.” That dual equilibrium is consistent with the co‐existence of different prior norms which correspond to notable equilibria derived in the theory. This results in asymmetric outcomes with a majority of high contributors less than fully reimbursing the global losses and a significant minority of low contributors less than fully defecting. Such behavioral heterogeneity may be attributed to risk attitudes (risk tolerance vs risk aversion) which is natural in a risky context.     

The demand for paper and paperboard: econometric models for the European Union

Cost minimization theory suggests national demand equations for paper and paperboard in which demand is a negative function of the price of paper and paperboard, and a positive function of gross national product. A dynamic version of this model was estimated with data from European Union countries, for newsprint, printing and writing paper, and other paper and paperboard. Country-by-country equations proved unstable. Pooling the data across countries, with dummy variables to account for fixed country effects, led to well defined short-term and long-term elasticities with respect to price and gross national product. The hypothesis that income and price elasticities were the same across the European Union countries could not be rejected at the 1% significance level, for the three product groups. From 1969 to 1995, most of the growth in demand had been due to the growth in national product, while price increases had only a small negative effect.     

Discount rates and credit markets: Theory and evidence from rural india

Three models of credit markets - (1) the permanent income model, (2) upward sloping credit supply to individual borrowers, and (3) constrained credit due to imperfect enforcement - are tested using credit market data and an experimental study of individuals' discount rates in south India. The permanent income model is rejected by both the discount rate and the credit market data. The discount rate data are consistent with either of the other two models, while the credit market data are consistent with a combination of these two models. Other explanations are found to be insufficient to explain the results of this study.     

Perception of marital roles in purchase decision processes: A cross-cultural study

Following the approach of the classic 1974 marital-role influence study of Davis and Rigaux, the present study focuses on differences in decision making (i.e., joint, husband dominated, wife dominated) across 24 product categories as a function of two key factors. These factors are stage of the decision process (i.e., problem recognition, information search, and the final decision) and culture (People’s Republic of China and the United States). The Jacobson Marital-Role Egalitarianism Scale is included to further assess individual differences in husband and wife traditionality-modernism. The major findings are that emphasis on joint, husband-dominated, and wife-dominated decisions vary by stage and by stage-culture interaction.
