Reinforcement-Based Adaptive Learning in Asymmetric Two-Person Bargaining with Incomplete Information

The sealed bidk-double auction is a mechanism used to structure bilateral bargaining under two-sided incomplete information. This mechanism is tested in two experiments in which subjects are asked to bargain repeatedly for 50 rounds with the same partner under conditions of information disparity favoring either the buyer (Condition BA) or seller (Condition SA). Qualitatively, the observed bid and offer functions are in agreement with the Bayesian linear equilibrium solution (LES) constructed by Chatterjee and Samuelson (1983). A trader favored by the information disparity, whether buyer or seller, receives a larger share of the realized gain from trade than the other trader. Comparison with previous results reported by Daniel, Seale, and Rapoport (1998), who used randomly matched rather than fixed pairs, shows that when reputation effects are present this advantage is significantly enhanced. A reinforcement-based learning model captures the major features of the offer and bid functions, accounting for most of the variability in the round-to-round individual decisions.     

A Critical Analysis of the Accounting Industry’s Voluntary Code of Conduct

The public accounting industry’s voluntary code of conduct in the United States is the American Institute of CPA’s Code of Professional Conduct. Based on our analysis, we conclude that the accounting industry’s current code is limited in its ability to serve the public interest in three respects. Specifically, the code is input-based, requires no third-party attestation of compliance with the code, and contains no public reporting process of code compliance/noncompliance at the accounting firm level. We propose that the accounting profession should reorient its largely input-based Code of Professional Conduct to include output-based performance measurements. We also conclude that third-party attestation of compliance with the profession’s code would help to promote compliance. Finally, we maintain that the accounting industry should initiate a public reporting process at the individual accounting firm level. Such a requirement would add a degree of public accountability as to whether a firm complies or fails to comply with the industry’s voluntary code of conduct. John D.

Quality management practices and their relationship to buyer’s supplier ratings: a study in the Korean automotive industry

This research explores if quality management practices are different among suppliers whose performance is rated high, medium, or low by a common buying company and identifies which specific practices contribute to the differences. The entire population of first-tier suppliers to a Korean auto assembler was surveyed to measure use of quality management practices. Useable returns were received from 25% of the suppliers surveyed. To measure conformance quality and overall rating, suppliers were categorized into high, medium, and low performing groups based on the buying company’s data. Multivariate analysis of variance was done using general linear model (GLM-MANOVA) to explore differences in the high-, medium-, and low-performing supplier groups based on their use of quality management practices. No statistically significant differences were found when suppliers were categorized based on conformance quality. However, when categorized based on overall rating, the highest rated suppliers were found to emphasize process management and employee satisfaction to a greater degree than the lowest rated suppliers.     

Joining a Queue or Staying Out: Effects of Information Structure and Service Time on Arrival and Staying Out Decisions

We study a class of single-server queueing systems with a finite population size, FIFO queue discipline, and no balking or reneging. In contrast to the predominant assumptions of queueing theory of exogenously determined arrivals and steady state behavior, we investigate queueing systems with endogenously determined arrival times and focus on transient rather than steady state behavior. When arrival times are endogenous, the resulting interactive decision process is modeled as a non-cooperative n-person game with complete information. Assuming discrete strategy spaces, the mixed-strategy equilibrium solution for groups of n = 20 agents is computed using a Markov chain method. Using a 2 × 2 between-subject design (private vs. public information by short vs. long service time), arrival and staying out decisions are presented and compared to the equilibrium predictions. The results indicate that players generate replicable patterns of behavior that are accounted for remarkably well on the aggregate, but not individual, level by the mixed-strategy equilibrium solution unless congestion is unavoidable and information about group behavior is not provided.JEL Classification: C71, C92, D81     

The effects of imagery-evoking radio advertising strategies on affective responses

A debate in the marketing literature concerning the relative effectiveness of various imagery-evoking strategies in influencing consumer responses to advertising has been unresolved. This study examined the effects of three imagery-evoking strategies commonly used in radio advertising—sound effects, vivid verbal messages, and instructions to imagine—in influencing mental imagery, ad-evoked feelings, and attitude toward the ad. The theoretical basis for the study is an imagery model based on propositional representations theory. Consistent with the implications of the theory, of the three strategies, sound effects had the greatest impact on imagery and affective responses. Compared with sound effects, a vivid verbal message had a slightly weaker influence. Instructions to imagine, however, had a very weak impact on imagery and no significant influence on affect. Finally, the results indicated that the three strategies interacted with one another. © 1997 John Wiley & Sons, Inc.
