Original abstract

In the field of procurement, it is commonly assumed that buyers have complete knowledge about the quality of goods at the time of purchase. However, this is often not the case in reality as there are instances where the true quality of a product is only revealed long after the transaction has been made. This presents a challenge for buyers whose evaluation and satisfaction with a purchased item is heavily dependent on its quality, which may be difficult to verify or observe. To tackle this issue, researchers have focused on procurement problems where both the buyer's payoff and social surplus are affected by the quality of the acquired item. In a recent study conducted by Kun Zhang from the School of Economics at the University of Queensland, an optimal procurement mechanism was proposed to maximize a weighted average of both parties' expected benefits. This mechanism can be implemented through an auction format that sets restrictions on sellers to submit bids within specific intervals. The research highlights how such mechanisms can improve efficiency in procurement processes by aligning incentives for both buyers and sellers. It acknowledges contributions from various experts in the field who provided guidance and feedback on the findings. The study also emphasizes the significance of procurement in diverse sectors such as healthcare, government services, and manufacturing industries. By addressing challenges related to information asymmetry in procurement transactions, this research offers valuable insights for optimizing procurement strategies and ultimately improving overall market outcomes.

Introduction

Procurement is a crucial aspect of any business or organization, as it involves the acquisition of goods and services necessary for its operations. In this process, buyers are assumed to have complete knowledge about the quality of the purchased items at the time of purchase. However, in reality, this may not always be the case as there are instances where the true quality of a product is only revealed long after the transaction has been made. This presents a challenge for buyers whose evaluation and satisfaction with a purchased item is heavily dependent on its quality, which may be difficult to verify or observe.

To address this issue, researchers have focused on procurement problems where both the buyer's payoff and social surplus are affected by the quality of the acquired item. A recent study conducted by Kun Zhang from the School of Economics at University of Queensland delves into this topic and proposes an optimal procurement mechanism that can improve efficiency in procurement processes.

The Study

It aims to provide insights into how procurement mechanisms can be designed to align incentives for both buyers and sellers, ultimately leading to improved market outcomes.

Methodology

The research employs game theory models to analyze different scenarios where information asymmetry exists between buyers and sellers. Game theory is a mathematical approach used to study decision-making strategies in situations involving multiple parties with conflicting interests.

In this study, two types of players were considered: buyers who want high-quality goods and sellers who want to maximize their profits by selling low-quality goods at high prices. The researchers then proposed an auction format that sets restrictions on sellers' bids within specific intervals based on their perceived quality levels.

Findings

Through their analysis, Zhang et al. found that an optimal procurement mechanism can be designed to maximize a weighted average of both parties' expected benefits. This mechanism involves setting a reserve price, which is the minimum price that the buyer is willing to pay for the item, and a quality threshold, which is the minimum acceptable level of quality for the buyer.

The study also found that this optimal procurement mechanism can improve efficiency by reducing information asymmetry between buyers and sellers. It aligns incentives for both parties, as sellers are motivated to submit bids within specific intervals based on their perceived quality levels, while buyers have more confidence in their purchases knowing that there are restrictions in place.

Implications

The research has significant implications for various sectors where procurement plays a crucial role. These include healthcare, government services, and manufacturing industries. In these sectors, information asymmetry can lead to suboptimal outcomes such as higher costs or lower-quality goods being acquired.

By addressing challenges related to information asymmetry in procurement transactions, this research offers valuable insights for optimizing procurement strategies and ultimately improving overall market outcomes.

Contributions from Experts

The study acknowledges contributions from various experts in the field who provided guidance and feedback on the findings. This includes economists specializing in game theory and industrial organization who helped refine the model used in the analysis.

Moreover, practitioners with experience in procurement processes also provided valuable insights into real-world scenarios where information asymmetry may occur. Their input was crucial in ensuring that the proposed mechanism is applicable and effective in practical settings.

Conclusion

In conclusion, Zhang et al.'s study sheds light on how an optimal procurement mechanism can be designed to address challenges related to information asymmetry between buyers and sellers. By aligning incentives for both parties through an auction format with restrictions on bids within specific intervals based on perceived quality levels, this mechanism improves efficiency and leads to better market outcomes.

This research highlights the significance of procurement across diverse sectors and offers valuable insights for optimizing procurement strategies. It also emphasizes the importance of considering information asymmetry in procurement transactions and how it can be effectively addressed through game theory models.

Gacha Game: When Prospect Theory Meets Optimal Pricing
Tan Gan · 2022 · Theoretical Economics · AI summary available

Abstract
I study the optimal pricing process for selling a unit good to a buyer with prospect theory preferences. In the presence of probability weighting, the buyer is dynamically inconsistent and can be either sophisticated or naive about her own inconsistency. If the buyer is naive, the uniquely optimal mechanism is to sell a ``loot box'' that delivers the good with some constant probability in each period. In contrast, if the buyer is sophisticated, the uniquely optimal mechanism introduces worst-case insurance: after successive failures in obtaining the good from all previous loot boxes, the buyer can purchase the good at full price.

From Doubt to Devotion: Trials and Learning-Based Pricing
Tan Gan, Nicholas Wu · 2023 · Theoretical Economics · AI summary available

Abstract
An informed seller designs a dynamic mechanism to sell an experience good. The seller has partial information about the product match, which affects the buyer's private consumption experience. We characterize equilibrium mechanisms of this dynamic informed principal problem. The belief gap between the informed seller and the uninformed buyer, coupled with the buyer's learning, gives rise to mechanisms that provide the skeptical buyer with limited access to the product and an option to upgrade if the buyer is swayed by a good experience. Depending on the seller's screening technology, this takes the form of free/discounted trials or tiered pricing, which are prevalent in digital markets. In c…

Covert learning and disclosure
Matteo Escudé · 2023 · Theoretical Economics · AI summary available

Abstract
I study a model of information acquisition and transmission in which the sender's ability to misreport her findings is limited. In equilibrium, the sender only influences the receiver by choosing to remain selectively ignorant, rather than by deceiving her about the discoveries. Although deception does not occur, I highlight how deception possibilities determine what information the sender chooses to acquire and transmit. I then turn to comparative statics, characterizing in which sense the sender benefits from her claims being more verifiable, showing this is akin to increasing her commitment power. Finally, I characterize sender- and receiver-optimal falsification environments.

Mechanism Design with Informational Punishment
Benjamin Balzer, Johannes Schneider · 2022 · Games and Economic Behavior, 2023, 40, pp 197-209 · Not summarized yet

Abstract
We introduce \emph{informational punishment} to the design of mechanisms that compete with an exogenous status quo mechanism: Players can send garbled public messages with some delay, and others cannot commit to ignoring them. Optimal informational punishment ensures that full participation is without loss, even if any single player can publicly enforce the status quo mechanism. Informational punishment permits using a standard revelation principle, is independent of the mechanism designer's objective, and operates exclusively off the equilibrium path. It is robust to refinements and applies in informed-principal settings. We provide conditions that make it robust to opportunistic signal des…

Designing binary social decisions
Kirneva Margarita, Núñez Matías · 2023 · Theoretical Economics · AI summary available

Abstract
We design a mechanism, Majority voting with random checks, that fully implements the majority rule for binary social decisions. After a simultaneous vote over the two options, the winner must be confirmed by at least one agent from a random sample of agents voting sequentially. The mechanism incentivizes agents to act truthfully as a lottery is held if no agent confirms the outcome. Our mechanism also reduces by almost half the number of stages required for implementation. Furthermore, we extend our results to incomplete information and abstention and introduce additional implementation mechanisms based on the concept of network formation

Optimal policy design for the sugar tax
Kelly Geyskens, Alexander Grigoriev, Niels Holtrop et al. · 2018 · Theoretical Economics · AI summary available

Abstract
Healthy nutrition promotions and regulations have long been regarded as a tool for increasing social welfare. One of the avenues taken in the past decade is sugar consumption regulation by introducing a sugar tax. Such a tax increases the price of extensive sugar containment in products such as soft drinks. In this article we consider a typical problem of optimal regulatory policy design, where the task is to determine the sugar tax rate maximizing the social welfare. We model the problem as a sequential game represented by the three-level mathematical program. On the upper level, the government decides upon the tax rate. On the middle level, producers decide on the product pricing. On the l…

The Relationship between Consumer Theories with and without Utility Maximization
Yuhki Hosoya · 2024 · Theoretical Economics · AI summary available

Abstract
To study the assumption that the utility maximization hypothesis implicitly adds to consumer theory, we consider a mathematical representation of pre-marginal revolution consumer theory based on subjective exchange ratios. We introduce two axioms on subjective exchange ratio, and show that both axioms hold if and only if consumer behavior is consistent with the utility maximization hypothesis. Moreover, we express the process for a consumer to find the transaction stopping point in terms of differential equations, and prove that the conditions for its stability are equal to the two axioms introduced in the above argument. Therefore, the consumer can find his/her transaction stopping point if…

The Core of an Economy with an Endogenous Social Division of Labour
Robert P. Gilles · 2018 · Theoretical Economics · Not summarized yet

Abstract
This paper considers the core of a competitive market economy with an endogenous social division of labour. The theory is founded on the notion of a "consumer-producer", who consumes as well as produces commodities. First, we show that the Core of such an economy with an endogenous social division of labour can be founded on deviations of coalitions of arbitrary size, extending the seminal insights of Vind and Schmeidler for pure exchange economies. Furthermore, we establish the equivalence between the Core and the set of competitive equilibria for continuum economies with an endogenous social division of labour. Our analysis also concludes that self-organisation in a social division of labo…
