The Cost

This article addresses the cost associated to defence, i.e., the resources that societies shall allocate to provide security to their members. It examines the methods and ways for setting and distributing these resources to obtain enough military capabilities for sustaining the perception of security of the citizens. The choice of an allocation that optimises social welfare is rather old and of constant concern. The main novelty of this article is exploring this problem from the bounded rationality of the human being, the imperfect information available, the choices unsupported by economic rationality and the constrained effectiveness of institutions and norms. These issues may drive to allocations that do not necessarily achieve the largest welfare.

The Cost

With the development of distributed generation and demand-side response, traditional consumers are now converted into prosumers that can actively produce and consume electricity. Moreover, with the help of energy integration technique, prosumers are encouraged to form a multi-energy community (MEC), which can increase their social welfare through inside multi-energy sharing. This paper proposes a day-ahead cooperative trading mechanism in a MEC that depends on an energy hub (EH) to couple electricity, natural gas, and heat for all prosumers. The model of the traditional uncooperative local integrated energy system (ULIES) is also built as a comparison. A satisfaction-based profit distribution mechanism is set according to prosumers’ feelings about the extra cost they save or extra profit they gain in MEC compared with that in ULIES. Finally, case studies are set to analyze the utility of MEC in enlarging social welfare, after considering the effects of prosumers’ electricity usage patterns and buy-and-sell prices in retail market. The results of satisfaction-based profit distribution are also analyzed to verify that it can save the cost or increase the profit of each prosumer and EH.

Different Levels

With the rapid development of information technology, digital platforms can collect, utilize, and share large amounts of specific information of consumers. However, these behaviors may endanger information security, thus causing privacy concerns among consumers. Considering the information sharing among firms, this paper constructs a two-period duopoly price competition Hotelling model, and gives insight into the impact of three different levels of privacy regulations on industry profit, consumer surplus, and social welfare. The results show that strong privacy protection does not necessarily make consumers better off, and weak privacy protection does not necessarily hurt consumers. Information sharing among firms will lead to strong competitive effects, which will prompt firms to lower the price for new customers, thus damaging the profits of firms, and making consumers’ surplus higher. The level of social welfare under different privacy regulations depends on consumers’ product-privacy preference, and the cost of information coordination among firms. With the cost of information coordination among firms increasing, it is only in areas where consumers have greater privacy preferences that social welfare may be optimal under the weak regulation.

This book examines how the law of torts, contracts, and restitution can be improved by showing how private law reduces the cost of accidents, lubricates bargains, and encourages unrequested benefits. It considers the two pervasive rules of tort law that provide incentives for actors to reduce accident costs: strict liability and negligence. It also explains how contract law achieves effiency through the remedy of damages and how restitution law allows benefactors to recover gains that their beneficiaries wrongfully obtained from them. The book makes three central claims: misalignments in tort law should be removed; in contract law, promisee's incentives should be improved; and the law should recognize some right of compensation for those who produce unrequested benefits. Each claim is based on the desire to reform private law and to make it more effective in promoting social welfare.

Commitment Device

Behavior-based pricing (BBP) refers to the practice in which firms collect consumers’ purchase history data, recognize repeat and new consumers from the data, and offer them different prices. This is a prevalent practice for firms and a worldwide concern for consumers. Extant research has examined BBP under the assumption that consumers observe firms’ practice of BBP. However, consumers do not know that specific firms are doing this and are often unaware of how firms collect and use their data. In this article, the authors examine (1) how firms make BBP decisions when consumers do not observe whether firms perform BBP and (2) how the transparency of firms’ BBP practice affects firms and consumers. They find that when consumers do not observe firms’ practice of BBP and the cost of implementing BBP is low, a firm indeed practices BBP, even though BBP is a dominated strategy when consumers observe it. When the cost is moderate, the firm does not use BBP; however, it must distort its first-period price downward to signal and convince consumers of its choice. A high cost of implementing BBP serves as a commitment device that the firm will forfeit BBP, thereby improving firm profit. By comparing regimes in which consumers do and do not observe a firm’s practice of BBP, the authors find that transparency of BBP increases firm profit but decreases consumer surplus and social welfare. Therefore, requiring firms to disclose collection and usage of consumer data could hurt consumers and lead to unintended consequences.

Consumers experience a sense of loss when a product’s quality does not match their expectations. To alleviate consumer loss aversion (CLA), firms can disclose information to reduce consumers’ uncertainty about product quality and the resulting psychological loss. In this paper, we investigate the implications of CLA on firm profit, consumer surplus, and social welfare when firms endogenously make quality disclosure decisions. We find that CLA leads symmetric firms to disclose quality more often. Given that CLA weakly reduces consumers’ utility from buying a product and quality disclosure is costly, intuition suggests that CLA is detrimental to firms. We find that this intuition is true only in a monopoly. Surprisingly, CLA makes both firms in a competition better off. Moreover, CLA increases firms’ profit when they invest in quality disclosure instead of money-back guarantees to respond to CLA. We also find that CLA decreases consumer surplus and social welfare. Therefore, educating consumers to improve decision-making skills by deliberating on future outcomes and emotions can benefit firms at the cost of consumers and society. When firms disclose quality sequentially, CLA can discourage the follower from disclosing quality. A strong level of CLA increases the leader’s profit over the follower’s, thereby encouraging firms to be the first mover in quality disclosure. This paper was accepted by Juanjuan Zhang, marketing.

This qualitative study explored how volunteers delivering social welfare to orphans and vulnerable children through a community initiative supported by donors made sense of volunteering during a period of hyperinflation in Zimbabwe. Findings confirm that volunteering in Africa is influenced by a normative value system embedded in Ubuntu. Volunteering emerged as contradictory given the contextual prevalence of the social obligation discourse rather than individual choice as embedded in the European sense of voluntarism. Volunteering masked the cost of participation, thereby potentially making poverty worse for the poor in a context without a formal welfare system.

Commitment Device

AbstractThis Article argues that the act of formally declaring war entails a measure of explicit commitment on the part of American political actors that raises the cost of failure and motivates politicians to see engagements through to a decisive end, fulfilling the role of a contract or institutional commitment device. It argues that undeclared conflicts, lacking such a device, are more likely to end on less decisive and less favorable terms to the United States. On this basis, it explains the emergence of a decades-long trend of protracted, unsuccessful, and indecisive military engagements by the United States as having emerged from the erosion of a constitutionally established separation of powers with respect to the initiation and administration of foreign military conflicts. In defense of this theory, it uses case studies to assess the relevance of its predictions and to weigh potential objections involving selection bias and imperfect information.
