    A distributed coordination mechanism for supply networks with asymmetric information

    The paper analyses the problem of coordination in supply networks of multiple retailers and a single supplier, where partners have asymmetric, private information of demand and costs. After stating generic requirements like distributedness, truthfulness, efficiency and budget balance, we use the apparatus of mechanism design to devise a coordination mechanism that guarantees the above properties in the network. The resulting protocol is a novel realisation of the widely used Vendor Managed Inventory (VMI) where the responsibility of planning is at the supplier. We prove that together with the required generic properties a fair sharing of risks and benefits cannot be guaranteed. We illustrate the general mechanism with a detailed discussion of a specialised version, assuming that inventory planning is done according to the newsvendor model, and explore the operation of this protocol through computational experiments

    Decentralized Decision Making for Limited Resource Allocation Using a Private Blockchain Network in an IoT (Internet of Things) Environment with Conflicting Agents

    Blockchains have gotten popular in recent times, owing to the security, anonymity, and lack of any third-party involvement. Blockchains essentially are record keeping tools that record any transactions between involved parties. One of the key aspects of handling and navigating of any autonomous traffic on the streets, is secured and simple means of communication. This thesis explores distribution of minimum resources between multiple autonomous agents, by settling conflicts using events of random nature. The thesis focusses on two specific events, tossing of a coin and the game of rock, paper, and scissors (RPS). An improvement on the traditional game of RPS is further suggested, called rock, paper, scissors, and hammer (RPSH). And then seamless communication interface to enable secure interaction is setup using blockchains with smart contracts. A new method of information exchange called Sealed Envelope Exchange is proposed to eliminate any involvement of third-party agents in the monitoring of conflict resolution. A scenario of assigning the sole remaining parking spot in a filled parking space, between two vehicles is simulated and then the conflict is resolved in a fair manner without involving a third-party agent. This is achieved by playing a fair game of RPSH by using blockchains and simulating cross chain interaction to ensure that any messages and transactions during the game are secured

    The impact of artificial intelligence on the nature and quality of jobs. Bruegel WORKING PAPER | ISSUE 14/2022 | 27 JULY 2022.

    Artificial intelligence (AI), like any workplace technology, changes the division of labour in an organisation and the resulting design of jobs. When used as an automation technology, AI changes the bundle of tasks that make up an occupation. In this case, implications for job quality depend on the (re)composition of those tasks. When AI automates management tasks, known as algorithmic management, the consequences extend into workers’ control over their work, with impacts on their autonomy, skill use and workload. We identify four use cases of algorithmic management that impact the design and quality of jobs: algorithmic work-method instructions; algorithmic scheduling of shifts and tasks; algorithmic surveillance, evaluation and discipline; and algorithmic coordination across tasks. Reviewing the existing empirical evidence on automation and algorithmic management shows significant impact on job quality across a wide range of jobs and employment settings. While each AI use case has its own particular effects on job demands and resources, the effects tend to be more negative for the more prescriptive (as opposed to supportive) use cases. These changes in job design demonstrably affect the social and physical environment of work and put pressure on contractual employment conditions as well. As technology development is a product of power in organisations, it replicates existing power dynamics in society. Consequently, disadvantaged groups suffer more of the negative consequences of AI, risking further job-quality polarisation across socioeconomic groups. Meaningful worker participation in the adoption of workplace AI is critical to mitigate the potentially negative effects of AI adoption on workers, and can help achieve fair and transparent AI systems with human oversight. Policymakers should strengthen the role of social partners in the adoption of AI technology to protect workers’ bargaining power

    Community Enforcement of Informal Contracts: Jewish Diamond Merchants in New York

    The diamond industry is home to many unusual features: the predominance of an ethnically homogeneous community of merchants, the norm of intergenerational family businesses, and a rejection of public courts in favor of private contract enforcement. This paper explains that the diamond industry\u27s unique attributes arise specifically to meet the particularly rigorous hazards of transacting in diamonds. Since diamonds are portable, easily concealable, and extremely valuable, the risk associated with a credit sale can be especially costly. However, the industry enjoys valuable organizational efficiencies if transactions occur on credit between independent, fully incentivized agents. Thus, an efficient system of exchange will find ways to induce merchants who purchase on credit to fulfill their payment obligations. The very features that give the diamond industry an unusual profile are responsible for providing institutions to support credit sales. A system of private arbitration spreads information regarding merchants\u27 past dealings, so a reputation mechanism to monitor merchants can take hold. Intergenerational legacies, though restricting entry only to those who can inherit good reputations from family members, resolve an end-game problem and induce merchants to deal honestly through their very last transaction. And the participation of Ultra-Orthodox Jews, for whom inclusion and participation in their communities is equally paramount to their material wealth, serve important value-added services as diamond cutters and brokers without posing the threat of theft and flight
