To accomplish this, it is\u0000necessary to establish implementation concepts that detail the timing,\u0000location, and specific measures required to achieve decarbonization. This\u0000restructuring process involves identifying the measures that offer the most\u0000compelling techno-economic and ecological advantages. In particular, measures\u0000that contribute to the interconnection of energy vectors and domains, e.g.\u0000heating, cooling, and electricity supply, in the sense of decentralized\u0000multi-energy systems are a promising future development option. Due to the high\u0000complexity resulting from a multitude of decision options as well as a temporal\u0000coupling across the transformation path, the use of optimization methods is\u0000required, which enable a bottom-up identification of suitable transformation\u0000solutions in a high spatial resolution. For the design of reasonable concepts,\u0000we develop a multistage optimization problem for the derivation of\u0000transformation pathways in the context of a multi-location structure,\u0000expansion, and operation problem. The results show that the heat supply in the\u0000future will mainly be provided by heat pumps with a share of 60%. It can also\u0000be shown that an early dismantling of the gas network will lead to the need for\u0000transitional technologies such as pellet heating. Overall, the conversion of\u0000the municipal energy system can significantly reduce emissions (97%).","PeriodicalId":501487,"journal":{"name":"arXiv - QuantFin - Economics","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138535143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently,\u0000decision-makers are taking proactive measurements to promote diversity,\u0000underscore equity, and advance inclusion. Their unwavering commitment to these\u0000ideals emanates from the following convictions: (i) Diversity encompasses a\u0000broad spectrum of differences; (ii) Equity involves the assurance of equitable\u0000opportunities; and (iii) Inclusion revolves around the cultivation of a sense\u0000of value and impartiality, concurrently empowering individuals. Data-driven AI\u0000tools have been used for screening and ranking processes. However, there is a\u0000growing concern that the presence of pre-existing biases in databases may be\u0000exacerbated, particularly in the context of imbalanced datasets or the\u0000black-box-schema. In this research, we propose a model-driven recruitment\u0000decision support tool that addresses fairness together with equity in the\u0000screening phase. We introduce the term ``pDEI\" to represent the output-input\u0000oriented production efficiency adjusted by socioeconomic disparity. Taking into\u0000account various aspects of interpreting socioeconomic disparity, our goals are\u0000(i) maximizing the relative efficiency of underrepresented groups and (ii)\u0000understanding how socioeconomic disparity affects the cultivation of a\u0000DEI-positive workplace.","PeriodicalId":501487,"journal":{"name":"arXiv - QuantFin - Economics","volume":"78 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138534980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, NFTs have been gaining popularity and at\u0000the same time bringing up issues, such as scams, racism, and sexism.\u0000Decentralization, a key attribute of NFT, contributes to some of the issues\u0000that are easier to regulate under centralized schemes, which are intentionally\u0000left out of the NFT marketplace. In this work, we delved into this\u0000centralization-decentralization dilemma in the NFT space through mixed\u0000quantitative and qualitative methods. Centralization-decentralization dilemma\u0000is the dilemma caused by the conflict between the slogan of decentralization\u0000and the interests of stakeholders. We first analyzed over 30,000 NFT-related\u0000tweets to obtain a high-level understanding of stakeholders' concerns in the\u0000NFT space. We then interviewed 15 NFT stakeholders (both creators and\u0000collectors) to obtain their in-depth insights into these concerns and potential\u0000solutions. Our findings identify concerning issues among users: financial\u0000scams, counterfeit NFTs, hacking, and unethical NFTs. We further reflected on\u0000the centralization-decentralization dilemma drawing upon the perspectives of\u0000the stakeholders in the interviews.

The idea of\u0000creating local groups of citizens, small- and medium-sized companies, and\u0000public institutions, which self-produce and self-consume energy from renewable\u0000sources is at the same time a way to save money for the participants, increase\u0000efficiency of the energy system, and reduce CO$_2$ emissions. Member states\u0000inside the EU are fixing more detailed regulations, which describe, how public\u0000incentives are measured. A natural objective for the incentive policies is of\u0000course to promote the self-consumption of a REC. A sophisticated incentive\u0000policy is that based on the so called 'virtual framework'. Under this framework\u0000all the energy produced by a REC is sold to the market, and all the energy\u0000consumed must be paid to retailers: self-consumption occurs only 'virtually',\u0000thanks a money compensation (paid by a central authority) for every MWh\u0000produced and consumed by the REC in the same hour. In this context, two\u0000problems have to be solved: the optimal investment in new technologies and a\u0000fair division of the incentive among the community members. We address these\u0000problems by considering a particular type of REC, composed by a representative\u0000household and a biogas producer, where the potential demand of the community is\u0000given by the household's demand, while both members produce renewable energy.\u0000We set the problem as a leader-follower problem: the leader decide how to share\u0000the incentive for the self-consumed energy, while the followers decide their\u0000own optimal installation strategy. We solve the leader's problem by searching\u0000for a Nash bargaining solution for the incentive's fair division, while the\u0000follower problem is solved by finding the Nash equilibria of a static\u0000competitive game between the members.","PeriodicalId":501487,"journal":{"name":"arXiv - QuantFin - Economics","volume":"309 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138535152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But\u0000digital innovations like AI and social media increasingly enable societal\u0000harms, from bias to misinformation.

It does\u0000this by expanding negligence and product liability laws. Digital product\u0000developers would be incentivized to mitigate potential algorithmic risks before\u0000deployment to protect themselves and investors.
