Recent literature has documented ChatGPT's\u0000positive impact on productivity in areas where it has strong expertise,\u0000attributable to extensive training datasets, such as the English language and\u0000Python/SQL programming. However, there is still limited literature regarding\u0000ChatGPT's performance in areas where its capabilities could still be further\u0000enhanced. This paper aims to fill this gap. We conducted an experiment in which\u0000economics students were asked to perform writing analysis tasks in a\u0000non-English language (specifically, Thai) and math & data analysis tasks using\u0000a less frequently used programming package (specifically, Stata). The findings\u0000suggest that, on average, participants performed better using ChatGPT in terms\u0000of scores and time taken to complete the tasks. However, a detailed examination\u0000reveals that 34% of participants saw no improvement in writing analysis tasks,\u0000and 42% did not improve in math & data analysis tasks when employing ChatGPT.\u0000Further investigation indicated that higher-ability students, as proxied by\u0000their econometrics grades, were the ones who performed worse in writing\u0000analysis tasks when using ChatGPT. We also found evidence that students with\u0000better digital skills performed better with ChatGPT. This research provides\u0000insights on the impact of generative AI. Thus, stakeholders can make informed\u0000decisions to implement appropriate policy frameworks or redesign educational\u0000systems. It also highlights the critical role of human skills in addressing and\u0000complementing the limitations of technology.","PeriodicalId":501487,"journal":{"name":"arXiv - QuantFin - Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140036201","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}

With\u0000economic globalization and the financialization of agricultural products\u0000continuing to advance, the interconnections between different agricultural\u0000futures have become closer. We utilize a TVP-VAR-DY model combined with the\u0000quantile method to measure the risk spillover between 11 agricultural futures\u0000on the futures exchanges of US and China from July 9,2014, to December 31,2022.\u0000This study yielded several significant findings. Firstly, CBOT corn, soybean,\u0000and wheat were identified as the primary risk transmitters, with DCE corn and\u0000soybean as the main risk receivers. Secondly, sudden events or increased eco-\u0000nomic uncertainty can increase the overall risk spillovers. Thirdly, there is\u0000an aggregation of risk spillovers amongst agricultural futures based on the\u0000dynamic directional spillover results. Lastly, the central agricultural futures\u0000under the conditional mean are CBOT corn and soybean, while CZCE hard wheat and\u0000long-grained rice are the two risk spillover centers in extreme cases, as per\u0000the results of the spillover network and minimum spanning tree. Based on these\u0000results, decision-makers are advised to safeguard against the price risk of\u0000agricultural futures under sudden economic events, and investors can utilize\u0000the results to construct a superior investment portfolio by taking different\u0000agricultural product futures as risk-leading indicators according to various\u0000situations.","PeriodicalId":501487,"journal":{"name":"arXiv - QuantFin - Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140036098","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}

Specifically, we aim to\u0000maximize profit over an arbitrary sequence of multiple demand curves, each\u0000dependent on a distinct ancillary variable, but sharing the same price. A\u0000prototypical example is targeted marketing, where a firm (seller) wishes to\u0000sell a product over multiple markets. The firm may invest different marketing\u0000expenditures for different markets to optimize customer acquisition, but must\u0000maintain the same price across all markets. Moreover, markets may have\u0000heterogeneous demand curves, each responding to prices and marketing\u0000expenditures differently. The firm's objective is to maximize its gross profit,\u0000the total revenue minus marketing costs. Our results are near-optimal algorithms for this class of problems in an\u0000adversarial bandit setting, where demand curves are arbitrary non-adaptive\u0000sequences, and the firm observes only noisy evaluations of chosen points on the\u0000demand curves. We prove a regret upper bound of\u0000$widetilde{mathcal{O}}big(nT^{3/4}big)$ and a lower bound of\u0000$Omegabig((nT)^{3/4}big)$ for monotonic demand curves, and a regret bound of\u0000$widetilde{Theta}big(nT^{2/3}big)$ for demands curves that are monotonic in\u0000price and concave in the ancillary variables.","PeriodicalId":501487,"journal":{"name":"arXiv - QuantFin - Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140036198","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}

In this scenario of labour shortages, our work aims to\u0000understand whether employers have started focusing on individual skills rather\u0000than on formal qualifications in their recruiting. By analysing a large time\u0000series dataset of around one million online job vacancies between 2019 and 2022\u0000from the UK and drawing on diverse literature on technological change and\u0000labour market signalling, we provide evidence that employers have started\u0000so-called \"skill-based hiring\" for AI and green roles, as more flexible hiring\u0000practices allow them to increase the available talent pool. In our observation\u0000period the demand for AI roles grew twice as much as average labour demand. At\u0000the same time, the mention of university education for AI roles declined by\u000023%, while AI roles advertise five times as many skills as job postings on\u0000average. Our regression analysis also shows that university degrees no longer\u0000show an educational premium for AI roles, while for green positions the\u0000educational premium persists. In contrast, AI skills have a wage premium of\u000016%, similar to having a PhD (17%). Our work recommends making use of\u0000alternative skill building formats such as apprenticeships, on-the-job\u0000training, MOOCs, vocational education and training, micro-certificates, and\u0000online bootcamps to use human capital to its full potential and to tackle\u0000talent shortages.","PeriodicalId":501487,"journal":{"name":"arXiv - QuantFin - Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138817817","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}

The\u0000study aims to determine if Russian energy companies can maintain operations in\u0000the solar energy sector without relying on direct state subsidies.\u0000Methodologically, the analysis utilizes established investment metrics such as\u0000Net Present Value (NPV), Internal Rate of Return (IRR), and Discounted Payback\u0000Period (DPP), tailored to reflect the unique technical and economic aspects of\u0000Russian solar energy facilities and to evaluate the influence of\u0000sector-specific risks on project efficiency, using a rating approach. We\u0000examined eleven solar energy projects under ten different scenarios to\u0000understand the dynamics of direct state support, exploring variations in\u0000support cessation, reductions in financial assistance, and the projects'\u0000resilience to external risk factors. Our multi-criteria scenario assessment\u0000indicates that, under the prevailing market conditions, the Russian solar\u0000energy sector is not yet equipped to operate efficiently without ongoing state\u0000financial subsidies. Interestingly, our findings also suggest that the solar\u0000energy sector in Russia has a greater potential to reduce its dependence on\u0000state support compared to the wind energy sector. Based on these insights, we\u0000propose energy policy recommendations aimed at gradually minimizing direct\u0000government funding in the Russian renewable energy market.
