The paper employed dynamic conditional correlation and asymmetric generalized dynamic conditional correlation models to examine the bidirectional volatility spillover. The study preferred these sophisticated and flexible models as they have several advantages over other econometric models. The findings of the study indicate a long-term integration and a significant bidirectional spillover effect (both symmetric and asymmetric), suggesting a close relationship among the stock markets of BRICS countries. Consequently, diversifying one's portfolio between these markets would not yield substantial economic value for investors. Also, the study finds the same pattern of flow in asymmetric volatility spillover but at a different significance level. To the best of the authors' knowledge, this is the first study investigating the asymmetric volatility spillover effect among BRICS countries' stock indices using the DCC-MGARCH and AGDCC-MGARCH models.</p>","PeriodicalId":43923,"journal":{"name":"Decision","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139374812","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 study uses secondary data accessed from the Prowess IQ database for the period from 1995–1996 to 2019–2020, and employs parametric approach based on the estimation of the Cobb–Douglas production function to measure productivity. The analysis reveals that the overall productivity of Indian pharmaceutical firms has increased during the post-patent years. Comparison of TFP across different sizes of firms reveals that in both the pre-and post-patent periods, large firms exhibit higher productivity than their medium and smaller counterparts. Estimation of TFP growth shows that during the pre-patent period, all firms, irrespective of their sizes, have recorded negative growth rates. However, a positive turnaround is observed in the growth rates of all firms during the post-patent years. Econometric exercise shows that industrial concentration, age of the firm, firm-size, capital intensity, R&D intensity, export intensity, imported raw materials intensity, and profit intensity are the important variables exercising a significant influence on firm productivity, though their direction and strength of influence differ.</p>","PeriodicalId":43923,"journal":{"name":"Decision","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139374806","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}

We present two experiments that examined whether the objective probability of a trick occurring by chance in fl uences how people experience the trick. In Experiment 1, participants watched different versions of a magic trick in which we manipulated the statistical probability of the trick occurring by chance. We found that the objective probability had no signi fi cant impact on how much people enjoyed the trick or how impressed they were by it. Our participants enjoyed the trick equally when there was a 25% chance of it succeeding by chance as when it was virtually impossible. The same was true for how impressed they were by the performance. However, tricks that were less likely to succeed by chance were rated as more dif fi cult and impossible. More implausible tricks resulted in more participant explanations stating they did not know how the trick was done, as well as explanations implying it was fake. In a follow-up experiment, participants were presented with vignettes describing the same trick, and they were asked to judge the magician ’ s chances of succeeding. The statistical probability of the trick occurring by chance did not affect these judgments adversely, but they did do so when the same feat was performed by a nonmagician.","PeriodicalId":43923,"journal":{"name":"Decision","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136113572","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}
