We propose a testing protocol to accelerate infection diagnostics by combining multiple samples, and in case of positive results, re-test individual samples. The key insight is that a negative result in the first stage implies negative infection for all individuals. Thus, a single test could rule out infection in multiple individuals. Using simulations, we show that this protocol reduces the required number of testing kits, especially when the infection rate is low, alleviating a key bottleneck for public health authorities in times of pandemics and epidemics such as COVID-19. Our proposed protocol is expected to be more effective when the infection rate is low, which suggests that it is better suited for early stage and large-scale, population-wide testing. However, the managerial trade-off is that the protocol has costs in additional time for returning test results and an increased number of false negatives. We discuss applications of pooled testing in understanding population-wide testing to understand infection prevalence, to diagnose infections in high-risk groups of individuals, and to identify disease cold spots.","PeriodicalId":35878,"journal":{"name":"Vikalpa","volume":"112 1","pages":"13 - 26"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87777772","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}

Consumer purchase of country’s own brand and the products manufactured in their own country plays a vital role in the GDP of that country and help in revival of the country’s economy. This study focuses on understanding the factors that influence consumer’s buying behaviour and model these factors to understand the causal relationship using partial least square-structural equation modelling. An online survey which was carried out between 30 March 2020 and 18 April 2020. A total of 367 responses were collected during this period. Findings of the study indicate that economic nationalism, lockdown sentiments and sustainable approach (LSSA), and product-specific ethnocentric behaviour (PSEB) tendency significantly influence the willingness to buy country’s own brands and products. Present study results reveal that during pandemic consumers have realized the importance of hygiene products, environment-friendly products, regional (local) products, and satisfaction beyond shopping; these factors determine their willingness to buy Indian brands (WBIB)/made-in-India products. Further, post lockdown and post COVID era, consumers feel that buying Indian-made products and encouraging others to buy them would impact and revive the Indian economy constructively. It was also found that the influence of factors such as economic nationalism, LSSA, and PSEB on the WBIB is mediated by attitude towards foreign products. The findings of the study can aid marketing managers in planning appropriate promotion strategies to stimulate ethnocentric tendency, and cues can be provided to invoke a sense of economic nationalism in consumers when they buy products or services.","PeriodicalId":35878,"journal":{"name":"Vikalpa","volume":"26 1","pages":"27 - 40"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83230571","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 data from two regions of the Indian state of Andhra Pradesh—Rayalaseema (a relatively dry forest region with low income) and the coastal region (relatively fertile forest and with higher income). We also identify socio-economic determinants of their patience levels and factors which distinguish the two regions. To elicit individual discount rates of FDCs members and their determinants, we use the choice task design methodology. Members from both regions were found to be highly impatient using the standard choice task design with the revealed time discount rate averaging 800% per annum. Members of FDCs from Rayalaseema were more impatient than their counterparts from the coastal region, although the statistical evidence is weak. We find no association between the income of members of FDCs and their time discount rate for both regions. Membership to caste categories showed a different response in both the regions, with members from the Scheduled Caste category and Other Backward Classes found to have a lower discount rate than those from the Scheduled Tribes category of Rayalaseema region and vice versa for the coastal region. For the coastal region, those with larger family size and heads of households were found to have a lower discount rate.","PeriodicalId":35878,"journal":{"name":"Vikalpa","volume":"5 1","pages":"193 - 206"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81318106","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}
