We examine whether there is a difference between how MNEs and domestic firms react in heterogeneous local or subnational markets to a global demand shock. Leveraging the 2009-10 H1N1 influenza pandemic as a source of exogenous variation in global demand for influenza vaccines, we investigate the role of subnational heterogeneity in economic resources, industry infrastructure, and political alignment within an emerging economy on the behavior of incumbent MNEs and rival domestic firms. We find that following the pandemic, MNE market share in the influenza vaccine market relative to the non-influenza vaccine markets declines more in regions with lower government health spending per capita, and also in regions unaligned with the federal government. Additional analyses suggest that these changes in market share are not caused by a reduction in MNE revenues. Rather, they are caused by domestic firms that were already present in non-influenza vaccine markets diversifying by entering the highly-related influenza vaccine market. Finally, a granular examination of the differential responses reveals that such responses are not related to pre-shock differences in regional coverage of MNEs and domestic firms. This study contributes to the extant literature by suggesting that the direct costs, or opportunity costs, of new market and region entry are relatively greater for MNEs than for domestic firms, particularly in regions that have inadequate health infrastructure and are politically not aligned.","PeriodicalId":248610,"journal":{"name":"Epidemiology of Human Health & Disease eJournal","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127107550","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 employ a fuzzy regression discontinuity design exploiting the exogenous cut-off value in the diagnosis of T2DM provided by a biomarker (glycated haemoglobin, HbA1c). We make use of unique administrative longitudinal data from Spain and focus on the impact of a diagnosis on clinically measured BMI, smoking and alcohol consumption. We find that, following a T2DM diagnosis, individuals appear to reduce their weight in the short-term. These effects are particularly large among obese individuals and those diagnosed with depression. Patients who are younger, still in the labour market and healthier also present increased short-term probabilities of quitting smoking. In addition, we provide evidence of statistically significant long-term impacts of a T2DM diagnosis on BMI up to three years from the diagnosis. Our results are consistent across parametric and non-parametric estimations with varying bandwidths.","PeriodicalId":248610,"journal":{"name":"Epidemiology of Human Health & Disease eJournal","volume":"18 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114097983","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}

Our paper overcomes these challenges in the context of heart attack treatments in Sweden, where we exploit quasirandom assignment of physicians to patients. We document long learning curves, where physicians keep learning over the first 1000 treatments performed, affecting both proficiency and decision-making skills. These learning effects translate into effects on patient health, but only over the first 150 treatments performed, corresponding to one year of experience. Learning rates are higher for physicians who have worked with more experienced colleagues and who have gained more experience in treating complicated cases. Experienced physicians are more responsive to patient characteristics when deciding on treatments and experience from more recent heart attack treatments is more valuable than experience from more distant ones, suggesting that human capital depreciates. We also show that productivity growth keeps pace with wage growth over the first four years of the career but flattens out thereafter. Our results provide rare evidence on the existence of prolonged learning curves in high-skilled tasks and support the notion that learning-by-doing can be a powerful mechanism for productivity growth.","PeriodicalId":248610,"journal":{"name":"Epidemiology of Human Health & Disease eJournal","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132441498","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}
