Price effects of a hospital merger: Heterogeneity across health insurers, hospital products, and hospital locations

In most studies on hospital merger effects, the unit of observation is the merged hospital, whereas the observed price is the weighted average across hospital products and across payers. However, little is known about whether price effects vary between hospital locations, products, and payers. We expand existing bargaining models to allow for heterogeneous price effects and use a difference-in-differences model in which price changes at the merging hospitals are compared with price changes at comparison hospitals. We find evidence of heterogeneous price effects across health insurers, hospital products and hospital locations. These findings have implications for ex ante merger scrutiny

Young children’s food brand knowledge. Early development and associations with television viewing and parent’s diet

Brand knowledge is a prerequisite of children’s requests and choices for branded foods. We explored the development of young children’s brand knowledge of foods highly advertised on television – both healthy and less healthy. Participants were 172 children aged 3–5 years in diverse socio-economic settings, from two jurisdictions on the island of Ireland with different regulatory environments. Results indicated that food brand knowledge (i) did not differ across jurisdictions; (ii) increased significantly between 3 and 4 years; and (iii) children had significantly greater knowledge of unhealthy food brands, compared with similarly advertised healthy brands. In addition, (iv) children’s healthy food brand knowledge was not related to their television viewing, their mother’s education, or parent or child eating. However, (v) unhealthy brand knowledge was significantly related to all these factors, although only parent eating and children’s age were independent predictors. Findings indicate that effects of food marketing for un- healthy foods take place through routes other than television advertising alone, and are present before pre-schoolers develop the concept of healthy eating. Implications are that marketing restrictions of un- healthy foods should extend beyond television advertising; and that family-focused obesity prevention programmes should begin before children are 3 years of age

Market innovation as framing, productive friction and bricolage: an exploration of the personal data market

This paper explores the possibilities offered by recent Science and Technology Studies (STS) research on markets for engaging with market innovation. Although there exist few reflections on how innovation happens in markets, market innovation has not been singularly theorized in STS-inspired market studies. In this paper, we explore the potential analytic utility of different sets of ideas in the field of market studies, such as ‘framing’ [Callon, M. (1998) ‘Introduction: the embeddedness of economic markets in economics’, in The Laws of Markets, ed. M. Callon, Blackwell, Oxford, pp. 1–57; Callon, M. (2007) ‘An essay on the growing contribution of economic markets to the proliferation of the social’, Theory, Culture & Society, vol. 24, no. 7–8, pp. 136–163], ‘productive friction’ [Stark, D. (2009) The Sense of Dissonance: Accounts of Worth in Economic Life, Princeton University Press, Princeton, NJ] and ‘bricolage’ [MacKenzie, D. & Pardo-Guerra, J. P. (2014) ‘Insurgent capitalism: Island, bricolage and the re-making of finance’, Economy and Society, vol. 43, no. 2, pp. 153–182]. Drawing on our research into the online personal data industry and start-ups developing personal data control products, we put together five sensibilities that we think are of use for broader considerations of market innovation

Web Vulnerability Study of Online Pharmacy Sites

Consumers are increasingly using online pharmacies, but these sites may not provide an adequate level of security with the consumers’ personal data. There is a gap in this research addressing the problems of security vulnerabilities in this industry. The objective is to identify the level of web application security vulnerabilities in online pharmacies and the common types of flaws, thus expanding on prior studies. Technical, managerial and legal recommendations on how to mitigate security issues are presented. The proposed four-step method first consists of choosing an online testing tool. The next steps involve choosing a list of 60 online pharmacy sites to test, and then running the software analysis to compile a list of flaws. Finally, an in-depth analysis is performed on the types of web application vulnerabilities. The majority of sites had serious vulnerabilities, with the majority of flaws being cross-site scripting or old versions of software that have not been updated. A method is proposed for the securing of web pharmacy sites, using a multi-phased approach of technical and managerial techniques together with a thorough understanding of national legal requirements for securing systems
