The impact of price promotions on sales of unhealthy food and drink products in British retail stores.

We study the health impact of food and beverage price promotion strategies-multi-buy offers and price discounts, typically biased toward unhealthy product categories-in British consumer retail. We are the first to employ econometric models from the marketing literature to analyze the impact of price promotions with a focus on population health. Our dynamic, reduced form demand model incorporates endogenous inventory (stock piling), consumption rates imputed from repeat purchases and allows for unobserved household heterogeneity.

Divided by choice? For-profit providers, patient choice and mechanisms of patient sorting in the English National Health Service.

This paper studies patient choice of provider following government reforms in the 2000s, which allowed for-profit surgical centers to compete with existing public National Health Service (NHS) hospitals in England. For-profit providers offer significant benefits, notably shorter waiting times. We estimate the extent to which different types of patients benefit from the reforms, and we investigate mechanisms that cause differential benefits.

Reducing consumption of unhealthy foods and beverages through banning price promotions: what is the evidence and will it work?

Objective: Increasing prevalence of overweight and obese people in England has led policymakers to consider regulating the use of price promotions on foods high in fat, sugar and salt content. In January 2019, the government opened a consultation programme for a policy proposal that significantly restricts the use of price promotions that can induce consumers to buy higher volumes of unhealthy foods and beverages. These proposed policies are the first of their kind in public health and are believed to reduce excess purchasing and, therefore, overconsumption of unhealthy products.

Alternative Process Routes to Manufacture Porous Ceramics-Opportunities and Challenges.

Porous ceramics can be realized by different methods and are used for various applications such as cross-flow membranes or wall-flow filters, porous burners, solar receivers, structural design elements, or catalytic supports. Within this paper, three different alternative process routes are presented, which can be used to manufacture porous ceramic components with different properties or even graded porosity. The first process route is based on additive manufacturing (AM) of macro porous ceramic components.

Choice in the presence of experts: The role of general practitioners in patients' hospital choice.

This paper considers the micro-econometric analysis of patients' hospital choice for elective medical procedures when their choice set is pre-selected by a general practitioner (GP). GPs have a dual role with regard to elective referrals in the English NHS, advising patients and at the same time taking account of the financial implications of referral decisions on local health budgets. The paper proposes a two-stage choice model that encompasses both patient and GP level optimization.
