This study analyzes gasoline prices in Florida and Georgia before and after Hurricane Irma, a major weather event that affected both states in 2017. The analysis reveals that gasoline prices in both states increased and stabilized well in advance of state of emergency declarations that triggered the states’ price gouging laws. Price gouging laws thus appear to be inconsequential. Free market forces determine prices unhindered by government price controls during hurricane emergencies.

Abstract Gasoline prices in Germany fluctuate significantly within one day. Price ranges of 15 euro cent per day are not uncommon. Consumers therefore often perceive that market power is exercised in the retail fuel market. Especially high surcharges in the late evening are considered to be price gouging. The German Federal Cartel Authority used these price mark-ups as evidence for oligopoly market power in four metropolitan regions between 2007 and 2010. Data for eight metropolises and 65 medium-sized cities from May 2016 to June 2019 show that the lowest price level in the day is reached in the early evening and then rises sharply. We use the well-known Lerner Index to measure market power in these evening hours. Our descriptive analysis shows that the Lerner Indices of the premium brands Aral, Shell, and Total S.A. rise after 10 p.m., that is, after a large part of the price-aggressive gas stations have closed. The results were about 0.1 for diesel and 0.08 for gasoline. Other companies achieve lower values of 0.05–0.07. Compared to other international studies that deal with the fuel market, we find a similar level of Lerner Indices, but only for few hours and not for the whole day. Multivariate estimations cannot show that a larger market share of the analyzed brand or a lower market share of price-aggressive firms increases the index. Influences of weekdays, different cities or wholesale prices cannot be proven either. Therefore, the gasoline market seems to be competitive, at least in a higher dimension as it is publicly perceived. Hence, pricing behavior in the evening and at night cannot be used as evidence of a serious abuse of market power by petrol stations, which could be relevant for the evaluation of future mergers in the petrol market.

The list prices of analogue insulin medicines in the United States have soared during the past decade. In the wake of high-profile cases of prescription medicine “price-gouging”, such as Mylan’s EpiPen and Turing-acquired Daraprim, actors across the insulin supply chain are today facing growing scrutiny from US lawmakers and the wider public. For the most part, however, the role of shareholders in the insulin supply chain has been overlooked. This paper considers the relationship between profits realized from higher insulin list prices, pharmaceutical innovation, and the financial structures of the three dominant insulin manufacturing companies, which set list prices. It shows that despite claims to the contrary, insulin manufacturers extracted vast profits from the sale of insulin products in the period 2009-2018, as insulin list prices rose. Distributions to the company shareholders in the form of cash dividends and share repurchases totaled $122 billion over this period. The paper also considers the role of other actors in the insulin supply chain, such as pharmacy benefits managers (PBMs), in the determination of list prices. The data and analysis presented in the paper indicates that financialization could be considered in tension with not only the development of new drugs that will be available to patients in the future, but also the affordability of products that already exist today.
