Why are drugs more profitable than vaccines? by Michael Kremer( Book )
10 editions published in 2003 in English and held by 49 libraries worldwide
Abstract: In a simple representative consumer model, vaccines and drug treatments yield the same revenue for a pharmaceutical manufacturer, implying that the firm would have the same incentive to develop either ceteris paribus. We provide more realistic models in which the revenue equivalence breaks down for two reasons. First, drug treatments are sold after the firm has learned who has contracted the disease; in the case of heterogeneous consumers who vary with respect to the probability of contracting the disease, there is less asymmetric information to prevent the firm from extracting consumer surplus with drug treatments than with vaccines. We prove that, due to this aspect of pharmaceutical pricing, the ratio of drug-treatment to vaccine revenue can be arbitrarily high; we calculate that the ratio is about two to one for empirical distributions of HIV risk. The second reason for the breakdown of revenue equivalence is that vaccines are more likely to interfere with the spread of the disease than are drug treatments, thus reducing demand for the product. By embedding an economic model within a standard dynamic epidemiological model, we show that the steady-state flow of revenue is greater for drug treatments than for vaccines

When is prevention more profitable than cure? : the impact of time-varying consumer heterogeneity by Michael Kremer( file )
5 editions published in 2013 in English and held by 5 libraries worldwide
We argue that in pharmaceutical markets, variation in the arrival time of consumer heterogeneity creates differences between a producer's ability to extract consumer surplus with preventives and treatments, potentially distorting R&D decisions. If consumers vary only in disease risk, revenue from treatments-sold after the disease is contracted, when disease risk is no longer a source of private information-always exceeds revenue from preventives. The revenue ratio can be arbitrarily high for sufficiently skewed distributions of disease risk. Under some circumstances, heterogeneity in harm from a disease, learned after a disease is contracted, can lead revenue from a treatment to exceed revenue from a preventative. Calibrations suggest that skewness in the U.S. distribution of HIV risk would lead firms to earn only half the revenue from a vaccine as from a drug. Empirical tests are consistent with the predictions of the model that vaccines are less likely to be developed for diseases with substantial disease-risk heterogeneity -- National Bureau of Economic Research web site

An empirical study of pricing strategies in an online market with high-frequency price information by Sara Fisher Ellison( Book )
6 editions published between 2011 and 2014 in English and held by 3 libraries worldwide
We study competition among a score of firms participating in an online market for a commodity-type memory module. Firms were able to adjust prices continuously; prices determined how the firms were ranked and listed (lowest price listed first), with better ranks contributing to firms' sales. Using a year's worth of hourly data, we document the pricing dynamics, cycles, and other patterns in this market. We then characterize empirically the factors which drive price changes, noting clear evidence of firm heterogeneity in the choice of pricing strategy. Finally, we develop a framework for simulating counterfactual market settings, using the simulations to examine counterfactuals involving different mixes of firms according to pricing strategies.

Preventives versus treatments by Michael Kremer( Book )
3 editions published in 2015 in English and held by 2 libraries worldwide
Preventives are sold ex ante, before disease status is realized, while treatments are sold ex post. Even if the mean of the ex ante distribution of consumer values is the same as that ex post, the shape of the distributions may differ, generating a difference between the surplus each product can extract. If, for example, consumers differ only in ex ante disease risk, then a monopolist would have more difficulty extracting surplus with a preventive than with a treatment because treatment consumers, having contracted the disease, no longer differ in disease risk. We show that the ratio of preventive to treatment producer surplus can be arbitrarily small, in particular when the distribution of consumer values has a Zipf shape and the disease is rare. The firm's bias toward treatments can be reversed, for example, if the source of private information is disease severity learned ex post. The difference between the producer surplus earned from the products can result in distorted R & D incentives; the deadweight loss from this distortion can be as large as the entire producer-surplus difference. Calibrations for HIV and heart attacks based on risk factors in the U.S. population suggest that the distribution of disease risk is sufficiently Zipf-similar to generate substantial differences between producer surplus from preventives and treatments. Empirically, we find that proxies for the Zipf-similarity of the disease-risk distribution are associated a significantly lower likelihood of vaccine development but not drug development

Open access as a crude solution to a hold-up problem in the two-sided market for academic journals by Mark J McCabe( Book )
2 editions published in 2016 in English and held by 1 library worldwide
The move from traditional to open-access journals -- which charge no subscription fees, only submission fees -- is gaining support in academia. We analyze a two-sided-market model in which journals cannot commit to subscription fees when authors (who prefer low subscription fees because this boosts readership) make submission decisions. This leads to a hold-up problem, manifested as excessive subscription fees. Open access is a crude attempt to avoid hold up by eliminating subscription fees. We compare the efficiency and profitability of traditional versus open access under various market structures (monopoly, Bertrand competition) and extensions (non-profit journals, bundling, hybrid pricing), using our theoretical findings to understand the evolution of the market for academic journals in the Internet age
