The Inflation Reduction Act (IRA) creates a new process to cap Medicare Part D branded drug prices. It prohibits Medicare from paying more than a specified discount from average private market prices and requires that CMS negotiate with manufacturers to agree on a maximum fair price that Medicare will pay that is lower than the specified discount. This article analyzes the cause of high drug prices and how negotiations to set the maximum fair price might unfold. It compares Medicare’s new pricing process to the way drug prices are set in Medicaid, the Veterans Administration, U.S. private insurers, and European nations. It analyzes how negotiations to set the maximum fair price might unfold in light of negotiation theory and the practices to negotiate prices employed in Europe. It draws inferences from the initial published data on the first round of negotiated prices.

This study relies on a linear programming model to estimate welfare ratios in Spain between 1600 and 1800. This method is used to find the food basket that guaranteed the intake of basic nutrients at the lowest cost. The estimates show that working families in Toledo had higher welfare ratios than in those in Barcelona. In addition, the welfare ratios of Spain were always below those of London and Amsterdam. The divergence between Northern Europe and Spain started before the Industrial Revolution and increased over time.

Since early 2021, food prices in Britain have increased by 30%. Using monthly microdata, researchers have found that frictions in the UK’s new trade relationship with the European Union (EU) play an important part in this inflation. The trade relationship is evolving, with further changes expected in 2024. This article establishes a framework for identifying trade-related inflation in close to real time. Using programming techniques, we collect daily prices of over 100,000 supermarket items, covering 80% of the UK grocery market. We identify 1,200 products from 12 countries with a protected designation of origin (PDO). This allows us to link price changes to individual EU economies. Addressing the predominance of EU PDOs, we employ a large language model to discern product origins from additional web-scraped data, thus broadening our analysis to cover over 67,000 products. Since August 2023, we find that prices for EU-originating food products have increased at a rate of 50% higher than domestically sourced products. This study presents a unique methodological approach to dissecting food sector inflation, which is well-positioned to be used in a policy setting, allowing us to assess the possible impact of impending nontariff barriers at the GB-EU border in 2024.

There is evidence of persistent inequalities in household financial protection of health and drugs spending in Latin America. Despite the expansion of coverage, strong inequalities persist in access to health and family spending on drugs in the region. Out-of-pocket spending in medicines is regressive in greater need for affordable medicines.

The impact of product ratings is significant in the experience goods market, whose intangible products are difficult to evaluate before consumption. Product ratings can reduce information asymmetries because they represent a credible signal of quality and thus positively affect product sales. In this study, we shed light on how professional critics behave by focusing on the influence of product characteristics and former reviews on rating behavior and market prices as additional quality signals in wine markets. Using 13,911 observations from professional wine tastings, we analyze 8,444 worldwide-produced wines and their ratings over 20 years. We find clear evidence to suggest that prices and product ratings are significantly related. Finally, the results suggest that review consistency evolves and determines current ratings.

It is commonly asserted that Chinese diets before the market and production reforms of the 1980s contained little or no meat. Yet this nearly universal assumption remains untested: Unlike other forms of material consumption, the question of meat in Chinese diets has received almost no systematic attention from historians. Focusing on the early twentieth century, this article examines who in China ate meat, and how meat consumption was shaped by regional and household patterns. It combines insights from three sorts of data. First, Japanese price surveys from the 1920s show a high degree of variation in the preference for one type of meat over others, and the price availability of meat versus wages or other food products. Second, production data, including slaughterhouse tallies and industry estimates of animal by-products show the seasonality of animal slaughter and the vast scale and dispersed geography of China’s livestock production. Finally, nutrition and diet studies from the 1920 to the late 1940s examine actual household consumption, emphasizing how social forces and cyclical fortunes shaped individual choices. The composite picture from these three perspectives confirms that China’s meat consumption was hardly inconsequential. But more than simply triangulating a result, the exercise of comparing perspectives of price, production, and nutrition also highlights the collection of survey data as a series of historical moments.

The relationship between costs and health benefits of branded pharmaceuticals remains controversial. This paper examines the incremental costs incurred for incremental health benefits gained from the largest available sample of cost-effectiveness studies of branded drugs in the USA, the 1994–2015 Tufts Registry of Cost-Effectiveness Analyses. Earlier studies used small, specialized samples of drugs. We use linear regression analysis to estimate the association in those studies between additional quality-adjusted life years (QALYs) and incremental pharmaceutical costs. The preferred sample uses 476 studies involving branded pharmaceuticals with both higher costs and increased effectiveness compared to the previous standard of care. Regressions of costs on QALYs imply that an additional QALY is associated, on average, with a $28,561 increase in cost (95 % CI, $18,853–$38,270). This regression explains 20 % of the variation in sample costs. In this analytical sample, a share of the variation in the cost of pharmaceuticals is, therefore, not random but rather associated with variation in QALYs; prices are to some extent “value-based.” Our results are robust to varying sample inclusion criteria and to the funding source. In subgroup analyses, the highest cost per QALY was $44,367 (95 % CI, $35,373–$53,361). Costs of pharmaceuticals in this data set are, on average, lower than common estimates of the monetary value of a QALY to American consumers. As in other studies, we find that sellers of patent-protected beneficial new technology appear to capture only a fraction of the benefits provided.

Despite the growth of studies on slavery and slave trade outside the Atlantic world in recent years, especially in the early modern Indian Ocean and Indonesian Archipelago worlds, our knowledge of regional price levels and their development remains surprisingly underdeveloped. This article questions how the price of enslaved people developed in the multi-directional and multi-faceted Indian Ocean and Indonesian Archipelago slave trade, how this compared to the Atlantic world and what this tells us about slave trade and slavery in different parts of the world. Drawing on evidence from a large variety of sources, mainly from the Dutch Indian Ocean and Indonesian Archipelago world, this article expands the body of data significantly and provides for the first time a reconstruction of the level of slave trade prices and their development in several important supplying and demanding slave trade regions in the Indian Ocean and Indonesian Archipelago world and compares these to the development of slave prices in the Atlantic slave trade.

Desde hace algunos años se avanza en investigaciones sobre la evolución, causas y consecuencias de la desigualdad. En ese marco, la desigualdad salarial ha recibido gran atención dadas sus implicancias en relación con las políticas económicas, el crecimiento y el desarrollo. En este artículo se presentan nuevas series y análisis acerca de la desigualdad salarial de género en la industria de la ciudad de Buenos Aires entre 1903 y 1942. Se propone cubrir un área vacante en los estudios del mundo laboral femenino, siempre complejo, y aún más en la primera mitad del siglo XX. Esta aproximación es una aportación a los estudios sobre la desigualdad de género en Argentina, que permitirá comparaciones con otros espacios y regiones.
