RESUMO
Alcohol consumption, associated with various cancers, mental disorders, and aggressive behavior, leads to three million deaths globally each year. In Brazil, the alcohol per capita consumption among drinkers aged 15 and over is 41.7 g of pure alcohol/day (~1 L beer/day), which falls into the risky consumption category and exceeds the global average by almost 30%. An effective way to mitigate alcohol-related harm is to increase its retail price. This study assesses the costs of consuming leading brands of beer and sugarcane spirit cachaça (Brazil's most popular alcoholic beverages) against the expenditure on staple foods. Data on food and alcoholic beverage prices were collected in João Pessoa, Brazil, for 2020 and 2021. The cost per gram of pure alcohol and food were considered to establish consumption patterns of 16.8 g/day (moderate), 41.7 g/day, and 83.4 g/day (heavy), distributed in three scenarios involving the beverages alone or combined (64% beer and 36% cachaça), and a balanced 2000 kcal/day staple diet. The study finds that all heavy consumption scenarios cost less or significantly less (cachaça alone) than a 2000 kcal/day staple diet, highlighting an urgent need for fiscal policies, such as a minimum unit pricing for alcohol, to address public health concerns.

Diferencias en las características de la infraestructura verde pueden variar la relación entre los espacios verdes urbanos y el precio de la vivienda (PV). El objetivo de este estudio es estimar el efecto de la proximidad de áreas verdes con diseño antrópico (AVDA) y de un humedal, sobre los valores del mercado de vivienda. Mediante uso de sistemas de información geográfica se determinó el tamaño de áreas verdes próximas al humedal y otros atributos de localización de las viviendas; los precios de los inmuebles se obtuvieron en el mercado de finca raíz en Bogotá. Con mínimos cuadrados ordinarios se relacionó el PV con atributos ambientales, de localización y socioeconómicos; el Índice de Moran, modelos de contigüidad y error espaciales permitieron analizar la dependencia espacial de los datos. El AVDA y no el humedal, estuvo significativamente asociada con el PV Las regresiones realizadas mostraron la ausencia de dependencia espacial entre los datos, así como una asociación positiva del PV con las AVDA, el área del inmueble y el número de alcobas. Mientras que la edad de las viviendas y la distancia al Comando de Atención Inmediata (CAI) tuvieron una asociación negativa con el PV. Estos resultados muestran que los residentes locales pagan más por vivir cerca a áreas con AVDA y tienen implicaciones para la planificación urbana de estratos socioeconómicos altos. Los valores estimados en este trabajo pueden ser utilizados para alimentar un análisis costo-beneficio en evaluaciones para la construcción, ampliación y rehabilitación de espacios verdes urbanos. Se recomienda realizar un estudio semejante, en vecindarios de menores ingresos económicos que permitan definir también la tipología de AVDA factible de pagar y que al mismo tiempo proporcione servicios ecosistémicos culturales.
Differences in the characteristics of green infrastructure can vary the relationship between urban green spaces and housing prices. The objective of this study is to estimate the effect of the proximity of anthropically designed green areas and a wetland on housing market values. Using geographic information systems, the size of green areas near the wetland and other attributes of housing location were determined; property prices were obtained from the real estate market in Bogota. Ordinary least squares was used to relate the housing prices to environmental, location and socioeconomic attributes; the Moran Index, contiguity models and spatial error models were used to analyze the spatial dependence of the data. The anthropically designed green areas, and not the wetland, was significantly associated with the housing prices. The regressions performed showed the absence of spatial dependence among the data, as well as a positive association of housing prices with anthropically designed green areas, property area and number of alcoves. While the age of the dwellings and the distance to the Immediate Attention Command had a negative association with housing prices. These results show that local residents pay more to live near areas with anthropically designed green areas and have implications for urban planning for high socioeconomic strata. The values estimated in this work can be used to feed a cost-benefit analysis in evaluations for the construction, expansion, and rehabilitation of urban green spaces. It is recommended that a similar study be conducted in lower income neighborhoods to define the type of anthropically designed green areas that can be afforded and at the same time provide cultural ecosystem services.
As diferenças nas características da infra-estrutura verde podem variar a relação entre o espaço verde urbano e os preços da habitação (PH). O objetivo deste estudo é estimar o efeito da proximidade de áreas verdes antropogenicamente projetadas (AVAP) e de um pântano sobre os valores do mercado imobiliário. Usando sistemas de informação geográfica, foi determinado o tamanho das áreas verdes próximas ao pântano e outros atributos de localização habitacional; os preços dos imóveis foram obtidos do mercado imobiliário em Bogotá. Os mínimos quadrados comuns foram usados para relacionar a PV aos atributos ambientais, de localização e sócio-econômicos; os modelos do Índice Moran, contiguidade e erro espacial foram usados para analisar a dependência espacial dos dados. A AVAP e não a zona úmida, foi significativamente associada à PV. As regressões mostraram a ausência de dependência espacial entre os dados, bem como uma associação positiva de PH com AVAP, área da propriedade e número de alcovas. Enquanto a idade das moradias e a distância até o Comando de Atenção Imediata (CAI) tinham uma associação negativa com o PV Estes resultados mostram que os residentes locais pagam mais para viver perto de áreas com AVAP e têm implicações no planejamento urbano para altos estratos sócio-econômicos. Os valores estimados neste trabalho podem ser usados para alimentar uma análise de custo-benefício em avaliações para a construção, extensão e reabilitação de espaços verdes urbanos. Recomenda-se que seja realizado um estudo semelhante nos bairros de menor renda para também definir o tipo de AVAP que pode ser oferecido ao mesmo tempo em que fornece serviços culturais ecossistêmicos.
RESUMO
This article analyzes the pricing of innovations in the Brazilian stock market during periods of economic uncertainty. Cross-sectional data were analyzed using the generalized method of moments technique, and our findings indicate that during such periods, innovations negatively impact excess stock returns. Furthermore, our findings suggest that innovations during economic uncertainty improve the pricing of financial assets, making them a significant risk factor. These results are corroborated by those for the Corporate Sustainability Index and the Small Caps Index in the robustness analysis.
RESUMO
ABSTRACT: This study aimed to price croplands in Rio Grande do Sul State (southern Brazil) and point which variables had the most significant impact on prices. The main purpose was achieved using multiple linear regression and principal component analysis. The variables used in this study were planted area, production, price, and yield of the commodities soybean, wheat, and corn. The period under analysis was from January 1994 to December 2017 (biannual observations). Multiple linear regression showed that five variables contributed to land pricing, being three related to soybean and two to wheat. Multivariate analysis grouped the investigated variables into clusters and indicated their influence, in addition to providing information on land prices and reducing variable dimensionality from fourteen original variables to three principal components to be analyzed. The two analyses complemented each other so that the croplands' price was explained by three variables, in which two corroborated in constructing the pricing model for croplands.
RESUMO: Este estudo teve como objetivo a precificação de terra para lavouras no Rio Grande do Sul e apresentar quais variáveis possuem maior impacto no preço. O objetivo foi alcançado por meio da aplicação da análise de regressão linear múltipla e de componentes principais. Variáveis relacionadas às commodities soja, trigo e milho, como a área plantada, produção, cotação e rendimento, formaram o banco amostral para as duas metodologias, compreendendo o período de janeiro de 1994 a dezembro de 2017, em observações bianuais. A regressão linear múltipla mostrou que três variáveis relacionadas à soja e duas ao trigo contribuem na precificação das terras. A análise multivariada agrupou as variáveis investigadas, indicando a influência entre as mesmas, fornecendo informações sobre o preço de terras e diminuindo a dimensionalidade do problema de 14 variáveis originais para três componentes a serem analisados. As duas análises se complementaram de forma que o preço de terras foi explicado por três variáveis e duas corroboraram na construção do modelo de precificação das lavouras.

Expectations about a destination influence the tourist experience during the travel process stages. In the post-COVID-19 normalcy, people are adjusting their priorities and social values. Therefore, it becomes crucial to identify tourists' expectations before traveling. The objectives of this research were: (a) identify the preferences of tourists; (b) establish the attitudes of tourists; and (c) determine the expectations of tourists for post-COVID-19 destination selection. The study analyzed a sample of 491 people during pandemic lockdowns in Guayaquil, Ecuador. Statistical techniques such as exploratory and confirmatory factor analysis were used in data analysis. The results show that after the pandemic, tourists prefer urban tourism, followed by cultural tourism and traveling with relatives. It also shows a more responsible and supportive attitude when traveling. Likewise, the results support the dimensional structure that explains a set of post-pandemic tourist expectations. Five factors were identified: Smart Care, pricing strategy, safety, comfort, and social distancing. Finally, the theoretical and managerial implications of the results that will guide for tourism destination managers were discussed.

Resumo Evitar sobrepreços e preços manifestamente inexequíveis são dois objetivos principais da recém-promulgada Lei nº 14.133, de 1º de abril de 2021. O presente artigo demonstra que, ao tentar alcançar o primeiro objetivo, a nova lei de licitações promove o segundo, pois um comando específico tende a reduzir os preços até congelá-los nos menores valores possíveis, conduzindo os contratados à maldição do vencedor. Alerta-se os agentes públicos sobre o fato de que a manutenção desse comando levará a descumprimentos generalizados de contratos e a uma eventual falência de competidores. O método Monte Carlo é utilizado para demonstrar que um mecanismo abrangente de pesquisa de preços evitará o problema e garantirá o efeito pretendido pela lei.
Resumen Evitar los sobreprecios y los precios manifiestamente inviables son dos de los principales objetivos de la recién promulgada Ley 14.133/2021 de Brasil. Este artículo demuestra que, al intentar lograr el primer objetivo, la nueva ley de licitaciones promueve el segundo, ya que un comando específico tiende a reducir los precios hasta congelarlos a los valores más bajos practicables, llevando a los contratados a la maldición del ganador. Se advierte a los funcionarios públicos que mantener este comando conducirá a incumplimientos generalizados de contratos y eventual quiebra de los competidores. Se utiliza el método Monte Carlo para demostrar que un mecanismo integral de investigación de precios evitará el problema y garantizará el efecto buscado por la ley.
Abstract Avoiding overpricing and irresponsible pricing are two central objectives of the recently enacted Law 14133/2021. This article shows that when trying to achieve the first objective, the new Brazilian public procurement law promotes the second, since a specific command reduces maximum prices until they freeze to the lowest possible values, leading the contractors to the winner's curse. Public officials are warned that maintaining this command will lead to widespread breaches of contracts and eventual bankruptcy of contractors. The Monte Carlo method is adopted to show that a comprehensive price database will avoid the problem and guarantee the effect intended by the law.

Introduction: The transparency of data on the value chain of medicines is crucial for the study and monitoring of the pharmaceutical system. These data may impact medicine pricing negotiations, contribute to patient access to pharmaceutical products, and strengthen health systems. Objective: This study analyzed the national strategies to ensure the transparency of data from medicine cost development to marketing in Argentina, Brazil, and Colombia. Method: A descriptive study was carried out by searching databases, reports, documents, and scientific articles published between January and August 2022 related to rules on transparency and databases, including 1) marketing authorization; 2) pricing; 3) intellectual property; 4) clinical trials; 5) research and development (R&D); and 6) health technology assessment (HTA) of selected biopharmaceuticals. Results: Transparency data, rules, and information are not uniform. The infostructures (organizational capacity for collecting and distributing information) regarding the pharmaceutical value chain in these three countries face limitations in appropriate measures to publicly share data and evidence, including pre-clinical data, clinical data, and costs. None of the countries require transparency about data on research and development costs. All three countries present similar publicization of data on marketing authorization and intellectual property, with some differences. The significant limitations in Argentina include the absence of formal price regulation and data on the volume of medicine purchased and respective amounts paid. Among the three countries, Brazil showed a higher degree of information transparency, perhaps due to the legal regulation that guarantees citizens access to information of public interest. Brazil also stands out in terms of the public availability of HTA reports and pricing, in addition to the highest volume of information. In contrast, Colombia has in place a decree that allows 5 years of trial data exclusivity for new medicines, an act contrary to data transparency. Despite the different stages of transparency, no country has evidenced a robust use of these data in public policy decision-making. Conclusion: The results reinforce the presence of information asymmetry between stakeholders, data fragmentation, data gaps and overlap, and difficulty in comparing available data across the three countries and the use of these data nationally to produce evidence.
RESUMO
Objetivos: Comparar os critérios de formação de preços de medicamentos no Brasil e em países selecionados, analisar o mecanismo de formação de preços de medicamentos no Brasil e analisar o mecanismo de formação de preços de medicamentos em países selecionados. Métodos: Foi realizada uma revisão narrativa da literatura por meio do levantamento de informações em bases de dados, em sites das agências nacionais e organismos internacionais e em literatura "cinzenta", a respeito dos sistemas de saúde e mecanismos de formação de preços de medicamentos no Brasil e nos países selecionados (Austrália, Canadá, Espanha, Estados Unidos, França, Grécia, Itália, Nova Zelândia e Portugal). Resultados: A maioria dos países pesquisados utiliza o referenciamento externo e interno de preços, realiza ajustes e correções de preços ao longo do tempo e faz estudos de avaliação econômica. O valor da terapia ou seu benefício para o paciente ou sistema de saúde é um fator importante tanto na determinação do preço como da incorporação no sistema de saúde. Conclusão: Este trabalho permitiu identificar as semelhanças entre as práticas recomendadas e implementadas internacionalmente e as realizadas no Brasil, bem como os problemas relacionados à definição de preços das novas terapias, além das lacunas no modelo regulatório atual
Objectives: To compare the criteria for setting prices of medicines in Brazil and in selected countries, to analyze the mechanism for setting prices of medicines in Brazil and to analyze the mechanism for setting prices of medicines in selected countries. Methods: A narrative review of the literature was carried out by collecting information in databases, on websites of national agencies and international organizations and in "gray" literature, regarding health systems and price formation mechanisms of medicines in Brazil and selected countries (Australia, Canada, Spain, United States, France, Greece, Italy, New Zealand and Portugal). Results: Most of the countries surveyed use external and internal price referencing, make price adjustments and corrections over time and carry out economic evaluation studies. The value of therapy or its benefit to the patient or health care system is an important factor in both pricing and incorporation into the health care system. Conclusion: This work allowed identify the similarities between the practices recommended and implemented internationally and those carried out in Brazil, as well as the problems related to the pricing of new therapies, in addition to the gaps in the current regulatory model

OBJECTIVES: To characterize at a global level the concept of therapeutic value (TV) and describe the experience of value-based pricing (VBP) policies in 6 reference countries. METHODS: We conducted a rapid review of the literature that addressed 2 exploratory research questions. A systematic and exhaustive search was carried out up to July 2018 in MEDLINE (Ovid), Embase, Scopus, and Web of Science. RESULTS: The concepts of TV and VBP are related; value frameworks for medicines should include social preferences, comparative effectiveness, safety, adoption viability, social impact, high quality of evidence, severity of illness, and innovation. The added therapeutic value (ATV) is the manner of measuring the therapeutic advantages of new medicines compared with existing ones in terms of comparative effectiveness and safety. There are variations in the mechanisms of reimbursement and drug pricing regulation between the countries of study. CONCLUSION: In a VBP system it is essential to establish the TV and ATV of a new medicine. Although there are no methodological guidelines for the implementation of VBP policies, the process implies from the beginning the definition of TV categories that will be included in the drug pricing and reimbursement systems. Agreements between the pharmaceutical industry and governments have become a useful tool as a negotiating mechanism in most countries.

The high cost of drugs for hepatitis C limits access and adherence to treatment. In 2017, the Colombian health care system decided to design a strategy. It consisted of centralized purchasing, regulations, clinical practice guidelines, and direct observation of the treatment and follow-up of patients. The main objective of this study was to assess the centralized purchasing strategy in Colombia. The study design was a policy implementation assessment. We analyzed the change in prices, the clinical outcomes, and the opinions of stakeholders using data from the Ministry of Health. Additional information about effectiveness came from the Colombian Fund for High-Cost Diseases and semi-structured interviews of the stakeholders. The follow-up was from October, 2017 to October, 2018. The total number of patients reported in the cohort period was 1069. The number that finished 12 weeks of treatment, completed the follow-up for the case closure, and were considered cured through the end of October, 2018 was 563 (53%). The remainder, 506 patients (47%), are currently in treatment. A total of 543 of these treated patients (96%) were cured. After implementing this strategy, the drug prices decreased by more than 90% overall. Before implementation, the total direct cost was $100 102 171.75 dollars. Afterward, the cost was $8 378 747 dollars.

Regulation of drug prices that ensures adequate access to effective treatments and promotes innovation is a global challenge. In the United States, the government does not regulate drug prices when they come onto market. On the other hand, in countries such as France and Brazil, government agencies are responsible for setting up price limits by leveraging the interests of the companies and the countries' population. In Brazil, safety and efficacy of drugs are regulated by the Brazilian Health Regulatory Agency, and drug prices are regulated by the Pharmaceutical Market Regulation Chamber with a participation of Brazilian Health Regulatory Agency. Here, we introduce the current challenges faced by the Brazilian government in the drug price regulation and present proposed initiatives aiming to streamline access to innovative treatments for its citizens.

ABSTRACT: Water is an essential input for any agribusiness, used for various purposes such as hygiene procedures, heat exchangers and beverage formulation. Water charging, regulated in Brazil by the National Water Resources Policy (Federal Law 9.433/97), is an important issue for the food industry, since it may change the profile of food production costs. Thus, this article aimed to estimate the price increases in the dairy industry from the use of water charging and evaluate the potential benefit of this collection, comparing it to some planned investments in basins plans. We used a case study of a dairy that produced 1 t/d of mozzarella cheese in the state of Minas Gerais. Results indicated that water charging among the basins with current collection models may vary up to 131%. The increase in price related to water charging was low (0.04-0.09% of production costs), indicating that it can be absorbed by the industry. Conversely, values collected by the basins may be decisive for implementation of several actions aiming an average quantity and quality of water, which is good for the industry, itself. In the current charging collection models in the state of Minas Gerais, it is possible to recognize that collection is a promising initiative for the economical valuation of water. However, charging still seems to lack sufficiency in safety and a rationalization for its use.
RESUMO: A água é um insumo essencial para qualquer agroindústria, utilizada para diversas finalidades, como em procedimentos de higienização, trocadores de calor e formulação de bebidas. Dessa forma, a cobrança pelo uso da água bruta, regulamentada no Brasil pela Política Nacional de Recursos Hídricos - Lei nº 9.433/97 e leis estaduais, é um tema importante para a indústria de alimentos, uma vez que pode alterar o perfil dos custos de produção de bens alimentícios. Assim, este artigo objetivou estimar os incrementos de preço provenientes da cobrança pelo uso da água bruta em uma indústria de laticínios e avaliar o potencial benefício dessa arrecadação, comparando-a com alguns investimentos previstos em planos de bacias hidrográficas. Para tal, foi utilizado um estudo de caso de uma indústria de laticínios com produção de 1 t/d de queijo mussarela, no Estado de Minas Gerais. Os resultados indicaram que o valor da cobrança pelo uso da água bruta entre as bacias hidrográficas com cobrança vigente pode variar em até 131%. O incremento de preço obtido pela cobrança de uso da água bruta foi baixo (0,04-0,09% dos custos de produção), indicando que este pode ser absorvido pelas indústrias. Por outro lado, os valores arrecadados pelas bacias podem ser decisivos para a efetivação de diversas ações voltadas para a melhoria da quantidade e da qualidade da água, beneficiando as próprias indústrias. Nos modelos de cobrança vigentes, no Estado de Minas Gerais, é possível reconhecer que a cobrança é uma iniciativa promissora para valorar economicamente a água. Porém, a cobrança ainda parece ser insuficiente para assegurar a racionalização do seu uso.

Several microalgae contain in excess of 50 % crude protein with amino acid profile comparable to that of fish meal. In addition, high polyunsaturated fatty acid contents encourage their use in animal feeding and nutrition, particularly in the formulation and processing of aquafeeds. This study aims at estimating the feasibility of Chlorella meal as feed ingredient for the feeding and nutrition of farmed tilapia based upon digestibility data. Juvenile tilapia were stocked in conical-bottomed tanks (200 L) with superficial, continuous water flow, and fed to apparent satiation in three daily meals with a reference diet and a test diet containing 30 % lyophilized Chlorella sorokiniana added of an inert marker. Feces were collected overnight by sedimentation in refrigerated, plastic containers coupled to the tanks and analyzed for determination of chemical composition and inert marker contents to estimate apparent digestibility coefficients (ADCs) of protein and energy of Chlorella meal; registered ADCs of Chlorella meal were 90.5 and 84.22, respectively. A pricing model considering the quantity of digestible nutrient was proposed based on ADCs of Chlorella and compared with the price of fishmeal (FM) and soybean meal (SBM). The indicative prices to elicit the use of Chlorella as a protein source rather than FM or SBM for the feed and nutrition of tilapia were 2.65 USD kg−1 and 0.66 USD kg−1, respectively.(AU)

BACKGROUND AND AIMS: Previous research indicates that minimum alcohol pricing (MAP) is associated negatively with alcohol-attributable (AA) hospitalizations. Modeling studies predict that this association will be stronger for people on lower incomes. The objective of this study was to test whether the association between MAP and AA hospitalizations is greater in low-income regions. DESIGN: Cross-sectional versus time-series analysis using multivariate multi-level effect models. SETTING: All 89 Local Health Areas in British Columbia (BC), Canada, 2002-13 (48 quarters). PARTICIPANTS: BC population. MEASUREMENTS: Quarterly rates of AA hospital admissions, mean consumer price index-adjusted minimum dollars per standard alcoholic drink and socio-demographic covariates. FINDINGS: Family income was related inversely to the effect of minimum prices on rates of some types of AA morbidity. A 1% price increase was associated with reductions of 3.547% [95% confidence interval (CI) = -5.719, -1.377; P < 0.01] in low family-income regions and 1.64% (95% CI = -2.765, -0.519; P < 0.01) across all income regions for 100% acute AA hospital admissions. Delayed (lagged) effects on chronic AA morbidity were found 2-3 years after minimum price increases for low income regions and all regions combined; a 1% increase in minimum price was associated with reductions of 2.242% (95% CI = -4.097, -0.388; P < 0.05) for 100% chronic AA and 2.474% (95% CI = -3.937, -1.011; P < 0.01) for partially chronic AA admissions for low-income regions. CONCLUSION: In Canada, minimum price increases for alcohol are associated with reductions in alcohol attributable hospitalizations, especially for populations with lower income, both for immediate effects on acute hospitalizations and delayed effects on chronic hospitalizations.

The current pricing process of raw milk in Brazil discourages producers from improving milk composition, which affects both yield and quality of dairy products. Furthermore, small and medium-sized dairies face great difficulties when it comes to planning production. Thus, a linear programming model was developed to price the raw milk and determine the optimal mix (combination of quantities) of dairy products that maximizes total contribution margin (TCM) under daily scenarios of high (January) and low (July) raw milk supplies (summer and winter, respectively) by comparing optimal solutions with actual results. The TCM of optimal and actual mixes were higher in January due to the greater availability of raw material. Packaging was a limiting factor in the production of cheese in optimal mixes. The relationship between unit contribution margin (UCM) and the required amount of raw materials per product unit and resource availability is crucial to defining the mix of dairy products and TCM of the dairy. Casein and raw milk volume showed shadow prices. Under both scenarios, the calculated prices of raw milk were higher than the prices charged by the dairy and were higher in January. The proposed model remunerates the producers based on the quantity and quality of raw milk. The dairy can maximize its TCM by better planning its mix of products with the use of linear programming.

ANTECEDENTES Y OBJETIVO La decisión de suscribir el acuerdo internacional Trans Pacific Partnership (TPP) promovido por EEUU, involucra el trabajo conjunto de diversos sectores del Estado. En ese sentido, este acuerdo tendría ciertas implicancias para el sector salud y, específicamente, para el mercado de fármacos en Chile. El TPP traería consigo cambios en la protección de información no divulgada, nuevos indicaciones clínicas y usos descubiertos, lo que impactaría fuertemente en el mercado de productos de síntesis biológica. En este contexto, el Departamento de Políticas Farmacéuticas solicita esta síntesis de evidencia con el objetivo de conocer si la introducción de competencia en el mercado de medicamentos generaría una reducción en el precio que los usuarios pagarían por estos productos. METODOLOGÍA Se formuló una estrategia de búsqueda para ser utilizada en las bases de datos PubMed, Cochrane Library, PDQ y Health System Evidence el objetivo de identificar revisiones sistemáticas del tema. Al no encontrar, se seleccionaron estudios primarios realizados en los últimos 5 años que abordaran la pregunta definida. No se incluyeron artículos que no abordaran directamente la intervención definida, tales como intervenciones para regular precios (precio de referencia, precio mínimo, reembolso máximo), drogas falsas, estudios que no incluyeran el precio o el gasto como resultado. RESULTADOS El resumen no utiliza revisiones sistemáticas -Los estudios considerados en esta síntesis rápida muestran que el ingreso de competencia al mercado de medicamentos reduce el precio promedio de venta. -El efecto se debe a la entrada de nuevos productos, el aumento de la participación de mercado de los competidores (en ventas) y el número de competidores en un mercado particular. -Dada su naturaleza más compleja, los medicamentos biosimilares necesitan establecer mecanismos costosos de bioequivalencia, lo que constituiría barreras de ingreso al mercado. -Producto de una escasa competencia en el mercado, se podrían generar pseudogenéricos, los cuales generarían un efecto paradójico (alza en los precios), al capturar gran participación de mercado o realizar altas inversiones en publicidad.
