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.

RESUMO

BACKGROUND: Across time, geographies and country income levels, smoking prevalence is highest among people with lower incomes. Smoking causes further impoverishment of those on the lower end of the income spectrum through expenditure on tobacco and greater risk of ill health. METHODS: This paper summarises the results of investment case equity analyses for 19 countries, presenting the effects of increased taxation on smoking prevalence, health and expenditures. We disaggregate the number of people who smoke, smoking-attributable mortality and cigarette expenditures using smoking prevalence data by income quintile. A uniform 30% increase in price was applied across countries. We estimated the effects of the price increase on smoking prevalence, mortality and cigarette expenditures. RESULTS: In all but one country (Bhutan), a one-time 30% increase in price would reduce smoking prevalence by the largest percent among the poorest 20% of the population. All income groups in all countries would spend more on cigarettes with a 30% increase in price. However, the poorest 20% would pay an average of 12% of the additional money spent. CONCLUSIONS: Our results confirm that health benefits from increases in price through taxation are pro-poor. Even in countries where smoking prevalence is higher among wealthier groups, increasing prices can still be pro-poor due to variable responsiveness to higher prices. The costs associated with higher smoking prevalence among the poor, together with often limited access to healthcare services and displaced spending on basic needs, result in health inequality and perpetuate the cycle of poverty.

RESUMO

This study investigates the impact of oil market uncertainty on the volatility of Chinese sector indexes. We utilize commonly used realized volatility of WTI and Brent oil price along with the CBOE crude oil volatility index (OVX) to embody the oil market uncertainty. Based on the sample span from Mar 16, 2011 to Dec 31, 2019, this study utilizes vector autoregression (VAR) model to derive the impacts of the three different uncertainty indicators on Chinese stock volatilities. The empirical results show, for all sectors, the impact of OVX on sectors volatilities are more economically and statistically significant than that of realized volatility of both WTI and Brent oil prices, especially after the Chinese refined oil pricing reform of March 27, 2013. That implies OVX is more informative than traditional WTI and Brent oil prices with respect to volatility spillover from oil market to Chinese stock market. This study could provide some important implications for the participants in Chinese stock market.

RESUMO

INTRODUCTION: While cigarette taxes are a vital tobacco control tool, their impact on cigarette tax revenue has been largely understudied in the extant literature. This study examines how the level of cigarette taxes affects the revenue generated from cigarettes in the United States over a thirty-year period. METHODS: We obtained the Tax Burden Data from the Centers for Disease Control and Prevention (1989-2019). Our dependent variables were gross cigarette tax revenue and per capita gross cigarette tax revenue, and our independent variable was state tax per pack. We used two-way fixed effects to estimate the relationship between state cigarette tax revenue and cigarette taxes, adjusting for state-level sociodemographic characteristics, state-fixed effects, and time trends. RESULTS: The study reveals that raising cigarette state tax by 10 % led to a 7.2 % to 7.5 % increase in cigarette tax revenue. We also found state and regional variation in taxes and revenue, with the Northeast region having the highest taxes per pack and tax revenues. In 2019, most states had low or moderate taxes per pack and tax revenues per capita, while a few states had high taxes per pack and tax revenues per capita. CONCLUSIONS: Our research demonstrates the positive impact of increased cigarette taxes on state tax revenue over three decades. Not only do higher taxes aid in tobacco control, but they also enhance state revenues that can be reinvested in state initiatives. Some states could potentially optimize their tax rates.

RESUMO

OBJECTIVES: Evidence suggests that cigarette costs significantly impact tobacco use, yet the effect of state-level cost variations on cigarette sales per capita in the US remains uncertain. This study investigates how state-level cigarette costs affect pack sales per capita consumption. STUDY DESIGN: This was an observational study of cigarette-pack sales per capita consumption in the United States. METHODS: We used the tobacco tax burden data (1989-2019) and a two-way fixed-effects model to analyse how cigarette costs affect consumption. Our predictor variables were average cost per pack, state tax per pack, and combined federal and state tax as a percentage of the retail price. Additionally, we compared the percentage change in state cigarette taxes per pack for each state in five-year intervals, adjusting for inflation. RESULTS: Regression analysis revealed that a 10% increase in the average cost per pack was related to a 9.59% decrease in per capita cigarette consumption (ß_average cost = -0.959, P < 0.001). Similarly, a rise in state tax per pack and a higher tax as a proportion of the retail price per pack were related to a decline in consumption (ß_ state tax = -0.176, P < 0.001), (ß_retail price = -0.323, P < 0.001). States that raised cigarette taxes beyond the rate of inflation had a higher reduction in cigarette per capita sales than those maintaining stable tax rates. CONCLUSIONS: Some states have not raised their cigarette taxes sufficiently to account for inflation. It appears that cigarette costs have significantly reduced cigarette consumption in the US.

RESUMO

BACKGROUND: Albania has one of the highest smoking prevalence in Europe especially among the youth. There is a lack of evidence in Albania, as well as in most of Eastern Europe and middle-income countries, regarding the effect of price on smoking experimentation. OBJECTIVE: The study aims to assess the effect of price and tobacco control policies on youth smoking experimentation in Albania. METHODS: We used microdata from the Global Youth Tobacco Survey in Albania for 2004, 2009, 2015 and 2020. We constructed a pseudo-longitudinal dataset and estimated a split-population model to assess the hazard of smoking experimentation. RESULTS: Price is a significant predictor of smoking experimentation among teenagers in Albania for both males and females (p<0.001). Being male increases the odds for smoking experimentation by more than 50% as compared with females (p<0.001), whereas females appear to be more price sensitive. Peer and parent smoking are also important determinants for smoking experimentation. Introducing penalties for smokers and legal entities violating smoke-free policies implemented in 2014 is also associated with a lower hazard of smoking experimentation. CONCLUSION: Price is a significant predictor of smoking experimentation among teenagers in Albania for both males and females. A combination of increasing taxes and strengthening the rule of law to control tobacco use in public spaces, in addition to public awareness campaigns targeting both youth and smoking parents, could help to significantly reduce the probability of smoking experimentation.

RESUMO

BACKGROUND: Despite thousands of licensed cannabis retail stores operating across Canada, there remains a significant illicit cannabis market. Some cannabis users continue to buy cannabis from dealers, illicit stores, and/or illicit online retailers. METHODS: Data are from the 2021 British Columbia Cannabis Use Survey. Respondents (n = 8473) were 19 years or older, lived in British Columbia at the time of the survey, and reported using cannabis in the past 12 months. RESULTS: Buying cannabis from all types of illicit sources was more common among younger cannabis users, those who use cannabis more frequently and started using cannabis before the age of 17 (vs. 19 or older), and among those who co-use cannabis with other drugs. Specifically, buying cannabis from a dealer was more common among men, those with lower educational attainment, and those who seek the lowest prices when buying cannabis. In contrast, those using cannabis for medical (vs. non-medical) purposes were more likely to report getting cannabis from illicit retail stores, while buying cannabis from illicit websites was more common among people who use edible cannabis products. CONCLUSION: Consistent with other studies, younger and more frequent cannabis users were more likely to report buying cannabis from illicit sources. However, these findings suggest there is significant heterogeneity among those who buy cannabis from different types of illicit sources, which should be carefully considered when developing policies and strategies aimed at encouraging consumers to transition to legal sources.

RESUMO

Vietnam is one of countries with the highest number of smokers in the world and the high smoking prevalence among men in the region. Although the real cigarette prices increased by around 4% during the 2010-2015 period, the prevalence of daily cigarette smoking among men decreased slightly from 31.3% to 30.7% during this period. This raises the question of whether cigarette consumption is sensitive to price. In this study, we estimated the effect of cigarette prices on smoking participation and tobacco expenditure in Vietnam. We found that a one-percent increase in the real cigarette price reduced the probability of cigarette smoking among males by 0.08 percentage points (95% CI from -0.06 to -0.10), equivalent to the price elasticity of the smoking prevalence at -0.26 (95% CI from -0.16% to -0.33%). Using this estimate, we predict that if the cigarette price is increased by 10%, the daily cigarette smoking prevalence among men would decrease from 30.7% to 29.9% and the number of male smokers would decline by around 270 thousand. Higher cigarette prices also reduced per capita tobacco expenditure of households. A one-percent increase in the cigarette price decreased per capita expenditure on tobacco consumption expenditure of households by 0.43 percent (the 95% CI from -0.029 to 0.822). This finding suggests that raising tobacco taxes and prices can be an effective measure to reduce tobacco use.

RESUMO

SUMMARY: The progress of biotechnology, medical instruments, and applied sciences contributes to a rapidly expanding space for the advancement of the medical field. Surgeons experience first-hand the limitations of current medical devices and thus have unique insight into problems that could be solved with new products. The process of turning an idea into a product capable of success in the marketplace, however, is often unfamiliar to surgeons. The authors seek to illuminate this process and provide an ordered list of tasks that can make bringing ideas to market more achievable for surgeons. The first step in this process is the generation and protection of a new idea. Next, the process of making an idea into a product is outlined. This phase involves team assembly, business planning, and product development. Market research and valuation are key to understanding how a product can be applied in the market, and meticulous research during this phase allows for informed decision-making that will help secure funding down the road. Finally, various options for financing are discussed and compared to help surgeon-entrepreneurs find an option that best fits their project, and steps to maximize leverage are described. The development of new products can be a complicated process for surgeons. Organized into four phases, with ordered instructional steps to advance through each phase, the process of bringing an idea to the market is clarified. Facilitating this process will possibly contribute to the continual improvement of medical and surgical abilities through the introduction of new devices and technologies.

RESUMO

The availability, purchase and consumption of foods high in fat, sugars and salt and low in fibre are linked to the high health and economic burden of noncommunicable diseases, including cancer, in Europe. Therefore, assessing the quality of the food offer is key as feedback to decision makers, as well as to identify good practices and areas of the food supply still requiring urgent action. We combined detailed market share and sales data with nutrition composition data to evaluate the nutritional quality of 14 packaged food and soft drinks categories sold across 22 European countries over the 2015-2018 period. Our analysis shows great variability of the nutritional composition within and among packaged food and soft drinks categories across European countries. Our estimates of the market-share weighted mean, a measure that integrates possible changes in nutrient content with the amount of a product sold to consumers, as well as daily per capita nutrient sale estimates, suggest a small but statistically significant progress in certain food categories only. Overall, the amounts of sugars, saturated fat, salt and fibre being sold to European citizens through these products is not improving to an extent to meet public health objectives.

RESUMO

Generally, research and studies about commodities focus on price trends, analysis in terms of international competitiveness, market position structure, rate of net exports, market share, and concentration index. This paper has developed an analysis of the most influential agricultural commodities traded from Colombia to European Union, which are bananas, coffee, and palm oil. Analyzing the economic and commercial effects in two traditional agricultural commodities from Colombia (bananas and coffee) with the rise of palm oil as a commodity in the trade relation with its partner; the European Union. The structure draws from the overview of general aspects and the behavior of Colombian foreign trade, as diversification of export products and trade partners, to focus on the characteristics of the trade relationship between the European Union and Colombia. The aim is analyze the proportional relation between bananas, coffee, and palm oil exported to the EU, according to three indicators, the volume of production, exports share, and trade value, from 2008 until 2019, identifying the trends before and after the implementation of the free trade agreement. Finally, with the coefficient correlation, determine the agricultural commodity that has the strongest and positive relationship with the total agricultural exports value from Colombia to the European Union.

RESUMO

Evidence for effective government policies to reduce exposure to alcohol's carcinogenic and hepatoxic effects has strengthened in recent decades. Policies with the strongest evidence involve reducing the affordability, availability and cultural acceptability of alcohol. However, policies that reduce population consumption compete with powerful commercial vested interests. This paper draws on the Canadian Alcohol Policy Evaluation (CAPE), a formal assessment of effective government action on alcohol across Canadian jurisdictions. It also draws on alcohol policy case studies elsewhere involving attempts to introduce minimum unit pricing and cancer warning labels on alcohol containers. Canadian governments collectively received a failing grade (F) for alcohol policy implementation during the most recent CAPE assessment in 2017. However, had the best practices observed in any one jurisdiction been implemented consistently, Canada would have received an A grade. Resistance to effective alcohol policies is due to (1) lack of public awareness of both need and effectiveness, (2) a lack of government regulatory mechanisms to implement effective policies, (3) alcohol industry lobbying, and (4) a failure from the public health community to promote specific and feasible actions as opposed to general principles, e.g., 'increased prices' or 'reduced affordability'. There is enormous untapped potential in most countries for the implementation of proven strategies to reduce alcohol-related harm. While alcohol policies have weakened in many countries during the COVID-19 pandemic, societies may now also be more accepting of public health-inspired policies with proven effectiveness and potential economic benefits.

RESUMO

Drug importation is a policy proposal to help alleviate rising pharmaceutical prices. Restrictions on drug importation stem from the Federal Food, Drug, and Cosmetic Act but authorization of importation can be made by the Health and Human Services (HHS) Secretary. During the Trump administration a number of states passed laws to develop a drug importation programs, however, none have been authorized by HHS. Limitations of these importation programs include sole reliance on Canada, exclusion of high-cost drugs like biologics, and persistent legal hazard of the Personal Importation Program. Potential revisions to current law include expansion of countries approved for importation, inclusion of biologics, and codifying protection for personal importation. Drug importation policies are not a panacea to address rising pharmaceutical prices but may blunt prices while more permanent solutions are pursued.

RESUMO

PURPOSE: The purpose of this study was to evaluate trends in Medicare reimbursement for common vascular procedures over the last decade. To enrich the context of this analysis, vascular procedure reimbursement is directly compared to inflation-adjusted changes in other surgical specialties. METHODS: The Centers for Medicare & Medicaid Services Physician/Supplier Procedure Summary file was utilized to identify the 20 procedures most commonly performed by vascular surgeons from 2011-2021. A similar analysis was performed for orthopedic, general, and neurological surgeons. The Centers for Medicare & Medicaid Services Physician-Fee Schedule Look-Up Tool was queried for each procedure, and reimbursement data was extracted. All monetary data was adjusted for inflation to 2021 dollars utilizing the consumer price index. Average year-over-year and total percentage change in reimbursement were calculated based on adjusted data for included procedures. Comparisons to other specialty data were made with ANOVA. RESULTS: From 2011-2021, the average, unadjusted change in reimbursement for vascular procedures was -7.2%. Accounting for inflation, the average procedural reimbursement declined by 20.1%. The greatest decline was observed in phlebectomy of varicose veins (-50.6%). Open arteriovenous fistula revision was the only vascular procedure with an increase in inflation-adjusted reimbursement (+7.5%). Year-over-year, inflation-adjusted reimbursement for common vascular procedures decreased by 2.0% per year. Venous procedures experienced the largest decrease in average adjusted reimbursement (-42.4%), followed by endovascular (-20.1%) and open procedures (-13.9%). These changes were significantly different across procedural subgroups (P < 0.001). During the same period, the average adjusted change in reimbursement for the 20 most common procedures in orthopedic surgery, general surgery, and neurosurgery was -11.6% vs. -20.1% for vascular surgery (P = 0.004). CONCLUSION: Medicare reimbursement for common surgical procedures has declined over the last decade. While absolute reimbursement has remained relatively stable for several procedures, accounting for a decade of inflation demonstrates the true diminution of buying power for equivalent work. The most alarming observation is that vascular surgeons have faced a disproportionate decrease in inflation-adjusted reimbursement in comparison to other surgical specialists. Awareness of these trends is a crucial first step towards improved advocacy and efforts to ensure the "value" of vascular surgery does not continue to erode.

RESUMO

This paper studies the connectedness between oil price shocks and agricultural commodities. Our sample period ranges from January 2002 to July 2020, covering the three global crises; Global Financial Crisis, the European sovereign debt crisis and Covid-19 pandemic crisis. We employ Granger causality tests, and the static and dynamic connectedness spillover index methodology. We find that the shocks in oil prices are Granger-caused mainly by price changes of grains, live cattle, and wheat, while supply shock granger causes variations mostly in grain prices. We find that, from the point of view of static connectedness, for both, price and volatility spillovers, the livestock is the largest transmitter, while the lean hogs are the major receiver. Our dynamic analysis evidences that connectedness increases during the financial crisis period. Our results are potentially useful for investors, portfolios managers and policy makers.
