RESUMO

Background: Overwhelming evidence suggests that increasing alcohol taxes is an effective strategy for curbing alcohol consumption. However, research on the effects of such strategies in low- and middle-income nations is limited.Objective: The aim is to explore the temporal effect of alcohol tax policy in China.Methods: We employ interrupted time series analysis to investigate the temporal effects of tax policy changes on alcohol consumption and related consequences in Mainland China from 1961 to 2019. The study population, the total population of mainland region of China, aged more than 15 years.Results: The results show that the volume tax policy, which was announced in 2000 and implemented in 2001, led to an immediate reduction in the alcohol consumption (coefficient = -0.429, p < .001). Following the implementation of higher alcohol taxes in 1998 and 2001, the prevalence of alcohol use disorders (AUDs) and related years lived with disability (YLDs) gradually decreased. The relaxation of tax policy in 2006 led to a significant increase in alcohol consumption, both immediately (coefficient = 0.406, p < .001) and in the middle term (coefficient = 0.495, p < .001), as well as contribute to an immediate or medium term significant increase in the prevalence of AUDs (coefficient = 0.038, p = .010; coefficient = 0.032, p < .001) and YLDs (coefficient = 4.363, p = .001; coefficient = 4.226, p < .001).Conclusion: This study demonstrates that changes in alcohol consumption and related consequences (increase or decrease) have followed corresponding changes in alcohol tax policies (easing or tightening), indicating that increasing alcohol taxes can be an effective strategy in China for controlling alcohol consumption and related harms.

RESUMO

This article discusses the challenges and potential policy choices for levying progressive taxes and taxing the rich in Latin America, a region known for its high-income inequality, limited tax-collection capacity, and low share of taxes collected from personal income and wealth. Factors such as high exemption thresholds, low top marginal tax rates, and limited administrative capacity undermine the redistributive ability and revenue collection of the tax systems in the region. Moreover, the income composition for the top percentiles largely comes from capital, and the effective tax rates they face are often low due to the preferential treatment of capital income and wealth. After discussing the evidence of how the rich in Latin America respond to progressive taxes on income and wealth and changes in enforcement policy, we provide some insights on potential policy choices to tax them effectively. These may include broadening the income tax base by lowering the number of exempt and non-taxable income items and the statutory exemption thresholds, reevaluating preferential tax rates on capital income, monitoring foreign income, addressing the abuse of tax treatment by business earners, and enhancing tax administration capacity. Additionally, wealth taxes may complement the tax system with updates to property registers and scrutiny of foreign assets.

RESUMO

We examine the effectiveness of different fiscal policies in the Federation of Bosnia and Herzegovina (FBiH). For this purpose, we use a structural macroeconomic model for the FBiH. In this model, GDP in the Federation is influenced by world demand and by domestic demand in the Federation. Domestic demand comprises consumption of private households, public consumption, and gross fixed capital formation. Employment depends positively on GDP and negatively on the tax wedge, i.e., the net wage plus social security contribution rates (including the unemployment insurance), and the personal income tax rate in the Federation. The latter allows the analysis of the impact of changes in social security contribution rates or in the income tax rate in the Federation of Bosnia and Herzegovina. The following Federation-specific policy instruments are implemented in the model for the FBiH: Pension funds contribution rate in FBiH; contribution rate for health insurance in FBiH; contribution rate for the unemployment insurance in FBiH; benefits from social security; direct tax rates (income tax rate, corporate tax rate); public consumption in FBiH. Our results show that policy measures that reduce the tax wedge on labour income are highly effective in stimulating employment. Due to the large elasticity of imports with respect to demand, pure demand-side measures have little impact on real variables, indicating that a small open economy like the Federation of Bosnia and Herzegovina has only little scope for influencing macroeconomic developments with pure demand management policies. Our results confirm earlier theoretical and empirical studies showing that the labour market can best be influenced positively by reducing the tax wedge. The multipliers of income tax reductions are larger and oscillate more than the effects of the other fiscal policy measures.

RESUMO

In 2016, the Surgeon General used longitudinal cohort studies to conclude that youth e-cigarette use is strongly associated with cigarette use. We re-evaluate data from the period of time before the writing of the Surgeon General report, using quasi-experimental methods, and reach the opposite conclusion. We study contemporaneous and intertemporal effects of e-cigarette and cigarette price and tax changes. Our price variation comes from 35,000 retailers participating in the Nielsen Retail Scanner data system. We match price and tax variation to survey data on current use of e-cigarettes and cigarettes for over 94,000 students between grades 6 and 12 in the National Youth Tobacco Survey (NYTS) for years 2011-2015. We find evidence that e-cigarettes and cigarettes are same-period economic substitutes. Coefficient estimates (while imprecisely estimated) also suggest potentially large positive effects of past e-cigarette prices on current cigarette use, indicating intertemporal economic substitution. Our findings raise doubts about the conclusion of government-sponsored reports that e-cigarettes and cigarettes are strongly positively associated. We recommend revisiting and possibly amending this conclusion.

RESUMO

Family- and neighborhood-level poverty are associated with youth violence. Economic policies may address this risk factor by reducing parental stress and increasing opportunities. The federal Earned Income Tax Credit (EITC) is the largest cash transfer program in the US providing support to low-income working families. Many states have additional EITCs that vary in structure and generosity. To estimate the association between state EITC and youth violence, we conducted a repeated cross-sectional analysis using the variation in state EITC generosity over time by state and self-reported data in the Youth Risk Behavior Surveillance System (YRBSS) from 2005 to 2019. We estimated the association for all youth and then stratified by sex and race and ethnicity. A 10-percentage point greater state EITC was significantly associated with 3.8% lower prevalence of physical fighting among youth, overall (PR: 0.96; 95% CI 0.94-0.99), and for male students, 149 fewer (95% CI: -243, -55) students per 10,000 experiencing physical fighting. A 10-percentage point greater state EITC was significantly associated with 118 fewer (95% CI: -184, -52) White students per 10,000 experiencing physical fighting in the past 12 months while reductions among Black students (75 fewer; 95% CI: -176, 26) and Hispanic/Latino students (14 fewer; 95% CI: -93, 65) were not statistically significant. State EITC generosity was not significantly associated with measures of violence at school. Economic policies that increase financial security and provide financial resources may reduce the burden of youth violence; further attention to their differential benefits among specific population subgroups is warranted.

RESUMO

In 2014, the Navajo Nation Healthy Diné Nation Act (HDNA) was enacted and permanently approved in 2020; HDNA places a 2% surtax on unhealthy foods and beverages, while other 2014 legislation exempted healthy food items from the 6% regular sales tax. Little is known about Navajo Nation store manager/owner perspectives toward the HDNA and how best to support stores to implement the legislation. Purposive sampling was used to ensure a balanced sample of correct HDNA implementers, incorrect HDNA implementers, and stores which made healthy store changes over the past 6 years. Three community-based interviewers collected surveys by phone or in-person. Frequency of closed-ended questions was quantified, and open-ended responses were coded using thematic analysis. Of 29 identified sample stores, 20 were interviewed to reach saturation. Eleven of 20 stores made changes improving their healthy food environments. Barriers included lack of equipment (6/20) and low consumer demand (5/20). Facilitators included consumer awareness and increased produce supply options (5/20). Sixteen of 20 stores supported HDNA continuation. Facilitators to HDNA implementation included orientation and informational materials (6/20) and promotion of tax-free items (5/20). Barriers included confusion about the tax (6/20) and tax exemption (5/20). Suggestions for support included printed materials (6/20) and store training (5/20). HDNA benefits included greater awareness of healthy choices among staff (7/20) and customer-community members (2/20). Most managers and owners expressed receiving support for healthy store changes and HDNA, but also identified a need for added resources and support. Findings inform legislative action to promote timely and appropriate uptake of HDNA, and support equitable, healthy food systems.

RESUMO

This paper is concerned with cross-dependencies between endogenous market structure and tax policy. We extend the Mirrlees (Rev Econ Stud 38:175-208, 1971) model of income taxation with a monopolistic competition framework with general additively separable consumer preferences. We show that quantity and variety distortions resulting from the market structure require adjustments to income tax policy, which also needs to be complemented with commodity or firm taxation to achieve the constrained social optimum. We calibrate the model and find that in policy design the failure to account for the market structure results in a welfare loss of 1.77%. Motivated by practical cases, we study a policy regime that is solely based on income taxation. We show that departures from the social optimum can be compensated by lower and less regressive income taxes and a smaller government compared to the regime with income and commodity taxes. We also examine the role of consumer preferences for policy outcomes and show that it is substantially amplified by an endogenous market structure.

RESUMO

In this paper we analyse the effectiveness of demand- and supply-side fiscal policies in the small open economy of Slovenia. Simulating the SLOPOL10 model, an econometric model of the Slovenian economy, we analyse the effectiveness of various categories of public spending and taxes during the period 2020 to 2030, assuming that no crisis occurs. Our simulations show that those public spending measures that entail both demand- and supply-side effects are more effective at stimulating real GDP and increasing employment than pure demand-side measures. This is due to the fact that supply-side measures also increase potential and not only actual GDP. Measures which foster research and development and those which improve the education level of the labour force are particularly effective in this respect. Employment can also be stimulated effectively by cutting the income tax rate and the social security contribution rate, i.e. by reducing the tax wedge on labour income, which positively affects Slovenia's international competitiveness. Successful stabilisation policies should thus contain a supply-side component in addition to a demand-side component. We also provide a first simulation of potential effects of the Covid-19 crisis on the Slovenian economy, which is modelled as a combined demand and supply shock.

RESUMO

BACKGROUND: Consumption of sugar-sweetened beverages (SSBs) increases the risk of overweight and obesity. Taxing SSBs could decrease daily energy consumption and body weight. This model-based study evaluated the impact of a 20% SSB-sales tax on overweight and obesity in the context of Germany. METHODS: The population aged 15-79 years was modelled. Taxation was assumed to affect energy consumption via demand elasticities, which affected weight and BMI. Model-based analysis was performed to estimate the tax impact on BMI in different age, gender and income groups. RESULTS: Implementing a 20% SSB tax reduced energy consumption mainly in younger age groups, males, and those with low income. Taxation decreased the mean BMI in younger groups, with the largest decrease in those aged 20-29 years, while effects in groups 60 years or above were minimal. In absolute terms, taxation was estimated to avoid 1,028,000 (-3% relative reduction) overweight individuals and 479,000 obese individuals (-4%). Overweight decreased the most in males aged 20-29 years (408,000 fewer cases /-22%), the same applied for obesity (204,000/-22%). CONCLUSIONS: An SSB tax could have significant impact on overweight and obesity, which could translate into substantial reductions of morbidity and mortality.

RESUMO

The majority of the UK population is either overweight or obese. Health economists, nutritionists and doctors are calling for the UK to follow the example of other European countries and introduce a tax on soft drinks as a result of the perception that high intakes contribute to diet-related disease. We use a demand model estimated with household-level data on beverage purchases in the UK to investigate the effects of a tax on soft drink consumption. The model is a Quadratic Almost Ideal Demand System, and censoring is handled by applying a double hurdle. Separate models are estimated for low, moderate and high consumers to allow for a differential impact on consumption between these groups. Applying different hypothetical tax rates, we conclude that understanding the nature of substitute/complement relationships is crucial in designing an effective policy as these relationships differ between consumers depending on their consumption level. The overall impact of a soft drink tax on calorie consumption is likely to be small.

RESUMO

Scholarship on international health law is currently pushing the boundaries while taking stock of achievements made over the past few decades. However despite the forward thinking approach of scholars working in the field of global health one area remains a stumbling block in the path to achieving the right to health universally: the financing of heath. This paper uses the book Global Health Law by Larry Gostin to reflect and take stock of the fiscal support provided to the right to health from both a global and an African perspective. It then sets out the key fiscal challenges facing global and African health and proposes an innovative solution for consideration: use of the domestic principles of tax to design the global health financing system.

RESUMO

Violent injury varies widely across England and Wales as does the price of alcohol. While the links between alcohol consumption and violence are well established in the medical and epidemiological literature, a causal link is questionable. This paper cuts through the causative argument by reporting a link between the general price of alcohol and violence-related injury across the economic regions of England and Wales. It examines the influence of the real price of alcohol and identifies an 'April effect' that coincides with the annual uprating of alcohol prices for excise duties, on violence-related injuries recorded at Emergency Department attendance. The data are monthly frequency of violent injury rates covering the period 2005-2014 across the economic regions. The principal finding is that a one-way relationship between the real price of alcohol and violent injury is established, and tax policy can be used to reduce the incidence of violent injury and the associated health costs.

RESUMO

Background: The Sugar-Sweetened Beverage (SSB) industry consciously and subconsciously influences consumers to buy its products. Countering unhealthy messaging and behaviour could be tackled through the SSB levy and allocation of revenue toward healthy lifestyle programs. Given the limited information in the UAE on demographic and consumer knowledge and beliefs and allocation of SSB levy, we conducted a study to explore this further. The study objectives were to a) explore the association between demographic factors (nationality, income and education) with knowledge and beliefs for SSB and b) explore participants' views on allocating SSB levy toward healthy lifestyle programs. Methods: A cross-sectional study of adults in the United Arab Emirates. Results: The findings suggest knowledge was high for Sugar-Sweetened Beverages (SSB), obesity, and diabetes (1,231, 96.1%), and there was a high awareness of SSB tax (1,066, 83.2%). Knowledge and beliefs about Sugar-Sweetened Beverages were statistically significant for two demographic factors. There was support for the tax revenue to be spent on government programs and greater support for spending to be directed toward specific healthy lifestyle programs such as school health programmes (514, 39.8%), children's diet and nutrition programmes (497, 38.5%), physical activity programmes (480, 37.2%), among others. Conclusions: The findings shed light on the influence demographic factors have on knowledge and beliefs, public health gaps and potential areas for SSB levy expenditure. Further research is needed to understand how best to implement healthy lifestyle programs within the community to optimise coverage, cost-effectiveness, and health outcomes.

RESUMO

The carbon tax, a pivotal policy instrument in tackling climate change, holds the potential to significantly influence the development of society. To comprehensively analyse the effectiveness of the policy on carbon taxation and explore its possible optimisation path, this study utilizes system dynamics theory to establish a simulation model. A detailed analysis and evaluation of this policy is then conducted from the perspectives of the economy, the environment, and health. To guarantee the precision of the simulation model, a new, comprehensive evaluation method is proposed, which can test the degree of fit of the relative trend and absolute data of the simulation model with reality. The findings reveal that, despite its negative economic implications, a carbon tax policy has positive ramifications for the environment, energy, health, industrial structure, and carbon intensity targets. Furthermore, the synergistic reinforcement effect of R&D and new energy support policies on carbon taxation surpasses the impact of any individual policy alone. Notably, the influence of auxiliary policies has a temporal difference on this policy. Based on these insights, the study concludes with practical policy recommendations.

RESUMO

Diabetes has reached epidemic levels in the United States (US). This review compared two nationwide diabetes prevention policies: the National Diabetes Prevention Program (DPP) and the Penny-per-Ounce Excise (POE) tax policy on sugar-sweetened beverages (SSBs) based on their efficiency and efficacy in reducing the number of new cases of diabetes in the US. The study made a recommendation for the implementation of one or both policies based on the comparison. The national DPP focuses on screening for prediabetes in overweight/obese individuals and having positive subjects participate in a potentially insured one-year weight loss program with CDC-approved coaches. The POE tax on SSBs on the other hand is based on taxing SSBs with the objective that it will reduce new cases of diabetes due to a lower consumption of these beverages, or a switch to healthier alternatives. Studies that predicted the impact of either policy at the national level were used to compare both policies. The incremental cost-effectiveness ratio (ICER) was calculated by dividing the difference in net costs saved by the difference in net effectiveness (diabetes cases prevented per year); thereby comparing both policies in terms of costs saved for each diabetes case prevented per year. Using only nationwide US predictions, it has been estimated that the POE tax on SSB will produce the most cost savings with a greater impact on reducing new cases of diabetes if implemented; therefore, this tax should be recommended, in addition to the already implemented DPP.

RESUMO

The verdict in the case of Skatteverket v. David Hedqvist (Kokott, Advocate General (2015) Opinion delivered on 16 July 2015, Case C-264/14. ECLI:EU:C:2015:498. Available via TandF Online. 10.1080/20488432.2015.1096631.) is crucial for understanding how the EU treats virtual currencies, such as Bitcoin, in terms of Value-added Tax (VAT). This case involved the Swedish citizen David Hedqist who was seeking clarity from the Swedish Tax Authority Skatteverket on exchanging money for Bitcoins. The case set a precedent exempting such services from VAT under the EU's VAT Directive (Council Directive 2006/112/EC (2006) On the common system of value added tax. OJ L347. Available via EUR-Lex. https://eur-lex.europa.eu/legal-content/EN/ALL/?uri=CELEX:32006L0112. Accessed 3 January 2024.). Specifically, Article 135(1)(e) of the EU's VAT Directive excludes those transactions from VAT that include money-related transactions, that include deals or negotiations about different kinds of money, including cash and coins that are officially legal tender, i.e., used for buying things, except for collectable items like special coins or notes that people collect but do not use as a means of payment. Skatteverket (Kokott, Advocate General (2015) Opinion delivered on 16 July 2015, Case C-264/14. ECLI:EU:C:2015:498. Available via TandF Online. 10.1080/20488432.2015.1096631.) clarified that cash transactions are not subject to VAT, even though they are considered services for VAT purposes. Despite this clarity, the evolving landscape of digital assets' uniqueness, including Non-Fungible Tokens (Alawadhi KM, Alshamali N (2022) NFTs Emergence in Financial Markets and their Correlation with DeFis and Cryptocurrencies. Applied Economics and Finance 9:108. 10.11114/aef.v9i1.5444. Available at CORE. https://core.ac.uk/download/pdf/524752899.pdf. Accessed 3 January 2024.), continues to challenge VAT frameworks across member states. Using insights from the European Commission's Working Paper 1060, this article advocates for a unified approach tailored to digital and crypto services, addressing complexities in NFT taxation to reduce uncertainty and foster market cohesion. The findings highlight the importance of legislative changes and increased cross-border collaboration, as well as provide recommendations for policymakers and stakeholders in the digital finance and platform sector (European Commission (2024) Working Paper 1060. Available at: https://ec.europa.eu/info/publications/working-paper-1060_en. Accessed 3 March 2024.). By proposing strategic harmonisation of VAT enforcement, the research helps to improve tax compliance and support long-term growth in the EU's digital market (Cappai M (2023) The role of private and public regulation in the case study of crypto-assets: The Italian move towards participatory regulation.

RESUMO

Despite considerable academic and policy interest in the taxation of sugar-sweetened beverages (SSBs), its extra-health implications remain largely unexplored. We investigated the impact of an SSB tax on school absenteeism due to improved dental health, in a framework that accounted for the distribution of the benefit. We designed a quantitative, decision-analytic model that synthesised existing evidence in the areas of dental epidemiology, public health and economics, and simulated causal mechanisms that lead to changes in school attendance in Australian children and adolescents aged 6-17, in a tax vs no tax scenarios. Introducing a 20% sales tax on SSBs would result in a 0.73% (95% confidence interval: 0.38; 1.10), or 4684 (2412; 7071) days per year nationwide, reduction in school absences attributable to dental health reasons. While positive impacts would be seen across the board, the distribution of benefit was favourable towards boys, older teens and those from lower socio-economic status. Our study highlights the need for, and the viability of, quantifying distributions of direct and indirect consequences of public health policy. Despite modest effect size, the equity profile of SSB tax, the long-lasting benefits of educational gains, and potential synergies with other interventions, make it an attractive option for policymakers to consider.

RESUMO

Waste electrical and electronic equipment is one of the essential pollutants with significant negative impacts on the environment and human health. In this study, a multi-period mixed-integer linear programming model is developed to design a closed loop supply network for the management of electrical and electronic equipment by explicitly considering the economic and environmental sustainability with a budget constraint. Different recycling options like refurbishing, disassembling, remanufacturing, and disposal centers are considered in the design of the network. The model minimizes the total costs of the network and the total carbon emission tax. The literature review shows that the introduced model is more comprehensive than the other existing models because it simultaneously determines the location of facilities, the capacity of facilities, type of manufacturing technologies, variety of vehicles, and the allocation and transportation of materials and products. The model was applied to a real-life case study in Iran and could provide a profit of IRR 245,509,165 M during the planning periods. The carbon tax policy with different echelons is applied to control the environmental impacts in which the carbon tax increases as carbon emissions increase. The results show a nearly linear relationship between the total costs of the network and the carbon tax. The carbon tax of equal to or more than 10,800 IRR/t CO2 can be a deterrent factor for the electrical and electronic equipment manufacturer in Iran to diminish emissions through investment in green technologies.

RESUMO

Global warming and e-waste pollution are two major environmental pollution issues that have attracted widespread attention. The government has adopted various measures to reduce carbon emissions from businesses and to make manufacturers responsible for recycling e-waste. In the face of external pressures, more and more companies are implementing sustainable closed-loop supply chain (CLSC) management to reduce environmental pollution and achieve sustainable development. Therefore, it is essential to study the operational decisions of CLSC enterprises. This paper considers a sustainable CLSC consisting of two competing manufacturers and a dominant retailer. The government imposes a carbon tax on the retailer, and two manufacturers collect used products directly from their customers. We separately examine whether implementing green marketing by the retailer and the collaboration between the two manufacturers can improve their profits. By building decentralized CLSC mathematical models and applying game theory methods, we obtain that green marketing can increase profits for all CLSC members and improve return rates. The collaboration may yield higher total profits for two manufacturers than a decentralized solution, while the retailer's profits may be lost under certain conditions. Finally, we perform several numerical analyses to find the relationship between unit carbon emission tax and social welfare and gain some managerial insights. The study gives key factors that CLSC companies should consider when making decisions to help them achieve sustainability and provides recommendations for the government to set a reasonable unit carbon tax.

RESUMO

Sugar-sweetened beverage (SSB) consumption is associated with obesity and independently associated with type 2 diabetes and cardiovascular disease. Not only is obesity a growing public health problem, but it is also most recently associated with increased risk of severe illness from COVID-19. Taxes on SSBs are a policy tool used to help curb SSB consumption and are currently implemented in 7 U.S. cities and more than 40 countries. On July 1, 2017, Oakland, California, implemented a 1-cent/ounce tax on SSBs with ≥25 kilocalories/12 ounces. This study estimated the impact of the Oakland tax on prices, volume sold, and cross-border shopping two-years post-tax relative to one-year pre-tax. Universal product code-level Nielsen retail scanner data on non-alcoholic beverage sales were analyzed using a difference-in-differences design with Sacramento, California, as the comparison site. Taxed beverage prices increased by 0.67 cents/ounce, on average, in Oakland relative to Sacramento, corresponding to 67% pass-through. Taxed beverage volume sold decreased by 18% in Oakland relative to Sacramento, with a larger decrease for family-size beverages (23%) relative to individual-size beverages (8%). There was a 9% increase in volume sold of taxed beverages in the two-mile border area surrounding Oakland relative to the Sacramento border area, driven by a 12% increase for family-size taxed beverages. After accounting for this cross-border shopping, there was a net decrease of 6% in taxed beverage volume sold in Oakland. There was no significant change in untaxed beverage volume sold in either Oakland or its border area relative to their respective comparison sites, suggesting there was no substitution to untaxed beverages and cross-border shopping may have been limited to taxed beverages. This two-year post-tax study of the Oakland SSB tax adds to the limited number of longer-term evaluations of local U.S. SSB taxes.
