An internality is the long-term benefit or cost to an individual that they do not consider when making the decision to consume a good or service. One way this is related to behavioral economics is by means of the concept of hyperbolic discounting, in which immediate consequences of a decision are disproportionately weighed compared to the future consequences. [1] A potential cause is lack of access to full information regarding the associated costs and benefits prior to consumption. This contrasts with traditional economic theory, which makes the assumption that individuals are rational decision makers who take all personal costs into account when paying for goods and services. [2]
One example of a positive internality is the long run effect of exercising, if these are not taken into account when deciding whether to exercise. Future benefits that an individual may not take into consideration include a diminished risk of heart disease and higher bone density. [1] A common example of a potential negative internality is the effect of smoking cigarettes on those who smoke. For the effect of secondhand smoke, see externality. Statistically, 80% of smokers want to quit, and 54% of people who are serious about quitting fail in a week or less. [3] This implies that they do not act in their long-term best interest due to short-term discomfort. This is also known as the self-control problem, an inability to control short-term consumption to optimize long-term consumption. Smokers also may inflict an internality on themselves due to a lack of information on the issue or myopia.
If the demand for cigarettes has a high price elasticity of demand, which evidence seems to suggest, the government can combat the negative internality by raising taxes. [3] It is important to note that elasticity might change based on location and knowledge about the harmful health effects of smoking. [4] In traditional economic theory, a tax diminishes the welfare of the poor because the tax burden shifts to low-income communities, as fewer can afford the good (cigarettes), and horizontal equity (economics) is distorted. However, behavioral economic theory suggests that the tax is not regressive if low-income communities have higher (healthcare) costs and more price sensitivity than individuals with higher incomes. [4] Taxes imposed to combat internalities are most effective when they target a specific good. A tax on junk food could apply to a large variety of goods that are widely consumed, and the cost of the tax might be perceived as more detrimental than beneficial for society. [5] Another concern with instituting this type of tax is its potential to be regressive, meaning it takes the most money from those with the least resources. For example, a tax on sugary-sweetened beverages corrects an internality, but it is also regressive, as it has been shown people with lower incomes spend more on sugary-sweetened beverages. [6] However, it has also been shown that people who consume the most sugary-sweetened beverages have the most lack of knowledge and thus the largest internalities, so the tax may end up not harming lower-income people but benefiting them the most. [7] A major issue with creating effective legislature against negative internalities is that the tax imposed should only reflect the cost that individuals do not factor into their consumption decisions. [8] The difficulty in measuring individual knowledge is an obstacle to developing new policies. Another point of concern is that the group benefitting from the tax, such as smokers who want to quit, must be sizable enough to offset any backlash from tobacco companies and lobbyists. [5]
In the following graphs, D' and S' are the demand and supply curves if producers and consumers take all external costs (EC) into consideration. The tax attempting to prevent the internality should be set equal to the difference between D and D' at the optimal quantity, which is the unmeasured internal cost (IC).
Increasing access to information about the costs of consuming a particular good, such as cigarettes, junk food, or sugar-sweetened beverages, is especially important. This allows people to know the costs of their actions and whether they choose to act on this knowledge is their rational decision. As a result of this, in cases where products or goods are not banned, increasing access to information may not necessarily be useful for individuals with a self-control problem.
A soft drink is a drink that usually contains water, a sweetener, and a natural and/or artificial flavoring. The sweetener may be a sugar, high-fructose corn syrup, fruit juice, a sugar substitute, or some combination of these. Soft drinks may also contain caffeine, colorings, preservatives, and/or other ingredients.
A tax is a compulsory financial charge or some other type of levy imposed on a taxpayer by a governmental organization in order to fund government spending and various public expenditures, and tax compliance refers to policy actions and individual behaviour aimed at ensuring that taxpayers are paying the right amount of tax at the right time and securing the correct tax allowances and tax reliefs. The first known taxation took place in Ancient Egypt around 3000–2800 BC. A failure to pay in a timely manner (non-compliance), along with evasion of or resistance to taxation, is punishable by law. Taxes consist of direct or indirect taxes and may be paid in money or as its labor equivalent.
Participatory economics, often abbreviated Parecon, is an economic system based on participatory decision making as the primary economic mechanism for allocation in society. In the system, the say in decision-making is proportional to the impact on a person or group of people. Participatory economics is a form of socialist decentralized planned economy involving the common ownership of the means of production. It is a proposed alternative to contemporary capitalism and centralized planning. This economic model is primarily associated with political theorist Michael Albert and economist Robin Hahnel, who describes participatory economics as an anarchist economic vision.
In economics, a public good is a good that is both non-excludable and non-rivalrous. For such goods, users cannot be barred from accessing or using them for failing to pay for them. Also, use by one person neither prevents access of other people nor does it reduce availability to others. Therefore, the good can be used simultaneously by more than one person. This is in contrast to a common good, such as wild fish stocks in the ocean, which is non-excludable but rivalrous to a certain degree. If too many fish were harvested, the stocks would deplete, limiting the access of fish for others. A public good must be valuable to more than one user, otherwise, the fact that it can be used simultaneously by more than one person would be economically irrelevant.
In economics, time preference is the current relative valuation placed on receiving a good or some cash at an earlier date compared with receiving it at a later date.
Consumption is the act of using resources to satisfy current needs and wants. It is seen in contrast to investing, which is spending for acquisition of future income. Consumption is a major concept in economics and is also studied in many other social sciences.
A sin tax is an excise tax specifically levied on certain goods deemed harmful to society and individuals, such as alcohol, tobacco, drugs, candies, soft drinks, fast foods, coffee, sugar, gambling, and pornography. In contrast to Pigovian taxes, which are to pay for the damage to society caused by these goods, sin taxes are used to increase the price in an effort to lower demand, or failing that, to increase and find new sources of revenue. Increasing a sin tax is often more popular than increasing other taxes. However, these taxes have often been criticized for burdening the poor and taxing the physically and mentally dependent.
Club goods are a type of good in economics, sometimes classified as a subtype of public goods that are excludable but non-rivalrous, at least until reaching a point where congestion occurs. Often these goods exhibit high excludability, but at the same time low rivalry in consumption. Thus, club goods have essentially zero marginal costs and are generally provided by what is commonly known as natural monopolies. Furthermore, club goods have artificial scarcity. Club theory is the area of economics that studies these goods. One of the most famous provisions was published by Buchanan in 1965 "An Economic Theory of Clubs," in which he addresses the question of how the size of the group influences the voluntary provision of a public good and more fundamentally provides a theoretical structure of communal or collective ownership-consumption arrangements.
An indirect tax is a tax that is levied upon goods and services before they reach the customer who ultimately pays the indirect tax as a part of market price of the good or service purchased. Alternatively, if the entity who pays taxes to the tax collecting authority does not suffer a corresponding reduction in income, i.e., impact and tax incidence are not on the same entity meaning that tax can be shifted or passed on, then the tax is indirect.
A consumption tax is a tax levied on consumption spending on goods and services. The tax base of such a tax is the money spent on consumption. Consumption taxes are usually indirect, such as a sales tax or a value-added tax. However, a consumption tax can also be structured as a form of direct, personal taxation, such as the Hall–Rabushka flat tax.
A tax incentive is an aspect of a government's taxation policy designed to incentivize or encourage a particular economic activity by reducing tax payments.
A fat tax is a tax or surcharge that is placed upon fattening food, beverages or on overweight individuals. It is considered an example of Pigovian taxation. A fat tax aims to discourage unhealthy diets and offset the economic costs of obesity.
Tax policy refers to the guidelines and principles established by a government for the imposition and collection of taxes. It encompasses both microeconomic and macroeconomic aspects, with the former focusing on issues of fairness and efficiency in tax collection, and the latter focusing on the overall quantity of taxes to be collected and its impact on economic activity. The tax framework of a country is considered a crucial instrument for influencing the country's economy.
Optimal tax theory or the theory of optimal taxation is the study of designing and implementing a tax that maximises a social welfare function subject to economic constraints. The social welfare function used is typically a function of individuals' utilities, most commonly some form of utilitarian function, so the tax system is chosen to maximise the aggregate of individual utilities. Tax revenue is required to fund the provision of public goods and other government services, as well as for redistribution from rich to poor individuals. However, most taxes distort individual behavior, because the activity that is taxed becomes relatively less desirable; for instance, taxes on labour income reduce the incentive to work. The optimization problem involves minimizing the distortions caused by taxation, while achieving desired levels of redistribution and revenue. Some taxes are thought to be less distorting, such as lump-sum taxes and Pigouvian taxes, where the market consumption of a good is inefficient, and a tax brings consumption closer to the efficient level.
An excise, or excise tax, is any duty on manufactured goods that is levied at the moment of manufacture rather than at sale. Excises are often associated with customs duties, which are levied on pre-existing goods when they cross a designated border in a specific direction; customs are levied on goods that become taxable items at the border, while excise is levied on goods that came into existence inland.
A sugary drink tax, soda tax, or sweetened beverage tax (SBT) is a tax or surcharge designed to reduce consumption of sweetened beverages. Drinks covered under a soda tax often include carbonated soft drinks, sports drinks and energy drinks. This policy intervention is an effort to decrease obesity and the health impacts related to being overweight, however the medical evidence supporting the benefits of a sugar tax on health is of very low certainty. The tax is a matter of public debate in many countries and beverage producers like Coca-Cola often oppose it. Advocates such as national medical associations and the World Health Organization promote the tax as an example of Pigovian taxation, aimed to discourage unhealthy diets and offset the growing economic costs of obesity.
A sweetened beverage is any beverage with added sugar. It has been described as "liquid candy". Consumption of sweetened beverages has been linked to weight gain, obesity, and associated health risks. According to the CDC, consumption of sweetened beverages is also associated with unhealthy behaviors like smoking, not getting enough sleep and exercise, and eating fast food often and not enough fruits regularly.

A meat tax is a tax levied on meat and/or other animal products to help cover the health and environmental costs that result from using animals for food. Livestock is known to significantly contribute to global warming, and to negatively impact global nitrogen cycles and biodiversity.
Sugar is heavily marketed both by sugar producers and the producers of sugary drinks and foods. Apart from direct marketing methods such as messaging on packaging, television ads, advergames, and product placement in setting like blogs, industry has worked to steer coverage of sugar-related health information in popular media, including news media and social media.
