Utilitarianism and Welfare

Utilitarianism is an ethical theory that holds that the best action is the one that produces the greatest amount of good for the greatest number of people.

The ultimate goal of economic policy according to utilitarianism is to maximize social welfare, which is the sum of the utilities of all individuals in a society.

Act utilitarianism evaluates the morality of an action based on its consequences, while rule utilitarianism evaluates the morality of an action based on the consequences of the rule that would allow the action.

The problem of interpersonal utility comparisons arises because there is no objective way to measure the utility of different individuals. This makes it difficult to determine which actions will produce the greatest amount of good for the greatest number of people.

The veil of ignorance is a thought experiment in which individuals are asked to make decisions about the distribution of resources without knowing their own personal characteristics, such as their race, gender, or socioeconomic status. This is intended to ensure that the decisions are made impartially and fairly.

Cardinal utility can be measured on a numerical scale, which allows for precise comparisons of the intensity of preferences. Ordinal utility, on the other hand, can only be ranked, which means that we can only say that one outcome is preferred to another, but we cannot say by how much.

The diminishing marginal utility of income means that the additional satisfaction that a person gets from each additional unit of income decreases as their income increases. This is because people tend to value the first few units of income more than the subsequent units.

A Pareto efficient allocation of resources is one in which it is impossible to make one person better off without making someone else worse off. This is also known as an optimal allocation of resources.

A Kaldor-Hicks efficient allocation of resources is one in which it is possible to make one person better off without making anyone else worse off. This is a weaker condition than Pareto efficiency, which requires that no one be made worse off.

The compensation principle is a principle of distributive justice that holds that those who benefit from a policy should compensate those who are harmed by the policy. This is intended to ensure that the benefits of the policy are shared fairly among all members of society.

Positive economics is the study of economic phenomena as they are, while normative economics is the study of economic phenomena as they should be. Positive economics is based on facts and data, while normative economics is based on values and preferences.

The economic theory of justice is the study of how resources should be distributed among members of a society. There are many different theories of justice, but one of the most common is the theory of equality, which holds that resources should be distributed equally among all members of society.

The Rawlsian difference principle is a principle of distributive justice that holds that social and economic inequalities should be arranged so that they are to the greatest benefit of the least advantaged members of society. This principle is based on the idea that all members of society have a right to a certain minimum level of well-being.

The Nozickian entitlement theory of justice is a theory of distributive justice that holds that people are entitled to the resources that they have acquired through just means. This theory is based on the idea that people have a right to their own property and that this right cannot be violated by the government or by other individuals.
