Monopolies in the context of "Oligopolies"

Progressivism is a left-leaning political philosophy and reform movement that seeks to advance the human condition through social reform. Adherents hold that progressivism has universal application and endeavor to spread this idea to human societies everywhere. Progressivism arose during the Age of Enlightenment out of the belief that civility in Europe was improving due to the application of new empirical knowledge.

In modern political discourse, progressivism is often associated with social liberalism, a left-leaning type of liberalism, and social democracy. Within economic progressivism, there is some ideological variety on the social liberal to social democrat continuum, as well as occasionally some variance on cultural issues; examples of this include some Christian democrat and conservative-leaning communitarian movements. While many ideologies can fall under the banner of progressivism, both the current and historical movement are characterized by a critique of unregulated capitalism, desiring a more active democratic government to take a role in safeguarding human rights, bringing about cultural development, and being a check-and-balance on corporate monopolies.

In theories of competition in economics, a barrier to entry, or an economic barrier to entry, is a fixed cost that must be incurred by a new entrant, regardless of production or sales activities, into a market that incumbents do not have or have not had to incur.Because barriers to entry protect incumbent firms and restrict competition in a market, they can contribute to distortionary prices and are therefore most important when discussing antitrust policy. Barriers to entry often cause or aid the existence of monopolies and oligopolies, or give companies market power.Barriers of entry also have an importance in industries. First of all it is important to identify that some exist naturally, such as brand loyalty.Governments can also create barriers to entry to meet consumer protection laws, protecting the public. In other cases it can also be due to inherent scarcity of public resources needed to enter a market.

Economic liberalism is a political and economic ideology that supports a market economy based on individualism and private property in the means of production. Adam Smith is considered one of the primary initial writers on economic liberalism, and his writing is generally regarded as representing the economic expression of 19th-century liberalism up until the Great Depression and rise of Keynesianism in the 20th century. Historically, economic liberalism arose in response to feudalism and mercantilism.

Economic liberalism is associated with markets and private ownership of capital assets. Economic liberals tend to oppose government intervention and protectionism in the market economy when it inhibits free trade and competition, but tend to support government intervention where it protects property rights, opens new markets or funds market growth, and resolves market failures. They also tend to oppose cartels, monopolies, financialization of the economy, rent-seeking behaviour and unproductive classes reliant on rent, assets or state-granted privileges. An economy that is managed according to these precepts may be described as a liberal economy or operating under liberal capitalism. Economic liberals commonly adhere to a political and economic philosophy that advocates a restrained fiscal policy and a balanced budget through measures such as low taxes, reduced government spending, and minimized government debt. Free trade, deregulation, tax cuts, privatization, labour market flexibility, and opposition to trade unions are also common positions.

Modern liberalism, often referred to simply as liberalism, is the dominant ideological variant of liberalism in the United States. It is most synonymous with the ideology of social liberalism, which is a variant of liberalism that moves beyond classical liberalism to account for poverty, seeking a balance between civil liberty and social equality via a social safety net. U.S. modern liberalism also takes inspiration from cultural liberalism and progressivism, and some (but not all) modern liberals explicitly identify with the contemporary U.S. progressive movement. Writing in 1993, American academic writer Ian Adams argued all major U.S. parties up to that point were "liberal and always have been. Essentially they espouse classical liberalism, that is a form of democratized Whig constitutionalism plus the free market. The point of difference comes with the influence of social liberalism."

Economically, modern liberalism accepts a role for government to protect against market failures, protect competition and prevent corporate monopolies, and supports labor rights. Its fiscal policy supports sufficient funding for a social safety net, while simultaneously promoting income-proportional tax reform policies to reduce deficits. It calls for active government involvement in other social and economic matters such as reducing economic inequality, expanding access to education and healthcare, and protection of the shared natural environment, in large part on the contention that advances in those areas create a thriving economy in the long run. Modern liberalism was formed in the 20th century in response to the Great Depression. Major examples of modern liberal policy programs include the New Deal, the Fair Deal, the New Frontier, the Great Society, the Affordable Care Act, and the Build Back Better Plan.

The Tiangong Kaiwu (天工開物), or The Exploitation of the Works of Nature was a Chinese encyclopedia compiled by Song Yingxing. It was published in May 1637 with funding provided by Song's patron Tu Shaokui. The Tiangong Kaiwu is an encyclopedia covering a wide range of technical issues, including the use of various gunpowder weapons. Copies of the book were very scarce in China during the Qing dynasty (1644–1911) (due to the government's establishment of monopolies over certain industries described in the book), but original copies of the book were preserved in Japan.
