Labour economics in the context of "Dialectical materialist"

A conurbation is a region consisting of a number of metropolises, cities, large towns, and other urban areas which, through population growth and physical expansion, have merged to form one continuous urban or industrially developed area. In most cases, a conurbation is a polycentric urbanised area in which transportation has developed to link areas. They create a single urban labour market or travel to work area.

Conurbations often emerged in coal-mining regions during the period of the Industrial Revolution.Patrick Geddes coined the term in his book Cities in Evolution (1915). He drew attention to the ability of the new technology at the time of electric power and motorised transport to allow cities to spread and agglomerate together, and gave as examples "Midlandton" in England, the Ruhr in Germany, Randstad in the Netherlands, and the Northeastern Seaboard in the United States.

The Reconstruction era was a period in US history that followed the American Civil War (1861–1865) and was dominated by the legal, social, and political challenges of the abolition of slavery and reintegration of the former Confederate States into the United States. Three amendments were added to the United States Constitution to grant citizenship and equal civil rights to the newly freed slaves. To circumvent these, former Confederate states imposed poll taxes and literacy tests and engaged in terrorism to intimidate and control African Americans and discourage or prevent them from voting.

Throughout the war, the Union was confronted with the issue of how to administer captured areas and handle slaves escaping to Union lines. The United States Army played a vital role in establishing a free labor economy in the South, protecting freedmen's rights, and creating educational and religious institutions. Despite its reluctance to interfere with slavery, Congress passed the Confiscation Acts to seize Confederates' slaves, providing a precedent for President Abraham Lincoln to issue the Emancipation Proclamation. Congress established a Freedmen's Bureau to provide much-needed food and shelter to the newly freed slaves. As it became clear the Union would win, Congress debated the process for readmission of seceded states. Radical and moderate Republicans disagreed over the nature of secession, conditions for readmission, and desirability of social reforms. Lincoln favored the "ten percent plan" and vetoed the Wade–Davis Bill, which proposed strict conditions for readmission. Lincoln was assassinated in 1865, just as fighting was drawing to a close. He was replaced by Andrew Johnson, who vetoed Radical Republican bills, pardoned Confederate leaders, and allowed Southern states to enact draconian Black Codes that restricted the rights of freedmen. His actions outraged many Northerners and stoked fears the Southern elite would regain power. Radical Republicans swept to power in the 1866 midterm elections, gaining majorities in both houses of Congress.

Wage labour (also wage labor in American English), usually referred to as paid work, paid employment, or paid labour, refers to the socioeconomic relationship between a worker and an employer in which the worker sells their labour power under a formal or informal employment contract. These transactions usually occur in a labour market where wages or salaries are market-determined.

In exchange for the money paid as wages (usual for short-term work-contracts) or salaries (in permanent employment contracts), the work product generally becomes the undifferentiated property of the employer. A wage labourer is a person whose primary means of income is from the selling of their labour in this way.

An informal economy (informal sector or grey economy) is the part of any economy that is neither taxed nor monitored by any form of government. Although the informal sector makes up a significant portion of the economies in developing countries, it is sometimes stigmatized as troublesome and unmanageable. However, the informal sector provides critical economic opportunities for the poor and has been expanding rapidly since the 1960s. Integrating the informal economy into the formal sector is an important policy challenge.

In many cases, unlike the formal economy, activities of the informal economy are not included in a country's gross national product (GNP) or gross domestic product (GDP). However, Italy has included estimates of informal activity in their GDP calculations since 1987, which swells their GDP by an estimated 18% and in 2014, a number of European countries formally changed their GDP calculations to include prostitution and narcotics sales in their official GDP statistics, in line with international accounting standards, prompting an increase between 3-7%. The informal sector can be described as a grey market in labour. Other concepts that can be characterized as informal sector can include the black market (shadow economy, underground economy), agorism, and System D. Associated idioms include "under the table", "off the books", and "working for cash".

Strike action, also called labor strike, labour strike in British English, or simply strike, is a work stoppage caused by the mass refusal of employees to work. A strike usually takes place in response to employee grievances. Strikes became common during the Industrial Revolution, when mass labor became important in factories and mines. As striking became a more common practice, governments were often pushed to act (either by private business or by union workers). When government intervention occurred, it was rarely neutral or amicable. Early strikes were often deemed unlawful conspiracies or anti-competitive cartel action and many were subject to massive legal repression by state police, federal military power, and federal courts. Many Western nations legalized striking under certain conditions in the late 19th and early 20th centuries.

Strikes are sometimes used to pressure governments to change policies. Occasionally, strikes destabilize the rule of a particular political party or ruler; in such cases, strikes are often part of a broader social movement taking the form of a campaign of civil resistance. Notable examples are the 1980 Gdańsk Shipyard and the 1981 Warning Strike led by Lech Wałęsa. These strikes were significant in the long campaign of civil resistance for political change in Poland, and were an important mobilizing effort that contributed to the fall of the Iron Curtain and the end of communist party rule in Eastern Europe. Another example is the general strike in Weimar Germany that followed the March 1920 Kapp Putsch. It was called by the Social Democratic Party (SPD) and received such broad support that it resulted in the collapse of the putsch.

In economics, the principle of absolute advantage is the ability of a party (an individual, or firm, or country) to produce a goods or service more efficiently than its competitors. The Scottish economist Adam Smith first described the principle of absolute advantage in the context of international trade in 1776, using labor as the only input. Since absolute advantage is determined by a simple comparison of labor productiveness, it is possible for a party to have no absolute advantage in anything.
