Trade in the context of "Economic depression"

A civilization (also spelled civilisation in British English) is any complex society characterized by the development of the state, social stratification, urbanization, and symbolic systems of communication beyond signed or spoken languages (namely, writing systems).

Civilizations are organized around densely populated settlements, divided into more or less rigid hierarchical social classes of division of labour, often with a ruling elite and subordinate urban and rural populations, which engage in intensive agriculture, mining, small-scale manufacture and trade. Civilization concentrates power, extending human control over the rest of nature, including over other human beings. Civilizations are characterized by elaborate agriculture, architecture, infrastructure, technological advancement, currency, taxation, regulation, and specialization of labour.

Transport (in British English) or transportation (in American English) is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipelines, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations.

Transport infrastructure consists of fixed installations, including roads, railways, airways, waterways, canals, and pipelines, as well as terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fuel docks and fuel stations), and seaports. Terminals may be used both for the interchange of passengers and cargo and for maintenance.

Business is the practice of making one's living or making money by producing or buying and selling products (such as goods and services). It is also "any activity or enterprise entered into for profit."

A business entity is not necessarily separate from the owner and the creditors can hold the owner liable for debts the business has acquired except for limited liability company. The taxation system for businesses is different from that of the corporates. A business structure does not allow for corporate tax rates. The proprietor is personally taxed on all income from the business.

International trade is the exchange of capital, goods, and services across international borders or territories because there is a need or want of goods or services.

In most countries, such trade represents a significant share of gross domestic product (GDP). While international trade has existed throughout history (for example Uttarapatha, Silk Road, Amber Road, salt roads), its economic, social, and political importance has been on the rise in recent centuries.

Commerce is the organized system of activities, functions, procedures and institutions that directly or indirectly contribute to the smooth, unhindered exchange of goods, services, and other things of value—predominantly through transactional processes—at the right time, place, quantity, quality and price through various channels among the original producers and the final consumers within local, regional, national or international economies. The diversity in the distribution of natural resources, differences of human needs and wants, and division of labour along with comparative advantage are the principal factors that give rise to commercial exchanges.

Commerce consists of trade and aids to trade (i.e. auxiliary commercial services) taking place along the entire supply chain. Trade is the exchange of goods (including raw materials, intermediate and finished goods) and services between buyers and sellers in return for an agreed-upon price at traditional (or online) marketplaces. It is categorized into domestic trade, including retail and wholesale as well as local, regional, inter-regional and international/foreign trade (encompassing import, export and entrepôt/re-export trades). The exchange of currencies (in foreign exchange markets), commodities (in commodity markets/exchanges) and securities and derivatives (in stock exchanges and financial markets) in specialized exchange markets, typically operating under the domain of finance and investment, also falls under the umbrella of trade. On the other hand, auxiliary commercial activities (aids to trade) which can facilitate trade include commercial intermediaries, banking, credit financing and related services, transportation, packaging, warehousing, communication, advertising and insurance. Their purpose is to remove hindrances related to direct personal contact, payments, savings, funding, separation of place and time, product protection and preservation, knowledge and risk.

International law, also known as public international law and the law of nations, is the set of rules, norms, legal customs and standards that states and other actors feel an obligation to, and generally do, obey in their mutual relations. In international relations, actors are simply the individuals and collective entities, such as states, international organizations, and non-state groups, which can make behavioral choices, whether lawful or unlawful. Rules are formal, typically written expectations that outline required behavior, while norms are informal, often unwritten guidelines about appropriate behavior that are shaped by custom and social practice. It establishes norms for states across a broad range of domains, including war and diplomacy, economic relations, and human rights.

The term public international law embraces a wide variety legal regimes governing the conduct and relationships between states, between states and international organizations, and between entities and persons both natural and legal. Public international law defines the criteria for statehood, and legal theorists argue that it establishes states as the principal actors in the international legal system. (While the traditional view was that only states were subjects of international law, with the founding of the United Nations, that view expanded to include intergovernmental organizations. Contemporary conceptions of international law are much broader, and include the interactions such as the ones listed at the beginning of this paragraph.) Public International law also governs the outer bounds of permissible treatment of individuals by states with comprehensive international law regimes dealing with non-combatants, including prisoners of war, civilians, and refugees, as well as human rights.

Colonies in antiquity were post-Iron Age city-states founded from a mother-city or metropolis rather than from a territory-at-large. Bonds between a colony and its metropolis often remained close, and took specific forms during the period of classical antiquity.Generally, colonies founded by the ancient Phoenicians, Carthage, Rome, Alexander the Great and his successors remained tied to their metropolis, though Greek colonies of the Archaic and Classical eras were sovereign and self-governing from their inception. While earlier Greek colonies were often founded to solve social unrest in the mother-city by expelling a part of the population, Hellenistic, Roman, Carthaginian, and Han Chinese colonies served as centres for trade (entrepôts), expansion and empire-building.

The division of labour is the separation of the tasks in any economic system or organisation so that participants may specialise (specialisation). Individuals, organisations, and nations are endowed with or acquire specialised capabilities, and either form combinations or trade to take advantage of the capabilities of others in addition to their own. Specialised capabilities may include equipment or natural resources as well as skills. Training and combinations of equipment and other assets acting together are often important. For example, an individual may specialise by acquiring tools and the skills to use them effectively just as an organisation may specialise by acquiring specialised equipment and hiring or training skilled operators. The division of labour is the motive for trade and the source of economic interdependence.

An increasing division of labour is associated with the growth of total output and trade, the rise of capitalism, and the increasing complexity of industrialised processes. The concept and implementation of division of labour has been observed in ancient Sumerian (Mesopotamian) culture, where assignment of jobs in some cities coincided with an increase in trade and economic interdependence. Division of labour generally also increases both producer and individual worker productivity.
