In thermodynamics, the Joule–Thomson effect (also known as the Joule–Kelvin effect or Kelvin–Joule effect) describes the temperature change of a real gas or liquid (as differentiated from an ideal gas) when it is expanding; typically caused by the pressure loss from flow through a valve or porous plug while keeping it insulated so that no heat is exchanged with the environment.
The state-power theory as put into perspective by Stephen Krasner (1976), explains that the structure of international trade is determined by the interests and power of states acting to maximize their aggregate national income, social stability, political power and economic growth. Such state interests can be achieved under free trade.
International trade theory is a sub-field of economics which analyzes the patterns of international trade, its origins, and its welfare implications.

New trade theory and "new" new trade theory (NNTT) need their own trade theory. New trade theories are often based on assumptions such as monopolistic competition and increasing returns to scale. One of the typical explanations, given by Paul Krugman, depends on the assumption that all firms are symmetrical, meaning that they all have the same ...
The Rybczynski theorem was developed in 1955 by the Polish-born English economist Tadeusz Rybczynski (1923–1998). It states that at constant relative goods prices, a rise in the endowment of one factor will lead to a more than proportional expansion of the output in the sector which uses that factor intensively, and an absolute decline of the output of the other good.
Trump also ordered 25% tariffs on Mexican and Canadian goods, but he delayed them just hours before the sweeping actions were set to go into effect until March 1.
Empirical investigations of the J curve have sometimes focused on the effect of exchange rate changes on the trade ratio, i.e. exports divided by imports, rather than the trade balance, exports minus imports. Unlike the trade balance, the trade ratio can be logarithmically transformed regardless of whether a trade deficit or trade surplus ...
