In economics, economic equilibrium is a situation in which the economic forces of supply and demand are balanced, meaning that economic variables will no longer change. [ 1 ] Market equilibrium in this case is a condition where a market price is established through competition such that the amount of goods or services sought by buyers is equal ...
A measure of total gains from trade is the sum of consumer surplus and producer profits or, more roughly, the increased output from specialization in production with resulting trade. [8] Gains from trade may also refer to net benefits to a country from lowering barriers to trade such as tariffs on imports .
Joseph Stiglitz applied factor price equalization to a dynamic economy to study the long term supply responses of capital from the classical perspective. He showed that the high interest economy is eager to trade with the low interest rate economy, and consequently it has a lower long term consumption in free trade than pre-trade.
Calculating the equilibrium price of just one good, in theory, requires an analysis that accounts for all of the millions of different goods that are available. It is often assumed that agents are price takers , and under that assumption two common notions of equilibrium exist: Walrasian, or competitive equilibrium , and its generalization: a ...
New Trade Theory analyses individual enterprises and plants in an international competitive situation. The classical trade theory—i.e., the Heckscher–Ohlin model—has no enterprises in mind. The new trade theory treats enterprises in an industry as identical entities. "New" New Trade Theory (NNTT) gives focus on the diversity of enterprises.
In mathematical economics, the Arrow–Debreu model is a theoretical general equilibrium model. It posits that under certain economic assumptions (convex preferences, perfect competition, and demand independence), there must be a set of prices such that aggregate supplies will equal aggregate demands for every commodity in the economy.
In economics, a price mechanism refers to the way in which price determines the allocation of resources and influences the quantity supplied and the quantity demanded of goods and services. The price mechanism, part of a market system , functions in various ways to match up buyers and sellers: as an incentive, a signal, and a rationing system ...
In contrast, in an exchange economy with production, some or all agents are firms that may also produce new goods. [2]: 313 A major interesting question regarding an exchange economy is if and when the economy attains a competitive equilibrium. Exchange and distribution efficiency are concerned.
