Search theory is a branch of microeconomics that studies decisions of this type. The costs of searching are divided into external and internal costs. External costs include the monetary costs of acquiring the information, and the opportunity cost of the time taken up in searching. External costs are not under the consumer's control, and all he ...
Time value of money. The present value of $1,000, 100 years into the future. Curves represent constant discount rates of 2%, 3%, 5%, and 7%. The time value of money is the widely accepted conjecture that there is greater benefit to receiving a sum of money now rather than an identical sum later.
The slope of the production–possibility frontier (PPF) at any given point is called the marginal rate of transformation ( MRT ). The slope defines the rate at which production of one good can be redirected (by reallocation of productive resources) into production of the other. It is also called the (marginal) "opportunity cost" of a commodity ...
Opportunity costs are unavoidable constraints on behaviour because one has to decide what's best and give up the next-best alternative. Price theory [ edit ] Microeconomics is also known as price theory to highlight the significance of prices in relation to buyer and sellers as these agents determine prices due to their individual actions.

t. e. The subjective theory of value (STV) is an economic theory for explaining how the value of goods and services are not only set but also how they can fluctuate over time. The contrasting system is typically known as labor theory of value . STV's development helped to better understand human action and decision making in economics.
New trade theory (NTT) is a collection of economic models in international trade theory which focuses on the role of increasing returns to scale and network effects, which were originally developed in the late 1970s and early 1980s. The main motivation for the development of NTT was that, contrary to what traditional trade models (or "old trade ...
In economics, the marginal cost is the change in the total cost that arises when the quantity produced is increased, i.e. the cost of producing additional quantity. [1] In some contexts, it refers to an increment of one unit of output, and in others it refers to the rate of change of total cost as output is increased by an infinitesimal amount.
Rational choice theory (criminology) In criminology, rational choice theory adopts a utilitarian belief that humans are reasoning actors who weigh means and ends, costs and benefits, in order to make a rational choice. This method was designed by Cornish and Clarke to assist in thinking about situational crime prevention. [1]
