Reversal theory is a structural, phenomenological theory of personality, motivation, and emotion in the field of psychology. [1] It focuses on the dynamic qualities of normal human experience to describe how a person regularly reverses between psychological states, reflecting their motivational style, the meaning they attach to a situation at a given time, and the emotions they experience.
The backwardness model is often contrasted with the Rostovian take-off model developed by W.W. Rostow, which presents a more linear and structuralist model of economic growth, planning it out in defined stages. The two models are not mutually exclusive, however, and many countries appear to follow both models rather adequately.
Psychophysiological economics differs from behavioral economics by focusing on direct measures of physiological change and observational data, in addition to attitudinal measurement. Psychophysiological economics also differs from functional magnetic resonance imaging , which is typically applied exclusively to the study of brain activity.
In economics a trade-off is expressed in terms of the opportunity cost of a particular choice, which is the loss of the most preferred alternative given up. [2] A tradeoff, then, involves a sacrifice that must be made to obtain a certain product, service, or experience, rather than others that could be made or obtained using the same required resources.
If output increases by the same proportional change as all inputs change then there are constant returns to scale (CRS). For example, when inputs (labor and capital) increase by 100%, output increases by 100%. If output increases by less than the proportional change in all inputs, there are decreasing returns to scale (DRS). For example, when ...
