Since quantum characteristics in physics like superposition and entanglement are a result of the imaginary numbers, Baaquie's numerical success must result from effects other than quantum ones. [ 18 ] : 668 Rickles critiques Baaquies's work on economics grounds: empirical economic data are not random so they don't need a quantum randomness ...
The editorial in the inaugural issue of the journal Quantum Economics and Finance says: "Quantum economics and finance is the application of probability based on projective geometry—also known as quantum probability—to modelling in economics and finance. It draws on related areas such as quantum cognition, quantum game theory, quantum ...
Wiesner's quantum money scheme was first published in 1983. [1] A formal proof of security, using techniques from semidefinite programming, was given in 2013. [2]In addition to a unique serial number on each bank note (these notes are actually more like cheques, since a verification step with the bank is required for each transaction), there is a series of isolated two-state quantum systems.

Quantum finance involves applying quantum mechanical approaches to financial theory, providing novel methods and perspectives in the field. [40] Quantum finance is an interdisciplinary field, in which theories and methods developed by quantum physicists and economists are applied to solve financial problems. It represents a branch known as ...
Annual median equivalised disposable income per person, by OECD country. [2]The median equivalised disposable income is the median of the disposable income which is equivalised by dividing income by the square root of household size; the square root is used to acknowledge that people sharing accommodation benefit from pooling at least some of their living costs.
In contrast, by definition, the real value of the commodity bundle in aggregate remains the same over time. The real values of individual goods or commodities may rise or fall against each other, in relative terms, but a representative commodity bundle as a whole retains its real value as a constant from one period to the next.
Economic historian Mark Blaug has called the quantity theory of money "the oldest surviving theory in economics", its origins originating in the 16th century. [1] Nicolaus Copernicus noted in 1517 that money usually depreciates in value when it is too abundant, [2] which is by some historians taken as the first mention of the theory.
For the 80th acre, her marginal willingness to pay has decreased down to zero. Figure 2: Tom's marginal willingness to pay. Figure 2 shows Tom's marginal willingness to pay for a public park. Unlike Sarah, for the first acre of park he is willing to pay $40, and for the 40th acre of park he has a marginal willingness to pay of $20.
