Cross subsidization is the practice of charging higher prices to one type of consumers to artificially lower prices for another group.State trading enterprises with monopoly control over marketing agricultural exports are sometimes alleged to cross subsidize, but lack of transparency in their operations makes it difficult, if not impossible, to determine if that is the case.
An example would be an increase in disposable income arising from a decrease in price of an essential good or service that the government has enforced in a form of monetary support. In contrast, a decrease in the price of a good or service may lead to an increase in revenue for producers earned from the heightened demand by consumers.
In mathematics, the Kronecker product, sometimes denoted by ⊗, is an operation on two matrices of arbitrary size resulting in a block matrix.It is a specialization of the tensor product (which is denoted by the same symbol) from vectors to matrices and gives the matrix of the tensor product linear map with respect to a standard choice of basis.
The concept of cross-boundary subsidies developed out of a merging of ideas from the studies of landscape ecology and food web ecology. The ideas from landscape ecology allow the study of population, community, and food web dynamics to incorporate spatial relationships between landscape elements into an understanding of such dynamics (Polis et al. 1997).
Mathematical statistics is the application of probability theory and other mathematical concepts to statistics, as opposed to techniques for collecting statistical data. [1] Specific mathematical techniques that are commonly used in statistics include mathematical analysis , linear algebra , stochastic analysis , differential equations , and ...
Differential equations are an important area of mathematical analysis with many applications in science and engineering. Analysis is the branch of mathematics dealing with continuous functions , limits , and related theories, such as differentiation , integration , measure , infinite sequences , series , and analytic functions .
Mathematical economics is the application of mathematical methods to represent theories and analyze problems in economics.Often, these applied methods are beyond simple geometry, and may include differential and integral calculus, difference and differential equations, matrix algebra, mathematical programming, or other computational methods.
[12] [13] [clarification needed] After calculating the cross-correlation between the two signals, the maximum (or minimum if the signals are negatively correlated) of the cross-correlation function indicates the point in time where the signals are best aligned; i.e., the time delay between the two signals is determined by the argument of the ...
