The connectivity theorems are specific relationships between elasticities and control coefficients. The unscaled elasticities are often depicted in matrix form, called the elasticity matrix. Given the form of the regression equation, we can interpret the coefficients as elasticities. Other recent meta-regression analyses have focused on qualifying elasticities derived from demand functions. Elasticities coefficient can also be computed numerically, something that is often done in simulation software. The growth of market price is determined by the price elasticities of demand and supply. Clarke's kinetic orders are also equivalent to elasticities. Examples include own price elasticities for alcohol, tobacco, water and energy. This is a major advantage of elasticities.
