Demand: Quantity demanded is a negative function of the price charged plus a function of other factors. This is written in general form as: Qd = f(P,X) where X is any other non price factors. Examples of mathematical forms for demand functions Qd = ad - bdP + cdX Linear (ie straight line) with X as another factor (eg income) Qd = adP-bdXcd Curved version -also known as multiplicative functional form lnQd = lnad - bdlnP + cdlnX Curved version in log form for easy regression estimation

250-360-1560 Transit Price Elasticities and Cross-Elasticities 25 May 2012 Todd Litman Victoria Transport Policy Institute Abstract This paper summarizes price elasticities and cross elasticities for use in public transit planning. It describes how elasticities are used, and summarizes previous research on transit elasticities. Commonly used transit elasticity values are largely based on studies of short- and medium-run impacts performed decades ago when real incomes where lower and a larger

Price Elasticity Price elasticity is a microeconomics term that indicates ‘how quantity responds to a change in price’ (Colander, 2013, p. 123). There are a few different terms of price elasticity which include Price Elasticity of Demand and Price Elasticity of Supply. According to Colander (2013), Elasticity is a measurement of how one variable can change another (p 123). Elasticity can be either flexible or inflexible or highly elasticity and highly inelasticity. An example of high elasticity
