8. Effects of Elasticity on the Responsiveness of Revenue to Price Changes Along Linear Demand Functions

The student is expected to understand the following aspects of the relationship between elasticity and revenue, given price changes on a linear demand schedule: revenue changes in response to price changes depend upon elasticity; elasticity changes along a linear demand function ; when elasticity is greater than one (elastic), price changes and revenue changes are inverse; when elasticity is less than one (inelastic), price changes and revenue changes are direct; the slope and intercept on a linear demand function affect elasticity at a given level of quantity demanded [Details...]

9. Model of Consumer Behavior: Constrained Optimization

The purpose of this Module on Consumer Behavior is to explain income constrained utility maximization. A graphical solution to the optimization process is offered to illustrate the consumers selection of consumption quantities of two available goods given a budget constraint during a fixed time period. The income constrained utility maximizing quantities of the goods are gotten assuming prices and income are predetermined and consumption is subject to satiation. Students are expected to understand graphical depictions of pivotal aspects of the optimization process: indifference curves; the income constraint and; the optimization condition using the slopes of the curve and constraint. [Details...]

10. Model of Consumer Behavior: Law of Demand

Consumer behavior using Income constrained utility maximization provides a specification for the consumers objective function. The resulting quantities of two available goods that are selected using this algorithm maximize satisfaction given income. Using this model of consumer behavior shows that the resulting maximizing quantities of a good that correspond to different prices are those that demonstrate the inverse relationship between price and quantity demanded. Studens are expected to understand the following aspects of the graphical depiction of the law of demand using income constrained utility maximization: the effect of changing a product price on the income restraint; the consequences of changes in the product prices on the utility maximizing quantity of the product; how to derive the Law of Demand using a set of product prices and the model of consumer behavior (income constrained utility maximization). [Details...]

11. Elasticity

Elasticity is a measure of responsiveness. It tells how much one thing changes when you change something else that affects it. For example, the elasticity of demand tells us how much the quantity demanded changes when the price changes. The elasticity of demand measures the responsiveness of quantity demanded to changes in the price charged. The following discussion mostly uses the elasticity of demand for its examples. The elasticity concept can be used for other things, too, like supply or income. [Details...]

12. Elasticity -- A Quantitative Approach

The first elasticity tutorial took a qualitative approach to elasticity. The idea conveyed was Elasticity = Responsiveness The elasticity of Q with respect to P is the responsiveness of Q to changes in P. Elasticity has a quantitative meaning, a specific way of measuring responsiveness. Suppose P changes, and Q changes as a result. The elasticity of Q with respect to P is the relative change in Q divided by the corresponding relative change in P. [Details...]

General Equilibrium - Interactive Tutorial

32. Completing Markets: Options and Long-Lived Securities

Options are one of the more interesting securities to which arbitrage reasoning can be applied. (European) options, recall, are assets who derive their value from an underlying security, thus they have a return structure ro = [max(0, r1 - c), max(0, r2 - c), .., max(0, rS-c)] where r1, r2, .., rS are the returns on the underlying security and c is the "strike" price. The strike price is the asset price at which the owner of the option is entitled to buy (if a call option) or sell (if a put option) a unit of an underlying security if he decides to "exercise" it. One of the more interesting results, as stressed by Stephen Ross (1976), is that we can use options to "complete" incomplete markets: specifically, we can construct options to span a space when there are an insufficient number of fundamental assets.
