	Some Estimates of the Contribution of Information Technology to Consumer Welfare
		The appropriate demand curve to use for exact consumer surplus is the compensated demand curve, which is the amount that the consumer would demand if income were adjusted sufficiently to maintain the same utility level.
		Although the demand elasticities were slightly lower, as expected, the results using this approach were not significantly different from the ISUR estimates.
		The Marshallian and Exact estimates of consumer surplus are relatively robust to changes in the estimates for the price elasticity of demand: 50% changes in price elasticity lead to less than 10% changes in the surplus estimates.

		Marshallian surplus: The most common method of estimating consumer surplus is based on the ordinary or the Marshallian demand curve.
		However, the Marshallian surplus is not an exact measure of welfare.
		Imposing such a restriction on the shape of the demand curve may not be appropriate and may lead to misleading estimates.

	SAS/ETS Examples -- Calculating Elasticities in an Almost Ideal Demand System
		Price elasticity is defined as the percentage change in quantity demanded for some good with respect to a one percent change in the price of the good (own price elasticity) or of another good (cross price elasticity).
		The Marshallian demand equation is obtained from maximizing utility subject to the budget constraint, while the Hicksian demand equation is derived from solving the dual problem of expenditure minimization at a certain utility level.
		Elasticities derived from Marshallian demand are called Marshallian or uncompensated elasticities, and elasticities derived from Hicksian demand are called Hicksian or compensated elasticities.

	Marshallian demand function - Wikipedia, the free encyclopedia
		In microeconomics, a consumer's Marshallian demand function specifies what the consumer would buy in each price and wealth situation, assuming it perfectly solves the utility maximization problem.
		Marshallian demand is sometimes called Walrasian demand instead, because the original Marshallian analysis ignored wealth effects.
		Milton Friedman, however, argues that Marshall was misunderstood, that he did account for wealth effects, and that therefore, what is commonly called Marshallian demand is no such thing.

		In mathematics, it is conventional to put the variable from the left-hand side of an equation on the vertical axis of a graph.
		Since you are accustomed to the latter convention, it will be easier for you to draw graphs of supply and demand curves if you first invert them; that is, solve for p as a function of q.
		For the demand curve above, subtract 300 from both sides then divide both sides by —20 to get: pd = 15 — q/20 Note that the subscript d is now attached to p, rather than q.

		Observed demand functions are assumed to be the outcome of a maximisation exercise.
		The point of all this is that the solutions for the x’s are implicit functions of M and p and are known as the Marshallian demand functions.
		This is obtained by substituting the Marshallian demands into the direct utility function.

	MPSGE: Imperfect Competition
		(Demand functions are undefined for negative income.) In order to deal with this situation, we introduce a transfer variable, BAILOUT, which transfers labor income from consumers to the monopolist if markups revenues do not cover fixed costs.
		The Marshallian approximation to the elasticity of demand in these models is given by: e = sigma - (sigma -1) sharex where sigma is the elasticity of substitution in demand and sharex is the value share of good x in final demand.
		Markup revenues are converted to demand for fixed costs using an "entrepreneur", as in M3-2.

	Income elasticity of demand - Wikipedia, the free encyclopedia
		A negative income elasticity of demand is associated with inferior goods; an increase in income will lead to a fall in the quantity demanded and may lead to changes to more luxurious substitutes.
		A zero income elasticity of demand is an increase in income without leading to a change in the quantity demanded of a good.
		Many necessities have an income elasticity of demand between zero and one: expenditure on these goods may increase with income, but not as fast as income does, so the proportion of expenditure on these goods falls as income rises.

	PKT message, Marshallian varient of classical economics
		As I said Sidney Weintraub was able to take these Marshallian Microfounda tions of Keynes's GT and develop Marshallia demand and supply curves for the labor market.
		In it Keynes notes (p.186n.1) that the "equality between the stock of capital-goods offered and the stock demanded will be brought about by the PRICES of capital goods, not the rate of interest".
		How this is developed into Marshallian demand and supply curves I first developed in ECONOMETRICA in 1967, then in MONEY AND THE REAL WORLD in 1972 (ch.4) and finally in Chapter 4 of PKMT.

	EconPapers: Asymptotically Well-behaved Demand Functions for Normal Goods (Site not responding. Last check: 2007-10-17)
		It is well-known that Marshallian demand functions are well-behaved only if they are defined for neutral goods, i.e., the case of quasi-linear preferences.
		This paper considers a possibility that Marshallian demand functions for normal goods become well behaved when the initial incomes are sufficiently large.
		As a main result, this paper provides necessary and sufficient conditions for a standard preference ordering under which the derived Marshallian demand function becomes well-behaved when the initial income is sufficiently large.

		Marshallian demand curve is not always negatively sloped.
		In the case of a normal good, Marshallian demand curve is always flatter than the compensated demand curve.
		For this reasons, we can compare the elasticities of demand for automobiles in Germany and in Japan, although their demand curves are expressed in terms of mark and yen prices.

		In our classrooms we draw the Marshallian cross to depict competitive supply and demand, and then go on to explain how the market is cleared only at the price corresponding to the intersection of the curves.
		Instead of drawing horizontal price lines on the demand-supply diagram to show excess supply or unmet demand, the Marshallian procedure uses vertical lines to mark off the demand prices and the supply prices for given quantities.
		With this procedure the ordinate of a point on the demand curve indicates the maximum price at which a quantity (represented by the abscissa of the point) will be sold.

	Wine Demand and Pricing Strategy
		They are based on the use of the Marshallian demand curve, which is the most widely used demand curve in which the responsiveness of quantity demanded to price incorporates both the income effe ct (see below) and the substitution effect (see below).
		This is in contrast to the compensated or Hicksian demand curve, where income effects are netted out.
		A firm may try to move the demand for their product towards a more inelastic demand by differentiating it.

		Thus, D (a) the Hicksian demand curve for X is steeper than the Marshallian demand curve.
		Along a Marshallian demand curve for a given good, A (a) the consumer’s utility is increasing as quantity of the good increases.
		Thus, (own-price) elasticity of demand for Cobb-Douglas utility is constant and unit-elastic.

		The Marshallian demand functions characterize consumption behavior for a rational household.
		The first term on the right-hand side of (3) is the Marshallian price effects, while the second term reflects income effects.
		As in the traditional model of consumer demand, the matrix of Hicksian price effects can be shown to be symmetric, negative semi-definite.

	Further evidence of positively sloping marginal revenue. \| Business solutions from AllBusiness.com
		These results are obtained in the two good case, for which the authors derive the marginal revenue function from the consumer's inverse demand function for good 1.
		The Marshallian demand function for good 1 has the general form [x.sub.1] = f([p.sub.1], [p.sub.2], y).
		In this paper we examine the behavior of the marginal revenue function derived from the Marshallian demand function which corresponds to a CES utility function with minimum subsistence requirements.

		The substitution effect is also isolated on the Hicksian demand curve.
		The easiest way to think about the intuition behind this is to realize that as your real income rises (which could occur because a price drops) you may decide to actually buy less of some goods because you prefer other goods instead now that you have more money.
		The combination of the two effects can be shown in the budget constraint/utility curve graph where both the income and substitution effects are summed together (this is known as the PCC curve) and with the Marshallian or ordinary demand curve.

		An ordinary (Marshallian) demand curve is constructed by holding constant the consumers’ money income and allowing his level of welfare to change as the price changes.
		A compensated (Hicksian) demand curve is constructed by varying the consumers’ money income in such a way as to hold his level of welfare constant at all points on the curve.

	SSRN-Simple Utility Functions with Giffen Demand by Peter Sorensen (Site not responding. Last check: 2007-10-17)
		We present some simple utility functions whose Marshallian demand functions possess the Giffen property: at some price-wealth pairs, the demand for a good marginally increases in response to an increase in its own price.
		The utility functions satisfy standard preference properties throughout the usual consumption set of non-negative bundles: continuity, monotonicity, and convexity.

	Formal derivation of demand systems
		If U(q) is twice continuously differentiable (then the Hessian of U(q) is symmetric and) then it is possible to obtain a Marshallian demand function
		Therefore if U(q) has a diminishing MRS, the demand equations are continuously differentiable.
		In micro economics the Hicksian demand function is equal to the Marshallian function which is "compensated" for the change in real income (such that the original utility level is attained).
