The duality theorems have two interpretations: one Duality the producer context and the other in the consumer context. The chapter discusses a variety of other duality theorems—that is, other methods for equivalently describing tastes or technology.

Consumer theory studies how rational consumer chooses what bundle of goods to consume. Special case of general theory of choice. Key new assumption: choice sets defined by prices of each of n goods, and income (or wealth). No quantity discounts or supply constraints.

Consumer Theory Jonathan Levin and Paul Milgrom October 1 The Consumer Problem Consumer theory is concerned with how a rational consumer would make consump-tion decisions. What makes this problem worthy of separate study, apart from the general problem of choice theory, is its particular structure that allows us to de.

-Duality: Alternative way of looking at the consumer's utility maximization decision. Rather than choosing the highest indifference curve, given a budget constraint, the consumer chooses the lowest budget line that touches a given indifference curve. -希克斯替代效应(Hicksian substitution effect)与斯勒茨基替代效应.

At point e 1 the consumer buys quantity x 1 at price y 1. At point e 2 the price, y 2, is lower than y 1, and the quantity demanded has increased to x 2, and so on. We may plot the price- quantity pairs defined by the points of equilibrium (on the price-consumption line) to. Indifference curves are lines in a coordinate system for which each of its points express a particular combination of a number of goods or bundles of goods that the consumer is indifferent to consume.

This is, the consumer will have no preference between two bundles located in the same indifference curve, since they all provide the same degree of utility. Consumer behavior 1. The Theory of Consumer Behavior 2.

Consumers play an important role in determining the demand for a firm‟s products. They are quality conscious and price sensitive. The success of a product is dependent on the consumers‟ acceptance of the product.

Weak and strong duality weak duality: d⋆ ≤ p⋆ • always holds (for convex and nonconvex problems) • can be used to find nontrivial lower bounds for difficult problems for example, solving the SDP maximize −1Tν subject to W +diag(ν) 0 gives a lower bound for the two-way partitioning problem on page 5–7 strong duality: d⋆ =p⋆.

A Preview of Duality Recall that the shadow prices were interpreted as breakeven rents for capacity at the margin. Imagine for the moment that the firm does not own its productive capacity but has to rent it.

Now consider any values for the shadow prices, or rental rates, that satisfy the above constraints, say y1 =4 and y2 =4.

The two theoretical tools of consumer theory are utility functions and budget constraints. Out. Using a strong duality theorem, one can prove optimality of a primal solution by constructing a dual solution with the same objective function value.

• Sensitivity analysis of the primal problem. The dual variable on a constraint represents the incremental change in the optimal solution value per unit increase in the RHS of the constraint.

The emphasis is not on providing mathematically general proofs; instead, a geometric approach is used to provide, in an informal way, an intuitive understanding of duality theory. This book introduces the most common alternative ways of representing preferences and technologies, such as indirect utility and distance functions, expenditure and.

Producers, Consumers, and Partial Equilibrium provides a systematic and accessible presentation of the full formal details in the core theories of producer and consumer choice under conditions of price taking; and covers the standard theories of competitive, monopoly, and oligopoly partial equilibrium among these economic actors.

The book pulls together foundational content from Reviews: 1. Duality in Consumer Theory. Vijay Krishna and Hugo Sonnenschein.

Introduction The dual approach to demand theory is based on the fact that preferences can be represented in two forms other than the utility function; these are the expenditure function and the indirect utility function. Let U: R~. The idea of duality has proved to be a powerful device in modern work on the economics of consumer behaviour.

The authors have used duality to provide an integrated and accessible treatment of this subject. The book focuses on applications of the theory to welfare economics and econometric analysis. The book begins with four chapters that Reviews: 9.Microeconomics deals with the ‘individual’ part of this duality – the rationality behind the decisions of an individual given the constraints of limited resources.

By definition, microeconomics is concerned with the interaction of an economic agent (buyer/seller) with the market, push/pull of supply and demand and the resultant swings in.The theory of consumer behaviour in fast food marketing: strategies for quantity of food items the consumer can buy given his or her level of income.
