Excerpt: ... lesson06 Page 1 of 2 Unit 2 > Lesson 6 Consumer Behavior and Utility Maximization Introduction Consumer behavior is an essential component of microeconomics. Remember in Chapter 1, we said microeconomics was concerned with the trees in the forest and not the overall forest. How consumers react to price changes, with limited income helps explain the law of demand. Chapter 8 discusses consumer utility (satisfaction), marginal utility, the law of diminishing marginal utility, and the maximizing utility rule. All of these are important in determining the behavior of consumers. Objectives At the end of this lesson you should be able to: define and distinguish between the income and substitution effects of a price change. explain why a consumer will buy more of a commodity when its price falls by using the income and substitution effects. explain why a consumer will buy less of a commodity when its price rises by using the income and substitution effects. define marginal utility and state the law of diminishing ...

Economics 103 Lecture # 4 Diminishing Marginal Value The Third Principle in Economics is Diminishing Marginal Value It doesnt matter what the good, the more you have the less youre willing to pay for more. -your boyfriend/girlfriend? - child? -water? - married couples in restaurants Why is variety the spice of life? Why do you consume everyday but get paid every fourteen? Why do you save over the life-cycle? Some things to note: - maximum willingness to pay = MV. - Principle number 3 refers to a rate of consumption. - everything else is held constant. income, prices, laws, etc. What are the three principles that describe preferences? 1) Maximization 2) Substitution 3) DMV Even though everyone is assumed to behave according to these principles, there is lots of room for differences. What Prevents us from consuming whatever we want? The Budget Constraint.

It takes Lynn an entire hour (the third hour) to produce her eighth mitten. Thus, her marginal cost is $15 per mitten to produce the eighth mitten. Q8.

ECO365 Week 2 Prof Comments
University of Phoenix, BUS ECO 365
Excerpt: ... ECO365 Week 2 Professor Comments This additional lecture will cover the most important concepts to take away from week 2. These concepts are: diminishing marginal productivity, technical and economic efficiency, economies and diseconomies of scale, demand and supply of labor, and income redistribution. First the law of diminishing marginal productivity. Diminishing marginal productivity occurs when adding more production inputs (ie labor) to a fixed input (ie capital) results in slower output growth. Initially, as inputs are added to the production process, output increases and exhibits increasing marginal productivity. However, at some point the increase in output will slow and eventually decline (ie negative marginal productivity). For example, as more labor is added to a fixed amount of capital output will increase. But at some point adding more labor will not achieve constant output growth because too much labor (with a fixed amount of capital) becomes unproductive. This concept can be seen by looking at ...

Note that points will be awarded based only on your reasoning, not on the answer itself, even if correct. (1) (T,F,U) A wise entrepreneur will minimize costs for a given output rather than maximizing output for a given cost (2) (T,F,U) You should quit studying once you reach the point of diminishing marginal returns. (3) (T,F,U) Diminishing marginal returns to labor need not imply decreasing returns to scale. However, increasing marginal returns to labor would imply increasing returns to scale. (4) Show that production function f (k, l) = k 2 + l, k 0, l 0 does not represent a decreasing, increasing, or constant returns to scale technology.

Econ 1 section 7 Corey Garriott (cgarriott@ucla.edu) Feb. 25, 2008 There are no section 6 notes posted because I just went over the midterm that day (to the, oh, six students who showed up for it). As for the session we missed during President's Day, let's talk about how to handle that today. I am going to cover lectures 11 and 12 today. Lecture 11 appears to restate much of lecture 10, so I will skip it so we can get caught up after President's Day. 1 Definitions Utility: Any measure that is interpreted as a ranking. Marginal utility: The change in utility caused by eating/using/having one additional unit. Diminishing marginal utility: A downward sloping marginal utility schedule (i.e. on a graph). Rational: This is a big one in economics. An agent is "rational" if its goal in life is to maximize a quantity (utility) acting strategically using all the information available to it exhaustively and without making mistakes. Maybe that doesn't sound like what you mean by rationality, but economis ...

Excerpt: ... Chapter 3 Homework Key 1. Consider the utility function U ( x , y ) Due: February 20, 2007 y x with MU x y / 2 x and MU y x. a. Does the consumer believe more is better for each good? Explain. Since U increases whenever x or y increases, more of each good is better. This is also confirmed by noting that MUx and MUy are both positive for any positive values of x and y . b. Do the consumer's preferences exhibit a diminishing marginal utility of x? Explain. Is the marginal utility of y diminishing? Explain. Since MU x y 2 x , as x increases (holding y constant), MU x falls. Therefore the marginal utility of x is diminishing. However, MU y x . As y increases, MUy does not change. Therefore the preferences exhibit a constant, not diminishing, marginal utility of y. 2. The utility that Julie receives by consuming food F and clothing C is given by U ( F ,C ) For this utility function, the marginal utilities are MU F FC . C and MU C F. a.
