z-statistic z=Q-μσ=32‚000-25‚00010‚000=0.7 We then look up the standard normal loss function. The expected lost sale is given by. Lz=0.1429 Therefore‚ the expected lost sales = 10‚000 * 0.1429 ≈ 1‚429 Expected sales = 30‚000 – 1‚429 = 30‚571 jerseys 3. First‚ we normalize the order quantity to find its z-statistic z=Q-μσ=28‚000-20‚00010‚000=0.8 In-stock probability = normdist(0.8‚ 0‚ 1‚ 1) = 0.788145 Therefore‚ the probability of filling all demand is 0.788145 4.

Economic problems. The economic problem‚ sometimes called the basic‚ central or fundamental economic problem‚ is one of the fundamental economic theories in the operation of any economy. It asserts that there is scarcity‚ or that the finite resources available are insufficient to satisfy all human wants and needs. The problem then becomes how to determine what is to be produced and how the factors of production (such as capital and labor) are to be allocated. Economics revolves around methods and

Department of Economics University of California‚ Berkeley Fall 2012 Econ 182 Solutions Problem Set 8 Problem 1. Exchange Rates and International Transmission a. Suppose that the US engages in a monetary expansion. Since exchange rate is pegged to the US dollar‚ country X’s monetary authorities are forced to expand their money supply as well (recall that i = i* under FixER). Interest rates fall in country X‚ output expands‚ and of course the exchange rate remains unchanged. On the AA-DD diagram

the supply curve is greater than the shift in the demand curve and the equilibrium price rises. If demand decreases more than the supply‚ the shift in the demand curve is greater than the shift in the supply curve and the equilibrium price falls. 3. What is the effect on the equilibrium in the orange juice market if orange juice becomes more popular and a cheaper robot is used to pick oranges? Because orange juice becomes more popular‚ demand increases and the demand curve for orange juice shifts

Problem Set 2 – Strategy I 1. Why do price misreads (or more generally the inability to observe prices with precision) encourage firms to lower prices? [Note: assume all prices are subject to misreads.] Misreads occur when a firm are competing with no information about competitors and assumes that competitors have taken an uncooperative pricing action when in fact they are cooperative. This assumption makes the firm react in an uncooperative manner‚ lowering the price. This asymmetric information
