Gladstone Company tracks the number of units purchased and sold throughout each accounting period but applies its inventory costing method at the time of each sale, as if it uses a perpetual inventory system. Assume its accounting records provided the following information at the end of the annual accounting period, December 31. Transactions Units Unit Cost Beginning inventory, January 1 1,450 $ 50 Transactions during the year: a. Purchase, January 30 2,150 62 b. Sale, March 14 ($100 each) (1,380 ) c. Purchase, May 1 1,130 80 d. Sale, August 31 ($100 each) (1,550 ) Calculate the cost of goods sold and ending inventory for Gladstone Company assuming it applies the LIFO cost method perpetually at the time of each sale.

Suppose that electricity producers create a negative externality equal to $5 per unit. further suppose that the government imposes a $5 per-unit tax on the producers. what is the relationship between the after-tax equilibrium quantity and the socially optimal quantity of electricity to be produced?

Total marketing effort is a term used to describe the critical decision factors that affect demand: price, advertising, distribution, and product quality. define the variable x to represent total marketing effort. a typical model that is used to predict demand as a function of total marketing effort is based on the power function: d = axb suppose that a is a positive number. different model forms result from varying the constant b. sketch the graphs of this model for b = 0, b = 1, 0< b< 1, b< 0, and b> 1. (we encourage you to use excel to do this.) what does each model tell you about the relationship between demand and marketing effort? what assumptions are implied? are they reasonable? how would you go about selecting the appropriate model?
