In the december, 1969, american economic review (pp. 886-896), nathanial leff reports the following least squares regression results for a cross section study of the effect of age composition on savings in 74 countries in 1964: log s/y = 7.3439 + 0.1596 log y/n + 0.0254 log g - 1.3520 log d1 - 0.3990 log d2 (r2 = 0.57) log s/n = 8.7851 + 1.1486 log y/n + 0.0265 log g - 1.3438 log d1 - 0.3966 log d2 (r2 = 0.96) where s/y = domestic savings ratio, s/n = per capita savings, y/n = per capita income, d1 = percentage of the population under 15, d2 = percentage of the population over 64, and g = growth rate of per capita income. are these results correct? explain

M. cotteleer electronics supplies microcomputer circuitry to a company that incorporates microprocessors into refrigerators and other home appliances. one of the components has an annual demand of 235 units, and this is constant throughout the year. carrying cost is estimated to be $1.25 per unit per year, and the ordering (setup) cost is $21 per order. a) to minimize cost, how many units should be ordered each time an order is placed? b) how many orders per year are needed with the optimal policy? c) what is the average inventory if costs are minimized? d) suppose that the ordering cost is not $21, and cotteleer has been ordering 125 units each time an order is placed. for this order policy (of q = 125) to be optimal, determine what the ordering cost would have to be.
