Suppose that the phillips curve is given by pi subscript t baseline minus pi subscript t superscript e baseline equals 0.08 plus 0.1 mu subscript t minus 2 u subscript tπt−πet=0.08+0.1 μt−2 ut where muμ is the markup of prices over wages. suppose that muμ is initially equal to 20%, but that as a result of a sharp increase in oil prices, muμ increases to 40% in year t and after. why would an increase in oil prices result in an increase in muμ? a. a higher cost of production means changes in technology, which will alter the markup. b. a higher cost of production changes the natural rate of unemployment. c. a higher cost of production changes inflationary expectations and thus the markup. d. a higher cost of production means a higher markup of the price level over wages. what is the effect of the increase in muμ on the natural rate of unemployment? a. the natural rate of unemployment will increase. b. the natural rate of unemployment will decrease. c. the natural rate of unemployment will not change. d. the effect on the natural rate of unemployment cannot be determined without more information

1. alwaysrain irrigation, inc. would like to determine capacity requirements for the next four years. currently, two production lines are in place for making bronze and plastic sprinklers. three types of sprinklers are available in both bronze and plastic: 90-degree nozzle sprinklers, 180-degree nozzle sprinklers, and 360-degree nozzle sprinklers. management has forecast demand for the next four years as follows: both production lines can produce all the different types of nozzles. the bronze machines needed for the bronze sprinklers require two operators and can produce up to 12,000 sprinklers. the plastic injection molding machine needed for the plastic sprinklers requires four operators and can produce up to 200,000 sprinklers. three bronze machines and only one injection molding machine are available. what are the capacity requirements for the next four years? (assume that there is no learning.)
