Each firm knows the quantity supplied by the other firm in the previous period and assumes that this is what it will supply in the next period. Subtract Q from linear market demand curve to construct own demand and MR curve to determine profit maximizing Q. Quantities will change each period until they are equal

Q

Shifts in Short Run Agg Supply Curve

A

  • Input Prices: decrease in wages or prices of other inputs increases production
  • Expectations of future output prices
  • Taxes and govt. subsidies: decrease in taxes, increase subsidies decrease cost of production and increase output

Keynesian School

A

Shifts in aggregate demand due to changes in expectations primary cause of business cycles. Fluctuations due to swings in the level of optimism of those who run businesses (overinvest and overproduce when too optimistic). Wages are downward sticky (decrease in wages unable to increase short-run aggregate supply and move from recession back to full employment). Increase aggregate demand through monetary policy or fiscal policy

Q

Monetarist School

A

Variations in aggregate demand that cause business cycles are due to variations in the rate of growth of the money supply, likely from inappropriate decisions by monetary authorities.

Austrian School

A

Business cycles caused by government intervention in the economy. Policymakers forcing interest rates down to artificially low levels, firms invest too much capital in the long term compared to actual consumer demand

125
Q

New Classical School

A

Real Business Cycle theory. Emphasizes effect of real economic variables such as changes in technology and external shocks, as opposed to monetary variables, as the cause of business cycles.
