Rapidly metabolizing tissues generate large amounts of protons and carbon dioxide. The result of this increase in protons and carbon dioxide is the oxygen-binding curve of hemoglobin O changes shape from sigmoidal to hyperbolic. O shifts to the left, meaning more binding of O2 at lower O2 levels. O remains the same. O shifts to the right, meaning lower saturation at higher O2 levels.

9. What are the two parts of the Fed's dual mandate? Answer the following with the dual mandate and bullseye chart in terms of signals to the Fed about the status of the economy. The Fed's dual mandate, given to it by Congress, states that the Fed's two highest objectives are to promote maximum employment and stable prices. The bullseye chart was developed by the Federal Reserve Bank of Chicago. It is a visual comparison of the current state of the economy with the Fed's dual mandate. The chart shows the inflation rate on the horizontal axis and the unemployment rate on the vertical axis and has crosshairs where the two targets meet. The southwest (lower left) and northeast (upper right) quadrants send conflicting messages about which monetary policy is appropriate. If the point showing the actual rates of unemployment and inflation lies in the southwest quadrant, it suggests that the Fed should be inclined toward an expansionary monetary policy. But the fact that the inflation rate is below 2 percent suggests that a contractionary policy is in order. If the point showing the actual rates of unemployment and inflation lies in the northeast quadrant of the center of the bullseye, the opposite problem exists. There, the unemployment rate will be suggesting an expansionary monetary policy (to reduce the unemployment rate down to the 4.3 percent target) while the inflation rate will be suggesting a contractionary monetary policy (to reduce the inflation rate down to 2 percent). 10. Define the Taylor rule. The Taylor rule is a monetary rule proposed by economist John Taylor that would stipulate exactly how much the Federal Reserve System should change interest rates in response to divergences of real GDP from potential GDP and divergences of actual rates of inflation from the target rate of inflation. The Fed target interest rate = real risk-free interest rate + current actual inflation rate + 0.5 x inflation gap - 1.0 x unemployment gap. The Taylor Rule is based on economists' widely held belief that central bankers are willing to tolerate modest positive rates of inflation if doing so will help to generate low inflation and full employment. To capture that preference, in the Taylor rule equation, the coefficient on the inflation gap is positive while the coefficient on the unemployment gap is negative.
