Refer to the Article Summary. The convertible peso (CUC) is worth 25 times the peso (CUP), yet Cuban officials have for years treated the two currencies as being of equal value. This indicates that the peso (CUP) is ________ compared to the convertible peso (CUC), and would need to be ________ for the two currencies to reach the market equilibrium exchange rate.

Sensitivity analysis of the results may include the following with the exception of

A) stability over time analysis of the estimated multipliers. B) using homoskedasticity only rather than HAC standard errors. C) investigation of omitted variable bias. D) looking at different computations of the HAC standard errors.

Using Figure 1 above, if the aggregate demand curve shifts from AD2 to AD1 the result in the long run would be:

A. P4 and Y1. B. P4 and Y2. C. P5 and Y1. D. P5 and Y2.
