Which of the following are equilibrium conditions in the simple Keynesian model?

The chain-weighted output index

A) uses only the current year's prices to calculate growth in real GDP. B) uses prices for the current year and the previous year to calculate growth in real GDP. C) must be calculated only every other year. D) is an inaccurate way to measure growth in real GDP and so has been replaced by the "nominal-to-real" index.

Suppose we are considering the relationship between two variables y and x. y is measured on the y-axis and x is measured on the x-axis, and the relationship between then is a straight line. Suppose that the slope of the line is greater than 1

This slope means that A) a change in x is associated with a bigger change in y. B) a change in x is associated with a smaller change in y. C) a change in x is associated with no change in y. D) a change in x is associated with an equal change in y.
