Document Summary

Condiions: the price level is ixed and real gdp is determined by aggregate demand. Expenditure plans come from households (consumpion), irms (investment), government and people outside of canada (exports) and all domesic may purchase goods produced elsewhere (imports) Sr model assumpions: price level is ixed, aggregate demand (ad) determines real gdp. Y = c + i + g + x m. Consumpion and saving are determined by disposable income (yd) The porion of a change in yd which is spent or saved depends on mpc and mps. Mpc and mps are the slopes of the consumpion funcion and saving funcion, respecively. The porion of a change in real gdp which is spend on imports depends on the marginal propensity to import. Aggregate planned expenditure (ae) = sum of spending plans. Ae is not always the same as actual expenditure and real gdp because spending plans may difer from what is being produced and that afects irms" inventories.

A terrible winter storm causes enormous problems in the

northeastern

part of the United States. This would cause

the short-run aggregate supply curve to shift to the left, but would have no effect on the long-run aggregate supply curve.

Equilibrium real GDP rises after the dollar strengthened. From this we can conclude that

Saving is

the difference between real GDP and disposable income while savings is the difference between disposable income and consumption spending.

the amount one does not consume in a given period of time while savings is the accumulation of past periods of saving.
