An open economy is an economy in which there are economic activities between the domestic country with the other countries.

AD = C + I + G + (X-M)
Marginal Propensity to consume refers to the percentage change in consumption for every one rupee of change in the income. It is the ratio between the change in income and corresponding change in consumption.
Mathematically,
Consumption function (C) = c+ bY where c=autonomous consumption, b= marginal propensity to consume, and Y= income.
Therefore, marginal propensity to consume is expressed as a product with the income earned by the economy.
The estimated values of GDP are called ex ante which refers to the planned aggregates of all economic variables. For example, ex ante savings and ex ante investment which refers to the planned savings and planned investment of an economy in a specified period of time.
