Before taking
any strategic decision managers have to indentify
the pertinent macroeconomic aggregates, the
relations between them and their TRENDS.
| Aggregates |
GDP
= C + I + G + X - M |
| GDP |
total value of final goods
and services produced within a nation
during a given year |
| C |
Household consumption of goods and services |
| I |
physical investment (gross private capital
formation) + additions to inventory |
| G |
Government expenditures |
| X |
Exports |
| M |
Imports |
Three
approaches to calculate GDP
| Approaches |
GDP (Gross Domestic Product) |
| Flow-of-product
approach |
C + I + G + (X
- M) (open
economy) (assumptions
: depreciation = 0, indirect taxes=0) |
| Earnings approach |
Sum of earnings received by household
from firms (wages, rents, interests,
profits) |
| Value-added approach |
GDP = total value added produced by
firms |
Relation
between International Trade & Internal
Macroeconomics
GDP =
C + I + G +( X - M)
GDP -
C - G = S = I + (X - M)
(S - I)
= (X - M)
If X is not equal to M,
that is because S (savings) is not equal
to I. If we want to restore the equilibrium
between X and M, we have to restore
the equilibrium between S and I by using
the three macroeconomic policies :
