2. Productivity:
relationship between output & labor
x jt For the entire economy
π jt = as well as for each sector
Ljt at any given point in time

6. Relations
Output (x) is produced because:
([ ])
x = [I − A ]
~
−1
y = h I−A
T T
~
• There is final demand y & industrial demand A
T
• Payments & purchases A are made
h

7. Important issues
Output production & allocation
Employment generation
Productivity (produce more with less)
Payments to factors of production
Wages & Salaries
Profits
Rent & other

8. Underlined principles
Whenever there is a market to sell
PRODUCTION increases
Whenever productivity increases
there is not necessarily
increase in employment

9. Net result
Is there any growth?
Do people have work?
Do they get ‘sufficient’ income

10. General Sectoral Outlook
of the Turkish Economy
Output & Employment relations
Sales
of final products & industrial sales
Payments
for value added & industrial purchases
