Calculations formulas (1 Viewer)

[Haku]

this is a thread to list all the formulas that we need to know for ECONOMICS in the syllabus.

1. Inflation: [CPI(current yr) - CPI(previous yr)] / CPI(previous yr)

please add to the list.

 

[Jago]

BoP = CA + C&FA + omissions and errors

k = 1 / MPS

Economic Growth = (Real GDP - Real GDP previous year) / Real GDP previous year x 100

Real GDP = nomial GDP / CPI x 100

AD = Y = C+I+G+X-M

Participation Rate = Labour Force / Working age population (15+) x 100

unemployment rate = unemployed / labour force x 100

Inflation = (CPI₂ - CPI₁) / CPI₁ x 100

Gini Coefficient = A / (A+B)


those are the ones i can find in my notes

 

[sunjet]

Simple k = Change on Y / Change in S as well which is just 1/MPS

 

[Haku]

or k = 1/(1-MPC). haha

is that it guys? well thats all i can find too when i look into the book.

and by the way the graph of Y = C + I is not needed right? we do not need to know that right?

 

[Jago]

you will need to interpret the graph

 

[Haku]

ok, damn, now i gotta revise over that section.

Current account = Balance on goods and services + net incomes + net transfers

 

[June87]

Terms of trade = prices of exports/prices of imports
Unemployment rate = total unemployed / labour force ( employed + unemployed)

 

[SPYKE_JOE]

1+1 = window (good one to keep in mind for any eco essay)

 

[holla back girl]

^^^as lamn as that was...it was kind of amusing

 

[azza_3761]

MPC = change in consumption/change in income

Y(equilibrium) = (autonomouus comsumption + Investment )/(1-MPC)

 

[jad_9114]

don't forget the NAIRU (non-accelerating inflation rate of unemployment)

[5% + (Unemployment rate - 5%)]/2

 

[Freaky]

^never heard of that... not going to learn it..
