All the formulas and explanations of macro and micro economics

β=1-（αi）/y*。

The formula y*=(i) (1-) shows that the national income of this clearly two-sector economy is premised on the assumption that there is only ** sector and the private sector (residents). In a two-sector economy, the equilibrium national income is the national income when investment and savings are equal, y=c+i.

When it is assumed that the consumption function c= +y (Keynesian consumption function, Western economics.

Macroeconomics is introduced by any author in the textbook.

will be this function), then the equilibrium income formula is y=(i) (1- ) and the investment is a function of the interest rate, i.e., i=e-dr, and the equilibrium income formula becomes y=(e-dr) (1-).

Note. Pay attention to the primary allocation.

The relationship between efficiency and fairness should be properly handled in both redistribution, and redistribution should pay more attention to fairness. The primary distribution should be made in relation to the individual's income in relation to economic activity.

In the redistribution with the participation of the state, it is necessary to strengthen the regulation of income distribution, raise the income level of low-income people, regulate excessively high income, and ban illegal income. By improving the tax and social security systems.

It is necessary to control the income gap within a certain range, prevent serious polarization, and ensure the basic livelihood of low-income people.

Help, I'm studying macroeconomics right now, it's simply not human, it's too difficult, and a bunch of formulas are dazzling.

1. The expenditure expression of the GDP of the general four-sector economy: GDP = C + i + G + (x-m), X - M = nx is called net exports;

2. The general investment-savings identity: i=s+(t-g)+(kr -nx)=sp+sg+sf, where sp=s represents private savings, sg=t-g (ignoring domestic transfer payments tr) means ** savings, sf=kr -nx, which represents foreign savings in the country, and kr represents the transfer payment from domestic residents to foreign countries;

3. Important functions: consumption functions y= +y and y= +yd, where yd=y-t+tr, t represents a quantitative tax; investment function i=e-dr import function m=m0+ y;

4. Three-sector economy: the expenditure expression of equilibrium national income: y=c+i+g; is equation: y=( e+g- t+ t r -dr) or r= -y+ lm;

5. Macroeconomic policy effect: the effect of fiscal policy (taking Sun Infiltration 0 as an example) δy=0 kco 1δg, when fully effective: δy=δm;

6. The derivative deposit multiplier k:k represents the multiplier cherry oak relationship between all current derivative deposits d and the original deposit r: d=kr;

Completely incomprehensible.

The list of macroeconomic formulas is as follows:

1. The expenditure expression of the GDP of the general four-sector economy: GDP = C + i + G + (x-m), X - M = nx is called net exports;

2. The general investment-savings identity: i=s+ (t-g ) kr -nx ) sp+sg+sf where sp=s represents private savings, sg=t-g (ignoring domestic transfers tr) represents ** savings, sf=kr -nx represents foreign savings in the country, kr represents the transfer payments from domestic residents to foreign countries;

3. Important functions: consumption functions y= +y and y= +yd, where yd=y-t+tr, t represents a quantitative tax; investment function i=e-dr import function m=m0+ y; <

4. Three-sector economy: the expenditure expression of equilibrium national income: y=c+i+g; is equation: y=( e+g- t+ t r -dr) or r= -y+ lm;

5. Macroeconomic policy effect: fiscal policy effect (taking 0 as an example) δ y=0 kco 1 δ g, when fully effective: δ y= δm;

6. Derivative deposit multiplier k: k represents the multiplication relationship between all demand derivative deposits d and the original deposit r: d=kr;

7. The money creation multiplier k and m represent the nominal money, and the multiplication relationship between the supply m and the base money (also called high-energy money) h: m=kmh, h=r+cu=rd+re+cu. In the public form:

RD is the statutory reserve ratio and RE is the excess reserve ratio, which are the ratio of the statutory reserve R, the excess quasi-reserve RE and the cash CU to the total derivative deposit D, respectively.

Macroeconomics.

Macroeconomics studies the various phenomena in the economy that arise from the changes in aggregates, and the key variable is the national income, so the theory of national income determination is the central theory of macroeconomics. Focusing on this central theory, macroeconomics also studies the equilibrium between aggregate demand and aggregate supply, the relationship between unemployment and inflation, the problem of economic cycle and economic growth, and how to formulate and implement macroeconomic policies.
