The tax multiplier is -b [1-b(1-t)] and the expenditure multiplier is 1 [1-b(1-t)], both of which become smaller when t increases, regardless of the relationship between plus and minus signs. Of course, since the multiplier often comes down to the multiplier effect in the end, it is understandable to say that it is both smaller.

Net tax is the difference between ** tax and transfer payments, and the net tax multiplier can also be seen as a tax multiplier, which is numerically equal.

The less you consume, the greater the marginal propensity to consume, and the marginal propensity to consume decreases as income increases... It increases as it decreases.

muy==(1/2)[x^(1/2)]*a*y(-1/2)

mux/muy=8/py

8x+py*y=656

The equation of the demand curve for y is synapsion-specific.

1. y = [b/(a+b)]*m/py] = [b/(a+b)]*656/2]

2. x = [a/(a+b)]*m/px] = [a/(a+b)]*656/8]

Knowing the equation, substituting the cross-elasticity formula and the income elasticity formula leads to the second question.

When the py drops to 1 yuan, while keeping the original consumption level unchanged, it is equivalent to an increase in income (2-1) (y when py=2 yuan)=? Yuan, this is the biggest price he is willing to join. The same is the biggest cost of his membership in the other two cases.

As long as there is a maximum cost greater than 176, join the union. As for which right to choose, it depends on the utility.

For example, the original utility is u=xayb <==, and you can get it by substituting the demand curve equation of x y.

v = a} *b} (note, a denotes the power exponent).

It's best to write this thing on paper... It doesn't seem that complicated ...

After joining this club, the income m = 656 - 176 = 480

So, the functions of x y have changed...

50% buy xx = [a (a+b)]*m px] = [a (a+b)]*480 4].

y = [b/(a+b)]*m/py] = [b/(a+b)]*480/2]

> v = ..

50% Buy YX = [A (A+B)]*M Px] = [A (A+B)]*480 8].

y = [b/(a+b)]*m/py] = [b/(a+b)]*480/1]

> v = ..

75% buy x and y

x = [a/(a+b)]*m/px] = [a/(a+b)]*480/6]

y = [b/(a+b)]*m/py] = [b/(a+b)]*480/

> v = ..

Then the ratio with the original utility is larger, and then the largest utility is selected.

There is a conclusion

1. The salary will be the same. As.

If the wages of the aircraft manufacturing industry are higher than those of the automobile manufacturing industry, then it will lead to an increase in the labor supply of the aircraft manufacturing industry.

Workers who participate in training in the aircraft industry increase) and wages decrease. The supply of labor in the automobile manufacturing industry decreases, wages rise, and finally an equilibrium is reached, that is, the wages of the two industries are equal. If there is no change in other factors, the wage level will continue forever.

2.The import of automobiles will lead to a decrease in the labor demand of the automobile manufacturing industry, and the export of aircraft will lead to an increase in the labor demand of the aircraft manufacturing industry.

3. In the short term, due to the increase in labor demand in the aircraft manufacturing industry, the labor supply cannot be increased in the short term, resulting in an increase in the wage level. Wages in the auto manufacturing industry have fallen. In the long run, all factors of production can be adjusted, and workers can change industries by participating in new training.

4. The shortage of labor supply in one industry and the oversupply of another industry lead to the problem of unemployment.

a Wages in the two industries are comparable, and this process will continue until new variables are addedb After opening up to the international market, demand in the aircraft industry will increase and demand in the automotive industry will decreasec Equilibrium wages will rise in the short term and decrease in equilibrium wages in the long term.

d Result in a shortage of labour or overlabour.

The European debt crisis stems from the disunity of the monetary system and the fiscal system, and the global financial crisis is also the same.

Question: Why does the fiscal cliff issue lead to ******?

The analysis is as follows:

When the marginal utility of the XY commodity is compared to its ** identity, the utility is the largest MUX px=muy py, that is, the utility of the last dollar spent on the XY commodity is equal.

tu derives x,y respectively, mux=3y 2, muy=6xy, px=20, py=30, solves 3y=4x, then 20x 30y=540, simultaneous equations, solves x=9, y=12, tu=3*9*12 2
