I would be grateful to all the prawns and experts who would like to tell me a few examples of microe

For example, after the oil is ****, the price level will also be **, and the cost of transportation **will also **, and then it is easy to have inflation.

Modern Western economics divides economic principles or economic theories, that is, the entire content of the body of knowledge related to economic problems, into two major components or branches, namely microeconomics and macroeconomics.

Research content: Microeconomics includes a wide range of contents, including equilibrium theory, consumer behavior theory, producer behavior theory (including production theory, cost theory and market equilibrium theory), distribution theory, general equilibrium theory and welfare economics, market failure and microeconomic policy.

The research direction of microeconomics is the study of the economic behavior of individuals in the market, that is, the economic behavior of a single household, a single manufacturer and a single market, as well as the corresponding economic variables.

The market that the company faces is a perfectly competitive market in this case, and the recipient of **, so his marginal return MR is the market**. Profit maximization requires that our marginal cost mc and marginal benefit mr be equal. Assuming that the chip is represented by x1, its ** is W1, and since the ** of other elements will not change, in any case, PMP(x1,x2)=W1 is reasonable.

The raw material market is an oligopoly market, and the reduction of their products will inevitably lead to a rise in W1 to W1*. Since p is constant, then mp(x1,x2) in the above equation must go up, otherwise it will lose money.

Probably the first thing that comes to mind is to reduce x1 to make mp(x1,x2)**. But we need to know that the company's original intention in the beginning was to recruit employees, that is, to expand his production, because they are growing very fast. This shows that in the long run, they are far from reaching the optimal scale, and the long-term average cost is clearly not minimum.

The short-term average cost curve SAC is to the left of the LAC optimum. (Personally, I think this is very important, and if we are at this scale, it is natural to reduce the product and reduce the MC.) That is, reduce x1 and not recruit employees.

But we can also reduce the marginal cost of the product by scaling up. The reduction here refers to the time when the size is the same. The absolute value of the average cost and the marginal cost is inevitable due to the growth of W1.

And if you don't change, the increase of MC, SAC, LAC is the same: x1 w1 y. Therefore, in terms of scale decision, it is still necessary to expand the original production scale x2 to x2*.

And in this way, the marginal cost of the product is reduced to achieve the same as the original MR. The same is true for pmp(x1,x2*)=w1*.

So what they might discuss is: Since raw materials** are about to rise, funding will be more tight than before, and will take into account the cost of continuing to double the expansion. Whether it is a change in the number of people or a change in treatment must be analyzed in detail. I don't think the strategy of expanding enrollment will change.

Since I am short on time, I will briefly state my opinion. Since Samsung and Hyundai Electronics plan to suspend the production of memory chips next week, and its market share is 30% of the world, this means that the supply of chips will decrease, and if the market demand remains unchanged, the principle of supply and demand will lead to an increase in chips. This can be analyzed by the micro supply and demand curve, the supply curve moves to the left, and the demand curve remains unchanged, then the ** rises.

In this way, according to the principle of profit maximization pursued by the manufacturer, the production is arranged, and whether to expand the scale depends on whether the manufacturer's increased costs (including workers' wages and raw materials**) can bring greater profits if the manufacturer expands the scale. Sam and the HR director probably mainly discussed the cost of recruiting workers, the sales situation in the market, and then the profit of the manufacturer, calculating the optimal number of workers, and then deciding whether to expand.

First of all, Sam's product market is completely competitive, and he should be facing a group of non-competitive market manufacturers in the factor market (chips).

In the future, the supply of chips will decline, so the production factors are rising, and the product market is completely competitive, Sam is just a recipient, he has no way to control, improve the marginal return, therefore, when the factor rises, triggering the marginal cost to rise, the average cost of production is already in the right half of the average cost curve, the scale of return is decreasing, at this time Sam expands the number of employees, increasing the scale of production will lead to the marginal cost is higher than the marginal benefit, unreasonable.

So there is no need to expand the enrollment.

If the demand curve is a positive hyperbola, then the decline in goods** will cause the total amount of money spent by buyers on goods (answer: c).

a.Increase. b.Decrease. c.No change. d.All of the above are possible.

Analysis: The demand for a positive hyperbola indicates that the elasticity of the commodity is the unit elasticity, that is to say, the change of the commodity changes in proportion to the demand, so the total cost is constant, and this commodity generally does not exist in reality, which is a theoretical situation.

Edible oil is a necessity of life, according to the current living standard of the people, the vast majority of people will not significantly reduce consumption because of edible oil, nor will they easily turn to seek alternatives. The substitutes are: 1. Animal oil, mainly lard, but pork is also rising, and oil refining and preservation are more troublesome, easy to cause obesity, so it will not be replaced; 2. Miscellaneous oil sold in non-supermarkets may have advantages, but it is very likely to be gutter oil, which is not guaranteed to be safe to eat, and will not be replaced.

Therefore, it can be approximated that the demand for edible oil is completely inelastic, although ** has increased by 10%-30%, but the demand (i.e. supermarket sales) will not decline significantly. The above analysis may not be the same as what your teacher thinks, but economics is like this, and what is reasonable is correct.

In the short term, capital remains the same, and labor input changes.

aq=q/l=a bk/l;

mq=dq/dl=a;

In the long run, both capital and labor are variable, and there is a certain optimal ratio, assuming that the investment of the enterprise is H, the wage rate is W, and the capital rent rate is R, then H=Wl Rk; and q=al bk; Then construct a Lagrangian function to solve the optimal configuration g(l,k,c)=al bk c(wl rk-h);

dg/dl=0;

dg/dk=0;

dg/dc=0;When the configuration is optimal, the optimal yield is achieved. At this time, there is no simple average yield, but it is found on the basis of one unchanged, which is meaningless, but the MPL and MPK that exist at this time are meaningful, and they correspond to partial derivatives respectively.

The average output is the ratio of total output to labor, while the marginal output is the derivative of labor from the production function.
