If you are a freshman in an undergraduate or junior college, I think the answer 1, 3, 5, 6 is enough.
This question is not a short answer, is it? Anyway, I have a lot to answer myself. Because the cross elasticity coefficient of demand = percentage change of demand/percentage change of related commodity prices. The trading volume of a commodity is positively related to the trading volume of its supporting products. As we all know, rising commodity prices will lead to a decline in trading volume. For example, the price of a kind of beef has increased by +25%, so the demand for this kind of beef has also decreased, which has also led to a decrease in the demand for celery used for frying beef. Suppose that the demand for beef is reduced by-10% and the demand for celery is reduced by -8%. At this time, the demand cross elasticity of celery as a supplementary product of beef is (. 0。 Substitutes are the opposite of complementary products. When the price of beef rises by +25% (the percentage change of related commodity prices), many people stop buying beef and buy pork instead, so the demand for pork rises by +20% (the percentage change of demand). At this time, the demand cross elasticity of pork as a beef substitute is (+20%/+25%), so Ec > 0.
The basic feature of monopoly market is that a person or an enterprise controls the whole market supply of a product. The basic reasons for its formation can be summed up in the following six points:
(1) production development trend;
(2) the requirements of economies of scale;
(3) Requirements for the development of natural monopoly industries;
(4) the need to protect patents;
(5) Natural restrictions on entry;
(6) legal restrictions on entry.
If you want too much, the simple answer is-in order to establish and maintain a legal or economic barrier, so as to prevent other enterprises from entering the market and create and consolidate the monopoly position of monopoly enterprises.
Opportunity cost: In a scarce world, choosing one thing means giving up another. The opportunity cost of choice is the value of the corresponding abandoned goods or services. The simplest example is that you review your lessons. If you decide to spend two hours reviewing economics, you will give up the opportunity to review other subjects such as mathematics and English.
I do it myself, and I review it myself. Finally, I wish LZ exam success!
