profit equation economics Although an enterprise's internal trade fair eliminates or reduces some of the market transaction costs, it also brings with it the specific transaction costs of the enterprise. The main reason for this defect is also the incompleteness of information. Specifically, first, there are various contractual relationships among enterprises, including contractual relationship between enterprises and workers, contractual relationship between enterprises and managers, etc. The enterprise should supervise the work of the workers and products that it employs, as well as the managers and other personnel, and induces them to work hard for the enterprise. So, companies are signing contracts and spending on oversight and incentives. Secondly, on the one hand, corporate decision makers often need to obtain information from subordinates. On the other hand, the decision-making information of the upper level of the enterprise should be realized by passing it to the subordinate. The information transmission of these two different directions will be distorted by the increase of subordination of enterprise scale, resulting in the loss of enterprise efficiency. Once again, the subordinate of the enterprise often conceals or passes the wrong information to the superior for selfish motives, so that the superior can make decisions that benefit the subordinate. Or, the subordinate's decision to the superior only passes or executes the part that is advantageous to oneself. These will result in the loss of enterprise efficiency. Thus, the expansion of enterprises is limited. According to coase's theory, the scale of the enterprise should be expanded to this point, that is at this point to increase the cost of an internal exchange cost equals the cost through the market exchange cost and so on. Although miolo is doing well in China, tiloni also talks about his worries. He believed that the greatest advantage of the Brazilian wine is cost-effective, but compared with wine importing "zero tariff" neighboring Chile, Brazil wines in the Chinese market at present stage, there is no big advantage to speak of. "Our biggest problem right now is the price," he said. "our wine is very competitive when it comes out of the factory." But Chile and China have zero tariff agreements on wine trade, and we don't, which makes our products much more expensive in China. However, I believe that this problem will be solved and the demand for wine in the Chinese market is very high. I believe that the future development of Brazilian wine in China should be good. Loading is the work load that is allocated to a work centre. For example, time might be lost while changing over from making one ingredient of another. If the machine in time breaks down, it will not be available. If there is machine reliability data available, this also needs to be taken into account. Sometimes the equipment could possibly be awaiting parts to reach or be 'idling' for a few other reason. Other losses could include an allowance for the device being run below its optimum speed as well as an allowance for that 'quality losses' or defects which the machine may produce. Of course, many of these losses must be small or non-existent in a well-managed operation. Finite loading is definitely an approach which only allocates work to a work up to and including set limit. This limit will be the estimate of capacity to the work centre (based on the times designed for loading). Infinite loading is surely an method of loading work which does not limit accepting work, but rather tries to cope with it. Until then, depositors had not even seen a rise. Interest rate, in the form of expression, refers to the ratio of the amount of interest to the total amount of borrowed capital in a certain period of time.  the interest rate is the interest level per unit time of the unit currency, indicating the interest rate. Economists have been looking for a theory that can fully explain the structure and change of interest rates. Interest rates are usually controlled by the central bank of the country and administered by the federal reserve board in the United States. Today, interest rates are one of the important tools for macroeconomic regulation.
