Frances O 'grady, chief secretary of the UK federation of industry and industry, said: "this suggests that brexit uncertainty has damaged the household budget. Work and living standards must be a priority in determining the best choice for brexit. The government should maintain a single market membership at the negotiating table. " 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. This refers to the industrial handicraft industry from the feudal society to the early stage of capitalism. In the 16th century to the 17th century, some western countries of the feudal social system to the system of capitalism, capitalist primitive accumulation is accelerated, deprived of farmers' land on a large scale, make cottage industry collapse, sharply to capitalism works system transformation. Industrial handicraft industry is the embryonic form of enterprise. The importance of gasoline was not recognized in the 19th century, when it was used in a great deal of kerosene. The oil refining then relied on simple distillation processes to separate the different components of the oil from the boiling point. The boiling point of the kerosene component is higher, and the use of safety when lighting lamps becomes the main product of crude oil refining, while gasoline and other components are often burned as fuel. By the mid - to late 19th century, the successful use of gasoline engines in 1886, in 1886, the gasoline engine was successfully used as a driving force, thus the importance of gasoline increased. But using distillation, only 20% of the gasoline can be extracted from crude oil. In 1911, the standard oil company have solved the problem of low gasoline yield, by William burton and Robert hamm forest thermal cracking process of the invention, the heavy quality heating gas oil cracking of light gasoline fractions, such as to overall improve the gasoline yield, thermal cracking process in 1913 won the patent license in the United States. The subsequent catalytic cracking process has further improved the gasoline yield and octane value. Xpoint fills the cost and cost gap between high speed and high cost DRAM and low cost NAND. Does this technology engulf DRAM and NAND markets? Customers who purchase a large number of Xpoint chip/drives may purchase fewer DRAM chips and NAND chips/drives. Another element of the market-tracking plan is determining the number of foreign exchange futures markets to track and the number of transactions to be traded within a certain period of time. Unlike stock investing or futures trading, forex currency trading doesn't need and contains a particular market. All trades are executed Over The Counter (OTC) through high-speed interconnected electronic networks. The banks have their own dealing rooms and many individual traders trades from other home on specific encrypted currency trading software platforms. These trading platforms are usually of two sides as online or broker-side trading platforms and direct access or trader-side trading platforms.
