On the basis of introducing marginal concepts and mathematical argumentation, neoclassical has established a formal "perfect" mathematical model for the neoclassical "laissez-faire order" : general equilibrium. The price is the most important independent variable in this model, which can also be called price mechanism. The process of achieving general equilibrium is also a process of social resources guiding the flow of prices, so the price mechanism regulates the allocation of social resources. In the American society of automotive engineers standards SAEJ 687 c for automobile is defined as: power driven by itself, with a driving device, can in a fixed orbit outside the road or on regional transport passenger and cargo or vehicle traction vehicles. Cars are divided into bicycles and trains according to the overall structure. Cycling is a basic form. 4 x 2, 6 x 4, 4 x 4 and 6 x 6 are used to represent the driving characteristics. The previous number represents the total number of wheels (double tire and still count a wheel), and the latter number indicates the number of driving wheels. If all wheels are driven wheels are called all-wheel drive vehicles. The train is made up of a tractor or a bicycle trailer or semi-trailer. Car generally can be divided into the following categories, according to the use cars, buses, freight cars (commonly known as the truck), off-road vehicle, traction motor, dump truck, special vehicles, semi-trailer and special semi-trailer. On November 11, 1997, the bank of England took a big step towards independence, politely revising the "banking law" of 1946 and reading it in the lower house. The bill passed legislation affirming that Gordon Brown, the Treasury secretary, freed government control from the central banking business. This is the hallmark of an institution that has been under the yoke of government for a century and a half. It symbolises how demand for central bank independence becomes conventional wisdom. Adam Smith began as a logical starting point for "the personal gratification of the activity of personal gratification," and the market was "laissez-faire". The activities of the government completely unable to intervene in the pursuit of personal wealth, also don't have to worry about the laissez-faire altogether will create chaos, "an invisible hand" will be taking the laissez-faire personal economic activities arranged in perfect order. In other words, Adam Smith's market concept focuses on limiting government interference in individual economic activities. The wealth of nations also spends a considerable amount of time attacking the mercantilist policies that interfere with individual economic activity and limit individual economic power (property rights). Later classical economists stuck to their laissez-faire views. The high yield p2p wealth management products know the above mentioned above, and also know that the domestic p2p financing market is not sound enough, so there is a certain risk in the p2p financing investment. How to choose investment platform, how to determine the security of P2P wealth management products, its complexity is also greatly increased. So be cautious as investors. “With the government-commissioned Taylor Review noting this abuse, we’re hopeful that 2018 will be the year of action on fair pay for agency workers.”
