measuring profitability Alpesh Paleja, chief economist at CBI, said: "although sales have grown in the past few months, the basic trading conditions for retailers remain difficult. We expect that the pressures on households to actually pay will continue for a while, so retailers still face challenges.

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 truth about foreclosures is That NO ONE wants one. You, the homeowner, obviously don't want to loose your own home to a foreclosure. The bank actually does not desire to foreclose. The bank will not have anything to gain by foreclosing on your own home. As a result of foreclosed the bank finds itself which has a home it does not want, a property it may ought to engage a "trash-out" plan to clean, a property it must sell. Even when the lending company does sell a foreclosed home it might loose funds on the sale of the home. About the only person who benefits from a foreclosure will be the "trash-out" service. Economic profits in perfect competition and monopolistic competition market has a special purpose, a positive profit can attract more enterprises to enter the market, increasing competition and push the market equilibrium price low, exclude some enterprises lack of competitiveness in the market, to achieve long-term equilibrium; On the contrary, negative economic profit can eliminate some of the original enterprises in the market, because the supply is reduced, the market equilibrium price will be pushed up, and the long-term equilibrium will be achieved. The result of the two cases is that economic profits disappear from each manufacturer and the manufacturer's total income is at the lowest point of average cost.
