In addition to the formal "perfect" in the new classical market concept, the new classical theory has not added new meaning to the classical theory. That is to say, under the new classical "perfect" mathematical model under the skin, it is still classical free laissez-faire order, "new" is "new" in the form. And the form of depth at the expense of perfect at the expense of the thoughts, general equilibrium model of fine arbitrarily abstract away the activities of the "personal pursuit to satisfy desires to promote social welfare" logic support. For a long time, the wine produced by this figure was mainly sold in the domestic market. But in recent years, the downturn in Brazil's domestic market has led to a shift in the direction of hong winemakers abroad. China, a big consumer of red wine, is a natural focus. Although Brazilian wines have a short time to enter China, the country's total exports to China reached nearly 200,000 bottles last year alone.

Once the starting point is established, the change in the price level can be attributed to rising, falling or maintaining the original state.

It is not obvious in some analyses, but it is important to note that economic profits include opportunity costs. The profit of an entrepreneur (normal profit) is usually positive, but economic profit can be either positive or negative (loss). That's why the opportunity cost is included: in a completely competitive market, when marginal cost equals marginal revenue, profit maximization or loss minimization conditions arise. If the market price is lower than the total average cost, which means that the economic profit is negative, the entrepreneur needs to compare the value of the loss and the average variable cost. If the business continues to operate, the negative economic profit must not be lower than the average variable cost, otherwise the entrepreneur would rather shut down the company than continue to take the loss.
