Some people think capitalism is wholly bad for the environment as it is based on consuming scarce resources. They want less consumption and greater reliance on renewable resources. They oppose free trade because they favor self-sufficiency (autarky), or at least so-called fair trade, and because they believe it encourages poorer countries to destroy their natural resources in order to get rich quick. Although few professional economists would share these views, in recent years many attempts have been made to incorporate environmental concerns within mainstream economics. The traditional measure of GDP incorporates only those things that are paid for; this may include things that reduce the overall quality of life, including harming the environment. For instance, cleaning up an oil spill will increase GDP if people are paid for the clean-up. Attempts have been made to devise an alternative environmentally friendly measure of national income, but so far progress has been limited. At the very least, traditional economists increasingly agree that maximizing GDP growth does not necessarily equal maximizing social welfare. Much of the damage done to the environment may be a result of externalities. An externality can arise when people engaged in economic activity do not have to take into account the full costs of what they are doing. For instance, car drivers do not have to bear the full cost of making their contribution to global warming, even though their actions may one day impose a huge financial burden on society. One way to reduce externalities is to tax them, say, through a fuel tax. Another is prohibition, say, limiting car drivers to one gallon of fuel per week. This could result in black markets, however. Allowing trade in pollution rights may encourage “efficient pollution”, with the pollution permits ending up in the hands of those for which pollution has the greatest economic upside. As this would still allow some environmental destruction, it might be unpopular with extreme greens. There may be a case for international eco markets. For instance, people in rich countries might pay people in poor countries to stop doing activities that do environmental damage outside the poor countries, or that rich people disapprove of, such as chopping down the rain forests. Choices on environmental policy, notably on measures to reduce the threat of global warming, involve costs today with benefits delayed until the distant future. How are these choices to be made? Traditional cost-benefit analysis does not help much. In measuring costs and benefits in the far distant future, two main things seem to intervene and spoil the conventional calculations. One is uncertainty. We know nothing about what the state of the world will be in 2200. The other is how much people today are willing to pay in order to raise the welfare of others who are so remote that they can barely be imagined, yet who seem likely to be much better off materially than people today. Some economists take the view that the welfare of each future generation should be given the same weight in the analysis as the welfare of today’s. This implies that a much lower discount rate should be used than the one appropriate for short-term projects. Another option is to use a high discount rate for costs and benefits arising during the first 30 or so years, then a lower rate or rates for more distant periods. Many studies by economists and psychologists have found that people do in fact discount the distant future at lower rates than they apply to the near future.

In a word, all that was wrong with American capitalism at the start of the 21st century. Until late 2001, Enron, an energy company turned financial powerhouse based in Houston, Texas, had been one of the most admired firms in the United States and the world. It was praised for everything from pioneering energy trading via the internet to its innovative corporate culture and its system of employment evaluation by peer review, which resulted in those that were not rated by their peers being fired. However, revelations of accounting fraud by the firm led to its bankruptcy, prompting what was widely described as a crisis of confidence in American capitalism. This, as well as further scandals involving accounting fraud (WorldCom) and other dubious practices (many by Wall Street firms), resulted in efforts to reform corporate governance, the legal liability of company bosses, accounting, Wall Street research and regulation.

People generally spend a smaller share of their budget on food as their income rises. Ernst Engel, a Russian statistician, first made this observation in 1857. The reason is that food is a necessity, which poor people have to buy. As people get richer they can afford better-quality food, so their food spending may increase, but they can also afford luxuries beyond the budgets of poor people. Hence the share of food in total spending falls as incomes grow

At the heart of economic theory is homo economicus, the economist’s model of human behavior. In traditional classical economics and in Neo-classical economics it was assumed that people acted in their own self-interest. Adam Smith argued that society was made better off by everybody pursuing their selfish interests through the workings of the invisible hand. However, in recent years, mainstream economists have tried to include a broader range of human motivations in their models. There have been attempts to model altruism and charity. Behavioral economics has drawn on psychological insights into human behavior to explain economic phenomena.

Mathematics and sophisticated computing applied to economics. Econometricians crunch data in search of economic relationships that have statistical significance. Sometimes this is done to test a theory; at other times the computers churn the numbers until they come up with an interesting result. Some economists are fierce critics of theory-free econometrics.

Not putting all your eggs in one basket. Investors are encouraged to do this by modern portfolio theory, as holding several different shares and other assets helps to reduce risk. At the sharp end of business, however, diversification is somewhat out of fashion. Economic studies of diversifying corporate mergers have found that these often hurt the shareholders of the acquiring firm; by contrast, diversified firms that have sold off non-core businesses have typically made their shareholders much better off.

The more you have, the smaller is the extra benefit you get from having even more; also known as diseconomies of scale (see economies of scale). For instance, when workers have a lot of capital giving them a little more may not increase their productivity anywhere near as much as would giving the same amount to workers who currently have little or no capital. This underpins the catch-up effect, whereby there is (supposedly) convergence between the rates of growth of developing countries and developed ones. In the new economy, some economists argue, capital may not suffer from diminishing returns, or at least the amount of diminishing will be much smaller. There may even be ever increasing returns.
