Economics, as it is often taught today, portrays us as homo economicus-someone who doesn't vote in presidential elections, doesn't return lost wallets, and doesn't leave tips when dining out of town. Julie Nelson reminds us that most people aren't really like that. She helps point the way to a richer, more descriptive way of thinking about economic life.

The most glaring deficiency in traditional economic models is that they completely ignore the role of context in evaluation.

Getting the economy back on its feet is properly viewed as an investment in future prosperity. When businesses and consumers confront attractive investment opportunities, often the only way to seize them is by borrowing. The same is true for government. Contrary to the pronouncements of critics of economic stimulus, these investments will not impoverish our grandchildren. Continuing to allow the economy to languish in recession is the surest way to impoverish them.

We've long known that firms can pay higher wages if they spend less on workplace safety enhancement. Libertarians ask, "If a worker is willing to accept higher wages in return for his agreement to exercise greater caution while performing his job, why should the government prevent him from making that choice?" It's a rhetorically powerful question, yet it overlooks the fact that the agreement in question will have adverse effects on others.

If top marginal income tax rates are set too high, they discourage productive economic activity. In the limit, a top marginal income tax rate of 100 percent would mean that taxpayers would gain nothing from working harder or investing more. In contrast, a higher top marginal rate on consumption would actually encourage savings and investment. A top marginal consumption tax rate of 100 percent would simply mean that if a wealthy family spent an extra dollar, it would also owe an additional dollar of tax.

When the economic pie grows larger, it's always possible for everyone to have a larger slice than before. So it's really in all of our interest to make the economic pie larger by eliminating waste whenever and wherever possible.
