Some struggle with medical issues - like insomnia - that make sleep hard. But for many of us, the quantity and quality of sleep come down to a matter of choice. Still, only a few enterprising economists have looked closely at this, and generally, those have assumed that we choose our hours of sleep optimally.
The prevailing ideology of the modern west - which is political economy - is in the doghouse. Having failed to notice atmospheric pollution, the economists then frightened themselves with the sort of financial crisis they said they had abolished.
For me, geopolitical issues are becoming more important, because how can you understand economy if you don't understand geopolitics? People think economists just deal with spreadsheets and charts. That's a narrow-minded caricature.
How is it that, in the face of overwhelming scientific evidence, there are still some who would deny the dangers of climate change? Not surprisingly, the loudest voices are not scientific, and it is remarkable how many economists, lawyers, journalists and politicians set themselves up as experts on the science.
Although most Americans apparently loathe inflation, Yale economists have argued that a little inflation may be necessary to grease the wheels of the labor market and enable efficiency-enhancing changes in relative pay to occur without requiring nominal wage cuts by workers.
The biggest tab the public picks up for fossil fuels has to do with what economists call 'external costs,' like the health effects of air and water pollution.
But if, if you take a look at what would have happened, I mean, do we need to see soup lines down the street to figure out what would have happened? We avoided - and all economists will tell you that millions of jobs were saved because of the Recovery Act, and we avoided a second Great Depression. That, that is a reality.
Ask five economists and you'll get five different answers - six if one went to Harvard.
Even as I pursued a doctorate in the history of ideas in my native Denmark, I realized I had neither the encyclopedic training nor the passion for cool logic - not to mention the nerve - to follow in the footsteps of classical liberal philosophers and economists such as Robert Nozick, Friedrich Hayek, and Milton Friedman.
Economics is extremely useful as a form of employment for economists.
