…here are some ideas that I’ve seen in most of the introductory economics textbooks I’ve looked at:
- Governments (typically through central banks) need to manage the demand level of national economies to prevent catastrophic recessions and mass unemployment.
- Absent carbon pricing, a market economy will massively overproduce greenhouse gases.
- Many industries, such as broadband Internet, are “natural monopolies” where an unregulated market will lead to higher prices and less investment than is socially optimal.
- Due to asymmetrical information, consumers in a market economy will be unable to bargain effectively with doctors and other providers of health care services.
- Due to adverse selection, consumers in a market economy will be unable to effectively insure themselves against health risks.
- Due to the declining marginal utility of money, taking $100 from a rich person and giving it to a poor one will increase human welfare.
- Increasing the number of immigrants, raising taxes on the rich, and making Social Security benefits more generous will make almost everyone better off.
I could go on like this. But suffice it to say that one of the main reasons that so many economists are Democrats is that on a whole lot of issues the basic econ 101 view supports the liberal position.
