- The right sees large deadweight losses associated with taxation and, therefore, is worried about the growth of government as a share in the economy. The left sees smaller elasticities of supply and demand and, therefore, is less worried about the distortionary effect of taxes.
- The right sees externalities as an occasional market failure that calls for government intervention, but sees this as relatively rare exception to the general rule that markets lead to efficient allocations. The left sees externalities as more pervasive.
- The right sees competition as a pervasive feature of the economy and market power as typically limited both in magnitude and duration. The left sees large corporations with substantial degrees of monopoly power that need to be checked by active antitrust policy.
- The right sees people as largely rational, doing the best the can given the constraints they face. The left sees people making systematic errors and believe that it is the government role’s to protect people from their own mistakes.
- The right sees government as a terribly inefficient mechanism for allocating resources, subject to special-interest politics at best and rampant corruption at worst. The left sees government as the main institution that can counterbalance the effects of the all-too-powerful marketplace.
- There is one last issue that divides the right and the left—perhaps the most important one. That concerns the issue of income distribution. Is the market-based distribution of income fair or unfair, and if unfair, what should the government do about it? That is such a big topic that I will devote the entire next lecture to it.
I strongly disagree with #2. See my post from yesterday. I think both parties benefit equally from market intervention. While historically, a “conservative” believes in a non-interventionist theory of market control, I do not think politicians generally follow this rule. I think they advocate intervention when it benefits them politically or personally – regardless of theory.
Curious to hear more feedback.
