How do the right and left differ?



The conclusion of today’s ec 10 lecture:

In today’s lecture, I have discussed a number of reasons that right-leaning and left-leaning economists differ in their policy views, even though they share an intellectual framework for analysis. Here is a summary.

  • 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.

    Greg Manikiw on himself: “… a professor of economics at Harvard University, where I teach introductory economics (ec 10) among other courses.”
    Thanks to Michael Kruse for posting this up on his own exciting blog: Kruse Kronicle and that’s also a link to his excellent new series on “Living Simply in Abundance”.
