US Economic Experts Panel

The Clark Center for Global Markets explores economists’ views on vital policy issues via our US and European Economic Experts Panels. We regularly poll over 80 economists on a range of timely and relevant topics. Panelists not only have the opportunity to respond to a poll’s statements, but an opportunity to comment and provide additional resources, if they wish. The Clark Center then shares the results with the public in a straightforward and concise format.

Please note that from September 2022, the language in our polls will use just two modifiers to refer to the size of an effect:

  • ‘Substantial’: when an effect is large enough that it would make a difference that matters for the behavior involved.
  • ‘Measurable’: when the direction of the effect is clear, but perhaps experts would differ as to whether it is substantial.

Market Share and Market Power

If a small number of firms have a large combined market share in a properly defined market, it is strong evidence that those firms have substantial market power.

Ride-Sharing Caps

Question A:

Capping the number of ride-sharing drivers as is being discussed in New York City, Chicago and London will make the average resident in that city worse off.

Question B:

To achieve a given level of congestion, it would be better to use taxes for driving that vary based on the level of congestion, rather than limiting the number of ride-sharing vehicles.

Central Banks and Productivity

Britain’s Labour party recently proposed giving the Bank of England a target of 3% annual labor productivity growth. Consider the following statement:
Central banks cannot significantly increase productivity growth over a ten year horizon, except perhaps by promoting macroeconomic stability.

The NCAA

This week's IGM Economic Experts Panel Statement:

NCAA Division I schools coordinate compensation for men’s basketball and football players (precluding actual pay and limiting non-monetary benefits), providing rents to member schools (which may be shared with others) at the expense of those players.
