b) 2 issues addressed by William lewis in the Power of Productivity
1) -undistorted competition in the product market
- in order to have a healthy economy, the most productive firms should win
- more productive firms expand and take market shares,overall productivity of the country increases.
- less productive firms go out of business or increase productivity.
-Competition makes productivity increase,
-less intense competition, slower productivity growth.
-Market distortions explain difference between GDP per capita of US and other rich countries
2)-Innovations, allow innovators to make more profits, invest more, take market share away from
competitors, profits will return to normal after a period, in which the level of productivity is at a higher
level
3)-Too much government influence restricts productivity growth
-Protection of less productive firms is a regular occurrence in industrial countries such as France,
Germany and Japan.
-best practice retailers are prevented from expanding as fast as they can thus, productivity growth is
slower.

-Too much government influence has proved that old factories and companies are protected against
bankruptcy while they keep productivity at a minimum.
Unsuccessful owners be allowed to fail and workers have to find new jobs.
