Government policies have a major role to play in encouraging (or deterring) economic growth. Economic policies that lead to economic growth include:
Investing in infrastructure:
Infrastructure, such as highways or bridges, is tangible capital available to all. Governments are increasing their capital stock in the country by investing in infrastructure.
Productivity and labor participation strategies :

Answer:
Christiaan Huygens
Explanation:
Christiaan Huygens was a Dutch physicist with many credits and inventions some of which is the pendulum clock and production of many telescopes. He is also credited as the father of theoretical physics being the first to make use of formula in physics.

Explanation:
A concentration ratio is the ratio of the combined market shares percentage held by the largest specified number of firms, compared to the given market size. The concentration ratio ranges from 0% to 100%. If the concentration ratio of an industry ranges from 0% to 50%, that industry is said to be perfectly competitive if the top 5 firms have a concentration ratio of 60% or more, oligopoly is said to occur, and if the competition ratio of one company is 100% it shows monopoly.
In our example, the concentration of the largest four market segments are:
35%, 30%, 15% and 10%
Therefore, the four firm market concentration ratio = 35 + 30 + 15 + 10 = 90
