Use the four-firm concentration ratio given in parentheses to determine which of the industries is most likely to be characterized as highly competitive.Group of answer choicesGame Consoles (98%)T-shirts (37%)Dry Cleaning (25%)Restaurants (45%)

The four-firm concentration ratio is a measure used to indicate the degree of competition in an industry. It is calculated by adding the market shares of the four largest firms in the industry. The higher the concentration ratio, the less competition there is in the industry.

Here are the four-firm concentration ratios for the given industries:

1. Game Consoles (98%)
2. T-shirts (37%)
3. Dry Cleaning (25%)
4. Restaurants (45%)

From these ratios, we can see that the Game Consoles industry has the highest concentration ratio at 98%. This means that the four largest firms in this industry control 98% of the market, indicating a high level of concentration and low level of competition.

On the other hand, the Dry Cleaning industry has the lowest concentration ratio at 25%, suggesting that this industry is the most competitive among the four. The four largest firms in the Dry Cleaning industry only control 25% of the market, leaving a large portion of the market to other firms.

Therefore, the Dry Cleaning industry is most likely to be characterized as highly competitive.
