B. The amount of deadweight loss is $20,000 after the tax.
C. Total revenue earned by light bulb producers increases after the tax.
D. The total tax revenue collected by the government is $30,000 per month.
E. Consumers and producers are sharing an equal percentage of the tax burden.

Answer 1

Answer:

A. Total expenditure on light bulb increases after the tax.

Explanation:

The government has imposed tax on the light bulb production and the new price after the tax is $14. The price before the tax was $12 and the marginal cost before tax was $9. There was a profit of $3 for the producers of the light bulb. The tax burden is shifted to the consumers of the bulb since the marginal price after tax is $12. Total expense for the production of bulb has increased due to tax.
