Cosmology studies the origin and evolution of the universe. From the Big Bang to the present, and also to the future. In cosmology one works in the scientific study, on a large scale, of the properties of the universe as a whole. It is not an ordinary task. Trying to find answers to the destiny of the universe, or to its origin, are not, much less, minor issues.
b. hot during the day and warm at night
c. cool during the day and very cold at night
d. they depend upon the type of desert and its location
B)Unemployment
C)Aggregate Supply
D)Tax Revenues
The correct answer is D.
The Laffer Curve represents the relationship between the tax rate and the total tax revenues collected by the economic authorities. It illustrates the incidence of the taxable income elasticity, the sensitiveness of the income earned by the economic agents on which the tax is applied, to variations in the tax rate.
A laffer curve is represented in the graph attached. Tax collection is 0 for 0% and 100% rates. Between these two values, the function will have an increasing section, a maximum and a decreasing section. Its maximum consitutes the tax rate that maximizes the total tax collection.
The Laffer Curve depicts that changes in the tax rate have an impact on tax revenues. It indicates that there's an optimal tax rate that maximizes tax revenue, as both 0% and 100% tax rates would result in no revenue.
The Laffer Curve is a theory in economics that suggests there is an optimal tax rate which maximizes tax revenue. The curve predicts the effect of changes in the tax rate on tax revenues. It suggests that increase in the tax rate beyond a certain point will be counterproductive for raising further tax revenue.
For Example, If the tax rate is 0%, the government would earn no tax revenue. Similarly, if the tax rate is 100%, the government would also earn no tax revenue since there would be no incentive to work. Therefore, the Laffer Curve suggests that there is an optimal tax rate between 0% and 100% which will generate maximum tax revenue for the government.
