Suppose the government imposes an $8-per-dvd tax on suppliers. at this tax amount, the equilibrium quantity of adult dvds is dvds, and the government collects $ in tax revenue. now calculate the government's tax revenue if it sets a tax of $0, $8, $16, $20, $24, $32, or $40 per dvd. (hint: to find the equilibrium quantity after the tax, adjust the "quantity" field until the tax wedge equals the value of the per-unit tax.) using the data you generate, plot a laffer curve by using the green points (triangle symbol) to plot total tax revenue at each of those tax levels.

The business cycle is the periodic but irregular up-and-down movement in economic activity, measured by fluctuations in real gross domestic product (gdp) and other macroeconomic variables. a business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. economists note, however, that complete business cycles vary in length. the duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations. but the term "business cycle" is still primarily associated with larger (industry-wide, regional, national, or even international) business trends.

The answer is b) market forces
