1. The long-run cost function for LeAnn's telecommunication firm is: C(q)=0.03q². A local telecommunication tax of $0.01 has been implemented for each unit LeAnn sells. This implies the marginal cost function becomes: MC(q,t)=0.06q+t
   1. If LeAnn can sell all the units she produces at the market price of $0.70, calculate LeAnn's optimal output before and after the tax.
   2. What effect did the tax have on LeAnn's output level?
   3. How did LeAnn's profits change?

3. One

1. One of the basic principles of classical growth theory is that over time, levels of economic activity should converge in most countries and that we would enjoy equal levels of prosperity. While we view some evidence of convergence, we also observe the continuation of stark and deep levels of global inequality

1. In one small paragraph, use our production function analysis to explain why we might predict economic convergence.
2. In an additional paragraph, use our production function analysis to explain why we might not be experiencing convergence.
3. What country are you a citizen of (UNITED STATES)? Use the growth theory you have used in your previous answer to explain whether you are part of a country that is either:

1. Catching up to advanced capitalist countries,

2. Being caught up to by more rapidly growing countries, or

3. Still experiencing a big gap in living standards with no immediate prospects of catching up.

Briefly explain why the country you are a citizen of falls into the category you have chosen.

Why did Latin American countries in the latter half of the 19th century enter “neocolonial,” economically dependent relationships with European powers?

4. Suppose we have a market for coffee and pastries.

a. Graph the market (no need to give numbers for endpoints of the budget constraint) and show an optimal consumption bundle.

b. Suppose the price of coffee drops. Graph the new budget constraint.

c. Now, illustrate the INCOME and SUBSTITUTE effects of the price change and show the new optimum. Remember, you must draw the imaginary budget constraint and then find the tangency on the new budget constraint.

A large manufacturing company in Jubail is considering an electric power plant project in order to save on their electric power consumption by generating its own power supply. The company currently uses 552,000 kW of electric energy a year and pays an average of $3.05 per kwh. The construction of the power plant would require an initial cost of $1,600,000 now plus an additional $950,000 investment at the end of the first year. It is expected to be operational for 10 years with an estimated residual value of $160,000 at the end of the 11th year. Since the installation of the project would take about one year, the annual benefit (in terms of savings) as well as the annual costs would occur only starting at the end of the second year. At that time, the annual operation and maintenance cost is estimated at $750,000 and expected to increase by 5% annually until the end of its useful life. As the capacity of the power plant would be more than adequate what the company needed, the excess energy could be supplied to the neighboring establishments from the fifth year up to the end of the productive life of the project, thereby creating an additional income of $105,000 per year.
Suppose MARR=15%, evaluate this project proposal using all relevant and applicable project assessment tools and techniques. Based on the analysis results, write a detailed recommendation report explaining and justifying your decision whether the project proposal should be accepted or rejected.

An industry's inverse demand was P^D = 20 - 0.1Q and its inverse supply was P^S = 4 + 0.1Q.

1. Calculate the consumer surplus, producer surplus, government revenue and deadweight loss for taxes of $4, $8, $12 and $16 per unit sold.

2. Graph government revenue and deadweight loss as functions of these tax rates.

3. What tax maximizes government revenue?

Explain answers.

Your company is considering expanding by opening new representative offices in the European Union (EU). Nevertheless, the size of the investment is significant and top management wishes to have a clearer picture of the current and probably future economic status of the EU. Work out an executive summary describing the features you consider as crucial in making such a decision.
