Chapter 1
Short Answer 1. Provide a definition of development economics. Justify your choice carefully. Answer: See the section in Chapter 1 entitled, “The Nature of Development Economics,” on Pages 9–10 for some ideas about how you might answer this question. You should in some way say that development economics is more than just growth in GDP. 2. In what way is development economics greater in scope than traditional economics? Answer: Development economics must encompass the study of institutional, political, and social as well as economic mechanisms for modernizing an economy while eliminating absolute poverty and transforming states of mind as well as physical conditions. More details found in the chapter. 3.
What do you think are the most serious obstacles to further progress in the developing world? Answer: The main point here is to ensure that you are thinking carefully about the issues raised in the text. You may also wish to draw from the critical questions on Pages 10–12.
4.
Why are women often referred to as playing a central role in economic development? Answer: An answer should include how women can influence whether or not the next generation will be impoverished through their role of childrearing based on the resources they bring to this task and the values they pass to their children. Another key point that should be mentioned is that empirically, women tend to allocate a higher percentage of the income under their own control to the family and children than men.

Sample Questions Short Answer 1. Explain how low levels of living can turn into a vicious cycle in developing countries. Answer: See the section on low levels of living in the chapter. 2.
Carefully explain some of the similar problems faced by otherwise diverse countries in Africa, Asia, and Latin America. Answer: This calls for you to summarize some of the main points listed in page 40.
3.
What are some of the main ways in which the economies of developing countries differ from one another? Answer: See the discussion in page 56 – 71; Diversity within commonality.
4. Explain why purchasing power parity measures of income levels tend to show a smaller difference between poor and rich countries. Answer: PPP measures show the number of units of developing country currency required to purchase a basket of goods and services in the developing country market that costs one dollar in the U.S. Prices for most services tend to be much cheaper in developing countries than in the U.S. 5.What are the three main indicators that make up the Human Development Index? Answer: Life expectancy, educational attainment, GDP per capita measured in PPP terms. 6. What are the three major components of economic growth? Answer: Capital accumulation, labor force growth, and technological progress.
7. Explain the lingering effects of colonialism and how it is still playing a role in hindering economic development in the developing world. Answer: Answers should be based on the points covered in the section on the colonial impact as well as in lecture. 12. The 2003 Human Development Report reported that the HDI of Botswana was 0.614 (and its rank was 125) and that of the Philippines was 0.751 (and its rank was 85). Botswana’s per capita income (in PPP dollars) was 7,820 and that of the Philippines was 3,840. Comment and explain. Answer: Students should discuss the difference between economic growth (per capita income) and economic development by discussing the components of the HDI.

Sample Questions Short Answer
1.
Describe one important criticism of Rostow’s stages of economic growth theory. Answer: The stages are only necessary and not sufficient conditions, savings is too aggregate a measure, the theory does not take into account the constraints of the international economic order, and there are counter examples such as Argentina.
2.
Assume a closed economy, perfectly elastic labor supply, and linear technology. Suppose the incremental capitaloutput ratio (ICOR) is 3, the depreciation rate is 3%, and the gross savings rate is 10%. Use the HarrodDomar growth equation to determine the rate of growth. What would the gross savings rate have to be to achieve 5% growth? Assuming a perfectly elastic labor supply, state one criticism of this model from an exogenous growth theory viewpoint and another criticism of this model from an endogenous growth theory viewpoint. Answer: . Answer: growth rate of 0.003, that is 0.3%, and 0.24, or 24% savings rate. Exogenous: does not allow factor substitution; endogenous: does not address sources of productivity growth, or the savings decision.
3.
What are the key assumptions of the Lewis model that give rise to its conclusions? How would the theory’s conclusions differ if these assumptions do not hold? Answer: The answer should include the existence of surplus labor in the rural sector that guarantees an infinitely elastic labor supply in industry until the surplus is exhausted and a propensity to save by industrialists equal to one. The lack of rural surplus labor (and infinite labor supply) would imply that when industrialists reinvest their profits there is no guarantee that their surplus increases. A low marginal propensity to save by industrialists puts a break on the labor transfer process.
4.
During the past decade, India has invested about 22% of its GDP while China’s investment rate has been double that of India’s. India’s annual growth rate has been about 6% while that of China has been about 9%. What conclusions can you draw? Answer: Students are asked to relate investment rates to the rate of economic growth through the HarrodDomar model. The students should calculate the ICOR for the two countries and note that India’s ICOR (about 3.67) is lower than China’s (about 5).
5. Use the handout on Neoclassical growth model to show that without technological progress an economy will always converge to its steady state where per capita output and income remains constant.

Chapter 4
Sample Questions Short Answer 1. What three factors distinguish models of endogenous growth from their neoclassical counterparts? Answer: There are increasing returns to capital investment (as opposed to decreasing), there are increasing returns to scale (as opposed to constant), and externality effects are included. 2. Explain what is meant by the term coordination failure and provide an example. Answer: This is a state of affairs in which agents are unable to coordinate their efforts, and hence end up in an equilibrium that leaves them worse off than they would be if they were able to coordinate. There are several examples offered in the text, or the students may come up with their own. 3. Show in a diagram an Scurve and a 45degree line. Are all three points of intersection stable equilibrium points? Explain. Answer: Explained in the text. Figure 4.1
4. Explain how the government can help the economy avoid a coordination failure. Answer: Discussed in the chapter. 5. Is a coordination failure a type of market failure? Explain. Answer: Yes, because an equilibrium can be reached that is not the true social equilibrium. 6. Explain the basic idea behind the Big Push model? Answer: Briefly explain the idea behind Figure 4.2. 7. How can the Oring theory help explain the existence of a lowlevel equilibrium that an economy may find itself in? Answer: Explained on Page 18283: Implications of Oring theory.
