H3. Empirical evidence has highlighted noticeable income convergence across difference regions in the US. It has been discussed in many classical studies, including Barro and Salai-Martin (1991). However, researchers also noticed some different pattern in reality. For example, there are two cities in central Arkansas. They are 40 miles apart from each other next to an inter-state highway. The two cities were similar in several aspects, for example infrastructure, demographics and industries until the 1980s. For example, both cities had about 5,000 total population and roughly $10,000 of average household income in the mid-1970s. After 40 years, one city still has about 5,000 people and with $28,000 average household income. The other city, however, has grown into a decent metro-area with about 30,000 residents and $50,000 average household income. 1) From the story above, can you find any evidence to support or invalidate the Solow growth model, which is the core of modern economic…
(SW 7.10) Show that the two alternative formulas below for the homoscedasticity-only F-statistic are equivalent. F = (SSRrestricted − SSRunrestricted) /q SSRunrestricted/ (n − kunrestricted − 1) (equation 7.13 in SW) F = R2 unrestricted − R2 restricted /q (1 − R2 unrestricted) / (n − kunrestricted − 1) (equation 7.14 in SW)
In 2009 the Organization for Economic Cooperation andDevelopment (OECD) conducted a study of 34 membercountries called the Programme for International StudentAssessment (PISA). The OECD looked at reading scores among 15-year-olds in each country as well as the stu-dents’ socioeconomic backgrounds. PISA reported that higher socioeconomic status was associated with higher reading scores, with their socioeconomic index explain-ing 14% of the variability in reading scores. (Source: Sahlberg, Pasi, “A Model Lesson: FinlandShows Us What Equal Opportunity Looks Like,”American Educator Spring 2012: 25.)Which of the following can be correctly concluded fromthis information?A) For every additional point in the mean reading scorein an OECD country, the PISA socioeconomic indexis expected to increase by 14% on average.B) For every additional one percent increase in the PISAsocioeconomic index, the mean reading score isexpected to increase by 14% on average.C) If the U.S. government wants to…

Bolsa-Familia is a social welfare program in Brazil. In this program, poor families are given cash payments conditional on their children's school attendance. Suppose you want to con- duct a study on the impact of Bolsa-Familia on future earnings. Your treatment group is children on the program, and your control group is chil- dren who aren't on the program but have similar family backgrounds. What is the problem with this method?
