+ 75% High-school dropout rates and performance at graduation by score at entrance exam Grade at entrance exam Percent that dropped out from Score on the final exam at - cutoff score for admission high school end of high school 50 0 0 62 elite schools Admitted in 0.53 0.45 51.0 0.50 4810 0 30 0.20 Not admitted in elite schools 42 5 0.25 0.17 45.0 011 Source: Adapted from the analysis of de lanwry, Dustan, Sadoulet (b) Draw two regression lines (Excel commands: Chart, Add linear trend line in Excel, Display equation on graph) separately for the points above the cutoff score (i.e., for those admitted to the elite schools) and for those below the cutoff score (i.e., not admitted to elite schools). Measure the "discontinuity" that you observe at the limit at the point where students were just admitted, i.e., the vertical difference in the two trend lines evaluated at the cutoff. (c) Explain why this may be a credible measure of the causal impact of attending an elite school on the risk of not graduating from high school. In what sense is it a "local" treatment effect? What are some of the factors that might lead to a different impact for students with entrance exam scores far above the cutoff? (d) Repeat the analysis as in question (1b) using the score on the final exam at the end of high school as the dependent variable. Report the impact of attending an elite school on final exam scores at the end of high school. (e) Discuss the trade-off faced by students upon deciding whether to attend an elite school. (f) What is the condition for the validity of this method, and what does this imply about the characteristics of individuals around the cutoff? Discuss what data would you need to have to test that this condition applies and what analysis would you do to support it. Report your results using two graphs: one for the graduation rate and the other for the score on the final exam at the end of high school.

B. Regarding compound interest, take the interest rate annually and determine the interest period yourself. (for example, every 3 months, every 50 days ....) Derive and answer a question regarding the calculation of the term (11) and interpret it. C. Derive a question that you will calculate future value (S) on compound interest. Also ﬁnd and interpret the "effective interest rate" of this example. D. In a question about internal discount, ﬁnd the calculation of the nominal value (S) and the cash value (Pi). (In this question, please take the interest annually and take the interest cycle as 4-month or 20-day, please resolve and comment.)
