To study the determinants of growth across the countries in the world, researchers have used country level observations averaged over long periods of time (e.g. averaged over 1960- 2000). Some of these studies have focused on the effect that inflation has on growth and found that although the effect is small for a given time period, it accumulates over time and therefore has an important negative effect. (a) Explain why the OLS estimator may be biased in this case. (b) Some authors have suggested using an index of the Central Bank Independence as an instrumental variable. Discuss whether or not such an index would be a valid instrument (discuss both relevance and exogeneity; note that instrumental validity is more of an economic rather than econometric concept

A researcher has a sample of 6 annual observations {94, 104, 102, 99, 111 and 107} for the CPI in country Z for the period 2015 to 2020, and wants to forecast CPI for the years 2021, 2022 and 2023. The researcher uses 3 different forecasting models: A, B and C. Model A is an AR(1) model with no drift and with an estimated autoregressive coefficient = 0.7. Model B is a MA(1) model with no constant and with an estimated MA coefficient = -0.4 (note the minus !). Model C is a random walk model with no drift. The error terms over the 2015-2020 period were estimated to have the values: {3, -1, 2, 4, -3, 1}. a. Compute the 2021, 2022 and 2023 forecasted values for the consumer price index based on the three models. Show the formulas and the details of your calculations, and explain all the related symbols. b. Suppose that the actual values of the CPI over the 2021, 2022 and 2023 were {108, 114, 105}. Calculate the Root mean square error of the three model forecasts over the 2021-2023…

An attempt was made to evaluate the inflation rate as a predictor of the spot rate in the German treasury bill market. For a sample of 79 quarterly observations, the estimated linear regressionŷ = 0.0027 + 0.7916xwas obtained, wherey = actual change in the spot ratex = change in the spot rate predicted by the inflation rateThe coefficient of determination was 0.097, and the estimated standard deviation of the estimator of the slope of the population regression line was 0.2759.a. Interpret the slope of the estimated regression line.b. Interpret the coefficient of determination.c. Test the null hypothesis that the slope of the population regression line is 0 against the alternative that the true slope is positive, and interpret your result.d. Test, against a two-sided alternative, the null hypothesis that the slope of the population regression line is 1, and interpret your result.

Candy is a Year 4 full-time undergraduate student majoring in marketing at a private university in Hong Kong and she is going to be graduated after the summer break. She has collected some data from the Student Careers and Affairs Office (SCAO) related to her job planning. According to the graduate employment surveys conducted for the last two years by the private university, the average salary earned by the graduates of her programme is constant at around $14,000. Actually, Candy is quite disappointed. In view of this, Candy is considering to participate in an one-year internship program launched by the SCAO after her graduation. In other words, she would enter the job market “formally” one year later if she joins the internship program. Finally, with the help of the SCAO, she could get an internship offer from a famous marketing company in Hong Kong. The monthly salary provided by the company is $12,000 while a good reference letter would be prepared for the interns completing the…
