3. Consider the following regression equation, where Cigs is daily spending on cigarettes in poundssterling (£), Y earsEduc is years of education, and F emale equals one if an individual is femaleand zero otherwise (standard errors in parentheses):Cigs [ = 4(1.6)− 0.08(0.032)Y earsEduc − 0.5(0.2)F emale,(a) Interpret the coefficients on Y earsEduc and F emale. (b) What does the model predict the average daily spending on cigarettes would be for womenwith 12 years of education? (c) Form the 95% confidence interval for the coefficient on F emale. (d) Economists are often interested in estimating production functions of the Cobb-Douglas form(Yiis the ith firm’s output, Liits spending on labour, and Kiits spending on capital):Yi = ALαi Kβi,How might someone estimate α and β from this equation using linear regression?

- Case Study: The Impact of Ebola on Tax Revenue in the DRC Background: The Democratic Republic of the Congo has experienced mulitiple outbreaks, with the 2018-2020 outbreak being one of the most severe. The outbreak had profound effects on public health, the economy and government operations. The DRC's economy already fragile due to policital instability and conflict, faced additional stain as the Ebola virus spread across several provinces. Economic disruption: The Ebola outbreak led to significant disruptions in the affected regions. Businesses were forced to close or reduce operations due to quarantine measures and the fear of contagion. this resulted in a sharp decline in economic activities, particularly in sectors such as agriculute, mining and trade. reduced consumer spending and interruptions in supply chains further exacerbated the economic downturn.
