Suppose that X represents the number of years a person goes to school, and Y represents the income they earn after finishing those years of school. Year of schooling is widely believed to be a major determinant of income. Explain whether this correlation is likely to be casual or not.
Exercise 4. Mary is investigating the determinants of house prices in 90 cities. She gathers information on house value in log (Inhseval), the size of the house (sizehse), and income per capita in log (Inincome). She also gathers information on the property tax rate, specifically if cities have the low property tax rate (less than 2.5%), or the high property tax rate (2.5% or more). She runs the following regression: Ln(hseval;)= a + B₁(sizehse;) + B2 (income)+ &; And then she separates the regression by low and high property tax rate. The results of her regression analysis are given in the tables below. Regression results: Dependent variable is Ln(hseval;) Source Model Residual Total 1nhseval. sizehse Inincome cons Source Model Residual -> lowtax High tax rate Total 1nhseval sizehse inincome _cons Source Model Residual Total SS 1nhseval 1.56064571 2.98039214 4.54103785 sizehse inincome _cons SS -> lowtax Low tax rate Coef.

Suppose that X represents the number of years a person goes to school, and Y represents the income they earn after finishing those years of school. Years of schooling is widely believed to be a major determinant of income. The correlation between education and earnings is positive. Explain whether this correlation is likely to be causal or not.
