For the general multiple regression model y =B₁ + B₂x₂ +B₂x₂ + ... + B x x x + e the following two assumptions are called and E (e₁|X) = 0 and var (e;|X) = 0²

The Great Recession of 2007-2009 hit young people particularly hard, with long-lasting effects. The U.S. unemployment rate for 20- to 24-year-olds went from 8.5% in 2007 to 16% in 2009, stayed above 13% through 2012, but fell to 7% by the first half of 2018. As a result, more adult children moved back to live with their parents or asked for financial help than in previous years. The share of 25- to 34-year-olds living in multigenerational households rose from 11% in 1980 to 15% in 2016. A recent survey finds that 41% of parents provide financial support to their 23- to 28-year-old offspring. Indeed, parents give 10% of their income on average to their adult children. Mimi wants to support her son Jeff if he looks for work but not otherwise. Jeff (unlike most young people) wants to try to find a job only if his mother will not support his life of indolence. Mimi and Jeff's payoff matrix is illustrated in the figure to the right. If Jeff and Mimi choose actions simultaneously, what are…

Compute the R² using the following information. What does this number mean? Wage = 4.43 +0.61Edu + e n = 1089, SST = 37211.6, SSE 37211.6, SSE 19848.2 R² = = = 0.4666. 46.66% of the variation in wage can be explained by education. R² = 0.5334. 53.34% of the variation in wage can be explained by education. R² = 0.61.61% of the variation in wage can be - explained by education. R² = 0.3043. 30.43% of the variation in wage can be explained by education.

DNFP7 (a) The President of ALS Society of America asks you to determine whether the level of ALS research in the U.S. is close to where it should be. You decide to estimate the demand and supply curves for ALS research, which you are thinking of as a pure public good. You find that there are two types of people in the U.S., each with a very different demand for autism research: Mother Teresas: P=$50-2Q Scrooges: P=$10-Q You also estimate that the marginal cost of producing each ALS study is $20. a. Sketch the Demand Curves for Mother Teresas and for Scrooges? • Label the x and y Intercepts. Mother Teresas: P-$50 when Q-0 Q-25 when P-0 Scrooges: P-$10 when Q-0 Q-10 when P-0
