What are pure specific factors model and mixed pecific factors model? How does the two differ?
Consider a simple model of marriage and wage Yit = BXit + Sit + Vit where Y is the wage, X is a dummy variable indicating the marital status, S represents "sociability," and V contains other unobserved causal factors. Assume that Vit is independent of Xis for all i, t, s. We observe a panel data of (Yit, Xit). Which of the following condition(s) are sufficient for us to obtain a consistent estimate of B? Sit is independent of Xit Sit does not vary with time t Vit does not vary with time t Sit is independent of Vit

The lag effect suggests that studying that is spaced out over a greater amount of time provides more of an advantage than spacing over shorter periods of time. Provide a brief description (1-2 sentences) of the lag effect.

In 2006, Evo Morales assumed the presidency in Bolivia, a South American country in which official commerce is done in Spanish. Morales was the first Bolivian president of indigenous decent. As president, he quickly instituted reforms that were designed to reduce discrimination against indigenous populations with the aim of eventually reducing inequality. Suppose discrimination before Morales took two forms: discrimination in education by not providing state funds to educate all children (and particularly not educating indigenous children in Spanish) and discrimination in the job market by firms not willing to hire indigenous workers.a. In terms of education, which policy do you think would be more successful at combating discrimination and inequality: (1) providing state funds to educate all people exclusively in their native languages or (2) providing state funds for a public education system that requires all people to learn Spanish, as well as a second, indigenous language? Why?b.…
Cristina is excited with these averages and tells her public relations team to prepare a glossy brochure to showcase this $250 increase in household income. which of the following must be true to confidently conclude that this $250 difference in average income was caused by access to a UThere The herders who bought UThere phones would have had higher income than the herders who did not even if they had not purchased the UThere phone. The herders who bought UThere phones would have had the same income as the herders who did not even if they had not purchased the UThere phone. We don’t need to worry about Selection Bias since Nepal and Tibet are small countries with more or less similar people. The equation for Selection Bias does not provide enough information since we do not know the counterfactuals.
Suppose you are interested in studying the effect of time spent in an SAT preparation course on actual SAT score. You propose the following regression of SAT score on hours spent in preparation for SAT and family income: Y = Bo + BiX + B2X2 + u Where Y = score on SAT X₁ = time spent in studying in an SAT preparation course X₂ = income of the student's family u = error term An important assumption in the regression model with two independent variables is that E(u|x₁,x₂)=0. Assume for simplicity that the only other relevant factor (contained in the error term) that affects Y is natural ability. That is, natural ability and u are essentially equivalent in your regression. In the context of your proposed regression, this assumption assumes which of the following?
assume there are two types of workers, low- and high-ability, andlet 0 = 0.25 be the proportion of high-ability workers in the population. Assume their marginalproductivity and, therefore, their wages are wh = $20 and wl = $16, and that both types canuse college education to signal high ability. The cost of college education for low-ability workersis cl = $5 whereas the cost for high-ability workers is ch = $2. Consider the wage for both types of workers and the high-ability workers’ college cost, ch. For which values of 0 (the proportion of high-ability workers in the population) do the high-ability workers prefer the separating equilibrium over the pooling equilibrium? (a) Any 0 > 1/2(b) Any 0 < 1/2 (c) Any 0 < 3/4(d) Only when 0 = 1
