Each entry-level software programmer in Palo Alto, California, has either high or low ability. All potential employers value a high-ability worker at $12,000 per month and a low-ability worker at $6,000. The supply of high-ability workers is QHS=0.1(W7,000) and the supply of low-ability workers is QLS=0.1(W2,000) where W is the monthly wage. If workers' abilities are observable to employers, what are the equilibrium wages? How many workers of each type will employers hire? If workers' abilities are not observed by employers, what is the equilibrium wage? How many workers of each type will employers hire? Compare the results for when abilities are not observable to when abilities are observable. Show how you arrived at your answers
