An important feature of DSGE models is that they explicitly incorporate the fact that people’s expectations about the future affect their behavior today. We can illustrate this feature in our simplified framework by considering the arrival of some “good news.” Imagine, for example, that people in the economy learn of a new technological discovery that will make the economy more productive starting 5 years in the future. Consider the effect of this shock today using the labor market diagram of a standard DSGE model (with no sticky prices or wages).
(a) What happens to the labor demand schedule?
(b) What happens to the labor supply schedule?
(c) What is the effect on the real wage and employment in the short run?
(d) How would your answer change if there are sticky prices?
