A model of the labor market. In this question, your task is to understand how the labor market responds to an economic downturn using the model we developed in Lecture 8. Suppose the matching function is given by u\" (m + my)\": ' where A governs the efciency of the matching process, a is the unemployment rate and v is the vacancy rate. Here, 7,! is a parameter that governs the elasticity of the matching function. Assume each period in the model corresponds to a month. Parameter values are provided in Table l. M(u,v) =A Separate rate: 3 002 Matching eiciency: A 1.0 Matching elasticity: n 0.5 Vacancy posting cost: c 0.5 Match value: J 4 Table 1: Parameter values for labor market model (1) Using the parameter values in Table 1, calculate the steadystate values of labor market tightness 9, unemployment rate a and vacancy rate a. (2 points) (2) Suppose the economy is initially in steady state (3 = 0). At t = 1, a recession causes the value of lled jobs J to decrease to J = 2 for 15 months. Starting from the steady state, use the other parameter values in Table 1 and a spreadsheet /script to calculate and plot the time paths of market tightness, unemployment rate and vacancy rate for 15 months (t = 0,1,..., 15) after the economy was hit by the recession. Describe how market tightness, unemployment rate and vacancy rate respond to the decrease in J. Has the economy settled to a new equilibrium by the end of 15 months? Explain your ndings. (2 points)
