Consider a simple model of a time series ytas a function of its past (using lagged values): Yt = Bo + B1Yt-1 + €7 (1) Assume that yt is what we refer to as 'stationary - its distribution does not change over time, i.e. E[yt] = for all t. i iii Interpret the model - what does B, capture? Show that E[yt] is equal to Q = Bo/(1-B1) Now consider the model including an additional variable xt:...

Exercise 1. Production function model Consider an economy "I" with a representative household that consists of 1000 workers and owns $100 million of capital (L 1000, K -100). There is a representative firm with a Cobb- Douglas production function that rents capital and hires labor to produce. Assume that the TFP parameter equals one (A-1), we have Y K1/3L2/3. Markets are competitive. 1. Define an equilibrium in this economy. Follow class notes. 2. Solve for the equilibrium. You should get...

In this problem, we will model the likelihood of a particular client of a financial firm defaulting on his or her loans based on previous transactions. There are only two outcomes, "Yes" or "No", depending on whether the client eventually defaults or not. It is believed that the client's current balance is a good predictor for this outcome, so that the more money is spent without paying, the more likely it is for that person to default. For each x,...
