Human Resources: One of the key human resource challenges facing the company is turnover. Employee turnover is costly because it takes time to fill a vacancy, recruiting costs are high, and once the vacancy is filled, it requires considerable time before the new employee is fully trained. The company is considering raising wages to reduce turnover, but this is costly. They would like you to analyze the effect of wage on turnover. The company pays higher wages when more of its workforce has a college degree, when the unemployment rate is low, and when the labor market is strong (which generally means that turnover is high). They have experimented with giving some regions a "budget boost" to raise wages. They believe the budget boost has no direct effect on turnover
