The employee (A) and the employer (B) have to make decisions. A has to choose whether to pursue training that costs $1,200 or not. B has to decide whether to pay a fixed wage of $15,000 to A or share the revenues of the enterprise 50:50 with A. The output is affected by both training and revenue sharing. To be specific, with no training and a fixed wage, the total output is $20,000. If either training or profit sharing is implemented the output rises to $22,000. If both training and revenue sharing are implemented, the output is $25, 000.
