5) Edward Lazear analyzed data provided by the Safelite Group, the nation’s largest installer of
auto glass, after the company changed the way it paid its glass installers beginning in the mid-
1990s. Instead of paying workers hourly wages, Safelite began to pay workers on the basis of
how many windows they installed. Which of the following describes what Lazear concluded
from his analysis of Safelite’s data?
A) Although workers installed more windows under the new system, Lazear found that there was
also an increase in the number of workmanship-related defects. Lazear attributed this to workers
taking short-cuts in order to earn higher wages. As a result, productivity did not improve and
Safelite went back to paying hourly wages.
B) Lazear found that worker productivity increased with the new system; about half of the
increase in productivity was due to workers who continued with the company and half was due
to new workers being more productive than those who left the company.
C) Although worker productivity improved, the increase in hourly wages resulted in a significant
decline in Safelite’s profits.
D) Because of a principal-agent problem, worker productivity was not affected by the new
compensation system. However, Lazear attributed this to management problems that had nothing
to do with Safelite’s compensation system.
6) Which of the following is not a reason for firms to choose a salary system rather than a
commission system to compensate their employees?
A) Research has shown that most companies will find that a salary system will be more
profitable than a commission system.
B) It is often difficult to attribute output to particular workers.
C) If workers are paid on the basis of the number of units of output they produce, they may
become less concerned about quality.
D) Commission compensation systems are riskier for employees than a salary system, and many
workers dislike risk.
