While economic booms are generally positive, they also have a dark side.
This is because _____.
A. if the economy is close to full employment and full capacity utilization before the beginning of the boom, the economy might eventually experience a leftward shift in labor demand, causing a recession rather than a gentle fall to pre-boom levels.
B. politicians often like to "fan the flames" of booms to increase their popularity, especially during an election year.
C. firms may decide to increase worker productivity at the expense of hiring new workers, leading to an increase in firms' profits but not an increase in employment.
