Business owners are less optimistic about the health of the economy. 2. The government decreases welfare and veteran's benefits. 3. The Federal Reserve increases interest rates. 4. A rising price level decreases the value of money held for purchases. 5. The government lowers personal income taxes. 6. Consumers expect the job market to be much stronger in the next few months. 7.
