The current U.S. unemployment insurance program tends to (1) increase the incentive to switch occupations. (2) raise the unemployment rate. (3) reduce the time workers stay unemployed. (4) make it more costly for unemployed workers to turn down available jobs.

The current U.S. unemployment insurance (UI) program exhibits several tendencies based on economic analysis: 1. **Increase the Incentive to Switch Occupations**: **True.** UI provides financial support to unemployed workers, allowing them more flexibility and time to seek jobs that better match their skills and interests. This can encourage individuals to switch occupations or pursue further training and education. 2. **Raise the Unemployment Rate**: **True.** Since UI benefits are typically available to individuals who are actively seeking work, some may choose to remain registered as unemployed longer than they would without benefits. This can contribute to a higher measured unemployment rate. 3. **Reduce the Time Workers Stay Unemployed**: **False.** On the contrary, UI can sometimes increase the duration of unemployment by reducing the immediate financial pressure to accept the first available job offer. This allows workers more time to find a suitable position but can extend the period they remain unemployed. 4. **Make It More Costly for Unemployed Workers to Turn Down Available Jobs**: **False.** UI generally reduces the financial strain on unemployed individuals, making it less costly (not more) to turn down jobs that are unsuitable. Workers are less pressured to accept any job quickly, enabling them to seek better matches for their skills and preferences. **Summary:** Statements **(1)** and **(2)** accurately describe tendencies of the current U.S. unemployment insurance program. **Answer:** Both statements 1 and 2 are tendencies of the current U.S. unemployment insurance program.
