Final answer:
Job vacancies are indeed filled quickly through recruitment agencies, which function as a clearinghouse and can lead to permanent positions, thus reducing the natural rate of unemployment. The development of the internet has further enhanced the efficiency of job search and application processes.
Step-by-step explanation:
It is true that job vacancies can be filled quickly using the help of recruitment agencies. Since the 1980s, there has been significant growth in the temporary worker industry, indicating a trend where a higher percentage of workers found jobs through temp agencies. These agencies not only provide immediate work for individuals seeking permanent employment but also act as a clearinghouse to connect workers with potential employers, often resulting in formal employment that may not have been attained otherwise.
Meanwhile, the advent of the internet and social networking sites like LinkedIn has revolutionized the job search process, making it easier and more efficient for job seekers to explore opportunities and for employers to find suitable candidates for their positions. The convenience of an online job search compared to traditional methods has also contributed to the reduction in frictional unemployment.
