To explore this, we need an economic model of the labor market. In such a model, the Beveridge curve is derived from a mathematical framework that determines the rate at which workers are hired given job vacancies and unemployment rates, and how efficiently workers are matched with available jobs. Thus, the hiring rate depends on the number of unemployed workers, the number of available job openings, and how much effort businesses put into filling vacancies, for example, by advertising. For a given number of job openings, if more people are unemployed and searching for jobs, then typically more hiring takes place because it is easier for businesses to find suitable candidates to fill vacancies. Similarly, for a given number of unemployed workers, an increase in job openings makes it easier to find jobs, also boosting the hiring rate.
