If 21 percent of the unemployed find jobs and 09 percent of the employed lose their jobs the natural rate of unemployment will be 31 percent 35 percent 41 percent 148 percent

The natural rate of unemployment can be calculated as:

Natural rate of unemployment = (1 - percentage of employed who lose their jobs) / (1 + percentage of unemployed who find jobs)

Substituting the given values, we get:

Natural rate of unemployment = (1 - 0.009) / (1 + 0.21) = 0.991 / 1.21 = 0.819

Converting this to a percentage, we get:

Natural rate of unemployment = 0.819 * 100% = 81.9%

Therefore, the answer is none of the options provided.
