Document Summary

The consensus is that the unemployment rate is constant at 4. 9% The unemployment rate equals the number of unemployed persons divided by the total number of persons in the labor force, which comes from a survey of 60000 households (called the household survey). Workers are counted only once no matter how many jobs they have or whether they are only working part time. In order to be counted as unemployed one must be actively looking for work. The unemployment rate is expected to hold at 4. 9% while average earnings are expected to rise a steady 0. 2%. A 0. 3 % rise for earnings, stronger than expected payroll growth or a tick lower in the unemployment rate could raise talk of an april. All three of these are very inflationary in nature and would mean the. A country will export a good if the world price of a good is higher than domestic price without trade.
