The study performs unbiasedness and efficiency tests of interest rate expectations for thirty countries.
Unbiasedness test results show that expectations are biased in general, but individual country-specific results are mixed.
The efficiency test results show that forecasters do not incorporate all available information.
Emerging markets' interest rates are more predictable at the shorter horizon than the developed markets due mainly to higher inflation.
The results are robust and do not change at the different sub-periods.
