摘要: This paper estimates trend growth rates for a sample of industrial countries by applying Okun's law in first differences. Despite the simplicity approach and restrictive assumptions, method typically yields reasonable results when shifts Okun coefficients changes structural unemployment are allowed for. Particular caution is required using estimating output gaps.
