This paper presents new time series estimates of GDP, capital stock and education-adjusted employment, and uses a growth accounting approach to analyze GDP growth during 1880-2008. The growth of capital stock, employment and educational attainment explained almost all of GDP growth. During key growth periods 1900-29 and 1975-97, Total Factor Productivity (TFP) growth was on balance negative. TFP growth was substantial during some sub-periods, particularly 1933-41, 1951-61, 1967-74 and 2000-08. Each followed a major economic downturn that slowed capital stock growth and required a more efficient use of productive resources, supported by changes in economic policy that enhanced productivity and efficiency.
