Productivity measures are key indicators of economic performance and a key source of economic growth and competitiveness. The Organisation for Economic Co-operation and Development (OECD)’s Compendium of Productivity Indicators, published annually, presents a broad overview of productivity levels and growth in member nations, highlighting key measurement issues. It analyses the role of “productivity as the main driver of economic growth and convergence” and the “contributions of labour, capital and MFP in driving economic growth”. According to the definition above “MFP is often interpreted as the contribution to economic growth made by factors such as technical and organisational innovation” (OECD 2008,11). Measures of productivity include Gross Domestic Product (GDP)(OECD 2008,11) and multifactor productivity.
