Competition and productivity Michael Polder, Erik Veldhuizen, Dirk van den Bergen and Eugène van der Pijll International Statistical Conference Investment in the Future 2 Prague, Czech Republic 14-15 September, 2009 Micro and macro indicators of competition: comparison and relation with productivity change
Introduction Application of Dutch growth accounts Combining micro and macro data Competition and productivity
Multi-factor productivity KLEMS-Y model (consolidated) Index MFP = Exogenous interest rate Labour income self-employed
Competition indicators Herfindahl index C4 indicator Price cost margin Labour income ratio Profit elasticity Import quote Export quote Concentration indicators Profitability indicators International competition
Data and methodology Dutch manufacturing (12 industries) Final year data covering period 1996-2005 Macro and aggregated micro data Correlations between indicators Simple linear regressions (OLS) Contemporaneous and lagged
Correlations between indicators Similarity of micro and macro indicators
Correlations between indicators Similarity of micro and macro indicators Different dimensions of competition Differences between industries
