Title: A note on testing for complementarity and substitutability in the case of 
	 multiple practices 
Abstract: Recent empirical studies of firm-level performance have tested 
	 complementarity in the case of multiple practices. These papers have 
	 drawn conclusions using potentially biased estimates of pair-wise 
	 interaction effects. We develop a consistent and simple testing 
	 framework and test it against alternatives.
