Summary
In spite of the rich body of evidence on the effects of HPWS, there are at least two relatively unexplored yet potentially important questions: (i) The conditions under which the HPWS is best introduced and best sustained; and (ii) in what way the HPWS will need to evolve when external environments change. Our findings fill this important gap in the literature by providing novel evidence and insight on the causal link from product market competition to employee involvement.
