“…Collecting primary data for this purpose offers the advantage that established survey instruments are available for both the effectuation and causation approaches and EO, whereas detailed secondary information on these issues is hard to get for a sufficiently large number of firms, especially for SMEs (Lyon, Lumpkin, & Dess, ; Perry, Chandler, & Markova, ).
