The Relationship

Item omission in mail surveys has received little attention other than as a variable measuring response quality in questionnaire design studies. Few researchers have attempted to examine item omission as a nonrandom process. The authors re-evaluate the nature of item nonresponse and analyze item omissions within topical domains. Two independent surveys and a replication study are reported. The tendency to omit survey items is tested for generalizability across domains and between similar studies. Sociodemographic correlates are investigated and a longitudinal analysis by item is performed. The results indicate that item omission is apparently a nonrandom process at an aggregate level, but the magnitude of the relationship is weak. When the data are disaggregated by topical domain, significant systematic relationships become less apparent.

Positive Effect

We examine the effect of combining internal and external R&D loci on innovation performance in family firms (FF) and nonfamily firms (non-FFs). Our longitudinal analysis of 27,438 firm-year observations of Spanish manufacturing firms from 1990 to 2016 shows that FFs can better exploit the benefits of simultaneously engaging in internal and external R&D activities, leading to a positive effect on innovation performance. Moreover, the relationship between combined internal and external R&D and innovation performance in FFs is contingent upon firm economic performance. By pointing to the importance of taking into account the combination of internal and external R&D loci to foster innovation in FFs, we challenge current family business innovation research.

Don’t “Waste” Your Time! The Effects of Time Series Errors in Management Research: The Case of Ownership Concentration and Research and Development Spending

The Relationship

The potential effects of “time series errors” in longitudinal analysis are examined empirically. Using a common hypothesis (the relationship between ownership concentration and research and development (R&D) spending) and a panel of 183 Fortune 500 firms (I 985-l 988) several time series errors are calculated. These analyses are then contrasted with the results of a procedure protected from time series errors. Comparisons show that (I) results may depend upon how researchers define and measure longitudinal effects; (2) time series errors can have significant effects on empirical findings; and (3) the linkage between ownership concentration and R&D may not be as clear-cut as previous studies have suggested. Recommendations for how researchers should account, save, and tell their time are offered.
