Prior research has revealed a negative association between family influence and R&D spending. The dominant explanation for this association centers on the role of socioemotional considerations in decision-making. These socioemotional decision considerations are argued to play a more prominent role among family firms and to lower their R&D spending intensity. However, to date, this negative explanatory mechanism has not been empirically verified. Moreover, a deeper analysis of the literature suggests that some family-induced socioemotional considerations may actually stimulate R&D investments. In this study, four socioemotional decision considerations are delineated-namely, concern for current control, for extended preservation, for organizational reputation, and for organizational values and traditions-of which the first two are anchored in a family's nurturer role identity and the latter two in a family's organizational identification. It is hypothesized that those socioemotional considerations derived from a family's nurturer role identity constrain R&D spending, while those derived from the family's organizational identification boost R&D spending. The empirical study concentrates on the setting of privately held manufacturing SMEs, and using survey data on 365 such companies in the Netherlands, a structural equation model is estimated. The analyses reveal several interesting results: (1) the overall association between family firm status and R&D spending indeed turns out to be negative, and this negative effect is fully explained by family firms' preoccupation with extended preservation; (2) concerns for organizational reputation and for organizational values and traditions partly compensate the negative effect of the extended preservation mechanism. Key academic and practical implications of these findings are discussed.
