The concept of emotional capability is one of the competencies that a firm has which is vital for the daily life of the organization. However, the effect of emotional capability, involving the dynamics of encouragement, displaying freedom, playfulness, experiencing, reconciliation, and identification constructs on the firm innovativeness (i.e., product and process) is interestingly missing in the technology and innovation management (TIM) literature. In this study, by investigating 163 Turkish firms, the dynamics of encouragement and experiencing were found to have a positive association with both firm product and process innovativeness; and the dynamics of displaying freedom have a positive relationship with firm process innovativeness. We also demonstrate that the impact of emotional capability constructs on firm innovativeness is contingent upon environmental uncertainty. Specifically, we find that the influence of the dynamics of encouragement on firm product innovation increases with increased rate of environmental uncertainty. Interestingly, the relationship between the dynamics of experiencing and product innovation across low, medium, and high levels of environmental uncertainty is an n-shaped. And, the relationship between the dynamics of displaying freedom and product innovation across low, medium, and high levels of environmental uncertainty is a U-shaped. In addition, we show that a firm's emotional capability influences its financial and market performance via firm innovativeness. We discuss the theoretical and managerial implications of the study's findings. (C) 2009 Elsevier B.V. All rights reserved.
