The Role of Sunk Cost and Slack Resources in Innovation: A Conceptual Reading in an Entrepreneurial Perspective

Abstract This paper proposes a conceptual reading of the interplay between sunk costs and slack resources in innovation, adopting an entrepreneurial perspective. Antecedent literature mostly depicts the relationship between slack and innovation as an inverse u-shaped curve. However, this approach is way too unrealistic and it does not take in account both the different impact of heterogeneous types of slack and of sunk costs. We argue that not all slacks positively contribute to innovation and, hence, the u-shaped relationship is merely verified in case of highly flexible slack resources. In addition, the presence of sunk costs is a friction factor, which makes the first part of the curve less steep. Therefore, entrepreneurs are solicited to innovation by the presence of some easy recoverable slack types, as financial or knowledge ones. On the converse, a consistent level of sunk cost may discourage their innovative activity. In this setting, absorbed slack resources increase the level of sunk costs.

How does firm diversification impact innovation

ABSTRACT This study sheds light on the relationship between business diversification and innovation. A diversification strategy is both a driver of sunk costs and strategic slack. Strategic slack is a valuable reserve of knowledge, usable to foster innovation. Using linear models, we explore the interplay between research and development (R&D) and organisational slack in large and diversified companies listed on the Euronext 100 Index. We consider the diversification pattern over time, and its interactions with the following three categories: sunk costs, slack resources, and R&D. The results show an antithetic effect of diversification and slack on R&D expenditures. In contrast to unabsorbed and potential slack, diversification and sunk costs hinder innovation. However, diversification is a huge source of strategic slack and, thus, has a positive effect on innovation, indirectly.

A bottom up approach to unlevered risk in a financial and managerial perspective

In financial theory, there are several models that study the risk-return relationship. However, the capital asset pricing model (CAPM) still remains the most popular among financial analysts and firms (Bernardo et al., 2007; Graham and Harvey, 2001; Jagannathan and Meier, 2002).

Open collaborative innovation and digital platforms

Abstract This study uses contract theory to analyse the relationship between open collaborative innovation strategies and digital platforms. We argue that a collaborative mechanism and governance of the platform affect how operations are run and impact firm ambidexterity. We also explain how the twofold revealing strategy, both selective and free occurs via the platform and how governance positively impacts the coordination mechanism. A case study analysis on TIM OPEN draws a ground-breaking framework for future investigations. The analysis suggests that the combination of digital platform and collaborative innovation can facilitate the creative process and be a driver of operational synergies. Results confirm that the adoption of digital platforms for collaborative innovations reduces transaction costs.
