Designing Entrepreneurial Viability for Mid-Career Entry under Static Uncertainty

Abstract

Regional innovation ecosystems increasingly depend on experienced human capital, yet mid-career professionals remain systematically underrepresented in entrepreneurial entry. Existing entrepreneurship theories—from Knightian uncertainty to effectuation and lean experimentation—implicitly assume that entrepreneurial failure is reversible and that uncertainty can be reduced through action. While these assumptions hold for early-career founders, they become problematic for individuals embedded in dense life-course commitments. This paper argues that mid-career non-entry is not primarily psychological but structural, driven by static uncertainty—action-independent risks such as income discontinuity, constrained re-employment, and identity loss. We introduce the Life-Aligned Entrepreneurship Framework (LAEF), distinguishing between dynamic uncertainty (reducible through action) and static uncertainty (irreducible without institutional intervention). Under high commitment conditions, individuals optimize not expected value but survival viability under a ruin constraint. Building on this framework, we propose Static Uncertainty Design (SUD), a set of institutional mechanisms—administrative, contractual, and epistemic—that reduce irreversibility and enable entrepreneurial action. Using a qualitative case study of a regional entrepreneurship program in Japan, we show that mid-career individuals prioritize resolving static uncertainty before engaging in opportunity exploration. The paper contributes to entrepreneurship and innovation policy by reframing ecosystems as systems of downside-risk allocation and by offering actionable design principles for reducing downside risk and mobilizing experienced human capital.
