Decoding the Financial Zeitgeist: A Scientific Exploration of the Calculus of Capital for Cost-Efficient and Sustainable Growth in Investments and Operations

Objective: to examine financial dynamics within the financial zeitgeist, focusing on capital calculation and cost-effectiveness for sustainable investment and operational growth. Methods: data from 200 stakeholders in Kosovar companies (2022–2023) Were analyzed using SPSS and AMOS, with exploratory and confirmatory factor analysis, reliability analysis, and structural equation modeling (SEM) to assess direct and indirect effects among cost and operational efficiency (CaOE), investment dynamics and industrial impact (IDaII), and operational capacity and development (OCaD). Results: CaOE had a positive effect on both IDaII and OCaD, with IDaII also positively impacting OCaD. CaOE’s indirect effect on OCaD via IDaII was significant. Key factors included maintenance costs for CaOE, competitive advantage for IDaII, and technological advancement for OCaD. Conclusions: the model showed excellent fit, confirming the proposed relationships. Firms should integrate investment strategies, operational efficiencies, and development capabilities for sustainable growth.
