This research uses hierarchical linear modelling to test the KSTE in a developing-country context. By trying this theory on a different setting as is usually studied, we attempt to identify boundary conditions, expanding this theory's understanding. Results show the low effectiveness of this theory in a developing economy, suggesting that additional dimensions are needed to understand it completely. In reviewing the high-tech sector (the only sector in which we found evidence that the KSTE mechanisms apply), our data shows the importance of diversity for technological innovation and thus for firms born out of spillovers. Finally, we find that easiness to start a business interacts with human capital into forming high-tech new firms. Under a more bureaucratic system, high-knowledge human capital will have fewer incentives to switch from employment to self-employment and start a venture. By dealing with the specificities of developing economies when dealing with the KSTE, policymakers can avoid applying police recipes coming from findings related only to developed economies that cannot fit with the characteristics of these countries. In this context, this phenomenon is not particularly relevant for fostering new ventures, joining on the call of avoiding standardized strategies to build efficient entrepreneurial ecosystems.
