Once we identify the determinants of risk preferences, we investigate the role of risk preferences on firm output disparities utilizing the Penrose growth/output disparity/model. The study uses primary data based on random survey of the small-scale manufacturing firm owners in the zonal towns of the Tigray region. The multinomial logit and the multiple linear regression models are employed to identify the estimates of the factors of the risk preferences and the output disparity. The risk preference category of each sample firm owner was captured by employing the paper-format implicit association test (IAT) contextualized for this study. As a factor of risk preference, we find the soft budget constraint is a statistically significant variable only for the risk-averse and the risk-neutral owners. The factor of the risk preference (good perception of risk faced) is a statistically significant variable only for the risk-lover owners. Unlike the controversial negative relationship between firm owner's higher risk propensity and firm-level performances presented by some authors, this paper presents the normally expected positive relationship between the higher risk propensity and the output level.

Put it simple, using the economic complexity index of Africa (explanatory variable) as a proxy for the technological intensity in Africa and per capita GDP gap (explanatory variable) as a proxy for technology gap, the paper presents a significant and positive relationship between economic complexity index of Africa and the time derivative of the economic complexity index of Africa (the explained variable). This implies that “weak” effort African nations exerted so far in diversifying their outputs towards the less ubiquitous commodities and absence of “automatic catch up tendency” (unlike what is presupposed by the mainstream neo-classical growth models). The linear panel data regression is employed on sample of 23 African economies and OECD member economies for the...

Abstract Like other technology gap models, the application of “the Latin American Structuralism” ... more Abstract Like other technology gap models, the application of “the Latin American Structuralism” model in OECD & African countries reveals that the technology spillovers due to the technology gap is not as easy task as it was presumed by the mainstream growth theories. Using the per capita GDP gap between the OECD and sample African countries as a proxy for the technology gap, this paper indicates that the technology gap growth rate has been further soaring instead of revealing the normal falling tendency. The finding implies the absence of “automatic catch-up tendency” between the homogenous technology producing countries (OECD) and the heterogeneous technology extracting countries (Africa) and the “weak effort” African countries exerted so far to benefit from the technology gap in the form of spillovers from technology imitation. Among African relative sectoral growth contributions, the relative growth contributions of the agriculture and service sectors negatively affect the technology gap growth rate. However, they cause the equilibrium technology gap to further soar. It suggests the need for structural transformation in Africa. The two-steps difference GMM model is used on a panel of 34 African countries for ten years (2005-2014).
