The present research work analyzes the contribution of the restriction of technical capacities to the level of human development registered in the local governments of Ayacucho during the period 2010-2012. This paper is testing to evaluate if during 2010-2012 period, the reduction of human development levels of the local governments of the department of Ayacucho is due to the restriction of technical capacities that limit the execution of public investment at the local level. In particular, the results obtained support the research hypothesis that during the reference period, the expenditure of the local governments of the department of Ayacucho is mainly limited by two factors: first, the restriction of technical capacities in municipal policy and management; and second, the strategic planning. These two factors in turn, reduce the execution of public investment by 9.32% and 6.12%, respectively. Likewise, this capacity restriction contributes to a reduction in the execution of public investment by 8.35%. Additionally, it is found that, although the impact of public investment on human development at the local level is positive, in terms of magnitude, it is relatively minor, as shown in the empirical work carried out by Correa & Morocho (2015). Finally, it is found that during the period 2010-2012, the technical capacity constraints in municipal policy and management, plus lack of appropriate strategic planning, reduced the Human Development Index (HDI) of the local governments of Ayacucho by 0.10%, 0.06% and 0.08%, respectively.
