    Internal innovations, foreign technology and productivity in Sub-Saharan Africa’s manufacturing
    (Research square, 2022) Bbaale, Edward; Kilimani, Nicholas; Okumu, Ibrahim Mike; Tumwebaze, Henry
    Internal firm innovations and external knowledge/technology transfer are key for spurring the growth of firms and economies. We investigate whether firms that engage in such innovations are more likely to be productive than others as well determine if external knowledge transfers may have an effect on labor productivity mediated by the existence of internal absorptive capacity (generated by human capital and R&D). Using the World Bank Enterprise Survey of 26 African countries and employing both OLS and 2SLS, we find that firms that engage in innovations experience more growth. Most fundamentally, importation of inputs alone in the absence of other innovations does not maximize firm productivity. Finally, firms with a higher absorptive capacity in addition to the other innovations enjoy higher efficiency gains from their imported inputs irrespective firm ownership and size. Government should pursue policies that enhance internal absorptive capacity so as to enable firms tap the global opportunities.

    Labour Productivity among Small- and Medium-scale Enterprises in Uganda: the Role of Innovation
    (Journal of Innovation and Entrepreneurship, 2018) Okumu, Ibrahim Mike; Buyinza, Faisal
    Using the 2013 World Bank Enterprise Survey data for Uganda, this paper employs the quintile estimation technique to explain the relationship between labour productivity and innovation among SMEs. Innovation involves the introduction of a new or significantly improved production process, product, marketing technique or organisational structure. Our results indicate that the relationship between labour productivity and a firm engaging in any form of innovation is neutral. However, there is evidence of complementarity among product, process, marketing and organisational innovation. Specifically, there is a positive association between labour productivity and innovation when a firm engages in all the four innovation types. Even then, the complementarity effect turns out weakly positive with incidences of negative relationship when using any combination of innovations that are less than the four types of innovations. Our results suggest that efforts to incentivise innovation should be inclusive enough to induce all the four forms of innovation.

    Performance of Small and Medium-sized Enterprises in Uganda: the Role of Innovation
    (AERC., 2020) Okumu, Ibrahim Mike; Buyinza, Faisal
    Using the 2013 World Bank Enterprise Survey data for Uganda, this paper employs the quintile estimation technique to explain the relationship between innovation and firm performance in small and medium-sized enterprises (SMEs). Innovation involves the introduction of a new or significantly improved production process, product, marketing technique or organizational structure. Our results indicate that individual processing, product, marketing and organizational innovations have no impact on labour productivity as proxied by sales per worker. However, the results indicate the presence of complementarity between the four types of innovation. Specifically, the effect of innovation on sales per worker is positive when an SME engages in all four types of innovation. Even then the complementarity is weakly positive with incidences of a negative relationship when using any combination of innovations that are less than the four types of innovation. Policy-wise the results suggest that efforts to incentivize innovation should be inclusive enough to encourage all four forms of innovation.

    Reaching the last 10 percent out of school children: the role of AIDS
    (African Journals Online (AJOL), 2016) Okumu, Ibrahim Mike; Mugisha, Frederick
    This paper investigates the role of AIDS on children being out of school. Put differently, whether it is because of AIDS that children are out of school. The main data source was the Northern Uganda Survey of 2004 conducted by Uganda Bureau of Statistics (UBOS) between July and December 2004. The survey was meant to provide indicators to guide the monitoring and evaluation function of the NUSAF project period in 18 districts of Northern Uganda. We defined and identified ‘aids affected households’, used descriptive analysis as well as a multinomial specification. We further explored the role of poverty using changes in household asset value between 1992 and 2004. There is no conclusive evidence that children are out of school due to AIDS. AIDS has a marginal effect on children failing to continue in school but this is not statistically significant. However there is strong evidence that children are out of school because of a decline in household asset value. To reach children who have never attended school, rather than focusing on ‘AIDS affected households’, a much greater impact is expected from preventing major decline in ‘household asset value’.

    Realized Access to Antenatal Care Utilization in Uganda: Household Welfare and Governance Implications
    (African Journals Online (AJOL), 2016) Okumu, Ibrahim Mike; Bbaale, Edward
    The rationale of this study is to explain the link between household welfare, the region in which an infant is situated, literacy level of a mother and malaria prevalence among infants in Uganda with a more recent nationally representative data set that is the 2006 Uganda Demographic and Health Survey in lieu of the findings by other researchers on this particular subject. This was done with the aid of logit model estimation. The findings indicate that the region where an infant situated is fundamental in explaining malaria prevalence among infants. Alongside region is the location of a child whether he or she is in the rural or urban setting, the findings indicate that malaria prevalence lower among urban infants as compared to their rural counterparts. In conclusion, it was observed that malaria prevalence is not a case of household socioeconomic conditions but rather it's a communal disease as exemplified by the significance of region and urban-rural location of an infant.

    Socio-Economic Status and Malaria Prevalence among Infants: the Case of Uganda.

    The Changing Employment Landscape in Uganda
    (African Journals Online (AJOL), 2023) Ssebulime, Kurayish; Okumu, Ibrahim Mike; Bbaale, Edward
    The employment landscape in Uganda and across the globe has continued to change at an unprecedented rate. This has mostly manifested in employment shifts within and between sectors. A large share of Labour force has shifted towards the service sub-sectors with a corresponding shift away from agriculture and other goods-producing sectors. Employment intensities of growth were estimated in this study to ascertain whether employment shifts have occurred in Uganda and also establish the causes of the variations using multivariate regression and autoregressive distributed lag modelling. The study established that there is no evidence of sectoral employment shifts in Uganda. The agriculture sector has the least employment intensity of growth followed by the industry and the service sectors. Trade and repairs, arts, entertainment & recreation, cash crop, food crop, construction, and manufacturing have the highest employment intensity of growth.
