    The flexible accelerator model of investment: An application to Ugandan tea-processing firms
    (African journal of agricultural and resource economics, 2015) Twine, Edgar E.; Kiiza, Barnabas; Bashaasha, Bernard
    The study uses the flexible accelerator model to examine determinants of the level and growth of investment in machinery and equipment for a sample of tea-processing firms in Uganda. Using a dynamic panel data model, we find that, in the long run, the level of investment in machinery and equipment is positively influenced by the accelerator, firm-level liquidity, and a favourable investment climate in the country. Depreciation of the exchange rate negatively affects investment. We conclude that firm-level strategies that increase output and profitability, and a favourable investment policy climate, are imperative to the growth of the tea industry.

    Pricing Rice Quality Attributes and Returns to Quality Upgrading in Sub-Saharan Africa
    (Journal of Agricultural and Applied Economics, 2022) Twine, Edgar E.; Ndindeng, Sali Atanga; Mujawamariya, Gaudiose; Futakuchi, Koichi
    The study applies parametric and nonparametric estimation methods to determine hedonic prices of rice quality attributes, and a partial equilibrium model to determine the payoff to investing in quality improvement in five countries in Sub-Saharan Africa. Results indicate that consumers are willing to pay price premiums for head rice, slender grains, peak viscosity, parboiled rice, and rice sold in urban markets. However, they strongly discount amylose content, rice with impurities and imported rice. Investing in quality improvement through amylose content reduction leads to net welfare gains with a benefit-cost ratio of 47.86 and internal rate of return of 90%.
