SUMMARY:PhD Public Defense by Mr. Jordan Paul Semwanga
DESCRIPTION:INVITATION:  The Dean of the School of Economics\, College of Business and Management Sciences (CoBAMS)\, Makerere University invites you to a Viva Voce examination for Mr. Jordan Paul Semwanga on Wednesday\, 23rd of April 2025\, at 2PM in the College Conference Hall\, Makerere University. \nDate:  Tuesday 23rd  April 2025. \nTime: 2:00 pm \nVenue: The Conference Room\, Level 2\, Block B\, College of Business and Management Sciences (CoBAMS)\, Makerere University. \nTitle: “Crop production and welfare effects of using sludge manure among rural households in selected districts of central Uganda.” \nABSTRACT \nThe quality of arable soils has continuously deteriorated in Uganda. This has resulted into reduced crop production and constrained household welfare especially among the poor and agro-based households. Many farm households have tried to adapt to the losses in soil fertility through the use of inorganic and organic supplements. Although\, a vast body of literature exists that demonstrates the positive impact of either inorganic or organic supplements but one can argue that little evidence exists about the impact of sludge manure on household crop production\, household welfare\, and the economic viability of its use. Thus\, this dissertation examines the impact of sludge manure on rural farm households’ economic outcomes. To elaborate\, the dissertation address three key specific objectives which include; (1) examined the impact of sludge manure adoption on household crop production\, (2) investigated the welfare effect of sludge manure adoption among rural farm households and (3) evaluated the economic viability of using sludge manure in maize production. \nThe study employed a quasi-experimental design. Specifically\, Propensity score matching\, Endogenous switching regression and a partial budgeting analysis framework were employed as tools of analysis. The key results from this dissertation include; (1) sludge manure adoption leads to increased crop yields of say green bananas\, maize\, coffee and cassava crops (2) the results shows that using sludge manure improve per capita household food expenditure and per capita total household expenditure for adopters compared to non- adopters\, (3) applying sludge manure in the production of maize\, yields a higher marginal rate of return and this means that it is economically viable for household farmers to use sludge manure other than using inorganic fertilizers. In terms of recommendations\, the study recommends promotion of sludge manure as a pathway of increasing crop yields and eventually crop income which facilitates household welfare. Still\, since majority of smallholder farmers are financially constrained\, the use of sludge manure is recommended because it is cost effective in the production of crops like maize. \nSupervisors \nDr Aggrey Niringiye (PhD)\nSenior Lecturer\, Makerere University\, School of Economics. \nDr. John Sseruyange (PhD)\nLecturer\, Makerere University\, School of Economics \nVenue \n  \nYour presence and participation will be highly appreciated as we support the student in this important academic milestone. \n  \n

SUMMARY:PhD Public Defense for Mr.Isabirye Swaliki Kisige
DESCRIPTION:INVITATION: \nThe Dean\, School of Economics under the College of Business and Management Sciences (CoBAMS)\, cordially invites you to the PhD Public Defense of the following candidate: \nName of the Candidate: Mr. Isabirye Swaliki Kisige \nTitle of Thesis: \nExternal debt\, public and private investment\, and economic growth in Heavily Indebted Poor Countries in Sub Saharan Africa \nDate: Tuesday 4th August 2026. \nTime: 2:00pm – 5:00pm \nVenue: \nConference Room\, College of Business and Management Sciences\n(CoBAMS)\, Makerere University \nABSTRACT \nThis study examined how external public debt affects public investment\,\nprivate investment\, and economic growth in Highly Indebted Poor\nCountries within Sub-Saharan Africa over the period 2000 to 2024. The\nanalysis was guided by three objectives: to identify the determinants of\npublic investment with emphasis on external debt; to assess the effect\nof public investment on private investment and determine whether the\nrelationship is linear or nonlinear; and to examine the direct and\nindirect effects of external public debt on economic growth. \nTo address these objectives\, the study employed two complementary\neconometric approaches. The first objective was estimated using the\ntwo-step System Generalized Method of Moments estimator to account for\nendogeneity and dynamic fiscal behavior. The second and third objectives\nwere analyzed using the Pooled Mean Group estimator under the\nAutoregressive Distributed Lag framework\, given the evidence of long-run\nrelationships among the variables. \nThe results showed that public investment is influenced by its previous\nlevels\, meaning that once countries commit to infrastructure programmes\,\nthey tend to continue investing over time due to ongoing project and\npolicy commitments. Public investment was also shaped by external public\ndebt\, economic growth\, domestic revenue mobilization\, and political\nstability. External public debt exhibited a nonlinear effect: moderate\nborrowing supported public investment\, but once debt exceeded\napproximately 56 percent of GDP\, additional borrowing reduced the\ncapacity to finance new capital projects. \nPublic investment was found to stimulate private investment in the long\nrun\, confirming a complementary relationship. However\, this effect\nweakens once public investment surpasses an estimated threshold of about\n16 percent of GDP\, particularly where fiscal pressures are pronounced.\nFurthermore\, external public debt contributed positively to economic\ngrowth at low to moderate levels but demonstrated an inverted U-shaped\nrelationship at higher levels\, with the turning point occurring around\n23 to 24 percent of GDP. The results also revealed that debt contributes\nto growth only when it is directed toward productive investment rather\nthan consumption or debt servicing. \nOverall\, the findings underscore that public investment\, private\ninvestment\, and economic growth in HIPCs can benefit from external\nborrowing when debt levels remain within economically sustainable bounds\nand when borrowed resources are allocated to productive capital\nformation. The study recommends that governments in Sub-Saharan African\nHIPCs maintain public investment within the range of 10-12 percent of\nGDP\, where the crowding-in effect on private investment is strongest\,\nand avoid scaling investment beyond absorptive capacity. External public\ndebt should be kept below approximately 55 percent of GDP to preserve\nits supportive role in private investment\, and below 23-24 percent of\nGDP to avoid debt overhang effects on economic growth. Strengthening\npublic investment efficiency\, improving debt management frameworks\,\nexpanding domestic revenue mobilization\, and deepening domestic credit\nmarkets are therefore essential to ensure that external borrowing\ntranslates into productive capital formation and sustainable long-term\ndevelopment. \nSupervisors: \nDr. John Mutenyo\nDr. John Bosco Oryema \nYour presence and participation will be highly appreciated as we support the student in this important academic milestone.
