This comprehensive analysis aims to determine socioeconomic, demographic, and location factors that influence various household expenditures in urban households in the Republic of Uganda. The three essays in this dissertation examine different categories of expenditures. The first essay analyses different household expenditures like food, fuel, education, clothing, transportation, etc., employing multivariate Tobit estimation to determine important influential factors. Second essay examines specific food expenditures, i.e., fresh fruit and vegetable expenditures using censored quantile regression to arrive at suitable policy implications. The last one examines the importance of socioeconomic factors in variation in the pattern of peanut paste consumption frequency by applying zero inflated Negative Binomial model. Results conclude that income elasticity of expenditures for fuel, education, and transportation are much higher, while that for food is very low. Income elasticity of expenditure for fresh fruits for households that fall in 25th quantile is slightly above one, indicating that an income support/ price discount may increase fresh fruit consumption in such households. Other factors like education, employment type, location, etc., also influence household expenditures. The household profiles created out of these results help policy decision makers both in public and private sectors to target segments of their interest when implementing programs.
