Except tobacco farming, tobacco barn owners move to different income sources such as other crop cultivation and non-Agricultural activities due to clear differences in the living status. Therefore, this study aims to analyze the determinants of flue cured barn owner’s income diversification and share of income sources to total household income at Galewela, Polonnaruwa and Mahiyanganaya in Sri Lanka. The study drew a sample of 302 flue cured barn owners through random sampling technique from the three different regions and the data obtained were analyzed using descriptive statistics, Herfindhal diversification index and Censored Tobit regression. The results indicate that the level of income diversification among the flue cured tobacco barn owners in Sri Lanka depicted by the inverse of Herfindhal index is 3.02. According to Herfindhal index, the highest income diversification is observed in Mahiyangana area while the lowest income diversification is observed in Galewela area. The age of the barn owner, experience in tobacco cultivation, land ownership of the barn owner, total land availability (leased and tenure), capital goods ownership (tractors), tobacco specific resource endowment (number of barns), and distance to the nearest town were the major determinants of income shares from different sources of activities.

This paper investigates the determinants on income diversification using 300 tea small holders in Badulla, Passara, Hali-ela and Attampitiya tea inspector ranges. Multinomial logistic regression was used to analyze the determinants of income diversification. The results indicate that tea smallholders with old experienced educated household heads and more family labor diversify income into different sources. Number of schooling children, number of old dependents also stimulate income diversification while households with male household heads, lager land extent and presence of male and female members above the age of fifteen demotivate diversification activities. A censored Tobit regression model was used to find the determinants of the degree of income diversification measured by the Simpsons Index of Diversity (SID). Average value of SID is 0.296 indicating low level of income diversification in tea smallholders in Badulla District. Age and education level of the household head, family size, experience on tea cultivation, family labor availability, presence of children below age six are positive significant factors while land extent and land ownership are negative significant factors affecting degree of diversification.

The Impact of Remittances and Gender on Expenditure Pattern on Rural Households in Sri Lanka
(International Conference on Business and Information (ICBI – 2019), [Accounting, Finance and Economics], Faculty of Commerce and Management Studies, University of Kelaniya Sri Lanka, 2019) Dharmadasa, R.A.P.I.S.; Rathnayake, K.K.H.M.; Samaraweera, W.G.R.L.
This study examines the impact of migrant remittances on expenditure pattern of rural households in Sri Lanka. Using a nationally representative data set, fractional logit models were estimated within the Engel curve framework for female headed and male headed households in order to examine the relationship between gender, remittances and expenditures of the rural households. The results suggest that with the receipt of internal remittances, male household heads allocate less on education and more on ad hoc purchases, entertainment and transport expenditure, while female household heads allocate more on food expenditure. The results further reveal that international remittances do not provide significant impact on household expenditure pattern in the rural sector households. Moreover, remitters’ contribution for the ad hoc purchases, entertainment and transport expenditure increases while their presence as a migrant to the household head. Based on the results, the research concludes that there is an association between receipt of remittances and expenditure pattern of rural Sri Lankan households and also the gender of the household head and expenditure pattern of rural Sri Lankan households.
