The main objective of this research is to identify the impact of social media addiction on the labour supply of employees in Sri Lanka. The study covers 390 employees through a questionnaire survey. The study used the endogenous switching regression model for modelling average working hours per week day of social media addicts and non-addicts comparatively. Age, marital status, executive employment, type of social media and commuting distance to the workplace are the key factors associated with social media addiction of workers as in the selection function of the model. Working hours of social media addicts are affected by age, gender and executive employment while the working hours of non addicts are mainly affected by gender, marriage, executive employment, years of education and monthly net salary. Social media addiction of non addicts causes reduction of average hours of work per week day, while hours of work of social media addicts increase, if they have given up social media addiction. Institution specific policy insights are also proposed to increase the performance of employees.

The tire industry in Sri Lanka shows excellent potential for the development of the economy with a substantial contribution to export income. Therefore, the main objective of this study is to examine the determinants and impact of tire export income in Sri Lanka. Secondary data was obtained from Central Bank in Sri Lanka and United Nations Statistical Office covering the period from 1989 to 2018. Unit root test, simple and multiple regression Co integration analysis, Error Correction Model, and Granger Causality tests were used for analysis. The study found a long-run causality between GDP, Global market price for rubber, Exchange Rate, and Inflation with tire export income. The causality test suggested a causality running from export income to GDP. However, there is no causality running between GDP and export income. According to regression results, GDP, inflation, and exchange rate significantly determined the tire export income in Sri Lanka. Further, inflation and exchange rates were negative, and the GDP was positively influenced by the tire export income. While Domestic and Global Market prices for rubber did not show a significant influence on the tire export income. Government should maintain favourable macroeconomic policies, especially monetary policies which enhance the stability of the economy.

Medical care is an input to the production of health. People get treatment for their health issues under western medicine , complementary and alternative medicine. Western medicine can be identified as the most famous and modern medical care system in the world. Complementary and alternative medicine refers to a variety of health practices as ayurveda, homeopathy, acupuncture, herbs, yoga, etc. Considering Sri Lankan context, with the rapid increase of ageing population, there is a growing trend in non communicable diseases. Most of people tend to use these two systems to recover from non communicable diseases as asthma, cholesterol, hypertension, arthritis, etc. The main objective of this study was to distinguish between the demand for alternative medicine and western medicine related to non communicable diseases. It was considered socio demographic and economic factors for demand in medical care for both sectors. Primary data was based on Arogya private hospital and Siddhayurvedini private ayurvedic care institution in Gampaha. It was selected 100 non communicable disease patients using systematic sampling method. Logistic regression model was mainly used to distinguish between the alternative and western medical care. According to the findings of this study, females are more likely to demand for both medical cares. Middle age, unemployed, arthritis patient and duration of disease 2-5 years cause to raise demand for alternative medical care. Diabetic patient, employed, believing health status as serious and having employer provided insurance cause to raise demand for western medical care. Relative to the demand for alternative medical care, living in rural area and lower educated people are negatively associated with demand for western medical care.

Purpose: This study aims to explore the role of the banking sector in elevating the economic growth of Sri Lanka by identifying the short-run and long-run relationship between banking sector development and economic growth in Sri Lanka.Design/Methodology/Approach: This study uses annual data for the period 1960 to 2019 from World Bank's Global Financial Development Database and World Development Indicators. Odedokun's model, which assumes the causation between financial development to economic growth, is employed using the bound test within the ARDL framework.Findings: The estimated long-term parameter of the banking industry development indicator was found to be positively affected economic growth by supporting supply-led growth model. The estimations of the Error Correction Model provide a broad picture of the short-term relationship, and the results are highly consistent with the results of the long-term model. Granger Causality test found that the banking sector development granger cause to the GDP indicating a unilateral relationship.Originality: This study differs from the existing studies, which focus on the neoclassical one-sector aggregate production model. Financial development is input along with other real sector variables to identify the short-run and long-run relationship with the help of a newly developed econometric approach.

Since its independence, Sri Lanka has had a free health care policy, and outof-pocket healthcare expense has increased over time. The study's primary goal is to investigate the factors influencing out-of-pocket healthcare spending in Sri Lanka. Secondary data from the Household Income and Expenditure Survey conducted by the Department of Census and Statistics in Sri Lanka in 2016 were used in this study. Data were analyzed using descriptive statistics and the Semi-Log regression model. The results of the Semi-Log regression model show that households with the urban residential sector, post-secondary education, and chronic conditions were significant positive predictors of out-of-pocket healthcare expenditure, while households with primary education were substantial negative predictors. Distance to maternity clinics has a strong beneficial influence on healthcare expenditure on the supply side. As a result, the findings demonstrate a compelling need to mitigate the adverse effects of growing healthcare costs. The government can enact new rules and regulations to protect households' ability to meet their healthcare needs by offering all healthcare facilities and expanding health infrastructure.
