This research examines the effect on macroeconomic determinants on welfare and social wellbeing in Oman. In this study the impacts of inflation, wages, unemployment and openness of welfare - GDP per capita (current local currency)- in Oman are estimated using the Pearson correlation coefficient to find the nature of the relationship between them. Gini index was added to see if it has any impact on the welfare. The study showed that inflation, wages and openness, with over 90% correlation, positively and directly affect welfare. Unemployment showed a negative relationship with the same variables. The policymakers of the country should put more priority on reducing the unemployment rate rather than on restraining inflation, and give more freedom for international trade (which may create more jobs and lead to an increase in wages).
