This paper looks at the causes of increasing cost of living by studying two (2) main factors; frstly, the slow growth in income as compared to infation, and secondly the unproportional increase in standard of living as compared to income. For the frst factor, a time series regression model was constructred using the data from Household Income Survey report (various years) to compare the fuctutation in income against the infation rate year-on-year. For the second factor, we studied the expenditure elasticity of income for the household. A log-log linear regression model was developed taking into consideration the three (3) main groups of goods that household buys: Food, Transportation and Housing. We have studied the elasticities across income strata (B40, M40, T20) and location (Rural vs Urban) to observe the changes in elasticity with respect to those variables. The result of this study points that income growth has indeed surpasses infation rate from year to year, however the standard of living is increasing at a comparatively fast rate, as evidenced by high expenditure elasticities for several types of goods for B40s and M40s. This suggests that the standard of living, or living styles are the dominant factor that contributes to the problems of increasing cost of living.

Housing affordability has been an important issue for both developed and developing countries. Prior literature has used the price-income ratio as the main standard to assess housing affordability with the median disposable household income of the sample population commonly used. As such, conclusions drawn from macro-level analyses lack practical policy considerations. This paper attempts to address the problem in greater detail by considering age cohorts, income percentiles and different house types. The results show that for those aged 20-24 and 60-64, housing is severely unaffordable across all house types, except for the 75th income percentile group. The most expensive - semi-detached and detached housing types - remain unaffordable to all income and age groups, except for the 75th income percentile group aged 30 and above. Terrace and high rise housing types are the most affordable across each income percentile. Based on the results, we extend the housing affordability literature through recommendation of several policy measures that may ameliorate the affordability conundrum.
