Decomposition of various health outcomes in aging population (Draft), Fall 2016


This paper tries to find to what extent does aging population drive the number of people with different disease, health deficits or chronic illnesses (diabetes, asthma, respiratory diseases, arthritis, hypertension, bronchitis etc.), and how can it be measured. To analyze the sources of observed change in prevalence of any given disease (headcount), a simple decomposition formula proposed by Ravallion and Huppi (1991) will be used. This decomposition method is widely used in poverty and inequality literature. To avoid the limitations of head-count index (does not consider the severity of a given disease), frailty index is developed and used as well. Frailty scores from 0 to 1 are often assigned based on the number of health deficits present among the health indicators considered, with higher values denoting greater frailty. Frailty severity will be calculated based on cut-off point (=.21) suggested by Hoover, Rotermann, Sanmartin & Bernier (2003). This decomposition method provides some insights on whether there is any impact of changing age distribution (due to aging population) on the prevalence of various age related disease or symptoms and how aging population affecting overall distribution of a certain disease or symptoms.

Economic Assimilation of Canadian Immigrants, Fall 2015


Using Census Public Use Microdata File (PUMF) for years 2001, 2006 and 2011 (National Household Survey), this paper suggests that there is a deterioration of relative entry earnings for both male and female immigrants between 2000-2005. In 2000, the income of male immigrants who had arrived recently in Canada was 25% percent lower than Canadian-born men. In 2005, the earnings gap at entry jumped to 36%. Although there is an improvement (little decrease) in this gap by 2010 (to 29%), still it is higher than year-2000 level. The Same pattern is true for female immigrants and their counterparts. Moreover, recent immigrant cohorts are performing worse than their previous cohorts. But female immigrant’s performance is little better than their male counterpart. For example, female immigrants of 1980-1989 already catch up their Canadian-born counterparts in 2010. Results from OLS regression suggest that observable socioeconomic characteristics cannot explain the deteriorating entry earnings of recent immigrants. May be, returns to these characteristics have declined in recent times suggested by the other research. Specifically, immigrant entry earnings have fallen in part because of the broader decline in earnings among new entrants in the Canadian labor market (Frenette 2005). Results also show that assimilation is taking place, but I cannot conclude whether the speed of assimilation is increasing or decreasing over time. Recent immigrants start with earnings up to 24% lower than their Canadian-born counterparts and have assimilated at a very modest pace (around 10%) in their first years in Canada. If their future assimilation matches that of earlier cohorts, convergence with natives may be unattainable, because assimilation rate of earlier cohorts is relatively small (only 4.5% for 6-10 years experience and only 2% for 11-15 years experience cohort in 2010). Lower returns to experience for immigrant compared to native might have an offsetting effect on assimilation.

 Job satisfaction and health: In search of a casual relation, June 2008


Despite the fact that job satisfaction is considered as an important determinant of health status, very few supports has been presented for the opposite relationship. This project makes the use of British Household Panel Data, estimated ordered logit regression and fixed effect conditional logit regression over the 11 wave (1991-2002). Results from the two models show that health status has a significant impact on overall job satisfaction. Promotion opportunity in the present job has most significant impact on the overall level of job satisfaction. Holding a managerial position and being a government employee positively affect overall job satisfaction. Longer working hours reduces the employees job satisfaction level.
