This dissertation examines four disadvantaged groups in the labour market from a variety of perspectives. Specifically, I looked into older workers, younger workers, nonstandard workers and female workers. In the first chapter, I examine the effects of Ontario eliminating mandatory retirement in 2006 on the labour force participation of older workers and the unemployment of younger workers. My second chapter examines the relationship between nonstandard employment and the subsequent workplace profitability. In my final chapter, I examine the interaction effect of employment status and gender on the issue of work hour mismatches. The first chapter examines the impact of recent labour policy change at a national/provincial level. I find positive and significant effects for the labour force participation rate of older workers in Ontario in the five years following the legislation change of banning mandatory retirement in Onatrio. Similar results are found for both men and women; however, the magnitude of this effect is somewhat smaller for men. In addition, the empirical analysis also reveals a short-run rise in the unemployment rate of younger workers. The second chapter examines the financial implication of nonstandard employment at an organizational level. The results suggest that nonstandard employment is positively associated with subsequent workplace profitability, after controlling for factors that might also affect profitability. Moreover, this significant positive relationship between nonstandard employment and subsequent profitability is primarily driven by capital intensive manufacturing, the real estate/rental/leasing, the retail/trade/consumer service, and the education and health services industries as well as smaller workplaces. Larger workplaces and the rest of the private sector do not display significant results. The final chapter looks into how employment status and gender systematically impact work hour preferences at an individual level. The findings indicate that there is a significant interaction effect between nonstandard employment and gender. Female nonstandard workers prefer to work more hours. Male workers, both nonstandard and standard, are more likely to prefer to work fewer or the same hours. These results conform to labour market trend of increasing labour force participation rates of females and a declining trend among males.
