Gaëlle Simard-Duplain

I am a PhD candidate at the Vancouver School of Economics, University of British Columbia. My fields of interest are Labour Economics, Family Economics, and Public Economics.

In my job market paper, I study the effect of divorce and divorce risk on the labour supply of women at different points in their life-cycle. For this work, I helped create a new linkage between the Longitudinal and International Study of Adults (LISA) and the tax records of survey respondents’ past and present family members. I have also used this data to study intergenerational income mobility in Canada.

I am on the job market this year, and will be available for interviews at the 2018 CEEE (Toronto) and at the 2019 AEA/ASSA meetings (Atlanta).



Abstract: In this paper, I develop and estimate a model of life-cycle labour supply that incorporates the role of divorce. To do so, I set a collective model of household decision-making in an intertemporal context. The reduced-form literature has produced contradictory results on the effect of divorce and divorce risk on women's labour decisions. My model provides a unifying framework within which to view these findings. It also contributes to the structural literature, which has mostly studied how divorce alters bargaining power in marriage, and ignored women's insurance response to the risk of dissolution. I find that divorce shifts the lifetime expected income of married women, thus changing their labour in all periods. However, this effect is mitigated over time, as women stay in and learn about their marriage. At the time of dissolution, the inability to perfectly forecast the timing and impact of the event results in a negative income shock for most women. There is little evidence of subsequent lingering effects.

Abstract: In this paper, we exploit the Longitudinal Administrative Databank (LAD) to study the evolution of wealth inequality in Canada from 1982 to 2015, and its persistence for given individuals. Wealth inequality has received increasing attention over the past decade, spurred by a broad concern for justice, as well as an aging population that is increasingly dependent on its savings. In Canada, the study of wealth inequality has relied largely on the Survey of Financial Security and its predecessors. Although an invaluable resource, this data set has until recently only been collected every seven years or so, and its sample size limits the evaluation of inequality for subgroups of the population. However, it’s been shown with respect to income inequality that overall trends conceal important differences across regions and over time, differences that are crucial to our understanding of the role played by macroeconomic conditions and tax legislation. Our paper uses the income capitalization method to take advantage of the higher-frequency data and large sample size provided by the LAD. Furthermore, features of the Canadian tax system allow us to address some of the method’s limitations. Perhaps most importantly, the longitudinal nature of the data set makes it possible to study the persistence of wealth rankings over people’s lifetime. Consistent with the existing literature, we find that the share of the top 1%, especially the top 0.1%, grew substantially from the late 1990s to the mid-2000s, with more moderate growth thereafter. However, the probability for members of the top 1% to remain at the top decreased over the period covered.
