JDI names four Doctoral Fellows

The JDI has named four new Doctoral Fellows to receive JDI Dissertation Completion Stipends for the 2016-2017 academic year. The fellows are Andrea Craig, Michal Popiel, Sergei Shibaev, and Wenbo Zhu, all advanced PhD Candidates in the Department of Economics at Queen's University.

Andrea Craig is working on a dissertation titled "Equilibrium effects of transit policies on residential location."

With individual level data for Vancouver, I estimate a model of households choosing where to live and how to commute to work. I quantify how a proposed rapid transit line would affect income segregation, housing prices, transit ridership, and welfare. My analysis accounts for the transit line affecting where households live. This framework could be applied to other transit policies or cities.

Michal Popiel is working on a dissertation titled "Policy implications in the aftermath of the global financial crisis."

My research project studies the effects of fiscal and monetary policy in the context of new challenges brought on by the 2008 global financial crisis and its aftermath. I explore the transmission and effectiveness of unconventional monetary policy measures that were introduced when the interest rate reached the zero lower bound as well as the cross-country spillovers of these policies. I also examine the role of fiscal policy uncertainty as a potential contributor to the financial crisis as well as an impediment to the ensuing recovery. The goal of my research project is to provide empirical evidence relevant to policy makers as they reassess their toolbox of economic stabilizers.

Sergei Shibaev is working on a dissertation titled "Identifying and characterizing economically at-risk and distressed regions"

This research investigates small regional divisions to identify areas that would stand to benefit from industry-specific economic stimulus to prevent chronic economic distress. The analysis identifies geographical concentrations (spatial clusters) of potentially distressed regions and explains which industries drive their regional composition. The developed framework captures spatial interactions between regions and explores the importance of various geographic and economic factors.

Wenbo Zhu is working on a dissertation titled "Innovation, Income Inequality and Economic Growth."

The impacts of technological advancements are not neutral with respect to different factor inputs. In particular, some technological advancements tend to be skill-complementing (i.e. skill-biased), while some others tend to be skill-replacing (i.e. unskill-biased). Using a novel European data set, I measure these two types of technologies directly and establish the following empirical findings: (1) a sizable positive causal impact of skill-complementing relative to skill-replacing technologies on the skill premium; (2) the impact is more significant for female workers than for male workers; and (3) the level of substitutability between skill-complementing and skill-replacing technology is high. With the evidence above, I develop a model to investigate the possibility of explaining the increase in income inequality, the slowing down in labour productivity growth, and increase in product innovations at the same time, using the dynamics and the composition of different technological advancements. Moreover, I investigate the possible explanations to the gender difference result.
