We embed a model of the labor market with sector-specific search-and-matching frictions into a Ricardian model with a continuum of goods to show that trade reduces unemployment in countries with comparative advantage in sectors with more efficient labor markets and leads to higher unemployment...

We embed a model of the labor market with sector-specific search-and-matching frictions into a Ricardian model with a continuum of goods to show that trade liberalization causes higher unemployment in countries with comparative advantage in sectors with strong labor market frictions and leads to...

This paper presents a simple framework in which the location and the growth rate of economic activities are endogenous and interact. We show that the nature of the equilibrium and of the relation between growth and location depends fundamentally on whether capital is assumed to be mobile (in...

We design a spatial model featuring workers embodied with heterogeneous skills. In equilibrium, locations with improved market access become relatively more attractive to the high-skilled, high-income earners. We then empirically analyze the effects of the construction of the Swiss highway...

We construct a new dataset containing parcel sizes and building footprints of Canadian manufacturing plants and decompose industrial density (parcel size per worker) into: crowding (floorspace per worker); building height (floorspace to building footprint); and parcel coverage (building...

We combine census and establishment-level data for 2001-2017 to study the impact of mass layoffs of big manufacturing plants on city-level population and its composition in Canada. We find that manufacturing plant closures and downsizing lead to a decline in subsequent population growth,...

We develop a new general equilibrium model of trade with heterogeneous firms, variable demand elasticities and endogenously determined wages. Trade integration favors wage convergence, intensifies competition, and forces the least efficient firms to leave the market, thereby affecting aggregate...

The world is replete with spatial frictions. Shipping goods across cities entails trade frictions. Commuting within cities causes urban frictions. How important are these frictions in shaping the spatial economy? We develop and quantify a novel framework to address this question at three...

We study the determinants of agglomeration of Canadian manufacturing industries from 1990 to 2009. In so doing, we revisit the seminal contribution by Rosenthal and Strange (2001, "The determinants of agglomeration", J Urban Econ 50(2), 191?229) using a long panel and continuous measures of...

We develop a model of a city populated by heterogeneous agents. Agents self-select into entrepreneurship, and entrepreneurs set up firms which hire workers. We characterize the equilibrium matching between firms and workers, as well as the within-city assignment of agents to locations. We then...
