Does trade within a country affect welfare and productivity? What are the magnitude and consequences of costs to such trade? To answer these questions, we exploit unique Canadian data to measure internal trade costs in a variety of ways – they are large, and vary across sectors and...

International trade increases productivity; internal trade should too. The size and consequences of internal trade barriers are unfortunately not well known. Using unique Canadian data and multiple approaches to measure trade costs, we find internal trade barriers are large, especially for poor...

This paper studies the implications of household heterogeneity for trade. I develop a model where household heterogeneity is induced via incomplete markets and results in heterogeneous price elasticities. Conditional on exposure to trade, heterogeneous price elasticities imply that different...

Standard models of the new trade and location theories usually assume full employment and are thus ill-equipped to study spatial unemployment differences, which in reality are more pronounced that income disparities. Regional labour market theories like the ´wage curve´-approach on the other...

We examine the effects of globalization on the size and composition of tax revenues, worker-specific tax burdens, and effective average labor income tax rates using a unique international database on income tax calculators. We find that due to increasing mobility of firms and high-income...

What can economists learn from dynamic partial control of chemical reactors? Both chemical reactors and the economy involve many variables that are difficult to fully predict or control. Thus, this paper suggests the use of partial control, which involves indentifying only the key variables that...
