This study pushes our understanding of research reliability by reproducing and replicating claims from 110 papers in leading economic and political science journals. The analysis involves computational reproducibility checks and robustness assessments. It reveals several patterns. First, we...

Using data on all vehicles registered in Canadian provinces from 2000-2010, we estimate the elasticity of the fuel economy of the new vehicle stock with respect to gasoline price. We demonstrate that a 10% increase in gasoline price causes a 0.8% improvement in the fuel economy of new vehicles....

New vehicle feebate programs encourage improved fleet-wide vehicle fuel efficiency; yet analyses of these policies have been limited to ad hoc proposals. In this paper, we exploit an extensive, multi-year dataset which includes more than 16 million observations to evaluate the welfare...

Applying methods of textual and stylometric analysis to all 119,225 speeches made in the Canadian House of Commons between 2006 and 2011, we establish that air pollution reduces the speech quality of Canadian Members of Parliament (MPs). Exposure to fine particulate matter concentrations...

This study evaluates the implications of an actual carbon tax on international trade in the agricultural sector. Applying uniformly to all fossil fuels combusted within its borders, the province of British Columbia unilaterally introduced a carbon tax on July 1, 2008. In 2012, the province...

We demonstrate that the carbon tax imposed by the Canadian province of British Columbia caused a decline in short-run gasoline demand that is significantly greater than would be expected from an equivalent increase in the market price of gasoline. That the carbon tax is more salient, or yields a...

De Haas and Popov (2023) estimate the effect of country-level financial sector size and structure on decarbonization to show that countries with relatively more equity versus debt financing have more emission-efficient economies. We uncover multiple coding errors that change the magnitude and...
