We analyze the impact of a rise in protectionism on environmental regulation. Using the 2018 US-China trade war as a quasi-natural experiment, we find that higher exposure to tariffs leads to less stringent regulation targets in China, increasing air pollution and carbon emissions. Politically...

This paper analyses how international outsourcing affects plant productivity, with the major contribution lying in the identification of heterogeneous effects for firms with differing internationalisation status. The results point to a striking pattern: the status of being an outsourcer matters...

We study the impact of the Brexit referendum on Irish exporters to the UK. The referendum triggered a sharp devaluation of the British pound vis-a-vis the euro and led to considerable uncertainty about future trade relations between the UK and the EU. Using administrative data on the universe of...

While it is well-recognized that there are differences in the trade values reported by exporters and importers, a literature has emerged linking this trade gap to tariff evasion. These efforts, however, lack a structural theoretic underpinning and limit their product-level investigations to a...

This study examines the potential effects of China's "One-Belt One-Road" initiative (OBOR) on trade flows and global value chain connections. The empirical analysis is based on the augmented gravity model of international trade, which comprises 186 reporters and 199 partners in the period...

On April 2, 2025, President Donald Trump announced a wide-ranging set of "reciprocal tariffs" against many of its trading partners. The calculation of these tariffs have elicited a largely negative reaction in part due to the simple formula used to calculate them. In this note, I provide a model...

In this paper, we examine the similarities and the differences between two global problems, the Coronavirus pandemic and climate change, and the extent to which the experience with the Covid19 pandemic can be of use for tackling climate change. We show that both problems share the same...

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models. However, these models tend to rely heavily on symmetry assumptions and assume melting iceberg transport costs as the only form of trade restrictions. Moreover, a standard...

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models. This introduction has highlighted the importance of the entry/exit decision of firms in response to changes in trade barriers. However, it is typical in many of these...

We investigate the response of US trucking firms to the removal of barriers to crossborder trucking under NAFTA. This was done via a program implemented in 2007, cancelled in 2009, and reinstated in 2011. We find that, unsurprisingly, the program's start resulted in lower stock returns,...
