We examine the impact of policy uncertainty on trade, prices, and real income through firm entry investments in general equilibrium. We estimate and quantify the impact of trade policy on China’s export boom to the United States following its 2001 WTO accession. We find the accession reduced the US threat of a trade war, which can account for over one-third of that export growth in the period 2000–2005. Reduced policy uncertainty lowered US prices and increased its consumers’ income by the equivalent of a 13-percentage-point permanent tariff decrease. These findings provide evidence of large effects of policy uncertainty on economic activity and the importance of agreements for reducing it.

We build into a Ricardian model sectoral linkages, trade in intermediate goods, and sectoral heterogeneity in production to quantify the trade and welfare effects from tariff changes. We also propose a new method to estimate sectoral trade elasticities consistent with any trade model that delivers a multiplicative gravity equation. We apply our model and use our estimated elasticities to identify the impact of NAFTA's tariff reductions. We find that Mexico's welfare increases by 1.31%, U.S.'s welfare increases by 0.08%, and Canada's welfare declines by 0.06%. We find that intra-bloc trade increases by 118% for Mexico, 11% for Canada, and 41% for the U. S. We show that welfare effects from tariff reductions are reduced when the structure of production does not take into account intermediate goods or input-output linkages. Our results highlight the importance of sectoral heterogeneity, intermediate goods, and sectoral linkages for the quantification of the welfare gains from tariffs reductions.

The recent U.S.–China trade conflicts cast new light on the role of trade policies in global value chains (GVCs). Contrary to the expectation that trade restrictions lead to the shrinking or disruption of GVCs, our article posits that the unintended consequences of trade policies (both restrictions and trade agreements) are amplified by the prevalence and organizational complexity of GVCs. We anchor our argument in the historical evolution of three classic GVCs – apparel, automobiles, and electronics – from the 1970s to the present. Our framework highlights the dynamic interaction between GVC-oriented trade policies and firm strategies, which often has counterintuitive implications in terms of upgrading outcomes for the countries and companies involved in these GVCs. While trade policies often provide momentum for an adaptive reconfiguration of GVCs, firms’ strategic actions are crucial in modifying the geographic and organizational features of GVCs in ways that support their longevity. Firm strategies can mediate the effect of trade policies on GVC configurations in two ways: (1) firms can accommodate trade restrictions and trade agreements by altering supply and demand locations and by switching supply-chain partners; and (2) firms pursue diverse strategies to upgrade their value chain activities, leveraging the shifting geographies associated with new trade rules.

This paper estimates a structural dynamic equilibrium model of the Brazilian labor market in order to study trade-induced transitional dynamics. The model features a multi-sector economy with overlapping generations, heterogeneous workers, endogenous accumulation of sector-specific experience, and costly switching of sectors. The model's estimates yield median costs of mobility ranging from 1.4 to 2.7 times annual average wages, but a high dispersion of these costs across the population. In addition, sector-specific experience is imperfectly transferable across sectors, leading to additional barriers to mobility. Using the estimated model for counterfactual trade liberalization experiments, the main findings are: (1) there is a large labor market response following trade liberalization but the transition may take several years; (2) potential aggregate welfare gains are significantly reduced due to the delayed adjustment; (3) trade-induced welfare effects depend on initial sector of employment and on worker demographics such as age and education. The experiments also highlight the sensitivity of the transitional dynamics with respect to assumptions regarding the mobility of capital.

The paper explores the evolution of export diversification patterns along the economic development path. Using a large database with 156 countries over 19 years at the HS6 level of disaggregation (4,991 product lines), we look for action at the intensive and extensive margins. We find a hump-shaped pattern of export diversification similar to what Imbs and Wacziarg (2003) found for production. Diversification and subsequent reconcentration take place mostly along the extensive margin. This hump-shaped pattern is consistent with the conjecture that countries travel across diversification cones, as discussed in Schott (2003, 2004) and Xiang (2007).

Tariffs are generally assumed to depend on the product, not the identity of the importer. However, special economic zones are a common, economically important policy used worldwide to lower tariffs on selected goods for selected manufacturers. I show this is motivated by policymakers’ desire to discriminate across buyers when a tax is intended to raise prices for sellers, through a mechanism distinct from existing theories of optimal taxation. Using a new dataset compiled from public records and exogenous changes in imports of intermediate goods, I find the form, composition, and size of US zones are consistent with the theory.

In 2013, China's growing economic capacities motivated Beijing to launch a multilateral bank to advance its diplomatic agenda. Scholars are still debating precisely what Beijing seeks to accomplish through the Asian Infrastructure Investment Bank (AIIB). This article surveys the key literature on the AIIB, identifying twenty scholarly interpretations of Beijing's strategic goals. The purpose of this research is to understand Beijing's initial design for this bank and evaluate whether this new multilateral development bank can function as an effective instrument for Beijing's economic statecraft. Over its first five years, as an economic tool for Beijing, the AIIB has performed quite remarkably well. The bank not only operates smoothly, generating a reasonable amount in net income for its shareholders, but also serves Beijing's strategic purposes in expanding China's regional influence, enhancing its international status, and ascending toward global leadership.

The Belt and Road Initiative (BRI) is an important policy agenda undertaken by the Chinese government. We explore how the BRI – as well as an associated policy, the creation of Chinese overseas special economic zones – influences Chinese outward foreign direct investment (FDI). We find that host-country institutional fragility positively influences Chinese FDI volumes, and that the impact of institutional fragility on Chinese inward FDI to the host is amplified in the presence of the BRI. Specifically, BRI policy facilitates FDI to countries with weaker rule of law and less government accountability. We argue that, while the BRI may actively facilitate economic growth (i.e., via infrastructure development), and in turn aspects of human development, particularly in less-developed economies, its likely impacts on political rights may not be so promising.

The previous studies of exports performance in Fiji were carried out at the aggregate level. We conduct a disaggregated analysis of exports of three major products, namely, sugar, tourism, and gold. This analysis is useful for developing sector-based export promotion policies. The long run as well as dynamic export demand functions are estimated at the aggregate and disaggregate levels. The results identify a number of factors such as trading partner income, relative prices, productivity shocks, natural disasters, political disturbances, and the exchange rate that affect the export demand for sugar, tourism, and gold, though not in the same way. For instance, tourism and sugar enjoy the highest income elasticity. Sugar export is adversely affected by natural calamities and political upheavals. The political upheavals also affect tourism adversely in Fiji. The exchange rate affects the export of sugar more than others. The idea that devaluation will promote exports in Fiji needs careful investigation because results show that this will happen with a high cost, i.e. 5% nominal devaluation will be required to increase real exports by 1%.

Carbon-based import tariffs are proposed as a policy measure to reduce carbon leakage and increase the global cost-effectiveness of unilateral CO2 emission pricing. We investigate the case for carbon tariffs. For our assessment, we combine multi-region input–output and computable general equilibrium analyses based on data from the World Input–Output Database for the period 2000–2014. The multi-region input–output analysis confirms that carbon embodied in trade has increased during this period, but trade flows from Non-OECD to OECD countries became less important in relative terms since the 2007–2008 financial crisis. The computable general equilibrium analysis suggests that carbon tariffs’ efficacy in combating leakage increases in periods when trade in carbon increases. However, its potential to improve the global-cost effectiveness of unilateral emission pricing remains modest. On the other hand, we find that the potential of carbon tariffs to shift the economic burden of CO2 emission reduction from abating developed regions to non-abating developing regions increases sharply between 2000 and 2007, but declines after the financial crisis.
