This paper highlights an underexplored margin of heterogeneity that shapes resilience to disruptions in global maritime trade - the differential reliance of countries and sectors on specific categories of vessels. We combine US bills of lading records with ship registry and AIS-based port call...

This paper highlights an underexplored margin of heterogeneity that shapes resilience to disruptions in global shipping - the differential reliance of countries and sectors on specific categories of vessels. We combine US bills of lading records with ship registry and AIS-based port call data to...

We consider five models of international trade that belong to the class of models in which the trade elasticity and domestic trade share are sufficient statistics for the welfare cost of autarky. Three are fixed-variety models featuring increasing micro-level margins of adjustment: versions of...

This paper develops a dynamic real-options model of tariff deterrence in which the exporting country, though subject to the importing country's market power, assumes the role of leader in a Stackelberg framework under uncertainty by acting preventively to dissuade the importer from imposing a...

Peter Neary, a master of the understanding of international trade, and an international leader in the organization of the economics profession, is generally regarded as the greatest Irish economist of modern times. Known for the elegant rigour and precision with which he presented the arguments...

The aim of the article is to show that although most countries in the Global South have been able to reduce absolute poverty, with a few exceptions they have not succeeded in catching up with the countries of the Global North. The conclusion of the article is that, especially after the...

A successful energy transition requires systemic changes and long-term investment in energy, heating and mobility systems. It must be implemented successfully at a regional level. To demonstrate the regional impact, detailed modelling of regional conditions is necessary. To this end, we have...

So-called "connector" countries have been argued to benefit from the US-China trade tensions, given their rising share in US imports. This paper draws an important distinction between trade reallocation-countries increase domestic production to substitute for declining Chinese exports to the...

We develop a two-country model of international trade featuring non-homothetic preferences and income inequality, generating a price schedule where cheap necessities coexist with expensive luxury goods. A central mechanism driving price differences is firm's ability to shift fixed costs between...

We explore the impact of export quality on the levels of exports and domestic trade. First, we developed a theoretical framework, using the two-country oligopolistic model with quality differentials in product. We find that a consumer-preference driven increase in export quality improves export...

In 2011, the American Economic Association (AEA) changed its peer review policy for all their journals, shifting from a double-blind process to a single-blind peer-review process. Under this new system, referees became aware of the authors' identities. In this paper, I explore whether this...

The new US administration has a clear agenda of reducing imports to the US and attract FDI by reducing tariffs and using the proceeds for supporting investment in the US. This paper uses a dynamic two country US vs RoW model where monopolistically competitive firms make export and FDI decisions....

In 2018 and 2019, the US administration increased tariffs on imports from China. Did these tariffs lead to more US imports from other countries such as Mexico? Using highly disaggregated data on the universe of Mexican firm-level exports, we find evidence of trade diversion from China to Mexico....

We study how demand uncertainty affects risk-neutral firms. number of export destinations when uncertainty is resolved after firms choose their export destinations and output. We show that firms’ ability to allocate their output across destinations in response to destination-specific shock...

We study how demand uncertainty affects risk-neutral firms' number of export destinations when uncertainty is resolved after firms choose their export destinations and output. We show that firms' ability to allocate their output across destinations in response to destination-specific shock...

This paper introduces a novel mechanism by emphasizing benefits for firms through participation in buyer networks among firms that source the same locally produced inputs. In a first step, we utilize register-based data from Denmark to generate a firm-specific buyer network variable which relies...

We study how tariffs affect industrial structure and welfare in an economy where sectors are complements and preferences are nonhomothetic-two drivers of structural change. Import tariffs on a sector influence sectoral composition by affecting its price relative to other sectors and national...

This paper investigates the determinants of comparative advantage in Artificial Intelligence (AI)-intensive industries using a comprehensive dataset of US imports from 68 countries across 79 manufacturing and service industries over the period 1999-2019. Using a novel measure of AI intensity...

We examine how tariffs affect sectoral composition and welfare in an economy with nonhomothetic preferences and sectors being complements---key drivers of structural change. Beyond their conventional role in trade protection, tariffs influence industrial structure by altering relative prices and...
