Climate change mitigation faces two main policy challenges: the need for global cooperation to tackle the collective action problem and the need to share the burden of global carbon pricing fair way following the principle of common but differentiated responsibility (CBRD). In this paper we...

Disruptions to global value chains (GVCs) - caused by conflicts, natural disasters, and accidents that close transport routes - and that affect specific regions or sectors, are not unusual. However, in recent years and amid the Covid-19 pandemic, they have become more frequent and severe. High...

The rapid rise in global fragmentation - foreign investment, global supply chains, and 'production sharing' - is fundamentally reshaping the multilateral trading system. This paper uses a simple economic modeling framework to understand how the global fragmentation phenomenon may reshape the...

Most international commerce is carried out by multinational firms, which use their foreign affiliates for the majority of their foreign sales. In this paper, I examine the determinants of multinational firms' location and production decisions and the welfare implications of multinational...

This paper analyses the role of services in international trade through the lens of global value chains (GVCs). Services account for more than 70% of world GDP but only for around 20% of world trade in balance of payments terms. In value added terms, accounting for services embodied in exported...

Geopolitical conflicts have increasingly been a driver of trade policy. We study the potential effects of global and persistent geopolitical conflicts on trade, technological innovation, and economic growth. In conventional trade models the welfare costs of such conflicts are modest. We build a...

In theory, e-commerce marketplaces connect buyers and sellers, open trade opportunities, and reduce transaction costs thereby creating opportunities for more inclusive trade and even GVC participation, especially for micro, small and medium-sized enterprises (MSMEs). Further, there is some...

Since the outbreak of the COVID-19 pandemic there has been a discussion among researchers and policy makers about changes to global value chains, both about expected changes and changes that should be promoted by government policies. In this paper we conduct an in-depth analysis of the reasons...

Two far-reaching developments have increased the trade opportunities for SMEs in developing countries. Firstly, the rise of the internet and advances in ICT have reduced trade-related information and communication costs. Secondly, the international fragmentation of production has increased the...

The geography of global value chains (GVCs) depends crucially on trade costs between countries hosting various stages of production. Some stages might be more sensitive to trade costs than others. In this paper, we exploit a value-added decomposition of bilateral trade flows to distinguish low...
