We study the role of firm heterogeneity and imperfect competition for global production networks and the gains from trade. We develop a quantifiable trade model with two-sided firm heterogeneity, matching frictions, and oligopolistic competition upstream. More productive buyers endogenously...

This paper examines the involvement of the CEECs into regional and global production networks over the period 1999 to 2009. We employ a theoretically justified gravity model which incorporates the extensive margin of trade and accounts for firm heterogeneity. We first estimate the model for...

The aim of the research presented in this paper is to assess the competitive potential of Polish agriculture (potential competitiveness) and the competitive position of the Polish agri-food sector on the Single European Market (SEM) with reference to the global context. The conducted research...

This paper examines the relationship between the shadow economy and trade openness in Uganda, using autoregressive distributed lag bounds testing approach. We find that the shadow economy and trade openness have a long- and short-run relationship. These results hold even when alternative...

This paper investigates Samuelson's (JEP, 2004) argument that technical progress of the trade partner may hurt the home country. We illustrate this prospect in a simple Ricardian model for sitations with outward knowledge spillovers. Within this framework Samuelson's "Act II" effects may occur....

In the absence of financial frictions, the purpose of thin capitalization rules is to limit multinational firms’ possibilities of engaging in tax planning via debt shifting. This paper analyzes the effects of thin capitalization rules in the case where firms have limited access to external...

Trade theory traces back different patterns of internationalization to heterogeneity between firms, measured both through differences in productivity levels and size. In this paper we analyze the link between heterogeneity within sectors and internationalization choices, namely trade and foreign...

The economic effects of a pandemic crucially depend on the extend to which countries are connected in global production networks. In this paper we incorporate production barriers induced by COVID-19 shock into a Ricardian model with sectoral linkages, trade in intermediate goods and sectoral...

The studies summarised in this paper focus on the economic implications of euro area firms' participation in global value chains (GVCs). They show how, and to what extent, a large set of economic variables and interlinkages have been affected by international production sharing. The core...
