Economic integration in Europe has had ambiguous effects on industry concentration. The literature has proposed various explanations of the empirical findings. The present paper provides an additional theoretical argument. We show that in a world of monopolistic competition, integration in it...

Recent literature on the workhorse model of intra-industry trade has explored heterogeneous cost structures at the firm level. These approaches have proven to add realism and predictive power. This paper presents a new and simple heterogeneous-firms specification. We develop a symmetric...

Recent rounds of GATT and later WTO have advocated widespread tariffication, meaning that existing non-tariff barriers be converted into import equivalent tariffs. From an economic point of view, the effects of such tariffication are not entirely clear. The paper presents a general equilibrium...

Die GATT- und später WTO-Runden der letzten Jahre haben eine weitgreifende Tarifizierung durchgesetzt. Das bedeutet, dass existierende nicht-tarifäre Handelsbarrieren in Volumen-äquivalente Zölle konvertiert werden. Das Motiv einer solchen Maßnahme ist eine größere Transparenz der...

This essay deals with the issues of privatisation and restructuring in transition economies. The topics are addressed in both a descriptive and empirical manner. The centre of the analysis is the interrelation of privatisation, the resulting ownership form and the expected and actual effect on...

Why is it that exporter productivity premia (EPP) differ so widely in size? We take this question to the theory and to the data. We derive the sectoral EPP in a standard heterogeneous firms trade model and apply the insights from the model to 13 years of data for all Danish manufacturing firms....

An astonishing 33% of all firm-product-destination export spells in Danish data turn out to be isolated single-month one-off export events (observed once in a 49 month window). On average, for an export-active firm, such one-off exports account for 17% of total foreign sales. These patterns...

The present paper examines trade liberalization driven by the coordination of product standards. For oligopolistic firms situated in separate markets that are initially sheltered by national standards, mutual recognition of standards implies entry and reduced profits at home paired with the...
