This paper studies the origins and consequences of international technology gaps. I develop an endogenous growth model where R&D efficiency varies across countries and productivity differences emerge from firm-level technology investments. The theory characterizes how innovation and learning...

Dieser Beitrag soll einen Überblick und eine Systematik im Hinblick auf die aktuellen Beiträge zum Phänomen der Fragmentierung geben. Während man im Zusammenhang mit der Ausweitung des Nord-Süd-Handels von einer "horizontalen Globalisierung" spricht, gilt Fragmentierung als Ausdruck einer...

We estimate productivities at the sector level for 72 countries and 5 decades, and examine how they evolve over time in both developed and developing countries. In both country groups, comparative advantage has become weaker: productivity grew systematically faster in sectors that were initially...

I consider how heterogeneity in capital goods affects international trade patterns, and I show a novel source of comparative advantage: the magnitude of capital goods heterogeneity. Capital goods are heterogeneous in their vintage and productivity, and due to capacity constraints, only...

We illustrate a new source of comparative advantage that is generated by countries’ different ability to adjust to technological change. Our model introduces substitution of workers in codifiable (routine) tasks with more efficient machines, a process extensively documented in the labor...

This paper investigates the nature and pattern of export specialization in Lithuania. The aim of this paper is to estimate the nature and pattern of Lithuanian export specialization under existing conditions. Seeking to define the nature and pattern of export specialization, the basic methods of...

International trade in capital goods has quantitatively important effects on economic development through capital formation and TFP. Capital goods trade enables poor countries to access more efficient technologies, leading to lower relative prices of capital goods and higher capital-output...

We develop a dynamic trade model with comparative advantage, heterogeneous firms and workers and endogenous firm entry to study wage inequality during the adjustment to trade liberalization. We find that trade liberalization increases wage inequality both in the short run and in the long run. In...

Three features of China's trade patterns suggest that elements beyond factor abundance explain its export performance. The high penetration in world markets of labourintensive products has been accompanied by: (i) a high share in exports of productivityadvanced foreign-owned enterprises (FIEs),...

We introduce unemployment and endogenous selection of workers into different skill-classes in a trade model with two sectors and heterogeneous firms. This allows us to study the distributional consequences and the skill-specific unemployment effects of trade liberalization. We show that the...
