Deutschland sieht sich massiven handelspolitischen Herausforderungen gegenüber. In den vergangenen Jahren ging es dabei vor allem um den Umgang mit China hinsichtlich der Reduzierung von Abhängigkeiten sowohl auf der Export- als auch auf der Importseite. Seit der Amtsübernahme des neuen US-Präsidenten Donald Trump ist jedoch auch klar, dass die Handelsbeziehungen mit den USA wegen angekündigter Zölle und dem damit verbundenen Angriff auf die globale Handelsordnung zunehmend problematisch werden. Das alles findet vor dem Hintergrund einer Wachstumsschwäche der deutschen Wirtschaft statt[...]

How Importers Hedge Demand Uncertainty Through Dual Sourcing and Safety Inventory

29th January 2025
KCG Secretary
Authors: Chris Muris, Horst Raff, Nicolas Schmitt and Frank Stähler (Canadian Journal of Economics, forthcoming)

We develop a dynamic model of inventory and trade to study how an importer may hedge demand uncertainty when importing involves an order lead time. We show that when the import cost is low, the importer optimally holds safety inventory, i.e., inventory of imported goods in excess of expected sales to deal with demand surges[...]

Digitalization Intensity and Extensive Margins of Exports in Manufacturing Firms from 27 EU Countries – Evidence from Kernel-Regularized Least Squares Regression

The use of cloud computing by firms can be expected to go hand in hand with higher productivity, more innovations, and lower costs, and, therefore, should be positively related to export activities. Empirical evidence on the link between cloud computing and exports, however, is missing[...]
