Cloud computing and extensive margins of exports: Evidence for manufacturing firms from 27 EU countries

8th May 2024
KCG Secretary
Authors: Joachim Wagner (Journal of Information Economics 2024 2(1): 102–111)

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[...]

KCG Working Paper No. 32: Estimation of empirical models for margins of exports with unknown non-linear functional forms: A Kernel-Regularized Least Squares (KRLS) approach

Author: Joachim Wagner

Empirical models for intensive or extensive margins of trade that relate measures of exports to firm characteristics are usually estimated by variants of (generalized) linear models. Usually, the firm characteristics that explain these export margins enter the empirical model in linear form, some-times augmented by quadratic terms or higher order polynomials, or interaction terms, to take care or test for non-linear relationships.

KCG Working Paper No. 28: Big Data Analytics and Exports – Evidence for Manufacturing Firms from 27 EU Countries

22nd September 2023
KCG Secretary
Author: Joachim Wagner

The use of big data analytics (including data mining and predictive analytics) by firms can be expected to increase productivity and reduce trade costs, which should be positively related to export activities. This paper uses firm level data from the Flash Eurobarometer 486 survey conducted in February – May 2020 to investigate the link between the use of big data analytics and export activities in manufacturing enterprises from the 27 member countries of the European Union[...]
