This paper uses firm level data from the World Bank Enterprise surveys conducted in 2019 and from the COVID-19 follow-up surveys conducted in 2020 in eight European countries to investigate the link between firm characteristics before the pandemic and firm survival until 2020. For the first time...

Firm characteristics in empirical models for margins of international trade usually enter these models in linear form. If non-linearities do matter and are ignored this leads to biased results. Researchers, however, can never be sure that all possible non-linear relationships are taken care of....

Increasing competition and reducing market power are core interests of economists, regulators and the public to maximise aggregate social welfare. Low prices are achieved through intense competition in the retail gasoline market. The absence of fierce competition is referred to as market power....

This (very short) note introduces nep-iaf, a new e-mail service that helps researchers interested in international activities of firms to stay up to date with newly published working papers on firms’ international activities, e.g. export, import, foreign direct investment, offshoring,...

Since 2016 the Journal of Economics and Statistics publishes the Data Observer section with descriptions of data that can be used in empirical research in economics (and in the social sciences in general), This note gives a short overview of the contributions published in the first ten years.

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,...

The use of digital technologies like artificial intelligence, robotics, or smart devices can be expected to go hand in hand with higher productivity and lower trade costs, and, therefore, to be positively related to export activities. This paper uses firm level data for manufacturing enterprises...

Für die Verbreitung der Elektromobilität in Deutschland sind die öffentlichen Ladepunkte mit entscheidend und dabei kommt es auch darauf an, zu welchen Preisen der Ladestrom bereitgestellt wird. Die Höhe der Ladepreise wird auch durch das Ausmaß an Wettbewerb an den Ladesäulen bestimmt....
