Lobbying and Political Risk Disclosure: Do Socially Responsible Firms Voluntarily Disclose More?
Abstract Drawing on theories of strategic communication, legitimacy, impression management and moral capital, this study investigates whether firms use political risk disclosure to offset negative perceptions associated with corporate lobbying. Using a sample of 10,120 observations from 1362 US firms between 2002 and 2018, we find that firms with ...

When Jobs Change: Skills Mismatch and the Value of Training
ABSTRACT This article examines the impact of rapidly changing skill requirements on skills mismatch in Europe and the role of training in mitigating adverse effects. Using data on approximately 70 million online job vacancies, we estimate the extent to which occupational skill requirements changed between 2019 and 2023 across European Union (EU ...
