download_control_global

The function downloads search volumes from Google Trends for a control
batch in a set of locations. Data is automatically written to table
data_control. For <code>download_control_global</code> the input
location is automatically set to world.

Google offers public access to global search volumes from its
search engine through the Google Trends portal. The package downloads
these search volumes provided by Google Trends and uses them to
measure and analyze the distribution of search scores across countries
or within countries. The package allows researchers and analysts to
use these search scores to investigate global trends based on patterns
within these scores. This offers insights such as degree of
internationalization of firms and organizations or dissemination of
political, social, or technological trends across the globe or within
single countries. An outline of the package's methodological
foundations and potential applications is available as a working
paper: <https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3969013>.
