Notes
Reported row and column totals from source data are not stored.
Module Contents¶
- mergeron.core.ftc_merger_investigations_data.WORK_DIR[source]¶
Redefined, in case the user defines WORK_DIR betweeen module imports.
-
mergeron.core.ftc_merger_investigations_data.TABLE_TYPES =
('ByHHIandDelta', 'ByFirmCount')[source]¶
- mergeron.core.ftc_merger_investigations_data.invert_map(_dict)[source]¶
Invert mapping, mapping values to keys of the original mapping.
-
mergeron.core.ftc_merger_investigations_data.construct_data(_archive_path=
INVDATA_ARCHIVE_PATH, *, flag_backward_compatibility=True, flag_pharma_for_exclusion=True, rebuild_data=False)[source]¶ Construct FTC merger investigations data for added non-overlapping periods.
FTC merger investigations data are reported in cumulative periods, e.g., 1996-2003 and 1996-2011, but the analyst may want data reported in non-overlapping periods, e.g., 2004-2011. Given the way in which FTC had reported merger investigations data, the above example is the only instance in which the 1996-2003 data can be subtracted from the cumulative data to extract merger investigations data for the later period. See also, Kwoka, Sec. 2.3.3. [1]
- Parameters:¶
- _archive_path : pathlib.Path¶
Path to file container for serialized constructed data
- flag_backward_compatibility : bool¶
Flag whether the reported data should be treated as backward-compatible
- flag_pharma_for_exclusion : bool¶
Flag whether data for Pharmaceuticals is included in, the set of industry groups with consistent reporting in both early and late periods
- Returns:¶
A dictionary of merger investigations data keyed to reporting periods
- Return type:¶
mergeron.core.INVData
