Splitting Corporations by industry #107

Open codykallen opened 4 years ago

codykallen commented 4 years ago

Forthcoming work will split the single Corporation into different Corporations for each industrial sector (with some subsectors). We will thus have a Corporation for each of the following, along with identifying codes:

                  'FARM': 'Farm',
                  'FFRA': 'Forestry, fishing, and related activities',
                  'MINE': 'Mining',
                  'UTIL': 'Utilities',
                  'CNST': 'Construction',
                  'DMAN': 'Durable goods manufacturing',
                  'NMAN': 'Nondurable goods manufacturing',
                  'WHTR': 'Wholesale trade',
                  'RETR': 'Retail trade',
                  'TRAN': 'Transportation',
                  'INFO': 'Information',
                  'FINC': 'Credit intermediation (Finance)',
                  'FINS': 'Securities, commodity contracts, and investments (Finance)',
                  'INSU': 'Insurance',
                  'REAL': 'Real estate',
                  'LEAS': 'Rental and leasing',
                  'PROF': 'Professional, scientific, and technical services',
                  'MGMT': 'Management of companies',
                  'ADMN': 'Administrative and waste management services',
                  'EDUC': 'Educational services',
                  'HLTH': 'Health care and social assistance',
                  'ARTS': 'Arts, entertainment, and recreation',
                  'ACCM': 'Accommodation and food services',
                  'OTHS': 'Other services, except government'

This will require adjusting the Corporation class to accept industry codes and use different results for each industry. It will also require adjusting the net interest deduction model to handle different industries, including different adjustment factors, to be applied to the original data as is now the case for the capital and investment data.

It will also require adjusting the AMT parameters to apply separately for each industry; it may be advisable to reuse some of the parameters across industries. The same need will apply when calculating the FTC parameters, although the FTC model could also use some revision.

This will also require work on the CFC and DomesticMNE classes.
