I found the answer, eventually - though it was not a term I was familiar with

***Market income*** - Plain language definition:

Total income before tax minus income from government sources.

Detailed definition:

Refers to the sum of employment income (wages and salaries, net farm income and net income from non-farm unincorporated business and/or professional practice), investment income, retirement pensions, superannuation and annuities (including those from RRSPs and RRIFs) and other money income. It is equivalent to total income before tax minus all government transfers and is also referred to as income before transfers and taxes.

I had thought the income described here is gross income. But I had never heard it referred to as "renda del mercat" before. See my other note above for the right answer.
