National accounting with natural and other types of capital

We do double-entry national accounting and incorporate zero profit arbitrag e conditions (Euler equations) for different types of capital, including na tural capital. In non-balanced growth, capital gains terms for capital good s appear in the income side of the accounts. Depreciation terms appear on t he product or expenditure side. We consider renewable natural capital as we ll as non-renewable of both durable and non-durable types.
