A balance‐sheet approach to fiscal sustainability

Abstract

AbstractThis paper proposes an alternative methodology to assess fiscal sustainability. Our balance‐sheet approach (BSA) relies on estimating separately all of a government's assets and liabilities as opposed to focusing only on the burden of explicit liabilities. In our approach, assets are primarily the present discounted value of taxes, and liabilities include explicit liabilities but also the present discounted value of expenditures. Using the value of assets and liabilities, we compute the government's balance sheet, and therefore net worth. We then evaluate the response of net worth to growth, commodity prices or real exchange rate shocks. By computing a value for the government's net worth, our methodology allows an assessment of fiscal sustainability that is less reliant on the analyst's assumptions than traditional debt sustainability analysis (DSA).
