The determinants of fiscal deficits: a survey of literature
Persistent deficits are fast leading to an
accumulation of government debt across the world. In our latest paper, we surveyed the
existing literature, both theoretical and empirical, on the determinants of
fiscal deficits. The theoretical literature highlights the role of the Ricardian
equivalence theory, the Keynesian theory, the neoclassical theory, and political
budget cycle hypothesis in shaping the current discourse on budget deficits and
their effects on other variables. A review of the empirical studies reveals
that: economic growth, debt, unemployment rates, trade openness, level of
development (GDP per capita), level of urbanization, extreme weather events,
current account balances, inflation, aid, military spending, as well as
political factors, and quality of budgetary institutions are important
determinants of budget deficits. While research on the linkage between the
structure of the economy and persistence of the budget deficit is limited,
evidence shows that tax base variability is associated with procyclical fiscal
policy. Beyond these findings, the determinants of fiscal deficits are country-specific.
