مالیات بر درآمد با بودجه پایدار و ثبات کلی در یک بازرگانی کوچک؟ یک اقتصاد

In a closed economy, a balanced-budget fiscal policy rule with endogenous income tax rates can generate aggregate instability due to self-fulfilling expectations (e.g., Schmitt-Grohé and Uribe, 1997). This paper shows, both analytically and numerically, that beliefs-driven aggregate instability associated with such a balanced-budget rule is less of a problem in a small open economy integrated in the world asset and goods markets. This is because cross-border capital flows and endogenous international price adjustments produce income effects that reduce the likelihood of sunspot equilibria. From a policy perspective, our results relieve possible concerns that balanced-budget rules and reliance on income taxes to achieve budget objective could have destabilizing effects on the economy.
