Abstract
Amid rising public debt, persistent inflation, and expanding public expenditure, many governments are turning once again to tax reforms to strengthen their fiscal positions while maintaining fairness and efficiency. But designing effective tax reforms is no simple task. Policymakers must find ways to raise sufficient revenue without undermining work incentives, distorting investment, or worsening inequality. In this context, a familiar concept in public finance — the Laffer curve — offers insights into the limits and possibilities of tax policy.
