+ "on whether it implements the right policies now while the economy continues to recover.\n\n"
+ " First, with public debt above 100 percent of GDP and only starting to come down, Belgium still\n"
+ " has a long way to go to rebuild buffers and achieve a more sustainable fiscal position. This will\n"
+ " require following through on plans to gradually move toward structural balance.\n\n"
+ " Second, with real GDP growth projected at only around 1½ percent for the foreseeable future,\n"
+ " further labor and product market reforms are needed to increase productivity growth, raise\n"
+ " potential output, and integrate vulnerable groups into the labor market.\n\n"
+ " Third, although the financial sector has recovered since the crisis and is generally sound, cyclical\n"
+ " vulnerabilities are rising and new challenges are emerging, suggesting the need for vigilance\n"
+ " and proactive policies.3\n\n"
+ "8. The government agreed last summer on a new package of measures related to\n"
+ "taxation, the labor market, and social benefits (Table 2 and Box 1). The most notable reform was\n"
+ "a reduction in Belgium's corporate income tax (CIT) rate from 34 percent to 25 percent, to be\n"
+ "phased in over the next three years (SMEs will benefit from a reduced rate of 20 percent starting in\n"
+ "2018). To compensate for the resulting revenue loss, the notional interest rate deduction (NID) was\n"
+ "modified to apply only to incremental corporate equity rather than to the total stock, and new anti-\n"
+ "tax avoidance measures were introduced consistent with Belgium's EU obligations.4 Together, the\n"
+ "measures are designed to enhance Belgium's competitiveness while preserving revenue neutrality.\n\n"
+ "9. Policy discussions focused on the importance of maintaining the reform momentum\n"
+ "and not yielding to complacency. Achieving the balanced budget goal will require efforts at all\n"
+ "levels of government to make spending more efficient and safeguard revenues (Section A).\n"
+ "A combination of policies and reforms could help raise productivity growth, including increasing\n"
+ "investment in infrastructure and enhancing competition in services (Section B). To fully realize\n"
+ "Belgium's employment potential, it will be critical to address the severe fragmentation of the labor\n"
