This Public Expenditure Review is focused on the quality and sustainability of public spending. The key objective of this Public Expenditure Review (PER) is to assess the quality of public spending, by evaluating its efficiency and effectiveness, while also delving into sustainability considerations, by gauging domestic revenue mobilization and the fiscal implications of current spending levels. This work aims to strengthen the evidence base for decision-making on public expenditure and revenue management. Its scope does not include a strong focus on equity, owing to the lack of a recent household survey, the last survey of livings standards was conducted in 2014. Nonetheless, equity dimensions are considered whenever possible and relevant evidence is mentioned. Overall, the analysis underscores the need for prioritizing and improving the quality of public investments, rationalizing undue recurrent spending and enhancing revenue collection.
