This chapter captures some of the PublicInvestment Management (PIM) lessons and experiences fromTimor-Leste as it tried to meet urgent infrastructuredemands in a post-conflict environment, which benefited froma surge in petroleum receipts. It looks at institutionalchanges using standard features of Public InvestmentManagement systems starting from the immediatepost-independence period in 1999 right up to the launch ofTimor-Leste s Strategic Development Plan in July 2011.Increased control over domestic resources over this period,thanks to the onset of natural resource rents, gave thegovernment more autonomy over prioritization and managementof capital expenditure. It also enabled use of the CapitalBudget to pursue multiple objectives including consolidatingsocial stability, stimulating economic activity outsideDili, delivering quick results to address urgentinfrastructure needs, and growth of the domestic privatesector. The chapter tries to highlight some of thetrade-offs that the PIM system faced in trying to meet thesedifferent objectives. It finally looks at some of theinstitutional reforms that the government embarked on in2011 when the focus was shifting to large investments forlong-term growth. This included centralizing selected PIMfunctions for large projects and decentralizing thosefunctions for smaller projects.
