Any government intervention, program or policy implementation may have its impact on economic development. Academia and civil society started a global movement to put value into ensuring that different policies are designed and implemented with the most efficient use of allocated resources. Impact evaluation (IE), particularly the Randomized Controlled Trials (RCT), became the strongest tool in revealing evidence on causal inference and finding out whether targeted outcomes are direct effects of program intervention or stem from other processes. This helps answer questions on effectiveness of a program, decision to scale it up, postpone or close.
