When you join the World Bank Group, you become part of a dynamic, diverse organization with 189 member countries and more than 120 offices worldwide. We work with public and private sector partners, invest in groundbreaking projects, and use data, research, and technology to bring tangible and transformative changes around the globe.

VPU Context: The Development Economics Vice Presidency (DEC) is the World Bank's central reservoir of fresh insights into the most pressing challenges of development. It is led by the Chief Economist and Senior Vice President of the World Bank Group, who advises the President and senior managers, serves as the community leader for the WBG's economists, and helps to keep the institution in the forefront of thinking about development policy. DEC constitutes one of the world's largest teams of economists focused on policy solutions for developing economies.
Unit Context: A department of the World Bank's Development Economics Vice-Presidency, the Development Impact Department (DECDI)I's purpose is to increase the use of impact evaluation (IE) in the design and implementation of public policy and to develop institutional capacity and motivation for evidence-based policy. DECDI's work focuses on:

Evaluating programs at scale to answer policy-relevant questions.
Developing innovative data systems and data analytics tools for real-time decisions.
Using causal inference analysis to identify mechanisms to improve results.
Building capacity to strengthen country institutions for evidence-based policymaking.

DECDI aims to overcome the challenge to identify true cause-and-effect relations in policy programs. By linking researchers to policymakers and feeding results back into policies, DECDI fosters systematic use of evidence, which informs adoption, mid-course corrections, and scale-up of policies. Through workshops and clinics with operational staff and government clients, joint research teams, active field coordination, as well as research products such as seminars, papers, and policy briefs, DECDI builds capacity while forming a wider community of practice.

DECDI accompanies impact evaluations during their entire life-cycle. It starts with assessing demand, identifying research questions, as well as supporting project implementation, high quality data collection, analysis, and dissemination of results.

With a portfolio of more than 220 impact evaluations, DECDI operates across all sectors in about 60 countries spanning the globe. The IEs test a variety of interventions and mechanisms to understand why policy succeeds or fails and how to improve policy design and implementation to obtain better results. By working proactively in collaboration with clients, DECDI employs experimental methods to infer causality whenever possible (79% of the portfolio). 17% of DECDI IEs utilize non-experimental methods, while 4% use a combination of the two. DECDI is structured into 5 World Bank units:
DECPL: Planet Impact Lab.
DECPE: People Impact Lab.
DECPR: Prosperity Impact Lab.
DECID: Infrastructure and Digital Impact Lab.
DECMB: Behavior Science Lab.
