Jaime Biderman was born in 1949. He joined the World Bank in 1973 as a researcher in the Economic Department's Urban and Regional Economics Division (ECDRB). The following year Biderman entered the Bank's Young Professionals Program (YPP). Upon his completion of the Program in 1976, Biderman was made an Economist in the Transportation and Urban Projects Department's Urban Division (TRUD2). Shortly thereafter the two sectors, Transport and Urban Development, were separated and Biderman was placed in the newUrban Projects Department (URB). Note that while following the 1972 Bank-wide reorganization most sector departments were only responsible for policy formulation and quality control, URB functioned as a centralized operating projects department, meaning that it provided a full operational package of technical services to the regional operational vice presidencies. This included the planning, direction, and supervision of project work.

Biderman took an extended leave from the World Bank from 1978 to 1983.Upon his return he continued his work as an Economist in the Urban Development sector. Regionalization of URB and project planning and supervision functions had, however, begun in 1979. Thus when Biderman joined the East Asia and Pacific Regional Vice Presidency's Urban and Water Supply Division (AEPUW) in 1983, its functions included the full operational package of responsibilities within the East Asia and Pacific Regional Vice Presidency (AENVP). Biderman remained in the AEPUW through 1987.

In 1987 Biderman moved to the Africa Vice Presidency's Department 6 (AF6) responsible for overseeing lending operations in Botswana, Lesotho, Malawi, Mozambique, Swaziland, Tanzania, Zambia, and Zimbabwe. Biderman worked as a Senior Economist in the Department's Country Operations Division (AF6CO).

In 1991, following a brief period in the Development Economic's Policy and Review Department (PRD), Biderman was named Senior Country Officer in the Europe and Central Asia Vice Presidency (ECA).

In 1994 Biderman was named Operations Adviser in the Operations Policy Department (OPR). OPR was responsible for operational policy development, portfolio management monitoring and evaluation, and procurement guidance and policy, among other activities. Biderman worked in the Department's Policy Group (OPRPG).

In 1998 Biderman returned to the Africa Vice Presidency (AFR) and would remain there until 2009. During this period Biderman held a variety of positions in a number of AFR's divisions. These included:

• Lead Specialist,Operations Support 1 (AFTS1, 1998-1999)

• Lead Specialist, Operational Quality and Knowledge (AFTQK, 1999-2000)

• Sector Manager, Water and Urban 1 (AFTU1, 2002-2008)

• Sector Manager, Urban and Water (AFTUW, 2009)

Biderman served as an Adviser in 2010 and 2011 in an unspecified role before retiring from the Bank in 2011. In [year], he returned as a consultant for a variety of Bank units, including the Independent Evaluation Group (IEG).
