NEEDS SUBMITTED BY RESPECTIVE EAC CENTRAL BANKS
  • The below proposed training modules in Modelling
    and Forecasting is a compilation of Needs
    submitted by the five EAC Central Banks,
  • These modules are proposed to be used during the
    short training programme of staff from EAC
    Central Banks as recommended by the last MAC
    meeting held in Kigali on May 2009.

1. Banque de la republique du Burundi (BRB)
  • Due to lack of enough qualified staff in
    econometric analysis, BRB has suggested to
    organize training in two phases enrichment of
    the training and capacity building.
  • Enrichment of the training should focus on
    overview of the theory related to economic and
    statistic analysis. This would be concentrated
    on Inflation forecasting, Monetary aggregates,
    exchange rate and banking liquidity.

1. Banque de la republique du Burundi (Contd)
  • For capacity building, BRB would suggest to
    organize an internal training before the joint
    training within EAC. This would facilitate
    Burundis team to be on same page with their
    colleagues of the EAC Central Banks. To this end,
    some topics have been identified for the internal
    training
  • Introduction to statistical analysis
  • Single and multiple regression models
  • Introduction to stationarity, unit roots and
    cointegration

    needs in training with detailed topics and their
    justification
  • Basic Econometrics linear regression analysis,
    system of equations,
  • Time series econometrics stationarity/unit
    roots analysis, testing unit roots,

Conclusion
  • The reality found in EAC Central Banks confirms
    that the training in Modelling and Forecasting is
    for great necessity .
  • The heads of research department in respective
    EAC Central banks are welcoming the initiative
    proposed by UNECA of providing such kind of
    training and manifested interest to attend and to
    benefit from this training in order to improve
    the used methodology in terms of modelling and
    forecasting in macroeconomic and financial
    analysis

27
Conclusion (Contd)
  • As the EAC is deepening and widening its regional
    integration, the harmonisation of macroeconomic
    and financial analysis will facilitate to
    eliminate gaps observed in interpretation of
    national and regional economy
  • Each central bank provided its priorities in
    terms of training based on its own realities.
    Because of diversification in terms of needs, it
    was not easy to consider all needs provided by
    every individual Bank. To this end, a common
    training module has been formulated based on
    general and common needs. However, the specific
    needs may be considered in an individual local
    training which may be organized exclusively for
    the concerned Central Bank

28
Recommendations
  • Besides the common training formulated in the
    present report, BRB needs a particular training
    as summarized in their needs. Due to lack of high
    qualified staff in macroeconometrics, the
    specific training would start from
    introduction to statistic analysis and
    introduction to the use of software applied in
    econometric analysis. The training would be
    provided by a local expert in order to avoid high
    costs of an expatriate.
  • The common training would be more focusing rather
    than theoretical. The case study of each
    participating country would provide a good
    example of practice of the theory.

29
Recommendations (Contd)
  • As the Modelling and Forecasting Program is not a
    particularity of Central Banks alone, it is
    recommended to involve other staff from other
    institutions concerned by the topics (e.g.
    Ministries of Finance, Institutes of Statistics,
    etc.)
  • Due to the importance and the complexity of the
    training in Modelling and Forecasting, this kind
    of training should be organized periodically in
    order to make sure that the previous training has
    produced positive results.
