  1. Forecasting, analysis and policy process in inflation targeting Jaromír Hurník (jaromir.hurnik@cnb.cz) Monetary policy division Czech National Bank

  2. Outline 1. Forecast objective 2. Current practices 3. Elements of the process 4. Summary and challenges

  3. 1. Objective of the Forecast - I • IT implies a medium-term approach • necessary to have consistent and clear methods to derive a forecast for inflation • important also externally - want forward looking agents to form expectations according to systematic reactions of CB (show you are systematic!)

  4. 1. Objective of the Forecast - II • Present a consistent view of • where the economy is, and what the current trends are • what are their likely evolution into the future • what are the implicit risks • what are the underlying pressures in terms of policy

  5. 1. Objective of the Forecast - IV • Transparency requires broad involvement of all the staff with clearly defined roles in the process • Efficiency requires use of a common language among the staff • role of a core model • and open architecture • flexibility to incorporate various views and alternatives

  6. 2. Current practices: history and overview - II • Development - NT forecasting • NT forecasting - “expert approaches” at first • NT forecasting - more data-based approaches • single-equation • some simultaneous systems • policy horizon (4-6Q) covered • no active MP • detailed sectoral forecasts

  7. 2. Current practices: history and overview - III • Development - MT forecasting • striving for “the best model” for a couple of yrs • introduction of simple gap model (2000/2001) • calibrated • forward looking • active MP • policy experiments possible and appreciated by the board • lot of work on internal forecasting process

  8. 2. Current practices: history and overview - IV • Current state: • one forecast - combines advantages of both approaches • intra-departmental forecasting team • board meets monthly • Q projection exercise + “dark times” w/o forecast • “situation reports” (30-60p.) monthly + “inflation reports” quarterly

  9. 2. Current practices - V • Monetary Policy • 2 policy analysis experts • ** organisation, documentation Head of the Department • External developments • ext. Assumptions (CF) • ER - order flows Forecasting Team • Real Economy • GDP specialist • Inflation specialist • ** NT forecast • Economic Modelling • Model operator • Model Database • ** MT forecast • Monetary Analysis • fiscal sector specialist

  10. 2. Current practices - VI • Forecasting team • 10-15 economists • all divisions represented (head + 1-2 economists) • experts may get invited to topics • open entry: department, advisors, board members • head of team: head of department + co-ordinator

  11. Post morterm Equilibria and initial conditions - with BB Fcasting techniques GDP data Inflation data 1st round of NTF Alternatives with BB WEEKS 1 2 3 4 5 0 BB meeting on Monetary Policy Equilibria and initial conditions 1st Issues meeting 2nd Issues meeting Fcast rounds 3. Elements of the Process - I

  12. 3. Elements of the Process - II • Meetings on Forecasting Techniques • properties of main forecasting tools are re-introduced • opportunity to introduce changes and their significance • refreshes staff's and FT's familiarity with the techniques and their pitfalls

  13. 3. Elements of the Process - III • Issue Meetings • collective and intuitive view among the staff where the economy is and what are the current economic issues • designed to address a wide range of questions • recent data out-turns • analytically sophisticated issues • broad participation of staff encouraged

  14. 3. Elements of the Process - IV • Meeting on Near Term Forecast • is more about where the economy is and what the current shocks are • essential input for Medium Term (model) Forecast • integral part of the overall message

  15. 3. Elements of the Process - V • Meeting on Equilibrium and Initial conditions • gap model • have the equilibrium trends changed (not often) ? • where are we now ? - Kalman filtering + expert knowledge • + external assumptions (Consensus forecast) • exchange rate - mix of model consistent UIP and order flow forecasts (BoP)

  16. 3. Elements of the Process - VI • Forecast Rounds of Medium Term Forecast • is more about where the economy is going to go beyond the NTF • make the core model behaviour consistent with the views of experts and other model tools • work incrementally to alter the baseline scenario • if consensus emerges, prepare alternatives • use the model mechanisms to interpret the forecast

  17. 3. Elements of the Process - VII • Meetings with the BB • staff's forecast but active involvement necessary • build credibility, feeling of openness • two meetings prior to official BB meeting: • equilibrium and initial conditions (+ formal approval of external assumptions) • alternatives - which risks it is worth to elaborate

  18. 3. Elements of the Process - VIII • Post Morterm Meeting • opportunity to systematically asses what went to wrong and what should be strengthened • broad participation encouraged • effective tool to transform fresh emotions into effective measures for the next time

  19. 3. Elements of the Process - Documentation

  20. 4. Summary and challenges -I • Shift from data collection to information extraction • More structured debate about risks and policy issues + common language • “what if…?” questions can be answered • Forecast with active monetary policy (includes rates trajectory consistent w/ fcast)

  21. 4. Summary and challenges - II • no pure model forecast => consistency check role is partially an illusion • more dis-aggregated discussion within the same framework may be difficult => new model? • writing reports vs. doing analysis - situation vs. inflation report • decision making system in between Q projection rounds (RBNZ scatter plot ?) • interaction with the bank board
