4. 1. Overview of the results • During the implementation phase 2007-15 (nine years instead of the formal seven year SF interventions) two separate mechanisms work: • The demand side effect (mainly through programmes of public and accompanying private investment) • The supply-side effect which work through the build-up of stocks of infrastructure, human capital and R&D. • After the termination of the programmes in 2015 the demand side effects will vanish rapidly but the supply-side effects will remain for a longer period.

5. 1. Overview of the results, continued • When measuring the impact of the NSRF it is important to distinguish between • Level effect • Growth effect • The Level-effect compares the economic outcome relative to a baseline-scenario and can be expressed as a percentage or absolute difference from the baseline. • The Growth-effect compares the different growth rates within one scenario with the growth rates in a baseline scenario. • Even if there are large level effects the growth rates can be very similar.

7. 1. Overview of the results, continued Revised expenditure profile of the NSRF (euro million per year) And as % of the NSRF per year

8. 1. Overviewof the results, continued Effects of the NSPF on the real Czech GDP Level effect compared to the baselineas %-difference Growth rates effect, as % difference Gradually increasing impact on the level of GDP compared to the baseline-scenario (without NSRF), even in 2020 the level about 2% percent higher then without the NSPR Moderate differences up to one percent during the implementation phase and a significant difference in 2016

9. 1. Overview of the results, continued • In 2007 the initial effect on employment compared to the no-NSRF baseline is just over 20 thousand, given the initial low injection by the SF • In 2013 this has built up to 196.000 and is still 178.000 in 2015. • In 2020 total employment is still 29.000 higher. • The NSRF introduces extra productivity gains of around 1% over the baseline. This is notable since even in the baseline there is are substantial increases in productivity.

10. 2. Modelling the Czech Economy • Very limited modeling research of the Czech economy • Only recently policy-making institutions (MoF or the Central Bank) set-up a structural approach to economic modeling • Not all material is in the public domain! • Lack of long data series is a serious problem • Models developed have a main focus on: • Monetary and fiscal policy issues and • Long-term growth, structural change and convergence prospects.

11. 3. The HERMIN Modelling ApproachA pictorial outline of the model

12. Important economic relationships • Output: Exposed and sheltered sectors • Production inputs: Labour and capital • Output prices: Price taking and price making • Wage determination: Bargaining and sectoral transmission • Labour supply: natural growth, migration, participation • Consumption: Is there a liquidity constraint? • Trade: Modelled as a net trade balance (exports minus imports) • Government: General government expenditure, revenue and balance

13. What determines sectoral output? • Manufacturing: Local & external demand; competitiveness • Market services: Local demand • Agriculture: Productivity • Government: Public employment

14. What determines production inputs? • Output • Cost of labour compared to cost of capital • Technical progress

15. What determines output prices? • Manufacturing: World prices, labour costs • Market services: Labour costs • Building and construction: Labour costs • Agriculture: Common Agricultural Policy (CAP)

16. What determines wage rates? • Consumer prices • Output prices • Productivity • Unemployment rate

17. What determines labour supply? • Population growth, but more specifically • Working age population growth • Participation rate • Net migration flows

18. What determines household consumption? • Income, but more specifically • Household income, but more specifically • Household disposable income • Wealth??

19. What determines trade? • National data on exports and imports are available • Net regional trade balance (NTS) determined as production (GDPM) less regional absorption (GDA) NTS = GDPM - GDA

20. What determines general government revenue and expenditure? • Revenue: Tax bases and tax rates • Expenditure: Policy decisions (discretionary) as well as policy rules (automatic)

21. Model calibration • “Old” EU models: Simple econometrics (OLS), using data for period 1980-2004 • Czech national model: Curve-fitting and selective parameter imposition, using data for period 1995-2004 • Other approaches to calibration: (i) Extend data sample, using pre-1995 (or even pre-1989) data? (ii) Panel data from group of countries (imposing cross-country constraints)

22. HERMIN documentation • Data-based description of the economy • Theoretical underpinnings of the HERMIN modelling framework • Calibration of the behavioural equations • Model testing: simulations and shocks • Data appendix, model listing: public domain • Standardised software:

23. Uses of a HERMIN-type model • Preparation of economic forecasts • General economic policy analysis • NSRF-related policy analysis • Design/evaluation of national industrial strategies

24. Preparation of economic forecasts • Short-term national forecasts (12 months) are widely available • Medium-term national forecasts (up to 5 years) are very rare • Long-term economic forecasts of any kind are not usually available

28. 5. The NSRF Evaluation How to analyse the SF interventions

29. Construction phase vs Use phasefor cohesion policy • During construction phase, there will be large demand-side impacts. These vanish after completion (i.e., after 2013 for next NSRF) • Increased stocks of infrastructure, human capital and R&D can generate long-tailed supply-side impacts • The size of the supply-side impacts depend on the appropriateness and effectiveness of the NDP

30. Inserting a CSF/NDP into HERMIN • The three aggregate elements of a CSF (a) Physical infrastructure (b) Human resources (c) Direct aid to productive sector • Conventional Keynesian expenditure and income impacts (role of policy multiplier) • Additional externality effects onoutput and productivity

31. ImplementationversusUse phasein evaluation • During the implementation phase, there will be large demand-side impacts. These vanish after completion (i.e., after 2013/15 for next NSRF) • Increased stocks of infrastructure, human capital and R&D can generate long-tailed supply-side impacts • The size of the supply-side impacts depend on the appropriateness and effectiveness of the NSRF

32. Physical infrastructure: PI • Demand-side impacts (implementation): PI  IG  I (total investment)  (Keynesian multiplier)  impact on GDP • Supply-side impacts (mainly post-implementation): PI  increased stock of infrastructure (KPI)  boost to output/productivity

33. Human resources: HC • Demand-side impacts (implementation): HC  Income & Public expenditure  Keynesian multiplier  GDP • Supply-side impacts (mainly post-implementation): HC  stock of human capital (KHC)  boost to output/productivity

34. Research and Development • Demand-side impacts (implementation): R&D  I (total investment)  (Keynesian multiplier)  impact on GDP • Supply-side impacts (mainly post-implementation): R&D  increased stock of R&D (KRD)  boost to output/productivity

35. A serious methodological challenge • Ex-ante impact analysis of “yet-to-be-implemented” NDPs • Is the NSRF appropriate? How effective will be the implementation? • Strict monitoring and evaluation can help, but do not guarantee success

36. Infrastructure, human capital and R&D: interaction effects • The links between infrastructure, human capital and R&D are difficult to measure. • A parallel improvement in all three is probably necessary • But we cannot say much about the optimum balance between them within an NSRF

37. Where do the spillover measures come from? • International literature on the impact of PI and HC on output and productivity • Comprehensive ESRI survey • Recent survey of HC impacts by IFS • Problems: very little from cohesion countries! nothing from CEE countries no agreement on size of impacts! no agreement on level versus growth impacts!

38. Presenting model-based cohesion policy impacts • Difficult to define an appropriate counterfactual baseline scenario. • Difficult to assign values to the spill-over (or externality) elasticities to different countries in he absence of empirical research. • Macro impacts are complex, and GDP is an imperfect indicator

39. 5. The NSRF Evaluation

49. 6. The future of the Czech NSRF Evaluation Summing up: • the NSRF interventions will have a large impact on the level of GDP during the implementation phase up to 4.5% of GDP until 2015 compared to a baseline scenario and • in the long-run the level of GDP will be around 1.5% higher • there will be extra productivity gains and • employment will be higher then in the non-NSRF scenario. Altogether the SF interventions will have a positive impact on convergence, the size of which will depend on the quality on the interventions.

50. 6. The future of the Czech NSRF Evaluation • These outcomes are based on a set of specific assumptions • Specific externalities for infrastructure, R&D and human capital • These externalities are high when the quality of the interventions are high • The likely impact of other issues like the Single Market, enhanced FDI etc. are not explicitly modeled. • These linked to the Structural Funds will further enhance convergence.
