1. Manos Matsaganis & Panos TsakloglouAthens University of EconomicsFBBVA Microsimulation WorkshopMadrid 15-16 November 2004 Microsimulation and the analysis of poverty and inequality an illustration

2. Microsimulation, poverty and inequality (1) • MS can help analyse the effect of policy changes • examine redistributive impact of current policies • explore impact of reforms vs. some baseline • answer counterfactual («what if»-type) questions

3. Microsimulation, poverty and inequality (2) • MS can help produce various types of output • analyse the impact of policy changes in terms of: • changes in the income distribution • poverty and inequality • distribution of gains and losses • i.e. winners and losers in the entire population ... • ... or by population group (lone parents, elderly etc.) • fiscal implications of policy changes • excl. administrative costs

4. Microsimulation, poverty and inequality (3) • MS can help calculate RRs and METRs • replacement rates • does work pay? • marginal effective tax rates • poverty trap? • unemployment trap?

5. Microsimulation, poverty and inequality (4) • MS can help disentangle separate effects • taxes and benefits interact • e.g. raising benefit rates will raise pre-tax incomes, so it may move recipients to a higher tax band ... • ... while lowering taxes will raise pre-tax incomes, so it may cause recipients of income-tested benefits to lose eligibility • no other way to account (separately and jointly) for the effect of taxes and benefits on final disposable incomes

8. The paper • aims to assess the impact • of family transfers • on child poverty • in southern Europe • Greece • Italy • Spain • Portugal • using microsimulation • the tax-benefit model EUROMOD

9. Family transfers • definition • all income transfers to families with children • child benefits (non-contributory) • family allowances (contributory) • tax relief for dependent children • non-cash benefits (e.g. child care) not included

10. Child poverty • issue has risen to prominence • poor children by definition “deserving” • social costs of child poverty vs. benefits of early intervention • anti-poverty measures  human capital investments • high future returns! • political commitments • Blair pledge to eliminate child poverty in Britain by 2020 • Commission proposal to halve child poverty in the EU by 2010 (not endorsed by the Council)

11. Southern Europe • tradition of “familialism” • strength of informal safety nets • but are family resources adequate for intra-family redistribution? • subsidiary role of formal safety nets • public assistance to families meagre / not available at all • reliance of tax benefits  what about those too poor to pay tax? • uneven coverage gaps in protection

13. EUROMOD (1) • what is it? • a tax-benefit model for all 15 “old” EU members • construction funded by EC TSER / FP5 programmes • 40 persons in 18 centres led by Cambridge University • main objective: comparability • what can it do? • analyse policy changes in a comparative setting • examine impact of current policies • explore impact of reforms • answer “what if?”-type questions

14. EUROMOD (2) • what data does it rely upon? • EC Household Panel (Greece / Spain / Portugal) • Bank of Italy Survey of Household Income & Wealth • updated to 1998 • 2001 dataset in progress • what sort of policies does it simulate? • income taxes, social contributions • social assistance, housing, family, unemployment and some social insurance benefits, e.g. social pensions • 1998 & 2001 rules applied • 2003 update in progress

15. EUROMOD (3) • what types of output does it produce? • estimates of policy impact in terms of: • income distribution • fiscal costs • distribution of gains and losses (winners and losers) • calculations of: • marginal effective tax rates • replacement rates

16. EUROMOD (4) • temporary difficulties? • no simulation of benefits in kind(publicly provided services) • full tax compliance (no tax evasion) • no targeting errors (100% take up / no leakage) • given sufficient effort (and funding), all of the above may be fully or partly amenable to treatment

17. EUROMOD (5) • structural weaknesses? • static microsimulation • no behavioural responses • e.g. labour supply • consumer demand etc. • nonetheless: • dynamic models sensitive to assumptions • in the short term, static MS may be sufficient

31. Reforms (1) • reforming family transfers • abolish all current policies • introduce universal child benefits • what if ...?

32. Reforms (2) • why universal child benefits? • obvious solution to the problem of gaps in coverage • ... though controversial • good for illustration • easy to explain • simple to implement

33. Reforms (3) • which universal child benefits? • various issues involved • benefit level • variation by age • variation by no. of children etc. • 5 variations of UCB reform 2 “artificial” universal child benefits • poverty-neutral / budget-neutral 3 “actually existing” universal child benefits • British / Danish / Swedish schemes ... ... adjusted in terms of average male f-t earnings

40. 1. Introduction • 2. Data and methodology • 3. Incidence of child poverty by household type • 4. Distributional impact of family transfers • 5. Simulating reforms • 6. Discussion and policy implications

41. Concluding remarks (1) • performance of family transfers modest • many poor families are ineligible for assistance (GR / IT) • ... or receive low benefits (SP / PT) • non-refundable tax credits exclude poor families by design

42. Concluding remarks (2) • performance of UCBs disappointing? • replacing current policies by UCBs would not reduce the number of poor children by much – and could even increase it! • impact of UCBs weak or negative where current policies provide substantial benefits to a considerable subset of the low-income population (as in Italy)

43. Concluding remarks (3) • headcount poverty too severe a test for UCBs • where existing policies leave coverage gaps, those currently ineligible for assistance will be better off under a UCB even when they remain below the poverty line • headcount poverty rates cannot capture such improvements • bringing in the FGT index (implying more concern for those at the bottom of the income distribution) does more justice to the anti-poverty impact of UCBs

44. Concluding remarks (4) • not all UCBs are the same • the Danish UCB, paying higher amounts to younger children, emerges ahead of the others in terms of generosity and anti-poverty effectiveness • The British and the Swedish UCBs, though different in structure (the former paying a higher rate to the eldest child, the latter rising in value with family size) have similar effects on child poverty and fiscal costs

45. Concluding remarks (5) • playing field uneven • 100% take up a reasonable assumption for universal benefits – not so for currrent income-tested policies • in favour of universal child benefits • low administrative costs • no stigma • no adverse labour incentives (i.e. no poverty traps)

46. Concluding remarks (6) • the case for UCB wider • horizontal redistribution • from single tax payers to families with children • children a (partly) public good • social citizenship • access to certain benefits can be a citizen right • political economy considerations • narrowly targeted programmes at risk of backlash • support for universal programmes broader-based

47. Concluding remarks (7) • a basic trade off at work • more generous UCBs are more effective but costlier • but: current spending on family transfers far too low • hard to reduce poverty via internal reallocations alone

48. Concluding remarks (8) • way forward? • judiciously combine a universal (even if low) income base ... • to address the problem of gaps in coverage • to achieve horizontal redistribution ... with more targeted (non-categorical) interventions • to direct extra resources to families in need • to improve effectiveness of both type I and II

49. Concluding remarks (9) • bring in services ... • there is more to fighting child poverty than cash benefits alone • universal access to affordable, good-quality family services a high priority • a child care guarantee a promising route out of poverty

50. Concluding remarks (10) • ... but avoid the other extreme • services a complement of cash benefits, not a substitute • proper design of income transfers still relevant!
