9 Inequality promotes risks Social and economic inequalities can tear the social fabric, undermine social cohesion and prevent nations from thriving Societies where opportunities are scarce are vulnerable to upheaval and conflict Can jeopardize the well-being of large segments of the population through low earnings/wages, and leads to decrease in healthy life and development Vulnerable populations have lower levels of education, lack skills and abilities that can allow them to compete in labour market Structural barrier constraining domestic markets Can breed crime, disease and environmental degradation and hamper economic growth and thereby poverty reduction Inequality of opportunities impede development of capabilities If inequalities continue to widen, development may not be sustainable 9

10 Policies to promote equity A suggested framework Forward-looking macroeconomic policies Institutional and governance policies Social welfare programmes -Provisioning of quality basic public services -Investing in people, their growth and capabilities -Employment generation, sufficient, productive and decent -Financial Market Policies -Trade Polices -Institution Building Polices -Promoting women s empowerment -Strengthening regulations and judiciary -Reforming public finance system including income tax base/ tax administrations & corporate tax -Welfare enhancing programmes for education, health, food, housing and social security/legislations -Employment guarantee programmes -Minimum wages -Land reforms - 10

11 Types of Inequality Social and economic inequalities Social: Education & health services, wages and land assets Income: GDP per capita, or household income/expenditure Spatial inequalities Inequalities between regions, subregions and countries Inequalities within countries at subnational level Rural and urban areas Horizontal inequalities Social groups such as youth, older persons, indigenous persons, Also, minorities, persons with disabilities and migrants workers 11

14 Methodology Gini coefficient of inequality Generalized entropy class (GE) to allow inequality across groups to be broken down into within group inequality and between group inequality Polarization index (Basu 2009) as ratio of between group inequality in total inequality (within group inequality + between group inequality) Composite measure Composite index (Basu, Klein and Nagar 2005; and Nagar and Basu 2002), a weighted average measure of standardized indicators for each country for each period defined Using a multivariate statistical method of latent variable Higher values of indices imply higher/better quality Regression analysis Dep. var: Gini index, Indep. vars: Institutions, policies, geography, etc OLS, 2SLS, Panel Data/GMM 14

15 Human capital and Policies Measuring by using indicators Human Capital Adult literacy, Combined enrolment, Mean years of schooling & education expenditure Macroeconomic Policies: Inflation, Real exchange rates, Current account & public debt Financial Market Policies: Liquid Liabilities, Financial System Deposits and Private Credit Trade Policies: Tariff, Peaks (international & national peaks) & Specific rates 4 indicators to reflect the effective foreign market access Institutions: Economic (Law & Order, Corruption, Regulations), Social (Civil liberties, Women s rights & empowerment, and Political (Political rights, democracy, decentralisations) Institutions 23 Indicators to capture comprehensive nature of institutions 15

38 Conclusions and way forward 38

39 1: Key messages 39

40 Policy messages Global analysis Income inequality increasing across countries and within countries in many regions Subregional variations remain critical Polarization among developing and developed countries continues Income gap across regions show disturbing trends: Asia-Pacific declining Africa significantly increasing Western Asia increasing recently Europe some increase Americas low Investment in education is key to reduce income inequality Policies and institutions need to be strengthened 40

41 2: Suggested research tasks 41

42 Inequality research Data and policy research Inequality computation Gini index (1912) got several limitations though most widely available Palma measure (2006): Ratio of top 10% to ration of poorest 40% of population Still lacks to compute inequality in education, health and other forms of asset globally in the time series format Measurements and comparability of income Gini inequality measures due to definition, sources and household survey information Need to formulate statistical framework to standardised, UN Task Team on inequality: ECE,ESCAP,DESA,UNICEF, UNRISD, UN Women Impact assessment of inequality Need model framework to capture and analyse impact of income as well as other forms of social inequalities Inequality, macro modelling and sustainable development 42

43 3:Global Agenda on Inequality 43

44 Equality for shared prosperity Realizing the Future We Want for All A moral duty, a political necessity, and an imperative for the due protection of human rights ESCAP/ADB/UNDP Asia-Pacific Regional MDG Report 2012/13 Inequality issue was one of the key policy message that came out from Asia-Pacific sub-regional stakeholders consultations on post-2015 development agenda The Secretary-General's High-Level Panel of eminent persons on the Post-2015 Development Agenda, noted that Yet inequality remains and opportunity is not open to all. If inequalities continue to widen, development may not be sustainable Reducing inequality will need great transformative change Globally (in) equity is emerging as a central plank in discussions on the United Nations post-2015 development agenda 44
