This paper offers a unifying conceptual framework for understanding the relationship between climate change and “within-country inequalities,” referred here collectively as “social inequality.” Available evidence indicates that this relationship is characterized by a vicious cycle, whereby initial inequality causes the disadvantaged groups to suffer disproportionately from the adverse effects of climate change, resulting in greater subsequent inequality. The paper identifies three main channels through which the inequality-aggravating effect of climate change materializes, namely (a) increase in the exposure of the disadvantaged groups to the adverse effects of climate change; (b)…

Economic development is associated with structural transformation and the increase of complexity of production and exports. This paper examines whether strategic diversification is required to increase economic complexity or whether market incentives would be sufficient to drive this process of catching-up. The paper applies empirical methods of the strand of the literature on economic complexity to examine how path dependency and the demand for potential new products affect economic diversification. It argues that strategic diversification is required in cases when demand factors are very likely to create incentives for diversification towards less complex products, which hinders the…

Economic diversification is very relevant for poorer developing countries to create jobs and foster economic development. That need has been recognized in key internationally agreed development goals. The empirical economic literature has identified several stylized facts about the pattern of diversification of economies, but the development of explanations for those patterns in general has been only loosely associated with economic theory on growth, trade, technology change and structural transformation. Making that connection is relevant because it could inform policymakers in developing countries in designing and implementing policies for promoting diversification. This paper presents…

This paper maps interrelationships among targets of the Sustainable Development Goal dedicated to oceans (SDG 14), as well as interrelationships between those targets and other SDGs. This is done using a large number of UN reports as well as scientific publications. The literature identifies many linkages among the targets of SDG 14; most of these targets are potentially synergistic with one another. Many linkages also exist between SDG 14 targets and other SDGs. Different targets under SDG 14 link to different SDGs. This has implications for policy discussions on how to achieve progress on SDG 14. The interrelationships that we highlight can be used as a tool for dialogue between policy…

In 2015, a set of Sustainable Development Goals (SDGs) will succeed the Millennium Development Goals as reference goals for international development for the period 2015-2030. Education was identified as a standalone goal (SDG4). Epistemic communities have documented a number of links between education and other SDG areas, and policy makers have long recognized many of them. Based on an exhaustive content analysis of 40 global reports, this paper examines how well such links are represented in flagship publications of the United Nations system. Taken together, the reports identify links between education and all the SDGs, with the notable exception of SDG 14 on oceans. For most of the…

In light of the emphasis on “inclusion” in the Sustainable Development Goals (SDGs), this paper contends that social exclusion and inclusion are context-dependent concepts in at least three senses. First, the ideal of an inclusive society varies by country and by region. Second, different places have different histories, cultures, institutions and social structures. These influence the economic, social and political dimensions of social exclusion and the interplay among them. Third, context – where one lives – shapes access to resources and opportunities. Social inclusion is thus spatially uneven. The paper also shows how context matters, identifying some of the mechanisms by which…

This paper synthesizes the evidence of a negative correlation between income inequality and environmental quality. It shows that inequality exerts adverse impact on environmental outcomes through several channels, including the household, community, national, and international channels. These channels however overlap with one another and can thus reinforce the impact of inequality. Other dimensions of inequality, in particular gender inequality, also impact environmental quality negatively. The concept of the Environmental Kuznets Curve (EKC) is not that helpful in explaining the negative correlation between inequality and environmental quality. The findings of the paper suggest that…

This paper revisits the earlier assessments of the Palma Proposition and the ‘Palma Ratio’. The former is a proposition that currently changes in income or consumption inequality are (almost) exclusively due to changes in the share of the richest 10 per cent and poorest 40 per cent because the ‘middle’ group between the richest and poorest always capture approximately 50 per cent of gross national income (GNI). The latter is a measure of income or consumption concentration based on the above-mentioned proposition and calculated as the GNI capture of the richest 10 per cent divided by that of the poorest 40 per cent. In this paper we do the following: note the use already being made of…

China has departed from the East Asian model of development by letting inequality to rise to a high level, which is contributing to China’s current problems of macroeconomic imbalance, declining efficiency of capital, and rising social tensions. If inequality persists, China may get caught in the “inequality-trap,” which may then lead it to the “middle income trap (MIT).” Fortunately, China still has the levers to pull to reduce inequality and avoid MIT. Measures along both the “wage route” and the “redistributive route” can be adopted for this purpose. In addition, China may pursue the “cooperative route” to more equitable distribution.

In 2014, UN Member States proposed a set of Sustainable Development Goals (SDGs), which will succeed the Millennium Development Goals (MDGs) as reference goals for the international development community for the period 2015-2030. The proposed goals and targets can be seen as a network, in which links among goals exist through targets that refer to multiple goals. Using network analysis techniques, we show that some thematic areas covered by the SDGs are well connected among one another. Other parts of the network have weaker connections with the rest of the system. The SDGs as a whole are a more integrated system than the MDGs were, which may facilitate policy integration across sectors…

We introduce two separate datasets (The Global Consumption Dataset (GCD) and The Global Income Dataset (GID)) containing an unprecedented portrait of consumption and income of persons over time, within and across countries, around the world. The benchmark version of the dataset presents estimates in PPP units of monthly real consumption and income for every decile of the population (a ‘consumption/income profile’) for 133 countries and more than half a century (1960-2012). We describe the construction of the datasets and demonstrate some possible uses by presenting preliminary results concerning the consumption distribution, poverty and inequality for the world and specific country…

Analyses of redistributive policies often focus on income flows to examine the nexus between redistribution and economic growth. With strengthening signs of growing economic inequality in many countries, an increasing number of economists investigated the existence and nature of a hypothetical trade-off between economic growth and equity. As signs of unsustainable development are strengthening more generally, this paper proposes to look at the broader nexus between redistribution, equity and sustainable development, emphasizing its social and environmental dimensions. It does so by first proposing an analytical framework defining the role of redistributive policies in shaping the private…
