The time limit to reach the goals of the 2030 Agenda is now just eight years away. It is vital to pursue a new model of partnerships, based on coordinated responses, if we are to reach our international commitments and reduce inequality for all by building sustainable, inclusive and resilient...
Journal Article
This study re-examines the determinants of redistribution in light of improved data and methods relative to earlier literature. In particular, we use the latest version of the UNU‐WIDER’s Income Inequality Database to have the best available estimates of both pre‐ and post‐redistribution inequality...

– How large is the effect of top incomes?
Despite the growing interest in global inequality, assessing inequality trends is a major challenge because individual data on income or consumption is not often available. Nevertheless, the periodic release of certain summary statistics of the income distribution has become increasingly common...

The interest in the level of global inequality has surged in recent years. This paper complements existing estimates of global inequality by providing the first estimates of the level of bipolarization of the global income distribution. During 1975–2010, global bipolarization declined substantially...

Journal Article
This paper investigates the process of adjustment in employment. A dynamic model is applied to a panel of six Tunisian manufacturing industries observed over a period of 25 years, from 1971 to 1996. Industries are assumed to adjust their labor inputs toward a desired level. A labor requirement...

– How large is the effect of top incomes?
In this paper, we estimate the recent evolution of global interpersonal inequality and examine the effect of omitted top incomes on the level and direction of global inequality. We propose a methodology to estimate the truncation point of household surveys by combining information on income shares...

– A bridge between micro and macro estimates?
The Nordic model relies on high tax rates to finance an extensive welfare state. If labour supply elasticities are large, the burden of financing the model can be large even if, arguably, the practice of providing subsidised goods that support labour supply is likely to mitigate these effects. We...

– A counter-argument to the recommendation in the Mirrlees Review
The Mirrlees Review recommends that commodity taxation should in general be uniform, but with some goods consumed in conjunction with labour supply (such as child care) left untaxed. This article examines the validity of this claim in an optimal income tax framework. Contrary to the recommendation...
This paper examines the effects of health-oriented food tax reforms on the distribution of tax payments, food demand and health outcomes. We offer an illustration of how one can take into account the uncertainty related to both demand estimation and health estimates and to produce confidence...
– Economywide Analysis for Ethiopia and Uganda
Rapid urbanization is an important characteristic of African development and yet the structural transformation debate focuses on agriculture’s relative merits without also considering the benefits from urban agglomeration. As a result, African governments are often provided conflicting...
– Evidence from a Group-Based Aid Project in Mozambique
This paper evaluates the impact of an intervention to improve farming techniques and food security in the Gaza area of rural Mozambique. We examine the impact of a group-based approach to technology adoption in subsistence agriculture, using panel data collected by our research team on over 200...
Fish stocks around the world are heavily overexploited in spite of fishing policies in several parts of the world designed to limit overfishing. Recent studies have found that the complexity of ecological systems and the diversity of species, as well as negative impact of fishing activities on...
– An Empirical Analysis
The theoretical analysis of optimal commodity taxation is advanced, but there is only limited empirical evidence to guide commodity tax policies. With this paper, we contribute to this body of literature by empirically examining, using Finnish consumption data, the relation between working hours...

– Views from Africa
Although development generally refers to a broad concept, the quest for development in Sub-Saharan Africa has been biased by ideological considerations which made abstraction of local conditions and people’s aspirations. The prevalent development models have used increased national income as a...
