Ken Arrow (1998) asks, “What has economics to say about racial discrimination?” He replies – entirely correctly – that racial “segregation within an industry – that is, firms with either all black or all white labor forces” – may be explained by economic theory, but “the...

This paper studies the Pareto-optimality of the consensual optimum established in "Allais-anonymity as an alternative to the discounted-sum criterion I: consensual optimality" (Mabrouk 2006a). For that, a Pareto-optimality criterion is set up by the application of the generalized Karush, Kuhn...

The paper aims to describe the evolution part of the economy and power to tax in Colombia. It also explains the failure of the government and the problems that have expanded public sector expenditures. Furthermore, we identify the aspects of political economy have influenced the evolution of the...

In this work we analyse social welfare relations on sets of infinite utility streams that verify various types of liberal non-interference principles. Earlier contributions have established that (finitely) anonymous and strongly Paretian quasiorderings exist that agree with axioms of that kind...

We are concerned with the problem of aggregating infinite utility streams and the possible adoption of consequentialist equity principles when using numerical evaluations of the streams. We find a virtually universal incompatibility between the Basu-Mitra approach (that advocates for social...

A cake is a metaphor for a heterogeneous, divisible good, such as land. A perfect division of cake is efficient (also called Pareto-optimal), envy-free, and equitable. We give an example of a cake in which it is impossible to divide it among three players such that these three properties are...

In this paper I will analyse the redistribution of income amongst n generations using the Single-mindedness Theory. I will introduce a new expression for the balanced-budget constraint, no longer based on lump- sum transfers as in the traditional literature, but rather on more realistic labour...

`Relative Utilitarianism' (RU) is a version of classical utilitarianism, where each person's utility function is rescaled to range from zero to one. As a voting system, RU is vulnerable to preference exaggeration by strategic voters. The Groves-Clarke Pivotal Mechanism elicits truthful...

We establish a Theorem on Structural Inequality Indices which provides fundamental link between inequality measurement and a concept of social justice embedded in meritocracy framework by taking axiomatic approach and redefining standard properties of inequality indices in a way that...

The Clarke Pivotal Voting Mechanism (CPVM) elicits truthful revelation of utility functions by requiring any `pivotal' voter to pay a monetary `Clarke tax'. This neglects wealth effects and gives disproportionate power to rich voters. We propose to replace the `Clarke tax' with a lottery,...
