This paper introduces and characterizes the number-sensitive critical-level generalized utilitarian family of population principles which is a generalization of the critical-level generalized-utilitarian family. Number-sensitive critical-level utilitarian principles rank alternatives by using a...

We provide characterizations of a class of rank-mobility measures and of a specific member of this class. These measures are based on the Kemeny distance for orderings. We use the well-known replication-invariance property to ensure that our measures are applicable in variable-population...

We propose and characterize a generalization of the classical linear index of individual deprivation based on income shortfalls. Unlike the original measure, our class allows for increases in the income of a higher-income individual to have a stronger impact on a person’s deprivation the...

We examine the measurement of multidimensional poverty and material deprivation following the counting approach. In contrast to earlier contributions, dimensions of well-being are not forced to be equally important but different weights can be assigned to different dimensions. We characterize a...

We introduce a one-parameter class of individual deprivation measures. Motivated by a suggestion of Runciman, we modify Yitzhaki’s index by multiplying it by a function that is interpreted as measuring the part of deprivation generated by an agent’s observation that others in his reference...

We provide a characterization of selection correspondences in two-person exchange economies that can be core rationalized in the sense that there exists a preference profile with some standard properties that generates the observed choices as the set of core elements of the economy for any given...

We provide a systematic treatment of the notion of economic insecurity, assuming that an individual’s sentiment of insecurity depends on the current wealth level and its variations experienced in the past. We think of wealth as a comprehensive variable encompassing anything that may help in...

We examine the measurement of individual poverty in an intertemporal context. In contrast to earlier contributions, we assign importance to the persistence in a state of poverty and we characterize a class of individual intertemporal poverty measures reflecting this feature. In addition, we...

We show that if patent protection and trade secrecy generate asymmetricmarket structure, an innovator may prefer patent protection than trade secrecy even ifthe diffusion probability is higher under the former but it increases marketconcentration by preventing some imitators...
