The Malmquist Index methodology is widely used in production economics for measuring the productivity changes of a set of decision making units (DMUs) within different time periods. Moreover, it is quite usual in the management literature to compare public and private DMU performance operating under the same economic sector. However, the standard Malmquist index needs a panel database to be imp...

the aim of this paper is to generalize the‎‎notion of pseudo-almost valuation domains to arbitrary‎ ‎commutative rings‎. ‎it is shown that the classes of chained rings‎ ‎and pseudo-valuation rings are properly contained in the class of‎ ‎pseudo-almost valuation rings; also the class of pseudo-almost‎ ‎valuation rings is properly contained in the class of quasi-local‎ ‎rings with linearly ordere...

Panel data are rarely available for developing countries. Departing from traditional pseudo-panel methods that require multiple rounds of cross-sectional to study poverty mobility at the cohort level, we develop a procedure works with as few two survey and produces point estimates transitions along welfare distribution more disaggregated household level. Validation using Monte Carlo simulations...

in this paper, some results of the chebyshev type integral inequality for the pseudo-integral are proven. the obtained results, are related to the measure of a level set of the maximum and the sum of two non-negative integrable functions. finally, we applied our results  to the case of comonotone functions.

This article analyzes the recent returns to human capital in Colombia. Using a pseudo-panel approach, results show return of 9.7% from 2016 2020. Comparisons with previous data reduction approximately 5 p.p. on capital. Our importance investing Colombia’s due positive externalities compared other forms investment Also, we find statistically significant differences between men and women; Around ...
