The ordered weighted average inflation

This paper introduces the ordered weighted average inflation (OWAI). The OWAI operator aggregates the information of a set of inflations and provides a range of scenarios from the minimum and the maximum inflation. The advantage of this approach is that it can provide a flexible inflation formula that can be adapted to the specific characteristics of the enterprise, region, state or country (...

Using Ordered Weighted Average for Weighted Averages Inflation

This paper presents the ordered weighted average weighted average inflation (OWAWAI) and some extensions using induced and heavy aggregation operators and presents the generalized operators and some of their families. The main advantage of these new formulations is that they can use two different sets of weighting vectors and generate new scenarios based on the reordering of the arguments with the weights. With this idea, it is possible to generate new approaches that under- or overestimate the results according to the knowledge and expertise of the decision-maker. The work presents an application of these new approaches in the analysis of the inflation in Chile, Colombia, and Argentina during 2017

A new measure of volatility using induced heavy moving averages

The volatility is a dispersion technique widely used in statistics and economics. This paper presents a new way to calculate volatility by using different extensions of the ordered weighted average (OWA) operator. This approach is called the induced heavy ordered weighted moving average (IHOWMA) volatility. The main advantage of this operator is that the classical volatility formula only takes into account the standard deviation and the average, while with this formulation it is possible to aggregate information according to the decision maker knowledge, expectations and attitude about the future. Some particular cases are also presented when the aggregation information process is applied only on the standard deviation or on the average. An example in three different exchange rates for 2016 are presented, these are for: USD/MXN, EUR/MXN and EUR/USD

Situación actual de la competitividad y sustentabilidad y el COVID-19

Thinking about what the future will be is not an easy task. The year 2020 has greatly marked the meaning of our lives, modifying all social, economic, and environmental dynamics. At the end of the last century, the United Nations (UN) in its publication "Our Common Future" (1987) warned of an over-exploitation of natural resources as economic growth became the primary objective of countries (Costanza et al., 2014). Likewise, the UN proposed working simultaneously and with the balance in the economic, human, environmental, institutional and technological dimensions to ensure sustainability, where the mixture of these gave way to competitiveness through the optimization of resources, as well as the forms and actions of social, economic and political agents to achieve adequate and sustained growth and development (Lombana & Rozas, 2009).

A finales del siglo pasado la Organización de las Naciones Unidas (ONU) en su publicación “Nuestro futuro común” (1987) advertía una sobre explotación de los recursos naturales dado que el crecimiento económico se convirtió en el objetivo primordial de los países (Costanza et al., 2014). Así mismo, la ONU proponía trabajar simultáneamente y con equilibrio en las dimensiones económica, humana, ambiental, institucional y tecnológica para asegurar la sustentabilidad, donde la mezcla de estas daba paso a la competitividad mediante la optimización de los recursos, así como las formas y actuación de los agentes sociales, económicos y políticos para alcanzar un crecimiento y un desarrollo adecuado y sostenido (Lombana & Rozas, 2009).
