We propose a new method for estimating the power-law exponent of a firm size variable, such as annual sales. Our focus is on how to empirically identify a range in which a firm size variable follows a power-law distribution. As is well known, a firm size variable follows a power-law distribution...

The authors propose a new method for estimating the power-law exponents of firm size variables. Their focus is on how to empirically identify a range in which a firm size variable follows a power-law distribution. On the one hand, as is well known a firm size variable follows a power-law...

The isograph methodology is developed here with associated distributions, indicators of inequality, additional results, and is implemented on 53 LIS countries (with an annex covering 655 LIS country-year samples). The gb2 and other classical distributions (FC, Dagum, SinghMaddala) are presented...

This article considers the customer's trust and commitment variables in attaining the much desired brand loyalty. In this sense, the present study proposed to validate a theoric model composed of three pillars - trust, commitment and brand loyalty, which would be useful for companies with a...

Analysis has been made on whether the presidential administration of Mexico, which began in December 2018 with anti-neoliberal economic policies, has had an impact and to what extent whit respect to the collection of the payroll tax in the state of Quintana Roo and, as a contrast variable, the...

This paper presents an analysis of the implications it has on standard growth models assume an alternative hypothesis to the exponential growth of the population and how modeling time can alter the dynamic behavior of these models. An extension (in continuous time and discrete time) of the...

El objetivo de este artículo es medir el desempeño del trabajo formal en dos estados de México con vocación económica distinta: Quintana Roo cuya actividad principal es el turismo y Aguascalientes con actividad principalmente industrial. El trabajo se inicia presentando el contexto laboral...

This article analyses the Mexican exports to China and the European Union along with the effects of a possible shift of Mexican products to the above markets due to a change within the US-Mexico trade agreements. Beginning with a review of Mexican trade agreements with the European Union and...

Anwendung der Extremwerttheorie zur Quantifizierung von Marktpreisrisiken – Test der Relevanz anhand vergangener Extrembelastungen von DAX und MSCI Europe Ein Verfahren, das gezielt entwickelt wurde, um Risiken mit sehr geringen Eintrittswahrscheinlichkeiten zu quantifizieren, stellt die...

We propose a novel approach to model serially dependent positive-valued variables which realize a non-trivial proportion of zero outcomes. This is a typical phenomenon in financial time series observed at high frequencies, such as cumulated trading volumes. We introduce a flexible point-mass...
