Anomalías en la autocorrelación de rendimientos y la importancia de los periodos de no transacción en mercados latinoamericanos

This paper aims to determine the evidence of returns autocorrelation for the main Latin American stock markets, and the influence of the day of the week effect on this phenomenon. Also, we analyze the importance of non-trading periods and their incidence on stock markets returns. We determine a high autocorrelation in most of the stock markets analyzed, both in local and global currency and the day-of-the-week effect on only some of the stock markets. Evidence of correlation between trading periods returns and those of non-trading periods is also found.     

Atributos de calidad del servicio de la telefonía móvil para clientes mexicanos y su impacto en la satisfacción y en la lealtad hacia la marca

The objective of this study is to identify relevant attributes of service quality in mobile phones for Mexican customers and to establish their impact on customer satisfaction and brand loyalty. It is being assumed that the attributes of service quality are an antecedent of satisfaction and loyalty. The study is divided in two phases. In a first qualitative phase, thirteen attributes were detected using in-depth interviews. In a second quantitative phase, these attributes were empirically contrasted with variables of satisfaction and loyalty. It was found that only six attributes are statistically related to the variables of these constructs, with two of them being the most relevant: price per minute and empathy perceived by customers from company’s employees.     

Medición de la intensidad en el uso de las tecnologías de la información y la comunicación en Escandinavia

One characteristic of the processes related to technological innovation in the Scandinavian countries is the high participation level of public and private agents. The objective of this strategy is to assimilate knowledge and to spread it out in the best possible way. Thus, in this article we identify the profile of ICT users; we try to establish how important they are for these countries, their good use of these technologies and how they impact on their communication processes. The results derived from the research prove that: 1) Swedish and Danish homes are a reference when it comes to the utilization of ICTs, 2) Finnish companies lead the way in the adoption of ICTs, followed by Danish and Swedish companies; 3) When it comes to provision and implementation of public services on a technological platform, the leading countries are Denmark, Finland and Sweden; and 4) When it comes to the utilization of ICTs in infrastructures, the EU leadership is headed by Sweden and Denmark, far ahead from the other Member States.     

Acceso y uso de los mercados financieros para el pago de los gastos de la educación básica

The aftermath of the 2008 financial crisis and the macroeconomic adjustment that followed provided higher unemployment and eroded the Mexican households’ purchasing power. Though, families had to continue financing education expenditures, sometimes borrowing in the formal or informal financial market. The hypothesis of this paper posits that access and use of formal and informal financial products can reduce the financial problems associated with basic school private expenditures. The probit model is estimated through a sample of four hundred households drawn from the municipality of San Pedro Cholula (state of Puebla). The results indicate that a worsening of working conditions and sudden unemployment are associated with an increased likelihood of difficulties in making ends meet. Moreover, accessing the formal financial market lessens the likelihood of such problems, but for the informal counterpart results depend on the characteristics of each financial intermediary.     

Mapas cognitivos difusos para la selección de proyectos de tecnologías de la información

The evaluation and selection of information technology projects is one of the most complex decision-making processes. To achieve alignment between projects and strategy is very important to analyze the goals and processes inside the organization. This paper presents a model for the selection of IT projects, based on the analysis of enterprise architecture. The proposal makes use of causal relations modelling using fuzzy cognitive maps. This approach facilitates the evaluation and selection of a project portfolio in order to achieve the desired future state of enterprise architecture. The model represents an attractive alternative or complement to existing methods in the evaluation of IT initiatives. A case study showing the application of the model to a professional services organization for the transformation of the enterprise architecture is shown.     

Aprendizaje,innovación y gestión tecnológica en la pequeña empresa: Un estudio de las industrias metalmecánica y de tecnologías de información en Sonora

In the industrial development in Northwestern Mexico stands out the limited capacity of local firms to integrate into the global value chains and there is an emergent participation of the metalworking sector and information technology as suppliers of goods and services for large exporters. Recent local researches analyze the accumulation of technological capabilities, but they have not researched the relationship with technology management strategies. This paper presents the results of an empirical study of micro, small and medium enterprises in such areas, which allows the guessing of a direct correlation between the level of accumulated skills and the level of technology management.     

Administración del riesgo crediticio al menudeo en México: una mejora econométrica en la selección de variables y cambios en sus características

The early prediction of bad debtors in revolving loans in Mexico is a relevant current issue. The proposed econometric model of behavioral scoring considers the changes in the characteristics of consolidated clients and produces better results than those obtained with methodology used by the CNBV on provisions. The obtained results show the possibility of replacing the current model, minimizing the expected loss and increasing the ROA of Mexican financial institutions in 2.20% complying the methodology and statistical testing criteria according to the Unique Banking Dispositions and the guidelines of Basel II on credit risk.     

Avances en la cantidad de la información financiera del sector público en México a raíz de la LGCG

We evaluate the quantity, quality and harmonization of the financial information published by the states, the Federal District and the federal government during the period 2008 to 2012, following the approval of the General Law on Government Accounting (LGCG). First, the requirements identified by the CONAC and subsequently the International Accounting Standards Public Sector 1 (IPSAS) are used to assess the publication of the financial statements. Second, we presente the rate of compliance with the publication of accounts pointing IPSAS 1, 2 and 17. Finally, the harmonization of financial statements is studied by the Herfindahl-Hirschman index to determine whether the financial statements are comparable between them. The results indicate that the public sector has increased the quantity, quality and harmonization of the financial information published.     

Reflexiones teóricas en torno a la propuesta de recuperación del poder de compra del salario mínimo en México

Regarding the recent proposal made by the Mexico City Government about the recovery of the purchasing power of the minimum wage, some reflections on the theories of production and distribution are proposed. We first review the seminal paper written by Cobb and Douglas (1928). Some obstacles in measuring the marginal factor products, and a pair of inconsistencies between the theories of production and distribution on the one hand, and some exercises of quantifying “productivities” on the other hand, are presented. Finally, a model of imperfect competition, which displays the dispute over income between economic agents, is included. One conclusion is that income distribution does not follow a simple rule, but a bargaining process based on market power in a historical context that provides inertia and in which institutions play a key role.     

Validez y confiabilidad de la escala de justicia organizational de Niehoff y Moorman en población mexicana

The objective of this research was to perform the adaptation to Spanish of the organizational justice scale of Niehoff and Moorman (1993) focused on measuring three factors of justice: distributive, procedural and interactional. The method used to adaptation the scale consisted of eight stages: translation of the items by reverse translation method, validation by judges, scale integration, application of the scale to a sample of 1296 workers (45.45% female and 54.6% male), items analysis, reliability analysis, construct validity using confirmatory factor analysis and structural equation analysis, and integration of the adapted version of the scale. The results confirm the three-dimensional factor structure of the scale: distributive justice, procedural and interactional, with high internal consistency which ensures the psychometric quality of the scale.     

Análisis del comportamiento estadístico y aproximación fractal en la recaudación del impuesto sobre nóminas y asimilados en el estado de Quintana Roo

This paper analyzes the tax collection from payroll tax on staff and non-staff in the state of Quintana Roo from 2000 to 2010. Its main contribution is to identify the statistical revenue behavior using a fractal approach, establishing iterative patterns at both state and municipal level, for the entire analyzed series of 132 months as well as shorter time periods. It serves as a trigger for application in other locations and charges in order to explore some features of taxation. Two statistical criteria were used to determine normal or abnormal series of municipal tax collection during the study period, namely, the Empirical Rule criteria and parameters using Chebyshev’s theorem. As a contrast, the Jarque-Bera test was applied on residuals, concluding that the fiscal revenue from the state of Quintana Roo (municipal data) does not follow a normal distribution, which is why the fractal approach has been used. The results with data for tax collection by municipalities throughout Quintana Roo show the presence of a fractal behavior (repetitive and cyclic) in revenue, which can be interpreted as the presence of a consolidated tax base, thus justifying the conclusion that there is strength (the observed level of collection) in local public finances. The same conclusion is obtained, with different temporal cuts, when analyzing and detecting the presence of specific fractal revenue behavior observed in municipalities of Benito Juarez (Cozumel) and Othon P. Blanco from 2000 to 2010.     

Evaluación de la conversión a café orgánico usando la metodología de opciones reales

Since the deregulation of the coffee market in 1989, price crises are proof of the uncertainty and risk around coffee growers’ income, particularly for small producers who, in the case of Mexico, have taken action such as the conversion of their traditional crops into the organic production system which, besides the ecological priority, allows them to get a higher income than from conventional coffee. In this document we model as real investment options (RIO) the possibility of conversion from one system into the other one also including the feasibility of abandoning this strategic decision.     

Aplicación de análisis discriminante para evaluar la productividad como resultado de la certificación BASC en las empresas de la ciudad de Cartagena

This research paper presents the evaluation of productivity in companies in the city of Cartagena as a result of the certification of said companies in the Business Anti-Smuggling Coalition (BASC). The methodology used calculated productivity indicators at 23 companies certified at BASC. Next, we used the Discriminant Analysis technique to explain the belonging and discrimination of each group of productivity indicators evaluated, resulting in the correlation between certified companies and increased productivity indices for 2008 and 2010. From the discriminant function obtained and the statistics analyzed, it can be concluded that certification in BASC standard showed no improvement in the indicators selected, but presented significant differences in the Gross Profit / Value Added (IP1), Operating Income / Operating Capital (IP5) and Net Income / Operating Capital (IP6) indicators.     

La empresa familiar en México Situación actual de la investigación

Family businesses are fundamental productive structures in industrialized and developing economies. Even though there are no rigorous data to support the fact, family businesses have a relevant influence in the generation of national wealth, but they are not well known. Research on family enterprise has been recent; in this article we aim to reconstruct the state of the art research that has been undertaken in Mexico since the main objective of this paper is to encourage family business research. The results presentation is inspired by Chua et al. (1999), Low and MacMillan (1988) and Sharma’s works (2004).     

Evolución de la capacidad tecnológica en México. Aplicación del análisis estadístico multivariante de cluster

This paper conducts an analysis on the existence of state clusters related with technological capabilities in Mexico. An empirical study was conducted using the technique of multivariate statistical cluster analysis, based on the set of indicators proposed by Cepal (2007), collecting data from various public sources country for 2006 and 2012 in order to study the time evolution of such clusters, trying to see what states have been moving to a cluster located in positions more which have advanced and retreated over the period. The results show the existence of 7 groups of states characterized by different technological capabilities, plus states are identified in decline and progress, both in terms of absorptive capacity and innovation, and in relation to the technological infrastructure capabilities.

Gobierno corporativo,financiamiento y género: un estudio de las pymes emisoras de títulos en los mercados de valores argentinos

The aim of this work is to study corporate governance (CG) in small and medium enterprises (SMEs) from a gender perspective. In particular, we study the participation of women in ownership, management (board and senior management) and external audit in SMEs participating in the Argentinean Securities Market. The results show that participation of women in ownership and in external audit has a significant relationship with financing decisions. However, we do not find evidence of relations among different levels of GC and gender.     

Simulación de la tasa de reciclaje de productos electrónicos Un modelo de dinámica de sistemas para la red de logística inversa

Current trends in the development and innovation of information technologies and shorter life cycles of electronic products have resulted in the generation of large amounts of waste (e-waste) which can potentially cause environmental problems due to the toxicity of some of their components. The e-waste problematic has attracted the attention of governments, companies and consumers that look to identify strategies for the management and proper disposal of e-waste with the goal to protect the environment. This work uses the methodology of system dynamics to simulate how the rate of products returned by individuals and the amount of computers recovered in an open-loop reverse supply chain, varies under different scenarios. The simulated scenarios correspond to the possible combinations of five macro factors: rate of innovation and product life cycle, information available to consumers about e-waste recycling, legislation, e-waste programs structure along with diffusion and publicity efforts. The results of the simulation are relevant to identify over which factors it is convenient to intervene to increase the amount of recycled computers because this amount represents a reduction in the volume of e-waste and an enterprise opportunity to generate earnings from recycling computers.     

Empleo manufacturero en la Región Centro de México. Una estimación por gran división

In this paper, the production performance by great division and its effects on formal job generation in the central region of Mexico is analyzed. The more dynamic manufacturing divisions are identified and with the estimation of an employment function with panel data for each of the nine manufacturing great divisions, it is found that divisions I. Food, beverages and tobacco, II. Textiles, clothing and leather industry, III. Wood and wood products and IX Other manufacturing industries exhibit a high income elasticity of employment (0.716, 1.035, 0.781 and 0.94) and that the more technical divisions, with greater innovation processes and highly exporting divisions such as division VIII. Metal products, machinery and equipment show a lower elasticity.
