Application de la théorie collective du risque à la réassurance « Excess-Loss »

Abstract

Introduction.

Les méthodes de calcul de la prime de réassurance Excess-Loss utilisées jusqu'à présent ou bien avaient un caractère purement empirique, ou bien présumaient que les écarts entre le montant des sinistres constatés et le montant des sinistres attendus se répartissent suivant la loi de Laplace-Gauss.     

Sur la notion de prime d'épargne

Abstract

Il est bien connu que la réserve mathématique W (t) d'une assurance très générale sur la vie satisfait à une équation différentielle de Thiele, à savoir où l'on a

• δ (t) = le taux instantané ou l'intensité d'intérêt,

• μ (t) = l'intensité de mourir,

• P (t = la prime par unité du temps,

• S (t) = le capital assuré en cas de décès.

     

Impacto de las Normas de Información Financiera en la relevancia de la información financiera en México

In this study, it is shown that the value relevance of the financial information, measured by the coefficient of determination (R²), has improved as consequence of the changes in the financial reporting standards. It is applied the Ohlson model (1995) with accounting variables (earning per share and book value) and the stock market price of Mexican stock market companies, during the period from 1992 to 2010. The econometric results are obtained applying an Ordinary Least Squared Regression Analysis and a Panel Data Analysis. The sample is divided in two periods, before and after the foundation of CINIF, and the Chow test is applied to confirm the existence of a structural change. The book value variable is consistently significant in both periods. The Ohlson model is also applied to sub-samples which distinguish the firm for its size, for belonging to the Food and beverages industry and for its classification as Tangible and Intangible firms.     

Atributos relevantes de calidad en el servicio y su influencia hacia la lealtad de marca en la industria aseguradora de automóviles en México

The objective of this study is to identify key quality service attributes in the automobile insurance business and determine their influence on brand loyalty. In this study distinction is made between the service during the hiring of the service and the service provided after an accident. In a preliminary exploratory inquiry quality service attributes were identified with the application of in-depth interviews. In an empirical study, hypothesis related to a direct relationship between the attributes and several measures of brand loyalty are contrasted. A sample of n = 210 of automobile insurance clients was conformed. Five regression models were developed for the data analysis, one for each loyalty measure. These analyses allowed a specific detection of significant attributes for each case. Though it is concluded that attributes related to the service after the accident have a higher degree of influence on the customer loyalty, it is found that a particular attribute during hiring (reputation of the insurance company) also has an important role.     

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.     

Efectos de la contratación de exempleados de multinacionales en la capacidad de absorción en empresas locales

Attracting Foreign Direct Investment seeks, among other goals, increase productivity of local firms through knowledge spillovers. Nevertheless the empirical evidence is contradictory. One influential factor is the absorptive capacity of local firms. This article analyzes the effect of the presence of ex-employees of multinational companies, as employees of local firms in the absorption capacity of these firms. The study was conducted in Costa Rica, a country recognized for its successful strategy in this area. The data come from a survey of 1,167 companies conducted by the Costa Rican Observatory of Small and Mediums Enterprises in 2011. It was found that hiring former employees of multinational companies by local firms has a positive effect on the rate of absorption capacity. In short, this engagement of former employees of multinationals increases by nine percentage points the rate of absorption capacity, with differences for sectors and firms sizes.     

La eficiencia técnica de los bancos durante la crisis Caso aplicado a la rentabilidad de la banca comercial en México y Chile

This paper aims to determine evidence about the efficiency of commercial banks under crisis periods when compared against their regular operating periods. Particularly, the Chilean and Mexican banking industries are reviewed by an innovated Data Envelopment Analysis (DEA) methodology. Conclusive evidence of an increase in efficiency for the incumbent banks under crisis periods is presented, as measured by their Return on Assets (ROA) and Return on Equity (ROE). Finally, evidence is found showing that when considering the banks that are more efficient during the whole period of analysis, their better performance is focused during the crisis periods, measured by their ROA and ROE as performance indexes. In most cases, banks that were more efficient during the previous-to-crisis period, had a lower performance during the crisis periods.     

Contraste de la ley de Gibrat en la banca comercial brasileña

In recent years Brazil has been one of the countries with major changes in the banking sector. The deregulation process that has taken place since 2002 has brought an increased presence of foreign banks and higher competition, among other aspects. In this context, the objective of this study is to analyze Gibrat's law on Brazilian commercial banks over the period 2002-2013 with the aim of providing evidence for the construction of a banking growth model which guide the country's financial policy. To that end, we employ a methodology based on quartile regressions as a contribution to previous literature. Our overall results reveal the existence of a non-lineal relationship between growth and banks size with an inverted U-shape. These findings allow us to affirm that the relative dispersion of banks size, as well as the sector's concentration, will be reduce in the future years.     

Los efectos de largo plazo de la asimetría y persistencia en la predicción de la volatilidad: evidencia para mercados accionarios de América Latina

This article proposes an extension to the CGARCH model in order to capture the characteristics of short-run and long-run asymmetry and persistence, and examine their effects in modeling and forecasting the conditional volatility of the stock markets from the region of Latin America during the period from 2 January 1992 to 31 December 2014. In the sample analysis, the estimation results of the CGARCH-class model family reveal the presence of short-run and long-run significant asymmetric effects and long-run persistency in the structure of stock price return volatility. The empirical results also show that the use of symmetric and asymmetric loss functions and the statistical test of Hansen (2005) are sound alternatives for evaluating the predictive ability of the asymmetric CGARCH models. In addition, the inclusion of long-run asymmetry and long-run persistency in the variance equation improves significantly the out of sample volatility forecasts for emerging stock markets of Argentina and Mexico.     

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.     

Análisis de la histéresis del desempleo en México ante shocks macroeconómicos

This research presents the behavior of the Mexican unemployment rate and shows the dependence with own history and macro variables. The concept of hysteresis or persistence tries to separate this inertia in the unemployment rate and some macroeconomic and endogenous factors. The results show a high inertia in the Mexican labor market, justified by the monetary levels and the dependence of the investment levels, considering the shocks of exports that affect the unemployment in the long term.     

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.     

El concepto de poder en la administración

The objective of this work is to explore the concept of power in Administration. What we are interested in studying is the domination exerted from a dominant position in the organization formally established. In this paper we argue that what defines power is the legality, and what defines authority is legitimacy. In the first place we will have a brief discussion of the distinction between legality and legitimacy, in order to distinguish the concept of power from authority. Then, we analyze the concept of power, distinguishing the power that gives the dominant device from the power established in intersubjective relationships, which are defined as relationships of power. Finally, we perform a conceptual approach of the power in Administration and some criticism inherent to this form of domination.     

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).     

Estructura de propiedad y su efecto en la política de dividendos en el contexto mexicano

In this paper we focus on analyzing if the ownership structure has any effect on the dividend policy in the Mexican market. The decision to pay dividends is one of the key elements within corporate policy, since that dividend policy has an influence on the company value. Therefore, decisions such as adopting a growth policy of the company through the profits reinvestment or destine these profits to dividends pay, could be influenced by the ownership structure. We base our analysis on three types of ownership structure: families, institutions (mainly banks) and small blocks of shareholders. Our results show that the concentration of ownership in families has a negative influence on the dividends payment, while the presence of institutional shareholders has an inverse effect. This indicates that the presence of large shareholders different to families have a dissimilar effect on dividend policy. Our work contributes to the literature in the context of emerging countries such as Mexico, since much of the existing research has focused primarily in environments such as Europe or the United States, where markets are well regulated with widely distributed property.     

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.     

Efecto en la calidad de la información ante cambios en la normatividad contable: caso aplicado al sector real mexicano

The purpose of this paper is to examine whether changes in accounting standards improve value relevance of financial information on listed companies in Mexico. The research was conducted for the period 2000-2013 using a sample of 141 companies that report to the Mexican stock exchange using the methodology of panel data. Our findings show that changes in local regulations (generally accepted accounting principles) to internationally approved standards (financial reporting standards and international financial reporting standards) increase the value relevance and therefore the quality of information. The study shows that the accounting information with international financial reporting standards is more trustworthy for foreign and national investors.
