Entrepreneurship and Economic Liberalization in the OECD Countries

Entrepreneurship displays remarkable differences across countries because of diverse factors. In this sense, it is frequently argued that economic liberalization encourages entrepreneurship. In this paper we address the extent to which economic freedom, understood as market economy oriented institutions and policies, matters for entrepreneurial activity through a panel data analysis for 78 countries during the period 2001-2012. We examine the relationship between the Fraser Institute’s economic freedom index and its five areas, and three entrepreneurial activity indicators from the Global Entrepreneurship Monitor, namely total entrepreneurial activity, necessity entrepreneurship and opportunity entrepreneurship. Economic freedom seems to increase opportunity entrepreneurship and decrease necessity entrepreneurship. Focusing on the OECD countries, we highlight that economic freedom is positively associated with entrepreneurship. In terms of entrepreneurship motivation, we find that a more flexible regulation of credit, labor and business, as well as entrepreneurial attitudes, may contribute to enhance opportunity entrepreneurship

Essays in Personal Transportation Demand and Consumer Finance

This dissertation is composed of three essays covering two areas of interest. The first topic is personal transportation demand with a focus on price and fuel efficiency elasticities of mileage demand, challenging assumptions common in the rebound effect literature. The second topic is consumer finance with a focus on small loans. The first chapter creates separate variables for fuel prices during periods of increasing and decreasing prices as well as an observed fuel economy measure to empirically test the equivalence of these elasticities. Using a panel from Germany from 1997 to 2009 I find a fuel economy elasticity of mileage of 53.3%, which is significantly different from the gas price elasticity of mileage during periods of decreasing gas prices, 4.8%. I reject the null hypothesis or price symmetry, with the elasticity of mileage during period of increasing gas prices ranging from 26.2% and 28.9%. The second chapter explores the potential for the rebound effect to vary with income. Panel data from U.S. households from 1997 to 2003 is used to estimate the rebound effect in a median regression. The estimated rebound effect independent of income ranges from 17.8% to 23.6%. An interaction of income and fuel economy is negative and significant, indicating that the rebound effect may be much higher for low income individuals and decreases with income; the rebound effect for low income households ranged from 80.3% to 105.0%, indicating that such households may increase gasoline consumption given an improvement in fuel economy. The final chapter documents the costs of credit instruments found in major mail order catalogs throughout the 20th century. This study constructs a new dataset and finds that the cost of credit increased and became stickier as mail order retailers switched from an installment-style closed-end loan to a revolving-style credit card. This study argues that revolving credit's ability to decrease salience of credit costs in the price of goods is the best explanation for rate stickiness in the mail order industry as well as for the preference of revolving credit among retailers.

Auditoría de sistemas al cumplimiento de los requerimientos 7, 8, 9 de la norma PCIDSS aplicada a Coral Hipermercado, Racar plaza con corte a Junio de 2015

Coral Hipermercado GO es una empresa dedicada a la comercialización de diversos productos de consumo masivo. Debido a la demanda que mantienen y el nivel de transacciones que realizan en ventas diariamente, ofrece diversas formas de pago entre ellas las tarjetas de pago, mismas que por la actual situación del auge de los sistemas informáticos y de la necesidad de la seguridad de los datos ante actos maliciosos las marcas de tarjetas de crédito han visto necesaria la implementación obligatoria (tanto en comercios como en las entidades intermediarias) de la Normativa PCI DSS. De esta manera, el servicio que brindan a los tarjetahabientes a más de ser mejorado, sea seguro en todas sus instancias. A través de nuestra investigación se obtuvo conocimiento de que la empresa Coral Hipermercado GO no ha realizado anteriormente una auditoria de la Normativa PCI DSS, por lo que la implementación de la Normativa podría no ser completa o apropiada, las políticas de la empresa pueden no contener los procesos y procedimientos que se deben llevar a cabo, haciendo que la seguridad de accesos a los datos de los titulares de tarjetas se vean vulnerables, de igual manera el manejo de las autenticaciones y la infraestructura de la seguridad física, misma que permite el resguardo de los equipos y por ende de la información. Se observó en la auditoría realizada a los requerimientos 7, 8, 9 de la Normativa PCI DSS que la misma no ha sido socializada en su totalidad, existen falencias en su implementación ya que el uso de las autenticaciones, accesos a los datos y seguridad física no son correctos, viéndose expuesta la información de los datos de los titulares de tarjetas de pago y la posibilidad de incurrir en pérdidas debido a probables actos maliciosos que se podrían encontrar expuestos en un futuro. Es imperativo mencionar que la norma ayudara al cumplimiento de los objetivos siempre y cuando se logren disminuir las falencias de su implementación o caso contrario se procederá a dar las recomendaciones necesarias respecto a los problemas encontrados para posteriores correcciones de forma que se mejore la gestión de la empresa.

CADENA DEL CAFÉ DE LOS SANTOS, COSTA RICA

Resumen La operación de las actividades económicas y su competitividad, analizadas desde una perspectiva de cadenas globales de mercancías, dependen del funcionamiento de los mercados de crédito, tanto nacionales como internacionales. La operación normal de los negocios requiere crédito para fortalecer sus recursos propios y hacer las compras de materia prima, insumos, pago de salarios e inversión. En todos los casos, el crédito puede ser utilizado para mejorar el diseño de productos, impulsar el acceso a nuevos mercados y aumentar la competitividad. A los productores de la región de Los Santos en Costa Rica se les reconoce por innovadores, y al café de la zona por ser un café de altura y de gran calidad. El artículo explora las necesidades de financiamiento de productores, beneficiadores y exportadores de café de Los Santos, sus fuentes de financiamiento y el uso dado a los recursos obtenidos. Entre las necesidades orientadas al mejoramiento de la competitividad se encontraron la renovación de cafetales entre los productores, el mantenimiento de proyectos y tecnología entre los beneficios y la generación de microbeneficios y búsqueda de nichos de mercado entre los exportadores. Abstract From a global commodity chains perspective, economic activities and their competitiveness depend upon the functioning of credit markets, both international and domestic. Current businesses operations require credit to enhance their own resources in order to buy raw material and inputs, pay wages and make investment. Credit may also be used to improve product design, enter new markets and boost competitiveness as a result. High altitude grown coffee from Los Santos, Costa Rica is widely known for its quality, and their growers as innovative. This paper addresses credit needs of coffee growers, processors and exporters in Los Santos, the credit sources they have access to, and the kind of uses the credit is given. Improving competitiveness uses of credit were found among growers, processors and exporters, such as crop and technology improvement, micro processing facilities and new markets search as well.

QoE-aware power management in vehicle-to-grid networks:a matching-theoretic approach

Frequency, time and places of charging and discharging have critical impact on the Quality of Experience (QoE) of using Electric Vehicles (EVs). EV charging and discharging scheduling schemes should consider both the QoE of using EV and the load capacity of the power grid. In this paper, we design a traveling plan-aware scheduling scheme for EV charging in driving pattern and a cooperative EV charging and discharging scheme in parking pattern to improve the QoE of using EV and enhance the reliability of the power grid. For traveling planaware scheduling, the assignment of EVs to Charging Stations (CSs) is modeled as a many-to-one matching game and the Stable Matching Algorithm (SMA) is proposed. For cooperative EV charging and discharging in parking pattern, the electricity exchange between charging EVs and discharging EVs in the same parking lot is formulated as a many-to-many matching model with ties, and we develop the Pareto Optimal Matching Algorithm (POMA). Simulation results indicates that the SMA can significantly improve the average system utility for EV charging in driving pattern, and the POMA can increase the amount of electricity offloaded from the grid which is helpful to enhance the reliability of the power grid.

Matching theory based travel plan aware charging algorithms in V2G smart grid networks

The frequency, time and places of charging have large impact on the Quality of Experience (QoE) of EV drivers. It is critical to design effective EV charging scheduling system to improve the QoE of EV drivers. In order to improve EV charging QoE and utilization of CSs, we develop an innovative travel plan aware charging scheduling scheme for moving EVs to be charged at Charging Stations (CS). In the design of the proposed charging scheduling scheme for moving EVs, the travel routes of EVs and the utility of CSs are taken into consideration. The assignment of EVs to CSs is modeled as a two-sided many-to-one matching game with the objective of maximizing the system utility which reflects the satisfactory degrees of EVs and the profits of CSs. A Stable Matching Algorithm (SMA) is proposed to seek stable matching between charging EVs and CSs. Furthermore, an improved Learning based On-LiNe scheduling Algorithm (LONA) is proposed to be executed by each CS in a distributed manner. The performance gain of the average system utility by the SMA is up to 38.2% comparing to the Random Charging Scheduling (RCS) algorithm, and 4.67% comparing to Only utility of Electric Vehicle Concerned (OEVC) scheme. The effectiveness of the proposed SMA and LONA is also demonstrated by simulations in terms of the satisfactory ratio of charging EVs and the the convergence speed of iteration.

Risk premiumin the global creditMarkets: 2006-2012

¿What have we learnt from the 2006-2012 crisis, including events such as the subprime crisis, the bankruptcy of Lehman Brothers or the European sovereign debt crisis, among others? It is usually assumed that in firms that have a CDS quotation, this CDS is the key factor in establishing the credit premiumrisk for a new financial asset. Thus, the CDS is a key element for any investor in taking relative value opportunities across a firm’s capital structure. In the first chapter we study the most relevant aspects of the microstructure of the CDS market in terms of pricing, to have a clear idea of how this market works. We consider that such an analysis is a necessary point for establishing a solid base for the rest of the chapters in order to carry out the different empirical studies we perform. In its document “Basel III: A global regulatory framework for more resilient banks and banking systems”, Basel sets the requirement of a capital charge for credit valuation adjustment (CVA) risk in the trading book and its methodology for the computation for the capital requirement. This regulatory requirement has added extra pressure for in-depth knowledge of the CDS market and this motivates the analysis performed in this thesis. The problem arises in estimating of the credit risk premium for those counterparties without a directly quoted CDS in the market. How can we estimate the credit spread for an issuer without CDS? In addition to this, given the high volatility period in the credit market in the last few years and, in particular, after the default of Lehman Brothers on 15 September 2008, we observe the presence of big outliers in the distribution of credit spread in the different combinations of rating, industry and region. After an exhaustive analysis of the results from the different models studied, we have reached the following conclusions. It is clear that hierarchical regression models fit the data much better than those of non-hierarchical regression. Furthermore,we generally prefer the median model (50%-quantile regression) to the mean model (standard OLS regression) due to its robustness when assigning the price to a new credit asset without spread,minimizing the “inversion problem”. Finally, an additional fundamental reason to prefer the median model is the typical "right skewness" distribution of CDS spreads...

Principios de la contratación estatal aplicables a los reglamentos especiales de contratación de la agencia nacional de hidrocarburos

El estatuto de contratación administrativa (Ley 80 de 1993 y Ley 1150 de 2007) por regla general regula todos los negocios jurídicos que surgen de la actividad de la Administración Pública, pero teniendo en cuenta las actividades que desarrollan algunas entidades del Estado esta regla tiende a presentar excepciones, como es el caso de aquellas Entidades que tienen por objeto la Exploración y Explotación de los Recursos Naturales renovables y no renovables. El principal actor del régimen excepcional de contratación para la exploración y explotación de hidrocarburos es la Agencia Nacional de Hidrocarburos (ANH), el cual cuenta con dos reglamentos de contratación especial para la asignación de áreas y de contratación misional, en donde por disposición legal debe dar aplicación a los principios de contratación contemplados en el estatuto General de la Contratación pública (Transparencia, economía, responsabilidad y el deber de selección objetiva), este trabajo de investigación procura realizar una mirada analítica a cada procedimiento para determinar con posterioridad el grado de acatamiento de la orden legal establecida en el artículo 76 de la Ley 80 de 1993 así como sus principales falencias

Interpretación Modesta de la Responsabilidad Moral: Lectura de Strawson desde el sentido histórico y situado de la humanidad

En esta monografía reseño la forma como Peter Strawson enmarca el debate de la responsabilidad moral en un lugar que denomino más cerca de lo humano. Considero que son las actitudes reactivas, propuestas por Peter Strawson, una pieza fundamental para entender qué es la responsabilidad moral. Esta perspectiva no está libre de contradictores, es por ese motivo que plantearé una interpretación de la idea de Strawson que tiene como objetivo responder algunas críticas que recaen sobre esta forma de conceptualizar las relaciones interpersonales. Construiré la defensa alrededor de la interpretación de la responsabilidad moral que entiende la asignación de la responsabilidad moral como un tipo de lenguaje que adquiere su significado en la medida que se usa. De manera análoga, planteo el interrogante de si es posible pensar en un sistema de responsabilidad moral que se justifica en la medida que se usa. Considero que esta idea tiene sentido con algo denominado la circularidad virtuosa. La pregunta que sale a la luz de inmediato es ¿cómo es posible usar un sistema de responsabilidad moral que se va justificando en la medida que se usa? En realidad, no solo es en la medida que se usa, sino también en el trascurso en el que los seres humanos se reconocen unos con otros y entablan ciertas prácticas. Para entender y justificar esta cuestión planteo una interpretación de la postura de Strawson que denomino “Interpretación Modesta de la Responsabilidad Moral”.
