Optimal Minimum Wage in a Competitive Economy: an Alternative Modelling Approach

This paper analyzes whether a minimum wage can be an optimal redistribution policy when distorting taxes and lump-sum transfers are also available in a competitive economy. We build a static general equilibrium model with a Ramsey planner making decisions on taxes, transfers, and minimum wage levels. Workers are assumed to differ only in their productivity. We find that optimal redistribution may imply the use of a minimum wage. The key factor driving our results is the reaction of the demand for low skilled labor to the minimum wage law. Hence, an optimal minimum wage appears to be most likely when low skilled households are scarce, the complementarity between the two types of workers is large or the difference in productivity is small. The main contribution of the paper is a modelling approach that allows us to adopt analysis and solution techniques widely used in recent public finance research. Moreover, this modelling strategy is flexible enough to allow for potential extensions to include dynamics into the model.

Competitive Pressure and Job Interview Lying: A Game Theoretical Analysis

We consider a job contest in which candidates go through interviews (cheap talk) and are subject to reference checks. We show how competitive pressure - increasing the ratio of "good" to "bad" type candi- dates - can lead to a vast increase in lying and in some cases make bad hires more likely. As the number of candidates increases, it becomes harder to in- duce truth-telling. The interview stage becomes redundant if the candidates, a priori, know each others' type or the result of their own reference check. Finally, we show that the employer can bene t from committing not to reject all the applicants.

Competitive issue of money & abolition of central banks

The aim of this work is to analyze the main characteristics of the current financial system and to investigate the arising of critical voices with respect this system. In particular, we analyze some historical facts that have been important in the creation of this financial order. We analyze the new digital currency, known as Bitcoin, as the basic ingredient in the formation of a new alternative and decentralized international financial system. In 10 years Bitcoin has expanded its influence to many economic activities. We also analyzed briefly the classic liberal theory that criticizes the intervention of governments in the markets. Finally, we consider relevant the arising of a group of countries (BRICS) that may challenge the current system where the position of USA is privileged.

Estudio de caso de organización empresarial.: Liderazgo, motivación y comunicación interna en Iberdrola S.A.

El presente trabajo trata de analizar y explicar la relación entre el comportamiento de los individuos en las empresas y la consecución de los objetivos establecidos a través de la aplicación práctica de diferentes teorías de liderazgo y motivación en una empresa real como es Iberdrola. Debido a las dimensiones de la empresa y a la complejidad a la hora de obtener información relevante para el proyecto, centraremos nuestro análisis únicamente en el departamento de Compras y Seguros. Consideramos que las personas son el activo más valioso de las empresas ya que, al fin y al cabo, son el único factor diferenciador de las empresas, es el factor que puede distinguir entre una compañía competitiva de otra que no lo es. Por ello, creemos que es imprescindible analizar el comportamiento de los componentes de una empresa para identificar posibilidades de mejora, con el fin de alcanzar los objetivos establecidos. El proyecto tal y como hemos mencionado, principalmente se centra en el análisis del liderazgo y la motivación existente en el equipo de Compras y Seguros de Iberdrola S.A. Con los resultados obtenidos en el análisis se realizará una propuesta de valor con el fin de aportar diferentes alternativas que, acorde con algunas teorías organizacionales, puedan beneficiar a la empresa a la hora de conseguir sus diferentes metas en función de la situación en la que esté la empresa, las cualidades y comportamientos de todos sus componentes.

Effects of Small-Sided Games vs. Interval Training in Aerobic Fitness and Physical Enjoyment in Young Elite Soccer Players

The purpose of this study was to compare the effects of Small-Sided Games (SSG) vs. Interval Training (IT) in soccer training on aerobic fitness and physical enjoyment in youth elite soccer players during the last 8 weeks of the season. Seventeen U-16 male soccer players (age = 15.5 +/- 0.6 years, and 8.5 years of experience) of a Spanish First Division club academy were randomized to 2 different groups for 6 weeks: SSG group (n = 9) and IT group (n = 8). In addition to the usual technical and tactical sessions and competitive games, the SSG group performed 11 sessions with different SSGs, whereas the IT group performed the same number of sessions of IT. Players were tested before and after the 6-week training intervention with a continuous maximal multistage running field test and the counter movement jump test (CMJ). At the end of the study, players answered the physical activity enjoyment scale (PACES). During the study, heart rate (HR) and session perceived effort (sRPE) were assessed. SSGs were as effective as IT in maintaining the aerobic fitness in elite young soccer players during the last weeks of the season. Players in the SSG group declared a greater physical enjoyment than IT (P = 0.006; ES = 1.86 +/- 1.07). Coaches could use SSG training during the last weeks of the season as an option without fear of losing aerobic fitness while promoting high physical enjoyment.
