Mercados Financieros: ¿eficientes o irracionales?

[EN]When we talk about financial markets, we usually talk about falls or rises occurring in them, the earnings of enterprises and their strategic plans... Throughout history a lot of theories and studies have been carried out on them, being the Theory of Efficiency the most one accepted nowadays. But in all of this, there is a great forgotten that is not usually taken into account and that is an important factor, if not the most, in the markets, which is none other than humans. The work is based on the confrontation, practical and theoretical, between the Theory of Efficiency on financial markets and the Theory of Behavioral Finance, with the objective of generating samples in order to see if markets are efficient or irrational. After all, decisions of buying or selling, to acquire a fund or bonds are held by humans. Therefore, in the effort to understand financial markets, understanding human psychology is something essential. Inglés

Financial Futures Markets and Their Impact on the Real Economy in Middle and Low Income Countries

This project analyses the influence of the futures market on middle and low income countries. In it, I attempt to show that investments made by large investment funds in this market, as well as by certain pension plans, bring major consequences whose effects are more evident in less developed countries. The cornerstones of the work are as follows; to attempt to see the existing relationship between the commodity futures market and its underlying assets; analysing products such as wheat, rice and corn in-depth, because these are the most basic foodstuffs at a global level; to determine how an increase in trading in these markets can affect the lives of people in the poorest countries; to analyse investor concern regarding the consequences that their investments may have. Throughout the project we will see how large speculators use production forecasting models to determine the shortage of a commodity in order to take a position in the futures market to profit from it. In addition we will see how an increase in trading in this market causes an increase in the price of the underlying asset in the spot market. As for investor concern, I can say it is negligible, but the idea of running pension plans or investment funds that follow some social criteria has been welcomed by those interviewed, which makes me think that different legislation is possible. This legislation will only come into existence if it is demanded by the people. A fact that now becomes complicated because without a minimum financial basis, they cannot even know how the large investment funds trade with hunger in the world. The day when most people understand how large speculators profit from famine will be the day to put pressure on governments to begin to put limits on speculation. This makes financial awareness necessary in order to achieve a curb in excessive speculation.

The Environmental, Social, Governance, and Financial Performance Effects on Companies that Adopt the United Nations Global Compact

This paper aims to investigate companies' environmental, social, governance (ESG), and financial implications of their commitment to the United Nations Global Compact (UNGC). The focus is placed on companies operating in the three countries with the highest number of UNGC participants: Spain, France, and Japan. The results clearly reveal that adoption of the UNGC often requires an organizational change that fosters stakeholder engagement, ultimately resulting in improvements in companies' ESG performance. Additionally, the results reveal that ESG performance has a significant impact on financial performance for companies that adopted the principles of the UNGC. These findings provide both non-financial and financial incentives to companies to commit to this voluntary corporate social responsibility (CSR) initiative, which will have important implications on companies' strategic management policies that aim to foster sustainable businesses and community development. Finally, the linkages between the UNGC-committed companies' ESG and financial performance may be influenced by geographical spread, mainly due to the appearance of differences in the institutional, societal, and cultural settings.

Relación entre la globalización y la internacionalización financiera: el caso de las empresas vascas

[ES] Cada vez es mayor el número de empresas que optan por acudir a mercados financieros exteriores, tanto al objeto de obtener financiación en mejores condiciones, como para realizar inversiones más atractivas que las disponibles dentro de las fronteras nacionales. La decisión de internacionalizar el área financiera de la empresa puede ser el resultado de una estrategia específica orientada al aprovechamiento de las oportunidades que ofrece el proceso de globalización financiera, que se está desarrollando de forma vertiginosa los últimos años.

Income Taxation and Growth in an OLG Economy: Does Aggregate Uncertainty Play any Role?

We analyze the effects of capital income taxation on long-run growth in a stochastic, two-period overlapping generations economy. Endogenous growth is driven by a positive externality of physical capital in the production sector that makes firms exhibit an aggregate technology in equilibrium. We distinguish between capital income and labor income, and between attitudes towards risk and intertemporal substitution of consumption. We show necessary and sufficient conditions such that i) increments in the capital income taxation lead to higher equilibrium growth rates, and ii) the effect of changes in the capital income tax rate on the equilibrium growth may be of opposite signs in stochastic and in deterministic economies. Such a sign reversal is shown to be more likely depending on i) how the intertemporal elasticity of substitution compares to one, and ii) the size of second- period labor supply. Numerical simulations show that for reasonable values of the intertemporal elasticity of substitution, a sign reversal shows up only for implausibly high values of the second- period’s labor supply. The conclusion is that deterministic OLG economies are a good approximation of the effect of taxes on the equilibrium growth rate as in Smith (1996).

Asset pricing and systematic liquidity risk: an empirical investigation of the Spanish stock market

Systematic liquidity shocks should affect the optimal behavior of agents in financial markets. Indeed, fluctuations in various measures of liquidity are significantly correlated across common stocks. Accordingly, this paper empirically analyzes whether Spanish average returns vary cross-sectionally with betas estimated relative to two competing liquidity risk factors. The first one, proposed by Pastor and Stambaugh (2002), is associated with the strength of volume-related return reversals. Our marketwide liquidity factor is defined as the difference between returns highly sensitive to changes in the relative bid-ask spread and returns with low sensitivities to those changes. Our empirical results show that neither of these proxies for systematic liquidity risk seems to be priced in the Spanish stock market. Further international evidence is deserved.

Balance de la política fiscal desarrollada en España en época de crisis. ¿Por qué elegir el camino contractivo?

The use of a contractive fiscal policy in times of crisis and austerity can lead to so many different opinion streams which can be, at the same time, very opposite with each other. The high budget deficit in some economies has forced the eurozone to implement austerity policies, meaning that the debate is now more alive than ever. Therefore, the aim of this paper is to analyze the effects of the implementation of a contractive policy during a crisis considering the case of Spain. The positive effects in financial markets were noticed due to the decrease of the risk premium and the payment of interests, and also thanks to the increase of trust towards Spain. This way, the reduction of the Spanish deficit was remarkable but in any case there is still a long path until reaching the limit of 3% of the GDP. Also, in the short run it is possible to see that the consolidation had contractive effects in the economic activity but, in the long run, the debate is among the defenders of the fact that austerity is followed by a growing period and the ones opposing to it due to the drowning effect produced by it.
