Diseño y fabricación de un instrumento coaxial para cirugía laparoscópica.

[ES]En este trabajo se ha diseñado un producto secundario con una fijación extra en formato trocar para operaciones percutáneas dirigidas por sistemas de imagen. Este instrumento que hasta ahora era inexistente en el mercado actuará como túnel, permitiendo la introducción de agujas de radiofrecuencia y biopsia por su interior. La particularidad de este producto es el diseño del sistema de sujeción, que garantizará al cirujano que el punto a intervenir sea el mismo durante toda la operación. Este diseño se ha realizado después de hacer un estudio en profundidad de las alternativas existentes de los sistemas de fijación en el campo de la medicina oncológica y el sector industrial. Además se detalla el material de cada elemento del producto en base a la norma sanitaria correspondiente, también se explica el proceso más adecuado para la fabricación de dichos elementos y por último se realiza un cálculo sencillo del pandeo de la aguja, que garantice un uso óptimo del instrumento.

Social Security, Education, Retirement and Growth

In this paper we analyze the effects of social security policies in an unfunded, earnings-related social security system on the incentives to education investment and voluntary retirement, on growth and on income inequality. Growth is endogenously driven by human capital investment, individuals differ in their innate (learning) ability at birth, and the pension scheme includes a minimum pension. More skilled individuals spend more on education, minimum pensions reduce low skill individuals' incentives to invest in human capital, there is no monotonic relationship between per capita growth and income inequality.

The Black Box of Mutual Fund Fees

This paper re-examines the determinants of mutual fund fees paid by mutual fund shareholders for management costs and other expenses. There are two novelties with respect to previous studies. First, each type of fee is explained separately. Second, the paper employs a new dataset consisting of Spanish mutual funds, making it the second paper to study mutual fund fees outside the US market. Furthermore, the Spanish market has three interesting characteristics: (i) both distribution and management are highly dominated by banks and savings banks, which points towards potential conflicts of interest; (ii) Spanish mutual fund law imposes caps on all types of fees; and (iii) Spain ranks first in terms of average mutual fund fees among similar countries. We find significant differences in mutual fund fees not explained by the fund’s investment objective. For instance, management companies owned by banks and savings banks charge higher management fees and redemption fees to nonguaranteed funds. Also, investors in older non-guaranteed funds and non-guaranteed funds with a lower average investment are more likely to end up paying higher management fees. Moreover, there is clear evidence that some mutual funds enjoy better conditions from custodial institutions than others. In contrast to evidence from the US market, larger funds are not associated with lower fees, but with higher custody fees for guaranteed funds and higher redemption fees for both types of funds. Finally, fee-setting by mutual funds is not related to fund before-fee performance.

Population age structure and private consumption in Spain

In this paper we study the effect of population age distribution upon private consumption expenditure in Spain from 1964 to 1997 using aggregate data. We obtain four main results. First, changes in the population pyramid have substantial effects upon the behaviour of private consumption. Second, the pattern of the coefficients of the demographic variables is not consistent with the simplest version of the life cycle hypothesis. Third, we estimate the impact of the demographic transition upon consumption and find positive values associated with episodes in which the shares of groups of individuals with expenditure levels higher (lower) than the mean increased (decreased). Fourth, the results are robust to alternative specifications for the population age distribution.
