The measurement of rank mobility
2009
Abstract In this paper we investigate the problem of measuring social mobility when the social status of individuals is given by their rank. In order to sensibly represent the rank mobility of subgroups within a given society, we address the problem in terms of partial permutation matrices which include standard (“global”) matrices as a special case. We first provide a characterization of a partial ordering on partial matrices which, in the standard case of global matrices, coincides with the well-known “concordance” ordering. We then provide a characterization of an index of rank mobility based on partial matrices and show that, in the standard case of comparing global matrices, it is equi…
The impact of social capital and collaborative knowledge creation on e-business proactiveness and organizational agility in responding to the COVID-1…
2020
The purpose of this study is to explore the role of social capital and collaborative knowledge creation in achieving e-business proactiveness in responding to the COVID-19 crisis An online survey was used to collect data from industries that had to continue working during the crisis, such as the pharmaceutical and cleaning materials sectors The sample consisted of 198 managers The findings show that social capital and collaborative knowledge creation have a significant role in achieving e-business proactiveness in responding to the pandemic The results also show the positive impact of collaborative knowledge creation and e-business proactiveness on organizational agility during the crisis T…
Technology and Labor Regulations: Theory and Evidence
2015
This paper shows that different labor market policies can lead to differences in technology across sectors in a model of labor saving technologies. Labor market regulations reduce the skill premium and as a result, if technologies are labor saving, countries with more stringent labor regulation, which bind more for low skilled workers, become less technolog- ically advanced in their high skill sectors, but more technologically advanced in their low skill sectors. We then present data on capital-output ratios, on estimated productivity levels and on patent creation, which tend to support the predictions of our model.
Redistribution, selection, and trade
2017
Abstract This paper examines the distributional effects of international trade in a general equilibrium model with heterogeneous agents and a welfare state redistributing income. The redistribution scheme is financed by a progressive income tax and gives the same absolute transfer to all individuals. Ceteris paribus, international trade leads to an increase in income per capita but also to higher income inequality on two fronts. Inter-group inequality between managers and workers increases, and intra-group inequality within the group of managers goes up as well. We show that for a given tax rate, there is an endogenous increase in the size of the welfare state that works against the increas…
Empirical Approaches Upon Pension Systems in Central and Eastern European Countries. Triangle Assessment: Free Movement of People, Labor Market and P…
2020
Abstract Nowadays, around the world, it can be noticed an important trend towards the pension system reforms. The creation of the European fiscal space, the effects of globalization and the movement of the labour force are important vectors towards creating a new type of social economy. The labour force is constantly moving around the countries that gathered important amounts of capital, especially in industrialized countries. Moreover, the lower levels of the birth rate combined with the increasing level of death rate unbalance the labour market. The entire European continent undergoes a demographical transition period, highlighted by aging and intensive migration. This phenomenon is regis…
Patents, technological inputs and spillovers among regions
2009
This paper analyses the importance of different technological inputs (R&D and human capital) and different spillovers in explaining the differences in patenting among Spanish regions in the period 1986-2003. The analysis is based on the estimation of a knowledge production function. A region¿s own R&D activities and human capital are observed to have a positive significant effect on innovation output, measured by the number of patents. R&D spillovers weighted by the distance and the volume of trade flows between regions cause positive effects on a region¿s patents. However, distance matters more than the intensity of trade flows and the R&D spillover effects between regions are bounded: spi…
From the great depression to bretton woods: Jacob Viner and international monetary stabilization (1930-1945)
2009
This paper examines Jacob Viner's contribution to the debate and the policy decision-making concerning international monetary policy from the Great Depression to the Bretton Woods agreements. An outstanding member of the so-called 'early Chicago School of Political Economy', Viner was actively engaged in the debate over the causes and cures of the Depression, emphasizing the important role international economic problems played in producing its onset and in reinforcing its duration. During the 1930s Viner was an outspoken supporter of international monetary cooperation, set up to secure exchange rates stability, which he regarded as a paramount factor in restoring business confidence and fo…
Sirenomelia, case report and review of the literature.
2020
We present a case of sirenomelia diagnosed in the first trimester of pregnancy. The ultrasound examination showed fused lower extremities and an anechoic structure in the lower abdomen that is clue in the early diagnosis. The postmortem study showed the existence of a single umbilical artery (vitelline artery), with an origin in the abdominal aorta. This finding not only explained the presence of a vascular steal with subsequent underdeveloped of pelvic organs, but also differentiated this condition from caudal regression syndrome.
La propuesta sobre educación de la comisión para el estudio de los problemas españoles (1945)
2019
En este artículo se analiza y transcribe el texto redactado por un grupo de destacados profesores y pedagogos españoles exiliados, con especial atención a su contextualización. El grupo integraba la ponencia sobre educación de la Comisión de estudio de los problemas españoles, impulsada por la Unión de Profesores Españoles en el Extranjero. El documento final fue publicado en 1945 en la ciudad de México D.F.: en los Talleres tipográficos de B. Costa Amic, y ocupa 23 páginas. Se trata de un auténtico programa de actuación a llevar a cabo tras la restauración de la República en España, que en esas fechas tras finalizar la guerra en Europa, se pensaba cercana. A group of Spanish leading teache…
