El efecto del anuncio de beneficios cuando cotizan opciones: un estudio conjunto del mercado de contado y el mercado de opciones

2015

ResumenEl objetivo del trabajo es comprobar, para los mercados de valores españoles, si el comportamiento de los precios incorporando la información revelada por el anuncio de beneficios trimestrales, es más eficiente en aquellas empresas en las cuales se negocian opciones sobre sus acciones. Utilizando la tradicional metodología del suceso y la comparación de funciones de distribución, obtenemos que para las empresas con opciones, la información se incorpora antes. Además, verificamos que hay un comportamiento anormal en el mercado de opciones que viene explicado por la información que contiene el beneficio. Los resultados obtenidos soportan la mejora de la eficiencia del mercado de contad…

SOCIO-CULTURAL FACTORS AND INTERNATIONAL COMPETITIVENESS

2015

Socio-cultural factors – shared values, norms and attitudes are significant, but less acknowledged sources of international competitiveness. Previous studies have found socio-cultural factors positively affecting various aspects of international competitiveness – entrepreneurship, innovation, productivity and international cooperation. These factors are more sustainable and less affected by external environment changes in comparison with the traditional factors. Socio-cultural factors provide an opportunity to develop competitiveness strategies based on unique advantages. This research aims to explore the impact of socio-cultural factors on international competiveness in small, open economi…

Conflicting vocational identities and careers in the sector of tourism

2004

This article investigates the formation of vocational identities of workers in the sector of tourism in the Czech Republic, Greece and Spain. Major challenges and conflicts shape the sector of tourism as a particular labour space. Emerging issues relate to the need for diversifying the offer of services to face seasonality, strategies of entrepreneurial merging and demands for mobility and flexibility of the workforce. For the individual worker, a complex combination of related factors lead to tensions and contradictions, particularly in terms of changes in work organization, flexibility and how vocational identities of workers are shaped. An active policy for social dialogue and the improv…

The Effects of a Structured Curriculum on Preschool Effectiveness: A Field Experiment

2021

Abstract: This study tests an intervention that introduces a structured curriculum for five-year-olds into the universal preschool context of Norway, where the business as usual is an unstructured curriculum. We conduct a field experiment with 691 five-year-olds in 71 preschools and measure treatment impacts on children’s development in mathematics, language, and executive functioning. The nine-month intervention has effects on child development at post-intervention and the effects persist one year following the end of the treatment. The effects are mainly driven by the preschools identified as low-quality at baseline, indicating that a structured curriculum can reduce inequality in early c…

Testing for non-linearity in an artificial financial market: a recurrence quantification approach

2004

Abstract In this paper, earlier work on testing for non-linear dynamics on realizations from an artificial financial market is extended in two ways. On the one hand, Hinich’s bispectral test and White’s neural network test are computed. On the other hand, a recently developed methodology to test for hidden structures in data, inherited from Physics, is successfully applied on the realizations of the artificial market. Results among alternative tests are compared.

Demand for life annuities from married couples with a bequest motive

2006

The aim of this paper is to explain the ‘annuities puzzle’ in greater depth by introducing the bequest motive. It will try to determine whether this motive really is a relevant feature influencing the demand for life annuities from married couples. With this aim in mind, we develop an optimization model of the utility provided by purchasing a life annuity with contingent survivor benefit or a joint survivor life annuity. Our model is based on that first put forward by Brown and Poterba (2000), to which we have added elements from other models, such as Friedman and Warshawsky's (1990) and Vidal and Lejárraga's (2004), which include the bequest motive. This will enable us to calculate the ann…

Has pharmaceutical research become more scientific?

1996

Pharmaceutical research continues to be highly empirical, despite some recent writings arguing that it has become more scientific. Contrary to a study asserting that Mevacor, Tagamet, and Capoten demonstrate the success of targeted research, these drugs were discovered only after many years of following leads. Two hypotheses implied by the proposition that pharmaceutical research has become more scientific are tested. The first hypothesis is that the uncertainty of research has fallen. The second is that the number of publications by scientists in the industry has increased. Both are rejected.

Bazaar economics

2015

Competitive Equilibrium theory has been a widely accepted and extensively used cornerstone in economics for over a century. Here, we suggest a complementary model—motivated by the haggling in a bazaar—that offers a useful, first-principle account of market behavior that better accounts for the observed outcomes in forty market experiments. The Bazaar model uses simple stochastic processes to drive the matching of traders and the determination of price. We show that as agents become more impatient, the system tends toward more Competitive-Equilibrium-like outcomes.
