An empirical assessment of the Feltham-Ohlson models considering the sign of abnormal earnings

2006

Abstract This paper provides an empirical assessment of the Feltham-Ohlson models, distinguishing between firms with positive and negative abnormal earnings. Abnormal earnings persistence and conservatism parameters differ for these two groups; this implies different earnings prediction models and valuation functions for both profit-making and loss-making firms. The analysis refers to the period 1991-1999 and uses a sample of Spanish firms quoted on the Madrid S.E. The results suggest that our contextual approach is more useful than the non-contextual one to predict future abnormal earnings and explain current prices. Although the Ohlson (1995) model is accurate in forecasting future abnorm…

The Investment on Capital Market: From Target Price Valuation Models to Investor Final Decision

2018

The investments on capital market are more attractive nowadays considering the short-term potential earnings that this particular market can offer but also the opportunities generated by the new entry companies. The aim of the paper is to present different valuation models of share in order to identify/calculate a target price, on one hand, and to emphasize the impact of both internal and external information on price per share, on the other hand. The target price is an important instrument that drives, alongside with industry, financial, and risk analysis, the investment decision to buy, to hold, and to sell. The key issues in determining target price are equity analysis, cash flow forecas…

Evaluating the Regional Impact of a New Road on Tourism

2004

Ferri J. (2004) Evaluating the regional impact of a new road on tourism, Reg. Studies 38, 409–418. The aim of this work is to establish whether the opening of a motorway that extends along the east coast of Spain has significantly contributed to expanding hotel tourism in the Valencia region. Some of the most important tourist destinations in Spain, both domestic and international, are located in this region, such as Benidorm, Peniscola and Gandia. The A-7 motorway, also part of the E-15 road network, is not only a faster and safer means of road communication for tourists but also provides a new gate to Europe, connecting with other motorways. Using monthly data on nights spent in hotels by…

A qui profite le tutorat mis en place dans le premier cycle universitaire ?

2000

International audience; Cet article présente les résultats d'une recherche portant sur l'évaluation du tutorat d'accompagnement mis en place en première année de premier cycle universitaire à l'Université de Bourgogne. Ce dispositif de soutien destiné aux étudiants en difficulté est basé sur les principes du volontariat et du libre accès. Les résultats principaux de cette évaluation font apparaître un effet positif du dispositif, bien que les plus concernés par ces actions de soutien ne soient cependant pas les plus présents ni les plus assidus.

L'évaluation des dispositifs éducatifs et de formation

2005

05085; L'objectif principal des évaluations nationales est de permettre l'observation des compétences des élèves en début de cycle, elles fournissent aux enseignants des repères exploitables quant aux types d'erreurs fréquemment produites par les élèves au cours de leur apprentissage. Même si la dimension diagnostique reste prioritaire, ces évaluations peuvent également constituer un outil de pilotage au niveau national et local, mais des précautions doivent être prises en vue d'une interprétation correcte des résultats. Deux faiblesses principales caractérisent les épreuves nationales : la première porte sur l'échelle de mesure du niveau de connaissances scolaires, la seconde sur la défini…

Evolution et structure des compétences des élèves à l'école élémentaire et au collège : une analyse empirique des évaluations nationales

2006

Le rapport est structuré en plusieurs parties. Le premire chapitre propose l'analyse détaillée des résultats des élèves aux évaluations de CE2. Le second chapitre traite de deux points : l'identification de compétences sur une base empirique (analyse en variables latentes) et l'analyse des relations entre ces compétences. Le troisième chapitre s'intéresse à la mesure de l'évolution des compétences au cours du cycle III et propose également une mise en relation entre les compétences scolaires et les capacités cognitives des élèves. Le quatrième chapitre se centre sur l'analyse des résultats des élèves aux évaluations de fin de 5ème.

Microbial toxicity and impacts on soil enzyme activities of pesticides used in potato cultivation

2009

In the conventional cultivation of potatoes, weed control and the control of potato late blight caused by Phytophthora infestans are carried out by the application of herbicides and fungicides. We investigated the impacts of the herbicides metribuzin and linuron and the fungicide fluazinam on soil microbiota in microcosms, in mesocosms and in the field. The toxicity of each pesticide in solution was assessed using the luminescent bacteria test and in soil by a solid phase modification. In microcosm tests, the microbial activity and biomass were estimated by measuring several soil enzyme activities together with soil ATP content. In the mesocosm tests, the separate addition of each pesticide…

Agricultural landscapes and biodiversity conservation: a case study in Sicily (Italy)

2015

The diversity of life is made up not only of the diversity of plants and animal species, habitats and ecosystems, but also of the diversity of human cultures. These diversities interact with one another in complex ways and express the mutual adaptation between humans and the environment at local level. Sicilian traditional agro-ecosystems, due to the history of the territory and the resulting social and economic context, are configured in a heterogeneous mosaic rich in residual features of environmental value, which enhance the connectivity of the ecological network and support a high proportion of species that are rare or of conservation concern. As a case study we analyzed the characteris…

Rail freight transport and demand requirements : an analysis of attribute cut-offs through a stated preference experiment

2014

This paper analyses the choice between road and rail in Spain where rail market share for freight is still residual. Discrete choice models are estimated with data obtained through a two-phase fieldwork, thus allowing us to carry out a stated preference efficient design for each interviewee. We analyse the existence of attribute cut-offs and the presence of a segment of the population with a zero value of frequency. Our results show that ignoring the existence of cut-offs and segments of the population with polarised valuations can lead to erroneous conclusions in terms of the possibilities of rail for absorbing significant quota.
