Histoire et évolution des appellations d'origine françaises
2019
During the 20th century, wine appellations of origin have largely developed to represent a significant part of the wine production of some countries, especially in Europe. The globalization of the production, trade and consumption of wine is a major fact of the 21st century economy. The question of appellations of origin and more generally geographical indications must be asked: Is it a survival 100 years after the first law on appellations of origin was adopted in France? Historical knowledge makes it possible to understand how law, both national and international, has been marked by major developments in this area. Regulations on the origin of products have undergone significant changes o…
Taxation in Emerging Market and Middle-Income Economies: Similarities and Differences Between Countries from Europe and Central Asia
2018
The studies and the research from specialty literature demonstrate that a free-open policy and an efficient governance of the economy are the basic pillars for economic and social growth, taxation having an essential role in the life of any nation. A fiscal system based on horizontal and vertical equity, stability, predictability, and efficiency contributes significantly to the sustainability of public finances. Based on these considerations, through this article, we will highlight the main similarities and differences in the field of taxation at the level of countries that are included in the emerging market and middle-income economies category from Europe and Central Asia, to identify bes…
The Risk-Relevance of Accounting Data: Evidence from the Spanish Stock Market
2006
This paper analyses the relevance of accounting fundamentals to inform about equity risk as measured by the cost of equity capital. Assuming the latter is a summary measure of how investors make decisions regarding the allocation of resources, the strength of the association between the cost of capital and the accounting-based measures of risk indicates how important these measures are for market participants when making economic decisions. To infer the cost of equity capital, we use the O'Hanlon and Steele's method, which is based on the residual income valuation model. Moreover, we use the insights from this model to provide a theoretical underpinning for the choice of the accounting vari…
Equity Issues in the Spanish Stock Market: Windows of Opportunity, Earnings Management or Market Timing?
2005
We investigate whether the market sentiment and/or the specific operating performance of firms that conducted an equity issue on the Spanish stock market during the period 1993-2000 are related to the long-run stock-return underperformance in the year following the issue of small and medium firms. Our results reveal that equity issues were conducted by large firms just when the market showed optimistic expectations towards large firms in general. This overoptimism towards large issue firms was related to the 1990s technology boom in the case of initial public offerings (IPO), but we detect earnings management by large firms that conducted a seasoned equity offering (SEO). In this context, s…
Volatility transmission patterns and terrorist attacks
2009
The objective of this study is to analyze volatility transmission between the US and Eurozone stock markets considering the effects of the September 11, March 11 and July 7 financial crises. In order to do this, we use a multivariate GARCH model and take into account the asymmetric volatility phenomenon, the non-synchronous trading problem and the crises themselves. Moreover, a graphical analysis of the Asymmetric Volatility Impulse-Response Functions (AVIRF) is introduced, which takes into consideration the crisis effect. Results suggest that there is bidirectional and asymmetric volatility transmission and show the different impact that terrorist attacks had on both markets. El objetivo d…
Testing for financial contagion between developed and emerging markets during the 1997 East Asian crisis
2005
In this paper we examine whether during the 1997 East Asian crisis there was any contagion from the four largest economies in the region (Thailand, Indonesia, Korea and Malaysia) to a number of developed countries (Japan, UK, Germany and France). Following Forbes and Rigobon, we test for contagion as a significant positive shift in the correlation between asset returns, taking into account heteroscedasticity and endogeneity bias. Furthermore, we improve on earlier empirical studies by carrying out a full sample test of the stability of the system that relies on more plausible (over) identifying restrictions. The estimation results provide some evidence of contagion, in particular from Japan…
A computational proposal for a robust estimation of the Pareto tail index: An application to emerging markets
2022
Abstract In this work, we backtest and compare, under the VaR risk measure, the fitting performances of three classes of density distributions (Gaussian, Stable and Pareto) with respect to three different types of emerging markets: Egypt, Qatar and Mexico. We also propose a new technique for the estimation of the Pareto tail index by means of the Threshold Accepting (TAVaR) and the Hybrid Particle Swarm Optimization algorithm (H-PSOVaR). Furthermore, we test the accuracy and robustness of our estimates demonstrating the effectiveness of the proposed approach.
Breaking the barriers of animosity: innovation in business models as a positioning strategy
2021
Consumer animosity is often studied in the large economies of the world, in order to explain the negative feelings generated by an individual towards another country and its products, due to various political, economic and social conflicts. This study presents three specific developments in this field. First, to demonstrate how companies in the retail sector have been able to develop innovations in their business models through their shops and virtual channels, which generate a positive positioning in the mind of the consumer, capable of minimizing animosity towards them. In this way it is shown that a consumer can have strong feelings of patriotism, animosity and ethnocentrism, and yet a p…
Media Tone Goes Viral: Global Evidence from the Currency Market
2020
Using several million news and social media articles related to currencies, we examine the role of media tone in predicting the exchange rate returns of 12 developed and 24 emerging markets from 1998 to 2016. The text-based currency Media tone is a strong positive predictor of currency excess returns beyond fundamentals of one to three months ahead and six months cumulatively, with the average in-sample and out-of-sample R^2s of 4.45% and 9.03% in the US. The one-month predictability is observed in four other developed markets and 18 emerging market currencies, with the latter showing a stronger pattern. This predictability encompasses previous month currency returns, currency factors, macr…
Wear modelling in mild steel orthogonal cutting when using uncoated carbide tools
2007
Abstract Wear prediction in machining has been recently studied by FEM although the use of numerical methods for such applications is still a very challenging research issue. In fact, wear phenomenon involves many aspects related to process mechanics which require a very accurate modelling. In other words, only a very punctual code set-up can help the researchers in order to obtain consistent results in FE analysis. The high relative velocity between chip and tool requires effective material models as well as friction modelling at the interface. Moreover the prediction of temperature distribution is another critical task; in the paper some different procedures are discussed. Subsequently a …
