Causalities between CO2, electricity, and other energy variables during phase I and phase II of the EU ETS
2010
The topic of this article is the analysis of the interplay between daily carbon, electricity and gas price data with the European Union Emission Trading System (EU ETS) for CO2 emissions. In a first step we have performed Granger causality tests for Phase I of the EU ETS (January 2005 until December 2007) and the first year of Phase II of the EU ETS (2008). The analysis includes both spot and forward markets—given the close interactions between the two sets of markets. The results show that during Phase I coal and gas prices, through the clean dark and spark spread, impacted CO2 futures prices, which in return Granger caused electricity prices. During the first year of the Phase II, the sho…
The term structure of volatility predictability
2020
Volatility forecasting is crucial for portfolio management, risk management, and pricing of derivative securities. Still, little is known about the accuracy of volatility forecasts and the horizon of volatility predictability. This paper aims to fill these gaps in the literature. We begin this paper by introducing the notions of the spot and forward predicted volatilities and propose to describe the term structure of volatility predictability by the spot and forward forecast accuracy curves. Then we perform a comprehensive study on the term structure of volatility predictability in the stock and foreign exchange markets. Our results quantify the volatility forecast accuracy across horizons …
Measuring the market power in the ceramic tile industry: An international comparison
2004
This paper measures the degree of competition faced by Spanish and Italian exporters of ceramic tiles in several European Union member states. The results indicate that Spanish producers have a substantial market power while Italian exporters face a high degree of competition. This finding is consistent with the significant gain (loss) in the world production and export shares that Spanish (Italian) producers experienced during the 1990s. The results are also consistent with accounting data. Furthermore, comparisons in the extent of market power across source countries and European destination markets reveal that most variation in the data is related to the source country. JEL no. F12, F14,…
Website quality and internal business factors: An empirical investigation in the Italian wine industry
2016
Purpose The purpose of this paper is dual. The first is to assess the quality of websites of Italian wineries, using the Web Assessment Index (WAI), and compare e-commerce and e-marketing websites. The second is to verify the existence of a relationship between the website quality and business revenue, on one hand, and the characteristics of managers, on the other. Design/methodology/approach A two-step survey was carried out to respond to the aims of the study. First, a sample of wineries was contacted to capture information on both the wineries and managerial characteristics. On the basis of the observed data, a second step of the analysis was performed taking into consideration 84 winer…

Tween Girls' Perception of Gender Roles and Gender Identities
2011
PurposeThe present study aims to examine girls' perception of gender roles and gender identities in Hong Kong.Design/methodology/approachA total of 16 girls aged 10 to 12 were asked to take pictures from the media that could illustrate “what girls or women should or should not be; and what girls or women should or should not do”. Qualitative interviews were conducted.FindingsAnalysis of interviews and images captured found that tween girls' perceived gender roles for females were based on a mixture of traditional and contemporary role models. Girls in Hong Kong demonstrated conservatism in sexuality. Sexy outlook and pre‐marital sexual relations were considered inappropriate. Tween girls sh…
Diversity of the selected elements of agricultural potential in the European Union countries
2020
Agricultural importance in determining the directions of respective regions results from its production potential. The agricultural potential of a given country is determined by natural resources, ways of using them, natural conditions, workforce resources, technical resources and basic economic conditions. In this paper, only income and rural population are taken under consideration to describe the agricultural potential. Currently, European Union countries are functioning under the assumptions of the Common Agricultural Policy, assuming, among other things, increasing agricultural productivity, ensuring an adequate standard of living for the rural population and stabilising markets. The E…
Determinants of individual tourist expenditure as a network: Empirical findings from Uruguay
2014
Abstract This paper introduces the use of graphical models for assessing the determinants of individual tourist spending. These models have the advantage of synthesizing and visualizing the relationships occurring within large sets of random variables, through an easy to interpret output. To this end, individual data from a large official survey of international tourists in Uruguay are used. Symmetric conditional independence structures are first investigated. Then subgraphs of each expenditure item's neighbourhood are extracted in order to assess the impact of main effects and interactions through proportional ordinal logistic regression. Results highlight the marginal role of socio-demogr…
Everyone’s in, on the game: financial crime and the organization of sporting events. Looking for a “virtuous” model
2020
PurposeThis study aims at investigating the phenomenon of financial crime with specific reference to the organization of major sporting events. In particular, in the light of the existing international regulatory framework and recent cases, the study highlights how the adoption of a “virtuous model” – from the point of view of transparency and legality – fully responds to the needs not only of the sports system itself but, also, and above all, of the entire international community.Design/methodology/approachThe paper combines deductive and inductive approaches in addition to consulting and analyzing the principal official reports on the matter, the state of the art, scholarly studies and so…
On the Stability of Stablecoins
2021
This paper investigates the volatility processes of stablecoins and their potential stochastic interdependencies with Bitcoin volatility. We employ a novel approach to choose the optimal combination for the power law exponent and the minimum value for the volatilities bending the power law. Our results indicate that Bitcoin volatility is well-behaved in a statistical sense with a finite theoretical variance. Surprisingly, the volatilities of stablecoins are statistically unstable and contemporaneously respond to Bitcoin volatility. Also, whereas the volatilities of stablecoins are not Granger-causal for Bitcoin volatility, lagged Bitcoin volatility exhibits Granger-causal effects on the vol…
