Value for money in energy efficiency retrofits in Ireland: grant provider and grant recipients

The Sustainable Energy Authority of Ireland (SEAI) administers the Better Energy Homes scheme to provide a financial incentive for home owners to engage in energy efficiency retrofits. This study analyses data from the scheme and Building Energy Rating data for participants to the scheme to examine the value for money achieved by households. In addition, this research identifies which retrofit combinations provide greatest value for money, in terms of energy efficiency gains, for the grant provider. We utilize an error-in-variables approach to model the variation in benefits accruing to households of varying characteristics. We find that household and grant provider surplus can be maximized in the short term by retrofitting less energy efficient and larger homes, timber or steel frame homes and houses rather and apartments. The types of retrofits leading to the greatest surplus for both household and grant provider include cavity wall insulation paired with either a boiler with heating controls or heating controls only retrofit.     

Do the EU countries import at the same price? The case of coffee

The establishment of the Economic and Monetary Union was expected to determine price convergence in the market of the European Union, leading to the equilibrium theorized by the law of one price. This article investigates prices convergence in the coffee market among European importers. Coffee is not only a tradable and traded good, but also one of the most valuable traded commodities. We account for different qualities of coffee in a hedonic regression model, which isolate and remove the effects of factors that might affect price dispersion. Adjusted import prices result to be significantly different between European Member States, and do not support the hypothesis of a deepening European market integration.     

The Success Factors of Food Events: The Case Study of Umbrian Extra Virgin Olive Oil

Gastronomic events are an important part of the “Made in Italy” and a vital tool for rural development. The aim of the study is to identify the complexity of the factors that determine the success of a food event. The authors, after state-of-the-art analysis of the event marketing, formulate the hypothesis of a causal model and form a data collection during the “open oil mills” in the Umbria region. Through in-depth interviews the participants were asked to express themselves about the importance and interest attributed to some aspects directly related to the theme of the event, and finally to indicate the degree of satisfaction and the likelihood of some of their future behavior. Statistical analysis based on structural equation models allowed the authors to highlight which aspects are significant in order to confirm the assumptions made. Results provide guidance for management decisions and organization of food and wine.     

SOCIAL COOPERATIVES IN ITALY: ECONOMIC ANTECEDENTS AND REGIONAL DISTRIBUTION

Social cooperatives represent the most notable form of non‐profit organizations operating in Italy in the social services field, the birth and development of which has been strongly linked to, and conditioned by, the needs and resources of territories and communities. This paper intends to demonstrate how certain socio‐economic factors, recognized in economic literature as antecedents of the development of social enterprises, may account for the spread of social cooperatives in different Italian regions. Furthermore, the research results demonstrate an inter‐regional differentiation of the shape social cooperation has entered into in Italy.     

External Imbalances and Fiscal Fragility in the Euro Area

This paper presents two views of the European sovereign debt crisis. The first is that countries in the South of the Eurozone were fiscally irresponsible and failed to implement pro-competitive supply side policies. The second view holds that the crisis reflects a deep divide between the external surpluses of the North and external deficits of the South. Basic stylized facts cast doubt on the explanation based on the first thesis alone. A relatively simple model shows how poor fundamentals can create a debt problem independently of fiscal responsibility. The empirical analysis of the determinants of government bond yield spreads relative to Germany suggests that both views in fact provide useful insights into the roots of the current sovereign crisis. However, differences in growth and competitiveness and capital flows between North and South have assumed a much more dominant role since the onset of the global crisis.     

NEW ORGANIZATIONAL MODELS IN EUROPEAN LOCAL PUBLIC TRANSPORT: FROM MYTH TO REALITY*

ABSTRACT: The Europeanization of public services is frequently considered to have created pressure for Member States to progressively converge towards a new dominant organizational model, based on deregulation, de‐integration and privatization. However, while in some sectors European directives played a crucial role in boosting a common evolutionary path, in other cases, mainly related to local public services, this influence remained feeble and more uncertain. The empirical insight on EU Local Public Transport Services carried out in this paper aims at investigating if and to what extent this new dominant paradigm actually emerges, or if and to what extent more fragmented and heterogeneous outcomes prevail. The main outcome is that the public role in Local Public Transport is still widespread and that a major theoretical and analytical focus should be directed to the ability of the principal‐competent public administration to play its role in an effective and sound manner, while often too much attention is paid to the characteristics of the agent‐operator (public‐private, big or small, foreign or national, etc.).     

A Market and Spatial Perspective of Health Tourism Destinations: The Hungarian Experience

Since health tourism is one of the most popular and most dynamically developing products of modern tourism, this paper aims at studying the characteristic features of health tourism destinations from a regional and spatial perspective. Accordingly, the authors would like to introduce a new approach of spatial and product analysis of tourism where the market and spatial relations and relevance of health tourism were analysed through the example of Hungary. Although the classic medical tourism centres were established on natural medical water basis, by today, due to product diversification, continuous innovation and the involvement of medical services into health tourism, the geographical embeddedness seems to disappear, thus basically restructuring the market. The methodological novelty of the research is that exceeding the classic supply–demand algorithm, we compiled a complex viewpoint system adequate to the specialities of the given product characteristics. In our study, the authors intend to survey the special characteristics of health tourism focusing on medical destinations through Hungarian examples since the country's leading position in the global market is well recognized, including medical services.

Machine learning for pricing American options in high-dimensional Markovian and non-Markovian models

In this paper we propose two efficient techniques which allow one to compute the price of American basket options. In particular, we consider a basket of assets that follow a multi-dimensional Black–Scholes dynamics. The proposed techniques, called GPR Tree (GRP-Tree) and GPR Exact Integration (GPR-EI), are both based on Machine Learning, exploited together with binomial trees or with a closed form formula for integration. Moreover, these two methods solve the backward dynamic programing problem considering a Bermudan approximation of the American option. On the exercise dates, the value of the option is first computed as the maximum between the exercise value and the continuation value and then approximated by means of Gaussian Process Regression. The two methods mainly differ in the approach used to compute the continuation value: a single step of the binomial tree or integration according to the probability density of the process. Numerical results show that these two methods are accurate and reliable in handling American options on very large baskets of assets. Moreover we also consider the rough Bergomi model, which provides stochastic volatility with memory. Despite that this model is only bidimensional, the whole history of the process impacts on the price, and how to handle all this information is not obvious at all. To this aim, we present how to adapt the GPR-Tree and GPR-EI methods and we focus on pricing American options in this non-Markovian framework.     

The impact of ECB and FED announcements on the Euro interest rates

We investigate the impact of news in the ECB and FED monetary policy announcements on daily changes in Euro interest rates. We document significant impacts of ECB announcements throughout the period but only until mid 2004 of FED announcements.
