How does public spending affect technical efficiency? Some evidence from 15 European countries
2020
The relationship between government size and economic growth has been widely debated. Revisiting the subject from a distinct angle with respect to the mainstream approach, we provide an empirical analysis of the impact of government size on technical efficiency. The aim of this paper is to estimate the impact of public sector's size and of public expenditure components on 15 European countries’ technical efficiency from 1996 to 2014 by using a True Random Effect model. Using the total public expenditure as a proxy for the government size we estimate simultaneously national optimal production function and technical efficiency by controlling for income distribution and institutional quality. …
Hotel chain performance: a gravity-DEA approach
2011
Performance in business management can be measured in terms of competitiveness and efficiency. Generally speaking, competitiveness is a comparative concept of the ability of a firm, sub-sector or country to sell and supply goods and/or services in a given market, as measured by its market share. Particularly in competitive markets, efficiency plays a key role in determining this ability but it is not, by itself, sufficient. Indeed, while competitiveness has more to do with “pursuing the correct strategy” towards the conservation and/or increase of the market share, operational efficiency is mainly a measure of how well the firm, sub-sector or country under study processes inputs to achieve …
Avantages comparatifs et dynamiques de spécialisation : le cas des pays africains.
2021
In this thesis we analyze the mechanisms linking trade openness and industrialization patterns. We are particularly interested in developing countries, especially those belonging to the African continent, because of their particular form of production specialization— essentially based on agricultural and mining products. Our goal is to better understand the evolution of these forms of specialization in order to identify possible paths of industrial development. Chapter 1 provides a comprehensive overview of the literature on the theoretical determinants of international specialization and pays particular attention to theories emphasizing a dynamic view of comparative advantage. This chapter…

Does Inflation Targeting Affect the Trade-off Between Output Gap and Inflation Variability?
2002
We utilize a stochastic volatility model to analyse the possible effects of inflation targeting on the trade–off between output gap variability and inflation variability. We find that the adoption of inflation targets (in New Zealand, Australia, Canada, the UK, Sweden and Finland) might result in a more favourable monetary policy trade–off (except in Australia and Finland). This conclusion is reached by comparing, first, the economic performance of targeting countries in the 1980s and the 1990s; and second, the economic performance in the 1990s of targeting and non–targeting countries (the USA, Japan, Switzerland, Germany, France and the Netherlands). We focus on two possible explanations f…
O śląsko-małopolskich sporach granicznych w okresie międzywojennym
2017
Celem artykułu jest próba przedstawienia relacji Górnego Śląska z Małopolską i Krakowem w okresie międzywojennym. Relacje te rozwijały się na kilku płaszczyznach: gospodarczej, społecznej, kulturowej. Artykuł niniejszy dotyczy ich pewnego wycinka, a mianowicie śląsko-małopolskiego sporu granicznego jaki wywiązał się między środowiskami politycznymi obu regionów o przywództwo i dominację na obszarze Polski południowej. Podstawową bazę źródłową artykułu stanowi prasa, przeważnie krakowska, warszawska, śląska, nigdy dotąd w takim stopniu nie wykorzystana. Kwestia zasadnicza niniejszego studium sprowadza się do pytania, jakie były źródła i przyczyny opisywanego sporu , jakie czynniki decydowały…
LA FRONTIERA APERTA DI GLORIA ANZALDUA
2020
Con il suo complesso testo Borderlands/La Frontera del 1987, tradotto in italiano solo nel 2000, Anzaldúa ha dato grande impulso alla letteratura e alla coscienza chicana, ponendo al centro del dibattito politico ed estetico la questione/simbolo della frontiera e le sue implicazioni culturali. Borderlands/La Frontera è un testo dove, insieme a diversi stili di scrittura, si mescolano storia e mito, spagnolo e inglese, esperienze personali e poesia. Con quest’opera Anzaldúa ci introduce in uno spazio fronterizo, un luogo di passaggio, contraddizioni e conflitti. Un luogo che è altro da tutto ed è altro ancora. Questo luogo geografico è la frontiera tra Messico e Stati Uniti, una striscia di …

Assessing the marginal cost of reducing greenhouse gas emissions in the English and Welsh water and sewerage industry: A parametric approach
2021
Abstract Reducing greenhouse gas (GHG) emissions involves effort from different sectors of the economy, including the water and sewerage industry. This study estimates the marginal cost of curtailing GHG emissions in the water and sewerage industry using stochastic frontier analysis techniques for a sample of ten English and Welsh water and sewerage companies over the 2010–2019 period. Results illustrated that the average marginal cost of reducing GHG emissions was 0.181 £/Kg CO2 equivalent. The marginal cost estimated notably differs across companies and over time. Findings further illustrate the impact of water companies' operating characteristics on the marginal cost of reducing carbon e…
Minimising value-at-risk in a portfolio optimisation problem using a multi-objective genetic algorithm
2011
[EN] In this paper, we develop a general framework for market risk optimisation that focuses on VaR. The reason for this choice is the complexity and problems associated with risk return optimisation (non-convex and non-differential objective function). Our purpose is to obtain VaR efficient frontiers using a multi-objective genetic algorithm (GA) and to show the potential utility of the algorithm to obtain efficient portfolios when the risk measure does not allow calculating an optimal solution. Furthermore, we measure differences between VaR efficient frontiers and variance efficient frontiers in VaR-return space and we evaluate out-sample capacity of portfolios on both bullish and bearis…
