CO2 Prices, Energy and Weather
2007
One of the main objectives of the European Union Emission Trading Scheme is the establishment of a market price level for allowances that show to European CO 2 emitting installations the environmental impact of their polluting activities. The aim of this paper is to focus on the daily price changes during 2005 in an attempt to examine the underlying rationality of pricing behaviour. Specifically, we study the effect of those weather and non-weather variables that academic and market agents consider as the major determinants of the of CO 2 price levels. The results show that the energy sources are the principal factors in the determination of CO 2 price levels, and that only extreme temperat…
Free admission in museums and monuments : An exploration of some perceptions of the audiences.
2008
This paper considers the theme of the audiences' perceptions of free admission in national French museums and monuments. The results show that, from an individual perspective, perceptions of free admission are linked to perceptions of price, money and payment, hence complementing perceptions expressed in a collective perspective (a symbolic, political measure causing either adhesion or rejection). These perspectives are generally put forward by both advocates and opponents of the measure in their discussions. These different visions of free admission have managerial implications for managers of museums and monuments. Copyright © 2007 John Wiley & Sons, Ltd.
DETERMINANTS OF PROFITABILITY IN SPANISH FINANCIAL INSTITUTIONS. COMPARING AIDED AND NON-AIDED ENTITIES
2015
The last financial crisis has led to the greatest contribution of public funds ever made to Spanish banks. This paper studies why the need for support has been asymmetric, with not all of the institutions requiring aid. Based on profitability of assets (ROA), we determine using panel data econometric and logit response models the components of profit and loss accounts that generated profitability as well as the factors leading to some entities to ask for aid. The analyses show that before the beginning of the crisis there were significant differences between entities that needed aid and those that did not. The most profitable banks grounded their success in the traditional revenue component…
Natural resources, electrification and economic growth from the end of the nineteenth century until World War II
2005
RESUMENLas repercusiones de la nueva rúente de energía, electricidad, en el crecimiento económico de una muestra de países –Estados Unidos, Reino Unido, Francia, Italia, España y Canadá- caracterizados por sus diferentes dotaciones de recursos carboníferos es el principal objetivo de este artículo. La nueva energía, entre otras ventajas, redujo la dependencia de los recursos naturales de carbón al poder generarse a partir de diferentes energías primarias: agua o carbón. Con el fin de valorar la importancia de esta reducción de la dependencia del carbón, se presenta una base de datos de los recursos energéticos para los seis países, se muestra que los precios relativos de la electricidad fre…
The Classical Notion of Competition Revisited
2013
This article seeks to fill a lacuna within classical economics concerning the process of market price determination in situations of market disequilibrium. To this aim, first we distinguish the classical notion of free competition from the Walrasian notion of perfect competition and we argue that the latter is beset with some theoretical difficulties alien to the former. Second, we reconstruct in some detail Smith’s and Marx’s views concerning market price determination and show that Marx’s extensive use of metaphors and numerical examples foreshadows the modern taxonomy of buyers’ market, sellers’ market, and mixed strategy equilibrium in the capacity space of a standard Bertrand duopoly m…
The Home Bias in Equities and Distribution Costs
2015
We show that incorporating distribution costs into a general equilibrium model of international portfolio choice helps to explain the home bias in international equity investment. Our model is able to replicate observed investment positions for a wide range of parameter values, even if agents have an incentive to hedge labor income risk by purchasing foreign equity. This is because the existence of a retail sector affects both the correlation of domestic returns with the domestic price level and the correlation between financial and non-financial income.
Mobile telephony in emerging markets: The importance of dual-SIM phones
2020
Abstract A substantial share of customers in emerging markets use dual-SIM phones and subscribe to two mobile networks. A primary motive for so called multi-simming is to take advantage of cheap on-net services from both networks. In our modelling effort, we augment the seminal model of competing telephone networks á la Laffont, Rey and Tirole (1998b) by a segment of flexible price hunters that may choose to multi-sim. According to our findings, in equilibrium, the networks set a high off-net price in the linear tariffs to achieve segmentation. This induces the price hunters to multi-sim. We show that increased deployment of dual-SIM phones may induce a mixing equilibrium with high expected…
Demand for Primary Schooling in Rural Mali : Should User Fees Be Increased ?
1996
International audience; This paper presents estimates of the price elasticity of demand for primary schooling, using household and school survey data from rural Mali. The elasticity of enrolment with respect to the local school fee is compared with the effects on enrolment of distance to the school and various indicators of school quality, including books per classroom and the number of grades offered. Fees have a negative effect; however, certain improvements in school quality could easily offset in terms of enrolment any negative effect of higher fees to finance such improvements. For example, the astonishingly low average of two books per classroom could be doubled for a 10 per cent incr…
Second-best taxation for a polluting monopoly with abatement investment
2018
This paper characterizes the optimal tax rule to regulate a polluting monopoly when the firm has the possibility of investing in an abatement technology and the environmental damages are caused by a stock pollutant. The optimal policy is given by the stagewise feedback Stackelberg equilibrium of a dynamic policy game between a regulator and a monopolist. The regulator playing as the leader chooses an emission tax to maximize net social welfare, and the monopolist acting as the follower selects the output and the investment in abatement technology to maximize profits. We find that the optimal tax has two components. The first component is negative and equal to the gap between the marginal re…
A branch & bound algorithm for cutting and packing irregularly shaped pieces
2013
Abstract Cutting and packing problems involving irregular shapes, usually known as Nesting Problems, are common in industries ranging from clothing and footwear to furniture and shipbuilding. Research publications on these problems are relatively scarce compared with other cutting and packing problems with rectangular shapes, and are focused mostly on heuristic approaches. In this paper we make a systematic study of the problem and develop an exact Branch & Bound Algorithm. The initial existing mixed integer formulations are reviewed, tested and used as a starting point to develop a new and more efficient formulation. We also study several branching strategies, lower bounds and procedures f…
