Demand for international telephone traffic in Spain: An econometric study using provincial panel data

In this study we model the demand for outgoing international telephone traffic in Spain. We make use of a standard theoretical framework that incorporates the special characteristics of this type of telephone service. Consequently, equations for real expenditure per line and for the number of international calls per line are estimated.We use annual data for the 50 Spanish provinces for the period 1985–1989, and employ appropriate panel data techniques. The selected equations (one for expenditure per line in international traffic and another for the number of international calls per line) pass a battery of diagnostics. We conclude that this type of traffic, whether measured by expenditure per line or by the number of international calls per line, presents both high income and price elasticities. Moreover we find that price and income affect both the number of calls and their average duration.Likewise, we find a significant increase in social welfare when a tariff rebalancing that maintains the profit of the operating company is carried out.     

Modelling the demand for optional classes of local measured telephone service

There is currently a strong movement under way in the telephone industry to unbundle access charges and usage charges for local telephone service. Pricing schemes with separate access and usage charges are called measured service options. Predicting which option a household will choose involves analysing a selection problem, referred to as the choice of class of service. This choice is estimated in a nested logit framework. The three major findings of this study are that the measured options are perceived as being very similar, many personal calls may originate from businesses if the pricing structure is changed, and that the flat rate price will have to be nearly doubled before the ‘take rate’ for flat rate pricing is significantly diminished.     

Customer participation in the service encounter

This paper considers the role of service customers in those service encounters where the customer participates in the service production and delivery process, and the customer factors, motivations and incentive mechanism to participate in service delivery are analyzed. This study explores the relationship between service quality and service customer participation in the service encounter and the effect of customer participation on service providers＇ job stress. Finally, the management implications about customer participation in the service encounter from the findings are discussed.     

The existence of factor substitution in the primary aluminium industry: A multivariate error-correction approach using Norwegian panel data

This paper presents an econometric analysis of factor demands in the Norwegian primary aluminium industry using annual plant-level panel data. The translog cost function approach is applied, and a multivariate error-correction model of the cost shares of labour, raw materials and electricity is estimated. Capital is assumed tobe quasi-fixed. The hypothesis of fixed input coefficients is rejected for this industry, but the estimated own-price and cross-price elasticities suggest that relative price variations have limited effect on conditional factor demands.     

国有企业改制效果的实证研究

本文通过对1998至2003年间全部国有企业和规模以上非国有企业的数据进行分析来研究我国国有企业改制的效果。我们不仅考察了改制对企业经济效益的影响,而且考察了改制对企业社会效益指标的影响。此外,我们还分析了改制影响经济效益的渠道、国有控股和非国有控股的差别、以及改制效果的可持续性。本文的主要发现是:改制后企业经济效益显著提高,并且主要来自于代理成本的降低,表现为管理费用率的下降;改制带来了一定的社会成本,但和国际经验相比程度不是很大;国有控股改制社会效益较好,而非国有控股改制经济效益较好;改制效果在一定期间内持续。     

2000年以后福利国家养老金体系发展趋势考察——基于“去商品化”的分析框架

文章根据"去商品化"的分析框架,对2000年以后三种福利模式国家的养老金体系发展趋势进行了考察。研究发现,社会民主主义福利模式国家的养老金体系表现出去商品化的趋势,体现了社会民主主义福利模式对社会权利及普惠主义思想的回归;自由主义福利模式国家的养老金体系呈现出继续商品化的趋势,是对1990～2000年间再商品化趋势的继续和发展,体现了自由主义福利模式对市场作用的信奉;保守主义福利模式国家的养老金体系同样表现出一定的商品化趋势,但这是各个社会群体博弈后,选择商品化手段对养老金体系进行调整的过程。     

The participation of Russian households in the informal economy: Evidence from the VTsIOM data

This study presents the size and structure of secondary employment in Russia, analyses the determinants of Russian informal secondary employment, and discusses differences between job qualifications in a main job and those in a secondary job. We estimate that 27 percent of Russia’s GDP was produced in the informal economy during 1997–98 and informal secondary employment amounts to about 20 percent of value added produced in the informal economy. We found that the probability of holding an informal secondary job as opposed to a formal one is positively associated with higher wage rates and lower education. However, there is little evidence that low income is correlated with holding an informal secondary job. We also found evidence that an informal secondary job requires lower job qualifications as compared to a formal one. Again, low income is not significant in determining differences between job qualifications in a main job and those in a secondary job. JEL classification: J22, J24, O17, P20.     

The driving forces of the change in China's energy intensity: An empirical research using DEA-Malmquist and spatial panel estimations

Energy shortage and environmental degradation have become significant hurdles for China's sustainable development nowadays. One of the most efficient and effective ways to ease energy shortage is to sufficiently reduce energy intensity. In the extant literature on the influential factors of China's energy intensity, the regional imbalance and spatial spillover effects were basically ignored, which may yield to biased and unreasonable results. As a result, in this paper, the driving forces of China's provincial energy intensity were for the first time investigated by combining the Data Envelopment Analysis (DEA)-Malmquist and spatial panel approaches for the period between 2000 and 2014. The results indicate that technological progress plays a dominant role in decreasing China's overall energy intensity. In both the Eastern and Central regions, the technological progress and its components can decrease energy intensity, while this effect doesnot significantly exist in the Western region. Rapid industrialization should be responsible for China's currently high energy intensity, while energy price hiking is conducive to the decrease in energy intensity. Moreover, there is also clear evidence that these factors influence on energy intensity partly through the spatial spillover effects.     

Testing the relationship between competition and efficiency in banking: A panel data analysis

The relationship between competition and efficiency in the banking sectors of five EU countries is investigated using Granger-type causality test estimations. We find positive causation between market power and efficiency, whereas the causality running from efficiency to competition is weak.     

Economic determinants of the consumption of alcoholic beverages in Canada: a panel data analysis

In this article, the economic determinants of the demand for three alcoholic beverages (wine, spirits, and beer) are investigated with a focus on the price, income and unemployment effects. The investigation is conducted within the fixed effects panel regression framework using a balanced panel for ten Canadian provinces spanning the years 1981–2004. The estimated own price elasticities indicate that increased government taxation is an effective tool for curtailing the consumption of spirits (at the expense of lower government tax revenue), but it is less effective for curtailing the consumption of wine or beer. The cross-price elasticity estimates reveal that taxing beer or spirits may not be an effective tool for encouraging consumption switch from these alcoholic beverages to wine in light of wine’s greater health benefits. Income emerges as an important determinant of the consumption of both wine and spirits but not of beer, whereas unemployment emerges as an important determinant of the consumption of beer but not of wine or spirits. With respect to unemployment, we find no support for the addiction hypothesis in the case of wine and spirits and strong support for the severe budget constraint hypothesis in the case of beer.     

Assessing participation in voluntary environmental programmes in the developing world: the role of FDI and export orientation on ISO14001 adoption in Thailand

Empirical assessments of the determinants of firm participation in Voluntary Environmental Programmes (VEPs) in the developing world are largely absent from the environmental regulation literature, leaving a number of important factors unique to such countries unexplored. This article examines these factors, namely the roles played by Foreign Direct Investment (FDI) and export orientation, in addition to factors deemed important in the industrialized world context to the problem of ISO14001 adoption in one developing nation, Thailand. We make use of unique primary data from 494 firms, and focus on three important industries, the resource-based food and beverages industry, the labour-intensive textiles and wearing apparel industry, and the more high-technology electronics and electrical appliances industry. We find that FDI plays a role in ISO14001 adoption, especially FDI from Organization for Economic Co-operation and Development (OECD) and ISO14001-rich countries. Other important determinants include firm size, experience with ISO9000, and production of intermediate products. Firms faced with fewer obstacles to environmental improvements such as those facing lower costs, having more understanding of the procedure, and with greater access to the appropriate technology are also more likely to adopt ISO14001.     

Orientation and community participation of ecological development： a case study of Hutuo River in Shijiazhuang City, China

Entrusted to by Shijiazhuang municipal Party committee and government,Shanghai Tongji University finished ＂The General Planning of Ecological Development Project of Hutuo River in Shijiazhuang City＂.It aims to build Hutuo River into a wind-breaking and sand-fixing barrier and ecological protect district in the north of Shijiazhuang based on the recovery of natural ecology to improve the environment of Shijiazhuang city.It also intends to develop the district lightly and build it into a nature beauty spot and big park.After the construction for several years,the general environment of this district has been greatly improved.But during the development,the man-made landscapes are highlighted excessively,which deviates from the construction of nature landscape.The currency of constructing big leisure park gradually comes into being,so the recovery of nature ecological is slow.So,this paper intends to make the orientation to ecological development of Hutuo River in Shijiazhuang city and puts forward the community participation to promote the future development of ecotourism in Shijiazhuang.     

Economies of scale in the US computer industry: An empirical investigation using data envelopment analysis

Up to recently, economists have had no good tools to measure the returns to scale of individual corporations in an industry. Data envelopment analysis (DEA) is a linear programming technique for determining the efficiency frontier (the envelope) to the inputs and outputs of a collection of individual corporations or other productive units. While DEA offers an avenue for calculating the returns to scale of individual corporations, the approach has been riddled by mathematical complications arising from the possibility of alternate optima. The present paper develops theory for calculating the entire range of these alternate optima. Furthermore, in a quite ambitions empirical application, DEA is employed to determine the time path of returns to scale of all publicly held U.S. computer companies over the time period 1980–1991. For the great majority of companies, a unique time path is obtained; only in less than 4 percent of the linear programming calculations is an entire range of alternate optima obtained. The results indicate that the computer industry was polarized into two camps: large aging corporations with decreasing returns to scale, and swarms of small upstart companies with advanced technology exhibiting increasing returns to scale.     

An international study of persistence in output: Parametric estimates using the data dependent systems approach

This paper parametrically obtains estimates of persistence in output using Pandit's (1977, 1982) Data Dependent Systems approach for modelling autoregressive and moving average processes. The estimates are based on over a century of annual data for the rate of change of output in nine industrialized countries. The sensitivity of estimates to various model selection criteria is examined. While persistence in output is found to be sensitive to model selection criteria, the output of all countries including the United States is found to have a substantial degree of persistence if the ARMA models are chosen according to the Schwarz Bayesian Criterion, but excluding the ARMA models whose moving average roots are near the unit root (which involves pile-up phenomenon). Moreover, the parametric estimates of persistence are shown not to have the known upward bias problem commonly associated with parametric estimates of persistence relative to nonparametric estimates.     

Modeling corner solutions with panel data: Application to the industrial energy demand in France

This paper provides an empirical application of Lee and Pitts (1986) approach to the problem of corner solutions in the case of panel data. This model deals with corner solutions in a manner consistent with the firm behavior theory while controlling for unobserved heterogeneity. In this model, energy demand at industrial plant level is the result of a discrete choice of the type of the energy to be consumed and a continuous choice that defines the level of demand. The econometric model is, essentially, an endogenous switching regime model which requires the evaluation of multivariate probability integrals. We estimate the random effect model by maximum likelihood using a panel of industrial French plants from the paper and pulp industry. We calculate empirical price elasticities of energy demand from the model. We also study the effects on energy demand of an environmental policy aimed at reducing CO₂ emissions.

The patterns and determinants of longevity in Russia's regions: Evidence from panel data

In this paper we examine whether regions of Russia have been converging or diverging in their longevity levels during the 1990s and evaluate the divergence effect of the 1998 financial crisis. We also estimate the impact of changes in poverty and public health spending on inter-temporal variations in longevity using regional-level panel data for 77 Russian regions from 1994 to 2000. Finally, we investigate the extent to which the gradual recovery in longevity observed after 1994 was derailed by the 1998 financial crisis and the public policy shifts required for regions to regain their Soviet-era levels of longevity. We find a significant negative effect of the 1998 crisis on longevity independently of the factors related directly to poverty and public health spending. In addition, a permanent negative shock to the incidence of poverty and the amount of publicly-provided health care in a region has enduring consequences on the population's health. Finally, the effect of increases in public health spending on longevity is related positively to the incidence of poverty. Journal of Comparative Economics 33 (4) (2005) 788–813.     

The Equivalency Principle for Discounting the Value of Natural Assets: An Application to an Investment Project in the Basque Coast

Making decisions about optimal investments in green infrastructure necessitates setting social discount rates. This paper suggests a practical way for determining the discount rate for projects or programmes in which one of the options is to maintain or restore land to an undeveloped state. We propose an “equivalency principle” to derive a simple rule that sets the discount rate. The rule is based on the premise that the long term value of a piece of undeveloped land ought to be at least the same as the value of an identical piece of land in the vicinity to which permission has been granted for development. We illustrate this principle with various case studies and we apply it to a contentious investment project in the Basque Country associated with the regeneration of a large scale harbour that involves reclaiming undeveloped land that has important ecological values, including for the conservation of a marine ecosystem.
