虚拟会议一定是明确的——如何定义新型会议活动的战略价值

过去会议人士使用虚拟会议只是一次性的，今天，他们要把虚拟会议技术融入策略性管理中，成为其中的一部分。根据MPI基金会和全球战略会议管理公司Maxvantage最近进行的调查结果显示，部分公司每年安排了上百场的虚拟会议。 这份研究结果通过网上问卷调查和定性访谈的方式得出，展示出业内专家对于虚拟会议定义的一致性，但是其在各...     

Analysing pollution by way of vertically integrated coefficients, with an application to the water sector in Aragon

In this paper, we adopt Pasinetti's approach of vertically integratedsectors in order to disaggregate pollution into its most significantcomponents. Vertical integration allows us to obtain five components(and at least five measurement indices) corresponding to eachsector and each type of pollution. These indices overcome someof the deficiencies of the traditional Rasmussen-type coefficients.The empirical application is carried out by reference to thewater sector in Aragon, a region which lies in north-easternSpain, for five polluting factors, namely: water returns, biologicaloxygen demand at five days (BOD5), suspended solids (SS), nitratesand phosphates.     

Assessing industrial buyers' perceptions of quality and their effects on satisfaction

Identifying and measuring the dimensions of perceived quality and their influence on customer satisfaction are important aspects of a firm's quality management efforts. In this study, we develop and test a framework for assessing the perceptions held by industrial buyers from different functional areas (e.g., engineering, purchasing) and the link between those perceptions and customer satisfaction. A procedure for identifying the dimensions of quality and using them to target the industrial marketer's quality improvements is discussed, and the results of testing this methodology are presented. The results suggest that a potentially unique set of quality factors can be used to assess each vendor and that these factors vary across functional area.     

NONPARAMETRIC SURVEY RESPONSE ERRORS*

I present nonparametric methods to identify and estimate the biases associated with response errors. When applied to survey data, these methods can be used to analyze how observable and unobservable characteristics of the respondent, and characteristics of the design of the survey, affect errors in the responses. This provides a method to correct the biases that those errors generate, by using the estimated response errors to “undo” those biases. The results are useful also to design better surveys, since they point at characteristics of the design and of subpopulations of respondents that can provide identification of response errors. Several models are considered.     

Rational speculation and exchange rates

Models of exchange rates have typically failed to produce results consistent with the key fact that real and nominal exchange rates move in ways not closely connected to current (or past) macroeconomic variables. Models that rely on the same shocks to drive fluctuations in macroeconomic variables and exchange rates typically imply counterfactually-strong co-movements between them. We develop a model in which new information leads agents to change their rational beliefs about risk premia on foreign exchange markets. These changes in risk premia work through asset markets to cause real and nominal exchange rates to change without corresponding changes in GDP, productivity, money supplies, and other key macro variables.     

Assessing collaborative, pre-competitive R&D projects: the case of the UK LINK scheme

The paper addresses the evaluation of outcomes of collaborative, pre-competitive R&D projects. It draws on some empirical analysis carried out on data and information gathered under the UK 'LINK' scheme, a programme supporting R&D collaborative projects and assessing collaboration outcomes. A new indicator of performance, based on the outputs of LINK projects, has been constructed. It provides a relative and quite consistent measure of performance for making comparisons among different LINK projects. However it does not correlate with the more subjective grade applied by LINK's own management. For further improving evaluating mechanisms, more attention should be paid to the benefits that universities and companies as well as governments are drawing from R&D collaborations.     

The future of olive groves on sloping land and ex-ante assessment of cross compliance for erosion control

Under the past Common Agricultural Policy (CAP) olive oil subsidy regime, farmers were eligible for subsidies on the basis of the amount of olive oil they produced. This led to an intensification of production, particularly on flat land, and had in most cases negative environmental effects, such as more soil erosion on sloping land and more pollution. With the decoupling of agricultural support under the newly established rules of the CAP, formalised in 2005, cross compliance measures have become obligatory.In this paper an ex-ante assessment is made of the application of cross compliance for soil erosion control (natural cover crops and terrace maintenance) in hilly and mountainous olive groves in Trás-os-Montes in Portugal. A linear programming model was developed to assess the various socio-economic and environmental effects of four different development scenarios for olive groves. The scenarios were developed on the basis of changing market prices, wage rates and subsidies; their effects included shifts towards intensification, abandonment and organic farming. Simulations considering a minimum return to labour constraint showed very high levels of abandonment, particularly in combination with cross compliance obligations. However, even without this minimum return to labour constraint, abandonment would reach more than 20% in three out of the four scenarios. The model showed that cross compliance obligations could be quite effective in reducing erosion, but that they would depress income in all scenarios as a result of higher abandonment and lower percentage shifts towards intensive systems.     

How bank capital buffers vary across countries: The influence of cost of deposits,market power and bank regulation

This paper analyzes the bank and country determinants of capital buffers using a panel data of 1337 banks in 70 countries between 1992 and 2002. After controlling for adjustment costs and the endogeneity of explanatory variables, the results show that capital buffers are positively related to the cost of deposits and bank market power, although the relations vary across countries depending on regulation, supervision, and institutions. Their impact is the result of two generally opposing effects: restrictions on bank activities and official supervision reduce the incentives to hold capital buffers by weakening market discipline, but at the same time they promote higher capital buffers by increasing market power. Institutional quality has the two opposite effects. Better accounting disclosure and less generous deposit insurance, however, have a clear positive effect on capital buffers by both strengthening market discipline and making charter value better able to reduce risk-taking incentives.
