Benefit transfer is a method for estimating the value of environmental goods that involves the use of past information on identical or similar goods. This paper considers the extent to which benefit transfer can be based on prior distributions elicited from expert opinion. We propose two alternative methods to elicit the parameters of a prior distribution from experts on environmental valuation. An experiment is carried out on the value of National Parks in Spain. The results from the elicited distributions are compared with the information provided by onsite samples of visitors. The results indicate that individual experts made different predictions about the potential value of the policy areas that were diverse and unable to accurately predict the value for each policy site. However, the average across the elicited distributions approaches the estimated distribution with empirical data and accurately predicts the relative values for the two policy sites considered.  相似文献

We summarize the literature on the effectiveness of combining forecasts by assessing the conditions under which combining is most valuable. Using data on the six US presidential elections from 1992 to 2012, we report the reductions in error obtained by averaging forecasts within and across four election forecasting methods: poll projections, expert judgment, quantitative models, and the Iowa Electronic Markets. Across the six elections, the resulting combined forecasts were more accurate than any individual component method, on average. The gains in accuracy from combining increased with the numbers of forecasts used, especially when these forecasts were based on different methods and different data, and in situations involving high levels of uncertainty. Such combining yielded error reductions of between 16% and 59%, compared to the average errors of the individual forecasts. This improvement is substantially greater than the 12% reduction in error that had been reported previously for combining forecasts.  相似文献

This survey examines the empirical literature on the relationship between public R&D subsidies and private R&D investment over the past five decades. The survey reveals a considerable heterogeneity of empirical results that cannot be explained fully by methodological issues. We aim to provide further explanations of the possible causes of that heterogeneity. In particular, we emphasise a set of issues that, in our view, are critical to understanding the potential effect of public R&D subsidies on private R&D spending. Special attention is paid to the dynamic aspects and composition of firm R&D, the constraints faced by the firm (such as financial constraints), and the amount and source of public subsidies. None of these issues have been investigated in depth. We formulate a set of research assumptions to guide future empirical research in this field.  相似文献

In this paper we investigate the value-relevance of consolidated versus parent company accounting information. In particular we investigate the value relevance of the minority interest components of net total assets and earnings as currently reported and under the full entity approach to consolidated reporting. An Edwards-Bell-Ohlson valuation framework is used to generate results. By this means we cast light on the suitability of accounting regulation being developed based upon the entity or parent company theories of consolidation. We carry out the analysis in the Spanish context and the sample contains 474 observations of non-financial firms quoted in the Madrid Stock Exchange for the period 1991–97. The results from this analysis not only have domestic relevance but provide guidance of a more international nature relating to the impact of group definition, concepts of control and the most value relevant method of consolidated disclosure. The results show that, from a valuation perspective, consolidated information dominates non-consolidated, or parent company, information. However, neither the currently reported minority interest components of net total assets and earnings, nor their values under the full equity method of consolidation, are found to be value relevant. These results raise the question of whether group definitions based on the equity theory of consolidation are the most useful to investors.  相似文献

Extending economic accounts with sets of social and environmental indicators is a first step towards a more integrated analysis of aspects of sustainability problems. In this article, therefore, a proposal is made to nest social and environmental indicators into an existing economic accounting framework. The Social Accounting Matrix (SAM) is taken as a basis, because of its flexibility regarding extensions with non-monetary data addressing social and environmental concerns. The main thrust of the paper is methodological. From the discussion of methodological issues and the application to the SAM for Bolivia for the year 1989, it is concluded that it is, in principle, feasible and relatively simple to extend the SAM with the two sets of indicators. However, additional data will have to be collected to be able to address, more adequately, the problems of sustainability.  相似文献

This paper attempts to find a robust method of measuring competition when firms' operational activities are subject to frictions. The first part theoretically tests the indicative quality of two competition measures, the price‐cost margin (PCM) and the profit elasticity, in a model of monopolistic competition. The second part studies the empirical performance of the indices for a panel of Ukrainian manufacturing firms. This study offers a new approach to measuring profit elasticity that relies on structural estimation of a production function. The estimation methodology retrieves a productivity index that is adjusted to imperfect competition. The proposed method of measuring profit elasticity is found to be robust to frictions, but the PCM and traditional profit elasticity are biased, especially when the intensity of competition is low. Empirical findings show that competition exhibits a significantly positive correlation with aggregate productivity performance, while its impact on firm productivity is nonlinear.  相似文献

This paper finds that participants in the European Central Bank’s Survey of Professional Forecasters have submitted forecasts that are consistent with a (mostly forward-looking) empirical version of the New Keynesian Phillips Curve for the euro area. The estimation technique takes advantage of the panel nature of the Survey of Professional Forecasters’ dataset to exploit both its time series and cross-section dimensions, and to control for unobservable individual heterogeneity across forecasters. The estimation results suggest that euro-area inflation forecasts have reacted less to unemployment forecasts after the start of the financial crisis but another cost measure (energy inflation) remains significant. This finding is consistent with a flatter Phillips Curve in the euro area after 2007. However, the reasons suggested by the International Monetary Fund for this finding, namely a better anchoring of inflation expectations and increases in structural unemployment do not seem to find support in the survey data. Instead, the expectations for compensation per employee submitted by professional forecasters are consistent with the existence of downward real-wage rigidities in euro-area labour markets.  相似文献

ABSTRACT

The paper makes three contributions to the understanding of the post-crisis European banking governance. First, it offers a more comprehensive approach to banking governance, beyond the Banking Union, through its concept of ‘New European Banking Governance’ (NEBG) that incorporates EU state aid rules and fiscal regulations. Second, it considers the impact of NEBG on democratic institutions and processes in EU member states, an under-researched topic in the literature on European banking governance. Finally, through its in-depth case study of Slovenia it considers the NEBG in relation to peripheral Eurozone states. It argues that the post-crisis banking governance framework of the EU not only severely constrained the Slovenian state in its policy choices but rearranged its policy-making institutions in a way that restricted and continues to restrict democratic banking policy formation.  相似文献
