The comfortable perception that global environmental challenges can be met through marginal lifestyle changes no longer bears scrutiny. The cumulative impact of large numbers of individuals making marginal improvements in their environmental impact will be a marginal collective improvement in environmental impact. Yet, we live at a time when we need urgent and ambitious changes. An appeal to environmental imperatives is more likely to lead to spillover into other pro-environmental behaviours than an appeal to financial self-interest or social status.

A system of regression equations for analyzing panel data with random heterogeneity in intercepts and coefficients, and unbalanced panel data is considered. A maximum likelihood (ML) procedure for joint estimation of all parameters is described. Since its implementation for numerical computation is complicated, simplified procedures are presented. The simplifications essentially concern the estimation of the covariance matrices of the random coefficients. The application and ‘anatomy’ of the proposed algorithm for modified ML estimation are illustrated by using panel data for output, inputs and costs for 111 manufacturing firms observed up to 22 years.  相似文献

This paper seeks to determine whether Danish managers exercise discretionary accruals to reach earnings forecast targets they voluntarily specify in conjunction with initial public offerings (IPOs). Because the Danish accounting and legal environment is more permissive than the US, we use Denmark as a natural laboratory for learning how business would occur without strict rules, enforcement and sanctions. Danish managers often volunteer pro forma financial statements for results that are expected to occur subsequent to the IPO. We examine a sample of 58 Danish firms that issue voluntary management earnings forecasts in connection with IPOs that occur between 1984 and 1996. The evidence we uncover strongly suggests that pre-managed earnings are adjusted toward these targets. In contrast with Kasznik's (1999 Kasznik, R. (1999). On the association between voluntary disclosure and earnings management. Journal of Accounting Research, 37: pp. 57–81 [Google Scholar]) results related to voluntarily forecasting American firms, managers of Danish firms exercise discretionary accruals to mitigate earnings forecast errors regardless of whether pre-managed earnings are less, or greater, than the IPO forecast amount.  相似文献

The theme is Arrow's requirement in his theorem of 1951 on methods for group choice, that the choice be independent of irrelevant alternatives. The attention is drawn to (1) his own explanation of this requirement in 1972, which is a quite different understanding than has been discussed in the voluminous literature on the theorem, (2) that Arrow, in fact, in 1985 showed an understanding for how irrelevant alternatives might in a meaningful way influence the group choice, (3) that admittedly the border-line between irrelevant and relevant alternatives in Arrow's original statement is arbitrary, and (4) that Arrow, if he had observed the final thought in the origin of the group theory by Borda, which he admittedly did not, might have realized that Borda's method stringently estimates the relevance of each alternative for the result.The author expresses his surprise that a theoretical conclusion based on an arbitrary fundament has been admired so long.  相似文献

Given that electricity distribution is undertaken via a network, it is expected that costs of production are affected both by the nature of the network and the volume of physical output distributed via the network. This two-dimensional concept of firm size, that is involving network size (number of customers) and the level of physical output (kWh), also corresponds to the distinction between productivity measures of returns to density and returns to scale.This approach has been used to specify a restricted multioutput cost function and to estimate this function for the Norwegian electricity distribution industry through the use of a flexible functional form (translog). The results indicate that no economies of scale are present in the industry even for small plants when measured correctly, but that economics of density are present.  相似文献

This paper investigates whether there is a different impact from changes in ‘new’ and ‘old’ economy stock valuations on private investment for seven OECD economies. A vector autoregressive model is estimated for each individual country, using quarterly data over the period 1990–2000. It is found that the impact from changes in valuations of new economy stocks to investment is roughly the same in North America and in the United Kingdom as in continental Europe. By contrast, the impact from changes in old economy stock valuations on investment is, in general, larger in North America and in the United Kingdom than in continental Europe. Finally, the results suggest that in continental Europe the impact on investment from changes in the valuation of new economy stocks is bigger than for old economy stocks, whereas for North America and the United Kingdom, the impact is more similar.  相似文献

The dynamics of export market exit and firm closure have found limited attention in the new heterogeneous-firms trade literature. In fact, several of the predictions on firm survival and exit stemming from this new class of models are at odds with the stylized facts. Empirically, higher productivity firms survive longer, most firm closures are young firms, higher productivity exporters are more likely to continue to export compared to less productive exporters and market exits as well as firm closures are typically preceded by periods of contracting market shares. The present paper shows that the simple inclusion of exogenous economy wide technological progress into the standard Melitz (2003) model generates a tractable dynamic framework that generates endogenous exit decisions of firms in line with the stylized facts. Furthermore, we derive the effects of faster technological progress and trade liberalization on export market exit and firm closure.  相似文献

We examine how workers adjust in response to an unexpected job loss. Using the closure of military bases in Sweden, we find that displaced workers experience permanent income losses and immediately adjust along two main channels: regional and sector mobility. Displaced military workers are more likely to move to another municipality, start commuting, and change sectors. We also find that workers with mobility restrictions are less likely to change regions and they exhibit lower earnings in the longer run, a result that might help to explain some of the permanent income losses found in the literature.  相似文献
