This paper examines whether the level of voluntary disclosure affects the association between current returns and future earnings. Economic theory suggests that firms might find it advantageous to provide additional pieces of information (i.e. voluntary disclosure) to investors and analysts. Our results indicate that more voluntary disclosure does not improve the association between current returns and future earnings (i.e. current returns do not reflect more future earnings news). This finding raises the question of whether voluntary information in the annual report contains value‐relevant information about future earnings or if investors are simply not capable of incorporating voluntary information in the firm value estimates. 相似文献

In order to evaluate the relation between the consumption pattern of various household types and their CO2 requirements, we combine input-output tables energy flow matrices, CO2 emissions factors, and national consumer survey statistics into an integrated modelling framework, and relate differences in household types to differences in private consumption and again to differences in CO2 emissions. We identify household characteristics with a significant influence on CO2 emissions. Comparing our results with those of other studies reveals that national differences in climate and population density cause differences in the contribution to CO2 emissions. Finally, national differences in income and expenditure elasticities of both energy and CO2 are due to differences in the disparity in CO2 intensities amongst commodities and to the model's assumptions on foreign technology. 相似文献

This article examines 40 years of research conducted in the area of Out-of-Stocks (OOS). Two research streams originating from the Progressive Grocer (1968) study are reviewed. The first stream dealt with demand side issues and analysed consumer responses to OOS. The other dealt with supply side issues and analysed the extent and root causes of OOS situations as well as how to improve OOS. Four paradoxes are derived from the review and are discussed: 1) OOS rates largely seem to fall into an average level at about 7 to 8% despite 40 years of research; 2) only sparse attempts have been made to integrate the two research streams; 3) there is an emphasis on minimizing OOS rather than relying on basic trade-offs as addressed by Economic-Order-Quantity theory to optimize OOS levels; and 4) despite clear evidence of the store as the major contributor to OOS situations, the store has largely remained a ‘black-box’ in OOS research. Finally, the study suggests that OOS research can integrate the notions of the two streams by showing how the conditions for consumer responses can be translated into different degrees for costs of understocking taken from Economic-Order-Quantity theory. This will have important implications for the management of OOS. 相似文献

Flexible jobs make up a larger share of the Dutch labour market than in almost any other Western country. Recent graduates
in the Netherlands are particularly likely to take flexible jobs. In this study we examine why recent graduates enter into
temporary contracts and whether flexible jobs offer a poorer match for graduates’ qualifications than permanent jobs. We find
that recent graduates that enter into flexible jobs face large wage penalties, a worse job match and less training participation
than graduates who take permanent jobs, even after correcting for differences in ability. When the labour market situation
for a particular field of education deteriorates, more recent graduates are forced into flexible jobs, threatening their position
on the labour market in the long run. Flexible work among recent graduates is unrelated to their willingness to take risks.
Only for university graduates is there any indication that flexible jobs may provide a stepping stone to permanent employment. 相似文献

CO2 Multipliers in Multi-region Input-Output Models 总被引:1,自引:0,他引:1
In order to achieve equitable reduction targets, international trade has to be taken into account when assessing nations' responsibility for abating climate change. Especially for open economies such as Denmark, greenhouse gases embodied in internationally traded commodities can have a considerable influence on the national 'greenhouse gas responsibility'. We set up a five-region input-output model including Denmark, Germany, Sweden and Norway in order to calculate CO2 multipliers and trade balances. We investigate multidirectional feedback between these countries, and hence the error inherent in a single-region input-output model. We also examine the effect of aggregation on the model results. In the case of Denmark, an 11 Mt CO2 trade surplus resulting from a single-region model turns into balance when multidirectional trade is considered. Moreover, aggregated models are likely to result in significant errors. Therefore, both the type and the degree of aggregation used for modelling CO2 responsibilities could have a major bearing in international negotiations. 相似文献

We study the forecasting of future realized volatility in the foreign exchange, stock, and bond markets from variables in our information set, including implied volatility backed out from option prices. Realized volatility is separated into its continuous and jump components, and the heterogeneous autoregressive (HAR) model is applied with implied volatility as an additional forecasting variable. A vector HAR (VecHAR) model for the resulting simultaneous system is introduced, controlling for possible endogeneity issues. We find that implied volatility contains incremental information about future volatility in all three markets, relative to past continuous and jump components, and it is an unbiased forecast in the foreign exchange and stock markets. Out-of-sample forecasting experiments confirm that implied volatility is important in forecasting future realized volatility components in all three markets. Perhaps surprisingly, the jump component is, to some extent, predictable, and options appear calibrated to incorporate information about future jumps in all three markets. 相似文献

The relative importance of foreign and domestic shocks for the Swedish postwar business cycle is examined in a neoclassical stochastic growth model of a small open economy. Since recent research has shown that fiscal policy shocks may be important for business cycles, I extend previous work in the literature by allowing for stochastic fiscal policy. It is found that the introduction of fiscal policy improves the empirical fit of the model, although not significantly so when hours worked are detrended with the HP filter. The results suggest that domestic shocks are more important than foreign shocks for output fluctuations. Among the domestic shocks, innovations in fiscal policy seem to have been more important than technology shocks during this period. Foreign shocks are very important for fluctuations in the real exchange rate and the current account. 相似文献

This article examines the origins and effects of the evolution of the Danish pork industry characterised by three main merger waves resulting in 43 realised mergers and takeovers. The findings illuminate – in contrast to the traditional strategically motivated rationale – that the majority of the mergers were realised by cooperatives due to the inability to give the pig farmers competitive yearly refunds vis-à-vis local competitors, to financial difficulties or to the lack of investment capability of one of the merging parties. Despite a high-risky strategy, mergers and takeovers became the preferred consolidation mean due to capital constrains and the ‘close’ ownership structure of the cooperatives. Moreover, the study demonstrates that the outcomes of the M&A activities were generally positive. 相似文献

We study Swedish implementation of the European Union’s Water Framework Directive, and compare the current implementation strategy with more flexible ‘bubble’ schemes, where measures can be traded among various locations within the same river system to reach the overall environmental target. Two different Swedish river systems, the Mörrum system with small-scale hydropower plants, and the Ångerman system with larger plants, are studied. We find that the environmental benefits that current policies are likely to accomplish could be achieved at well under half the cost in the Mörrum system, and at less than a tenth of the cost in the Ångerman system. 相似文献

The discussions raised in the theories of convergence and diversification of industrial relations are again becoming relevant due to the Single European Market and the proposals coming from the EC-Commission regarding a common EC regulation and harmonisation of the European labour market. How far the EC-development will imply an internationalisation of European industrial relations is analysed here. 相似文献
