On December 18, 2003 the Accounting Standards Board of Canada announced that all firms registered in Canada would be required to expense stock options‐based compensation effective January 1, 2004. While a few firms had voluntarily opted to expense stock options prior to this date, the vast majority of firms had not. This study investigates the market reaction to this announcement by listed firms in the Toronto Stock Exchange that continued to disclose option expense rather than report it in the financial statement. We find no average market reaction by our sample firms affected by this mandate around the announcement date, but a significantly negative market reaction during the 5‐day window around the issuance date of the exposure draft. However, in cross‐sectional tests around the mandated expense announcement date, we find a significant negative relationship between the cumulative abnormal returns and the Black–Scholes value (and number) of options outstanding and of options granted the previous year. These results suggest that the magnitude of the market reaction to the mandated expense announcement is related to the firm's usage of options. Our results provide further evidence that stock prices may not fully impound information disclosed in footnotes. 相似文献
This study examines the validity of Samuelson hypothesis and the mixture of distribution hypothesis to uncover time-to-maturity and trading volume as the sources of volatility in gold and copper futures. Exponential generalized autoregressive conditional heteroskedasticity model is used for empirical analysis. Leverage effect is found in copper futures but not in gold futures. We find evidence of the Samuelson maturity effect even after controlling for the trading volume. The mixture of distribution hypothesis is strongly supported. Hence trading volume, a proxy for information arrival, is one of the important determinants of volatility, and it dominates time-to-maturity. The results have implications for setting the desired level of margin requirements in futures contracts, designing effective hedging strategy and strengthening the risk management practices. 相似文献
This study investigates whether the eXtensible Business Reporting Language (XBRL) reporting format provides incremental information value beyond the same 10K/10Q filings previously provided in HTML format. Using a sample from the XBRL Voluntary Filing Program, we document a significant increase in stock price variance on the day when voluntary XBRL reports are filed. We find market response is stronger when more content is filed on the same day. To evaluate relative information value, we decompose the quarterly return variance for three primary news announcements related to earnings including earnings announcement, HTML filing, and XBRL filing. We find XBRL filings have larger relative information value than HTML filings. Our results indicate that the XBRL reporting format provides incremental information content. 相似文献
The day-of-the-week effect in the first and second moments of the return distribution is a well researched area. However,
not many studies have attempted to identify this effect in the comovement or correlation of the markets. This paper models
the day-of-the-week effect in the returns and the conditional correlation for some Asia-Pacific equity markets. The paper
finds a Monday, Wednesday and Friday effects in the returns for some of the markets. The effect is totally absent in the returns
for Australia, Japan and Korea. For the fifteen conditional correlation series estimated, a predominant Tuesday effect is
detected for five series. Three series exhibit a Monday effect. A Thursday effect is detected between the Singapore market
and the markets of Australia, Hong Kong and Thailand. The paper finds no consistent day-of-the-week effect in the returns
and the correlations for this region.

With the onset of the ‘climate change movement’, organisations are striving to include environmental criteria into the supplier selection process. This article hybridises a Green Data Envelopment Analysis (GDEA)-based approach with a new Genetic/Immune Strategy for Data Envelopment Analysis (GIS-DEA). A GIS-DEA approach provides a different view to solving multi-criteria decision making problems using data envelopment analysis (DEA) by considering DEA as a multi-objective optimisation problem with efficiency as one objective and proximity of solution to decision makers’ preferences as the other objective. The hybrid approach called GIS-GDEA is applied here to a well-known automobile spare parts manufacturer in India and the results presented. User validation developed based on specific set of criteria suggests that the supplier selection process with GIS-GDEA is more practical than other approaches in a current industrial scenario with multiple decision makers. 相似文献
This article studies the role of imperfect information in explaining price dispersion. We use a new panel data set on the U.S. retail gasoline industry and propose a new test of temporal price dispersion to establish the importance of consumer search. We show that price rankings vary significantly over time; however, they are more stable among stations at the same street intersection. We establish the equilibrium relationships between price dispersion and key variables from consumer search models. Price dispersion increases with the number of firms in the market, decreases with the production cost, and increases with search costs.相似文献
In recent years, there has been an increase in awareness of trans-boundary pollution that places environmental assets at risk both globally and regionally. Globally, manmade pollutants have degraded the stratospheric ozone shield, the oceans, the atmosphere and the biodiversity of the planet. Regionally, these pollutants have harmed aquifers, rivers, lakes, soils and forests. Harmful effects of acid rains, greenhouse gasses, and thin ozone shield are not concentrated within political boundaries of a country, thus jeopardizing the well-being of people in other countries. These trans-boundary pollution problems—termed as Transnational Public Goods (TPGs)—often share two common features: strategic interactions among nations and public good properties. This paper applies the theory of voluntary provisions of TPGs to the behavior of nations to curb chloro-fluoro-carbon emissions that, in large part, preceded the ratification and institution of the Montreal Protocol on substances that deplete the ozone layer.
Middle-income developing countries rely heavily on commercial bank borrowing for the bulk of their financing requirements, but borrowing from this source cannot be projected with confidence. Privately owned financial institutions are subject to a number of capital and regulatory constraints which can adversely affect (will heavily influence) the level and direction of future lending to developing countries. Moreover, the volatility and short-term character of commercial bank lending suggests an urgent need to reduce the role of commercial banks in recycling the OECD and OPEC surplus, and to create new mechanisms designed to ensure more stable and longer term sources of capital to developing countries. 相似文献
In order to analyse the effects of policy reforms, output supply and factor demand responses to input and output prices for Malawian agriculture are estimated in this article in a multiple-output, multiple-input framework. The implications of various structural adjustment policies implemented in Malawi are analysed using the model results for their impact on the smallholder agricultural sector. The results of the analysis indicate that removal of fertiliser subsidy – a major component of market reform policies – does not substantially reduce the production of maize, the major staple food in Malawi. However, when implemented in appropriate sequence along with other output market liberalisation policies and increased investment in infrastructure, such a policy is likely to increase the productivity of smallholder agriculture. 相似文献
