Price impact of block trades: the curious case of downstairs trading in the EU emissions futures market

Using high-frequency data from the European Climate Exchange (ECX), we examine the determinants of price impact of €21 billion worth of block trades during 2008–2011 in the European carbon market. We find that wider bid-ask spreads and volatility are characterised by a smaller price impact. Larger levels of price impact are more likely to occur during the middle of the trading day, specifically the four-hour period between 11 a.m. and 3 p.m., than during the first or final hours. Purchase block trades induce a relatively smaller price impact on price run-up, while sell block trades exhibit a larger price impact on price run-up. We conclude that block trades on the ECX induce less price impact than in equity or conventional futures markets, and that a significant proportion of the effects contradict findings on block trades in those markets; thus, we provide the first evidence of the curious bent to block trading in the European Union emissions trading scheme.     

European Green Mutual Fund Performance: A Comparative Analysis with their Conventional and Black Peers

In recent years, several countries have enacted guidelines and/or mandatory laws to increase the presence of women on the boards of companies. Through these regulatory interventions, the aim is to eradicate the social and labor grievances that women have traditionally experienced and which has relegated them to smaller-scale jobs. Nevertheless, and despite the advances achieved, the female representation in the boardroom remains far from the desired levels. In this context, it is now necessary to enhance the advantages of board gender diversity from both ethical and economic points of view. This article examines the relation between board gender diversity and economic results in Spain: the second country in the world to legally require gender quotas in boardrooms and historically characterized by a minimal female participation in the workforce. Based on a sample of 125 non-financial firms listed on the Madrid Stock Exchange from 2005 to 2009, our findings show that in the period analyzed the increase of the number of women on boards was over 98 %. This suggests that compulsory legislation offers an efficient framework to execute the recommendation of Spanish codes of good governance by means of the increase in the number of women in the boards of firms. Furthermore, we find that the increase in the number of women on the boards is positively related to higher economic results. Therefore, both results suggest that gender diversity in boardrooms should be incremented, mandatory laws being a key factor to do so.     

Price Discovery and Trading after Hours: New Evidence from the World’s Largest Carbon Exchange

We investigate the impact of after-hours trading on magnitude and timing of price discovery over the close-to-close period on the world’s largest carbon trading platform, the European Climate Exchange (ECX). Low-volume trading in carbon financial instruments can lead to relatively high levels of price discovery, but the generated pricing has low efficiency levels. This is associated with high levels of informed trades and low levels of liquidity trades. Our results show higher trading volume per minute and greater price efficiency for after hours when compared with regular trading hours. As a result of a higher proportion of informed trades, adverse selection costs for trades after hours are significantly larger than those for trades during the regular trading day.     

Cash holding dynamics and competition intensity: Evidence from UK firms

Using a quasi-natural experiment and various measures of competition intensity, we examine whether an increase in product market competition is a key driver of firm cash holdings. We find that firms increase cash holdings when competition is intense. The results suggest that the degree of increase in cash holdings is magnified among firms exposed to high predatory threat and financing friction. In addition, we examine if increasing cash holdings offers a competitive advantage in the product market. Our results indicate that firms with large cash reserves make gains in market share at the expense of their rivals. Gains in the product market are more pronounced among firms with low exposure to predatory risk and financing frictions.
