Analyzing spot and futures contracts in four major regional markets, we first compute ex-ante forward risk premiums in the pre-tax period, then use them to derive market-implied carbon premiums and pass-through rates in the carbon tax and post-tax periods. We find that carbon premiums and pass-through rates became increasingly higher, once the Clean Energy Bill had been introduced and subsequently passed in 2011. We also find strong evidence for a quick reaction of the extracted carbon premiums to changes in opinion polls for the Australian federal election in 2013 and the decision to repeal the tax. On the other hand, during periods where market participants could be relatively certain that the tax would be effective, we find expected carbon pass-through rates between 65% and 140%, which seem to be inversely related to emission intensities.","PeriodicalId":117439,"journal":{"name":"APSA 2009 Toronto Meeting (Archive)","volume":"1225 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121699809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
{"title":"Seasoned Equity Offerings on the Nasdaq: New Evidence on the Asymmetric Information Discount","authors":"M. Adler, Nicholas J Shea","doi":"10.2139/SSRN.1564164","DOIUrl":"https://doi.org/10.2139/SSRN.1564164","url":null,"abstract":"This study investigates the effect of seasoned equity offerings (SEOs) on the NASDAQ. The results confirm that, most of the time, news of a seasoned equity offering is associated with negative stock returns. This is consistent with earlier research that interpreted this effect as indicating the existence of an asymmetric information discount (AsID). However, of the offerings observed in this study, only 65% experienced negative filing-date excess returns and dilutions. This percentage is much lower than the 80% plus reported in earlier studies and falls to approximately 50% by the time issuance take place. Earlier research, furthermore, suggested that these AsIDs were likely to be long lasting. The novelty in this paper is that, in contrast, the discounts that we observe around the SEOs’ filing dates disappear on the average by the time the stock in the SEOs is actually issued. In short, we find that AsIDs on the NASDAQ on the average are short lived and in most cases, are reversed in the relatively brief interval between filing and issuance.","PeriodicalId":117439,"journal":{"name":"APSA 2009 Toronto Meeting (Archive)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131962044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
