Macroeconomic news announcement effects in financial markets. / Kevin Philip Evans

Swansea University Author: Kevin Philip Evans

Abstract

The interdependence between financial markets and economic fundamentals has formed an important part of financial economics research for many years including the asset pricing, market microstructure and financial econometrics literatures. This thesis contributes to these areas by investigating the i...

This thesis contributes to these areas by investigating the impact of macroeconomic news announcements on financial markets through three substantial empirical chapters.

US news indicators are found to dominate Euro exchange rate volatilities, causing both extreme short lived returns and violent, more persistent increases in volatility.

Jumps are found to be important components of the price process, through their size, intensity and contribution to quadratic variation. Many jumps are caused by US macroeconomic news and the information surprises delivered by data releases explain vast proportions of these jumps, confirming that news has an immediate impact and that asset prices are indeed closely linked to economic fundamentals.</abstract><type>E-Thesis</type><journal/><journalNumber></journalNumber><paginationStart/><paginationEnd/><publisher/><placeOfPublication/><isbnPrint/><issnPrint/><issnElectronic/><keywords>Economics.;Finance.</keywords><publishedDay>31</publishedDay><publishedMonth>12</publishedMonth><publishedYear>2007</publishedYear><publishedDate>2007-12-31</publishedDate><doi/><url/><notes/><college>COLLEGE NANME</college><department>Economics</department><CollegeCode>COLLEGE CODE</CollegeCode><institution>Swansea University</institution><degreelevel>Doctoral</degreelevel><degreename>Ph.D</degreename><apcterm/><lastEdited>2018-08-02T16:24:29.8369989</lastEdited><Created>2018-08-02T16:24:29.8369989</Created><path><level id="1">Faculty of Humanities and Social Sciences</level><level id="2">School of Management - Economics</level></path><authors><author><firstname>Kevin Philip</firstname><surname>Evans</surname><orcid>NULL</orcid><order>1</order></author></authors><documents><document><filename>0042612-02082018162508.pdf</filename><originalFilename>10805370.pdf</originalFilename><uploaded>2018-08-02T16:25:08.1830000</uploaded><type>Output</type><contentLength>32669413</contentLength><contentType>application/pdf</contentType><version>E-Thesis</version><cronfaStatus>true</cronfaStatus><embargoDate>2018-08-02T16:25:08.1830000</embargoDate><copyrightCorrect>false</copyrightCorrect></document></documents><OutputDurs/></rfc1807>
