This paper examines the abnormal returns in merger withdrawals in Australia, especially distinguishing the market response between private and public targets. We also study the determinants of those abnormal returns, including the method of payment and the impact of financial crisis periods. Using the event study method, we document that in the Australian context, the announced withdrawal of mergers involving private targets creates significantly negative valuation effects in comparison with the valuation effects in withdrawal of mergers involving public targets. We also find that a financial crisis period strongly affects abnormal returns of merger withdrawals. However, the method of payment does not have any impact on the abnormal returns.

Ketidakpastian politik sering menjadi peristiwa khusus yang berpengaruh terhadap return portofolio saham. Tujuan dari penelitian ini adalah untuk menguji pengaruh pengumuman pembentukan kabinet Indonesia Maju 2019-2024 terhadap harga saham yang terdaftar pada Indeks Syariah (ISSI) dan Indeks Harga Saham Gabungan (IHSG). Penelitian ini menggunakan metode event study untuk melihat adanya reaksi pasar yang dapat dilihat dari adanya abnormal return pada saham. Indikator yang digunakan adalah nilai average abnormal return (AAR) dan cumulative average abnormal return (CAAR). Hasil pada penelitian ini menunjukkan bahwa terdapat nilai AAR yang negatif dan signifikan pada sehari sebelum (t-1) dan setelah (t+1) pengumuman menteri pada indeks syariah dan pasar. Selain itu, terdapat perbedaan yang signifikan nilai cumulative average abnormal return (CAAR) sebelum dan sesudah pengumuman menteri pada t (-7,7) untuk portofolio ISSI dan t (-10,10) untuk portofolio IHSG. Adanya reaksi negatif invetor mengindikasikan terdapat kebingungan investor saham syariah terhadap menteri yang terpilih pada kabinet Indonesia Maju. Peristiwa ini diharapkan dapat membantu investor atau manajer investasi dalam menentukan strategi investasi pada saat terjadi ketidakpastian politik.

This paper aims to analyze the efficient stock market hypothesis as responsive to American Presidential Election, 2016. The meta-analysis has been done combining content analysis and event study methodology. The all major newspapers, news channels, public polls, literature and five important indices as Dow Jones Industrial Average (DJIA), NASDAQ Stock Market Composit Indexe (NASDAQ-COMP), Standard & Poor's 500 Index (SPX-500), New York Stock Exchange Composite Index (NYSE-COMP) and Other U.S Indexes-Russell 2000 (RUT-2000) are critically examined and empirically analyzed. The findings from content analysis reflect that stunned winning of Mr Trump from Republican Party worked as shock for American stock market. From event study, findings confirmed that all the major indices reflected a decline on winning of Trump and losing of Ms. Clinton from Democratic. The results are supported empirically and practically through the political event like BREXIT that resulted in shock to Global stock index and loss of $2 Trillion.

The article discusses how current mediated conditions change nature perception from a media study perspective. The article is based on different case studies such as the current sensation of atmospheric change through sensible media attached to trees which get published via Twitter, the meteorologist Amazonian Tall Tower Observatory and the use of gutta percha derived from tropical trees for the production of cables in the history of telegraphy. For analysing the examples, the perspective of »media as environments« is flipped to »environments as media«, because this focus doesn’t approach media from a networked and technological perspective primarily but makes productive the elemental character of basic »media« like air, earth and water
