The purpose of this opinion piece is to discuss opportunities and challenges to physical activity [PA] research in young people. Two key limitations were identified; (i) the lack of specificity of the types of PA measured and standards in reporting this, and (ii) lack of attention given to ecological frameworks. First, it is argued that a greater specificity of measurement is needed as PA under...

This paper examines the effects of firm characteristics measured by price-to-book (PB) ratio, free cash flow (FCF), and variability of daily stock return (VDR) on investor reaction in the stock market to IT investment announcements. In contrast to previous studies, which focused exclusively on whether or not IT investment announcements led to an abnormal return in the market, this study investi...

This paper analyzes the use of announcements of objectives or intentions, announcements which are common in implementation of monetary policy. To analyze such announcements, this paper uses a model in which there is asymmetric information over the central bank’s objectives. This informational asymmetry is represented by a stochastic in‡ation target, upon which only the central bank can conditio...

These model predict that private information generated at the time of an earnings announcement (private event-peri...

We explore whether earnings announcements constitute such a dominant source using Ball and Shivakumar’s (2008) R metric: the proportion of the variation in annual returns explained by the four quarterly earnings announcement returns. We find that the earnings announce...

Abnormally high net insider selling is commonly observed after repurchase tender offer (RTO) announcements although, on average, firms experience positive abnormal returns in the years after the repurchases. We explore two potential explanations: liquidity trade timing and informed trading. Consistent with the notion that fixed price RTOs are more likely than Dutch-auction RTOs to signal underv...

Monetary authorities regularly announce targets for monetary growth, but the market may not completely trust these announcements because they may not always be truthful. Hence, the market does not have perfect knowledge about future monetary policy and must form its expectations on the basis of information it can extract from the announcements and its observations of the actual money supply. Th...
