Inflation means a persistent change in the price level of goods and services in an economy. It is generally measured in the consumer price index (CPI) or retail price index (RPI). Inflation reduces the purchasing power of a country's currency, as we need more units of currency over time to buy the same goods and services. The current empirical paper entitled “relationship between inflation and stock market evidence from selected global stock markets” have been undertaken with an intention to investigate the relationship between inflation and stock returns of the chosen economies. In order to realize the stated objectives, the researchers have collected the monthly data 2000 to 2017 for selected indices. In the first phase, log returns were computed and it has been tested for the existence of unit root in the distribution. In the second phase, we ran Pearson correlation coefficient for the collected data to find out the association between the inflation and stock returns. Majorit...

This study contributes to the limited established empirical research on the impact and relevance of corporate social responsibility (CSR) in the capital markets of emerging economies. We conducted an event study to demonstrate how the timing of CSR announcements by firms that have aligned their strategies to newly instituted social regulations in South Africa influenced stock prices. Using a unique dataset of publicly listed South African enterprises that undertook CSR initiatives during the ten year period from 1996 to 2005, we found that investor reactions to CSR announcements concluded during the late phase of institutional reforms are viewed positively by investors. Furthermore, CSR announcements of substantive monetary value result in significantly higher shareholder returns.

This paper considers the American put option valuation in a jump-diffusion model and relates this optimal-stopping problem to a parabolic integro-differential free-boundary problem, with special attention to the behavior of the optimal-stopping boundary. We study the regularity of the American option value and obtain in particular a decomposition of the American put option price as the sum of its counterpart European price and the early exercise premium. Compared with the Black-Scholes (BS) [5] model, this premium has an additional term due to the presence of jumps. We prove the continuity of the free boundary and also give one estimate near maturity, generalizing a recent result of Barleset al. [3] for the BS model. Finally, we study the effect of the market price of jump risk and the intensity of jumps on the American put option price and its critical stock price.

This study presents analysis of the impact of “official product” sports sponsorships with the National Football League (NFL), Major League Baseball (MLB), the National Hockey League (NHL), the National Basketball Association (NBA), and the Professional Golfers Association (PGA) on the stock prices of sponsoring firms. The primary finding of the study is that, in the main, announcements were accompanied by increases in shareholder wealth. The 53 sponsors analyzed experienced mean increases in stock valuations of about $257 million. A multiple regression analysis of firm-specific stock price changes and selected corporate and sponsorship attributes indicates that official product sponsorships with the NBA, NHL, and PGA and those with smaller market shares were associated with the largest gains in share prices. Although corporate cashflow (a proxy for agency conflicts) is statistically unrelated to shareholder approval, sponsorships by high-technology companies were associated with stronger stock price reactions than otherwise. Finally, product congruence with the sponsored sport was positively related to changes in stock prices.

Our aim is to identify common risk factors among some predetermined macroeconomic variables in a way that whether they are presented significant risk premiums in pricing equation that was given above. First we identified number of potential factors explaining returns in Turkish markets as suggested by Ross (1980) when presented APT. We found two factors were significantly explaining returns and then to find out which factor they are. we have used methodology of Chen, Roll, Ross (1986) where we have ranked portfolios according to size (market capitalization) and portfolio returns are calculated as log-returns. Our main results have showed that stock returns are exposed to systematic economic news that they are priced in accordance with their exposures. Those variables in our study are MP, DEI, BIST 100, BIST 30 and CG that must be given importance for considering their impact on stock returns.
