    Examining the Long Term Relationship Between Crude Oil and Food Commodity Prices: Co-integration and Causality
    (JEMS, 2011-08-15) Ibrahim Awad; Ghaith, Ziad
    Recently a new debate has started regarding food and energy issues because food has become an alternative source of energy and energy becoming the main input of agriculture. However, this study attempts to investigate the possible long-term relationship between the prices of crude oil and food commodities represented by maize, wheat, sorghum, soybean, barley, linseed oil, soybean oil, and palm oil. Time series econometric techniques (Unit root tests, Co-integration, and Granger causality) were applied. The study utilizes monthly data over the period of 1980 to 2009. The results of this study reveal that there is a strong evidence of long-term relationship between crude oil and the food commodities prices. A traditional Granger Causality is used to check whether causality exists between two product prices. The outcome suggests that there is unidirectional causality between the prices crude oil and some of the food commodities under examination.

    The Intrinsic & Market Value of the Common Stocks: Evidence from Palestine Exchange
    (Center for Research Promotion, 2012-12-04) Awad, Ibrahim M.; Murrar, Abdullah; Ayyad, Hind
    In analogues way to the sayings “What goes around comes around” the market price of the company stock’s is closely related to its performance, the more optimistic, the more the investors will be and hence willing to pay a higher price for the company's share and vice versa. Seamlessly, given that the goal of the firms is to maximize the value of the shareholders, the more the intrinsic value of the company stock, the more market value of the stock price, so that there is a positive correlation between the intrinsic and market value of a particular common stock. This is founded in the first test of this study. Ironically, the positive correlation does not always imply that the intrinsic value causes the changes in market value; that is, empirical results of the co-integration test of this paper reveals that the market value is what causes the changes in intrinsic value, meaning that stock prices in Palestine Exchange does not significantly depend on fundamentals, but rather on supply and demand forces, other things being equal.

    Toward Efficient Management of Working Capital: The case of the Palestinian Exchange
    (International Scientific Press, 2012-02-28) Awad, Ibrahim M.; Al-Ewesat, Abdel-Rahman
    The importance of this study comes from the truth that financial statements' users need reliable, relevant, and useful financial information that should be reflected in stock prices. However, this study aims at investigating current ratio, receivables turnover, inventory turnover, and earnings per share for 18 companies listed on PEX over the period from 2006 to 2011. Regression analysis and econometric techniques of Unit root test, Co-integration, and Granger causality are applied. The study outcomes indicate that stock prices of companies listed on PEX are affected by working capital components. The results of traditional Granger Causality reveal that there is no causal relationship between stock prices and working capital components. In addition, there is a positive relationship between CR and EPS and stock prices whereas there is a negative relationship between RT and IT. The paper concludes that cash, times of receivables collection and inventory turnover are necessary to be taken into account by both investors and companies for improved the management of working capital at the PEX.
