1 5 much attention. In the field of law and economics, event studies are used to examine the effect of regulation, as well as to assess damages in legal liability cases. The number of published event studies easily exceeds 500 (see section 2), and continues to grow. A second and parallel literature, which concentrates on the methodology of event studies, began in the 1980’s. Dozens of papers have now explicitly studied statistical properties of event study methods. Both literatures are mature. From the methodology papers, much is known about how to do – and how not to do – an event study. While the profession’s thinking about event study methods has evolved over time, there seems to be relatively little controversy about statistical properties of event study methods. The conditions under which event studies provide information and permit reliable inferences are well-understood. This chapter highlights key econometric issues in event study methods, and summarizes what we know about the statistical design and the interpretation of event study experiments. Based on the theoretical and empirical findings of the methodology literature, we provide clear guidelines both for producers and consumers of event studies. Rather than provide a comprehensive survey of event study methods, we seek to sift through and synthesize existing work

Research of social impact of events is one of the emerging topics in event management literature and has a great degree of importance for a variety of different reasons considering their short term, high profile and a relatively profound effect on everyday life of local communities. (Ritchie

Generally, firms can choose among various capital structures in order to maximize overall market value of the company. It is proposed however, that
As much as market cap measures to what’s related to the company’s equity value, a firm’s decision based on its capital structure estimates more significantly to how the value of that company is allocated not only for the return on equity but accounting for debt as well. Most economists would refer to capital structure as the mix of a company’s long-term debt, the current portion of it, and of common and preferred stock. Furthermore, large tech-companies today have been taking advantage of capital structure optimizations as it is placed shoulder to shoulder to increasing return on equity thus lowering weighted average costs of capital for long-term investment. In other words, it is how a corporate manager should base his/her decisions on financing the company’s assets and operations through various growth prospects and forecast estimates. We will begin to further evaluate the composition of Google’s capital structure by focusing on the company’s key statistics and research data from the selected top online providers of financial statements, including Google!
The weak-form efficiency cannot explain January effect. In semi-strong-form efficient market, to test this hypothesis, researchers look at the adjustment of share prices to public announcements such as earnings and dividend announcements, splits, takeovers and repurchases. As time goes, later tests tend to be not supportive to EMH. For instance, semi-strong-form efficiency cannot explain the pricing/earning effect. In strong-form efficiency, the highest level of market efficiency, Fama (1991) pointed out the immeasurability of market efficiency and suggested that it must be tested jointly with an equilibrium model of expected. However, perfect efficiency is an unrealistic benchmark that is unlikely to hold in practice.

Already in 1958, Modigliani and Miller have pointed the discussion of capital structure towards the cost of debt and equity. According to their first proposition, in a world of no corporate taxes and with perfect markets, financial leverage has no effect on a firm’s value. In their second proposition, they state that the cost of equity equals a linear function defined by the required return on assets and the cost of debt (Modigliani and Miller, 1958).

The purpose of this assignment is to study the finance sources available to a company. Here according to the assignment requirement, we have to select a British public company to study the available sources of finance from where the firm collects its capital requirement. Following the guidelines we have to analyze various sources with their potentiality and then we make viable analysis of Cash and sales budget. Here some salient financial ratios are employed for the purpose of analyzing the financial statement of the company.
