Earnings Response Coefficient
In financial economics, finance, and accounting, the earnings response coefficient, or ERC, is the estimated relationship between equity returns and the unexpected portion of (i.e., new information in) companies' earnings announcements. Development Arbitrage pricing theory describes the theoretical relationship between information that is known to market participants about a particular equity (e.g., a common stock share of a particular company) and the price of that equity. Under the strong form of the efficient market hypothesis, equity prices are expected in the aggregate to reflect all relevant information at a given time. Market participants with superior information are expected to exploit that information until share prices have effectively impounded the information. Therefore, in the aggregate, a portion of changes in a company's share price is expected to result from changes in the relevant information available to the market. The ERC is an estimate of the change in a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Financial Economics
Financial economics, also known as finance, is the branch of economics characterized by a "concentration on monetary activities", in which "money of one type or another is likely to appear on ''both sides'' of a trade".William F. Sharpe"Financial Economics", in Its concern is thus the interrelation of financial variables, such as share prices, interest rates and exchange rates, as opposed to those concerning the real economy. It has two main areas of focus: Merton H. Miller, (1999). The History of Finance: An Eyewitness Account, ''Journal of Portfolio Management''. Summer 1999. asset pricing, commonly known as "Investments", and corporate finance; the first being the perspective of providers of capital, i.e. investors, and the second of users of capital. It thus provides the theoretical underpinning for much of finance. The subject is concerned with "the allocation and deployment of economic resources, both spatially and across time, in an uncertain environment".See Fama and ...

Nonlinear Regression
In statistics, nonlinear regression is a form of regression analysis in which observational data are modeled by a function which is a nonlinear combination of the model parameters and depends on one or more independent variables. The data are fitted by a method of successive approximations. General In nonlinear regression, a statistical model of the form, : \mathbf \sim f(\mathbf, \boldsymbol\beta) relates a vector of independent variables, \mathbf, and its associated observed dependent variables, \mathbf. The function f is nonlinear in the components of the vector of parameters \beta, but otherwise arbitrary. For example, the Michaelis–Menten model for enzyme kinetics has two parameters and one independent variable, related by f by: : f(x,\boldsymbol\beta)= \frac This function is nonlinear because it cannot be expressed as a linear combination of the two ''\beta''s. Systematic error may be present in the independent variables but its treatment is outside the scope of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finance Theories
Finance is the study and discipline of money, currency and capital assets. It is related to, but not synonymous with economics, the study of production, distribution, and consumption of money, assets, goods and services (the discipline of financial economics bridges the two). Finance activities take place in financial systems at various scopes, thus the field can be roughly divided into personal, corporate, and public finance. In a financial system, assets are bought, sold, or traded as financial instruments, such as currencies, loans, bonds, shares, stocks, options, futures, etc. Assets can also be banked, invested, and insured to maximize value and minimize loss. In practice, risks are always present in any financial action and entities. A broad range of subfields within finance exist due to its wide scope. Asset, money, risk and investment management aim to maximize value and minimize volatility. Financial analysis is viability, stability, and profitability assessmen ...

Accounting Research
Accounting research examines how accounting is used by individuals, organizations and government as well as the consequences that these practices have. Starting from the assumption that accounting both measures and makes visible certain economic events, accounting research has studied the roles of accounting in organizations and society and the consequences that these practices have for individuals, organizations, governments and capital markets. It encompasses a broad range of topics including financial accounting research, management accounting research, auditing research, capital market research, accountability research, social responsibility research and taxation research.Oler, Derek K., Mitchell J. Oler, and Christopher J. Skousen. 2010. "Characterizing Accounting Research." ''Accounting Horizons'' 24 (4): 635–670. Academic accounting research "addresses all aspects of the accounting profession" using the scientific method, while research by practicing accountants focuses ...

Roger C
Roger is a given name, usually masculine, and a surname. The given name is derived from the Old French personal names ' and '. These names are of Germanic origin, derived from the elements ', ''χrōþi'' ("fame", "renown", "honour") and ', ' ("spear", "lance") (Hrōþigēraz). The name was introduced into England by the Normans. In Normandy, the Frankish name had been reinforced by the Old Norse cognate '. The name introduced into England replaced the Old English cognate '. ''Roger'' became a very common given name during the Middle Ages. A variant form of the given name ''Roger'' that is closer to the name's origin is ''Rodger''. Slang and other uses Roger is also a short version of the term "Jolly Roger", which refers to a black flag with a white skull and crossbones, formerly used by sea pirates since as early as 1723. From up to , Roger was slang for the word "penis". In ''Under Milk Wood'', Dylan Thomas writes "jolly, rodgered" suggesting both the sexual double entend ...

Clean Surplus Accounting
The clean surplus accounting method provides elements of a forecasting model that yields price as a function of earnings, expected returns, and change in book value. Ohlson, J. A. (1995)"Earnings, Book Values and Dividends in Equity Valuation" Contemporary Accounting Research, 11 (Spring), 1995. Ohlson and Feltham, (1995"Valuation and Clean Surplus Accounting for Operating and Financial Activities" ''Contemporary accounting research'' Frankel, R., & Lee, C. M. (1998) Journal of Accounting and economics, 25(3), 283-319. The theory's primary use is to estimate the value of a company’s shares (instead of discounted dividend/cash flow approaches). The secondary use is to estimate the cost of capital, as an alternative to e.g. the CAPM. The "clean surplus" is calculated by not including transactions with shareholders (such as dividends, share repurchases or share offerings) when calculating returns; whereas standard accounting for financial statements requires that the change i ...

Capital Asset Pricing Model
In finance, the capital asset pricing model (CAPM) is a model used to determine a theoretically appropriate required rate of return of an asset, to make decisions about adding assets to a well-diversified portfolio. The model takes into account the asset's sensitivity to non-diversifiable risk (also known as systematic risk or market risk), often represented by the quantity beta (β) in the financial industry, as well as the expected return of the market and the expected return of a theoretical risk-free asset. CAPM assumes a particular form of utility functions (in which only first and second moments matter, that is risk is measured by variance, for example a quadratic utility) or alternatively asset returns whose probability distributions are completely described by the first two moments (for example, the normal distribution) and zero transaction costs (necessary for diversification to get rid of all idiosyncratic risk). Under these conditions, CAPM shows that the cost of eq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linear Equation
In mathematics, a linear equation is an equation that may be put in the form a_1x_1+\ldots+a_nx_n+b=0, where x_1,\ldots,x_n are the variables (or unknowns), and b,a_1,\ldots,a_n are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation, and may be arbitrary expressions, provided they do not contain any of the variables. To yield a meaningful equation, the coefficients a_1, \ldots, a_n are required to not all be zero. Alternatively, a linear equation can be obtained by equating to zero a linear polynomial over some field, from which the coefficients are taken. The solutions of such an equation are the values that, when substituted for the unknowns, make the equality true. In the case of just one variable, there is exactly one solution (provided that a_1\ne 0). Often, the term ''linear equation'' refers implicitly to this particular case, in which the variable is sensibly called the ''unknown''. In the case of two vari ...

Financial Accounting
Financial accounting is the field of accounting concerned with the summary, analysis and reporting of financial transactions related to a business. This involves the preparation of financial statements available for public use. Stockholders, suppliers, banks, employees, government agencies, business owners, and other stakeholders are examples of people interested in receiving such information for decision making purposes. Financial accountancy is governed by both local and international accounting standards. Generally Accepted Accounting Principles (GAAP) is the standard framework of guidelines for financial accounting used in any given jurisdiction. It includes the standards, conventions and rules that accountants follow in recording and summarizing and in the preparation of financial statements. On the other hand, International Financial Reporting Standards (IFRS) is a set of accounting standards stating how particular types of transactions and other events should be repo ...

Positive Accounting
Positive accounting is the branch of academic accounting research that seeks to explain and predict actual accounting practices. This contrasts with normative accounting, that seeks to derive and prescribe "optimal" accounting standards. Background Positive accounting emerged with empirical studies that proliferated in accounting in the late 1960s. It was organized as an academic school of thought of discipline by the work of Ross Watts and Jerold Zimmerman (in 1978 and 1986) at the William E. Simon School of Business Administration at the University of Rochester, and by the founding of thJournal of Accounting and Economicsin 1979. When published, the pioneering articles were greeted with considerable criticism. Views Positive accounting can be associated with the contractual view of the firm. The firm is viewed as “a nexus of contracts” and accounting one tool to facilitate the formation and performance of contracts. Under this view, accounting practices evolve to mi ...
