Financial economics Wikipedia. Financial economics 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. Its concern is thus the interrelation of financial variables, such as prices, interest rates and shares, as opposed to those concerning the real economy. It has two main areas of focus 2asset pricing or investment theory and corporate finance the first being the perspective of providers of capital and the second of users of capital. The subject is concerned with the allocation and deployment of economic resources, both spatially and across time, in an uncertain environment. It therefore centers on decision making under uncertainty in the context of the financial markets, and the resultant economic and financial models and principles, and is concerned with deriving testable or policy implications from acceptable assumptions. It is built on the foundations of microeconomics and decision theory. Financial econometrics is the branch of financial economics that uses econometric techniques to parameterise these relationships. Mathematical finance is related in that it will derive and extend the mathematical or numerical models suggested by financial economics. Financial economics is the branch of economics characterized by a concentration on monetary activities, in which money of one type or another is likely to appear. Note though that the emphasis there is mathematical consistency, as opposed to compatibility with economic theory. Financial economics is usually taught at the postgraduate level see Master of Financial Economics. Recently, specialist undergraduate degrees are offered in the discipline. Note that this article provides an overview and survey of the field for derivations and more technical discussion, see the specific articles linked. Underlying economicseditAs above, the discipline essentially explores how rational investors would apply decision theory to the problem of investment.

Present value, expectation and utilityeditUnderlying all of financial economics are the concepts of present value and expectation. Calculating their present value allows the decision maker to aggregate the cashflows or other returns to be produced by the asset in the future, to a single value at the date in question, and to thus more readily compare two opportunities this concept is therefore the starting point for financial decision making. Its history is correspondingly early Richard Witt discusses compound interest in depth already in 1. Udp 53 Vpn. Arithmeticall Questions 7 further developed by Johan de Witt and Edmond Halley. An immediate extension is to combine probabilities with present value, leading to the expected value criterion which sets asset value as a function of the sizes of the expected payouts and the probabilities of their occurrence. These ideas originate with Blaise Pascal and Pierre de Fermat. This decision method, however, fails to consider risk aversion as any student of finance knows6. In other words, since individuals receive greater utility from an extra dollar when they are poor and less utility when comparatively rich, the approach is to therefore adjust the weight assigned to the various outcomes states correspondingly. Some investors may in fact be risk seeking as opposed to risk averse, but the same logic would apply. Choice under uncertainty here, may then be characterized as the maximization of expected utility. More formally, the resulting expected utility hypothesis states that, if certain axioms are satisfied, the subjective value associated with a gamble by an individual is that individuals statistical expectation of the valuations of the outcomes of that gamble. The impetus for these ideas arise from various inconsistencies observed under the expected value framework, such as the St. Petersburg paradox see also Ellsberg paradox. The development here originally due to Daniel Bernoulli, and later formalized by John von Neumann and Oskar Morgenstern. Arbitrage free pricing and equilibriumeditThe concepts of arbitrage free, rational, pricing and equilibrium are then coupled with the above to derive classical8 or neo classical9 financial economics. Rational pricing is the assumption that asset prices and hence asset pricing models will reflect the arbitrage free price of the asset, as any deviation from this price will be arbitraged away. This assumption is useful in pricing fixed income securities, particularly bonds, and is fundamental to the pricing of derivative instruments.

Economic equilibrium is, in general, a state in which economic forces such as supply and demand are balanced, and, in the absence of external influences these equilibrium values of economic variables will not change. General equilibrium deals with the behavior of supply, demand, and prices in a whole economy with several or many interacting markets, by seeking to prove that a set of prices exists that will result in an overall equilibrium. This is in contrast to partial equilibrium, which only analyzes single markets. The two concepts are linked as follows where market prices do not allow for profitable arbitrage, i. Intuitively, this may be seen by considering that where an arbitrage opportunity does exist, then prices can be expected to change, and are therefore not in equilibrium. An arbitrage equilibrium is thus a precondition for a general economic equilibrium. The immediate, and formal, extension of this idea, the Fundamental theorem of asset pricing, shows that where markets are as aboveand are additionally implicitly and correspondingly completeone may then make financial decisions by constructing a risk neutral probability measure corresponding to the market. Complete here means that there is a price for every asset in every possible state of the world, and that the complete set of possible bets on future states of the world can therefore be constructed with existing assets assuming no friction, essentially solving simultaneously for n probabilities, given n prices. The formal derivation will proceed by arbitrage arguments. For a worked example see Rational pricingRisk neutral valuation, where, in a simplified environment, the economy has only two possible statesup and downand where p and 1p are the two corresponding i. With this measure in place, the expected, i. All pricing models are then essentially variants of this, given specific assumptions andor conditions. This approach is consistent with the above, but with the expectation based on the market i. Thus, continuing the example, to value a specific security, its forecasted cashflows in the up and down states are multiplied through by p and 1 p respectively, and are then discounted at the risk free interest rate plus an appropriate premium. In general, this premium may be derived by the CAPM or extensions as will be seen under Uncertainty. State priceseditWith the above relationship established, the further specialized ArrowDebreu model may be derived. This important result suggests that, under certain economic conditions, there must be a set of prices such that aggregate supplies will equal aggregate demands for every commodity in the economy. The analysis here is often undertaken assuming a Representative agent. APA Referencing guide University of Southern Queensland.

The authors surname is placed first, followed by initials or first name, and then the year of publication is given.
