About this Textbook This textbook is an elementary introduction to the key topics in mathematical finance and financial economics - two realms of ideas that substantially overlap but are often treated separately from each other.

Where factors additional to volatility are considered kurtosis, skew The universal portfolio algorithm Thomas M. Cover applies machine learning to asset selection, learning adaptively from historical data. Behavioral portfolio theory recognizes that investors have varied aims and create an investment portfolio that meets a broad range of goals.

Copulas have lately been applied here. As regards derivative pricing, the binomial options pricing model provides a discretized version of Black—Scholes, useful for the valuation of American styled options.

Discretized models of this type are built—at least implicitly—using state-prices as above ; relatedly, a large number of researchers have used options to extract state-prices for a variety of other applications in financial economics. Various other numeric techniques have also been developed. The theoretical framework too has been extended such that martingale pricing is now the standard approach.

Drawing on these techniques, derivative models for various other underlyings and applications have also been developed, all based off the same logic using " contingent claim analysis ".

Exotic derivatives are now routinely valued. Multi-asset underlyers are handled via simulation or copula based analysis. Similarly, beginning with Oldrich Vasicek , various short rate models , as well as the HJM and BGM forward rate -based techniques, allow for an extension of these techniques to fixed income- and interest rate derivatives.

The Vasicek and CIR models are equilibrium-based, while Ho—Lee and subsequent models are based on arbitrage-free pricing. Bond valuation is relatedly extended: As above, OTC derivative pricing has relied on the BSM risk neutral pricing framework, under the assumptions of funding at the risk free rate and the ability to perfectly replicate cashflows so as to fully hedge.

This, in turn, is built on the assumption of a credit-risk-free environment. Post the financial crisis of , therefore, issues such as counterparty credit risk , funding costs and costs of capital are additionally considered, [26] and a Credit Valuation Adjustment , or CVA—and potentially other valuation adjustments , collectively xVA —is generally added to the risk-neutral derivative value.

This is because post-crisis, OIS is considered a better proxy for the "risk-free rate". Swap pricing - and, in fact, curve construction - is further modified: Corporate finance theory has also been extended: As discussed, Monte Carlo methods in finance , introduced by David B. Relatedly, Real Options theory allows for owner—i. More traditionally, decision trees —which are complementary—have been used to evaluate projects, by incorporating in the valuation all possible events or states and consequent management decisions ; [30] [28] the correct discount rate here reflecting each point's "non-diversifiable risk looking forward.

## LeRoy S., Werner J. Principles of financial economics

Related to this, is the treatment of forecasted cashflows in equity valuation. In more modern treatments, then, it is the expected cashflows in the mathematical sense combined into an overall value per forecast period which are discounted.

Other developments here include [36] agency theory , which analyses the difficulties in motivating corporate management the "agent" to act in the best interests of shareholders the "principal" , rather than in their own interests. Clean surplus accounting and the related residual income valuation provide a model that returns price as a function of earnings, expected returns, and change in book value , as opposed to dividends.

The typical application of real options is to capital budgeting type problems as described. However, they are also applied to questions of capital structure and dividend policy , and to the related design of corporate securities; [37] and since stockholder and bondholders have different objective functions, in the analysis of the related agency problems. For example, convertible bonds can must be priced consistent with the state-prices of the corporate's equity.

As above, there is a very close link between i the random walk hypothesis , with the associated expectation that price changes should follow a normal distribution , on the one hand, and ii market efficiency and rational expectations , on the other.

Note, however, that wide departures from these are commonly observed, and there are thus, respectively, two main sets of challenges.

Empirical evidence, however, suggests that these assumptions may not hold see Kurtosis risk , Skewness risk , Long tail and that in practice, traders, analysts and risk managers frequently modify the "standard models" see Model risk.

Financial models with long-tailed distributions and volatility clustering have been introduced to overcome problems with the realism of the above "classical" financial models; while jump diffusion models allow for option pricing incorporating "jumps" in the spot price. Portfolio managers, likewise, have modified their optimization criteria and algorithms; see Portfolio theory above. Closely related is the volatility smile , where implied volatility —the volatility corresponding to the BSM price—is observed to differ as a function of strike price i.

The term structure of volatility describes how implied volatility differs for related options with different maturities. An implied volatility surface is then a three-dimensional surface plot of volatility smile and term structure. In consequence traders and risk managers use "smile-consistent" models, firstly, when valuing derivatives not directly mapped to the surface, facilitating the pricing of other, i.

The two main approaches are local volatility and stochastic volatility. In this way calculated prices — and numeric structures — are market-consistent in an arbitrage-free sense. The second approach assumes that the volatility of the underlying price is a stochastic process rather than a constant.

This approach addresses certain problems identified with hedging under local volatility. Related to local volatility are the lattice -based implied-binomial and -trinomial trees — essentially a discretization of the approach — which are similarly used for pricing; these are built on state-prices recovered from the surface.

Edgeworth binomial trees allow for a specified i. As above, additional to log-normality in returns, BSM—and, typically, other derivative models—assume d the ability to perfectly replicate cashflows so as to fully hedge, and hence to discount at the risk-free rate.

## The Choice: Embrace the Possible

Post crisis, then, various x-value adjustments are made to the risk-neutral derivative value. Note that these are additional to any smile or surface effect: Also, were this not the case, then each counterparty would have its own surface As seen, a common assumption is that financial decision makers act rationally; see Homo economicus. Recently, however, researchers in experimental economics and experimental finance have challenged this assumption empirically.

These assumptions are also challenged theoretically , by behavioral finance , a discipline primarily concerned with the limits to rationality of economic agents. Related to these are various of the economic puzzles , concerning phenomena similarly contradicting the theory.

The equity premium puzzle , as one example, arises in that the difference between the observed returns on stocks as compared to government bonds is consistently higher than the risk premium rational equity investors should demand, an " abnormal return ".

More generally, and particularly following the financial crisis of — , financial economics and mathematical finance have been subjected to deeper criticism; notable here is Nassim Nicholas Taleb , who claims that the prices of financial assets cannot be characterized by the simple models currently in use, rendering much of current practice at best irrelevant, and, at worst, dangerously misleading; see Black swan theory , Taleb distribution.

A topic of general interest studied in recent years has thus been financial crises , [43] and the failure of financial economics to model these. A related problem is systemic risk: Areas of research attempting to explain or at least model these phenomena, and crises, include [12] noise trading , market microstructure , and Heterogeneous agent models.

The latter is extended to agent-based computational economics , where price is treated as an emergent phenomenon , resulting from the interaction of the various market participants agents. The noisy market hypothesis argues that prices can be influenced by speculators and momentum traders , as well as by insiders and institutions that often buy and sell stocks for reasons unrelated to fundamental value ; see Noise economic.

The adaptive market hypothesis is an attempt to reconcile the efficient market hypothesis with behavioral economics, by applying the principles of evolution to financial interactions. An information cascade , alternatively, shows market participants engaging in the same acts as others " herd behavior " , despite contradictions with their private information. Copula-based modelling has similarly been applied. On the obverse, however, various studies have shown that despite these departures from efficiency, asset prices do typically exhibit a random walk and that one cannot therefore consistently outperform market averages "alpha".

See also John C. Note also that institutionally inherent limits to arbitrage —as opposed to factors directly contradictory to the theory—are sometimes proposed as an explanation for these departures from efficiency. From Wikipedia, the free encyclopedia.
