The market consisting of a stock evolving to a jump-diffusion model and a riskless bond is incomplete. In an incomplete market an option does not have a unique price. When changing measure in a jump-diffusion world, we can change the drift, the intensity of the jumps and the jump distribution but we cannot change the volatility of the underlying. 386 Incomplete markets and jump-diffusion processes Increasing jump-intensity always increases the price of a European option, which has a convex final payoff. For a digital option increasing jump-intensity can either increase or decrease the price of an option. In an incomplete market it is the market which chooses the measure.

…

Our hedging argument has shown that only prices between zero and five can be non-arbitrageable, whilst the risk-neutral argument shows that prices between zero and five are not arbitrageable. We therefore conclude that the set of arbitrage-free prices for the option is the set of prices between zero and five. The three-world universe is an example of an incomplete market, that is, a market where portfolios cannot be arranged to give precisely the desired pay-off, and it is characteristic of incomplete markets that the price of an option can only be shown to lie in an interval rather than being forced to take a precise value. The market price of such an option would then be determined within the range of possible prices by the risk-preferences of traders in the market rather than mathematics

…

The bank can still make money by selling put options but it is doing so by taking on risk, rather than by charging for the cost of hedging, as in the Black-Scholes framework. The purchase of the put option is therefore a transference of risk from the fund manager to the bank. The market price will settle on a point where the 361 362 Incomplete markets and jump-diffusion processes banks feel that they are being adequately compensated for taking on the extra risk. A major determinant of the price is therefore risk preferences rather than arbitrage. Once we have moved to an incomplete market, there are two different issues to be addressed. The first is how to use arbitrage to bound the prices of vanilla options. The second is to determine prices for exotic options which are compatible with both the model and the prices of the vanilla options traded in the market.

Since w*(·) is a Wiener process under the corresponding measure P* for any η, then the distribution of S(·) is the same under all these P*. In other words, all these measures coincide on In addition, note that theoretical problems also arise for the case of random r. 5.11.2 Pricing for an incomplete market Mean-variance hedging Similarly to the case of the discrete time market, Definition 5.43 leads to superreplication for incomplete markets. Clearly, it is not always meaningful. Therefore, there is another popular approach for an incomplete market. Definition 5.65 (mean-variance hedging). The fair price of the option is the initial wealth X(0) such E|X(T)−ψ|2 is minimal over all admissible self-financing strategies.

…

Find the fair price of the option with payoff ψ=max(ST−1, 0). Solution. We have Problem 3.54 Consider the Cox-Ross-Rubinstein model such that ξt=±ε, Bt=1.1Bt−1, S0=1, ε=1/4, T=2. Find the fair price of the option with payoff F(S1,…, ST)=max(ST−1, 0). Solution. We have For incomplete markets, Definition 3.49 leads to super-replication. That is not always meaningful. Therefore, there is another popular approach for incomplete markets. Definition 3.55 (mean-variance hedging). The fair price of the option is the initial wealth X0 such that E|XT−ψ|2 is minimal over all admissible self-financing strategies. © 2007 Nikolai Dokuchaev Discrete Time Market Models 41 In many cases, this definition leads to the option price calculated as the expectation under a risk-neutral equivalent measure which needs to be chosen by some optimal way, since a risk-neutral equivalent measure is not unique for an incomplete market. 3.11 Increasing frequency and continuous time limit In reality, prices may change and be measured very frequently.

…

In many cases, this definition leads to the option price e−rTE*ψ, where E* is the expectation for a risk-neutral equivalent measure that needs to be chosen by some optimal way, since this measure is not unique for an incomplete market. This measure needs to be found via solution of an optimization problem. In fact, this method is the latest big step in the development of modern pricing theory. It requires some additional non-trivial analysis outside of our course. Completion of the market Sometimes it is possible to make an incomplete market model complete by adding new assets. For instance, if σ(t) is random and evolves as the solution of an Ito equation driven by a new Wiener process W(t) then the market can be made complete by allowing trading of any option on this stock (say, European call with given strike price).

Oxford Science Publications Lewis, A Series of articles in Wilmott magazine September 2002 to August 2004 Merton, RC 1976 Option pricing when underlying stock returns are discontinuous. Journal of Financial Economics 3 125-44 What is Meant by “Complete” and “Incomplete” Markets? Short Answer A complete market is one in which a derivative product can be artificially made from more basic instruments, such as cash and the underlying asset. This usually involves dynamically rebalancing a portfolio of the simpler instruments, according to some formula or algorithm, to replicate the more complicated product, the derivative. Obviously, an incomplete market is one in which you can’t replicate the option with simpler instruments. Example The classic example is replicating an equity option, a call, say, by continuously buying or selling the equity so that you always hold the amountΔ = e−D(T −t)N (d1), in the stock, where and Long Answer A slightly more mathematical, yet still quite easily understood, description is to say that a complete market is one for which there exist the same number of linearly independent securities as there are states of the world in the future.

…

People can therefore disagree on the probability of a stock rising or falling but still agree on the value of an option, as long as they share the same view on the stock’s volatility. In probabilistic terms we say that in a complete market there exists a unique martingale measure, but for an incomplete market there is no unique martingale measure. The interpretation of this is that even though options are risky instruments we don’t have to specify our own degree of risk aversion in order to price them. Enough of complete markets, where can we find incomplete markets? The answer is ‘everywhere.’ In practice, all markets are incomplete because of real-world effects that violate the assumptions of the simple models. Take volatility as an example.

…

In reality, we don’t know what volatility will be in the future so markets are incomplete. We also get incomplete markets if the underlying follows a jump-diffusion process. Again more possible states than there are underlying securities. Another common reason for getting incompleteness is if the underlying or one of the variables governing the behaviour of the underlying is random. Options on terrorist acts cannot be hedged since terrorist acts aren’t traded (to my knowledge at least). We still have to price contracts even in incomplete markets, so what can we do? There are two main ideas here. One is to price the actuarial way, the other is to try to make all option prices consistent with each other.

Unfortunately, contrary to intuition, the no-arbitrage condition is not enough machinery to uniquely price derivative securities. That is, no-arbitrage is not a sufficient condition for uniquely pricing derivative securities. There are generally many linear, positive pricing mechanisms, all consistent with no-arbitrage, for non-replicable financial claims! Another way to say this is that in an incomplete market, there can be many equally valid (no-arbitrage) pricing mechanisms. We already have an inkling of this through our study of ROP. Rational option pricing, which is exclusively based on the foundation of the no-arbitrage principle, produces pricing relationships (such as European Put-Call Parity) and pricing bounds or ranges into which rational option prices must fall.

…

There is no immediate and completely adequate empirical fix for the constant σ assumption, except to throw out Black–Scholes’ assumption of a stationary log-normal diffusion, and search for a viable (smile-consistent) underlying stochastic process among the vast set of alternatives, many of which will lead to incomplete markets. Black–Scholes and its modifications, however, still have tremendous appeal, especially among traders, who use Black–Scholes calibrated to an implied volatility surface. Traders use ATM options to imply volatility, since these are the most liquid, and therefore most informative about future volatility.

…

Because the non-hedgeable risks are precisely those that cannot be diversified away (hedged out) by attempting to replicate the contingent claim, they would command risk premia in the contingent claim price. These would, of necessity, show up in arbitrage-free pricing formulas for the contingent claim. This also renders such contingent claim prices not preference-free. We can summarize this as follows. In incomplete markets, non-replicable claims could be priced in a manner that is arbitrage-free (EMMs exist), and yet not preference-free. Furthermore, there would be multiple arbitrage-free, non-preference-free valuations of non-replicable claims. We know this is true, because FTAP2 tells us that a claim is replicable if and only if there is a unique EMM for the discounted price process.

SOME BASIC THEORY OF FINANCE While it is not too diﬃcult to solve this system in this case one can see that with more branches and more derivatives, this non-linear system of equations becomes diﬃcult very quickly. What do we do if we observe market prices for only two derivatives defined on this stock, and only two parameters can be obtained from the market information? This is an example of what is called an incomplete market, a market in which the risk neutral distribution is not uniquely specified by market information. In general when we have fewer equations than parameters in a model, there are really only two choices (a) Simplify the model so that the number of unknown parameters and the number of equations match.

…

SOME BASIC THEORY OF FINANCE Theorem 9 shows that this exponentially tilted distribution has the property of being the closest to the original measure P while satisfying the condition that the normalized sequence of stock prices forms a martingale. There is a considerable literature exploring the links between entropy and risk-neutral valuation of derivatives. See for example Gerber and Shiu (1994), Avellaneda et. al (1997), Gulko(1998), Samperi (1998). In a complete or incomplete market, risk-neutral valuation may be carried out using a martingale measure which maximizes entropy or minimizes cross-entropy subject to some natural constraints including the martingale constraint. For example it is easy to show that when interest rates r are constant, Q is the risk-neutral measure for pricing derivatives on a stock with stock price process St , t = 0, 1, ... if and only if it is the probability measure minimizing H(Q, P ) subject to the martingale constraint 1 St+1 ]. 1̄ + r St = EQ [ (2.23) There is a continuous time analogue of (2.22) as well which we can anticipate by inspecting the form of the solution.

PRICING STATE-CONTINGENT CLAIMS Theorem 5.4.1 If there are M complex securities (M = N ) and the payoff matrix Y is non-singular, then markets are complete. Proof Suppose the optimal trade for consumer i state j is xij − eij . Then can invert Y to work out optimal trades in terms of complex securities. Q.E.D. An (N + 1)st security would be redundant. Either a singular square matrix or < N complex securities would lead to incomplete markets. So far, we have made no assumptions about the form of the utility function, written purely as u (x0 , x1 , x2 , . . . , xN ) , where x0 represents the quantity consumed at date 0 and xi (i > 0) represents the quantity consumed at date 1 if state i materialises. 5.4.1 Completion of markets using options Assume that there exists a state index portfolio, Y , yielding different non-zero payoffs in each state (i.e. a portfolio with a different payout in each state of nature, possibly one mimicking aggregate consumption).

Bruce Greenwald and Joseph Stiglitz importantly extended the same overall line of argument in their paper ‘Externalities in Economies with Imperfect Information and Incomplete Markets’, Quarterly Journal of Economics, 101.2, 1986. This showed that the effect of imperfect information was to break the link between equilibrium models and any presumption of efficiency. The formal conditions of market failure were thus all but inevitable in any real-world situation, with imperfect information, incomplete markets and a host of other frictional factors at work. In such cases—that is, in virtually every case—policy interventions could in principle be made that generated improvements in welfare.

The circumstances that they identified where markets did not lead to efficiency were called market failures. Subsequently, Greenwald and Stiglitz showed that whenever information was imperfect and markets incomplete—essentially always—markets were not efficient (“Externalities in Economies with Imperfect Information and Incomplete Markets”). Of course, even earlier, Keynes had emphasized that markets do not by themselves maintain full employment. 34 See James Edward Meade, The Theory of International Economic Policy, vol. 2, Trade and Welfare (London: Oxford University Press, 1955); and Richard G.

The nearest we have got to this is perhaps the European Union – or, more specifically, the 19 members that make up the Eurozone. Yet the single currency project is only half-finished – and arguably only half-baked. The Eurozone has some aspects of nationhood: a single currency, a single monetary policy, a single (although incomplete) market and, for those who also happen to be members of Schengen, a common external border. Yet it lacks other aspects: there is no common fiscal policy and no common border force; the European Parliament is a weak and distant institution; and a common European defence policy has so far proved be more a matter of words than deeds.

Imperfections can arise for various reasons: the unwillingness of private firms to invest in areas, like basic research, from which they cannot appropriate private profits because the results are a ‘public good’ accessible to all firms (results of basic R&D as a positive externality); the fact that private firms do not factor in the cost of their pollution in setting prices (pollution as a negative externality); or the fact that the risk of certain investments is too high for any one firm to bear them all alone (leading to incomplete markets). Given these different forms of market failure, examples of the expected role of the State would include publicly funded basic research, taxes levied on polluting firms and public funding for infrastructure projects. While this framework is useful, it cannot explain the ‘visionary’ strategic role that government has played in making these investments.

For some reason, the economics of market failure has received a lot less attention than the economics of market success. Perhaps the word “failure” has such negative connotations that it offends the American psyche. For whatever reason, “market failure economics” never took off as a catchphrase. Some textbooks refer to the “economics of information,” or the “economics of incomplete markets.” Recently, the term “behavioral economics” has come into vogue. For myself, I prefer the phrase “reality-based economics,” which is the title of Part II. Reality-based economics is less unified than utopian economics: because the modern economy is labyrinthine and complicated, it encompasses many different theories, each applying to a particular market failure.

For ﬁxed τ ∈ S, we consider the utility maximization problem Vτ (x) sup (π ,C )∈ τ (x) J (x; π, C, τ ). (11.25) 301 11.6 Duality Approach Not allowing our agent to invest in the stock market (π(τ ,T ] ≡ 0) after retirement, creates an incomplete market in which the problem is difﬁcult to solve explicitly. However, under the additional Assumption (11.1) that the interest rate is locked after retirement, we can solve the optimization problem after retirement explicitly by pathwise optimization given the information available at retirement time Fτ .

in the financial crisis. 23 The pretence that every important macroeconomic issue could be explained in terms of a single model was a major error. Radical uncertainty and non-stationarity go hand in hand. There is no stable structure of the world about which we could learn from past experience and use to extrapolate future behaviour. We live in a world of incomplete markets in which there are simply no price signals to guide us back to an efficient equilibrium. There are times when expectations have a life of their own. 24 As a result, the models used by central banks perform quite well when nothing very much is happening and fail dramatically when something big occurs – precisely the moment when the model might have something to offer beyond mere extrapolation of the past.

In brief, neoclassical theory has a far more static conception of market ontology than do the neoliberals. In neoclassical economics, many theoretical accounts portray the market as somehow susceptible to “incompleteness” or “failure,” generally due to unexplained natural attributes of the commodities traded: these are retailed under the rubric of “externalities,” “incomplete markets,” or other “failures.” Neoliberals conventionally reject all such recourse to defects or glitches, in favor of a narrative where evolution and/or “spontaneous order” brings the market to ever more complex states of self-realization, which may escape the ken of mere humans.79 This explains why the NTC has rejected out of hand all neoclassical “market failure” explanations of the crisis

Neuroscience and evolutionary biology confirm that rational expectations and the Efficient Markets Hypothesis capture only a portion of the full range of human behavior. That portion isn’t small or unimportant—it provides an excellent first approximation of many financial markets and circumstances, and should never be ignored—but it’s still incomplete. Market behavior, like all human behavior, is the outcome of eons of evolutionary forces. In fact, investors would be wise to adopt the Efficient Markets Hypothesis as the starting point of any business decision. Before launching a venture, asking why your particular idea should succeed, and why someone else hasn’t already done it, is a valuable discipline that can save you a lot of time and money.

Which in one way brought it closer to the Keynesian idea of multiple equilibria, but without any implication that one equilibrium is superior to another. Quoted in Skidelsky (1992), p. 457. Presidential address to the American Economic Association: Lucas (2003), p. 1. New Keynesian models incorporated one or all of: efficiency wages, staggered wage setting, incomplete markets, search and bargaining, imperfect competition, liquidity constraints and co-ordination failures. Wren-Lewis (2012). Thus market interest rates will react to what the central bank is expected to do, rather than what it does, which means it needs to do very little. However, for the rule to work people must believe not only that the rule will be followed, but also that it is correct. 409 No t e s 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 Congdon (2007), p. 14.

The model predicts a very low equity risk premium (well below 1%) due to the low observed volatility of consumption growth and low observed correlation between consumption growth and asset returns, unless an extremely high risk aversion coefficient is used. A huge academic literature has tried to reconcile this puzzle, using market frictions (borrowing constraints, limited market participation, incomplete markets, and idiosyncratic risk), non-standard utility functions (habit formation, recursive utility), modified consumption data (durable goods, luxury goods, long-term consumption risk), and biased sample explanations (survivorship bias among countries studied, absence of negative rare events in the sample, unexpected repricing of equities or bonds) as rational explanations for high observed equity outperformance—but there is little consensus to date.
