    Is a REE fully revealing if the price is a an invertible function of the weighted-average signal?

    In my working paper, I have agents with a basic information structure:

    s = w + e

    s is the signal, w is the fundamental value (that we want to guess) and e a normal error.

    All agents in the same group have the same signal and the same risk aversions.

    Danthine (1978) says that if agent display different risk aversion or different information, there is not sufficient statistic for the fundamental value. Indeed, the price is an invertible function of the weighted-average signal.

    However, can we say that the weighted-average is linear sufficient and therefore, the equilibrium is fully-revealing?

    Dear Mr. Borocco,

                                   I would like to bring to your kind notice my published paper on Implementing Pareto Optimal Asset Prices which has been published in Quantitative Finance as an Archived Paper and which is listed on my RG page which may give you some clues as to your problem of computing REE using sufficient statistics. You may get some help out of it. Thanks for drawing my attention to your problem, good luck. Earl Prof. (Sir Ashutosh Mukherjee University Institute Chair) Dr. (D.Phil.)

  • Daniel Chorzelski added an answer:
    What methods beyond historical data can be used to simulate parameters (e.g. volatility of commodity prices) financial Monte Carlo simulation?

    I am working on Monte Carlo analyses to support financial decision making on a corporate level (no financial market data). A good example is the valuation of a coal power plant. This can be done with many different methods, Monte Carlo being one of them. I assume that many factors that determine the NPV of the plant are volatile (e.g. electricity prices, coal prices and many more). Now I would like to calculate a large number of scenarios of how these volatile input parameters could behave and calculate the NPV for each scenario to better understand my risks. My question is: what methods do you use or are familiar with to determine the distribution of these parameters (and the joint PD of correlated parameters)?

    There are many simple ways to do this that I know are used in practice like using historic volatility (thus assuming no change in the volatility) or trusting some expert with the estimation of the input. Yet I find very little material that approaches this topic from a more analytic perspective. I would be very grateful for any comments and especially suggestions for in-depth reading on the topic. Thanks a lot!

    Daniel Chorzelski

    Thanks very much for your answers, I highly appreciate your input. 

    Towards the answer provided by Mr. Sergio Zuniga-Jara: I was not aware of this literature and will definitely go through it as it relates quite closely with my research interests. I understand the importance of the cost of capital in this context and the role it can take in accounting for risk in any valuation with uncertainty. Yet the advantages I perceive of modelling expected cashflows explicitly still hold once I adjust the cost of capital in the suggested ways. For example I am interested in creating confidence intervals around valuation estimates, this I believe is only possible with explicit cash flow modelling.

    Towards the answer provided by Mr. Peter Monkhouse: I fully agree with you that the questions emerging from the proposed analysis will bring me very quickly into real option applications and this is indeed another of my research interests. Monte Carlo simulation is also one of the ways to compute option values and the questions of how I build bottom-up estimates for expected cash flows in a Monte Carlo real option setting still need to be addressed. As you point out the level of interconnectedness is usually quite high and has a high impact on questions of valuation. In fact there is a literature comparing Value-at-risk value "with correlation" and "without correlation", the stark difference in VaRs point to the importance of explicit measurement of correlations between stochastic variables that affect expected cash flows.

  • Nabila Nisha added an answer:
    What is the effect of the securitization transactions on credit risk in an emerging economy?

    There is no clear evidence regarding the effect of securitization transactions on the risk in the financial system. The literature about this subject is incipient for emerging economies and, in particular, for Latin American countries. A possible justification for this fact can be a lack of a developed financial system in these countries.

      ABSTRACT: Financial markets have suffered the greatest dislocation following the truly seismic significance of the global financial crisis. Regulators argue that the banking sector played a particularly special role in triggering the causes of the subprime debacle, thereby leading to the occurrence of the global financial crisis. Banks previously functioned as only a financial intermediary, but certain developments in the international banking sector like deregulation, technological progress, consolidation and competition, secularization and financial innovation, resulted in banks being involved in subprime lending activities and hence, a reason behind the financial turmoil. The aim of this paper is to scrutinize the special role of banks in the global financial crisis and to stress on the need for increased regulation and their implications on the banking sector. The current study will thus contribute to the examination of the salient features of the global financial crisis and provide regulatory suggestions for the banking sector and the government as a whole.

    Under which conditions a perfect hedge can be achieved in a market characterized by random jumps and stochastic volatility?

    We know in the literature that in a market extended to contain swap contracts whose payoffs depend on the realized higher moments of the state variable process, a perfect hedge can be achieved. Are there any other conditions that lead to a perfect hedge in a market characterized by random jumps and stochastic volatility?

    Dear Prof. Doffou,

                                   If you are willing to go even more into technical and technological details then I would like to draw your attention to my published research on the String Theory of Stock Market systems listed on my RG page and you will see that under discontinuos stochastic volatility of the environment from which the fundamentals of asset pricing and management and engineering potentials are drawn some additional physical structural engineering is required to the stock market system which includes laws on no arbitrage, short and medium range planning and managerial coordination of individual plans so as to engineer a econophysically consistent asset pricing system. But once that has been constructed as i have shown with experiments over various levels of aggregation that the system can achieve rational expectations Arrow-Debreu equilibrium in genetic meanfield systems. The system can be shown to be conserving Matter and Energy fairly efficiently in a dynamic equilibrium sense. It is efficient in all senses. Earl Prof. (University Institute Chair) Dr. (D. Phil.)

    Which is the best model for Event Study Methodology?
    There are different models that are being used to estimate the stock returns under event study methodology such as; arbitrage pricing theory (APT), capital asset pricing model (CAPM), modified market model (MMM) and market model (MM).

    My question is which one is better between the market model and CAPM to estimate the return while studying dividend announcements? How will alpha and Beta be estimated under the market model and CAPM in the equation for event study methodology’ i.e Rit = αi + β (market return) + εit?

    Dear Prof. Panda,

                                    It is a interseting question you have asked, some events I have done research on since my Doctoral Thesis at NYU in 1993, and especially since this model has been adapted a number of times in answering questions on Quantitative Finance & Kinematics. If you wish to you can take a look at my paper on Markov Processes and Expected Utility analysis or Haag's Theorem paper on my Research Gate website. I believe these models are being used worldwide for fundamental research in Quantum Physics as well as Quantum Econophysics and Quantiative Finance. It develops on a model of Radner & Rothschild published in JET in 1975. The idea is that Circuit Breakers in Stock Markets to control extreme fluctuations due to behavioral factors of markets are necessary in principle for Financial Engineering to give sustainable solutions but that by itself does not gurantee that markets will reach equilibrium on a sustained basis as you need energy and participation by investors to run financial exchanges. Energy requirements make Stock Markets go topsy turvy sometimes and so does negative investor participation and it is difficult to say whether  circuit breakers in stock markets can aggravate these factors which are both physical as well as economical being based on incentives. So without answering your specific question I would say that you cannot really treat circuit breaker events in the same manner as we treat structural breaks in any econometrics modelling involving policy.

    Any advice for a "standard" data set for commodity spread options valuation ?

    I am looking for a data set to test a local volatility algorithm pricer for spread or crack options on commodity (WTI). I would need 

    - Future data quote markets

    - Options data (call / put) quote markets considered on spread option maturity

    - Ideally : spread or crack quote markets,

    - Ideally : corresponding Kirk / Bjerksund or Monte Carlo reference prices.

    To your knowledge, is there any standard already considered data set to test performance and precision of the method ?

    Thanks for any contribution !

    Thanks for your answers.

    I could indeed build my own theoretical data set, having a look to real data, for instance CBOE : in particular, CME exhibits WTI call / put / futures, as well as spread options quotes to test against.

    However, I am surprised not to have found such a data set in the academic litterature, as well as basic results to start a first analysis. This work surely already exists.

    What is reliable unit root test to be tested first before apply structural break test?

    I will employ the structural break test in my study to find the exact date of global financial crisis. But before apply the structural break, I will run for unit root first. My question, what is the reliable unit root test to testing for stationary if I apply the structural break test. In my research proposal, I use ADF test, PP test and KPSS test. Is it reliable? or should I employ the zivot-andrew test to exchange withthe KPSS test. Thank you for your helps.

    Soumitra K Mallick

    I have a question which is are you planning on using the results of your unit-root test to test for the structural break test or somehow making adjustments to the model before you do the latter test? If not then you should use the structural break test in the data which is model independant as long as you are using parametric estimation procedures and then test for the unit root using your model. If both are cleared then you should expect a high R-squares I guess, I don't know. SKM QC PhD EPS Fellow (Indirect)MES MRES MAICTE

    When should we use SUR instead of fixed or random effect model?

    We are doing research on capital structure. To the best of my knowledge, researchers usually applied panel with fixed of random effect. Few studies use SUR when they focused on macro variables. When should we use SUR in stead of panel with fixed or random effect? As the results I got quite different when running SUR. Many thanks 

    Soumitra K Mallick

    All of them are used in Simultaneous Equation Models. So that is the similarity. SURE is used when you are not "sure" about what are the structural equations so you include some SUR regressions trying to capture additional information. That's the best advice I can give. SKM QC FEPS

    What is the difference between two tracking error calculations for passive mutual funds widely used in academia?

    I am interested in why different measures are used to calculate TE; specifically, why TE is often calculated as the standard deviation of portfolio and benchmark returns or as the standard deviation of residuals from a regression of portfolio returns on benchmark returns, that can be decomposed into factor returns of the benchmark.

    Though both measures are widely used and at least for the first calculus a clear drawback is that if constant return differences are found TE is incorrectly 0, I don't see how the second calculation would address this problem or what problem is addressed using this alternative calculus?

    Any suggestion is highly appreciated! Many thanks in advance!

    Jan Leicht

    First of all thanks for your hints, much appreciated. Though I keep struggling that TE is of any use in performance evaluation for active portfolios, I definetely see your points. Today, I found a hint that this measure helps differentiating risks caused by physical and synthetical replication; also the residuals would capture any deviation from a full-cash position in a perfectly replicating portfolio, which also is meaningful as the other TE measure technically assumes a beta of 1 (in case of CAPM).

                          I have a suggestion which is to use an Econophysics model using the Quantum Mechanics approach. Try an equal weighting of all the stocks in CL1- CL9 say and compare the value of the mean of the returns by taking averages say. Then repeat this experiment with a different probability weightage and calculate the grand mean. Keep doing this till you find the best grand average return or at least locally best. The portfolio wights being orthogonal to the set of returns will give you the most efficient portfolio on oil stock futures. I am sure this will have additional efficiency properties.

    What do you think of the "health" of the Capital Asset Pricing Model?

    The CAPM is based on a robust theoretical framework, but empirically demonstrated weakness. The beta does not seem to be the only factor that can explain the risk-return relationship. Do you really think that the CAPM is dead?

    Dávid Zibriczky

    We have studied CAPM whether it's linearity holds in extreme conditions or not. We found that in come cases the nullhypothesis of CAPM linearity should be rejected. You can find more details here: https://www.researchgate.net/publication/227358232_Non-parametric_and_semi-parametric_asset_pricing

    We also studied the capability of capturing risk in one meausre and predicting future returns for securities. We compared one factor models, like standard deviation, CAPM beta, and additional two entropy based methods. Based on the results we found both advantages and disadvantages. CAPM beta is good for explaining returns in short term, but it less effective predict them for the next period because the value of CAPM beta for each securities is changing with a high variance over the time. More details here: https://www.researchgate.net/publication/270221149_Entropy-based_financial_asset_pricing

    Overally I think the theory is usable, however it has weaknesses. It can be a good basis for a more efficient multi-factored models, like Fama-French model (SMB-HML), Carhart model (SMB-HML-Moment) or additional factors like liquidity or entropy.

      ABSTRACT: We find that the CAPM fails to explain the small firm effect even if its non-parametric form is used which allows time-varying risk and non-linearity in the pricing function. Furthermore, the linearity of the CAPM can be rejected, thus the widely used risk and performance measures, the beta and the alpha, are biased and inconsistent. We deduce semi-parametric measures which are non-constant under extreme market conditions in a single factor setting; on the other hand, they are not significantly different from the linear estimates of the Fama-French three-factor model. If we extend the single factor model with the Fama-French factors, the simple linear model is able to explain the US stock returns correctly.

      ABSTRACT: We investigate entropy as a financial risk measure. Entropy explains the equity premium of securities and portfolios in a simpler way and, at the same time, with higher explanatory power than the beta parameter of the capital asset pricing model. For asset pricing we define the continuous entropy as an alternative measure of risk. Our results show that entropy decreases in the function of the number of securities involved in a portfolio in a similar way to the standard deviation, and that efficient portfolios are situated on a hyperbola in the expected return - entropy system. For empirical investigation we use daily returns of 150 randomly selected securities for a period of 27 years. Our regression results show that entropy has a higher explanatory power for the expected return than the capital asset pricing model beta. Furthermore we show the time varying behavior of the beta along with entropy.

    The data I have is stationary at level for both of the two variables. Can I apply VAR?

    Ghazi Al-Assaf

    Yes in this case you can use VAR. However, I suggest to check the stantionarity of your series using other unit root tests such as PP and KPSS. If you have the same results, you need to to estimate VAR then, you can also try the SVAR.

    Is the Fed interest rate as a measure of the liquidity crisis is not appropriate?

    I am using the fed rate as a proxy for Liquidity crises in US, however I had a comment that  the interest rates can be used for general monetary policy purposes. So, I have to provide evidence that the Fed interest rates are not used in us from 1954 to 2011  for general monetary policy purposes, then this quantity cannot be used as a measure of liquidity crisis. Is there any thing in the literature related to this issue. what is the best proxy for liquidity crisis ( credit crunch) ?

    Dear Mohammed, I am attaching my RIPE paper.

      ABSTRACT: This paper suggests that the dollar is not threatened as the hegemonic international currency, and that most analysts are incapable of understanding the resilience of the dollar, not only because they ignore the theories of monetary hegemonic stability or what, more recently, has been termed the geography of money; but also as a result of an incomplete understanding of what a monetary hegemon does. The hegemon is not required to maintain credible macroeconomic policies (i.e., fiscally contractionary policies to maintain the value of the currency), but rather to provide an asset free of the risk of default. It is argued that the current crisis in Europe illustrates why the euro is not a real contender for hegemony in the near future.
