Great Intro to Media Structures.......2001-02-22

This was the main textbook for my Mass Media class at Trinity University. It was a very interesting book which had a lot of good things to say. I had never conceptualized television and radio as a for profit industry with structures governing their behavior just like the steel or automobile industry. The book does not waste tim eon boring chapters full of gory details about this and that medium of communication. It looks at all media as an integrated system. It was a little dry at times, but not to much for me as an undergraduate. All in all I doubt I could have asked for a better book to introduce me to mass media.

Book Description

The prolonged boom in the US and European stock markets has led to increased interest in the mathematics of security markets, most notably in the theory of stochastic integration. This text gives a rigorous development of the theory of stochastic integration as it applies to the valuation of derivative securities. It includes all the tools necessary for readers to understand how the stochastic integral is constructed with respect to a general continuous martingale. The author develops the stochastic calculus from first principles, but at a relaxed pace that includes proofs that are detailed, but streamlined to applications to finance. The treatment requires minimal prerequisites-a basic knowledge of measure theoretic probability and Hilbert space theory-and devotes an entire chapter to application in finances, including the Black Scholes market, pricing contingent claims, the general market model, pricing of random payoffs, and interest rate derivatives. Continuous Stochastic Calculus with Application to Finance is your first opportunity to explore stochastic integration at a reasonable and practical mathematical level. It offers a treatment well balanced between aesthetic appeal, degree of generality, depth, and ease of reading.

Material every quantitative financial analyst should know........2006-01-25

Time spent to read the book in detail: Four weeks
The book, 295 pages, is ordered as follows:

Chapter 1 (First 50 pages):
These cover discreet time martingale theory.

Expectation/Conditional expectation: The coverage here is unusual and I found it irritating. The author defines conditional expectation of variables in e(P) - the space of extended random variables for which the expectation is defined - i.e. either E(X+) or E(X-) is defined - rather than the more traditional space L^1(R) - the space of integrable random variables. The source of irritation is that the former is not a vector space. Thus given a variable X in e(P) and another variable Y, in general X+Y will not be defined, for example if EX+ = infinity, EY= - infinity. As a result, one is constantly having to worry about whether one can add variables or not, a real pain. Perhaps an example might help:

Suppose I have two variables X1 AND X2. If I am in the space L^1 then I know both are finite almost everywhere (a.e) and so I can create a third variable Y through addition by setting say Y = X1+X2. In the treatment here however, I have to be careful since it is not a priori clear that X1+X2 is defined a.e. What I need is - one of the proofs in the book - that E(X1)+E(X2) be defined (i.e. it is not the case that one is + infinity the other -infinity). If both E(X1)and E(X2) are finite this reduces to the L^1 case. However, because the Author chooses to work in e(P), we still have, in order to show even this basic result, quite a bit of boring work to do. Specifically: if E(X1) = +infinity then we must have, recall the definition of e(P), that E(X1^+)= +infinity AND E(X1-) < -infinity and also, because E(X1)+E(X2) is defined E(X2)> -infinity and so , since X2 is in e(P), that E(X2^-) < -infinity. Now since,
(X1+X2)^- <= (X1)^- +(X2)^-, we have
E(X1+X2)- less than infinity which shows that a)X1+X2 is defined a.e. and b) it is in e(P).A little more work shows that, E(X1)+E(X2) =E(X1)+E(X2).

When one introduces conditioning the above irritation continues. We have that if X is in e(P) that the conditional expectation E(X|L) exist and is in , not as is standard in the literatureL^1, but rather, in e(P). Consequently we can no longer carry out simple operations, normally done without thinking, such as E(X1|L)+ E(X2|L)= E(X1+X2|L), but rather have to pause to check if as in the example above that E(X1|L)+ E(X2|L) is defined etc, etc.

Submartingale , Supermartingales ,Martingales: The definitions here again are a little unusual. The variables for both Sub and Super martingales are taken to be, yet again, in e(P). This in turn forces the definition:

A submartingale is an adapted process X = (Xn,Fn) such that:

1) E(Xn^+) <¥ ( The Standard in the literature is to have E(Xn) <¥
2) E( Xn+1|Fn)>=Xn
Likewise for a supermartingale we get:

A supermartingale is an adapted process X = (Xn,Fn) such that:
1) E(Xn^-) <¥ ( The Standard in the literature is to have E(Xn) <¥
2) E( Xn+1|Fn) <=Xn

These definitions, along with the fact that a martingale is both a supermartingale and submartingale, lead then to the standard - as appears in the literature - definition of a martingale.

Stopping Times, Upcrossing Lemmas, Modes of Convergence: The treatment here is quite nice - modulo the e(P)- inconvenience. The proofs are all given in detail. And the level is at that of Chung's "A Course in Probability Theory", Chapter 9.

Optional Sampling Theorem, Maximal Inequalities: A very rigorous treatment of the Optional Sampling Theorem (OST) is given. The need for closure is emphasized in order for OST to be applied in its full generality. In the absence of closure - the author emphasizes why - it is shown how the OST still applies if the optional times are taken to be bounded. The author then uses these results to show how stopped smartingales - super, sub and marts - are smartingales. Finally, Doobs, submartingle and L^p inequalities are derived.

Chapter 1 (Next 50 pages)

These cover continuous time martingale theory under the assumption that the probability space is complete and the filtration augmented and right continuous.

The treatment here - most of the hard work has already been done in the discreet case - uses the standard bootstrapping technique based on sequences of optional times taking only countable values, along with the assumption of right continuity of paths to generalize the discreet time results - through passing to limits - to analogous ones for a continuous time, i.e. where the index set is a subset of [0, ¥], setting. The Upcrossing lemmas, Convergence results, OST and Doobs inequalities are all derived

Next follows a superb treatment of local martingales.

At this point, and for what follows, the treatment switches to smartingales, with continuous paths.

It is now shown that for any bounded - continuous - martingale M, there exists a unique continuous bounded variation (increasing) process starting at 0 -denoted by [M], such that the process M^2-[M] is a closed martingale. Moreover, it is shown that this process is the limit in L^2 of the Quadratic variation of M. This result is then generalized to the case where M is a local martingale where it is shown that M^2-[M] is also a local martingale and where [M] is now only the limit in probability of the quadratic variation. Next the covariation process for two local martingales [M N] is defined and it is shown that MN -[MN] is again a local martingale.
Finally, integration with respect to integrators of bounded variation is defined for a suitable class of integrands and the "Kunita Watanabe", inequality derived.

All of the above is then extended to the case of Semi Martingales.

Chapter 2 (29 Pages) Brownian Motion
Definition of. Existence is shown. The Weak Markov properties derived. I found the notation in this chapter to be rather cumbersome. One would be better served by skipping this chapter, replacing it instead, by chapter 2 in Karatzas and Shreve's "Brownian Motion and Stochastic Calculus" (KS).

Chapter 3 (80 Pages) Stochastic Integration
This chapter, my favourite in the book, is a detailed discussion of integration with respect to continuous semi-martingales. The approach is modern. The chapter starts with a detailed definition of stochastic integration with respect to a continuous local martingale M. The level of rigour, is at the level of sections 3.1 and 3.2 of KS. However, the approach is different and in my opinion more elegant. Leveraging on the material in chapter 1 the stochastic integral for a square integrable - with respect to the induced product measure-progressively measurable, r.v X is defined to be the unique square integrable local martingale, starting at 0, I, such that for any other continuous local martingale N we have:

[I, N] = X DOT [M,N].

This is then extended to the case where X is only locally pathwise integrable with respect to [M], which is then extended to the case where M is a continuous semi martingale.
It is then shown how in the case where X is simple predictable the above definition yields that suggested by one's intuition, that the space of simple predictable variables is dense in the space of square integrable - with respect to the induced product measure - predictable processes, and that I in this case is an L^2 - this is the usual approach - limit of , with respect to P, of simple integrals.

Following this, is a derivation of Ito's lemma - this says that semimartingales are preserved under smooth transformation. It is then shown that given a P semimartingale X, a probability measure Q equivalent to P, X is a Q semi martingale and its Compensator under Q given by Uq = Up + [logM,X], where M is the Radoyn Nikodym derivative of Q with respect to P. It is then an easy step to conclude that the local martingale component of X under Q is related to that under P by:
LMq = LMp - [logM,X].
Thus the Girsanov theorem is proved. In the case where M is of the form,
M = exp( L - [L]/2), where L is a continuous local martingale, conditions on L , those of Novikov and other weaker one, necessary to make M a martingale are given and proven.

Finally, the Chapter concludes with a detailed section on the Martingale representation theorem. Most of this section is very similar to that in section 3.4 of KS. However, while the treatment there leaves a lot of work for the reader, many of the key results are buried in the exercises, the results here are all spelled out and detailed proofs furnished.

Chapter 4 (84 Pages) Applications to Finance:
I only read, the first 40 pages - the section dealing with the Black and Scholes Economy and that with The General Market Model. The treatment of the Black and Scholes economy - 17 pages -is standard and concise. The General Market model is at the level of chapters 4 and 5 in Nielson Pricing and Hedging of Derivatives Securities"(N). Because however, the Author has spent the time to develop the machinery in detail, unlike in the case Nielsen's 106 pages of "hand waving", the pace is a lot faster and the treatment more general. Moreover, results like, no free lunch with limited risk implying the existence of local martingale measure, based the work of Schaechermayer, something not alluded to in Nielson, are covered here The final 40 or so- which I have not read-pages are devoted to applications of the general theory to pricing specific derivatives.

Good Treatment of Continuous Time Martingales .......2005-06-10

Chapter 1: This is a summary of what every probabilist should know about Continuous Time Martingales. Essentially it does, although in a rather terse fashion, and with no examples, for Continuous Time Martingales, what David Williams book, "Probability and Martingales", does for the discreet time case. By restricting himself to the continuous case, as opposed to the more general cadlag processes, the author is able to provide a simple proof of the Doob Meyer Decomposition. The coverage in this chapter is more extensive than that of Chapter 1 in Karatzas and Shreeve and perhaps closer to ChapterII in Rogers and Williams.

Chapter 2: Essentially a brief introduction to Brownian Motion. I would advize the reader to skip this Chapter and replace it with chapter 2 of Karatzas and Shreves "Stochastic Calculus and Brownian Motion". The coverage there is more rigorous.

Chapter 3:This chapter covers Stochatic Integration with respect to a Continous Time Local Martingales. The coverage here mirrors that of chapter three in Karatazs and Shreve though the notation is perhaps closer in spirit to Chapter 4 of Rogers and Williams, Diffusions, Markhov Processes and Martingales. The construction of the Stochastic Integral is then followed by the usual suspects: Ito's Lemma which says that the SemiMartingale property is preserved under smooth transformations. The Martingale Representation Theorem this says that in the case where the integral is with respect to Brownian Motion, then the integral viewed as a mapping from the space of measurable adapted processes that are square integrable with respect to the product measure onto the space of continuous square integrable martingales is surjective. And last but not least Girsanovs theorem which allows one, modulu the satisfaction of the Novikov Condition, to alter the "drift term" in semi martingales through changing to an equivalent measure.

Chapter 4: I would advice the reader to replace this with chapters 4 and 5 in Nielsen's "Pricing and Hedging of Derivative Securities" for the general theory and chapter 6 for the Black and Scholes Economy. The coverage there is the best I have seen.

Elegant Math Book on Finance - you need the math to read.......2004-01-22

This is a math book first and foremost. It uses advanced mathematical techniques to discuss aspects of randomness that can be used to understand finance. Please don't mistake it for a course to teach concepts in basic finance.

It is a very elegant and sophisticated book for those who are very well versed in the necessary mathematics in stochastic calculus and in particular Martingale theory to show them how these tools can be applied to problems in finance.

If you have the math background and are interested in this topic you will get a lot from this book. If you don't have the math, don't bother. This book will be opaque.

It is indeed meant for learning.......2004-01-02

I completely disagree with Student.

This book is indeed meant for learning. Just do not take it as your first entry into Stochastic Calculus. Take it as a second reading. It is complete, thorough and well, very well written.

It will teach you. A lot. All theorems are cross-referenced, so you will not have any "it is obvious that" etc. Theorems are proved, over and over again, until they hammer themselves in your head.

It is a fine achievement, if you want something quick and dirty read something else.

Not meant for learning.......2001-02-03

Some books are meant to teach, and to elucidate new material; this book is not one of them. It seems the purpose of this book was rather to record for prosperity all theorems related to Stochastic Calculus. Instead of developing any intuition on the subject, the author seems to think the purpose of writing is to use the most elegant proofs with the most modern of mathematical jargon. In short, the book consists of stated lemmas and theorems with terse, undeveloped proofs. This book will not teach you anything.

Book Description

For two decades now, a social dialogue has been in progress concerning industrial relations on a European level. The publication of the first Report of the European Commission on Industrial Relations marks a significant moment: the general acceptance that European Union policy is no longer merely attempting to harmonize national regimes in this area, but focusing instead on the pursuit of such basic aims as keeping workers healthy and safe, ensuring that their interests are represented, and providing some protection from economic uncertainty.

In this book fifteen notable scholars and policymakers from six European countries explore the territory of industrial relations in Europe as it now stands. The important questions for which they provide in-depth materials include: - How far has `Europeanisation' progressed in this field? - In what ways does the monetary union affect industrial relations? - To what extent is the evolving European policy a `pact' between the national employers and trade union organisations? - What subtle variations persist in the theme of worker security versus labour market flexibility? - What is the `new style' of collective bargaining? - Is the power of the state government in industrial relations beyond EU intervention? - How will the Nice Charter of Fundamental Rights affect industrial relations? - What kinds of labour law and social security legislation may be expected in the near future? - How is the globalisation of the market economy affecting wages and working time? and - How does the prospect of EU enlargement to the East affect industrial relations policy? As a detailed analysis of current reality in the field of European industrial relations, this remarkable book is of great value to a wide range of interested parties, including academics, business people and their counsel, policymakers, government officials, and labour lawyers. These essays were originally presented as papers at a December 2000 conference in Modena, sponsored by the Italian Industrial Relations Research Association in collaboration with the European Commission and the Centre for International and Comparative Studies in Labour Law and Industrial Relations of the University of Modena and Reggio Emilia.

From the author: Because the European Union (EU) has sought from its earliest history to accommodate nonmember countries through various preferential arrangements, the further expansion toward the eastern part of Europe is bound to affect the benefits that partners in these preferential arrangements can count on. The effects of entering transition economies (TEs) can be direct, as a result of the TE obtaining access to the four freedoms of the EU. But they can also be indirect, resulting from the way enlargement alters the calculus of EU benefits and costs for present EU members. This paper examines the various preferential arrangements and the major effects that are likely to be experienced by them as a result of the eastward extension of the EU. Given the EU's foreign-policy objectives and the sizable changes that have occurred in Europe, the paper argues that it might now be the appropriate occasion to reexamine those preferential arrangements. The article pays special attention to the ramification of eastward expansion on TEs that will not now or ever qualify for EU membership, yet remain of strategic concern to the EU.

Book Description

Humic Substances color all waters more or less brown. Their concentrations exceed all carbon of living organisms by at least one order of magnitude. Opposite to former paradigms, they participate in almost any metabolic pathway. They protect against UV-irradation, enable indirect photolysis and, thus, purify hazardous chemicals, they provide inorganic and organic nutrients, may form cryptic genes with DNA and dampen metabolic fluctuations. More recently they can increase adverse effects of hazardous chemicals and they can directly interfere with organisms. The book tries to relate effects to structural features.

Book Description

Meet Alexandra, a small-town Texas girl turned fashion correspondent for the respected British Weekly. She wears all the right designers and knows all the right people, but can her reputation survive a collision with a six-foot-plus model at the Chanel Show? The fall has been splashed across every newspaper and television set in the world, it seems, and Alex has sworn to adopt status incognito. But there's one small problem. How do you get the scoop when you're hidden under the covers in your hotel room? Just when all hope seems lost, Alex heard the word that an avant-garde fashion show is happening that night at a shady Parisian nightclub. She can keep her cover and get her story. When she finds both a love interest and perhaps the hottest new underground designer in town at the show, Alex can only wonder if it's all too good to be true.

Don't Waste Your Time!.......2007-09-23

I visit a website by the same name and had been looking forward to reading this for some time. What a disapointment!I am so sick of books that are by the numbers! I wasn't expecting too much, just an entertaining read, but this had a wafer thin plot, a cliched cutesy heroine, and no wit or originality to commend it.

Some like it NOT... Shallow and void of a good plot........2007-05-24

What can I tell you, the best part for me was the fact that the main character was focused on finding a freaky Peruvian designer who comes up with the most divine dresses ever to be made and also the fact that she talks about our pisco sours and Maccu Piccu bars scattered in Europe but other than the that the book is ultra shallow and full of voids I didn't like it even though I am crazy for fashion, I am a fashionista personified but it didn't do it for me.
Dam's swipes at the fashion world's myopia and absurdity amuse when they don't feel shopworn. The plot hangs together by a thread, and the coquetry is forced but Dam has stitched a gossamer-light read with sumptuous material and gentle ribbing. The author tries to deliver a funny story with the ups and downs of the fashionista's world but it's just not enough for the glorified reader.
Read it if you get it for free or if there's nothing else to read but don't think you will be blown away since this is just way too light to capture your heart.

Not much thought.......2007-05-17

This book doesn't really get the mind going and unless you know fashion, some names you won't know. Although it was a cute read, it isn't something I would read again.

More hip than the Devil Wears Prada.......2007-05-10

I enjoyed this book. I enjoy chick lit novels and this was that combined with a lesson in fashion. I learned alot about Paris, fashion week, and designers. I would say that this was in some ways similar to the Devil Wears Prada in that it is about fashion and it's main character is a young female. But this combines humor, romance, and plenty of 80's culture. I would recommend it.

Good beach read.......2007-03-27

Read this book when you want to lose yourself in a entertaining, mindless read!
