Second Inaugural Address Analysis
In conjunction with Abraham Lincoln’s 200th birthday many books were published on our sixteenth United States President. In January 2009, Random House released one of the best books of the busy year, “A. Lincoln: A Biography.” Written by renowned Lincoln historian, Ronald C. White, Jr., it would become the flagship of the many Lincoln works published during his bicentennial. I purchased this book the day it was released. Unfortunately, with so many other books in my review queue, I did not read “A. Lincoln” until recently. I regret this decision as it is one of the best single volume biographies I have read on Abraham Lincoln – worthy to be mentioned alongside David Herbert Donald’s Pulitzer Prize winning biography, “Lincoln.” Prior to writing “A. Lincoln,” White published “The Eloquent President: A Portrait of Lincoln Through His Words” which is to this date one of my favorite books on the subject.
In speaking with Mr. White, I learned that he wanted to write a book that focused much attention on the young Lincoln. Lincoln, growing up on the western frontier, would not have it easy. With little formal education he would become the epitome of a “self made” man, proving that a person can do anything he sets his mind to. During the first three chapters, White develops Lincoln and leads the reader through his formative years which would inevitably shape him into the man he became: frontiersman, invent...

Mean Variance Analysis
However, many investors---both individuals and institutions such as charitable foundations or universities---seek to finance a stream of consumption over a long lifetime. In addition, mean-variance analysis treats financial wealth in isolation from income. Long-term investors typically receive a stream of income and use it, along with financial wealth, to support their consumption.
At the theoretical level, it is well understood that the solution to a long-term portfolio choice problem can be very different from the solution to a short-term problem. Long-term investors care about intertemporal shocks to investment opportunities and labor income as well as shocks to wealth itself, and they may use financial assets to hedge their intertemporal risks.
This should be important in practice because there is a great deal of empirical evidence that investment opportunities---both interest rates and risk premia on bonds and stocks---vary through time. Yet this insight has had little influence on investment practice because it is hard to solve for optimal portfolios in intertemporal models.
This book seeks to develop the intertemporal approach into an empirical paradigm that can compete with the standard mean-variance analysis. The book shows that long-term inflation-indexed bonds are the riskless asset for long-term investors, it explains the conditions under which stocks are safer assets for long-term than for short-term investors, and it shows h...

What Is Jit Analysis
Three significant trends in the local sector -- deals, check-ins, and place pages -- are on a bender and headed for an exciting convergence. When they meet we will see one of three things: a train wreck of incompatibility, an awkward confluence, or a very powerful alignment. I'm hoping for the latter, a sort of local syzygy, because a well-conceived orchestration of these trends will benefit the consumer and it has real potential to take us entirely out of the Yellow Pages era and into exciting, unexplored territory.
This is a two-part post: here I look in more detail at check-ins, deals, and place products (including, briefly, the adventurously named Facebook Places) with an eye to what might follow. In a following post I will discuss how we may more actively ease their convergence with linked data and some basic adherence to extant standards, specifically how these efforts will affect the local consumer.
Place pages and check-ins
The check-in is hardly the apogee of the local consumer experience but it works, and this is what is most important about any product. However successful it is now, the check-in will remain an interim solution for identifying long-term customer/business affinities and physical point of presence. So what's next?
I've written about check-ins previously: since then, Facebook has thrown its hat into the ring with their own place/check-in product, offering little feature distinction outsid...
