Warren Buffett in this Fortune essay explains why he believes women are key to America’s ongoing prosperity.

Most people go though life not really getting any smarter. Why? They simply won’t do the work required.

Tom Russo is a partner at Gardner Russo & Gardner and has managed to beat the S&P 500 index by 4.7 percentage points annually between 1984 and 2011.

Warren Buffett is a businessman and philanthropist. As Chairman and Chief Executive Officer of Berkshire Hathaway Inc., Mr. Buffett has invested in a broad range of companies from See's Candies to Fruit of the Loom.

Money manager Jeff Matthews in this blog post offers a thoughtful summary of what he considers the highlights of last weekend’s Berkshire Hathaway annual meeting.”

Warren Buffett told CNBC, “We’re selling Moody’s at six times what we paid.”

This week the legendary Guru Warren Buffett, despite an aversion to technology, lost his Twitter-innocence at age 82 and tweeted his first digital proclamation of being to a welcoming cyber-existence with: “Warren is in the House.” The Wall Street Journal responded with a Twitter welcome that read, “Pigs aren’t flying, lambs aren’t lying down with lions, and hell isn’t getting any cooler. But Warren Buffett is joining Twitter.”

Warren Buffett is arguably the most successful investor in history, and a good part of his success is his ability to make investment decisions without being influenced by the combination of emotional factors and subconscious biases that govern most human behavior.

There was no big news at Berkshire Hathaway Inc.’s annual meeting this past weekend, but there was one great lesson for investors: Perhaps the most important thing you can do when everything seems to be going right in your portfolio is to listen to somebody who insists you are wrong.

"In 1948, we made our GEICO investment and from then on, we seemed to be very brilliant people."

Given that it’s the Berkshire annual meeting this weekend, now is as good a time to roll out these quotes from Warren himself.

Alternative methods have some use, but we think discounted cash flow is the most fundamentally sound way to value the conglomerate, as we discuss in the final installment of our 5-part series.

In Part 4 of a 5-part series, Morningstar's Gregg Warren and Drew Woodbury say valuing Berkshire's insurance and investment units using the float method is hypothetically an improvement, but in practice a number of important problems pop up

In Part 3 of a 5-part series, Morningstar's Gregg Warren and Drew Woodbury say the so-called two-column approach to valuing Berkshire can be useful, but it also has significant shortcomings.

In part 2 of a 5-part series, Morningstar's Gregg Warren and Drew Woodbury look at how book value can provide a rough guide to Berkshire's intrinsic value.

In Part 1 of a 5-part series, Morningstar's Gregg Warren and Drew Woodbury explore the pros and cons of using an earnings multiple to value Berkshire Hathaway.

A look at the worldview and investment philosophy of one of the great investors of our time. Plus, five ETFs that we believe have many of the characteristics that Munger (and Buffett) look for

Although the public is still uncertain who will succeed the Oracle, the split-up of the chairman, CEO, and investment roles likely won't alter Berkshire's overall strategy.

Buffett has the discipline to guide capital back into his firm rather than use it for dividend payouts, but most companies are better off distributing excess cash to shareholders, says Morningstar's Josh Peters.

Buffett has limited opportunities to continue allocating capital within Berkshire at large returns, making it more difficult for the firm to not pay a dividend, says Morningstar's Gregg Warren.

Berkshire still has deep competitive advantages, but its size will cause its moat to narrow over time, says Morningstar's Gregg Warren.

We'd like to see Buffett address future acquisitions, his take on the economy, the firm's succession plan, and more at this year's annual meeting.

Morningstar's Drew Woodbury says Berkshire's increasing cash position and Buffett's succession plan will be among the main focus points this weekend in Omaha.

Ahead of its annual meeting this weekend, wide-moat rated Berkshire Hathaway (BRK.A) (BRK.B) released results for the first quarter of 2013 that were much stronger than those from the year-ago period. First-quarter revenue increased 15% year over year to $43.9 billion on improved operating results from each of its operating segments. With expenses rising at a much slower rate than revenue, and most of the gains from investments and derivatives falling straight down to the bottom line, Berkshire reported a 49% increase in pretax earnings (to $5.0 billion) and a 51% increase in net earnings (to $4.8 billion). Stripping out the impact of investments and derivatives, operating earnings increased 42% to $3.8 billion. Net earnings per Class A equivalent share were $2,977.

Iron Man 3 has passed the $1bn mark at the global box office, less than four weeks after it first hit cinemas.

What's the most difficult job in marketing? Change. And J.C. Penney is the latest example of how hard that is. In the year since now-departed Ron Johnson introduced his new strategy for the brand, sales were down 25%, the stock was down 66% and the company has lost $985 million.

Former Fed Chairman Paul Volcker warned of the risks of an asset bubble forming given the incredible amount of liquidity the Bernanke Fed has injected into the market, even though he said banks are substantially stronger than before the crisis on Wednesday. Volcker also indicated that in the U.S. government makes up about 35% of GDP and that the financing of the residential mortgage market by the state has led to a dysfunctional financial system.

The brouhaha over Carmen Reinhart’s and Kenneth Rogoff’s article “Growth in a Time of Debt” may be the most conspicuous and incendiary scholarly controversy since 1974, when two earlier economists, Robert Fogel and Stanley Engerman, published a notorious book, Time on the Cross, defending the efficiency of American plantation slavery.

If we want to understand what drove the Boston Marathon bombing suspects, Tamerlan and Dzhokhar Tsarnaev, to terrorism, the answer almost certainly does not lie in Dagestan, where the brothers lived before moving to the United States, or in the two wars fought in Chechnya in the last 20 years. Instead, a key to the Tsarnaevs’ behavior may perhaps be found in developments in England 500 years ago.

“Writing isn’t hard work, it’s a nightmare,” Roth said in 1987.

“Building a new and livable world will necessitate thousands of little changes.”

“Imagine immensities, don’t compromise, and don’t waste time.”

The pre-societal, animal model of conflict resolution is simple, brutal, and effective. Leaving aside political gambles, moral considerations, and the like, the strong are more willing to fight for their self-interest, while the weak find it more advantageous not to assert themselves. Extrapolated to a fairly simple conflict of interest — wealth redistribution — do modern humans operate under the same logic?

Central Park almost didn’t exist. When it was first proposed, no comparable urban green space could be found in the whole of the United States—and it seemed unlikely that one would arise on land that could be put to other, more profitable use – especially with New York real estate values on a steady rise. But on May 5, 1851, Mayor Ambrose Kingsland proposed that a large public park might be just the thing for the growing city. Not only could it have a salutary impact, but it would allow Europeans to see that Americans could, too, be cultured and refined. Their Hyde Parks and Tuileries Gardens had nothing on us.

There seems to be only one kind of loan that bankers want to make—SBA loans. SBA stands for Small Business Administration, a federal agency that guarantees certain loans made by banks that operate within its guidelines.

Warren Buffett and Ray Dalio are two of the most well-known, successful investors in the world. And The Wall Street Journal’s Jason Zweig says they have at least one key trait in common: They are open to criticism and self-doubt.

While not written specifically for investment managers, the subject matter of this McKinsey Quarterly article – building an effective organizational risk “culture” – is nonetheless quite relevant to them.

President Obama said the conduct involving the Internal Revenue Service's targeting of conservative groups for extra tax scrutiny was "inexcusable" and that acting IRS Commissioner Steven Miller is out

Raico grew up in the Bronx, but in contrast with the leftist views common in his family’s apartment building and neighborhood, he acquired from an early age a sympathetic grasp of the isolationist wing of the Republican Party. In high school, he joined Youth for Taft, where he encountered George Reisman. While still in high school, Raico and Reisman became interested in Mises, and Raico describes their hilarious attempt to meet Mises, in the guise of door-to-door salesmen for The Freeman.

Today, roughly one-quarter of the world’s population lives in conflict-affected and fragile states. Despite vast sums of money spent aiding such states over the last 50 years, armed conflict and violence continue to blight the lives of millions of people around the world. International and national partners must radically change the way they engage such states.

The Bank of England has upgraded its economic growth forecast. BBC reports. The perennially gloomy Sir Mervyn King says the Bank now expects GDP growth of 0.5% during the current quarter. This flies in the face of the current vogue for seeing the UK economy as a basket case, limping from one lacklustre economic quarter to the next as Cherry Reynard reports

“Maybe you have to believe in the value of everything to believe in the value of anything.”

“I don’t think we can separate art from overall human dignity and hope.”

In any conversation, organizational or otherwise, people tend to overuse one particular rhetorical tool at the expense of all the others. People’s default mode of communication tends to be advocacy— argumentation in favor or their own conclusions and theories, statements about the truth of their own point of view. To create the kind of strategy dialogue we wanted at P&G, people had to shift from that approach to a very different one.

Since before the tech bust, we’ve been suggesting that while Americans “think” they’re getting richer... they’re actually heading in the other direction. They’re getting poorer.

On Tuesday a group of scientists published a protocol, a set of instructions for running an experiment, which represents the culmination of a year’s discussion on the problems inherent in academic publishing. The protocol is the first in the Registered Replication Reports project. The scheme, led by Alex Holcombe, Bobbie Spellman and Daniel Simons, is far reaching, and requires putting aside egos and working together across universities and research groups to raise the standard of research.

What is science revealing about the nature of the criminal mind? Adrian Raine, a professor at the University of Pennsylvania, is an expert in the expanding field of “neurocriminology.” He has written The Anatomy of Violence, a sweeping account of crime’s biological roots, including genetics, neuro-anatomy and environmental toxins like lead. He spoke with Mind Matters editor Gareth Cook.

Almost fifteen years ago, in a book called “Chance, Development, and Aging,” the gerontologists Caleb Finch and Thomas Kirkwood described a truly elegant study of biology: a batch of roundworms, all genetically identical, raised on identical diets of agar. Despite having identical genetics and near-identical environments, some worms lived far longer than others. The lesson? The classical equation of “life = nature + nurture” had left out chance.

I now know why I gained more than 30 pounds in my early 20s: I was lonely. I had left my beloved alma mater upstate for graduate school and a job in the Upper Midwest. I knew no one and felt like a fish out of water.

When we asked Bill Gates to curate a list of his favorite talks, his first response was, “There are too many to pick, really.” Here, he's whittled it down to 13 essentials.

It’s not a well-kept secret, either. Just a simple string of characters—maybe six of them if you’re careless, 16 if you’re cautious—that can reveal everything about you.

Microsoft aims to upgrade the software more frequently, about once a year, rather than every two or three years as it’s done in the past, said the people, who asked not to be identified because the product plans are private. The company plans to unveil the first of these updates in 2013, one of the people said.

A cascade of misfolded proteins may trigger Alzheimer's By Carrie Arnold Researchers have untangled some of the neurological events that may ultimately lead to Alzheimer's disease. Two new studies show that a protein implicated in this form of dementia can infect other neurons to spread disease across the brain. These problematic proteins clump together, which can lead to cognitive problems.

A species of giant tortoises from the Galapagos Islands could be brought back from extinction despite the death earlier this year of the famed "Lonesome George," a tourist magnet and conservation icon who was the last of his kind.

For every one unit of energy that is converted into electricity in power plants today, two units of energy are thrown away. This wasted energy is primarily in the form of heat – or thermal energy – and, there is technology available today that can turn this waste into a usable energy stream.

This is the first study to examine what factors are associated with an increased follower-count on Twitter over an extended period of time. Hutto et al. (2013) studied 507 Twitter users over 15 months and half-a-million tweets

Under Ravi Venkatesan's leadership from 2004 to 2011, Microsoft India's revenues grew fivefold and the country became one of the fastest growing geographies for the software firm.

Ties between the two men go way back. In May 1939, Churchill reviewed Drucker's first major book, The End of Economic Man, for The Times Literary Supplement, praising him as "one of those writers to whom almost anything can be forgiven because he not only has a mind of his own, but has a gift of starting other minds along a stimulating line of thought."

Most people know Peter Drucker through his books and articles. But Drucker was also a great speaker, especially in the classroom, where his students would sit rapt, listening as he pulled facts from his encyclopedic mind and shared insights on countless subjects. This side of the "father of modern management" is captured in The Drucker Lectures, (McGraw-Hill, 2010). Edited by Rick Wartzman, executive director of the Drucker Institute and a columnist for Bloomberg Businessweek, The Drucker Lectures features 33 of his most important talks. The earliest was delivered in 1943. The latest were given at Claremont Graduate University in 2003, two years before Drucker died. The excerpt below, on "The Future of the Corporation," comes from one of those final lectures.

It's a good time to be a corporate gadfly.

So many of the problems we face today result from poor decision-making by private corporations. Prominent examples include the Gulf oil spill and the seriously weakened financial sector, which is imperiling the rest of our economy. However, so many who describe themselves as liberals or progressives seek to address such problems with more government regulation and programs instead of by preventing the bad decisions at the source, which is likely to be more efficient from a resource utilization perspective.

This letter to Occidental Petroleum’s board of directors from Ralph Whitworth of Relational Investors (VII, September 30, 2009) and Anne Sheehan of the California State Teachers’ Retirement System outlines why the activist investors are seeking to replace at least four board members: “[T]he board, as currently composed, suffers from entrenchment and ossification, which renders each of its members incapable of functioning as vigorous and independent shareholder representatives.”

Recently an acquaintance at the next table in a Palo Alto, California, restaurant introduced me to his companions: three young venture capitalists from China. They explained, with visible excitement, that they were touring promising companies in Silicon Valley. I’ve lived in the Valley a long time, and usually when I see how the region has become such a draw for global investments, I feel a little proud.

Power in modern society is progressively being diffused, moving away from central government to interest groups, even to single individuals. Society and the body politic in democratic societies are becoming pluralist in new ways. This phenomenon was analysed by management guru and social science professor Peter Drucker in his book The New Age. A clear understanding of this development would help political and social leaders to cope with changing electoral aspirations.

The Peter F. Drucker and Masatoshi Ito Graduate School of Management was recognized as an “Excellent Business School” by EDUNIVERSAL, an organization that helps students choose the best business schools worldwide. The Drucker school was honored to be among the 1,000 selected business schools in the world because of its strength in the US and international influence.

Peter Senge (born 1947) studied aerospace engineering at Stanford University before moving into the field of organisational behaviour and becoming director of the Centre for Organisational Learning at MIT’s Sloan School of Management. He is credited with developing the idea of the learning organisation, based on his study of social systems and the relationship of the whole to its constituent parts. A learning organisation, he once said, “is continually expanding its capacity to create its future”.

We live in a world of euphemism. Undertakers have become "morticians," press agents are now "public relations counsellors" and janitors have all been transformed into "superintendents." In every walk of life, plain facts have been wrapped in cloudy camouflage.

The influence the CEO has on people--individually and collectively.

I've read about shamrock organisations, horizontal organisations and federal organisations. I've read about intelligent enterprises and spider-web organisations. The most-quoted management guru Peter Drucker said that managing an information-based organisation is more like conducting a symphony orchestra than running a business on traditional lines. Others have compared it to running a jazz combo, and then there are those who say it's like running a sports team.

The bestselling author answers our readers' questions about business, leadership - and mountain climbing.

Think of them as the "walking dead," a type of customer who currently maintains service with a particular company, but whose next action will most likely be to discontinue that relationship, according to a new study that examines how the customers of a telecommunications firm acquire and discard services over time. The paper -- "Modeling the Evolution of Customers' Service Portfolios," by Wharton marketing professors Peter Fader and Eric Bradlow and a former Wharton PhD student -- focuses in part on whether it is possible to predict future purchasing patterns by looking at past buying behavior.

How CEO George Buckley is managing the yin and yang of discipline and imagination

Some shoppers just can't help themselves and buy mostly on impulse without regard to price. Others are die-hard bargain hunters, who only open their wallets for a discount. Then there are the strategic consumers, who are willing to buy full-price sometimes, but at other times they will wait for a bargain. According to new research by Gérard P. Cachon, professor of operations and information management at Wharton, and doctoral student Robert Swinney, it's these customers that retailers need to focus on in order to reap the full benefits of lean retail inventory management and variable pricing.

Few have had as great an impact on the business world as Peter Drucker. So, it is more than fitting to have his work amplified on Branding Strategy Insider during this years Marketers For Charity effort.

Robert Bruner still remembers the first book he read as a manager. It was 1988, and Bruner, now the dean of the Darden School of Business at the University of Virginia, was an up-and-coming professor, respected for his work in finance. But he'd never managed people before. And when he was charged with overseeing the first year of the school's M.B.A. program, Bruner began to struggle.Under fire, Bruner scrambled for guidance. He found it in Peter Drucker'sThe Effective Executive. In the book, published two decades earlier, the dean of management thinkers—known for his study of GM under Alfred Sloan—offered advice to managers burdened with exactly Bruner's problems.

If you own stock in a company that is ripe for takeover, you should hope the company is not acquired by a private equity firm.

Most people assume that good corporate governance benefits shareholders, and that corruption in a banking system should be rooted out. But just how much benefit does a company really get when it improves its accounting and puts a few outsiders on its board of directors? And when does an anti-corruption crusade start to backfire, causing a chilling effect that denies loans to credit-worthy borrowers? India offers a chance to study both questions, which were the subject of papers presented at a global conference on India's Financial System held in April at Wharton. The conference was organized by Wharton's Financial Institutions Center with the Centre for Analytical Finance at the Indian School of Business in Hyderabad and the Stockholm-based Swedish Institute for Financial Research.

While a number of Indian IT companies are expanding globally, several major U.S. IT firms are increasing their presence in India. Among them is Adobe Systems, which views India as an important development center and a growing market for its products. In the second of a two-part interview with Knowledge@Wharton, Adobe president and chief operating officer Shantanu Narayen discusses the company's strategy regarding India and global expansion. In the first part of the interview, published in Knowledge@Wharton, he talks about Adobe's product strategy for the emerging trend of rich Internet applications.

A key element of what has been called "web 2.0" -- along with ideas such as user-generated content and social networks -- is the concept of "rich Internet applications," which use the web as a platform for innovative types of online experiences. A new generation of Internet-connected applications is beginning to emerge led by such companies as Adobe Systems. Knowledge@Wharton recently interviewed Adobe president and COO Shantanu Narayen about the company's latest product introductions. In the second part of this interview, published in India Knowledge@Wharton, Narayen talks about the key role that India will play in the company's global growth strategy.
