Nobel Laureates In Economics

"The main development I want to discuss has already occurred: Keynesian economics is dead [maybe ‘disappeared’ is a better term]. I don’t know exactly when this happened but it is true today and it wasn’t true two years ago. This is a sociological not an economic observation, so the evidence for it is sociological. For example, you cannot find a good, under 40 economist who identifies himself and his work as ‘Keynesian’. Indeed, people even take offense if referred to in this way. At research seminars, people don’t take Keynesian theorizing seriously any more—the audience starts to whisper and giggle to one another. Leading journals aren’t getting Keynesian papers submitted any more."

"We can trust only ourselves. The president of the United States has to look out for U.S. interests -- that is what he was elected to do. He does not have to look out for Israel's interests, nor do I expect him to. The bottom line is that Obama is president of the United States -- not the world -- so when it comes to Israel's interests I trust the prime minister's discretion."

"He advised the audience to remember the Romans, and the fact that as "disagreeable" as they were, the Roman Empire ruled in peace for 400 years."

"All these cries for peace we hear in Israel, especially from our side, do not bring peace any closer -- they only push it away. If you chase peace it only eludes you. That's not game theory; that's history."

"In many real-world situations, cooperation may be easier to sustain in a long-term relationship than in a single encounter. Analyses of short-run games are, thus, often too restrictive. Robert Aumann was the first to conduct a full-fledged formal analysis of so-called infinitely repeated games. His research identified exactly what outcomes can be upheld over time in long-run relations."

"Repetition acts as an enforcement mechanism: It makes cooperation achievable when it is not achievable in the one-shot game, even when one replaces strategic equilibrium as the criterion for achievability by the more stringent requirement of perfect equilibrium."

"The players in a game are said to be in strategic equilibrium (or simply equilibrium) when their play is mutually optimal: when the actions and plans of each player are rational in the given strategic environment – i.e., when each knows the actions and plans of the others."

"The theory of repeated games is able to account for phenomena such as altruism, cooperation, trust, loyalty, revenge, threats (self-destructive or otherwise) – phenomena that may at first seem irrational – in terms of the “selfish” utility-maximizing paradigm of game theory and neoclassical economics."

"A person’s behavior is rational if it is in his best interests, given his information."

"War has been with us ever since the dawn of civilization. Nothing has been more constant in history than war."

"I would like to suggest that we should perhaps change direction in our efforts to bring about world peace. Up to now all the effort has been put into resolving specific conflicts: India–Pakistan, North–South Ireland, various African wars, Balkan wars, Russia–Chechnya, Israel–Arab, etc., etc. I’d like to suggest that we should shift emphasis and study war in general."

"“Torah study is an intellectual pursuit, and honoring this ultimate value transfers to other pursuits as well, Jewish homes are full of books while other homes may or may not be. Jewish homes have overflowing bookshelves. Throughout the generations we have given great honor to this intellectual pursuit…Torah study makes the nation and its people of the finest and highest quality.”"

"I think game theory creates ideas that are important in solving and approaching conflict in general."

""Interactive Decision Theory" would perhaps be a more descriptive name for the discipline usually called Game Theory."

"The strong equilibrium point f just described is one of "unrelenting ferocity" against offenders. It exhibits a zeal for meting out justice that is entirely oblivious to the sometimes dire consequences to oneself or to the other faitheful——i.e., those who have not deviated."

"It turns out that the Romans were champs in making peace. Their motto was that if you want to make peace, you need to prepare for war. They knew game theory."

"Capitulation, sycophancy, and cowardice will only undermine us... Sometimes, you have to courageously follow your own path and not try to curry favor with anyone."

"The world aligns itself with those who are strong, even if they are the embodiment of evil. That is why [Prime Minister Benjamin] Netanyahu's insistence on addressing Congress in an effort to prevent a deal between the United States and Iran is vital..."

"The answer that socialism provided to the age-old question of the proper balance between the public and the private can now, from our current historical perspective, be seen to have been wrong. But if it was based on wrong, or at least incomplete, economic theories, theories that are quickly passing into history, it was also based on ideals and values many of which are eternal. It represented a quest for a more humane and a more egalitarian society."

"From conversations, I became convinced that people who counterfactual upwards (i.e., compare themselves to those richer) want to actively dispossess the rich. As with all communist movements, it is often the bourgeois or clerical classes who are the early adopters of revolutionary theories. So class envy doesn’t originate from a truck driver in South Alabama, but from a New York or Washington, D.C., Ivy League–educated IYI [Intellectual Yet Idiot] (say Paul Krugman or Joseph Stiglitz) with a sense of entitlement, upset some “less smart” persons are much richer."

"Most economists now recognize climate change as a market failure, but only a few understand it as part of the larger pattern of environmental destruction that scientists have labelled the 'Great Acceleration'. Capitalism as currently practised has imperilled the existence of millions of planetary species, as well as the health and well-being of billions of humans. It also threatens the prosperity that it was intended to create. Challenging 250 years of dominant economic thinking, the climate crisis has shown that the unrestrained pursuit of self-interest does not serve the common good. It has shown, in the words of economist Joseph Stiglitz, that Adam Smith's invisible hand - the idea that free markets lead to efficiency as if consciously guided - is invisible because it is not there'."

"To allow arcane trade law, which has been negotiated with scant public scrutiny, to have this kind of power over an issue so critical to humanity's future is a special kind of madness. As Nobel Prize-winning economist Joseph Stiglitz puts it, "Should a group of foolish lawyers, who put together something before they understood these issues, interfere with saving the planet?" Clearly not."

"I recently told Joe Stiglitz how much I admire him. I really think he’s so exemplary, not just because he’s smart but because of what he did in the Clinton administration and what he did at the World Bank. When he won the Nobel Prize, all he talked about to any reporter who asked him questions was that the real problem is world poverty. When I first met him, Dunlop insisted on the young radicals getting together with the real smart guys who were not the radicals, and Stiglitz was one of them. So we got together for lunch at the Harvard Faculty Club. It was a little strained at first, but we had a nice talk, and I finally said to Stiglitz, “Listen Joe, do you really believe that the interest rate is the intersection of the supply and demand for capital?” I said exactly that, and he said, “Yes, I believe that.” So twenty years later I said to him, “Listen Joe, you really threw me a curve ball when you told me you believed this.” I thought if this is what the smartest people in the profession believe, I’m not going to even talk to them; meanwhile he totally revolutionizes capital theory along the lines that supply and demand don’t determine interest rates! Either his views changed, or he was being “in your face” to me."

"My final criticism is that Stiglitz's book is carelessly written. Stiglitz was—and perhaps still is—an outstanding economic theorist. But he has been producing big, loosely argued books. The laudable aim behind them is to inform a broader audience about economic policies that could make the world a better place, certainly with better lives for the poor, and such advocacy has its place in moving people to action. But he lacks the eloquence, urgency, and passion of the preacher, while he has too often abandoned the rigor of the scientist. In my view, he has not yet found a style suitable to the popular exposition of his economic ideas."

"For much of the world, globalization as it has been managed seems like a pact with the devil. A few people in the country become wealthier; GDP statistics, for what they are worth, look better, but ways of life and basic values are threatened. For some parts of the world the gains are even more tenuous, the costs more palpable. Closer integration into the global economy has brought greater volatility and insecurity, and more inequality. It has even threatened fundamental values. This is not how it has to be. We can make globalization work, not just for the rich and powerful but for all people, including those in the poorest countries. The task will be long and arduous, We have already waited far too long. the time to begin is now."

"In the long run, the most important changes required to make globalization work are reforms to reduce the democratic deficit."

"The IMF has been encouraging, sometimes even forcing (as condition of assistance), countries to have their central banks focus only on inflation. Europe succumbed to these doctrines. Today, throughout Euroland, there is unhappiness as the European Central Bank pursues a monetary policy that, while it may do wonders for bond markets by keeping inflation low and bond prices high, has left Europe's growth and employment in shambles."

"The global financial system is not working well, and it is especially not working well for developing countries. Money is flowing uphill, from the poor to the rich. [...] With nearly two-thirds of reserves being held in dollars, the United States is, in this sense, the major recipient of these benefits. If the interest rate America has to pay is just one percentage point lower than it otherwise would be on these $3 trillion of loans from poor countries, what America received from the developing countries via the global reserve system is more than it gives to the developing countries in aid."

"The problem is easy to state: developing countries borrow too much—or are lent too much—and in ways that force them to bear most or all of the risk of subsequent increases in interest rates, fluctuations in the exchange rate, or decreases in income. Given this, it is not surprising that they often cannot repay what is owed."

"Limited liability should not be sacrosanct. Like property rights—including intellectual property—it is a creation of man, to provide appropriate incentives; when that artifice fails to fulfill its social function, it needs to be modified."

"Perhaps the most successful global monopoly is Microsoft, which has succeeded in gaining global market power not only in PC operating systems but in key applications such as browsers. [...] Microsoft's monopoly power leads not only to higher prices but to less innovation. [...] The failure to develop a global approach to global cartels and monopolies is yet another instance of economic globalization outpacing political globalization."

"I have argued that simply as a matter of fairness in trade, it is intolerable for one country to provide, in effect, emission subsidies to its firms. [...] Europe must use the foundations of the international trade law we have created to force any recalcitrant country, any rogue state—including the United States—to behave responsibly."

"The natural resource curse is not fate; it is choice. The exploitation of natural resources is an important part of globalization today, and in some ways the failures of the resource-rich developing countries are emblematic of globalization's failures."

"The job of the Western trade negotiators is to get a better trade deal for their country's interests—for example, gaining more market access and stronger intellectual property rights—without giving up agriculture subsidies or nontariff trade barriers. Fairness is not in the lexicon of these trade negotiators."

"TRIPs imposed on the entire world the dominant intellectual property regime in the United States and Europe, as it is today. I believe that the way that intellectual property regime has evolved is not good for the United States and the EU; but even more, I believe it is not in the interest of the developing countries."

"Intellectual property does not really belong in a trade agreement."

"One of the reasons that basic research is advanced most by not resorting to intellectual property is that while doing so would have questionable benefits, the costs are apparent. [...] Interestingly, even in software, this system of open collaboration has worked. Today we have the Linux computer operating system, which is also based on the principle of open architecture."

"Innovation is important; it has transformed the lives of everyone in the world. And intellectual property laws can and should play a role in stimulating innovation. However, the contention that stronger intellectual property rights always boost economic performance is not in general correct. It is an example of how special interests—those who benefit from stronger intellectual property rights—use simplistic ideology to advance their causes."

"If there is to be support for trade globalization in the developed world, we must make sure that the benefits and costs are more evenly shared, which will entail more progressive income taxation."

"The era of multilateral trade liberalization seems to be nearing an end (at least for a while), as well-founded disillusionment in the developing countries combines with growing protectionist sentiment in the developed world."

"The United States and Europe have perfected the art of arguing for free trade while simultaneously working for trade agreements that protect themselves against imports from developing countries. [...] Western negotiators almost take it for granted that they can control what gets discussed, and determine the outcomes."

"In part, free trade has not worked because we have not tried it: trade agreements of the past have been neither free nor fair. They have been asymmetric, opening up markets in the developing countries to goods from the advanced industrial countries without full reciprocation."

"When I was at the World Bank, it would often be said in the face of obvious failure that our strategy was correct, it just wasn't implemented well."

"New technologies (reinforced by new trade rules) are enhancing the market power of incumbent, dominant firms, such as Microsoft, which are all from the developed world; for the first time, in a key global industry, there is a near-global monopolist."

"Instead, unchecked by competition [by the USSR] to "win the heart and minds" of those in the Third World, the advanced industrial countries actually created a global trade regime that helped their special corporate and financial interests, and hurt the poorest countries of the world."

"Growing up in Gary Indiana gave me, I think, a distinct advantage over many of my classmates who had grown up in affluent suburbs. They could read articles that argued that in competitive equilibrium, there could not be discrimination, so long as there are some non-discriminatory individuals or firms, since it would pay any such firm to hire the lower wage discriminated-against individuals, and take them seriously. I knew that discrimination existed, even though there were many individuals who were not prejudiced. To me, the theorem simply proved that one or more of the assumptions that went into the theory was wrong."

"Seeing an economy that is, in many ways, quite different from the one grows up in, helps crystallize issues: in one's own environment, one takes too much for granted, without asking why things are the way they are."

"I recognized that information was, in many respects, like a public good, and it was this insight that made it clear to me that it was unlikely that the private market would provide efficient resource allocations whenever information was endogenous."

"An early insight in my work on the economics of information concerned the problem of appropriability — the difficulty that those who pay for information have in getting returns."

"Economists often like startling theorems, results which seem to run counter to conventional wisdom."
