Amazon | Economics Rules: The Rights and Wrongs of the Dismal Science | Rodrik, Dani

In the wake of the financial crisis and the Great Recession, economics seems anything but a science. In this sharp, masterfully argued book, Dani Rodrik, a leading critic from within, takes a close look at economics to examine when it falls short and when it works, to give a surprisingly upbeat account of the discipline.Economics RulestheWhether the question concerns the rise of global inequality, the consequences of free trade, or the value of deficit spending, Rodrik explains how using the right models can deliver valuable new insights about social reality and public policy. Beyond the science, economics requires the craft to apply suitable models to the context.The 2008 collapse of Lehman Brothers challenged many economists' deepest assumptions about free markets. Rodrik reveals that economists' model toolkit is much richer than these free-market models. With pragmatic model selection, economists can develop successful antipoverty programs in Mexico, growth strategies in Africa, and intelligent remedies for domestic inequality.Economics Rules

レビュー

In Economics Rules, enjoyment enhances learning, with lessons for economists and non-economists alike--indeed, ten commandments for each. The book is a page-turner with every page carrying an important and memorable take-away.--Margaret Levi, director, Center for Advanced Study in the Behavioral Sciences, Stanford University

The best economists make the best methodologists, and Dani Rodrik is both. His Economics Rules is the single best source for explaining the strengths and weaknesses of economics to an outside audience.--Tyler Cowen, George Mason University, author of The Great Stagnation

Economics Rules, by one of the world's truly great economists, describes in fascinating and incredibly well-written detail what it means to be an economist. In so doing it explains why, and when, economists often get it right, but also why they also frequently go astray.--George Akerlof, Nobel laureate in economics

一つの科学、多くのモデル One Science Many Models
2017年3月9日に日本でレビュー済み
ダニ・ロドリック（ハーバード・ケネディ校教授）の新著。彼は開発経済学の権威で、すでに邦訳著『グローバル・パラドックス』もあります。経済学は役に立つか？景気予想する民間のシンクタンク研究員や株屋さんは経済学の素人。なのにたくさん経済の本を書いてメディアに登場しています。一方で大学の経済学者は「ハローワークて何？」なんて真顔で聞いてきたり、現実経済にはほとんど無知無関心。本書でも、ノーベル経済学賞（スウェーデン国立銀行賞）受賞者でマクロ経済学者のサージェント氏が、メディアの質問に「知らない」と答えた話、同じくノーベル賞受賞者で産業組織論のティロール氏が、受賞理由をメディアの取材で聞かれて困惑した話など紹介しています。

経済学ってなんかおかしくない？そんな疑問をお持ちの方も多いはず。経済学の「科学としての」特徴として（もちろん、トーマス・クーンのお話も登場します）、本書では
１）論理実証主義（ミルトン・フリードマン）
２）水平的進歩
３）方法論的個人主義（アロー・デブリュー、トーマス・シェリングなど）
などが挙がっています。１）は、非現実的な仮定から導かれた命題だからその命題が無意味だとは断言できない、検討する余地があるというもの。２）は新しいモデルが古いモデルを駆逐するというよりも、新しいモデルが次々に出て経済学の語彙や知識を増やしているという現実。３）は社会学や人類学と違い、経済学は文化的要素を無視するというよりも、個々の経済主体の動機から経済全体の振る舞いを説明するという特徴を持っているということで、心理学や社会学の知見も経済学に生かされているという。

また、最近の行動経済学、実験経済学、フィールドワーク、RCT（ランダム化比較試験）などの話も登場します。現実の経済とは実にさまざまな要素で動くもの。それらをすべて加味して議論しようとしても、実は説明できない。経済学でよく言われている格言「原寸大の地図は役に立たない」というのはそのことで、何をもって「役に立つ」と言えるのかを考えることの重要性を説いています。早く邦訳が出ることを期待します。

Il tema del libro, come è scritto nel sottotitolo, è quello di provare a discriminare cosa ci sia di giusto e di sbagliato nella teoria economica, e quindi in ciò che affermano gli economisti. In particolare il libro si concentra sui modelli che sono una delle caratteristiche, per l’autore, più importanti e caratterizzanti la scienza economica. L’accusa è che alcuni economisti abbiano male interpretato il loro ruolo assumendo il loro modello come “il modello” mentre, giustamente, Dani Rordik evidenzia che esistono vari modelli e che ognuno va utilizzato in base al contesto di riferimento. Il problema non è, come affermano alcuni critici della scienza economica, che i modelli siano troppo semplici, anzi la semplicità è un requisito essenziale se si vuole fare scienza. Non sono un problema neanche le assunzioni irrealistiche in generale, piuttosto se sono irrealistiche le cosiddette assunzioni critiche, quelle correlate direttamente ai risultati, ed in questo l’autore è in contrasto con quanto affermava Friedman che ciò che conta sono solo i risultati. Il compito della scienza economica e dell’economista è quindi, soprattutto, di selezionare il giusto modello in base alle condizioni specifiche in cui deve essere applicato. L’errore commesso da alcuni economisti recentemente è stato di essere troppo confidenti in alcuni modelli a scapito di altri. L'autore conclude che l’economia (se giustamente intesa) ci fornisce gli strumenti analitici per indirizzare i grandi problemi pubblici del nostro tempo. Ciò che non può fornire è una risposta definitiva e universale, i risultati forniti dalla scienza economica devono essere comunque combinati e tener conto dei giudizi di valore, le valutazioni e la evoluzione delle tematiche di natura politica, etica e pratica.
In definitiva un libro veramente molto bello, molto ben scritto e di grande equilibrio, che riscatta, in qualche modo, la scienza economica dal discredito in cui è stata condotta da alcuni economisti. Un libro che dovrebbero leggere tutti gli studenti di economia per acquisire un giudizio più critico, ma anche più sano, sulle materie che studiano.

An excellent introduction to economic modeling and behavioral economics
2015年12月3日にアメリカ合衆国でレビュー済み
Amazonで購入
I just finished reading Harvard economics professor Dani Rodrik's new book, Economics Rules: The Rights and Wrongs of the Dismal Science. My overall impression was that it is lively, well-written, and completely understandable by readers of ordinary capability. The arguments he makes are cogent and well-conceived. Rodrik's book is a welcome corrective to the doctrinaire blather that we continually get from economists who should know better, but who are either too lazy or self-regarding to quit worshiping idols of their own creation. My personal view is that markets are human constructs, with all the flaws and foibles that we create for ourselves. The fact that some of these people resort to arcane mathematical symbols and runes when they can't make sense of themselves in a declarative sentence has become a scandal, especially in light of our experience over the past seven or eight years.

Prof. Rodrik is a specialist in international development and is an expert on developing logical models to explain the nuances and differences in economic behaviors used by state entities, groups, and individuals. His central premise in his book would be that conceptual models are as many as are necessary to identify the salient factors that govern economic behavior and that the modeling itself needs to correspond as closely as possible with the realities of economic behavior. In this respect Rodrik's approach close resembles that of a specialist in the life sciences, such as a botanist, whose work involves identifying, cataloguing, and differentiating among the major and minor characteristics of the species of the lifeforms with which they deal.

Unlike the physiognomy of lifeforms, economic modeling deals with concepts, some of which are hard to describe in plain language; so, not infrequently, economists utilize mathematical concepts and analytic techniques to explore the various behaviors of their theoretical constructs as to the ways they interact in response to internal and external pressures. They also use mathematics to clean up the untidiness of common language and to ensure that cardinal and subsidiary relationships are properly shown and that all necessary constituent components are properly accounted for. Regrettably, the mathematics sometimes takes on a life of its own, and for some, mathematical consistency sometimes takes precedence over observable reality. Other times, mathematical models, elegant as they are, come to conclusions that are absolutely dead wrong. It is not that complete and accurate information is not available; it simply may not fit the mathematical construct that the economist has created to support his conclusion. It is not for nothing, as the joke has it, that economists have successfully predicted nine of the last five recessions.

Frequently, economic theorists employ a variety of competitive strategies sometimes referred to as Game Theory to test their economic prognostications. The idea is not only to explain events that occurred in the past, but also to attempt to predict what might happen in the future based upon ongoing and future events if things go in accordance with patterns of predictive behavior.

I like the idea of using economic modeling, so long as the models themselves clearly reflect the salient forces, economic and otherwise, that control economic outcomes, including externalities and spillover effects. But there are dangers to this approach. They arise principally from a variety of causes, but the one we see most often, and not surprisingly in political rhetoric, is what some have called 'the overvalued idea'. The British philosopher Sir Isaiah Berlin addressed this phenomenon when he divided thinkers into two categories, those who are captivated by a single big idea, a grand vision – Karl Marx's critique of capitalism being a foremost example – in describing how the world works, whom Berlin dubbed 'hedgehogs', and those, whom he called 'foxes' who know many things. Foxes have no use for grand theories but rather who take a more modest approach in describing cause-and-effect relationships, often with the result that superficially similar events can be described in contradictory ways. The hedgehogs, with their unrelenting emphasis on overemphasizing the core tenets of their Big Idea tend to view the world through a single lens, even when the distortions inherent in that approach make their conclusions unreliable. By temperament, they are cautious in attributing grand hypotheses to events or processes that contain ambiguities of one sort or another, or which may contain unknown factors that influence the outcome is being examined. Foxes, of which Prof. Rodrik can justly claim to be one, examines the influences that many causative factors may have in describing and analyzing events. It's much harder work, but the results speak for themselves. Best of all, the more modest, modular approach that Prof. Rodrik advocates is less likely to suffer the public embarrassment that so many highflying, single-idea economists experience when their grand ideas crash and burn.

Prof. Rodrik is a member of a growing school of economists who is doing pioneering work in the area of behavioral economics, which combines economic theory with research-validated behavioral models that were developed by psychologists to explain cause-and-effect relationships in human behavior. The upshot appears to be that the logic of human behavior is not nearly as predictable as mathematical logic, but that the former prevails the vast majority of the time. The wants and needs of the human personality is what makes behavioral economics such a good explainer and predictor of economic events in much the same way that gravity so successfully explains many astrophysical matters, but is not the answer to every phenomenon that might be observed.

So to conclude, I congratulate Prof. Rodrik on a well-written book that makes its points nicely. The only thing I could ask is more of the same in greater schematic or analytical detail that would provide a taxonomy of analytical models arranged in their respective family trees and lines of inheritance and commonalities. It would be like creating a Venn diagram for each of the variants that he might want to consider. That might take some doing, but I think it would be well worth the effort. I am confident that real-world examples could be found to illustrate the main points of the discussion. Now that he has established that there are many models to describe economic behavior, there will be many readers who will be keen to see where he will go with this line of inquiry.
