For 25 years, the so-called "Washington Consensus" -- comprising measures aimed at expanding the role of markets and constraining the role of the state -- has dominated economic development policy. As John Williamson, who coined the term, put it in 2002, these measures "are motherhood and apple pie, which is why they commanded a consensus."
Not anymore. Dani Rodrik, a renowned Harvard University economist, is the latest to challenge the intellectual foundations of the Washington Consensus in a powerful new book titled One Economics, Many Recipes: Globalization, Institutions, and Economic Growth. Rodrik's thesis is that though there is only one economics, there are many recipes for development success.
Rodrik has rendered a major service by stating so openly the claim of "one economics." A critic who made the same claim would be dismissed as paranoid, whereas Rodrik's standing creates an opportunity for a debate that would not otherwise be possible.
The "many recipes" thesis is that countries develop successfully by following eclectic policies tailored to specific local conditions rather than by following generic best-practice formulas designed by economic theorists. This challenges the Washington Consensus, with its one-size-fits-all formula of privatization, deregulated labor markets, financial liberalization, international economic integration and macroeconomic stability based on low inflation. But, while the many recipes thesis has strong appeal and empirical support, and suggests a spirit of theoretical pluralism, the claim of "one economics" is misguided, for it implies that mainstream neoclassical economics is the only true economics.
Part of the difficulty of exposing this narrowness is that there is a family split among neo-classical economists between those who believe that real-world market economies approximate perfect competition and those who don't.
Believers are identified with the "Chicago School," whose leading exponents include Milton Friedman and George Stigler. Non-believers are identified with the "MIT School" associated with Paul Samuelson. Rodrik is of the MIT School, as are Paul Krugman and Joseph Stiglitz. This split obscures the underlying uniformity of thought.
The Chicago School claims that real-world market economies produce roughly efficient (so-called "Pareto optimal") outcomes on which public policy cannot improve. Thus, any state intervention in the economy must make someone worse off.
The MIT School, by contrast, argues that real-world economies are afflicted by pervasive market failures, including imperfect competition and monopoly, externalities associated with problems like pollution and an inability to supply public goods such as street lighting or defense. Consequently, policy interventions that address market failures -- as well as widespread information imperfections and the non-existence of needed markets -- can make everyone better off.
None of this is about fairness, which is a separate issue. Indeed, neither school says that market outcomes are fair, because actual market outcomes depend on the initial distribution of resources. If that distribution was unfair, current and future outcomes will be unfair, too.
Chicago economists seem to believe that real-world outcomes are acceptably unfair and, more importantly, that attempts to remedy unfairness are too costly, because tampering with markets causes economic inefficiency. They believe that government intervention tends to generate its own costly failures because of bureaucratic incompetence and rent-seeking, whereby private interests try to steer policy to their own advantage.
MIT economists tend to espouse the opposite: Fairness is important, the real world is unacceptably unfair, and government failure can be prevented by good institutional design, including democracy.
These differences reflect the intellectual richness of neo-classical economics, but they provide no justification for the claim that there is one economics. On the contrary, heterodox economists like Thorsten Veblen long ago raised many of today's cutting-edge issues in neoclassical economics, including the role of social norms and the relationship between technological innovation and business cycles.
Heterodox economics includes core theoretical concepts that are fundamentally incompatible with neoclassical economics in either of its two contemporary forms. These concepts result in very different explanations of the real world, including income distribution and the determinants of economic activity and growth. Moreover, they often result in different policy prescriptions.
The late Robert Heilbronner viewed economics as "worldly philosophy." Just as philosophers are divided on the nature of truth and understanding, economics is divided on the workings of the real world. Paradigms should co-exist in economics, just as in other social sciences. Yet, in practice, the dominance of the belief in "one economics" has led increasingly to a narrow and exclusionary view of the discipline.
This reality is difficult to convey. One reason is that liberal neo-classical economists like Stiglitz and Krugman share values with heterodox economists, and shared values are easily conflated with shared analysis. Another reason is that heterodox and MIT School economists also often agree on policy, even if their reasoning is different. Finally, most people are incredulous that economists could be so audacious as to enforce one view of economics.
The "many recipes" thesis enriches neo-classical economics' contribution to the development debate, and many of its policy proposals will find support from heterodox economists. However, it fails to engage the deep intellectual divisions regarding economic development, trade, and globalization, because it refuses to admit the legitimacy of such disagreements.
By repeating the claim of "one economics," Rodrik inadvertently reveals the censorship embedded in contemporary economics. The great challenge is not to admit that there are many recipes, but rather to create space for other perspectives on economic analysis and policy.

As China steps up a campaign to diplomatically isolate and squeeze Taiwan, it has become more imperative than ever that Taipei play a greater role internationally with the support of the democratic world. To help safeguard its autonomous status, Taiwan needs to go beyond bolstering its defenses with weapons like anti-ship and anti-aircraft missiles. With the help of its international backers, it must also expand its diplomatic footprint globally. But are Taiwan’s foreign friends willing to translate their rhetoric into action by helping Taipei carve out more international space for itself? Beating back China’s effort to turn Taiwan into an international pariah
Typhoon Krathon made landfall in southwestern Taiwan last week, bringing strong winds, heavy rain and flooding, cutting power to more than 170,000 homes and water supply to more than 400,000 homes, and leading to more than 600 injuries and four deaths. Due to the typhoon, schools and offices across the nation were ordered to close for two to four days, stirring up familiar controversies over whether local governments’ decisions to call typhoon days were appropriate. The typhoon’s center made landfall in Kaohsiung’s Siaogang District (小港) at noon on Thursday, but it weakened into a tropical depression early on Friday, and its structure
Since the end of the Cold War, the US-China espionage battle has arguably become the largest on Earth. Spying on China is vital for the US, as China’s growing military and technological capabilities pose direct challenges to its interests, especially in defending Taiwan and maintaining security in the Indo-Pacific. Intelligence gathering helps the US counter Chinese aggression, stay ahead of threats and safeguard not only its own security, but also the stability of global trade routes. Unchecked Chinese expansion could destabilize the region and have far-reaching global consequences. In recent years, spying on China has become increasingly difficult for the US
Lately, China has been inviting Taiwanese influencers to travel to China’s Xinjiang region to make films, weaving a “beautiful Xinjiang” narrative as an antidote to the international community’s criticisms by creating a Potemkin village where nothing is awry. Such manipulations appear harmless — even compelling enough for people to go there — but peeling back the shiny veneer reveals something more insidious, something that is hard to ignore. These films are not only meant to promote tourism, but also harbor a deeper level of political intentions. Xinjiang — a region of China continuously listed in global human rights reports —
