The Janeway Institute: Reimagining Economics through Keynesian Principles, Finance Integration, and Empirical Rigor

Bill Janeway, a co-founder of the Institute for New Economic Thinking (INET), discusses the inspiration and mission behind the creation of the Janeway Institute at Cambridge, a successor to the Cambridge INET. His intellectual journey began as a research student at Cambridge, deeply influenced by John Maynard Keynes's vision of integrating politics and finance into economics to understand the real world. His PhD thesis on British economic policy during the Great Depression (1929-31) instilled three core lessons: the deep interdependence of the financial system and the real economy, the inherent fragility of this complex system, and the pervasive "radical uncertainty" under which all economic decisions are made. These insights led him to reject mainstream academic economics, which he felt had become detached from reality through "bastard Keynesianism" and the neoclassical model's reliance on assumptions like full employment and rational agents, prompting his 35-year venture capital career.

Janeway recounts his return to academia after the dot-com bubble, where his Cambridge-honed understanding of financial fragility allowed him to liquidate his tech portfolio effectively. This experience, coupled with the 2008 Global Financial Crisis, underscored the urgent need for a new economic paradigm. He joined INET, which sought to establish research centers addressing the shortcomings of received doctrine. The Cambridge INET, with substantial funding from INET and local sources, successfully fostered a consensus research program within the Cambridge economics faculty, focusing on themes like uncertainty, policy translation, the social context of market participants, and crucially, the integration of finance and economics. This success led to the endowment of the new Janeway Institute, ensuring the perpetuation and evolution of this mission.

The institute champions an interdisciplinary approach, collaborating with history, public policy, and data science departments to explore economic history, policy implications, and empirical methodologies. Janeway highlights a broader "credibility revolution" in economics, emphasizing a shift towards empirical work and teasing out causal relationships, moving beyond theoretical abstractions. He cites the Nobel laureates Stiglitz, Spence, and Akerlof as pioneers in undermining the "rational representative agent" microfoundations. His own work, particularly his "three-player game" model of innovation, emphasizes the complementary roles of the state (as funder and first customer), financial speculation (bubbles), and entrepreneurs in driving technological and economic transformation, drawing parallels from railroads to the internet.

Looking forward, the institute aims to tackle grand challenges like climate change, viewing it as an "existential crisis" that can legitimize government intervention akin to wartime mobilization, but with life-saving rather than destructive outcomes. However, he cautions that the "devil is in the distributional consequences" of both the event and the response, critiquing simplistic market-based solutions like a universal carbon tax. Janeway also expresses concern about the current financial bubble in crypto, meme stocks, and tech giants, suggesting it may be "sponsored by the central bank" through negative real risk-free interest rates, predicting a disruptive end when monetary policy shifts. The institute's enduring mission is to foster a more realistic, integrated, and empirically grounded understanding of economic dynamics to better navigate such complexities.

"the deep interdependence of the financial system and the real economy of employment consumption investment savings that the money is not a bail money is not neutral what goes on in the financial system influences what goes on in the real economy and it feeds back from the real economy to the financial system"

"that interactive interdependent complex system is fragile it does not we cannot depend upon it to to to sit in a state of stable equilibrium"

"every participant individual and institutional is operating... under conditions of more or less radical uncertainty about what the future consequences of decisions that have to be made today"

"bastard keynesianism you took keynes to say we can now assume that all resources are fully employed at all times and then that allows us to return to the perfectly competitive markets of microeconomics"

"i've seen this movie before i know how it ends"

"the shortcomings of mainstream neoclassical economics but also of the opportunity that was being opened up by the impact of the global financial crisis in the great recession"

"the fact that market participants are not autonomous independent agents they operate in a contact a social networked context and of course above all the integration of finance and economics that has been forced on both disciplines by the real world"

"macroeconomics had cut itself off and extracted itself from any connection with the financial system any exposure to that what happened in the banking system the capital markets might have an influence on really real economic factors and had rooted itself in a quote micro foundation based on the the the fantastical abstraction of the rational representative agent"

"the first really important and very broad quantifiable observable aspect of how economics has evolved in the last decade has been the shift towards empirical work the credibility revolution"

"the three-player game because there's a third player in that game whose history and role in financing innovation actually goes back before an active if you like hamiltonian state reach substantial scale and that is financial speculation"

"the bubble that's going on between crypto and the meme stocks and the incredible valuation of the tech giants may be the first bubble that not deliberately but quite directly has been sponsored by the central bank"

"in one dimension the threat the reality of climate change the necessity of response does have the economic and political significance weight of a major war it is an existential crisis which can legitimize government programs policies interventions that under quote normal circumstances would be off the table"
