All Games Have Equilibria, M. Ali Khan, Arthur Paul Pedersen, Maxwell B. Stinchcombe

Publications and Research

Research on Nash equilibrium existence for infinite games has grown into a patchwork of technical preconditions and counterexamples. This paper presents a unified program in equilibrium theory by revising the predominant model of mixed strategies based on countable additivity. A game is specified by a nonempty set of players and, for each player, a nonempty action set and a bounded von Neumann-Morgenstern utility function. Every such game is shown to admit a Nash equilibrium in finitely additive mixed strategies. In addition, the equilibrium correspondence for any such game is shown to be nonempty, compact-valued, and upper hemicontinuous, and the same …

The Struggles For Equality And Democracy In Modern China: Which Was More Influential?, Angelina K. Lambros

Publications and Research

This paper analyzes the struggles for democracy and equality in modern China, from the fall of the Qing Dynasty to the Tiananmen Square movement. It considers which struggle was more influential, evaluating the recurring theme of a fight for democracy in China since the New Culture Movement, and a quest for social and economic equality that Mao and the Chinese Communist Party committed themselves to. Ultimately, the paper concludes that the struggle for democratic norms and institutions was always present among the Chinese people, but it did not succeed in pushing the government or the Party to adopt political reforms. …

Thinking Blue / Writing Red: Marxism And The (Post)Human, Stephen C. Tumino

Publications and Research

Thinking Blue/Writing Red interrogates contemporary culture across a range of texts, from the pandemic (‘Covid’ and ‘Trump Speak’) to high theory (Melville's narratives) and popular culture (Beyoncé's ‘Formation’ and Super Bowl performance, Twin Peaks , metamodern ‘cli-fi’ films). Inspired by Derrida’s idea of the secret, Tumino examines the significance of social movements (Black Lives Matter, Occupy, alter-globalization) and naïve art (Darger, Ryden) to argue that these texts speak of the secrets that capitalism cannot speak. Contending that the cultural surfaces narrate only the ‘nonsecret,’ that to see the social logic of the culture one must dig into what Bruno Latour …

Circular Economy: The 4rs Reduce-Reuse-Recycle-Recover, Kevin Hom

Publications and Research

This article summarizes the lecture presented at the Net Built 2024 conference. The lecture addresses the unsustainability of the current linear economy, characterized by the "take, make, dispose" model, in light of environmental challenges. The inefficiencies of this system lead to increased energy consumption, elevated CO2 emissions, and the exacerbation of climate change. It examines the current state of design and construction with respect to climate change and sustainable resource management. Additionally, the lecture introduces a methodology that integrates technologies and design philosophies capable of driving significant positive change. By advocating for a transformative approach to the expected lifetime of …

After The Cambridge Controversies: Reflections Old And New, Harvey Gram

Publications and Research

Perfect foresight is a consequence of applying the Pontryagin Maximum Principle to the analysis of an intertemporal general equilibrium. For this reason, the capital theory controversy ended in an intellectual impasse. The critique of mainstream theory largely ignored the perfect foresight entailments of intertemporal equilibrium analysis, while its defenders, with notable exceptions, too often failed to acknowledge this implication of the technique of dynamic programming. From this standpoint, the long debate over the existence or non-existence of an aggregate production function is secondary. This leaves open the theoretical question of how to proceed with an analysis of the actual dynamics …

Shocks To Aggregate Demand And Aggregate Supply In The Midst Of Covid-19, Anna M. Gellerman

Publications and Research

COVID-19 sent shockwaves throughout the economy, changing the amounts of goods and services distributed and altering the demand. This article discusses the negative demand shock and adverse supply shock that the U.S. economy faced in 2020, and the policies that the government implemented to reverse these effects.

The End Of Zero Returns And The Last Dollar: Can New York State Create A Collective Store Of Value, Crowdsource Wealth, And Fund Its Colleges And Universities Using Cryptocurrency?, Edward Lehner

Publications and Research

This brief personal statement, citing the previous work of the Bronx Community College Cryptocurrency Research Laboratory (BCC Lab), advocates for a private New York State Money to fund New York State’s public higher education. Attempting to shed most of the academic language and the formalities of research-driven writing, this short statement frames two distinct arguments. The first contention is that New York State residents need a means by which to store value outside of the traditional banking and financial systems due to massive Federal Reserve printing that is centered primarily on rescuing fledgling Wall Street profits and mitigating reckless businesses …

Teoria Da Crise E A Queda Da Taxa De Lucro, David Harvey

Publications and Research

Abstract:

David Harvey’s article argues against the importance given to the law of the tendency of the rate of profit to fall (TRPF), suggest­ing that Marx derived the « law » under « draconian » assumptions and that Engels was far more enthusiastic about it than Marx, who never went back to the theory later in his life despite its evident incompleteness. Therefore, he argues, we should not take his the­oretical conclusions too far. In his view, Marx perceived crises as momentary and violent eruptions that resolve the existing contra­dictions which can be considered as opportunities of capitalist re­construction rather …

Insatiability And Crisis: Using Interdisciplinarity To Understand (And Denaturalize) Contemporary Humans, Sean P. Macdonald, Costas Panayotakis

Publications and Research

This chapter illustrates how collaboration between different social sciences can encourage students to think critically about prevailing assumptions regarding human nature. Both the chapter and the pedagogical experience on which it is based investigate the distinctive type of human created by capitalist society. In so doing, it takes a heterodox approach to analyzing the concept of an insatiable human nature through a case study that invites students to critically assess this perspective. This discussion then leads to an investigation and critique of traditional neoclassical Economic assumptions about human behavior, which forms the basis for a case study on the causes …

Six Titans Of The Cambridge School: A Review Article, Harvey Gram

Publications and Research

Six volumes in the Great Thinker in Economics Series were chosen by the Editors for this review, which focuses on The Cambridge School of Economics, so very different from the mainstream theory of general economic equilibrium which gives formal expression to Lionel Robbins’ famous definition of the subject as the allocation of scarce means among alternative uses. In recognition of a distinct Cambridge School, the authors of these volumes present a variety of arguments within which three overlapping themes can be discerned: the relationship between ethics and economics; the role of stocks and flows in economic analysis; and the epistemic …
