Intuitive Mathematical Economics Series. General Equilibrium Models and the Gradient Field Method

Enviado por administrador el

General equilibrium models are typically presented with mathematical methods, such as the Edgeworth Box, that do not easily generalize to more than two goods and more than two agents. This is fine as a conceptual introduction, but it may be insufficient in the “Big-Data Machine-Learning Era”, with gigantic databases filled with data of extremely high dimensionality that are already changing the practice, and perhaps even the conceptual basis, of economics and other social sciences. In this paper present what we call the “Gradient Field Method” to solve these problems.

Argentina, COVID-19 y el Leviatan

Aunque Hobbes promovió la idea de un gobernante absoluto en el siglo XVII, su teoría encuentra un fértil terreno de aplicación en la actual pandemia. Está claro que hay valor en la autoridad porque nos ofrece protección; pero no hay nada gratis, para recibir protección es necesario aceptar cierto grado de sumisión, de pérdida de nuestra libertad.

The International Politics of Superheroes

Enviado por jogarcia@ucema… el

Follow your favorite caped crusaders (and foes) to learn about the current world order. Mariano Turzi explains the main theories of international relations through Batman, Two-Face, and the Justice League. The Hulk illuminates Russia's foreign policy and Aquaman sheds light on climate change. The X-Men experience the same dramas as refugees and Tony Stark personifies modern warfare. How is Spiderman like the UN and Wonder Woman's soft power comparable to the European Union? You will learn about globalization through Flash and about American hegemony with Superman and Captain America.

The Productive Efficiency of Science and Technology Worldwide: A Frontier Analysis.

Enviado por jogarcia@ucema… el

We are interested in how codified knowledge is produced around the globe (which inputs are used to produce scientific articles and patented inventions) and the efficiency of the process (how do the best performers produce more with the same inputs or produce the same with less inputs). Using a Data Envelopment Analysis (DEA) efficiency frontier approach, we aim to determine which countries are more efficient at producing codified knowledge. We proxy knowledge production by publications and patents, obtained through human (researchers) and non-human (R&D expenditure) resources.
