DRAFT: A Competitive Market: A Python class for a competitive market equilibrium with linear supply and demand curves—equilibrium price, equilibrium quantity, producer surplus, consumer surplus, total surplus. Looks for input parameters giving the slopes of the demand and supply curves, plus the maximum willingness-to-pay of the most eager demander and the minimum opportunity cost of the most efficient supplier. Now ready to hand over to others for editing, tightening, and additions.

Richard Feynman: Math and Science: "How am I going to explain to you the things I don’t explain to my students until they are third-year graduate students? Let me explain it by analogy: The Maya Indians were interested in the rising and setting of Venus as a morning “star” and as an evening “star”—they were very interested in when it would appear. After some years of observation, they noted that five cycles of Venus were very nearly equal to eight of their “nominal years” of 365 days (they were aware that the true year of seasons was different and they made calculations of that also). To make calculations, the Maya had invented a system of bars and dots to represent numbers (including zero), and had rules by which to calculate and predict not only the risings and settings of Venus, but other celestial phenomena, such as lunar eclipses. In those days, only a few Maya priests could do such elaborate calculations. Now, suppose we were to ask one of them how to do just one step in the process of predicting when Venus will next rise as a morning star—subtracting two numbers. And let’s assume that, unlike today, we had not gone to school and did not know how to subtract. How would the priest explain to us what subtraction is?...
After hearing Ellora Derenoncourt rave about being a TA for Melissa Dell and her Econ 142: The History of Economic Growth, I have decided to go full parasite and stand up my own version of the course for the spring of 2020 here at U.C. Berkeley. Tell me what you think! Here are my notes so far:
Course to be at: Teaching Economics: https://delong.typepad.com/teaching_economics/econ-135.html
Econ 135: Economic Growth in Historical Perspective
This course examines the idea and reality of economic growth in historical perspective, beginning with the divergence between human ancestors and other primates and continuing through with forecasts for the 21st century and beyond. Topics covered include human speciation, language, and sociability; the discovery of agriculture and the domestication of animals; the origins and maintenance of gross inequality; Malthusian economies; the commercial and industrial revolutions; modern economic growth; international prosperity differentials; OECD convergence and East Asian miracles; the political economy of growth and stagnation; and the stubborn persistence of poverty.

Economics tends to view growth as a continuous and diffuse process: if one firm does not solve the problem of how to efficiently utilize resources, others will and drive the first out of business; if one technological vein plays itself out, energy will focus on others. These readings all argue different. They argue one side of a debate. They argue either that some unique and particular institutions and technologies matter a lot. What kinds of evidence not presented in these readings might lead you to come down on one or the other of the many, many sides in this debate—either on the side of economists' standard prior, or that in fact it is still other and still different institutions or technologies or simply the aggregate state of the economy that matters the most?

Harry Brighouse: Navigating the Need for Rigor and Engagement: How to Make Fruitful Class Discussions Happen: "Derek Bok... a passage that, ultimately, transformed my teaching:
Teaching by discussion can also seem forbidding because it makes instructors uncomfortably aware of their shortcomings. Lecturers can delude themselves that their courses are going well, but discussion leaders know when their teaching is failing to rouse the students’ interest by the indifferent quality of responses and the general torpor of the class. Trying to conduct a discussion with apathetic students is much like giving a bad dinner party...
Think that there are no such things as aggregate fluctuations generated by shifts in tastes and technologies? Think again. Look at the pattern of monthly payroll employment changes:
The unfortunate fact is that economists have gotten too good at making theories. In fact, the set of plausible and admissible economic theories is now dense in the space of possible conclusions: For every desired conclusion X, for every ε, and for a norm of "closeness" ||, there is a chain of theories T of increasing complexity indexed by n and a degree of theoretical complexity nδ such that:
(∀X)(∃nδ)(∃T(.))(∀n)(n > nδ -> | T(n) - X | < ε)
Or: with enough time and ingenuity and sweat, a theorist can prove that anything can be an equilibrium.
