Jangho Yang



I have a wide range of teaching experience, from mentoring and tutoring undergraduate students in their research, to teaching introductory economics and graduate-level econometric courses. My teaching has been recognized by The New School, and I have had the honor of receiving the “Outstanding Student Teaching Award” in 2016, recognizing the best student teacher of the year. In 2017, I was awarded the “Eugene Lang Social Science Fellowship,” a grant awarded to an outstanding Ph.D. student to provide supervision to an advanced undergraduate student to write a high-quality research paper.

  • Lab Instructor, Advanced Econometrics, New School for Social Research

Syllabus design, problem set design, learning goals, assessment, teaching Bayesian econometric models using R (Fall 2016, Spring 2017, Fall 2017)

Example problem sets










  • Teaching Assistant, Intro to Political Economy, taught by Prof. Paulo dos Santos, Eugene Lang College of Liberal Arts (Fall 2016)

Held weekly lab session, graded exams, taught basic concepts of political economy, microeconomics, and macroeconomics.



My main research fields are the Economics of Technical Change and Economic Growth; Firm-Level Data Analysis; Bayesian Econometrics; and Information Theory. The following is the list of published journal articles, book chapters, and working papers. I also include some ongoing projects in Work in Progress section.

Journal Articles

Economics Journals

1. Yang, J.  “Information Theoretic Approaches in Economics, The Journal of Economic Surveys, 2017

I review key elements of information theory, focusing on notions and applications of entropy and statistical equilibrium in economics, paying particular attention to how entropy concepts open up a new front line for economic research.

2. Yang, J. and Torres, D. “The Persistent Statistical Structure of the US Input-Output Coefficient Matrices: 1963-2007,”  Economic Systems Research, 2019

We report on the persistent statistical patterns of the US Input-Output tables and show that the inter-industry relations are stable in the US economy over the past 5 decades.

Physics Journals

1. Yang, J. “A Quantal Response Statistical Equilibrium Model of Induced Technical Change in an Interactive Factor Market: Firm-Level Evidence in the EU Economies,” Entropy, 2018

I report on a persistent pattern of technical change at the firm level and analyze firms’ the rate of cost reduction (the growth rate of TFP) by using a maximum entropy model with the constraints on agent’s quantal response and the dynamics of the factor market.

2. Yang, J. and Carro, A. “Two Tales of Complex System Analysis: ABM and MaxEnt”,  EPJST, forthcoming.

We argue in this paper that maximum entropy modeling and agent-based modeling can complement each other, providing a powerful conceptual/empirical tool for the analysis of complex economic problems.

Working papers

1. Yang, J. “Information-Theoretic Model of Induced Technological Change: Theory and Empirics”,  Under Review.

I develop an information-theoretic model of Induced Technical Change where payoff-maximizing agents are exposed to a positive degree of uncertainty in adopting new technology due to unobserved cost factors. The derived equilibrium of the model comes in the form of a non-degenerate probability distribution that defines the distance of productivity growth from the potential maximum growth on the innovation possibility frontier, often called Technical Inefficiency Function (TIF) in the frontier estimation literature. I test the model using KLEMS data and show that the gamma TIF well explains the productivity deviation of EU industries from the theoretical frontier.

2. dos Santos, P. and Yang, J. Arbitrage, Information, and the Competitive Organization of Profitability Distributions”, R&R.

We report on the easily reproducible finding that the profitability of enterprises has a persistent cross-sectional distribution across a number of advanced economies. We show that the asymmetric Laplace distribution with the Pareto tails can be a good model for this pattern and discuss its economic implications based on the arbitrage seeking behavior of firms.

3. Yang, J., Torsten Heinrich, Julian Winkler, François Lafond, Pantelis Koutroumpis, and Doyne Farmer. Measuring Productivity Dispersion: a Parametric Approach Using the Levy Alpha-Stable Distribution.”

We propose to model the distributions of labor productivity using the four-parameter Levy stable distribution, a natural candidate deriving from the generalized Central Limit Theorem. We show that it is a better fit than several standard alternatives, and is remarkably consistent over time, countries and sectors. The distributional approach allows us to test different measures of dispersion and find that productivity dispersion has slightly decreased over the past decade.

4. Ilan Strauss & Yang, J., The Global Investment Slowdown: Corporate Secular Stagnation and the Draining of the Cash Flow Swamp.”

The investment slowdown in advanced economies reflects demand-side `corporate secular stagnation’, defined as a chronic excess of cash flow over weak investment opportunities. Consequently, firms increasingly do not use the external sector for net `borrowing’, but instead to `release’ in net excess funds to shareholders, bondholders, and creditors. We use this tendency as a proxy for corporate secular stagnation. Results from our Bayesian hierarchical model find that supply-side impediments to investment are largely absent. Nearly two-thirds of the yearly variation in investment rates between 1994-2017 can be explained by an increase in the proportion of firms who are net external `releasers’ of funds.
