Research

My main research fields are the Economics of Technical Change and Economic Growth; Information and Economics; and Bayesian Econometrics. 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

1.  “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. “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 factor market.

3. “The Persistent Statistical Structure of the US Input-Output Coefficient Matrices: 1963-2007,” with Luis Daniel Torres Gonzalez,  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.

 

Working papers

1. “A Bayesian Multiple Technological Frontier Estimation in the Probabilistic Induced Technical Change Model: OECD Countries from 1968-2009,” Under Review 

I develop a new Bayesian cluster identification model to estimate the multiple technological frontiers for the OECD economies and explains a stylized fact of economic development of advanced economies from a low-wage, labor-intensive economy to a high-wage, capital-intensive economy.

2. “Arbitrage, Information, and the Competitive Organization of Distributions of Profitability,” with Paulo dos Santos, Under Review.

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.
