https://estudiosdeeconomia.uchile.cl/index.php/EDE <p>Estudios de Economía is published, since 1973, two times a year by the Department of Economics at the University of Chile. Its purpose is to publish empirical as well as theoretical papers in every field of Economics. All papers must go through refereeing process by two anonymous referees. As part of our editorial policy, an answer regarding the status of a paper will not exceed two months from its reception. If that were not the case, the authors are free to send their paper for consideration for publication elsewhere.</p> en-US ede-econ@fen.uchile.cl (Rómulo A.

In this note, I show that despite this tension every link receiver in a Nash network serves as an efficient transmitter of information assuming a small degree of information decay. Thus, a strategic decision of every link sender, who always forms links with efficient link receivers for his own interest, does in part lead to a socially desirable outcome. I also show how this finding can potentially refine some results in the literature.

I document wide variation across municipalities. Relative mobility is correlated to the number of doctors, the number of students per teacher, and earnings inequality. Using a LASSO, I find that the share of students enrolled in public schools, the number of students per teacher, population density, and municipal budget are the strongest predictors of IGM. I also document within-country variability in how parental education is associated with other children’s outcomes Ercio Muñoz Copyright (c) 2025 Estudios de Economía https://estudiosdeeconomia.uchile.cl/index.php/EDE/article/view/81725 Wed, 19 Nov 2025 00:00:00 +0000 https://estudiosdeeconomia.uchile.cl/index.php/EDE/article/view/81726 This study analyzes the consumption elasticities of five key seasoning commodities in Indonesia: cooking oil, red onion, garlic, red chili, and cayenne pepper. A Linear Approximate Almost Ideal Demand System (LA/AIDS) model is employed, incorporating instrumental variables to address potential endogeneity. The results indicate that the unconditional income and own-price elasticities are inelastic, with income elasticities ranging from 0.74 to 0.75 and own-price elasticities from –0.77 to –0.94. No significant evidence of substitution or complementarity among the seasonings is found. Furthermore, elasticity remain similar before and after the COVID-19 pandemic, and across regions with different economic sizes. However, regions known for spicy cuisines demonstrate higher elasticities than those with milder culinary traditions.
