[latexpage]In englishComparto aquí un análisis preliminar de los efectos de la ley de alquileres, sancionada en 2017, sobre los valores de alquiler. Esta ley, declarada inconstitucional en Mayo de este año, libró a los inquilinos del pago de la comisión inmobiliaria, al tiempo que también impuso una comisión máxima a ser pagada a las inmobiliarias.
Identification with DAGs: Introduction with simple simulations
En español
In this post I want to share with you some introductory ideas on how Directed Acyclical Graphs (DAGs) are used for causal identification. I am also sharing a few (Stata based) numerical simulations (here), that can be illustrative of their use in a regression application.
The DAG approach has been around for at least a decade now, and is described in extent in the excellent book by Pearl and Mackenzie (2018)’s “The Book of Why”. There’s so much going on in the book that I will be writing more about it in a future post.
Notes on Matching in Entrepreneurial Finance Networks
español We are glad our paper (with Virginia Sarria Allende and Gabriela Robiolo) went out in Venture Capital : A International Entrepreneurial Finance Journal. A working paper version is available here. Here are some brief comments on the ideas, the econometrics, and data approach: In the paper we study the “matching” between investors and startups in the entrepreneurial finance market. Broadly speaking, we are concerned with the question of who will invest in who, and in the role played by (social, professional) networks in the explanation. Specifically, we show evidence on a simple idea: due to information related frictions in the entrepreneurial finance market, being closer in the network of connections actually matters for matching. Being closer increases not only the attractiveness of a prospective match, but also makes observable attributes more attractive. But “being closer” has a particular interpretation here. Our measured networked connections, are not the typical social (or follower) style of connections. We recognize a link if there is information that you have worked, invested, mentored, etc. a common startup or organization in the past. So we could say that these are really costly (or “signally meaningful”, in Spence’s sense) connections. For founders (or prospective investors alike)…
