We study some recent developments and challenges in the empirics of the effects of social networks. We focus in particular on researchers' ability to make policy recommendations based on a standard linear econometric model. We examine the potential compatibility between this type of econometric...

This paper examines the econometric causal model for policy analysis developed by the seminal ideas of Ragnar Frisch and Trygve Haavelmo. We compare the econometric causal model with two popular causal frameworks: Neyman-Holland causal model and the do-calculus. The Neyman-Holland causal model...

We estimate the causal impact of a 2018 zoning reform that banned new short-term rental registries in some parts of Lisbon. The short-term rental licence expires when the house is sold, hence the ban removes the option value of short-term renting a property. We rely on two administrative data...

The urgency of the two crises, especially the COVID-19 pandemic, revealed the inadequacy of traditional statistical datasets and models to provide a timely support to the decision-making process in times of volatility. Drawing upon advances in data analytics for public policy and the increasing...

We explore the association between urban density and pupil attainment using three cohorts of pupils in schooling in England. Although as widely recognised attainment in dense urban places is low on average, this is not because urban environments disadvantage pupils, but because the most...

Economic regions, such as urban agglomerations, face external demand and price shocks that produce income risk. Workers in large and diversified agglomerations may benefit from reduced wage volatility, while firms may outsource the production of intermediate goods and realize benefits from...

This paper investigates certain issues of economic and ethnic segregation from the perspective of children in the three metropolitan regions of Sweden by using a relative new operationalization of the neighbourhood concept. Neighbourhoods are clustered by population share of visible immigrants...

This paper takes a fresh look at child poverty at the neighbourhood level in the three metropolitan regions of Sweden using unique data for 1990, 1996 and 2002. We find that the number of neighbourhoods with high child poverty rates is much larger in 2002 than in 1990, but also that most poor...

This paper studies gross worker flows to explain the rising informality in Brazilian metropolitan labor markets from 1983-2002. This period covers two economic cycles, several stabilization plans, a far-reaching trade liberalization, and changes in labor legislation through the Constitutional...
