This proof of concept study harnesses novel transdisciplinary insights to contrast two school-based smoking prevention interventions among adolescents in the UK and Colombia. We compare schools in these locations because smoking rates and norms are different, in order to better understand social norms based mechanisms of action related to smoking. We aim to: (1) improve the measurement of social norms for smoking behaviors in adolescents and reveal how they spread in schools; (2) to better characterize the mechanisms of action of smoking prevention interventions in schools, learning lessons for future intervention research. The A Stop Smoking in Schools Trial (ASSIST) …


Spanish California Missions: An Economic Success, Lynne Doti Jan 2019

Spanish California Missions: An Economic Success, Lynne Doti

Economics Faculty Articles and Research

Starting in 1769, the Spanish established missions in Alta California. A small band of soldiers, Franciscan priests and volunteers walked from Baja California to San Francisco Bay through semi-arid, scarcely populated land stopping occasionally to establish a location for a religious community. Usually two priests, a few soldiers and a few Indians from Baja California settled at the spot. Their only resources for starting an economy were themselves, a few animals and a nearby source of water. They attracted the local Indians to join the community and perform the work necessary to create a strong economy. After only a few …

Poverty Mapping Using Convolutional Neural Networks Trained On High And Medium Resolution Satellite Images, With An Application In Mexico, Boris Babenko, Jonathan Hersh, David Newhouse, Anusha Ramakrishnan, Tom Swartz

Mapping the spatial distribution of poverty in developing countries remains an important and costly challenge. These “poverty maps” are key inputs for poverty targeting, public goods provision, political accountability, and impact evaluation, that are all the more important given the geographic dispersion of the remaining bottom billion severely poor individuals. In this paper we train Convolutional Neural Networks (CNNs) to estimate poverty directly from high and medium resolution satellite images. We use both Planet and Digital Globe imagery with spatial resolutions of 3-5 m2 and 50 cm2 respectively, covering all 2 million km2 of Mexico. Benchmark poverty estimates come from …


Building A Better Model: Variable Selection To Predict Poverty In Pakistan And Sri Lanka, Marium Afzal, Jonathan Hersh, David Newhouse Sep 2015

Building A Better Model: Variable Selection To Predict Poverty In Pakistan And Sri Lanka, Marium Afzal, Jonathan Hersh, David Newhouse

Economics Faculty Articles and Research

Numerous studies have developed models to predict poverty, but surprisingly few have rigorously examined different approaches to developing prediction models. This paper applies out of sample validation techniques to household data from Pakistan and Sri Lanka, to compare the accuracy of regional poverty predictions from models derived using manual selection, stepwise regression, and Lasso-based procedures. It also examines how much incorporating publically available satellite data into the model improves its accuracy. The five main findings are that: 1) Lasso tends to outperform both discretionary and stepwise models in Pakistan, where the set of potential predictors is large. 2) Lasso and …


Institutions, The Rise Of Commerce And The Persistence Of Laws: Interest Restrictions In Islam And Christianity, Jared Rubin Jan 2011

Institutions, The Rise Of Commerce And The Persistence Of Laws: Interest Restrictions In Islam And Christianity, Jared Rubin

Economics Faculty Articles and Research

Why was economic development retarded in the Middle East relative to Western Europe, despite the Middle East being far ahead for centuries? A theoretical model inspired and substantiated by the history of interest restrictions suggests that this outcome emanates in part from the greater degree to which early Islamic political authorities derived legitimacy from religious authorities. This entailed a feedback mechanism in Europe in which the rise of commerce led to the relaxation of interest restrictions while also diminishing the Church's ability to legitimise political authorities. These interactions did not occur in the Islamic world despite equally amenable economic conditions.
