That's me after Lant Pritchett declared that the "entire idea of evidence is bullshit" on panel @BlavatnikSchool 0n #PublicServiceSystem conference Image
Forgot to mention that the title of the panel was "What constitutes good evidence in systems research?"
Lant's position, for those who asked for context, is that the term evidence has been expropriated by a small cabal (you guessed right - the randomistas), and has been used as a mean to assert control & domination within academia
To talk about what constitutes evidence for policymaking is to implicitly accept premises that he rejects: that it is ontologically possible to build a body of knowledge of “what works” from disparate RCTs .

Excited to share a new working paper with Yotam Margait and @TamarMitts entitled “Media Ownership as Political Investment: The Case of Israel Hayom.” A draft of the paper can be found at cpb-us-w2.wpmucdn.com/web.sas.upenn.… Image
In 2007 Sheldon Adelson founded a new daily to counterbalance Israel’s news media’s “liberal bias”. Israel Hayom is a full-blown newspaper (not pamphlet). We ask – can a newspaper with known political slant, operating in competitive market, nonetheless affect voting behavior?
Losing $27M A YEAR on aggressive marketing, by 2010 Israel Hayom (IH) became the mostly widely read paper with 40% exposure! This figure is readership, not circulation. Even my mom reads IH. Image

I am truly excited to help launch the Penn Development Research Initiative (PDRI - pdri.upenn.edu), an interdisciplinary community of scholars @Penn whose research seeks to identify solutions to the challenges facing developing countries.
PDRI bridges 7 schools @Penn and brings together faculty and graduate students with interests in various aspects of international development including governance, education, health, environment, gender, urbanization and migration, labor markets, poverty, and economic growth.
PDRI seeks to strengthen the connections between development researchers @Penn and also expand our collaborations with development practitioners outside Penn. PDRI is well-positioned to support extramurally-funded research projects on diverse topics and in various settings.

Apropos the longest shutdown in US history, my paper "Border Walls and Smuggling Spillovers" with my awesome co-authors @austinlwright & @anna_getmansky was accepted today for publication at QJPS. Image
In this paper, we explore whether the construction of the border wall (see some figures) between Israel and the West Bank reduced cross-border illicit smuggling of stolen vehicles (80% of stolen cars are smuggled to chop shops in the WB) . ImageImage
for identification, we take advantage of the staggered construction: the barrier was initially built in the northern part of border, and only later extended to the south. pre-construction trends in theft are parallel, but post-construction we see divergence ImageImage

Apropos debates on the effectiveness of the Wall, @austinlwright, @anna_getmansky and I have completed an new draft of our paper ``Border Walls and Smuggling Spillovers.'' See bit.ly/2rSpRyo
We find that smuggling decreases in places protected by the wall and increases at similar rates in unprotected towns where the border wall has not yet been built. The Wall thus had little effect on overall crime, yet it had distributional consequences due to spatial displacement
We conclude: even when border walls raise smuggling costs, they do little to reduce cross-border smuggling if fortification is partial, demand for illicit goods is stable and smuggling can be displaced to neighboring regions with minimal transaction costs."

Responding to my offer, I have been approached by 18 students on the TT job market asking me to comment on their cover letter (12 male and 6 female). Here's a quick reflective thread of what I have learned. 1/
First, it is exciting to read all about the excellent and diverse work that ABDs are producing. Our discipline is heading in a positive direction. 2/
Your cover letter is not a research statement. It is unnecessary to go into very technical details of ur design. It is more important to show the bigger picture (research interest, research questions, methodological approaches, teaching priorities, productivity, recognition). 3/

Amir Levi, @hispeedtourist and I have a new policy paper, (HKS WP series) entitled "Does greater public transit access increase employment for the Israeli-Arab Population? A Preliminary Analysis" bit.ly/2AzpaRz Image
the study's starting point is an unprecedented resolution by the the Israeli gov to make large multi-sectoral investment to reduce economic gaps between Jews and Arabs. Read about resolution 922 at bit.ly/2O7HinL
Public transit has been identified as low-hanging fruit for investment. Gaps in in access are huge (see pic) and public transportation is not “politically sensitive”. Image
