Identification and Estimation of Undetected COVID-19 Cases Using Testing Data from Iceland

Aspelund, Karl M. - 2020

In the early stages of the COVID-19 pandemic, international testing efforts tended to target individuals whose symptoms and/or jobs placed them at a high presumed risk of infection. Testing regimes of this sort potentially result in a high proportion of cases going undetected. Quantifying this...

Peer Effects in European Primary Schools : Evidence from PIRLS

Ammermueller, Andreas - 2006

We estimate peer effects for fourth graders in six European countries. The identification relies on variation across classes within schools. We argue that classes within primary schools are formed roughly randomly with respect to family background. Similar to previous studies, we find sizeable...

The gift of moving : intergenerational consequences of a mobility shock

Nakamura, Emi; Jósef Sigurdsson; Jón Steinsson - 2016

We exploit a volcanic “experiment" to study the costs and benefits of geographic mobility. We show that moving costs (broadly defined) are very large and labor therefore does not flow to locations where it earns the highest returns. In our experiment, a third of the houses in a town were...

Farm productivity and market structure : evidence from cotton reforms in Zambia

Brambilla, Irene - 2005

"This paper investigates the impacts of cotton marketing reforms on farm productivity, a key element for poverty alleviation, in rural Zambia. The reforms comprised the elimination of the Zambian cotton marketing board that was in place since 1977. Following liberalization, the sector adopted an...

Energy, Groundwater, and Crop Choice

Burlig, Fiona; Preonas, Louis; Woerman, Matt - National Bureau of Economic Research - 2021

Groundwater is a key resource for agricultural production globally. Increasingly rapid aquifer drawdowns--as well as the policies intended to increase their sustainability--increase costs to agricultural producers, with unknown consequences. This paper provides the first large-scale empirical...

Business Cycle during Structural Change : Arthur Lewis' Theory from a Neoclassical Perspective

Storesletten, Kjetil - 2019

agriculture declines while labor productivity increases in agriculture more than in other sectors. We construct a unified theory … simultaneous decline and modernization of agriculture. As capital accumulates, agriculture becomes increasingly capital intensive … as modern agriculture crowds out traditional agriculture. Structural change accelerates in booms and slows down in …

Gravity and Comparative Advantage : Estimation of Trade Elasticities for the Agricultural Sector

Heerman, Kari E.R. - 2018

In this paper, a structural gravity model is presented which features intra-sector heterogeneity in agricultural productivity systematically linked to land and climate characteristics. The "systematic heterogeneity" (SH) gravity model predicts that countries with similar land and climate...
