The prediction of protein sub-cellular localization is an important step toward elucidating protein function. For each query protein sequence, LocTree2 applies machine learning (profile kernel SVM) to predict the native sub-cellular localization in 18 classes for eukaryotes, in six for bacteria and in three for archaea. The method outputs a score that reflects the reliability of each prediction...
Lack of access to nutritious and affordable food has become an important public policy issue in the U.S.: various interest groups are seeking to reverse a trend whereby certain areas lack larger, full-service grocery stores that provide “higher” quality foods. Based on game-theoretic findings suggesting that lack of food access can be an equilibrium outcome, we specify a model relating access t...
The Economics of Risky Health Behaviors Risky health behaviors such as smoking, drinking alcohol, drug use, unprotected sex, and poor diets and sedentary lifestyles (leading to obesity) are a major source of preventable deaths. This chapter overviews the theoretical frameworks for, and empirical evidence on, the economics of risky health behaviors. It describes traditional economic approaches e...
Sustainable agricultural practices (SAPs) that lead to an increase in productivity are central to the acceleration of economic growth; this will alleviate poverty and help to overcome the recurrent food shortages that affect millions of households in Africa. However, the adoption rates of SAPs remain below expected levels. This paper analyzes the factors that facilitate or impede the probabilit...

This study evaluates the potential impact of improved agricultural technologies on smallholders’ crop productivity and welfare. We use household-level data from Ethiopian Rural Household Survey collected by IFPRI in 1989-2009. The survey covers around 1500 rural households drawn from four regions and 15 rural villages. Endogenous treatment effect model is employed to account for the selection b...
How effective adaptation practices in response to climate change are is a crucial question confronting farmers across the world. Using detailed plot-level data from a specifically designed survey conducted in 2013, this paper investigates whether there are productive benefits for farmers who adapt to climate change in Pakistan. The impact of implementing on-farm adaptation strategies is estimat...
Mass media plays a crucial role in information distribution and thus in the political market and public policy making. Theory predicts that information provided by mass media reflects the media’s incentives to provide news to different types of groups in society, and affects these groups’ influence in policy-making. We use data on agricultural policy from 67 countries, spanning a wide range of ...
The theory of the Samaritan’s dilemma posits a downside to private or public charity: recipients may begin to rely on free aid instead of their own efforts. An important application is government aid. When the government acts as an “insurer of last resort”, potential beneficiaries may reduce private insurance coverage and instead rely on the government to bail them out. This phenomenon can incr...
This paper examines the contribution of women’s labour input to productivity and efficiency in crop farming using a large survey dataset of 1,839 households from 16 villages in two agroecological regions of Bangladesh. Results reveal that female labour accounts for a substantial 28% of total labour use (mainly supplied from the family) and contributes significantly to productivity as well as te...
