Interference across competing firms in RCTs can be informative about market structure. An experiment that subsidizes a random subset of traders who buy cocoa from farmers Sierra Leone illustrates this idea. Interpreting treatment-control differences prices and quantities purchased through model Cournot competition reveals differentiation between is low. Combining result with quasi-experimental ...

The Green Revolution, which bolstered agricultural yields and economic well-being in Asia Latin America beginning the 1960s, largely bypassed sub-Saharan Africa. We study first randomized controlled trial of a government-implemented input subsidy program (ISP) Africa intended to foment Revolution. find that this temporary for Mozambican maize farmers stimulates Revolution technology adoption le...

The hypereosinophilic syndrome (HES) is a group of rare disorders characterized by persistently high peripheral blood eosinophiles (≥ 1.5x109/L), and related signs or symptoms organ involvement without secondary causes. Eosinophilia with recurrent genetic abnormalities (PDGFRA/B, FGFR1) comprises minority these patients. In this report, we aimed to point out case 4q12 deletion whose diagnosis t...

We propose a spatial disaggregation tool to help researchers make the best use of aggregated data in studies of land use. The proposed approach uses parcel-level agricultural data in conjunction with biophysical processes to break down agricultural regional data to the pixel level. It is a two-step procedure. First, we estimate a landuse model using a multinomial logit model. Second, we disaggr...

This paper measures the economic impact of climate change on US agricultural land by estimating the effect of random year-to-year variation in temperature and precipitation on agricultural profits. The preferred estimates indicate that climate change will increase annual profits by $1.3 billion in 2002 dollars (2002$) or 4 percent. This estimate is robust to numerous specification checks and re...

This paper presents a synthesis of the main theoretical and empirical contributions that analyse production choices of farm households living and operating in developing countries. The review is particularly concerned with recent micro-economic contributions that highlight the trade-off farm households typically face, between full-income risk and expected return, while making production decisio...

Recent interest in horizontal symmetry model building has been driven mainly by the large top mass and hence strong hierarchy in quark masses, and the possibility of appropriately constrained soft squark mass matrices, in place of an assumed universality condition, for satisfying the relevant FCNC constraints. Here we present the rst successful SUSY-SU(5) model that has such a feature. The hori...

The molecular pathogenesis underlying the primary myelofibrosis (PMF) progression to acute myeloid leukemia (AML) is still not well defined. The involvement of microRNA (miRNA) is actually helping to shed light on an important issue in the occurrence of myeloproliferative neoplasms (MPNs). However, the role of intronic miRNA, derived from the intron regions of gene transcripts, has never been r...
