Hais Txog
Kuv txoj haujlwm nyob ntawm qhov sib tshuam ntawm kev txhim kho kev lag luam, kev ua liaj ua teb, poj niam txiv neej, thiab kev ntsuas hauv cov teb chaws tab tom txhim kho. Kuv siv kev soj ntsuam tsev neeg loj thiab cov ntaub ntawv geospatial los kawm txog kev ua haujlwm ntawm tsev neeg, liaj teb, thiab kev lag luam, tshwj xeeb hauv tej chaw uas cov ntaub ntawv tsawg lossis nyuaj rau sau. Kuv tau txais kuv daim PhD ntawm Graduate Institute hauv Geneva thiab tau ua haujlwm nrog cov ntaub ntawv soj ntsuam ntawm IFPRI, IMF, thiab World Bank.
Kuv tsim Dollar Scholars, ib lub koom haum uas muab kev kawm nyiaj txiag raws li pov thawj rau cov neeg laus uas tej zaum tsis tau muaj kev nkag mus rau nws. Kuv kuj tau tsim nws lub vev xaib thiab kev xeem ntau hom lus.
Ua ntej kawm txog kev lag luam, kuv tau siv xya xyoo ua ib tug kws tshaj lij eSports, hu xov tooj rau Counter-Strike thiab Warcraft III kev sib tw los ntawm Seoul mus rau Monza txij xyoo 2004 txog 2011. Kuv tseem ua si Counter-Strike 2 thiab Overwatch 2, thiab ua raid ua bard hauv EverQuest.

Spreading the love around: how does agricultural labor demand respond to temporary weather shocks?
Across six countries, farm households lean heavily on family labor during droughts and unusually wet periods. Women-headed households are significantly more constrained.
Abstract
This is the first study to separately identify labor demand responses to both unanticipated droughts and periods of above normal rainfall for three forms of agricultural labor that are central to agricultural production: family, hired, and mutual exchange labor. I use a simple parcel‑level model with three labor types and monitoring costs to study how family labor is reallocated across parcels during drought. In six countries I find small but statistically significant decreases in the share of hired labor during droughts and during periods of above-normal rainfall, indicating a strong reliance on family labor during shocks. I find that farm households appear to lean heavily on exchange labor by using exchange labor more frequently during periods of above-normal rainfall. Due to the heavy reliance on family labor, household size and the gender of the household head are important moderating factors. Women-headed households appear to be significantly more constrained in how they apply labor on family farms. My findings underscore that these labor types are distinct in how they respond to temporary weather shocks. The results of my analysis have important implications for policies targeted at stimulating agricultural labor markets.

Assessing land area from above: evidence from Armenia
Ib qho kev sim randomized hauv kev tshawb fawb tsev neeg: kev taug qab cov teb chaws ntawm duab satellite siv sijhawm tsawg dua 42% piv rau kev ntsuas nrog GPS thiab txhim kho dua li kev kwv yees uas tus kheej qhia, txawm tias nws tsis raug zoo li GPS.
Abstract
Using primary data collected by the World Bank in Armenia as part of a randomized controlled trial, we evaluate the use of a satellite image tracing to measure agricultural land in the context of a household survey. Satellite tracing offers several benefits, including a large reduction in the cost of measuring land, the potential to measure more parcels of land, and improved security for survey enumerators. We find the satellite tracing approach yields consistent results, and requires 42% less time than measuring with GPS, and provides value-added over self-reported estimates. Due to the potential cost savings, and other non-trivial benefits, we suggest that land measurement via satellite image tracing offers significant value, though is not as accurate as land area estimates conducted with a handheld GPS.
Kev qhia ntawv
Nws yeej yog ib tug xibfwb zoo tshaj plaws uas kuv tau muaj ntawm American University. Nws ua txhua yam kom chav kawm siv cov piv txwv tiag tiag ntawm cov ntaub ntawv es tsis yog tsuas yog 'Sally muaj 4 lub txiv apples thiab Dave muaj 15 lub txiv kab ntxwv' xwb... Nws yog txhua yam uas ib tug xibfwb hauv tsev kawm qib siab yuav tsum muaj thiab ntau dua.
