My name is Trinh Pham, and I am an applied economist with research focusing on the intersection of development, labor, and environmental economics.
I am particularly interested in understanding the determinants of household livelihoods and resource allocation in low- and middle-income countries,
as well as the factors influencing educational decisions and labor market outcomes.
I am currently a tenure-track Assistant Professor at the Korea Development Institute (KDI) School of Public Policy and Management.
I received my PhD in Applied Economics from Cornell University in 2024. My doctoral research was recognized by the
Weiss Fund for Research in Development Economics and the Agricultural & Applied Economics Association.
We evaluate two randomized controlled trials in Bhutan testing whether near-peer mentoring can shift students’ educational preferences toward STEM and TVET pathways. Mentors provided personalized guidance, shared their ownexperiences, and offered information on admissions and labor market outcomes. The interventions significantly increased students’ interest and perceived knowledge, but had limited effects on actual applications or enrollment. In the STEM stream, limited follow-through appears linked to structural constraints such as academic selectivity and limited program capacity; for TVET, social stigma and parental skepticism likely
played a constraining role. These findings highlight the potential of light-touch, scalable mentoring to shape aspirations, while underscoring the need for complementary strategies to support behavior change and enable follow-through.
This paper reviews the feedbacks between structural transformation and
agriculture, and climate and the natural environment. The
longstanding development narrative often ignores nature’s influence
on factor productivity and stocks. We highlight missing linkages and
pose policy research questions regarding structural transformation
and environmental-economic feedback in low-income nations.
This paper provides a new explanation for ethnic disparities in education and health in Vietnam
by studying the relationship between frequent, small-scale adverse rainfall shocks and child human capital.
Exploiting plausibly random year-to-year variation in weather data that are linked to a longitudinal
household- and individual-level dataset over the period 2008–2017, I find that excess rainfall
during the annual typhoon season results in lower child subjective health status and school enrollment,
with disproportionate effects on children of ethnic minorities. The negative lagged effects on education
are concentrated in children at primary school start age, suggesting delaying children’s school entry is
a shock–coping strategy for poor ethnic minority households, albeit with potentially big negative long-run
effect on their child lifetime earnings. Estimates suggest that rainfall shocks can explain approximately 28%
of the observed ethnic gap in enrollment rates of children age 16–18 in the sample during the study period,
and most is due to heterogeneous effects of rainfall shocks among ethnic groups, not differences in exposure to rainfall shocks.
We combine nationally representative household and labor force survey data from 1992 to 2016 to provide
a detailed description of rural labor market evolution and how it relates to the structural transformation
of rural Vietnam, especially within the agricultural sector. Our study adds to the emerging literature on
structural transformation in low-income countries using micro-level data and helps to answer several
policy-related questions. We find limited employment creation potential of agriculture, especially for youth.
Rural-urban real wage convergence has gone hand-in-hand with increased diversification of the rural economy
into the non-farm sector nationwide and rapid advances in educational attainment in all sectors’ and regions’
workforce. Minimum wage laws seem to have played no significant role in increasing agricultural wages.
This enhanced integration also manifests in steady attenuation of the longstanding inverse farm size-yield
relationship. Farming has remained securely household-based and the family farmland distribution has remained
largely unchanged. Small farm sizes have not obstructed mechanization nor the uptake of labor-saving pesticides,
consistent with factor substitution induced by rising real wage rates. As rural households rely more heavily on
the labor market, human capital accumulation (rather than land endowments) have become the key correlate of
improvements in rural household well-being.

[1] Climate Change and Intersectoral Labor Reallocation in a Developing Country Weiss Fund Distinguished PhD Research Paper Award (NEUDC 2023, Harvard Kennedy School)
Using nearly three decades of Vietnamese data, I document the heterogeneous effects
of temperature changes on intersectoral labor reallocation across regions and demographics.
Extreme heat generally shifts workers from agriculture to non-agriculture in
both the short and long term. While all workers face similar probabilities of entering
informal non-agricultural jobs, younger individuals are more likely to secure formal
employment. In less globally integrated regions, extreme heat increases agricultural labor
shares and reduces consumption expenditure. These findings align with a model
of costly labor reallocation, emphasizing trade openness and intersectoral switching
costs as critical factors linking climate shocks to employment dynamics.
[2] Who Benefits from Industrialization? Labor Market Adjustments and Household Welfare in Vietnam
Leveraging the staggered roll-out of industrial zones in Vietnam and detailed household and individual survey data,
this paper evaluates how place‑based industrialization shapes labor markets and household welfare. Labor responses
are heterogeneous. Youth reduce labor force participation, increasing school enrollment and degree attainment.
Prime-age adults shift away from agricultural employment, with reductions largest among those less attached to
the sector, while hours remain unchanged for those who stay. Informal non-agricultural employment plays a key
role in spreading welfare gains beyond formal jobs, particularly for less-educated individuals and households.
These adjustments lead to broadly shared increases in labor income and household consumption. The findings
highlight the importance of informality, multi-job livelihoods, and intra-household labor coordination in
shaping the equitable distribution of industrialization's benefits in developing countries.
Anthropogenic climate change will likely intensify the negative environmental impacts of agriculture through powerful feedback loops.
This has important implications for development research, policy and R&D investment.
