Redistributive land reforms, agricultural productivity, and structural change: New cross‐national evidence

American Journal of Agricultural Economics, EarlyView.
Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

How does the Kids SIPsmartER program impact the sugar‐sweetened beverage intake of students: An investigation beyond total treatment effect in randomized controlled trial

American Journal of Agricultural Economics, EarlyView.
Abstract This study develops and empirically estimates a structural framework to decompose the causal pathways of multilevel behavioral interventions targeting adolescent health behaviors. We apply this framework to the Kids SIPsmartER (KSS) program, a 6‐month, school‐based intervention evaluated through a clustered randomized controlled trial in rural

Multidimensional delta-shock waves and the transportation and concentration processes

, 2008
{\it $δ$-Shock wave type solutions} in the multidimensional system of conservation laws $$ ρ_t + \nabla\cdot(ρF(U))=0, \qquad (ρU)_t + \nabla\cdot(ρN(U))=0, \quad x\in \bR^n, $$ are studied, where $F=(F_j)$ is a given vector field, $N=(N_{jk})$ is a given tensor field, $F_j, N_{kj}:\bR^n \to \bR$, $j,k=1,...,n$; $ρ(x,t)\in \bR$, $U(x,t)\in \bR^n$.

Lost in aggregation? On the importance of local food price data for food poverty estimates

American Journal of Agricultural Economics, EarlyView.
Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Using pre‐ and post‐entry data to identify the effect of ethanol plant entry on the spatial pattern of corn prices: A study in Indiana

American Journal of Agricultural Economics, EarlyView.
Abstract We estimate the long‐run effect of ethanol plant entry on local corn prices using a long‐horizon difference‐in‐differences framework that combines matching with fixed effects while explicitly accounting for treatment intensity and spatial heterogeneity.

Prediction of High⁃Angle⁃of⁃Attack Aerodynamics for Flying⁃Wing Configurations Using Curvature⁃Corrected Turbulence Models

Nanjing Hangkong Hangtian Daxue Xuebao
Small-aspect-ratio flying-wing configurations and delta wings exhibit similar aerodynamic characteristics at high angles of attack. Both rely on leading-edge vortices to provide nonlinear lift， and they share common challenges such as sudden shifts in ...
