On Solvability of a Generalized Nonlinear Variational-Like Inequality

open access: yesJournal of Inequalities and Applications, 2009
A new generalized nonlinear variational-like inequality is introduced and studied. By applying the auxiliary principle technique and KKM theory, we construct a new iterative algorithm for solving the generalized nonlinear variational-like inequality. By

On Gap Functions for Quasi-Variational Inequalities

open access: yesAbstract and Applied Analysis, 2008
For variational inequalities, various merit functions, such as the gap function, the regularized gap function, the D-gap function and so on, have been proposed.

Minty variational inequalities, increase-along-rays property and optimization [PDF]

open access: yes
Let E be a linear space, K E and f : K ? R. We put in terms of the lower Dini directional derivative a problem, referred to as GMV I(f ,K), which can be considered as a generalization of the Minty variational inequality of differential type (for short ...

Causal analysis of trade loss from pathogens: A global study of foot and mouth disease impacts on meat exports

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Our general interest is in global trade loss from livestock pathogens, specifically exports. We adopt a causal inference approach that considers animal disease outbreaks over time as non‐staggered binary treatments with the potential for switching in (infection) and out of treatment (recovery) within the sample period. The outcome evolution of

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

open access: yesAmerican 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.

Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Firm turnover under asymmetric information: Tanzania's agro‐dealer sector

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract We study firm turnover (i.e., entry and exit) and its consumer implications in a market characterized by asymmetric information. Using a three‐round census of agro‐dealers in Tanzania's Morogoro Region, we document annual firm entry and exit rates of 33% and 17%, respectively.

Helping financially under‐resourced unmarried mothers move forward and flourish: Feasibility findings from an innovative coaching‐centered place‐based initiative

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Longer‐duration, holistic, cohort‐based, coach‐led interventions may be particularly effective in promoting both economic health and emotional well‐being among unmarried mothers living in economically disadvantaged neighborhoods. Aligning with the 1999 Centers for Disease Control (CDC) framework for program evaluation, this study presents a ...

The Made‐in‐Africa Evaluation framework: A decolonial approach to program evaluation

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract The Made in Africa Evaluation (MAE) framework is a decolonial approach to program evaluation developed by African evaluators over the past 14 years. MAE may be appropriate to community psychologists who practice program evaluation or conduct research in Africa, but little is known about its implementation.

Internet use and adolescent development: A conceptual model integrating behavioral and contextual theories

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract In the digital era, adolescent development is deeply embedded in the cyber environment. Despite ongoing debate on the benefits and/or risks that Internet use brings to adolescents in empirical studies, conceptual and theoretical discussion on the influences of the intensity and modalities of Internet use is peripheral.
