Food Tastes in the United States: Convergence or Divergence?

open access: yesAgribusiness, EarlyView.
ABSTRACT This study investigates how food consumption tastes have changed in recent decades across the United States. Using NielsenIQ data for over 77 million transactions, there is evidence of divergence in food tastes across regions from 2007 to 2016 and across households of different income, education, and race/ethnicity groups.

A structure from motion inequality

open access: yes, 2007
We state an elementary inequality for the structure from motion problem for m cameras and n points. This structure from motion inequality relates space dimension, camera parameter dimension, the number of cameras and number points and global symmetry ...

The Power of Unity: Collective Action and Smallholder Agricultural Performance in West Africa

open access: yesAgribusiness, EarlyView.
ABSTRACT We analyze the impact of collective action through farmer‐based organizations (FBOs) on smallholders' farm performance and income inequality in Ghana, Benin, The Gambia, and Mali. We find that FBO membership increases cereal yield in Ghana and The Gambia, legume yield in Mali, ruminant numbers in Benin and The Gambia, and total farm income in ...

A Linear Generalization of Gronwall's Inequality [PDF]

open access: yesProceedings of the American Mathematical Society, 1965
where k(t, s) and w0(t) are known non-negative functions and u(t) is an unknown non-negative function. For examples, one can refer to Bellman [l, pp. 35 ff.], Coddington and Levinson [2, pp. 37 ff.], Willett [3], and others. In order to obtain from (1.1) a genuine upper bound for u(t), i.e., an upper bound independent of u, it seems necessary to ...

The Role of Certifications in Improving Household Food Security Among Peruvian Farmers

open access: yesAgribusiness, EarlyView.
ABSTRACT Achieving global food security requires sustainable transformations in agri‐food systems. Voluntary Sustainability Standards (VSS) such as Organic and Fairtrade aim to internalize certain social and environmental costs while promoting more equitable value distribution, improved market access, and sustainable production practices.

Robust Model Predictive Control of Networked Control Systems under Input Constraints and Packet Dropouts

open access: yesAbstract and Applied Analysis, 2014
This paper deals with the problem of robust model predictive control (RMPC) for a class of linear time-varying systems with constraints and data losses. We take the polytopic uncertainties into account to describe the uncertain systems.

The role of the wealth distribution on output volatility [PDF]

open access: yes
We explore the link between wealth inequality and business cycle fluctuations in a two-sector neoclassical growth model with endogenous labor and heterogeneous agents. Assuming that wealth inequality is described by the distribution of shares of capital,
