Applied Economic Perspectives and Policy, EarlyView.ABSTRACT In recent decades, agriculture has become increasingly concentrated through horizontal mergers and acquisitions via corporate entities, and policy makers are concerned this will be exacerbated by the aging population of farm operators. To reduce market concentration in agriculture, many states have enacted policies to entice new prospective ...

Asymptotic behaviour for Schrodinger equations with a quadratic nonlinearity in one-space dimension
Electronic Journal of Differential Equations, 2001 We consider the Cauchy problem for the Schr"{o}dinger equation with a quadratic nonlinearity in one space dimension $$ iu_{t}+frac{1}{2}u_{xx}=t^{-alpha}| u_x| ^2,quad u(0,x) = u_0(x), $$ where $alpha in (0,1)$.

Fujita-type theorems for a class of coupled semilinear parabolic systems with gradient terms
Advances in Difference Equations, 2018 This paper concerns the asymptotic behavior of the solution to a class of coupled semilinear parabolic systems with gradient terms. The Fujita-type blow-up theorems are established and the critical Fujita curve is determined not only by the behavior of ...

Consumer Preferences for Craft Beer: The Interplay of Localness and Advertising Language
Agribusiness, EarlyView.ABSTRACT This study explores the influence of the language of the label, origin of production, and origin of brewing ingredients on Croatian consumers' preferences and willingness to pay for organic craft beer. Employing an online survey and a choice experiment among 223 Croatian alcohol consumers, we find that while there's a willingness to pay a ...

Band asymptotics in two dimensions
Advances in Mathematics, 1981 Let X be a rank one symmetric space (e.g., S”, RP”, CP”,...) and let A be its Laplace-Beltrami operator. It is known that the spectrum of A is discrete and consists of a sequence of eigenvalues a, = k(k + a), k = 0, 1, 2 ,a.., (1.1) each occurring with multiplicity N, = (b/(n l)!) k”-’ + O(k”-*), (1.2) n being the dimension of X and a and b being ...

Agribusiness, EarlyView.ABSTRACT This study examines food price inflation rate convergence among EU27 Member States from 2005 to 2024, focusing on structural breaks, external shocks, and regional disparities. Using panel unit root tests and club convergence analysis, the findings reveal no overall convergence but identify multiple convergence clubs.

Agribusiness, EarlyView.ABSTRACT Food systems have a significant impact on environmental sustainability, underscoring the need for innovative technologies to support more sustainable agricultural methods. However, the adoption of these technologies hinges on consumer acceptance, making the analysis of consumer perceptions essential.
