Vertical Price Transmission in Food Markets: New Evidence From Meta‐Analysis
Agribusiness, EarlyView.ABSTRACT A growing body of empirical research has examined price dynamics along the food supply chain, yet findings remain heterogeneous and often conflicting. This study conducts a meta‐analysis of 140 studies, totaling 652 observations, to examine (1) the reported presence of asymmetric price transmission and (2) the reported direction of price ...

Agribusiness, EarlyView.ABSTRACT This paper examines how mandatory disclosure of added sugar content on the updated U.S. Nutrition Facts Panel (NFP) affects consumer demand and market outcomes. Using NielsenIQ Retail Scanner Data (2015–2020) and a random coefficient discrete choice model, we estimate how added sugar labeling influences purchasing behavior in yogurt and cookie

Weather Attention in Online Discourse and Price Uncertainty in Agricultural Futures Markets
Agribusiness, EarlyView.ABSTRACT Weather is a central determinant of production risk in agricultural markets, but markets respond not only to weather conditions themselves, but also to how those conditions are noticed, framed, and interpreted in public discourse. In this setting, real‐time online weather discussions may shape price uncertainty by influencing how market ...

Agribusiness, EarlyView.ABSTRACT The derived demand for the increased demand for meat and dairy products is clearly observed in the fast‐paced growth of the Indian feed industry and its increased demand for agricultural commodities (e.g., corn, soybean, rice, wheat, broken rice, millet, etc.) as feed ingredients.

Food Security Strategy, Macroeconomic Dynamics and Food Import Sensitivity in Qatar
Agribusiness, EarlyView.ABSTRACT Qatar has limited agricultural land and water resources and therefore remains highly dependent on food imports. This structural dependency makes Qatar vulnerable to external shocks such as the recent Gulf crisis, threatening food security and disrupting global supply chains. In response to previous shocks, Qatar started implementing a National

Drought Exposure and Dynamic Input Adjustment in North Central U.S. Agriculture
Agribusiness, EarlyView.ABSTRACT This article examines whether realized extreme drought episodes affect the speed of adjustment of derived input demands and output supplies toward their long‐run equilibrium in U.S. agriculture, focusing on states in the North Central Region.

Current Opinion in Nephrology and Hypertension, 1996
The pathogenesis of chronic rejection is a complex network of immunological, metabolic and haemodynamic events leading to a cascade of cellular and molecular events with a subsequent remodelling of the graft. Evidence suggests that the frequency and intensity of acute rejection episodes strongly correlate with graft loss as a result of chronic ...

Current Opinion in Immunology, 1994
Although chronic rejection remains the most crucial cause of organ graft loss over the long term, its etiology is not well defined. Early injury to graft endothelial cells caused by alloantigen-independent factors, such as ischemia or reperfusion, as well as alloantigen-dependent events, such as acute rejection, have been implicated.

Seminars in Nephrology, 2001
The major histocompatibility complex molecules are the primary antigens responsible for causing graft rejection, and T-cell recognition of alloantigens is the cardinal event initiating cellular rejection. Current concepts suggest that direct allorecognition mediates acute rejection, whereas indirect allorecognition mediates chronic rejection. In biopsy

The Pathophysiology of Chronic Rejection
The American Journal of the Medical Sciences, 1997The understanding of chronic rejection has been greatly enhanced by the use of genetically controlled experimental models using inbred rats. Models that express all lesions encountered in human transplants are described. Findings of chronic rejection depend on genetic disparity, strength of the immunologic reaction, response to injury, and perpetuation
