International Dimension of Agricultural Prices [PDF]

Journal of Agricultural and Applied Economics, 1974
Events of the past two years, specifically the agricultural price explosion of 1973, have strongly emphasized the growing interdependency of countries in the production, consumption and trade in agricultural products. The illusion of a closed agricultural economy has been dealt a series of severe blows.

Testing for asymmetric cointegration of Italian agricultural commodities prices: Evidence from the futures-spot market relationship

Agricultural Economics (AGRICECON), 2022
The volatility of food prices still raises concerns among agricultural market players, increasing interest in the futures markets, thus calling for a better understanding of the connection between the futures and the Italian spot prices.

Modeling long-run global agricultural price dynamics: a trend-cycle decomposition and unobserved components approach

Frontiers in Sustainable Food Systems
IntroductionSince the 1960s, global agricultural prices have exhibited significant episodic volatility. This study aims to conduct a trend-cycle decomposition of these prices to identify the cyclical patterns of their long-run dynamic evolution ...

Expliquer les évolutions des cours des matières premières agricoles : À l’impossible, nul n’est tenu !

Oléagineux, Corps gras, Lipides, 2008
How to explain the recent developments in the prices of agricultural raw materials? This article tries to trace the chronology of events and identify the mechanisms by which factors of change in agricultural prices act. From this analysis of temporal and

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Do agricultural commodity prices asymmetrically affect the performance of value-added agriculture? Evidence from Pakistan using a NARDL model

Humanities & Social Sciences Communications, 2023
In the last few decades, rising prices of agricultural commodities have been an area of concern for most countries owing to high population growth, increased unemployment, and per capita food needs.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

FEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...
