The extensive adoption of genetically engineered (GE) varieties in U.S. agriculture has dramatically changed the patterns of pesticide use. How this process ultimately affects environmental risk remains an open question. Previous studies have typically relied on aggregate trends to infer the...

What explains the surge and plunge commodity markets have undergone in the past 20 years Are speculators to be blamed Do prices reflect full information These are the main questions addressed in this paper, in the context of the corn market. This paper formulates and calibrates two quantitative...

The magnitude and sign of risk premiums provide relevant information on the structure of a given market. However, there is no consensus on commodity markets if there is a risk premium, and if so, if it is positive or negative. In addition, in recent years, there has been a discussion on the...

For grain and oilseed futures, deliveries facilitate convergence by allowing for arbitrage between the physical commodity and the “paper” (i.e., futures) markets. A sizeable literature has looked at deliveries to answer questions about price convergence and about the value of options...

The objective of this research paper is to study an overtime analysis of time series data to measure compound growth and predict future area, production and yield of Punjab province and entire Pakistan. In this research, data retrieved from government reports for the period of 1981-2019 is...

Benefiting from pedoclimatic conditions favorable to grain cultivation, Romania was an important player in international trades. In the context of the current geopolitical changes, the paper aims to identify the position occupied by Romania in the global trade of maize and wheat in the period...

Conservation tillage has been widely recommended for implementation in the U.S. for its environmental benefits. The effect of conservation tillage on crop yield is a subject of continued concern amongst farmers who have not adopted the practice. Previous empirical research on the yield...

The COVID-19 pandemic induced numerous supply chain shocks in U.S. agricultural markets though few empirical studies have sought to disentangle commodity price impacts caused by unique changes in food and non-food agricultural product demand. Using a data-modified version of the...

This study explains the effects of crude oil prices on copper and maize prices. Vector autoregressive and vector error correction models are used to study the relationship between oil prices and prices of copper and maize. The commodity price data used consist of average monthly prices of each...

This paper aims to analyze the decision regarding corn storage (for the first and second crops) in the current context of the Brazilian market through an economic model of dynamic storage. We consider storage as a competitive economic activity and that agents can maximize profit through rational...

We estimate the cost of transporting corn and the resulting degree of spatial differentiation among downstream firms that buy corn from upstream farmers and examine whether such differentiation softens competition enabling buyers to exert market power (defined as the ability to pay a price for...

In this article, we demonstrated the dynamic impact of a bumper harvest and drought shocks on the maize market and on the trade regime in Ethiopia. Regional market integration of Ethiopia's white maize market with the South Sudan and Kenyan maize markets was also examined using cointegration...

We estimate the cost of transporting corn and the resulting degree of spatial differentiation among downstream firms that buy corn from upstream farmers and examine whether such differentiation softens competition enabling buyers to exert market power (defined as the ability to pay a price for...

Ethiopian economy has grown at an average rate that surpasses that of almost any other economy in the region over the last two decades. At the center of this development is the high priority placed on accelerating agricultural growth and achieving food security and poverty alleviation. Over the...

Integrated nutrient management (INM) is a management strategy that aims at maintaining or adjusting of soil fertility and plant nutrient supply to an optimum level for sustaining the desired crop productivity through all possible sources of plant nutrients in an integrated manner through a...

Optimal crop choice and fertilizer applications depend on the stochastic dynamics of commodity prices, fertilizer prices, and the agronomic effects of rotation versus monoculture. The efficient decision rule accounts for real option values associated with maintaining land disposition in an...

Conventional threshold models of price transmission allow for different speeds of adjustment to equilibria depending on the magnitude of price differentials between markets. However, these models typically assume only one underlying long‐run equilibrium price relationship. In this article we...

In this study we analyze recent and proposed maize marketing reforms in Zambia. To capture the effects of changing transport systems, we use a continuous‐space model in place of the traditional point‐representation model of Takayama and Judge. This method permits us to use prereform data on...

Changes in maize price levels and variability in Ghana are investigated. A model of wholesale price determination is reviewed in which grain stocks are held for speculative storage as well as export to neighboring countries in the Sahel. To test the model, an Autoregressive Conditionally...

This study compared costs and returns between stacked Bt/Ht GM and non-GM maize and identified determinants of GM maize adoption in Southern Vietnam. Data were from the 2016 Summer-Autumn cropping season, one year after GM maize was commercialised in Vietnam. The main economic benefits of GM...

The purpose of this paper is to evaluate the degree of dicotyledonous weed species of maize culture, the effectiveness of weed control products and the evaluation of maize yield. Experimental factors A-treatment variants: a1-pre-emergence herbicide with Tender 1.5 l/ha + Merlin Flex 0.4 l/ha...

Industry structure and social capital could affect traders, market performance and distribution of economic resources such as food. This study assesses the effect of industry structure and social capital on traders’ profitability and resilience. We use Bayes Model Averaging regression...
