In corporate finance, the impact of capital structure on firm performance has been widely studied. This article extends study to situation in agriculture, explicitly addressing difference between family farms and firms. We use Malmquist productivity growth index as a proxy for (debt) farm performance. compare results with those from traditional model that uses profitability (e.g., return equity (ROE)) measure. Using data Dutch arable farms, show debt no effect ROE, whereas it positive growth.
Abstract Fertilizer use remains very low in most of Africa despite widespread agreement that much higher rates are required for sustained agricultural productivity growth. This study uses longitudinal farm survey data to estimate maize yield response functions a relatively high‐potential zone Zambia determine the profitability fertilizer under range small‐farm conditions found within this zone. The theoretical framework used incorporates agronomic principles crop growth process. We...
Abstract Using a volatility spillover model, we find evidence of significant spillovers from crude oil prices to corn cash and futures prices, that these effects are time‐varying. Results reveal markets have become much more connected after the introduction Energy Policy Act 2005. Furthermore, when ethanol–gasoline consumption ratio exceeds critical level, transmit positive into movements in energy‐driven. Based on this strong link between new cross‐hedging strategy for managing price risk...
Citrus huanglongbing (HLB), or greening, is the most destructive citrus disease worldwide and threatening sustainability of industry in major citrus-growing regions. Various treatments have been proposed literature to manage disease. We review such conduct an economic analysis based on reported treatment effects fruit yield quality identify cost-effective management strategies. Our results suggest that, among we reviewed, broad-spectrum insecticides provide only strategy for mitigating...
The fruit and vegetable industry is an important segment of the U.S. agriculture. 2017 Agriculture Census shows that had total sales USD 48 billion from over 10 million acres land. However, last two decades, production major crops in United States has been declining while imports have grown significantly. rapidly growing posed challenges to sustainability domestic industry. This study provides a systematic review fresh trade between Mexico, by far largest source imports, highlighting...
Abstract We introduce the concept “excess capital capacity” and employ a stochastic input requirement frontier to measure excess capacity in agricultural production. also propose two‐step estimation method that allows endogenous regressors models. The first step uses generalized of moments get consistent estimates parameters presence regressors. second maximum likelihood evaluate factors influence it. empirical application Dutch cash crop farms found varying degrees capacity. policy...
Tomatoes are one of the world's most consumed vegetable crops. In United States, domestic production meets about 40% total demand for fresh-market tomatoes, with rest met by imports, mostly from Mexico and Canada. Since 2000, however, fresh tomato in States has exhibited a steady declining trend. One major reason is increased competition Mexico. This 4-page fact sheet written Zhengfei guan, Trina Biswas, Feng Wu published UF/IFAS Food Resource Economics Department argues US government...
This article presents a general conceptual framework for integrating agronomic principles into economic production analysis. We categorize inputs in crop growth and facilitating inputs. Based on this dichotomy we specify an asymmetric function. The robustness of the is tested using crop‐level panel data potato Netherlands. test results do not reject proposed framework, specification better represents underlying technology.
Huanglongbing (HLB) is a devastating citrus disease worldwide. A three-pronged approach to controlling HLB has been suggested, namely, removal of HLB-symptomatic trees, psyllid control, and replacement with HLB-free trees. However, such strategy did not lead successful control in many citrus-producing regions, as Florida. We hypothesize that this because the small-scale or incomprehensive implementation program; conversely, comprehensive at regional level can successfully HLB. To test our...
ABSTRACT The U.S. produce industry has been facing significant challenges due to rising minimum wages. This study proposes a modeling framework analyze the impacts of wages and assess their effects on sector, focusing strawberry industry, which confronts both escalating labor costs competition from low‐cost imports. A structural model with nested Synthetic Inverse Demand System (SIDS) is employed how wage increases affect in short long terms. Our findings reveal that will lead substantial...
This paper models the U.S. strawberry market and examines how increasing imports from Mexico affect prices shipment values of California Florida winter strawberries. The Synthetic Inverse Demand System is used to quantify impact Mexican shipments on estimation results indicate that are responsive supply each three sources, suggesting an integrated, competitive national market. simulation suggest rapidly growing will cause large losses industry, posing challenges sustainability survival...
CONTEXTAccording to the FAO, crop diseases cause about $220 billion in losses each year, and development of disease-resistant cultivars is one potential long-term solution combat such losses. However, limited research has considered cultivar adoption context perennial cropping systems, where not replanted at end season.OBJECTIVEWe use citrus greening disease as a case study demonstrate how nature could affect timing resistant cultivars, further identify threshold resistance efficacy which...
The economic performance of pest management practices is a critical factor when farmers make adoption decisions. Partial budget analysis widely used tool to evaluate the financial effects different in agricultural production. It provides an rationale for selecting optimal treatment by evaluating cost-effectiveness treatment. This publication explains how employ partial using real-world example. step-by-step guide examining costs and benefits two approaches, fumigation nematicides, manage...

Abstract We identify farms’ optimal investment path in capital assets and compare it with their actual to assess the direction extent of deviation from investment. A probit model is further used investigate determinants probability that a farmer over‐ or under‐invests assets. use panel dataset Dutch dairy farms over period 2003–2013, find most under‐invest during study period. Although number had over‐invested relatively small, these account for biggest share total The results show...
The US produce industry faces intensifying competition from imports, particularly those Mexico, the largest exporter of to United States. Fresh imports Mexico have grown dramatically in recent years. This study examines impact increasing fresh tomato on market price and revenue growers. Results show that prices are highly sensitive supply, suggesting a saturated market. Imports significant negative impacts domestic tomatoes. A scenario 50% increase could result $252 million (27%) loss for...
Purpose – The purpose of this paper is to provide a unified theoretical framework that explains farm capital structure choice. Design/methodology/approach accommodates different credit access scenarios and heterogeneous risk profiles borrowers. It recognizes the costs are endogenously determined, reflecting degree accessibility markets. Based on proposed model comparative statics derived thereof, empirically tests impacts factors Findings framework, choice using statics. Results suggest...
Abstract Using data collected from a pork firm survey, we develop modeling framework and use the conjectural variation method to examine effect of market power on food safety industry in China. Probit models with two‐step Heckman selection procedure are applied identify determinants likelihood degree violations. Market is found reduce violation but not violation. Other factors such as traceability systems, adoption risk control systems standards, scale scope operations also impact Findings...
