Abstract Declining survey response rates have driven many researchers to seek out cost‐effective methods of increasing participation, such as conducting surveys online, paying incentives, and using social media engage hard‐to‐reach populations. Malicious actors can exploit the monetary incentives anonymity online surveys, threatening integrity data. We share two recent experiences that were inundated with fraudulent responses. Our objective is increase awareness this emerging issue offer...
Abstract Over the last two decades, number of honey bee colonies performing pollination services for California almond industry has grown steadily and now equals a substantial share all in United States. Most US beekeeping operations have not expanded their colony numbers at current levels fees. Thus, as acreage increased, marginal supplier moved further away from California, increasing interstate shipments. We provide conceptual representation supply demand U.S. pollination, utilize...
Abstract Through a framed field experiment with livestock farmers in the Northeast and Southeast United States, this research explores whether an informational nudge changes producers' selection of two‐month intervals and/or increases likelihood enrollment pasture, rangeland, forage (PRF) insurance. We find no evidence that influences interval choices; however, producers are more likely to enroll when PRF is as risk management decision regarding loss. Risk aversion, familiarity other States...
California almond orchards are most U.S. beekeepers' first stop on their pollination and honey production circuit, so the agrochemicals bees exposed to in almonds can shape vitality of colony for rest year. We explored potential bee exposure bee-toxic during bloom by utilizing Department Pesticide Regulations' Use Report database from 1990 2016. found that overall, growers observing pesticide labels reducing use labeled pesticides bloom. However, we also insect growth regulators, fungicides...
Abstract Using a novel policyholder-level data set, we analyse participants’ choices of 2-month index intervals in the Rainfall Index for Pasture, Rangeland and Forage (RI-PRF) insurance programme. We first provide conceptual model that illustrates participation patterns rainfall insurance. then connect these predicted to some empirical evidence from which is subset provided by USDA Risk Management Agency all RI-PRF participants Nebraska Kansas during years 2013–2017. Because correlations...
Abstract In California, the most significant insect pest of almonds and pistachios is navel orangeworm, Amyelois transitella (Walker) a walnuts. This attacks nuts infestation associated with aflatoxin contamination. While there are multiple integrated management (IPM) practices available, anecdotal evidence suggests that not all tools equally utilized. To understand current industry barriers to adoption, authors surveyed tree nut growers professionals across 7 University California...
Abstract Government‐supported farm programs can provide operators with different economic incentives regarding the use of their land. We study two US relevant to hay and pastureland, Conservation Reserve Program (CRP) Pasture, Rangeland, Forage (PRF) Index Insurance. Using county‐level enrollment availability data, we find that introduction PRF reduces in CRP. This interaction potentially returns environmentally sensitive farmland back into production. also document heterogeneity effects...
Managed honey bee colonies provide pollination services, which are an essential input in the production of many crops United States. Over last decade, supply U.S. has become volatile as a result multiple factors inhibiting colony health. This paper investigates impact that uncertainty on California almond market, largest user managed pollinators world. I develop theoretical model and show growers can reduce moral hazard agreements by paying beekeepers according to delivered strength. utilize...
Most Japanese plum cultivars are self-infertile. In commercial orchards, cross-compatible pollinisers have to be interplanted ensure fruit set. The self-incompatibility is controlled by S-loci in the pistil and pollen, which tightly linked each other. Prunus S-RNase-specific PCR primers Pru-C2 PCE-R were used study candidate compatible for cultivar 'Queen Garnet', known its high nutritional value. A total of 13 genotypes, including three other nine DAFF breeding lines, tested. possesses gh...
Abstract Replacement brood cows are among the most significant investments for cow‐calf operations, thus crucial to profitability. Many producers find it cost effective purchase replacements from a reliable replacement heifer seller, though by doing so they increase risk of reproductive inefficiency due unknown characteristics heifers. When important information about product is missing buyers, seller can build reputation over time that acts as signal quality. Previous work has explored...
The world’s dependence on managed pollinators is growing due to decreasing native bee populations, coupled with increased production of crops requiring pollination services. Growers pollinated may have opportunities enhance contracts attract beekeepers and promote health. must assess these benefits relative implementation costs, yet little information exists. We investigate the value contract enhancements commercial participating in California almond services, a event that demands roughly...
Over the last two decades, quantity of honey bee colonies required to perform pollination services for California almond industry has grown steadily and now equals a substantial share U.S. population colonies. Most beekeeping operations have not been willing expand colony capacity without signif- icant increases in fees. Thus, as acreage increased, marginal supplier likely moved further away from California, increasing interstate shipments. To explore this concept, we analyze temporal...
