Available in PDF, EPUB and Kindle. Book excerpt: Weather during the growing season is critical for corn and soybean yields. Adjusting for weather in an analysis of historical U.S. corn and soybean yields is important for determining underlying trends and future yield expectations. Models for U.S. corn and soybean yields provide estimates of the effects of weather on yields for those crops, allowing an analysis of those effects to be used to derive weather-adjusted trend yields. The corn model also includes planting progress by the middle of May. The estimated models indicate that reductions in precipitation below its average result in larger declines in yields than the gains in yields resulting from increases in precipitation of equal magnitudes above its average. The yield models are used to track effects of high temperatures and drought on U.S. corn and soybean yields in 2012 and to provide estimates for expected 2013 yields. Further, the models provide a framework for assessing changes in expected yields due to planting progress and weather developments. Figures and tables. This is a print on demand report.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to investigate the relationship between weather, technology, and corn and soybean yields in the U.S. Corn Belt. Corn and soybean yields, monthly temperature, and monthly precipitation observations were collected over 1960 through 2006 for Illinois, Indiana, and Iowa. Multiple regression models were developed based on specifications found in studies by Thompson (1962, 1963, 1969, 1970, 1985, 1986, 1988). Estimated models explained at least 94% and 89% of the variation in corn and soybean yields for each state, respectively. This research provided strong evidence that precipitation, temperature, and a linear time trend to represent technological improvement explained all but a small portion of the variation in corn and soybean yields in the U.S. Corn Belt. An especially important finding was that relatively benign weather for the development of corn since the mid-1990s should not be discounted as an explanation for seemingly high yields. The potential impact of this finding on the agricultural sector is noteworthy. Trend yield forecasts based on perceptions of a rapid increase in technology may eventually lead to poor forecasts. Unfavorable weather in the future may lead to unexpectedly low corn yields that leave producers, market participants, and policy-makers wondering how such low yields could have occurred despite technological improvements.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States is one of the largest producers and exporters of corn and soybeans globally partly because of yields that are among the highest in the world. However, a changing climate could affect these yields, which could ultimately affect production and the availability of products for export. In this report, the authors estimate that U.S. corn yields could increase 3.1 percent and soybean yields could decrease 3.0 percent in 2036 relative to 2016, based on climate projections. These results are driven primarily by the increased frequency of periods of extreme heat and declines in precipitation in counties east of the 100th meridian part of the United States. These estimates are then used in a simulation model to explore the market implications from these yield projections, and those results indicate that these yield changes could affect U.S. production and ultimately trade. The estimated growth in U.S. corn yields increases corn production that could ultimately affect the amount of corn the United States has available to export. Holding yields in other countries fixed, the model indicates that U.S. corn exports increase 0.36 percent (the equivalent of $63 million). The decline in soybean yields decreases production, leading to a 1.17-percent drop in U.S. exports (the equivalent of $319 million) based on 2016 exports

Available in PDF, EPUB and Kindle. Book excerpt: This thesis explores how satellite data can be used to deepen our understanding of the corn and soybean production system in the US Midwest. One of the major characteristics of the Corn Belt is that corn and soybeans are grow in rotation, alternating crops from year to year. Rotation practices are however not very well captured by currently available data. On one side, official statistics provide a wide coverage, yet contain only information on average yield or total area, not on the share of fields under rotation. Likewise, data from experimental fields gives very precise information on potential benefits of rotation, yet are confined to a very small number of fields. Satellite data offers an interesting middle ground, providing data at the field level at a very large scale, over a long time horizon. The dataset I assemble for this study contains ten years of crop choice, yield, weather and prices data for close to two million fields in 9 states. Using this dataset, I make three main contributions. The main contribution addresses the question of aggregation of yield response to prices. Price increases typically lead to yield increases, yet also to an extension of cultivated area. If the new area is however of lower productivity, the price increase also leads to a larger number of fields having lower yield, which tends to reduce average yields. I show that this is the case, finding that an analysis at the county level underestimates the yield elasticity compared to an analysis at the field level, using satellite date. The second contribution from the dataset is to highlight several stylized facts that have received less attention in the literature. I document for example a positive correlation between a field's potential for corn and for soybean yields. This finding explains well the fact that many fields in my sample are found to be constantly in rotation. I show finally that there is a tendency to plant more often corn on fields with higher fertility, while low fertility soils tend to be planted to soybeans. The third contribution of my thesis is to suggest new methods to estimate the rotation effect. I discuss how neglecting the fact that better fields are more often planted to corn can lead to a strong underestimation of the rotation effect. This call for different types of estimators, based on plot fixed-effects exploiting within-plot variation. The standard difference-in-difference method can however not be applied in the case of rotation, and I discuss how to adapt this strategy to the rotation case.

Available in PDF, EPUB and Kindle. Book excerpt: We investigate the effect of crop price and climate variables on rainfed corn and soybean yields and acreage in the United States using a large panel dataset for the 1977-2007 period. Instrumental variables are used to control for endogeneity of prices in yield and acreage regressions, while allowing for spatially auto-correlated errors. We find that an increase in corn price has a statistically significant positive impact on corn yield, but the effect of soybean price on soybean yields is not statistically significant. The estimated price elasticities of corn yield and acreage are 0.23 and 0.45, respectively. Of the increase in corn supply caused by an increase in corn price, we find that 33.8% is due to price-induced yield enhancement and 66.2% is due to price-induced acreage expansion. We also find that the impact of climate change on corn production ranges from -7% to -41% and on soybean ranges from -8% to -45%, depending on the climate change scenarios, time horizon, and global climate models used to predict climate change. We show that the aggregate net impact of omitting price variables is an overestimation of the effect of climate change on corn yield by up to 9% and on soybean yield by up to 15%.
