Analyzing Large Workers’ Compensation Claims Using Generalized Linear Models And Monte Carlo Simulation, Fatemeh Davoudi Kakhki, Steven A. Freeman, Gretchen A. Mosher Dec 2018

Analyzing Large Workers’ Compensation Claims Using Generalized Linear Models And Monte Carlo Simulation, Fatemeh Davoudi Kakhki, Steven A. Freeman, Gretchen A. Mosher

Agricultural and Biosystems Engineering Publications

Insurance practitioners rely on statistical models to predict future claims in order to provide financial protection. Proper predictive statistical modeling is more challenging when analyzing claims with lower frequency, but high costs. The paper investigated the use of predictive generalized linear models (GLMs) to address this challenge. Workers’ compensation claims with costs equal to or more than US$100,000 were analyzed in agribusiness industries in the Midwest of the USA from 2008 to 2016. Predictive GLMs were built with gamma, Weibull, and lognormal distributions using the lasso penalization method. Monte Carlo simulation models were developed to check the performance ...

Fiscal Reform Scenarios And Accessibility 2018.08.20.Docx, Guillermo Fernandez Nov 2018

Fiscal Reform Scenarios And Accessibility 2018.08.20.Docx, Guillermo Fernandez

Guillermo Fernandez

Since signing the peace accords in 1996, the Guatemalan government committed to increase the tax burden of 1995 by 50% to a total of 13%. This target has only been reached 4 times in more than two decades. There have been multiple attempts at tax reforms that have failed or been incomplete. Guatemala exhibits much income inequality and is one of the poorest countries in the region.  
Given this background, the problem to be considered in this analysis is that there is little information regarding how different tax reforms would affect the accessibility to food in Guatemala. With information regarding ...


Profitability Of Developing Beef Heifers On Stockpiled Winter Forages, Zachary David Mcfarlane, Chris Boyer, J. Travis Mulliniks Nov 2018

Profitability Of Developing Beef Heifers On Stockpiled Winter Forages, Zachary David Mcfarlane, Chris Boyer, J. Travis Mulliniks

Journal of Applied Farm Economics

We estimate the profitability of developing heifers on one stockpiled cool-season grass and two stockpiled warm-season grasses during the winter months by comparing distributions of net present value (NPV) over an 11-year useful life. Furthermore, distributions of payback period and the break-even price for each calf over the heifer’s production life were generated for each forage species. These results are compared across forages as well as to a simulated drylot system for heifer development. Data comes from a grazing experiment in Tennessee, where heifers grazed big bluestem and Indian grass combination (BBIG), switchgrass (SW), or endophyte-infected tall fescue (TF ...

Utilizing Municipal Compost And Equine Stall Waste As Potential Economic Alternatives In An In-Ground Pot-In-Pot Production System, Ashley Robert, Alyx Shultz Nov 2018

Utilizing Municipal Compost And Equine Stall Waste As Potential Economic Alternatives In An In-Ground Pot-In-Pot Production System, Ashley Robert, Alyx Shultz

Posters-at-the-Capitol

For Western Kentucky farmers, one viable income source could be a pot-in-pot nursery production. One of the highest costs of production in this system was the planting media that the plants were grown in. Economical alternatives to high-priced, non-renewable peat-based mixes were important to consider. Unique to this region, were two renewable soil amendments that may help farmers to widen their profit margin in a pot-in-pot system. This research looked at the economic viability of locally sourced horse stall waste and municipal compost as soil amendments to a traditional bark and peat based mix. Initial cost projections were favorable for ...

Initiative 427: Nebraska Medicaid Expansion, J. David Aiken Oct 2018

Initiative 427: Nebraska Medicaid Expansion, J. David Aiken

Cornhusker Economics

This article summarizes information regarding Initiative 427–the Medicaid expansion question on the November 6, 2018 ballot. It reprints the actual ballot language and the Nebraska Secretary of State’s summary of arguments for and against Initiative 427.

Background. Originally Medicaid covered the elderly, the disabled, children in low-income families, and low-income pregnant women. In 2010 Medicaid coverage was expanded by Congress to include the working poor. In 2012 the U.S. Supreme Court ruled that the provision of the Affordable Care Act (ACA) requiring states to expand Medicaid was unconstitutional. This made it a state option whether or not ...


Farm Programs, Payments And Prospects Oct 2018

Farm Programs, Payments And Prospects

Cornhusker Economics

The USDA Farm Service Agency (FSA) began issuing payments to producers in October for Price Loss Coverage (PLC) and Agriculture Risk Coverage (ARC) programs for the 2017 crop year. While these farm program payments had provided substantial cash flow to help buffer falling market price and farm income projections in the past three years, the current programs will provide relatively little cash flow for now and for the coming year. Only the ad hoc trade assistance payments and the outlook for new farm programs and decisions in 2019 may provide potential relief from the current outlook.

Farm Location Influence On The Optimal Crop Insurance And Pre-Harvest Hedging Level, Cory Walters Sep 2018

Farm Location Influence On The Optimal Crop Insurance And Pre-Harvest Hedging Level, Cory Walters

Cornhusker Economics

Improving farm financial health can come from improving the understanding of the market forces influencing the optimal crop insurance contract and preharvest hedging risk management tools. The biggest challenge for farmers is the difficulty of assessing risk since experiencing risk, is by default, rare. Additionally, farmers receive advice about which crop insurance plan they should purchase or how much pre-harvest hedging they should do from sources, such as farm magazines, that likely do not consider the differences in individual risk exposure. Following the advice of such sources could result in producers being inadvertently exposed to more risk. A producer’s ...

The Corn/Soybean Rotation And Profitability, Matt Stockton, Devin Broadhead Sep 2018

The Corn/Soybean Rotation And Profitability, Matt Stockton, Devin Broadhead

Cornhusker Economics

One of the most basic questions farmers must answer on an annual basis is what to plant. In some cases this is simply a choice among cultivars in others it is a choice among different crop types. In Nebraska the choice may vary considerably since many different crop types are grown. This discussion focuses on the factors that affect profitability, which are created by both biology and economics, and how that might be used to make the best crop rotation selection between corn and soybean cropping systems.


Importance Of Being Digital Ready – What Does That Mean?, Charlotte Narjes Sep 2018

Importance Of Being Digital Ready – What Does That Mean?, Charlotte Narjes

Cornhusker Economics

Communities often determine if they are digital ready on whether or not high speed internet is available. The conversation then focuses on who has high speed internet and who does not. Hence, the divide. High speed internet is an important factor on whether or not a community can be competitive in a global market. But, it is not the only digital-ready factor necessary to compete in a global economy. One challenge of focusing on the divide is that assumptions are made that individuals do not have skills in rural areas to use technology and, that these rural residents may not ...

A Model For Farmer Support In Zimbabwe – Opportunity For Change, Brierly Kuhudzayi, Daniela Mettos Aug 2018

A Model For Farmer Support In Zimbabwe – Opportunity For Change, Brierly Kuhudzayi, Daniela Mettos

Cornhusker Economics

Community development refers to the collective action of a group of people to improve their quality of life or to fix a problem they face. It involves active participation by the people facing the problem. Input subsidy programs (ISPs) are commonly used in Sub-Saharan Africa as a strategy to achieve several development goals. They generally aim to improve the lives of poor subsistence-level farmers, improve agricultural output, and stimulate the economy. However, ISPs are not technically a community development tool because they are typically centrally planned and top-down in nature.

Price Seasonality In The Catfish Value Chain In Uganda, James O. Bukenya Aug 2018

Price Seasonality In The Catfish Value Chain In Uganda, James O. Bukenya

Professional Agricultural Workers Journal

Seasonal patterns in production and demand are common in many agricultural markets. Charting these patterns provides information that complements fundamental and technical analyses. It is in this spirit that this paper seeks to examine price seasonality in the catfish value chain in Uganda. The analysis draws on monthly prices taken from secondary source recorded data and uses moving average index to chart price patterns. The results reveal distinct seasonal patterns in the farm-gate, ex-vessel, retail, and wholesale market channels. Across market channels, the results for farm-gate versus ex-vessel prices reveal that farm-gate prices are more affected by seasonal effects compared ...
