An Elementary Humanomics Approach To Boundedly Rational Quadratic Models, Michael J. Campbell, Vernon L. Smith

ESI Working Papers

We take a refreshing new look at boundedly rational quadratic models in economics using some elementary modeling of the principles put forward in the book Humanomics by Vernon L. Smith and Bart J. Wilson. A simple model is introduced built on the fundamental Humanomics principles of gratitude/resentment felt and the corresponding action responses of reward /punishment in the form of higher/lower payoff transfers. There are two timescales: one for strictly self-interested action, as in economic equilibrium, and another governed by feelings of gratitude/resentment. One of three timescale scenarios is investigated: one where gratitude /resentment changes much more slowly than economic …

Introduction To The Special Issue On The Economics Of Religion, Jared Rubin

Economics Faculty Articles and Research

"The economics and political science of religion have blossomed into full-fledged fields in the last decade and a half. What was once a field on the far outskirts of economics and political science now regularly publishes in its top journals (see Figure 1).¹ By 1998, the field was large enough for Iannaccone (1998) to write a survey of the shape of the field. The field was very much at its infancy at that time, and most of the best work was done by sociologists and/or published in sociology journals. This has changed significantly in the 22 years since Iannaccone's …

Intertemporal Choice Experiments And Large-Stakes Behavior, Diego Aycinena, Szabolcs Blazsek, Lucas Rentschler, Charles Sprenger

ESI Working Papers

Intertemporal choice experiments are increasingly implemented to make inference about discounting and marginal utility, yet little is known about the predictive power of resulting measures. This project links standard experimental choices to a decision on the desire to smooth a large-stakes payment | around 10% of annual income | through time. In a sample of around 400 Guatemalan Conditional Cash Transfer recipients, we find that preferences over large-stakes payment plans are closely predicted by experimental measures of patience and diminishing marginal utility. These represent the first findings in the literature on the predictive content of such experimentally elicited measures of …

Uncertainties Abound In Nebraska Livestock Market Forecasts, Elliott James Dennis

Extension Farm and Ranch Management News

About one of the only things certain about forecasts this year has been the great deal of uncertainty. Numerous “novel” situations have confronted the industry making it difficult to estimate price magnitudes rather than just price direction. Clustered plant closures, government quarantine restrictions, and increasing at home phone consumption are just a few of the major issues the beef industry has had to tackle in the last six to eight months. Some things have returned to “normal” such as packing plant capacity and food service demand. Others are still in ongoing recovery.

Who knows what “normal” or “standard operating procedure” …

Technology Transfer In Spatial Competition When Licensees Are Asymmetric, Sougata Poddar, Swapnendu Banerjee, Monalisa Ghosh

Economics Faculty Articles and Research

We study technology transfer in a spatial competition with two asymmetric licensees (firms) with an outside innovator who decides how many licenses to offer and the optimal licensing contract. We show the optimal licensing policy is pure royalty contract to both licensees leading to a complete diffusion of the new technology. The result holds irrespective of the cost differentials between the licensees and for innovation of all sizes, that is, drastic or non‐drastic. This robust finding although supports the dominance of royalty licensing in practice; however, consumers may not be necessarily better off. We also throw light on the situation …

Comparing Profitability And Management Factors Across Operation Type: Independent Vs. Contract Growing, Elliott James Dennis

Extension Farm and Ranch Management News

First paragraph:

There is strong local and national interest in adding hog barns to existing row crop operations. Declining on farm income over the past several years has accelerated this interest. Grain operations cite diversifying farm income, adding another family to the farm operation, and/or replacing commercial fertilizer expense as the primary reasons for adding a hog barn.

Financial Health Of Grain Operations After Adding A Hog Barn, Elliott James Dennis

Extension Farm and Ranch Management News

There is strong local and national interest in adding hog barns to existing row crop operations. Declining on farm income over the past several years has accelerated this interest. Grain operations cite diversifying farm income, adding another family to the farm operation, and/or replace commercial fertilizer expense as the primary reasons for adding a hog barn.

While there is industry demand to increase hog contract growing, these agreements can possess significant benefits and risks to producers. This is the second of a four part series which will discuss some financial and legal implications of adding a hog barn to an …

Evidence For Height And Immune Function Trade-Offs Among Preadolescents In A High Pathogen Population, Angela R. Garcia, Aaron Blackwell, Benjamin C. Trumble, Jonathan Stieglitz, Hillard Kaplan, Michael Gurven

ESI Publications

Background

In an energy-limited environment, caloric investments in one characteristic should trade-off with investments in other characteristics. In high pathogen ecologies, biasing energy allocation towards immune function over growth would be predicted, given strong selective pressures against early-life mortality.

Methodology

In the present study, we use flow cytometry to examine trade-offs between adaptive immune function (T cell subsets, B cells), innate immune function (natural killer cells), adaptive to innate ratio and height-for-age z scores (HAZ) among young children (N = 344; aged 2 months–8 years) in the Bolivian Amazon, using maternal BMI and child weight-for-height z scores (WHZ) as …

The Quest For Greener Pastures: Evaluating The Livelihoods Impacts Of Providing Vegetation Condition Maps To Pastoralists In Eastern Africa, Elia Machado, Helene Purcell, Andrew M. Simons, Stephanie Swinehart

Publications and Research

The survival of millions of pastoral households in Eastern Africa has become increasingly at risk. Due to mounting socioeconomic and climatic stressors, pastoral households are faced with making migration decisions under increasing uncertainty about resource availability and limited coping strategies. We assess the potential of providing vegetation condition maps to support the migration decision of pastoralists in Ethiopia and Tanzania and the effect of map usage on their herd condition and size. The maps were generated from remotely sensed data using the Normalized Difference Vegetation Index (NDVI) as a proxy for vegetation condition and overlain with pastoralists’ preferred grazing areas. …

Multiplex Network Ties And The Spatial Diffusion Of Radical Innovations: Martin Luther’S Leadership In The Early Reformation, Sascha O. Becker, Yuan Hsiao, Steven Pfaff, Jared Rubin

ESI Publications

This article analyzes Martin Luther’s role in spreading the early Reformation, one of the most important episodes of radical institutional change in the last millennium. We argue that social relations played a key role in its diffusion because the spread of heterodox ideologies and their eventual institutionalization relied not only on private “infection” through exposure to innovation but also on active conversion and promotion of that new faith through personal ties. We conceive of that process as leader-to-follower directional influence originating with Luther and flowing to local elites through personal ties. Based on novel data on Luther’s correspondence, Luther’s visits, …

Menu-Dependent Food Choices And Food Waste, Hongxing Liu, Joaquín Gómez-Miñambres, Danyi Qi

ESI Working Papers

We use a combination of randomized field experiments and online surveys to test how the menu design affects food choices and food waste. In our field experiment, participants face one of two menus: a narrow menu that only displays a small portion of food, or a broad menu that also contains bigger portions. While all options are equally available in both menus, they differ in how easy and fast the different choices can be made. Our results show that, compared to the broad menu, participants in the narrow menu ordered smaller portions of food. Importantly, food intake was similar across …

What Are Total Export Commitments Telling Us About Beef’S Potential In 2020: Positive Signs?, Elliott James Dennis

Extension Farm and Ranch Management News

Overarching Market Conditions

The recent cattle on feed report suggests that cattle feedlots are coming closer to sorting through much of the backlog associated with plant closures and shutdowns as a result of plant workers testing positive for COVID-19 and plants implementing CDC and OSHA worker health recommendations. For example, the number of cattle on feed over 90 days has dipped below 2019 levels for the first time since April. However, cattle on feed over 120 days is still about 10% higher than 2019. The result of cattle being on feed longer is sustained record level dressed weights for both …

A Notion Of Prominence For Games With Natural-Language Labels, Alessandro Sontuoso, Sudeep Bhatia

ESI Working Papers

We study games with natural-language labels (i.e., strategic problems where options are denoted by words), for which we propose and test a measurable characterization of prominence. We assume that – ceteris paribus – players find particularly prominent those strategies that are denoted by words more frequently used in their everyday language. To operationalize this assumption, we suggest that the prominence of a strategy-label is correlated with its frequency of occurrence in large text corpora, such as the Google Books corpus (“n-gram” frequency). In testing for the strategic use of word frequency, we consider experimental games with different incentive structures (such …

A Simple, Ecologically Rational Rule For Settling Found Property Disputes, Bart J. Wilson

ESI Publications

Who has property in a found item X, which is contained in Y? The finder of X or the person who has property in Y? The common law says it depends. It depends upon whether the owner of Y knew about X, or whether X was lost or mislaid, or how small the weight of X is relative to Y (as compared to its value), or whether the finder was an employee of the owner of Y, to name just a few. Wilson (2020) hypothesizes that humans universally cognize property as being contained in a …

Trust And Trustworthiness In Procurement Contracts With Retainage, Matthew J. Walker, Elena Katok, Jason Shachat

ESI Working Papers

In complex procurement projects, it is difficult to write enforceable contracts that condition price upon quality. Supplier non-performance becomes an acute risk, particularly when there is intense competition for the contract. An established incentive mechanism used to mitigate the problem of supplier non-performance is retainage, in which the buyer sets aside a portion of the purchase price. After project completion, the buyer determines the amount of retainage that is released to the seller, considering any defects that arise. While generally a feasible contract form to implement, the practical difficulties in assessing completion introduce a moral hazard for the buyer. We …

Consistent Differences In A Virtual World Model Of Ape Societies, Bart J. Wilson, Sarah F. Brosnan, Elizabeth V. Lonsdorf, Crickette M. Sanz

ESI Publications

Practical and ethical constraints limit our ability to experimentally test socioecological theory in wild primates. We took an alternate approach to model this, allowing groups of humans to interact in a virtual world in which they had to find food and interact with both ingroup and outgroup avatars to earn rewards. We altered ratios and distributions of high- and low-value foods to test the hypothesis that hominoids vary with regards to social cohesion and intergroup tolerance due to their feeding ecology. We found larger nesting clusters and decreased attacks on outgroup competitors in the Bonobo condition versus the Chimpanzee condition, …
