This paper establishes a coupled human-ecological model where slow-varying migration is interacting with fast-varying nutrient dynamics in lake ecology. The nonlinearity and fast-slow dynamics built in the model can generate regime shifts (that is, shifts between different equilibrium states)...

We develop a coupled model of regional migration and lake ecology to study the influence of ecological-economic interactions and relative time scales on transient and asymptotic dynamics. Cross-scale interactions fundamentally change system dynamics by eliminating steady states that are present...

We find sale prices and net revenues received by sellers in the Midwestern club pig market are higher at traditional face-to-face auctions than at comparable Internet auctions. The comparison overcomes adverse selection issues that commonly plague such analyses by using data from sellers that...

When products are differentiated and quality is highly subjective (e.g., fashion or art), novel (e.g., a new feature), or difficult to verify prior to purchase (e.g., credence attributes), consumers may turn to price as a signal of quality. Products containing genetically modified (GM)...

This research focuses on developing a biannual net revenue forecasting model for hog producers based on Monte Carlo simulation of the joint distribution of hog, corn and soybean meal price series. The relative forecasting power of historical volatility, implied volatility and GARCH-based...

The form and regulation of contracts is of increasing importance to agricultural economists as farmers and agribusinesses increasing rely on contracts rather than markets to acquire inputs and sell outputs. We focus on the differences between the joint and individual surplus achievable under...

We consider the implications of banning tournament contracts and replacing them with fixed performance standard contracts in a multi-period model where the principal cannot commit to future contract parameters. A ban cannot increase total surplus in a static model. In a dynamic model, however, a...

Experimental economics is used to compare tournaments (T) and fixed performance contracts (F) when agents have heterogeneous costs. Our primary findings were: (1) There is no statistical difference in average pooled effort (effort by high ability and low ability subjects are pooled together to...

Two well-known hypotheses from the literature on tournaments are that (1) tournaments can filter out common shocks thereby reducing agentsÂ’ risk exposure; and (2) disincentive effects can arise when a tournament scheme is administered on a group of mixed ability agents. While handicapping and/or...
