- ItemThe Mediation of Variance Conflicts: An Empirical Evaluation(Department of Food and Resource Economics, 2000-09) Duke, Joshua M.; Jost, Ryan P.Since 1982, the New Castle County Superior Court in Delaware has promoted mediation, which attempts to resolve filed conflicts prior to trial. This paper evaluates how spatial land-use conflicts channel through mediation and litigation. Data suggest that mediations fail because one of the key disputing parties does not play a direct role in mediation and litigation. The data then inform a predictive model of litigated outcomes in which disputants share in the responsibility for conflict. By alleviating some of the uncertainty of litigation and proposing win-win, mediated outcomes, the model may be used facilitate future mediations.
- ItemIn-Patient Flow Analysis Using ProModelTM Simulation Package(Food and Resource Economics Department, 2000-11) Elbeyli, Sema; Krishnan, PalaniappaThis paper emphasizes the basic modeling approach of general in-patient flow in a major hospital in the East Coast region. Simulation was used to analyze the inpatient flow. The first objective of this study was to determine the bottlenecks for in-in-patient flow. In order to understand the general in-patient flow, some emphasis was also given to the other units such as Medical-Surgical, Telemetry, Intensive Care Units (ICU), etc. Second objective was to study the impact of bed availability on the waiting time of admitted patients in ED before being transferred to assigned beds in other units of the hospital. A preliminary model was developed and validated based on the data collected for the selected time periods (busy four months). Different “what-if” scenarios were studied. This paper presents the basic model and its results.
- ItemSequential Land Acquisition for Nature Reserves under Acquisition and Population Uncertainty.(Food and Resource Economics, 2001-01) Malcolm, Scott A.Nature reserve planning models to maximize species protection are typically formulated for a single period using certain data. In practice, however, parcels must be acquired over time. The status of a parcel may change due to conversion to alternate land use. Populations of species to be protected may change, as well. A twostage stochastic program that maximizes expected species protection with annual budget constraints is proposed where parcels available for set aside have associated probabilities of being available for acquisition and species coverage. Runs on hypothetical data show that solutions differ from the single period model and depend strongly on the probability of acquisition in future periods.
- ItemIs the Export-Lead Growth Hypothesis Valid for Canada?(Department of Food and Resource Economics, 2002-03) Awokuse, TitusEmpirical evidence linking exports to economic growth has been mixed and inconclusive. This study re-examine the export-led growth (ELG) hypothesis for Canada by testing for Granger causality from exports to national output growth using vector error correction models (VECM) and the augmented vector autoregressive (VAR) methodology developed in Toda and Yamamoto (1995). Application of recent developments in time series modeling and the inclusion of relevant variables omitted in previous studies help clarify the contradictory results from prior studies on the Canadian economy. The empirical results suggest that a long-run steady state exists among the model’s six variables and that Granger causal flow is unidirectional from real exports to real GDP.
- ItemThe Informational Role of Commodity Prices in Formulating Monetary Policy: A Reexamination(Department of Food and Resource Economics, 2002-06) Awokuse, Titus; Yang, JianThis paper reexamines the issue of whether commodity prices provide useful information for formulating monetary policy through the application of recent development in time series methodology developed by Toda and Yamamoto (1995). We found that commodity prices signals the future direction of the economy.
