Intuitive Black-Scholes Option Pricing With A Simple Table, Tom Arnold, Terry D. Nixon, Richard L. Shockley Jr.

Finance Faculty Publications

The Black-Scholes option pricing model (1973) can be intimidating for the novice. By rearranging and combining some of the variables, one can reduce the number of parameters in the valuation problem from five to two: 1) the option's moneyness ratio and 2) its time-adjusted volatility. This allows the computationally complex Black-Scholes formula to be collapsed into an easy-to-use table similar to those in some popular textbooks. The tabular approach provides an excellent tool for building intuition about the comparative statics in the Black-Scholes equation. Further, the pricing table can be used to price options on dividend-paying stocks, commodities, foreign exchange …

Research Strategy And Scoping Survey On Spreadsheet Practices, Thomas A. Grossman Jr., O Ozluk

Business Analytics and Information Systems

We propose a research strategy for creating and deploying prescriptive recommendations for spreadsheet practice. Empirical data on usage can be used to create a taxonomy of spreadsheet classes. Within each class, existing practices and ideal practices can he combined into proposed best practices for deployment. As a first step we propose a scoping survey to gather non-anecdotal data on spreadsheet usage. The scoping survey will interview people who develop spreadsheets. We will investigate the determinants of spreadsheet importance, identify current industry practices, and document existing standards for creation and use of spreadsheets. The survey will provide insight into user attributes, …

Microscopic Chaos And Gaussian Diffusion Processes, L. Y. Chew, Christopher Ting

Research Collection Lee Kong Chian School Of Business

In this paper, we construct and analyze a prototypical model of microscopic chaos. In particular, we extend the results of Beck and Shimizu to the case where the microscopic time scale r is no longer small. The upshot is that a non-Ornstein-Uhlenbeck deterministic process can generate a Gaussian diffusion process.

Pricing And Product Mix Optimization In Freight Transportation, Michael F. Gorman

MIS/OM/DS Faculty Publications

We propose improved pricing and market mix can improve the profitability of the freight transportation provider through the reduction of equipment repositioning costs. We hypothesize that because of complexities surrounding pricing and equipment repositioning costing, existing pricing strategies in freight transportation fail to fully consider these costs. We test this hypothesis in an applied setting in which Monte Carlo simulation captures the stochasticity of market conditions inherent in the problem. We use a heuristic to improve the nondifferentiable, discontinuous objective function.

Our results from test cases show with high confidence that current prices are not optimal, as indicated by a …

Miscellaneous Publication 009/2001 - Pistachios Western Australia An Income Producing Reforestation Opportunity For The Wheatbelt, Andrew Quinn

Horticulture published reports

Faced with a rising water-table, salt and acid land impacts, the Western Australian Wheatbelt requires significant changes to traditional farming system models.

Part of this drive towards improved sustainability is the need to re-plant substantial areas to tree belts or blocks. One of the limiting factors in the widescale adoption of on-farm tree planting is the narrow range of opportunities to generate income from these sites.

This report presents a model for the development of a Pistachio nut industry with production integrated into existing Wheatbelt farming systems. In addition to offering significant environmental benefits, the Pistachio tree offers the opportunity …

Developing An Environmental Management System A Practical Guidebook For Agricultural Businesses, Lucy Taylor

A Model To Evaluate The Effect Of Organizational Adaptation, Holly A. H. Handley, Alexander H. Levis

Engineering Management & Systems Engineering Faculty Publications

When an organization’s output declines due to either internal changes or changes in its external environment, it needs to adapt. In order to evaluate the effectiveness of different adaptation strategies on organizational per- formance, an organizational model composed of individual models of a five stage interacting decision maker was designed using an object oriented design approach and implemented as a Colored Petri net. The concept of entropy is used to calculate the total activity value, a surrogate for decision maker workload, based on the functional partition and the adaptation strategy being implemented. The individual decision maker’s total activity is monitored, …

Fisheries Research Report No. 123 - Review Of Productivity Levels Of Western Australian Coastal And Estuarine Waters For Mariculture Planning Purposes, Alan Pearce, Stuart Helleren, Mark Marinelli, Fisheries Western Australia

Fisheries Research Reports

The measurement of chlorophyll-a (a simple estimate of phytoplankton biomass) is often used as an indicator of water quality. Chlorophyll measurements are relatively sparse for most of the Western Australian continental shelf, although there are areas such as the Perth metropolitan coastal zone, Wilson Inlet and the Albany harbours where some intensive studies have been undertaken.

This review of both published and unpublished chlorophyll concentrations in Western Australian waters has shown a high degree of variability in space (both horizontally and vertically) and time, and statistics on the seasonal distribution of chlorophyll have been derived for those regions with sufficient …

Commercial Irrigation And Nutrition Practices For Strawberries In Western Australia, D. Phillips, D. Gatter, T. Calder, D. Pitman

Horticulture research reports

Irrigation practices employed by five commercial strawberry growers on sandy soils of the Swan Coastal Plain near Perth Western Australia were monitored for two consecutive seasons, 1995 and 1996 during the Spring production period.

Nutritional practices for the same grower group plus one Albany grower were monitored by plant, soil and sap analysis at 14 day intervals throughout the 1996 season.

Irrigation records showed that market quality strawberries could be produced at this time of year (August to December in Perth) on soils with very poor water retention properties with an average crop factor(E Pan) for the season of 0.7 …

Combining Multi-Attribute Utility And Geographic Information For Boundary Decisions: An Application To Park Planning, Jeffrey Keisler, Ronald Sundell

Management Science and Information Systems Faculty Publication Series

The quality and value of an area depend primarily on what is found within its designated boundaries. To determine the value of such areas in terms of boundaries, we have developed a methodology for integrating multi-attribute utility functions with spatial analysis so that desirable, or appropriate, boundaries can be determined on the basis of the goals and objectives for the park. The key to successful evaluation is the development of measures for what decision makers value, rather than merely using what is easily measured. In a detailed example for planning of national parks, the fundamental objectives are conservation and societal …

Pink snapper, Chrysophrysauratus (Sparidae) is one of the major commercial and recreational fish in Western Australian inshore waters. This report presents a number of equations and conversion factors for management and scientific study of the species. Equations to calculate total lengths from partial lengths will facilitate enforcement of minimum legal lengths when snapper are landed in a "head-off" condition. For fisheries science purposes, there are equations to convert among total length, standard length and length to caudal fork; and to convert lengths and weights of processed fish to whole lengths and weights. Length-weight relationships are presented and compared with those …

Fisheries Research Report No 99 - An Investigation Of Weight Loss Of Marron (Cherax Tenuimanus) In Air During Live Transport To Market, Noel Morrissy, Peter Walker, Cliff Fellows, Warren Moore

Fisheries Research Reports

It is generally acknowledged that more competitive marketing of Australian fisheries and aquaculture harvests requires closer attention to post-harvest technology. Historically, these products have been marketed in a variety of forms (e.g., for freshwater crayfish:- boiled fresh, boiled frozen, whole or tails, and live). Some of these forms present a product of actual, or perceived, poorer quality to the retailer and consumer and, thereby, obtain low prices.

Freshwater crayfish can survive out of water for extended periods and, so, can be economically transported alive to the (overseas) restaurant chef. This live product commands the very highest price for the grower. …
