Contractor Dittmar is bidding on a job that he expects will cost him \(\$ 500,000\) to complete. Dittmar has excess capacity and can take on the new job. Several other contractors, including the firm of Causey and Grasso, are bidding on the same job. Dittmar has bid against this company in the past and feels that he has some knowledge about how they are likely to bid. In the following table, Dittmar has estimated the subjective probabilities of winning for any bid he makes. (a) Sketch a graph of these probabilities. (b) What should Dittmar's optimal strategy be?

Short Answer

Expert verified
(a) After plotting the subjective probabilities of winning for each bid amount on a graph, we can visually represent how Dittmar's probability of winning the job changes depending on his bid amount. (b) Dittmar's optimal strategy can be determined by identifying the bid amount that maximizes his probability of winning the job while still being above the expected cost of $500,000. If the optimal bid amount satisfies these conditions, that would be Dittmar's optimal strategy. If not, he may need to consider a different strategy or reassess his expected costs to ensure he doesn't incur a loss. A table of probabilities is crucial to conduct this analysis.

Step by step solution

01

Analyze the given data

First, we will analyze the given data. We are given a table of subjective probabilities of winning for any bid Contractor Dittmar makes. To proceed, please provide the table of probabilities.
02

Plot the probabilities on a graph

Once the table of probabilities is given, plot the probabilities on a graph. 1. Label the x-axis "Bid amount" and the y-axis "Probability of winning." 2. For each bid amount in the table, plot a point corresponding to the bid amount and the probability of winning. 3. Connect the adjacent points with straight lines. After following these steps, the graph will give us a visual representation of how Dittmar's probability of winning the job changes depending on his bid amount.
03

Analyze the graph to determine Dittmar's optimal strategy

To find Dittmar's optimal bidding strategy, we will analyze the graph and determine the following: 1. Identify the bid amount that maximizes the probability of winning the job. 2. Compare this bid amount to the expected costs of completing the job, which is given as $500,000. If the optimal bid amount maximizes the probability of winning while still being above the expected cost, this bid amount would be Dittmar's optimal strategy. If not, he may need to consider a different strategy or reassess his expected costs to ensure he doesn't incur a loss. Please provide the table of probabilities to create the graph and analyze it accordingly.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Probability of Winning
Understanding the probability of winning is a cornerstone of strategic bidding. It's an assessment of how likely a bidder is to secure a contract based on their bid amount. In Contractor Dittmar's scenario, the probability of winning represents his chances of success against competitors when bidding for a job.

In practical terms, a probability graph helps to visualize this likelihood. The X-axis displays different bid amounts, while the Y-axis reflects the corresponding chances of securing the job. By plotting points based on Dittmar's subjective probabilities and connecting them, he can discern how his odds of winning fluctuate with each potential bid.

This visual tool is invaluable as Dittmar considers bids both below and above the threshold of his expected costs, allowing him to adjust his strategy accordingly. The objective is to locate a bid value that maximizes his chances without undercutting his profitability. This sweet spot is critical, as bidding too high might lose the bid, while bidding too low could undermine his earnings.
Cost Estimation
Cost estimation serves as a financial compass in bid strategy optimization. For Contractor Dittmar, a firm grip on cost estimation means knowing his exact expenses to complete the job, which is pegged at $500,000. Having such a figure is critical because it sets the baseline for his bid amounts.

To optimize his bid, Dittmar will consider this cost estimate and add a margin. This addition will account for profit, as well as any uncertainties or variations that might emerge during the project. Creating a buffer above the estimated costs can protect Dittmar from unforeseen expenses and ensure the job remains profitable, even if the actual costs exceed initial projections.

It's imperative that Dittmar's bid satisfies two conditions: it must be high enough to cover costs and desired profit, yet also competitive enough to have a reasonable shot at winning the contract. Thus, the link between cost estimation and bid strategy is incontestable. Dittmar will employ his knowledge of both fixed and variable costs to inform his bidding strategy.
Subjective Probabilities
Subjective probabilities are individual beliefs about the likelihood of an event occurring, based on personal judgment instead of objective data. Contractor Dittmar's experience bidding against firms like Causey and Grasso informs these probabilities. Rather than relying on historical data alone, he incorporates his intuition about his competitors' bidding behavior into his decision-making process.

Incorporating subjective probabilities into bid strategy can be tricky, but also advantageous. Dittmar's nuanced understanding of his competitors allows him to adjust his bid in a way that might not be evident through objective data alone. However, the subjective nature of this method means it's also fraught with the potential for error due to cognitive biases.

To balance this, Dittmar could maintain an adaptive approach, updating his subjective probabilities as more information becomes available or as he gains further insight into his competitors' strategies. By doing so, he aligns his intuition with an evolving competitive landscape, potentially enhancing his chances of formulating a winning bid.

You are the president of a company that makes wrist watches. The prestige line of watches, Chronomatrix 1536 is waterproof, shockproof, dustproof and features anti-magnetic movement. This watch is sold to distributors for \(\$ 25\) apiece. Your vice-president suggests that a guarantee to replace watches that fail within two years of purchase would allow a price increase of \(\$ 2.00\) per watch without a decrease in demand. The engineering department assures you that the lifetimes of the Chronomatrix 1536 follow some unknown probability distribution with mean \(\mu=3.5\) years and \(\sigma=0.5\) years. If sales remain constant at 100,000 watches per year and a replacement watch would cost \(\$ 15.00\), is this a profitable policy for your company?

Graph the following time series $$ \begin{array}{|l|l|} \hline \text { Year } & \text { Soap Purity as Percentage of Total } \\ \hline 1955 & 99.0 \\ 1956 & 99.0 \\ 1957 & 98.3 \\ 1958 & 98.1 \\ 1959 & 98.2 \\ 1960 & 98.6 \\ 1961 & 98.8 \\ 1962 & 98.3 \\ 1963 & 98.0 \\ \hline \end{array} $$

A contractor has found through experience that the low bid for a job (excluding his own bid) is a random variable that is uniformly distributed over the interval \((3 \mathrm{c} / 4,2 \mathrm{c})\) where \(\mathrm{c}\) is the contractor's cost estimate (no profit or loss) of the job. If profit is defined as zero if the contractor does not get the job (his bid is greater than the low bid) and as the difference between his bid and the cost estimate \(\mathrm{c}\) if he gets the job, what should he bid, in terms of \(\mathrm{c}\), in order to maximize his expected profit?

The Kannan Manufacturing Company is going to build a new plant. Kannan can either build a large plant or a small one with the option of expanding the small one if feasible. Kannan is uncertain of the demand for his product, but he does know that it will be high with a probability of \(0.6\) and low with a probability of \(0.4 .\) For a large plant and high demand net profit is \(\$ 6\) million; and if the demand is low, the payoff is \(\$ 1\) million. Similarly, if a small plant is built initially and no expansion is made the net profits are \(\$ 4\) million (high demand) and \(\$ 3\) million (low demand). There is a net profit of \(\$ 5\) million with expansion of a small plant in the face of high demand. This is determined as follows: Profit from high demand (with production ability to meet demand). \(\$ 10\) million Less: Cost of building small plant \(\$ 2\) million Cost of expanding 3 million Total cost 5 million Payoff \(\$ 5\) million Similarly, expanding in the face of low demand costs the \(\$ 5\) million as above and only has a profit of \(\$ 5\) million. The net profit is zero. Should Kannan build a large or a small plant?

A research worker was interested in racial differences in the standard of living of farm operators in the southeastern United States. He used the presence of running water in farm dwellings as a crude index of the standard of living. For each of 31 economic areas in North Carolina, South Carolina, and Georgia in 1945, he calculated two measures: \(\mathrm{X}=\) farms operated by nonwhites per 100 white farm operators and \(\mathrm{Y}=\) percent of farms having running water in dwellings. The following values were obtained: $$ \begin{array}{lll} \sum \mathrm{X}=1,860 & \sum \mathrm{Y}=465 & \sum \mathrm{XY}=23,400 \\ \sum \mathrm{X}^{2}=201,600 & \sum \mathrm{Y}^{2}=7,925 & \mathrm{n}=31 \end{array} $$ Compute the regression line and the correlation of \(\mathrm{X}\) and \(\mathrm{Y}\).
