Adam Smith had many views that helped in making the world what it is today. I can’t imagine what the world would be like if there weren’t thinkers like Adam Smith. Going to college would be pointless and trying to be something more than a cashier in a little store down the street would be pointless. What would we be working so hard for if we made the same amount of money as when we were sixteen working in that little store? He had many other views that were just as important but this was a big interest to me as probably to many others. Smith believed that a nation's wealth was not derived by how much they had in resources, or in exchangeable products, but rather by the labor that people put into making that product. "The annual labor of every nation is the fund which originally supplies it with all the necessaries and conveniences which it annually consumes." Smith stated that a nation could increase the efficiency of the potential of its people by increasing skill and proportion. Smith noted that the best way to increase the efficiency of labor is the division of labor. The division of labor is the central factor in Smith’s theory of economic growth. Division of labor is the splitting of a large task into smaller tasks and then having one person is responsible for only one or two of the smaller tasks, which leads to an increase in productivity and stimulates the entire growth cycle, which increases the efficiency of the whole task. The division of labor and the accumulation of capital are what Adam Smith believed to be the driving forces of economic growth in any nation. He found that when the division of labor had broken down the production into a series of simple operations it was more natural for tools and machinery to be invented that replace hand labor and made everything go faster. Then it increased worker productivity. This increased productivity and combined with the growing production so it increased output. This made more resources available to society to enjoy higher standards of living standard of living and products were not as scarce as they once were. Then Smith noticed that there was a huge rise in the â€Å"wealth of the nation†. Adam Smith stated that what a product is worth depends on the amount of labor that must be used to make that product.

Decision Model Theory Essay

Case Here we use the Thompson Lumber Company case as an example to illustrate these decision theory steps. John Thompson is the founder and president of Thompson Lumber Company, a profitable firm located in Portland, Oregon. Step 1 The problem that John Thompson identifies is whether to expand his product line by manufacturing and marketing a new product, backyard storage sheds. Step 2 * The second step is to list the alternative. * Thompson’s second step is to generate alternatives that are available to him .In decision theory the alternative is a course of action or strategy that the decision maker can choose .According to him his alternatives are to construct: 1†¢ a large new plant to manufacture the storage sheds 2†¢ a small plant, or 3†¢ no plant at all * So, the decision makers should try to make all possible alternatives ,on some occasion even the least important alternative might turn out to be the best choice. Step 3 * Third step is to identify possible outcomes. * The criteria for action are established at this time. According to Thompson there are two possible outcomes: the market for the storage sheds could be favorable means there is a high demand of the product or it could be unfavorable means that there is low demand of the product. * Optimistic decision makers tend to ignore bad outcomes; where as pessimistic managers may discount a favorable outcome. If you don’t consider all possibilities, it will be difficult to make a logical decision, and the result may be undesirable. * There may be some outcomes over which the decision maker has little or no control is known as states of nature. Step 4 * Fourth step is to list payoffs. * This step is to list payoff resulting from each possible combination of alternatives and outcomes. Because in this case he wants to maximize his profits, he use profits to evaluate each consequences .Not every decision, of course, can be based on money alone – any appropriate means of measuring benefit is acceptable. In decision theory we call such payoff or profits conditional values. Step 5 & 6 * The last two steps are to select and apply the decision theory model. * Apply it to the data to help make the decision. Selecting the model depends on the environment in which you are operating and the amount of risk and uncertainty involved. * Decision Table with condition values for Thompson TYPES OF DECISION MAKING ENVIRONMENTS * The types of decisions people make depends on how much knowledge or information they have about the situation. There are three kind of decision making environments: * Decision making under certainty. * Decision making under risk. * Decision making under uncertainty. Decision Making Under Certainty * Here the decision makers know about the certainty of consequences every alternative or decision choice has. * Naturally they will choose the alternative that will result in the best outcome. * Example: Let’s say that you have $10000 to invest for a period of one year. And you have two alternatives either to open a savings account paying 6% interest and another is investing in Govt. Treasury Bond paying 10% interest. If both the investments are secure and guaranteed, the best alternative is to choose the second investment option to gain maximum profit. Decision Making Under Risk * Here the decision Maker knows about the several possible outcomes for each alternative and the probability of occurrence of each outcome. * Example: The probability of being dealt a club is 0.25. The probability of rolling a 5 on die is 1/6. * In the decision making under risk, the decision maker usually attempts to maximize his or her expected well being. Decision theory models for business problems in this in this environment typically employ two equivalent criteria: maximization of expected monetary value and minimization of expected loss. * Expected monetary value is the weighted value of possible payoffs for each alternative Decision Making under Uncertainty * Here there are several outcomes for each alternative, and the decision maker does not know the probabilities occurrences of various outcomes. * Example The probability that a Democrat/Republican will be the President of a country 25 Years from now is not known. * The criteria that is covered in this section as follows: 1 – Maximax †¢ this criterion find the alternative that maximizes the maximum payoffs or consequence for every alternative. Here we first locate the maximum payoff with every alternative and then pick that alternative with the maximum number. This is also known as optimistic decision criterion. * Maximin †¢ this criterion finds the alternative that maximizes the minimum payoff or consequence for every alternative. Here we first locate the minimum outcome within every alternative and then pick that alternative with maximum number. This is called as pessimistic decision criterion. * Criterion of Realism: Also called as weighted average, is a compromise between an optimistic and a pessimistic decision. Let the coefficient of realism is ‘a’ selected. The coefficient is between 0 and 1. When ‘a’ is close to 1, the decision maker is optimistic about the future. When ‘a’ is close ‘0’ the decision maker is pessimistic. It helps the decision maker to build feelings about relative optimism and pessimism. * Weighted average =a (maximum in row) + (1-a)(minimum in row). * Equally likely (Laplace)-one criterion that uses all the payoffs for each alternative is the equally likely also called Laplace decision criterion. This is to fi nd alternative with highest payoff. * Minimax Regret †¢ the final decision criterion that we discuss is based on opportunity loss or regret. Expected Value of Perfect Information * Formula EVPI = A – B A = expected value with perfect information B = expected value without perfect information Calculation of (A) value: A = the best of each outcome x their prob. The best of outcomes: Best outcome= (100,000) (30,000) A= 0.6 x 100,000 + 0.4 x 30,000 = 72,000 Calculation of (B) value: B = we select the max value of each given below Outcome of each event: 0.6(50000) + 0.4 (30,000)= 42,000 0.6(100,000 -0.4(40,000)= 44,000 0.6(30,000) + 0.4(10,000)= 20,000 The max value for all computed value = 44,000 EVPI = A – B = 72,000 – 44,000 = 28,000 Expected Opportunity Loss The expected opportunity loss is the expected value of the regret for each decision (Minimax) EOL (Apartment) = $50,000(.6) + 0(.4) = 30,000 EOL (Office) = $0(.6) + 70,000(.4) = 28,000 EOL (Warehouse) = $70,000(.6) + 20,000(.4) = 50,000 Marginal Analysis * Most of our decisions are made following our â€Å"marginal analysis† of costs and benefits * To achieve a given outcome we often have to make a choice from among alternative means; we normally try to make the â€Å"least costly† choice among the available means * Sometimes our decisions result in benefits as well as costs; * How much food should you buy? * How many years of schooling should you have? * How many hours should you work? * How many workers should you hire? * How much should save/invest?
