Document Summary

Hazardous weather is either imminent or occurring within the forecast area. A surface or upper-level chart that interprets the present weather patterns. A forecast of an extended period of dry weather would be made for a region beneath: Suppose it is warm and raining, and a cold front is moving toward your location. Directly behind the cold front, it is cold and snowing. Still further behind the front, the weather is cold and clearing. If the front is scheduled to pass your area in 6 hours, a persistence forecast for your area for 12 hours from now would be: The least accurate forecast method of predicting the weather two days into the future during changeable weather conditions is usually the: Weather forecast that predicts that the future weather will be the same as the present weather is called: A persistence forecast could be quite accurate when: You are positioned in the middle of a large, stationary air mass.

Public Goods: Suppose that weather forecast system requires funding in billion-dollar chunks, and that every billion dollars invested in weather forecasting double your odds of getting the forecast right that if you spend nothing your forecast, pure chance, has only a 50% chance of being right; that if you spend $1B your forecast has a 75% chance of being right, that if if you spend $2B your forecast has an 87.5% chance of being right, and so forth.

a) Suppose that for an average person the cost of getting the weather forecast consistently wrong over the life of the system is $100. If there are a million people in the area, how much should the government spend on weather forecasting?

b) Suppose that for an average person the cost of getting the weather forecast consistently wrong over the life of the system is $1000. If there are five million people in the area, how much should the government spend on weather forecasting?

c) Suppose that someone decided it would be a good idea to privatize the weather forecasting system to have a private company broadcast the forecast over media and internet, and collect money by subjecting people to annoying ads while they listen to the forecast. Would this be sustainable equilibrium or not?

14. Application: demand elasticity and agriculture

Consider the market for soybeans. The following graph shows the weekly demand for soybeans and the weekly supply of soybeans. Suppose a spell of unusually good weather occurs, which enables soybean producers to generate more soybeans per acre of land.

Show the effect this shock has on the market for soybeans by shifting the demand curve, supply curve, or both.

One of the growers is concerned about the price decrease caused by the spell of good weather because he feels it will lower the revenue in this market. As an economics student, you can use elasticities to determine whether this change in price will lead to an increase or decrease in total revenue in this market.

Using the midpoint method, the price elasticity of demand for soybeans between the prices of $10 and $6 per bushel is.........., which means that the demand is............between these two points. Therefore you would tell the grower that his claim is...........because total revenue will............as a result of the spell of good weather.

Confirm your conclusion by calculating total revenue in the soybean market before and after the spell of good weather. Enter these values in the following table.

Before the spell of good weather After the spell of good weather

Total Revenue(millions of dollars)
