Suppose the difference between matter and antimatter in the early universe were 1 part in 108 instead of 1 part in 109. (a.) Evaluate the temperature at which deuterium begins to form. (b.) At what age does this occur? (c.) Evaluate the temperature and the corresponding time of radiation decoupling (when hydrogen atoms form).

1. Questions about Difference in Differences Consider the following hypothetical scenario. Washington (state) passes a law subsi- dizing child care for working mothers in 2005. Suppose we are interested in examining the impact of this law on the labor supply of women, and we gather data on the hours of work, Hit for a sample of women across the United States, from 2000-2010. Assume also that Oregon has an economy that is similar to that of Washington, but Oregon did...

Question 1 Consider an example of trade between two regions (North and South), similar to the one we discussed in class. The hourly output of workers in the North and South is given by the following table: North | South Shirts 4 2 Bread 1 3 To execute a trade, each shirt/loaf of bread must be brought to the market square. Shirts can be brought to the market square without additional costs, however, each loaf of bread costs d loaves...

1[30%]. This problem is similar to question 2.10 in the text book, except the environment configuration is slightly different. Consider the following vacuum-cleaning world which has 3 squares: We assume the following: The vacuum-cleaning agent knows the configuration of the 3 squares, but does not know which square it is in initially. The initial dirt distribution is not known either. A clean square remains clean and a dirty square remains dirty unless the agent cleans it up. The agent has...

1. Consider a two-period model similar to the one discussed in the class. Assume that the inverse demand equations for a particular depletable resource (e.g., stock of oil) differs across the two periods, with MB. = 600 - 90 MB = 800 - 91 Where, 9. denotes the amount of oil consumed in period 0 and q, denotes the amount consumed in period 1. The higher demand for oil in period 1 might result, for example, from an increased population....

Additional problems 1. Consider a plan to improve lighting on a dangerous section of highway. The improvements involve a one-time cost in year 1 of $5,000,000, would last 8 years, and are expected to reduce the annual number of accidents by 12. A recent report indicates that the average social cost of a motor vehicle crash is $77,000. a) b) Illustrate the timing of the benefits and costs using a timeline. Calculate the net present value of the project, assuming...
