- Applying the principles of public finance, why should or should not the governments play a role in vaccination? (Please keep in mind, this assignment is NOT an opinion survey. It is an analytical assignment where the principles of public finance must be applied in your argument. The key assumption is that if the issue exhibits signs of market failure then it may provide reasons for government roles. Sample questions to ask include but not limited to: ---Is vaccination a public good? Yes->more government involvement; no->less government ---Is the vaccination industry a natural monopoly? Yes-> more government involvement; no->less ---To what extent does the vaccination market have information asymmetry? A lot-> more government involvement; no->less ---To what extent does the vaccination issue exhibit externality? A lot-> more government involvement; no->less ---Other reasons?...

- A generalized transducing phage is used to transduce ana- b- c- d- e- recipient strain of E. coli with an a+ b+ c+d+ e+ donor. The recipient culture is plated on variousmedia with the results shown in the following table.(Note that a- indicates a requirement for A as a nutrient,and so forth.) What can you conclude about the linkageand order of the genes?T or F A household is frequently used in analyses because more consistent data are usually collected at that level.(Yi, X1i, X2i) satisfy the assumptions of the attachment. You are interestedin β1, the causal effect of X1 on Y. Suppose that X1 and X2 are uncorrelated.You estimate β1 by regressing Y onto X1 (so that X2 is not included in theregression). Does this estimator suffer from omitted variable bias? Explain.
- The model initial setup is• The number of vacancies posted in the economy during a particular month is v = 100.• There were initially u = 225 unemployed workers at the beginning of the month.• Suppose that the average wage is 0.6 relative to their productivity. Unemployed workersreceive benefits that are half the wage, i.e., b = 0.3 relative to productivity.• Suppose that the number of matches between firms and workers are given by thefollowing matching functionsM = Au^0.5v^0.5• Suppose that 45 workers were able to find a job by the end of the month.Answer the following questions.a) What is the monthly job finding rate?b) What is the probability that an average vacancy is filled in a month?c) What is the job creation cost, k?d) What is the value of A?e) Explain how introducing a searching cost to this model would affect the queue length,the number of vacancy and unemployment rate, and wage.26. A mail order company has conducted a survey to assess whether at least 95% of their customers are satisfied with their most recent order. The results show that of the 280 customers asked, 270 said they were satisfied, with the final 10 saying they were dissatisfied. They have asked you to A conduct a hypothesis test at the 5% level to assess whether there is sufficent evidence to show that more than 95% of their customers are satisfied. What should your null and alternative hypotheses be? Ho:u = 0.95 H1:µ > 0.95 Ho:µ > 0.95 H:µ = 0.95 Ho:u 0.95 = 0.95 H: µ + 0.95 Ho:µ + 0.95 H:µ = 0.95Explain what multicollinearity .
