1. Use the data to estimate a simple regression equation of the following form:
catcht  = b0  +b1effortt + et
Report your findings in either table or equation form. Does this regression satisfy CR3? Please show and explain your test for serial correlation at the 95% significance level. Present your results and explain your conclusion
2. Please specify and estimate a better regression model that you can defend, on the basis of economic theory, to explain the production of tuna as a function of effort. Explain why this functional form is better. Present and interpret your results. What is the elasticity of output with respect to effort in this new model?
3. Is serial correlation a problem with the model in (2)?  Please carefully present the results of your test for serial correlation (use the 95% significance level), present your results, and explain your findings.
4. Now re-estimate the model in (2) using the Newey-West method. Report your results and compare them with what you got in (2). What is different, and why?
5. Is there evidence that the marginal product of effort has changed over time?  How? Please show your work, explaining how you test for this and what you find.
6. Does the model in (5) exhibit serial correlation? Please test for this at the 95% level
and present your test results. Is the result different than in (3)? Please speculate on why or why not.
Please answer 2-6 specify as soon as possible . Thank you so much emergency
