STATA analysis
Part 1. Initial Outline
Items in round brackets are optional depending on the question. Economics 381 deals with items in square
brackets. You can leave these sections until you get to that course.
(1) Introduction
(a) Research question
(i) What is the main connection you are working on?
(A) What are the variables?
(B) What is the direction of causality?
(ii) What parameters are you trying to measure?
(A) In what units will the parameters be measured?
(b) (Policy analysis)
(i) How does answering the question contribute to policy making?
(ii) How important is the policy involved?

(2) [Literature Survey](3) The Model
(a) What other connections besides those identi?ed in 1(a)i will you include in the analysis?
(b) The path diagram
(i) What are the causal connections?
(ii) What are connections that represent covariance?
(iii) What are the signs of the relationships represented by all the paths?
(c) What mathematical speci?cation will you use as your base model (i.e. before any respeci?cation
based on analysis of the ?rst regression results)?
(4) The Data
(a) What is the source of the data?
(b) [How are the variables in the model operationalized?]
(c) What are the univariate properties of the data?
(i) Central tendency
(ii) Spread
(iii) Shape
(iv) Pattern and exceptions

12(d) What are the multivariate properties of the data?
(i) What are the partial correlations for the paths in your model under 3b?
(ii) (Are there any issues you need to deal with as a result of the analysis for outliers in 4(c)iv?
(5) The results
(a) What are the results of the estimation of your base model?
(i) Estimates
(A) For each estimate, the reults of the hypothesis test, and an interpretation
(B) Does the result match the prediction of the direction of the relationship in 4(c)iv?
(C) How well does the sample prediction function explain the dependent variable?
(ii) Assessment of the speci?cation
(A) Do the residuals appear to match the assumption of independence from any of the
included variables?
(B) Can we leave out any of the independent variables based on tests of exclusion restrictions?
(C) If you�ve decided to, what modi?cations did you make to the base model (e.g adding
or removing variables, transforming the dependent or independent variables, etc.)
(D) Repeat 5(a)i and 5(a)ii.
(6) Conclusions
(a) What answer(s) to the main research question(s) do the results of your work provide?
(b) (What are the policy implications of these answers?)
(c) [What limitations are your answers subject to?]
