How Economists Define and Measure Treatment Effects

The term treatment effect  is defined as the average causal effect of a variable on an outcome variable that is of scientific or economic interest. The term first gained traction in the field of medical research where is originated. Since its inception, the term has broadened and has begun to be used more generally as in economic research. Treatment Effects in Economic Research Perhaps one of the most famous examples of treatment effect research in economics is that of a training program or advanced education. At the lowest level, economists have been interested in comparing the earnings or wages of two primary groups: one who participated in the training program and one who did not. An empirical study of treatment effects generally begins with these types of straightforward comparisons. But in practice, such comparisons have the great potential to lead researchers to misleading  conclusions of causal effects, which brings us to the primary problem in treatment effects research. Classic Treatment Effects Problems and Selection Bias In the language of scientific experimentation, a treatment is something done to a person that might have an effect. In the absence of randomized, controlled experiments, discerning the effect of a treatment like a college education or a job training program on income can be clouded by the fact that the person made the choice to be treated. This is known in the scientific research community as selection bias and, it is one of the ​principle  problems in the estimation of treatment effects. The problem of selection bias essentially comes down to the chance that treated individuals may differ from non-treated individuals for reasons other than the treatment itself. As such, the outcomes such treatment would actually a combined result of the persons propensity to choose the treatment and the effects of the treatment itself. Measuring the treatments true effect while screening out the effects of selection bias is the classic treatment effects problem. How Economists Handle Selection Bias In order to measure true treatment effects, economists have certain methods available to them. A standard method is to regress the outcome on other predictors that do not vary with time as well as whether the person took the treatment or not. Using the previous edition treatment example introduced above, an economist may apply a regression of wages not only on years-of-education but also on test scores meant to measure abilities or motivation. The researcher may come to find that both years-of-education and test scores are positively correlated with subsequent wages, so when interpreting the findings the coefficient found on years of education has been partly cleansed of the factors predicting which people would have chosen to have more education. Building upon the use of regressions in treatment effects research, economists may turn to what is known as the potential outcomes framework, which was originally introduced by statisticians. Potential outcomes models use essentially the same methods as switching regression models, but potential outcomes models are not tied to a linear regression framework as are switching regressions.  A more advanced method based upon these modeling techniques is the Heckman two-step.

The Tell Tale Heart Analysis - 1295 Words

Klinger, Sabrina - Midterm Exam Explain the term ‘unreliable narrator’. How does this point of view complicate the plot in Poe’s, The Tell-Tale heart? An unreliable narrator is a narrator whose credibility has been seriously compromised whether it be in literature, film or theatre. Such as providing faulty, misleading or distorted details. The narrator in this short story is the killer. We really do not get the opportunity to really know the killer such as his name and what his motive is in killing the old man. What we do learn is he displays no guilt and he is not â€Å"mad†. He also appears to be proud of what he has done. The killer is very nonchalant in telling how he killed the old man and the reasoning behind doing so has to do with†¦show more content†¦Discuss the conflict in John Updike’s AP. Why does it not get resolved? AS discussed in the video there are a few conflicts presented. Generational conflict is one. This occurs as Lengel is an older man and the 3 gir ls are younger and what he sees as appropriate may not be the same as how the girls see it. The 2nd conflict would be conflict of ethics. We are told that Lengel is a religious man as he teaches Sunday school. This conflict could be seen as a difference of values. Lastly, the most important conflict in this story is Shame. For example, Queenie blushes when first addressed by Lengel. She then goes onto explain why they are in the store. It is when Lengel says that â€Å"we want you dressed decently† that Queenie responds with â€Å"we are decent.† It is obvious the Queenie was experiencing embarrassment over how Lengel suggested otherwise. The conflict in this story does not get resolved due to everyone having their own opinions on what is decent. Discuss the irony of the statement, When the doctors came they said she had died of heart disease-of joy that kills, in The Story of an Hour. One of the very first things we learn is Mrs. Mallard was afflicted with heart trouble. In the last sentence of this story we learn she dies of heart disease – of joys that kill.

I gave them a list of examples and connected them with work examples. Unfortunately, it came off like a typical laundry list. Boring, forgettable, and â€Å"toss salad†. Not surprisingly, I was O for 4 in getting my rumination. Then, in my 5th promotion interview, when I got the same question, I twisted the question. Instead of making the same mistake again, I actually asked, â€Å"What are the challenges for your unit? † Then, after listening patiently to their challenges, I was able to make everything I said relevant for their unit.
