1. Go to Google Scholar and search for: smoking bans
How many search results come up?
Which academic disciplines do you see represented?
What options do you have to narrow down your results?
How are your results sorted? (Can you change the order?)
2. Open a new tab. Go to EconLit and repeat the search.
(keep EconLit open)
Criteria you can use to filter results in EconLit
Geography: Focus on research about a specific country
Filter results Subject > Select country name
Advanced Search Search country name in All Subjects
Publication Date
Publication Title (the journal an article was published in)
>> Search EconLit for tobacco control
Filter by Subject: Select More, then find u.s. in the list.
Check box to Include, then click Apply.
>> Go to Advanced Search.
1st search box: enter a keyword for your policy issue
2nd search box: enter (u.s. OR china OR _____)
Change drop-down menu to All Subjects (then search)
How do you do more complex searches?
Two approaches:
- Search for groups of synonyms (expands results)
- Use abstract + subject searching (helps focus results)
("smoking bans" OR "smoke-free" OR "tobacco control")
(restaurants OR bars OR cafes OR dining)
AND
("smoking bans" OR "smoke-free" OR "tobacco control")
(restaurants OR bars OR cafes OR dining)
--> What this means: An article only needs to include 1 term from each group to appear in your
search results.
Search for Groups of Synonyms
Use Abstract + Subject Searching
Subject Searching: Emphasize an aspect of your topic
Abstract Searching: Increases relevance of your results by showing only articles where your terms are mentioned prominently: in the title, abstract, or description.
>> Do an Advanced Search in EconLit:
1st box: smoke-free
2nd box: L* (change drop-down to All Subjects & Indexing)
This finds articles mentioning "smoke-free" that
are tagged with Industrial Organization
>> Search keyword in Anywhere Except Full Text
For example, compare 2 articles about the Earned Income Tax Credit. Each article emphasizes a different impact (household finances, health). See how these articles are tagged with different JEL Codes:
“The Impact of the Earned Income Tax Credit on Household Finances” | “The Earned Income Tax Credit, Mental Health, and Happiness” |
---|---|
Personal Income and Other Nonbusiness Taxes and Subsidies, includes inheritance and gift taxes (H24) | Personal Income and Other Nonbusiness Taxes and Subsidies, includes inheritance and gift taxes (H24) |
Personal Income, Wealth, and Their Distributions (D31) | Personal Income, Wealth, and Their Distributions (D31) |
Economics of Gender, Non-labor Discrimination (J16) | Economics of Gender, Non-labor Discrimination (J16) |
Household Saving, Personal Finance (D14) | |
Banks, Depository Institutions, Micro Finance Institutions, Mortgages (G21) | |
Health Behavior (I12) | |
General Welfare, Well-Being (I31) | |
Marriage, Marital Dissolution, Family Structure, Domestic Abuse (J12) |
“The Impact of the Earned Income Tax Credit on Household Finances” |
---|
Personal Income and Other Nonbusiness Taxes and Subsidies, includes inheritance and gift taxes (H24) |

How could you find more articles about the EITC impact on savings?
You could start with a narrow search:
"earned income tax credit"
AND su(d14) = 15 results
But this might be so narrow as to exclude some relevant research. How to expand?
All JEL codes starting with D are within the category Microeconomics.
G --> Financial Economics (e.g. G21)
H --> Public Economics (e.g. H24)
J --> Labor & Demographic Econ.
--> Will include only articles tagged "Household Saving, Personal Finance (D14)"
Search the entire JEL subcategory:
"earned income tax credit" AND su(d1*) = 27
Expand, but stay relatively focused - Try multiple JEL codes and adding a keyword:
"earned income tax credit" AND savings
AND su(d1* OR d3* OR h23 OR h24) = 38
