Questions & Answers

Q: Why are the simplest applications of textual analysis the most successful?

The simplest applications of textual analysis have been successful because they focus on new data sources that provide valuable insights into economic concepts. Complex methods may not be well-suited to the specific questions economists ask.

Q: Why are economists uncomfortable with black box algorithms?

Economists are uncomfortable with black box algorithms because they prefer transparency and interpretability in their analysis. They want to be able to understand how the results were obtained and evaluate the validity of the methods.

Q: How can textual analysis be used to measure firm-level variables?

Textual analysis can be used to analyze firm-level data, such as earnings call transcripts, to generate variables that are otherwise difficult or impossible to measure. By analyzing the text, researchers can gain insights into firm behavior, risk perception, and other important economic concepts.

Q: What are some challenges in using textual analysis for economic research?

One challenge in using textual analysis is ensuring that the measured variables correspond to the actual economic concepts of interest. Additionally, cultural differences in language usage can affect the interpretation of text and the measurement of concepts.

Summary & Key Takeaways

• Textual analysis is increasingly being used in various fields of economics to measure economic concepts that are difficult to quantify.

• The simplest applications of textual analysis have been the most successful, focusing on new data sources rather than complex methods.

• Economists tend to be uncomfortable with black box algorithms and prefer simple methods that are transparent and easy to interpret.
