This repository contains the code and data for a semester project in ECON5810 (Applied Econometrics). The project focuses on quantifying the impact of protectionist policies from 2018 to the present on the US semiconductor industry. The analysis covers various aspects such as employment, innovation, investment, and firm health.
The project is organized into several scripts and directories:
_01_dataprep.do: Prepares and cleans the dataset for analysis._02_sumstats.do: Generates summary statistics and correlation matrices._03_paneltests.do: Conducts various panel data tests including VIFs, autocorrelation, heteroscedasticity, and unit root tests._04_estimation.do: Runs different econometric models to estimate the impact of protectionist policies._05_robustchecks.do: Performs robustness checks including placebo tests, COVID-19 impact analysis, and sensitivity analysis.plots.R: Generates various plots to visualize the results of the analysis.
The data used in this project includes:
- Compustat data for firm-level financials and operations.
- CRSP data for firm age and security information.
- Federal Funds data for macroeconomic controls.
- Export data for industry-level shipment values.
The analysis focuses on the following key areas:
- Employment: Examines the impact on employment levels in the semiconductor industry.
- Innovation: Analyzes changes in R&D expenditure and intensity.
- Investment: Investigates capital expenditure trends.
- Firm Health: Assesses financial health through equity ratios and other financial metrics.
