Using Economics Software (Stata, R)

Stata and R are statistical software packages widely used for economic analysis, data management, and visualization. These tools enable economists to test hypotheses, model trends, and interpret complex datasets efficiently. For online economics students, proficiency in Stata or R is critical for conducting research, completing coursework, and preparing for careers requiring data-driven decision-making. This resource explains how both programs function, their comparative strengths, and how to apply them effectively in academic and professional contexts.

You’ll learn the core features of Stata and R, including data manipulation, regression analysis, and graphical output generation. The article compares their interfaces, scripting languages, and community support ecosystems to help you choose the right tool for specific tasks. Practical examples demonstrate how to clean datasets, run econometric models, and present results clearly—skills directly applicable to thesis work or policy analysis.

Online economics education relies heavily on software-based projects due to its focus on remote collaboration and independent study. Stata’s menu-driven options simplify initial learning, while R’s open-source flexibility supports advanced customization. Both integrate with platforms like LaTeX and GitHub, streamlining workflow management for distributed teams. Understanding these tools helps you handle real-world data challenges, from replicating published studies to automating repetitive tasks.

This resource prioritizes actionable insights over abstract theory. You’ll gain strategies for troubleshooting errors, optimizing code efficiency, and maintaining reproducibility—key competencies for academic research and roles in government, consulting, or tech. Whether analyzing labor market trends or forecasting macroeconomic indicators, Stata and R provide the technical foundation to execute rigorous, scalable economic analysis.

Key Differences Between Stata and R

Choosing between Stata and R depends on your workflow preferences, budget, and research goals. Both tools handle statistical analysis and econometrics, but their approaches differ significantly in structure, cost, and adaptability. Below we break down their core distinctions.

Strengths of Stata: Integrated Workflows and Academic Prevalence

Stata prioritizes simplicity for standardized economic analysis. Its menu-driven interface and built-in commands let you run regressions, manage datasets, and create publication-ready graphs without programming. You’ll find this useful if you prefer clicking through dropdown menus or using intuitive commands like regress for linear models or xtreg for panel data.

Stata’s tightly integrated environment ensures consistency across data manipulation, analysis, and visualization. For example, after estimating a model with ivregress, you can directly test for heteroskedasticity using estat hettest without importing results to another tool. This reduces errors and speeds up repetitive tasks.

Academic economists overwhelmingly use Stata. Most graduate programs and research institutions teach it as the default for applied microeconomics, labor studies, and development economics. Textbooks and published papers frequently include Stata code examples, making replication easier. Prebuilt modules for complex methods like difference-in-differences, instrumental variables, and survival analysis mean you spend less time coding from scratch.

However, Stata requires paid licenses, which range from $50-$250/year for students to $1,000+/year for professional plans. Updates occur every 2-3 years, so newer methods (e.g., machine learning techniques) arrive slower than in R.

Advantages of R: Open-Source Flexibility and Package Ecosystem

R is free, open-source, and infinitely customizable. You can modify existing functions, write custom packages, or integrate with Python/C++ for high-performance computing. This makes it ideal for non-standard analyses, such as agent-based modeling, network analysis, or Bayesian econometrics.

R’s package ecosystem provides tools for nearly any task. The Comprehensive R Archive Network (CRAN) hosts over 18,000 packages, including econometrics-specific libraries like plm (panel data), ivreg (instrumental variables), and broom (tidy model outputs). The tidyverse suite streamlines data wrangling with readable syntax:
r data %>% filter(year > 2010) %>% group_by(country) %>% summarize(gdp_mean = mean(gdp))

Reproducibility is stronger in R. Script-based workflows let you automate entire analyses, reducing manual errors. Version control via Git integrates seamlessly with RStudio, a popular IDE. For big data, packages like data.table and arrow handle datasets larger than Stata’s 2-billion-row limit.

The trade-off is a steeper learning curve. R expects coding proficiency, and debugging package conflicts can frustrate new users. While Stata offers dedicated support, R relies on community forums like Stack Overflow.

Industry Adoption Rates and 2023 Usage Trends

Stata dominates academic economics and policy research. Government agencies, think tanks, and universities favor it for standardized analyses with strict deadlines. Its prevalence in health economics and program evaluation ensures job candidates with Stata skills remain in demand for research assistant and analyst roles.

R leads in data science and tech-driven fields. Tech companies, fintech startups, and central banks use R for machine learning, data visualization, and handling unconventional data types (e.g., text, geospatial). Economists working with massive datasets or open-source collaborations increasingly prefer R for its scalability and cost efficiency.

In 2023, three trends stand out:

R gains ground in academia as institutions prioritize computational skills. Graduate programs now often teach both tools, with R favored for metrics like causal forests or structural estimation.
Stata adopts machine learning features, like its lasso package, to retain users needing quick implementations of modern methods.
Hybrid workflows emerge. Researchers clean data in Stata for simplicity, then export to R for advanced visualizations using ggplot2 or interactive dashboards with Shiny.

Your choice depends on context. Stata offers efficiency for routine tasks, while R provides limitless flexibility for cutting-edge work.

Setting Up and Learning Core Functions

This section provides direct instructions for installing Stata and R, understanding their basic workflows, and accessing critical resources. Focus on practical steps to start analyzing economic data efficiently.

System Requirements and License Management

Stata requires a 64-bit processor and operates on Windows, macOS, or Linux. Minimum RAM is 4GB (8GB recommended for large datasets). Installation involves downloading the installer from the official site and entering a license key during setup. Licenses are device-specific and may require annual renewal for subscriptions. Academic pricing is typically available.

R is free and open-source, compatible with all major operating systems. It runs efficiently on systems with 2GB RAM, though 4GB or more improves performance with complex models. Install the base version from the Comprehensive R Archive Network (CRAN). For a more user-friendly experience, install RStudio as your integrated development environment (IDE).

Key differences:

Stata licenses restrict simultaneous use across devices unless purchasing a multi-user plan.
R has no licensing costs, but some third-party packages may have individual use agreements.
Both require regular updates for security patches and new features. Check Stata updates via update all and R updates by reinstalling from CRAN or using install.packages("installr") on Windows.

Basic Syntax Comparison: Stata Commands vs. R Scripts

Stata uses command-line execution with optional do-files for scripting. R relies on scripts (R files) executed in the console or IDE.

Loading Data

Stata: use "filename.dta"
R: data <- read.csv("filename.csv") or load("filename.RData")

Summary Statistics

Stata: summarize variable1 variable2
R: summary(data$variable1)

Linear Regression

Stata: regress y x1 x2
R: model <- lm(y ~ x1 + x2, data = dataset) then summary(model)

Key Syntax Differences

Stata commands are standalone; R requires object assignment (<-) and explicit function calls.
Stata variable references use spaces (var1 var2); R uses formulas with operators (var1 + var2).
R functions require parentheses (function()); Stata commands do not.

Accessing Built-In Datasets and Help Documentation

Both platforms include datasets for practice and testing.

Stata

Load built-in data: sysuse auto.dta
List datasets: sysuse dir
Access help: Type help regress in the command window or press F1. Use search followed by a keyword to find related commands.

Load datasets from base R: data(mtcars)
View available datasets: data()
Get help: Type ?lm or help("lm") in the console. For package-specific help, load the package first with library(packagename).

Troubleshooting Tips

Stata error codes often include links to relevant help sections.
R error messages may require searching online forums using exact wording.
Both platforms maintain extensive official documentation for functions and best practices.

For ongoing learning, practice modifying existing code examples from documentation to suit your data. Start with small datasets to test commands before scaling to larger analyses.

Data Management Techniques

Effective data management forms the foundation of economic analysis. Whether working with survey data, financial records, or macroeconomic indicators, you need reliable methods to import, clean, and structure datasets. This section covers three core skills: handling diverse data sources, transforming variables, and preparing panel data for time-series analysis.

Handling CSV, Excel, and API Data Sources

Most economic datasets come in CSV, Excel, or API formats. Stata and R handle these differently:

CSV Files:
- In Stata: Use import delimited "filename.csv" for quick imports. Add clear to replace existing data.
- In R: Use read.csv("filename.csv") or data.table::fread("filename.csv") for faster processing of large files.
Excel Files:
- In Stata: Use import excel "filename.xlsx", specifying sheets with sheet("Sheet1").
- In R: Use readxl::read_excel("filename.xlsx", sheet = 1) for .xlsx files.
API Sources:
- In Stata: Use the copy command with URLs (copy "https://api.example/data" data.json, replace) or install the libjson plugin.
- In R: Use httr::GET() to retrieve data, then parse JSON responses with jsonlite::fromJSON().

Key considerations:

Check encoding issues in CSV files using encoding(utf-8) in Stata or encoding = "UTF-8" in R.
Use R’s janitor::clean_names() or Stata’s rename _all, lower to standardize column names.
For large datasets (>1GB), use R’s data.table or Stata’s set max_memory to optimize performance.

Variable Transformation and Missing Value Treatment

Economic data often requires recoding variables and addressing gaps.

Variable transformations:

Create logarithmic variables in Stata with gen ln_gdp = ln(gdp) or in R with data$ln_gdp <- log(data$gdp).
Categorize continuous variables using recode in Stata or cut() in R.

Handling missing values:

Identify missingness with Stata’s misstable summarize or R’s is.na(data).
Use mvdecode in Stata or na.omit() in R to delete rows with missing values. For panel data, consider xtdrop in Stata to remove incomplete time-series.
Impute missing values using:
- Stata: mi impute regress
- R: mice::mice()

Best practices:

Always document missing value thresholds (e.g., “dropped variables with >30% missingness”).
Use assert in Stata or stopifnot() in R to validate data integrity post-transformation.

Merging Panel Data and Time-Series Adjustments

Panel data requires merging datasets and adjusting for temporal patterns.

Merging datasets:

In Stata: Use merge 1:1 country year to combine data by unique identifiers.
In R: Use dplyr::left_join(df1, df2, by = c("country", "year")).

Time-series adjustments:

Declare panel structure in Stata with xtset country year. In R, use plm::pdata.frame(data, index = c("country", "year")).
Calculate lags:
- Stata: gen gdp_lag = L.gdp
- R: dplyr::lag(data$gdp)
Handle seasonality with tssmooth in Stata or forecast::ma() in R.

Critical checks:

Confirm no duplicate observations exist using duplicates report in Stata or duplicated() in R.
After merging, verify alignment with tsset in Stata or ts.plot() in R.
For unbalanced panels, use fillin in Stata or tidyr::complete() in R to insert missing time periods.

By mastering these techniques, you ensure your datasets are analysis-ready, reducing errors in downstream tasks like regression modeling or forecasting.

Statistical Analysis for Economic Models

This section provides direct implementation steps for core statistical methods used in economic research. You’ll learn to execute regression models, forecast economic indicators, and validate results using Stata and R. Code examples are designed for immediate application in online economics projects.

Linear Regression: Code Examples for Both Platforms

Linear regression forms the foundation of econometric analysis. Use ordinary least squares (OLS) to estimate relationships between variables and interpret coefficients as marginal effects.

Stata Example (Simple OLS):
stata regress gdp growth inflation, robust

regress runs OLS
gdp is the dependent variable
growth and inflation are predictors
robust specifies heteroskedasticity-consistent standard errors

R Example (Multiple Regression):
r model <- lm(gdp ~ growth + inflation + unemployment, data = econ_data) summary(model)

lm() fits the linear model
The formula gdp ~ ... defines the relationship
summary() displays coefficients, R-squared, and p-values

For diagnostics:

In Stata, use estat hettest for heteroskedasticity checks.
In R, use plot(model) to review residual plots.

Time-Series Analysis with ARIMA and VAR Models

Time-series analysis handles economic data indexed over time. ARIMA models predict univariate trends, while VAR models capture interdependencies between multiple time series.

ARIMA Implementation:
Stata:
stata arima gdp, arima(1,1,1) forecast create, replace foreast estimate

arima(1,1,1) specifies autoregressive, differencing, and moving average terms
forecast generates predictions

R:
r library(forecast) fit_arima <- arima(econ_data$gdp, order = c(1,1,1)) forecast(fit_arima, h = 12) # 12-period forecast

VAR Model Implementation:
Stata:
stata var gdp inflation unemployment, lags(1/4)

lags(1/4) includes lags 1 through 4

R:
r library(vars) var_model <- VAR(econ_data, p = 4, type = "const") predict(var_model, n.ahead = 10)

Instrumental Variable Estimation and Robustness Checks

Instrumental variables (IV) address endogeneity by using external instruments to isolate causal effects.

IV Regression Code:
Stata (2SLS):
stata ivregress 2sls gdp (growth = instrument), robust

(growth = instrument) specifies growth as endogenous and instrument as the IV

R:
r library(AER) iv_model <- ivreg(gdp ~ growth + inflation | inflation + instrument, data = econ_data) summary(iv_model)

Robustness Checks:

Test for weak instruments using first-stage F-statistics (Stata: estat firststage; R: check summary(iv_model) diagnostics).
Run alternative specifications by adding control variables or using different IVs.
Check overidentifying restrictions with Sargan-Hansen tests (Stata: estat overid; R: use ivreg::summary with J-test results).

For replication integrity:

In Stata, rerun models with vce(bootstrap) to compute bootstrapped standard errors.
In R, use the sandwich package to adjust standard errors for model misspecification.

Visualization and Reporting Results

Producing clear visualizations and polished reports transforms raw analysis into actionable insights. This section covers techniques to create publication-quality outputs in Stata and R, focusing on workflow efficiency and academic standards.

Customizing Graphs: Stata’s GUI vs. R’s ggplot2

Stata’s graphical user interface (GUI) provides immediate control over chart elements. After generating a basic plot with commands like scatter or line, you refine it using the Chart Editor. Adjust axis labels, colors, and legends through dropdown menus. For example:
twoway (scatter gdp year), title("GDP Growth")
Right-click the graph to modify titles, gridlines, or data point symbols. The GUI is ideal for quick adjustments without memorizing syntax.

R’s ggplot2 uses a layered approach to customization. Start with ggplot() and add components like geom_line() or theme_minimal(). Each layer modifies specific aspects:
ggplot(data, aes(x=year, y=gdp)) + geom_line(color="#2c7fb8") + labs(title="GDP Growth") + theme(axis.text.x = element_text(angle=45))
To change fonts or background colors, edit theme() parameters. While ggplot2 requires memorizing syntax, it offers finer control over aesthetics than Stata’s GUI. For complex visualizations (e.g., faceted plots or animated charts), ggplot2 scales more effectively.

Key differences:

Stata suits iterative editing through point-and-click, but reproducibility suffers if changes aren’t saved as code.
ggplot2 demands upfront coding but ensures full replicability. Use ggsave() to export plots in precise dimensions (e.g., ggsave("plot.png", width=8, height=6, dpi=300)).

Automated Report Generation with LaTeX Integration

Both Stata and R integrate with LaTeX to automate results reporting:

Stata: Use esttab or estout to export regression tables directly into .tex files:
eststo model1: reg y x1 x2 esttab model1 using "results.tex", replace label
Combine this with LaTeX’s \input{results.tex} to embed tables. For dynamic text, create .do files that generate updated outputs when rerun.
R: The knitr package combines R code, results, and prose into a single document. Write .Rnw files with LaTeX structure and embed code chunks:
<<echo=FALSE>>= summary(lm(y ~ x1 + x2, data)) @
Compile with knit() to produce PDFs. Use stargazer or xtable for LaTeX-formatted tables.

Automation reduces manual errors when updating figures or statistics. Both languages support batch processing: run scripts to regenerate all outputs after data changes.

Exporting Tables for Academic Papers and Presentations

Academic papers require tables in LaTeX or Word. In Stata:

Use esttab with the tex or docx option:
esttab model1 using "table.docx", replace wide label
Adjust decimal places and significance stars using b(%9.3f) or star(* 0.1 ** 0.05) in esttab.

In R:

The stargazer package exports regression results:
stargazer(model1, type="latex", out="table.tex")
For non-regression tables, use kableExtra to format data frames:
kable(data, "latex", booktabs=TRUE) %>% kable_styling(latex_options="striped")

Presentations often need Excel or PowerPoint outputs. Stata’s putexcel creates formatted Excel sheets:
putexcel set "results.xlsx", replace putexcel A1 = "Coefficient" B1 = matrix(results), colnames
In R, use writexl for Excel files or officer for PowerPoint:
library(writexl) write_xlsx(data, "table.xlsx")

Always verify journal guidelines for font sizes, margins, and file formats. Test exports early to avoid last-minute formatting issues.

Practical Application: Analyzing Labor Market Data

This section demonstrates how to analyze unemployment data using Stata and R. You’ll process raw labor market statistics, run panel data models, and compare results across both tools.

Importing BLS Data and Defining Variables

Begin by acquiring unemployment data from the Bureau of Labor Statistics (BLS). Most datasets are distributed in CSV or Excel formats.

In Stata:

Use import delimited to load CSV files:
stata import delimited "unemployment_data.csv", clear
Convert date strings to numeric formats with date():
stata gen date_numeric = date(date_string, "YMD") format date_numeric %td
Declare panel structure with xtset:
stata xtset state_fips_code date_numeric

In R:

Import data using read.csv:
r unemployment <- read.csv("unemployment_data.csv")
Convert dates with lubridate:
r library(lubridate) unemployment$date_numeric <- ymd(unemployment$date_string)
Set panel structure with plm:
r library(plm) pdata <- pdata.frame(unemployment, index = c("state_fips_code", "date_numeric"))

Define key variables identically in both tools:

Dependent variable: unemployment_rate
Independent variables: gdp_growth, inflation_rate, job_openings
Grouping variables: state_fips_code, date_numeric

Running Fixed-Effects Models in Stata and R

Fixed-effects models control for time-invariant differences between states.

Stata Implementation:
Use xtreg with the fe option:
stata xtreg unemployment_rate gdp_growth inflation_rate job_openings, fe

fe specifies fixed effects
Output includes state-specific intercepts and coefficients for predictors

R Implementation:
Use plm with model = "within":
r model_fe <- plm(unemployment_rate ~ gdp_growth + inflation_rate + job_openings, data = pdata, model = "within") summary(model_fe)

model = "within" replicates Stata’s fixed-effects approach
Use summary() to view coefficient estimates and standard errors

Key differences to anticipate:

Stata automatically displays F-tests for overall model significance
R’s plm requires explicit calls to summary() for detailed diagnostics
Both tools will produce nearly identical coefficient values if data preparation is consistent

Comparing Output Interpretation and Visualization

After running models, interpret coefficients and visualize trends.

Interpreting Results:
A typical fixed-effects output includes:

Negative coefficient for gdp_growth (higher GDP growth correlates with lower unemployment)
Positive coefficient for job_openings (more vacancies reduce unemployment)
State-specific effects absorbed by the model

In Stata, focus on:

_b[gdp_growth] for point estimates
P>|t| values for statistical significance

In R, extract coefficients with:
r coef(model_fe)

Visualizing Trends:
Create state-level unemployment rate charts.

Stata Visualization:
stata twoway (line unemployment_rate date_numeric if state_fips_code == 06, legend(label(1 "California")))

R Visualization:
r library(ggplot2) ggplot(unemployment, aes(x = date_numeric, y = unemployment_rate)) + geom_line() + facet_wrap(~state_fips_code)

Critical consistency checks:

Verify date formats match in both tools
Confirm panel structures use identical grouping variables
Ensure categorical variables (e.g., state codes) are factor types in R or labeled numeric codes in Stata
Cross-validate key coefficients between Stata’s xtreg and R’s plm outputs

Decision points for analysis:

Use Stata for streamlined model diagnostics and one-line hypothesis testing
Use R for customized visualizations or complex data transformations prior to modeling
Both tools can export results to LaTeX or HTML formats for academic publishing

Key Takeaways

Here's what you need to remember about economics software choices:

Stata works best if you prioritize standardized academic workflows (used in 30% of economics research) with built-in econometric tools for quick replication of common methods
R saves costs and scales better for custom projects using its 15,000+ free packages, but requires more coding skill to combine tools effectively
Prepare for different approaches: Stata simplifies data merging through menus, while R uses code-driven tools like dplyr. Visualization in Stata is point-and-click versus R’s ggplot2 code-based system

Next steps: Choose Stata for routine academic tasks requiring peer validation, or R for flexible, budget-friendly analysis needing unique methods.
