Statistical Analysis of Economic Data ECON 333 (4)

ECON 333 offers an introduction to the use and interpretation of statistical analysis in the context of data typical of economic applications. Prerequisite: ECON 103 with a minimum grade of C- or ECON 113 with a minimum grade of A-; ECON 105 with a minimum grade of C- or ECON 115 with a minimum grade of A-; ECON 233 or BUS (or BUEC) 232 or STAT 270, MATH 157, all with a minimum grade of C-; 60 units. Students with a minimum grade of A- in ECON 233, BUS (or BUEC) 232 or STAT 270 can take ECON 333 after 30 units. Students seeking permission to enroll based on their ECON 233, BUS (or BUEC) 232 or STAT 270 grade must contact the undergraduate advisor in economics. Students with credit for BUEC 333 may not take this course for further credit. Quantitative.

Conduct statistical and/or quantitative analysis using a computer

• Incorporate nonlinearities, interactions and dummy variables in a linear regression model (I)
• Use a specialized statistical package (e.g., R, Stata) to read in simple data (I)
• Use a specialized statistical package to estimate a linear regression model (I)
• Manage data and code (D)

Relate causal inference, selection and endogeneity

• Distinguish between statistical and causal relationships (I)
• Identify and explain possible sources of bias in a given analysis (I)
• Use economics to identify the likely direction of bias in a given analysis (I)

#### Critically assess economic arguments, assumptions, and evidence

Critically evaluate assumptions in economic/econometric models

• Assess the validity/plausibility of the key assumptions in an econometric model (I)
• Identify the key statistical assumptions in a linear regression analysis (I)

#### Use oral, written, and graphical methods to communicate economic insights

Present economic arguments by means of graphs, charts and tables

• Construct and interpret a bar chart (I)
