Estimation of general linear and non-linear equations, nested and non-nesting models and hypothesis testing; estimation with panel data, systems of equations and applications in microeconomics and macroeconomics; dummy variables and spline functions; limited dependent variables, selectivity bias and applications in economics; time series econometrics with applications in macroeconomics. Emphasis on the practical applications of econometric theory as developed in other courses; specific problems in the specification, estimation and testing of various microeconomic theories of demand, production, and labour as well as the macroeconomic relations of monetary, inflation, and unemployment theory.
