About Course

Quantitative Economics 2nd Year builds on foundational mathematical and statistical concepts to equip students with the analytical tools required to model, interpret, and solve real-world economic problems. The course focuses on the application of mathematics in economic theory, emphasizing both theoretical understanding and practical problem-solving skills.

Students are introduced to advanced mathematical techniques commonly used in economics, including matrix algebra, multivariable calculus, and differential equations. These tools are applied to key economic concepts such as optimization, equilibrium analysis, and dynamic economic systems.

A strong emphasis is placed on economic modelling, teaching students how to translate economic scenarios into mathematical form, analyze relationships between variables, and interpret results in an economic context. Topics may include constrained optimization, comparative statics, and the analysis of economic growth and stability models.

By the end of the course, students will be able to:

  • Apply mathematical methods to solve intermediate-level economic problems
  • Analyze and interpret economic models using quantitative techniques
  • Understand dynamic systems using differential and difference equations
  • Develop logical and analytical reasoning skills essential for econometrics and advanced economic analysis

This course is essential for students pursuing careers in economics, finance, data analysis, and econometrics, forming a critical bridge between theory and real-world quantitative application.

Unit 2: Matrix Inversion
This unit introduces matrix inversion and its use in solving systems of linear equations. Students learn how to compute inverses and apply them to find unique solutions efficiently in economic models.

Unit 3: Special Determinants & Matrices and their use in Economics
This unit introduces the Jacobian and Hessian matrices for analyzing multivariable functions. Students learn how to evaluate changes in economic models and use second-order conditions to determine optimal solutions.

Unit 4: Comparative Statics & Concave Programming
This chapter explores how optimal economic decisions change when key variables shift (comparative statics) and introduces concave programming for solving optimization problems. Students learn how to use conditions for optimality, apply Lagrange methods, and understand why concavity ensures stable and unique solutions.

Unit 5: Systems of Linear Equations
This chapter introduces systems of linear equations as a tool for modeling relationships between multiple economic variables. Students learn how to solve these systems using algebraic and matrix methods, and how to interpret solutions in an economic context, including equilibrium analysis and consistency of solutions.

Unit 6: Euclidean Spaces
This chapter introduces Euclidean spaces as the mathematical framework for analyzing vectors and multidimensional economic relationships. Students learn key concepts such as vectors, norms, distance, and inner products, which are used to measure and interpret economic variables in higher dimensions.

Unit 7: Linear Independence
This chapter explores linear independence and its role in determining whether a set of vectors provides unique and non-redundant information. Students learn how to test for independence, understand its connection to rank and dimension, and apply it to ensure meaningful solutions in economic models.
