Genetic Algorithms : A Tool for Optimization in Econometrics - Basic Concept and an Example for Empirical Applications

Czarnitzki, Dirk; Doherr, Thorsten - 2008

This paper discusses a tool for optimization of econometric models based on genetic algorithms. First, we briefly describe the concept of this optimization technique. Then, we explain the design of a specifically developed algorithm and apply it to a difficult econometric problem, the...

Taming the Curse of Dimensionality : Quantitative Economics with Deep Learning

Fernández-Villaverde, Jesús; Nuño, Galo; Perla, Jesse - National Bureau of Economic Research - 2024

We argue that deep learning provides a promising avenue for taming the curse of dimensionality in quantitative economics. We begin by exploring the unique challenges posed by solving dynamic equilibrium models, especially the feedback loop between individual agents' decisions and the aggregate...

Firm-level investment under imperfect capital markets in Ukraine

Shcherbakov, Oleksandr - 2019

This paper develops and estimates a model of firm-level fixed capital investment when firms face borrowing constraints. Dynamically optimal investment functions are derived for the firms with and without financial constraints. These policy functions are then used to construct the likelihood of...

Should central banks worry about nonlinearities of their large-scale macroeconomic models?

Lepetyuk, Vadym; Maliar, Lilia; Maliar, Serguei - 2017

How wrong could policymakers be when using linearized solutions to their macroeconomic models instead of nonlinear global solutions? This question became of much practical interest during the Great Recession and the recent zero lower bound crisis. We assess the importance of nonlinearities in a...

A review of heuristic optimization methods in econometrics

Gilli, Manfred; Winker, Peter - 2008

Estimation and modelling problems as they arise in many fields often turn out to be intractable by standard numerical methods. One way to deal with such a situation consists in simplifying models and procedures. However, the solutions to these simplified problems might not be satisfying. A...

Pricing and Hedging of Asian Options : Quasi-Explicit Solutions via Malliavin Calculus

Yang, Zhaojun - 2013

We use Malliavin calculus and the Clark-Ocone formula to derive the hedging strategy of an arithmetic Asian Call option in general terms. Furthermore we derive an expression for the density of the integral over time of a geometric Brownian motion, which allows us to express hedging strategy and...
