主题：量化空间模型讲座
主讲人：David Krisztian Nagy
时间：2025年5月7-10日（周三到周六）
地点：威尼斯欢迎你welcome
语言：英语
参与方式：报名参与（详情见正文）
活动简介：
本活动包括四个系列讲座，即量化空间模型的基本设定、编程与模型应用、市场潜能与量化模型、动态量化空间模型。本讲座不仅讲授量化空间模型的建模方法，还将讲解如何利用Matlab做反事实模拟，旨在使参加者可以理解量化空间模型的基本理论，并能在自己的研究中运用量化空间模型。
讲座提纲
Lecture 1: Why does space matter? Increasing returns, transport costs and the geography of economic activity
Motivation: The high spatial concentration of economic activity
Increasing returns and transport costs lead to agglomeration
A simple quantitative spatial model: Chapter 3 in Redding (JIE, 2016)
Lecture 2: Quantitative illustration
Taking the Redding (2016) model to the data: data requirements, parameters
Matlab coding: Inversion and counterfactual simulation of the Redding (2016) model; exact hat algebra
Lecture 3: The importance of market access
Simple and structural measures of market access
Empirical evidence on the importance of market access: Redding and Sturm (AER, 2008)
Market access as a tool to evaluate transport infrastructure improvements: Donaldson and Hornbeck (QJE, 2016)
Matlab coding: Market access in the Redding (2016) model
Lecture 4: Dynamic spatial economics
Dynamic reallocation of labor after a spatial shock: Caliendo, Dvorkin and Parro (Econometrica, 2019)
Dynamic hat algebra
Matlab coding: Dynamic hat algebra, shooting algorithm
