Does new information technology change commuting behavior?

Our paper Does new information technology change commuting behavior written together with Sergejs Gubins and Jos van Ommeren is accepted in the Annals of Regional Science. It turned out to be nice paper with an interesting main message: commuting in total did not change under the advent of ICT. Our identification is interesting, albeit that it hinges upon a very strong idenfitication assumption. Apart from ICT trend in change of commuting do not differ amongst sector-job combinations.

Valuation of Ethnic Diversity: Heterogeneous Effects in an Integrated Labor and Housing Market

Our paper Valuation of Ethnic Diversity: Heterogeneous Effects in an Integrated Labor and Housing Market written together with Jessie Bakens is accepted in the Journal of Economic Geopraphy. Jessie and I worked quite hard on this and I am glad that we got the results. The abstract reads as follows: >We estimate the heterogeneous impact of the scale, composition and consumer good-effect of ethnic diversity on individuals' job and residential location.

Barriers of Culture, Networks, and Language

A new pubication is out in REGION with Zhiling Wang and Peter Nijkamp titled Barriers of Culture, Networks, and Language. A direct link can be found here, with the following abstract: Abstract Along with the increasing pace of globalization, recent decades faced a dramatically increase in international migrant flows as well. Compared to the flows of trade, capital and knowledge, we observe that contemporaneous complex institutional differences, historical backgrounds, and individuals’ diverse socio-demographic characteristics make the migrant workers’ choice of destination arguably much more uncontrollable.

New Economic Geography model with R

New economic geography model with R Introduction Why some regions have more economic activiy than others depend on a variety of factors, including regions’ endowments, good policy and just sheer luck (oftentimes called path dependency). In the 1990s Paul Krugman constructed a model, the Core-Periphery model, that was able to model all these three elements. This model received quite some positive criticism (including a Nobel price), but still is rather complex in wielding it.

Migrating from Jekyll to Hugo

Introduction For quite some time I have been thinking about migrating my (very small) website to the Hugo platform. Mostly because I admire the information rich structure of Kieran Healy’s website and he converted already from Jekyll to Hugo a while ago. Because my website is indeed quite small, it does not suffer from Jekyll oftentimes being slow. However, I needed some additional features of my Jekyll site (e.g., converting bibtex to a reference list), which could not automatically be rendered by Github which is my choice of deployment.

Sortingmod: an R-package for sorting models

Overview sortingmod is a package for estimating the sorting model - a discrete choice model which explains the location decision of heterogeneous individuals over a set of alternative locations. The model is developed by Bayer et al. (2004) following the work of Berry et al. (1995). It relies on the assumptions that individuals choose a location that maximizes their utility, and that heterogeneous individuals with different characteristics have different preferences, and different valuation for location characteristics.

Choosing statistical software packages for education in the social sciences

Introduction: the empirical workflow Econometrics is much easier without the data—Marno Verbeek The quote above does not only apply to economics and econometrics, but to all of the social sciences in general. Empirical research—that is, dealing with data in all its forms—requires a rigorous approach, even more so, with the increasing emphasis on openness and reproducibility of all kinds of scientific research. Therefore, it is strange that in academic education there is not much guidance in choosing which research tools to use and in the philosophy behing choosing an efficient and reproducable workflow.

A lines map of building height in Amsterdam

Introduction I just came across this wonderfull post on https://www.r-bloggers.com http://spatial.ly/2017/04/population-lines-how-and-why-i-created-it/ called Population Lines: How and Why I Created it) by James Cheshire. It allows for wonderfull (and artistic) maps constructed by only varations in height of horizontal lines. One might wonder how useful they are, but they sure are beautiful as one can see below in the population lines map of Europe. Population lines map of Europe (source http://blog.

A Heatmap of the Robustness of Determinants of European City growth

Introduction Understanding what makes a city tick (e.g., the determinants that makes cities succesful in employment of economic growth) is vital for both policy makers and (regional) economists. Indeed, local policy makers usually want to know what they can contribute to the performance of their city or region. If policy makers can at all influence the performance, then most likely instruments vary between cities and regions. What is good for one city is not necessarily good for another.

Social Interaction and Crime

Social Interaction and Crime: An Investigation Using Individual Offender Data in Dutch Neighborhoods conditionally accepted in RESTAT Just heard that my paper Social Interactions and Crime Revisited: An Investigation Using Individual Offender Data in Dutch Neighborhoods written together with Wim Bernasco, Jan Rouwendal and Wouter Steenbeek is conditionally accepted in the Review of Economics and Statistics. Im am rather happy with this result; especially given the fact that we have worked on this for more than 5 years (not consecutively but still).
