Promotion Zhiling Wang

Promotion and defense ceremony of Zhiling Wang

My second Ph.D. student got her Ph.D. degree! With an almost flawless defense and a very good Ph.D. thesis Zhiling obviously deserves all the credit. However, I could not resist to post this picture. Somehow, I resemble Jose Mourinho, the angry looking football trainer.

Drawing Edgeworth boxes with LaTeX

Factor mobility and welfare For educational purposes we teach in the second year’s course regional and urban economics students the Edgeworth-Bowley box. At first sight the concept is quite simple, but because there are restrictions for the total amount of both labour and capital in both regions or countries, the intuition behind the model and especially the drawing of the box is rather complex. Therefore, I once wrote a straightforward but elaborate LaTeX script invoking the Tikz package.

Krugman's Increasing Returns and Economic Geography

Drawing the diagram of a stylized version of Krugman’s Increasing Returns and Economic Geography For educational purposes we teach in the second year’s course regional and urban economics a simplified version of Krugman’s model in his paper titled Increasing Returns and Economic Geography. The model we have adopted goes as follows: We consider a simplified economy with two regions and 1 (million) workers ( $L=1$ ) in total. Region 1 is inhabited by 100,000 farmers (bound to their land so immobile), while in Region 2 there are 200,000 farmers.

Cultural diversity versus cultural distance

With Zhiling Wang and Peter Nijkamp This study analyses the impact of cultural composition on regional attractiveness from the perspective of international migrant sorting behavior on a European regional NUTS1 level. We use an attitudinal survey to quantify cultural distances between natives and immigrants in the region concerned, and estimate the migrants’ varying preferences for both cultural diversity and cultural distance. To account for regional unobserved heterogeneity, our econometric analysis employs artificial instrumental variables, as developed by Bayer et al.

WooW-II: Workshop on open Workflows

With Daniel Arribas-Bel This resource describes WooW-II, a two-day workshop on open workflows for quantitative social scientists. The workshop is broken down in five main parts, where each of them typically consists of an introductionary tutorial and a hands-on assignment. The specific tools discussed in this workshop are Markdown, Pandoc, Git, Github, R, and Rstudio, but the theoretical approach applies to a wider range of tools (e.g., LaTeX, and Python).

Stedelijke voorzieningen en bevolking: wie woont waar en waarom?

Waarom zijn sommige steden aantrekkelijker dan andere steden? Eén van de belangrijke en boeiende onderzoeksvragen in de ruimtelijke economie betreft het verklaren waarom sommige steden aantrekkelijker zijn voor huishoudens en bedrijven dan andere. Als maatstaven voor aantrekkelijkheid worden vaak lonen en huizenprijzen genomen en deze verschillen inderdaad significant tussen gemeenten in Nederland. Zoals bijvoorbeeld de publicatie Stad en Land (De Groot e.a., 2010) al liet zien, kunnen de verschillen tussen grondprijzen in Nederland oplopen tot een factor 200 per vierkante meter kunnen jaarlonen verschillen tot 7 procent voor een zelfde soort baan.
