For advanced economies, it is a well-established stylized fact that large cities are relatively skill abundant. emerging markets, like China, this relationship less well established. We show, using recently developed tests, also in China higher skills sort into larger locations. This sorting process consistent with the comparative advantage of cities. identify two types spatial units (Core-Citi...

Bicycling accounted for an average of 1.2% of work trips in Canada in 2001, but with considerable variation by province and metropolitan area. In this study, we chose six Canadian cities for detailed analysis of their cycling trends and policies: Montreal and Quebec City in Quebec; Ottawa and Toronto in Ontario; and Vancouver and Victoria in British Columbia. All of these cities have made impre...

Article history: Received 26 July 2009 Available online 13 August 2010 This article uses new data to analyze the impact on Southeast Asian urbanization of globalization and industrialization in the world economy's core countries between the 1870s and World War II. Dramatic falls in transport costs and free trade, enforced, if necessary, by colonial rule, combined to open vast frontier areas thr...

Have you ever thrown an apple core or an orange peel out of the car window? Is this littering? What happens if it lands on the pavement? Is it the same as if it lands in a patch of soil on the side of the road? Apple cores, orange peels, leaves, and other plant materials are made up of complex carbon compounds, which get broken down over time into simpler forms of carbon in a process called dec...

Traveling salesman problems with revenues form a generalization of traveling salesman problems. Here, next to travel costs an explicit revenue is generated by visiting a city. We analyze routing problems with revenues, where a predetermined route on all cities determines the tours along subgroups. Corresponding routing games with revenues are analyzed. It is shown that these games have a nonemp...

Ecosystem services (ES) in cities and surrounding suburban areas are one of the major factors which guarantee quality of life. Most studies directly referring to urban ecosystem services are conducted on a local scale or for selected cities. There are few studies which focus on temporal changes of the provision of ecosystem services across a large number of cities. This paper analyzes selected ...

There is a need for a more integrated and flexible approach to core area urban redevelopment at a time when pressures to maximise economic returns from inner city land threaten to disrupt the livelihoods and established social networks of many urban poor communities. This paper draws upon the experiences of established planning and partnership redevelopment strategies (i.e. land sharing, land r...

There is much enthusiasm currently about the possibilities created by new and more extensive sources of data to better understand and manage cities. Here, I explore how big data can be useful in urban planning by formalizing the planning process as a general computational problem. I show that, under general conditions, new sources of data coordinated with urban policy can be applied following f...
