Urban parks are usually studied as discrete, green public open spaces. Less studied is how parks are geographically distributed from a ‘spatial logic’ point of view, i.e. how they ought to be geographically distributed across the urban landscape. This paper evaluates the degree to which normative principles about park distribution are in evidence from the standpoint of three spatial goals: proximity, diversity and social need. Using Phoenix and Chicago as case studies, it offers an empirical example of how park distribution can be shown to conform (or not) to one or more distributive patterns. Descriptive measures show that Phoenix parks do not conform to any of these three distributional principles, while Chicago parks do somewhat better. In both cities, land uses surrounding parks heavily favour residential uses. In Phoenix, single-family homes are prioritized, making spatial distribution based on proximity, diversity or social need difficult. A strategy for acquiring a better spatial logic, within existing realities and constraints, is suggested.

Urban parks are community assets, providing people places to play and rest. Access to parks in urban environments promotes social equity and improves quality of life for surrounding neighborhoods. In this context, social equity is related to accessibility, i.e. the possibility of walking or biking from home to a public park, giving people who do not have access to a variety of entertainment an option that is a public good. This paper examines the spatial distribution of urban parks in the city of Curitiba, Brazil, and how it relates to the socio-economic conditions of surrounding neighborhoods. Curitiba is known for its urban parks; however, no systematic study has been conducted to verify which neighborhoods enjoy park access within walking distance and what the socio-economic differences are between the better and worse served neighborhoods. In addition, we investigate if access to green open space has improved between the last two decennial census, a period marked by unprecedented socio-economic affluence in Brazil. Research questions, to be addressed using spatial analysis, focus on equitable distribution, and spatial evolution of parks and social equity. Variables include measurable walking distances from census tracts to parks, income data from the 2000 and 2010 Brazilian decennial censuses, and qualitative data of urban parks in Curitiba. Findings offer recommendations for future implementation of additional parks in Curitiba so that all areas of the city have adequate green open space and all citizens have equal access to recreation and leisure opportunities.
We study the link between self-employment and some salient aspects of entrepreneurship – namely business creation and innovation – in urban and rural labour markets. In order to do so, we combine indi- vidual and firm-level data for Britain aggregated at the Travel-to-Work Area level. We find that a higher incidence of self-employment positively and strongly correlates with business creation and innovation in urban areas, but not in rural areas. We also document that more rural than urban workers become self- employed in areas with comparably poor labour market opportunities, although this heterogeneity is not evident when focussing on entrepreneurship. Finally, we show that the misalignment between self- employment and our proxies for entrepreneurship in rural areas disappears once we account for local labour market conditions. Our results suggest that self-employment, business creation and innovation are well lined-up in urban areas because they capture the same economic phenomenon – namely, gen- uine entrepreneurship. This is not the case for rural areas.
