In this paper, we tackle the issue of locating a public facility which provides a public good in a closed and populated territory. This facility generates differentiated benefits to neighborhoods depending on their distance from it. In the case of a Nimby facility, the smaller is the distance,...

In the past few years sustainability and sustainable development have become important concepts widespread over the world. There is no agreement on a common definition of sustainability, but there is a general need to measure and assess sustainability in different geographical and spatial...

This paper offers a new theoretical approach to urban squatting, reflecting the view that squatters and formal residents compete for land within a city. The key implication of this view is that squatters squeeze" the formal market, raising the price paid by formal residents. The squatter...

The objective of this paper is to show how the same market failures that contribute to urban sprawl also contribute to urban blight. The paper develops a simple dynamic model in which new suburban and older central-city properties compete for mobile residents. The level of housing services...

The turbojet engine operates on the ideal Brayton cycle (gas turbine) and consists of six main parts: diffusers, compressors, combustion chambers, turbines, afterburners and nozzles. Using computer code writing in MATLAB software environment, exergy analysis on all selected turbojet engine...

This paper studies the spatial structure of firms, both theoretically and empirically. Two new facts in Danish register data motivate the analysis. First, firms have become more fragmented over time. Second, headquarters (HQ) establishments have become more manager intensive, despite a...

We provide a new framework for using text as data in empirical models. The framework identifies salient information in unstructured text that can control for multidimensional heterogeneity among assets. We demonstrate the efficacy of the framework by re-examining principal-agent problems in...

Street networks may be planned according to clear organizing principles or they may evolve organically through accretion, but their configurations and orientations help define a city's spatial logic and order. Measures of entropy reveal a city's streets' order and disorder. Past studies have...

Children from poor families achieve more academically if they are enrolled in schools that are socioeconomically integrated, but low-income students are increasingly attending schools characterized by high concentrations of poverty. Providing more housing opportunities for low-income families...

The central prediction of the monocentric city model is that real estate prices, density of development, population density, and land rent decline with the distance from urban center. The spatial pattern follows a negative exponential under the conditions derived by Brueckner (1982) and McDonald...
