Collaborative knowledge exchange promotes innovation
Tomoya Mori, Jonathan Newton, Shosei Sakaguchi
Considering collaborative patent development, we provide micro-level evidence for innovation through exchanges of differentiated knowledge. Knowledge embodied in a patent is proxie…
Origin of power laws and their spatial fractal structure for city-size distributions
Tomoya Mori, Takashi Akamatsu, Yuki Takayama +1
City-size distributions follow an approximate power law in various countries despite high volatility in relative city sizes over time. Our empirical evidence for the United States…
Tree Edit Distance with Variables. Measuring the Similarity between Mathematical Formulas
Tatsuya Akutsu, Tomoya Mori, Naotoshi Nakamura +3
In this article, we propose tree edit distance with variables, which is an extension of the tree edit distance to handle trees with variables and has a potential application to mea…
Cities in a world of diminishing transport costs
Tomoya Mori, Minoru Osawa
Economic activities favor mutual geographical proximity and concentrate spatially to form cities. In a world of diminishing transport costs, however, the advantage of physical prox…
Spatial scale of agglomeration and dispersion: Number, spacing, and the spatial extent of cities
Takashi Akamatsu, Tomoya Mori, Minoru Osawa +1
How does transport cost affect the spatial organization of economic activities? This study develops a theoretical framework that distinguishes between two types of dispersion force…
Spatial pattern and city size distribution
Tomoya Mori
Many large cities are found at locations with certain first nature advantages. Yet, those exogenous locational features may not be the most potent forces governing the spatial patt…
Creation of knowledge through exchanges of knowledge: Evidence from Japanese patent data
Tomoya Mori, Shosei Sakaguchi
This study shows evidence for collaborative knowledge creation among individual researchers through direct exchanges of their mutual differentiated knowledge. Using patent applicat…
Cities and space: Common power laws and spatial fractal structures
Tomoya Mori, Tony E. Smith, Wen-Tai Hsu
City size distributions are known to be well approximated by power laws across a wide range of countries. But such distributions are also meaningful at other spatial scales, such a…
