Computer Aided Design (CAD) technology plays a key role in today's advanced manufacturing environment. To reduce the time to market, achieve zero defect quality the first time, and use available production and logistics resources effectively, product and design process knowledge covering the whole product life-cycle must be used throughout product design. Once generated, this intensive design knowledge should be made available to later life-cycle activities. Due to the increasing concern about global environmental issues and rapidly changing economical situation worldwide, design must exhibit high performance not only in quality and productivity, but also in life-cycle issues, including exte...
Under capital tax competition, surprisingly, Ogawa and Wildasin (2009) find that uncoordinated policymaking leads to a first-best outcome even in the presence of transboundary pollution. However, I show that if the level of environmental regulation is endogenized, the regulation level becomes too loose compared with the optimum (“race to the bottom”). Thus, despite the efficiency result of Ogawa and Wildasin (2009), efforts to achieve international environmental policy coordination are needed. I then examine the dependence of this result on the level of decisive voter's capital endowment. The regulation is inefficiently loose in many cases, but it can be too strict if the decisive voter'...
This paper studies the relative importance of history and expectations in the spatial economy through the atomic bombing of Hiroshima. Newly digitizing granular data on the distribution of economic activities within the city of Hiroshima, we first demonstrate the startling history-independence: the city's center strongly recovered only about five years after being destroyed. We present a dynamic urban economics model that incorporates both history and expectations, allowing us to quantify their relative importance in redevelopment. We find that expectations for rebuilding are self-fulfilling in that they provide a strong incentive to rebuild the city center despite its catastrophic history.
I document novel stylized facts on learning and its relationship with population density, using Japanese survey data that provide distinctively rich first-hand information about the frequency, purpose, subject, and method of off-the-job learning. First, people learn more frequently in denser cities. Second, people in denser cities are more likely to learn to gain new employment or cultivate themselves, while they are less likely to learn for their current job. Third, what people learn by which method is related to the local demand for skills and the local supply of learning opportunities. I discuss the implications of these findings for theory and evidence of urban agglomeration economies.
The AACR Annual Meeting highlights the best cancer science and medicine from institutions all over the world. Attendees are invited to stretch their boundaries, form collaborations, attend sessions outside their own areas of expertise, and learn how to apply exciting new concepts, tools, and techniques to their own research. Part A contains abstracts 1-3062 accepted for the 2017 meeting.
