基于公司不进行正式研发投资的简要探讨

本文我们研究了正式的研发投资的频率。用实物期权和基于知识的观点去解释一个公司的知识资源是怎么影响该公司用于确定技术选择的研发投资频率。详细的说,我们得出一个公司若没有内部知识资源,很可能就总不投资研发;若有内外部知识资源,公司有时投资研发;但有内部知识资源而没有外部知识资源时,公司很可能总是投资研发。     

Congestion pricing of Canadian airports

Abstract Under congestion pricing, Canadian airports would annually save between $72 and $105 million. Social costs per landing and takeoff decrease about $300 at Toronto and Vancouver and $50 at Calgary and Montreal. Slot constraints fail to eliminate this airport congestion. Congestion prices are lower on average than existing weight‐based prices. Current airport capacity accommodates at least five more years of traffic growth before congestion reaches current levels. Substantial welfare gains occur even if dominant airlines already internalize their self‐imposed delays. This article calculates equilibrium congestion pricing schedules, traffic rates, queuing delays, layover times, and connection times by time of day.     

Information Shocks and the Dynamics of the Housing Market*

In this paper, we analyze housing‐market reactions to the release of previously unpublished information on school quality. Using high‐quality housing data, which precisely bracket the timing of the information shock, we investigate housing‐price dynamics within school‐catchment areas. We find a robust short‐term housing‐market reaction to the publication of school‐quality indicators, suggesting that this information was new to the households, and that households are willing to pay for better schools. The publication effect does not seem to be permanent as prices revert to pre‐publication levels after two to three months.     

Racial Harassment,Ethnic Concentration,and Economic Conditions*

In this paper, we analyse the association between the spatial concentration of ethnic minorities and racial harassment. Ethnic concentration relates to racial harassment through at least three channels: hostility in the attitudes of majority individuals that finds expression in harassment behaviour, the probability that minority individuals meet majority individuals, and the cost of expressing hostility aggressively. Thus, harassment cannot simply be modelled as a stronger form of hostility. Using unique data for Britain, we show that, in areas of higher local ethnic concentration, experience of harassment is lower, even though hostility on the side of the majority population is not.     

PRICING,CAPACITY, AND CONSTRUCTION BOUNDARY OF A CONGESTIBLE HIGHWAY WITH AN ELASTIC DEMAND: SOCIAL OPTIMUM,SECOND BEST,PRIVATIZATION, AND VERTICAL DISINTEGRATION*

This paper uses a spatial model to analyse first‐ and second‐best policies, impacts of privatization and vertical disintegration of a congestible highway with elastic demand. The paper also uses simulation methods to analyse the welfare cost of a uniform‐toll constraint. Results show, inter alia, that the social optimum requires the marginal cost of highway extension to be equal to the net consumer benefit at the boundary, while in the second‐best case the aggregate user cost must be measured in terms of the shadow price. In turn, a profit‐maximizing firm equates the marginal extension cost to the markup revenue at the boundary.     

“Development strategies at station areas in southwestern China: The case of Mianyang city”

This paper analyses the possibilities for implementing a TOD model around a railway station in Mianyang City, in southwestern China, through a Node-Place model to determine the potential for developing the areas around railway stations to foster a sustainable economic and urban development. For this purpose, the implementation of a TOD model means an interesting sustainable way for smart growth, whose successful implementation will strongly depend on the context, where the Growth Pole Theory is being implemented through the Western Development Strategy to strengthen the Chengdu-Chongqing Economic Zone. The Hukou system (household registration) and the current rapid urbanization and motorization trends are featuring the economic growth, creating inequities among urban population, informal settlements and problems in the accessibility of low-income residents. Therefore, not only does it lead to an analysis of the most important station areas in northeastern Sichuan Province but also of the socio-economic trends of one of the most underdeveloped regions of the country, yet with a high potential to be developed. Consequently, the real situation of the Northeast of Sichuan province is studied through fieldworks which complement the lack of reliable information, determining the most suitable features for achieving the best urban planning solution.     

Upper Secondary School Completion and the Business Cycle

Previous evidence suggests that enrollment in post‐compulsory education increases (decreases) in cyclical downturns (upturns). However, little evidence exists on whether enrollment is successfully transformed into completed education. This paper adds to the literature by analyzing the relationship between completion of upper secondary education and regional unemployment using Norwegian regional panel data on students graduating from compulsory school between 1981 and 2004. We find robust evidence that completion rates are countercyclical. Our results suggest that poor labor‐market conditions when starting upper secondary education have a lasting effect and motivate students to stay in school and graduate.     

The Diaries of a Cabinet Minister,Volume One,Minister of Housing 1964–66

While John R. Commons often referred to third sector organizations, such as associations, cooperatives, and trade unions, it is unclear how these organizations can be fitted into his transactional typology. This paper clarifies this problem by identifying two dimensions of bargaining, managerial, and rationing transactions: 1) the extent of legal equality of transactional participants, and 2) the extent of commonness of these participants' transactional interests. These dimensions enable defining the identity of the third sector in terms of a distinct variety of rationing transactions combining legal equality of transactional participants with significant commonness of their interests. The paper further explores several implications of this argument for new institutional economics, concerning the citizenship aspect of markets and hierarchies and the possibility of viewing third sector organizations as hybrids between markets and hierarchies. The paper concludes with a discussion of the implications for further research.
