The authors detail an urban economics experiment that is easily run in the classroom. The experiment has a flexible design that allows the instructor to explore how congestion, zoning, public transportation, and taxation levels determine the bid–rent function. Heterogeneous agents in the experiment compete for land use using a simple auction mechanism. Using the data that is collected, a bid–rent function is derived, and the experimental treatment is altered over the course of three sessions to uncover core concepts in urban economics. Moreover, this provides a tangible experience that can be used to help undergraduates relate to urban issues such as the steep rent gradient found around many larger colleges and universities.  相似文献

Design may be seen as one of several key factors contributing to new product development, along with research and development, marketing, manufacturing, purchasing, etc. More and more, creative design comes to the fore, and many companies believe that superior design will be the key to winning customers. It has the ability to create corporate distinctiveness and also possesses the potential to give a product an individual or new look. Furthermore, the model of open innovation suggests that firms can and should use external and internal knowledge flows in order to create valuable ideas, and also internal and external paths to the market. Also, in the design process, a common trend toward external design skills has emerged in recent years. Due to cost and control factors, firms are increasingly outsourcing design activities. By using a sample of Belgian companies, this paper explores the contribution of design activities to product market performance. While there is mounting evidence that design can be seen as a strategic tool to successfully spur sales of new product developments at the firm level, the topic of design innovation has not yet been linked to the open innovation concept. In this paper, it is empirically tested whether design activities conducted in house differ in their contribution to new product sales from externally acquired design. So, do design activities that have been developed only with internal resources lead to a greater success than those that have been carried out with external sources of knowledge? Using a large cross‐section of manufacturing and service firms, the effects on sales of products new to the market and of imitations or significantly improved products of the firm are investigated. At first glance, the findings indicate that externally acquired design is not superior to in‐house design activities: the results show that only design activities that are mainly conducted with internal knowledge sources play a crucial role regarding the product innovation's success with market novelties. Design conducted in collaboration with external partners, however, has no significant influence. This is not the case for imitations, that is, products only new to the firm. Their success is also influenced by design activities developed with external collaborators. This effect is robust for several modifications of the model specification. In contrast to earlier literature on new technological developments, this paper argues that external design may not affect the sales of market novelties as the “market news” may spill over quickly to rivals through common suppliers including external designers.  相似文献

Japan is recognised as a major competitor in world markets but is less well‐known as an attractive market in its own right. This paper proposes that with the right strategies it is possible to successfully penetrate the difficult Japanese market. Problems and opportunities presented by the market are discussed, and some of the findings of a survey of Japanese and German managers in Japan and German‐based managers are reviewed. The paper covers the survey findings on market characteristics, barriers to entry, information requirements, factors contributing to success and methods of market entry. German and UK sources of information and advice on the Japanese market are given for those interested in pursuing the matter further.  相似文献

This paper constructs a number of possible core measures of inflation using singular spectrum analysis (SSA). Annual changes in monthly inflation are decomposed into its trend, oscillatory and noise components in order to develop an understanding of the trend and cyclicality in South African headline inflation. Three cyclical components with differing amplitude and frequency are identified. The trend and cyclical components of inflation are found to be a good approximation of core inflation, the inertial part of inflation. These core measures are compared with other candidate core measures based on the properties of a good core inflation measure. Generally, the SSA measures outperform commonly used measures of core inflation based on both in‐ and out‐of‐sample performance.  相似文献

This article explores the added value of the HR function as it is perceived by three groups of managers: top managers, HR managers and line managers. Despite the fact that literature about strategic HRM focuses almost exclusively on the value of the HR function as a strategic partner, it was assumed that its perceived value for the business would not be restricted to the area of strategy formulation and implementation. Several 'result domains' can be distinguished in which the HR function can deliver value to the business. Based on our review of the literature, the degree of strategic involvement of the function was used as a second perspective to investigate its perceived added value. To examine our propositions, a qualitative study was carried out in which 97 HR managers, 38 top managers and 178 line managers participated. The results confirm our thesis that the perceived value of the HR function contains more than just the fulfilment of its role as a strategic partner. Based on our results, an integrated model for the perceived value of the function has been developed.  相似文献

In the first year after President Yudhoyono's re-election, Indonesian politics continued to evolve in largely familiar patterns. Contrary to the expectations of some observers, Yudhoyono's strong popular mandate and his Democratic Party's newly won parliamentary plurality did not result in significant changes to the president's cautious style of governing or the fickle nature of president–parliament relations. Most political parties also opted for continuity over change, electing or re-electing established figures as leaders despite high levels of public dissatisfaction with their performance. The fact that the 2009 election failed to generate any new momentum for reform does not augur well for the remainder of Yudhoyono's second term. Although the basic parameters of Indonesia's democracy remain intact, political developments during 2010 have also confirmed a pattern of stagnation that is likely to see Indonesia barely muddle through as a reasonably stable yet low-quality democracy.  相似文献

We develop a model with many advertisers (products) and many advertising markets (media). Each advertiser sells to a different segment of consumers, and each medium is targeting a different audience. We characterize the competitive equilibrium in the advertising markets and evaluate the implications of targeting. An increase in targeting leads to an increase in the total number of consumer‐product matches, and hence in the social value of advertising. Yet, targeting also increases the concentration of firms advertising in each market. Surprisingly, we then find that the equilibrium price of advertisements is first increasing, then decreasing, in the targeting capacity. We trace out the implications of targeting for competing media. We distinguish offline and online media by their targeting ability: low versus high. As consumers’ relative exposure to online media increases, the revenues of offline media decrease, even though the price of advertising might increase.  相似文献

We consider a robust version of the classic problem of optimal monopoly pricing with incomplete information. In the robust version, the seller faces model uncertainty and only knows that the true demand distribution is in the neighborhood of a given model distribution. We characterize the pricing policies under two distinct decision criteria with multiple priors: (i) maximin utility and (ii) minimax regret. The equilibrium price under either criterion is lower then in the absence of uncertainty. The concern for robustness leads the seller to concede a larger information rent to all buyers with values below the optimal price without uncertainty.  相似文献

Is gold a hedge, defined as a security that is uncorrelated with stocks or bonds on average, or is it a safe haven, defined as a security that is uncorrelated with stocks and bonds in a market crash? We study constant and time‐varying relations between U.S., U.K. and German stock and bond returns and gold returns to investigate gold as a hedge and a safe haven. We find that gold is a hedge against stocks on average and a safe haven in extreme stock market conditions. A portfolio analysis further shows that the safe haven property is short‐lived.  相似文献
