In this article, we define a new construct for urban economic and investment analysis, which revisits the conventional wisdom that investment in real estate development is riskier than investment in stabilized property assets. This new construct, referred as a “development asset value index” (DAVI), is a value index for newly developed properties (only) in a given geographical property market. It tracks longitudinal changes in the highest and best use (HBU) value of locations, and it reveals developer and landowner behavior taking advantage of the optionality inherent in land ownership. In particular, the DAVI reflects developers' use of flexibility in the exercise of the call option to (re)develop the property to any legal use and density. We empirically estimate a DAVI for commercial property (i.e., central locations) and compare it with a corresponding traditional transaction‐price‐based property asset price index (PAPI) corrected for depreciation. We believe that the difference primarily reflects the realized value of flexibility in land development. We find that the DAVIs display greater value growth and are smoother over time and less cyclical than their corresponding PAPIs for the same locations. This suggests that developers successfully use flexibility, and that development may be riskier than stabilized property investment due primarily only to leverage effects (construction costs). Practical implications are also discussed. 相似文献

In this paper we develop the concept of compromising accounts as a distinctive approach to the analysis of whether and how accounting can facilitate compromise amongst organizational actors. We take the existence of conflicting logics and values as the starting point for our analysis, and directly examine the ways in which the design and operation of accounts can be implicated in compromises between different modes of evaluation and when and how such compromises can be productive or unproductive. In doing so, we draw on Stark’s (2009: 27) concept of ‘organizing dissonance’, where the coming together of multiple evaluative principles has the potential to produce a ‘productive friction’ that can help the organization to recombine ideas and perspectives in creative and constructive ways. In a field study of a non-government organization, we examine how debates and struggles over the design and operation of a performance measurement system affected the potential for productive debate and compromise between different modes of evaluation. Our study shows that there is much scope for future research to examine how accounts can create sites that bring together (or indeed push apart) organizational actors with different evaluative principles, and the ways in which this ‘coming together’ can be potentially productive and/or destructive. 相似文献

Biologists and conservation advocates have expressed grave concern over perceived threats to biological diversity. ``Biodiversity prospecting' – the search among naturally occurring organisms for new products of agricultural, industrial, and, particularly, pharmaceutical value – has been advanced as both a mechanism and a motive for conserving biological diversity. Economists and others have attempted to estimate the value of biodiversity for use in new pharmaceutical project research. In this paper we apply a new approach to estimating values: we employ two models of competition among differentiated products. Each model confirms previous findings that the value to private researchers of the ``marginal species' is likely to be small. The models can have very different implications with respect to social values, however. These findings underscore the need for a better understanding of the true meaning of diversity.Resources for the Future 相似文献

The decline in the costs of communicating, coordinating, and collaborating across firms in the value chain has led to the emergence of new business models—virtually integrated companies, retail "bricks and clicks" organizations, and networks like AOL and eBay—that can be used by all kinds of companies to exploit new opportunities. With these new organizations comes a need for new governance practices—practices that permit swifter decisions, best practice sharing, and more focused operations.
The author argues that improvements in governance should focus on achieving the following:

Organization structures that leverage external alliances while improving internal collaboration. This involves gaining acceptance of and support for a common aspiration across the company—the goal of deploying financial and human resources, complemented by technology, to build shareholder wealth.

The Narver and Slater (Narver, J.C., and Slater, S.F.: The Effect of Marketing Orientation on Business Profitability. Journal of Marketing 54 (1990): 20–35.) market orientation scale is tested in the context of the transition economies of central Europe and found to be both valid and reliable. Relationships between market orientation and both marketing strategy and performance broadly follow predictions from the Western literature indicating that the adoption of a market orientation is equally applicable in transition as in Western economies. A number of different approaches, however, are evident in the transition economies suggesting that other business orientations may coexist with a market orientation creating a richer and more complex set or organizational drivers. 相似文献

The goal of universal service has dominated the telecommunications policy landscape for at least the past half century. This policy objective has been promoted with cross subsidies from long-distance telecommunications services to subscribers to local telecommunications service. The economic rationale for these cross subsidies is network externalities. In this paper, we show that: (1) the presence of network externalities, even if substantial in overall magnitude, does not generally justify a subscribership subsidy, even a well-designed one; and (2) the empirical realities of telecommunications markets make it unlikely that subscribership subsidies of any kind will increase social welfare. 相似文献

A regulated upstream monopolist provides an input to firms in a downstream market. If the monopolist enters the downstream market, a natural concern is that it will act so as to raise its downstream rivals' costs. An offsetting incentive is that a higher downstream price will reduce demand for the input, which reduces the monopolist's profit. Conditions under which one incentive dominates the other are derived. The monopolist may desire to lower its downstream rivals' costs rather than raise them. These findings suggest that regulatory policy towards such downstream entry should not focus exclusively on the ability to discriminate. 相似文献

We use Demographic and Health Surveys (DHS) to compare “poverty” at two or more points in time within and between African countries. Our welfare measure is an index resulting from a factor analysis of various household characteristics, durables, and household heads’ education. An advantage of this measure is that for intertemporal and intraregional comparisons, we need not rely on suspect price deflators and currency conversion factors. The wide availability and similarity of questionnaires of the DHS facilitate comparisons over both time and countries. Our results generally show declines in poverty during the previous decade, largely due to improvements in rural areas. 相似文献

In this paper the validity of the monetary exchange rate model in the long run for the Canadian-U.S. dollar exchange rate is examined. The primary test employed is the Johansen (1991) and Johansen and Juselius (1990) cointegration technique. The effects of dummy variables and lag specification on the statistical inference are considered, and Monte Carlo simulations based on the estimated parameters are employed. Despite the use of the longest data set yet for the Canadian case, no evidence is found in favour of the monetary exchange rate model using the Johansen procedures. This result is confirmed by several other cointegration procedures. JEL Classification: F31; F41
La faillite du modèle monétaire du taux de change pour les dollars canadien et américain. Ce mémoire examine le modèle monétaire du taux de change pour savoir s'il est validé par l'expérience canado-américaine en longue période. Le test principal utilisé est la technique de cointégration de Johansen (1991) et Johansen et Juselius (1990). Les effets des variables fictives et de la spécification de la structure de délais sur l'inférence statistique sont considérés, et on utilise des simulations de Monte Carlo fondées sur les paramètres calibrés. Malgré le fait qu'on fait appel à la plus longue série chronologique utilisée dans ce type d'analyse à ce jour, on ne trouve aucun support du modèle monétaire du taux de change en utilisant les procédures de Johansen. Ce résultat est confirmé par l'utilisation de plusieurs autres procédures de cointégration. 相似文献
