While voices in the comparative urbanism literature call for researchers to approach comparison with more experimental and critical methodologies, there remains no consensus on how to design and realize these studies. This essay examines the implications of comparative urbanism for researching the ‘Asian City'. Given the critique of existing modes of comparison embedded in recent calls for a new comparative urbanism, researchers are faced with a number of pressing questions: How do we approach this ‘regional' topic in a way that both resists categorizing the ‘Asian City' as an exotic ‘other', elevating it onto a mythical pedestal, yet appreciates its differences, localisms and unique ‘cosmopolitan vernacular' (Clifford, 1997; Werbner and Modood, 1997)? This essay thus highlights the multiple challenges of applying the comparative lens to the ‘Asian City', arguing that broader conceptualizations of the ‘Asian City' help to address the dangers in isolating Asian research into its own canon of parochial urban theory and offering a greater diversity of possibilities for justifying case selection in comparative approaches. In doing so, we hope that this essay responds to the comparative turn by illuminating to some extent its inherent complexity and methodological challenges. 相似文献

We analyze a two-attribute single item procurement auction that uses yardstick competition to settle prices. The auction simplifies the procurement process by reducing the principal’s articulation of preferences to simply choosing the most preferred offer as if it was a market with posted prices. This is done simply by replacing the submitted sealed bids by yardstick bids, computed by a linear weighting of the other participants’ bids. We show that there is only one type of Nash equilibria where some agents may win the auction by submitting a zero price-bid. Using a simulation study we demonstrate that following this type of equilibrium behavior often leads to winner’s curse. The simulations show that in auctions with more than 12 participants the chance of facing winner’s curse is around 95 %. Truthful reporting, on the other hand, does not constitute a Nash equilibrium but it is ex post individually rational. Using a simulation study we demonstrate that truthful bidding may indeed represent some kind of focal point. 相似文献

This article evaluates irrigated agriculture sector response and resultant economic impacts of climate change for a part of the Murray Darling Basin in Australia. A water balance model is used to predict reduced basin inflows for mild, moderate and severe climate change scenarios involving 1, 2 and 4°C warming, and predict 13, 38 and 63% reduced inflows. Impact on irrigated agricultural production and profitability are estimated with a mathematical programming model using a two‐stage approach that simultaneously estimates short and long‐run adjustments. The model accounts for a range of adaptive responses including: deficit irrigation, temporarily following of some areas, permanently reducing the irrigated area and changing the mix of crops. The results suggest that relatively low cost adaptation strategies are available for a moderate reduction in water availability and thus costs of such a reduction are likely to be relatively small. In more severe climate change scenarios greater costs are estimated. Adaptations predicted include a reduction in total area irrigated and investments in efficient irrigation. A shift away from perennial to annual crops is also predicted as the latter can be managed more profitably when water allocations in some years are very low. 相似文献

Virtual customer integration (VCI) involves customers throughout all stages of the new product development process. Firms across industries have started to experiment with virtual user integration and expect to utilize their knowledge, creativity, and judgment. However, little research exists that looks at the motivations of customers and managers to engage in virtual product development projects. In this paper we try to identify the triggers for virtual customer integration (VCI) from the manager's as well as from the customer's perspective. Using Ajzen's Theory of Planned Behavior we aim at explaining managers' motivation for the adoption of VCI based on a sample of 104 managers engaged in the product development process of manufacturing firms of medical technology. Drawing on motive research, we test six categories of customer motivations to engage in VCI projects on a sample of 105 users of medical technology. The results show that for mangers subjective norms and attitude predict the intention to use VCI. For customers, interest in innovation and product improvement are the most important drivers, whereas monetary compensation and prestige are not significant, and surprisingly the desire to help people even has a negative impact on the participation of VCI. 相似文献

In this paper we analyze a stochastic dynamic advertising and pricing model with isoelastic demand. The state space is discrete, time is continuous and the planing horizon is allowed to be finite or infinite. A dynamic version of the Dorfman–Steiner identity will be derived. Explicit expressions of the optimal advertising and pricing policies, of the value function and of the optimal advertising expenditures will be given. The general results will be used to analyze the case of impatient customers. Furthermore, particular time inhomogeneous models and homogeneous ones with and without discounting will be examined. We will study the social efficiency of a monopolist's optimal policies and the consequences of specific subsidies. From a buyer's perspective, our analysis reveals that waiting – when looking at (immediate) expected prices – is never profitable should two or more units be available. But we will also prove that the sequence of average sales prices is monotone decreasing. Moreover, the techniques applied to solve the discrete stochastic advertising and pricing problem will be used to solve a related deterministic control problem with continuous state space. 相似文献

Tests for heteroskedasticity in the classical linear regression framework typically require the researcher to specify the form of variance heterogeneity. This paper proposes a simulation-based test with power to detect unspecified forms of heteroskedasticity. 相似文献

The industrialization of agriculture and the potential problem of small-scale farmer marginalization calls for a fresh approach to the design of agribusiness supply chain arrangements in developing countries. The objective of the paper is to contribute to a better understanding of institutional arrangements that can promote stable smallholder agribusiness contracting arrangements in a developing country context. A case study approach, incorporating a transaction cost framework, is used to test whether trust can significantly change the contract characteristics of supply. The results suggest that although the presence of trust can influence the contract characteristics of a supply arrangement, it may not be significant because of other factors in a developing country context. Bearing this in mind, a number of institutional arrangements are recommended in order to promote more stable contract conditions. 相似文献

Companies in financial distress have an incentive to take on high-risk/high-reward projects, known as ??bankruptcy behavior.?? This paper investigates the activity of bankruptcy behavior outside of the corporate setting by analyzing the effects of the overtime structure in the NFL relative to College Football. In overtime, the first team to score in the NFL wins. In college football, however, both teams in overtime get a chance to score and the winner is decided when one team outscores the other. This structure causes different strategies for the NFL teams approaching overtime relative to college football teams. Using the variance in scoring throughout the game, I find evidence that NFL teams take on more risk late in the game to avoid overtime, or act as if they have bankruptcy behavior. 相似文献
