Despite developments within planning theory challenging the ideal of the rational master plan it may be argued that there is still use for the production of knowledge through analysis in planning. However, the cultural complexity of today's planning contexts, and a move towards governance and entrepreneurial policies, makes it difficult to make places, to achieve social welfare and sustainability. Traditionally, the analysis of places has been done by architects and planners focusing on physical form, having an essentialist perspective of place resembling the theory of genius loci. In Norway, the planning authorities refined this methodology in the 1990s. This approach is, however, not in tune with a progressive view of places as multiple and dynamic social constructions, and may be accused of ‘symbolic violence’. If one is to take this view seriously and still be able to make plans, planning must also be based on other types of knowledge. In this article I argue for a socio‐cultural approach to reveal social representations and practices that make a place. I use the case of place‐making in Sandvika, a suburban ‘minicity’ outside Oslo, as an example of how a constructivist understanding differs from and may supplement an essentialist approach. 相似文献

Nonlinear relationships are common in economic theory, and such relationships are also frequently tested empirically. We argue that the usual test of nonlinear relationships is flawed and derive the appropriate test for a U‐shaped relationship. Our test gives the exact necessary and sufficient conditions for the test of a U shape in finite samples in a large class of models. 相似文献

Empirical monetary policy research has increased in the last decade, possibly because deregulation and explicit monetary targets have made monetary policy issues more interesting. In particular, within the inflation targeting framework it has been argued that inflation forecasts can be used as optimal intermediate targets for monetary policy, and the development of empirical models that have good forecasting properties is therefore important. This paper shows that a VAR model with long‐run restrictions, justified by economic theory, is useful for both forecasting inflation and for analysing other issues that are central to the conduct of monetary policy.

Becker and Murphy's theory is a well‐known contribution to economists on the discussion of addiction. This class of rational choice theory is still the most important reference for economists studying addiction. In this paper, the model and the economist's rational choice theory were challenged by modern neurobiological theory. The paper suggested reconstruction work of the standard inter‐temporal choice model along four lines to reduce the gap between the theory and the clinical definition of addiction: (1) a discount rate that varies; (2) revision of the concept consumption capital; (3) the possibility for genetic predisposition to addiction (even if the research up to now has not identified such a gene); and (4) social mechanisms that influence our behaviour. 相似文献

We suggest a novel perspective on the relationship between the stringency of environmental policies and foreign direct investment (FDI). We develop a political economy model with imperfect product market competition where local and foreign firms jointly lobby the local government for a favorable pollution tax. FDI is found to affect environmental policy, and the effect is conditional on the local government's degree of corruptibility. If the degree of corruptibility is sufficiently high (low), FDI leads to less (more) stringent environmental policy, and FDI thus contributes to (mitigates) the creation of a pollution haven. Our empirical results using panel data from 33 countries support the predictions of the model. 相似文献

Based on a randomized experiment, we estimate effects from notification to medical doctors of tighter monitoring of their Medical Certificates (MCs). Both the time prescribed by the doctor certificates for sick leave (prescribed sick leave) and the impact on the length of the actual sickness absence (actual sick leave) is studied. We find no effect on the total number of prescribed sick leave days. However, we do find an increase in both prescribed and actual sick leave with a 25% work inability. We also find that the notification letter causes an increase in actual sick leave (i.e. the number of reimbursed sick days). We discuss a number of potential explanations for this rather surprising result. 相似文献

On the jump activity index for semimartingales 总被引:1,自引:0,他引:1
Empirical evidence of asset price discontinuities or “jumps” in financial markets has been well documented in the literature. Recently, Aït-Sahalia and Jacod (2009b) defined a general “jump activity index” to describe the degree of jump activities for asset price semimartingales, and provided a consistent estimator when the underlying process contains both a continuous and a jump component. However, only large increments were used in their estimator so that the effective sample size is very small even for large sample sizes. In this paper, we explore ways to improve the Aït-Sahalia and Jacod estimator by making use of all increments, large and small. The improvement is verified through simulations. A real example is also given. 相似文献

The model of Akerlof, Dickens and Perry (2000) (ADP) predicts that low inflation may cause unemployment to persist at high levels. When applied to U.S. data, their results strongly rejected the conventional NAIRU model. We apply the ADP model to Swedish data. The fact that our Swedish data also reject the NAIRU model has a number of interesting implications for the Swedish economy and, potentially, for other European countries as well. The results indicate that raising the Swedish inflation target from 2 to 4 percent would bring long‐run unemployment down by several percentage points. The possibility of ADP‐type long‐run Phillips curves also across the euro countries may raise some concern about the EMU project. While detailed studies on other countries are needed, there is nothing to suggest that these non‐vertical Phillips curves would not differ considerably across the euro countries. Any single inflation level targeted by the ECB would then generate excess unemployment in individual member states. 相似文献

The practical relevance of several concepts of exogeneity of treatments for the estimation of causal parameters based on observational data are discussed. We show that the traditional concepts, such as strong ignorability and weak and super-exogeneity, are too restrictive if interest lies in average effects (i.e. not on distributional effects of the treatment). We suggest a new definition of exogeneity, KL-exogeneity. It does not rely on distributional assumptions and is not based on counterfactual random variables. As a consequence it can be empirically tested using a proposed test that is simple to implement and is distribution-free. 相似文献
