We analyze the role of house prices and stock prices in the monetary‐policy transmission mechanism in the US, using a structural vector autoregressive model. If we allow the interest rate and asset prices to react simultaneously to news, we find different roles for house prices and stock prices in the monetary transmission mechanism. Following a contractionary monetary‐policy shock, stock prices fall immediately, while the response in house prices is more gradual. Regarding the systematic response in monetary policy, stock prices play a more important role than house prices. As a consequence, house prices contribute more than stock prices to fluctuations in gross domestic product and inflation.  相似文献

Two decades ago, the rules governing the provision of piped municipal water supply in Mumbai became linked to the policy frameworks governing eligibility for a property titling scheme. This article outlines the ideological basis and practical implications of the shift, as well as the contradictions of the new regulatory regime. The article demonstrates how these contradictions have been mediated by the material and practical knowledge, embodied expertise, local authority and wide‐ranging socio‐political work of two sets of actors: municipal water engineers and a cast of characters known locally as ‘plumbers’. The social, political and hydraulic imaginaries animating the work of ‘plumbing’ are bound up with a temporal and spatial imaginary distinctly at odds with the network‐flow conception of hydraulic engineering within which the work of water supply planning and distribution in Mumbai is conceptualized, materialized and institutionalized. The hydraulic and legal contradictions of these clashing infrastructural idioms––of flow and event––have rendered the regulatory framework highly unstable. These contradictions eventually erupted in Mumbai's waterscape, leaving the city's water infrastructures suspended in a highly politicized state of limbo between dueling infrastructural imaginaries.  相似文献

The present study investigates a potential preventive factor in relation to workplace bullying. Specifically, we examine how climate for conflict management (CCM) may be related to less bullying, increased work engagement, as well as whether CCM is a moderator in the bullying engagement relationship. The study was based on a cross-sectional survey among employees in a transport company (N = 312). Hypotheses were tested simultaneously in a moderated mediation analysis which showed that bullying and job engagement were related (H1), CCM was related to less reports of bullying (H2), CCM was related to work engagement (H3) and that CCM was indirectly related to job engagement through bullying (H4), but only when CCM was weak (H5). That is, CCM moderated the relationship between bullying and work engagement in that this relationship only existed when CCM was low. The present study contributes to theory within this research field by showing that organizational measures may not only prevent bullying, but may also affect how employees react when subjected to bullying. Furthermore, the effect of climate in relation to bullying may be down to the narrow bandwidth facet of CCM. The study informs employers how they may act to prevent bullying while also reducing the potential negative outcomes of those cases of bullying that inevitably will show up from time to time.  相似文献

What are the long-term effects of universal preschool programs on child outcomes? We review 26 studies using natural experiments to estimate the effects of universal preschool programs for children aged 0–6 years on child outcomes measured from third grade to adulthood. Studies comparing universal preschool with a mix of parental, family, and private modes of care show mixed effects on test scores and on measures related to health, well-being, and behavior. All estimates for outcomes related to adequate primary and secondary school progression, years of schooling, highest degree completed, employment, and earnings indicate beneficial average effects of universal preschool programs. Three of the included studies calculate benefits-to-costs ratios and find ratios clearly above one. Universal preschool tends to be more beneficial for children with low socioeconomic status and there are not consistently different effects for boys or girls. Only three studies compare two alternative types of universal preschool programs in terms of long-term outcomes.  相似文献

The Role of the Exchange Rate as a Shock Absorber in a Small Open Economy   总被引:2,自引:0,他引:2  
This paper analyses interactions between the real exchange rate and business cycles in a small open economy like Norway. Using a structural vector autoregression model, the role of different shocks are analysed, to investigate to what extent the real exchange rate is absorbing shocks, or a source of shocks itself. The results are ambiguous. Output and the real exchange rate are mainly explained by separate shocks, so that relinquishing exchange rate independence should come at little cost. However, the importance of nominal shocks in the business cycle emphasises that stabilisation is possible. Hence, remaining monetary independence may be attractive.  相似文献

International transit traffic between countries can be expected to increase in the future. This paper investigates whether international policy coordination is appropriate in the case of international transit traffic causing a local environmental externality. This issue is analysed in a two-country model where traffic is used as an input in production. It is found that individual optimization of the countries is likely to result in an outcome with less than optimal international traffic, i.e. too little pollution compared with optimum.  相似文献

Along with individual corporate management and regulatory matters for instance within EU regime Solvency II, Internal Risk Models are very important for major general insurance companies. Of crucial importance in building these internal models, is the stochastic modelling of large claims and in particular, the selection and parameterization of suitable probability distributions for the amount and number of claims based on empirical data. To this end, in practice, a visually-based methodology is more appropriate and workable than strict mathematical approaches. Based on a practical case study, this paper provides some insight into a visually-based methodology for internal risk models.  相似文献

Index tracking aims at replicating a given benchmark with a smaller number of its constituents. Different quantitative models can be set up to determine the optimal index replicating portfolio. In this paper, we propose an alternative based on imposing a constraint on the q-norm (0?<?q?<?1) of the replicating portfolios’ asset weights: the q-norm constraint regularises the problem and identifies a sparse model. Both approaches are challenging from an optimization viewpoint due to either the presence of the cardinality constraint or a non-convex constraint on the q-norm. The problem can become even more complex when non-convex distance measures or other real-world constraints are considered. We employ a hybrid heuristic as a flexible tool to tackle both optimization problems. The empirical analysis of real-world financial data allows us to compare the two index tracking approaches. Moreover, we propose a strategy to determine the optimal number of constituents and the corresponding optimal portfolio asset weights.  相似文献

In vielen Unternehmen stellt die Marketing- und Vertriebsorganisation eine permanente Baustelle dar. Problematisch ist v.a. die Ausrichtung der zahlreichen Teilfunktionen mit Marketing- und Vertriebsaufgaben auf die Bedürfnisse des Kunden. Zunehmend setzen Unternehmen Techniken des Prozessmanagements ein, um Kundenorientierung sicherzustellen. Dieser Beitrag geht auf die Hintergründe ein. Er liefert zudem empirische Ergebnisse zur derzeitigen Prozessorientierung deutscher Unternehmen in Marketing und Vertrieb, die auf positive Effektivit?ts- und Effizienzwirkungen eines prozessorientierten Marketing hindeuten.  相似文献
