This paper compares the investment policies and returns for portfolios of stocks and bonds with and without up to three categories of real estate. Both domestic and global settings are examined, with and without the possibility of leverage. The portfolios were generated via the dynamic investment model based on the empirical probability assessment approach applied to past (joint) realizations of returns, both with and without correction for "smoothing" in the real estate data series. Our principal findings are: (1) the gains from adding real estate, on a semi-passive (equal-weighted) basis, to portfolios of either U.S. or global financial assets were relatively modest; in contrast, (2) the gains from adding real estate to the universe of U.S. financial assets under an active strategy were rather large (in some cases highly statistically significant), especially for the very risk-averse strategies; (3) the gains from adding U.S. real estate to a universe of global financial assets under an active strategy were mixed, although generally favorable for the highly risk-averse strategies; (4) correcting for second-moment smoothing in the real estate returns series had a relatively small impact for the more risk-tolerant strategies; and (5) there was some evidence that desmoothing resulted in improved probability estimates.  相似文献

Following the trend in the private sector, standardized environmental management systems (EMSs) have been introduced in several local authorities around the world. When the tool is transferred from the private sector to the public, one can ask how useful the tool is in the new environment, since the private and the public sectors are two different types of social sphere, with different institutional logics. Taking a closer look at the situation in Sweden, this paper aims to investigate the applicability of standardized EMSs in local authorities and the public sector in general. Based on qualitative interviews with public officers in two municipalities in Sweden, it is argued that EMSs are useful in municipalities. However, the study also reveals that an EMS seems to be more suitable for technical service administrations and municipally owned companies than social service administrations.

This paper describes and analyses the approach taken by four well-known Swedish companies to management control following takeover. The findings suggest two factors which can explain how the management control systems were designed and used after an acquisition: the corporate strategy of the acquirer and the business strategy of the acquired company. The case studies show how these forces could impose mutually inconsistent requirements on the management control system of the acquired firm, and also how these inconsistencies were resolved.  相似文献

We explore the efficacy of price and quantity controls in a dynamic setup in which the decisions of some agents are irreversible. The assumption of irreversibility is shown to improve the performance of a tax relative to that of a system of tradable quotas and significantly alter the equilibrium behavior of agents. We nevertheless conclude that taking into account the fact that agents’ decisions may be irreversible does not lead to policy implications significantly different from those reached in a simpler model in which irreversibility is ignored.  相似文献

A simple N-country specific-factor-type model with imperfectly mobile labour is developed. It is shown that the effects of country-specific productivity shocks hitting a small country have fundamentally asymmetric effects: A positive shock will be accommodated by a moderate wage increase and sizeable in-migration, whereas a negative shock will be accommodated by a significant decrease in wages and moderate out-migration. It is argued that the results of the model are consistent with the recent Irish experience. The welfare effects of small economic fluctuations are also discussed.  相似文献

We investigate the out-of-sample forecasting performance of various monetary aggregates in four-variate models of real output growth, inflation, changes in an interest rate, and nominal money growth from 1992 to 2004 using vector autoregressive (VAR) and regime-switching (RS) VAR models. We consider both Divisia and simple sum monetary aggregates for M1, M2M, M2, and M3 as well as sweep-adjusted M1 measures. We find little evidence that either aggregation method or level of aggregation has a big impact on the forecasting performance of our model with respect to inflation and real output growth. Our results indicate that VAR models with monetary aggregates appear to produce at best marginal improvements in RMSE over VAR models that omit money growth altogether. We also find that RS-VAR models usually provide better one quarter ahead forecasts than comparable VAR models, but often did worse when forecasting inflation four quarters ahead.  相似文献

This paper identifies areas, which may cause problems when establishing service supply relationships. Case research has been conducted within the service division of a global manufacturing company, analysing 11 instances where the company established or attempted to establish a relationship with a supplier to provide services as part of their offering to the end-customer. Four problem areas are identified through inductive case analysis. First, writing legal agreements for service exchanges. Second, clearly specifying service processes to be transferred to suppliers. Third, handing over service delivery to suppliers. Fourth, losing control over the relationship with the customer. These problems expand on already known problems of establishing supply relationships. Suggestions for how the problems may be moderated are also provided.  相似文献

Empirical studies of regional wage formation and interregional migration routinely include the regional unemployment rate as indicator of local labour market tightness. However, these studies are usually motivated by economic theories that emphasize transition probabilities between unemployment and employment, and the unemployment rate is an imperfect proxy for these probabilities. We use a large micro data set to compute estimates of the rate of outflow from unemployment for 90 Norwegian travel‐to‐work areas. The outflow rates perform better than traditional measures of regional labour market tightness in panel data analyses of regional wages and interregional migration.  相似文献

U.S. consumers are increasingly concerned about food safety, environmental degradation, and animal welfare at the live animal production stage. In response, meat suppliers are developing food credence certification to secure market access, increase margins, and increase overall demand. The objective of this paper is to characterize the demand and the market potential of a credence certification program for pork in the United States. Information regarding consumer willingness to pay for the conventional and certified products is derived from a latent class random utility model. The willingness to pay estimates are subsequently compared to the costs of implementing the programs at the producer, packing, and retailing stages. One of the findings in this study is that a significant segment of consumers would purchase certified pork at the anticipated marginal cost of certification. Therefore, future studies should consequently focus on the welfare economic implications on consumers and meat suppliers from incomplete adoption of voluntary certification programs on the part of both producers and consumers. Aux États‐Unis, les consommateurs se préoccupent de plus en plus de la sécurité alimentaire, de la dégradation de l'environnement et du bien‐être des animaux au stade de la production. En réponse à ces inquiétudes, les fournisseurs de viande travaillent à l'élaboration de programmes de certification des aliments pour garantir l'accès au marché, accroître les marges ainsi que la demande globale. Le présent article vise à caractériser la demande et le potentiel de marché d'un programme de certification du porc aux États‐Unis. L'information concernant la volonté de payer du consommateur pour des produits classiques et des produits certifiés a été tirée d'un modèle d'utilité aléatoire à structure latente. Les estimations de la volonté de payer ont ensuite été comparées aux coûts de mise en place des programmes aux stades de la production, de l'abattage et de la vente au détail. L'un des résultats de l'étude a montré qu'un nombre important de consommateurs achèterait du porc certifié au coût marginal prévu de la certification. Des études ultérieures devraient donc se pencher sur les répercussions économiques de l'adoption incomplète des programmes de certification volontaires de la part des producteurs et des consommateurs sur le bien‐être des consommateurs et des fournisseurs de viande.  相似文献
