We point out that fiscal multipliers derived from SVAR-models include the predicted future path of policy instruments. After the initial shock, net taxes and government expenditures react to each other and are autocorrelated. In a counterfactual simulation, we report fiscal multipliers that abstract from these dynamic responses. 相似文献

We consider forecasting the term structure of interest rates with the assumption that factors driving the yield curve are stationary around a slowly time‐varying mean or ‘shifting endpoint’. The shifting endpoints are captured using either (i) time series methods (exponential smoothing) or (ii) long‐range survey forecasts of either interest rates or inflation and output growth, or (iii) exponentially smoothed realizations of these macro variables. Allowing for shifting endpoints in yield curve factors provides substantial and significant gains in out‐of‐sample predictive accuracy, relative to stationary and random walk benchmarks. Forecast improvements are largest for long‐maturity interest rates and for long‐horizon forecasts. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

This paper resolves two issues regarding the traditional capital asset pricing model with one risk-free asset which seem to
have been overlooked in the literature. First, it provides an elementary and complete proof of the two-fund separation theorem
which accounts for the fact that asset demand may become undefined if the limiting slopes of the investor’s indifference curves
are finite. Second, it shows that an additional limiting condition on investors’ risk aversions is generally necessary to
guarantee existence of an equilibrium. Moreover, a generalized existence result is formulated which includes investors who
in equilibrium may not invest in risky assets and a simple condition ensuring positive equilibrium asset prices is given. 相似文献

This study examines the state of the art in new service development (NSD) research published in the period between 1982, when the first NSD article appeared in an academic journal, and 2008. First, a multisource search was conducted, which resulted in the identification of 145 NSD‐related articles. Then, a content analysis was performed of these articles using multiple classifier variables with regard to general publication characteristics, focus of the research, and the research methodology that was employed. By examining the results, a number of developments in and patterns of scholarly research in NSD are revealed. More specifically, it appears that the greatest attention in the early writings was on a narrow set of NSD topics like critical success factors and the NSD process, which were predominantly investigated through large‐scale surveys with single respondents in the U.S., Canadian, and U.K. financial services industry. The analytical techniques that were used at that time were rather simple. In contrast, in recent NSD works there is an expansion of research topics (such as customer involvement and the organization of NSD) that are increasingly investigated in high‐tech service industries in Europe through qualitative research designs. Also, multiple respondent studies have started to appear in NSD investigations, while analytical techniques have also become more advanced. This pattern clearly uncovers signs of increasing maturation for the NSD discipline. In addition, some underresearched areas are identified, leading to suggestions for future research into this growing and important field. 相似文献

The aim of this paper is to review the usefulness of the software CAQDAS QSR—Nvivo-6 in a PhD. Thesis, which consisted of
finding the long-term psychological effects of experiences of imprisonment and torture for political reasons in their Chilean
survivors. For this research, it was created and administered an in-depth interview to 60 survivors, from which outcome was
9900 paragraphs, coded into 784 categories. The software QSR Nvivo-6 threw a report of frequencies, which were compared quantitatively
using Pearson’s χ
2 square test and cluster analysis. We conclude that the software facilitates the development of qualitative thematic content
analysis, simplifying the coding, analysis and display of data. In Addition, it is very useful when working with large quantities
of information, promoting the reliability and validity of studies. However, other aspects are also required to ensure the
rigor of a qualitative study. 相似文献

Since Poland has become a member of the European Union, free market activities have increased dramatically. The purpose of this study is to explore university students' perceptions of personal selling as a career in Poland. Using logistic regression and Z-test methodologies, we analyzed the perceptions of 114 students. The results confirm the findings of previous studies that personal factors play a significant role in predicting students' perception of sales profession as a career. The findings presented in this study show that Polish students have a biased perception about sales as a career; however, interestingly, few dimensions show a significant effect. Understanding students' perceptions of the sales profession will help corporate recruiters achieve their goals by selecting those students most likely to excel in sales careers. 相似文献

The Tipping Point of Design: How Product Design and Brands Interact to Affect Consumers’ Preferences
Existing research on product design has demonstrated the importance of aesthetics in generating favorable consumer responses. However, the literature has only recently begun to explore if and to what extent the impact of product design is influenced by brand strength. Whereas some research indicates that strong brands may benefit less strongly from aesthetically attractive designs, other research suggests that attractive designs are more persuasive when they are paired with a strong brand. In this research, these two competing predictions were tested through three studies with German car buyers. In Study 1, participants were exposed to a fictitious car that was paired with a randomly chosen brand name. In Study 2, participants were presented with a set of existing cars and were asked to choose one. Both studies yield converging evidence and show that product design and brands interact in a positive fashion, suggesting that attractive designs exert a greater influence on consumers’ decision processes when they are accompanied by a strong brand. Study 3 extended these findings by demonstrating that strong brands only increase the impact of attractive designs when perceived risk is high but not when it is low. 相似文献
