We argue for a new approach to examining the relationship between tariffs and growth. We demonstrate that more can be learned from time series analyses of the experience of individual countries rather than the usual panel data approach, which imposes a causal relation and presents an average coefficient for all countries. Tentative initial results using simple two-variable cointegrated VAR models suggest considerable heterogeneity in the experiences of the countries we look at. For most, however, there was a negative relationship between tariffs and levels of income for both the pre- and post-Second World War periods. However, in the second half of the twentieth century, the causality ran from income to tariffs: that is, countries simply liberalized as they got richer. Policy decisions based on the usual panel approach might thus be very inappropriate for individual countries. 相似文献

This paper performs a multivariate cointegration analysis of UK money demand 1873–2001, and illustrates how a long-run time
series analysis may be conducted on a data set characterized by turbulent episodes and institutional changes. We suggest accounting
for the effects of the two world wars by estimating additive data corrections, thereby allowing the propagation of war-time
shocks to be fundamentally different from the transmission of peace-time innovations. In addition, the corrected series may
be used in counterfactual event studies to assess the impacts of special events. In the empirical analysis we find a single
equilibrium relationship relating velocity to opportunity costs, and we identify a significant link between excess money and
inflation. After accounting for the turbulent periods, the equilibrium structure is reasonably stable over a period of 130 years.
The empirical analysis was carried out using the OxMetrics software, see Doornik (2002). Ox procedures to estimate the vector equilibrium correction model with additive corrections are available from the author

Although 50 years of scientific work has been invested in building retrospective economic time series, their reliability is
still debated, a good example being the two competing nineteenth century French GNP series. Instead of trying to bring up
some new details to gauge their respective accuracy, we propose a different route, i.e. testing the intrinsic features of
these two series, in absolute terms first, then by benchmarking them to a non-retrospective time series. In order to do that,
we rely on new mathematical tools—wavelet spectrum analysis—developed in signal processing. This leads to a new approach,
which separates the accuracy of a series between amplitude and time variations, and brings nuanced conclusions as to which
of the two series tested is the best: indeed, since a trade-off is almost inescapable between the two criterions of accuracy,
the statistical quality of one retrospective time series tends to linger either on one side (amplitude level) or the other
(time variations). Our study also shows that variance distribution along the time axis is a good proxy for complex retrospective
series accuracy.

The effects of filled waiting time and service provider control over the delay on evaluations of service 总被引:1,自引:0,他引:1
Shirley Taylor 《Journal of the Academy of Marketing Science》1995,23(1):38-48
This article reports on an experiment that investigated the effects of a delay, perceived control over a delay, and the extent
to which time was filled during the delay on various performance evaluations in a service encounter. It was determined that
delays lower customers’ overall evaluations of service and of the tangible and reliability attributes of the service in particular.
When delayed, performance evaluations were affected by whether the service provider was perceived to have control over the
delay and whether the customer’s waiting time was filled. Overall performance evaluations and performance evaluations of tangibility,
reliability, and responsiveness were highest when perceived service provider control was low and the waiting customer’s time
was filled. These evaluations were lowest when perceived service provider control was high and waiting time was not filled.

Modelling trends and cycles in economic time series: historical perspective and future developments 总被引:1,自引:1,他引:0
Terence C. Mills 《Cliometrica》2009,3(3):221-244
This paper provides a retrospective on the modelling of trends and cycles in economic time series and considers where the
research agenda currently stands and where future developments might lie. A brief survey of the early empirical research on
trends and cycles is first provided before attention is focused on four papers published in 1961—our ‘annus mirabilis’ of
trend and cycle modelling—which we argue have been ‘prime movers’ in various aspects of research in this area. The links from
these papers to current research issues are then teased out before the likely future directions of research in both theoretical
and applied aspects of the modelling of trends and cycles are considered.

In this paper, we examine the large shocks due to major economic or financial events that affected U.S. macroeconomic time
series on the period 1860–1988, using outlier methodology. We show that most of these shocks have a temporary effect, showing
that the U.S. macroeconomic time series experienced only few large permanent shifts in the long term. Most of these large
shocks can be explained by major recessions and World War II as well as by monetary policy for the interest rate data. We
also find that some economic events seem to have the same effect (immediate, transitory or permanent) on a number of macroeconomic
series. Finally, we show that most macroeconomic time series do not seem inconsistent with a stochastic trend once we adjusted
the data for these shocks. 相似文献

超市通道费法律调整若干问题探讨——再论“零供”关系法律调整 总被引:1,自引:0,他引:1
超市通道费(进场费)是近年来社会议论的热点问题之一.<零售商供应商公平交易管理办法>颁布后,有关该问题的争论仍在延续.有人认为<办法>首次禁止了进场费.也有人认为<办法>的出台等于承认了进场费的合法性.本文从零售商的经营模式、赢利模式沿革出发,简要分析超市通道费是否妨碍市场公平竞争、是否导致物价上涨损害消费者利益等问题,并对通道费的分类及其法律调整进行探讨. 相似文献

城乡差距在改革开放前本就存在,加之改革开放中城乡发展速度的明显差异,随着改革的深入,城乡差距凸显。要想消除城乡差距,必须城乡统筹发展。但城乡差距不是短期能够消除的,城乡统筹发展需要始终坚持。为了尽快消除城乡差距,使城乡统筹发展落到实处,必须规定一些硬性指标,同时,必须从制度层面抑制政府官员的城市偏好。 相似文献

Following the lead of Reingen and Bearden (1983), this study examines the effectiveness of positive social labeling, particularly
in conjunction with other factors, as a means of influencing verbal and behavioral compliance in a multistage marketing survey
context. Such results offer a systematic extension to the labeling literature and provide further insight into labeling’s
role as a practicable method of shaping and stimulating respondent behavior. 相似文献

The effects of the service environment on affect and consumer perception of waiting time: An integrative review and research propositions 总被引:1,自引:0,他引:1
The management of buyers’ perceptions of waiting time by service businesses may be critical to customer satisfaction. Although
reducing actual waiting time is important, what managers view as a short time to wait may feel too long to customers. Relevant
literature from architecture, environmental psychology, psychology, physiology, operations management, sociology, and marketing
is integrated to build a conceptual model of how the service environment may influence affect and, in turn, waiting time perception.
Based on this model, propositions about how specific service environment elements (e.g., lighting, color, temperature) may
influence affect and time perception are presented. Finally, a research agenda and implications for service facility design
are proposed.

This article examines the link between recovery time and customer compensation expectations for service failures that cannot be immediately redressed. First, we show that the relationship between recovery time and compensation expectations is nonlinear. Initially, in a recovery time zone of tolerance, compensation expectations do not increase. Beyond this zone, the relationship follows an inverted U-shape, such that compensation expectations first increase but decrease in the long run. Second, our results show that long recovery times are accompanied by additional negative effects, including lower satisfaction with the recovery and negative word of mouth, so postponing service recovery represents a poor option. Third, relationship strength functions as a moderator. First-time customers expect higher compensation earlier; relational customers display a recovery time zone of tolerance but claim considerably higher compensations afterwards. Fourth, communication initiatives like the separate provision of status updates or an explanation may limit increases in compensation expectations over time. Still, their joint usage creates a “too-much-of-a-good-thing” effect, suggesting that if the usage of communication initiatives is taken too far it may lead to negative outcomes such as increasing compensation expectations. 相似文献
