Some empirical evidence suggests that the expected real interest and expected inflation rates are negatively correlated. This hypothesis of negative correlation is sometimes known as the Mundell‐Tobin hypothesis. In this article we reinvestigate this negative relation from a long‐term point of view using cointegration analysis. The data on the historical interest rate on T‐bills and the inflation rate indicate that the Mundell‐Tobin hypothesis does not hold in the long run for the United States, the United Kingdom, and Canada. We also obtain similar results using the real interest rate on index‐linked gilt traded in the United Kingdom. 相似文献

This study aims to develop a productivity index which takes into account the multidimensional characteristics of productivities. Our multidimensional productivity index (MPI) not only measures individual productivities of economic resources but also evaluate productivity enhancing general capacities of economy. Individual productivity indices such as labor productivity are limited because they do not consider the factors, such as the globalization of economies and the market and institutional variables, that could have profound impacts on productivity. The multidimensional Productivity Index (MPI) is measured for 60 countries including 23 OECD countries and 10 Asian countries. Our methodology employs the concept of technical efficiency that allows us to measure the extent to which institutional and market factors contribute to the economic performance. Our findings indicate that standard productivity measures such as labor productivity may overestimate the overall productivity differences across the economies. 相似文献

The present study examined financial market risk exposure of human capital returns, which are represented by the returns to education, using panel data for Korea. Overall, financial market shocks seem to be irrelevant to returns to education. However, when we divide a financial market shock into cash flow news and discount rate news leading to a negative risk premium, returns to education increase after positive news about future cash flows and unexpected increases in discount rates Therefore, the risk exposure to cash flow shocks is offset by the exposure to discount rate shocks. The returns to education of low‐income workers were significantly exposed to the cash flow risk as compared to those with a high income, but they were offset by the positive correlation to discount rate shocks. In contrast, considering the gap between generations, the old generation was not only less exposed to the cash flow risk compared to the young generation regarding returns to education but also positively correlated with the discount rate shock, resulting in less exposure to financial market risks. 相似文献

Previous studies that compare a uniform money with separate monies used models in which money is the only asset and in which
individuals hold either zero or one unit of money. Here, the comparison is made using a model in which money coexists with
a higher-return asset and in which individuals are permitted to hold richer portfolios of assets. The results show that a
general conclusion is not possible. A uniform money has a higher expected utility than do separate monies in many examples.
However, when the discount on bonds and uncertainty about the nationality of the trading partner are sufficiently high, then
there are examples in which separate monies are better.

AbstractOver the past two decades, there has been a proliferation of research on human resource management (HRM) in Chinese state-owned enterprises (SOEs) as a result of the wide-reaching state-sector reform of the late 1980s. This article aims to provide a systematic review of literature on this topic and capture the nature of HRM in Chinese SOEs, both in research and practice. The article draws on 178 studies from 43 English academic journals over a period of 25?years (1993–2017). In analysing this literature and by taking stock of theoretical frameworks, research methods, themes and analysis of academic articles in this area, we have gained a number of insights. The study has found that the research methods used have shifted from qualitative and interpretive methodology toward quantitative and sophisticated modelling. A further insight is that there has been a relatively heavy reliance on institutional theory in the earlier studies reviewed, and since then a switch towards organizational behaviour perspectives. The level of analysis has moved from macro to micro level and thematic foci have become more diverse and complex. We highlight a number of avenues, theoretical and empirical, for future studies in this field. 相似文献

The design of reverse logistics network has attracted growing attention with the stringent pressures from environmental and social requirements. In general, decisions about reverse logistics network configurations are made on a long-term basis and factors influencing such reverse logistics network design may also vary over time. This paper proposes dynamic location and allocation models to cope with such issues. A two-stage stochastic programming model is further developed by which a deterministic model for multiperiod reverse logistics network design can be extended to account for the uncertainties. A solution approach integrating a recently proposed sampling method with a heuristic algorithm is also proposed in this research. A numerical experiment is presented to demonstrate the significance of the developed stochastic model as well as the efficiency of the proposed solution method. 相似文献

Mobile tourism shopping is an emerging market, but there is little theoretically based research on the topic. This study investigates the impact of motivations (value, enjoyment, time saving and mobility) on consumer satisfaction by applying contingency and task–technology fit theories in the mobile tourism shopping context. The results show that value and enjoyment have significant effects on satisfaction. Use context is found to have a full mediating role between time saving and satisfaction as well as between mobility and satisfaction. This study offers theoretical and practical contributions to the tourism literature and mobile tourism industry. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

The contextual nature of the predictive power of statistically-based quarterly earnings models 总被引:2,自引:2,他引:0
We present new empirical evidence on the contextual nature of the predictive power of five statistically-based quarterly earnings
expectation models evaluated on a holdout period spanning the twelve quarters from 2000–2002. In marked contrast to extant
time-series work, the random walk with drift (RWD) model provides significantly more accurate pooled, one-step-ahead quarterly
earnings predictions for a sample of high-technology firms (n = 202). In similar predictive comparisons, the Griffin-Watts (GW) ARIMA model provides significantly more accurate quarterly
earnings predictions for a sample of regulated firms (n = 218). Finally, the RWD and GW ARIMA models jointly dominate the other expectation models (i.e., seasonal random walk with
drift, the Brown-Rozeff (BR) and Foster (F) ARIMA models) for a default sample of firms (n = 796). We provide supplementary analyses that document the: (1) increased frequency of the number of loss quarters experienced
by our sample firms in the holdout period (2000–2002) vis-à-vis the identification period (1990–1999); (2) reduced levels
of earnings persistence for our sample firms relative to earnings persistence factors computed by Baginski et al. (2003) during earlier time periods (1970s–1980s); (3) relative impact on the predictive ability of the five expectation models
conditioned upon the extent of analyst coverage of sample firms (i.e., no coverage, moderate coverage, and extensive coverage);
and (4) sensitivity of predictive performance across subsets of regulated firms with the BR ARIMA model providing the most
accurate predictions for utilities (n = 87) while the RWD model is superior for financial institutions (n = 131).

Context matters: How existing sectors and competing technologies affect the prospects of the Swiss Bio-SNG innovation system 总被引:1,自引:0,他引:1

Emerging technological fields are affected by developments in their broader context. This article proposes a differentiation of context structures as a crucial step in the analysis of technological innovation systems. A thorough context analysis, so the argument, is essential for understanding the pace and direction of technology development and the prospects of an emerging technological innovation system. Empirical insights are provided for Bio-SNG, a technology in an early stage of development. The article discusses the conditions under which actors from different sectors (forestry, wood industry, and energy supply) may play a role in the emerging field. It is shown that Bio-SNG is likely to become a victim of the recent boom in wood-to-energy technologies that has favored investments in more mature but technologically inferior alternatives. The case provides lessons for policy making as it highlights how effective support schemes might foster a lock-in into technologies that are readily available. 相似文献
