We estimate a target zone model for three ERM exchange rates for 1983–6 and 1987–91 by the method of simulated moments, taking account of the continuous time specification by using daily data with the interruptions of holidays and weekends. Specification tests are unable to reject the model. The estimates imply, however, an essentially linear relationship between the exchange rate and the fundamentals, with a very limited 'honeymoon effect'. Using Monte Carlo simulations, calibrated on the estimates, we find that standard tests for mean reversion of the exchange rate would largely reject the target zone model when, in fact, it held. 相似文献

We seek to understand the ever-increasing push towards the international harmonization of accounting standards and particularly the inexorable rise of standards produced by the International Accounting Standards Board (IASB). While the primary justifications for the increasing recognition given to these standards (IFRS) are economic, we question whether the empirical evidence to date has yielded convincing support for these arguments. We therefore offer an alternative explanation for the origin and diffusion of IFRS that incorporates social and political factors. Outsourcing the manufacture of accounting standards to a single private agency appears to be a rational, lower cost option – lowering both economic and political costs for individual states as long as they continue to retain residual decision rights with respect to the adoption of IFRS. However, such outsourcing must also be perceived to be legitimate. IFRS confer institutionalized legitimacy because they possess three characteristics required of a technology for global governance. These are sponsorship by powerful interest groups/regulators, internationality and plasticity. We therefore conclude that the widespread diffusion today of IFRS can at best be only partially explained as an economically rational phenomenon. Rather, the demand for legitimate action in the face of tightly coupled and complex global markets is at least equally important in generating support for IFRS. 相似文献

Understanding longitudinal trends in the processing of carbon in rivers represents a much conceptualised, but infrequently tested, issue in aquatic ecology. In this study, we conducted concurrent longitudinal examinations of three very different rivers in eastern Australia to determine whether general principles in river functioning exist across broad geographic and hydrologic scales. Specifically, we examined trends in ambient basic water chemistry, nutrient concentrations, dissolved organic carbon (DOC), extracellular enzymes and food web structure and functioning and conducted bioassays to examine the degree to which DOC and nutrients limit heterotrophic bacterial respiration. These parameters revealed striking similarities across all sites. For metazoan communities, stable isotope analysis showed that algal carbon was the dominant basal resource utilised by consumers in all three rivers, suggesting that in‐stream primary producers strongly underpin trophic pathways regardless of the position within a catchment or catchment condition. Analyses of extracellular enzymes revealed that microbial communities are actively utilising DOC at all sites. In fact, heterotrophic microbial respiration was strongly limited by DOC at all sites, with nutrient additions resulting in only relatively minor increases in respiration. Ultimately, this study demonstrates that DOC and algal carbon are critically important drivers of ecosystem processes in Australian riverine ecosystems. Furthermore, across all of our sites and rivers, ambient nutrient concentrations did not influence carbon processing. The consistent longitudinal trends in river function identified in this study provide useful insights for catchment managers and modellers with respect to identifiying key principles that underpin ecosystem functioning in Australian rivers.

While the marketplace potential of the elderly segment is tremendous, research with regard to what influences the elderly’s
patronage behavior has, to date, been inconclusive. This article attempts to determine the effect lack of transportation mobility
has on various patronage behaviors. The research reported here is based on a large national smaple of the elderly and incorporates
the factors suggested by previous research. The study shows mobility is not a significant influence on the type of retail
store frequented, but can influence switching patronage between stores of a given type. Additionally, it was found that mobility
is related to the elderly’s psychographic profiles, convenience needs, and information source usage. 相似文献

In this exploratory study of union formation in the Indian call centre/business process outsourcing sector, the authors draw upon evidence from the first detailed survey of members of the recently formed UNITES, and from extensive interviews. This paper engages with mobilisation theory and analyses of trade union formation. 相似文献

The problem of long-range planning and investment project evaluation is complicated by the presence of multiple conflicting goals measured in incommensurable units, indivisibility of alternative projects, and the desire of management to consider mutually exclusive marketing-pricing strategies. The model proposed in this study attempts to allow for these complexities through the use of integer goal programming. It is the hope of the authors that this model will provide management with an additional decision-making tool for implementation of multiple corporate objectives. 相似文献

A computationally feasible method for the full information maximum-likelihood estimation of models with rational expectations is described in this paper. The stochastic simulation of such models is also described. The methods discussed in this paper should open the way for many more tests of the rational expectations hypothesis within macroeconomic models. 相似文献
