Testing for non-linear dependence in inter-war exchange rates   总被引:1,自引:0,他引:1  
Testing for Non-Linear Dependence in Inter-War Exchange Rates. — This paper tests weekly inter-war floating exchange rate data for the pound-dollar, pound-franc and pound-reichsmark for non-linearity. Initial tests reveal strong evidence of generic non-linearity in these series and indicate neglected non-linear structure in the residuals of linear representations. Attempts to model this structure using GARCH residual processes have only been partially successful. Thus, two parametric models of such non-linearity were estimated. Comparing the forecasts from these models shows the mean square forecast errors of linear-GARCH and bilinear models to be lower than those from linear forecasts for all series, and that SETAR model forecasts outperform all other models for the pound-dollar.  相似文献

The dynamic relationship linking the volatility of equity prices with “the news” and the expected path for monetary policy is investigated. Previous results that link the impact of the news about real activity to changes in current and future interest rates are employed in developing a positive link between changes in volatility and the news. Empirically, our results uncover a positive and statistically significant response of the CBOE volatility index, VIX, to unanticipated changes in employment, but not to inflation. Hence, agents' expectations for the policy response to news have an important influence on the expected volatility of stock prices. (JEL E44, E52)  相似文献

We determine when an unfettered auction will ensure the welfare‐maximizing allocation of a scarce input that enhances product quality and may reduce production costs. A supplier values the input for this “use value” and for its “foreclosure value,” because once the input is acquired, it is unavailable to rivals. An unfettered auction often ensures the welfare‐maximizing allocation of an input increment. However, it can fail to do so when the input would increase relatively rapidly the competitive position of a rival with a moderate competitive disadvantage. Bidder handicapping that ensures auctions generate welfare‐maximizing input allocations differ from standard handicapping policies.  相似文献

The results of this study indicated that consumers had a favorable attitude toward advertising by lawyers, though some specific differences were found between users and nonusers of legal services. The importance of consumer demographic characteristics and the appropriateness of advertising media were also examined. The major implication is that the traditional void in advertising activity by lawyers should now be reexamined.  相似文献

In the western world, and in the United States in particular, there has been an abundance of food, materials and fuel over the past several decades. However, many futurists suggest this condition will soon change and a wide range of scarcities will result. Conditions in underdeveloped countries suggest one probable reaction to shortages in hoarding. In light of the predicted shortages this paper (1) develops definition and conceptualization of what constitutes hoarding, and (2) examines the influence hoarding activities have on channel decisions. An overriding purpose of the paper is to generate interest and research into the topic before conditions necessitate that concern.  相似文献

This paper analyses the presence of financial constraint in the investment decisions of 367 Brazilian firms from 1997 to 2004, using a Bayesian econometric model with group-varying parameters. The motivation for this paper is the use of clustering techniques to group firms in a totally endogenous form. In order to classify the firms we used a hybrid clustering method, that is, hierarchical and non-hierarchical clustering techniques jointly. To estimate the parameters a Bayesian approach was considered. Prior distributions were assumed for the parameters, classifying the model in random or fixed effects. Ordinate predictive density criterion was used to select the model providing a better prediction. We tested thirty models and the better prediction considers the presence of 2 groups in the sample, assuming the fixed effect model with a Student t distribution with 20 degrees of freedom for the error. The results indicate robustness in the identification of financial constraint when the firms are classified by the clustering techniques.  相似文献

This paper explores the issue of sustainability at the macro scale employing multi-criteria decision aid (MCDA) methods. The incommensurability of values and the essentially multi-dimensional and dynamic nature of sustainability challenge the use of composite measurement indices. This determined the choice of MCDA methods. Austria was chosen as a case study, due to the wide availability of data, especially on indicators of strong sustainability. The structure of the multi-criteria problem comprised the evolution of different sustainability dimensions over time. The process for selecting criteria included a critical assessment of institutional sustainability agendas (UN, EU and Austrian Government) and theoretical recommendations.After an assessment of MCDA methods, the NAIADE method demonstrated the most suitable properties for sustainability assessment. The application of this outranking approach was undertaken in three separate settings: long-term from 1960 to 2003, medium-term, 1970-1995, and short-term, 1995-2003 with varying numbers of criteria. The response of results to the addition of evaluating criteria and periods was tested. The degree of credibility for accepting preference relations was also employed for sensitivity analysis.According to the results of long-term and medium-term assessments, especially in the weak sustainability setting, sustainable progress is taking place in Austria. In the short term, in the stronger sustainability setting and, especially as the number of criteria increases, more incomparable periods appear and trends are less determined. Moreover, it is shown how results crucially depend on the methodological choices.This is one of the first applications of the multi-criteria tools to the dynamic analysis of sustainability at the macro scale.  相似文献
