The paper develops a Post Keynesian macroeconomic model which discusses the conditions that lead to an external debt crisis in a small developing economy fully integrated to global goods and financial markets. The focus is on how policy rules affect the stability of the economy. Two kinds of policy rules are discussed, namely inflation target and real exchange rate target, implemented through an interest rate operation procedure (IROP). It is argued that in both cases the evolution of the real exchange rate should be closely monitored to avoid external instability. It is also suggested that a real exchange rate target may be more effective to stabilize the economy if there is a strong tendency towards the equality of the foreign and domestic real interest rates. 相似文献

The growing complexity of the global business environment is leading innovative firms to demand further external counselling to better handle rapid change and increasing uncertainty. Likewise, the implementation of new information systems is usually carried out with the help of external advisors. This paper examines whether the provision of consulting services undermines audit reporting quality by testing for an association between advisory services and audit reporting. A cross-sectional logistic regression is estimated to test the relationship between consulting fees and the audit outcome. The evidence suggests that there is no statistically significant association between non-audit fees and audit outcome. This finding is consistent with the idea that audit reporting quality is not impaired by the provision of consulting services. 相似文献

In a linear rational expectations two–country model, using an aggregate demand, aggregate supply framework, we analyse the effects of the adoption of an inflation–targeting regime on exchange rate volatility and the possible scope for policy coordination. This analysis is conducted using optimized interest rate policy rules within a calibrated model. Rules for interest rates that respond either to exchange rates or to portfolio shocks give improved performance and permit gains from international coordination. Optimized Taylor rules perform relatively well. 相似文献

This paper contains results on local and global stability of n-sector growth models when utility is discounted mostly for small rates of discount. It is well known that when future utility is not discounted one can prove precise results about optimal steady states (OSS's) under fairly general assumptions. In particular, existence, uniqueness, and turnpike properties have been established by several authors. The counter examples presented by Kurz, Sutherland, and Weitzman, however, show that when utility is discounted, additional assumptions are required to obtain turnpike results. In general, it would be interesting to know how the submanifolds of stability change as δ changes. One hopes that certain conditions on the utility function would be sufficient to “classify” the submanifolds of stability and instability. Such a question is apparently very difficult to answer, but we think that the results obtained here will help in this task.The proof that the turnpike theorem holds for discount factors near one is divided in two parts. First, we prove that optimal paths “visit” neighborhoods of the modified OSS's. Then, we prove that local stability holds for such neighborhoods.In order to show this fact, we must prove that the local “stable manifold” varies continuously with the discount factor. This roundabout method is necessary since our problem is similar to proving uniform continuity with respect to a parameter of solutions of a differential equation in a noncompact interval of time.Other problems analyzed here include uniqueness and continuity of OSS's. We also discuss the relation between the saddle-point property and the local stability of infinite horizon optimal growth paths. 相似文献

The paper undertakes a dynamic analysis for service quality in the electricity distribution in Brazil between 2010 and 2014 based on Malmquist indexes constructed upon Data Envelopment Analysis (DEA) distance functions. The motivation for the less usual consideration of efficiency frontiers for service quality, that does not rely on traditional inputs and outputs but rather on quality indicators, builds on previous static applications in the context of telecommunications. The analysis considers undesirable technical indicators for quality as inputs and desirable consumer satisfaction indicators for quality as outputs in the efficiency frontier analysis. The bootstrap‐corrected Malmquist indexes indicated service quality deterioration in 38.1 per cent, quality stagnation in 40.5 per cent and quality improvement only in 21.4 per cent of the cases. When one decomposes the Malmquist index, the evidence does not suggest relevant frontier shifts and indicates a dominant role for the catch‐up effect. Finally, Malmquist indexes are regressed against variables that may portray heterogeneities, such as firm size, service area, density, ownership and regional dummies in terms of a well‐known two‐stage procedure. The mostly weak significance results reinforce the plausibility of the initial analysis. 相似文献

This paper examines the simultaneous impact of demand variability, demand skew, and configuration capacity on customer service in a configure‐to‐order environment. Simulation is done in ARENA and data are analyzed using ANOVA and MANOVA. The findings indicate that the factors studied have differential impact on performance both individually and interactively. 相似文献
