The rate schedules for services provided by regulated industries are often not defined in terms of simple per-unit charges but as multipart tariffs. For example, in the case of block price rates, the rate parameters are the definition of the block limits and the per-unit charges in each block. The analysis of these rates is complicated by the fact that most econometric models provide only per-unit or marginal-cost-based elasticities. This paper presents a technique for determining the rate schedule elasticities from elasticities for functions of the rate schedule parameters such as per-unit price elasticities. Also presented are methods for determining elasticities for combinations of service characteristics and the price schedule parameter elasticities for an entire service market. Examples are given for block water rates and Hopkinson and time-of-day electricity rates. 相似文献

Standard procedures for extractingwillingness-to-pay (WTP) from dichotomouschoice CV questionnaires rely heavily uponparametric assumptions regarding thedistribution and form of WTP in the sampledpopulation. However, theory provides littleguidance regarding which parametricspecification to use and the resulting WTPestimates can be sensitive to the selectionsmade. Here we compare and contrast severalparametric and semi-nonparametric estimatorsthat have been proposed in the literature,examining the sensitivity of the resulting WTPestimates to the underlying distribution ofpreferences and the estimation procedureemployed. 相似文献

A highly integrated area like the EMU features a large amount of interactions between the participating countries. In this context the interactions of monetary and fiscal policies are a crucial issue. This paper focuses on how coalitions among policymakers are formed and discusses their effects on the stabilization of output and price. We emphasize the role played by the institutional design of cooperation forums (as, e.g., the ECOFIN). If the coalition formation game is played without communication among the policymakers, full cooperation is an unlikely outcome. On the other hand, if policymakers can communicate, full cooperation becomes a possible equilibrium, while the complete non-cooperative solution is, in general, not a stable equilibrium. This supports the view that institutions for discussions can play a crucial role in achieving international cooperation even when these institutions are not endowed with enforcement powers.revised version received August 1, 2003 相似文献

The market effects of alternative housing payment formulas are analyzed and compared for a metropolitan housing market using measures of efficiency and distributional equity. The effects of “earmarking” allowance payments are considered. Estimated market effects are based on a model of housing market behavior over a 10-year period. The results differ significantly from what one might anticipate based on demand analyses of individual behavior. “Housing gap” formulas perform better than percent-of-rent formulas. Certain characteristics of the housing market together with particular income redistribution effects of the allowances appear to explain the market behavior. 相似文献

Bootstrapping Confidence Intervals for Linear Programming Efficiency Scores: With an Illustration Using Italian Banking Data 总被引:2,自引:1,他引:1
This article suggests a method for introducing a stochastic element into Farrell measures of technical efficiency as calculated via linear programming techniques. Specifically, a bootstrap of the original efficiency scores is performed to derive confidence intervals and a measure of bias for the scores. The bootstrap generates these measures of statistical precision for the nonstochastic efficiency measures by using computational power to derive empirical distributions for the efficiency measures. 相似文献

This paper notes that Gini's concept of Transvariazione corresponds to the idea of overlapping of distributions. It shows that this concept is implicit in some measures of income inequality such as the Pietra and Gini Index and is at the basis of various measures of distance between distributions. An empirical illustration is provided, based on Israeli data for the period 1978–1994. 相似文献

Households save income for various reasons, including the need to plan for the future, the intention to leave a bequest, and
the desire to guard against unforeseen expenditures and income fluctuations. Although it is widely believed that prudent individuals
engage in precautionary saving, the extent of such saving is not well understood. This paper develops a model of saving with
an explicit role for the Leland-Kimball measure of prudence. Estimation of the model using household-level data from Italy
suggests an average value of relative prudence near 4 or 5, with approximately 15 to 36 percent of total saving being precautionary.

This research provides a comprehensive historical analysis of articles published in The Journal of Risk and Insurance over the 75‐year period from 1932 to 2006. Historical statistics are provided including the number of articles, number of authors per article, geographic location of contributors, leading contributors, author affiliation (industry or academic), the proportion of articles that are theoretical and empirical, and topics covered. Statistics relating to the entire 75‐year period are provided as well as breakdowns by decade. The results indicate that the contributors to The Journal of Risk and Insurance have become more international over time, average article length and average number of authors per article have increased over time, and empirical articles appear more frequently than theoretical articles. 相似文献

The discovery of the dynamics of a time series requires construction of the transition density. We explain why 1-point densities and scaling exponents cannot determine the class of stochastic dynamics. Time series require some sort of underlying statistical regularity to provide a basis for analysis, and we construct an exhaustive list of such tests. The condition for stationary increments, not scaling, determines the existence of long time pair autocorrelations. We conjecture that for a selfsimilar process neither the pair correlations 〈x(t)x(s)〉 nor the 2-point density scales in both times t and s except in a pathological case, and give examples using three well-known Gaussian processes. An incorrect assumption of stationary increments can generate spurious stylized facts, including fat tails. When a sliding window is applied to nonstationary, uncorrelated increments then a Hurst exponent Hs = 1 / 2 is generated by that procedure even if the underlying model scales with a Hurst exponent H ≠ 1/2. We explain how this occurs dynamically. The nonstationarity arises from systematic unevenness in the traders' behavior in real time. Spurious stylized facts arise mathematically from using a log increment with a ‘sliding window’ to read the series. In addition, we show that nonstationary processes are generally not globally transformable to stationary ones. We also present a more detailed explanation of our recent FX data analysis and modeling. 相似文献

A comparative analysis of proxies for an optimal leverage ratio 总被引:1,自引:0,他引:1
Previous studies that test the tradeoff theory commonly use one of the following debt ratio measures to proxy for a firm's hypothesized optimal ratio: firm's time-series mean leverage, moving average leverage based on a firm's historical debt ratios, industry median leverage, and predicted leverage ratio based on cross-sectional regressions. We find that these alternative proxies yield results that are significantly different from each other. Further, regression results of models that use the optimum target leverage and the conclusions drawn from the findings are sensitive to the model's proxy. Of the proxies that are commonly used in the literature, the moving average debt measure exhibits characteristics that are most consistent with the theoretical optimal leverage ratio. 相似文献
