Examining Trends of Criteria Air Pollutants: Are the Effects of Governmental Intervention Transitory? 总被引:1,自引:0,他引:1
Despite its growth in other areas of economics,time series econometric methods have not beenwidespread in the area of environmental andresource economics. We illustrate one use oftime series methods by examining the time pathof US nitrogen oxide (NOx) emission dataover the period 1900–1994. The analysishighlights that proper time series methods canaid in optimal regulatory policy as well asdeveloping empirical verification of theoriesput forth to explain economic phenomena. Inaddition, several interesting results emerge. First, we find that the emissions seriescontains both a permanent and random component. Second, if one attributed all of the emissionsreductions to regulatory policy, interventionanalysis suggests that the 1970 Clean Air Act(CAA) did not merely have transitory effects,but permanently influenced the NOxemission path. In terms of total regulatoryimpact, an upper bound on the emissions saveddue to the 1970 CAA is in the range of27%–48%. 相似文献

This paper examines the predictability of realized volatility measures (RVM), especially the realized signed jumps (RSJ), on future volatility and returns. We confirm the existence of volatility persistence and future volatility is more strongly related to the volatility of past positive returns than to that of negative returns in the cryptocurrency market. RSJ-sorted cryptocurrency portfolios yield statistically and economically significant differences in the subsequent portfolio returns. After controlling for cryptocurrency market characteristics and existing risk factors, the differences remain significant. The investor attention explains the predictability of realized jump risk in future cryptocurrency returns. 相似文献

The thesis resulting from the research on the "costs-effects" relation is the principle of economic efficiency of defence capabilities. At first glance, the arguments in this direction are well-known and popular in crisis situations of various nature, including the current financial and economic crisis in the country, and the question about the cost of public welfare-security and defence is debatable. This cost is manifested through the defence capabilities of a country. In the new security environment, the compilation of a national defence strategy is a priority of the Defence Ministry, which has more and more limited resources. This means that they should be treated as an economic activity. An economic activity is considered as any purposeful activity, allocating and combining scarce resources among alternatives, making it possible to maximize the outcomes and minimize costs. The ratio between the costs and benefits of a given resource or combination of resources to achieve a pre-defined objective is pushed to the forefront and the rationalization of management decisions is based on it. This necessitates a cost effectiveness analysis, hence the evaluation of the outcomes (benefits) is manifested in the "cost-effect (benefit)" analysis. Defence as a product has the basic features of any commodity or service, i.e. it is designed for exchange, is useful, and meets certain needs. But due to the fact that it meets very specific needs (,preservation of the territorial integrity of the country and improving its national security), it is distinguished by certain features which may be summarized as follows: collectivity of production and consumption of defence as a product necessary to the public, expressed by its consumption indivisibility; lack of market valuation of the price of defence as a product upon its consumption (as a monetary expression of its value); the usefulness of defence as a product is reflected in its capacity to meet the system's needs for security and defence, which dete 相似文献

The purpose of this paper is to analyze and compare the results of applying classical and Bayesian methods to testing for a unit root in time series with a single endogenous structural break. We utilize a data set of macroeconomic time series for the Mexican economy similar to the Nelson–Plosser one. Under both approaches, we make use of innovational outlier models allowing for an unknown break in the trend function. Classical inference relies on bootstrapped critical values, in order to make inference comparable to the finite sample Bayesian one. Results from both approaches are discussed and compared. 相似文献

The current research attempts to investigate the use of the two sources of dealers' soft channel power (i.e., expert power and referent power) as a means of achieving three desirable channel relationship outcomes in Zimbabwe's channel of distribution system. The field study is conducted in Harare and Chitungwiza, and research data are collected from 447 small and medium-size enterprise (SME) manufacturers. Dealers' expert power and referent power are found to be important sources of channel power that positively influence SME manufacturers' trust, relationship commitment, and relationship satisfaction. It is concluded that managers in dealers' firms can improve their channel relationships with SME manfacturers if they acquire or enhance their expert power and referent power. 相似文献
