The main purpose of the present study is to analyse the emission dynamics of atmospheric and water pollutants in Russia and cost of their removal in the 1980s and early 1990s, and to forecast them by means of a Dynamic Input–Output Model according to different scenarios of future economic development till 1998. Main results of the work are:– methodological principles have been elaborated for singling out the environmental protection sector within the national economy;– a method has been offered for including the ecological block into a Dynamic Input–Output Model of the Russian economy;– a method of data preparation has been elaborated for the ecological block of the above-named model, the data base which characterizes the ecological situation in Russia has been formed and analysed;– calculations for 1994–1998 have been executed for forecasting the economic and ecological development of Russia using the above-mentioned model and the results obtained have been analysed. The results showed that if the existing tendencies towards low environmental protection capital costs remain the same, then the negative environmental impact will increase. In order to implement ecological programs and international agreements, to increase the proportion of removed pollutants, it is necessary to increase substantially expenditures on purifying water and air resources. The proportion of environmental protection investments in the total amount of the national economy capital costs should increase by up to 12–40% according to different scenarios of the economic development and different purposes of the environmental protection policy. 相似文献

Federally regulated or insured lenders in the United States are mandated to require flood insurance on properties that are located in areas at high risk of flooding. Despite the existence of this mandatory flood insurance requirement, take‐up rates for flood insurance have been low, and the federal government's exposure to uninsured property losses from flooding remains substantial. Meanwhile, the value of capital at risk varies significantly with flood events and changing risk perceptions, which necessitates mechanisms that stabilize these dynamics. In this article we discuss how a scenario of complete insurance uptake, under various risk attitudes, affects the value of properties in the 100‐year and 500‐year flood zones. Our results indicate that an increase in flood insurance uptake may provide such a mechanism by lowering the value of capital at risk in the flood zone consistently, independent of homeowners' risk attitudes. We apply an empirical adaptive agent‐based model to examine the capitalization of insurance costs, risk premiums, and their interaction in housing prices. Our approach combines widely‐used empirical hedonic analysis with the computational economic framework. We highlight the usefulness of our method in capturing the marginal implicit price of homeowners' preferences that may change over time and separately assess the effect of various factors and policies on property values, illustrating the agent‐based modeling as a valuable complement to traditional hedonic analysis. 相似文献

The formation of a new venture includes initial choices that affect the process of start‐up. Primary among these decisions is the choice of location whether to start from home or from an away location. This paper examines the impact of initial firm location choices and aspirations of the entrepreneur on the resource assembly process and the likelihood of first sale. Results show that home‐based businesses assemble different types of resources from their away‐based counterparts. Higher aspirations were associated with greater accumulation of organizational resources. The combined influence of location and aspirations showed that home‐based firms with high aspirations were less likely to achieve first sale. A post hoc analysis examined these affects within a subgroup of service firms and confirmed the previous results. This study suggests that in the initial stages of the new venture, there are processes and routines that home‐based businesses engage in that lead them to achieve first sales in a timelier manner than those businesses that are located away from home. Furthermore, high aspirations are associated with greater scale of organizational resources but not necessarily with achievement of sales. Implications are discussed. 相似文献

This article investigates the cyclical behavior of the degree of plant utilization, inventories, order book level, and confidence
climate index data (taken from Italian Business tendency surveys). It first analyzes the co-movements between the survey indicators
and the Italian business cycle by performing a sensitivity analysis with respect to the reference business cycle and to the
filtering technique, using time and frequency domain methods. It then discusses the ability of such indicators to predict
business cycles and their importance with respect to other standard national accounts data. The results of bivariate analysis
show that, whereas the degrees of plant utilization, confidence climate and order book level are procyclical, inventories
appear to be countercyclical with respect to both the industrial sector and the whole-economy business cycle. Spectral analysis
suggests that the high-frequency elements of the survey data tend to lead those of the business-cycle estimates obtained from
the national income accounts. The choice of filtering technique affects the results, especially in the magnitude of co-movements.
The forecasting exercise reveals the usefulness of such data in forecasting the real economy in the short run. 相似文献

This paper examines jobs in the information society and the new economy, taking as its focus the call center industry. More
specifically, the study analyzes the degree of variability of the quality of call center jobs. In order to achieve this objective,
an index of job quality is generated, and an empirical analysis of the characteristics of jobs in call centers is carried
out. This allows us to determine the level and variability of quality of jobs in this sector and to establish whether the
reality of these jobs is as good as the forecasts for work in the new economy.

We consider an insurance company whose surplus is represented by the classical Cramer-Lundberg process. The company can invest its surplus in a risk-free asset and in a risky asset, governed by the Black-Scholes equation. There is a constraint that the insurance company can only invest in the risky asset at a limited leveraging level; more precisely, when purchasing, the ratio of the investment amount in the risky asset to the surplus level is no more than a; and when short-selling, the proportion of the proceeds from the short-selling to the surplus level is no more than b. The objective is to find an optimal investment policy that minimizes the probability of ruin. The minimal ruin probability as a function of the initial surplus is characterized by a classical solution to the corresponding Hamilton-Jacobi-Bellman (HJB) equation. We study the optimal control policy and its properties. The interrelation between the parameters of the model plays a crucial role in the qualitative behavior of the optimal policy. For example, for some ratios between a and b, quite unusual and at first ostensibly counterintuitive policies may appear, like short-selling a stock with a higher rate of return to earn lower interest, or borrowing at a higher rate to invest in a stock with lower rate of return. This is in sharp contrast with the unrestricted case, first studied in Hipp and Plum, or with the case of no short-selling and no borrowing studied in Azcue and Muler. 相似文献

This article examines the profitability of dual moving average crossover (DMAC) trading strategies in the Russian stock market over the 2003–12 period. It contributes to the existing technical analysis (TA) literature by testing, for the first time, the applicability of ordered weighted moving averages (OWMA) as an alternative calculation basis for determining DMACs. In addition, this article provides the first comprehensive performance comparison of DMAC trading rules in the stock market that is known as one of the most volatile markets in the world. The results show that the best trading strategies of the in-sample period can also outperform their benchmark portfolio during the subsequent out-of-sample period. Moreover, the outperformance of the best DMAC strategies is mostly attributable to their superior performance during bearish periods and, particularly, during stock market crashes. 相似文献
