Consistent estimation in the bilinear multivariate errors-in-variables model

A bilinear multivariate errors-in-variables model is considered. It corresponds to an overdetermined set of linear equations AXB=C, A∈ℝ^m×n, B∈ℝ^p×q, in which the data A, B, C are perturbed by errors. The total least squares estimator is inconsistent in this case.  An adjusted least squares estimator is constructed, which converges to the true value X, as m →∞, q →∞. A small sample modification of the estimator is presented, which is more stable for small m and q and is asymptotically equivalent to the adjusted least squares estimator. The theoretical results are confirmed by a simulation study. Acknowledgements. We thank two anonymous reviewers for their suggestions and corrections.? A.

Multilateral Comparison of Cost Structures in the Input–Output Tables of Japan,the US and West Germany

This paper presents a multilateral comparison of relative levels and structures of costs of production in Japan, the US and West Germany. The analysis is carried out by using harmonized input–output tables, which are converted at US prices by using adjusted sectoral purchasing power parities. A new accounting methodology is derived from recent developments of index number theory, whereas the chosen multilateral comparison procedure gives results that are invariant with respect to the order of the pairs of countries examined.     

企业长期激励机制创新

长期激励机制匮乏问题一直是我国理论界和实业界最为关注的核心问题。指出目前在我国实行的长期激励措施的不足,提出了以“股息期权”,代替“股票期权”的激励方案,从而有效解决了我国目前的资本市场和法律法规对于“长期激励形式”的约束,可以为现阶段企业管理者进行薪酬激励机制设计时提供重要的参考和借鉴。     

Trade matters except to war neighbors: The international stock market reaction to 2022 Russia’s invasion of Ukraine

We investigate the role of international trade and proximity to war in international stock markets during the invasion of Ukraine by employing DiD designs and panel data comprising 70 stock markets. We find that differences in trade exposure to warring countries (trade effect) have a substantial and negative impact on non-European equity markets but are irrelevant for European markets. In contrast, differences in the distance to warring countries (proximity effect) have a significant and negative impact on European markets but have no bearing on non-European markets. We find that the relevance of rent from mineral, natural gas, and oil resources and the relevance of metals, ores, and fuels in exports operate as mitigators of the trade effect. Our paper provides valuable empirical evidence regarding the importance of mitigating the vulnerability of financial markets to international trade when a major war breaks out.     

Economic Valuation of Health for Environmental Policy: Comparing Alternative Approaches. Introduction and Overview

Protecting human health is a primary goal of environmental policy and economic evaluation of health can help policy-makers judge the relative worth of alternative actions. Economists use two distinct approaches in normatively evaluating health. Whereas environmental economists use benefit-cost analysis supported by monetary valuation in terms of willingness-to-pay, health economists evaluate interventions based on cost-effectiveness or cost-utility analysis (CEA), using quality-adjusted life-years (QALY) or similar indexes. This paper provides background on the controversy about the relative merits of these approaches and introduces the remaining papers in the special issue. These papers (with one exception) were presented at a conference sponsored by the Department of Economics at the University of Central Florida with support from the US Environmental Protection Agency. Although CEA might not lead to substantially different implications for environmental policy than benefit-cost analysis, and QALY may provide a benefit transfer tool to fill gaps in the morbidity valuation literature, the papers in this issue raise serious concerns about the suitability of QALY-based CEA for environmental regulatory analysis. QALY does not in general appropriately represent individual preferences for health and CEA is neither independent of income distribution nor adequate to assess efficiency.     

Natural resource accounting for Indian states — Illustrating the case of forest resources

Our main objective is to set out and apply a SEEA-based methodology to reflect the true value of forest resources in India's national and state accounts. We establish that a “top-down” approach using available national databases is both feasible and desirable from a policy perspective. In this paper, we address four components of value creation in forests: timber production, carbon storage, fuelwood usage, and the harvesting of non-timber forest products. The results of our analysis suggest that prevailing measures of national income in India underestimate the contribution of forests to income. The income accounts of the Northeastern states in particular are significantly understated by these traditional (GDP/GSDP) measures. We are also able to identify some states which performed poorly in the context of our sustainability framework, reflecting natural capital losses due to degradation and deforestation. Our results highlight the need to integrate natural resource accounting into the national accounting framework in order to generate appropriate signals for sustainable forest management and for the conservation of forest resources which are widely used by the poor in India, as well as being significant stores of national wealth.     

分红保险合同红利负债的确认与计量研究

Double Dividend with Involuntary Unemployment: Efficiency and Intergenerational Equity

This paper analyzes the double dividend and distributional issues within an overlapping generations model framework with involuntary unemployment. We characterize the necessary conditions needed to obtain a double dividend, when the revenue of the environmental tax is recycled by a variation of the labor tax rate. We show that an employment dividend may occur without any efficiency dividend and that the young generation is not always harmed by the fiscal reform, even without any intergenerational transfers. Therefore, three dividends (environmental, efficiency and intergenerational equity) can occur simultaneously.

INTEREG: A Twenty-region Input–Output Model for Italy

Since the regional scale turns out to be the scale at which fiscal devolution is likely to be accomplished in Italy, and that at which trade and growth interdependencies as well as regional convergence can be most conveniently investigated, a new 20-region input–output model for Italy seems to be a useful tool of analysis. Although various regional and interregional models have been constructed since the 1950s, none has been implemented for the whole system of 20 Italian administrative regions considered in their tight mutual dependence; also, the pool approach has not been greatly favoured, even in situations where direct information on regional trade is lacking. The main purpose of this paper is to report on the structure of the model, the rather complex procedure used in the model construction and the adopted solution technique. Some space is devoted to the problems encountered in handling regional trade endogenously in an input–output setting and to a comparison between the pool approach, used in the Italian model, and other current techniques. The paper also reports on some preliminary results regarding the regional impact of fiscal policy.
