论会计事项的认定与会计确认

符合确认标准的会计事项是会计确认的对象,会计确认是会计事项进入财务会计系统的第一道关口,两者关系十分密切,本文对会计事项作了科学界定,并针对不同事项的认定说明其对会计确认对象、观点和时间的影响,为科学合理地确认会计事项提供了理论指导。

On the public provision of the performing arts

In this paper, we present a model in which the performing arts are modelled as congestible public goods. In accordance with empirical evidence, the production of seat capacity is assumed to be subject to fixed costs. We estimate the parameters of the model's demand and cost functions using German data. Using these estimates in a subsequent social choice analysis, we show that the current situation in the German performing arts sector is best described by a directorship that under the influence of a selfish theater lobby maximizes only the welfare of the spectators. Such an equilibrium, characterized by too low ticket prices and too large capacity, is most likely to establish if citizens have a very positive ex ante notion of the performing arts.     

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.     

Mean-variance hedging for interest rate models¶with stochastic volatility

The mean-variance hedging approach for pricing and hedging claims in incomplete markets was originally introduced for risky assets. The aim of this paper is to apply this approach to interest rate models in the presence of stochastic volatility, seen as a consequence of incomplete information. We fix a finite number of bonds such that the volatility matrix is invertible and provide an explicit formula for the density of the variance-optimal measure which is independent of the chosen times of maturity. Finally, we compute the mean-variance hedging strategy for a caplet and compare it with the optimal stategy according to the local risk minimizing approach.

Thermodynamics and process analysis for future economic scenarios

Economists are increasingly interested in forecasting future costs and benefits of policies for dealing with materials/energy fluxes, polluting emissions and environmental impacts on various scales, from sectoral to global. Computable general equilibrium (CGE) models are currently popular because they project demand and industrial structure into the future, along an equilibrium path. But they are applicable only to the extent that structural changes occur in or near equilibrium, independent of radical technological (or social) change. The alternative tool for analyzing economic implications of scenario assumptions is to use Leontief-type Input-Output (I-O) models. I-O models are unable to endogenize structural shifts (changing I-O coefficients). However, this can be a virtue when considering radical rather than incremental shifts. Postulated I-O tables can be used independently to check the internal consistency of scenarios. Or I-O models can be used to generate scenarios by linking them to econometric macro-drivers (which can, in principle, be CGE models). Explicit process analysis can be integrated, in principle, with I-O models. This hybrid scheme provides a natural means of satisfying physical constraints, especially the first and second laws of thermodynamics. This is important, to avoid constructing scenarios based on physically impossible processes. Process analysis is really the only available tool for constructing physically plausible alternative future I-O tables, and generating materials/energy and waste emissions coefficients. Explicit process analysis also helps avoid several problems characteristic of pure CGE or I-O models, viz. (1) aggregation errors (2) inability to handle arbitrary combinations of co-product and co-input relationships and (3) inability to reflect certain non-linearities such as internal feedback loops.     

China–US trade: implications on conflicts

ABSTRACT

In this study, we examine various aspects of China’s trade, the U.S.’ trade, and the bilateral trade between the two countries. The analysis of each aspect has direct and indirect implications on trade conflicts between the two countries. We focus on important factors, such as the growth of trade, import penetration, increased competitiveness of Chinese firms, comparative advantages of Chinese goods, China’s WTO entry and its compliance, and bilateral trade imbalance. While each of the factors can lead to trade frictions, individual factors will not have led to a large-scale trade war. These factors converge within a brief period and thus can be considered the China shock, thereby making other countries’ adjustments to their economic structures difficult. Therefore, trade frictions are inevitable.     

财政分权框架下的财政政策和货币政策

本文扩展了Barro( 1 990 )和Gong和Zou( 2 0 0 2 )的模型 ,讨论财政分权框架下的政府财政政策和货币政策 ,通过消费者行为、地方政府行为和中央政府行为之间Nash均衡解 ,得到了经济增长率和各参数的隐式关系 ,并且通过数值模拟得到经济增长率与各种税收以及政府间转移支付的关系。我们发现经济增长率和收入税的关系是Laffer曲线 ,消费税对经济增长的影响是正的 ,财产税对经济增长的影响是负的。至于货币政策的影响 ,我们发现货币不再是超中性的了 ,供应量增加可以促进经济增长 ,而且经济中的货币的流通程度越高 ,经济增长率越高。最后 ,本文还讨论了多级地方政府的情况 ,分析了不同税收制度的地区对整个经济增长的不同影响。
