Adjustment Costs,Inventories and Output

This paper analyzes the optimal adjustment strategy of an inventory‐holding firm facing price‐ and quantity‐adjustment costs in an inflationary environment. The model nests both the original menu‐cost model that allows production to be costlessly adjusted, and the later model that includes price‐ and quantity‐adjustment costs, but rules out inventory holdings. It is shown that the firm's optimal adjustment strategy may involve stockouts. At low inflation rates, output is inversely related to the inflation rate, and the length of time demand is satisfied increases with the demand elasticity but decreases with the storage cost and the real interest rate.     

What do interest rates reveal about the functioning of real business cycle models?

This paper begins by documenting the extent to which the predictions of standard Real Business Cycle (RBC) models are incompatible with observed movements in real interest rates. The main finding of the paper is that extending the baseline model to include habit persistence in consumption and adjustment costs to capital significantly improves the model's empirical performance. In our evaluation of the model's performance, we take special care of estimating and testing predictions of the model using both moments drawn directly from the data and moments calculated after identifying shocks to the stochastic trend.     

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.     

Trade-offs in sulfur emission trading in Europe

How to implement emission trading is one question in the current negotiations on a new sulfur protocol in Europe. Whereas the current protocol stipulates a 30 percent uniform reduction, national emission ceilings included in the proposed new protocol imply differentiated reductions. In addition, emission and fuel standards are proposed. This paper examines the costs and environmental impacts of emission trading. Emission trading combined with regulations is a new element in the paper. Calculations using the RAINS (Regional Acidification INformation and Simulation) model suggest that overlaying emission trading on regulations not only reduces the cost savings but has beneficial impacts as well: ecosystem protection is not changed and significant decreases in environmental benefits for countries are largely avoided. Emission trading can also be used to decrease emissions and increase ecosystem protection. If combined with existing legislation, emission trading minimizes losses in expected environmental benefits for some countries, and most countries gain. However, the initial distribution of emission ceilings has to be used so that some countries are not confronted with higher costs. Trade-offs appear to exist between the use of emission trading to achieve cost savings on the one hand, and ecosystem protection and distributional equity on the other.     

Hybrid governance and governance performance in industrial purchasing relationships

Hybrid governance arrangements (e.g. joint action, long-term contracting and vertical coordination) feature regularly as an effective response to inter-firm dependence in the literature of business-to-business relationships. However, current empirical work has paid little attention to whether such governance arrangements really do improve governance efficacy and reduce transaction costs. The present study focuses on the governance efficacy of vertical coordination in industrial business-to-business relationships. Building on transaction costs arguments, the author examines whether vertical coordination is an effective means for adapting to inter-firm dependence, realized as the substantial employment of specific assets.Empirical findings from a survey of 170 industrial supplier–buyer relationships demonstrate that when asset specificity reaches a certain level, greater vertical coordination reduces ex post transaction costs significantly. On the other hand, this efficacy pattern is modest or non-existent in relationships with low asset specificity.The research findings support the basic TCA assumption that the performance of hybrid governance arrangements is highly dependent on a situation of substantial inter-firm dependence with subsequent small-number conditions.     

基于资产专用性的企业融资决策研究

本文采用Williamson的思路,建立了资产专用性与交易成本、生产成本因素在内的综合交易成本分析模型。分析发现,相对于债务融资而言,股权融资有利于避免按市场规则强行清算带来的专用性资产价值损失,运用包络定理证明专用性程度高的资产具有削减生产成本的作用,专用性程度高的资产以股权融资为佳。     

信息冲击对收益波动的影响--基于交易量的实证研究

文章首先将交易量分解为信息交易量和非信息交易量，然后将信息交易量加入广义自回归条件异方差模型（GARCH模型），来分析信息对收益波动的影响。结果发现，信息冲击对收益波动的影响十分显著，投资者对信息到达的反应存在过度反应、过度矫正、适度反应的过程。     

经济伦理与经济发展

经济发展不仅是一个要素投入与资源配置的过程 ,同时也蕴含着深刻的伦理规定 ,是一个价值选择和道德协调的过程。经济伦理对经济发展起着重要的影响作用 :在微观层面上 ,它是一种人力资本 ;在中观层面上 ,它是一种无形资产 ;在宏观层面上 ,它是一种社会资本。经济伦理通过降低交易成本 ,创造合作效益 ,促进资源的优化配置和社会经济的健康发展。同时 ,经济伦理作为一种特殊的经济资源 ,对经济发展的作用性质和方式具有特殊性 ,需要具体地去认识和把握。
