Political Measures for Strategic Environmental Policy with External Effects

This paper investigates an environmental policy designed to reduce the emission of pollutants under uncertainty, with the agent problem as an optimal stopping problem. We first analyze the two cases in which there are one agent and two competing agents by following Ohyama and Tsujimura (2005). When we consider a model of strategic agents, we need to analyze the external economic effect that is peculiar to an agent’s environmental policy implementation. Then, to improve and resolve these external effects, we examine three alternative political measures, comprising an environmental subsidy, an environmental tax and an emission trading system. The results of the analysis indicate that the environmental subsidy and environmental tax promote environmental policy. However, they do not create an incentive to be the leader. On the other hand, an emissions trading system not only promotes environmental policy but also creates an incentive for leadership.This paper was previously circulated under the title “Political Measures for Strategic Environmental Policy with Induced Effects”.

A model of the origins of basic property rights

This paper studies the origins of one of the most basic of property rights, namely, the right of an individual or an organization to the fruits of its labour. My objective is to address the questions of why, when and how this property right can emerge and be made secure. I develop a model of the strategic interaction between two players in the state-of-nature, which is an environment characterized by the absence of any laws and institutions (including property rights and the state). My analysis explores, in particular, the roles of the players' fighting and productive skills on the emergence and security (or otherwise) of this property right.     

Analysing Materials and Energy Flows in an Industrial District using an Enterprise Input–Output Model

Recent approaches to sustainable development leave much room for policies at a local level. In fact, it is becoming evident that targets such as increasing resource productivity, preserving natural cycles, or extending the present level of welfare, are best pursued within the confines of a local area. In particular, environmental changes are best brought about by considering local systems of firms as cornerstones of cooperative strategies and using data on materials and energy use in physical terms. In this paper, an enterprise input–output model is developed for an industrial district, i.e. a local group of firms specialized in the production of a single final output. The model allows for a detailed quantitative analysis of materials and energy flows and the consequent generation of waste and pollution. As a planning tool, the model may be used to evaluate alternative scenarios, such as the possibility of re- using waste taking account of sustainability requirements. An empirical case study applies the model to an industrial district in Southern Italy producing leather sofas.     

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.     

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.     

中国电信业经济影响的定量研究方法--兼论投入产出表的调整

对电信业的经济影响进行定量化研究过去大多采用计量经济学方法。本文在对这些方法进行总结的基础上，提出了采用投入产出方法的思路，并构建了相应的投入产出模型，同时对投入产出表进行了必要的调整，最后采用投入产出方法对20世纪90年代电信业的经济影响进行了实证研究。     

潜在产出估计的文献综述

通过对国内外有关潜在产出的计算方法进行综述,指出目前国外普遍认同的方法是以经济理论为依据的生产函数法,而我国采用的是统计分解方法。统计分解方法有主观性和偏差性较大的缺点,应加以改进。     

奥肯定律与扩大的奥肯模型估计——关于中国就业与经济增长的数量关系实证(1978-2003)

奥肯定律表明与正常的(或潜在的或趋势的)增长率相比,高产出增长伴随着失业率的降低,低产出增长伴随着失业率的上升.作为一种经验规律,奥肯定律在西方很多国家的实践中得到了良好的验证.本文根据1978年以来中国的宏观经济统计数据进行模型回归检验,结果显示我国城镇登记失业率的变化与实际产出增长率之间不存在典型的奥肯规律.由于我国公开的失业率并不能反映真实的市场失业率,为此用就业量代替失业率,建立扩大的奥肯模型,分别对我国第一、二和三产业的就业增长与经济增长的数量关系进行估计.实证的结果显示我国第二、三产业的就业增长与产出增长和物价上涨均为正相关;而我国农业的就业增长与产出增长存在负相关.     

技术独董、经济政策不确定性与企业创新产出

创新产出是企业创新能力的直观体现,也是企业价值创造的源泉。以2008—2017年披露了专利授权信息的中国A股上市公司为样本,研究了独立董事技术专长对企业创新产出的影响。结果显示：（1）技术独立董事显著地促进了企业创新产出,且这种促进作用受到经济政策不确定性的负向调节;（2）技术独立董事是通过提高企业的创新投入来促进企业的创新产出的;（3）技术独立董事兼职席位与企业创新产出呈倒U型关系。根据上述研究结论,企业应当增加技术独立董事的引入并适当限制技术独立董事在其他企业兼职的行为,以充分发挥技术独立董事的创新驱动效应,提高企业创新产出。
