论两种规模经济：专业规模经济和综合规模经济

当前国际上出现了一种“企业规模无关论”的新观点,与我国目前盛行的“唯规模经济论”截然相反。笔者以为,上述两论都失之片面,正确的理论是在承认的前提下,将规模经济分为两类:专业规模经济和综合规模经济。前者因专业化分工效应而扩大产销规模与市场份额;后者因企业(集团)内部协调成本小于市场交易成本而获得效应。随着市场发育和市场交易成本下降,拥有专业规模经济的企业集团,比之拥有综合规模经济的企业集团更能适应市场的变化与竞争。

Altruistic, egoistic and biospheric values in willingness to pay (WTP) for wildlife

We attempt to measure general attitudes and ethical beliefs towards preservation, as well as the importance of each of the three considered value orientations (biospheric, egoistic and altruistic) in WTP estimates. In the present study, we apply the GAC scale to a contingent valuation exercise for the recovery of the common murre (Uria aalge) in Galicia (Spain). Up to now, only a few studies in the field of environmental and ecological economics have analyzed value orientations under the Environmental Concern (EC) framework, obtaining mixed results. In the present work, we conclude that ethical aspects affect the individuals decision making process, and that value orientations play an important role in the pro-environmental attitude formation. These value orientations affect willingness to pay (WTP) estimates for environmental goods.     

论第三方物流的经济性

第三方物流是一种专业化的物流组织，具有很强的经济性。随着第三方物流的发展，它的经济性会发挥的更加充分。第三方物流的经济性，主要包括规模经济性，价值创新性和外部经济性。规模经济性是它的基本特征，价值创新性是它的功能特性，而外部经济性则是它的社会效益的表现。全面理解第三方物流的经济性，有利于企业进行科学的物流决策，有利于政府制定有效的物流发展战略。     

"建筑节地"理念在城市化进程中的诠释

Incentive Regulation of Prices When Costs are Sunk

We present a model featuring irreversible investment, economies of scale, uncertain future demand and capital prices, and a regulator who sets the firm’s output price according to the cost structure of a hypothetical replacement firm. We show that a replacement firm has a fundamental cost advantage over the regulated firm: it can better exploit the economies of scale because it has not had to confront the historical uncertainties faced by the regulated firm. We show that setting prices so low that a replacement firm is just willing to participate is insufficient to allow the regulated firm to expect to break even whenever it has to invest. Thus, unless the regulator is willing to incur costly monitoring to ensure the firm invests, revenue must be allowed in excess of that required for a replacement firm to participate. This contrasts with much of the existing literature, which argues that the market value of a regulated firm should equal the cost of replacing its existing assets. We also obtain a closed-form solution for the regulated firm’s output price when this price is set at discrete intervals. In contrast to rate of return regulation, we find that resetting the regulated price more frequently can increase the risk faced by the firm’s owners, and that this is reflected in a higher output price and a higher weighted-average cost of capital.
