Economic analysis of the production of ready-to-eat ‘Gbegiri'' bean mix powder

Economic evaluation of the industrial production of Gbegiri bean soup mix was conducted using the NPV (net present value) and IRR (internal rate of return) methods. A uniform cash flow over a 10-year plant life with zero salvage value was assumed. Sensitivity analysis was conducted by varying the number of production days (330, 250 and 150 days) at 100% plant capacity and varying the plant capacity (100, 85 and 70%) for a 330-day production schedule. Some components of the operating cost reduced as the number of production days or the plant capacity were reduced. The production cost and product cost per unit increased with reduction in either the plant capacity utilisation or the number of days. The economic performance of the plant when operated for 150 days was not attractive. The results indicated that the plant should not be operated for less than 250 days in the year. Flexibility in the plant capacity utilisation in the range 70–100% yields a good economic performance.     

国有资产管理体制改革的简析

国有资产管理体制改革必须面对资产安全与经济效率的现实矛盾。市场经济的实质是资本经济，效率是市场经济的最高价值追求。国有资产管理体制改革应该体现效率优先的价值取向。落实自然人所有权、构建董事责任保险制度、树立法治在建构国有资产管理体制中的权威地位，是实现效率目标的重要战略措施。     

Leontief's Great Leap Forward: Beyond Quesnay,Marx and von Bortkiewicz

Wassily Leontief's input-output analysis is often interpreted simply as a logical next step in the chain of ideas from Quesnay to Marx to von Bortkiewicz, the last of these having been Leontief's thesis adviser in Berlin. Here, it is shown that input-output is far more than that. Unlike any predecessor, it is a flexible model with widely varied applications that permits direct empirical evaluation. This is illustrated by application to net energy calculations, showing that the normal evaluation methods that ignore input-output considerations probably overestimate by 20 to 60% the net energy yield of projects designed to save energy.

Strategic investment analysis for migration beyond 3G wireless networks

This paper analyzes investment alternatives for cellular operators who deploy either universal mobile telecommunications systems (UMTS) with high speed data packet access (HSDPA) networks or UMTS with Wi-Fi networks, for moving beyond 3G-networks. The evaluated business scenarios focus on two different deployment alternatives: UMTS with HSDPA and UMTS integrated with Wi-Fi. HSDPA deployment targets the overlay on the existing UMTS cells, whereas Wi-Fi covers only indoor hot spot areas where data demand is high. Capital investments and operational costs as well as revenue streams have been analyzed for the two types of network architectures. Techno-economic methodologies have been applied for this study and results are derived that are presented and discussed for two types of wireless networks.     

Friend or Foe? On the role of institutional reforms in the investment development path of Central and East European economies

Many existing studies on emerging markets and firms have concentrated on the separate effects of institutional reforms and quality of the institutional infrastructure for attracting inward foreign direct investment (FDI) and fostering outward FDI. We argue that both these perspectives should be considered in an interplay, as there are links between inward and outward FDI in a country's economic development, which is captured by the investment development path (IDP) concept. Moreover, while predominant attention has been paid to emerging markets, little has so far been done to evaluate the sustainability of the institutional development, including later post-transition stages. We extend the IDP with insights from the institutional theory and conduct a comparative analysis of the effects of institutional reforms on IDP paths of ten Central and Eastern European (CEE) post-communist European Union (EU)-members. We find that while most of the studied post-transition economies follow a quadratic relationship between the net outward investment (NOI) position and each country's economic development, the role of institutional reforms is not in all cases accelerating the movement through the stages of the IDP. We attempt to explain the ambiguous role of institutions in an ensuing detailed discussion of the investigated countries.

The Welfare Economic Theory of Green National Accounts

This paper takes a critical look at the literature on green national accounts. The problem studied is to find a linear index of economic variables that responds to perturbations in the same direction as social well-being. The thesis of a large literature, that net national product (which is a flow) is that index in closed economies, is shown in some interpretations to be simply false and in others to suffer from deep estimation problems. It is argued that capital depreciation using shadow prices should certainly be included in national accounts, but that the right welfare index is a comprehensive measure of wealth, defined as the shadow value of an economy’s stock of all capital assets. It is shown that comprehensive wealth is usable as a criterion for policy evaluation as well as for determining sustainable economic development.
