Cournot Competition and Hit-and-Run Entry and Exit in a Teaching Experiment

Instructors can use a computerized experiment to introduce students to imperfect competition in courses on introductory economics, industrial organization, game theory, and strategy and management. In addition to introducing students to strategic thinking in general, the experiment serves to demonstrate that profits of a firm fall as the number of competitors is increased in a market and that firms enter profitable markets. The authors have used the experiment in undergraduate classes on strategy and management as well as in master of business administration courses with great success.

浅谈贯通培养项目基础教育阶段和谐师生关系的构建

和谐师生关系是一种较为民主的师生关系,通过班主任和学生之间的心灵沟通和思想交流,实现师生之间人格魅力的互相影响,实现师生双方的和谐发展,以取得较好的教育效果。在贯通培养项目基础教育阶段,能否成功地开展教育,师生关系是一个十分重要的影响因素。哈贝马斯的交往行为理论对和谐师生关系的建立具有一定的启示意义。本文分析了贯通培养项目基础教育阶段和谐师生关系构建的重要性,和谐师生关系的实现需要班主任和学生形成精神交往,通过交流进行互动,实现互相理解。具体交往方式有三种,即分享、对话和理解。在此基础上,提出构建\"亦师亦友型师生关系模式\"的基本要点。     

溶胶-凝胶法制备SiO2/TiO2多层膜的研究

通过对溶胶、热处理温度以及溶胶-凝胶过程中反应和存放的环境温度及湿度等参数的调整,研究了在实验室条件下制备SiO2/TiO2多层膜的方法.已制备出折射率可调的溶胶,所镀制的SiO2薄膜折射率在1.18～1.41之间可调,TiO2薄膜折射率在1.80～2.20之间可调.采用椭偏仪、红外分光光度计、紫外-可见分光光度计等对所制得的多层膜的性能进行了研究,结果表明,实验条件对SiO2/TiO2多层膜的制备非常重要.     

Drivers and barriers of peer-to-peer accommodation stay – an exploratory study with American and Finnish travellers

The explosive growth of peer-to-peer (P2P) accommodation service presents a potential transformation in the competitive landscape of accommodation sector. This research explores the market characteristics and the factors that drive and hinder the use of P2P accommodation to better explain the phenomenon of collaborative consumption in the tourism and hospitality marketplace. Using responses from travellers residing in the United States and Finland, exploratory factor analyses revealed two factors that drive the use of P2P accommodation: social appeal (desire for community and sustainability) and economic appeal (cost savings). The barriers include issues of trust, efficacy and familiarity with the system, and cost. The empirical evidence from this study suggests several managerial implications for tourism and hospitality businesses and directions for future research.     

Determinants of the global and regional CO2 emissions: What causes what and where?

Using the Stochastic Impacts by Regression on Population, Affluence, and Technology (STIRPAT) model and an unbalanced panel dataset of 128 countries covering 1990–2014, this study aims to examine the key impact factors (KIFs) of the global and regional carbon dioxide (CO₂) emissions and analyse the effectiveness of non-renewable and renewable energies. Given the potential cross-sectional dependence and slope heterogeneity, a series of econometric techniques allowing for cross-sectional dependence and slope heterogeneity is applied. The overall estimations imply that the KIFs at the global level are economic growth, followed by population size, non-renewable energy, and energy intensity in order of their impacts on CO₂ emissions; conversely, the KIFs at the regional level vary across different regions and estimators. The results also suggest that renewable energy can lead to a decline in CO₂ emissions at the global level. At the regional level, only for two regions (i.e., S. & Cent. America and Europe & Eurasia) renewable energy has a significant and negative effect on CO₂ emissions, which may be affected by the share of renewable energy consumption in the primary energy mix. Finally, the results indicate varied causality relationships among the variables across regions.

The Global Financial Crises of 2007–2010 and the future of capitalism

This paper presents an analysis of the 2007-2010 Global Financial Crisis which started with the sub-prime crisis in the U.S. and became global very fast. It argues that the financial system in the United States is a complex interlocking structure of markets, institutions and regulators. The causes and culprits of the crisis, the misaligned incentives of participants and exogenous events such as the wars in Afghanistan and Iraq, precipitated failure in key markets: commodities, sub-prime housing, equities, and credit. One of the strategic consequences of this crisis is that the US will lose its dominance in world power, the frequent crises and vulnerabilities of the Neoliberalism and examines the future of capitalism. Of the alternatives to economic system, the capitalism is the most viable economic system. However, it must adopt real and efficient allocation of resources to maximize welfare of all parties and seriously address the income inequality. It must reject crony capitalism, enact true financial regulation of institutions and markets, end corporate socialism and address the system’s structural deficiencies.
