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. 相似文献

The vast majority of studies in college economics have dealt with the introductory principles course. In one of the rare research projects dealing with other courses, Professor Cohn attempts to identify factors affecting student performance in economic statistics. He considers such variables as grade point average, graduate vs. undergraduate status, major field, sex and credits in economics, mathematics and statistics. There are a few recognized limitations to his model, but the reader will find some of his results to be surprising indeed. 相似文献

Using local variation between municipalities, I analyze the degree to which the price of high‐quality publicly subsidized childcare affects female employment following maternity leave. Importantly, prices are income dependent and thus likely endogenous, yet by exploiting information on minimum income compensation during non‐employment, I bypass this problem. The results show that the price negatively affects employment. A price increase of €1 per month decreases employment by 0.08%, which corresponds to a price elasticity of −0.17. These effects prevail during the first 12 months after childbirth. I also find that availability of childcare increases employment. 相似文献

Abstract A laboratory‐type experiment was conducted to examine potential information overload causes and solutions. It was found that both information quantity and information complexity are potential causes of information overload. The experiment results also suggested that information overload problems may be reduced through carefully designed information display patterns. When designing survey questionnaires, attention must be given to potential causes of information overload. Methods of presenting information that ameliorate information overload must also be considered. As demonstrated in this study, survey designs can be tested in controlled, laboratory‐type experiments. The results of these experiments can then be used to improve the design of field survey questionnaires. 相似文献

The author uses a simple classroom experiment to develop the economic model of monopoly. As a pedagogical tool, the experiment introduces students to the nature of the monopoly problem and motivates them to think of the associated efficiency issues as a divergence between private benefits and social contributions. As a test of economic principles, the experiment highlights the role of information and fairness ideals in determining economic outcomes. 相似文献

Disaster‐relief logistics consists of providing adequate emergency supplies rapidly to the affected people so as to minimize human suffering and death. This study empirically examines the impact that the shortage of fuel, a commonly encountered problem in many disaster situations, can have on the effectiveness of disaster‐relief logistics operations. We focus on investigating the following two issues: (1) whether the shortage of fuel is more damaging in attaining logistical goals than the equivalent‐sized shortage in emergency supplies themselves, and (2) what types of vehicles should be used when the fuel supply is limited. Results suggest that the shortage of fuel may be more damaging than the shortage of emergency supplies, and that smaller trucks may be preferred to larger trucks when the shortage of fuel becomes severe. 相似文献
