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.     

A Classroom Tariff-Setting Game

The author outlines a classroom tariff-setting game that allows students to explore the consequences of import tariffs imposed by large countries (countries able to influence world prices). Groups of students represent countries, which are organized into trading pairs. Each group's objective is to maximize welfare by choosing an appropriate ad valorem tariff that may be changed intermittently throughout the game. The game is built on a computable general-equilibrium model, which allows each nation's utility and terms of trade under alternative tariff regimes to be expressed quantitatively. The exercise encourages students to consider terms-of-trade improvements and efficiency losses resulting from large-country tariffs and provides a framework to discuss the Nash equilibrium of a tariff war. The game is a useful supplement to traditional teaching methods.

Your Place in Space: Classroom Experiment on Spatial Location Theory

The authors detail an urban economics experiment that is easily run in the classroom. The experiment has a flexible design that allows the instructor to explore how congestion, zoning, public transportation, and taxation levels determine the bid–rent function. Heterogeneous agents in the experiment compete for land use using a simple auction mechanism. Using the data that is collected, a bid–rent function is derived, and the experimental treatment is altered over the course of three sessions to uncover core concepts in urban economics. Moreover, this provides a tangible experience that can be used to help undergraduates relate to urban issues such as the steep rent gradient found around many larger colleges and universities.     

Textbook Treatments of the Financial Market in the IS-LM Model

Intermediate macroeconomics textbooks introduce financial markets into the IS-LM analysis but typically as a beginning-of-period consideration. Here the financial market is introduced in an end-of-period model.     

Using a Simple Contest to Illustrate Mechanism Design

This article describes a simple classroom activity that illustrates how economic theory can be used for mechanism design. The rules for a set of contests are presented; the results typically obtained from these contests illustrate how the prize structure can be manipulated in order to produce a particular outcome. Specifically, this activity is designed to show how changing the prize structure can impact both the contestants’ average efforts and the effort level of the hardest-working contestant. The activity can be run in a 50-minute class, has instructions that fit on a single piece of paper, and, although it can be run in large classes, requires only six students.     

Price of High‐quality Daycare and Female Employment

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.

政府补贴是我国发展农业保险的重要保障——来自我国农业保险试点模式的调研报告

新一轮农业保险试点形成了“安信模式”、“安华模式”、“互助制模式”、“共保体”模式和“安盟模式”等5种模式。从这5种模式运行看,政府补贴是发展农业保险的重要保障,经济发达地区政府补贴多,运行就比较好;经济欠发达地区,政府补贴少,运行就比较困难。建议政府明确采取补贴促进农业保险发展的态度,并加大政府补贴的力度。
