The automobile industry and new trade theory: A classroom experiment

In this study, the author describes a classroom experiment on new trade theory appropriate for undergraduate international economics and trade courses. Students portray U.S. and Japanese automobile manufacturers with different average cost schedules. There are five rounds in the experiment, starting with autarky in the 1960s and ending with the Great Recession of 2008–9. In each round, the instructor announces a market price and quantity and then each producer calculates its market share, average cost and profit; and makes its shutdown decision. By varying the market price and size, the experiment illustrates the gains from intra-industry trade and also how efficiency gains and economic recession impact individual firm performance.     

Teaching Nash Equilibrium and Dominance: A Classroom Experiment on the Beauty Contest

Abstract: The authors' aim in this article was to show how the use of classroom experiments may be a good pedagogical tool to teach the Nash equilibrium (NE) concept. The basic game is a version of the beauty contest game (BCG), a simple guessing game in which repetition lets students react to other players' choices and converge iteratively to the equilibrium solution. The authors perform this experiment with undergraduate students with no previous training in game theory. After four rounds, they observe a clear decreasing tendency in the average submitted number in all groups. Thus, the findings show that by playing a repeated BCG, students quickly learn how to reach the NE solution.     

Price discrimination: A classroom experiment

In this article, the authors describe a classroom experiment aimed at familiarizing students with different types of price discrimination (first-, second-, and third-degree price discrimination). During the experiment, the students were asked to decide what tariffs to set as monopolists for each of the price discrimination scenarios under consideration. The objective was to allow the students to work empirically, through trial and error, selecting tariffs for each type of discrimination that would maximize a monopolistic entrepreneur's profits. The purpose of the exercise also was to enable the students to differentiate each type of price discrimination and to set tariffs in each case, as well to help them understand the repercussions in terms of welfare for each type of price discrimination.     

统一利润率与差别利润率——兼论两种均衡体系的比较

瓦尔拉斯把资本形成方程引入一般均衡体系后出现了内在的不一致性,从而在异质资本品的假设下,一般均衡体系只存在“差别利润率”。在斯拉法体系中,不同的资本品部门却拥有“统一利润率”。两种类型的利润率体现了两种均衡体系的对立。与“差别利润率”相联系的一般均衡体系只研究一般生产过程中的资源配置,体现技术关系;而与“统一利润率”相对应的斯拉法体系则涉及特定市场经济关系下的总量分配,体现社会关系。而后者才可以更好地解释市场经济中的现实问题。     

Investment and Finance in de novo private firms: Empirical Results from the Czech Republic, Hungary and Poland

In this paper we use a survey of 281 Czech, Hungarian and Polish newly-established small private firms in order to shed some light on the constraints these firms face in the credit market. The results of our survey show that imperfections in capital markets in Central European economies do not seem to actually inhibit the growth of new private firms. Credit markets do exist for de novo private firms in the three Central European transition economies studied, and they provide quite a large amount of financing from an early stage of the existence of firms. Financial intermediation works reasonably well as far as de novo private firms are concerned: loss-making de novo firms have a lower probability of getting credit than profitable ones. Banks protect themselves against the risk of a deteriorating pool of borrowers by requiring collateral for their loans. We do not find convincing evidence concerning the existence of adverse selection. Loss-making firms are not ready to pay higher interest rates than profitable firms and are not more likely to ask for credit than profitable firms.     

我国上市公司的投资行为研究:基于新古典理论的检验

从新古典投资理论出发,通过研究我国上市公司投资行为对资本成本的响应程度以及企业投资规模与利润水平的关联程度,笔者发现:(1)我国上市公司的投资行为总体上符合新古典经济理论所期望的利润最大化目标下的企业投资行为范式;(2)由于存在较大的资本存量调整成本,新古典经济理论倡导的干预投资的经济政策对我国企业的投资行为在长期内会发生调节作用,但短期内的作用非常有限。     

Evaluating the flipped classroom: A randomized controlled trial

Despite recent interest in flipped classrooms, rigorous research evaluating their effectiveness is sparse. In this study, the authors implement a randomized controlled trial to evaluate the effect of a flipped classroom technique relative to a traditional lecture in an introductory undergraduate econometrics course. Random assignment enables the analysis to eliminate other potential explanations of performance differences between the flipped and traditional classrooms, while assignment of experimental condition by section and lesson enables improved statistical precision. The authors find that the flipped classroom increases scores on medium-term, high-stakes assessments by 0.16 standard deviation, with similar long-term effects for high-performing students. Estimated impacts are robust to alternative specifications accounting for possible spillover effects arising from the experimental design.     

The psychology of sunk cost: A classroom experiment

Abstract

Economics and business students are taught that sunk costs are irrelevant to their decisions. Yet, there is ample evidence that managers fail to integrate this simple rule and fall prey to what is known as the sunk-costs bias. To mitigate cognitive biases, such as the sunk-cost bias, educators must raise students’ awareness of these common judgment errors. In this article, the author proposes a classroom activity that actively engages students and allows them to identify this bias in their own judgments. The activity builds on a series of experiments from the psychology literature. The author discusses how these experiments have been adapted for classroom use and presents evidence suggesting that the activity increased students’ awareness of the sunk-cost bias and improved their decision-making skills.     

Flexible and Committed Profit Sharing with Wage Bargaining: Implications for Equilibrium Unemployment

We analyze the relationship between profit sharing, employee effort, wage formation and unemployment under different relative timings of the wage and profit sharing decisions. The optimal profit share under commitment exceeds that under flexibility, because through a profit share commitment the firm can induce wage moderation. The negotiated profit sharing depends positively on the bargaining power of trade union and it has both effort-enhancing and wage-moderating effects. Higher profit sharing is shown to reduce equilibrium unemployment under ``sufficiently rigid' labor market institutions, but it can harm employment when labor market ``rigidities' are ``small enough'.

A study on Spanish female labour supply with job offer restrictions

This paper analyses female working time taking into account restrictions on hours. Moreover, we compare two different specifications of employment opportunities. The first one assumes that the probabilities of receiving different job offers are constant whereas in the second one we incorporate the hypothesis that these probabilities depend on individual characteristics. The model is estimated using a sample of Spanish women from the Encuesta Piloto sobre Ganancias y Subempleo (1990). The results suggest that incorporating job restrictions is a valuable extension and that individual variables affect the availability of job offers.JEL Classification: J22This paper is based on the second chapter of my Ph. D. thesis defended at the University of Oviedo in December 2000. I am very grateful to Víctor M. Fernández and Jaume García for their valuable help and to Emla Fitzsimons for her linguistic revision of the text. I am also grateful to two anonymous referees for their suggestions that have significantly improved this paper. Any remaining errors are my responsibility.

Inter-ethnic trust and reciprocity: results of an experiment with small businessmen

We investigate inter-ethnic trust and reciprocity by having subjects from distinct ethnic origins play the trust game [Games Econom. Behav. 10 (1995) 122]. The participants in the experiment are male small businessmen of Turkish or Belgian ethnic origin, all of whom have a business in the same city (Ghent, Belgium). Our main finding is that the average levels of trust and reciprocity are independent of ethnic origin and, moreover, independent of the ethnic origin of the opposite party.     

Estimation of the public benefits of urban water supply improvements in Ethiopia: a choice experiment

Improving existing drinking water supply services in developing countries depends crucially on available financial resources. Cost recovery rates of these services are typically low, while demand for more reliable services is high and rapidly growing. Most stated preference-based demand studies in the developing world apply the contingent valuation method and focus on rural areas. This study examines household Willingness to Pay (WTP) for improved water supply services in a choice experiment in an urban area in Ethiopia, a country with the lowest water supply coverage in Sub-Saharan Africa. The design of the choice experiment allows estimation of the value of both drinking water supply reliability and safety. The estimated economic values can be used in policy appraisals of improved supply investment decisions. Despite significant income constraints, households are willing to pay up to 80% extra for improved levels of water supply over and above their current water bill. Women and households living in the poorest part of the city with the lowest service levels value the improvement of water quality most. As expected, also averting behaviour and expenditures play an important role.     

横向兼并的均衡影响分析——基于供给函数竞争的兼并模型

对于横向兼并所产生的影响,现有研究成果多是在产量竞争的古诺模型或基于价格竞争的伯川德模型基础上进行的.本文以Ugue(2004)提出的供给函数竞争概念为基础,考察了横向兼并、产业集中与福利权衡的关系,分析在同质产品市场上,供给函数竞争对企业横向兼并产生的均衡影响,并与古诺模型做了对比分析.基本结论为:供给函数竞争下,任何兼并都会使产业的总产出下降,价格升高.供给函数竞争导致产量的下降,不仅仅由于兼并企业减少产量,而且非兼并企业也会减少供给,结果导致兼并总是有利可图.     

Multinational experience and the creation of linkages with local firms: evidence from the electronics industry

This paper focuses on multinational companies' creation of linkageswith local firms in the electronics industry. Evidence is drawnfrom a novel data-set, covering international operations ofthe top European and US electronics companies, over the period1984–95. Econometric tests are provided to highlight howfirms' multinational experience, measured by the extent of theirpresence in foreign countries, affects cooperative agreements,as opposed to licensing and foreign direct investments. It ishighlighted that multinationals' subsidiary accumulation hasa positive and significant impact on collaborative linkageswith local firms. This contrasts with the transaction cost viewunderlying most market-entry literature, but is consistent witha dynamic efficiency perspective which emphasises the role oflinkages in learning and knowledge accumulation and exploitation.     

Aging, Asset Markets, and Asset Returns: A View From Europe to Asia

The extent of the demographic changes is dramatic especially in some Asian and European countries. This paper investigates the effect of aging on global asset markets and asset returns, focusing on markets for productive capital, and especially on interactions between European and Asian economic development. Aging has complex effects on the markets for real capital. If elderly people save less than younger people, interest rates will increase. At the same time, however, the younger generation becomes smaller, which reduces the demand for new investment. The equilibrium effect is thus uncertain. Our multicountry computational equilibrium model delivers a subtle picture: there will be some decline in the return from productive capital, but it is relatively small. We find noticeable interaction effects between labor market and pension reforms in Europe on the one hand, and the demographic and economic developments in Asia, especially India and China, on the other hand.     

Revisiting the impact of impure public goods on consumers’ prosocial behavior: A lab experiment in Shanghai

In this study, we implemented a dictator game experiment to examine how the increase of the public characteristic in an impure public good affects individuals’ prosocial behaviour. A within‐subject design was used in the experiment. The dictator game was repeated six times with an impure public good introduced in four of them. We observe that the increase of the public characteristic in an impure public good partly crowds out individuals’ subsequent donations, which could be explained by a seemingly ‘mental accounting’ mental process. In addition, we also find that the selfish behaviour of individuals in dictator games with impure public goods, to some extent, has an inertia influence on their subsequent donations when the impure public good is removed.     

Portfolio choice with internal habit formation: a life-cycle model with uninsurable labor income risk

Motivated by the success of internal habit formation preferences in explaining asset pricing puzzles, we introduce these preferences in a life-cycle model of consumption and portfolio choice with liquidity constraints, undiversifiable labor income risk and stock-market participation costs. In contrast to the initial motivation, we find that the model is not able to simultaneously match two very important stylized facts: a low stock market participation rate, and moderate equity holdings for those households that do invest in stocks. Habit formation increases wealth accumulation because the intertemporal consumption smoothing motive is stronger. As a result, households start participating in the stock market very early in life, and invest their portfolios almost fully in stocks. Therefore, we conclude that, with respect to its ability to match the empirical evidence on asset allocation behavior, the internal habit formation model is dominated by its time-separable utility counterpart.     

Parental involvement and Children's human capital: A tax-subsidy experiment

Parental time with children has a significant influence on early childhood development, future accumulation of a wide array of cognitive and non-cognitive skills and the ultimate success of the child. The model presented in this article features endogenous fertility and labour supply while distinguishing between various types of parental time spent with children. We conduct a quantitative analysis to investigate the importance of the role of family for children's skill formation. In the model, parents are subsidized for spending publicly verifiable productive time with their children. Such intervention can significantly enhance the human capital of children, yet it affects the overall labour supply of the primary caretaker in an ambiguous way.
