Behavioral Objectives and Student Learning Contracts in the Teaching of Economics

The authors present a series of writing assignments that teaches students how to evaluate and critique the written economic work of others. The foundation text is McCloskey's (2000) Economical Writing. The students' dialogues with McCloskey, with each other, and with the authors of the pieces they evaluate sharpen their understanding of, and ability to use, language as an instrument of economic thought. Interviews with former students identify specific benefits from the student perspective of this approach. The authors show how the assignment series can be modified in several ways and how the general approach, as well as the foundation text, can be used in different economics courses.     

Student Evaluations of Teaching and the Cognitive Level of Economics Courses

The Journal of Economic Education of Fall 1973 was devoted to the subject of student evaluations of teachers. That issue has engendered a great many papers, only a few of which can be published in the JEE because of space limitations. Michael Everett's report is not a mere replication of previous research on the subject, but adds a new dimension—the possible effect of student evaluations on the cognitive level of college economics courses. His finding that students may favor professors who emphasize lower level cognitive material will surely be distressing to many teachers, and should cause sober reflection on the part of administrators and others involved in establishing faculty evaluation procedures and policies.     

Transaction Costs, Suboptimal Termination and Default Probabilities

The same option-based methodology now commonly used to value mortgages and their termination features also can be applied to calculate the probabilities that mortgage default will occur. This paper pursues that idea, and furthermore, enriches the idealized option-based approach by introducing both transaction costs and "suboptimal" termination. These latter features capture the individual considerations that cause a mortgage holder's actions to differ from what rationality would indicate based solely on the market value of the mortgage. These features are of considerable importance if the results of options-based models are to be made comparable to those calculations of default probabilities occurring in the empirical literature.     

Determination of Long‐run and Short‐run Dynamics in EC‐VARMA Models via Canonical Correlations

This article studies a simple, coherent approach for identifying and estimating error‐correcting vector autoregressive moving average (EC‐VARMA) models. Canonical correlation analysis is implemented for both determining the cointegrating rank, using a strongly consistent method, and identifying the short‐run VARMA dynamics, using the scalar component methodology. Finite‐sample performance is evaluated via Monte Carlo simulations and the approach is applied to modelling and forecasting US interest rates. The results reveal that EC‐VARMA models generate significantly more accurate out‐of‐sample forecasts than vector error correction models (VECMs), especially for short horizons.

Modern Likelihood‐Frequentist Inference

We offer an exposition of modern higher order likelihood inference and introduce software to implement this in a quite general setting. The aim is to make more accessible an important development in statistical theory and practice. The software, implemented in an R package, requires only that the user provide code to compute the likelihood function and to specify extra‐likelihood aspects of the model, such as stopping rule or censoring model, through a function generating a dataset under the model. The exposition charts a narrow course through the developments, intending thereby to make these more widely accessible. It includes the likelihood ratio approximation to the distribution of the maximum likelihood estimator, that is the p^? formula, and the transformation of this yielding a second‐order approximation to the distribution of the signed likelihood ratio test statistic, based on a modified signed likelihood ratio statistic r^?. This follows developments of Barndorff‐Nielsen and others. The software utilises the approximation to required Jacobians as developed by Skovgaard, which is included in the exposition. Several examples of using the software are provided.     

The political economy of wage-earner funds: policy debate and Swedish experience

Various European proposals for wage-earner funds are briefly surveyed. The central issues of the policy debate surrounding these funds are then discussed. It is argued that the outcome of this debate was not determined solely by a rational appraisal of the economic costs and benefits of the various policy options. Wage-earner funds raise questions concerning the ownership and control of capital and have therefore been the focus of political conflict between powerful interest groups. The paper then analyses the experience of wage-earner funds in Sweden, dealing with their objectives, behaviour and economic performance.     

The structure of Walras's mature model of capital goods markets

This essay examines the capital goods markets in the comprehensive model that Léon Walras constructed during the mature period of his theoretical work. the essay answers fundamental questions about the participants and market institutions in his model; the monetary or nonmonetary nature of the model; his assumptions about the nature of capital goods; his definitions of the rate of interest and the rate of net income and their functions in his model; and the roles in his model of the Bourse, the loan market and the rental market for capital goods.     

Marriage,Divorce and Prostitution: Economicc Sociology in Medieval England and Enlightenment Spain

“Marriage, Divorce and Prostitution: Economicc Sociology in Medieval England and Enlightenment Spain” by Robert B. Ekelund,Jr., Donald R. Street and Audrey B. Davidson.

This paper studies the medieval insititutions of marriage, divorce and prostitution through the prism of the economic sociology and rent-seeking behaviour on the part of the medieval Roman Catholic Church. Regulation by Church or state-Particular prohibitions and regulation of recontracting – created costly alternatives and substitutes for low-cost recontracting of marriage vows. In addition to a brief survey of the instititional situation in medieval England, we bring to light the economic sociology of the Spaniard Francisco de Cabarrùs relating to the marriage market and marital utitlity. Indirectly we suggest that exogenous restrictions in marriage markeers create unappropriated costs and the impetus for change in social institutions over time over time.     

Measuring the efficiency of search engines: an application of data envelopment analysis

This paper adopted the data envelopment analysis (DEA) method to investigate the efficiency of several search engines. A query search on a search engine is modelled as a production process. The input and output vectors are defined and measured accordingly. We studied seven engines, Alta Vista, Excite, Hotbot, Lycos, Infoseek, Open Text, and WebCrawler and found that Alta Vista, Excite, Infoseek, and WebCrawler are efficient but the other three are not. Possible efficiency improvements are calculated.     

Ocupational segregation,labour force participation and the relative earnings of men and women

A model of the labour market is developed in which particiaption rates of men and women,wages rates of men and women and occupational segregation are determined simultaneously. The model is estimated using cross-sectional data from Australia. The most important empirical results are that (a) particiaption rates,wage rates and occupational segregation should be viewed as being simultaneously determined,(b) differences in male and female labour-force attactment and human capital attainment are important determinants of the gender composition of occupations and (c)there is little direct evidence in this study to support discrimination-based theories of occupational segregation.
