Comments on John Roemer’s first welfare theorem of market socialism*

Abstract

In this comment on John Roemer’s “theory of cooperation with an application to market socialism”, I extend Roemer’s first welfare theorem of market socialism in two directions. First, I prove a version of the theorem that deals with non-linear taxation. Second, I offer a connection between the theorem and welfare equality. I then argue that the models and questions that Roemer contribute to bring to welfare economics raise questions that go much beyond the research on socialist ethics. In particular, I introduce a positive model of moral behavior that yields different predictions from Roemer’s Kantian model. I conclude that individual morality should become a central concern of welfare economists.     

Estimating the revenue losses of international corporate tax avoidance: the case of the Czech Republic

International corporate tax avoidance by multinational enterprises likely lowers the Czech Republic’s corporate income tax revenue, but it is not clear by how much. To clarify this I first review existing estimates of the revenue losses of international corporate tax avoidance to government revenue worldwide. I then discuss revenue estimates relevant for the Czech Republic and develop a few new, albeit only illustrative, ones. None of the existing research focused on the Czech Republic nor did the six recent international studies I examine provide reliable estimates for the Czech Republic. The extrapolations from these studies result in a revenue loss of a quite wide range with a median of 10% of current corporate income tax revenues. The other newly prepared estimates, based on firm-level and aggregate data, are of similar magnitude. I conclude with a discussion of these rough estimates as well as questions for further research and policy recommendations.     

二战期间苏联核战略启动决策述论——基于苏联解密档案的研究

第二次世界大战期间,苏联就是否启动核战略工程进行研究和决策。二战初期,苏联领导人并不重视核武器的研究,而在1941年6月22日遭到德国法西斯入侵后更是集中全力进行卫国战争。一部分具有远见的苏联科学家不断呼吁苏联领导层重视核武器研制,苏联间谍机构也提供了大量关于英美等国核研究的重要情报,这些因素促使苏联领导层逐渐重视核武器的研制。而在美国核垄断的威胁下,苏联领导人最终作出决策,启动了苏联的核战略工程。     

Financial Outcomes in Adolescence and Early Adulthood in Australian Longitudinal Data

This article describes and catalogues person-specific measures of financial outcomes that are available for adolescents and young adults in three large longitudinal Australian surveys: the Longitudinal Surveys of Australian Youth, the Longitudinal Study of Australian Children, and the Household, Income and Labour Dynamics in Australia Survey. It summarises international research that has been conducted on young people's financial outcomes, illustrating outcomes that have been investigated, research questions that have been asked, and distinctions that have been drawn between adolescents and young adults. It considers the strengths and weaknesses of the three surveys for extending this research into the Australian context.     

An introduction to the Millennium Project

The pace, complexity, and globalization of change requires attention to the future. The change of millennia — the coming of the year 2001 — provides an opportunity, a psychological focus, for a global review of past achievements and problems and a unique chance to assess and reflect on future issues and opportunities.Unfortunately, there is as yet no mechanism or information utility to support a worldwide effort to study past achievements and problems or future issues and opportunities. Although there are many individual, isolated, special purpose, and one-time study efforts underway, there is no international system that can provide coherence or continuity to these studies, including feedback and sharing of information, and, in particular, the systematic exploration of future possibilities and policy alternatives. With growing interest in the future, the spread of instantaneous and global communications, the advent of powerful new nondeterministic modeling techniques, the ability to evoke, capture, and share information and perceptions with systematic questioning techniques and software, the proliferation of data bases, and knowledge visualization, it is now possible for futurists, scholars and others around the world to interact globally and take a fresh look at the future possibilities and policies in ways not previously possible.As the World Bank provides an ongoing system for research and feedback to improve economic policy, so too the United Nations University could provide an ongoing system for the improvement of futures research and its application to the policy process. According to a series of interviews, questionnaires, and meetings with leading futurists and scholars around the world, the proposed “Millenium Project” has the potential to become such a system.This study had as its principal objective determining the design of an information system that could effectively tap contributors, worldwide, to focus on lessons of the past that bear on world issues and the potential of future developments for intensifying or mitigating these and future issues. The first phase of the feasibility study was both methodological and substantive. Worldwide panels of experts contributed their judgments about the method or process of organizing the project; and the system that emerged from this interaction was applied in a prototype study to the issues of growing world population and the environment.During the first phase of the feasibility study, we found that:

1. 1. The Millennium Project is feasible and likely to be helpful to many institutions in examining and resolving policy issues at several levels. An overview of the project design and objectives appears in Section 2 of this article.

2. 2. Organizations that have an issues scanning function, or have a mandate to keep abreast of a broad range of futures thinking, have a need for access to a non-political, scholarly, and international system of future studies. Such organizations have requested continued participation in the second and third phase of this feasibility study, as well as establishing formal relations with the full Millennium Project.

3. 3. While several questions remain, the design features of a system to collect judgments using the Delphi process that were suggested by the international panel (outlined elsewhere in this report) form a straight forward operational system. Among the remaining questions are the design and use of international information systems and data bases, integration with quantitative techniques such as system modeling, the requirements for special study teams, and institutionalization and financial support. The design of the operational system is described in detail in Section 3 of this report.

4. 4. Cost estimates have been made for establishing international panels and collecting and analyzing information they provide using the Delphi process. Several assumptions are required. If a maximum of four topics are addressed in a particular year, each of the four panels consists of 150–200 people, the staff is kept to a base of three people with an additional 1.5 per panel, and advisors are paid an honorarium of $1.500, then the cost of this element of the full scale Project is likely to be approximately $900,000 per year. While communications modes are important in terms of timing and information access, the costs of communications are the smallest of the Project's cost elements. Detail of our cost estimates appear in Section 7 of this report.

This is not the final feasibility study report, but only a report on part of Phase I. As such, it contains our initial findings about how the Project might be organized. We welcome comments from the reader. Please consider this as work in progress.     

ICP 1980—A BRIEF ACCOUNT FROM AUSTRIA

This paper discusses Austria's experiences in connection with the 1980 round of the UN International Comparison Project, in which comparisons were first made within regions and the regions then linked. Austria played a dual role, as (a) the linking country between Group I (the European Community) and Group II (selected middle and eastern European countries), and (b) the base country for Group II. The paper consists of two principal parts. The first part reports, at the 3-digit commodity level, on the success achieved in finding comparable items, both within Group II and between Austria and Group I. The second part discusses a number of methodological problems that were encountered in carrying out the comparison. Chief among these was the treatment of social services that are marketed in some countries and provided free of charge or at nominal prices in others. Other questions touched upon include the treatment of output for own consumption, rents, drugs and medicines, and tourist expenditures.     

The three webs: an attempt at an understanding of the future

This article poses questions about the significance of increased internationalization of science which has developed since the cold war. It deals with three different aspects of present-day science: particle ptpsics, nanotechnology and space exploration. In a simple way, research can be divided into three different froms: information (which, by definition, I call public), knowledge (that is, covered by intellectual property rights (IPR)) and training. Further, I assume that innovation is commercial and thus has a profit motive, in contrast with the scientific goal of enlarging our view of the universe. There is, however, a more fundamental issue which is the realization that the type of accounting economy we have is too naive to develop our society further. Consider figures form the US Department of Commerce-if research is one cost unit, engineering to protogpe is three and full production 20, or even 50 for pharmaceuticals. These figures indicate the present importance placed on rates of return on capital in assessing the effectiveness of research.     

The Econometrics and Economics of the Employment Effects of Minimum Wages: Getting from Known Unknowns to Known Knowns

I discuss the econometrics and the economics of past research on the effects of minimum wages on employment in the United States. My intent is to try to identify key questions raised in the recent literature, and some from the earlier literature, which I think hold the most promise for understanding the conflicting evidence and arriving at a more definitive answer about the employment effects of minimum wages. My secondary goal is to discuss how we can narrow the range of uncertainty about the likely effects of the large minimum wage increases becoming more prevalent in the United States. I discuss some insights from both theory and past evidence that may be informative about the effects of high minimum wages, and try to emphasize what research can be done now and in the near future to provide useful evidence to policy‐makers on the results of the coming high minimum wage experiment, whether in the United States or in other countries.

Poor Women Survey Poor Women: Feminist Perspectives in Survey Research

This essay examines how applying feminist principles in scientific inquiry changes both the process and the results of research. Overall, I find that including feminist perspectives improves research. Involving a women's community in the research process and allowing poor women to interview poor women may reduce interviewer bias, improve response rates and facilitate trust in answering questions that are often quite sensitive. Including poor women in the interviewing process also enables these women to learn about scientific inquiry and to participate in the research process.     

The state of Portuguese research in economics: an analysis based on publications in international journals

In this paper I analyze the state of Portuguese research in economics based on publications in international journals for the period of 1986 to 2000. I find that scientific production is increasing but productivity remains low. I also provide a revealing characterization of the production habits of Portuguese researchers by answering the following questions: where do Portuguese researchers publish? who are the most active publishers? how often do they publish? how much do they collaborate? what is their background? Finally, I analyze the impact of that research based on citation counts.Received: July 2001, Accepted: November 2001, Mathematics Subject Classification: A10, A14I would like to acknowledge the helpful comments of the Editor, Paulo Brito, as well as Ana Rute Cardoso, Clara Dismuke, João Santos Silva, Octávio Figueiredo, Pedro Pita Barros and Pedro Portugal.

Future issues of science and technology

The Millennium Project involved 237 scientists, futurists, and policymakers around the world in a two-round Delphi on the future issues of science and technology (S&T) over the next 25 years. This is the first of a 3-year study. The study began by asking science attaches to Washington, DC, what questions were worth asking to their leading scientists and issues that were important to explore on an international basis. A series of questions were identified and rated. Actions to address the questions were also suggested and rated. The results are presented in this paper with some regional differences discussed. The next year of the study interviewed S&T policymakers for the management and policy implications of these findings, and the third year developed scenarios based on these implications.     

Estimating the economic benefits of acidic rock drainage clean up using cost shares

This paper reports the results of a stated preference study that estimates the economic value for cleaning up acid rock drainage in Colorado's Snake River watershed. In contrast to much of the existing literature, the present study emphasizes benefit estimation for three implementing projects rather than benefit estimation for general changes in water quality or large scale water quality policy. The focus on implementing projects delivers information that is specifically relevant to current decisions being faced in the watershed. While valuation questions in most stated preference studies present costs that have no relation to actual project costs, this study presents a new cost share approach. Project costs are estimated and then valuation questions present different local cost shares to subjects. This approach facilitates stated cost variation necessary for estimating the mean of the distribution of project values without resorting to experimentally designed, fictitious stated costs. In addition to estimating the mean value, which facilitates benefit cost analysis, the study also provides median value estimates, which provide insights into the political feasibility of these projects. Study results suggest that local cost shares on the order of 20%-40%, depending on the project, are politically feasible.     

Employer-supported training in Canada and its impact on mobility and wages

Using information on job histories and on two training questions contained in Statistics Canada's Follow-Up to the School Leavers Survey, this paper seeks to answer three basic questions: 1) what are the characteristics of the trainees?; 2) Does the receipt of employer-supported training cause an increase in the wage paid to those young workers?; and 3) Does it improve the degree of job attachment?; I find that more educated young people are somewhat more likely to be trained than high school dropouts although there is strong evidence of selectivity as employers clearly seem to support training for those that have the most “favorable” characteristics. Also, controlling for unobserved individual characteristics, I find that training has a sizeable wage impact for men while the effect is much more modest for women. Finally, results using Chamberlain (1985) fixed-effects hazard model show that the conditional probability of the employment relationship being terminated decreases substantially for trainees, which is consistent with the notion that the skills learned by trainees may have a sizeable firm-specific component. First version received: October 2000/Final version received: February 2002  I would like to thank Nathalie Viennot-Briot for excellent research assistance, as well as Claude Montmarquette and an anonymous referee for useful comments and suggestions.

SOME PUZZLING BEHAVIOR BY OWNERS OF INTELLECTUAL PRODUCTS: AN ANALYSIS

Creators of intellectual properties frequently seem to prefer "rental," or sale with restricted rights, over outright sale of the intellectual properties. Surprisingly, these individuals also seem to prefer legislative provisions forcing them to restrict purchasers' rights rather than allowing this result to be achieved through voluntary negotiations. In this paper, I examine two examples of this behavior: the sale of syndication rights for television programs and the separation of broadcast rights from synchronization rights for music in television broadcasts. The desire to restrict purchasers' rights is explained in two ways. First, I appeal to recent developments in utility theory, namely, regret theory. Second, I show that sales of intangible goods such as intellectual properties are less closely related to use than are sales of tangible goods, and that restricting rights is an attempt to enhance such a linkage. I give several explanations for using legislative solutions, although I acknowledge that further research is needed on both questions before definitive answers can be given.     

Dynamic lobbying: Evidence from foreign lobbying in the U.S. Congress

How do interest groups decide which member of Congress to target when decisions are made collectively? Do lobbying strategies change as legislation advances? Answering these questions is challenging due to a lack of systematic observations of lobbying contacts. I answer these questions using a novel data set constructed from reports submitted by lobbyists on behalf of South Korea regarding its free trade agreement with the United States for 10 years. I show that a diverse set of politicians are contacted but the timing, intensity, and strategy of lobbying contacts vary by politicians' institutional positions as well as their predisposed preferences for free trade.     

论按生产要素分配的依据

确立按生产要素分配的依据 ,首先要分清两个问题 :一是不能将价值创造和价值分配相混淆 ;二是按生产要素分配的依据不是要素价值论。按生产要素分配在马克思的劳动价值论中找不到依据 ,似乎在西方经济学的“三位一体公式”中可以找到依据。但按生产要素的贡献大小来决定分配 ,其中生产要素贡献大小的量无法确定。克拉克依据生产率递减规律 ,用边际产品收益来测算生产要素的报酬 ,存在着一系列无法解决的难题 ,因而是不科学的。按生产要素分配的依据只能是生产要素所有者的所有权在经济上的实现形式。
