On the surface, baseball cards appear to be little more than uninteresting object of child's play; yet they provide invaluable data for assessing unique aspects of the social order. They reveal much about the state of society when they were produced and the people who collected them. This paper examines the unique numbering system the Topps company developed to differentiate among the “royalty of the diamond” from 1956 to 1980. Their system assigned to each card in a set a number that explicitly designated its placement, while implicitly establishing a hierarchical ordering among the players, ostensibly based on performance. It is arguable whether the numbering system Topps developed was based on performance or the ascribed characteristic of race. The results of our work suggest that player performance, not race, was the primary factor in the assignment of “prestigious” card numbers in Topps’ system.  相似文献

Can there be scientific theories in psychology, medicine or psychiatry? I approach this question through an in-depth analysis of a typical experiment for clinical depression involving the monoamine hypothesis, drug action, and placebos. I begin my discussion with a reconstruction of Adolf Grünbaum’s conceptual analysis of what a placebo is. I then use his notion of “intentional placebo” to discuss a typical experiment using the monoamine hypothesis, two drugs, and a placebo. I focus on the theoretical aspects of the experiment, especially on the notion of causal explanation. I then raise five conceptual and methodological problems for theory construction. These problems focus on questions of the causal efficacy of placebos and drugs; ad hoc versus ceteris paribus explanations in biomedicine and psychology; and the falsifiability of the monoamine hypothesis. I conclude by pointing out the need for further, rigorous philosophical analysis concerning the possibility of theory construction in psychology, medicine or psychiatry.  相似文献

Among our official noblest virtues are truth and justice. In the sciences, officially, truth overrides every other virtue. In the law, officially, justice likewise overrides. That is neither to deny that justice should be tempered by mercy, nor that truth should be qualified by wisdom. Any discussion of law and the sciences is potentially high philosophy, the meeting ground of truth and justice. But there are also more practical concerns. How should scientific information and advice be used in the law courts? There is now a rather staid but thoroughly solid assessment of the current state of play in the United States Federal Court systems, Foster and Huber’s(1997) Judging Science: Scientific Knowledge and the Federal Courts. Far more challenging to the philosopher, the scientist and the student of jurisprudence is Sheila Jasanoff’s(1995) Science at the Bar because she enters current debates as a professed social constructionist, with a distinguished career of investigating science and public policy (Jasanoff and Jasanoff).  相似文献

In the 1990s alone, four states elected third-party governors. Walter Hickel of Alaska and Lowell Weicker of Connecticut were elected in 1990. Maine elected Angus King in 1994. And Jesse Ventura was elected governor of Minnesota in 1998. In this article, I examine these four cases in an attempt to identify the factors that contribute to third-party electoral success. I apply two models to these cases. The first model, “alternative culture,” holds that certain voters—regardless of specific context—are predisposed to support alternative candidates. The second model, “institutional context,” looks at factors such as name recognition, resources, and access to media as explanations of third-party success. I find that except for the influence of “partisan independence,” there is little evidence to support the persistence of an alternative culture of third-party voting. Rather, these four cases are linked by a context particularly favorable to these alternative candidates.  相似文献

Economists’ focus on institutions in explaining economic growth, while important, can obscure the significant role played by individual entrepreneurs and the process of entrepreneurship. The prevailing view of entrepreneurship in economics (which continues to shape prevailing public policies) centers on Schumpeter's famous concept of “creative destruction.” In the context of sustained high levels of economic growth, as in the recent American experience, I focus on a different feature of entrepreneurship—“nondestructive creation,” in which the uncoordinated contest of ideas and search for new applications of existing ideas generate growth. And this nondestructive creation should be analyzed and can be fostered.  相似文献

Individuals’ risk preferences are estimated and employed in a variety of settings, notably including choices in financial, labor, and product markets. Recent work, especially in financial economics, provides estimates of individuals’ coefficients of relative risk aversion (R’s) in excess of one, and often significantly higher. However, it can be shown that high R’s imply equally high values for the income elasticity of the value of a statistical life. Yet estimates of this elasticity, derived from labor and product markets, are in the range of 0.5 to 0.6. Furthermore, it turns out that even an R below one is difficult to reconcile with these elasticity estimates. Thus, there appears to be an important (additional) anomaly involving individuals’ risk-taking behavior in different market settings.JEL Classification: D80, G11, G12, I10, J17  相似文献

This paper develops a Vector Error Correction (VEC) model and uses the recently developed technique of ‘generalized’ impulse response analysis to test the empirical relationships in the Colombian economy between coffee revenues and a set of macro variables. We find that coffee price (revenue) shocks have exerted an important influence on money growth, inflation, and real exchange rates, and the direction of these effects are in line with some of the predictions of traditional Dutch Disease type models. The major difference between our results and the results of Dutch Disease type models arise in the effects of coffee booms on real output. We find that in the time horizon of 5 years after the boom, real output has increased in response to the effects of the coffee boom. The finding that coffee booms can result in positive long-run output effects is an important finding since it contradicts the traditional conclusion of Dutch Disease type models which envision an adverse long-run effect on output. We also find that the long-run effect of coffee booms is to reduce both current account and government deficits. These results illustrate strikingly that the term “Dutch Disease” is an unfortunately pejorative term that obscures the fact that coffee booms need not be viewed as a “disease” but as an extraordinary opportunity to strengthen internal and external balances.  相似文献

Call b your balance function at wealth W if you are indifferent between W and a 50–50 lottery with outcomes x and b(x). Given one b, u is arbitrary on one side of W but then determined on the other. Given two b‘s, u is arbitrary between the two Ws but then determined elsewhere. Additional properties of u restrict the b’s but do not ordinarily make u unique. Contradictions can occur. Given three bs, an algorithm is developed using minimal domains of definition that determines the relative utility of the W’s. If it is irrational, then the set S generated by applying all combinations of b’s to Ws is dense and u is determined. If finitely many b’s are rationally related, then S is discrete, a further algorithm determines it, the values of u on S are equally spaced, and u is arbitrary between any two adjacent points of S but then determined elsewhere. Infinitely many balance functions determine u unless they are rationally related in a uniform way.JEL Classification: D81  相似文献

Wallace Stegner has argued that land, scale, and aridness are defining characteristics of both the American West and writings about the West. Stegner’s definition is analyzed using his own works and Mark Twain’s Roughing It.  相似文献

This note re-addresses the question of the rationality of economic actors in a new setting. We examine the distribution of final course grades for a “Principles of Economics Class” in an effort to draw conclusions about rational student work effort. Based on the concepts of the opportunity cost of time, the relative reward for earning various grades (based on university codes for determining grade points) and the concept of rationality, we expect to find a greater percentage of grades at the lower end of the distribution for each grade level. We find statistical evidence that there are more students at the lower end of each grade interval than at the upper end. This result is consistent with what economists have long conjectured: students are rational in the allocation of study time.  相似文献

Water is a scarce and highly prized commodity in the arid Western states. Not surprisingly, water policy creation is very much a challenge for a number of reasons. Citizens hold multiple water values such as economic development and the protection of wildlife which are often contradictory. State prior appropriation laws are not easily reconciled with federal reserve rights and the public trust doctrine. There are multiple governmental and nongovernmental actors who work to influence and implement policy in a decentralized political system. If actors lose a policy battle in one decisionmaking arena (such as a legislature), they often try to influence policy at another venue (a court, Congress or an agency). Policymaking involves water issues that are dynamic over time. Furthermore, there are several types of water policy (distributive, allocative, redistributive and cooperative) that vary according to who pays costs and receives benefits, the level of conflict, the openness of decisionmaking to interested parties, and the level of government which dominates. Long ago, Mark Twain was correct when he said “Whiskey’s for drinking, water’s for fighting about.”  相似文献

India has a traditional community justice forum, known as the panchayat, which settles disputes, keeping them from escalating into serious problems. However, this forum is in decline, with serious consequences for Indian communities. Here we analyze how the demise of the panchayat in the Dalit (untouchable) community of Pudur contributed to serious conflicts and crime. Panchayats have been impacted by India’s democratization, economic development, and urbanization. Dalits, especially, want to be independent, equal, and economically prosperous. In Pudur these needs have disrupted collective sentiment to an extent that fulfillment of them has become difficult. That several non-Dalits live in Pudur has made panchayat success even more unattainable. Socially disorganizing forces—modernization, opposing values of equality and caste hierarchy, intergenerational frictions, and Pudur’s unique history and caste composition—have all contributed to the panchayat’s demise and social ills. Modern societies looking for innovative solutions to crime through community justice can learn from Pudur’s negative experiences.  相似文献

A Choice Experiment Approach to the Valuation of Mortality   总被引:4,自引:0,他引:4  
This paper presents an integrated framework for evaluating the reduction of several types of mortality risk using a Choice Experiment (CE) approach, a type of stated preference technique. Using this approach, we can distinguish the marginal willingness to pay (MWTP) for the amount of risk reduction from the MWTP for the opportunity of risk reduction and therefore calculate the “Quantity-based” Value of a Statistical Life. The risks in our survey include mortality risks due to accident, cancer, and heart disease. The Quantity-based VSL is calculated to be 350 million JPY (in 2002 Japanese Yen, about 2.9 million US dollars). Furthermore, we analyzed the influence of subjective risk perception and population characteristics of the respondents on their MWTP. Estimated results suggest that it is unnecessary to adjust the VSL according to the differences in the type of risk if the VSL is calculated using an adequate approach. However, adjustments for the timing of risk reduction and population characteristics are found to be significant for the execution of benefit transfer.JEL Classification: I18, D81, J17  相似文献

Several case studies and theoretical reports indicate that the structuralist concept of a constraint has a central role in the reconstruction of physical theories. It is surprising that there is only little theoretical discussion on the relevance of constraints for the reconstruction of social scientific theories in the literature. Almost all structuralist reconstructions of social theorizing are vacuously constrained. Consequently, constraints are methodologically irrelevant.In this paper I reconstruct three cases selected from social scientific theorizing. The first case is a generalization of Gross, Mason and McEachern's (1958) role expectation conflict theory, which is a qualitative theory. The second case is Cohen and Lee's (1975) quantitative theory of social conformity, which essentially utilizes the theor of Markov chains. The third case is the explanation schema of folk psychology which is one of the most important methodological frameworks in the social sciences.In all the three cases important constraints emerge. From an epistemological point of view it seems that the related constraints work as higher-order laws. In any case, purely conceptual arguments are insufficient to justify them.The three cases,mutatis mutandis, cover nearly all types of social scientific theorizing, so that in my view constraints play a crucial methodological role in the social sciences precisely as they have in the natural sciences.  相似文献

A multi-sector multi-country Numerical General Equilibrium model is used to endogenously determine the trade taxes that FTA members need to charge on non-member trade so that after the FTA is formed, FTA-member trade volumes with non-members remain at their pre-FTA level. We apply the notion of Kemp–Vanek admissibility in McMillan [McMillan, J. (1993), Does regional integration foster open trade? Economic theory and GATT's Article XXIV” In Anderson, K. & R. Blackhurst (Eds.), Regional Integration and the Global Trading System. London: Harvester-Wheatsheaf] to construct an FTA which does not make non-members of the FTA worse off, ensuring that the FTA is necessarily a building block and not a stumbling block to global free trade. We implement the path-independent welfare decomposition in Harrison et al. [Harrison, G., Rutherford, T. & Wooton, I. (1993). An alternative welfare decomposition for customs unions. Canadian Journal of Economics, 26(4), 961–68]. Results of such experiments are relevant to the current debate under the WTO's Doha Round of trade negotiations over GATT (1994) Article XXIV which evaluates the consistency of FTAs with the WTO.  相似文献

Leadership emergence and related variables in leaderless group problem-solving situations were examined in improvised problem-solving groups. Participants were randomly organized into 56 four-person groups and asked to evaluate themselves and others in each group by the Round Robin method. Evaluations were based on the “Big Five” personality traits, physical appearance, and two types of leadership. Generally, self-effacing bias rather than self-enhancing bias was dominant, and self-enhancing bias was not shown in two types of leadership evaluations. Relative variances of the perceiver, the target, and the relationship effects were 26.7, 9.5, and 28.8%, respectively. That the target effect was the lowest in several aspects of evaluations including leadership suggests low consensus among members in leadership evaluations. Also, older participants received higher credits in task leadership while no gender effects of target were evidenced. Finally, members’ evaluations on target were substantially accurate in most evaluation dimensions, contrary to expectations. The evaluation was particularly more accurate on task-leadership than that on relation-leadership.  相似文献

“What can business do to cope more successfully with terrorism?” The policy against terrorism available to business is a neglected issue in the scholarly literature especially in so far as individual firms rather than the business sector as a whole are concerned.Two sets of proposals are advanced, based on an economic analysis of terrorism. The first set discusses possibilities to reduce terrorists’ incentives to attack business premises; the second part outlines proposals designed to minimize the costs to businesses once a terrorist attack has taken place, hence reducing the impact.  相似文献

During the 1960s, Interior Secretary Stewart Udall faced controversy about enforcement of federal reclamation’s excess land law on California’s San Luis Project and the Imperial Irrigation District. The San Luis Project was a complex mix of state and federal funding and operation, and Udall ruled that excess land law did not apply to the state service area. Yet he overruled past practice on the Imperial Irrigation District and called for enforcement of land limits. This paper examines Udall’s effort to balance politics and principle.  相似文献
