Pluralism and elitism are the two prevailing theories of policy making in the United States. The purposes of this article are to suggest an alternative framework linkage political economy and to evaluate that framework against both pluralist and elitist policy explanations. The evaluation will take place within the medium of a case study on housing policy. The linkage political economy framework addresses some of the weaknesses evident in both pluralist and elitist studies of public policy. For example, in the housing policy field, elite theorists assert that policy making is dominated by a cohesive, politically powerful corporate bloc made up of the construction, finance, and realty industries.I But the elite theorists are then hard pressed to explain policy failures of this dominant coalition such as the passage of the 1937 public housing program or the original low-income thrust of the 1949 urban redevelopment program. On the other hand, pluralist analysts find a much more open and balanced policy process with a wide spectrum of interests able to be heard through multiple channels available in a decentralized political process.2 Yet, this pluralist analysis cannot adequately explain the consistent bias in U.S. housing policies and out-
This paper is concerned wth the classic "guns versus butter" dlemma.There are two countries engaged in an arms race.The first country is a decentralized market economy and the second country is a command economy.This asymmetry might capture the difference between West and East.The government of each country maximizea the life-time utility of the representative consumer, which depends upon conaumption, leisure and defence.Defence is a characteriatic, which depends positively upon the own weapon stock and negatively upon the foreign weapon stock.The government of the first country usea distortionary taxes on labour ncome to finance the provision of public goods, whereas the government of the second country simply commands its constituents.This paper contrasts coordinated and decentralized decision making.It is argued that coordinated policiea lead to lower levels of government spending and arms accumulation.As far as decentralized decision making is concerned, it is crucial to distinguish between openloop, general closed-loop and subgame-perfect Nash equilibria.The openloop Nash equilibrium relies upon pre-commitment to an announced path of ~This paper was presented to a Meeting of the European Public Choice Society, April 2-5, 1986, Noordwjkerhout, The Netherlands and to a Conference on International Economic Security organized by the Centre for Economic Policy Research, June 19R6, London.The authors are grateful to the participants of those meetings for their comments and to A. Markink for excellent computational assistance.government spending and is the solution concept moet frequently used in the literature.The problem with this concept is that it relies upon very restrictive i nformation sets and over-eatimates the inefficiencea generated by the arms race.The closed-loop Nash equilibrium allows each country to have knowledge of current and past weapon stocks.Within this framework it is possible to model threata, which can induce cooperative behaviour.The principle of subgame-perfection gves uniquenesa and credibility within the class of closed-loop Nash equilibria.This subgameperfect equilibrium coincides with the open-loop equilibrium when utility is separable in home and foreign weapon stocks.In general, this is not the case and subgame-perfect equilibria typically lead to less arms accwnulation than open-loop equilibria.This i llustrates that i n a gametheoretic context an increase in information can make both countries better off and countries should therefore be encouraged to monitor the weapon stocka of their rival.The results are illustrated wth a numerical example based upon CES utility functions and linear technologiea.This gives an opportunity to test a recently developed algorithm for the calculation of aubgameperfect equilibria i n dynamic gamea.
This paper focuses on the impacts of oil revenues on government fiscal policy when we have externality of human capital in economic. Therefore, we devised a fiscal policy capable to make the decentralized economy to achieve the first-best equilibrium in the Uzawa-Lucas model. The results of this paper show that optimal policy requires making use of a subsidy to investment in human and physical capital. Human capital can be financed by oil revenues and tax on labor income and physical capital can be financed by oil revenues. Government size dependent to oil revenues: When share of oil revenue in GDP or ratio of oil revenue in physical capital increase, government size increases and conversely. The results show the return on the physical capital must be free of taxes, but tax on labor income needed to balance the government budget in the steady state or in the transitional phase.
The health care industry is characterized at its core by the requirement that the organization and financing of services recognize the concept of need for health care. This requirement is reflected in industry characteristics of market failure, professional dominance of physicians, and public concern with equal access to care. While market failure is decreasing as a result of the emergence of insurance companies as the "new consumers" of health services, physician dominance and concerns for access continue to be strong. These characteristics mean that successful health care organizations will be local-market focused, decentralized, and tied to community cultures. With regard to training of health services administrators, education should be strengthened in the area of strategy development, with appropriate recognition given to the distinctiveness of the health care industry.

History as Ghetto. One crucial question posed by contemporary cultural theoreticians from Louis Althusser to Fredric Jameson has to do with the specific relation of cultural artifact to historical truth. How is one to account for the disparity between history and its representation, or between history and its lack of representation by hegemonic groups that have a stake in maintaining an official story? More pertinent for film scholars, how do the events on the film screen explicate-how are they explicated by-events on the larger, cultural stage, when both arenas are as much defined in the gap as in the praxis? Jameson states the problem and its necessity in its most accessible form: It is in detecting the traces of that uninterrupted narrative, in restoring to the surface of the text the repressed and buried reality of this fundamental history, that the doctrine of a political unconscious finds its function and its necessity.' When speaking about the cultural role of the ethnic, historians derive a number of possible, practical consequences of the problematics of political nonrepresentability. For some, the absence of ethnic or subculture representation in history and criticism is lamentable, but correctable (Lary May's Screening Out the Past). For others, the absence of overt subculture representation is proof of either the sterility of the mainstream culture (Michel Foucault), or the impotence and final incommensurability of ethnic cultures (John Cuddihy's Ordeal of Civility), depending on the critic's allegiance or particular neurosis. When addressing American film, it is possible to make a different kind of assertion: the absence of direct, proportional representation of the immigrant as complex character and lead player, and the substitution instead of ethnic stereotypes, is interesting when one takes into account that the medium is to a great extent dominated by immigrants and children of immigrants. The consensus among most historians of American film, from Louis Jacobs to Lary May, is that the number of immigrants-and their children, America's new ethnics-who worked in Hollywood in creative, technical, and economic capacities has been and continues to be extremely disproportionate.2 Of the thirteen founders of the Big Eight studios, for example, eleven were born outside the United States. The last two, Harry Cohn and Jesse Lasky, were the son and grandson, respectively, of immigrants.3 Add to this the fact that by
A Health Sector Financing and Expenditure (HSFE) survey was conducted in Swaziland against a background of growing concern about resource constraints on policy implementation. It sought to provide basic financial information which could be used when discussing policy options for addressing these constraints. Under a wide definition of the health sector, expenditure in 1984/85 was found to be equivalent to 9.8% of GDP and E73 ($US35) per capita. Recurrent expenditure dominated sectoral expenditure, at 86.7% of the total; 57% of recurrent expenditure was for primary health care (PHC) activities, but only 17.9% for the core preventive programmes which the policy emphasizes. Moreover, the Ministry of Health's own expenditure was biased in favour of curative care. Out-of-pocket payments largely supported general PHC activities and the core programmes were predominantly funded by foreign aid. Policy calls for increased PHC funding, therefore, are justified on the grounds of existing inappropriate allocations. If this is to be achieved there must be improved efficiency of resource use within services and improved coordination with other sources of finance in the sector. It is especially important to address efficiency issues within the Ministry. Particular attention should be paid to strengthening the role and effectiveness of decentralized management structures in resource allocation. The Ministry should also address concerns about the quality of care provided by its services, especially the poor availability of drugs. Increased PHC funding may, further, be made possible through the recruitment of additional finance. More discussion of alternative financing arrangements is necessary, but their efficacy may be dependent on improving the quality of care provided within public facilities.

A Perfect Zero-Knowledge interactive proof system convinces a verifier that a string is in a language without revealing any additional knowledge in an information-theoretic sense. We show that for any language that has a perfect zero-knowledge proof system, its complement has a short interactive protocol. This result implies that there are not any perfect zero-knowledge protocols for NP-complete languages unless the polynomial time hierarchy collapses. This paper demonstrates that knowledge complexity can be used to show that a language is easy to prove.
In its 1987 decision in Martin v. Ohio,' the United States Supreme Court again engaged in lawmaking for burdens of proof. Although the Court ratified the state's rule in this case,2 the Court has, in the past, prescribed different rules as requirements of due process.3 The Court has justified its lawmaking by asserting that the burden of proof should apportion the risks of error in a way that favors the more important interests at stake in the trial.4 If an erroneous finding of fact F would harm one set of interests more than an erroneous finding of not-F would harm the other, the burden of proof should lie with the party who alleges F, and the standard of proof for F should be high enough to reduce the risk of an erroneous finding proportionately. This idea is founded in Bayesian decision theory,5 in which it is formalized as a rule for choice in conditions of uncertainty. It is a cornerstone of the Court's
Establishing a system of family practice clinics with physicians from its medical staff enabled Mercy Hospital Medical Center, Des Moines, IA, not only to meet consumers' changing needs and wants but also to develop a long-term strategy for survival. The joint venture, which has grown to 9 clinics and 30 physicians since its inception in 1983, does not restrict the hospital from entering into similar relationships with other physician groups. Neither does it restrict physicians from entering new arrangements or using other hospitals. Each clinic operates quasi-autonomously in serving its own patients, and issues such as hiring, firing, hours of operation, and local public relations are handled in a decentralized manner. Other matters--insurance coverage, marketing programs, accounting and data processing systems--are standardized throughout the organization. Challenges involved in undertaking such a project include overcoming resistance from employees, building public awareness of the project, and creating an open, trusting relationship between physicians and administrators. It is particularly important to foster the support of physicians "outside" the partnership and to include those who remain in private practice in marketing efforts.
A solution to the following fundamental communication problem is presented. Suppose that n tokens are arbitrarily distributed among n processors with no processor having more than K tokens. The problem is to specify a bounded-degree network topology and an algorithm that can distribute the tokens uniformly among the processors. The first result is a tight $\Theta (K + \log n)$ bound on the complexity of this problem. It is also shown that an approximate version of this problem can be solved deterministically in $O(K + \log n)$ on any expander graph with sufficiently large expansion factor. In the second part of this work, it is shown how to extend the solution for the approximate distribution problem to an optimal probabilistic algorithm for the exact distribution problem on a similar class of expander graphs. Note that communication through an expander graph is a necessary condition for an $O(K + \log n)$ solution of the problem. These results have direct applications to the efficient implementation of many-to-one and one-to-many communication requests, as well as to the solution of load-balancing problems in distributed systems.
A perfect zero-knowledge interactive proof is a protocol by which Alice can convince Bob of the truth of some theorem in a way that yields no information as to how the proof might proceed (in the sense of Shannon's information theory). We give a general technique for achieving this goal for any problem in NP (and beyond). The fact that our protocol is perfect zero-knowledge does not depend on unproved cryptographic assumptions. Furthermore, our protocol is powerful enough to allow Alice to convince Bob of theorems for which she does not even have a proof. Whenever Alice can convince herself probabilistically of a theorem, perhaps thanks to her knowledge of some trap-door information, she can convince Bob as well without compromising the trap-door in any way. This results in a non-transitive transfer of confidence from Alice to Bob, because Bob will not be able to subsequently convince someone else that the theorem is true. Our protocol is dual to those of [GMW1, BC].
In this paper we demonstrate the generality and wide applicability of zero-knowledge proofs, a notion introduced by Goldwasser, Micali and Rackoff. These are probabilistic and interactive proofs that, for the members x of a language L, efficiently demonstrate membership in the language without conveying any additional knowledge. So far, zero-knowledge proofs were known only for some number theoretic languages in NP ∩ Co-NP.
RECENT STUDIES Christian ethics have uncovered a of convergence between pacifist convictions and just-war tenets. Although it is easy to assume that just-war ideas and pacifism are wholly incompatible approaches to the morality of warfare, James Childress argues that pacifists and just-war theorists actually share a common starting point: a presumption against the use of force. Childress uses W. D. Ross's language of prima-facie duties to show how pacifism and just-war thought converge. The duty not to kill or injure others (nonmaleficence) is a duty within each approach. For the pacifist, nonmaleficence is an absolute duty admitting of no exceptions. For just-war theorists, nonmaleficence is a prima-facie duty, that is, a duty that is usually binding but may be overridden exceptional circumstances— particularly when innocent life and human rights are at stake. Primafacie duties are not absolute, but place the burden of proof on those who wish to override them when they conflict with other duties, in virtue of the totality of... ethically relevant circumstances. War poses just those exceptional circumstances which the duty of nonmaleficence may be overridden. In this way Childress both highlights the point of contact between pacifism and just-war tenets and reconstructs the essential logic of the jus ad bellum. To override a prima-facie duty, however, is not to abandon it. Such duties continue to function the situation or the subsequent course of action. That is, a prima-facie duty leaves residual effects or moral traces; after overriding such a duty, our conduct must be affected by it. In the context of war, this means that the duty of nonmaleficence exerts a pressure upon the conditions and methods of war. War must be a last resort, pursued for the ends of peace, declared by a competent authority, carried out by limited means, etc. In other words, Childress reconstructs the logic of the jus bello without departing from his
The paper investigates the structure and development of planning procedures suitable for matching the needs of the road infrastructure, in relation to other transport facility requirements, with available resources. A hierarchial framework involving all parties involved in financing and providing transport facilities in which planning procedures should be developed is suggested. This involves the investigation of alternative national options through the collation and interpretation of needs derived from decentralized road management systems and from information concerning other modes of transport.
This article argues that (1) the clarity of a policy intention depends upon the appropriateness of the organizational form to implement it, and (2) the assumptions held by policymakers regarding organization form, in practice, often lead to offsetting or contradictory implementations. The study examines a major recent policy reorganization-Florida's transformation of eight autonomous human services agencies into a single department. Its avowed purposes were to integrate and decentralize services. Elmore's (1978) fourfold model is employed to assess those intentions. The findings indicated that implementation became troubled as policymakers adopted inappropriate organizational assumptions to support their intentions. The conclusions suggest that implementation had to accommodate opposing dimensions of organizational strategy and managerial structure.
