As a concept in political science, “policy” has at least two quite distinct meanings. On the one hand, “policies” are often considered to be ways of doing things, decision rules—for example: “It is the policy of this office to handle requests in such-and-such a way.” In this sense policy would answer the questions “How do you do things around here?” and “What are your rules and procedures?” and may be called administrative policy. Alternatively, policies are often regarded as substantive programs, referring specifically to the content of what is being done, and not necessarily to how it is being done. Policy in this sense answers the questions “What do you do around here?” and “What kinds of problems do you handle?”
Studies of public policy—the policies of governments—often employ both meanings. Such studies explore not only what agencies of government are doing but how they are doing it, not only the content of the program and its history but its administration as well. The way a program is administered will certainly affect its content and results. Still, the two meanings should be kept distinct, since they refer to analytically separate things. This article will concentrate on the study of the content of governmental activities and will be concerned with administrative policy only insofar as it is studied in conjunction with substantive policy.
The field of public policy has as yet been left relatively untouched by the rigorous scientific investigation that has begun to characterize much of contemporary political science. Although political scientists have spent an enormous amount of time, energy, and resources studying political processes and the contexts in which those processes occur, little attention has been paid to policy studies by those in the discipline whose aim it is to apply scientific criteria to the study of political problems. A major reason for this is the obviously overt value content of public policy questions and the temptation, therefore, of any citizen, professional political scientist or not, to comment on such questions. Indeed, some in the profession would regard the solution of value questions as the major function of the political scientist. But even among those who have such a preference there may be disagreement as to the most fruitful method of proceeding. One could opt for a direct strategy of immediately engaging in value discussion and proposing reforms of one sort or another. Or, alternatively, one could take the position that careful empirical and theoretical analysis is a prerequisite to a proper understanding of the problems.
Although there is some indication of a developing interest in policy analysis by political scientists who are concerned with constructing theory, the most prevalent mode of conducting research on questions of public policy may, by and large, be characterized in the following manner.
Most studies of public policy take as their format a chronological ordering of events, often describing the beginnings and changes in a particular program up to the present time. Breaking up the program into convenient historical periods marking major changes in public policy is also a common method of presentation.
The historical approach to public policy is often usefully employed to organize a large body of material, and it provides a logical structure for the discussion of the policies under study. Whether chronological ordering of data is useful for theoretical purposes poses quite a different question. If the historical analysis suggests a trend or pattern of behavior which will then be analyzed and explained, the contribution to theory may be quite large. If, as is more often the case, a historical framework is chosen simply to order the data in some convenient way, then the justification for such an ordering lies elsewhere. The point is that historical discussions of public policy, although undoubtedly informative, may not increase our understanding of the relationship between the policy and other significant factors.
By and large, studies of public policy stress richness of descriptive detail. Generalizations about political processes or about comparable public policies are quite rare. Also, in relating our observations of any event we select some features and leave out others, sometimes quite inadvertently. One may legitimately ask, then, of any study, why certain things were described and others not—in other words, what are the criteria employed for the inclusion or exclusion of data? For the most part, in studies of public policies the answer to the criteria question would be “Because it helps to tell the story.” But why certain events rather than others? Most researchers, in fact, do have implicit theories which help them to distinguish between the relevant and the irrelevant, the important and the unimportant. To make such criteria explicit is often the beginning of theory and will certainly help the reader decide whether he shares the same generalizations and premises which the author used in choosing events to describe and situations to evaluate. There is no reason why one should have to search for or induce such generalizations from the study. If they are clearly presented by the author, the argument may center on their validity rather than their existence.
As often as not, in policy studies the legal character of the policy is at issue, including its legislative, executive, and judicial history. Other aspects of the political process are sometimes mentioned (such as public opinion and the activities of political parties and interest groups), but the legal descriptive history, including changes in the policy over time, is the more usual framework for policy analyses. Although the legal framework undoubtedly acts as a constraint on those involved in the making of public policy, its major effects will be constant for most public policies. Researchers will have to turn to other variables, such as the social, economic, and political setting, the personalities of the actors, and organizational factors, to explain variations within and among public policies.
Most discussions of public policy also have a value position, or an evaluative posture. This view may be either in favor of or in opposition to the current operation of the policy, but the latter is most often the case. In the best of these studies the author will make quite explicit what his value premises are, but occasionally these values will be somewhat hidden and implicit. From this normative position the author will then criticize the program. Often these criticisms will be interlaced in the historical-descriptive-legal narrative, but occasionally they will not appear until the last chapter or two, with possibly some mention of them in the first chapter. The study will then usually conclude with some suggestions for improvement of the program, in some cases with a list of reform measures for “solving” the problem. These suggestions for reform will normally take one of two forms. For some authors they are the sine qua non of the study, the major reason why so much time and effort were expended in the collection of historical-legal-descriptive data. For others this reform section is simply pro forma; it is expected that traditional public policy studies will have such a section, and leaving it out would slight the expectations of certain readers. Actually, given the relatively straightforward nature of this kind of study, assuming it is competently done, the section on reform may be the only section which is controversial and argumentative. If the facts are correct, the only argument left is in the interpretation of those facts, and since scientific generalization is not one of the stated goals of these studies, value questions fill the gap.
In addition to the above quartet of characteristics, four related observations may be made about policy studies in general.
First, in terms of policy focus, the concern of most writers is with the merits of the policy. Is it a good policy or not? Does it satisfy appropriate values? Is it administered fairly? Is it comprehensive? Are the funds spent too large or too small? By and large, political scientists who are interested in explaining how and why policies develop the way they do have attempted to shy away from these kinds of questions. It is not that these are not questions which all citizens should be asking themselves but rather that they are inappropriate questions for a scientific discipline to be asking of its own data.
Second, in terms of approach, the research is problem-oriented, in the sense that the authors speak of problems to be solved with appropriate policies. Again, problem solving of this type is an appropriate form of behavior, but not necessarily for professional political scientists as opposed to political actors. To think in terms of solutions to problems is to direct one’s energies away from discovery (the hallmark of the scientific enterprise) and toward a way of doing things which may not be realistically related to the data being studied. How often political scientists propose reforms which are not feasible because they do not square with political realities!
Third, the research is action-oriented in that political scientists doing policy studies often would like to have an impact on the policy to which they address themselves. It is not only their fellow colleagues for whom they write—it is governmental decision makers and opinion leaders as well. It may be more useful, however, for those analyzing public policies to provide as much information as possible on how various aspects of the policy are related to one another, what interests support and oppose the policy, and how the policy is related to the institutions of government and the informal governmental processes, and to leave the activist political role to the decision makers and those whose interests are clearly affected by the policy.
Fourth, in terms of research design, the research is often on a single policy, a case study. The pitfalls of case studies for theory building are well known, but since traditional studies of public policy are problem-oriented and action-oriented, and focus the debate on the merits of specific policies, the case-study format is perfectly appropriate to the aims of the researchers. But for those interested in developing a scientific inquiry, alternative research designs may be more desirable.
Although these observations are meant to be descriptive of most policy studies, there have been departures from this format. For example, there have been several recent efforts to think about the future in certain policy areas. Rather than being concerned with past policy failures, these studies attempt to delineate expected problems sometime in the future, often based on hypothesized trends of certain data. Studies of the population explosion and what to do about it, nuclear strategy, natural and human resources, automation, and other problems have captured the imagination of some researchers. Unlike traditional studies, they are not as concerned with past or even present problems. Their major concern, rather, is what the world will be like x number of years hence and possible steps which may be desirable given certain developing problems. However, these studies, too, tend to be problem-oriented single cases differing from most traditional studies primarily in their extensive speculations on the future.
The objectives of science, in any discipline, are relatively straightforward. If one is to have some measure of control over his environment, whether that environment is physical, social, economic, or political, he needs theory that is based on empirical generalizations which, in turn, subsume particular facts. The greater the array of facts subsumed, the more general the theory and the better the understanding of the causal nature of whatever phenomena are being discussed. Science clearly aims at theory construction; and where theory has been developed, manipulation and control—engineering, if you will—have not been far behind. Clearly, the ability of economists, for example, to have as much impact as they do in advising decision makers about the economy is in no small measure due to the development of theories in that field which specify, more or less accurately, the causal mechanisms which influence the economy.
Let us define “theory” as a logically related set of empirical propositions; let us define “empirical proposition” as a statement which relates one variable to another; and let us define “variable” as a concept which may assume different values. If we employ these definitions in the field of public policy, certain considerations are raised in terms of research strategies.
At the minimum we need to transform policy from a constant, an unvarying concept, to a variable. At the present time, for example, it makes little sense to assert that “the more the x policy, the more the y,” or “the more the y, the more the x policy.” “Policy” is simply not a word which has, as yet, achieved the status of a variable.
Traditionally, one possible first step in developing variables is developing typologies, classifications, or taxonomies. A typology (or classification or taxonomy) is a set of concepts or categories which differentiate among various kinds of a higher-order concept. For example, at a very simple level, a typology of a concept like “government” might be “dictatorship” and “democracy.” One may then ask a number of questions about such a typology—for example, whether the categories are exhaustive and/or mutually exclusive.
At a slightly different level, it is also possible to define a typology as a measure of a concept at the nominal level of measurement. When it is viewed as a measurement problem, one can then ask additional questions, such as whether the typology has validity and reliability, and whether operational definitions are easy or difficult to construct.
Once a typology has been constructed, it may then be possible to go further, to inspect whether an underlying factor is present which could move the typology from discrete categories to a continuous variable (increase the measurement power from nominal to ordinal or interval). If one can move in this general direction, it becomes a good deal easier to talk of theory building. However, it would be quite possible to solve all of the problems of measurement, reliability and validity, and in-clusiveness and mutual exclusiveness, and still not have contributed much to theory. The next problem to be solved is whether the categories successfully differentiate other phenomena. That is, can the categories be related to some other set of categories in such a way that relationships can be observed which might then achieve the status of theory?
Fortunately, some efforts have been made in this direction, although for the most part in a very primitive way. At a level quite close to the data, researchers have distinguished among policies in terms of their substance (agriculture, labor, education, foreign policy), the institutions making them (legislative, judicial, administrative), the target of the policy (businessmen, Negroes, lower class), time periods in which policy has taken form (ante-bellum, post-depression, prewar, Eisenhower years), ideology (secular, capitalist, first amendment, liberal, conservative), values (good, bad, dangerous), extent of support (consensus, divisive), and governmental level (national, regional, local, metropolitan).
Each of these categories is at a very low level of generalization, and unfortunately very little comparative analysis has taken place within each category. That is, labor policies are seldom contrasted with education policies, national policies are infrequently compared with city policies, etc. Instead, the categories generally are used merely to delineate an area of discourse.
At a somewhat higher level of abstraction, public policies have been differentiated in terms of style versus position issues, symbolic versus material issues; and policies have been categorized as distributive-regulatory-redistributive, areal-seg-mental, and collective-private. These distinctions have been useful in developing rather interesting empirical generalizations about how political processes differ, depending upon differences in kinds of policies. For example, it is suggested that political party preference varies more by position issues than by style issues (Berelson et al. 1954, chapter 9); that the interests of organized groups in tangible resources or in substantive power are less easily satiable than are interests in symbolic reassurance, or that the most intensive dissemination of symbols commonly attends the enactment of legislation which is most meaningless in its effects upon resource allocation (Edelman 1964, chapter 2); that political processes themselves will vary, depending upon whether policies attempt to distribute, regulate, or redistribute advantages and disadvantages (Lowi 1964); that policies which affect a whole community are more likely to be successful in homogeneous than in heterogeneous communities, and policies which affect only a segment of a community are more likely to be prevalent in heterogeneous than in homogeneous communities (Froman 1967); and that groups are much more likely to be organized successfully around private than around collective advantages (Olson 1965).
A next step, after developing categories by which different kinds of policies may be compared, is to construct hypotheses in an independent-dependent variable schema. By and large, in the policy literature to date, policies have been treated as dependent variables or outcomes of the political process. For example:
(1) The system of electing the president by the Electoral College tends to favor “liberal” interests.
(2) Apportionment of state legislatures on bases other than population tends to have a “conservative” bias.
(3) Political activities of elites will tend to have a greater pro-civil liberties bias than will political activities of nonelites.
(4) Wealthy, industrial nation-states are more likely to have stable democracies than are poorer, agricultural states.
This use of policy as a dependent variable or outcome need not be its only use, however. It is just as possible to treat policy as an explanation of other phenomena, that is, as an independent variable. One could ask whether different kinds of policies help to structure different types of political processes. At an intuitive level this seems quite plausible, but there has been little or no research into the problem.
Comparative research is also a prerequisite to theory building. Case studies are useful if information about a particular policy is desirable, or if one wishes to explore possible relationships among a wide range of variables. But case studies are manifestly not useful for testing hypotheses or for rigorous theory building. For this, comparative data is essential. Studying two, three, or many policies simultaneously would mean sacrificing factual detail, but it would greatly enlarge the scope of the inquiry and would allow the separation of the unique from the similar.
Once one has constructed variables in a comparative framework, empirical generalization with expanded validity may then take place. These generalizations may be about differences as well as similarities. For example, one may observe that direct federal aid to schools in the United States has, in the last thirty years, proceeded from graduate schools to colleges, and finally to secondary and primary schools. Interestingly enough, racial integration has proceeded in the same order. How does one explain these common patterns? Are there also differences? Are there other policies which exhibit the same pattern? Are there policies which indicate an opposite pattern? If so, how does one explain these differences?
At this point it becomes quite possible to speak of theory construction in the field of public policy. Once variables are identified and placed in an independent-dependent variable framework, comparative data collected and generalization undertaken, placing generalizations in a rigorous logical framework is certainly a possible next step. Given the time and resources which have been trained on political processes in the last twenty years, there is, therefore, no reason to believe that policy analysis cannot assume its rightful place as an important and necessary part of political theory.

Public policy refers to a set of interrelated decisions governments make to select goals where the market is not working. Governmental officials establish laws and institutions to correct the perceived problems in a continual process that involves elected officials, governmental employees, lobbyists, and public-policy experts. As social scientists developed more methods and tools, both law and public-policy analysis, originally conceived of as a branch of political science, expanded to include all social scientists, but in the twenty-first century public-policy analysis is dominated by lawyers and economists.
Public policy is the making of governmental rules and regulations to benefit not one individual but society as a whole. It asks, what is the best way to conceive and evaluate policies aimed at the public as a whole and its various subgroups? Who benefits? How much does it cost? It runs through a political process, but economic, social, legal, and psychological influences help determine the possible choices and measured impacts. Often, the results of a public-policy choice are measured in statistical terms so as to seem as objective as possible.
According to Thomas A. Birkland (2005), consensus is lacking on a more precise definition of public policy. Birkland outlines several possible definitions of public policy, always starting with the actions of government and the laws and appropriations that determine those actions. Birkland then indicates that the elements common to all definitions of public policy are: (1) It is made in the name of the “public”; (2) it is generally made or initiated by government; (3) it is interpreted and implemented by public and private players from corporations and nonprofit institutions; and (4) it also includes what the government chooses not to do.
While the study of politics has a long history, the systematic study of public policy, on the other hand, can be said to be a twentieth-century creation. It dates to the Progressive Era, when early social scientists began to recommend and rank possibilities for solving public problems. Then public policy included policies having to do with crime, poverty, health, education, and foreign affairs. Later it expanded as problems changed, and by the close of the twentieth century also included policies bearing on energy, the environment, defense, sex (e.g. same-sex marriages, sexual education and the like), and other social welfare issues. It is difficult to conceive of a united “department of public policy” because it is interdisciplinary by its very nature. It also expands beyond social science to the formation of policy objectives that are value laden. Scholars and researchers from a wide range of disciplines use different tools and methods. It takes a skilled social scientist to explain clearly a complex program such as Medicare to decision makers and other parties in the public-policy debates.
Marilyn Moon (2006), though, offers one of the best such explanations by explicitly, systematically, and logically describing and analyzing a public-policy program that offers what the market fails to do: health insurance for an aging and disabled public. Policy makers are wholly confused about how the program works and what alternatives are available to them. Moon’s book creates a primer by translating social science research into public policy. She is an applied economist who understands perhaps the most complex public-policy program in the United States, both as a matter of law and governmental practice. Her interdisciplinary analysis examines the alternatives of a national program that must work through the states and reach people on the local level. She clearly lays out criteria for evaluating the current Medicare program and how well it is working.
Since the biggest United States public programs are defense, Medicare and Medicaid, crime prevention, and education, she sets a high standard for describing and analyzing these other billion-dollar allocations. For example, nearly every nation-state has an organization to defend itself from foreign threat. But how best is this organized? Most nation-states, and even some subgroups, have an army and air force. But how should these forces be paid for (economics), organized from members of the population (sociology), positioned (geography), related to the legal system (law), dealt with in terms of individuals of the nation or subgroup (psychology), and best measured as to its effectiveness (statistics)?
Yet because the subject matter that fits into the category of social sciences evolves in parallel with societal changes, new fields of study, issues, and concepts will be added, such as the ethics of censorship, the value of income distribution, proper support of the arts, public sanction of same-sex marriage, and the psychological and economic aspects of helping people age with dignity. But all vexing policy problems require more than social sciences can deliver. They involve value judgments.
Usually the different avenues contemporary public policy takes are determined by the problems of the day. For example, as the late twentieth century spawned a whole new batch of medicines, nation-states and subgroups had to figure out how to handle health care in different ways. One can have a national system of health care delivered and paid for in any number of ways. These usually range from each person who is a member of the nation paying for his or her own care to insurance by corporations to governmental units handling the needed tasks. Most often it is some mixture of systems in flux.
How do social scientists communicate new approaches to public policy? There are the usual books and journals. But key are conferences that bring scholars of different social sciences together. A conference on aging issues might include not only social scientists but also medical researchers, operators of assisted-living facilities, and a plethora of experts to discuss ways to coordinate research efforts on policy opportunities and reform agendas.
These conferences might be funded by the National Institutes of Health and other national agencies, state agencies on crime prevention, or local schoolteachers and administrators. Public-policy agencies on a national or international level can offer and pay for conferences that no single group can afford. So, for example, all nation-states want the best tools to prevent disease. In the United States, this is done by the federal government’s National Institutes of Health, or NIH. It does some of its own research on a campus in Bethesda, Maryland (just outside Washington, D.C.), and by making grants of money to university researchers. Profit-seeking corporations usually do little of this basic research because it is not a profitable investment.
We can rank public-policy commitments by the amounts of money spent. In advanced capitalist nations, these commitments prominently include defense, social insurance, health care, and education. Defense and social insurance are usually provided collectively by the nation, while education is far more fragmented, usually at the local and state level in the United States. Health care is an issue everywhere, for it is evolving as the possibilities of cures and prevention increase.
The policy process (and the input of public-policy experts) depends of the degree of democracy of the nation-state. If some form of democracy is in play, then lawmakers at the federal, state, and local levels are voted into office and asked to make public policy that is best for their constituencies. But in more autocratic nations, the decisions are simply made at the top and implemented. At the beginning, this seems easy because basic needs for the whole are paramount. But as these policies are translated into practice, it becomes far more difficult because special interests lobby for laws and policies they claim are best for the whole but also (less articulated) best for them as a group.
In the twentieth century schools and departments of public policy in universities have developed. They usually take the form of an interdisciplinary center for social science applications to government, education, health, social welfare, and the like. Most major research universities have a school of public policy. It usually contains a core of tenured faculty, but the majority of the faculty is drawn from allied departments such as economics, sociology, psychology, and political science, as well as from medical and law schools. Many public-policy analysts earn a Master of Public Policy (or a Master of Public Administration) in such programs, while others earn specialized degrees, such as an MEd for specializing in educational policy or an MSW for specializing in social welfare policy.
Trained graduates can go to work for governments, lobby organizations (such as AARP’s Public Policy Institute, headquartered in the nation’s capital), advocacy groups (such as the Medicare Rights Center in New York City), or think tanks such as the Brookings Institution and the RAND Corporation. Later, usually with experience, they can return to teach at universities such as Harvard, Michigan, Wisconsin, and the University of California at Berkeley, to name but four of the more notable and sizable public-policy programs.

A principle that no person or government official can legally perform an act that tends to injure the public.
Public policy manifests the common sense and common conscience of the citizens as a whole that extends throughout the state and is applied to matters of public health, safety, and welfare. It is general, well-settled public opinion relating to the duties of citizens to their fellow citizens. It imports something that fluctuates with the changing economic needs, social customs, and moral aspirations of the people. Public policy enters into, and influences, the enactment, execution, and interpretation of legislation.
