improvement of technical efficiency of firm groups abstract cooperation between firms can never improve the technical efficiency of any firm coalition the directional distance function by virtue of its additive nature is a useful tool that outlines this impossibility in this paper the additive aggregation scheme of input output vectors is generalized according to an aggregator accordingly cooperation between firms may increase the technical efficiency of the firm group this improvement is shown to be compatible with nonjoint semilattice technologies that bring out either output or input weak complementarity firm games are investigated to show that firms may merge on the basis of their inputs due to constraints imposed on outputs conversely they may merge with respect to the outputs they can produce because of limitations imposed on inputs

explaining presidential priorities the competing aspiration levels model of macrobudgetary decision making this article develops a new statistical model of trade offs among defense nondefense and fiscal policy concerns as they are reflected in the presidential budgetary process the competing aspiration levels model calm builds on crecine s 1971 great identity argument unlike most previous attempts to model presidential budgeting calm explicitly represents the interdependence of decisions about defense nondefense and totalfederal expenditures calm models this interdependence as the result of the interaction of minimal aspirations for defense and nondefense expenditures with a maximum acceptable level of expenditures from a fiscal policy standpoint statistical analyses of presidential budgets for the fiscal years from 1955 through 1980 provide strong support for the calm formulation substantively the results indicate that fiscal constraints on total expenditures have progressively weakened that the maximum acceptable expenditure level has generally exceeded the minimal expenditure aspiration level and that when a potential fiscal surplus has existed the nondefense sector has been more successful in capturing a share of this surplus than the defense sector in keeping with traditional incrementalist arguments the results indicate that previous year expenditure levels provide a relatively secure budgetary base for both the defense and nondefense sectors both sectors tend to receive their minimal aspiration levels plus a share of whatever fiscal surplus exists the analysis also indicates that the executive branch has not been as strong a direct force for budgetary growth as congress

the political economy of government domestic expenditure in the affluent democracies 1960 80 despite the large number of studies of the determination of government expenditure in the affluent democracies most students of the subject admit that we know relatively little about the complex dynamics of spending change using multiple regression analyses of changes in nonmilitary outlays over the years 1960 to 1973 and 1973 to 1980 this study attempts to remedy some of the problems in the literature by providing new tests of several old hypotheses by introducing and testing several relatively new hypotheses and by evaluating such propositions in the context of an integrated theoretical framework and of analyses that span two distinct political economic eras results suggest that the dynamics of domestic expenditure change are partially conditioned by macroeconomic and political environments of particular eras overall the self interests and ideological preferences of policymakers the institutional and extrainstitutional political action of policy relevant groups and needs for state assistance emerge as principal sources of changes in domestic expenditure

an alternative approach to understanding budgetary trade offs in this paper we criticize existing research on budgetary trade offs on a number of grounds including 1 its focus on only a limited form of trade off behavior 2 its use of a modeling strategy that avoids an explanation of trade off outcomes and likely results in specification error and 3 its generally weak development of the central concept of trade off accordingly we propose an alternative methodology for studying budgetary trade offs we begin by presenting a general taxonomy of trade offs then we analyze when and where the various types of trade offs are likely to occur within the u s federal budget process finally we conduct empirical analysis of two trade off choices in the federal process that between defense and domestic spending and that between transfer spending and consumption unlike previous trade off studies our models assume that trade off outcomes will vary depending on environmental conditions foreign policy factors seem to be the key determinants of the domestic defense trade off outcome while economic conditions appear critical to the choice between transfers and consumption

technology and the demand for imports in the pure theory of international trade traded goods are generally viewed as finished products this is in sharp contrast with the fact that the bulk of world trade is in intermediate products to reconcile theory with facts a number of models of trade in intermediate products have been proposed in recent years most of these models have been used to investigate the validity of well known trade theorems in the presence of intermediate products 2 hence most of these models are rather complex generally allowing for two factors of production and two final goods as well as for one or two pure intermediate products 3 another feature common to most of these models and that is borrowed from standard trade theory is the assumption that production is nonjoint in input quantities 4 this assumption leads to a number of remarkable theoretical results but it also greatly increases the number of possible patterns of production and of interindustry flows and it thus adds to the complexity of the models furthermore if the number of goods is larger than the number of factors nonjointness leads to indeterminacy unless additional assumptions are made 6 these assumptions typically are that some goods are not produced domestically 7 or that some goods are not traded internationally 8 this further multiplies the number of possible cases and it explains perhaps why none of the models proposed so far has emerged as the benchmark model much in the same way as for

elections keynes bureaucracy and class explaining u s budget deficits 1961 1978 the determination of u s federal budget deficits and surpluses during a period of keynesian fiscal activism is modeled in light of relevant social science literatures rational choice emphases upon electoral manipulation of the economy and keynesian stabilization marxian emphases upon monopolization andfiscal control of labor militancy organizational decision theory emphases upon budgeting inertia and a number of additional thrusts from other literatures are supported by time series regression analyses of 1961 1978 surpluses deficits the final model is statistically well behaved analysis of so called high employment measures of discretionary surpluses deficits supports all interpretations requiring discretionary policy making but an indication of automatic stabilization emerges as well a focus upon executive policy making roles is suggested as one means to further theoretical integration of explanations of state macroeconomic policy

exports and labor demand searching for functional structure in multi output multi skill technologies to simplify the representation of a technological relationship between inputs and outputs a production unit s technology must typically satisfy some restrictive conditions some of them being well known in the literature this article presents new results for aggregating labor inputs and outputs in terms of restrictions on elasticities of scale and substitution these conditions are then empirically investigated in a framework that is flexible and does not lose its flexibility after separability being imposed the empirical findings of the exact approach to aggregation are found to be rather pessimistic on the possibility of providing a simplified representation

regional interests and the reagan military buildup trubowitz p and roberts b e 1992 regional interests and the reagan military buildup reg studies 26 555 567 this paper examines the political geography of american defence policy and its implications for regional studies previous studies have examined the impact of military spending on regional economic growth and development how regional political interests shape national decisions over defence policy has received far less attention in this paper we examine the political sources of regional competition over defence policy we claim that politicians judge defence policies in terms of their consequences for their states economic growth social stability and commercial competitiveness we test our model through a cross sectional analysis of house roll call voting on national security issues during the reagan years the analysis reveals that political support for the military buildup in the 1980s varied geographically and that local economic considerations were an important factor in determining

on asymptotic properties of the parameters of differentiated product demand and supply systems when demographically categorized purchasing pattern data are available we derive asymptotic properties of an estimator for supply and demand models extended with additional moments relating consumer demographics to the characteristics of purchased products we clarify the structure of a practical sampling scheme in which the extended estimator is consistent asymptotically normal and more efficient than the original estimator we provide conditions guaranteeing the asymptotic theorems hold for the random coefficient logit model of demand with oligopolistic suppliers extensive simulation studies demonstrate significant benefits of the additional moments in estimating the random coefficient logit model

the political economy of military spending in israel irior scholarly analysis of israeli military spending has focused on national security questions we present a mathematical model incorporating security threats as well as electoral cycles and corporate profits the parameters are estimated empirically the results support the idea that in israel the military budget at the margins is also employed as a political economic instrument to help manage the economy and to provide a favorable election climate for incumbents it is suggested that the political economic dynamic widely attributed to western industrialized societies may be of increasing importance in other societies throughout the world

duality theory for variable costs in joint production duality methods for incomplete systems of consumer demand equations are adapted to the dual structure of variable cost functions in joint production this allows identification of necessary and sufficient restrictions on technology and cost so that con ditional factor demands can be written as functions of input prices fixed inputs and cost these are observable when variable inputs are chosen and committed to production hence the identified restrictions allow ex ante conditional demands to be studied using observable data this class of production technologies is consistent with all von neu mann morgenstern utility functions when ex post production and or output prices are un certain

non joint technologies the hypothesis of non jointness in input quantities separate production functions is well known and it plays an important role in many areas of economics in this paper we define three additional forms of non jointness which have received little or no attention in the literature and which might be relevant for the firm as well as for the representation of the aggregate technology we characterize all forms of non jointness in terms of variable profit and joint cost functions this yields a number of restrictions which are all testable empirically the assumption that production is non joint in input quantities separate production functions inputs allocated between the different production processes plays a crucial role in many areas of economic theory we need only think of international trade theory public finance macroeconomics growth theory or traded non traded good models of international finance in fact it is safe to say that more often than not production is assumed non joint in input quantities in multiple output models little work has been done to test the empirical validity of the assumption of non jointness in input quantities samuelson 1966 studies the characterization of non joint technologies in terms of the transformation function as pointed out by hall 1973 however samuelson s results do not seem very useful for econometric work hall studies the characterization of non jointness in input quantities in terms of the joint cost function this leads to a number of restrictions which can easily be imposed or tested for and which were used in empirical work by burgess 1976 and by kohli 1981 lau 1972 1978 finally characterizes non jointness in input quantities in terms of the profit function besides non jointness in input quantities lau also examines the case of non jointness in output quantities when an input can be cracked into several outputs in this paper we define two additional cases of non jointness and we characterize them in terms of the joint cost function and the variable or normalized restricted profit function the new forms of non jointness that we define may be useful to describe technologies at the level of the firm and may be even more so at the aggregate level some may be useful concepts in other areas of economics as well such as consumer theory by distinguishing between the various forms of non jointness one obtains a number of testable restrictions on the corresponding joint cost or variable profit functions

guns versus butter the indirect link studies of the guns versus butter trade off found no evidence for the existence of a trade off in the pre reagan era see russett 1982 domke eichenberg and kelleher 1983 mintz 1989 this study extends prior research by examining not only the direct immediate effects of defense spending but also the indirect impact of arms expenditures on education spending a three equation model is specified and empirically estimated using data from 1953 to 1987 the results show no negative short term effects but do show significant indirect long term trade offs

u s technology and the specific factors model abstract this paper reports empirical estimates of one of the most popular models of internaional trade theory the specific factors model the two outputs consumption goods and investment goods and two factors labor and capital are considered labor is assumed to be mobile between sectors while capital is assumed to be sector specific assuming that the relative supplies of the two types of capital are constant through time the model can be estimated with aggregate data even though the sector specific capital stocks are not observable empirical results show that the model does substantially better than under the heckscher ohlin production structure

non parametric analysis of multi output production with joint inputs we focus on analysing cost minimising production behaviour in multi output settings we distinguish between two approaches for modelling the use of joint inputs the cooperative approach assumes cost minimisation at the aggregate firm level while the non cooperative approach assumes cost minimisation at the level of the individual output division our framework extends the existing non parametric framework for analysing single output production an empirical application to the english and welsh drinking water and sewerage sector shows the practical usefulness of our framework specifically we compare the empirical validity of the cooperative and non cooperative models for describing the observed production behaviour

influences on executive and congressional budgetary priorities 1955 1981 a reduced form equation system is used to analyze the influence of economic political and institutional influences on the budgetary priorities of the executive branch and congress during fiscal 1955 81 three related issues are considered the extent to which political and macroeconomic factors affect priorities the degree of interdependence among the components of the federal budget and between spending and revenues and differences between the executive branch and congress with respect to these issues both types of interdependence are present within both executive branch and congressional budgeting although this interdependence is stronger within the executive branch the influence of economic conditions on budgetary outcomes is strong but varies considerably across spending categories there is no evidence of apolitical business cycle political variables exert a modest influence on the budgetary outcomes examined differences between democratic and republican budgetary policies as well as differences in the budgetary priorities of different presidential administrations are small by comparison with the differences between executive and congressional policies

change and stability in superpower rivalry we investigate the dynamics of superpower rivalry participants in policy debates within each state use information about expected future threats and economic costs to influence other policy actors and this process of sophisticated reaction links the security policies of these two states into a single rivalry system analysis of vector autoregression models of u s and soviet military expenditures and diplomatic hostility and u s gross national product supports the hypothesis that these policies approximate the behavior of unitary rational states capable of forming rational expectations of each other s future behavior the dynamic response of this system to a wide range of exogenous shocks or innovations reveals the underlying stability of this rivalry system the military expenditures of both states exhibit a cyclical response to innovations with a shorter u s cycle this lack of synchronization creates several problems for analysis and for policy change

external ambition and economic performance realist approaches to international politics raise the possibility that external policies based on expanding military power may undermine the economic bases of that power the links between external strategy and economic performance can be classified as fiscal macroeconomic effects structural microeconomic and structural effects and protectionist effects on foreign economic policy the case of prewar japan suggests that for countries at an intermediate position in the international power hierarchy and in the international division of labor the positive effects of external ambition on economic performance may dominate other cases national socialist germany contemporary developing countries and the postwar superpowers seem to confirm that international position is a principal determinant of these effects

rent dissipation and efficient rationalization in for hire recreational fishing abstract recreational fisheries are increasingly important in fisheries management for some species recreational take rivals or exceeds the amount harvested by commercial fishermen most recreational fisheries are regulated with gear restrictions bag limits and time area closures but there is increasing interest in the market based solutions employed in commercial fisheries this despite the lack of an adequate bioeconomic theory of the joint commercial recreational aspects of many recreational fisheries this paper integrates a detailed production specification with traditional bioeconomic tools in order to better understand the implications of rationalization schemes targeted at the charter sector while confirming some of the qualitative conclusions of the commercial fisheries literature on open access and regulated open access our model also generates rich and novel predictions with respect to input choices the number of vessels and congestion externalities we devise a system of instruments that generate efficient outcomes and extensively discuss issues associated with their real world implementation

u s defense spending and the soviet estimate there is a glaring and potentially important discontinuity surrounding discussions of u s defense expenditure policy making on the one hand a growing body of empirically based research questions whether the u s reacts in any significant fashion to the military expenditures of the soviet union on the other hand defense policy makers routinely justify defense increases as a response to similar increases by the soviet union the discontinuity is resolved in the context of a multistep model of the defense expenditure policy making process that incorporates a new estimate of soviet defense spending and mass public opinion once formulated the model provides answers to the following two questions 1 does the u s insofar as defense spending is concerned react to the military expenditures of the soviet union 2 if so what is the magnitude of the reaction the answers indicate that not only does the u s react to estimated soviet defense spending but that the reaction is directly responsible for a very substantial portion of the post 1978 increases in u s military expenditures

testing budgetary theories with budgetary data assessing the risks empirical tests of theories of budgeting and the expenditure choices of governments typically involve quantitative models in which the dependent and independent variables share common components this can result in strong positive or negative statistical coefficients even in the absence of substantively meaningful relationships among theoretical concepts indeed this methodological problem together with incrementalism in budgeting often poses a potential alternative explanation for empirical findings normally taken as confirmation of other theories of budgeting and expenditure choice in this paper i present a simulation approach for testing empirical results against the null hypothesis that the results are merely a consequence of incrementalism combined with built in structural relationships among variables due to common components shared by the variables the approach is illustrated with analyses of the methodologies of two recent studies one of the welfare versus defense tradeoff in western industrialized nations and one of the state budgetary process

modeling u s budgetary and fiscal policy outcomes a disaggregated systemwide perspective this paper develops and estimates a model of u s federal budgetary outcomes that allows for considerable disaggregation across spending categories while providing through cross equation coefficient restrictions substantially more statistical power than traditional approaches we identify significant top down fiscal policy effects on budgetary allocations primarily within the defense budget budgetary responses to macroeconomic conditions are generally countercyclical although middle class entitlements appear to react procyclically to inflation political control of congress influences budgetary outcomes with democrats giving higher priority to domestic spending programs the relative rate of public sector inflation affects spending growth consistent with baumol s disease public opinion affects defense and low income entitlement spending defense spending has also been influenced by perceived soviet threat as well as the level of armed conflict there appear to be small election year effects although not of the sort predicted by political business cycle models with a few exceptions administration specific impacts are relatively small and not systematically related to the party of the president

guns versus butter a disaggregated analysis irior studies of the guns versus butter trade off have focused on total military expenditures and subcomponents of welfare spending educa tion health and housing i extend the analysis to include the major subcomponents of the defense budget the results are consistent with clayton s domke eichenberg and kelleher s and russett s findings of a lack of defense welfare trade off in the 1947 80 era but reveal very specific trade offs during the reagan years

the illusion of choice defense and welfare in advanced industrial democracies 1948 1978 research on the tendency of governments to trade off welfare spending for defense has generated diverse and often contradictory findings this study attempts to clarify the issue of trade offs by examining expenditure patterns since 1948 for the four major na to allies united states united kingdom federal republic of germany and france when viewed from the perspective of long term trends in shares of outlays trade offs are evident when short term changes in expenditure which are more germane to the potential for one spending category to benefit at the expense of the other are studied no pattern of trade off can be detected a three equation model is estimated to control for the variety of possible determining factors of public resource allocation in none of the four nations does a pattern of trade off emerge except in periods of wartime or postwar reconstruction these findings are consistent with the ability of governments to finance new spending through either increased taxes or larger budget deficits the growing disinclination to use these methods however suggests that the potential for trade offs has perhaps reappeared in the 1980s

defense expenditures economic growth and the peace dividend recent developments in eastern europe have created expectations of a peace dividend associated with reduced levels of u s defense expenditures we present and empirically estimate a two equation model for assessing the direct and indirect immediate and delayed effects of changes in defense spending on economic growth in the united states
