the specification and estimation of interrelated factor demands under uncertainty abstract this paper studies a model of the firm s interrelated demands for the factors of production incorporating exogenous variables with uncertain future values multiple quasi fixed factors depreciation in use and non symmetric internal costs of adjustment the inputs considered are production labor non production workers capital inventories of non finished goods and capacity and non production worker utilization rates a simultaneous system of factor demand equations with constraints is estimated and using u s manufacturing data the model is shown to be tractable under certain assumptions the results are encouraging given the complexity and the nature of the model

approaches and methods for the econometric analysis of market power a survey and empirical comparison this study discusses two widely used approaches in the new empirical industrial organization neio literature and examines the strengths and weaknesses of the production theoretic approach pta and the general identification method gim for the econometric analysis of market power in agricultural and food markets we provide a framework that may help researchers to evaluate and improve structural models of market power starting with the specification of the approaches in question we compare published empirical studies of market power with respect to the choice of the applied approach functional forms estimation methods and derived estimates of the degree of market power thereafter we use our framework to evaluate several structural models based on pta and gim to measure oligopsony power in the ukrainian dairy industry the pta based results suggest that the estimated parameters of oligopsony power are significantly different from zero while gim based results do not indicate any evidence of oligopsony market power in the ukrainian dairy industry moreover estimations results vary substantially due to the employed estimation procedure

analyzing the indirect production function for u s manufacturing in recent years there has been considerable research conducted in applied production economics to estimate the firm s structure of technology and its production characteristics the main concept used in this research is the duality principle relating production and cost or profit together with the use of flexible form econometric specifications for estimating production technologies under the assumption of cost minimization or proft maximization duality implies that for any production function there exists a cost or profit function that provides an equivalent description of the technology what is less well known however is that the firm s technology can be equally well described by the indirect production function a production analog of the indirect utility function in consumer theory 5 8 9 the indirect production function is based on the firm s output maximization subject to a budget constraint on input costs of course it is evident enough that a firm choosing inputs to maximize output for a given input cost produces that output at the minimum cost by implication the indirect production and cost functions are equivalent ways of characterizing the firm s technology and as will be seen there exists a unique correspondence between the two functions in empirical application however the choice between the two functions hinges on the exogeneity or endogeneity of output for the indirect production function the level of output is an endogenous variable in the case of the cost function on the other hand output is exogenously given in most situations it is the indirect production function not the cost function that is more compatible with observed behavior of firms and industries while numerous studies have been conducted recently to estimate the cost or profit function in a variety of firms and industries 1 2 3 6 no attempts have been made to employ the indirect production function as a working tool in applied production analysis this paper attempts to provide empirical evidence from analyzing the indirect production function within the context of an application of the duality principle using the well known data set utilized by berndt and wood 3 and berndt and khaled 2 it reexamines the production structure of u s manufacturing based on a translog specification of the indirect production function for the underlying technology an important question is how the choice of a model the indirect production or cost function

an analysis of technological change factor substitution and economies of scale in manufacturing industries in india the biases of technological change factor substitution and economies of scale in four major manufacturing industries viz cement electricity and gas cotton textiles and iron and steel in india are examined the translog cost functions are estimated using annual time series data covering the period 1960 61 to 1982 83 the study reveals that technical change has been biased towards the use of labour and materials and against the use of capital and energy in electricity and gas industries in cotton textiles the technological change has shown the opposity biases significant economies of sclae exist in the production of electricity and gas enough evidence of substitution possibilities among factors of production in all the four industries was also found

return seasonality in stocks and their underlying assets tax loss selling versus information explanations results of tests contrasting tax loss selling with intertemporal information variation as explanations of the january seasonal in stock returns are reported closed end fund shares display the typical size related january seasonal while their net asset values do not interpreting the net asset value return as a proxy for information about underlying assets this result indicates information variation is not a necessary condition for the january effect in stocks the share returns at the turn of the year are negatively related to their mean preceding year returns and positively related to the standard deviations of their preceding year returns these results are consistent with tax loss selling article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

sustainability aid and material welfare in small south pacific island economies 1900 1990 abstract the paper discusses the concept of sustainability and puts forward the argument that conventional notions of what constitutes economic development cannot be applied mechanistically to the very small island economies of the pacific in practice what matters is whether the entitlement of island communities to rent incomes remains sustainable this in turn requires that labor access to the modern capitalist economies of the region continues or is opened up and that the major regional powers continue to subsidize consumption levels in the small island countries unless or until those countries achieve a satisfactory level of rent income both of these conditions hinge upon the long run political commitment of aid donor governments to the welfare of island communities and on the skills of island politicians and officials in negotiating and maneuvering for access to aid funds from competing donors

future inequality in co2 emissions and the impact of abatement proposals this paper analyzes future carbon emissions inequality using a group decomposition of the gini index business as usual projections to the year 2100 for 135 countries show inequality in per capita emissions declines slowly next the impact on emissions levels and inequality of the kyoto protocol and other abatement proposals for annex ii countries in 2010 are measured with a focus on the gap narrowing and reranking effects substantial reranking of per capita emissions between annex ii and non annex ii countries will not occur unless the former reduce their emissions by at least 50 versus 1990 levels and the latter continue growing unabated

ethical influences on the evolution of the us tradable permit approach to air pollution control abstract in 1975 a novel approach to air pollution control was implemented in the usa from this rather humble beginning this approach has now been expanded rather dramatically in several different directions this paper describes this evolution shows how the design of the system has been adapted to accommodate ethical concerns and describes how the latest versions of this approach have transformed the regulatory process which spawned the approach in the first place

will markets direct investments under the kyoto protocol lessons from the activities implemented jointly pilots under the kyoto protocol countries can meet treaty obligations by investing in projects that reduce or sequester greenhouse gases elsewhere prior to ratification treaty participants agreed to launch country based pilot projects referred to collectively as activities implemented jointly aij to test novel aspects of the project related provisions relying on a ten year history of projects we investigate the determinants of aij investment our findings suggest that review agency preferences related to national political objectives and possibly deeper cultural ties influenced project selection and limited the number of aij projects bilateral ties also appear to have affected investment decisions directly possibly because of related transaction costs the results suggest an investment process different from the assumptions that underlie well known estimates of cost savings related to the protocol s flexibility mechanisms we conclude that if approaches developed under the aij programs to approve projects are retained the scale of investment under kyoto s flexibility provisions and their cost savings will be less than what is generally anticipated and the pattern of investment less driven by abatement costs

the elasticity of substitution in india s manufacturing sector abstract using cross section data and the translog cost function this paper examines the substitution possibilities between capital and materials and labor and materials since raw materials might be used to overcome the bottlenecks caused by shortages of physical capital and skilled labor three significant conclusions are a since materials are substitutable for both capital and labor to a considerable extent capital and skilled labor may not be a binding constraint on growth agricultural materials expansion may substitute for these inputs and lead to expansion in the industrial sector b fixed proportion models are not warranted in india without modification and c separability tests showed that materials must be included in the production function

estimation of the internal adjustment costs model using longitudinal establishment data this paper develops estimates of the internal costs measured in terms of foregone current output associated with the introduction of new plant and equipment into manufacturing establishments using the census bureau s longitudinal establishment data file a very large and rich source of production and investment data our estimates provide strong support for the internal adjustment costs hypothesis they indicate that one dollar increases in expansion and replacement investment cause on the average 35and 21 cent reductions respectively in current output the internal cost of adjusting to equipment appears to be higher than the cost of adjusting to plant

carbon dioxide emissions allocation a review carbon dioxide co2 emissions allocation plays a fundamental role in determining reduction responsibility at economy level or emission permits at firm level past decades have seen the development and applications of various methods for co2 emissions allocation this paper provides a literature review of co2 emissions allocation with emphasis on the evolution of allocation methods used it begins with a summary of the most popular allocation principles and criteria that lay a foundation for the development of allocation methods we then classify the existing allocation methods into four groups namely indicator optimization game theoretic and hybrid approaches the main features and findings of past studies are identified and summarized while the fairness principle prevails in earlier studies the efficiency principle has been found to receive increasing attention recently we also present a comparison of the empirical results based on ten popular indicator methods to show how indicator choice affects the allocation results issues related to selecting appropriate methods in co2 emissions allocation are finally discussed further research may be carried out to strike a balance between fairness and efficiency so that the allocation results become more widely acceptable and economically feasible

burden sharing in a greenhouse egalitarianism and sovereignty reconciled the allocation of emission entitlements across countries is the single most controversial issue in international climate policy extreme positions within the policy debate range from entitlements based on current emission patterns sovereignty to entitlements based on equal per capita allocations egalitarianism this paper shows that gradual convergence from sovereignty towards egalitarianism could provide a pragmatic solution to the equity debate when combined with international emissions trading the convergence approach stands out for offering the developing countries substantial incentives for participation in the international greenhouse gas abatement effort without imposing excessive burdens on the industrialized countries

policy reform and labour demand in branches of sri lankan manufacturing industry many policy reforms in developing countries aim to remove factor market distortions whether such reforms reduce unemployment depends partly on the substitution possibilities between labour and other factors of production this paper examines labour demand in seven branches of sri lankan manufacturing industry using data on 4 digit industrial categories over the 1990 to 1997 period the box cox transformation is used to allow for flexible and data dependent elasticities the elasticity of capital labour substitution varies widely across the branches of industry and is usually variable rather than constant the average long run own wage elasticity of labour demand for the manufacturing sector is estimated as 0 80 so factor price policy should have an important effect on labour demand in this setting

seasonal fluctuations in industrial production and stock market seasonals february and august peaks in the growth rates of the seasonally unadjusted industrial production index follow the stock market peaks documented by rozeff and kinney 1976 by one month coefficients on one month lead growth rates in industrial production for small firms are positive and significant in time series regressions even in the presence of the market factor moreover whereas returns on large firms stocks unidirectionally gran ger cause i e predict future growth rates in industrial production at least six months in advance returns on small firms stocks reflect one month lead as well as past growth rates in industrial production for these reasons we argue that seasonal real growth provides a partial explanation for the january stock seasonal among small firms

expectations and factor demand this paper develops and estimates a model of interrelated factor demand with rational expectations in the presence of internal adjustment costs invariant technological parameters are distinguished from the firm s adjustment parameters which change when the exogenous processes faced by the firm change the capital demand equation is derived by solving the euler equations which stem from minimization of the present value of costs future exogenous variables are supplied from solutions of arima equations the model is tested on postwar quarterly data for u s manufacturing a regime change in the process for energy prices is simulated as is a temporary suspension of the investment tax credit

tradeable emission permits and the control of greenhouse gases this article reiterates the case for tradeable permits as a global policy option for limiting greenhouse gas emissions and considers the detailed design of a global tradeable permit regime emphasising the importance of the initial assignment of property rights and arguing that the relevant property rights in this case are the rights of every member of the world community to share in a sustainable global atmosphere and climate the allocation of permits should therefore be done on a per capita basis across the world community with the result that rents generated by the process of reducing carbon emissions would accrue to non polluters most of whom live in the south the international transfers of income and wealth implied by the proposed scheme are large but feasible there is therefore a real prospect that an international convention on carbon dioxide emissions could end the debt crisis and finance sustainable development in the south

paying for pollution permits and charges tradeable emission permits are becoming an increasingly important instrument for controlling emissions for a variety of reasons emission permits are often allocated gratis conferring a windfall gain on the first generation of permit holders this paper examines how a regulator may capture this rent four different methods of rent capture profit output and input charges and an emission permit rental charge are compared with respect to their effects on efficiency and the relative burden placed on cleaner and dirtier firms in addition to generating revenue for the regulator certain charges coupled with emission permits may result in a better instrument than permits alone

misspecification of capital asset pricing this study documents empirical anomalies which suggest that either the simple one period capital asset pricing model capm is misspecified or that capital markets are inefficient in particular portfolios based on firm size or earnings price e p ratios experience average returns systematically different from those predicted by the capm furthermore the abnormal returns persist for at least two years this persistence reduces the likelihood that these results are being generated by a market inefficiency rather the evidence seems to indicate that the equilibrium pricing model is misspecified however the data also reveals that an e p effect does not emerge after returns are controlled for the firm size effect the firm size effect largely subsumes the e p effect thus while the e p anomaly and value anomaly exist when each variable is considered separately the two anomalies seem to be related to the same set of missing factors and these factors appear to be more closely associated with firm size than e p ratios

dividend distributions and closed end fund discounts abstract empirical support for the hypothesis that closed end fund discounts are related to overhanging tax liabilities has been mixed we introduce a new approach to testing this hypothesis by examining changes in discount levels following distributions of dividends and capital gains since distributions reduce future shareholder tax liabilities the tax liability hypothesis implies that closed end fund discounts should decline following distributions focusing on changes in discounts isolates this tax effect by eliminating the impact of other fund specific factors on discount levels our results support the tax liability hypothesis showing that short run fluctuations in discounts are directly affected by taxable distributions

international equity and differentiation in global warming policy ne of the major obstacles to reaching a comprehensive agreement on global warming is the setting of greenhouse gas emission reduction targets for individual countries long standing tensions between industrialized and developing countries have raised the issue of equity in burden sharing moreover individual industrialized nations have pleaded special circumstances and have sought differentiation in their obligations this paper analyzes alternative rules for distributing tradable carbon dioxide emissions permits a non linear programming model which distinguishes between allocation based and outcome based rules is used to analyze the relative welfare outcomes the model is applied to the world body of nations and yields several important policy implications

an econometric estimation of hicksian and marshallian elasticities in indian manufacturing the knowledge of substitution possibilities between different factors of production is essential in evaluating the impact of public policies on productivity employment industrial growth and factor intensity since the advent of flexible functional forms in the early 1970s a large number of studies have estimated the ease of factor substitution however to date most of the empirical evidence on factor substitution is based on a cost function a drawback with the cost function

the own wage elasticity of labor demand a meta regression analysis firms labor demand responses to wage changes are of key interest in empirical research and policy analysis however despite extensive research estimates of labor demand elasticities remain subject to considerable heterogeneity in this paper we conduct a comprehensive meta regression analysis to re assess the empirical literature on labor demand elasticities building on 942 elasticity estimates from 105 different studies we identify sources of variation in the absolute value of this elasticity heterogeneity due to the theoretical and empirical specification of the labor demand model different datasets used or sectors and countries considered explains more than 80 of the variation in the estimates we further find substantial evidence for the presence of publication selection bias as estimates of the own wage elasticity of labor demand are upwardly inflated

institutions and the turn of the year effect evidence from actual institutional trades abstract using a large proprietary database of institutional trades we investigate whether institutional investors drive the turn of the year toy effect institutions that engage in window dressing tax loss selling or risk shifting will contribute to the toy effect by selling small poorly performing stocks at the end of december and or buying those same stocks at the beginning of january we find abnormal pension fund selling in small stocks with poor past performance during the final trading days in december providing some support for the window dressing hypothesis however we find little evidence that institutional tax loss selling or risk shifting trading strategies contribute to toy returns furthermore stocks with no institutional trading around the year end exhibit considerably stronger toy return patterns than stocks in which institutions trade taken together our results suggest that institutions play a limited role in driving the toy effect

closed end fund shares abnormal returns and the information content of discounts and premiums closed end funds discounts contain information in the sense that they can be used to construct portfolios that earn returns exceeding those predicted by the two factor capital asset pricing model the precise nature of the information contained in a discount is not clear however this paper provides evidence that the information contained in a discount is an incomplete prediction of the fund s likelihood of being open ended profitably thompson 18 investigated the extent to which closed end funds share price discounts and premiums relative to net asset value convey useable information about future rates of return on the funds shares he found that an ad hoc strategy of investing in portfolios of stocks selling at discounts significantly outperformed the returns predicted by the black 3 two factor asset pricing model in other words closed end fund discounts and premiums do contain information about future returns in addition to that captured by the benchmark model the precise nature of the information contained in the discounts and premiums is a mystery however this paper presents and tests a model of the information content of closedend fund discounts and premiums based upon the prospects for a form of organizational restructuring known as open ending the term open ending refers to a set of techniques for forcing a closed end fund s share price to its traditionally higher net asset value converting the fund to an open end fund merging the fund with an open end fund or liquidating the fund s assets and distributing the proceeds to the shareholders while both brauer 4 and brickley and schallheim 5 have shown that actual open endings involve significant benefits to shareholders the focus of this paper is on the valuation effects of the potential for open ending the analysis shows that the probability of profitably open ending a fund should affect the fund s market value that the discount is only one element in a larger information structure about the probability of openending and that changes in this probability are not fully and immediately reflected in the share price section i introduces a straightforward model of the effect of open ending potential on closed end fund value the model provides a compact expression for

optimal stock trading with personal taxes implications for prices and the abnormal january returns abstract the tax law confers upon the investor a timing option to realize capital losses and defer capital gains with the tax rate on long term gains and losses being about half the short term rate the law provides a second timing option to realize losses short term and gains long term if at all our theory and simulation over the 1962 1977 period establish that taxable investors should realize long term gains in high variance stocks and repurchase stock in order to realize potential future losses short term tax trading does not explain the small firm anomaly but predicts a seasonal pattern in trading volume which maps into a seasonal pattern in stock prices the january anomaly only if investors are irrational or ignorant of the price seasonality

a comparison of foreign exchange forward and futures prices abstract in theory futures resettlement should create systematic pricing differences between futures and forward contracts however previous empirical studies do not demonstrate such differences in the foreign exchange markets on the other hand inferences from these studies are suspect since they do not directly implement theortical measures of resettlement effects and are unadjusted for sub gaussian data properties in this paper these limitations are addressed through the use of the multivariate autoregressive moving average model our findings provide evidence of systematic pricing influences arising from futures resettlement

evidence on tax motivated securities trading behavior tax loss selling by investors in common stocks near the end of calendar years has been proposed as an explanation for the turn of the year effect in stock returns past analyses of this hypothesis have relied on inferential data we provide here some direct data from a compilation of over 80 000 actual common stock investment round trips by a sample of 3000 individual investors we find strong evidence of a concentration of loss taking trades late in the year and milder evidence of a concentration just prior to the dates when investments become eligible for long term tax treatment the question as to whether and in what manner the impostion of a tax on realized capital gains affects the securities trading behavior of investors who are subject to the tax has been a longstanding topic of research in the financial ecomonics literature the original attention devoted to the matter was motivated primarily by a concern about resource allocation and federal tax revenue consequences and was directed toward the phenomenon of what has been termed the lock in effect of a gains tax that issue has remained an important public policy one and continues today as part of the ongoing debate about appropriate strategies for reducing the federal budget deficit particular additional interest in the topic has emerged in recent years however because securities transactions undertaken systematically for tax reasons have also been proposed as part of the explanation for certain observed anomalies in historical common stock returns most prominently the well documented turn of the year effect our purpose here is to provide some new evidence that decisions by investors as to the timing of the realization of capital gains and losses from their common stock investments are significantly affected by tax considerations this evidence indicates that a difference in the tax rates applicable to realizations classified as short and long term influences the timing of individual investors trades and further that there is a clear tendency for trades by individuals which give rise to losses to be concentrated near the end of calendar which for them are also tax years while we cannot conclude that

exclusionary manipulation of markets for pollution rights abstract strategic price manipulation can affect the distribution of transferable pollution rights across polluters and the efficiency of pollution control efforts prior research has concentrated on market manipulation by firms seeking only to minimize the sum of pollution rights costs and pollution abatement costs in this paper we explore the potential for the exclusionary manipulation of pollution permit markets intended to drive up the costs of one s rivals and we distinguish between the resource allocation effects of exclusionary manipulation and cost minimizing manipulation we find that exclusionary manipulation can sometimes worsen and sometimes ameliorate the abatement inefficiency which occurs under cost minimizing manipulation and that an overbuying rule can obviate or at least limit damages from this form of strategic behavior

capacity utilization and depreciation in use in this paper the effect capacity utilization has on the depreciation of capital goods is studied starting from a quadratic approximation to a normalized short run cost function expressions for the optimal rate of capacity utilization the demands for labour and energy and for investment are obtained investment is a function of past capital stock expected future capital stock expected future relative prices and expected future depreciation rates expectations are modelled via instruments the model is tested using us total manufacturing quarterly data depreciation dependent upon usage is found to be both statistically and economically significant

international investment restrictions and closed end country fund prices some closed end country funds trade at large premiums relative to their net asset values this paper examines whether international investment restrictions raise country fund price net asset value ratios by segmenting international capital markets we test whether a relation exists between announcements of changes in investment restrictions and changes in these ratios using weekly data from may 1981 to january 1989 the results provide evidence that some foreign markets are at least partially segmented from the u s capital market

dynamic factor demands and the effects of energy price shocks a dynamic model is used to understand how sharp changes in energy prices affect investment behavior employment and energy use the authors discuss the theory behind their model selection model specifications estimation methods and data list parameter estimates and elasticities for the selected model and describe the simulations they conclude that 1 the data strongly reject the hypothesis of constant returns to scale within their specification of aggregate production 2 the data indicate adjustment costs on labor are small and 3 their results help reconcile some of the conflicting estimates of energy demand elasticities appearing in recent literature 23 references 3 figures 3 tables

dynamic factor demands and market structure under rational expectations some estimates for the italian manufacturing system this paper deals with a dynamic model of the behaviour of firms under rational expectations the adjustment cost framework is followed to describe production technologies the objective of firms is to maximize the stream of future profits under rational expectation first order conditions for the optimum are derived with respect to input demands and one output supply the output market structure is modelled in order to test price taking behaviour the adjustment costs of quasi fixed inputs are internal and interrelated the model is estimated for the italian manufacturing system with encouraging results

differential information and security market equilibrium we propose a simple model of equilibrium asset pricing in which there are differences in the amounts of information available for developing inferences about the returns parame ters of alternative securities in contrast with earlier work we show that parameter uncer tainty or estimation risk can have an effect upon market equilibrium under reasonable conditions securities for which there is relatively little information are shown to have relatively higher systematic risk when that risk is properly measured ceteris paribus the initially very limited model is shown to be robust with respect to relaxation of a number of its principal assumptions we provide theoretical support for the empirical examination of at least three proxies for relative information period of listing number of security returns observations available and divergence of analyst opinion

functional separability and the existence of consistent aggregates in u s manufacturing comment this paper examines the relationship between separability of the direct production function in inputs and separability of the indirect production function in input prices in particular it shows that simultaneous direct and indirect weak separability implies homotheticity of the direct production function and hence homotheticity of the indirect production function thus inferences regarding direct separability based on empirical tests for indirect separability would be valid only if homotheticity is also imposed and treated as maintained hypothesis copyright 1996 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

tax loss selling and the january effect evidence from municipal bond closed end funds this paper provides direct evidence supporting the tax loss selling hypothesis as an explanation of the january effect examining turn of the year return and volume patterns for municipal bond closed end funds which are held mostly by tax sensitive individual investors we document a january effect for these funds but not for their underlying assets we provide evidence that this effect can be largely explained by tax loss selling activities at the previous year end moreover we find that funds associated with brokerage firms display more tax loss selling behavior suggesting that tax counseling plays a role among the numerous stock return anomalies probably none has generated more interest than that of the turn of the year or january effect the phenomenon in which small capitalization stocks realize unusually high returns in early january 1 the literature offers a number of hypotheses to explain this phenomenon including the tax loss selling hypothesis the window dressing hypothesis the insider trading information release hypothesis and the seasonality of the risk return relation hypothesis given existing evidence in some support for the first two hypotheses the debate continues with respect to which of these the tax loss selling of individual investors or the window dressing of

scale biased technological development in canada s industrialization 1900 1929 the relationships between factor use and scale and technological change and scale are emphasized in a translog cost function analysis of technological development in four sectors of canadian manufacturing 1900 29 by paying particular attention to the role of electrification in this technological development the major findings are that the increased use of electricity was not in general scale dependent and that electrification may have been a factor in increasing the relative productivity of smaller scale units over the period a hypothesis that states that technical change is partially induced by increased scale is however confirmed copyright 1990 by mit press

measures of capacity utilization and its determinants a study of indian manufacturing we estimate capacity utilization cu rates in for selected industries in indian manufacturing for the 20 year period 1976 1996 we estimate a generalized leontief variable cost function with capital as a quasi fixed input to derive our cu measures using error component techniques we note substantial variations in cu both across industries and over time in general we find that cu rates were higher in the earlier time period dropped in the mid 80s and started rising again in the early 90s cu rates in our analysis are sensitive to input prices with the sole exception of the price of labor we also confirm the standard result that variations in demand are a significant driving force for variations in cu we find that cu is positively related to the magnitude of labor intensity in production this holds for both between industries and within industries empirical results also indicate that traditional measures of cu such as minimum capital output ratio and peak to peak are not appropriate proxies for

the translog production function and variable returns to scale this paper examines existing methods of estimating the translog production function and provides a general framework that allows for variable returns to scale the model is based on the inverse input demand function and embeds a nonhomothetic production technology previous estimation methods are valid only for homogeneous technologies with fixed scale effects estimation results for u s manufacturing show that neither homotheticity and homogeneity nor constant returns to scale is a proper characterization of the underlying structure of production thereby vindicating the empirical relevance of the inverse demand framework that entails a nonhomothetic technology copyright 1992 by mit press

constrained output maximization and us agriculture this paper presents a framework for estimating an indirect production function and then applies it to aggregate us agriculture issues addressed include tests of standard hypotheses about the underlying technology homotheticity neutral technical change etc as well as examination of consistency in aggregation and the effects of changes in the level of aggregate expenditure on farm output since there already exist several studies empirically describing agricultural production technologies with indirect objective functions one might fairly ask whether this paper really breaks any new ground we feel that it does one reason is that existing studies e g binswanger 1974 lopez 1980 ball and chambers 1982 ray 1982 and weaver 1983 all rely on either profit or cost functions to date there appears to be only one study using an indirect production appelbaum 1979 and it is not in agriculture this seems unfortunate because there are many instances in agriculture for which an indirect productio

dynamic firm behavior and regional deadweight losses from a u s oil import fee this paper analyzes the national and regional efficiency aspects of a 5 per barrel fee on crude oil imported into the united states the emphasis of the paper is twofold firstly a dynamic model of firm behavior capturing explicitly both expectations formation and resource nonrenewability is used to assess the impact of the fee on domestic firm behavior and secondly the regional breakdown of the producer and consumer surplus changes tariff revenues and deadweight losses or gains is performed by taking explicit account of stock ownership in oil producing and oilconsuming corporations and consumption by end use sector the import fee is a politically contentious issue but one that refuses to go away in political circles the perceived benefits of the fee are usually seen as increased energy security and aid to a beleaguered domestic oil and gas industry perceived drawbacks are usually inflation and regional inequities the last point is the political downfall of the tariff producing states are seen to gain from the higher prices brought on by the tariff and consuming states are seen to lose representatives from states with little or no production and this of course covers most states are hard pressed to sell the idea to constituents this paper thus deals with two of the most important questions from a policy perspective the regional incidence of the tariff and its impact on domestic output in a related paper 20 i discuss the economic rationales for an oil import fee i find that any optimal tariff arguments based on u s monopsony power in the world oil market are not valid in today s market estimates show an import supply curve of approximately infinite elasticity and thus an optimal tariff near zero i dispense with the energy security rationale for a tariff as well arguing that any risk of a disruption of imports in the future and that risk may be small in today s market is best handled with other policy tools such as government owned or subsidized stockpiles these conclusions imply that a tariff would impose deadweight losses on the u s economy by encouraging overproduction of domestic petroleum resources and underconsumption of petroleum imports how much overproduction results from the tariff is the focus of section ii below a
