transfers and the generalized theory of distortions and welfare recent theoretical attention devoted to the transfer paradox has included attempts to incorporate it into the body of commercial policy in this paper the existence of a family of always feasible corrective tax policies is proved which guarantees normal welfare response the set of pol icies is shown to contain the external trade fixing tariff and the op timal tariff the set of policies is then extended to include a capit al flow fixing profits tax to deal with the problems of foreign inves tment the results are then interpreted in terms of a general proposi tion in the theory of distortions and welfare copyright 1987 by the review of economic studies limited

fishing effort its testing specification and internal structure in fisheries economics and management abstract the concept of fishing effort is central to fisheries economics and management however effort is an aggregate index of inputs which can be consistently formed only under the condition on production technology of homothetic separability of inputs this paper develops the conditions under which effort can be consistently formed it then provides the first empirical test for effort and jointness in inputs in a fishery by estimating a multiproduct function for the new england otter trawl fleet after not rejecting input output separability and rejecting nonjointness in inputs the construction of a superlative index for effort is demonstrated through estimating a translog production function the implications of effort s internal structure for fisheries management are then considered

interfuel substitution biomass consumption economic growth and sustainable development evidence from brazil abstract this paper examines the possibilities of substituting the fossil fuels including natural gas coal and oil for biomass consumption in brazil for the period 1980 2015 we used the ridge regression procedure to generate the parameter estimates from a second order taylor series approximation of log linear trans log specification for robustness sake we constructed an index of sustainable development sd as additional regressand alongside the conventional gross domestic product gdp overall the results show strong evidence of substitution possibilities between biomass and the fossil fuels in both the gdp and the sd models indicating that brazil can continue with its growth and sustainability agenda by using more biomass and less fossil fuels the results also show that the sd model gives a more robust output elasticity estimates as it detects the inherent negative effect of some of the fossil fuels on the economy that are not directly observable in the gdp model

foreign investment and economic growth characterization of a second best policy for welfare gains abstract this paper prescribes corrective taxes for immiserizing growth and customs union formation growth through removal of trade barriers when the home country and the rest of the world are financially linked through foreign investment and ownership of assets an always feasible policy which generates pareto welfare gains for home country residents and union countries residents is found with foreign ownership the policy generally requires a specific profits tax in addition to the usual taxes on traded goods and factors the policy does not harm residents in the rest of the world growth is pareto non inferior from the world point of view

foreign ownership and the theory of trade and welfare some standard topics in the theory of international trade are reconsidered in this paper by distinguishing between national and aggregate income when fixed supplies of foreign inputs are present within the home country under conditions that would ensure a national welfare gain if foreign ownership were absent international transfer economic growth or tariff policy might cause a national welfare loss in the presence of foreign ownership the techniques developed could be applied to other domestic distinctions such as those based on race sex age or ethnicity and to the theory of customs unions in a three country world

is a uniform social policy better fiscal federalism and factor mobility this paper develops a two country model to study two questions how do the degrees of centralization of redistribution and of factor mobility affect the productive efficiency of the economies what degrees of centralization of redistribution and of factor mobility are likely to be chosen by majority rule the model shows that a system of centralized redistribution can lead to less efficient outcomes if labor or capital are not mobile and an inefficient outcome with incomplete or no factor mobility receives a majority of votes in both countries whenever the structure of labor markets is very different in the two countries

estimates of inter fuel substitution possibilities in chinese chemical industry abstract the chemical sector is a key driver of china s remarkable growth record and accounts for about 10 of the country s gdp this has made the industry energy intensive and consequently a major contributor to greenhouse gas emissions ghg and other pollutants this study has attempted to investigate the potential for inter fuel substitution between coal oil natural gas and electricity in chinese chemical sector by employing a translog production and cost function ridge regression procedure was adopted to estimate the parameters of the function estimation results show that all energy inputs are substitutes in addition the study produces evidence that the significant role of coal in the chinese chemical fuel mix converges over time albeit slowly these results suggest that price based policies coupled with capital subsidy programs can be adopted to redirect technology use towards cleaner energy sources like electricity and natural gas hence retaining the ability to fuel the chemical sector while also mitigating ghg emissions notwithstanding one must understand that the extent to which substituting electricity for coal will be effective depends on the extent to which coal or oil is used in generating electricity the findings of this study provide general insights and underscore the importance of chinese government policies that focus on installed capacity of renewable electricity energy intensity targets as well as merger of enterprises

inter factor inter fuel substitution carbon intensity and energy related co2 reduction empirical evidence from china carbon dioxide co2 reduction which is the central issue in addressing global warming depends on the extent that clean energy can substitute for co2 emitting coal and non energy factors can substitute for energy factor the purposes of this paper are to empirically investigate inter factor inter fuel substitution in china and to evaluate the determinants of china s energy related carbon intensity as well as mitigation effects of carbon tax considering china s rapid increase in energy consumption and the slow adjustment in substitution the two stage estimation method and the dynamic error correction mechanism are employed in this study the empirical results suggest substitutability among different types of energy sources as well as substitutability among energy labor and capital the magnitude of cross price elasticities indicates that the substitutions are inelastic which limits the scope of the chinese government to implement substitution strategy aiming at energy conservation and environmental management china s carbon intensity declined during 1985 2012 most of which can be attributed to labor substitution and energy price increase however carbon intensive technology being embodied in china s capital investment energy consuming equipment has contributed to the increase in carbon intensity a carbon tax of rmb 50 tonne could reduce 332 9 million tonnes co2 emissions on the basis of 2012 in addition if ignoring the feedback between inter factor inter fuel substitutions co2 mitigation potential would be underestimated

industrial energy substitution during the 1980s in the greek economy abstract factor substitution in greek manufacturing during the 1980s is examined using pooled data in static and dynamic translog expenditure share models inputs are capital labor electricity and non electrical energy liquid solid gas own price elasticities for capital and labor are inelastic but for electricity more elastic 0 90 results indicate substitutability among factors in the short run in the long run electricity and capital are complements as are labor and non electrical energy greek manufacturing is predicted to continue decreased consumption of liquid fuels to the year 2000 continuing the electrification begun in the 1970s

the determinants of aggregate energy use in west germany factor substitution technological change and trade this paper examines the determinants of production related energy use in west germany over the period 1976 1994 the approach is to estimate a system of share equations for energy capital low skilled labor high skilled labor and materials in the west german production sector taking account of biased technological change and increasing trade orientation while technological change is found to be energy saving increased openness is energy using i e tends to increase the energy share factor substitution biased technological change and trade contribute to the year to year volatility of energy intensity in the proportion 66 30 4 the results are robust across several specifications examined

economic growth and interfactor interfuel substitution in korea this paper investigates the impact of increases in oil consumption and changes in wage rates on the interfactor interfuel substitution in korea a two stage translog cost function is estimated to incorporate the feedback effect between the interfactor and interfuel substitution empirical results show that the substitutability complementarity relationships among factors and fuels exhibit substantially different patterns before and after 1989

the energy rebound effect in china s light industry a translog cost function approach abstract china is in its industrialization and urbanization development stage which requires strong energy support with the largest population in the world the energy endowment of china is relatively small therefore energy conservation is one of the key tools for china s sustainable development and energy security when making policies for conservation the chinese government needs to deal with rebound effect carefully in 2012 china s light industry consumed 316 million tons of coal equivalents accounting for 9 percent of the country s total energy consumption which is about the total amount of energy consumed by south korea based on the translog cost function the magnitude of rebound effect in china s light industry is estimated for the first time using the dynamic ordinary least squares and seemingly unrelated regression methods considering the asymmetric effects of energy prices on energy consumption the rebound effect is approximately 37 7 and all the inputs are substitutes except for labor and energy the different magnitude of rebound effect between light and heavy industry is discussed and some policy implications are provided for more effective energy conservation allowing for the rebound effect

prices versus quantities in fisheries models this paper discusses the conditions for generalizing the analysis in weitzman 1974 to fisheries it is shown that it is straightforward to generalize the analysis if the cost function is direct additively separable in stock size and catches this leads to the conclusion that the analysis holds for a schooling fishery with and without search costs but it might not hold for a search fishery a further result is that for a schooling fishery without search costs where the marginal cost function is steeper than the marginal benefit function taxes are likely to be preferred over individual transferable quotas

china s energy economy technical change factor demand and interfactor interfuel substitution with its rapid economic growth china s primary energy consumption has exceeded domestic energy production since 1994 leading to a substantial expansion in energy imports particularly of oil china s energy demand has an increasingly significant impact on global energy markets in this paper allen partial elasticities of factor and energy substitution and price elasticities of energy demand are calculated for china using a two stage translog cost function approach the results suggest that energy is substitutable with both capital and labor coal is significantly substitutable with electricity and complementary with diesel while gasoline and electricity are substitutable with diesel china s energy intensity is increasing during the study period 1995 2004 and the major driver appears to be due to the increased use of energyintensive technology

does the welfare state affect individual attitudes toward immigrants evidence across countries abstract this paper analyzes welfare state determinants of individual attitudes toward immigrants within and across countries and their interaction with labor market drivers of preferences we consider two mechanisms through which a redistributive welfare system might adjust as a result of immigration under the first model immigration has a larger impact on high income individuals while under the second one low income individuals are those most affected individual attitudes are consistent with the first welfare state model and with labor market determinants in countries where immigration is unskilled income is negatively correlated with pro immigration preferences while skill is positively correlated with them these relationships are reversed in economies characterized by skilled migration

limited entry licensing insights from a duration model limited entry is used to manage many fisheries effectiveness depends on a program s ability to control aggregate fishing power which fleet size and composition both affect this article analyzes fleet composition and attrition in a limited entry fishery the california red sea urchin fishery it explores the dynamics of heterogeneity in catch and revenue and applies duration analysis to study individual fisherman attrition using both individual level and time varying covariates the results show that the fleet is becoming more homogenous but also more potent and spatially mobile regulations such as size limits and season restrictions tend to increase attrition

international migration and the role of institutions we study the determinants of international migration with special attention to the role of institutional factors other than economic and demographic fundamentals we evaluate the impact of political institutions and of those institutions specifically targeted at attracting migrants for a dataset on 19th century migration we find that economic and demographic differentials play a major role but that the quality of institutions also matter we produce evidence that both political and migration institutions represent significant factors of attraction even after controlling for their potential endogeneity through a set of instruments exploiting colonial history and the institutions inherited from the past

customs unions and the core abstract customs union formation is modeled as a two stage game in the first stage countries make coalitional choices according to core theory in the second stage optimal tariffs are determined this yields a theory that predicts which customs unions form an example shows that a customs union can be an equilibrium even when both member countries do better at free trade

an empirical analysis of production distortions in the mid atlantic surf clam and ocean quahog fishery this paper presents empirical evidence of production distortions under controlled access management in the mid atlantic surf clam and ocean quahog fishery results indicate that vessels harvested multiple clam species even though the harvest technology exhibits diseconomies of scope vessels also operated in a region of the production surface where the marginal product of vessel capital services was negative these distortions are explained by perverse regulations which restricted vessel capital replacement and severely limited fishing times

rent seeking and incentives for compliance in the commons this article studies how rent seeking behavior induces an informal leasing market for fishing licenses that leads harvesters in a common pool to circumvent rules set by the manager to conserve the resource as well as how the vulnerability of the resource to such behavior depends on the management approach adopted license leasing reduces fleet heterogeneity in terms of catch per unit effort as demonstrated by the outward shift in the stochastic production frontier while aggregate harvest is invariant to alternative profiles of fleet heterogeneity in quota managed fisheries the productivity of the restricted variable total effort increases with the number of leasing contracts in input controlled fisheries if unanticipated by the regulator the additional pressure on the resource may lead to overfishing and compromise the long term viability of the industry

output supply and input demand system of commercial and backyard poultry producers in indonesia indonesia s domestic broiler production has grown rapidly in part because of a ban on imports of poultry parts and strict inspection and meat certification requirements whether indonesia will continue to protect the domestic broiler sector and import feed grains and other inputs or whether it will directly import meat products is a relevant question to many stakeholders this study uses a normalized quadratic function to estimate the output supply of commercial and backyard broiler producers in indonesia and the input demand for three major inputs day old chicks feed and labor data come from three datasets a 1996 household survey and 1996 and 2000 surveys of commercial producers for the most recent dataset the own price elasticity in both the output supply and feed input demand equations were found to be significant the signs of the elasticities were theoretically consistent with a positive supply and negative demand elasticity the magnitudes of the elasticities were smaller than expected the supply elasticity was 0 285 the inelastic supply explains the high border protection imposed by indonesia which in turn implies that any income driven expansion in the quantity of broiler product demanded would be quickly constrained by rising prices consequently supply from imports would become attractive and would dampen any incentive for growth in the domestic sector this result cast doubt on the long term sustainability of indonesia s import substitution policy regime

the breakup of nations a political economy analysis this paper develops a model of the breakup or unification of nations in each nation the decision to separate is taken by majority voting a basic trade off between the efficiency gains of unification and the costs in terms of loss of control on political decisions is highlighted the model emphasizes political conflicts over redistribution policies the main results of the paper are i when income distributions vary across regions and the efficiency gains from unification are small separation occurs in equilibrium and ii when all factors of production are perfectly mobile all incentives for separation disappear i introduction following the demise of communism the entire map of europe from the atlantic coast to the urals is being redrawn and issues of separation unification and the redrawing of borders are yet again at the forefront of european concerns many of the issues raised by this process are primarily of a political cultural or linguistic nature however there are also economic considerations that bear on this problem the objective of this paper is to analyze some important economic and political determinants of the process of unification and separation of democratic nations the starting point of our analysis is to suppose that from an economic efficiency point of view separation of nations is never desirable a unified nation is always more efficient since free trade among regions is guaranteed duplication costs in defense and law enforcement are avoided and local public goods provision such as transportation and communication networks or common standards can be coordinated furthermore any benefits of decentralization that might be obtained in a world with several nations may also be achieved within a unified nation by replicating the administrative structure of the world with several

a thorn in the lion s paw has britain paid too much for common market membership the welfare consequence of britain s entry into the common market is studied for 1972 1980 the figures show that in some years britain would have been better off by 3 4 percent of gdp trading on its own its average losses were greater than 1 5 percent of gdp moreover a feasible alternative arrangement is described in which common market association would benefit both great britain and other common market countries without harming non common market countries the methodology involves a general equilibrium model of customs union formation which determines financial arrangements such as cross country compensation and the distribution of common tariff revenues obviously similar studies can be done for other applications such as the proposed north atlantic free trade area

stock size harvesting costs and the potential for extinction the case of sealing starting in the 1960s considerable opposition to the canadian and norwegian harp seal hunt off newfoundland developed it was alleged that the seal hunt was unethical and that the seal population had been seriously depleted the purpose of this paper is to analyze the production function for the seal hunt based on data for the norwegian seal hunt particular attention is paid to the question whether free entry to the fishery will cause overexploitation this depends critically on the characteristics of the production function in particular the extent to which harvesting costs depend on stock size

impacts of technological change on factor substitution between energy and other inputs within us agriculture 1950 79 abstract past efforts to estimate elasticities of substitution between inputs both in and out of agriculture have usually made use of a single data set to provide the elasticities between the input pairs and have led to highly conflicting results particularly with respect to the substitution between capital or machinery and energy this study reveals that the elasticity of substitution between a number of input pairs in agriculture can vary by substantial amounts depending on the time period used for the estimation energy in agriculture which was a complement for machinery in the 1950s was a substitute by the 1970s

on the political economy of immigration the authors study how immigration policies that impose capital and skill requirements would be determined under majority voting when native agents differ in their wealth holdings and vote to maximize their income the results of the model calculations indicate that the native population will be polarized between those who would like an immigration policy to maximize the domestic capital labor ratio and those who would like an immigration policy that would minimize it

long run profit functions for multiproduct firms a long run specification of the multiproduct profit function is developed from the restricted profit function the multiproduct restricted profit function and the envelope condition are used to estimate the optimal long run levels of the quasi fixed factor formulas for long run marshallian elasticities of substitution and transformation economies of scope product specific and overall economies of scale and economic measures of capacity utilization are developed for the translog functional form the methodology is illustrated by a case study of the new england otter trawl industry

transferable quotas enforcement costs and typical firms an empirical application to the norwegian trawler fleet an alternative to traditional regulations of fisheries to avoid rent dissipation is the use of individual transferable quotas itqs where prices in the quota market provide the necessary information to owners of harvest rights to contract with each other however even under such a decentralized regime information on the underlying technology of the fishing vessels is also necessary first since most fisheries consist of many interrelated production processes in order to avoid rent dissipation by discarding wrong output mix etc the structure of production in the multispecies fishery must be known to design a proper quota system second an itq system may create incentives for misreporting by understating the actual catch this may especially be the case where the expected degree of self enforcement is low the paper proposes a way to reduce the information requirements under regulation with asymmetric information by constructing a typical firm and comparing performance for the other vessels to this firm based on the typical firm and if the industry is relatively homogenous the performance and hence catch of any other firm in the industry can be predicted within a certain range further the paper applies this idea to the norwegian trawler fleet to assess the production structure in terms of jointness input output separability and the supply and demand elasticities for the fishing firms this information characterizes the fishery and thus how the quota system may be designed and how to construct a yardstick in order to reduce the enforcement cost under a decentralized regulation of itqs

is unilateral tariff reduction preferable to a customs union the curious case of the missing foreign tariffs during the past decade and a half an important part of the literature on customs unions has dealt with the question of whether a country might obtain the gains it would achieve from a customs union cu in an alternative way by a unilateral tariff reduction utr utr may involve a partial reduction in tariffs or a reduction all the way to zero a widely accepted conclusion see eitan berglas p 329 c a cooper and b f massell 1965b pp 745 47 roma dauphin ch 2 harry johnson p 280 melvyn krauss pp 417 19 and peter robson is that utr does indeed hold out the prospect for all the gains from a cuwithout the disadvantagesif two important simplifying assumptions are made namely that we ignore economies of scale and the effects of a customs union on the terms of trade 2 in the words of berglas it is important to note that if a preferential trade agreement does not affect the terms of trade then it does not allow for any mutually beneficial policy opportunities which are not open to each of the member countries separately through utr p 329 if this conclusion is correct it is very important in that it undercuts the earlier literature on customs unions the question asked by jacob viner in his pioneering work whether a cu represents a net gain or a net loss in economic efficiencybecomes unimportant except insofar as a customs union is based on terms of trade effects3 or economies of scale 4 since a cu can be summarily rejected in favor of utr the utr case would mean that for economists the puzzle is not to identify the efficiency gains or losses from a cu but rather to explain why countries form customs unions in the first place berglas p 329 cooper and massell 1965b p 247 and johnson p 270 indeed in his survey of cu theory krauss identifies the problem raised by cooper and massellof why countries form customs unionsas the theoretical issue of the past decade the 1960 s just as in the prior one the major issue as explicitly defined by jacob viner 1950 was whether a customs union represented a movement towards freer trade or greater protection p 413 the typical reply to the cooper massell question is countries tend to form a cu for noneconomic reasons berglas pp 329 30 5

testing for input substitution in a regulated fishery input restrictions are commonly used to prevent rent dissipation in fisheries this paper examines whether these schemes are successful by calculating the degree of input substitution between restricted and unrestricted inputs conventional elasticities of substitution cannot be used when the firm faces controls on the use of some inputs in this case the appropriate measure of substitution the elasticity of intensity must be used data from the british columbia salmon fishery provide evidence of input substitution possibilities for two vessel types these results call into question the usefulness of input control schemes

who is against a common market this paper develops a theory of the endogenous formation of a common market in a three country two factor political economy model in the status quo home and foreign implement nondiscriminatory policies toward international factor flows in order to maximize the domestic median voter s welfare then the two countries simultaneously hold referenda on a common market initiative leading to the removal of the pre existing policies for factor flows between the member countries while no coordination is imposed on policies vis a vis the rest of the world several interesting results emerge in a common market the returns on factors moving between the members are more likely to increase the larger is the import demand of one country relative to the factor supply of the exporting partner factors that do not relocate are more likely to see their returns decrease when flows are large and import demands are inelastic importantly for the common market to emerge as an equilibrium some factors must continue to experience enhanced protection when the integration process is completed this result highlights the potential tension between social desirability and the political feasibility of the integration process jel f1 f2 p16

multi output nonfrontier primal measures of capacity and capacity utilization this article implements an econometric approach for generating primal capacity output and utilization measures for fisheries in situations where regulatory environmental and resource conditions affect catch levels but are not independently identified in the data frontier based capacity models may interpret such impacts as production inefficiency however if such inefficiencies are unlikely to be eliminated the implied potential output increases may be unrealistic we develop a multi output multi input stochastic transformation function framework that permits various assumptions about how output composition may change when operating at full capacity we apply our model to catcher processor vessels in the alaskan pollock fishery

capital stock labor energy substitution and production efficiency study for china abstract this study estimates the elasticities of substitution for china from 1953 to 2006 by the two level constant elasticity of substitution ces production function with three factor inputs capital stock labor and energy a technological change rate and non constant returns to scale are under considered all possible combinations and two other subdivided periods are carried out respectively and their technological change rates elasticities of substitution and returns to scale are found this study also provides an analysis of production efficiency by using marginal productivity of specific factor input according to the estimated results and distinguishes the marginal productivities deriving from the three different combinations it suggests that the decision makers of china need to consider the effects of different factor inputs on gdp growth

migration and pension with international capital mobility abstract being relatively low earners migrants are net beneficiaries of the welfare state therefore in a static set up migration may be resisted by the entire native born population however it is shown that in a dynamic set up with a pension system which is an important pillar of any welfare state migration is beneficial to all income high and low and all age old and young groups

energy conservation in china s light industry sector evidence from inter factor and inter fuel substitution following the impressive economic achievements in the past decades china is faced with energy and environmental challenges to carry out more effective and targeted energy policies the heterogeneities of different industrial sectors are of great importance the energy consumption of china s light industry in 2012 was 316 million tons of coal equivalents which is about the energy consumption of south korea the paper explored the substitution relationships between various input factors and fuel sources and showed that electricity price reform is crucial for energy conservation in china s light industry then the dynamics of energy intensity change is examined by decomposing energy intensity into budget effect substitution effect output effect and technology advance effect the result revealed that the substitution effect between input factors is a key driving force however technology progress seems to contribute very little for future energy policy alternatives promoting the implementation of new conservation technology and electricity price reform may be effective measures

public regulation and the structure of production in multiproduct industries an application to the new england otter trawl industry this article considers the problem of managing multispecies fishing industries as one of regulating the production of individual multiproduct firms the multispecies new england otter trawl industry is examined within this framework empirical results derived from estimating a multiproduct profitfunction indicate that management consistent with the structures ofmultiproduct production and costs would directly regulate inputs little support is provided for applying the traditional bioeconomic model to the fishery studied

dynamic translog and linear logit models a factor demand analysis of interfuel substitution in us industrial energy demand abstract we compare and contrast two popular dynamic flexible functional forms for cost functions the translog and the logit j bus econ stat 8 1990 347 353 using data on us industrial energy demand from 1960 to 1992 which has been analysed by previous studies energy econ 11 1989 89 94 appl econ 21 1989 931 945 j bus econ stat 13 1995 459 465 we show the crucial role played by different dynamic formulations of the translog in this analysis of factor demands with respect to rates of dynamic adjustment and substitution possibilities we conclude that the poor performance of the dynamic translog relative to the dynamic logit cannot be explained solely by dynamic model mis specification or the inclusion of price unresponsive non energy fuel use data our most robust empirical result is that coal and oil are substitutes

an analysis of the efficient production frontier in the fishery implications for enhanced fisheries management the transformation relationship between factor inputs and outputs the efficient production frontier epf contains important information for fisheries managers a directional technology distance function model of the harvesting technology is used to measure changes in the epf over time frontier shifts are summarized with input and output based frontier indicators that are interpreted as measures of bioeconomic productivity change the model is applied to the mid atlantic surf clam and ocean quahog fishery

fishing effort validation and substitution possibilities among components the case study of the viii division european anchovy fishery command and control regulation programmes particularly input constraints typically fail to achieve stated objectives because fishermen may substitute unregulated for regulated inputs it is thus essential to have an understanding of the internal structure of production technology a primal formulation is used to estimate a translog production function at the vessels level that includes fishing effort and fisherman s skill the flexibility of the selected functional permits the analysis of the substitution possibilities among inputs by estimating the elasticity of substitution with no prior constraints particular attention is paid to the empirical validation of fishing effort as an aggregate input which implies either the acceptance of the joint hypothesis that inputs making up effort are weakly separable from the inputs out of the subgroup or considering that effort is an intermediate input produced by a non separable two stage technology cross sectional data from the spanish purse seine fleet op

capital energy substitution evidence from a panel of irish manufacturing firms abstract we use a translog cost function to model production in the irish manufacturing sector over the period from 1991 to 2009 we estimate both own and cross price elasticities and morishima elasticities of substitution between capital labour materials and energy we find that capital and energy are substitutes in the production process across all firms we find that a 1 rise in the price of energy is associated with an increase of 0 04 in the demand for capital the morishima elasticities which reflect the technological substitution potential indicate that a 1 increase in the price of energy causes the capital energy input ratio to increase by 1 5 the demand for capital in energy intensive firms is more responsive to increases in energy prices while it is less responsive in foreign owned firms we also observe a sharp decline in firms responsiveness in the first half of the sample period

an extension of the kemp wan theorem on the formation of customs unions abstract kemp and wan 1976 proved that nations forming a customs union can always compensate each other so that no nation will be worse off relative to the pre union equilibrium their proof however is existential giving no clue how to construct such compensation schemes this paper proposes a particular compensation scheme which is always feasible further there are circumstances where this scheme is the only feasible one at world prices the arrangement breaks even for each nation at post union internal prices member compensations sum to the union s tariff receipts the proof that such a scheme is feasible depends upon the grandmont mcfadden theorem

resource rent in individual quota fisheries traditional fisheries management schemes generate incentives for vessels to maximize catch resulting in rent dissipation and overcapacity individual vessel quota management schemes change the incentives to maximize profit and have the potential to generate resource rent and reduce capacity an interesting question is whether it is the changed incentives due to individual quota or the capacity reduction due to transferability of individual quota that is most important in generating rent in this study a cost function approach is used to model and measure rent generated and potential rent in a fishery managed with individual vessel quotas

cost structure and capacity in the norwegian pelagic fisheries the parameters of the short run cost function are estimated for three vessel types taking part in the norwegian pelagic fisheries purse seine vessels trawlers and coastal vessels the generalized translog functional form is used estimates of returns to scale are calculated and the results indicate that there are substantial economies of scale in all vessel classes it is further investigated whether excess capacity varies with vessel size and age the analysis suggests increased quotas per vessel to avoid rent dissipation with the total allowable catch given the number of participating vessels must be reduced

asymmetric substitutability between energy and capital evidence from the manufacturing sectors in 10 oecd countries abstract this paper investigates the substitutability between energy and capital in the manufacturing sectors of ten oecd countries since 1980 by applying a cost function approach that has been widely used to analyze industrial energy demand first we attempt to determine the source of the disagreement in the literature on the substitutability between energy and capital and reach a conclusion regarding the substitutability between energy and capital dividing energy and capital into sub inputs we analyze their substitutability the empirical results indicate that fuel tends to complement capital in most countries whereas electricity and capital are substitutes thus this study confirms that heterogeneity in energy sources is a primary component of the systematic variation in the substitutability between energy and capital second we examine asymmetric substitutability between energy and capital by estimating the morishima elasticity of substitution the estimates of the morishima elasticity of substitution demonstrate that the substitution of energy for capital has dominated the substitution of capital for energy this asymmetric substitutability is natural from the producer perspective because capital costs are much greater than energy costs in most countries these results imply that the adoption of energy saving technologies has not been induced in response to increased energy prices

the lay system in commercial fisheries origin and implications abstract in most commercial fisheries the crew is remunerated via some form of the lay system under the lay system the crew is paid with a share of revenues or a share of revenues less costs naturally the presence and the functioning of the lay system are well known and accepted as one of fishery s important institutions compared with share contracts in agriculture however the lay in fisheries has garnered relatively little research this article has two goals first we provide an explanation for the existence of the lay system as an incentive mechanism to alleviate a potential team agency problem this explanation of the lay system explains anomalies such as the presence of wages in some fisheries that are odds with the theory of pure risk sharing second we show the implications of the lay system for econometric modeling of fisheries and for understanding firm behavior in general we conclude that models that fail to account explicitly for the incentive properties of shares are likely to provide poor representations of fishing firm behavior the thrust of the paper is that the formation and working of the lay system are a fundamental force in fisheries influencing firm behavior and research results in a way that has been largely ignored

technical efficiency effects of input controls evidence from australia s banana prawn fishery this paper provides the first ex post estimates of the effects of input controls on technical efficiency in a fishery using individual vessel data from the northern prawn fishery of australia for the years 1990 1996 and 1994 2000 stochastic production frontiers are estimated to analyse the efficiency impacts of input controls on engine and vessel size the results indicate that technical efficiency is increasing in a measure of vessel size and engine capacity that was controlled by the regulator from 1985 to 2001 and decreasing in an unregulated input gear headrope length the study shows that fishers have substituted from regulated to unregulated inputs over the period 1990 2000 and technical efficiency has declined coincident with increasing restrictions on vessel size and engine capacity the decline in technical efficiency indicates that the goal of the regulator to increase economic efficiency has not been realized

explaining non compliance in the norwegian coastal cod fishery an application of the multinomial logit establishing motive is central to the analysis of criminal behaviour this article analyses the range of motives for noncompliant behaviour among coastal cod fishermen a multinomial logit model is employed to analyse the reasons that underlie various motives the four motives compared in this study are economic technological and social and motives caused by bureaucracy and legitimacy problems the economic motive is found to be most important for coastal fishermen however the cross sectional data indicate that motives vary with fishing gear vessel length and fishermen s age the results indicate that identifying motives for noncompliant behaviour is not straightforward but is important for reducing the extent of infringements of the regulations fishermen who use gill net seine and long line for example are more often motivated to noncompliance by technical problems and bureaucracy than hand jig fishers the study suggests that in order to prevent noncompliance behaviour the authorities manageme

towards a common market factor mobility in a customs union this paper examines whether the member countries of a customs union would gain from moving towards the next stage of economi c integration the common market when the set of common external tar iffs is not chosen optimally increased factor mobility may reduce th e welfare of the customs union however common market formation is t he best policy when a customs union of any size sets its tariffs to t he appropriate levels

output elasticities and inter factor substitution empirical evidence from the transportation sector of shanghai abstract as a major consumer of fossil fuels the transportation sector in shanghai presents a wide range of problems including air pollution noise and traffic congestion this study aims to explore the energy substitution effect based on a trans log production function to evaluate the contribution of each input factor to sectoral output and reveal the substitution possibilities between capital labor and energy to deal with a multicollinearity problem we adopt ridge regression to obtain the coefficient of each variable under the appropriate penalty value the bootstrap method is used for making statistical inferences and the 95 confidence interval is obtained with 1000 bootstrap samples the empirical results demonstrate the following 1 the output elasticities of capital 0 13 0 15 labor 0 24 0 25 and energy 0 43 0 48 are positive and show an increasing trend over the study period 2 the substitution elasticity between labor and energy is the highest among the input factors around 1 0095 with a slight decreasing trend 3 the substitution elasticity between energy and capital ranges from 1 0018 to 1 0021 and the substitution elasticity between capital and labor is infinitely close to 1

trade as transfers gatt and the core abstract we show in our model of international monopoly trade that transfers proposed by grinols grinols e l 1981 an extension of the kemp wan theorem on the formation of customs unions journal of international economics 11 259 266 support the grand coalition as a core allocation we compare these transfers to those supporting the shapley value

factor and fuel substitution in china s iron steel industry evidence and policy implications climate change which is induced from energy consumption and co2 emissions has got people s attention hence many strategies and ways are being adopted to mitigate co2 emissions energy substitution is crucial to the promotion of energy conservation and co2 emissions reduction the purpose of this paper is to estimate both inter factor and inter fuel substitution in china s iron steel industry during the period 1985 2011 empirical results show several conclusions for china s iron steel industry 1 own price elasticity of energy is negative so increase in energy price will reduce energy input 2 energy and capital and energy and labor are substitutes and the substitution in energy capital is relatively stronger 3 though coal oil and electricity are also substitutes the substitution effect is not so obvious because of pricing distortions in china the driving forces of energy efficiency change are further discussed and the results show that technology progress is the key factor determining energy intensity therefore market oriented reforms in terms of energy prices improvement in energy substitution including inter factor and inter fuel substation and promotion of energy saving technologies are important means for ensuring future energy conservation and co2 emissions reduction practices in china s iron steel sector

does factor market distortion inhibit the green total factor productivity in china abstract this article measures green total factor productivity gtfp to discuss whether factor market distortions inhibit the green development of china s economy meanwhile export and foreign direct investment fdi are taken into account based on a threshold model considering export and fdi are closely related to factor market distortion environment and the economy the result shows that the factor market distortion has negative influences on china s gtfp growth export and fdi s spillover effect significantly moreover factor market distortion was found to be the threshold of export and fdi s spillover effect leading to inferior export and fdi which further inhibit gtfp growth this article provides a supplement to the issue from the perspective of environment based on the widely confirmed proposition that factor market distortion inhibits tfp growth according to the results we suggest that the chinese government should reduce the control of factor market as much as possible leaving the factor resources allocation to the market this will not only promote an innovation driven development but also an energy saving and environment friendly economy in china the article provides a new perspective on the influence mechanism of export and fdi on gtfp growth by discussing the impact path of factor distortion and expands the empirical framework of the research direction as well
