cooperative management of groundwater resources in the presence of environmental externalities this paper investigates how cooperation among users can achieve a better management of groundwater in the presence of environmental externalities cooperation allows users to internalize the damages caused by their activities and reduce extractions the paper develops a game theoretical framework to assess the value of cooperation in an aquifer that is divided into three sub aquifers that are being overly exploited two types of externalities are modeled first water extractions in each sub aquifer impact water levels in neighboring sub aquifers extraction externality second the three sub aquifers are also connected to an ecosystem and thus decisions in each sub aquifer affect the health of the ecosystem environmental externality a cooperative game theory model is applied the model empirically shows how the uncontrolled extractions in each sub aquifer affects neighboring groundwater users but also cause severe impacts to the linked ecosystem the model is tested empirically in one of the most important aquifers in spain the eastern la mancha aquifer the results illustrate how both extraction and environmental externalities interact in affecting the likelihood of cooperation among the users the paper estimates the value of cooperation and its stability with and without the environmental externality

inflation regimes core inflation measures and the relationship between producer and consumer price inflation to date an overwhelming majority of the literature has addressed mean relationships between producer and consumer price inflation granger et al 1986 represent the only attempt to investigate second moment relationships we examine the consumer producer price relationship employing a multivariate garch m framework that allows simultaneous estimation of the bivariate system along with providing explicit times series estimates of the variances of consumer and producer price inflation this research also breaks new ground in the use of core and over all inflation variance measures as well as examining state dependent mean and variance relationships we find that mean relationships are generally sensitive to the measure of inflation used food and energy prices play an important role in transmitting changes in aggregate input prices to aggregate output prices when food and energy prices are eliminated from consumer and producer price inflation measures mean relationships break down irrespective of whe

water markets and freshwater ecosystem services policy reform and implementation in the columbia and murray darling basins abstract water markets have featured prominently in the reallocation of water rights to restore freshwater ecosystem health incentive based water rights acquisition and transactions have emerged as a market oriented policy approach to reallocate water resources from existing uses to enhance the provision regulation and sustainability of freshwater ecosystem services this paper develops a conceptual framework to examine factors enabling and constraining successful policy reform and implementation in market based environmental water allocation this analysis distills and extends the findings and lessons of a september 2007 workshop in brisbane australia on environmental water transactions two case studies were selected in water stressed basins the columbia u s a and murray darling australia basins where transactional approaches to environmental water allocation first emerged the case studies draw upon practitioner perspectives and previous policy and economic analysis in two regions where shared political economic and physical conditions lend a strong analytical basis for comparison a common set of policy and regulatory reforms has occurred in both cases albeit in different forms and via distinct paths to develop three enabling conditions 1 establishment of rights to and limits on freshwater extraction and alteration 2 recognition of the environment as a legitimate water use and 3 authority to transfer existing water rights to an environmental purpose however these elements of policy reform are necessary but not sufficient for effective implementation a second set of driving forces barriers and adaptations explains the ability to achieve larger scale ecological outcomes these conditions include the physical social and economic factors driving demand for environmental water allocation administrative procedures organizational development and institutional capacity to effect transfers and adaptive mechanisms to overcome legal cultural economic and environmental barriers the case study analysis suggests that environmental water transactions can play an important role in establishing environmental water allocations although water markets require ongoing institutional capacity and adaptive governance the conceptual framework and empirical lessons generated through this cross case comparison provide the basis for an expanded research agenda to evaluate the design and performance of market oriented reforms as implementation experience accrues and new programs emerge in diverse ecological and political economic settings

measuring market integration in the presence of transaction costs a threshold vector error correction approach applied econometric analyses of market integration based on price data alone have been criticised because they neglect the role of transaction costs to meet this objection threshold vector error correction models are used threshold models can account for the effects of transaction costs in price transmission without directly relying upon information about these costs which are often unavailable it is argued that threshold models that are based on two thresholds provide results that are economically more intuitive than those obtained from one threshold models however to this point no adequate econometric test is available for threshold significance in a two threshold model such tests are only available for the one threshold model in this paper a restricted two threshold model is developed in which the significance of the thresholds can be tested this model is therefore amenable to economic interpretation and statistical inference the model is used to estimate market integration in the european pig market

recreational demands for maintaining instream flows a contingent valuation approach recreational uses of streams although nonconsumptive increasingly conflict with traditional off stream uses of water in arid regions recreational demands for instream flows have collective good attributes such that the recreationists preferences may be inadequately reflected in water allocation decisions the contingent valuation approach was adapted to impute instream flow shadow prices from a sample of recreationists on the cache la poudre river in northern colorado during periods of relatively low flows the estimated instream flow marginal value exceeds the marginal value of water in irrigation suggesting a need for altered water allocation policies

a private property rights regime to replenish a groundwater aquifer groundwater management is often reactive and in some cases the groundwater stock groundwater table of an aquifer may fall below its optimal steady state level before any thought is given to management this paper examines a private property rights regime to restore a groundwater resource to its optimal steady state results from a stochastic dynamic programming model of madera county california show that the private property rights regime recovers about 95 percent of the potential gain from groundwater management

privatizing the commons an improvement recent years have seen political economists turning to an institutional paradigm wherein the extent to which property rights are defined and enforced is an important determinant of human action furubotn 1972 the institutional or property rights approach has become an important component of explanations of both economic growth and economic inefficiency the institutional environment now holds a prominent place in explanations of differential growth rates among political units and over time 1 the property rights approach has also become commonplace in the analysis of the environmental crisis where the lack of well defined property rights is seen as the cause of environmental problems and movement toward a more complete specification of those rights as the solution even bureaucratic inefficiencies have been analyzed in the context of property rights mckean 1965

a nonlinear approach to us gnp a univariate nonlinear model is estimated for us gnp that on many criteria outperforms standard linear models the estimated model is of the threshold autoregressive type and contains evidence of asymmetric effects of shocks over the business cycle in particular the nonlinear model suggests that the post 1945 us economy is significantly more stable than the pre 1945 us economy

the value of agricultural water rights in agricultural properties in the path of development article i nfo article history this paper estimates the value of water rights in a rapidly urbanizing semi arid area phoenix arizona to do this we use hedonic pricing to explore the impact of water rights on property values in 151 agricultural land transactions that occurred between 2001 and 2005 we test two main hypotheses 1 that the marginal will ingness to pay for water rights is higher in more developed urbanizing areas than in less developed rural areas and 2 that the marginal willingness to pay for water rights in urban areas is increasing in the value of developed land we find that the marginal willingness to pay for water rights is highest among properties in urbanized or urbanizing areas where a significant proportion of the land has already been developed additionally we find that the marginal willingness to pay for agricultural water rights is greatest in cities where developed land is most valuable

natural resource economics and conservation contributions of agricultural economics and agricultural economists research by agricultural economists on natural resources has been distinguished by an interdisciplinary emphasis and a dynamic perspective it has recognized technological and institutional constraints has been oriented toward solving concrete resource management and policy problems and has emphasized empirical and quantitative analysis agricultural economists have introduced methods for evaluating natural resource conservation efforts for predicting adoption of resource conservation technologies and for designing efficient and sustainable resource management policies they have identified ways of improving land management and preventing land degradation proposed reforms of institutions governing water allocation and water quality and introduced policies for balancing environmental and efficiency considerations in the management of pests biodiversity and livestock diseases their research has had substantial impacts on the formulation of resource conservation policies

governing a groundwater commons a strategic and laboratory analysis of western water law we examine strategic behavior in groundwater depletion within the setting of state governance of groundwater resources in the american west solving a dynamic common pool resource model for its optimal solution and its subgame perfect equilibrium provides benchmarks for behavior observed in laboratory experiments three forms of legal rules common pool depletion with a rule of capture to establish ownership absolute ownership doctrine entry restrictions prior appropriation doctrine and stock quotas correlative rights doctrinekre examined in terms of their impact on individual strategic behavior in laboratory experiments

transaction costs and institutional performance in market based environmental water allocation policy reforms in the columbia basin spurred water rights reallocation for ecological recovery transaction costs have caused implementation to lag this paper examines transaction costs and institutional performance in environmental water allocation it evaluates spatial and temporal performance trends in watershed cases along three dimensions of adaptive efficiency water recovery transaction costs and program budgets performance trends demonstrate intrastate variability and volatility over time due to the importance of local institutional capacity which is uneven within states higher levels of water recovery may coincide with moderate to high transaction costs and program budgets particularly during initial implementation efforts this finding reflects investments in multilevel policy reform to strengthen enabling conditions and adapt to unintended consequences jel q25 q58

a private property rights regime for the commons the case for groundwater we compare the social welfare of pumping groundwater under central optimal control to that obtained under a private property rights regime in which firms are granted tradeable permits to the in situ groundwater stock when firms are risk averse both regimes are suboptimal and the matter of which regime yields greater welfare is an empirical one when firms are risk neutral central control dominates the private property rights regime still a stochastic dynamic programming model of madera county california demonstrates that even in this case the private property rights regime is a promising alternative to central control

the problem of instream flows to obtain a surface water right in the arid american west private appropriators have been required to undertake actual physical diversion of the water that requirement largely negates the role of private contacting to preserve or enhance water flows for recreational wildlife and aesthetic purposes in this paper a model is developed and used to examine the courts rationale for denying private claims to instream flows the ways in which such claims can be made amenable to the prior appropriation system are explored the paper is motivated by the failure of public agencies to achieve an approximately optimal solution

asymmetry and rigidity in farm retail price transmission this article demonstrates how retail price transmission asymmetry can arise from intertemporal optimizing behavior among spatially competitive retailers facing concave spatial demand and shows that vigorous competition among retailers may not necessarily result in the larger retail price declines farmers expect during periods of declining farm prices it also shows that when this particular class of retailers incurs repricing costs retail prices can be rigid over a range of upward and downward movements in the farm price this suggests that the rigidity of retail prices during periods of declining farm prices could be due to repricing costs it also suggests that the appropriate econometric model of price transmission is the model of friction where tobit analysis is the proper method of estimation rather than nonreversible functions

the externalities associated with the common property exploitation of groundwater abstract in this paper the rate of groundwater extraction under the common property arrangement is the outcome of a dynamic game played with feedback strategies the analysis clarifies the externalities associated with the common property extraction of groundwater and identifies an risk externality that arises when firms are risk averse identifying the various externalities bears on the development of appropriate forms of groundwater management in particular the risk externality would be unknown to the watermaster of a central control agency suggesting the need for creative decentralized forms of groundwater management

good bye lenin or not the effect of communism on people s preferences preferences for redistribution as well as the generosities of welfare states differ significantly across countries in this paper we test whether there exists a feedback process of the economic regime on individual preferences we exploit the experiment of german separation and reunification to establish exogeneity of the economic system from 1945 to 1990 east germans lived under a communist regime with heavy state intervention and extensive redistribution we find that after german reunification east germans are more in favor of redistribution and state intervention than west germans even after controlling for economic incentives this effect is especially strong for older cohorts who lived under communism for a longer time period we further find that east germans preferences converge towards those of west germans we calculate that it will take one to two generations for preferences to converge completely

sharing a groundwater resource in a context of regime shifts we study the occurrence of shocks in a common groundwater resource problem using a differential game in particular we use rubio and casino s adaptation of the gisser and sanchez model where we introduce a sudden change in the dynamics of the resource namely a decrease in the recharge rate of the aquifer we compare the pareto optimal solution with open loop and feedback equilibria first we show analytically how different solutions at the steady state depend on the intensity of the shock moreover we show that the cost and the strategic effects are decreasing functions of the intensity of the shock i e that all the solutions get closer at the steady state for more intense shocks we finally apply the game to the particular case of the western la mancha aquifer the aim of this application is to estimate how shocks influence the inefficiency of open loop and feedback strategies in terms of welfare we show that this inefficiency decreases the earlier the shock occurs or the higher the intensity of the shock

resource rights and markets in a general equilibrium model of production rights to a free resource lead to distributional deadweight losses in partial equilibrium the present paper examines related distortions in a general equilibrium model of production with output prices constant for the small open economy the free resource can result in lower output than a market with weak substitution in the other sector the free resource also leads to a convex production frontier implying a price increase lowers output in the sector regarding policy an import tariff export subsidy or price support would lower sector output these general equilibrium distortions increase the incentives to favor resource markets over rights

individual preferences for political redistribution what drives people s support of governmental reduction of income inequality we employ data from a large international survey in order to evaluate the explanatory power of three competing forces referred to as the homo oeconomicus effect the public values effect and the social rivalry effect the empirical analysis reveals that at the aggregate level all three effects play a significant role in shaping individual preferences for political redistribution attitudes of citizens in formerly socialist countries turn out to differ from those of western citizens in a systematic way 2002 elsevier science b v all rights reserved

an empirical study of the asymmetric cointegration relationships among the chinese stock markets the enders and siklos asymmetric cointegration test is employed to examine the long run asymmetric equilibrium relationships between the chinese shanghai and shenzhen stock markets three samples are adopted which are the whole sample october 1992 to september 2002 the first subsample before b shares were opened up to the chinese public october 1992 to february 2001 and the second subsample after b shares were opened up february 2001 to september 2002 the estimated results are as follows first when the conventional engle granger symmetric cointegration test is used only the a shares in shanghai and shenghen stock exchange market are cointegrated when using the whole sample and the first subsample however with the enders siklos m tar asymmetric cointegration test shenzhen a and b shares stock prices have an asymmetric cointegration relationship after b shares were open suggesting that openness increases the market efficiency furthermore the two a shares in shanghai and shenzhen stock exc

non cooperative institutions for sustainable common pool resource management application to groundwater as demands for limited natural resources increase developing management institutions that ensure the sustainability of such resources is essential many natural resources are common pool resources cprs managed under different non cooperative cooperative and externally imposed management frameworks while early studies of non cooperative cpr management suggest inevitable tragedy of the commons here we discuss how users can avoid tragic outcomes by changing their decision making rationales and exploitation strategies even in a non cooperative environment this paper introduces and compares various types of non cooperative institutions that are available to manage cprs these management institutions are then applied using a numerical groundwater exploitation example to determine how different planning variables are affected by the choice of management institution results indicate that cpr users can improve their gains by considering the externalities and developing long term exploitation plans as opposed to short term plans with no consideration of externalities that result in rapid exhaustion of the resource and lead to the so called tragedy of the commons

using tradable water permits in irrigated agriculture the present paper examines both theoretically and empirically the environmental and economic benefits of introducing a policy to optimally manage groundwater used in irrigated agriculture and the efficiency potential of allowing trading of water permits we confirm the results appearing separately in the literature on optimal resource management and tradable permits that both tradable water permits and non tradable quotas provide the basic mechanism for sustainable water use and yield substantial economic benefits and that allowing trading of water permits improves efficiency in order to derive the above results we develop a discrete time model to realistically describe farmer s myopic behavior while using a continuous time model to describe optimal management we also incorporate into the analysis the economic effect of sea water intrusion in the aquifer and we estimate the cost of water overexploitation under myopic behavior the empirical part of the paper is based on simulations using data from an agricultural region in northern greece the main contribution of the paper is the introduction of heterogeneity in crops production and market characteristics we show that the more diverse are the crops in technology and market prices and the stricter is the water constraint the higher are the benefits from using a tradable water permit system

markets for water rights under environmental constraints abstract the cumulative impact of pollutants on water quality at a given location along a river is a function of prior loadings as well as pollution and surface flows at that particular site the question of whether it is possible to maintain water quality under alternative mechanisms for allocating surface water and pollution rights is addressed we model the optimal allocation of surface water and pollution rights along a river with water quality constraints due to cumulative effects the shadow values of water and pollution rights are contingent on location it is shown that a nash equilibrium in a market for tradable surface water rights in conjunction with a market for pollution damages implements the optimal solution the market supports location specific prices for both consumptive water rights and pollution damages

employment determination in enterprises under communism and in transition evidence from central europe the authors present a comparative analysis of employment determination in four transition economies as they moved from central planning to a market economy in the early 1990s they use firm level panel data sets from the czech republic hungary poland and slovakia to estimate dynamic employment equations for the period from immediately before to immediately after the start of transition for the most part firms appear to have been quick to adjust employment to wage levels and there is little evidence of labor hoarding there were important cross country variations in the determinants of employment during the reform process however hungarian and polish firms started the transition already substantially reformed and became even more responsive to market signals as transition proceeded in contrast firms in the czech and slovak republics started in the completely unresponsive mode characteristic of central planning but rapidly caught up with their counterparts in hungary and poland

does asymmetry in price transmission exist in the rice market in sri lanka abstractthis study analyses asymmetry in price transmission between wholesale and retail rice markets in sri lanka using the threshold autoregressive model we found that the wholesale and the retail rice markets in sri lanka are integrated with price changes moving from the wholesale to the retail market however the price transmission process is asymmetric in particular price increases at the wholesale market transmit immediately to the retail market while price decreases transmit more slowly parameter stability test and follow up analysis indicated that the price transmission process is asymmetric only during periods of price surges suggesting that the rice market is not efficient during these periods

a variable threshold band approach to measuring market linkages uncertain and changing economic conditions can have substantial effects on price relationships in spatially separated linked markets although numerous studies have analysed price relationships to characterize market linkage structures most assume that the relationships and associated linkages are time invariant this study extends the literature by modelling and estimating time dependent market linkages that are conditional on changes in exogenous factors the methodology is used to investigate price relationships in north carolina nc corn and soya bean markets empirical results indicate that generalized market linkage models provide a better representation of price relationships over time improving the understanding of price discovery dynamics and marketing strategies

nonlinear adjustments in deviations from the law of one price for wholesale hog prices this article applies the band threshold autoregression band tar model to investigate whether the law of one price loop holds in taiwanese wholesale hog markets during the period from may 1987 through december 2003 we find evidence of a nonlinear mean reversion in deviations from the loop for relative hog prices our empirical study confirms the presence of thresholds and provides strong evidence in support of the view that the regional hog markets have been tightly integrated in taiwan and that the wholesale hog market in taiwan is an efficient market economy furthermore the estimated half lives from the nonlinear generalized impulse response analysis are as short as four months

regulation and distrust in a cross section of countries government regulation is strongly negatively correlated with social capital we document this correlation and present a model explaining it in the model distrust creates public demand for regulation while regulation in turn discourages social capital accumulation leading to multiple equilibria a key implication of the model is that individuals in low trust countries want more government intervention even though the government is corrupt we test this and other implications of the model using country and individual level data on social capital and beliefs about government s role as well as on changes in beliefs and in trust during the transition from socialism

unemployment labour markets and structural change in eastern europe labour markets in eastern europe michael burda unemployment is a major concern in the transforming economies of central and eastern europe the modern flow approach to labour markets suggests both that unemployment is an important component of the transformation process and that the labour market institutions adopted will influence the rate of unemployment in the long run to date eastern european countries exhibit considerable divergences in several of these institutions especially in unemployment benefit systems collective bargaining structures and active labour market policies an aggregate matching function is successfully estimated for data from czech and slovak employment offices emerging labour markets in the east function not so differently from those in the west the implied dynamics make both big bang and benign neglect unattractive strategies for transformation a mixed bang is more appropriate quantitative evidence about the effects on unemployment of different labour market institutions in oecd countries is used to make long term projections of equilibrium rates of unemployment in central and eastern europe given the labour market institutions now in place there with the possible exception of the czech republic high unemployment is likely to be pervasive and persistent

institutional path dependence in climate adaptation coman s some unsettled problems of irrigation districts that emerged in the american west in the late nineteenth and early twentieth centuries in response to aridity to facilitate agricultural water delivery use and trade raise the transaction costs today of water markets these markets are vital for smooth reallocation of water to higher valued uses elsewhere in the economy and for flexible response to greater hydrological uncertainty this institutional path dependence illustrates how past arrangements to meet conditions of the time constrain contemporary economic opportunities they cannot be easily significantly modified or replaced ex post

groundwater use under incomplete information abstract this paper introduces a game theoretic model of groundwater extraction in a two cell aquifer under incomplete information a novel assumption is that individual users have incomplete knowledge of the speed of lateral flows in the aquifer although a user is aware that his neighbor s water use has some influence on his future water stock he is uncertain about the degree of this impact we find that the lack of information may either increase or decrease the rate of water use and welfare in a two period framework the relevant characteristic is the ratio of the periodic marginal benefits of water use depending on whether this ratio is convex or concave the average speed with which the aquifer is depleted decreases or increases when users learn more about the local hydrologic properties of groundwater in principle welfare may decrease even in cases when the groundwater allocation is closer to the efficient groundwater allocation

shadows of the past the effect of communist heritage on employee consultation following research on transition economies in central and eastern europe cee and having been motivated by arguments pertaining to the business systems approach the authors propose that the existence of a communist heritage decreases the likelihood that employees will be consulted during organizational change processes results based on 23 876 firms across 27 of the european union eu 27 countries support this proposition moreover the likelihood of direct consultation decreases with the existence of formal employee representation and an increasing share of foreign ownership in firms located in cee countries the authors discuss these findings in the context of organizational democracy research and the recent literature on transition economies and contribute to a more comprehensive understanding of participative decision making processes in organizations

restricting the market for quota an analysis of tobacco production rights with corroboration from congressional testimony regulatory programs that restrict output levels often impose restrictions on the transfer of rights to produce or to use particular inputs in this paper we use a unique cross section time series data set from north carolina to quantify the welfare effects of transfer restrictions for poundage quota under the u s flue cured tobacco program we find that the deadweight costs of such restrictions are small but that the distributional effects are substantial we analyze congressional testimony on quota transfer legislation and conclude that our estimates of the distributional effects are consistent with expressed views of market participants

current issues in the economics of groundwater resource management the issue of groundwater management remains a practical concern in many regions throughout the world while water managers continue to grapple with the question of how to manage this resource in this article we attempt to bring the most advanced and appropriate tools to bear on the issue of resource allocation involving groundwater our objective is to demonstrate the state of the art in the literature on ways to think about this complex resource and to deal with the important economic issues emanating from its complexity we present the conceptual framework within which economists examine the elements interacting in the management of groundwater resources indicate why the role of the market is limited with respect to the price of this very complex resource and point to the mechanisms that can pull competitive groundwater price and quality graded quantity of groundwater in line with their equilibrium levels in particular we critically review economic models of groundwater use examine the potential for groundwater management discuss the difficulties encountered in the estimation of the relevant control variables of such models and identify the advantages and limitations of the instruments devised for the efficient use allocation of this resource finally we argue that devised regulatory schemes usually ignore the information and knowledge needed for their implementation and we suggest a core of conditions necessary for successful groundwater management reforms

the potential for water market efficiency when instream flows have value most of the effort being expended to revise western water policy concerns the maintenance of instream waters to the exclusion of traditional diversionary interests absent from the economics literature is a theoretical treatment addressing the interface between diversionary and instream water uses at issue is the potential for refining market operations to accomplish efficient allocation in the presence of both diversionary and instream uses optimization methods are employed to examine this issue in a highly generalized framework if a specific structure is adopted markets and other incentive based policies are demonstrated to be capable of efficient water allocation

the effects of well management and the nature of the aquifer on groundwater resources we compare groundwater use under collective well management in china where village leaders allocate water among households and under private well management where farmers either pump from their own wells or buy water from wells owned by other farmers villages are divided into connected or isolated groups depending on whether there are lateral groundwater flows between aquifers underlying a village and neighboring ones in rural china households under collective well management use less water even under collective management households located in connected villages use more water indicating that the connectedness of the aquifers may undermine leaders incentives to conserve water

competitive versus efficient extraction of a common property resource the groundwater case abstract in this paper socially optimal and private extraction of a common property aquifer are compared open loop equilibrium and feedback equilibrium in linear strategies have been computed to characterize private extraction the use of these two equilibrium concepts allows us to distinguish between cost and strategic externalities as long as the open loop solution captures only the cost externality and the feedback solution captures both the results show that strategic behaviour increases the overexploitation of the aquifer compared to the open loop solution however if the groundwater storage capacity is large the difference between the socially optimal and private extraction the latter characterized by a feedback equilibrium is negligible

the institutional hiatus in economies in transition and its policy consequences the collapse of communism created an institutional hiatus in the economies of eastern europe and the soviet union because the old political and economic institutions were destroyed more rapidly than they could be replaced by those of a market economy the importance and complexity of institution building has been played down in the mainstream economists consensus which has presented a highly restricted set of policy options as the only route to a vibrant market economy this paper argues that entrepreneurship provides a missing conceptual link between enterprise reform and the creation of market institutions a number of measures for closing the institutional hiatus in transition economies are considered copyright 1997 by oxford university press

potential for tradable water allocation and rights in jordan this paper estimates the costs of buying water use rights from farmers located in the mafraq azraq basin in jordan the farmers water supply curve is estimated using data gathered from a contingent valuation survey and nonparametric procedures estimation results indicate that a total supply of 29 million m 3 could be periodically purchased from farmers at an annual price of approximately jd 0 23 m 3 1 jd 0 70 us or a total cost of about jd 6 8 million per year

econometric models of asymmetric price transmission abstract in this paper we review the existing empirical literature on price asymmetries in commodities providing a way to classify and compare different studies that are highly heterogeneous in terms of econometric models type of asymmetries and empirical findings relative to the previous literature this paper is novel in several respects first it presents a detailed and updated survey of the existing empirical contributions on price asymmetries in the transmission mechanism linking input prices to output prices second this paper presents an extension of the traditional distinction between long run and short run asymmetries to new categories of asymmetries such as contemporaneous impact distributed lag effect cumulated impact reaction time equilibrium and momentum equilibrium adjustment path regime effect regime equilibrium adjustment path each empirical study is then critically discussed in the light of this new classification of asymmetries third this paper evaluates the relative merits of the most popular econometric models for price asymmetries namely autoregressive distributed lags partial adjustments error correction models regime switching and vector autoregressive models finally we use the meta regression analysis to investigate whether the results of asymmetry tests are not model invariant and find which additional factors systematically influence the rejection of the null hypothesis of symmetric price adjustment the main results of our survey can be summarized as follows i each econometric model is specialized to capture a subset of asymmetries ii each asymmetry is better investigated by a subset of econometric models iii the general significance of the f test for asymmetric price transmission depends mainly on characteristics of the data dynamic specification of the econometric model and market characteristics overall our empirical findings confirm that asymmetry in all its forms is very likely to occur in a wide range of markets and econometric models

futures contracts in water leasing an experimental analysis using basin characteristics of the rio grande nm providing for increased water demands during periods of persistent drought and climatic variability may require water managers users and planners to think differently about how water resources are allocated a water marketing institution that allows water rights holders to reallocate water on a temporary basis could overcome these challenges with minimal conflict in this paper a water marketing institution that allows for the temporary reallocation of water rights in a spot and futures market is investigated the results provide insight into three key questions 1 how does trading impact the physical system 2 does the value of water differ by trading agents 3 how is economic welfare redistributed as a result of trading results of experimental treatments display minor impacts to the physical system that prices differ across the different type of trading agents and the addition of a futures market has the ability to decrease market prices while increasing economic welfare as a futures market allows users to hedge against future water uncertainty

the dynamics and volatility of prices in a vertical sector this paper studies the evolving distribution of prices in a vertical sector in the presence of market cycles it investigates the dynamic linkages between farm and retail prices with an application to the chinese pork sector the econometric approach relies on a quantile autoregressive qar model that provides a flexible representation of the dynamics of price volatility it investigates the presence and nature of price cycles and their implications for price transmission we document that the marketing margin is more sensitive to changes in consumer income than in feed cost in addition rising feed cost increases the amplitude of the cycle while higher consumer income increases the period of the cycle

the role of common pool problems in irrigation inefficiency a case study in groundwater pumping in mexico groundwater depletion is a serious problem in mexico several policy alternatives are currently being considered in order to improve the efficiency of irrigation water use so that extraction of groundwater is diminished an understanding and quantification of different sources of inefficiency in groundwater extraction is critical for policy design survey data from a geographically extensive sample of irrigators is used to gauge the importance of common pool problems on input specific irrigation inefficiency results show that mechanisms of electricity cost sharing implemented in many wells have a sizable impact on inefficiency of irrigation application moreover irrigation is very inelastic to its own unitary cost therefore results suggest that policies aimed at eliminating electricity cost sharing mechanisms would be significantly more effective than electricity price based policies in reducing irrigation application results also show that well sharing does not affect groundwater pumping significantly suggesting either a limited effect of individual pumping on water level or absence of strategic pumping by farmers sharing the wells

the dynamic relationship between the prices of adrs and their underlying stocks evidence from the threshold vector error correction model this paper sets out to estimate the dynamic relationship that exists between the prices of adrs and their underlying stocks in both the short run and the long run using a number of recent developments of the threshold cointegration framework the empirical results support the notion of nonlinear mean reversion of the prices of adrs and their underlying stocks

water quantity management in a heterogeneous landscape with farsighted farmers agricultural production contributes to many environmental problems in semi arid areas agricultural irrigation causes the so called waterlogging phenomenon this phenomenon is both spatial and dynamic since percolation depends on soil quality summed up in landscape heterogeneity and evolves along time furthermore farmers can be farsighted with respect to their contribution to percolation we study regulation schemes to be implemented to restore the socially optimal spatial and temporal production plan of farmers in such a context we show that both a temporal tax on percolation and a spatio temporal tax on inputs both at the extensive and at the intensive margin are efficient for the restoration of the socially optimal solution furthermore a numerical example demonstrates that the consequences of implementing a fiscal scheme designed for myopic farmers whereas they are farsighted depends on the distribution of soil quality

price transmission and market integration vertical and horizontal price linkages for salmon relationships between prices are of interest when testing for market integration as well as analyses of supply chains a feature that has received little attention is that if two supply chains are linked by market integration at some stage then the whole supply chain will be linked furthermore the leading price in such a system can be in one supply chain and will not be revealed in market integration studies or analysis of a single supply chain an empirical analysis is provided for the supply chains for salmon which originates in norway and the united kingdom and is then sold at retail level in france as smoked salmon we find a high degree of price transmission in both supply chains as well as integrated markets

disentangling nonlinearities in the long and short run price relationships an application to the us hog pork supply chain increased concentration at the retail food processing and farm input manufacturing levels has brought increased attention to patterns in retail to farm price spreads most studies documenting asymmetric price transmission focus on nonlinear error correction processes as opposed to the current study which analyses potential nonlinearities in the long run relationship between the farm and retail prices the null hypothesis of nonlinearity in the long run relationship between farm and retail prices in the us hog pork supply chain is rejected in favour of a smooth transition cointegration stc framework the stc framework predicts downward price stickiness in retail prices the predicted residuals of the nonlinear model are used to investigate whether it is possible to disentangle nonlinearity in the long run price relationship from nonlinearity in the adjustment towards the long run equilibrium the results underline the importance of testing for linearity in the long run price relationship before modelli

institutions transaction costs and entry mode choice in eastern europe the process of change from a centrally planned system to a market economy generates an institutional framework that is only partially reformed and therefore inconsistent and unstable this leads to high transaction costs for economic agents multinational enterprises entering transition countries have to adapt their strategies to the local institutions and reduce exposure to highly imperfect markets this paper analyzes how the costs of organizing business in transition environments influence entry mode choice the empirical results show that host country institutions in transition economies have an impact on the choice of entry modes moreover different mechanisms determine the internalization of managerial and technological knowledge

dynamic hedge ratio for stock index futures application of threshold vecm this study represents one of the first papers in stock index futures arbitrage literature to investigate the effects of arbitrage threshold on stock index futures hedging effectiveness by using threshold vector error correction model hereafter threshold vecm moreover in contrast to prior studies focusing on examining case studies involving mature stock markets this study not only adopts us s p 500 stock market as the sample but also adds an analysis of one emerging stock market hungarian bsi and examines the differences between them finally this investigation employs a rolling estimation process to examine the impact of arbitrage threshold behaviours on the setting of futures hedging ratio the empirical findings of this study are consistent with the following notions first arbitrage behaviour reduces co movement between futures and spot markets and increases the volatility of both futures and spot markets second this article denotes the outer regime of futures spot market for the case of hung

joint quantity quality management of groundwater economic literature on groundwater managementhas traditionally been split into two areas there are papers that evaluate different schemes of dynamicaquifer management considering that pumping costs vary with stock but ignoring water quality on the other hand there are papers that considercontamination problems caused by specificpollutants this paper presents two alternative models for joint quantity quality management and it shows that existing models are in fact special cases of these the framework isdynamic and considers both the stock of waterquantity and a stock measure of water quality optimal taxes are derived and shown to be different from those in existing quantity only or quality only models implementationproblems are briefly discussed

strategic behavior and efficiency in the common property extraction of groundwater groundwater has always been regarded as a common property resource where entry is restricted by land ownership and private exploitation is inefficient in 1980 gisser and sanchez presented a first estimation of this inefficiency cornparing socially optimal exploitation with private competitive exploitation using a model with linear water demand average extraction cost independent of the rate of extraction and linearly decreasing with respect to the water table level they characterized the private exploitation of the aquifer assuming that farmers are myopic and choose their rate of extraction to maximize their current profits whereas optimal exploitation is obtained by maximizing the present value of the stream of aggregate profits their results show that if the storage capacity of the aquifer is relatively large the difference between the two systems is so small that it can be ignored for practical consideration this result has been called the gisser sanchez rule by nieswiadomy 1985 and it has and important policy implication regulation of the resource does not seem justified since the profits it brings are not very high 1

optimal groundwater extraction under uncertainty and a spatial stock externality we introduce a model that incorporates two important elements to estimating welfare gains from groundwater management stochasticity and a spatial stock externality we estimate welfare gains resulting from optimal management under uncertainty as well as a gradual stock externality that produces the dynamics of a large aquifer being slowly exhausted this groundwater model imposes an important aspect of a depletable natural resource without the extreme assumption of complete exhaustion that is necessary in a traditional single cell bathtub model of groundwater extraction using dynamic programming we incorporate and compare stochasticity for both an independent and identically distributed as well as a markov chain process for annual rainfall we find that the spatial depletion of the aquifer is significant to welfare gains for a parameterization of a section of the ogallala aquifer in kansas ranging from 2 9 to 3 01 which is larger than those found previously over the region surprisingly the inclusion of stochasticity in rainfall increases welfare gains only slightly

dynamic model for market competition and price rigidity abstractthis article presents a price floor model in which durability unit costs and production period are factors in explaining price rigidity this article elaborates that cost structure plays an essential role in resolving the inconclusive relationship between market concentration and price rigidity when the industry is characterized by decreasing returns of scale the degree of price flexibility decreases as market competition intensifies the reverse is true when the industry exhibits increasing returns of scale the factors that cause price rigidity also foster price adjustment asymmetry and price adjustment lag during times of recession the model exhibits upward price flexibility as costs increase but downward price rigidity as costs decrease even under forward looking expectations the way in which firms adjust prices could look as though they have adaptive expectations if price stickiness is a characteristic of market competition then public policies determined by price level could be too

the dynamic efficiency costs of common pool resource exploitation we conduct the first empirical investigation of common pool resource users dynamic and strategic behavior at the micro level using real world data fishermen s strategies in a fully dynamic game account for latent resource dynamics and other players actions revealing the profit structure of the fishery we compare the fishermen s actual and socially optimal exploitation paths under a time specific vessel allocation policy and find a sizable dynamic externality individual fishermen respond to other users by exerting effort above the optimal level early in the season congestion is costly instantaneously but is beneficial in the long run because it partially offsets dynamic inefficiencies jel d24 q21 q22

does inequality lead to greater efficiency in the use of local commons the role of strategic investments in capacity abstract this paper examines how inequality in access to credit affects the strategic behavior of users of a common resource in their investment and extraction decisions a dynamic two stage game is developed in which agents choose the level of sunk investment in capacity and the consequent extraction path the results show that agents invest in excess capacity except when inequality is very high the relation between inequality and efficiency in resource extraction is found to be non monotonic with the steady state resource stock being closest to the optimal level when either inequality is very high or very low

inventories and sticky prices more on the microfoundations of macroeconomics the role of inventories in making prices sticky is studied by analyzing a dynamic linear quadratic model of a monopoly firm facing stochastic demand but able to store its finished goods in inventory it is shown that in contrast to the usual presumption firms that exhibit the smallest output responses to demand fluctuations may also exhibit the smallest price fluctuations specifically firms which have very flexible inventory storage facilities or are subjected to very transitory demand shocks will rely on inventories as buffers and will change neither production nor price very much on the other hand firms which have very inflexible storage facilities or whose demand shocks are quite permanent will display large swings in both price and output the standard assumption about inventory carrying costs that has been used in the literature that they are linear is shown to imply that production is impervious to fluctuations in demand it is also established that prices may respond more strongly to positive demand shocks than to negative ones if it is impossible to hold negative inventories i e to have unfilled orders the model offers an explanation for stickiness in relative prices however under certain circumstances it may help explain the persistence of inflation this abstract was borrowed from another version of this item

business cycle asymmetry a deeper look this paper distinguishes two types of asymmetry in business cycles deepness and steepness deepness is defined as the characteristic that troughs are further below trend than peaks are above most previous research has focused exclusively on steepness which refers to cycles in which contractions are steeper than expansions a test for deepness is proposed and applied to u s post war quarterly unemployment real gnp and industrial production evidence of deepness is found for unemployment and industrial production while the evidence for real gnp is weaker previous evidence of steepness in unemployment is confirmed

the story of the moment risk averse cypriot farmers respond to drought management this article illustrates the importance of estimating risk preferences when evaluating water policy using agricultural production data from the kiti region of cyprus we estimate farmers risk preferences a la antle journal of business and economic statistics 1 192 201 1983 american journal of agricultural economics 69 509 22 1987 and show sensitivity to higher order moments of profit such as skewness we show that farmers in the kiti region are risk averse with risk premiums in the region of 20 of expected profit we use these estimates to analyse the impact of a water quota from the perspective of three policy makers who differ only in their understanding of farmers risk preferences we show in the case of kiti that policy makers who model risk preferences incorrectly that is either a assume risk neutrality or b ignore down side risk wrongly predict the magnitude and direction of input responses and therefore the magnitude of welfare changes this highlights the importance of accomm

using threshold cointegration to estimate asymmetric price transmission in the swiss pork market this paper employs threshold cointegration tests that allow for asymmetric adjustment towards a long run equilibrium relationship to examine the relationship between producer and retail pork prices in switzerland the short run adjustments are also examined with asymmetric error correction models that are compared to the conventional symmetric error correction models the results indicate that price transmission between the producer and retail levels is asymmetric in the sense that increases in producer prices that lead to declines in marketing margins are passed on more quickly to retail prices than decreases in producer prices that result in increases in the marketing margins

do gasoline prices respond asymmetrically to crude oil price changes the authors test and confirm that retail gasoline prices respond more quickly to increases than to decreases in crude oil prices among the possible sources of this asymmetry are production inventory adjustment lags and market power of some sellers by analyzing price transmission at different points in the distribution chain the authors attempt to shed light on these theories spot prices for generic gasoline show asymmetry in responding to crude oil price changes which may reflect inventory adjustment effects asymmetry also appears in the response of retail prices to wholesale price changes possibly indicating short run market power among retailers

price transmission asymmetric adjustment and threshold effects in the cotton supply chain a case study for vidarbha india this study examines price transmission asymmetries in vidarbha s india cotton supply chain from 2002 to 2012 the analysis takes account of thresholds in price adjustments toward their long run equilibrium the first stage considers the price dynamics between international and indian domestic cotton prices the second stage considers price transmission from domestic to farm gate cotton prices in vidarbha results from the first stage indicate that indian and international cotton markets are well integrated in contrast the second stage reveals significant threshold type nonlinearities as well as asymmetries in price transmission between domestic and farm gate prices the short run dynamics suggest that the pass through from domestic to farm gate prices is larger when domestic prices decrease than when they increase moreover back of the envelope calculations suggest that the loss in revenue for a typical farmer from a decrease in domestic price is larger than the gains from an increase in domestic price of the same magnitude the implication is that traders benefit from price fluctuations at the expense of farmers evidence from fieldwork in vidarbha suggest that asymmetries revealed in this analysis may be linked to trader s market power and inadequate market information among farmers
