challenges to proponents of common property recource systems despairing voices from the social forests of zimbabwe abstract there is a fair degree of misplaced optimism about common property resource cpr management in investigating common property issues for woodlands in communal areas in zimbabwe we are struck by the numerous case studies showing a breakdown of local institutions for cpr management and the lack of any emerging alternative institutions for such management there are a number of contributing economic social and ecological factors to this phenomenon we argue that the formal rule based systems that form the cornerstones of the proposed cpr systems are far removed from the current institutional systems rooted in norm based controls we suggest that advocacy of cpr systems has to be tempered with critical analysis

activity choice labor allocation and forest use in malawi this article examines the determinants of activity choice affecting forest use among low income households in malawi data from three villages are used to estimate a system of household labor share equations for maize production forest employment and non forest employment a system estimation approach is used to identify factors influencing the competing and synergistic livelihood strategies which households undertake at the forest margin results from constrained maximum likelihood estimation indicate heightened incentives to degrade forests when returns to forest use are high factors reducing forest pressure include favorable returns to non forest employment secondary education of the household head and wealth

property rights externalities and resource degradation locating the tragedy abstract resource degradation in the third world is largely driven by the demands of farm households for fuelwood and land for agriculture since resources are often controlled through indigenous systems of property the tragedy of the commons has been used to explain resource degradation as a result private property is suggested as a solution to resource degradation a dynamic model capable of examining household incentives for resource use under private and common property is developed results of the model reject the conventional wisdom that gives rise to the presumed optimality of private individual property in natural resources and the correlated indictment of group management regimes

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

the ambiguous impact of inequality on local resource management abstract the impact of inequality on the ability of human groups to undertake successful collective action is investigated with special reference to overexploitation of common property resources in voluntary provision problems on the one hand inequality has an ambiguous impact on the feasibility of the efficient outcome even though better endowed agents contribute more to collective action in regulated settings on the other hand inequality tends to reduce the acceptability of available regulatory schemes and therefore to make collective action more difficult

the role and behaviour of commercial property investors and developers in french urban regeneration the experience of the paris region summary this paper provides an analysis of the factors underlying private investment decisions concerning property development with specific reference to urban regeneration in the french context it is based on the results of a behavioural survey and mca analysis of the behaviour patterns and motivations of active private investors and developers in the french commercial property markets and their involvement in french urban regeneration initiatives the pattern of investment and development activity over the 1997 2002 french property market recovery period has been studied and a typology of actors set up based on their investment policy for these property markets the findings indicate that property investors in urban regeneration essentially seek speculative developments and short term investments

the tragedy of the commons in cote d ivoire agriculture empirical evidence and implications for evaluating trade policies expansion of cultivated land diminishes the extent of forestlands or reduces the length of fallow periods and hence reduces the amount of natural vegetation the increase in land under cultivation has a direct output increasing effect at the cost of reducing natural capital and agricultural productivity the evidence for western cote d ivoire is consistent with and provides an explanation for the declining agricultural productivity observed in sub saharan africa during the past few decades this article uses a theoretical model to determine the level of land cultivation that maximizes village income using data from cote d ivoire for 1985 87 an important part of the land is under common property usually at the village level the results show that farmers do not internalize even a small fraction of the external cost of biomass in their land allocation decisions the lack of internalization of the social cost of the biomass resource leads to large income losses at the village level as much as 14 percent of village income these losses are many times larger than the usual estimates for conventional distortions

environmental externalities in traditional agriculture and the impact of trade liberalization the case of ghana abstract this paper provides a framework for the evaluation of trade policies that explicitly considers the effects of such policies on the environmental resources biomass in doing this we estimate the effects of biomass as a factor of agricultural production and test the hypothesis that farmers efficiently exploit biomass a resource held in common property the main findings are i biomass is an important factor of production in ghanian agriculture ii the biomass resource is exploited beyond the socially optimal level iii a deepening of trade liberalization is likely to induce further losses of biomass and deforestation and iv national income is likely to fall in response to further trade liberalization

an optimal path to extinction poverty and resource degradation in the open agrarian economy this paper constructs a model of the open agrarian economy in order to explore the tendency of many such economies to evolve along paths characterised by severe environmental degradation it pays special attention to the importance of commodity prices and the transfer system in determining agricultural activity levels in ecologically delicate systems

economic development and environmental management in the uplands of southeast asia challenges for policy and institutional development using a philippine case study site the forces driving the recent evolution of economic behavior and institutional arrangements in upland and forest margin areas of southeast asia are considered in early modern development subsistence agriculture using long phase forest fallow rotations and regulated by customary law was replaced by more intensive commercially oriented farming systems a process heavily influenced by internal migration to the agricultural frontier traditional land and resource use institutions were quickly displaced during this shift both de facto through the actions of colonists and de jure through the state s assertion of ownership over forests and uplands and the introduction of private title to agricultural lands yet the effective implementation of natural resource use constraints lagged substantially behind the pace of agricultural development and forest exploitation resulting in a period in which high demand for such resources coincided with virtually open access these processes were noticeably subject to the influence of policies and reforms affecting markets prices and institutions

common property institutions and sustainable governance of resources abstract the literature on common property based resource management comprises many important studies that seek to specify the conditions under which groups of users will self organize and sustainably govern resources upon which they depend using three of the more comprehensive such studies and with an extensive review of writings on the commons this paper demonstrates that the enterprise of generating lists of conditions under which commons are governed sustainably is a flawed and impossibly costly research task for a way out the paper examines the relative merits of statistical comparative and case study approaches to studying the commons it ends with a plea for careful research design and sample selection construction of causal mechanisms and a shift toward comparative and statistical rather than single case analyses such steps are necessary for a coherent empirically relevant theory of the commons

the financialization of business property and what it means for cities and regions halbert l henneberry j and mouzakis f the financialization of business property and what it means for cities and regions regional studies the papers in the special issue examine the strategies and practices of investors and their relations with other actors involved in the production of business property although the globalization of these activities has occurred largely in the last 10 20 years it has prompted marked changes in the geography of commercial property investment international capital has flowed to a limited number of favoured locations but because of the spatial fixity of real property local actors and institutions remain an important influence on investment decisions this poses challenges for urban development and regeneration policies that depend on private investment capital

corporatism labor unions and the safety net abstract this paper models corporatism as the attainment of outcomes superior to those when individual parties act alone this idea is developed in the context of union government interactions in the determination of wages and unemployment benefits a central finding is that while corporatism is welfare improving for the actors involved it yields few clear implications for the evolution of wages employment benefits or output it may therefore be unwise to employ corporatism indices in macroeconometric analyses without explicitly accounting for bargaining structures information and especially preferences

state and peasant in contemporary china the political economy of village government this is a study of peasant state relations and village politics as they have evolved in response to the state s attempts to control the division of the harvest and extract the state defined surplus to provide the reader with a clearer sense of the evolution of peasant state relations over almost a forty year period and to highlight the dramatic changes that have taken place since 1978 1 have divided my analysis into two parts chapters 2 through 7 are on maoist china and chapters 8 and 9 are on post mao china the first part examines the state s grain policies and patterns of local politics that emerged during the highly collectivized maoist period when the state closed free grain markets and established the system of unified purchase and sales tonggou tongxiao the second part describes the new methods for the production and division of the harvest after 1978 when the government decollectivized agriculture and abolished its unified procurement program

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

sustainability and the anchoring of capital negotiations surrounding two major urban projects in switzerland theurillat t and crevoisier o sustainability and the anchoring of capital negotiations surrounding two major urban projects in switzerland regional studies this article deals with the anchoring of mobile financial capital in the city and urban sustainability illustrated by a case study in the swiss context it develops the theory that new forms of negotiation are appearing around urban projects development construction firms are playing a central role they are capable of evaluating and translating the multiple dimensions of a project and certain sustainability challenges into financial terms in a way that permits the anchoring of capital in the city in parallel the issue of sustainability depends greatly on the capacity of the local actors to negotiate with the promoters of urban projects

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

unemployment insurance and union wage setting the authors examine alternative systems of financing unemployment insurance benefits in an economy with wage sett ing unions where as in some nordic countries each union runs its o wn unemployment insurance system it is shown that a higher lump sum grant to the union s unemployment insurance fund increases employment whereas higher marginal subsidies have ambiguous effects an unempl oyment insurance tax on wages has no effect on employment whereas an unemployment insurance tax on profits unambiguously increases employ ment the authors also analyze a case where wages are set at the firm level and premiums at the industry level copyright 1988 by the editors of the scandinavian journal of economics

the macroeconomics of social pacts in this paper we analyze macroeconomic interactions between trade unions the central bank and the fiscal policymaker we explicitly model unions concern for public expenditure paving the way for an analysis of the potential gains from cooperation between the fiscal policymaker and the unions i e the so called corporatist or social pacts that have characterized economic policies in a number of european countries in the last few decades we also highlight the profoundly different incentives generated by institutional arrangements such as the maastricht criteria and the stability and growth pact the former has unambiguously induced more efficient outcomes the latter is likely to backfire

optimal management of a confined groundwater system abstract dynamic programming is applied to a relatively simple economic and hydrologic model of a confined aquifer system in southwest montana to determine an optimal interseasonal allocation schedule the derived decision rule demonstrates the economic advantage of maintaining a confined groundwater system while localized intraseasonal loss of the artesian pressure may occur it is important to maintain this pressure from year to year because of its role in reducing extraction costs the welfare gap as measured by differences in the net present value of economic returns to the basin under an optimal use policy versus an uncontrolled common pool situation is not trivial sensitivity analysis indicates that assumptions about uniformity of land productivity vis a vis their impact on the shape of the returns function the discount rate and the level of electric power rates are particularly critical with respect to the magnitude of the commonality problem

benefits from groundwater management magnitude sensitivity and distribution empirical estimates of benefits from groundwater management are reported for an area in california with heavy reliance on groundwater supplies benefits are quite sensitive to the water demand schedule and interest rate but less sensitive to other parameters however in all cases considered the increases in welfare from groundwater management are less than ten percent tax revenues received under a system of pump taxes are four to five times as large as the benefits from management thus groundwater users gain under a system of quotas but may suffer substantial welfare losses under pump taxes

familiarity and the determination of yields for regional office property investments in the uk henneberry j and mouzakis f familiarity and the determination of yields for regional office property investments in the uk regional studies this paper examines how effectively investment yields incorporate spatial variations in risks and returns into property prices it is hypothesized that the pricing of property investments in non core uk regions is affected by a pure familiarity heuristic adopted by investors based in london consequently the determination of office yields is based not on the intrinsic investment characteristics of regional markets but on a core market benchmark combined with a regional premium this results in very long term mispricing patterns with implications not just for the office property investment market but also for the regions especially those outside the core

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

property rights labour markets and efficiency in a transition economy the case of rural china we investigate the consequences of imperfect factor market development for farm efficiency in north china we estimate the extent to which an inverse relationship in farm productivity can be attributed to the administrative as opposed to market allocation of land combined with unevenly developed off farm opportunities using a new household survey we find considerable inefficiency in the use of labour this inefficiency is alleviated by external labour markets and to a limited degree by administrative reallocations the reallocations do not go far enough however which raises important questions about con straints on rental activity and property rights formation more generally jel classification q15 012

leveraging finance capital urban change and self empowerment of real estate developers in india this paper questions the effects of the financialisation of indian real estate markets with a focus on the bangalore city region research on southern cities has concluded that globally connected but locally embedded real estate developers contribute to anchoring transnational investment yet the acknowledged dearth of studies on the real estate industry in post liberalisation india limits our understanding of the ongoing empowerment of local urban actors including developers adopting a cultural political economy perspective the paper analyses how developers leverage finance capital to achieve greater economic and political agency and thus contribute to the material symbolic and political transformations of cities it first demonstrates that finance capital has sustained bangalore based developers growth strategies throughout southern india subsequently developers shape the materialities of metropolises via a piecemeal juxtaposition of medium sized developments although this may occasionally meet government strategies for modernising their cities it more often than not constitutes an understudied obstacle to states mega projects that are outdone by developers ability to work through the intricacies of local land markets and bureaucracies furthermore having become dominant city builders developers are in a situation to circulate representations concerning what the desirable city should be such narratives aim at inserting local real estate markets into globalising financial commodity chains while also legitimating developers own role consequently developers attempt to promote with some success prescriptions in favour of state reforms and the adoption of pro urban growth policies the ongoing financialisation of urban production thus participates in the self empowerment of developers in india s cities

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

information access income distribution and the environmental kuznets curve abstract recent empirical studies have tested the hypothesis of an environmental kuznets curve ekc focusing primarily on the relationship between per capita income and certain types of pollutant emissions given the stock nature of many pollution problems emissions only partially account for the environmental impacts moreover almost all of the studies have given consideration to little more than income levels as explanatory variables this paper empirically tests the hypothesis of the ekc existence for a stock sensitive indicator that is the percentage of protected area pa within national territory it does theorize that economic growth is a necessary condition in order to better address environmental issues but it also stresses that other variables income distribution education information accessibility may play a fundamental role in determining environmental quality contrary to other studies that mainly focus on the calculation of the income level corresponding to the transition point this paper is more concerned with the calculation of environmental quality corresponding to that transition point that is the minimum level of environmental quality that a country is willing to accept this paper highlights the idea that if the transition point is determined primarily by income level social policies determine the level of environmental quality corresponding to that point

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 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

natural resources prices export policies and deforestation the case of sudan abstract environmental destruction is often the result of price policies for primary commodities that determine how individuals will use and abuse natural resources in this paper we analyze how domestic policies under colonial and independent governments in sudan contributed to acacia senegal deforestation and the demise of the international gum arabic trade when primary commodities are produced from environmentally beneficial species such as acacia senegal trees the impact of a declining market for the primary commodity will have economic and ecological repercussions on other sectors in the economy poverty and risk are central to this process

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

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

finance business property and urban and regional development halbert l henneberry j and mouzakis f finance business property and urban and regional development regional studies compared with other factors of production the supply of business property and its role in urban and regional development has received comparatively little attention traditional analyses assume that the supply of such property responds to demand in a relatively unproblematic way however there is evidence that institutional structures and processes in the property and capital markets have produced regional imbalances in the quantity quality and price of business accommodation benefiting some places and handicapping others such imbalances are present to different degrees internationally and their characteristics and causes are similarly varied the special issue addresses this gap in knowledge

building cities on financial assets the financialisation of property markets and its implications for city governments in the paris city region the 2008 global financial meltdown has redirected attention to the entwinement of financial markets and the urban built environment against that background recent works in urban political economy have focused on how city governments support the rent maximisation strategies of landowners thereby reinforcing the increasing tendency to treat land as a financial asset harvey 1982 2006 however this perspective paradoxically understates the importance of market finance actors neglecting to demonstrate how in practice such financial investors who have been shown to adopt selective investment practices shape urban redevelopment projects in this article the role of financial investors is analysed through a case study of a large scale redevelopment project on the outskirts of the paris city region city of saint ouen the analysis of negotiations over urban design and economic development issues raised by property developers seeking to fashion commercial properties as investment assets reveals the unevenness of a local authority s ability to implement an agenda that potentially diverges from the expectations of financial investors accordingly given the growing importance of investors in the ownership of the built environment the article considers urban redevelopment as the outcome of power relations that originate in the circulation of investors expectations these expectations are met through translating market finance categories risk return and liquidity into elements of the urban fabric this bears substantial consequences for policy making given the current context of austerity as municipal authorities are increasingly constrained to rely on property markets urban redevelopment projects are thereby increasingly shaped to provide investment assets for financial investors

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

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

economic incentives and conservation crowding in social norms in a groundwater commons abstract price based interventions can be corrective where users extract from a common resource but may also impact existing social norms often crowding them out in contrast i find a pumping fee implemented by a group of irrigators in southern colorado effectively crowds in pro conservation norms enhancing the financial incentive s impact using a unique spatially oriented panel data set of groundwater wells i separate the direct role of increased pumping costs from the indirect effect transmitted through altered conservation norms to quantify conservation behavior i estimate how pumping at one well responds to pumping at nearby wells using instrumental variables to address simultaneity bias and interact that behavior with a difference in difference framework to assess the influence of the intervention in the preferred specification the fee directly accounts for approximately 74 of the reduced pumping and the remaining 26 comes from crowding in conservation norms

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

the approach of institutional economics this paper assesses the old institutional economics it emphasizes the importance of key old institutionalist themes concerning the necessity of habits and rules and the role of institutions a problem in the alternative theoretical program of the new institutionalism is the untenability of its assumption of an original institution free market or state of nature even optimizing behavior requires the prior existence of habits and rules although it still lacks a complete and systematic theory the evolutionary approach of the old institutionalists tackles the problem of the interactive relationship of actor to structure without analytical reduction to one or the other

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

financing property s contribution to regeneration attracting investment and finance into inner city and other renewal areas poses particular difficulties and is frequently reliant on strong public sector commitment through special incentives or other mechanisms to provide the conditions to lever private sector activity this paper initially links the concept of market failure and the rationale for regeneration and examines policy responses from uk european and us perspectives followed by a consideration of public and private sector financing approaches international perspectives draw particularly upon the use of tax based mechanisms in regeneration notably those used in the us in the european context the paper highlights implications for regeneration stemming from the interpretation of state aid rules and competition policy conclusions reflect upon the complexity of regeneration and the importance of the different stakeholders within the regeneration process

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

third wave sustainability smart growth and regional development in the usa krueger r and gibbs d third wave sustainability smart growth and regional development in the usa regional studies increasingly concepts of sustainable development are finding their way into local and regional development strategies this is also true in the usa though not through the local agenda 21 process as is the case in much of the rest of the world the approach to sustainable development in the usa is a set of policy approaches collectively referred to as smart growth smart growth is sometimes referred to as a uniquely american variant of sustainable development in contrast to local agenda 21 smart growth has captured the imagination of american policy makers at all spatial scales many have lauded smart growth as a market based approach that promotes the tripartite concerns of sustainability this paper positions smart growth in the context of broader political economic change and scrutinizes its incentive based approach through a case study from the boston massachusetts regio

on induced economic change in precapitalist societies abstract this essay explores a number of properties of a general growth model of induced economic change in precapitalist societies which incorporates both the insights of ester boserup and thomas malthus responses to diminishing returns include changes in work intensity and population growth some important variants of the model are also examined which focus on the transfer of production to non producers and on alternative processes by which change is induced the results are used to generate some parameters influencing the political stability of non working elites to criticize some previous less general growth models and to suggest some fruitful lines fot future empirical research on economic development in the long run

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

alleviating soil erosion pollution stock externalities alternative roles for government abstract this paper addresses two temporal externalities due to agriculture soil erosion and related pollution the possibility of decentralization of decisions the appropriate role of a resource manager and the efficiency of alternative policies are examined using traditional welfare economics concepts for a two sector model of rural urban linkage three alternative types of policies can be socially efficient but imply different involvement by government and have different knowledge requirements a pigouvian policy requires full information a bargaining solution involves government only in setting an entitlement but it may require too much knowledge by rural households in terms of understanding dynamic environmental relationships a third way is that government and rural households be co producers of environmental goods this concept assigns government the responsibility for maintaining knowledge about environmental relationships and government is a participant in a market system that determines prices for environmental related goods

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
