when is foreign aid policy credible aid dependence and conditionality the author studies foreign aid policy within a principal agent framework he shows that one reason for foreign aid s poor overall record may be a moral hazard problem that shapes the aid recipient s incentive to undertake structural reform the model s basic prediction is a two way relationship disbursements of foreign aid are guided in part by the needs of the poor anticipating this recipients have little incentive to improve the welfare of the poor preliminary econometric work shows that the data support this hypothesis in principle conditionality could partly solve this problem but only if the donor can make a binding commitment to increase disbursements in good relative to bad states without such a commitment technology aid disbursements remain guided by the needs of the poor and recipient countries maintain a low effort to reduce poverty contrary to the conventional wisdom found in the aid literature the author shows that the welfare of all parties might be improved by using tied project aid or by delegating part of the aid budget to an international agency with less aversion to poverty

bargaining over reform abstract this paper models the delay in a macroeconomic stabilization as the outcome of a bargaining game between two parties who must reach an agreement over how the stabilization cost is to be shared the paper modifies alesina and drazen s 1991 american economic review 81 1170 1189 war of attrition model by endogenizing the distribution of the stabilization costs through a bargaining game using this bargaining framework the paper analyzes the role of crises and foreign assistance in bringing about a settlement to the distributional conflict in the bargaining game a crisis that increases the welfare loss from not stabilizing the economy will lower the probability of delay in contrast foreign aid that is used to reduce the stabilization costs will further increase the delay in reaching an agreement between the two parties

kalundborg symbiosis fostering progressive innovation in environmental networks abstract many environmental networks form around specific initiatives with prescribed outcome objectives when the objectives are met the networks frequently disband technological transfer halts and the social capital built up during the initiative fragments in many cases disappearing altogether in an era of globally unsustainable economic activity encouraging progressive innovation and broadening the scale and scope of knowledge transfer is one strategy for helping to attenuate ecological damage this paper presents empirical field work which explores the kalundborg symbiosis in denmark a network of economic actors that has organically come together to implement industrial ecology principles and documents how this network has managed to foster progressive innovation the four drivers which emerged as central for fostering collaboration are i a pragmatic environmental mindset ii the existence of opportunities to explore possibilities iii mutually beneficial initiatives and iv the presence of dominant needs which stimulate a proactive search for solutions the paper also contributes to sustainable public policy and urban planning literature by considering how municipal involvement can foster progressive and sustained development within the kalundborg symbiosis

how do scholars approach the circular economy a systematic literature review abstract circular economy ce aims to overcome the take make dispose linear pattern of production and consumption proposing a circular system in which the value of products materials and resources is maintained in the economy as long as possible in recent years there has been a proliferation of scholars publications on the topic this study presents the results of a systematic literature review exploring the state of the art of academic research on ce the paper examines the ce body of literature with a systematic approach to provide an exhaustive analysis of the phenomenon with rigorous and reproducible research criteria the revisited material consists of 565 articles collected through the web of science and scopus databases and has been evaluated using specific structural dimensions to group literature into analytical categories starting from being a concept studied in connection with industrial ecology ce has slowly acquired its independent role in academic research framed mainly into environmental sustainability related studies as a result of policies implementation academic production is mainly concentrated in china and europe employing tools and methods for modelling processes and supporting decision making for ce implementation e g life cycle assessment and material flow analysis ce studies follow three main lines of action the first aims to change the social and economic dynamics at macro and administrative level the second to support firms in circular processes implementation at micro level to spread new forms of consumption and product design the third developed at meso level discusses industrial symbiosis experiences ce is associated with a variety of concepts and waste management emerges as the most relevant sub sector ce is also strongly connected with the concept of sustainability proposing ways to operationalize its implementation at the environmental and economic level while scholars only marginally consider social and institutional implications the most explored practices are those related to cleaner production aiming at reducing environmental impact and waste production along the life cycle of a product and optimizing the performance and efficiency of processes conversely studies on ce may devote greater attention to strategies for social and institutional changes able to transform the upstream process of production and consumption considering business model strategies scholars mainly focus on studying closing material loops strategy while slowing the loops which requires a radical change of consumption and production patterns is only marginally included with respect to ce implementation this study s findings highlight ce as an evolving concept that still requires development to consolidate its definition boundaries principles and associated practices

why is stabilization sometimes delayed reevaluating the regime type hypothesis existing work on the politics of stabilization has failed to find compelling evidence of a regime type effect this article reformulates and reevaluates the regime type hypothesis it is argued tha

institutional quality and capital inflows theory and evidence abstract this paper analyzes both theoretically and empirically the link between capital inflows and the quality of economic institutions to this purpose we construct a small open economy model of the soft budget constraint syndrome wherein persistently cheap funding from abroad i raises the prevalence of extractive projects and ii expands their support by the benevolent government ex post while the government may in principle limit the prevalence of extractive projects ex ante the incentives to do so is limited when foreign borrowing is cheap using a large sample of countries and controlling for reverse causality and omitted variable bias we confirm empirically that capital inflows are followed by a decline in the quality of domestic economic institutions our model and empirical analysis help explain the divergence between southern european countries spain portugal italy and greece and the rest of oecd countries since the mid 1990s

political credit cycles the case of the euro zone we study the mechanisms through which the adoption of the euro delayed rather than advanced economic reforms in the euro zone periphery and led to the deterioration of important institutions in these countries we show that the abandonment of the reform process and the institutional deterioration in turn not only reduced their growth prospects but also fed back into financial conditions prolonging the credit boom and delaying the response to the bubble when the speculative nature of the cycle was already evident we analyze empirically the interrelation between the financial boom and the reform process in greece spain ireland and portugal and by way of contrast in germany a country that did experience a reform process after the creation of the euro

industrial ecosystems as technological niches abstract in this paper we consider industrial ecology as a novel and distinct state in the evolution of production systems trajectory more specifically adopting an evolutionary institutionalist s perspective at the socio technical system level of analysis we discuss the transition towards an industrial ecology inspired industrial production system through the governance approach of strategic niche management snm towards this end the paper first develops industrial ecology as a novel state of the industrial production socio technical system paying particular attention at its technological component then it discusses in detail the transition of this system through snm and examines whether existing implementations of the industrial ecology industrial ecosystems and eco industrial parks are efforts embracing this philosophy and transition procedures we conclude by stressing the importance of adopting the technology policy and strategic niche management perspectives in eco industrial projects and we provide insights for accomplishing it in a more effective manner

do markets learn to rationally expect us interest rates an anchoring approach we propose an augmented and dynamic forecast anchoring model to examine whether a group of rational forecasters coexists with or emerges besides a group of forecasters employing heuristic rules th

waste management policies for industrial symbiosis development case studies in european countries industrial symbiosis is emerged as a self organizing business strategy among firms that are willing to cooperate to improve their economic and environmental performance the adoption of such cooperative strategies relates to increasing costs of waste management most of which are driven by policy and legislative requirements development of is depends on an enabling context of social informational technological economical and political factors the power to influence this context varies among the agents involved such as the government businesses or coordinating entities governmental intervention as manifested through policies could influence a wider range of factors and we believe this is an area which is under researched this paper aims to critically appraise the waste policy interventions from supra national to sub national levels of government a case study methodology has been applied to four european countries i e denmark the uk portugal and switzerland in which is emerged or is being fostered the findings suggest that there are commonalities in policy instruments that may have led to an is enabling context the paper concludes with lessons learnt and recommendations on shaping the policy context for is development

towards a national circular economy indicator system in china an evaluation and critical analysis abstract it is widely acknowledged that china s economic miracle has been achieved at the expense of its natural capital and environment in order to deal with this problem the circular economy ce has been chosen as a national policy for sustainable development national laws and regulations have been enacted to facilitate the implementation of ce and national ce demonstration projects have been initiated such that national benchmarking activities could be completed china is the first country to release nationally focused ce indicators so that objective and credible information on the status of ce implementation can be recognized these ce indicators are valuable metrics for policy and decision makers and can help achieve ce goals and outcomes this unique indicator system has not been communicated to international communities this paper aims to more broadly introduce this unique national ce indicator system china s ce efforts are first detailed with various provisions of the national indicator system a critical analysis of such an indicator system is presented we show that certain benefits can be gained but substantive revision is also needed due to the lack of a comprehensive set of sustainability indicators which should include social business indicators urban industrial symbiosis absolute material energy reduction and prevention oriented indicators concerns related to barriers on implementation are also presented in this paper the knowledge gained from chinese efforts on ce indicators are valuable to both developed and developing nations seeking to implement sustainable development measures within their regulatory policies

comparing the vulnerability of different coal industrial symbiosis networks under economic fluctuations we establish a vulnerability analytical framework of cisn and illustrate the impact path of economic fluctuation on cisn performance based on this we propose an improved cascading failure model with directed weighted network and design five network performance indicators i e relative value of cascading failure average path length relative value of maximal connected sub graphs network efficiency and structure entropy taking three coal eco industrial parks in china as cases we simulate and compare the impacts on cisn vulnerability i e equality based dependent based and nested based cisns of economic fluctuation the results indicate that the interaction between economic fluctuation and network structure is the key factor in determining system vulnerability concerning overall vulnerability equality based cisn is highest dependent based cisn is next and nested based cisn is lowest regarding disturbance type the changes in the five performance indicators of the three types of cisn are more intense under energy price shocks than with declining demand moreover the cascading failure scale of equality based cisn is greatest with declining demand while the other two kinds of cisn s is greatest under energy price shocks concerning disturbance intensity equality based cisn shows initial value sensitivity to economic fluctuation and nested based cisn has the strongest tolerances for economic fluctuation from the network performance perspective the performance of nested based cisn is superior to that of dependent based and equality based cisns due to longer average path length and lower network efficiency the failure diffusion trend of equality based cisn shows the curve of type s and the diffusion rate is smooth and slow contrariwise the initial diffusion rate of dependent based cisn is the highest indicating that the loss of system efficiency can somewhat improve the system s anti risk ability

can foreign aid accelerate stabilization this paper studies the effect of foreign aid on economic stabilization following alesina and drazen 1991 we model the delay in stabilizing as the result of a distributional struggle reforms are postponed because they are costly and each distributional faction hopes to reduce its share of the cost by outlasting its opponents in obstructing the required policies since the delay is used to signal each faction s strength the effect of the transfer depends on the role it plays in the release of information we show that this role depends on the timing of the transfer foreign aid decided and transferred sufficiently early into the game leads to earlier stabilization but aid decided or transferred too late is destabilizing and encourages further postponement of reforms

more than peanuts transformation towards a circular economy through a small wins governance framework governments across the world aim to accelerate the transition to a circular economy a pressing question is to what extent and how they can influence transformative change especially since a circular economy also inherently conflicts with norms underlying existing policies and regulations existing circular economy governance literature provide lists of barriers and develop targeted interventions without analyzing underlying mechanisms this paper bridges this gap by presenting a coherent conceptual framework of continuous transformative change through accumulating small wins examples from dutch circular economy transition program illustrate the arguments small wins are characterized by concrete results in terms of in depth changes of moderate importance in the long run these small wins can amplify and accumulate into transformative change through non linear mechanisms such as energizing learning by doing the logic of attraction the bandwagon effect coupling and robustness the related governance framework consists of three groups of interventions 1 setting a provocative ambition 2 identifying and appreciating small wins 3 activating mechanisms through which smalls wins can accumulate in transformative change the small wins perspective embraces ambiguity cherishes emerging change replaces linear governance models by circular systems thinking and provides insights about how small wins accumulate first observations indicate that although the small wins perspective intuitively makes sense to governance actors it clashes with the rather unrealistic expectations about governing transitions in rapid radical and top down linear ways hence governing the acceleration of a linear to a circular economy requires the transformation of the linearly organized governance system itself

understanding economic policy reform one of the eventual consequences of the global debt crisis was a wave of market oriented economic reforms this paper discusses the state of our knowledge on the political economy of this process why were inefficient and often unsustainable policies maintained for so long why are so many governments reforming now after decades of adherence to policies of an opposite kind have the reformers internalized the correct lessons from the east asian experience finally are there any helpful rules for reformers to follow in guiding their policies through complicated political terrain

the expectations hypothesis new hope or illusory support abstract recent studies of the expectations hypothesis of the term structure ehts find evidence in favor of the ehts using post 1980s us data this has been attributed to the relative macro stability of this period and greater market efficiency using a panel of forecasts for 3 month interest rates for ten countries we test separately for ehts and rational expectations assuming rational expectations holds we find support for the ehts is illusory due to an off setting time varying term premia and non rational expectations previous forecast based studies suggest biased expectations tend to reinforce the effect of a time varying term premium this change can be understood in the context of fama s 2006 argument that markets tend to underestimate future spot rates during periods of long run increases and overestimate during declines

market expectations in the uk before and after the erm crisis the british pound left the erm on 16 september 1992 after a period of turbulence uk monetary policy soon shifted to lower short interest rates and an inflation target was announced this paper uses daily option prices to estimate how the market s probability distribution of the future marks pound exchange rate and uk and german interest rates changed over the summer and autumn of 1992 the results show among other things how various policy decisions affected the market s assessment of the probabilities of realignments and lending rate cuts

testing the rationality of price forecasts new evidence from panel data this paper tests the rationality of individual price forecasts in a panel of professional forecasters here unlike in most previous studies rationality is not rejected the results here differ because 1 using individual forecasts avoids aggregation bias 2 comparison of forecasts to initial data avoids bias due to data revision 3 the professional forecasters have economic incentives to state their expectations accurately and 4 a new covariance matrix estimator consistent when forecast errors are correlated across individuals is used copyright 1990 by american economic association

new hope for the expectations hypothesis of the term structure of interest rates survey data on interest rate expectations permit separate testing of the two alternative hypotheses in traditional term structure tests that the expectations hypothesis fails and that expected future interest rates are ex post inefficient forecasts we find that the source of the spread s poor predictions of future interest rates varies with maturity at short maturities the expectations hypothesis fails at long maturities however changes in the yield curve reflect changes in expected future rates one for one an implication of the expectations hypothesis this result confirms earlier findings that long rates underreact to short rates but now it cannot be attributed to term premia if the attractiveness of an economic hypothesis is measured by the number of papers which statistically reject it the expectations theory of the term structure is a knockout most tests beginning with macaulay 1938 find no evidence supporting the expectations hypothesis 1 many cannot even reject statistically the alternative hypothesis that the spread between long and short rates contains no information about future interest rate changes 2 to make matters worse in u s postwar data future long rates tend to rise when short rates are above long rates since the expectations hypothesis would predict that long rates tend to fall the theory often does worse than even the naive model that future interest

a defense of traditional hypotheses about the term structure of interest rates expectations theories of asset returns may be interpreted either as stating that risk premia are zero or that they are constant through time under the former interpretation different versions of the expectations theory of the term structure are inconsistent with one another but i show that this does not necessarily carry over to the constant risk premium interpretation of the theory i present a general equilibrium example in which different types of risk premium are constant through time and dependent only on maturity furthermore i argue that differences among expectations theories are secondorder effects of bond yield variability i develop an approximate linearized framework for analysis of the term structure in which these differences disappear and i test its accuracy in practice using data from the crsp government bond tapes in a well known article in this journal cox ingersoll and ross cir 4 reexamine and find wanting certain hypotheses about the term structure of interest rates a striking feature of cir s re examination is that it is entirely theoretical cir show that different versions of the pure expectations theory of the term structure which traditionally were regarded as equivalent are in fact inconsistent with one another when interest rates are random furthermore in a fairly general continuous time arbitrage pricing framework when interest rates are random all versions of the theory except one are incompatible with equilibrium at first sight cir s results appear to be devastating to traditional empirical work on the term structure they suggest that researchers must specify arbitrage pricing models with a small number of state variables before proceeding to empirical work such models must restrict not only the deterministic components

striking for a bargain between two completely informed agents this paper models the wage contract negotiation procedure between a union and a firm as a sequential bargaining process in which the union must decide in each period whether or not to strike for the duration of that period we show that there exist subgame perfect equilibria in which the union engages in several periods of strikes prior to reaching a final agreement although both parties are completely rational and fully informed this has implications for other inefficient phenomena such as tariff wars debt negotiations and wars in general we characterize the set of equilibria show that strikes can occur in real time and discuss extensions of the model such as lockouts and the possibility of multiple recontracting opportunities copyright 1991 by american economic association

donor policy rules and aid effectiveness abstract the present paper examines the macroeconomic impact of aid by introducing endogenous aid allocations into a neoclassical growth framework on this basis it is shown that donor policies can have important implications for the trajectory of recipients gdp per capita depending on specific donor policy choices aid disbursements may lead to faster transitional growth stagnation or cyclical growth moreover the analysis also suggests that donor policies may be part of the reason why foreign aid is not found to be uniformly effective in raising long run productivity across recipients

when are stabilizations delayed alesina drazen revisited abstract in an influential article alesina and drazen 1991 why are stabilizations delayed american economic review 81 1170 1188 model delay of stabilization as the result of a struggle between political groups supporting reform plans with different distributional implications in this paper we show that ex ante asymmetries in the costs of delay for the groups will reduce the probability of conflict and will lead to a shorter expected delay accurate common information about the cost of delay may lead to no delay at all in an asymmetric conflict a wider divergence in the distributional implications of reform will reduce the probability of conflict but will lead to a longer expected delay we motivate the asymmetric model of delay by reference to latin american episodes of the 1980s

the history and current applications of the circular economy concept abstract the challenges of balancing industrial development environmental and human health and economic growth in china and elsewhere in the world are drivers for recent resource use and low carbon development strategies that include the application of the circular economy ce concept a central theme of the ce concept is the valuation of materials within a closed looped system with the aim to allow for natural resource use while reducing pollution or avoiding resource constraints and sustaining economic growth the objectives of this study are 1 to review the history of the ce concept to provide a context for 2 a critical examination of how it is applied currently thematic categories are used to organize the literature review results including policy instruments and approaches value chains material flows and products and technology organizational and social innovation the literature review illustrates the variability in ce project success and failure over time and by region ce successes key challenges and research gaps are identified the literature review results provide useful information for researchers as well as multi stakeholder groups who seek to define the ce concept in practical terms and to consider potential challenges and opportunities it presents when implemented

halving poverty by doubling aid is there reason for optimism this paper criticises the world bank as overly optimistic with respect to its ability to fine tune development aid and to focus it on countries with good policies rather than on countries with poor policies in order to raise its effectiveness it is shown that recipient regions showed very different patterns of aid inflows and economic growth in the past and that aid flows yielded the highest correlation to growth when their magnitudes shrank it is furthermore argued that categorising countries by quality of domestic policies is not only questionable at a given point of time especially in countries with failing governmental institutions and open borders as in many african countries it suffers also from incentive problems so that countries receiving more aid can become victims of changes in their domestic policies which are more permissive and etatist to the disadvantage of private agents the paper instead pleads for a shift to aid policies decoupled from country specifics and more oriented to fundamental beyond border problems of the well being of the poor an international endowment fund under supranational law should finance research and implementation of research findings related to common international goods as it was suggested by sachs concerning aids and tropical disease research

time variation in term premia international survey based evidence using a large previously unexplored data set of survey based interest rate forecasts that covers a broad range of countries this paper re examines the expectations hypothesis of the term structure of interest rates we find that survey based interest rate forecasts outperform not only a random walk forecast but also outperform forecasts from forward rates when using these superior survey based forecasts in a modified expectations hypothesis test the expectations hypothesis is rejected for fewer countries at lower significance levels and has greater explanatory power than when using a traditional forward rates based test we furthermore document strong time variation in the term premia which is an important reason why the traditional expectations hypothesis test is rejected so frequently this time variation seems to arise from the changing attitudes towards risk among market participants and as a compensation for the change in liquidity in the term structure finally we find that generalizing findings from earlier u s studies to other countries may lead to bias in the true economic relationships in these countries

a case study of industrial symbiosis development using a middle out approach abstract industrial symbiosis is emerged as a collective multi industrial approach to improve economic and environmental performance through the use of wastes by products as substitutes for raw materials the development of is initiatives depends on the context in which they occur characterised in terms of social economic political spatial and temporal embeddedness as a consequence the context can be influenced to become more supportive of is through a continuous interactive process combining top down governmental directives and bottom up spontaneous business initiatives a strategy to develop and enhance this process is explored in this paper and described by the authors as a middle out approach policies and policy instruments introduced by governmental agencies provide objectives and incentives to businesses the middle out approach induces the development of a strategy to create positive feedback loops among agents e g government industries that may guide their actions into setting the conditions to support is emergence this paper provides a case study that discusses a regional development of is in portugal that highlights critical factors for success in implementing is and shows that the middle out approach can also be understood as an extension and combination of previous research on context factors and planned spontaneous approaches to is development

on the expectations view of the term structure term premia and survey based expectations in this paper uk disaggregate survey data of expected future interest rates are used to test the expectations model of the term structure of interest rates at the short end of the maturity spectrum in the aggregate the expectations model is rejected and both time varying term premia and expected interest rate changes are demonstrated to be important in explaining the slope of the yield curve within the aggregate data however we demonstrate that there are some differences with respect to the views of the term structure held for example for some individuals the pure expectations model cannot be rejected

why haven t nominal rates declined the capital asset pricing model can be used to help explain the seemingly anomalous behavior of interest rates over the past several years specifically an examination of the covariances between the market returns and real unexpected rates of return on stocks bills and bonds of various durations indicates that the variance of return on longer term bonds increased appreciably between 1977 79 and 1980 81 while their correlations with stock returns rose the relative risk premiums on these bonds should have risen accordingly the calculated real risk premium on bonds of eight years duration did increase significantly between june 1979 and december 1981 it is entirely possible that this increase more than offset any decline in the long term expected inflation rate although risk alone cannot account for the increase in the real short term rate the timing of the increase suggests a possible correlation with the change in the federal reserve s operating procedures in october 1979 the puzzle of the flat nominal yield curve in the early 1980s may not be a puzzle at all

the generalized war of attrition abstract we model a war of attrition with n k firms competing for n prizes in a natural oligopoly context the k 1 lowest value firms drop out instantaneously even though each firm s value is private information to itself in a standard setting context in which every competitor suffers losses until a standard is chosen even after giving up on its own preferred alternative each firm s exit time is independent both of k and of other players actions our results explain how long it takes to form a winning coalition in politics solving the model is facilitated by the revenue equivalence theorem jel d43 d44 l13 o30

do forecast errors or term premia really make the difference between long and short rates abstract forward rates in the term structure of interest contain predictions of future spot rates plus possibly term premia realized spot rates contain predicted spot rates plus forecast errors under rational expectations forecast errors are not predictable by forecasting spot rates using publicly available information bounds on the variation of forecast errors and term premia are obtained for one month treasury bill rates one to two thirds of the variation in the difference between forward rates and realized spot rates is due to variation in term premia

new techniques to extract market expectations from financial instruments this paper is a selective survey of new or recent methods to extract information about market expectations from asset prices for monetary policy purposes traditionally interest rates and forward exchange rates have been used to extract expected means of future interest rates exchange rates and inflation more recently these methods have been refined to rely on implied forward interest rates so as to extract expected future time paths very recently methods have been designed to extract not only the means but the whole risk neutral probability distribution from a set of option prices

industrial symbiosis and the policy instruments of sustainable consumption and production abstract industrial symbioses iss and eco industrial parks eips are key concepts of industrial ecology ie the aim of iss and eips is to minimise inefficient material and energy use by utilising local by product and energy flows industrial symbioses tend to develop through spontaneous action of economic actors for gaining of economic benefit but these systems can be designed and promoted via policy instruments as well a literature review showed that national programmes for eco industrial parks can be found in different parts of the world in the action programmes and other sustainable consumption and production scp policy documents of the eu on the other hand industrial symbioses gain less recognition as a path to enhanced sustainable production in this article we consider this and also analyse how the evolution and environmental performance of an industrial symbiosis system centred on a finnish pulp and paper mill have been affected by scp policy instruments with regard to the system forming the subject of the case study and finnish industrial systems in general policy instruments have succeeded in reducing emissions but not in systematically encouraging operators toward symbiosis like activities all in all few studies exist on the overall impact of policy instruments promoting design of eco industrial parks it is not self evident that symbiosis like production systems would be sustainable in every case as the background assumptions for political promotion of eips suggest we concluded that industrial symbioses should be analysed and developed on a life cycle basis with documentation of the real environmental benefits due to efficient resource use and decreased emissions in comparison to standalone production iss can then bring eco competitiveness to companies in relation to scp tools such as environmental permits ecolabels and future product regulation based on the ecodesign directive in europe indirect encouragement of symbiosis through land use regulation and planning in such a way that material fluxes between companies are possible both in operations and in financial terms may prove effective the same holds for waste policies that encourage increased reuse of a company s waste by other enterprises

toward a research agenda for policy intervention and facilitation to enhance industrial symbiosis based on a comprehensive literature review the normative question what role should governmental policy play to facilitate the development of industrial symbiosis has received considerable attention of researchers however for several reasons the effects of governmental policy actions on industrial symbiosis are still not clear this article proposes a research agenda to clarify the mechanisms of policy intervention and facilitation of industrial symbiosis based on a comprehensive review of industrial symbiosis literature focusing on how policy is conceptualized and studied the results show that existing research lacks an explicit definition of policy and employs a static conceptualization of policy that is reinforced by comparative statics research methods we argue that a dynamic process perspective is crucial to reveal the actual mechanisms through which policy intervention and facilitation affect the evolution of industrial symbiosis building on this view industrial symbiosis research is connected with insights from policy sciences and the case of policy translation of circular economy and eco industrial park in china is investigated in order to illustrate that policy is at heart a dynamic process we conclude with a research agenda proposing that the key to reveal the mechanisms is to identify the sequence of events connecting policy process and industrial symbiosis practices

blue chip rationality tests this paper tests the rationality of forecasts made by individuals who contribute to the blue chip consensus forecasting service and tries by means of a questionnaire on forecasting methods to establish why some forecasters appear more rational than others tests based on consensus forecasts prove unreliable as guides to the number of individuals who produce rational forecasts individual forecasts are more likely to be rational if they are based on a mainstream economic theory and incorporate a substantial element of judgment copyright 1991 by ohio state university press

clientelism and aid abstract using a model of probabilistic voting we analyze the impact of aid on the political equilibrium in the recipient country or region we consider politicians with mixed motives they are interested in promoting social welfare but also value the benefit of holding office we label as clientelistic the politician who most values the benefit of being in power we find that the impact of aid on the political equilibrium and therefore on the quality of policy in the recipient country using utilitarian social welfare as a benchmark ultimately depends on the value of the elasticity of the marginal utility of consumption when elasticity is low the expected policy outcome gets further away from the socially desirable policy set this substitution of policy quality for aid can help to explain the poor performance of aid in improving policy perhaps more surprising is the opposite case which arises for high values of elasticity of marginal utility an increase in aid tilts the equilibrium policy towards the welfare maximizing policy set

do corrupt governments receive less foreign aid critics of foreign aid programs argue that these funds often support corrupt governments and inefficient bureaucracies supporters argue that foreign aid can be used to reward good governments this paper documents that there is no evidence that less corrupt governments receive more foreign aid on the contrary according to some measures of corruption more corrupt governments receive more aid also we could not find any evidence that an increase in foreign aid reduces corruption in summary the answer to the question posed in the title is no

debt stabilization with a deadline abstract this paper presents an extension of the alesina and drazen 1991 american economic review 81 1170 1188 war of attrition model extended by including an exogenous deadline beyond which a punishment namely a penalty is exacted from all players in case of no agreement i solve for this game and establish that the higher the penalty is the higher the probability of stabilizing the debt on time will be i also show that there is a period of complete inertia right before the deadline no group of agents wants to concede just before this date the length of this period of total inertia is increasing in the penalty

strategic delay in bargaining this paper analyses a bargaining model with incomplete information in which the time between offers is an endogenous strategic variable we find equilibria involving a delay to agreement that is due to the use of strategic time delay by bargainers to signal their relative strength under some specifications of the parameters delay is present in the unique sequential equilibrium whose beliefs satisfy one intuitive restriction this delay does not vanish as the minimal time between offers becomes small
