governance of competitive transmission investment in weak institutional systems despite progress in economic analysis in recent years transmission investment governance still poses policy design challenges in competitive electricity systems the degree of regulatory intervention in allocating investment costs is a central issue scholars tend to agree that centralized solutions are almost inevitable mainly due to free riding and coordination problems in systems with weak institutional endowments and pressures of distributive politics however there is an increased likelihood of regulators acting opportunistically or imposing arbitrary changes to the cost allocation rules which makes centralized solutions less desirable we provide some examples from argentina el salvador and peru and suggest that a two tier governance scheme composed of a self governing forum of transmission stakeholders with regulation as a subsidiary measure may be a more adequate design to restraint undue government interference the expected outcome is twofold a better match with users preferences and a restraint to government opportunism and arbitrariness measuring the robustness of this scheme in minimizing the risks for either too much or too little investment will certainly require further research

panel discussion price stability how should long term monetary policy be determined these comments address the question of monetary strategy as distinct from monetary tactics they are not directed at the question of what monetary policy is appropriate at the present time or of how monetary policy should be determined at any specific point as a function of prevailing conditions instead the issue i take is one that has been of increasing interest to economists in recent years what should be the long terrn objectives of the monetary authority increased interest in this issue as opposed to the issue of fine tuning the economy reflects the general intellectual consensus that has emerged on two points first what the monetary authority surely can control in the long run is the growth rate of nominal income second issues of dynamic consistency and commitment are crucial to the design of appropriate monetary policies beyond its recognition of these points my view is that most of what the academic economics community has had to say on the issue of long run monetary strategy has been tangential at best and i fear that many of the papers at this conference have not done much to improve the situation i wish to advance four propositions about monetary policy and to discuss their implications first an optimal tax theory has little or nothing to do with sensible inflation policy second positive rates of inflation are almost certainly desirable third to an important extent institutions do the work of rules and monetary rules should be avoided instead institutions should be drafted to solve time inconsistency problems fourth h j res 409 the proposed zero inflation amendment is a good idea if it is not taken too seriously or too literally but is instead viewed as a device for strengthening the independence of the federal reserve system my first proposition is that the connection between optimal tax theory and infla

whether crop diversification is a desired strategy for agricultural growth in bangladesh abstract this study aimed at examining the merit of crop diversification as a strategy for agricultural growth in bangladesh specifically the existence of economies of diversification scale economies and diversification efficiencies at the farm level were examined using a stochastic input distance function approach the results reveal strong evidence of diversification economies amongst most crop enterprises except the combination of modern rice and modern wheat enterprises ray economies of scale exist in bangladeshi cropping system also significant are efficiency gains made from diversification among cropping enterprises the key policy implication is that crop diversification should be a desired strategy for agricultural growth in bangladesh development of the rural infrastructure is also essential as this will not only improve technical efficiency but may also synergistically promote crop diversification by opening up opportunities for technology diffusion marketing storage and resource supplies

price level targeting vs inflation targeting a free lunch price level targeting without base drift and inflation targeting with base drift are compared under commitment and discretion with persistence in unemployment price level targeting is often said to imply more short run inflation variability and thereby more employment variability than inflation targeting counter to this conventional wisdom under discretion a price level target results in lower inflation variability than an inflation target if unemployment is at least moderately persistent a price level target also eliminates the inflation bias under discretion and as is well known reduces long term price variability society may be better off assigning a price level target to the central bank even if its preferences correspond to inflation targeting a price level target thus appears to have more advantages than commonly acknowledged

alternative views of the money transmission mechanism what difference do they make for monetary policy this paper examines how alternative views of the monetary transmission mechanism affect the choice of a monetary policy rule the main finding is that many different structural models indicate that the same simple monetary policy rule one in which the central bank s target short term interest rate reacts to inflation and to real output would perform well such rules work well even in models where the monetary transmission mechanism has a relatively strong exchange rate channel the models differ however in their implications for more complex monetary rules prepared for the oxford review of economic policy this paper is an updated revised and shortened version of an earlier paper entitled the monetary transmission mechanism and the evaluation of monetary policy rules presented at the central bank of chile in september 20 21 1999 i am grateful to david vines for very helpful comments

inflation output variance trade offs and optimal monetary policy the author estimates the inflation output gap variance trade off faced by monetary policymakers in the united states for policymakers who care about deviations of inflation around target and output around potential the estimated trade off represents the optimal policy frontier given the structure of the economy policymakers can do no better than to attain weighted variances of inflation and output that lie on the frontier the author finds that the variance trade off becomes quite severe when the standard deviation of inflation or output drops much below 2 percent this suggests that approximately balanced responses to policy goals are consistent with reasonable preferences over inflation and output variability copyright 1997 by ohio state university press

extending the bargaining power model explaining bargaining outcomes among nations mnes and ngos participants in international bargaining include different types nation states mnes ngos and multilateral organizations and different numbers of these actors our theoretical contribution is to extend the bargaining power paradigm with a framework that models bargaining in this complex environment as a network the configuration of supports and constraints among all participating actors in the bargaining environment is captured in the structure of the network antecedents of an actor s bargaining influence in the network include the actor s basis of power network position bargaining outcome preferences and motivation to influence bargaining the network bargaining power nbp model uses network theory to build upon and integrate insights from previous literature in a way that allows us to simultaneously apply these different insights to explain bargaining outcomes these insights include effects of coalitions strategies of less powerful actors leveraging more powerful allies integration of international and domestic politics and applicability to mne related issues beyond fdi finally we illustrate nbp in a scenario of privatized utilities in the dominican republic in which the bargaining power outcome predicted by nbp differs from that of the canonical bargaining power perspective

risk premium shocks and the zero bound on nominal interest rates there appears to be a disconnect between the importance of the zero bound on nominal interest rates in the real world and predictions from quantitative dsge models recent economic events have reinforced the relevance of the zero bound for monetary policy whereas quantitative models suggest that the zero bound does not constrain optimal monetary policy

dealing with monetary paralysis at the zero bound recently the key constraint for central banks is the zero lower bound on nominal interest rates central banks fear that if they push short term policy interest rates too deeply negative there will be a massive flight into paper currency this paper asks whether in a world where paper currency is becoming increasingly vestigial outside small transactions at least in the legal tax compliant economy there might be relatively simple ways to finesse the zero bound without affecting how most ordinary people live surprisingly this question gets little attention compared to the massive number of articles that take the zero bound as given and look for out of the box solutions for dealing with it in an inversion of the old joke it is a bit as if the economics literature has insisted on positing assume we don t have a can opener without considering the possibility that we might be able to devise one it makes sense not to wait until the next financial crisis to develop plans fundamentally there is no practical obstacle to paying negative or positive interest rates on electronic currency and as we shall see effective negative rate policy does not require eliminating paper currency

agricultural diversification and integrated pest management in bangladesh we study factors associated with a shift toward diversified high valued vegetable crops and the incentives associated with the use of ipm methods for vegetable producers in bangladesh the primary objective is to measure how ipm technologies affect the crop and technology choices of low income rice farmers a three season household optimisation model is used to study crop and technology choice under price and yield uncertainty the model is parameterised using data from vegetable farms and experimental ipm trials conducted in bangladesh simulation results show that access to ipm technology and ipm availability combined with access to credit increase household welfare and lead to higher rates of vegetable adoption off farm employment opportunities work against vegetable cultivation and ipm use by risk averse farmers implications for policy and extension efforts are highlighted

farmer training in off season vegetables effects on income and pesticide use in bangladesh the cultivation of crops outside the regular cropping calendar when supply is low and prices are high can give farmers better profits and consumers more choice however off season production may increase pesticide risk if crops are more affected by pests and diseases and farmers do not handle pesticides correctly this study quantified the effect of training in off season tomato production on the income and pesticide use of smallholder vegetable farmers in southwestern bangladesh the study uses farm level data from 94 trained and 151 non trained farm households and applies propensity score matching and inverse probability weighting to correct for selection bias for the average smallholder vegetable farmer training increased net household income by about 48 we found that 31 of the trained farm households who had initially adopted the technology continued its use in the second year but farm households who discontinued using the technology also experienced significant income gains from the training there was a significant increase in pesticide use 56 and although there was an improvement in pesticide handling practices trained farmers may have been more exposed to pesticide health risk the policy implication is that while off season vegetable production can create dramatic income improvements it is important to emphasize safe and sustainable pest management methods as part of policies promoting it

the impact of improved maize varieties on poverty in mexico a propensity score matching approach summary this study examines the adoption of improved maize germplasm in oaxaca and chiapas in mexico it employs a propensity score matching approach to analyze the impact of the adoption of improved maize varieties on household income and poverty reduction using cross sectional data of 325 farmers from the two regions the findings reveal a robust positive and significant impact of improved maize variety adoption on farm household welfare measured by per capita expenditure and poverty reduction specifically the empirical results suggest that adoption of improved maize varieties helped raise household per capita expenditure by an average of 136 173 mexican pesos thereby reducing their probability of falling below the poverty line by roughly 19 31

monetary policy trade offs and the correlation between nominal interest rates and real output the authors present a structural model of the u s economy that combines their price contracting specification with a term structure relationship an aggregate demand curve and a monetary policy reaction function the model matches important features of postwar data well and provides a structural explanation of the correlation between real output and the short term nominal rate of interest the authors perform a battery of monetary policy experiments that show that as viewed through the lens of this model monetary policy has struck a good balance recently among competing monetary policy objectives copyright 1995 by american economic association

agricultural pesticides and land use intensification in high middle and low income countries abstract we study levels and trends in agricultural pesticide use for a large cross section of countries using fao data for the period 1990 2009 our analysis shows that a 1 increase in crop output per hectare is associated with a 1 8 increase in pesticide use per hectare but that the growth in intensity of pesticide use levels off as countries reach a higher level of economic development however very few high income countries have managed to significantly reduce the level of intensity of their pesticide use because decreases in insecticide use at higher income levels are largely offset by increases in herbicide and fungicide use the results also show very rapid growth in the intensity of pesticide use for several middle income countries such as brazil mexico uruguay cameroon malaysia and thailand complementing our analysis with data from the rotterdam convention on prior informed consent pic we show that hazardous pesticides covered in the pic procedure are more weakly regulated in lower than in higher income countries we discuss the policy challenges facing developing countries with a rapid growth in pesticide use and recommend a four pronged strategy including an environmental tax on pesticides with revenues allocated to long term investments in awareness building the development of integrated crop management methods and the setting of food safety standards the interactions between these measures should help contribute to the effectiveness of the overall strategy package

the politics of regulation in the turkish electricity market abstract turkey began reforming the electricity market in 2001 the regulatory reform aimed to liberalize the market however the institutional and political structure was not ready for creating an efficiently working competition the independent regulator did not have both experience and will to direct the industry to a more competitive environment currently the reform has slowed down and political preferences drive the industry this paper studies the reasons for the slowdown in the reform efforts by focusing on the relationships between the government judiciary and the independent regulator we conclude that strategic behaviors of players in the market including the judiciary the government and the regulator have made the introduction of competition to the market more costly

deregulating with no regulator is the german electricity transmission regime institutionally correct abstract from 1998 to 2005 the german transmission grid has been put under a self regulated arrangement it seems hard to believe that transmission lines can be opened to third party access only with a negotiated access regime and no regulator supervision it seems contradictory with the notion of ex post contractual hazards promoted by v goldberg and o williamson if a weak institutional arrangement is implemented one might assume that it has to be harmful to network and market access if it is not to be inefficient why and how could it work when looking at rules and prices for accessing the transmission network and the corresponding wholesale markets in germany the club arrangement for transmission opening does not appear so harmful accordingly we have to reconsider the ex ante and ex post institutional mechanism of such a club arrangement ex ante we first reconsider skills and strengths of industrial consumers and german business associations in defining and assessing rules of transmission access we underline that incomplete vertical and horizontal integration of german electricity companies impeded extensive cartel collusion ex post we first look at a strong competition authority backing then we discover that ex ante and ex post dimensions are much more mixed and reinforced in an open cumulative pro competition process framed by the competition authority

the robustness and efficiency of monetary policy rules as guidelines for interest rate setting by the european central bank abstract this paper examines the implications of recent research on monetary policy rules for practical monetary policy making with special emphasis on strategies for setting interest rates by the european central bank ecb the paper draws on recent research and new simulations of a large open economy model to assess the efficiency of a simple benchmark rule in comparison with other proposed rules further it stresses new results on the robustness of monetary policy rules in which each rule that is optimal or good according to one model or researcher is tested for robustness by other researchers using different models because of the large increase in the number of economists focussing on econometric evaluation of monetary policy rules for the interest rate instrument and because of the parallel increase in the variety of models being developed for this purpose much more evidence is becoming available on the robustness of simple monetary policy rules for the interest rate than ever before

estimates of the variance of u s inflation based upon the arch model it is generally agreed that the unpredictability of future inflation is a major component of the welfare loss associated with inflation perfectly predicted inflation might induce some costs through institutional rigidities governmental interference and transaction costs but in the long run these should be rather minimal as these institutions adopt various forms of indexing when inflation is unpredictable risk averse economic agents will incur a loss even if prices and quantities are perfectly flexible in all markets inflation is a measure of the relative price of goods today and goods tomorrow thus uncertainty in tomorrow s price impairs the efficiency of today s allocation decisions friedman in his nobel lecture 8 argues convincingly that higher variability of inflation would lead to decreased output ceteris paribus he then conjectures that higher rates of inflation are generally associated with higher variability of inflation and presumably greater uncertainty about future rates if this is true then higher rates of inflation would also be associated with low levels of output which implies a positively sloped phillips curve this paper uses a new statistical technique arch to estimate the conditional mean and variance of inflation from u s time series data the main finding is that the variance of inflation in the seventies was only slightly greater than in the sixties

adaptability of competitive electricity reforms a modular analysis abstract among the competitive electricity reforms that have been implemented in europe and the us for the last 18 years none has survived over several years without major changes their changing nature raises the question of their adaptability two characteristics of reforms play a key role on their adaptation properties firstly they are modular objects in the sense of baldwin c 2008 where do transactions come from modularity transactions and the boundaries of firms industrial and corporate change 17 1 155 195 secondly they are produced in an institutional process which leads to incomplete rules and designs pistor k xu c 2003 incomplete law international law and politics 35 931 1013 we propose a typology of adaptations based on the framework proposed by williamson o e 1991 comparative economic organization the analysis of discrete structural alternatives administrative science quarterly 36 2 269 296 for contracts 1 in case of small disturbances adaptations are realized quasi automatically by autonomous decisions of the institutions governing the implementation of reforms 2 in case of middle range disturbances adaption is made by coasian bargaining 3 finally in case of strong disturbances or when bargaining is not feasible the adaptation of reforms is in the hands of legislative and executive institutions north d c 2005 le processus du developpement economique editions d organisation these institutions can reform the reforms joskow p l 2006 introduction to electricity sector liberalization lessons learned from cross country studies in sioshansi f p ed electricity market reform an international perspective elsevier amsterdam pp 1 32 hogan w w 2002 electricity market restructuring reforms of reforms journal of regulatory economics 21 103 132 the role of these types of adaptations in each electricity reform is a consequence of the allocation of rights to the regulator to stakeholders and to legislative and executive institutions

the impact of a food security program on household food consumption in northwestern ethiopia a matching estimator approach abstract with the financial support from various development partners ethiopia has designed and implemented several programs to improve household food security yet food insecurity is still a major challenge to several millions of people in the country and it is questionable whether the different food security programs implemented over the past years have been successful using a propensity score matching method to control for pre intervention differences this study examined the impact on household food calorie intake of an integrated food security program ifsp which had been implemented in northwestern ethiopia by two non governmental organizations as a case study the estimated results provide evidence that ifsp has a positive and statistically significant effect on food calorie intake in particular ifsp has raised physical food calorie intake by 30 among the beneficiary households however we also found that ifsp has differential impact depending on family size landownership and gender of head of household overall the paper provides evidence that supporting integrated food security programs is important to improve food security in rural areas

institutions and commitment the thrust of this paper is that to understand the roles institutions play in society a deep analysis of opportunism and its implications is necessary for that purpose a transactions costs cum positive political theory approach is developed with a focus on the role of institutions and their implications for regulatory commitment a major issue is restraining political opportunism countries that have succeeded in developing a healthy private sector are those that have developed institutions that restrain governmental decision making but such restraining is itself a political choice countries with electoral and legislative systems that bring about decentralized government have stronger chances of developing equilibria where government discretion is restrained copyright 1996 by oxford university press
