the fisher hypothesis and the forecastability and persistence of inflation abstract for the period 1860 to 1939 the simple correlation of the u s commercial paper rate with the contemporaneous inflation rate is 0 17 the corresponding correlation for the period 1950 to 1979 is 0 71 this paper attributes this apparent change in the fisher relation to differences in the stochastic process of inflation rather than a change in any structural relationship between interest rates and expected inflation contrary to recent claims in the literature there is little evidence of inflation non neutrality in data from the pre world war i period

bureaucratic theory and the choice of central bank goals economists have frequently asserted that central bank priorities among economic goals have not been appropriate to the public s desires for example one interpretation of the results of reuber s pioneering study of central bank preferences was that the bank of canada s reactions reflect the placing of a very heavy implicit weight on price stability compared with higher employment presumably based on a judgement about the relative economic costs of more unemployment and more price inflation the evidence examined on the relative economic costs of price inflation and unemployment suggests that the economic costs of inflation are not as high relative to the costs of unemployment as the reactions and statements of the authorities have implied reuber p 132 1

designing supply contracts contract type and information asymmetry this paper studies the value to a supplier of obtaining better information about a buyer s cost structure and of being able to offer more general contracts we use the bilateral monopoly setting to analyze six scenarios three increasingly general contracts wholesale pricing schemes two part linear schemes and twopart nonlinear schemes each under full and incomplete information about the buyer s cost structure we allow both sides to refuse to trade by explicitly including reservation profit levels for both for the supplier this is implemented through a cutoff policy we derive the supplier s optimal contracts and profits for all six scenarios and examine the value of information and of more general contracts our key findings are as follows first the value of information is higher under two part contracts second the value of offering two part contracts is higher under full information and third the proportion of buyers the supplier will choose to exclude can be substantial

sufficiency or efficiency to achieve lower resource consumption and emissions the role of the rebound effect a frequent criticism of eco efficiency strategies is that an increase in efficiency can be offset by the rebound effect sufficiency is discussed as a new strategy involving self imposed restriction of consumption but can also be subject to the rebound effect we show that the range of possible secondary effects of efficiency and sufficiency strategies goes beyond the rebound effect the rebound effect can indeed also be linked to eco sufficiency strategies but there are further secondary effects of both eco efficiency and eco sufficiency strategies such as double dividend effects we develop an eco efficiency sufficiency matrix to logically order eco efficiency and sufficiency measures to attain lower resource consumption and emissions

optimal seigniorage the gold standard and central bank financing this paper extends the theory of optimal seigniorage to allow for money production costs an important implication is tha t high money production costs along with a requirement that the monet ary branch of government self finance its operation severs the connecti on between the tax rate on output and the tax rate on money using u s data the authors find that tax rates on output and money move together only during periods when the government controls both tax rates and there is a close correspondence between revenue produced b y the monetary authority and revenue transferred to the treasury copyright 1993 by ohio state university press

the effects of a free repair warranty on the discrete time periodic replacement policy abstract this paper presents the effects of a free repair warranty on a periodic replacement policy with a discrete time process considering a repairable product that should be operational at the time over an indefinitely long operation cycle n n 1 2 under the discrete time periodic replacement policy a product is preventively replaced at pre specified operation cycles n 2 n 3 n n 1 2 when the product fails a minimal repair is performed at the time of failure and the failure rate is not disturbed by each repair the cost models from the customers perspectives are developed for both warranted and non warranted products the corresponding optimal replacement period n is derived such that the long run expected cost rate is minimized under the assumption of the discrete time increasing failure rate the existence and uniqueness of the optimal replacement period are shown and the impact of a free repair warranty on the optimal periodic replacement policies is investigated analytically the optimal n for a warranted product should be adjusted toward the end of the warranty period finally numerical examples are demonstrated for the optimal policy illustration and verification the observations from the numerical results provide valuable information for a buyer user to adjust the optimal periodic replacement policy if a product is operating in discrete time under a free repair warranty

inflationary bias of the federal reserve system a bureaucratic perspective abstract the federal reserve system does not receive a budget from congress but instead finances its operation from interest payments on its government security portfolio this peculiar financing arrangement provides the foundation for a bureaucratic model of federal reserve official behavior the empirical section tests the bureaucratic model by analysing the fed s expenditure record since 1947 and its policy actions during periods of constitutional revision

meat consumption and production analysis of efficiency sufficiency and consistency of global trends abstract the sustainability challenges that the food system is facing are ever increasing the traditional approach to monitoring these changes considers economic societal and environmental sustainability a strong case has been made however that a fourth dimension ethical should also be considered conventionally two main strategies have been used to assess the improvements in sustainability efficiency and sufficiency efficiency is usually linked with technological improvements and sufficiency is connected with a reduction in production or consumption we introduce a third strategy to the analysis namely consistency that is related mainly to the ethical dimension of sustainability trends of the indicators related to the three strategies are calculated on both a global and regional scale from 1962 to 2009 efficiency measured as land requirement for animal products has increased by about 13 percent globally sufficiency measured as the amount of meat consumed has declined by 91 percent and consistency measured as the number of animals slaughtered has declined by 264 percent in addition convergence analysis emphasizes that industrialized and developing countries are moving towards similar patterns of animal products consumption such results suggest that measures should be taken to develop a food system that is not only efficient but also ethically just

time consistent collection of optimal seigniorage a unifying framework this paper reviews the existing literature on the time consistency problem of seigniorage collection when monetary policy is determined by optimal taxation considerations it develops a unifying accounting framework and suggests a general measure for seigniorage which encompasses the standard measures employed in the literature in addition the ex ante optimal solution to the optimal taxation problem is derived and interpreted in relation to the ramsey principle we show that the different recommendations of the public finance literature i e the friedman rule of optimal deflation moderately positive inflation and seigniorage maximizing inflation are specific solutions to the optimal taxation problem the paper continues with a formal illustration of the time consistency problem of the ex ante optimal policy and the characterization of the time consistent solution under discretion as possible solutions to the time consistency problem we consider reputational forces institutional reforms that establish central bank independence and specific ways of asset and debt management in particular it is formally shown that a modified version of the asset and debt management scheme suggested by persson persson and svensson is not only necessary but also sufficient for optimality although this did not hold in their model

some two echelon supply chain games improving from deterministic symmetric information to stochastic asymmetric information models abstract many supply chain and inventory models use the following two echelon symmetric information and deterministic gaming structure a manufacturer wholesales a product to a retailer who in turn retails it to the consumer the retail market demand varies with the retail price according to a deterministic demand function that is known to both the manufacturer and the retailer it is then assumed that the players the manufacturer and the retailer arrive at their pricing and batch size decisions through a stackelberg game or a fixed markup percentage game the first part of this paper reveals many implausible effects of demand curve forms on the behavior of these gaming models however we do not merely conclude that two echelon gaming results obtained via assuming one convenient demand curve form can often become invalid under other demand curve forms more importantly we argue in the second part of the paper that the various implausible effects revealed here suggest a different but more fundamental conclusion the assumed non cooperative games are themselves flawed because gaming is meaningless and logically circular in a deterministic and symmetrical information system we then present an introductory illustration on how the introduction of stochasticity and information a symmetry leads to more plausible two echelon supply chain gaming models together the two parts demonstrate the necessity and practicality of using a stochastic and asymmetric information instead of the prevalent deterministic symmetric information approach in many supply chain models

strategic commitments for an optimal capacity decision under asymmetric forecast information we study the important problem of how to assure credible forecast information sharing between a supplier and a manufacturer the supplier is responsible for acquiring the necessary capacity before receiving an order from the manufacturer who possesses private forecast information for her end product we address how different contracts affect the supplier s capacity decision and hence the profitability of the supplier and the manufacturer we fully develop two contracts and provide explicit formulae to enable credible forecast information sharing the first is a nonlinear capacity reservation contract under which the manufacturer agrees to pay a fee to reserve capacity the second is an advance purchase contract under which the manufacturer is induced to place a firm order before the supplier secures the component capacity used to build the end product these contracts serve a strategic role in information sharing the capacity reservation contract enables the supplier to detect the manufacturer s private forecast information while the advance purchase contract enables the manufacturer to signal her forecast information we show that channel coordination is possible even under asymmetric forecast information by combining the advance purchase contract with an appropriate payback agreement through our structural and numerical results we also show that the degree of forecast information asymmetry and the risk adjusted profit margin are two important drivers that determine supply chain efficiency and which contract to adopt

the benefits of central bank s political independence abstract we consider a two tier model of monetary policy where the central banker is both subject to the explicit influence of elected political principals through contracts and the implicit influence of interest groups willing to capture monetary policy we analyze the impact of granting independence to the central banker on the scope for capture and the agency costs of delegating the monetary policy to a central banker political independence increases those agency costs but significantly stabilizes the politically induced fluctuations of inflation and improves ex ante social welfare

strong sustainable consumption governance precondition for a degrowth path this paper aims to link two debates and literatures at the cutting edge of sustainable development research and governance sustainable consumption and degrowth interestingly these literatures have only recently started to exchange and integrate insights despite their similar interest in the fundamental systemic challenges to sustainable development the paper argues that this lack of connection is due to a predominance of perspectives in sustainable consumption governance that focus almost exclusively on questions of efficiency gains this weak sustainable consumption governance however is not able to address the challenges to sustainable development arising from overconsumption in general or the rebound effect and distributive issues in particular in contrast a strong sustainable consumption perspective provides a basis for a promising inquiry into the linkages between consumption and sustainable development as well as a fruitful exchange with degrowth specifically it allows the delineation of relevant insights on the role of values in governance obstacles to political reform and promising political strategies for the degrowth debate and literature

preliminary evidence on the determinants of federal reserve open market operations in the absence of a fixed policy rule the federal reserve bank fed has significant discretion in setting monetary policy the existence of professional fedwatchers attests to the fact that fed policy actions are difficult to interpret recent literature has focused on the motivations behind fed policy making and the need for secrecy and ambiguity we investigate one aspect of fed behavior the propensity of the fed to buy and sell government securities beyond that required to implement stated policies milton friedman 1982 26 called attention to this issue when he wrote

three perspectives on sustainable food security efficiency demand restraint food system transformation what role for life cycle assessment achieving food system sustainability is a global priority but there are different views on how it might be achieved broadly three perspectives are emerging defined here as efficiency oriented demand restraint and food system transformation these reflect different conceptualisations on what is practically achievable and what is desirable underpinned by different values and ideologies about the role of technology our relationship with nature and fundamentally what is meant by a good life this paper describes these emerging perspectives and explores their underlying values highlights lca s role in shaping these perspectives and considers how lca could be oriented to clarify thinking and advance policy relevant knowledge it argues that more work is needed to understand the values underlying different approaches to the food sustainability problem this can shed light on why stakeholders disagree where there are genuine misunderstandings and where common ground is possible and ways forward agreed

the bond price support program as a change in policy regimes evidence from the term structure of interest rates recently mankiw miron and weil 1987 argued that a change in policy regimes generally affects the public s expectations of future interest rates to illustrate this influence they compare the operation of the gold standard with the post gold standard regime in the united states they find that nominal short term interest rates were mean reverting before 1914 but became nonstationary after the creation of the federal reserve system we extend mankiw miron and weil s analysis by noting that the period from 1914 to the present cannot be characterized as one uninterrupted episode of policy discretion the united states temporarily abandoned discretion for a rule in the 1940s the fed and treasury agreed in april 1942 that the fed would adjust federal reserve credit in a manner that would produce relatively low market rates on longterm securities in particular the fed committed itself to support twenty year government bond prices at a level consistent with a 2 5 percent interest rate ceiling we investigate the possibility that the bond price support program of the 1940s conditioned the behavior of short term interest rates in a predictable way according to the expectation theory of the term structure a binding long term interest rate ceiling implies that an increase in the current short rate must cause the sum of the innovation and the change in future expected rates to be zero otherwise the long rate rises above the ceiling and the public perceives a violation of the bond rate commitment placing a binding ceiling on long term interest rates tends to make short term interest rates mean reverting

average marginal tax rates from social security and the individual income tax we extend previous estimates of the average marginal tax rate from the federal individual income tax to include social security our computations consider the tax rates on employers employees and the self employed the income that accrues to persons with earnings below the ceiling and the effective deductibility of employers social security contributions from workers taxable income the next effect of social security on the average marginal tax rate is below 02 until 1966 but then rises to 03 in 1968 04 in 1973 05 in 1974 06 in 1979 and 07 in 1982 this abstract was borrowed from another version of this item

economic growth sustainable development and food consumption evidence across different income groups of countries abstract considering that high population and income growths will lead the coming decades an increase in global food demand is expected livestock products such as meat are closely related to this trend but also associated with impacts on the environment and public health from land and water depletion to greenhouse gases emissions and higher risks of non communicable diseases this trend raises doubts about the sustainability of the food industry and thus a solution is needed for the problem how to feed the world population without compromising present and future generations the literature suggests that meat consumption should be reduced for the sake of the environment and global population however without considering the effects that such reduction would have on the economy inspired by these facts this paper empirically analyses the interactions between food consumption economic growth and sustainable development measured by the index of sustainable economic welfare more specifically the paper assesses the effect that food consumption has on the economy the econometric analysis applies the autoregressive distributed lag model for 77 countries further distinguished by their income group from 1995 to 2013 the findings support that meat consumption has different impacts on economic growth and sustainable development considering different income groups however there is an evident dilemma between economic growth and sustainable development since meat consumption has contradictory effects on each thus it is crucial to understand how to promote sustainability i e reducing the environmental externalities and chronic health diseases without compromising economic growth

technological progress and sustainable development what about the rebound effect abstract sustainability concepts that rest on the idea of resource or energy efficiency improvements due to technological progress tend to overestimate the potential saving effects because they frequently ignore the behavioral responses evoked by technological improvements efficiency improvements also affect the demand for resources and energy and often an increase in efficiency by 1 will cause a reduction in resource use that is far below 1 or sometimes it can even cause an increase in resource use this phenomenon is commonly labeled the rebound effect which is well known among energy economists but never attracted much attention in ecological economics the paper starts with the traditional neoclassical analysis of the rebound effect in a partial equilibrium framework that concentrates on the demand of one particular energy service such as mobility or room temperature it also provides an overview of some of the main empirical studies based on this model that mostly confirm the existence of the rebound effect but are controversial about its actual importance however we have to go beyond the neoclassical single service model in order to take care of the variety of possible feedback affecting energy use the paper presents two important expansions of the single service model in order to show the potential relevance of the rebound effect to ecological economics first it is shown that in a multi services model it proves to be difficult to make general statements about the relevance of the rebound effect in this case the overall effect of an increase in energy efficiency on total energy use depends on the on the assumptions about the substitutability between the services considered and the direction of the income effect second the paper also tries to take care of the fact that changes in resource use or energy use are frequently just side effects of other forms of technological progress especially technological change of a time saving nature can have a large influence on energy use as many time saving devices for example faster modes of transport require an increase in energy consumption that is frequently reinforced by a rebound effect with respect to time this effect will be especially strong when wages are high and at the same time energy prices are low as is currently the case in most industrialized countries consequently the paper also provides a strong argument for the introduction of energy taxes

eco efficiency as abandonment of nature abstract the paper argues that eco efficiency is fundamentally disruptive when promoted as a universal prescription for environmental policy eco efficiency runs against the cognitive and institutional bases of sustainable human environmental interaction at the cognitive level eco efficiency assumes that an individual s concern for the environment can be decoupled from his or her material dependency on ecosystem services at the collective level eco efficiency builds upon decoupling environmental governance from the local socio economic and cultural context the assumptions are not well supported by empirical work on systems of human environmental interaction which stresses the importance of material connections to maintaining environmental concerns the criterion for adopting eco efficiency should be the extent to which it promotes the recoupling of human perception of environmental issues with human action on the environment and the concomitant recoupling of collective local organization with locally crafted ecosystem management

seigniorage and tax smoothing in the united states 1914 1986 abstract when monetary and fiscal authorities cooperate to minimize the distortionary costs of financing an exogenous stream of government expenditures barro s tax smoothing model implies a long run relationship between tax revenues and inflation previous empirical tests of this relationship are reinterpreted in light of recent work on cointegration and are shown to hold only when stochastic temporal variation in the excess burden of taxes and seigniorage is transitory in nature a new test that holds in the presence of nonstationary disturbances is developed and applied annual u s data from the period 1914 to 1986 reject the revenue smoothing hypothesis

policy rules inflationary bias and cyclical stability statutory policy rules such as a k percent rule for money growth can restrain officials from pursuing their own welfare at the expense of the public good toma 1982 and barro and gordon 1983 among others have presented theoretical models showing how macroeconomic policymakers who pursue their own interests can produce policies that are biased toward too much inflation strict rules are a possible remedy to this problem yet while strict policy rules may reduce inflationary bias they also limit the flexibility of officials to respond to random shocks researchers such as canzoneri 1985 have shown that this can be an important limitation if officials possess information advantages that permit policy to modify economic disturbances effectively if the public dislikes variations in real output this loss of flexible stabilization may offset any gain from a reduction in inflationary bias there is then a potential trade off between reducing inflationary bias and cyclical stability yet to date none of the dimensions of this trade off has been documented evidence of an inflationary bias has been scarce in part because it requires identification of the socially preferred inflation rate similarly the extensive research on electorate concerns with real output has focused on the income level rather than its variance moreover since this research has not been cast in a framework that permits voters to recognize the potential inflationary cost of stabilizing output the validity of these findings is open to question indeed recent work by lucas 1987 suggests that citizens would willingly pay very little to reduce cyclical fluctuations

a general equilibrium model for industries with price and service competition this paper develops a stochastic general equilibrium inventory model for an oligopoly in which all inventory constraint parameters are endogenously determined we propose several systems of demand processes whose distributions are functions of all retailers prices and all retailers service levels we proceed with the investigation of the equilibrium behavior of infinite horizon models for industries facing this type of generalized competition under demand uncertainty we systematically consider the following three competition scenarios 1 price competition only here we assume that the firms service levels are exogenously chosen but characterize how the price and inventory strategy equilibrium vary with the chosen service levels 2 simultaneous price and service level competition here each of the firms simultaneously chooses a service level and a combined price and inventory strategy 3 two stage competition the firms make their competitive choices sequentially in a first stage all firms simultaneously choose a service level in a second stage the firms simultaneously choose a combined pricing and inventory strategy with full knowledge of the service levels selected by all competitors we show that in all of the above settings a nash equilibrium of infinite horizon stationary strategies exists and that it is of a simple structure provided a nash equilibrium exists in a so called reduced game we pay particular attention to the question of whether a firm can choose its service level on the basis of its own input characteristics i e its cost parameters and demand function only we also investigate under which of the demand models a firm under simultaneous competition responds to a change in the exogenously specified characteristics of the various competitors by either i adjusting its service level and price in the same direction thereby compensating for price increases decreases by offering improved inferior service or ii adjusting them in opposite directions thereby simultaneously offering better or worse prices and service

the role of tax bases and collections costs in the determination of income tax rates seigniorage and inflation a growing theoretical literature on optimal taxation predicts that governments will set the tax rates on money holdings and on more traditional tax bases to minimize the deadweight losses of collecting government revenue under the presumption that relative collection costs and tax bases have not changed significantly over time the empirical time series seigniorage literature has focused on the theory s tax smoothing implication finding only weak support we show that changes in collections costs and tax bases played an important role in the determination of tax composition and find stronger support for tax smoothing when this is taken into account

westernization of asian diets and the transformation of food systems implications for research and policy abstract rapid economic and income growth urbanization and globalization are leading to a dramatic shift of asian diets away from staples and increasingly towards livestock and dairy products vegetables and fruit and fats and oils while the diversification of diets away from the traditional dominance of rice with rising incomes is expected and observed current food consumption patterns are showing signs of convergence towards a western diet the diet transition is characterized by increased consumption of wheat temperate fruit and vegetables and high protein and energy dense food globalization and the consequent global interconnectedness of the urban middle class is the driving force behind the convergence of diets the rapid spread of global supermarket chains and fast food restaurants is reinforcing the above trends the growing demand for diet diversity cannot be met solely by the traditional food supply chain it requires the modernisation of the food retail sector and the vertical integration of the food supply chain in effect linking the consumers plate to the farmers plow as a consequence asian agriculture is on an irreversible path leading away from its traditional pre occupation with cereal crop production especially rice towards a production system that is becoming increasingly commercialized and diversified this paper describes the determinants and trends in the diversification and westernization of asian diets implications of the evolving demand trends for food supply and retail systems are presented the paper discusses the prospects for small farmer participation in the emerging food supply system with a particular emphasis on asian rice production systems finally the paper considers emerging challenges for food policy small holder welfare and agricultural research and development priorities

a political model of monetary policy with application to the real fed funds rate abstract we construct an empirical model of u s monetary policy assuming that the federal reserve is an ordinary federal bureaucracy we use the real federal funds rate as our policy measure and show the existence of significant executive legislative and bureaucratic influence on the real rate of interest from 1961 to 1996 we find that presidential party is an adequate statistical measure of executive influence and that the voting scores of the senate banking committee leadership best represent legislative influence we argue that political changes cause systematic and predictable changes in monetary policy

explaining u s federal deficits 1889 1998 i introduction seater 1993 attempted to provide a common basis for assessing empirical studies of the effects of deficit spending he concluded that evidence of the existence of appreciable effects of u s deficits on macroeconomic variables is questionable in other words the data do not allow for a confident rejection of ricardian equivalence in a world with no macroeconomic effects from deficit spending full information and no distinctions between political and economic markets fluctuations in deficits merely reflect government financing considerations of secondary importance in contrast to this view of the world deficits and surpluses are treated as an important topic in everyday affairs and discourse politicians talk about deficits and surpluses regularly when calling for higher or lower taxes more or less spending revisions in social security funding and other changes in public policy economists and political analysts continue to debate why deficits became a regular feature of federal fiscal management from the late 1960s into the 1990s these debates have spurred divergent theories and conjectures leading to different empirical hypotheses and variables of interest moreover existing empirical studies of the subject have utilized diverse econometric techniques and specifications as a result the competing hypotheses concerning deficit spending have not been tested against one another in a systematic fashion in this article our principal aim is to analyze the different explanations of u s federal deficits jointly estimating competing hypotheses about deficit fluctuations in a generalized reduced form empirical model to achieve this goal we collected and utilized a time series of data running from 1889 to 1998 the apparent paradox between the seemingly innocuous effects of deficits and the political preoccupation with them may owe its existence to one or more reasons limited and noisy information among voters differences between economic and political markets inaccuracy in the measured macroeconomic effects of deficits or other reasons we do not attempt an explanation of why deficits which seemingly exhibit no or small real effects ricardian equivalence could lead politicians and voters to treat deficits as if the ricardian hypothesis were rejected instead we treat explanations of deficits that stem from ricardian premises as one of several hypotheses to be tested ii competing hypotheses we first describe the leading explanations of deficit spending organizing them around common theoretical principles 1 tax smoothing the explanation of deficits which follows directly from a ricardian equivalence theory is the tax smoothing theory developed by barro 1979 2 if deficits generate no real macroeconomic effects and the influences of political institutions and politicians are ignored then optimal public financing considerations govern the use of deficit spending simply put fiscal authorities raise revenue to meet spending needs through income taxation but both spending and income the tax base are subject to uncertain and temporary movements minimization of the deadweight costs of raising a given amount of revenue requires keeping tax rates steady in the face of purely temporary changes in income or spending this is accomplished by running deficits when income is temporarily low or spending is temporarily high and running surpluses in the opposite case imposing a binding no ponzi game npg constraint leads to similar long term behavior of deficits as implied by optimal finance models the npg condition requires that the present value of taxes must equal the present value of spending plus the initial value of debt spending and revenue must share a long term common trend so that primary deficits will be stationary over a long time series deficits and surpluses will offset each other

food consumption and economic development in turkey and european union countries this study investigates the relationship between food consumption and economic development in turkey and european union countries differences in food diets are analysed by using data on per capita consumption in caloric terms based on the period from 1970 to 2000 the cluster analysis is employed to derive country grouping on the basis of similarities in dietary structure in the 1970 and 2000 existence of a trend towards a common european diet is explored with beta convergence the empirical results show that per capita food consumption is becoming less responsive to changes in income and appears to be reaching a ceiling in the majority of eu countries and turkey however the share of animal products in food consumption diet is low and income expenditure elasticity of animal products is higher with 0 84 values in turkey than that in european countries in 2000 there are great differences in dietary structure between turkey and the european union differences also exist between european union countries

optimal taxation and optimal tax systems the theory of optimal taxation has for the pas two decades been the reigning normative approach of taxation this paper argues that in its current state optimal tax theory is incomplete as a guide to action concerning many critical issues in tax policy it is incomplete because it has not yet come to terms with taxation as a system of coercively collecting revenues from individuals who will tend to resist the coercive nature of collection taxes implies that the resource cost of implementing a tax system have been and will continue to be a critical determinant of appropriate tax policy the paper first presents the three cornerstone propositions of optimal tax theory and then it discusses the influence of these propositions on recent tax policy developments it concludes by sketching an alternative to optimal taxation called the theory of optimal tax systems which embraces the insights of optimal taxation but also considers the technology of raising taxes and the constraints placed upon tax policy by that technology the optimal tax systems perspective is shown to shed light on the choice of tax instruments the problem of tax evasion and the appropriate tax treatment of capital income this abstract was borrowed from another version of this item

dispersed communication by central bank committees and the predictability of monetary policy decisions the paper asks whether members of central bank decision making committees should communicate with the public in a collegial manner by conveying the consensus or majority view of the committee or in an individualistic way by providing the diversity of views among the committee members it finds that more active as well as more consistent communication by committee members improves the predictability of monetary policy decisions significantly this effect is sizeable as communication dispersion across committee members accounts on average for one third to one half of the market s prediction errors of fomc policy decisions moreover more active and more consistent communication are found to also reduce the degree of uncertainty about the future path of interest rates these findings suggest that a collegial communication which stresses the consensus view on policy inclinations can enhance the effectiveness of central bank communication

measuring the fed s revenue from money creation abstract the national accounts include the fed s payments to the treasury as a component of corporate taxes these payments constituted 22 of reported corporate profits taxes in 1981 alternative concepts of inflationary finance are considered with measurements provided for the post world war ii period

after sales service competition in a supply chain does uncertainty affect the conflict between profit maximization and customer satisfaction abstract after sales services are a key strategic tool in the durable consumer product market they allow a manufacturer and a retailer to capture more sales and profit less obvious however is how the uncertainty of the customer s needs for after sales services influences after sales service decisions as an extension of kurata and nam s 2010 international journal of production economics 127 1 136 146 work in this paper we explore the effect of uncertainty on after sales service decisions by comparing several information structures in a two stage supply chain the model presented in this paper demonstrates that uncertainty may temporally alleviate the discrepancy between customers optimal service level and a firm s service decisions based on maximizing profits referred to here as accidental outperformance however ultimately uncertainty will never improve supply chain performance we determine probabilities that such accidental outperformance may mislead the firm into making erroneous after sales service decisions due to misunderstandings regarding uncertainty in addition our analysis shows that a firm s effort to provide efficient service operations will increase the chance of accidental outperformance based on the analytical results we also provide several practical insights for business

the world per capita electricity consumption distribution signs of convergence abstract considering residential per capita electricity consumption as one of the most suitable economic welfare indicators the aim of this paper is to explore worldwide differences on this variable over the period 1980 2007 the paper adds to the standard practice of and convergence analysis by tracking the external shape and time evolution of the entire distribution applying nonparametric techniques density functions and stochastic kernels to a sample of 98 countries the main finding is that a weak process of electricity consumption convergence has taken place this reduction of disparities is clearly related to at least three issues firstly the rapid economic changes experienced by some developing countries secondly the energy conservation policies implemented by most developed countries following the first oil shock and thirdly the growing awareness on energy issues in rich countries notwithstanding this the ergodic distribution on per capita electricity consumption indicates that large cross country disparities will persist in the long run

a public choice theory of the great contraction the conventional chicago wisdom about the great contraction is that it was the result of a massive policy failure according to this view the collapse of the economy was brought about mostly by the fact that the monetary policymakers of the day were more concerned with internal power struggles than with supplying reserves to member banks an explanation which with apologies to professor stigler must have elicited uproarious laughter at the bankers club it has been our purpose in this paper to suggest an alternative theory briefly stated the restrictive monetary policy pursued by the fed from 1929 to 1933 was motivated by the economic interests of member banks the fed s policy produced a massive differential failure rate between member and nonmember banks in which the latter were eliminated at a rate at least five times higher than the former fed member banks faced substantially less competition in the banking market after the house cleaning than before although all banks suffered net losses in the short run in the long run member bank profitability was enhanced by the reduction in the number of nonmember competitors at the same time the fed itself benefitted from a substantial increase in the proportion of the total banking system within its bureaucratic jurisdiction and from a change in its method of finance putting the great contraction in interest group terms we suggested that the fed was acting as the agent of congressmen serving on important oversight committees who in turn were representing the interests of the member banks in their states due to interstate branching restrictions the state is the relevant geographic market within which banks compete we tested this hypothesis using bank failure rate data across states and found that holding other things equal the failure rates of nonmember banks in the early 1930s were significantly higher in states with representation on the house banking and currency committee of course not even friedman and schwartz 1963 299 301 argue that fed policy was the sole direct cause of the great contraction but instead maintain that the fed acted in such a way as to take a relatively severe contraction and turn it into by far the most severe business cycle contraction in the whole of u s history but to the extent that the great contraction was worsened by fed policy and this in turn led to the succession of events called the great depression the latter was a side effect of economically rational interests of federal reserve member banks to say the least this would appear to have been an enormously inefficient method of obtaining the postulated benefits certainly there were other less costly methods available by which member banks could have reduced the number of their nonmember rivals this is perhaps the most difficult problem our theory of the great contraction confronts we can offer two responses first although the literature on the great depression tends to focus on fluctuations in national macroeconomic aggregates e g the money supply unemployment and so on it is clear that the severity of the depression differed radically across states states with relatively large agricultural sectors tended to be especially hard hit suffering the highest rates of unemployment and the most significant numbers of bank failures by contrast states in some other areas most notably new england and the southeast seemed to be less seriously affected we note that in some of our regressions the number of nonmember bank failures was negatively and significantly related to state unemployment rates in 1934 this is certainly not conclusive evidence but it does suggest a pattern of differential costs associated with the great contraction that is the costs of providing benefits to federal reserve member banks in states with representation on the relevant oversight committees may have fallen more heavily on the economies of states not so represented if so this would cast a very different light on the actual costs of these policies to the relevant political decision makers second the potential dilemma in this case is no worse than that encountered in the application of the economic theory of politics to many other kinds of government behavior economists since adam smith have ascribed protectionist trade policies to the influence of special interest groups who benefit modestly at the cost of relatively huge economic inefficiencies many other government actions that might be plausibly explained from an interest group perspective would similarly seem to involve costs to the economy which grossly outweigh the benefits special interests might reasonably expect presumably even in such seemingly extreme cases marginal benefits equal marginal costs to the relevant actors some writers have suggested that the political marketplace in modern democracies is characterized by much larger transactions costs than are normally encountered in ordinary markets see demsetz 1982 this might help explain the seemingly huge discrepancies we observe between apparent concentrated benefits and diffused costs in depression era monetary policy in any event this problem is not peculiar to our theory but is shared by many applications of the interest group model of government it is worth emphasizing that the events we have described do fall into the interest group model s stylized depiction of concentrated benefits versus diffuse costs moreover without having a complete picture of all of the options available to the monetary policymakers we cannot be sure that any of the alternatives was in fact more efficient we do know the path that was chosen and that contrary to the conventional wisdom this path had a

a positive model of reserve requirements and interest on reserves a clearinghouse interpretation of the federal reserve system this paper develops a positive model of reserve requirements and interest on reserves based on the observation that congress exempted the fed from a legal restriction that had prevented private clearinghouses from issuing their own currency eliminating the restriction provided the fed with a source of revenue that could be used to finance general government outlays and to pay implicit interest on reserves the model implies that the government s financing requirements help explain reserve requirement movements and that interest rates on reserves vary with market loan rates cointegration error correction and granger causality tests provide supporting evidence
