are corporate tax rates or countries converging abstract the statutory rate and effective tax rate imposed on corporation income as well as the dispersion of these rates began to decline in the 1980s is this due to changes in the domestic determinants of corporate taxation or increases in international pressures for tax competition this paper finds clear evidence that the corporate tax rate is insulated from a country s revenue needs across countries there is no association of the expenditure gdp ratio with the corporate statutory rate and only weak evidence of a positive association with the average rate there is suggestive but not definitive evidence that the domestic role of the corporate tax as a backstop to the individual income tax is important across countries there is indeed a strong association between the top individual rate and the top statutory corporate rate there is intriguing evidence about the role of international competitive pressures on corporate taxation measures of openness are negatively associated with statutory corporate rates although not with revenues collected as a fraction of gdp strikingly larger more trade intensive countries do collect more corporate tax but this may be because these countries are more attractive venues for investment

note periodic review s s policies for joint replenishment inventory systems this note deals with the joint replenishment problem with stochastic demands a new class of policies called ps s policy is proposed for this problem the proposed policy uses independent periodic review s s policies for each item results on test problems show that the proposed policy is superior to other classes of policies for the problem

financial intermediation and endogenous growth an endogenous growth model with multiple assets is developed agents who face random future liquidity needs accumulate capital and a liquid but unproductive asset the effects of introducing financial intermediation into this environment are considered conditions are provided under which the introduction of intermediaries shifts the composition of savings toward capital causing intermediation to be growth promoting in addition intermediaries generally reduce socially unnecessary capital liquidation again tending to promote growth

a theory of interregional tax competition a general equilibrium model is constructed to study tax competition where local governments compete for capital by holding down property tax rates and public expenditure levels an exact definition of tax competition is provided and both the existence and nonexistence of tax competition are shown to be theoretically possible it is argued however that tax competition must occur under empirically reasonable conditions inefficiency in public production is also explicitly modeled the amount of capital used to produce a given level of public service output is shown to be greater than that which is required to minimize costs evaluated at the prices facing private firms

is quantity theory still alive this paper investigates whether the quantity theory of money is still alive we argue that it is but that the slippage is not negligible for countries with low inflation the relationship between average inflation and the growth rate of money is tenuous at best a correction for variation in output growth and the opportunity cost of money using theory implied elasticities helps explain the slippage for the period since 1990 inflation targeting at low rates of inflation makes it harder to establish the long run relationship between monetary growth and inflation

money and growth an alternative approach this paper takes an alternative approach to the topic of money and growth by developing a model in which the effects of sustained capital accumulation on an evolving system of payments in addition to the conventional effects of sustained inflation on growth are examined while the effects of inflation on growth are small the effects of growth on the monetary system are substantial the results are consistent with ideas about money and growth contained in work that predates that of james tobin and miguel sidrauski as well as with evidence that money and asset demands vary systematically within economies as they develop copyright 1994 by american economic association

how elastic are national corporate income tax bases in oecd countries the role of domestic and foreign tax rates abstract to what extent do reductions in corporate income tax cit rates attract foreign tax bases what are the revenue implications of a unilateral tax reduction when tax bases are internationally mobile these questions are explored using annual data from 17 oecd countries spanning the period 1982 to 2005 controlling for fixed country effects year effects and country time trends and subjecting our results to an extensive robustness analysis we find i a country s aggregate reported corporate profits are negatively and significantly affected by cit rate reductions in neighbouring countries ii a unilateral reduction in the domestic cit rate results in lower domestic cit revenues

optimal monetary policy and economic growth abstract a question at the center of many analyses of optimal monetary policy is why do central banks never implement the friedman rule to the list of answers to this question we add neoclassical production specifically the tobin effect as one possible explanation to that end we study an overlapping generations economy with capital where limited communication and stochastic relocation create an endogenous transactions role for fiat money we assume a production function with a knowledge externality romer style that nests economies with endogenous growth ak form and those with no long run growth the diamond model the tobin effect is shown to be always operative under crra preferences a mild degree of social increasing returns is sufficient but not necessary for some positive inflation to dominate zero inflation and for the friedman rule to be sub optimal irrespective of the degree of risk aversion

budget spillovers and fiscal policy interdependence evidence from the states abstract this paper formalizes and tests the notion that states expenditures depend on the spending of similarly situated states we find that even after allowing for fixed state effects year effects and common random shocks among neighbors a state government s level of per capita expenditure is positively and significantly affected by the expenditure levels of its neighbors ceteris paribus a one dollar increase in a state s neighbors expenditures increases its own expenditure by over 70 cents

the determinants of municipal tax rates in british columbia in this paper we study the regional pattern of municipal business property tax rates in the province of british columbia reduced form tax setting equations produce some evidence that municipal governments respond to tax changes in neighbouring jurisdictions a joint investigation of the determinants of tax base and municipal taxation decisions however reveals that it is difficult to interpret this response as arising primarily out of competition over tax base there is also some evidence that municipal tax rates are sensitive to taxes set on the same base by super municipal bodies jel classification c33 h71 les determinants des taux d imposition municipale en colombie britannique dans ce memoire les auteurs etudient le pattern regional des taux d imposition municipale sur la propriete fonciere commerciale dans la province de la colombie britannique on montre a l aide d un modele en forme reduite d equations de definition des taux d imposition que les gouvernements municipaux reagissent aux changements dans les taux d imposition dans leur voisinage cependant un examen conjoint des determinants de la base d imposition et des decisions municipales montre qu il est difficile d interpreter cette reaction comme emanant d une concurrence fiscale on montre aussi que les taux d imposition municipale sont sensibles aux niveaux de fiscalite imposes sur la meme base par les autorites supra municipales

the real bills doctrine versus the quantity theory a reconsideration two competing monetary policy prescriptions are analyzed within the context of overlapping generations models the real bills prescription is for unfettered private intermediation or central bank operations designed to produce the effects of such intermediation the quantity theory prescription in contrast is for restrictions on private intermediation designed to separate money from credit although our models are consistent with quantity theory predictions about money supply and price level behavior under these two policy prescriptions the models imply that the quantity theory prescription is not pareto optimal and the real bills prescription is

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

periodic versus can order policies for coordinated multi item inventory systems the coordinated multi item inventory problem refers to the problem of managing inventories where there is a joint fixed cost for replenishing plus an item by item fixed cost for each item included in the replenishment order given that the optimal solution is likely to be too complex attention has focused on fixed heuristics and in particular can order or s c s policies this paper makes two contributions first a new lower bound on the cost of the optimal policy is proposed in order that the performance of heuristics may be measured second motivated by the lower bound a simple periodic policy is proposed and shown to be an improvement over can order policies for many data sets

corporate tax elasticities a reader s guide to empirical findings corporate taxes exert a variety of effects on business behaviour a wealth of empirical evidence assesses the magnitude of these behavioural margins of taxation this article offers an up to date review and aims to provide common ground by computing for each distortion the semi elasticity of the corporate tax base we pay particular attention to international investment where it is not a priory clear whether marginal investment decisions or discrete locations are most important using anextension of the meta analysis of de mooij and ederveen 2003 we explore the extent to which existing studies reveal differences in effect size between the intensive and extensive margins of international investment

the welfare cost of inflation in a cash in advance economy with costly credit the paper presents a modification of the lucas stokey 1983 cash in advance economy in which the representative consumer decides based on relative prices which goods to buy with cash and which with costly credit an explicit baumol 1952 condition emerges that guides this consumer choice deriving and estimating a closed form welfare cost function in an example economy the paper shows that the welfare cost of inflation depends on the margins of substitution the consumer avoids inflation through costly credit and faces higher welfare costs of inflation than in standard cash in advance economies

the 2bin system for controlling medical supplies at point of use abstract the increase in cost of supplies and services is outpacing the increase in revenues at many hospitals to address this cost increase hospitals are seeking more efficient ways to store and manage vast inventories of medical supplies a parsimonious and efficient inventory system which we call 2bin is becoming increasingly popular in north american hospitals under the 2bin system inventory is stored in two equal sized bins 2bin systems are reviewed periodically and empty bins are replenished in recent years the adoption of rfid technology for 2bin systems is allowing continuous time tracking of empty bins increasing inventory visibility in this paper we model the 2bin inventory system under periodic and continuous review for periodic review we show that the long run average cost per unit time is quasi convex enabling a simple search for the optimal review cycle for continuous review we present a semi markov decision model characterize the optimal replenishment policy and provide a solution approach to obtain the long run average cost per unit time using data obtained from hospitals currently using rfid enabled 2bin systems we estimate the economic benefits of using the best periodic review length i e parameter optimization and of using a continuous review inventory policy i e policy improvement we characterize system conditions such as the number of medical supplies used replenishment costs stock out costs etc that favor each option and provide insights to hospital management on system design considerations that favor the use of periodic or continuous review

money and interest in a cash in advance economy the authors analyze an aggregative general equilibrium model in which the use of money is motivated by a cash in advance constraint applied to purchases of a subset of consumption goods the system is subject to both real and monetary shocks which are economy wide and observed by all they develop methods for verifying the existence of characterizing and explicitly calculating equilibria copyright 1987 by the econometric society

pigou tiebout property taxation and the underprovision of local public goods abstract pigou s proposition that the use of distorting taxes rather than neutral head taxes reduces public service levels is examined in this paper a simple model with a national system of competing local governments is utilized to demonstrate that the use of a distorting property tax on mobile capital decreases the level of residential public services the case where public services are an intermediate producer good is also considered

what is a liquidity crisis abstract this paper investigates the role of liquidity it is argued that the firm holds money as a guarantee of solvency to its contractual partners by holding liquid assets the firm is able to increase the efficiency of its contracts variations in the opportunity cost of holding money cause variations in the firm s demand for money and consequent variations in the frequency of contract failures this mechanism is suggested as an alternative explanation of the observed relationship between money income and interest rates

money real interest rates and output a reinterpretation of postwar u s data this paper reexamines both monthly and quarterly u s postwar data to investigate if the observed comovements between money real interestrates prices and output are compatible with the money real interest output link suggested by existing monetary theories of output which include both keynesian and equilibrium models the major empirical findings are these 1 in both monthly and quarterly data we cannot reject the hypothesis that the ex ante real rate is exogenous or granger causally prior in the context of a four variable system which contains money prices nominal interest rates and industrial production 2 in quarterly data there is significantly more information con tained in either the levels of expected inflation or the innovationof this variable for predicting future output given current and lagged output than in any other variable examined money actualinflation nominal interest rates or ex ante real rates the effect of an inflation innovation on future output is unambiguously negative the first result casts strong doubt on the empirical importance of existing monetary theories of output which imply that money should have a causal role on the ex ante real rates the second result would appear incompatible with most demand driven models of output in light of these results we propose an alternative structural model which can account for the major dynamic interactions among the variables this model has two central features i output is unaffected by money supply and ii the money supply process is motivated by short run price stability this abstract was borrowed from another version of this item

on efficient distribution with private information this paper is a study of the dynamics of the efficient distribution of consumption in an exchange economy with many consumers each of whom is subject to private idiosyncratic taste shocks we propose a recursive method for finding feasible allocations that are incentivecompatible and that are pareto optimal within this set the method is applied to several parametric examples we find that in an efficient allocation the degree of inequality continually increases with a diminishing fraction of the population receiving an increasing fraction of the resources we discuss the extent to which these allocations can be decentralized via market arrangements this paper is a study of the dynamics of the efficient distribution of consumption in an exchange economy with private information the economy we study has a constant endowment flow of a single non storable consumption good which is to be allocated each period among a large number of consumers each period these consumers experience unpredictable idiosyncratic privately observed taste shocks affecting their marginal utility of current consumption efficiency dictates that more resources be allocated to those consumers who in any given period have a high marginal utility of current consumption

liquidity preference and financial intermediation we examine the characteristics of optimal monetary policies in a general equilibrium model with incomplete markets markets are incomplete because of uninsured preference uncertainty and because productive capital is traded infrequently rational individuals are willing to hold a liquid asset money at a premium monetary policy interacts with existing flnancial institutions to determine this premium as well as the level of precautionary holdings we show that inflation is expansionary and that the optimal inflation rate is positive if there is no operative banking system the tobin effect otherwise efficiency requires that money be undominated in its rate of retum the friedman rule we analyse the preference for liquidity and evaluate the effects of monetary policy in a framework where individuals optimize and goods and asset markets are competitive liquidity needs of individuals and characteristics of assets are consequences of the structure of preferences technology and information equilibrium is compatible with diiferences in the rates of retum on assets differing in liquidity with divergences between household savings and aggregate investment in productive capital and distortion of household consumption plans we examine how these quantities are determined in altemative financial environments the extent to which monetary or interest rate policies are effective and desirable and the relative efficiency of altemative instruments which serve private liquidity needs we find that monetary policy is effective and infiation is expansionary if the consumption plans of individuals are constrained by the lack of liquidity at the same time such expansion can be welfare inferior intermediation which allows liquid assets to be issued against productive investment is both feasible and desirable unlike infiation intermediation achieves welfare enhancing expansion this allows a comparison of the tobin effect tobin 1965 and the friedman mle friedman 1969 in a general equilibrium model cmdely speaking the first indicates that infiation is desirable while the other claims that defiation is the difference as we show depends on the degree of intermediation money and productive capital are simultaneously held by individuals even when money has a lower rate of retum this is due to the fact that money is liquid it can be used to pay for goods at any time and in all states of nature capital on the other

asset markets and equilibrium processes the failure of the asset market to be complete causes serial dependence in output and prices which is suboptimal we consider an economy with white noise shocks when the asset market is complete an optimal competitive allocation inherits this strong stationarity when the asset market is only sequentially complete prices and output necessarily display serial dependence at equilibrium the further incompleteness of a monetary economy explains co movements in real and nominal variables

optimality of the friedman rule in economies with distorting taxes abstract we find conditions for the friedman rule to be optimal in three standard monetary models our main contribution is to shed light on two issues in the literature first the conventional view maintains that when money is a final good its services should be taxed moreover if money demand is interest inelastic its services should be taxed heavily we show that this view is incorrect second there is an ongoing controversy about whether the optimality of the friedman rule is connected to the intermediate goods result from public finance we resolve this controversy by showing a deep connection between these results
