re examination of uniform commodity taxes under a non linear income tax system and its implication for production efficiency abstract this paper shows that the result of uniform commodity tax under nonlinear income taxation by atkinson and stiglitz 1976 no longer holds if the production side of an economy is taken into the consideration in particular imposing a non uniform commodity tax can pareto improve welfare even under nonlinear income taxation in addition the paper shows that if the government uses a nonlinear income tax system for income redistribution then the introduction of distortions in the public sector can pareto improve welfare contrary to the results in diamond and mirrlees 1971

optimal dynamic pricing of inventories with stochastic demand over finite horizons in many industries managers face the problem of selling a given stock of items by a deadline we investigate the problem of dynamically pricing such inventories when demand is price sensitive and stochastic and the firm s objective is to maximize expected revenues examples that fit this framework include retailers selling fashion and seasonal goods and the travel and leisure industry which markets space such as seats on airline flights cabins on vacation cruises and rooms in hotels that become worthless if not sold by a specific time we formulate this problem using intensity control and obtain structural monotonicity results for the optimal intensity resp price as a function of the stock level and the length of the horizon for a particular exponential family of demand functions we find the optimal pricing policy in closed form for general demand functions we find an upper bound on the expected revenue based on analyzing the deterministic version of the problem and use this bound to prove that simple fixed price policies are asymptotically optimal as the volume of expected sales tends to infinity finally we extend our results to the case where demand is compound poisson only a finite number of prices is allowed the demand rate is time varying holding costs are incurred and cash flows are discounted the initial stock is a decision variable and reordering overbooking and random cancellations are allowed

durable goods and product obsolescence the issue of product obsolescence is addressed by examining the optimal sales strategy of a monopolist firm that may introduce an improved version of its current product consumers expectations of a forthcoming product lowers the price that they are willing to pay for the current product because of its loss in value due to obsolescence the new product is characterized by consumers increased willingness to pay and by its competitive interaction with the old product these characteristics affect the tradeoff that the firm makes between the cost of waiting for new product sales versus the cost of cannibalizing these sales we analyze the effect of these characteristics of the new product on the firm s optimal sales strategy we consider the various policy measures available to the firm including limiting initial sales in order to lower cannibalization of the new product buying back the earlier version of the product in order to generate greater demand for the new product and announcements of future product introductions we find that for modest levels of product improvement the firm s optimal policy is to phase out sales of the old product while for large improvements a buy back policy is more profitable lastly we find that the firm is better off if it informs consumers whether a new product is forthcoming

frictionless commerce a comparison of internet and conventional retailers there have been many claims that the internet represents a new nearly frictionless market our research empirically analyzes the characteristics of the internet as a channel for two categories of homogeneous products books and cds using a data set of over 8 500 price observations collected over a period of 15 months we compare pricing behavior at 41 internet and conventional retail outlets we find that prices on the internet are 9 16 lower than prices in conventional outlets depending on whether taxes shipping and shopping costs are included in the price additionally we find that internet retailers price adjustments over time are up to 100 times smaller than conventional retailers price adjustments presumably reflecting lower menu costs in internet channels we also find that levels of price dispersion depend importantly on the measures employed when we compare the prices posted by different internet retailers we find substantial dispersion internet retailer prices differ by an average of 33 for books and 25 for cds however when we weight these prices by proxies for market share we find dispersion is lower in internet channels than in conventional channels reflecting the dominance of certain heavily branded retailers we conclude that while there is lower friction in many dimensions of internet competition branding awareness and trust remain important sources of heterogeneity among internet retailers

optimal dynamic pricing for perishable assets with nonhomogeneous demand we consider a dynamic pricing model for selling a given stock of a perishable product over a finite time horizon customers whose reservation price distribution changes over time arrive according to a nonhomogeneous poisson process we show that at any given time the optimal price decreases with inventory we also identify a sufficient condition under which the optimal price decreases over time for a given inventory level this sufficient condition requires that the willingness of a customer to pay a premium for the product does not increase over time in addition to shedding managerial insight these structural properties enable efficient computation of the optimal policy numerical studies are conducted to show the revenue impact of dynamic price policies price changes are set to compensate for statistical fluctuations of demand and to respond to shifts of the reservation price for the former our examples show that using optimal dynamic optimal policies achieves 2 4 7 3 revenue improvement over the optimal single price policy for the latter the revenue increase can be as high as 100 these results explain why yield management has become so essential to fashion retailing and travel service industries

foreign ownership and corporate income taxation an empirical evaluation abstract foreign ownership allows countries to effectively export part of their corporate tax burden hence countries with high foreign ownership are expected to impose relatively high corporate taxes the findings of this paper suggest that there indeed is an economically significant positive relationship between foreign ownership and tax burdens in europe already significant foreign ownership levels in europe offer an explanation for the absence of a race to the bottom in corporate tax levels

international effects of tax reforms in an open economy with international capital flows there is an equivalence relation between income tax consumption tax international borrowing tax and an external interest earning tax this paper analyzes tax reform involving shifts between income and consumption taxes in this setting it is shown that the real effects of such revenue neutral tax reform depend critically on the country s current account position and the nature of the reform in particular whether the world interest rate rises or falls as a consequence of a budget deficit depends on the tax system in force the analysis provides a clear rationale for the international coordination of tax policies copyright 1989 by royal economic society

durable goods monopolists durable goods monopolists face special problems because the sale of their products creates a secondhand market not controlled by the monopolist to the extent the monopolist is able to rent his product rather than sell it or to make binding promises about his future production such problems are ameliorated given the inability to do the above the monopolist is led to producing goods less durable than those produced by either competitive firms or monopolist returns a reverse averch johnson result that monopolist sellers may invest less in fixed costs including plant modernization and research and development than would the renters is shown it is also shown that even though sellers have less monopoly power than renters and nondurable goods monopolists it is possible that the seller will cause a greater deadweight loss than the other types of monopolies

ramsey optimal tax reforms and real exchange rate dynamics abstract we solve the ramsey optimal tax plan for a small open economy with an endogenously determined real exchange rate the open economy constrains the government s setting of the capital income tax rate since physical capital cannot be dominated in rate of return by foreign assets however the endogenous real exchange rate loosens this constraint relative to a one good open economy model in which the real exchange rate is necessarily fixed we find that the dynamics of the two good small open economy model more closely resemble those of a closed economy model than a one good small open economy model

can state taxes redistribute income abstract the evidence presented in this paper supports the basic theoretical presumption that state and local governments cannot redistribute income since individuals can avoid unfavorable taxes by migrating to jurisdictions that offer more favorable tax conditions a relatively unfavorable tax will cause gross wages to adjust until the resulting net wage is equal to that available elsewhere the current empirical findings go beyond confirming this long run tendency and show that gross wages adjust rapidly to the changing tax environment thus states cannot redistribute income for a period of even a few years the adjustment of gross wages to tax rates implies that a more progressive tax system raises the cost to firms of hiring more highly skilled employees and reduces the cost of lower skilled labor a more progressive tax thus induces firms to hire fewer high skilled employees and to hire more low skilled employees since state taxes cannot alter net wages there can be no trade off at the state level between distribution goals and economic efficiency shifts in state tax progressivity by altering the structure of employment in the state and distorting the mix of labor inputs used by firms in the state create deadweight efficiency losses without achieving any net redistribution

on pricing of perishable assets with menu costs we consider dynamic pricing of perishable assets in the presence of price sensitive renewal demand processes unlike the existing works in the literature we explicitly incorporate non negligible price change costs which reflects the revenue management practice more realistically these costs are also known as menu costs in the economic literature the objective is to maximize the discounted expected profit for an initial inventory of q items by determining the selling prices dynamically we employ a dynamic programming approach and formulate a model that captures the price demand relationship we establish some theoretical results on the properties of the problem at hand specifically we establish the sufficient conditions under which the within period profit is concave in the selling price and in the remaining shelf life and furthermore show the structure of the myopically and asymptotically optimal pricing policy in a numerical study we investigate the impact of various system parameters and in particular the existence of menu costs on pricing decisions we observe that ignoring menu costs may be significantly misleading for the implementation of revenue management we also propose four implementable policy heuristics and examine their performances our findings support some results previously obtained in settings with continuous pricing and negligible price change costs and contradict some others 2009 published by elsevier b v

dynamic pricing of inventory capacity with infrequent price changes we consider a problem of dynamically pricing a single product sold by a monopolist over a short time period if demand characteristics change throughout the period it becomes attractive for the company to adjust price continuously to respond to such changes i e price discriminate intertemporally however in practice there is typically a limit on the number of times the price can be adjusted due to the high costs associated with frequent price changes if that is the case instead of a continuous pricing rule the company might want to establish a piece wise constant pricing policy in order to limit the number of price adjustments such a pricing policy which involves optimal choice of prices and timing of price changes is the focus of this paper we analyze the pricing problem with a limited number of price changes in a dynamic deterministic environment in which demand depends on the current price and time and there is a capacity inventory constraint that may be set optimally ahead of the selling season the arrival rate can evolve in time arbitrarily allowing us to model situations in which prices decrease increase or neither we consider several plausible scenarios where pricing and or timing of price changes are endogenized various notions of complementarity single crossing property supermodularity and total positivity are explored to derive structural results conditions sufficient for the uniqueness of the solution and the monotonicity of prices throughout the sales period furthermore we characterize the impact of the capacity constraint on the optimal prices and the timing of price changes and provide several other comparative statics results additional insights are obtained directly from the solutions of various special cases

integration of inventory and pricing decisions with costly price adjustments motivated by the widespread adoption of dynamic pricing in industry and the empirical evidence of costly price adjustments in this paper we consider a periodic review inventory model with price adjustment costs that consist of both fixed and variable components in each period demand is stochastic and price dependent the firm needs to coordinate the pricing and inventory replenishment decisions in each period to maximize its total discounted profit over a finite planning horizon we develop the general model and characterize the optimal policies for two special scenarios namely a model with inventory carryover and no fixed price change costs and a model with fixed price change costs and no inventory carryover finally we propose an intuitive heuristic policy to tackle the general system whose optimal policy is expected to be very complicated our numerical studies show that this heuristic policy performs well

optimal price markup policy for an inventory model with random price fluctuations and option for additional purchase abstract in this paper based on the analysis of empirical data of dealer and retailer prices and sales of cement as a prototype of functional products we develop a probabilistic inventory model for the situation when dealer s selling price fluctuates and affects the retailer s selling price demand is a function of price markup and retailer s purchase price dynamic price markup policy is proposed and optimal length of replenishment cycle and order quantity is obtained concavity of the profit function with respect to price markup is discussed a procurement policy which considers opportunity of purchase at a low price before the end of the optimal replenishment cycle is proposed and compared with other policies algorithm numerical examples sensitivity analysis and managerial insights are presented

an analysis of the corporate income tax policy of less developed countries unlike developed countries corporate tax rather than personal tax revenues are the greater source of public finance for less developed countries ldcs this paper analyses the corporate income tax policy for a large panel of ldcs over the period 1980 2006 the analysis shows that although the corporate tax rate has been decreasing in ldcs corporate tax revenues have been increasing as a percentage of total tax revenues and gdp contrary to standard tax competition theory there is also strong evidence that corporate income taxes in ldcs are increasing in the country s openness as measured by capital mobility the analysis also shows that the corporate tax rate is increasing in the personal tax rate as income shifting theory predicts however this has not translated into increased corporate tax revenues of equal interest is the lack of evidence of a relationship between the ldc s government revenue needs and its corporate tax rate

the efficiency paradox bureaucratic and organizational barriers to profitable energy saving investments abstract the paradox of why profitable energy saving investments are not undertaken continues to provoke debate the underlying phenomenon might be called the efficiency paradox because it represents a case in which business firms which are often presumed or taken axiomatically to be economically efficient make decisions that do not maximize profits new data from one of the us environmental protection agency s voluntary pollution prevention programs enables this paradox to be explored statistically the data show that both the level and variation in returns to lighting upgrade investments cannot be explained by standard economic models substantial gains in energy efficiency can be achieved without sacrificing profitability both economic and organizational factors account for some of the variation in observed returns to these investments but the results suggest a need for improved and more comprehensive theories of the investment behavior of firms and other organizations

capital income and profit taxation with foreign ownership of firms abstract this paper establishes optimal rules for capital income and profits taxation in the open economy with or without foreign ownership of domestic firms we show that if there are constraints on the feasibility of profits taxation both saving and investment taxes generally enter the optimal tax package if instead profits can be fully taxed then source based investment taxes vanish if domestic firms are in part owned by foreigners then source based investment taxes can be used to shift income away from these to domestic citizens and they may even be used to finance lump sum transfers to domestic residents

analytical solutions to the dynamic pricing problem for time normalized revenue abstract in this work we consider dynamic pricing for the case of continuous replenishment an essential ingredient in such a formulation is the use of time normalized revenue or profit function in other words revenue or profit per unit time this provides the incentive to sell many items in the shortest time and of course at a high price moreover for most firms what matters most is how much revenue or profit is achieved in a certain time frame for example per year this changes the problem qualitatively and methodologically we develop a new dynamic pricing model for this formulation we derive an analytical solution to the pricing problem in the form of a simple to solve ordinary differential equation ode equation the trajectory of this ode gives the optimal pricing curve unlike many of the models existing in the literature that rely on computationally demanding dynamic programming type solutions our model is relatively simple to solve also we apply the derived equation to two commonly used price demand functions the exponential and the power functions and derive closed form pricing curves for these functions

stock index futures implications for international capital taxation abstract this paper develops a model of corporate capital structure and investor portfolio choice in an international setting the model s key feature is the stock index futures contract investors and companies specialize in securities based on tax and currency appreciation rates despite this specialization investors achieve complete diversification through futures positions nations should tax interest and capital gains equally and should not tax corporate income this contrasts with the result when futures do not exist in which foreigners desire for diversification provides countries with an incentive to use tax policy to reduce foreign ownership of domestic equity to acquire monopoly rents

taxes institutions and foreign diversification opportunities abstract investors can access foreign diversification opportunities through either foreign portfolio investment fpi or foreign direct investment fdi the worldwide tax regime employed by the us potentially distorts this choice by penalizing fdi relative to fpi in low tax countries on the other hand weak investor protections in foreign countries may increase the value of control creating an incentive to use fdi rather than fpi by combining data on us outbound fpi and fdi this paper analyzes whether the composition of us outbound capital flows reflects these incentives to bypass home and host country institutional regimes the results suggest that the residual tax on us multinational firms foreign earnings skews the composition of outbound capital flows a 10 decrease in a foreign country s corporate tax rate increases us investors equity fpi holdings by approximately 10 controlling for effects on fdi investor protections also seem to shape portfolio choices though these results are not robust when only within country variation is employed

price competition for retailers with profit and revenue targets abstract price competition for retailers has been extensively studied in the literature assuming the objective of expected profit maximization in this paper we make a major contribution by studying price competition for retailers with both profit and revenue targets consequently each retailer maximizes her profit and revenue probability namely the probability of achieving the profit and revenue targets simultaneously more specifically we analyze a scenario where two competing retailers purchase a perishable product from a common supplier and sell to a common market employing the isoelastic demand model we derive the closed form solutions of the optimal order quantity the optimal selling price and the maximal profit and revenue probability for each retailer it is shown that when revenue is a relevant performance measure positive and non positive salvage values lead to different optima for competing retailers moreover as price elasticity and or price competition intensity becomes higher the optimal retail price decreases and the optimal order quantity increases for each retailer

energy management practices in swedish energy intensive industries previous studies point out a large untapped potential for energy efficiency in industry through the adoption of energy management practices the aim of this paper is to describe and analyze energ

equilibrium capital taxation in open economies under commitment abstract this paper analyzes equilibrium capital taxation in open economies with strategic interaction in a neo classical growth model under perfect commitment i show that non cooperative capital taxes are zero in the long run for a large open economy thereby generalizing the result previously established only for the special cases of a closed and a small open economy this does not represent a race to the bottom though since the result is independent of the degree of capital mobility the number of countries or a country s size relative to the rest of the world moreover when countries cooperate they still set capital taxes to zero in the long run these outcomes are robust to different equilibrium specifications the inclusion of endogenous government spending and heterogeneous agents and non linear labor income taxation governments find it optimal to implement the efficient capital allocation in the long run both in a closed and an open economy this trumps incentives to tax foreigners domestic capital holdings by raising capital taxes and attracting capital from abroad by lowering capital taxes

dynamic optimal taxation in small open economies abstract this paper examines the effects of perfect capital mobility on the determination of optimal capital taxation it shows that capital movements do not change dramatically the optimal tax path studied for the closed economy in addition the paper provides a counterexample to the standard belief that the worldwide system is the optimal regime of taxation finally it shows that the rate of taxation of the rest of the world is not fundamental to determine the optimal decision of a small economy

technical note dynamic pricing and demand learning with limited price experimentation in a dynamic pricing problem where the demand function is not known a priori price experimentation can be used as a demand learning tool existing literature usually assumes no constraint on price changes but in practice sellers often face business constraints that prevent them from conducting extensive experimentation we consider a dynamic pricing model where the demand function is unknown but belongs to a known finite set the seller is allowed to make at most m price changes during t periods the objective is to minimize the worst case regret i e the expected total revenue loss compared with a clairvoyant who knows the demand distribution in advance we demonstrate a pricing policy that incurs a regret of ologmt or m iterations of the logarithm furthermore we describe an implementation of this pricing policy at groupon a large e commerce marketplace for daily deals the field study shows significant impact on revenue and bookings the e companion is available at https doi org 10 1287 opre 2017 1629

dynamic pricing when consumers are strategic analysis of posted and contingent pricing schemes abstract we study dynamic pricing policies for a monopolist selling perishable products over a finite time horizon to strategic buyers buyers are strategic in the sense that they anticipate the firm s price policies it is expensive and administratively difficult for most brick and mortar retailers to change prices placing limits on the number of price changes and the types of pricing policies they can adopt the simplest policy is to commit to a set of price changes a more complex alternative is to let the price depend on sales history we investigate two pricing schemes that we call posted and contingent pricing using the posted pricing scheme the firm announces a set of prices at the beginning of the horizon in the contingent pricing scheme price evolution depends upon demand realization our focus is on the posted pricing scheme because of its ease of implementation counter to intuition we find that neither a posted pricing scheme nor a contingent pricing scheme is dominant and the difference in expected revenues of these two schemes is small limiting the number of price changes will result in a decrease in expected revenues we show that a multi unit auction with a reservation price provides an upper bound for expected revenues for both pricing schemes numerical examples suggest that a posted pricing scheme with two or three price changes is enough to achieve revenues that are close to the upper bound dynamic pricing is only useful when strategic buyers perceive scarcity we study the impact of scarcity and derive the optimal stocking levels for large markets finally we investigate whether or not it is optimal for the seller to conceal inventory or sales information from buyers a firm benefits if it does not reveal the number of units it has available for sale at the beginning of the season or subsequently withholds information about the number of units sold

a fractiles perspective to the joint price quantity newsvendor model pricing and quantity decisions are critical to many firms across different industries we study the joint price quantity newsvendor model where only a single quantity and price decision is made such as a fashion or holiday product that cannot be replenished and where the price is advertised nationally and cannot be changed demand is uncertain and sensitive to price we develop a method for easily finding the optimal price and quantity that applies to more general cases than the usual one in which uncertainty is either additive multiplicative or a combination of the two we represent a quantity by its fractile of the probability distribution of demand for a given price we use a standard approach to approximating a given distribution with a finite number of representative fractiles and assume that these fractile functions are piecewise linear functions of the price we identify effects that are not usually seen in a joint price quantity newsvendor model for example although the optimal quantity is a decreasing function of the unit cost the optimal price can be nonmonotone in the unit cost and we shed insight into why we illustrate that using a simplified structure of demand uncertainty can result in substantially lower profits

who offers tax based business development incentives abstract many american communities seek to attract or retain businesses with tax abatements tax credits or tax increment financing of infrastructure projects tifs the evidence for 1999 indicates that communities are most likely to offer one or more of these business development incentives if their residents have low incomes if they are located close to state borders and if their states have troubled political cultures ten percent greater median household income is associated with a 3 2 lower probability of offering incentives 10 greater distance from a state border is associated with a 1 0 lower probability of offering incentives and a 10 higher rate at which government officials are convicted of federal corruption crimes is associated with a 1 2 greater probability of offering business incentives tifs are the preferred incentive of communities whose residents have household incomes between 25 000 and 75 000 whereas tifs are much less commonly offered by communities whose residents have household incomes below 25 000 the need to finance tifs out of incremental tax revenues may make it infeasible for many of the poorest of communities to use tifs for local business development

perishable asset revenue management with markovian time dependent demand intensities many industries face the problem of selling a fixed stock of items over a finite horizon these industries include airlines selling seats before planes depart hotels renting rooms before midnight theaters selling seats before curtain time and retailers selling seasonal items with long procurement lead times given a sunk investment in seats rooms or winter coats the objective for these industries is to maximize revenues in excess of salvage value when demand is price sensitive and stochastic pricing is an effective tool to maximize expected revenues in this paper we address the problem of deciding the optimal timing of price changes within a given menu of allowable possibly time dependent price paths each of which is associated with a general poisson process with markovian time dependent predictable intensities we show that a set of variational inequalities characterize the value functions and the optimal possibly random time changes in addition we develop an efficient algorithm to compute the optimal value functions and the optimal pricing policy

marketing production decisions in an industrial channel of distribution this paper presents a model that considers the interface between marketing and production decisions in a channel of distribution of industrial goods comprised of a manufacturer and a distributor the key issue investigated is the nature of the coordination within the channel in light of an unstable pattern of seasonal demand the investigation which focuses on dynamic issues considers production activities such as product delivery and inventory policy and their link to marketing strategies such as pricing policies the focus here is on the dynamic nature of the coordinational aspects of the various policies for example the following questions are addressed what is the distributor s pricing strategy throughout the season what is the nature of the contractual price in the channel under what conditions should the distributor carry no inventory throughout the seasonal period under what conditions should the manufacturer carry no inventory what is the impact of the seasonal parameters and differing h

the choice of apportionment factors under formula apportionment thispaperinvestigatesthechoiceofapportionmentfactorsunderacorporatetaxsystemofformulaapportionment in contrast to perceived wisdom we show that the apportionment formula contains both mobile capital and immobile labor factors regardless of whether the formula is determined decentrally by jurisdictions or centrally by a central planner the central planner uses the formula as a corrective instrument to internalize fiscal externalities we calibrate the model to the european union and show that replacing the current system of separate accounting by formula apportionment would substantially increase tax revenue and welfare under both centralized and decentralized formula choices

revenue management with costly price adjustments we consider a novel variant of the perishable inventory profit management problem faced by a firm that sells a fixed inventory over a finite horizon in the presence of price adjustment costs in economics literature such price adjustment costs are widely studied and are typically assumed to include a fixed component e g advertising costs an inventory dependent component e g inventory relabeling costs as well as a component that depends on the magnitude of the price adjustment e g cognitive and coordination managerial costs we formulate the firm s profit management problem as a finite horizon dynamic program in which the state of the system is described by the inventory level as well as the current price level we derive first order properties of the optimal value function and give a complete characterization of optimal policies for the case of ample inventory through a set of examples we demonstrate the complex and counterintuitive nature of optimal price adjustment policies consequently we focus on developing easily computable and implementable heuristics with demonstrably good performance to this end we develop and solve a fluid model based on the original stochastic dynamics and propose three fluid based heuristic policies we derive expressions for the expected profit generated by each one of these heuristics when applied to the stochastic problem and derive sufficient conditions for the asymptotic optimality of the policies when the initial inventory levels and planning horizons are proportionally scaled up we test the performance of the heuristics in a numerical study and demonstrate a robust near optimal performance of one of the heuristics which we call the fluid time heuristic for a wide range of problem parameters finally we demonstrate the importance of proper accounting of price adjustment costs in several alternative business settings

taxation of asset income in the presence of a world securities market abstract this paper examines a capm model of world security prices in which governments recognize their ability to influence international security prices via their tax treatment of foreign and domestic investors in this model governments have the incentive to set tax rates such that investors tend to specialize in domestic securities and to restrict net capital flows between countries each country does this to increase the utility of domestic residents taking as given the tax policies of other governments but the net outcome is a reduction in world efficiency and likely a reduction in the utility of all investors

clearance pricing and inventory policies for retail chains clearance pricing and end of season inventory management are challenging and important problems in retailing sales rates depend upon price seasonal effects and the remaining assortment of items available to customers there is little time to react to observed sales and pricing errors result in either loss of potential revenue or excess inventory to be liquidated this paper develops optimal clearance prices and inventory management policies that take into account the impact of reduced assortment and seasonal changes on sales rates versions of these policies have been tested and implemented at three major retail chains and these applications are summarized and discussed

optimal fiscal and monetary policy in an economy without capital abstract this paper is concerned with the structure and time consistency of optimal fiscal and monetary policy in an economy without capital in a dynamic context optimal taxation means distributing tax distortions over time in a welfare maximizing way for a barter economy our main finding is that with debt commitments of sufficiently rich maturity structure an optimal policy if one exists is time consistent in a monetary economy the idea of optimal taxation must be broadened to include an inflation tax and we find that time consistency does not carry over an optimal inflation tax requires commitment by rules in a sense that has no counterpart in the dynamic theory of ordinary excise taxes the reason time consistency fails in a monetary economy is that nominal assets should from a welfare maximizing point of view always be taxed away via an immediate inflation in a kind of capital levy this emerges as a new possibility when money is introduced into an economy without capital

residence and source based capital taxation in open economies with infinitely lived consumers abstract in this paper we investigate tax competition in a neoclassical growth model where each country may use both residence and source based capital taxes we show that both types of capital taxes are zero at any interior steady state just as in a closed economy for symmetric countries and even for countries that differ only with respect to size and productivity we prove analytically and verify numerically that the open economy policies coincide exactly with the closed economy policies in all time periods for countries that are asymmetric in other dimensions we find that source based taxes are used to manipulate the intertemporal terms of trade in the short run either way the fiscal externalities of source based taxes vanish once residence based taxes are allowed

optimal starting times for end of season sales and optimal stopping times for promotional fares many industries face the problem of selling a fixed stock of items over a finite horizon these industries include airlines selling seats before planes depart hotels renting rooms before midnight theaters selling seats before curtain time and retailers selling seasonal goods such as air conditioners or winter coats before the end of the season given a fixed number of seats rooms or coats the objective for these industries is to maximize revenues in excess of salvage value when demand is price sensitive and stochastic pricing is an effective tool to maximize revenues in this paper we address the problem of deciding the optimal timing of a single price change from a given initial price to either a given lower or higher second price under mild conditions we show that it is optimal to decrease resp to increase the initial price as soon as the time to go falls below resp above a time threshold that depends on the number of yet unsold items

international tax coordination regionalism versus globalism tax competition for mobile capital can undermine the attempts of governments to redistribute income from rich to poor i study whether international tax coordination can alleviate this problem using a general equilibrium model synthesizing recent contributions to the tax competition literature the model highlights the crucial distinction between global tax coordination and regional coordination with high capital mobility between the tax union and the rest of the world the welfare gain from regional capital income tax coordination is only a small fraction of the gain from global coordination even if the tax union is large relative to the world economy

state and local tax competition in a spatial model with sales taxes and residential property taxes abstract this paper presents a theoretical model with a uniformly populated line that is divided into local jurisdictions and or states if one level of government imposes sales and residential property taxes and if the spatial extent of each taxing jurisdiction is positive and finite then in nash equilibrium the sales tax rate is less than residential property tax rate housing consumption is suboptimal and the public good is underprovided in each jurisdiction if a very large state or country is divided into local jurisdictions and if both levels of government choose tax rates endogenously then under some assumptions there is an efficient outcome

effects of constrained supply and price contracts on agricultural cooperatives planning strategies depend in part on the supply flow structure of a supply chain in food supply chains many firms are constrained by raw material supply e g vegetables and milk this paper first examines the economic consequences of constrained supply in agricultural cooperatives secondly it deals with the effects of adding price contracts to the current cooperative contract this model combines an inventory policy approach and a monte carlo simulation to take into account price uncertainty we illustrate our results using the case of a dairy cooperative c 2008 elsevier b v all rights reserved

efficient investment incentives in the presence of capital flight abstract this paper examines the efficiency of quantity restrictions on capital exports and the accompanying set of taxes when a government can effectively tax foreign source income then it is not efficient to impose restrictions on capital exports and the optimal tax rates on foreign source and domestic source income are the same an efficient allocation of domestic savings between foreign and domestic investment is obtained however when the government cannot tax foreign source income it is optimal to impose such a restriction so as to induce overinvestment in domestic capital

an elasticity approach to the newsvendor with price sensitive demand we introduce a measure of elasticity of stochastic demand called the elasticity of the lost sales rate which offers a unifying perspective on the well known newsvendor with pricing problem this new concept provides a framework to characterize structural results for coordinated and uncoordinated pricing and inventory strategies concavity and submodularity of the profit function as well as sensitivity properties of the optimal inventory and price policies are characterized by monotonicity conditions or bounds on the elasticity of the lost sales rate these elasticity conditions are satisfied by most relevant demand models in the marketing and operations literature our results unify and complement previous work on price setting newsvendor models and provide a new tool for researchers modeling stochastic price sensitive demand in other contexts

combined pricing and inventory control under uncertainty this paper addresses the simultaneous determination of pricing and inventory replenishment strategies in the face of demand uncertainty more specifically we analyze the following single item periodic review model demands in consecutive periods are independent but their distributions depend on the item s price in accordance with general stochastic demand functions the price charged in any given period can be specified dynamically as a function of the state of the system a replenishment order may be placed at the beginning of some or all of the periods stockouts are fully backlogged we address both finite and infinite horizon models with the objective of maximizing total expected discounted profit or its time average value assuming that prices can either be adjusted arbitrarily upward or downward or that they can only be decreased we characterize the structure of an optimal combined pricing and inventory strategy for all of the above types of models we also develop an efficient value iteration method to compute these optimal strategies finally we report on an extensive numerical study that characterizes various qualitative properties of the optimal strategies and corresponding optimal profit values

the magnitude of menu costs direct evidence from large u s supermarket chains we use store level data to document the exact process of changing prices and to directly measure menu costs at five multistore supermarket chains we show that changing prices in these establishments is a complex process requiring dozens of steps and a nontrivial amount of resources the menu costs average 105 887 year per store comprising 0 70 percent of revenues 35 2 percent of net margins and 0 52 price change these menu costs may be forming a barrier to price changes specifically 1 a supermarket chain facing higher menu costs due to item pricing laws that require a separate price tag on each item changes prices two and one half times less frequently than the other four chains 2 within this chain the prices of products exempt from the law are changed over three times more frequently than the products subject to the law in principle fixed costs of changing prices can be observed and measured in practice such costs take disparate forms in different firms and we have no data on their magnitude so the theory can be tested at best indirectly at worst not at all alan blinder 1991 p 90

revenue management for low cost providers low cost providers have emerged as important players in many service industries the most predominant being low cost or the so called discount airlines this paper presents models and results leading toward understanding the revenue management outlook for a discount pricing firm a framework and model is formulated specifically for the airline industry but is generalizable to low cost providers in similar revenue management settings we formulate an optimal pricing control model for a firm that must underprice to capture a segment of exogenous demand two specific model formulations are considered a continuous deterministic version and a discrete stochastic version structural results are derived for the deterministic case providing insight into the general form of optimal underpricing policies the stochastic results support the structural insight from the deterministic solution and illuminate the effect of randomness on the underpricing policies

industrial excess heat deliveries to swedish district heating networks drop it like it s hot using industrial excess heat in district heating dh networks reduces the need for primary energy and is considered efficient resource use the conditions of swedish dh markets are under political discussion in the third party access tpa proposal which would facilitate the delivery of firms industrial excess heat to dh networks this paper estimates and discusses the untapped potential for excess heat deliveries to dh networks and considers whether the realization of this potential would be affected by altered dh market conditions the results identify untapped potential for industrial excess heat deliveries and calculations based on estimated investment costs and revenues indicate that realizing the tpa proposal could enable profitable excess heat investments

periodic pricing of seasonal products in retailing this paper studies intertemporal pricing policies when selling seasonal products in retail stores we first present a continuous time model where a seller faces a stochastic arrival of customers with different valuations of the product for this model we characterize the optimal pricing policies as functions of time and inventory we use this model as a benchmark against which we compare more realistic models that consider periodic pricing reviews we show that the structure of the optimal pricing policies in this case is consistent with the procedures observed in practice retail stores successively discount the product during the season and promote a liquidation sale at the end of the planning horizon we also show that the loss experienced when implementing periodic pricing reviews instead of continuous policies is small when the appropriate number of reviews is chosen several interesting economic insights emerge from our analysis for example uncertainty in the demand for new products leads to higher prices larger discounts and more unsold inventory finally we study the effect of announced discount policies on prices and profits we show that stores that have adopted this type of strategy usually set prices such that with high probability the merchandise is sold during the first periods and the largest discounts rarely take place

a pricing model for clearing end of season retail inventory the problem of setting prices for clearing retail inventories of fashion goods is a difficult task that is further exacerbated by the fact that markdowns enacted near the end of the selling season have a smaller impact on demand in this article we present discrete time models for setting clearance prices in such an environment when demand is deterministic we compute optimal prices and show that decreasing reservation prices lead to declining optimal prices when demand is stochastic and arbitrarily correlated across planning periods we obtain bounds on the optimal expected revenue and on optimal prices we also develop a heuristic procedure for finding near optimal prices and test its accuracy through numerical experiments these experiments reveal new insights for practitioners for example the penalty for choosing clearance price once and keeping it unchanged for the remainder of the selling season is found to be small when either the mean reservation prices do not change appreciably over time or when they drop sharply after the first period

a voluntary brain drain tax abstract a major roadblock to the implementation of bhagwati s proposal to allow developing countries to tax skilled emigrants residing in developed countries the brain drain is the administrative problems associated with collecting this tax in the absence of developed country cooperation this paper provides a partial solution to these problems involving the tax treatment of emigrants who return to their countries of origin the tax system is structured so that returning emigrants who previously paid the brain drain tax face lower tax payments than those who evaded the brain drain tax given the expected value of this tax benefit emigrants are willing to pay the brain drain tax in the basic model a source country s optimal tax system includes this brain drain tax and does not distort migration decisions

dynamic pricing in the presence of inventory considerations research overview current practices and future directions the benefits of dynamic pricing methods have long been known in industries such as airlines hotels and electric utilities where the capacity is fixed in the short term and perishable in recent years there has been an increasing adoption of dynamic pricing policies in retail and other industries where the sellers have the ability to store inventory three factors contributed to this phenomenon 1 the increased availability of demand data 2 the ease of changing prices due to new technologies and 3 the availability of decision support tools for analyzing demand data and for dynamic pricing this paper constitutes a review of the literature and current practices in dynamic pricing given its applicability in most markets and its increasing adoption in practice our focus is on dynamic intertemporal pricing in the presence of inventory considerations

capital income taxation in a growing open economy abstract the paper studies the dynamic macroeconomic effects of various forms of capital income taxation in a model of a small open economy with perfect mobility of financial capital and intertemporal optimization on the part of households and firms one of the noteworthy results is that the introduction of a low corporate income tax will not affect consumption in the long run but will simply lead to a replacement of shares by foreign financial assets in household portfolios it is also found that an anticipated investment tax credit can have and that an anticipated dividend tax will have contractionary effects on investment before they are introduced moreover it is shown that while an unanticipated dividend tax is neutral with respect to investment it will have real effects on consumption and net foreign assets in a growing economy

a three input model of the spatial effects of a central city wage tax abstract this paper considers the short run and long run spatial effects on wages employment and business capital as functions of location of a localized increase in wage tax rates the model is most applicable to a central city that has a higher wage tax rate than the surrounding suburbs the inclusion of land as a third input in production significantly reduces the long run effects of a central city wage tax on employment near the central city boundary as compared with a model in which labor and capital are the only two inputs the short run effects are significantly less than the long run effects

list pricing versus dynamic pricing impact on the revenue risk abstract we consider the problem of a firm selling multiple products that consume a single resource over a finite time period the amount of the resource is exogenously fixed we analyze the difference between a dynamic pricing policy and a list price capacity control policy the dynamic pricing policy adjusts prices steadily resolving the underlying problem every time step whereas the list pricing policy sets static prices once but controls the capacity by allowing or preventing product sales as steady price changes are often costly or unachievable in practice we investigate the question of how much riskier it is to apply a list pricing policy rather than a dynamic pricing policy we conduct several numerical experiments and compare expected revenue standard deviation and conditional value at risk between the pricing policies the differences between the policies show that list pricing can be a useful strategy when dynamic pricing is costly or impractical

the direct incidence of corporate income tax on wages a stylised model is provided to show how the direct effect of corporate income tax on wages can be identified in a bargaining framework using cross company variation in tax liabilities conditional on value added per employee using data on 55 082 companies located in nine european countries over the period 1996 2003 we estimate the long run elasticity of the wage bill with respect to taxation to be 0 093 evaluated at the mean this implies that an exogenous rise of 1 in tax would reduce the wage bill by 49 cents only a weak evidence of a difference for multinational companies is found

on the efficiency and equity trade off abstract the concept of policy measures that create a potential pareto improvement has dominated normative economics the use of this concept in welfare economics relies on the availability of discriminatory lump sum transfers in such a way that the implementation of the efficient policy measure leads to a pareto movement in the economy however most studies of efficient policies preclude by assumption the existence of lump sum taxation this paper proposes in economies amenable to gorman aggregation one simple methodology to rank alternative allocations in terms of their distributional implications in a world with no lump sum transfers this methodology is simple because it is independent of the distribution of characteristics in the economy then for a specific policy measure it can be easily identified whether it implies an equity efficiency trade off the method is illustrated by analyzing the effects on inequality of the elimination of capital taxation the reduction of the inflation tax and the liberalization of capital movements in a small open economy

taxation and inflation a new explanation for capital flows abstract in a world of mobile capital the current system of taxation implies that the after tax cost of capital and return to saving in each country are negatively correlated with the rate of inflation thus a country s net foreign asset position ought to be negatively correlated with its long run inflation rate the magnitude of these effects is shown to be potentially large for oecd countries cross section and time series regressions confirm that inflation rates are good predictors of net foreign assets the existing distribution of net foreign assets may therefore largely reflect tax distortions

chapter 11 pricing models in marketing publisher summary this chapter brings together a set of diverse efforts in the recent literature on the modeling of price decisions and related questions in marketing there has been an impressive growth in the array of topics investigated in the literature various trends in the development of pricing models are evident from the foregoing review first one trend has been to develop theoretical models to describe observed pricing strategies in the marketplace and to derive conditions under which certain strategies are optimal this trend is clearly evident when one considers the area of dynamic pricing models another trend is an attempt to develop pricing models in which certain aspects of consumer behavior e g asymmetric response to price increases versus price decreases are incorporated this development is quite recent and does offer a large potential a third dominant direction is the use of game theoretic models for developing equilibrium pricing strategies

should capital income be taxed in the steady state this paper provides a new economic interpretation of the well known dynamic optimal taxation principle that capital income should not be taxed in the steady state we show that the result is related to the minimization of distortions at the intratemporal margin when every factor of production can be taxed at the optimal rate capital income should not be taxed in the steady state but when there are restrictions on the taxation of production factors the tax rate on capital income in the steady state is different from zero

an optimal taxation approach to fiscal federalism in a federal system of government each unit of government decides independently how much of each type of public good to provide and what types of taxes and which tax rates to use in funding the public goods in this paper we explore what types of problems can arise from this decentralized form of decision making in particular we describe systematically the types of externalities that one unit of government can create for nonresidents through both its public goods decisions and its taxation decisions the paper also explores briefly what the central government might do to lessen the costs of decentralized decision making

hypergrowth in an east asian nic public policy and capital accumulation in singapore abstract singapore has produced the world s highest investment ratios known to account for growth more rapid than in any other less developed country over the past three decades but such high investment needs explanation we trace singapore s public policy of increasing tax concessions and infrastructural spending in effect subsidies to private firms and use an open economy neoclassical model to show how by attracting footloose foreign capital and raising investment levels these policy measures can drive growth the consequent transformation of living standards in singapore suggests in accordance with theory but contrary to most practice that for some less developed countries effectively zero tax on foreign direct investment may be a beneficial strategy yet for both singapore and other would be late industrializers major issues of development strategy arise from the kind of input driven growth analyzed in this article

optimal taxation of capital income in general equilibrium with infinite lives this paper analyzes the optimal tax on capital income in general equilibrium models of the second best agents have infinite lives and utility functions which are extensions from the koopmans form the population is heterogeneous the important property of the models is the equality between the social and the private discount rates in the long run i find that the optimal tax rate is zero in the long run for a special case of additively separable utility functions i then determine the tax rates along the dynamic path and conditions that are sufficient for the local stability of the steady state

international tax competition and gains from tax harmonization abstract in a world economy there are two types of distortions which can be caused by capital income taxation in addition to the standard closed economy wedge between the consumer saver marginal intertemporal rate of substitution and the producer investor marginal productivity of capital i international differences in intertemporal marginal rates of substitution implying an inefficient allocation of world savings across countries and ii international differences in the marginal productivity of capital implying an inefficient allocation of world investment across countries the paper focuses on the structure of taxation for countries which are engaged in tax competition and on potential gains from a tax harmonization we show that if the competing countries are sufficiently coordinated with the rest of the world then tax competition leads each country to apply the residence principle of taxation and there are no gains from tax harmonization if however there is not sufficient coordination then tax competition leads to low capital income taxes and the tax burden falls on the internationally immobile factors the outcome is nevertheless still efficient relative to the available constrained set of tax instruments

economic freedom and taxation is there a trade off in the locational competition between countries this paper investigates the relationshipbetween economic freedomand taxation we argue that an economicallyfree environment improvesthe attractiveness of a location which inturn enables governmentsto levy higher business taxes to test thishypothesis empirically weestimate the impact of economic freedom onthe national tax policy where the latter is measured by thecorporate tax revenue related tognp corporate tax ratio we utilize adata set of 46 developed and lessdeveloped countries between 1980 and 1997and find a clear confirmationof our hypothesis further a simulationanalysis reveals that the observedchange in economic freedom has equalizedthe international distributionof corporate tax ratios

trade capital mobility and tax competition this paper examines a system of governments national state or local that finance public expenditures with taxes on mobile capital e g a property tax unlike previous research on tax competition explicit consideration is given to the general equilibrium determination of the prices at which goods are traded between regions the analysis identifies inefficiencies in government behavior that are not apparent in models in which the terms of trade are exogenously given capital taxation is shown to create an inefficient distribution of public good outputs across regions accompanied by an inefficient pattern of trade a model is presented in which the chosen levels of public good outputs differ across regions containing identical residents and production possibilities there is a wasteful diversity of public good supplies

factor income taxation and growth with increasing integration of world capital markets abstract in a closed economy the infinite horizon and the overlapping generations og model prescribe diametrically opposite policies on factor taxation the former argues that the growth maximizing capital income tax rate should be set to zero whereas the latter argues that it should be set as high as possible this note investigates the issue by taking into account global capital market integration we show that the long run growth maximizing capital income tax rate in a small open og economy is decreasing as the economy s capital market is increasingly integrated with the rest of the world and will be equal to zero as prescribed in the infinite horizon model once the degree of integration becomes sufficiently high

the impact of dynamic pricing on the economic order decision this paper analyzes the impact of dynamic pricing on the single product economic order decision of a monopolist retailer items are procured from an external supplier according to the economic order quantity eoq model and are sold to customers on a single market without competition following the simple monopolist pricing problem coordinated decision making of optimal pricing and ordering is influenced by operating costs including ordering and inventory holding costs and the demand rate obtained from a price response function the retailer is allowed to vary the selling price either in a fixed number of discrete points in time or continuously while constant and continuous pricing have received much attention in the literature problems with a limited number of price changes are rather rare this paper illustrates the benefit of dynamically changing prices to achieve operational efficiency in the eoq model that is to trigger high demand rates when inventories are high we provide structural properties of the optimal time instants when the price should be changed taking into account costs for changes in price it provides numerical guidance on number timing and size of price changes during an order cycle numerical examples show that the benefits of dynamic pricing in an eoq framework can be achieved with only a few price changes and that products being unprofitable under static pricing may become profitable under dynamic pricing

tax competition tax exporting and higher government choice of tax instruments for local governments abstract this paper presents a theoretical model with tax exporting due to external ownership of a fraction of the land in each local jurisdiction there are n local jurisdictions in a metropolitan area n 1 and many metropolitan areas in a world economy the paper examines the usage of business property taxes and source based wage taxes by local jurisdictions first in the presence of and then in the absence of residence based lump sum taxes and how this depends on and n the paper then examines the choice of a world national or state government as to whether to allow local metropolitan or sub metropolitan governments to use business property taxes wage taxes or both assuming that the local governments choose the actual tax rates

do credible domestic institutions promote credible international agreements we examine the relationship between international policy coordination and domestic policy reputation when both are self sustaining we show that domestic policy commitment does not necessarily facilitate international cooperation rather efficient policies may be most easily sustained when governments are unable to pre commit to policy domestically moreover the lack of domestic commitment is more likely to facilitate international cooperation the larger the international spillovers of domestic policies are

taxation of investment and savings in a world economy the equilibrium of capital and equilibrium market prices are derived for a world economy with a unified securities market mobile capital no uncertainty and varying tax rates on different sources of income in each country the paper then characterizes optimal tax rates for a small country in this setting focusing on the peculiar incentives created when the before tax rate of return differs among securities due to differences in their typical tax treatment copyright 1986 by american economic association

a partially observed markov decision process for dynamic pricing in this paper we develop a stylized partially observed markov decision process pomdp framework to study a dynamic pricing problem faced by sellers of fashion like goods we consider a retailer that plans to sell a given stock of items during a finite sales season the objective of the retailer is to dynamically price the product in a way that maximizes expected revenues our model brings together various types of uncertainties about the demand some of which are resolvable through sales observations we develop a rigorous upper bound for the seller s optimal dynamic decision problem and use it to propose an active learning heuristic pricing policy we conduct a numerical study to test the performance of four different heuristic dynamic pricing policies in order to gain insight into several important managerial questions that arise in the context of revenue management

tax competition with parasitic tax havens we develop a tax competition framework in which some jurisdictions called tax havens are parasitic on the revenues of other countries the havens use real resources to help companies camouflage their home country tax avoidance and countries use resources in an attempt to limit the transfer of tax revenues to the havens the equilibrium price for this service depends on the demand and supply for such protection recognizing that taxes on wage income are also evaded we solve for the equilibrium tax rates on mobile capital and immobile labor and we demonstrate that the full or partial elimination of tax havens would improve welfare in non haven countries in part because countries would be induced to increase their tax rates which they have set at inefficiently low levels in an attempt to attract mobile capital we also demonstrate that the smaller countries choose to become tax havens and we show that the abolishment of a sufficiently small number of the relatively large havens leaves all countries better off including the remaining havens

dynamic pricing and ordering decisions by a monopolist this paper considers the relationship between pricing and ordering decisions for a monopolistic retailer facing a known demand function where over the inventory cycle the product may exhibit i physical decay or deterioration of inventory called wastage and ii decrease in market value called value drop associated with each unit of inventory on hand the retailer is allowed to continuously vary the selling price of the product over the cycle we introduce a notion of instantaneous margin and use it to derive profit maximizing conditions for the retailer the model explains the markdown of retail goods subject to decay it also provides guidance in determining when price changes during the cycle are worthwhile due to product aging how often such changes should be made and how such changes affect ordering intervals and quantities
