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

taxation of outbound direct investment economic principles and tax policy considerations this paper reviews economic principles for optimality of the taxation of international profit from both a global and national perspective it argues that for traditional systems based on the residence of the investor or the source of the income nothing less than full harmonisation across countries can achieve global optimality the conditions for national optimality are more difficult to identify but are most likely to imply source based taxation however source based taxation requires an allocation of the profits of multinational companies to individual jurisdictions this is not only very difficult in practice but in some cases is without any conceptual foundation the taxation of interest income on a residence basis is also hard to justify if the aim of the tax system is to tax only the income arising from economic activity in a given country

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

optimality properties of alternative systems of taxation of foreign capital income foreign source capital income taxes are examined from the point of view of optimal taxation in the framework of a simple economy with international real capital flows a taxonomy of alternative systems of such taxation is first presented showing how crediting and other tax parameters induce what are called source based residence based and related systems next tax rates are determined that are optimal from a single country s point of view given those of the others the achievability of these rates under the various systems is analyzed finally tax rates that are optimal from an international point of view are considered again achievability of an international optimum under the various systems is considered leading to the main conclusions that i a pure residence based system in all countries can achieve an international fiscal optimum ii it cannot however be sustained as an equilibrium

home bias and cross border taxation abstract the relationship between cross border taxation and free float home bias is examined this explicitly recognizes that insider shares are unavailable to foreigners other important explanations for home bias information asymmetry behavioural and governance issues are controlled when examining the impact of cross border tax variables in our sample of countries about sixty percent eighty percent withhold taxes on realized capital gains dividends of foreign investors and about thirty percent of the mature economies provide imputation of taxes paid on dividend income by domestic corporations dividend imputation is a statistically significant impediment to cross border equity flows a tax credit variable for foreign taxes paid on dividends is constructed and found to be statistically significant in reducing home bias a relatively high foreign tax rate that cannot be offset by tax credits is found to significantly increase home bias these results hold for float adjusted home bias and traditional international portfolio home bias

accounting for asymmetric price responses and underlying energy demand trends in oecd industrial energy demand abstract this paper explores the way technical progress and improvements in energy efficiency are captured when modelling oecd industrial energy demand the industrial sectors of the developed world involve a number of different practices and processes utilising a range of different technologies consequently given the derived demand nature of energy it is vital when modelling industrial energy demand that the impact of technical progress is appropriately captured however the energy economics literature does not give a clear guide on how this can be achieved one strand suggests that technical progress is endogenous via asymmetric price responses whereas another strand suggests that it is exogenous more recently it has been suggested that potentially there is a role for both endogenous technical progress and exogenous technical progress and consequently the general model should be specified accordingly this paper therefore attempts to model oecd industrial energy demand using annual time series data over the period 1962 2010 for 15 oecd countries using the structural time series model framework the general specifications allow for both asymmetric price responses for technical progress to impact endogenously and an underlying energy demand trend for technical progress and other factors to impact exogenously but in a non linear way the results show that almost all of the preferred models for oecd industrial energy demand incorporate both a stochastic underlying energy demand trend and asymmetric price responses this gives estimated long run income elasticities in the range of 0 34 to 0 96 estimated long run price maximum elasticities in the range of 0 06 to 1 22 estimated long run price recovery elasticities in the range of 0 00 to 0 27 and estimated long run price cut elasticities in the range of 0 00 to 0 18 furthermore the analysis suggests that when modelling industrial energy demand there is a place for endogenous technical progress and an exogenous underlying energy demand trend consequently it is argued that any modelling strategy should start by including both and only imposed restrictions if accepted by the data

primary energy demand in japan an empirical analysis of long term trends and future co2 emissions abstract this paper examines the long run relationship between energy demand gnp and the real energy price in japan using data covering 1887 2001 it is found that if an underlying energy demand trend is appropriately incorporated the resulting econometric model produces a long run income elasticity of about unity and a long run price elasticity of about 0 2 the estimated model is utilised to forecast energy consumption and co 2 emissions up to 2012 it is shown that given current economic conditions and policies there is considerable uncertainty about whether japan will be able to meet its kyoto target by reducing co 2 emissions in 2008 2012 to the 1990 level it is shown that this uncertainty depends on the strength of the economy and leaves the japanese government with a difficult policy dilemma if there is a resurgence in growth to something near the annual average growth rate since the early 1980s a considerable effort will be required in order to meet its kyoto target requiring not only using the kyoto mechanisms but also additional tougher domestic policies and measures such as emissions capping r d incentives and education for energy conservation in addition to a pricing and tax policy

price discrimination in the airline market the effect of market concentration we test the hypothesis that price discrimination increases with competition in the airline market using a large cross section of tickets offered by several carriers on various routes we approximate price discrimination with marginal implicit prices of ticket restrictions that carriers typically use to price discriminate saturday night stayover re quirements and advanced purchase discounts we find that the restrictions are associated with lower airfares but that the discounts are smaller on routes with higher market concentration the results suggest that price dispersion attributed to ticket restrictions increases as markets becomemore competitive

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

demand elasticity estimates for new zealand tourism demand elasticities for new zealand tourism are estimated for 16 different international visitor segments segments are differentiated by origin purpose of visit and travel style elasticities for both international visitor arrivals and on the ground expenditure per arrival are estimated for each segment using time series data in general on the ground consumption per arrival is more price sensitive than number of arrivals and asian market segments are found to be more price sensitive both in terms of arrivals and on the ground expenditure compared to international visitors from other regions an application of the results is presented giving the total effect of exchange rate changes on expenditure by international visitors in new zealand and management implications are discussed

a general proposition on the design of a neutral business tax abstract a simple and general means of levying a business tax that is neutral in the sense that it does not affect the firm s decisions at the margin is discussed in particular we analyze the effect of a business tax of our design on the investment decision of the firm the well known imputed income and immediate write off methods of levying a neutral business tax are found to be special cases of our general tax design the implication of our results is that a neutral pure profits tax can be levied without the informational difficulties of the imputed income method or the cash flow disadvantages of the immediate write off method

on the design of a neutral business tax under uncertainty this paper extends the results of boadway and bruce journal of public economics 1984 24 231 239 and fane journal of public economics 1987 33 95 105 to describe a tax on business profits which is neutral with respect to investment and wind up decisions and default outcomes under uncertainty and bankruptcy risk the tax base allows deductions for depreciation and the cost of finance but requires knowledge of neither true economic depreciation nor the firm s required rate of return we show that the tax must treat taxable profits and losses symmetrically and that the tax rate must be a known constant even in the special case when the tax base coincides with the economic rent earned in each period

treasury i and the tax reform act of 1986 the economics and politics of tax reform abstract during president reagan s state of the union address in january 1984 he requested that treasury secretary donald regan prepare a plan for action to simplify the entire tax code so that all taxpayers big and small are treated more fairly in response the department of the treasury spent ten months preparing a report to the president that has come to be called treasury i this three volume study explained the need for tax reform and the general directions such reform should take provided a comprehensive set of proposals for reform of the income tax and analyzed the feasibility and desirability of an american value added tax following almost two years of public debate the tax reform act of 1986 became law on october 22 1986 though widely hailed as the most far reaching reform of the nation s tax system since the 1940s the 1986 act falls far short of the promise of treasury i it is useful to devote attention to treasury i even though much of it failed to survive the legislative process

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

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

multinationals and industrial policy are there benefits to the host country from multinational investments does potential value from these investments make active industrial policy worthwhile we answer the first question affirmatively having reviewed economic principles and evidence concerning the effects of projects locating in or not being off shored from a country on the second policy can have a limited effect in influencing location decisions but it is doubtful that it is cost effective implementation faces lack of information risk of capture and in many cases non rigorous processes competition between jurisdictions means that much policy is investment diversion not investment creation there is a case for supra national controls as with eu state aid regulations for policy to be used only for well defined market failures and for better implementation and more rigorous ex ante appraisal and ex post evaluation copyright 2013 oxford university press

has ryanair s pricing strategy changed over time an empirical analysis of its 2006 2007 flights abstract this paper analyzes the question of whether ryanair s pricing strategies have changed over time we create a panel dataset of fares for all of ryanair s european flights over a two year period from 1 january 2006 to 31 december 2007 we calculate the average fare over a 90 day period prior to departure and the intensity of dynamic pricing for each flight in the panel in particular analysing the changes in these variables observed between pairs of equivalent flights our results show that overall both average fares and the intensity of dynamic pricing decreased in 2007 more than one third of flights saw a price reduction of more than 10 now that it has become the dominant low cost carrier in europe ryanair appears to be softening its dynamic pricing activities on existing routes typically employed to stimulate additional touristic demand thus booking in advance becomes relatively more expensive

business taxation in a globalized world this paper addresses broad issues concerning taxes on company profit in a globalized world in which companies capital and profit can move easily between countries it considers reasons for national taxation of company profit in such a world and reviews the development of such taxes in the oecd the role played by tax havens is discussed and evidence on the responsiveness of companies to differences in taxation across countries is presented a central issue is the allocation of taxable profit between countries existing practice has no clear rationale recent proposals for fundamental reform in the eu are discussed

simple rules for the optimal taxation of international capital income in this paper we reconcile and extend previous results on the collectively optimal taxation of international investment income the weighted average rule of horst 1980 for example is shown to rest on unattractive assumptions on the set of instruments available ruling out any need for distorting taxes the principal contribution is to establish a new and strikingly simple weighted average rule encompassing the other key result in this area for the general case in which lump sum taxes are unavailable the ability to tax pure profits is perhaps restricted and distorting taxes on both domestic and border crossing capital income are optimally deployed

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

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

asymmetric price responses and the underlying energy demand trend are they substitutes or complements evidence from modelling oecd aggregate energy demand abstract a number of energy demand studies have considered the importance of modelling asymmetric price responses apr for example the often cited work of gately and huntington 2002 griffin and schulman 2005 questioned the asymmetric approach arguing that this is only capturing energy saving technical progress huntington 2006 however showed that for whole economy aggregate energy and oil demand there is a role statistically for both apr and exogenous energy saving technical change in a separate strand of the literature the idea of the underlying energy demand trend uedt has been developed see for example hunt et al 2003a and 2003b and dimitropoulos et al 2005 they argue that it is important in time series energy demand models to allow for stochastic trends or uedts based upon the structural time series dynamic regression methodology recommended by harvey 1989 1997 this paper attempts to bring these strands of the literature together by proposing a testing procedure for the uedt and apr in energy demand models within both a panel context consistent with the huntington 2006 approach and the structural time series modelling framework a set of tests across a range of specifications using time series and panel data are therefore suggested in order to try and ascertain whether energy saving technical change or the more general uedt and apr are substitutes for each other when modelling energy demand or whether they are actually picking up different influences and are therefore complements using annual whole economy data for 17 oecd countries over the period 1960 2006 the results suggest that for most of the countries the uedt is preferred to apr whereas for another group the uedt and apr are complements and for another group they are substitutes it is argued therefore that energy demand modellers should not assume at the outset that one method is superior to the other moreover wherever possible a general model be it in a time series or panel context that includes a non linear uedt and apr should be initially estimated and only if accepted by the data should symmetry and or a more restrictive uedt be imposed

dynamic pricing advance sales and aggregate demand learning in airlines this paper uses a unique u s airlines panel data set to empirically study the dynamic pricing of inventories with uncertain demand over a finite horizon i estimate a dynamic pricing equation and a dynamic demand equation that jointly characterize the adjustment process between prices and sales as the flight date nears i find that the price increases as the inventory decreases and decreases as there is less time to sell consistent with aggregate demand learning and price adjustment demand shocks have a positive and much larger effect on prices than the positive effect of anticipated sales

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

examining the role of energy efficiency and non economic factors in energy demand and co2 emissions in nigeria policy implications abstract this paper examines the role of energy efficiency and non economic factors such as consumers preferences lifestyles and values which have hitherto been ignored in energy demand and co2 emissions modelling for nigeria we use a structural time series model to estimate various energy demand and co2 intensity models that take account of the aforementioned factors we adopt preferred models from these estimates to analyse how energy demand and co2 emissions in nigeria might evolve by generating three different future scenarios to 2025 we find energy efficiency and non economic factors to influence energy demand and co2 emissions the long run income and price elasticities obtained differ significantly from those in existing studies that have ignored these salient factors in a business as usual scenario the results indicate that energy demand will continue to grow consequently present policies do not sufficiently mitigate aggregate co2 emissions in nigeria the lesson for policy makers is that the extant policies introduced to restrain co2 emissions from a production perspective have to be combined with new policies that influence consumers lifestyles and behaviours develop energy efficient technologies and apply low tariffs on imported energy efficient appliances to drive down co2 emissions from a consumption perspective

generalised r based and s based taxes under uncertainty this paper considers the relationship between two general neutral business tax structures which we label the firm tax and the shareholder tax the well known r based and s based cash flow taxes analysed by meade 1978 are special cases of these two taxes we demonstrate the neutrality of both taxes in the presence of uncertainty and characterise the tax rules required in the event of default and wind up our analysis provides the first proof of the neutrality of the s based cash flow tax and the allowance for corporate equity ace corporation tax under uncertainty we also discuss implementation and tax avoidance issues

new empirical generalizations on the determinants of price elasticity abstract the importance of pricing decisions for firms has fueled an extensive stream of research on price elasticities in an influential meta analytical study tellis 1988 summarized price elasticity research findings until 1986 however empirical generalizations on price elasticity require modifications because of 1 changes in market characteristics i e characteristics of brands product categories and economic conditions and 2 changes in the research methodology used to assess price elasticities therefore the authors present a meta analysis of price elasticity with new empirical generalizations on its determinants across a set of 1851 price elasticities based on 81 studies the average price elasticity is 2 62 a salient finding is that over the past four decades sales elasticities have significantly increased in magnitude whereas share and choice elasticities have remained fairly constant the authors find that accommodating price endogeneity has a strong magnitude increasing impa

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

multi dimensional price elasticity for leisure and business destinations in the low cost air transport market evidence from easyjet this study investigates the price elasticity of demand in the european low cost carrier lcc industry by analysing internet fares for all easyjet flights departing from the amsterdam schiphol airport towards 21 european destinations between march and september 2015 results suggest that the price elasticity of demand greatly varies across different dimensions ranging from 0 535 for the business oriented route of hamburg to 1 915 for the leisure oriented route of split price elasticity is also found to be higher for reservations made more days in advance for reservations and departures occurring on weekends and for flights taking off during lunchtime and in the summer period all results are consistent with the different behaviours of leisure and business passengers and the ongoing increase in the business component of the lcc passenger mix

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

quantifying the impact of exogenous non economic factors on uk transport oil demand abstract this paper attempts to quantify the impact of exogenous non economic factors on uk transport oil demand in addition to income price and fuel efficiency by estimating the demand relationship for oil transport for 1960 2007 using the structural time series model from this the relative impact on uk transport oil demand from income price and efficiency are quantified moreover the relative impact of the non economic factors is also quantified based on the premise that the estimated stochastic trend represents behavioural responses to changes in socio economic factors and changes in lifestyles and attitudes the estimated elasticities for income price and efficiency are 0 6 0 1 and 0 3 respectively and it is shown that for efficiency and price the overall contribution is relatively small whereas the contribution from income and non economic factors is relatively large this has important implications for policy makers keen to reduce transport oil consumption and associated emissions but not willing to reduce the trend rate of economic growth taxes and improved efficiency only have a limited impact hence a major thrust of policy should perhaps be on educating and informing consumers to persuade them to change their lifestyle and attitudes and thus reduce their consumption through the non economic instruments route

why do all the flights leave at 8 am competition and departure time differentiation in airline markets abstract theoretical models of spatial product differentiation indicate that firms face two opposing incentives 1 minimize differentiation in order to steal customers from competitors and 2 maximize differentiation in order to reduce price competition using data on u s airline departure times from 1975 when fares were regulated and 1986 when fares were not regulated we empirically estimate the effect of competition on differentiation we find a negative relationship in both periods in 1986 however reductions in exogenous scheduling constraints increase differentiation implying that firms may be differentiating their products where possible to reduce price competition this effect is not apparent in the 1975 data

diagnostic checking of unobserved components time series models diagnostic checking of the specification of time series models is normally carried out using the innovations that is the one step ahead prediction errors in an unobserved components model other sets of residuals are available these auxiliary residuals are estimators of the disturbances associated with the unobserved components they can often yield information that is less apparent from the innovations but they suffer from the disadvantage that they are serially correlated even in a correctly specified model with known parameters this article shows how the properties of the auxiliary residuals may be obtained how they are related to each other and to the innovations and how they can be used to construct test statistics applications are presented showing how residuals can be used to detect and distinguish between outliers and structural change

underlying trends and seasonality in uk energy demand a sectoral analysis this paper demonstrates the importance for energy demand modelling of allowing for trends and seasonal effects that are stochastic in form inherent underlying trends may be non linear and reflect not only technical progress which usually produces greater energy efficiency but also other factors such as changes in consumer tastes and the economic structure that may be working in the opposite direction using quarterly unadjusted data for various sectors in the uk it is shown that unless energy demand models are formulated so as to allow for stochastic trends and seasonals estimates of price and income elasticities could be seriously biased

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

prices prices and prices a study in the airline sector abstract this article creates and empirically analyzes a dynamic pricing framework the model includes the main theories on prices in the literature and dynamically analyzes how companies change their pricing policies according to different circumstances through the use of regressions the article shows the relative long and short term impact on pricing equations strategic versus operational matters and on production conditions versus demand perspectives in the setting of operational prices in addition it highlights how the proportions of these pricing perspectives change in the airline sector according to the effect of the environment on the configuration of the strategy determined by monthly and hourly seasonality and also according to the nature of this competitive strategy determined by the characteristics of the company and the destination airport the results confirm our framework and show how firms combine the different perspectives in their pricing strategies

taxation uncertainty and the choice of a consumption tax base abstract several observers have concluded that the equivalence between the cash flow and wage tax approaches to direct consumption taxation breaks down in the presence of uncertainty as individuals with extraordinarily large gains are treated too generously under the latter approach in particular ahsan journal of public economics 1989 40 99 134 canadian journal of economics 1990 23 408 433 contends that equivalence obtains only if returns in excess of a safe rate of return are included in the wage tax base this paper constructs an alternative and arguably more plausible model under which full equivalence between the two approaches obtains even in the presence of uncertainty it also derives ahsan s result in a more general context and demonstrates that the divergence between the two analyses is attributable to different assumptions regarding the cost to the government of an uncertain revenue stream

equilibrium price dispersion under demand uncertainty the roles of costly capacity and market structure when capacity is costly and prices are set in advance firms facing uncertain demand will sell output at multiple prices and limit the quantity available at each price i show that the optimal price strategy of a monopolist and the unique pure strategy nash equilibria of oligopolists both exhibit intrafirm price dispersion moreover as the market becomes more competitive prices become more dispersed a pattern documented in the airline industry while generating similar predictions the model differs from the revenue management literature because it disregards market segmentation and fare restrictions that screen customers

low cost pricing strategies in leisure markets abstract the practice of dynamic pricing typical of low cost carriers is generally regarded as a form of price discrimination between leisure and business travellers on a single flight or route the same may not be true across different routes because of the different incidence of business travellers if price increases in the 15 days prior to departure are meant to discriminate business demand leisure demand should account for earlier price variations in the present study we used a database containing the daily fare over the 3 months prior to each flight operated by easyjet during 2009 for each route we defined the leisure index as the difference between the price rates of change during the 90 days and 15 days prior to departure overall business routes had lower average prices per km while leisure routes showed less dynamic price behaviour with higher minimum and lower maximum prices per km

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

a taxonomy and research overview of perishable asset revenue management yield management overbooking and pricing this paper proposes the term perishable asset revenue management to denote the field that combines the areas of yield management overbooking and pricing for perishable assets after summarizing the characteristics common to problems in this field the paper discusses the objectives and constraints faced by decision makers then it offers a comprehensive taxonomy with 14 different elements and reviews the research that has been done related to each element finally it suggests some important areas of future research that can help bridge the gap between theory and application

estimating petroleum products demand elasticities in nigeria a multivariate cointegration approach this paper formulates and estimates petroleum products demand functions in nigeria at both aggregative and product level for the period 1977 to 2006 using multivariate cointegration approach the estimated short and long run price and income elasticities confirm conventional wisdom that energy consumption responds positively to changes in gdp and negatively to changes in energy price however the price and income elasticities of demand varied according to product type kerosene and gasoline have relatively high short run income and price elasticities compared to diesel overall the results show petroleum products to be price and income inelastic

what students remember and say about college economics years later in his presidential address to the american economic association george stigler 1963 offered the provocative hypothesis that students would retain very little knowledge from principles courses in economics five years or more after taking the courses the few empirical studies that have been published on this topic generally found no or small lasting effects at least for those who took fewer than four courses see e g g l bach and phillip saunders 1965 gerald j lynch 1990 that raises even broader questions about the long term effects of studying economics in college in terms of individuals behavior as consumers workers and voters which we are now beginning to investigate using both survey and transcript data we have two major goals in this study first we want to learn how students perceive their classroom experience in economics courses years after leaving school both in absolute terms and compared to other courses they took we drew samples of economics business and other majors who attended our four universities in 1976 1986 and 1996 and asked which topics regularly covered in economics courses they now viewed as being most and least important we asked whether they now viewed the economics courses they took as interesting important too difficult or too abstract we also compared their perceptions of teaching methods and grading rigor in economics courses to those developed in other courses our second major goal represents an empirical test of the common claim that economics is a unique way of thinking if it is we might reasonably expect people with more training in economics to have different views on policy issues and to make different decisions as consumers workers savers investors and voters we collected survey data on many of these choices and by matching those responses with transcript data we plan to investigate whether there are observable behavioral responses associated with being an economics major or simply taking some minimum number of economics courses compared to students who took fewer courses or none at all there are other uses for these data they can likely be used to study choice of major and course taking behavior as well as common laboreconomics issues such as human capital versus screening in the labor market certainly the data can provide insight into curriculum development for economics departments and business schools as well there is obviously the potential for response biases in the analysis of these data but we expect that having transcript data for respondents and nonrespondents will allow us to deal with these issues econometrically this first brief report from this ongoing project addresses only the first goal of the project specifically how our former students evaluate their experience with economics courses and instructors what economic courses and concepts do they now believe are most important do they wish they had taken more or less coursework in economics what do they think now about various economic issues and allgood department of economics university of nebraska lincoln ne 68588 e mail sallgood unlnotes unl edu bosshardt department of economics florida atlantic university boca raton fl 33431 e mail wbosshar fau edu van der klaauw department of economics university of north carolina chapel hill nc 27599 e mail vanderkl email unc edu watts department of economics purdue university west lafayette in 47907 and while this paper was written the german international school of management and administration hanover germany e mail mwatts mgmt purdue edu we thank the board of the calvin k kazanjian economics foundation for the grant that made this work possible and the aea committee for economic education for bringing us together to write the proposal as described in michael salemi et al 2002 mike salemi provided helpful comments on an earlier draft of this paper april fidler provided major assistance in project coordination administration and data entry georg schaur worked extensively with data organization and preliminary tabulations

energy consumption and economic activity in industrialized countries the dynamic aggregate time series relationship abstract most econometric studies suggest that the income elasticity of demand for energy is approximately unity for the developed market economies it is shown that over the period 1950 1978 the long run income elasticity is substantially higher than unity in terms of a ces energy demand function this result reflects the application of a generalized dynamic estimation methodology where serial correlation is regarded as a diagnostic guide to distributed lag fitting price elasticities are also estimated but these are in line with conventional estimates

european tax harmonisation and production efficiency this paper analyses the impact on production efficiency of potential harmonisation of the taxation of income from capital in the european union it develops and applies a methodology for computing the cost of capital for transnational investments to assess the degree to which production efficiency holds in the eu it considers the impact of potential forms of corporation tax harmonisation the results indicate that some commonly advocated reforms e g harmonising tax rates or tax bases would not significantly move the tax system towards production efficiency but that other reforms which affect the taxation of cross border flows would have more impact

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

strategic trade policy through the tax system if conventional instruments of strategic trade policy are unavailable the system of foreign profit taxation and transfer price guidelines may serve as surrogate policy instruments in this paper i consider a model where firms from two countries compete with each other on a market in a third country both firms have affiliates in the third country where part of the production takes place i analyse optimal policy choices of the firms residence countries aiming at strategically manipulating the competitiveness of their firms i show that first countries prefer the tax exemption system over the tax credit system if there is no intra firm trade second if the headquarters provide inputs for production in the affiliate countries prefer the tax exemption system if the transfer price for these inputs is close to the headquarters variable cost and if the residence country s tax rate is high however if transfer prices are high and the residence country s tax rate is low i show that the tax credit system is an optimal tax policy choice for both countries from a policy perspective the view that the tax exemption system is generally the best policy response if domestic firms competitiveness is a policy goal has to be qualified

pareto efficient international taxation this paper analyzes pareto efficient international tax regimes because every country faces its own national budget constraint the diamond mirrlees production efficiency theorem which underlies key tenets of policy advice in international taxation the desirability of destination basis for commodity taxation of the residence principle for capital income taxation and of free trade does not apply the paper establishes conditions relating to the availability of explicit or implicit devices for reallocating tax revenues across countries under which production efficiency is nevertheless desirable and characterizes the precise ways in which pareto efficient international taxation may require violation of established tenets

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

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

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

combined effects of capacity and time on fares insights from the yield management of a low cost airline abstract based on two strands of theoretical research this paper provides new evidence on how fares are jointly affected by in flight seat availability and purchasing date as capacity based theories predict it emerges that fares monotonically and substantially increase with flight occupancy after controlling for capacity utilization our analysis also supports time based theories indicating a u shaped temporal profile over a two month booking period as well as a sharp increase in fares in the two weeks prior to departure

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

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
