strategic capacity rationing to induce early purchases dynamic pricing offers the potential to increase revenues at the same time it creates an incentive for customers to strategize over the timing of their purchases a firm should ideally account for this behavior when making its pricing and stocking decisions in particular we investigate whether it is optimal for a firm to create rationing risk by deliberately understocking products then the resulting threat of shortages creates an incentive for customers to purchase early at higher prices but when does such a strategy make sense if it is profitable to create shortages what is the optimal amount of rationing risk to create we develop a stylized model to study this problem in our model customers have heterogeneous valuations for the firm s product and face declining prices over two periods customers are assumed to have identical risk preferences and know the price path and fill rate in each period via its capacity choice the firm is able to control the fill rate and hence the rationing risk faced by customers customers behave strategically and weigh the payoff of immediate purchases against the expected payoff of delaying their purchases we analyze the capacity choice that maximizes the firm s profits first we consider a monopoly market and characterize conditions under which rationing is optimal we examine how the optimal amount of rationing is affected by the magnitude of price changes over time and the degree of risk aversion among customers we then analyze an oligopoly version of the model and show that competition reduces the firms ability to profit from rationing indeed there exists a critical number of firms beyond which a rationing equilibrium cannot be supported

retail pricing and clearance sales sellers of new products are faced with having to guess demand conditions to set price appropriately but sellers are able to adjustprice over time and to learn from past mistakes additionally it is not necessary that all goods be sold with certainty it is sometimes better to set a high price and to risk no sale this process is modeledto explain retail pricing behavior and the time distribution of transactions prices start high and fall as a function of time on theshelf the initial price and rate of decline can be predicted and depends on thinness of the market the proportion of customers who are window shoppers and other observable characteristics copyright 1986 by american economic association

market structure and the value of overselling under stochastic demands in the operations management literature traditional revenue management focused on pricing and capacity allocation strategies in a two period model with stochastic demand inspired by travel and lodging industries we examine a two period model in which each seller may also adopt the overselling strategy to customers whose valuations are differentiated by timing of arrivals widely seen as a popular hedge against consumers skipping reservations we extend the stylized approaches of biyalogorsky carmon fruchter and gerstner 1999 and lim 2009 to understand the value of overselling under various market structures we find that contrary to existing literature the impact of period two pricing competition from overselling spills over to period one such that overselling may not always be a weakly dominant strategy once unlimited early demand ceases to hold in a duopoly regime we provide some numerical studies on the existence of multiple equilibria at the capacity allocation level which actually lead to different selling strategies at the equilibrium despite identical market conditions and firm characteristics

replicating ricardian equivalence tests with simulated series this paper replicates standard consumption function tests of ricardian equivalence using series generated from a model which nests ricardian equivalence within a non ricardian alternative due to finite horizons and or distortionary taxation the author shows that the estimates of the effects of taxation on consumption are not robust and that standard tests may have weaknesses which can lead to conflicting results whether ricardian equivalence holds or not the simulations also show that no clear conclusions about ricardian equivalence can be drawn from observing a low correlation between the current account and government budget deficits copyright 1997 by american economic association

non stationarities in financial time series the long range dependence and the igarch effects we give the theoretical basis of a possible explanation for two stylized facts observed in long log return series the long range dependence lrd in volatility and the integrated garch igarch both these effects can be explained theoretically if one assumes that the data are nonstationary

a computational analysis of japan s generalized system of preferences abstract in this paper we employ a general equilibrium computational model of world trade to evaluate the generalized system of preferences gsp of japan we conclude that the japanese gsp is strongly trade creating because preferential treatment is offered primarily on products for which japan is a major world exporter however tariff concessions result in a deterioration in japan s terms of trade which lowers welfare in japan and improves the welfare of japan s major trading partners among the ldcs the gain from preferential treatment accrues primarily to the asian nics hong kong south korea singapore and taiwan

the impact of a broad based energy tax on the us economy abstract this paper investigates the impact of a broad based energy tax on the us economy particularly the agricultural sectors the analytical approach used consists of a general equilibrium model composed of 12 producing sectors 13 consuming sectors six household categories classified by income and a government the effects of a 10 cents btu 10 6 tax on energy on prices and quantities are examined the results are revealing

exogenous tax changes and interest rates testing for ricardian equivalence using an efficient markets model this article tests the ricardian theory i e barro 1974 using mishkin s 1981 1982 efficient markets model of interest rates employing romer and romer s 2010 measure exogenous tax changes i am able to test whether the u s bond market reacts in a keynesian or ricardian manner to exogenous tax policy changes this helps avoid the endogeneity problems associated with measuring the interest rate effects of deficits and provides a cleaner test of the pure ricardian thought experiment i find a significant negative relationship between tax changes and interest rates which is inconsistent with the ricardian model and support the keynesian crowding out framework

on the optimal pricing policy of a monopolist the paper presents a simple explanation of price dispersion by a monopolist assuming only that consumers arrive in a random order and are served on a first come first served basis a firm can sometimes increase its profits by charging two different prices for the same good and rationing sales at the lower price however it is never necessary to charge more than two prices and a single price is sufficient as long as either the marginal revenue curve is everywhere downward sloping or the marginal cost of production is constant

the inherent dangers of using computable general equilibrium models as a single integrated modelling framework for sustainability impact assessment a critical note on bohringer and loschel 2006 the search for methods of assessment that best evaluate and integrate the trade offs and interactions between the economic environmental and social components of development has been receiving a new impetus due to the requirement that sustainability concerns be incorporated into the policy formulation process a paper forthcoming in ecological economics bohringer c loschel a in press computable general equilibrium models for sustainability impact assessment status quo and prospects ecological economics claims that computable general equilibrium cge models may potentially represent the much needed back bone tool to carry out reliable integrated quantitative sustainability impact assessments sias while acknowledging the usefulness of cge models for some dimensions of sia this commentary questions the legitimacy of employing this particular economic modelling tool as a single integrating modelling framework for a comprehensive evaluation of the multi dimensional dynamic and complex interactions between policy and sustainability it discusses several inherent dangers associated with the advocated prospects for the cge modelling approach to contribute to comprehensive and reliable sustainability impact assessments the paper warns that this reductionist viewpoint may seriously infringe upon the basic values underpinning the sia process namely a transparent heterogeneous balanced inter disciplinary consultative and participatory take to policy evaluation and building of the evidence base

developing countries and the gains from regionalism links between trade and farm policy reforms in mexico we use a multi country computable general equilibrium cge model with agricultural policy details to simulate the effects of north american free trade agreement nafta we find that mexico gains from nafta only when it also removes domestic distortions in agriculture in that case agriculture can generate allocative efficiency gains large enough to offset the terms of trade losses that arise because mexico has higher initial tariffs than its nafta partners when an rta forces a developing country to reform its domestic distortions that are linked to trade restrictions it becomes a building block toward multilateralism

omnichannel management with consumer disappointment aversion abstract with the popularity of omnichannel retailing consumers are sophisticated enough to make strategic channel decisions considering the possible disappointment for an unexpected outcome induced by various uncertainties from online and offline channels value uncertainty online can trigger low value disappointment and availability uncertainty offline may cause stock out disappointment this study characterizes the effect of consumers anticipated disappointment aversion behavior on the optimal pricing decisions of retailers with or without inventory constraint in the omnichannel environment when a retailer operates in dual channel and faces offline inventory constraint the concern for consumers homogeneous disappointment aversion changes the threshold above which the retailer implement different channel pricing strategies then we show how the negative impact of disappointment on profit and market can be mitigated by physical showroom mechanism which is increasingly adopted by omnichannel management introduction of a cost effective physical showroom expands the market by relaxing the restriction of stock out disappointment and improves profit as long as consumers low value disappointment is high enough interestingly the low value disappointment benefits the omnichannel in expanding the market coverage by alleviating the constraint exerted by stock out disappointment further discussions regarding the disappointment behavior are derived from the extension of consumers heterogeneity in disappointment aversion

the making of a hot product a signaling explanation of marketers scarcity strategy every marketer s dream is to create a hot product that customers would absolutely want to have thus generating considerable profit to the marketer according to one school of thought marketers should make products hard to get in order to create really hot products in this paper using a game theoretic model we investigate if such scarcity strategies can indeed be optimal while a scarcity strategy may appear to be a viable approach for making a firm s product successful further analysis raises some puzzling issues in particular it is not clear why a firm would not increase its price to get demand and supply in sync and increase its profit in the process we therefore offer a signaling explanation for the optimality of such strategies and show that a high quality seller may optimally choose to make the product scarce in order to credibly signal the quality of its product to uninformed customers our analysis indicates that a high quality seller optimally employs scarcity as a signaling device in product markets that are characterized ceteris paribus by a small difference in marginal cost between high and low quality products a low reservation price for a low quality product a greater heterogeneity in reservation prices for a high quality product and a moderate number of informed consumers our results provide a rationale for the fact that scarcity strategies are usually observed for discretionary or specialty products but not for commodity products staple products or new to the world products

stepping stones for biological invasion a bioeconomic model of transferable risk we investigate three sources of bias in valuation methods for ecosystem risk failure to consider substitution possibilities between goods failure to consider nonseparability of ecosystem services with market goods and failure to consider substitution possibilities between ecosystems the first two biases are known in the literature and we offer insight on the size of the bias for a specific example our work on spatially transferable risk is novel we develop the concept and show how it may undermine typical invasion prevention strategies we find three key results first partial equilibrium estimates of welfare loss are significantly overestimated relative to general equilibrium estimates if ecosystem services and market goods are substitutes the partial equilibrium bias is greater than if they are compliments second well intended policies do not necessarily reduce overall risk risk reduction actions can transfer risk to another time or location or both which may increase total risk third policies of quotas and inspections have to be extreme to improve welfare with inspections having advantages over quotas

the effect of oil price increases on four oil poor developing countries a comparative analysis abstract computable general equilibrium models are used to compare for four oil poor developing countries ivory coast kenya south korea turkey the short and medium run adjustment pressures arising from the second oil price shock the results emphasize the extent of expenditure switching and expenditure and wage reduction needed to accomodate the shock in each country cross country variations in the extent of required adjustment are traced to key structural differences between the four economies

is ricardian equivalence a good approximation ricardian equivalence may be a good approximation even if all households have finite horizons many households have short horizons and an appreciable fraction of wage income is received by liquidity constrained households the approximation is likely to be better the more imperfect annuity markets are

ricardian equivalence rational expectations and the permanent income hypothesis the ricardian equivalence proposition and the permanent income hypothesis are tested in an intertemporal consumption model with rational expectations the representative consumer incorporates the government budget constraint an alternative hypothesis of incomplete tax discounting is nested within this model a deterministic time trend is rejected for the variables of the model variables exhibit instead a stochastic trend the permanent income model is not rejected by annual u s data i e no excess sensitivity is found the evidence with respect to ricardian equivalence is mixed the empirical study employs theorems from the cointegration literature and specifically addresses issues of nonstationary regressors copyright 1990 by ohio state university press

on the possibility of an inverse relationship between tax rates and government revenues abstract when arthur laffer and other supply side advocates plot total tax revenue as a function of a particular tax rate they draw an upward sloping segment called the normal range followed by a downward sloping segment called the prohibitive range a brief literature review indicates that tax rates on the prohibitive range in theoretical and empirical models have been the result of particularly high tax rates high elasticity parameters or both the labor tax rate which maximizes total revenue for example will depend on the assumed labor supply elasticity this paper introduces a new curve which summarizes the tax rate and elasticity combinations that result in maximum revenues separating the normal area from the prohibitive area a general purpose empirical u s general equilibrium model is used to plot the laffer curve for several elasticities and to plot the newly introduced curve using the labor tax example results indicate that the u s could conceivably be operating in the prohibitive area but that the tax wedge or labor supply elasticity would have to be much higher than most estimates would suggest

optimal decisions for sellers considering valuation bias and strategic consumer reactions abstract in the online market for new and innovative products valuation bias commonly occurs between the initial valuation before purchase and the true valuation after purchase as a result of the consumer s lack of knowledge regarding the product valuation bias works in a complex manner on the one hand positive valuation bias increases the seller s demand while on the other hand it can also cause consumers to return their purchases which results in losses for the seller this paper first investigates the effect of the bias on the seller s optimal pricing the optimal price is determined always to increase strictly in the valuation bias if and only if the valuation bias does not exceed the consumer s return cost this result remains true regardless of whether the seller decides on the stocking quantity in addition to the valuation bias we consider strategic consumer reactions to the bias in two selling periods namely the advance period and the spot period our analysis finds that the seller s selling strategies e g pre announcing pricing trends are significantly affected by the relationship between valuation bias and the strategic consumer s estimation of the bias in addition though the optimal selling period is either the advance selling term or the spot selling term the seller does not need to provide for both periods sequentially we also determine that the unannounced pricing trend strategy and the announced non increasing pricing trend strategy are equivalent when the seller faces strategic consumers

using yield management to shift demand when the peak time is unknown traditional peak load and stochastic peak load models assume firms have prior information about when peak demand occurs however price dispersion such as is typically used by firms practicing yield management can achieve some of the same efficient demand shifting even when the peak time is unknown equilibrium price dispersion arises because of stochastic demand and price rigidities but a previously unexplored benefit of price dispersion is its ability to reduce equilibrium capacity costs through demand shifting the model also suggests how yield management now more commonly called revenue management might actually benefit business travellers contrary to the popular prejudice

reforming indirect taxes in canada some general equilibrium estimates the current indirect tax system in canada distorts economic activity in a variety of ways and has been the subject of considerable discussion as part of overall tax reform in this paper a general equilibrium model is used to analyze various changes in indirect taxes in canada focusing on possible changes to the federal and provincial sales taxes results suggest that replacing either the federal or provincial sales taxes with a broadly based sales tax yields a small but significant welfare gain the distributional effects from these changes are slightly regressive but appear to be quite small and easily offset by modest income tax credits targeted to low income households results also suggest that a broad based sales tax would be a significantly more efficient revenue source should additional sales tax revenues be required

an experimental examination of general equilibrium tax incidence abstract tax incidence is examined in an experimental general equilibrium production micro economy consistent with predictions the imposition of a tax on corporate capital resulted in a flow of capital out of the corporate sector decreased corporate usage of capital relative to labor and tax shifting through decreases in the relative prices of capital and non corporate output although capital owners were able to shift some of the tax burden the corporate tax resulted in a 35 drop in capital owner s share of payoffs implications for policy are discussed

general equilibrium analysis of black and white markets a computational approach abstract this paper explores the inter relationship between black and white markets and presents a formulation in which equilibrium conditions hold separately for each type of market for each product with linking conditions across market types using a traditional goods and factor general equilibrium model the simultaneous operation of price controls on white markets and surveillance with penalties for those caught trading on black markets is modelled a numerical example of such an economy is presented using data for india and equilibria under coexistence are reported

assessing ricardian equivalence this paper reviews the literature on ricardian equivalence this hypothesis may be interpreted as a generalisation to the short and the long run of the theories which put no weight on the real effects of public policies on aggregate demand we argue that ricardian equivalence relies on both permanent income hypothesis and the fulfilment of the intertemporal government budget constraint the theoretical literature emphasises several reasons for departures from this hypothesis however the empirical literature is inconclusive when ricardian equivalence is tested in a life cycle framework the hypothesis is usually rejected while when the empirical analysis is based on optimising models it is usually accepted

the impacts of tax reform on agricultural households estimates of tax reform s impacts usually concentrate on macroeconomic impacts but attention at the industry or sectoral level is often limited our study uses a computable general equilibrium cge model to estimate the disaggregated impacts of the tax cuts and jobs act tcja of 2018 which lowered personal and corporate tax rates focusing on agriculture we use survey data to calculate how the tcja would change the tax rates faced by farmers at the sector level we use internal revenue service data to calculate tax rates for all other producers we then simulate the economy wide and sectoral effects of tcja we find that the tcja would cause a reduction in agricultural output as resources would be reallocated to other sectors using our survey data we extend the cge results to measure the impacts to farm households from changes in on and off farm income we find that most farm households would have income gains from tax reform our tax reform scenario highlights the fact that investment weighs heavily on model results that is firms that are attractive to domestic and foreign investment have gains in demand for their products while other sectors such as primary agriculture experience decreases in production a sensitivity analysis that reduces the attractiveness of the united states in foreign investment shows smaller impacts of tcja especially for macroeconomic variables

the ricardian approach to budget deficits persistent budget deficits have increased economists interest in theories and evidence about fiscal policy this paper develops the ricardian approach and contrasts it with standard models the discussion considers from major theoretical objections to ricardian equivalence finite lifetimes imperfect capital markets uncertainty about future taxes and incomes and the distorting effects of taxation the paper then considers empirical evidence on interest rates consumption and saving and current account deficits the conclusion is that the ricardian approach is a useful first order approximation and that this approach will probably become the benchmark model for assessing fiscal policy this abstract was borrowed from another version of this item

reducing dependence on oil imports abstract the legacy of higher oil prices left by the 1970s has the oil importing economies reeling with another unexpected oil supply interruption threatening a knockout during the 1980s policies designed to reduce the level of oil imports have been the subject of intensive study but disagreements over their desirability has led to policymaking paralysis on the part of the major oil importing nations these disagreements have often resulted from differing views about how the world oil market works this paper considers a number of oil import reduction measures within a common framework that allows the effects of alternative assumptions about the world oil market to be investigated results from that framework suggest that there are many things that can be done to reduce dependence on oil imports with little cost and significant potential benefits under all but the most pessimistic world oil market assumptions

energy tariffs in a small open economy abstract tariffs on imported energy alter production and redistribute income the present paper examines a small open economy producing two traded goods with capital labor and imported energy a tariff reduces import and domestic factor income but payment to one domestic factor rises energy intensive output falls but the other output may rise in the general equilibrium political opinions on the tariff would differ revenue is concave in the tariff suggesting that the government might set the tariff to maximize revenue a simulation illustrates these general equilibrium properties across a range of tariffs

on reforming the welfare system abstract using a simulation model for a small open economy quebec 1986 various negative income tax nit and workfare schemes are compared from the point of view of efficiency and equity the main finding is that there exist workfare schemes that are superior both to the quebec regime of 1986 and to a nit characterized by a 100 percent implicit tax rate however these workfare schemes are dominated by some nit programs this suggests that it may be necessary to have work requirements that vary across socio demographic classes for a workfare plan to be superior to any nit combining workfare with an nit could also be the prescription

a computational general equilibrium model with endogenous unemployment an analysis of the 1980 fiscal reform in mexico abstract in this paper we develop a general equilibrium model of the mexican economy in which unemployment and government deficits play important roles the unemployment rate depends on a downwardly rigid real wage in the urban sector the government runs a deficit simply by selling bonds that consumers consider perfect substitutes for physical capital as savings instruments the model is used to analyze the impact of the 1980 fiscal reform the presence of the rigid real wage and alternative specifications of government policies regarding the size of the deficit are found to have significant effects on the comparative statics results whether or not the reform improves the welfare of rural households compared to urban households for example depends on whether government policy is to keep the deficit constant or keep expenditures constant in response to changes in tax revenues

carbon pricing and energy efficiency improvement why to miss the interaction for developing economies an illustrative cge based application to the pakistan case abstract carbon energy taxes and energy efficiency improvement are studied well in the recent years for their potential adverse impacts on economy especially for lost production and international competitiveness and rebound effects however little attention has been paid to investigate them jointly which can not only prevent fall of energy services cost and thereby rebound effect but reduce the associated macroeconomic costs this study thus employs a 20 sector cge model to explore separately the impacts of carbon tax and its coordinated implementation with energy efficiency improvement on the pakistan economy the country underwent enormous pressure of energy security issues as well as climate change fallouts in the last couple of years and can be regarded as a suitable candidate for energy environmental conservation policies to be considered at a broader context with more concrete efforts the simulation results show that the impact of carbon tax on gdp is negative but resulting reductions in pollutant emissions are relatively high moreover the gdp is expected to grow comparatively positive when analyzed with improvements in energy efficiency with even higher decline in energy consumption demand and so emissions this simultaneous economic and environmental improvement would thus have positive implications regarding sustainable development of the country

monetary policy and long term interest rates an efficient markets approach abstract this paper is an application of efficient markets theory to analyze empirically the relationship of money supply growth and long term interest rates this approach has the advantage over calier research on this subject in that it imposes a theoretical structure on this relationship that flows easier interpretation of the empirical results as well as more powerful statistical tests on the interest of ascertaining the robustness of the results many different empirical tests are carried out in this paper and they uniformly do not support the preposition that increases in the money supply are correlated with declines in long rates

the effects of energy taxes on the kenyan economy a cge analysis abstract the paper utilizes a computable general equilibrium model to evaluate the impact of the second oil price shock and consequent energy tax policies on the kenyan economy simulations show that dramatic change in energy prices and consequent changes in domestic energy consumption generate sequential feedbacks in the production process and affect economic structures terms of trade deteriorate the balance of payments deficit increases and national income falls energy import tariffs and a sales tax are effective policy instruments in controlling energy consumption and increasing government revenue both energy policies have net negative effects on other economic activities similar to those observed under the oil price shock as long as there are no other economically feasible sources of energy supplies there are economic losses associated with less petroleum product consumption in a net oil importing developing economy with oil intensive production technology

second best agricultural policy abstract since full economic liberalization is not generally feasible getting the prices of selected agricultural markets right involves optimal price distortions a methodology is developed for calculating the second best output price in a particular market by incorporating externalities government revenue constraints and distortions in other markets into the marginal social cost and benefit schedules for that market in the illustrative application to thailand tax friction consumption externalities and the optimal tariff argument are seen to support an export tax on rice even though import tariffs already discriminate against agricultural exports

a dominant strategy double auction a double auction mechanism that provides dominant strategies for both buyers and sellers is analyzed this mechanism satisfies the 1n convergence to efficiency of the buyer s bid double auction in addition the mechanism always produces full information first best prices the inefficiency arises because the least valuable profitable trade may be prohibited by the mechanism the mechanism has an oral implementation utilizing bid and asked prices

the efficiency gains from dynamic tax reform this paper presents a new simulation methodology for determining the pure efficiency gains from tax reform along the general equilibrium rational expectations growth path of life cycle economies the principal findings concern the effects of switching from a proportional income tax with rates similar to those in the u s to either a proportional tax on consumption or a proportional tax on labor income a switch to consumption taxation generates a sustainable welfare gain of almost 2 percent of lifetime resources in contrast a transition to wage taxation generates a loss of greater than percent of lifetime re sources a second general result is that even a mild degree of progressivity in the income tax system imposes a very large efficiency cost this abstract was borrowed from another version of this item

interest rates and expected future budget deficits in the united states several recent empirical studies have found no evidence of a positive association between interest rates and current and past budget deficits one possible explanation for this finding is that interest rates are related much more to the expectation of future budget deficits than to current and past budget deficits in this paper i investigate whether this explanation is valid finding no evidence that it is section ii briefly formulates and discusses the hypothesis under consideration stating some of its implications section iii presents the results of regressing the commercial paper rate moody s aaa bond rate and the ex post real commercial paper rate on current and past government spending budget deficits and real money supplies the regressions have been fitted to the entire sample of monthly data spanning the period between june 1908 and march 1984 and to 11

economic effects of vat reforms in germany in the tax policy debate differentiation of value added taxes is often justified by distributional concerns our quantitative analysis for germany indicates that such concerns are misplaced we find that the abolition of vat differentiation has only negligible redistributive effects instead reduced vat are found to act as industry specific subsidies whereas the overall welfare effects of pure vat reforms are very small a revenue neutral introduction of a harmonised vat combined with reductions in the marginal income tax rates or social security contributions turns out to produce substantial welfare gains for all households

property tax classification and welfare in urban areas a general equilibrium computational approach abstract this paper examines some of the structural and welfare effects of a change from a tax system in an urban area that classifies property by use for tax assessment to one that does not discriminate in its treatment of property a long run general equilibrium model of intraurban spatial location is developed due to analytical intractability the tax policy changes are simulated by use of a fixed point algorithm the model is stylized to the boston metropolitan area to the extent possible general equilibrium versions of compensating and equivalent variations in income are used as measures of welfare change the qualitative welfare results obtained from sensitivity analysis are fairly robust in a substantial majority of the cases considered there is a welfare gain in moving from the particular tax classification structure posited to a system in which all property is taxed at the same effective rate

the effect of money shocks on interest rates in the presence of conditional heteroskedasticity most current empirical work finds no evidence that money shocks lower interest rates we show that these nonresults are mainly due to a failure to model the conditional heteroskedasticity of interest rates autoregressive conditional heteroskedasticity arch models find a significant liquidity effect where ordinary least squares ols models do not the existence of a liquidity effect is found using different models and sample periods when arch models are used in estimation but never when ols is employed

government debt government spending and private sector behavior a current period tax reduction financed by issuing government debt shifts the timing of tax collection from the current period to the future if the future taxes implied by government debt are not fully perceived and discounted by the private sector there will be a net wealth effect that increases private sector consumption thus reducing capital accumulation and growth if on the other hand the implied future taxes are perceived and discounted by the private sector the current period tax reduction will be used to increase private saving to pay for the future taxes and government debt will be absorbed without any real effects on the economy the effects of government spending financed by current period taxation also depend upon private sector perceptions 2 if the benefits of government spending are ignored private sector consumption will decrease in accordance with the reduction in permanent disposable income to the extent that government spending is on consumption type goods that are perceived as substitutes for privately provided consumption goods there will be a relatively greater reduction in private sector consumption to the extent that government spending is on investment type goods yielding future goods and services that are perceived as substitutes for future privately provided consumption goods there will be a relatively smaller reduction in private sector consumption the standard approach to modeling private sector consumption saving behavior involves a rather asymmetric set of assumptions as to how the private sector perceives the various elements of government fiscal policy 3 current period taxes are assumed to be fully perceived but current period government spending is implicitly assumed to be completely ignored by the private sector in considering permanent personal disposable income the private sector is assumed to be forward looking in its assessment of income and taxation the stock of government debt is nevertheless included as part of the stock of private wealth the implicit assumption associate professor of economics graduate school of business university of chicago 1101 east 58th street chicago il 60637 i thank eugene fama levis kochin michael mussa paul evans and an anonymous referee for helpful comments i am particularly grateful to daniel benjamin for contributing many hours of discussion and laura lahaye who was a research assistant and valuable adviser on earlier drafts the theoretical debate on the burden of the debt has been long standing gerald o driscoll 1977 documents ricardo s nineteenth century position robert barro 1974 reopened the debate by introducing the fundamental issue of intergenerational transfers also discussed in merton miller and charles upton 1974 the empirical side of the debate was initiated by levis kochin s 1974 attempt to test for the effects of deficits on consumption and by martin feldstein s 1974 attempt to test for the effects of social security wealth on consumption other empirical contributions include jess yawitz and laurence meyer 1976 myself 1978 and j earnest tanner 1978 1979 with respect to the effects of government deficits and debt and barro 1978 michael darby 1979 and dean leimer and selig lesnoy 1982 with respect to social security wealth see also interesting recent papers by john seater 1982 who generates detailed tests of the effects of deficits and debt on consumption charles plosser 1982 who explores the effects of government spending and debt shocks on interest rates and feldstein 1982 who attempts tests similar to some in this paper see fn 29 2martin bailey s 1962 1971 development of the effects of government spending on private consumption and aggregate economic activity is the seminal contribution paul david and john scadding 1974 extend bailey s ideas and provide some supporting empirical evidence more recently willem buiter 1977 and myself 1978 developed models based on bailey s earlier work barro 1981 has an interesting paper on related issues see also david aschauer 1982 3the standard approach incorporates fiscal policy through the concept of personal disposable income and by including the stock of government debt as part of personal wealth see for example the empirical specification of albert ando and franco modigliani 1963 which has been the basis of most empirical consumption studies since and feldstein 1974 for one of the more influential papers based on the ando modigliani specification

optimal pricing with speculators and strategic consumers this paper studies a monopolist firm selling a fixed capacity the firm sets a price before demand uncertainty is resolved speculators may enter the market purely with the intention of resale which can be profitable if demand turns out to be high consumers may strategically choose when to purchase and they may also choose to purchase from the firm or from the speculators we characterize equilibrium prices and profits and analyze the long run capacity decisions of the firm there are three major findings first the presence of speculators increases the firm s expected profits even though the resale market competes with the firm second by facilitating resale the firm can mimic dynamic pricing outcomes and enjoy the associated benefits while charging a fixed price third speculative behavior may generate incentives for the seller to artificially restrict supply and thus may lead to lower capacity investments we also explore several model extensions that highlight the robustness of our results

peer induced fairness in games people exhibit peer induced fairness concerns when they look to their peers as a reference to evaluate their endowments we analyze two independent ulti matum games played sequentially by a leader and two followers with peer induced fairness the second follower is averse to receiving less than the first follower using laboratory experimental data we estimate that peer induced fairness between followers is two times stronger than distributional fairness between leader and follower allowing for heterogeneity we find that 50 per cent of subjects are fairness minded we discuss how peer induced fairness might limit price discrimination account for low variability in ceo compensa tion and explain pattern bargaining

what do regressions of interest rates on deficits imply economists analyses of the impact of federal deficits on interest rates are based primarily upon two alternative theories one of these says deficits force up interest rates while the other says they do not in their lucid exposition james barth george iden and frank russek 1 2 3 call the former the conventional and the latter the ricardian equivalence paradigm there are several studies attempting to assess empirically the impact of federal deficits on economic activity the congressional budget office 23 and b douglas bemheim 5 surveyed most of these studies and found that the evidence produced by these studies on the conventional and ricardian equivalence theories was inconclusive this finding agrees with that of barth iden and russek 1 2 3 the specific purpose is to extend barth iden and russek s computations and compare the out of sample forecasting performances of different estimates of the interest rate deficit connec

monetary policy and short term interest rates an efficient markets rational expectations approach this paper is an application of efficient markets rational expectations theory to analyze empirically the relationship of money supply growth and short term interest rates a hotly debated issue in the literature this approach has the advantage over earlier research on this subject in that it imposes a theoretical structure that allows easier interpretation of the empirical results as well as more powerful statistical tests the empirical results uniformly do not support the proposition that increases in money growth are correlated with declines in short rates the relationship between money supply growth and nominal interest rates is a hotly debated issue in the literature one view associated with keynesian structural macromodels has an increase in money growth leading at least in the short and medium runs to a decline in interest rates 2 an alternative view associated with milton friedman 6 7 indicates that interest rates might rise in response to higher money growth because there is a rise in inflationary expectations and hence a rise in interest rates through a fisher 5 effect

effects and mechanism of influence of china s resource tax reform a regional perspective abstract china s resource tax reform beginning with xinjiang as a pilot area in june 2010 marked a new stage in the progression of china s resource tax system based on the 2007 social accounting matrix sam for xinjiang constructed by ourselves this paper takes a regional perspective on china s resource tax reform to quantitatively calculate its degree of influence and qualitatively analyze its mechanism of influence by adopting an energy computable general equilibrium cge model and a sam price model the results show that the main significance of the reform lies in bolstering local government finances rather than energy conservation or carbon reduction this is because revenue will be transferred from resource enterprises and the central government to the local government while simultaneously the low tax rate narrow tax scope and unreasonable price mechanism will combine to prevent the reform from reaching its environmental goals promoting resource price mechanism reform and deepening resource tax reform will be two key elements of china s future energy strategies because resource enterprises will bear the increased burden caused by the reform the degree of sectoral price increases will be limited therefore the fear that resource tax reform will push up inflation is unnecessary and should not be a barrier to reform

evaluation of external market effects and government intervention in malaysia s agricultural sector a computable general equilibrium framework the purpose of this study is to evaluate the effects of changes in the external trade environment and domestic economic policies on the agricultural development of malaysia the scope of this research also includes providing further insights into the strengths and weaknesses of the computable general equilibrium cge methodology for agricultural policy analysis the first analysis focuses on the export agriculture sector which encompasses malaysia s two primary agricultural commodities rubber and palm oil heavily dependent on exports of rubber in the 1950s and 1960s malaysia has since built a more diversified economy with strong emphasis on manufacturing export agriculture however is still an important component of the national economy the second objective examines the influence of domestic policy on agricultural development the simulation results demonstrate the growing resiliency of the malaysian economy to external shocks also they point to the domestic economy s ability to buffer internal policy induced distortions

advance purchase discounts and monopoly allocation of capacity optimal pricing by a monopoly airline that faces capacity constraints during the peak demand period is studied the existence of capacity constraints means that in order to expand output the airline must divert demand from the peak period to the off peak period a particular advance purchase discount policy is shown to be the profit maximizing method of selling tickets if the advance purchase requirement were infeasible output and total surplus would both be lower jel l12 substantial discounts for air travel are generally available to travelers who are willing to purchase tickets a week or more in advance of the departure date this paper demonstrates why the imposition of an advance purchase requirement may be a profit maximizing strategy for a monopoly airline facing capacity constraints during times of peak demand 1 the practice of imposing an advance purchase requirement on discount tickets is also placed in a favorable light in terms of its impact on social

electronic tickets smart cards and online prepayments when and how to advance sell advance selling occurs when sellers allow buyers to purchase at a time preceding consumption shugan and xie 2000 electronic tickets smart cards online prepayments and other technological advances make advance selling possible for many if not all service providers these technologies lower the cost of making complex transactions at a greater distance from the seller s site they also give sellers more control over advance selling by decreasing arbitrage as technology enhances the capability to advance sell more academic attention is vital this paper strives to exploit these technologies by developing advance selling strategies until recently advance selling research focused on the airline industry and specific characteristics of that industry these characteristics included the price insensitivity of late arrivals e g business travelers compared with early arrivals e g leisure travelers demand uncertainty across flights on the same day and capacity constraints recent findings by shugan and xie 2000 show that advance selling is a far more general marketing tool than previously thought it does not require these industry specific characteristics it only requires the existence of buyer uncertainty about future valuations moreover sellers without the ability to price discriminate can use advance selling to improve profits to the level of first degree price discrimination this finding is important because buyers are nearly always uncertain about their future valuations for most services e g the utility of next year s vacation or a future college education in this paper we take the next step from shugan and xie 2000 we show that advance selling profits do not come from buyer surplus but from more buyers being able to purchase we determine when and how to advance sell in a variety of situations including situations with limited capacity second period arrivals refunds buyer risk aversion exogenous credibility continuous preference distributions and premium pricing we determine when advance selling improves profits and when it does how to set advance prices we ask and answer seven questions first when should sellers advance sell second how much can advance selling improve profits compared with only spot selling third what factors impact the profitability of advance selling and how fourth should advance prices be higher or lower or the same as spot prices fifth how do capacity constraints impact advance selling strategies sixth should sellers limit the number of advance sales finally what is the possible impact of buyer risk aversion first we provide precise conditions when sellers should advance sell for example without capacity constraints we show that sellers should advance sell when marginal costs are sufficiently low to make it profitable to sell to buyers with low valuations and sufficiently high to convince buyers that the spot price will be higher than the advance price second we find that advance selling can almost double the profits from optimal spot selling to early arrivals we also show that advance selling has no impact on consumer surplus in markets with homogenous consumers and no capacity constraints therefore advance selling can increase social welfare because seller profits increase third we find that two very important factors impacting the profitability of advance selling are seller credibility and marginal costs buyers only advance buy when they expect an advantage from advance buying over spot buying without capacity constraints sellers must credibly convince buyers that the advance price is at a discount to the spot price we show that this condition is met under different circumstances for example large marginal costs can create credibility because buyers believe that these costs will lead to high spot prices fourth we find although optimal advance prices can be at a discount to the spot price that sometimes a premium is optimal premiums are optimal when capacity is large but limited and marginal costs are not too large buyers advance purchase at a premium to spot prices when capacity is limited and spot prices are low note that this is not a risk premium and risk aversion is not required no prior research has suggested this strategy because that research relies on the assumption that early arrivals are more price sensitive than later ones without that assumption premium advance pricing is sometimes optimal fifth we find that binding capacity constraints can impact the profitability of advance selling in opposite ways on one hand capacity constraints create seller credibility buyers believe that spot prices will be high when they know spot capacity is limited and perhaps more limited by advance sales on the other hand when capacity is limited the need to increase sales from discounted advance prices diminishes sixth consistent with desiraju and shugan 1999 we find that limiting advance sales can be profitable but only under restrictive conditions these conditions are 1 selling to all early arrivals would leave insufficient capacity in the spot period to sell to all second period arrivals with high valuations 2 the optimal spot price is high and 3 marginal costs are sufficiently small to make advance selling profitable finally we find that buyer risk aversion can sometimes increase the profitability of advance selling our findings provide precise guidelines for a large number of service providers that will have the technical capability to advance sell for those service providers advance selling provides a creative pricing strategy that can potentially provide substantial improvements in profits

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

ricardian equivalence and the public and private saving nexus in india abstractthis study tests the ricardian equivalence theorem ret and examines the responsiveness of private saving to public saving in india most estimators do not provide support for the empirical validity of ret and long run cointegration between public and private saving the increases in household saving hhs seem to have been engendered by the provision of saving incentives institution of saving schemes self driven motivation to save and the precautionary accumulations induced by uncovered uncertainties in incomes rather than by ricardian behaviour of households the self imposed aversion to debt and debt bequest borrowing and liquidity constraints and the intertemporal smoothing of consumption have been the added catalysts that contributed to the increases in hhs the households with binding borrowing constraints inadequate or no insurance and uncovered uncertainties in incomes seem to have been saving more to pay for higher inflation tax the fiscal consolidation and generation of public s

are consumers ricardian evidence for the united states this paper derives three empirical implications of a well specified model of consumer behavior a model that nests both ricardian equivalence and an alternative non ricardian theory ricardian equivalence is then tested against this alternative the tests reveal that ricardian equivalence cannot be rejected

the effect of gasoline consumption tax on consumption and carbon emissions during a period of low oil prices abstract since june 2014 international crude oil prices have fallen sharply because of the new refined oil pricing mechanism china s domestic refined oil prices fell with the international oil prices during the period from november 28 2014 to january 12 2015 the china s domestic refined oil consumption tax had been increased for three times then the lowest price of refined oil was set to protect refined oil prices from further declining through financial means used to control the prices of refined oil can the goals of oil consumption reduction and harmful emissions mitigation be realised is it reasonable to use such a way adjusting refined oil consumption tax in this paper we construct an econometric model investigate the elasticity of china s gasoline demand and then make a further research on the effect of carbon dioxide co2 emission reduction we also study the rationality of the way adjusting the consumption tax we propose some policy suggestions based on the research in the context of the frequent fluctuations in international oil prices and the rising dependence on international crude oil in china according to our study compared with the developed countries e g the united states china s gasoline demand elasticity is not high however a certain extent tax adjustment can still guide consumers towards saving energy so as to achieve the purpose of controlling gasoline consumption and reducing co2 emissions the frequent tax adjustment reveals the irrationality of the refined oil pricing mechanism and the taxes policy china has entered the 13th five development term more reform measures should be proposed to build the crude oil market and improve the taxes policy

the parallel market of illegal aliens a computational approach abstract this paper develops the notion of illegal aliens as a parallel market in coexistence with the regular market of legal labor in the presence of both price controls on legal labor by minimum wage legislation and quantity controls on illegal aliens by immigration laws illegal aliens involve not only rural urban migration but also tax evasion and deportation costs we develop an analytical equilibrium structure which links markets for legal labor and illegal aliens illustrate how much an equilibrium can be computed and explore some implications of the linkage using united states data

exogenous shocks contagion and bank soundness a macroeconomic framework abstract in a model where all banks are initially solvent an exogenous shock affects confidence causing a flight from deposits into domestic and foreign currency real interest rates increase unexpectedly affecting firms and raising the share of the banks nonperforming assets this contagion causes a bank run simulations show that compensatory monetary policy mitigates the bank run but causes macroeconomic imbalances combining compensatory monetary policy with tight fiscal policies slows the bank run and mitigates insolvency a devaluation combined with compensatory monetary policy reduces insolvencies and increases the growth of real income but at the cost of increased inflation

advance selling when consumers regret we characterize the effect of anticipated regret on consumer decisions and on firm profits and policies in an advance selling context where buyers have uncertain valuations advance purchases trigger action regret if valuations turn out to be lower than the price paid whereas delaying purchase may cause inaction regret from missing a discount or facing a stockout consumers whom we describe as emotionally rational act strategically in response to the firm s policies and in anticipation of regret in this context regret explains two types of behavioral patterns inertia delayed purchase and frenzies buying early at negative surplus we show how firms should optimally respond to consumer regret and also characterize a normative regret threshold above which they should not advance sell action regret reduces profits as well as the value of advance selling and booking limit policies for price setting firms inaction regret has the opposite effects these effects are diminished by capacity constraints and are reversed for firms facing price pressure in the advance period owing e g to competition or market heterogeneity regret heterogeneity explains premium advance selling for the capacity constrained firm which may benefit from larger shares of regretful buyers finally we show how the negative effects of regret on profits can be mitigated by regret priming marketing campaigns and by offering refunds or options or allowing resales our results highlight the importance of assessing the relative strength of regret within and across market segments and of accounting for these factors in pricing and marketing policies this paper was accepted by christian terwiesch operations management

external sector closing rules in applied general equilibrium models abstract this paper examines formulations of external sector behavior adopted in some of the recent applied general equilibrium models in many cases these models are constructed for single economies and the model builder attempts to use a convenient external sector specification to close the model issues and difficulties with export demand and import supply functions for foreigners which satisfy trade balance and the modeling of small economy price taking behavior are explored

bank failures and fiscal austerity policy prescriptions for a developing country abstract this work employs a dynamic general equilibrium model to evaluate the causes and implications of bank insolvencies we apply the model to stylized data from bangladesh a country whose banking system is currently suffering from large stocks of non performing assets the model is used to derive positive conclusions about alternative policy instruments designed to alleviate the impact of these insolvencies a benchmark case is simulated using historical exogenous parameters we then generate a bank failure by assuming that firms cannot service their debt if their interest obligations rise above their anticipated return on capital the public withdraws deposits from the banking system in reaction to worries about defaulting bank assets if banks optimize by restricting credit to risky borrowers these failures can be partially avoided such bank behavior is often prohibited in developing countries so we investigate an active monetary policy that compensates banks for withdrawn deposits the resulting outcome indicates that such a policy can slow the pace of bank failures although at the cost of certain macro imbalances our final simulation imposes a reduction in public spending in order to tighten fiscal policy and thereby reduce budgetary pressure the resulting decline in interest rates eliminates all investor defaults and bank failures we conclude that the combination of compensating monetary policy and restrictive fiscal policy may offer the best way of responding to a bank crisis

bertrand competition with intermediation abstract we consider a duopolistic bertrand competition setting in which competing firms can turn into intermediaries the intermediation option allows firms to take advantage of the rival firm s low price we then give conditions for the existence of equilibrium

the interface between environmental and trade policies last march i gave the frank paish lecture to the society under the title economic life in a greenhouse in my lecture i tried both to survey professional opinion as to some of the possible climatic implications of the greenhouse effect and also to draw out the economic consequences which might follow towards the end of my talk i made reference to some preliminary joint work with randy wigle 2 a colleague at wilfrid laurier university in canada on the global consequences of carbon tax schemes designed to limit and or reduce the build up of co2 emissions a key element underlying the greenhouse effect the written version of the lecture consciously does not reproduce the survey material which made up the first part of the lecture instead it elaborates on the issues raised towards the end it incorporates the work by randy wigle and myself and offers some thoughts on what seems to be a growing issue for the iggos namely the consequences for the international trading system of interactions between trade issues and both future global and current national environmental policies what follows emphasises that if they occur in the next few decades global policy responses3 carbon taxes tradeable permit schemes to environmental concerns will almost certainly have large economic effects among these are likely to be significant effects on trade patterns and trade volumes large interregional effects will also accompany such policies depending upon how such policies are implemented also the i99os may see a growing use of trade measures to achieve objectives set for environmental policies environmental policies towards such countries as brazil the philippines and others where deforestation is a concern may increasingly take the form of threatened trade sanctions unless compliance with global environmental policy objectives occurs 4

purchasing pricing and quick response in the presence of strategic consumers we consider a retailer that sells a product with uncertain demand over a finite selling season the retailer sets an initial stocking quantity and at some predetermined point in the season optimally marks down remaining inventory we modify this classic setting by introducing three types of consumers myopic consumers who always purchase at the initial full price bargain hunting consumers who purchase only if the discounted price is sufficiently low and strategic consumers who strategically choose when to make their purchase a strategic consumer chooses between a purchase at the initial full price and a later purchase at an uncertain markdown price in equilibrium strategic consumers and the retailer make optimal decisions given their rational expectations regarding future prices availability of inventory and the behavior of other consumers we find that the retailer stocks less takes smaller price discounts and earns lower profit if strategic consumers are present than if there are no strategic consumers we find that a retailer should generally avoid committing to a price path over the season assuming such commitment is feasible committing to a markdown price or to not mark down at all is often too costly inventory may remain unsold even in the presence of strategic consumers the better approach is to be cautious with the initial quantity and then mark down optimally furthermore we discuss the value of quick response the ability to procure additional inventory after obtaining updated demand information albeit at a higher unit cost than the initial order we find that the value of quick response to a retailer is generally much greater in the presence of strategic consumers than without them on average 67 more valuable and as much as 558 more valuable in our sample in other words although it is well established in the literature that quick response provides value by allowing better matching of supply with demand it provides more value often substantially more value by allowing a retailer to control the negative consequences of strategic consumer behavior
