the uk demand for cigarettes 1954 1986 a double hurdle approach the double hurdle perspective suggests that it is crucial to distinguish between per capita and per smoker consumption when estimating the demand for cigarettes this paper presents a two equation model which identifies consumption and participation as two separate decisions the model is estimated with annual data on u k cigarette expenditure and participation rates highlighting the differing influence of prices income and health scares on the participation rate and on smokers demand for cigarettes

does monetary unification lead to excessive debt accumulation abstract if discretionary monetary policy gives rise to an inflation bias monetary unification boosts the accumulation of public debt the additional debt accumulation harms welfare if governments are sufficiently myopic in the presence of myopic governments debt ceilings play a useful role in avoiding excessive debt accumulation in a monetary union and allowing a conservative independent central bank to focus on price stability with supply shocks monetary unification results in excessive variability of public debt a debt target that constrains stabilization policy helps to prevent this

tobacco consumption and policy in the united kingdom in recent years several structural changes and sequences of shocks have occurred in the market for tobacco in the uk including an explosive growth in smuggling this study examines whether it is still possible to estimate a reliable plausible tobacco demand equation from time series data for the uk whilst allowing for all of the various shocks and structural changes a second objective of this study is to use the estimated demand function to evaluate tobacco policy in the uk including the scope for using tax increases to achieve reduced consumption and increased revenues it is found that smuggling has diminished the revenue yield of higher rates of duty but total consumption of tobacco has been reduced in addition to the introduction of further measures to control smuggling policy may need to place more emphasis in the future on health campaigns and smoking restrictions

how should control theory be used to calculate a time consistent government policy we study different solutions to a simple one dimensional linear quadratic game with a large number of private agents and a government a time consistent solution is defined as a solution to the hamilton jacobi bellman equation i e as a policy for which the government has noprecommitment capability this solution is compared to a policy where the government has an instantaneous pre commitment i e an equilibrium in which the government has a period by period leadership in both cases we show how control theory should be applied to calculate the equilibrium and how to relate these equilibria to the differential game literature

is there a tragedy of a common central bank a dynamic analysis a great deal of uncertainty exists about the degree to which a european central bank ecb can be exploited as common property by undisciplined governments in a dynamic game between symmetric national governments and a single monetary authority open loop strategies in the national setting coincide with strategies in the international setting compared to the open loop outcome feed back strategies slow down debt stabilization moreover debt adjustment is quicker with a common ecb than with individual central banks while inflation as well as fiscal deficits are lower these results conflict sharply with the notion of the ecb as common property

fiscal policy coordination with demand spillovers and unionised labour markets we explore the incentives for governments to cooperate by expanding expenditure we have three countries two are in a monetary union the emu the labour markets of both the emu countries are unionised and there is involuntary unemployment in equilibrium we explore the intra and intercountry effects of changes in bargaining power we then examine optimal government expenditures in each emu country we find that there is a positive spillover and that expenditures are strategic complements the coordinated equilibrium involves higher expenditure than the uncoordinated equilibrium

rules and discretion with noncoordinated monetary and fiscal policies the time inconsistency of optimal monetary policy is due to the effects of tax distortions thus the issue of how to improve upon the time consistent suboptimal monetary policy is related to that of the coordination of monetary and fiscal policy we present a model with three players the central bark the fiscal authority and wage setters in which distortionary taxes are explicitly modelled we show that binding commitments to monetary rules are not necessarily welfare improving if monetary and fiscal policy are not coordinated we also examine the effects of different degrees of independence of the central bank

the economics of exchange rate regimes a review essay the exchange rate regime issue has taken centre stage in discussions of international economic policy much of the profession appears to have been converted to the hypothesis of the vanishing middle regime for countries well integrated into world capital markets there is little if any middle ground between floating exchange rates and monetary unification this paper considers the exchange rate regime issue in the context of recent books on the subject by w max corden and morris goldstein both authors prescribe managed floating exchange rates supplemented with inflation targeting for emerging market economies under managed floating and with a credible monetary policy the public finances in order and strengthened debt management and prudential regulation the exchange rate is free to act as a market gauge for assessing policies and as a mode of conflict resolution both authors also argue however that no exchange rate regime is a holy grail ultimately a credible exchange rate regime depends upon the trust evoked by governments there is no exchange rate regime whether of the managed floating or hard fix variety that can eradicate a history of failed stabilisation attempts

a neo schumpeterian model of health services innovation the paper presents and empirically applies a neo schumpeterian model of innovation capable of studying interactions between service providers patients and policy makers and how these complex interactions determine the timing direction and success of innovations in the public sector the model is tested using a case study that traces the introduction and development of ambulatory surgery in a spanish hospital the multi agent model applies the ideas of schumpeter to services encompassing schumpeter s five types of innovation and re introducing the policy maker as a key agent in the innovation process the model has a number of advantages over previous reduced form models first it can analyse the interactions between the economic social and political spheres that make up the complex selection environment of innovations second it captures the recursive impact of radical innovations on agents competences and preferences and their relative power this brings politics power and rhetorical persuasion to the fore third it provides an improved set of definitions for radical and incremental innovation these are not only important for understanding the sources and drivers of innovation but also for the accurate measurement of innovation

from technological catch up to innovation based economic growth south korea and taiwan compared abstract this paper sets out to analyse the divergent models pursued by south korea and taiwan in regard to technological catching up and their ongoing transition towards innovation based economies it is found that south korea s former high debt and chaebol dominated model inclined it to pursue a schumpeterian scale based technological development while taiwan s former pro stability small and medium sized enterprise sme based model tended to favour its emphasis on a neo marshallian network based technological development it will be argued that the state s approach to economic liberalisation and firms demand for capital for technological upgrading are the major factors that have underpinned the adjustment efforts of these two countries

advertising and food drink and tobacco consumption in the united kingdom a dynamic demand system this paper tests for the influence of advertising on the inter product distribution of consumer demand for non durable goods and services in the uk 1963 1996 the long run demand for seven categories of non durable products is modelled through an advertising augmented version of the almost ideal demand system aids which is incorporated into an error correction model to allow for short run dynamic adjustments to long run equilibrium positions model estimates confirm that the restrictions of price homogeneity and symmetry appear to be consistent with the data yield measures of the various types of demand elasticity that are in general plausible confirm the strong influence of prices on the allocation of consumer expenditure but find little evidence to support the hypothesis that advertising has the power to effect marked changes in the inter product pattern of consumer demand in the uk

central bank independence and public debt policy the various proposals for the institutional design of the european monetary union have drawn fresh attention to the link between monetary and public debt policies this paper explores the strategic interaction between fiscal authorities setting public debt and the central bank controlling monetary policy in the absence of political distortions an optimally designed conservative independent central bank is sufficient to establish the second best in the presence of political distortions or with coordination of monetary and fiscal policy however also a debt target is needed

a model of currency depreciation and the debt inflation spiral abstract this paper shows how a government that cannot make credible policy commitments might manage its exchange rate and fiscal stance in a world of rational expectations the dynamic game model developed here potentially can generate diverse patterns of macroeconomic behavior patterns that differ as a result of assumed differences in government objectives under some types of government the ongoing strategic interaction between the public and private sectors leads to a disinflationary outcome other governments may push the economy into a spiral of rising debt and inflation

innovation in services the purpose of this article is to lay the foundations of a theory that can be used to interpret innovation processes in the service sector the hypothesis underpinning this article is based on lancaster s definition of the product in both manufacturing and services as a set of service characteristics the article follows the example of those who have sought to apply lancaster s work to technological phenomena various modes of innovation in the service sectors are highlighted and illustrated

can reputation resolve the monetary policy credibility problem abstract this paper addresses three problems with reputational equilibria in the barro gordon monetary policy game the multiplicity of equilibria the coordination problem and a chisel prone credibility problem a chisel proof credibility condition ensures that in response to a small deviation from the low inflation rate by the central bank it never pays for the private sector to acquiesce if the private sector can coordinate then a low but nonzero inflation outcome can be supported as a subgameperfect and chisel proof credible noncooperative equilibrium for an atomistic private sector the result can still hold in a game between successive monetary administrations

seasonality in dynamic regression models this paper examines the implications of treating seasonality as an unobserved component which changes slowly over time this approach simplifies the specification of dynamic relationships by separating non seasonal from seasonal factors we illustrate this approach using the consumption model of davidson et al 1978 and estimate a stable error correction model between consumption income and prices over the period 1958 92 more generally we argue that autoregressive models are unlikely to successfully model slowly changing seasonality and may confound seasonal effects with the dynamic responses of prime interest our approach can be used in a wide range of cases and we show that there is little loss in efficiency even if seasonality is deterministic

is addiction rational theory and evidence this paper makes two contributions to the modeling of addiction first we provide new and convincing evidence that smokers are forward looking in their smoking decisions using state excise tax increases that have been legislatively enacted but are not yet effective and monthly data on consumption second we recognize the strong evidence that preferences with respect to smoking are time inconsistent with individuals both not recognizing the true dife culty of quitting and searching for self control devices to help them quit we develop a new model of addictive behavior that takes as its starting point the standard rational addiction model but incorporates time inconsistent preferences this model also exhibits forward looking behavior but it has strikingly different normative implications in this case optimal government policy should depend not only on the externalities that smokers impose on others but also on the internalities imposed by smokers on themselves we estimate that the optimal tax per pack of cigarettes should be at least one dollar higher under our formulation than in the rational addiction case

monetary fiscal policy interactions and commitment versus discretion in a monetary union abstract we consider monetary fiscal policy interactions in a monetary union if monetary and fiscal authorities have different ideal output and inflation targets the nash equilibrium output or inflation or both are beyond the ideal points of all authorities leadership of either authority is better fiscal discretion entirely negates the advantage of monetary commitment the optimal monetary rule is equivalent to discretionary leadership of monetary over fiscal policy agreement about ideal output and inflation creates a monetary fiscal symbiosis yielding the ideal point despite disagreement about the relative weights of the two objectives for any order of moves without fiscal co ordination and without monetary commitment

financial interdependence and the state international monetary relations at century s end as the twentieth century draws to a close one can find sharply contrasting views among leading scholars on almost every key issue in positive international political economy how strong are international as opposed to domestic influences on policy how important are issues of national security high politics versus economic considerations low politics what role do institutions international and domestic play in influencing and constraining the behavior of governments why is international cooperation rare but not unheard of the list goes on and on

information shocks and cigarette addiction views from dynamic panels with common structural changes in this article we attempt to evaluate the impact of various information shocks on cigarette consumption in contrast to the existing studies we do not impose any break points a priori we use recently developed techniques for sample splitting in the data on us cigarette demand and find that using a time index as a transition variable can cluster cigarette demand into four distinct regimes in the past four decades a myopic to rational switch in cigarette consumption behaviour was observed in response to various anti smoking information events in particular we find strong evidence in support of the rational addiction model in the 1980s and 1990s moreover in line with the theoretical prediction our estimate of the long run elasticity is twice as large as the short run elasticity our empirical framework should improve policy makers understanding of the dynamics of cigarette consumption in response to various anti smoking campaigns and stress the role of sound policy making in improving smoking con

economic and monetary union in europe the european council s maastricht agreement maps out a precise route to monetary union and the eventual introduction of a common currency my discussion begins with a look at the general arguments for and against monetary union i shall then discuss the proposed constitution of the european central bank and whether it is likely to be conducive to monetary stability together with some of the problems posed by the transition to the new regime finally i will turn to the issue of rules for the conduct of fiscal policy and the question of fiscal federalism

service innovation in developing economies evidence from latin america and the caribbean abstractthis paper proposes a framework for understanding key aspects of service innovation in developing economies based on four dimensions first the integration of services in national innovation systems second competences and preferences third networking and cooperation and fourth outcomes in terms of socio economic impacts this conceptual framework is matched with new evidence from case studies performed in six different latin america and the caribbean countries argentina chile brazil uruguay costa rica and jamaica and nine sectors tourism software ict outsourcing mining logistics retail creative services sport services and biotech services the results reveal the importance of specificities in service innovation and suggest policy and managerial implications

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

rational addiction to caffeine an analysis of coffee consumption it is common knowledge that coffee tea and other beverages that contain caffeine are habit forming a recent medical study confirms that caffeine is strongly addictive with subjects exhibiting syndromes of intoxication withdrawal and dependence strain et al 1994 p 1043 that study concludes that the effect is physiological not just psychological it is of interest to ask whether the addictive nature of the most widely used psychoactive substance in the world is apparent from data on consumption there are several economic models of addiction among them the rational addiction model of becker and murphy 1988 stands out because of its simplicity and consistency with economic theory in this model the utility a consumer derives from consumption depends not only on the quantity c that is consumed but also on the degree of addiction at addiction is a form of human capital taking the form of a possibly harmful rather than beneficial stock variable it is increased as a by product of consumption and it gradually depreciates as time passes thus current consumption affects future choices consuming the good now increases its desirability in the future the becker murphy model is rational and forward looking in that the consumer is aware of these future effects and weighs them in making the current consumption choice this is in strong contrast to models that are based on assumptions of myopia and nonrational behavior an implication of the model is that this forward looking behavior can be detected in the data theory predicts that consumption data

business cycle convergence in emu a first look at the second moment we analyse the dynamics of the standard deviation of demand and supply shocks as well as of the demand component of gdp across countries in the european monetary union emu this analysis allows us to evaluate the patterns of cyclical comovement in emu and compare them the cyclical performance of the new members of the eu and other oecd countries we make use of sigma convergence methods to identify synchronization patterns in business cycles the eurozone has converged to a stable lower level of dispersion across business cycles during the end of the 80s and the beginning of the 90s the new eu members have also experienced a strong pattern of convergence from 1998 to 2005 when a strong divergence trend appears an enlargement of the emu to 22 members would not significantly decrease its optimality as a currency area there is evidence for some europe specific characteristics as compared to global comovements in business cycles authors abstract

the macroeconomics of social pacts in this paper we analyze macroeconomic interactions between trade unions the central bank and the fiscal policymaker we explicitly model unions concern for public expenditure paving the way for an analysis of the potential gains from cooperation between the fiscal policymaker and the unions i e the so called corporatist or social pacts that have characterized economic policies in a number of european countries in the last few decades we also highlight the profoundly different incentives generated by institutional arrangements such as the maastricht criteria and the stability and growth pact the former has unambiguously induced more efficient outcomes the latter is likely to backfire

reputation and time consistency recent work has shown that reputational arguments based on trigger strategies can sometimes be used to deal with the problem of time inconsistency in government policy this idea was exploited by robert barro and david gordon 1983 in a model of inflation and by v v chari and patrick kehoe 1988 in a model of capital taxation here it is shown that reputational arguments of this sort are widely applicable 2 a general policy model is developed based on an economy that is stationary over time contains identical households and has no endogenous state variables it is shown in general that the infinite horizon version of this model has equilibria in trigger strategies that yield outcomes strictly better than those attainable as equilibria in the one period model

a theory of rational addiction we develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time strong addiction to a good requires a big effect of past consumption of the good on current consumption such powerful complementarities cause some steady states to be unstable they are an important part of our analysis because even small deviations from the consumption at an unstable steady state can lead to large cumulative rises over time in addictive consumption or to rapid falls in consumption to abstention our theory also implies that cold turkey is used to end strong addictions that addicts often go on binges that addicts respond more to permanent than to temporary changes in prices of addictive goods and that anxiety and tensions can precipitate an addiction

the welfare economics of cooperative and noncooperative fiscal policy abstract in the absence of ricardian equivalence lump sum transfers between households within a country can alter the pattern of national saving and consumption allowing the government to exploit the country s size in world trade and in international borrowing and lending redistribution across generations through unfunded social security retirement schemes or public sector deficit finance with lump sum taxes and transfers enables a national planner to affect both the static and intertemporal terms of trade when trade restrictions or discriminatory taxation of asset income are unavailable due to international agreements the case for cooperative fiscal policy formation by governments of interdependent economies is examined in an overlapping generations economy with internationally perfectly mobile capital and a single relative price the world interest rate the optimum unfunded social security scheme when no distortionary tax instruments are allowed is derived for a government with nationalistic social preferences this policy targets both intergenerational distribution objectives and interest rate objectives the absence of distortionary taxes implies that no overall loss in world surplus need result from the strategic use of lump sum transfers so that coordination of intergenerational transfers is unnecessary for pareto optimality when internationally enjoyed public goods are introduced allocational efficiency requires cooperative selection of national exhaustive public spending programs but it does not demand that the financing of public expenditures be coordinated

congressional influence on u s monetary policy abstract congressional influence is generally discounted or ignored in political models of federal reserve behavior here i show that changes in the leadership of the senate banking committee are significantly correlated with monetary base growth more liberal committee leaders are associated with significantly higher base growth other factors held constant the result is shown to hold across several econometric specifications and different definitions of the congressional preference variable

loss of monetary discretion in a simple dynamic policy game abstract we analyze a simple policy game featuring monetary credibility problems and argue that loss of monetary discretion is not advantageous two elements form the basis of our analysis firstly we endogenize the source of credibility problems and secondly we consider a dynamic framework where credibility problems are not time invariant by doing this we are able to demonstrate that credibility problems are temporary and in steady state the government has removed these through sound policies a binding policy rule will only serve as an obstacle towards this steady state

permanent budget deficits and inflation abstract the issue of whether permanent primary budget deficits have to be monetized is re examined in a simple monetary model hybrid of the sidrauski and overlapping generations frameworks in which intergenerational effects are generated by the arrival of new infinitely lived cohorts the presence of intergenerational effects enlarges for a given fiscal policy the set of admissible monetary policies and weakens the need to monetize the deficit comparisons between the growth and interest rates are in general insufficient to predict whether increased deficit must be monetized because of the existence of both bond and money seigniorage laffer curves

estimating price elasticities when there is smuggling the sensitivity of smoking to price in canada a central parameter for evaluating tax policies is the price elasticity of demand for cigarettes but in many countries this parameter is difficult to estimate reliably due to widespread smuggling which significantly biases estimates using legal sales data an excellent example is canada where widespread smuggling in the early 1990s in response to large tax increases biases upwards the response of legal cigarette sales to price we surmount this problem through two approaches excluding the provinces and years where smuggling was greatest and using household level expenditure data on smoking these two approaches yield a tightly estimated elasticity in the range of 0 45 to 0 47 we also show that the sensitivity of smoking to price is much larger among lower income canadians in the context of recent behavioral models of smoking whereby higher taxes reduce unwanted smoking among price sensitive populations this finding suggests that cigarette taxes may not be as regressive as previously suggested finally we show that price increases on cigarettes do not increase and may actually decrease consumption of alcohol as a result smuggling of cigarettes may have raised consumption of alcohol as well

the shocking nature of output fluctuations in some eu countries recent literature on optimum currency areas has emphasized the importance of analysing the nature of the shocks facing the economy when deciding among alternative exchange rate regimes in this paper we use a structural var to model the joint behaviour of real output nominal interest rates real interest rates and real money balances in response to four exogenous disturbances identifying restrictions are used so that these disturbances can be interpreted as supply money supply is and money demand shocks the analysis is performed on five major european countries the principal objective is to investigate both the relative importance of these shocks in explaining the variance of output at different time horizons and the dynamic response of these economies to each type of shock evidence presented in this paper indicates that the five economies under study have faced very different types of economic shocks over the recent past the implication is that these countries are unlikely to meet the criteria f

symbiosis of monetary and fiscal policies in a monetary union we consider the interaction between the monetary policy in a monetary union and the separate fiscal policies of the member countries we use a barro gordon type model extended to many countries and fiscal policies each country s fiscal policies inflict externalities on other countries and the common monetary policy has its time consistency problem but if the two types of policymakers agree about the ideal levels of output and inflation then this ideal is attained despite disagreements about the weights of the objectives despite ex post monetary accommodation to fiscal profligacy without fiscal coordination without monetary commitment and for any order of moves

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

fiscal flows in the united states and canada lessons for monetary union in europe regional flows of federal taxes and transfers within the united states and canada are used to analyze long term fiscal flows the redistributive element and short term responses to regional business cycles the stabilization element in the united states long run flows amount to 22 cents in the dollar while the stabilization effect is 31 cents in the dollar in canada the redistributive effect is larger 39 cents and the stabilization effect smaller 17 cents federal flows appears to depend on the institutional structure of the country concerned however in both countries the redistributive element is considerably larger than the amounts involved in the ec structural funds program as for stabilization national fiscal policies in the ec appear to have been as effective as federal governments in the united states and canada in cushioning shocks to incomes

fiscal leadership and central bank design this article investigates the impact on economic performance of the timing of moves in a policy game between the government and the central bank for a government that has both redistributional and stabilization objectives it is shown that both inflation and income inequality are reduced without sacrificing output growth if the government assumes a leadership role compared with a regime in which monetary and fiscal policy are determined simultaneously further it is shown that government leadership benefits both the fiscal and monetary authorities through the enhanced coordination that this arrangement implies jel classification e52 e61 f42

implicit bands in the yen dollar exchange rate this article attempts to identify implicit exchange rate regimes for the yen dollar exchange rate to that end we apply a sequential procedure that considers both the dynamics of exchange rates and central bank interventions to data covering the period from 1971 to 2003 our results suggest that implicit bands existed in two subperiods april december 1980 and march october 1987 the latter coinciding with the louvre accord furthermore the study of the credibility of such implicit bands indicates the high degree of confidence attributed by economic agents to the evolution of the yen dollar exchange rate within the detected implicit band rate thus lending further support to the relevance of such implicit bands

comparisons of business cycles in the ec idiosyncracies and regularities annual data since 1960 and the real business cycle model as a guidance the evidence suggests that there are remarkable similarities between the business cycle pattern of these countries despite significant differences in the patterns of fiscal and monetary policies and the terms of trade we take this evidence to suggest that the type of shocks and the propagation mechanism is fairly similar across the ec countries hence the process of european integration under a set of uniform institutions and policies should not be a problem as far as the business cycle is concerned

strategic interactions of fiscal policies in europe a global var perspective abstract the paper analyses the strategic interactions of fiscal policies in the european union context by modelling the interdependencies arising between public and private sectors saving investment balances in a global vector autoregressive framework we use two empirical specifications to reflect some important differences in the sequencing of the policy decision making process in this setting we draw policy implications with respect to fiscal policy coordination and fiscal policy discretion we highlight the importance of several factors such as global capital flows uncertainty with respect to policy actions and nature of the shocks as key elements defining the dimension of the prevailing policy tradeoffs

time consistency of fiscal and monetary policy the problem of time inconsistency arises from two different sources first as shown by guillermo a calvo 1978 the re is an incentive for each government to engage in an initial unanti cipated inflation second as discussed by robert e lucas and nancy l stokey 1983 there is an incentive for each government to deviat e from the path of taxes announced by the preceding government in th is paper it is shown that these two sources of time inconsistency ca n be removed by a particular method of debt management involving bot h nominal and indexed government bonds of various maturities copyright 1987 by the econometric society

clean indoor air laws addiction and cigarette smoking cigarette demand equations derived from the becker and murphy 1988 model of relational addiction are estimated which include alternative measures of state level clean indoor air laws the laws have been the most widely used tool in the recent years of the anti smoking campaign survey data taken from the second national health and nutrition examination survey augmented with county level cigarette prices and excise taxes and state level measures of restrictions on smoking are used to estimate the demand equations clean indoor air laws are found to have a significant negative impact in average cigartte consumption increased restrictiveness of these laws beyond some basic level however is not found to further reduce smoking the effects of these restriction are found to differ across sexes average consumption among men is significantly reduced by the passage of the laws whereas smoking among women is unaffected finally cigarette prices are found of have a significant negative impact on consumpti

cooperative monetary and fiscal policies in the euro area this article discusses the interaction of fiscal and monetary policy in the euro area though many observers suggest a fiscal union as the next step of euro area constitutional reform a federal fiscal union does not appear politically feasible in the short run we suggest moving forward with cooperative monetary and fiscal institutions and policies that allow for decentralized fiscal decisions while taking federal stabilization policies into account this approach will increase the probability of survival of the euro area compared with the current fiscal arrangements using a dynamic macro model counterfactual simulation paths of our cooperative solution are contrasted with time series data for the euro area

money debt and deficits in a dynamic game this paper analyzes a dynamic linear quadratic game between the fiscal and monetary authorities the equilibrium outcome of the game determines the time path of money creation fiscal deficits and public debt the game is solved for different equilibrium concepts the equilibria are then compared and interpreted with reference to alternative institutional arrangements the main results are i coordination increases the speed of adjustment towards the steady state and takes the steady state value of public debt closer to the desired target ii precommitments take the non cooperative equilibrium closer to the coordinated outcome iii increasing the weight that each policymaker assigns to his own private objectives slows down the adjustment process places more burden on the opponent but has ambiguous effects on the steady state value of public debt

a bargaining model of partisan appointments to the central bank abstract in this paper a bargaining model is developed to analyze the appointment of central bankers in a two party political system the major results of the paper are 1 the party in power will appoint partisans early on but later appointments will be increasingly moderate in their views concerning monetary policy 2 changing the timing of the appointment of the board chairman from the end of a president s term in office to the first period of the president s term will lead to more partisan monetary policy 3 in equilibrium nominations to the board are not rejected thus confirmation hearings appear to be nothing more than a rubber stamp process 4 lengthening the terms on the board relative to the electoral cycle will lead to more moderate appointments to the central bank and a reduction in partisan policymaking

taxation smuggling and demand for cigarettes in canada evidence from time series data abstract this study analyzes canadian cigarette consumption and taxation between 1980 and 1994 a period in which there have been large price rises and declines and a dramatic increase in the consumption of contraband tobacco products we examine elasticities of legal cigarette sales and total sales including contraband with respect to the price of legal cigarettes and various other factors the growth of the contraband market since 1987 appears to have created two classes of cigarette taxed and untaxed with responses to changes in the legal price that are respectively higher and lower than was previously the case the sensitivity of total cigarette sales to the taxation instrument is much lower than it would appear from sales of taxed cigarettes alone

the economic consequences of president mitterrand france under mitterrand jeffrey sachs and charles wyplosz while french economic performance has not conformed to the enthusiastic promises of early 1981 this paper argues that the widely held view that it has been an unmitigated failure is unwarranted first the general deterioration can largely be dated back to the early seventies second the early and unfortunate attempt at a demand led expansion was both moderate in size and quickly reversed finally the post 1983 anti inflationary policies have been successful so that overall the disappointing french performance has been on a par with and in some ways better than the rest of europe but the main theme of the paper is the emphasis on the supply side the analysis is organized around the nairu the threshold rate of unemployment below which inflation rises in an attempt to explain the factors which have led to a continuous rise of the nairu since 1973 the paper focuses on labour costs particularly on the wedge between the costs borne by employers and net take home pay to achieve and sustain a significantly lower level of unemployment labour taxes must be cut thus reducing the wedge and the nairu and there must be a corresponding demand stimulus so that actual unemployment can fall to this level

wage rigidity and unemployment in oecd countries real wage rigidity is often blamed for causing unemployment in the wake of adverse real shocks like changes in productivity or the terms of trade likewise nominal wage rigidity is blamed for causing unemployment in the wake of adverse nominal shocks like falls in nominal demand 1 however there has been relatively little systematic discussion of how these concepts should be defined some authors e g sachs 1979 have defined real wage rigidity as the opposite of nominal wage rigidity with the us nominally rigid and europe really rigid 2 the rigidity of european real wages has then been used to explain why europe has experienced a greater increase in unemployment since 1973 than the us but in this discussion real wage rigidity has not been measured in a way which would in fact predict how much unemployment would result from a given real shock the discussion has focused on the degree of nominal inertia in the system but the unemployment cost of real shocks does not depend primarily on the degree of nominal inertia but rather on the effect of unemployment in the phillips curve

why do people drink tests of the rational addiction model the rational addiction ra model applied to alcoho consumption is tested using 1983 us health interview survey data the ra model yields refutable hypotheses concerning effects of current past and future prices past and future consumption time preference and marginal utility of wealth on addictive good consumption the estimations provide relatively strong support for the ra model past and present consumption had strong positive relationship with current consumption coefficients on past present and future money prices and fines for first oflence drunk driving as a form of price for alcohol consumption were significant and of the predical sign

conservative central bankers in a two country world abstract in a closed economy framework rogoff has developed the argument that it can be beneficial for society to appoint a conservative central banker we extend this analysis to a two country world in order to take into account the game between the monetary authorities of the two countries we show that conservative central bankers may now deteriorate the situations of both countries and that the distinction between symmetric and asymmetric shocks becomes crucial while symmetric shocks weaken the case for conservative central bankers asymmetric shocks strengthen it the paper also considers the case where central bankers are nominated noncooperatively by the countries

fiscal policy coordination and emu a dynamic game approach abstract this paper examines the case for fiscal policy coordination in a european economic and monetary union emu a two bloc model with two market structures is examined emu producing a single homogeneous good in both blocs emu1 and a two good emu emu2 where each bloc produces a single home good the european central bank sets monetary policy so as to achieve credibly low inflation rates we find that for emu2 as relative prices can change countries have an incentive to improve their terms of trade leading to an inefficient noncooperative outcome which can be avoided by cooperation

monetary union without fiscal coordination may discipline policymakers abstract with benevolent policymakers and fiscal leadership monetary unification reduces inflation taxes and public spending these disciplining effects of a monetary union which become stronger if the number of participants in the union increases are likely to raise welfare two types of arrangements are considered for the union s common central bank ccb making the ccb more conservative and imposing an inflation target on the ccb in contrast to the results of svensson 1997 svensson l e o 1997 optimal inflation targets conservative central banks and linear inflation contracts american economic review 87 98 114 an optimally designed conservative ccb may outperform inflation targeting finally we find that fiscal coordination offsets the disciplining effects of monetary unification hence subsidiarity in fiscal policymaking may enhance welfare

the demand for cocaine by young adults a rational addiction approach abstract this paper applies the rational addiction model to the demand for cocaine by young adults in the monitoring the future panel the price of cocaine is added to this survey from the drug enforcement administration s system to retrieve information from drug evidence results suggest that annual participation and frequency of use given participation are negatively related to the price of cocaine in addition current participation frequency is positively related to past and future participation frequency the long run price elasticity of total consumption participation multiplied by frequency given participation of 1 35 is substantial
