examining structural breaks and growth rates in international health expenditures over the last decade there has been a growing interest in examining health expenditures in this paper we study the behaviour of health expenditures in the g3 countries usa the uk and japan and three european countries the uk switzerland and spain over the period 1960 2000 from a different perspective in that we examine 1 whether there is a common structural break in health expenditures across the g3 and european countries 2 whether structural breaks have slowed down health expenditure growth rates in these countries or vice versa our main findings are that 1 health expenditures share a common break in both bivariate and trivariate cases and structural breaks and break intervals suggest that either one or a combination of events second oil price shock the 1987 stock market crash and or recessions have contributed to the commonality of break in health expenditures in the g3 while the oil price shocks have been instrumental in the commonality of breaks for the european countries 2 except for the uk structural breaks have slowed down growth rates in health expenditures for the usa japan switzerland and spain

state dependent pricing and the dynamics of money and output standard macroeconomic models of price stickiness assume that each firm leaves its price unchanged for a fixed amount of time we present an alternative model in which the pricing decision depends on the state of the economy we find a method of aggregating individual price changes that allows a simple characterization of macroeconomic variables the model produces a positive money output correlation and an empirical phillips curve in addition the impact of monetary shocks depends crucially on the current level of output which points to a natural connection between state dependent microeconomics and state dependent macroeconomics i introduction there is a long tradition in macroeconomics of attributing the real effects of nominal demand shocks to nominal price stickiness in this view if there is no change in prices when nominal demand rises then quantities must bear the burden of adjustment hence nominal price rigidity provides the friction needed for nominal demand shocks to be transmitted to the real economy standard models of this transmission mechanism such as fischer 1977 and taylor 1980 are based on the assumption that each firm leaves its price unchanged for a fixed amount of time the main reason for considering such time dependent pricing rules is their analytic tractability constraining firms to adjust their prices at prespecified times both simplifies the derivation of equilibrium strategies and allows the use of powerful time series techniques to analyze aggregate dynamics the main disadvantage of the timedependent approach is that between price adjustments firms are not allowed to respond even to extreme changes of circumstance this makes it difficult to know whether the qualitative effects of money in these models are the result of nominal rigidities per se or of the exogenously imposed pattern of price changes an alternative approach to modeling price stickiness is to allow the price setting decision to depend on the actual state of the

temporary stabilization a stochastic analysis abstract this paper develops a stochastic model of exchange rate based inflation stabilization in which agents have expectations of devaluation driven by a mixed diffusion jump process in a richer stochastic environment where a brownian motion drives the rate of devaluation and a poisson process determines the probability of devaluation we examine consumption and wealth equilibrium dynamics when a stabilization plan is implemented and contingent claims markets are unavailable we also assess the effects of exogenous shocks on consumption and welfare finally we use the proposed model to carry out a simulation experiment of the equilibrium dynamics

exchange rate based stabilizations a literature review the exchange rate based stabilizations erbss that have been undertaken in chronic inflation countries have generated a controversial body of literature regarding the effects of disinflation programs especially those on real consumption and output this survey provides an extensive overview of the literature on erbs the paper covers various empirical studies that have attempted to document the macroeconomic regularities associated with erbs discussing both their strengths and their weaknesses it analyzes diverse theoretical models that have been put forward to replicate the business cycles associated with erbs and sheds light on which models perform better using real data the results suggest that durables incorporated weak credibility and sticky price model proves to be most compatible with the empirical regularities observed in the course of erbs

a simple multivariate test for asymmetry since many macroeconomic models are linear it is not desirable to use themwith an asymmetric dependent variable in this article we formulate aunivariate test for symmetry based on the third cen

exchange rate management intertemporal tradeoffs exchange rate management is possible only if the government pursues consistent monetary and fiscal policies the authors constructa model in which the real consequences of exchange rate management depend on the precise time pattern of these policies the authors study the constraints on feasible policies and the comparative dynamics of disinflation by means of exchange rate targeting theoretical results are consistent with exchange rate managed disinflation attempts in argentina chile and israel copyright 1987 by american economic association

present value tests of the current account with durables consumption abstract the present value tests of the intertemporal model of the current account usually assume that all goods are traded and that aggregate consumption decisions can be closely approximated by a random walk process this paper extends these models by explicitly introducing durables and nontraded goods into an intertemporal model of the current account and tests the model using canadian data since aggregate consumption expenditures on durables do not exhibit random walk behavior even when the aggregate consumer has a quadratic utility function the model that includes durables makes predictions that differ from those of the basic approach when nontraded goods are also incorporated into the model the most appropriate income variable becomes output net of nontraded production these implications are examined using present value tests the results suggest that in the annual data introduction of both durables and nontraded goods improves upon the model with traded nondurables only this seems to be due to the combination of durables and nontraded goods as durables alone do not sufficiently refine the basic model

health care expenditure and gdp are they broken stationary in this paper we analyse the stationarity of the real per capita health care expenditure hce and real per capita gdp for a sample of oecd countries allowing for the presence of multiple structural breaks one novelty of the paper is that it permits the presence of structural breaks that affect both the level and the slope of the time series after the cross section dependence is accounted for we have found that these variables can be characterised as stationary processes evolving around a broken trend

a nonlinear approach to testing the unit root null hypothesis an application to international health expenditures in this article we examine the unit root null hypothesis for per capita total health expenditures hes per capita private hes and per capita public hes for 29 organization for economic co operation and development oecd countries the novelty of our work is that we use a new nonlinear unit root test that allows for one structural break in the data series we find that for around 45 of the countries we are able to reject the unit root hypothesis for each of the three he series moreover using monte carlo simulations we show that our proposed unit root model has better size and power properties than the widely used augmented dickey fuller adf and lagrange multiplier lm type tests

health care expenditure and integration in the countries of the european union national health care differs between the member states of the european union in the quality and quantity demanded and supplied reflecting different economic structures and health care organization and delivery systems since health care expenditure depends primarily on the level of economic development and the structure of the population only convergence in economic performance and the standards of living can lead to convergence of health expenditure standards

temporary stabilization predetermined exchange rates the paper analyzes the impact of a stabilization policy based on a temporary reduction in the rate of devaluation against a background in which a constant rate of devaluation has no real effects it is shown that the temporary policy does and furthermore that the real effects tend to become bigger in absolute value as the horizon of the temporary policy is shortened the central discussion is carried out in terms of a one good cash in advance model with perfect capital mobility and ramsey type consumers results are extended to account for home goods and variable velocity the roles of capital mobility and banking liberalization are briefly discussed

the price consumption puzzle of currency pegs abstract a defining stylized fact associated with exchange rate based stabilization programs is that their initial phase is characterized by several years of continuous expansion in private consumption and a gradual appreciation of the real exchange rate this paper shows that a large class of standard optimizing models is unable to account for this empirical regularity in particular models in this class predict that a gradual appreciation of the real exchange rate must necessarily be accompanied by a declining path of consumption the paper suggests several possible solutions to this problem and develops one in detail namely the relaxation of the assumption of time separability in preferences specifically it shows that under habit formation currency pegs induce a positive comovement between consumption and the real exchange rate the paper also establishes that habit formation provides an explanation for why in failed currency pegs a contraction in aggregate demand sets in before the collapse of the program

political cycles and exchange rate based stabilization fixed exchange rates implemented to increase credibility and attract foreign investment or as an alternative approach to stabilization in high inflation economies have been shown to be successful in expanding economic activity and correcting inflation in the short term but often lead to undesirable outcomes in the medium to long term although there is a wealth of literature documenting the boom bust cycles associated with the adoption of a nominal anchor no adequate explanation has been proffered as to governments repeatedly choosing policies that are self defeating the authors address this question with a political economy explanation based on the notion of a self interested government for which short term stabilization is attractive in the face of incentives posed by the electoral cycle if the election coincides with the boom phase of an exchange rate based stabilization incumbent governments increase the likelihood of gaining reelection and the bust phase will develop if at all only after the contest the authors thus suggest a modified version of the traditional political business cycle from the standpoint of a self interested office seeking government exchange rate based stabilizations can make good political sense empirical results based on an analysis of eighteen latin american countries from 1970 to 1999 support the insights of the argument movements towards a more fixed exchange rate are greater than three times more likely in a preelection period than in other stages of the electoral cycle

rural urban effects of terminating farm subsidies a rural urban interregional computable general equilibrium cge model is constructed to simulate the effects of terminating farm subsidies on household incomes employment rates farm and non farm sectoral activity regional costs of living and other economic indicators the magnitudes of the effects depend on regional factor and goods market segmentation robust short run implications are that ceasing farm subsidies would cause rural nonfarm particularly household service sector employment to fall and lead to lower household income on the other hand rural manufacturing activity expands and the cost of living falls relative to urban urban employment household income and land rents rise although termination of farm subsidies causes a decline in rural real product the urban real product gain outweighs rural losses

the dynamic effects of tax policies in a small open economy we develop an intertemporal optimizing model of a small open economy with both durable and nondurable consumption to address the implications of alternative tax policies an increase in lump sum taxes reduces the steady state level of consumption and improves the stock of foreign bonds consistent with empirical evidence durable consumption exhibits initial excess volatility though an increase in the tax on durables increases the demand for nondurables and improves the bond holdings in the steady state an increase in the tax on nondurables has insignificant effects on the stock of foreign bonds and the consumption of durables using quarterly data from the uk and estimating generalized impulse response functions we find empirical support we also calibrate the welfare implications of different tax policies

resurrecting the weak credibility hypothesis in models of exchange rate based stabilization abstract we analyze how weak credibility affects the volatility of consumption spending in a model of exchange rate based stabilization that allows for both durable and nondurable goods the inclusion of durables greatly improves the explanatory power of the weak credibility hypothesis the hypothesis can account for the main qualitative properties of the boom bust cycle provided the elasticity of durables expenditure with respect to tobin s q is greater than the intertemporal elasticity of substitution moreover the quantitative effects are very large in numerical simulations based on conservative assumptions about the expenditure share of durables 20 and wealth effects none aggregate consumption increases 17 22 and the real exchange rate appreciates 24 26 when the crawl decreases from 100 to zero for 3 years in variants of the model that incorporate supply effects the consumption boom is equally strong but appreciation of the real exchange rate rises to 30 40

a further contribution towards explaining why disinflation through currency pegging may cause a boom abstract we revisit the question of why exchange rate based erb disinflation is often expansionary we use an analytical dge model in discrete time with staggered wages if the policy is unanticipated and if the currency is pegged at the level it would have reached under unchanged policies then a boom occurs for preannounced erb disinflation our model also predicts a boom the explanation for both is that when wages are staggered wage setters have to be forward looking anticipating lower future inflation they reduce wages before the change in the exchange rate causing a favourable supply side effect on output

welfare and food assistance at the state and sub state level a framework for evaluating economic and programmatic changes welfare and food stamp program changes may affect local economies and economic changes may affect local program participation in this paper we outline a model of these interactions first we highlight key changes in the programs and report recent program and labor market participation patterns in metro and non metro portions of the midwest and the state of iowa then we describe computable general equilibrium cge model equations that formalize the types of choices being made and discuss the regional economic impacts that can be simulated in the process we raise several related research questions

stabilization policies in developing countries what have we learned abstract the paper reviews the recent experience with stabilization programmes in latin america in the light of traditional and monetarist models of inflation and the exchange rate the traditional model links both inflation and payments problems to budget deficits the monetarist model too believes that inflation is caused by fiscal deficits but it takes a more optimistic view of stabilization full purchasing power parity and perfect capital mobility make stabilization just a question of the appropriate exchange rate policy and the proper rate of domestic credit creation the traditional view is substantially right as a long run model but it fails in the dynamics the monetarist model is as we know now fundamentally wrong as a short run description of the possibilities of inflation control there is need and room for a paradigm that places emphasis on the debt money mix in financing the budget on the stickiness of inflation rates and on the place of short run real exchange rate and real interest rate variations that these are key features of the transition phase is amply borne out by the devasting and unsuccessful experiences with monetarist stabilization in argentina chile and brazil

exchange rate based stabilizations under real frictions the role of endogenous labor supply abstract this paper studies exchange rate based stabilization programs in the context of a model of a small open economy where labor supply is endogenous agents derive utility from both consumption and leisure in environments where consumption is subject to a cash in advance constraint a cut in the rate of devaluation lowers the nominal interest rate and hence alters the optimal mix of consumption and leisure the paper shows that in the presence of adjustment costs of investment a perfectly credible cut in the devaluation rate causes simultaneously a consumption and output boom a cumulative current deficit a sustained real appreciation of the domestic currency and an increase in labor supply over time it is also shown that an imperfectly credible stabilization program in this environment would have effects similar to the perfectly credible program but generate richer dynamics such as an initial boom in output followed by a recession which begins prior to the end of the program the model has clear welfare implications in that permanent reductions in inflation are unambiguously welfare enhancing

modern hyper and high inflations since 1947 hyperinflations by cagan s definition in market economies have been rare much more common have been longer inflationary processes with inflation rates above 100 percent per annum based on a sample of 133 countries and using the 100 percent threshold as the basis for a definition of very high inflation episodes this paper examines the main characteristics of such inflations among other things we find that i close to 20 percent of countries have experienced inflation above 100 percent per annum ii higher inflation tends to be more unstable iii in high inflation countries the relationship between the fiscal balance and seigniorage is strong both in the short and long run iv inflation inertia decreases as average inflation rises v high inflation is associated with poor macroeconomic performance and vi stabilizations from high inflation that rely on the exchange rate as the nominal anchor are expansionary

disinflation programs under policy uncertainty abstract this paper uses a model with endogenous labor supply to study exchange rate based inflation stabilization programs under uncertainty regarding the duration of the program the paper finds that the output and consumption dynamics induced by these programs are extremely sensitive to whether the programs are perceived to have a chance of continuing permanently or whether they are expected to end in finite time it is shown that the business cycle dynamics for output that are typically associated with these programs arise only when the policy is expected to collapse in finite time furthermore for the purposes of rationalizing the stylized facts the uncertain duration channel appears to induce a fundamental tension between the consumption dynamics and the current account dynamics these results raise doubts regarding the explanatory power of the uncertain duration channel in particular and the credibility channel in general

nominal interest rates consumption booms and lack of credibility a quantitative examination abstract exchange rate based stabilization programs in chronic inflation countries have often been accompanied by an initial expansion of private consumption followed by a contraction this consumption cycle has been attributed to lack of credibility in the sense that the public views the reduction in the devaluation rate as temporary this paper assesses the quantitative relevance of the temporariness hypothesis by comparing the predictions of a simple model to the actual figures for seven major programs the paper concludes that nominal interest rates must fall substantially for the temporariness hypothesis to account for an important fraction of the observed consumption booms

inflation stabilisation and the consumption of durable goods exchange rate based stabilisations in chronic inflation countries have often been characterised by an initial consumption boom which is most evident in the behaviour of durable goods followed by a later contraction this paper provides an explanation for such a boom recession cycle based on the timing of purchases of durable goods the initial fall in inflation results in a wealth effect which induces many consumers to bring forward their purchases of durable goods thus generating an aggregate consumption boom since most consumers replenish their stock of durable goods at the beginning of the programme a later slowdown follows

durability in consumption and the dynamics of the current account abstract in a model with durable goods and ricardian production technology an increase in government expenditure increases the steady state level of employment and reduces consumption the country runs a current account surplus the two factor model with costly investment akin to turnovsky and sen oxford econom pap 43 1991 1 confirms all the basic results of the simple model except for the current account balance the increase in capital has a negative effect whereas a decrease in the stock of consumer durables has a positive effect on the purchase of foreign bonds thus creating an ambiguous effect on the current account balance moreover the current account will likely exhibit non monotonic adjustment

the timing of purchases and aggregate fluctuations we study the cyclical effects of the timing of durable goods purchases in a general equilibrium model in which both durable and non durable goods are consumed and the durable good is lumpy at the microeconomic level the timing of durable goods purchases supplies some insulation for nondurable consumption over the cycle at the macroeconomic level the timing decisions tend to amplify and propagate wealth and income shocks our model also allows for endogenous price determination when the price of the durable changes due to inflexibility of workers between sectors the effect of adverse shocks is even stronger and longer copyright 2005 wiley blackwell

the food stamp program welfare reform and the aggregate economy the passage of the personal responsibility and work opportunity and reconciliation act prwora of 1996 swept away nearly six decades of federal welfare policy the act eliminated the aid to families with dependent children afdc entitlement program replacing it with a fixed block grant giving states a fundamental role in assisting poor families and added significant new work requirements for recipients although often overlooked in the extensive media coverage the food stamp program was changed fundamentally by the prwora the size of the food stamp program is expected to decrease by about 22 billion from 1997 to 2002 this is over half the

are health expenditures and gdp characterized by asymmetric behaviour evidence from 11 oecd countries in this article we examine whether per capita health expenditures and per capita gdp for 11 oecd countries can be characterized by asymmetric behaviour we achieve this goal by using the nonparametric triples test suggested by randles et al 1980 we examine two forms of asymmetries namely deepness and steepness our main finding is that for 6 out of 11 countries namely for the usa the uk japan spain finland and iceland either per capita health expenditures or per capita gdp are characterized by asymmetric behaviour this finding to some extent casts doubt on those studies that model the relationship between health and gdp using unit root and cointegration tests that assume symmetric disturbances

exchange rate based stabilisation durables consumption and the stylised facts in this article we show that a model featuring durable consumer goods imperfect substitution between domestic and foreign assets and weak credibility can explain the qualitative and quantitative aspects of the stylised facts associated with exchange rate based stabilisation including the tremendous increase in real interest rates following a temporary reduction in the crawl total consumption spending rises 14 26 the real exchange rate appreciates 20 37 and the current account deficit swells to 10 15 of gross domestic product despite large capital inflows the real interest rate increases from 10 to 20 100
