labor market institutions and inflation volatility in the euro area despite having had the same currency for many years emu countries still have quite different inflation dynamics in this paper we explore one possible reason country specific labor market institutions giving rise to different inflation volatilities when unemployment insurance schemes differ as they do in emu reservation wages react differently in each country to area wide shocks this implies that real marginal costs and inflation also react differently we report evidence for emu countries supporting the existence of a cross country link over the cycle between labor market structures on the one side and real wages and inflation on the other we then build a dsge model that replicates the data evidence the inflation volatility differentials produced by asymmetric labor markets generate welfare losses at the currency area level of approximately 0 3 of steady state consumption

the differential regional effects of monetary policy this paper examines whether monetary policy has similar effects across regions in the united states impulse response functions from an estimated structural vector autoregression reveal a core of regions new england mideast plains southeast and the far west that respond to monetary policy changes in ways that closely approximate the u s average response of the three noncore regions one great lakes is noticeably more sensitive to monetary policy changes and two southwest and rocky mountains are found to be much less sensitive a state level version of the model is estimated and used to provide evidence on the channels for monetary policy

inflation level and inflation volatility a seigniorage argument abstract we use a standard dynamic general equilibrium model with flexible prices money in the utility function exogenous fiscal policy and accommodating monetary policy to analytically demonstrate the positive relationship between the steady state level of inflation and business cycle inflation volatility this result holds in the presence of unique as well as multiple equilibria

some empirical evidence on the effects of shocks to monetary policy on exchange rates this paper investigates the effects of shocks to u s monetary policy on exchange rates we consider three measures of these shocks orthogonalized shocks to the federal funds rate orthogonalized shocks to the ratio of nonborrowed to total reserves and changes in the romer and romer index of monetary policy in sharp contrast to the literature we find substantial evidence of a link between monetary policy and exchange rates specifically according to our results a contractionary shock to u s monetary policy leads to i persistent significant appreciations in u s nominal and real exchange rates and ii significant persistent deviations from uncovered interest rate parity in favor of u s interest rates

the open economy consequences of u s monetary policy a failure to identify movements in the federal funds rate that are both unpredictable and independent of other determinants of open economy variables may lead to attenuation bias in the estimated effects of u s monetary policy on the exchange rate and foreign variables using a u s monetary policy measure which isolates unpredictable and independent federal funds rate changes we quantify the magnitude of the attenuation bias for the exchange rate and foreign variables the exchange rate appreciation following a monetary contraction is up to 4 times larger than a recursively identified var estimate there is stronger evidence of foreign interest rate pass through the expenditure reducing effects of a u s monetary policy contraction dominate any expenditure switching effects leading to a positive conditional correlation of international outputs and prices we compare our results with those obtained using identification based upon 1 non recursive var restrictions and 2 restrictions derived from high frequency asset price behavior

does inflation targeting improve fiscal discipline abstract we explore the performances of inflation targeting it adoption in terms of fiscal discipline fd while most existing studies focus exclusively on the role of fd as a precondition for it adoption using a sample of developing and developed countries we show that it adoption exerts a positive and significant effect on fd a result robust to a wide variety of alternative specifications in addition this effect is statistically significant only in developing countries a result that may fuel the current debate regarding the relevance of it adoption in general and particularly for developing countries

does joint modelling of the world economy pay off evaluating global forecasts from a bayesian gvar we analyze how modeling international dependencies improves forecasts for the global economy based on a bayesian gvar with ssvs prior and stochastic volatility to analyze the source of performance gains we decompose the predictive joint density into its marginals and a copula term capturing the dependence structure across countries the gvar outperforms forecasts based on country specific models this performance is solely driven by superior predictions for the dependence structure across countries whereas the gvar does not yield better predictive marginal densities the relative performance gains of the gvar model are particularly pronounced during volatile periods and for emerging economies

on the low frequency relationship between public deficits and inflation summary we estimate the low frequency relationship between fiscal deficits and inflation and pay special attention to its potential time variation by estimating a time varying vector autoregression model for us data from 1900 to 2011 we find the strongest relationship neither in times of crisis nor in times of high public deficits but from the mid 1960s up to 1980 employing a structural decomposition of the low frequency relationship and further narrative evidence we interpret our results such that the low frequency relationship between fiscal deficits and inflation is strongly related to the conduct of monetary policy and its interaction with fiscal policy after world war ii copyright 2015 john wiley sons ltd

fiscal deficits and inflation abstract macroeconomic theory postulates that persistent fiscal deficits are inflationary yet empirical research has had limited success in uncovering this relationship this paper reexamines the issue in light of broader data and a new modeling approach that incorporates two key features of the theory unlike previous studies we model inflation as non linearly related to fiscal deficits through the inflation tax base and estimate this relationship as intrinsically dynamic using panel techniques that explicitly distinguish between short and long run effects of fiscal deficits results spanning 107 countries over 1960 2001 show a strong positive association between deficits and inflation among high inflation and developing country groups but not among low inflation advanced economies

deficits money and inflation abstract this paper examines the interrelationships between monetary and fiscal policy specifically it seeks to determine whether government budget deficits influence monetary growth using a money supply model originally developed by barro we find that deficits have had a significant impact on the growth of the u s money supply throughout most of the period since 1961 such a relationship need not always hold it depends on whether government deficits place upward pressure on interest rates and whether the central bank monetizes the debt in an effort to stabilize interest rates

anchoring inflation expectations in the face of oil shocks in the proximity of zlb a tale of two targeters this paper applies a n ardl framework to two longstanding inflation targeting policy regimes in order to assess the relation between oil prices dynamics and inflation expectations and the further consequences created by a proximal zlb situation the application is based on data from january 1994 to june 2018 for new zealand and the uk we focus on oil price shocks as a variable of interest and this was found to have an asymmetric effect on inflation expectations one further key finding is that the real effective exchange rate has significant impacts on inflation expectations and this is indicative of an exchange rate pass through to inflation via an inflation expectations channel in general we find that inflation exchange rate money supply output growth unemployment and fiscal deficit surplus have significant implications for inflation expectations inflation expectations are also influenced by their past behaviour indicating adaptive inflation expectations this study contributes to the debate on the inflation targeting at zlb

seigniorage in a cross section of countries empirical investigation of the average level of seigniorage in a cross section of up to ninety countries for the period 1971 90 suggests that optimum tax theory explains up to 40 percent of the cross country variation in seigniorage since seigniorage is higher where its deadweight losses are probably lower and where deadweight losses from conventional taxation are probably higher but that average government spending is not a determinant of seigniorage practical concerns about financing transitory government spending explain some of the remaining variation in seigniorage and central bank independence and political instability are useful as well in contrast 90 percent of the cross country variation in conventional taxation appears to be determined by the level of government spending and deadweight losses and additional variables do not add to the results

external shocks u s monetary policy and macroeconomic fluctuations in emerging markets estimated structural vars show that external shocks are an important source of macroeconomic fluctuations in emerging markets furthermore u s monetary policy shocks affect interest rates and the exchange rate in a typical emerging market quickly and strongly the price level and real output in a typical emerging market respond to u s monetary policy shocks by more than the price level and real output in the u s itself these findings are consistent with the idea that when the u s sneezes emerging markets catch a cold at the same time u s monetary policy shocks are not important for emerging markets relative to other kinds of external shocks

how will emu affect inflation and unemployment in europe this paper explores how european monetary union will change the wage setting behavior of national labor unions we derive the impact of national inflation aversion and labor militancy on the performance of national labor markets under different monetary arrangements a common central bank raises inflation and unemployment if it acts as conservatively as national central banks however unemployment falls in countries that previously tied their monetary policy to the bundesbank we also examine the composition of emu and the influence of national labor market legislation jel classification e24 f02 f33

monetary policy cooperation may not be counterproductive this paper qualifies rogoff s famous 1985 result that international monetary policy cooperation is counterproductive in a model similar to his it is shown that if wage setters are non atomistic and inflation averse as policymakers are cooperation leads to higher employment and possibly lower inflation

monetary institutions monopolistic competition unionized labor markets and economic performance recent literature on the interactions between labor unions and monetary institutions features either a supply or a demand channel of monetary policy but not both this leads to two opposing views about the effects of central bank conservativeness we evaluate the relative merits of those conflicting views by developing a unified framework we find that i the effect of conservativeness on employment depends on unions relative aversion to unemployment versus inflation and ii for plausible values of this relative aversion and more than one union social welfare is maximized under a highly conservative central bank we also evaluate the effects of centralization of wage bargaining and product market competition on unemployment and inflation

to bi or not to bi differences between spillover estimates from bilateral and multilateral multi country models abstract asymptotic analysis and monte carlo simulations show that spillover estimates obtained from widely used bilateral such as two country var models are in general less accurate both in terms of bias and mean squared error than those obtained from multilateral such as global var models in particular the accuracy of spillover estimates obtained from bilateral models depends on two aspects of economies integration with the rest of the world first accuracy worsens as direct bilateral transmission channels become less important for example when the spillover sender accounts only for a small share of the spillover recipient s overall integration with the rest of the world second accuracy worsens as indirect higher order spillovers and spillbacks become more important for example when the spillover recipient is more integrated with the rest of the world overall empirical evidence on the global output spillovers from us monetary policy is consistent with these generic results spillover estimates obtained from two country var models are systematically smaller than those obtained from a global var model and the differences between spillover estimates obtained from two country var models and a global var model are more pronounced for economies for which the us accounts for a smaller share of their overall trade and financial integration with the rest of the world and for economies which are more integrated with the rest of the world overall

the world is not enough small open economies and regional dependence in this paper we explicitly introduce regional factors into a global dynamic factor model we combine new open economy factor models emphasizing global shocks with the recent findings of regional importance in the business cycle synchronization literature the analysis is applied to a large panel of domestic data for four small open economies we find that global and regional shocks explain roughly 30 and 20 percent respectively of the business cycle variation in all countries while global shocks have most impact on trade variables regional shocks explain a relatively large share of the variation in cost variables

budget deficits money growth and causality further oecd evidence abstract this paper investigates the causal linkage between budget deficits and money growth in seven major oecd countries using multivariate granger causality tests combined with akaike s aic criterion and zellner s iterative seemingly unrelated regressions the accommodation hypothesis that deficits granger cause positive long run changes in money growth is systematically rejected across all countries the reverse hypothesis that money growth granger causes long run changes in deficits is also rejected across countries these results suggest that monetary and fiscal policies are set independently in each of the oecd countries

multiple wage bargaining systems in the single european currency area little attention in the emu literature has been paid to the interaction between central bank monetary rules and systems of collective wage bargaining analytically and empirically coordinated wage bargaining systems respond with real wage restraint to non accommodating monetary policy since wage determination is dominated by collective bargaining in all the emu member states and wage coordination within the member states has grown since 1980 this is a topic of potential importance in particular the replacement of the bundesbank directly targeting german inflation by an ecb targeting european inflation has removed a major institutional support of wage restraint in germany the consequences of this for emu are worked out under two scenarios that inflation expectations will be generated by ecb monetary policy and that they will reflect german inflation outcomes possible institutional developments are discussed including government union bargains the bundesbank has also played a major role in maintaining fiscal rectitude by targeting excess fiscal deficits in germany again its replacement by the ecb targeting if at all european rather than german fiscal policy loosens fiscal constraints for underlying structural reasons therefore it is possible that germany and other emu countries will move to a period of fiscal activism with wage restraint and low inflation purchased through social contract negotiations

labour markets and monetary union a strategic analysis this paper shows that the effects of a monetary union depend on several labour market features in particular the switch from national monetary policies to a common monetary policy usually affects both inflation and unemployment even when all structural parameters of the economy and of unions and policymakers preferences remain the same the benchmark case of a monetary union between identical countries suggests that the switch to a monetary union is likely to make labour unions more aggressive increasing unemployment qualifications to this result are provided under alternative institutional scenarios like cross country asymmetries pre union erm membership and wage leadership

indeterminacy bubbles and the fiscal theory of price level determination abstract the recently developed fiscal theory of price level determination contends that there is an important class of policy rules in which there exists a unique rational expectations solution that shows the price level to be dependent upon fiscal policy and independent of monetary variables the present paper argues however that there is an alternative solution to these models that has entirely traditional or monetarist properties this latter solution is arguably more plausible since it is the solution that is typically regarded as the bubble free fundamentals solution the paper s analysis involves the specification of feasible instrument variables

examining asymmetries in the transmission of monetary policy in the euro area evidence from a mixed cross section global var model abstract i estimate the transmission of a common euro area monetary policy shock across individual euro area economies to do so i develop a global var model in which all euro area economies are included individually while at the same time their common monetary policy is modelled as a function of euro area aggregate output growth and inflation the results suggest that the transmission of monetary policy across euro area economies displays asymmetries and that in line with economic theory these are driven by differences in economies structural characteristics in particular euro area economies in which a higher share of aggregate output is accounted for by sectors servicing interest rate sensitive demand exhibit a stronger transmission of monetary policy to real activity similarly even though the evidence is less conclusive euro area economies which feature more real wage and or fewer unemployment rigidities also appear to display a stronger transmission of monetary policy to real activity

money as stock abstract the fiscal theory determines the price level from the value of nominal government debt as a claim to government primary surpluses just as private stock is valued as a claim to corporate profits valuation equations are not constraints so this theory does not mistreat the government s intertemporal budget constraint i anchor the analysis in a simple cash in advance model when money demand falls to zero i show that the price level can still be determined by the government debt valuation equation

macroeconomic effects of budget deficits further international evidence abstract this paper investigates the effects of budget deficits on money growth inflation investment and real output growth using annual data from a sample of 32 countries the findings can be summarized as follows i deficits are generally not monetized and therefore they do not produce inflation via monetary expansions ii deficits are not inflationary even through their alleged aggregate demand effects iii deficits are negatively correlated with the rate of growth of real output but this may just reflect their countercyclical nature and iv increased deficits do appear to retard investment usually after one or two years jel e63 h62

what caused the early millennium slowdown evidence based on vector autoregressions this paper uses a simple var for the usa and euro area to analyse the underlying shocks of the early millennium slowdown i e supply demand monetary policy and oil price shocks the results of two identification strategies are compared one is based on traditional zero restrictions and as an alternative an identification scheme based on more recent sign restrictions is proposed the main conclusion is that the recent slowdown is caused by a combination of several shocks negative aggregate supply and aggregate spending shocks the increase of oil prices in 1999 and restrictive monetary policy in 2000 these shocks are more pronounced in the usa than the euro area the results are somewhat different depending on the identification strategy it is illustrated that traditional zero restrictions can have an influence on the estimated impact of certain shocks copyright 2005 john wiley sons ltd

inflation and government deficits there is a pronounced positive correlation of inflation andgovernment deficits in the united states since world war ii the purpose of this paper is to test the three leading explanationsof this correlation these three explanations are a a deficitincreases prices through a wealth effect b a deficit results inthe federal reserve purchasing debt thus increasing the moneysupply and prices and c expected inflation increases the deficit which is the change in the nominal value of bonds no supportis found for either of the first two hypotheses the results indi cate that expected government deficits have no significance forfuture inflation since world war ii the united states has experienced large federal government deficits and a sustained peacetime inflation three differentconnections between the deficits and inflation are prominent in theliterature the most direct connection between government deficits and inflationis that by increasing the real value of outstanding bonds and perceived netwealth a deficit can raise total spending and the price level this connec tion is also the most long standing and is suggested by metzler 1951 andpatinkin 1965 for example monetarists generally and buchanan and wagner 1977 in particularhave emphasized a different link between deficits and inflation they sug gest that the federal reserve purchases government bonds when the trea sury sells bonds thus increasing high powered money the money supply and the price level the federal reserve might behave this way for exam ple because it is attempting to hold down interest rates on governmentsecurities when deficits occur recently barro 1978 1979 has put forward a hypothesis that deficitsare a result of inflation rather than inflation being a result of deficits thegovernment deficit is the change in the nominal value of outstanding gov ernment bonds if the anticipated inflation rate increases then the nomi nal value of bonds must increase i e the government will run a deficit tokeep the same anticipated real amount of bonds all three of these possible connections between government deficitsand inflation are consistent with the observed positive correlation of defi cits and inflation the implications however are strikingly different con

business cycle transmission from the us to germany a structural factor approach abstract this paper investigates the transmission of us macroeconomic shocks to germany using a large dimensional structural dynamic factor model this framework allows us to investigate many transmission channels simultaneously including new channels such as stock markets foreign direct investment bank lending and the confidence channel we find that us shocks affect the us and germany largely symmetrically trade seems to be the most relevant transmission channel monetary policy reactions to strong price movements seem to play a role as well no clear conclusion can be drawn yet on the role of financial markets and the confidence channel negative domestic influences apparently more than offset positive us influences in the german economy between 1995 and 2000 but the us recession in 2001 appeared to be the main culprit in the german slump

size openness and macroeconomic interdependence the curse of dimensionality a problem associated with analyzing the interaction of a relatively large number of endogenous macroeconomic variables is a prevailing issue in the open economy macro literature the most common practice to mitigate this problem is to apply the so called small open economy framework soef in this paper we aim to review under which conditions the soef is a justifiable approximation and how severe the consequences of violation of key conditions might be thereby we use a multicountry general equilibrium model as a laboratory first we derive the conditions that ensure the existence of the equilibrium and study the properties of the equilibrium using large n asymptotics second we show that the soef is a valid approximation only for economies i that have a diversified foreign trade structure and if ii there is no globally dominant economy in the system third we illustrate that macroeconomic interdependence is primarily related to the degree of trade diversification and not to the extent of trade openness furthermore we provide some evidence on the pattern of global macroeconomic interdependence by calculating probability impulse response functions in our calibrated multicountry model using data for 153 economies

china s emergence in the world economy and business cycles in latin america the international business cycle is very important for latin america s economic performance as the recent global crisis vividly illustrated this paper investigates how changes in trade linkages between china latin america and the rest of the world have altered the transmission mechanism of international business cycles to latin america

monetary union and pegging in the presence of labor unions as the european economic and monetary union grows power over monetary policy is shifting away from the original founders previously researchers have analyzed the impact of replacing an exchange rate peg with a monetary union in the presence of labor unions in these studies the authors have consistently concluded that unemployment in the country that originally controlled monetary policy will rise although they cite very different reasons in this paper we present a more general model that reproduces the previous results in special cases and clarifies the relations across the results in addition the more general model shows that the results are reversed in certain conditions

has the transmission mechanism of european monetary policy changed in the run up to emu abstract this paper studies empirically the transmission mechanism of european monetary policy by means of time varying heterogeneous coefficient models estimated in a numerical bayesian fashion based on pre european monetary union evidence from germany france italy and spain we find that i the long run cumulative impact on output of a common homoskedastic monetary policy shock has decreased in all countries after 1991 these declines are statistically significant and accompanied by some changes in the conduct of monetary policy over the same period at the same time we also find that ii cross country differences in the effects of this shock have not decreased over time

fiscal requirements for price stability maintaining price stability requires not only commitment to an appropriate monetary policy rule but an appropriate scal policy rule as well ricardian equivalence does not imply that scal policy is irrelevant except in the case of a certain class of policies ricardian policies the role of scal developments in inflation determination under a non ricardian regime is illustrated through an analysis of the bond price support regime of the 1940s a monetary scal regime with attractive properties would combine a taylor rule for monetary policy with nominal decit targeting as a scal policy commitment

central bank independence and macroeconomic performance some comparative evidence this note uses information on a sample of sixteen oecd countries to assess the relationship between central bank independence and macroeconomic performance as previous work suggests politically controlled central banks are more likely to pursue policies that lead to high and variable inflation however the authors find little evidence that political control of central bank policy has any impact on measures of the level or variability of growth unemployment or the ex ante real interest rate copyright 1993 by ohio state university press

identifying monetary policy in a small open economy under flexible exchange rates abstract previous empirical study on the effects of monetary policy shocks in small open economies has generated puzzling dynamic responses in various macroeconomic variables this paper argues that these puzzles derive from an identification of monetary policy that is inappropriate for such economies to remedy this it is proposed that a structural model be estimated to explicitly account for the features of the small open economy such a model is applied to canada with tightly estimated results overall the dynamic responses to the identified monetary policy shock are consistent with standard theory and highlight the exchange rate as a transmission mechanism

the impact of government deficits on money growth in developing countries abstract this paper investigates the relationship between government budget deficits and money growth in the developing countries for which reliabile data exist it is sometimes suggested that it is more likely that money growth follows debt growth in developing countries due to the embryonic state of capital markets and because the central bank generally comes under direct control of the minister of finance our results provide only mixed support for this contention however in the majority of countries in our sample there is no evidence that government deficits affect money growth for high inflation years there seems to be more support for a relationship between deficits and money growth

the transmission of international shocks a factor augmented var approach the empirical literature on the transmission of international shocks is based on small scale vars in this paper we use a large panel of data for 17 industrialized countries to investigate the international transmission mechanism and revisit the anomalies that arise in the empirical literature we propose a factor augmented var favar that extends the model in bernanke boivin and eliasz 2003 to the open economy the main results can be summarized as follows first the dynamic effects on the uk economy of an unanticipated fall of short term interest rates in the rest of the world are real house price inflation investment gdp and consumption growth peak after one year wages peak after two years cpi and gdp deflator inflation peak during the third year second a positive international supply shock makes the distribution of the components of the uk consumption deflator negatively skewed third in response to a domestic monetary shock we find no evidence of the exchange rate and liquidity puzzles and little evidence of the forward discount and price anomalies

relative price changes as aggregate supply shocks this paper proposes a theory of supply shocks or shifts in the short run phillips curve based on relative price changes and frictions in nominal price adjustment when price adjustment is costly firms adjust to large shocks but not to small shocks and so large shocks have disproportionate effects on the price level therefore aggregate inflation depends on the distribution of relative price changes inflation rises when the distribution is skewed to the right and falls when the distribution is skewed to the left we show that this theoretical result explains a large fraction of movements in postwar u s inflation moreover our model suggests measures of supply shocks that perform better than traditional measures such as the relative prices of food and energy

the regulation of labor author s botero juan djankov simeon la porta rafael lopez de silanes florencio shleifer andrei abstract we investigate the regulation of labor markets through employment collective relations and social security laws in 85 countries we find that the political power of the left is associated with more stringent labor regulations and more generous social security systems and that socialist french and scandinavian legal origin countries have sharply higher levels of labor regulation than do common law countries however the effects of legal origins are larger and explain more of the variation in regulations than those of politics heavier regulation of labor is associated with lower labor force participation and higher unemployment especially of the young these results are most naturally consistent with legal theories according to which countries have pervasive regulaory styles inherited from the transplantation of legal systems

are fiscal deficits inflationary abstract this paper applies the dynamic panel quantile regression dpqr model under the autoregressive distributional lag ardl specification and examines the deficit inflation relationship in 91 countries from 1960 to 2006 the dpqr model estimates the impact of deficits on inflation at various inflation levels and allows for a dynamic adjustment with the ardl specification the empirical results show that the fiscal deficit has a strong impact on inflation in high inflation episodes and has a weak impact in low inflation episodes the results imply that fiscal consolidation would be more effective in price stabilization the higher the inflation rate is and are consistent with the theoretical model of catao and terrones 2005

monetary policy and exchange rate overshooting dornbusch was right after all abstract dornbusch s exchange rate overshooting hypothesis is a central building block in international macroeconomics yet empirical studies of monetary policy have typically found exchange rate effects that are inconsistent with overshooting this puzzling result has been viewed by some researchers as a stylized fact to be reckoned with in policy modelling however many of these studies in particular those using vector autoregressive vars approaches have disregarded the strong contemporaneous interaction between monetary policy and exchange rate movements by placing zero restrictions on them in contrast we achieve identification by imposing a long run neutrality restriction on the real exchange rate thereby allowing for contemporaneous interaction between the interest rate and the exchange rate in a study of four open economies we find that the puzzles disappear in particular a contractionary monetary policy shock has a strong effect on the exchange rate which appreciates on impact the maximum effect occurs within 1 2 quarters and the exchange rate thereafter gradually depreciates to baseline consistent with the dornbusch overshooting hypothesis and with few exceptions consistent with uncovered interest parity uip

are money growth and inflation related to government deficits evidence from ten industrialized economies abstract we present empirical evidence on the relation between the government debt growth money growth and inflation for ten industrialized countries over the post world war ii period non parametric and parametric tests reveal little evidence that government debt growth is either related to money growth or permanently related to inflation over periods of a decade or less but the level of debt is significantly associated with subsequent inflation from 1974 to 1983 these results are consistent with the hypothesis that central banks in developed economies can conduct independent monetary policy over long periods notwithstanding government deficits

strategic monetary policy with non atomistic wage setters monetary policy analyses usually assume an atomistic private sector thereby ignoring potential interactions between policy and wage setting decisions yet non atomistic wage setters are a key feature of several industrialized economies we study the economic consequence of non atomistic agents and show that this qualifies previous results on the effects and desirability of a conservative central banker in particular the central bank aversion to inflation may have a permanent effect on structural employment while no such effect emerges with atomistic agents

a non walrasian labor market in a monetary model of the business cycle abstract this paper investigates to what extent a new keynesian monetary model with the addition of a microfounded non walrasian labor market solely based on union bargaining is able to replicate key aspects of the business cycle the presence of a representative union offers an explanation for two features of the cycle first it generates an endogenous mechanism which produces persistent responses to both supply and demand shocks second labor unionization reduces the elasticity of marginal costs to output this leads to lower inflation volatility model simulations show that the unionized framework can better reproduce european business cycle data than can a model with a competitive labor market

inflation openness and exchange rate regimes the quest for short term commitment abstract this paper further tests romer s romer d 1993 openness and inflation theory and evidence quarterly journal of economics 58 869 903 extension of kydland and prescott s kydland f prescott e 1977 rules rather than discretion the inconsistency of optimal plans journal of political economy 85 473 491 predictions for dynamic inconsistency problems in open economies in a panel data set of developed and developing countries from 1973 to 1998 i find that openness does not play a role in restricting inflation in the short run on the other hand a fixed exchange rate regime plays a significant role the results are robust to controlling for other variables that determine inflation performing sensitivity analysis and using a de facto exchange rate regime classification

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

cross country causes and consequences of the crisis an update abstract we update rose and spiegel forthcoming rose and spiegel 2010 and search for simple quantitative models of macroeconomic and financial indicators of the great recession of 2008 09 we use a cross country approach and examine a number of potential causes that have been found to be successful indicators of crisis intensity by other scholars we check a number of different indicators of crisis intensity and a variety of different country samples while countries with higher income and looser credit market regulation seemed to suffer worse crises we find few clear reliable indicators in the pre crisis data of the incidence of the great recession countries with current account surpluses seemed better insulated from slowdowns

long term debt and optimal policy in the fiscal theory of the price level the fiscal theory says that the price level is determined by the ratio of nominal debt to the present value of real primary surpluses i analyze long term debt and optimal policy in the fiscal theory i find that the maturity structure of the debt matters for example it determines whether news of future deficits implies current inflation or future inflation when long term debt is present the government can trade current inflation for future inflation by debt operations this tradeoff is not present if the government rolls over short term debt the maturity structure of outstanding debt acts as a budget constraint determining which periods price levels the government can affect by debt variation alone in addition debt policythe expected pattern of future state contingent debt sales repurchases and redemptionsmatters crucially for the effects of a debt operation i solve for optimal debt policies to minimize the variance of inflation i find cases in which long term debt helps to stabilize inflation i also find that the optimal policy produces time series that are similar to u s surplus and debt time series to understand the data i must assume that debt policy offsets the inflationary impact of cyclical surplus shocks rather than causing price level disturbances by policy induced shocks shifting the objective from price level variance to inflation variance the optimal policy produces much less volatile inflation at the cost of a unit root in the price level this is consistent with the stabilization of u s inflation after the gold standard was abandoned

us monetary policy and the euro area abstract this study documents empirically that contractionary us monetary policy may generate short term expansionary spillover effects in individual euro area ea member countries economic activity increases mainly via the trade channel also domestic credit and stock markets expand highlighting the importance of the financial channel however the international repercussions are transitory and distributed unevenly within the ea the effect diminishes as ea interest rates increase with a few quarters delay while the effects are heterogenous and rather large before 1999 responses become more homogeneous and smaller in size after the implementation of the euro still country specific asymmetries remain

the relationship between inflation and the budget deficit in turkey this article analyzes the empirical relationship between inflation and the budget deficit for the turkish economy by a multivariate cointegration analysis a single equation model shows that the scaled budget deficit as well as income growth and debt monetization significantly affects inflation in turkey the conditional model of inflation is constant and it encompasses a previously estimated model

german wage moderation and european imbalances feeding the global var with theory german labor market reforms in the 1990s and 2000s are generally believed to have driven the large increase in the dispersion of current account balances in the euro area we investigate this hypothesis quantitatively we develop a 3 region open economy new keynesian model with search and matching frictions from which we derive robust sign restrictions for wage bargaining and matching efficiency shocks which we term wage moderation shocks we impose these restrictions on a global var consisting of germany and 8 emu countries to identify a wage moderation shock in germany our results show that although the german current account was significantly affected by wage moderation shocks their contribution to european current account imbalances was negligible we conclude that the german labor market reforms cannot be the lone driver of european imbalances

inflation in open economies abstract this paper relates the time consistent inflation rate to the degree of trade openness of an economy the mechanism linking the welfare effects of monetary surprises and hence the incentives to inflate to openness does not rely on a large country terms of trade effect but rather is due to imperfect competition and nominal price rigidity in the non traded sector the empirical evidence supports the main predictions of the model 1997 elsevier science b v

fixed versus flexible exchange rates which provides more fiscal discipline abstract conventional wisdom holds that fixed rates provide more fiscal discipline than do flexible rates in this paper we show that this wisdom need not hold in a standard model in which fiscal policy is endogenously determined by a maximizing fiscal authority the claim that fixed rates induce more discipline stresses that sustained adoption of lax fiscal policies must eventually lead to an exhaustion of reserves and thus to a politically costly collapse of the peg hence under fixed rates bad behavior today leads to punishment tomorrow under flexible rates bad behavior has costs as well the difference is in the intertemporal distribution of these costs flexible rates allow the effects of unsound fiscal policies to manifest themselves immediately through movements in the exchange rate hence bad behavior today leads to punishment today if fiscal authorities are impatient flexible rates by forcing the costs to be paid up front provide more fiscal discipline and higher welfare for the representative private agent the recent experience of sub saharan countries supplies evidence that matches the predictions of the model

structural changes in the us economy is there a role for monetary policy this paper investigates the contribution of monetary policy to the changes in output growth and inflation dynamics in the us we identify a policy shock and a policy rule in at ime varying coefficients var using robust sign restrictions the transmission of policy shocks has been relatively stable the variance of the policy shock has decreased over time but policy shocks account for a small fraction of the level and of the variations in inflation and output growth volatility and persistence we find little evidence of a significant increase in the long run response of the interest rate to inflation a more aggressive inflation policy in the 1970s would have produced large output growth costs

fixed exchange rates and trade abstract a classic argument for a fixed exchange rate is its promotion of trade empirical support for this however is mixed while one branch of research consistently shows a small negative effect of exchange rate volatility on trade another more recent branch presents evidence of a large positive impact of currency unions on trade this paper helps resolve this disconnect our results which use a new data based classification of fixed exchange rate regimes show a large significant effect of a fixed exchange rate on bilateral trade between a base country and a country that pegs to it these results suggest an economically relevant role for exchange rate regimes in trade determination since a significant amount of world trade is conducted between countries with fixed exchange rates

the modern history of exchange rate arrangements a reinterpretation we develop a novel system of reclassifying historical exchange rate regimes one key difference between our study and previous classifications is that we employ monthly data on market determined parallel exchange rates going back to 1946 for 153 countries our approach differs from the imf official classification which we show to be only a little better than random it also differs radically from all previous attempts at historical reclassification our classification points to a rethinking of economic performance under alternative exchange rate regimes indeed the breakup of bretton woods had less impact on exchange rate regimes than is popularly believed

sufficient information in structural vars abstract necessary and sufficient conditions under which a var contains sufficient information to estimate the structural shocks are derived on the basis of this theoretical result we propose two simple tests to detect informational deficiency and a procedure to amend a deficient var a simulation based on a dsge model with fiscal foresight suggests that our method correctly identifies and fixes the informational problem in an empirical application we show that a bivariate var including unemployment and labor productivity is informationally deficient once the relevant information is included into the model technology shocks appear to be contractionary
