diversifying external linkages the exercise of irish economic sovereignty in long term perspective political independence is usually associated with an attempt to reduce economic dependency on the former dominant or colonial power for most of the early period since irish independence the attempt to reduce exposure to the uk was implemented through tariff protection and restrictions on foreign ownership inward orientation eventually ran out of steam culminating in sustained emigration and deep recession in the 1950s the genesis in the mid 1950s of ireland s low corporation tax regime facilitated later trade liberalization and diversified the economy away from the uk these developments facilitated the full convergence on uk and broader western european living standards that was eventually achieved in the 1990s from 1979 the uk would diverge from most of the rest of western europe on exchange rate policy and ireland was forced to choose between the two the resulting difficulties can be ascribed to design flaws in the european monetary project and ireland s failure to recognize the constraints that the new regime imposed

fiscal policy banks and the financial crisis this paper studies the effectiveness of euro area ea fiscal policy during the recent financial crisis using an estimated new keynesian model with a bank a key dimension of policy in the crisis was massive government support for banks that dimension has so far received little attention in the macroeconomics literature we use the estimated model to analyze the effects of bank asset losses of government support for banks and other fiscal stimulus measures in the ea our results suggest that support for banks had a stabilizing effect on ea output consumption and investment increased government purchases helped to stabilize output but crowded out consumption higher transfers to households had a positive impact on private consumption but a negligible effect on output and investment banking shocks and increased government spending explain half of the rise in the public debt gdp ratio since the onset of the crisis

political credit cycles the case of the euro zone we study the mechanisms through which the adoption of the euro delayed rather than advanced economic reforms in the euro zone periphery and led to the deterioration of important institutions in these countries we show that the abandonment of the reform process and the institutional deterioration in turn not only reduced their growth prospects but also fed back into financial conditions prolonging the credit boom and delaying the response to the bubble when the speculative nature of the cycle was already evident we analyze empirically the interrelation between the financial boom and the reform process in greece spain ireland and portugal and by way of contrast in germany a country that did experience a reform process after the creation of the euro

international capital flows and the boom bust cycle in spain we study the joint dynamics of foreign capital flows and real activity during the recent boom bust cycle of the spanish economy using a three country new keynesian model with credit constrained households and firms a construction sector and a government we estimate the model using 1995q1 2013q2 data for spain the rest of the euro area rea and the rest of the world we show that falling risk premia on spanish housing and non residential capital a loosening of collateral constraints for spanish households and firms as well as a fall in the interest rate spread between spain and the rea fuelled the spanish output boom and the persistent rise in foreign capital flows to spain before the global financial crisis during and after the global financial crisis falling house prices and a tightening of collateral constraints for spanish borrowers contributed to a sharp reduction in capital inflows and to the persistent slump in spanish real activity the credit crunch was especially pronounced for spanish households firm credit constraints tightened later and more gradually and contributed much less to the slump

computable markov perfect industry dynamics we provide a general model of dynamic competition in an oligopolistic industry with investment entry andexit toensurethatthereexistsacomputationallytractablemarkov perfectequilibrium we introduce firm heterogeneity in the form of randomly drawn privately known scrap values and setup costs into the model our game of incomplete information always has an equilibrium in cutoff entry exit strategies in contrast the existence of an equilibrium in the ericson and pakes model of industry dynamics requires admissibility of mixed entry exit strategies contrary to the assertion in their article that existing algorithms cannot cope with in addition we provide a condition on the model s primitives that ensures that the equilibrium is in pure investment strategies building on this basic existence result we first show that a symmetric equilibrium exists under appropriate assumptions on the model s primitives second we show that as the distribution of the random scrap values setup costs becomes degenerate equilibria in cutoff entry exit strategies converge to equilibria in mixed entry exit strategies of the game of complete information

fiscal policy in a financial crisis standard policy versus bank rescue measures a key dimension of fiscal policy during the financial crisis was massive government support for the banking system the macroeconomic effects of that support have so far received little attention in the literature this paper fills this gap using a quantitative dynamic model with a banking sector our results suggest that state aid for banks may have a strong positive effect on real activity bank state aid multipliers are in the same range as conventional fiscal spending multipliers support for banks has a positive effect on investment while a rise in government purchases crowds out investment

from sick man of europe to economic superstar germany s resurgent economy in the late 1990s and into the early 2000s germany was often called the sick man of europe indeed germany s economic growth averaged only about 1 2 percent per year from 1998 to 2005 including a recession in 2003 and unemployment rates rose from 9 2 percent in 1998 to 11 1 percent in 2005 today after the great recession germany is described as an economic superstar in contrast to most of its european neighbors and the united states germany experienced almost no increase in unemployment during the great recession despite a sharp decline in gdp in 2008 and 2009 germany s exports reached an all time record of 1 738 trillion in 2011 which is roughly equal to half of germany s gdp or 7 7 percent of world exports even the euro crisis seems not to have been able to stop germany s strengthening economy and employment how did germany with the fourth largest gdp in the world transform itself from the sick man of europe to an economic superstar in less than a decade we present evidence that the specific governance structure of the german labor market institutions allowed them to react flexibly in a time of extraordinary economic circumstances and that this distinctive characteristic of its labor market institutions has been the main reason for germany s economic success over the last decade

twin deficits squaring theory evidence and common sense in this paper we reconsider the twin deficit hypothesis that fiscal shocks generating budget deficits also worsen external trade both from a theoretical point of view and by analyzing data for australia canada the uk and the us first we assess the joint dynamics of budget and trade deficits along the business cycle uncovering a strikingly recurrent s shaped relation between the two the correlation is actually negative suggesting twin divergence this observation however cannot rule out the possibility that government spending expansions and or tax cuts may cause trade deficits as the overall correlation is likely to be dominated by cyclical factors second we reconsider the transmission of government spending in a standard two country two good model we find that openness and the persistence of fiscal shocks are major determinants of the magnitude or even sign of the response of the trade balance to fiscal shocks for a given persistence of the fiscal shock the closer an economy the larger the crowding out effect on investment the lower the deterioration of the trade balance third we take this insight to the data investigating the transmission of fiscal shocks in a var framework in the four countries in our sample our empirical findings tend to support our view in the us and australia which are relatively less open than canada and the uk and where government spending shocks are less persistent we find that the external impact of fiscal policy is rather limited instead private investment responds substantially the reverse is true for canada and the uk these findings confirm and put into perspective earlier results whereas fiscal expansions in the us are found to have on average a negligible effect on the country s trade balance however we emphasize that these results are consistent with a call for a us fiscal retrenchment to address global imbalances the impact of budget cuts on the us external trade is muted by their positive effect on domestic investment strengthening the us ability to generate resources against future interest and debt repayment

productivity shocks budget deficits and the current account abstract productivity shocks and budget deficits are considered to be two key determinants of the current account in order to assess formally the role of both factors in driving current account movements the present paper extends the standard intertemporal model of the current account to allow for non ricardian household behavior testable cross equation restrictions for the current account and investment are derived by drawing on the distinction between country specific and global innovations to productivity as well as to the government budget we test the restrictions of the model against time series data for 21 oecd countries and find evidence in support of the model

us trade balance dynamics the role of fiscal policy and productivity shocks and of financial market linkages abstract this paper examines whether domestic and foreign productivity and fiscal policy changes can account for the wide swings in us net exports during the period 1975 1991 a two country real business cycle model is used for that purpose the model is simulated using data on productivity government purchases and taxes for the g7 countries a version of the model with incomplete asset markets in which only bonds can be used for international capital flows tracks the us trade balance fairly closely provided permanent country specific productivity shifts are assumed the simulations suggest that us productivity changes were the main source of fluctuations in us net exports

dissecting the dynamics of the us trade balance in an estimated equilibrium model in an estimated two country dsge model we find that efficiency shocks specific to investment account for more than half of the forecast variance of cyclical fluctuations in the us trade balance both domestic and foreign investment specific shocks have a substantial impact on the variability of the imbalance total factor productivity shocks do not matter for the variance and even lead to procyclicality in the trade balance

welfare effects of a monetary union the role of trade openness this paper evaluates the welfare effects of a monetary union mu compared to a e oating exchange rate regime using a quantitative business cycle model of a two country world with sticky prices it is assumed that under a e oat there are shocks to the uncovered interest rate parity uip condition these shocks are shown to have a negative effect on welfare the detrimental effect is stronger the higher the degree of trade openness a mu eliminates uip shocks and it may thus raise welfare the welfare gain from mu is positively linked to openness jel e4 f3 f4

the exchange rate in a dynamic optimizing business cycle model with nominal rigidities a quantitative investigation this paper studies a quantitative dynamic optimizing business cycle model of a small open economy with staggered price and wage setting the model exhibits exchange rate overshooting in response to money supply shocks the predicted variability of the nominal and especially of the real exchange rate is noticeably higher than in standard real business cycle models with flexible prices and wages a positive domestic money supply shock is predicted to lower the domestic interest rate raise gdp and trigger a depreciation of both the nominal and real exchange rate increases in domestic productivity and in the world interest rate are also predicted to induce a nominal and real exchange rate depreciation 2001 elsevier science b v all rights reserved

investment shocks and business cycles abstract the origins of business cycles are still controversial among macroeconomists this paper contributes to this debate by studying the driving forces of fluctuations in an estimated new neoclassical synthesis model of the u s economy in this model most of the variability of output and hours at business cycle frequencies is due to shocks to the marginal efficiency of investment imperfect competition and to a lesser extent technological frictions are the key to their transmission although labor supply shocks explain a large fraction of the fluctuations in hours at very low frequencies they are irrelevant over the business cycle this finding is important because the microfoundations of these disturbances are widely regarded as unappealing

five facts about prices a reevaluation of menu cost models are price decreases 3 the frequency of price increases covaries strongly with inflation whereas the frequency of price decreases and the size of price increases and price decreases do not 4 the frequency of price change is highly seasonal it is highest in the first quarter and then declines 5 we find no evidence of upwardsloping hazard functions of price changes for individual products we show that the first second and third facts are consistent with a benchmark menu cost model whereas the fourth and fifth facts are not

stickiness synchronization and passthrough in intrafirm trade prices about forty percent of all u s international trades occurs between related parties or intra rm such as trades between a parent and subsidiary of the same multinational corporation this paper uses a transaction level dataset that distinguishes arm s length

state dependent or time dependent pricing does it matter for recent u s inflation in the 1988 2004 micro data collected by the u s bureau of labor statistics for the cpi price changes are frequent every 4 7 months depending on the treatment of sale prices and large in absolute value on the order of 10 the size and timing of price changes varies considerably for a given item but the size and probability of a price change are unrelated to the time since the last price change movements in aggregate inflation reflect movements in the size of price changes rather than the fraction of items changing price due to offsetting movements in the fraction of price increases and decreases neither leading time dependent models taylor or calvo nor 1 st generation state dependent models match all of these facts some 2 nd generation state dependent models however appear broadly consistent with the empirical patterns

is firm pricing state or time dependent evidence from u s manufacturing abstract if pricing is state dependent firms are more likely to adjust whenever aggregate and idiosyncratic shocks reinforce each other and trigger desired price changes in the same direction using measures of technology shocks derived from production function estimates for four digit u s manufacturing industries i find that sectoral inflation rates are more sensitive to negative as opposed to positive technology disturbances in periods of higher economy wide inflation commodity price increases and expansionary monetary policy shocks i argue using a state dependent sticky price model that matches salient features of the u s microprice data that these results suggest that pricing is state dependent in u s manufacturing

the recent boom bust cycle the relative contribution of capital flows credit supply and asset bubbles abstract we use an estimated open economy dsge model with financial frictions for the us and the rest of the world to evaluate various competing explanations about the recent boom bust cycle we find that the savings glut hypothesis is insufficient for explaining all aspects of the boom in the us relatively strong tfp growth and expansionary monetary policy are also not able to explain fully the volatility of corporate and in particular residential investment we identify bubbles in the stock and housing market as crucial concerning the downturn in 2008 2009 the fall in house prices and residential investment only plays a minor role mortgage defaults have more explanatory power especially in a specification of the model with a segregated equity market finally the bursting of the stock market bubble was at least as important in this recession as in 2001 because of various negative shocks hitting the economy at the same time in 2008 2009 and continued positive technology growth not only the real interest rate declined but inflation fell rapidly and left insufficient room for monetary policy to play a similar stabilising role as in previous recessions

current accounts and financial flows in the euro area abstract we construct a new database of bilateral financial flows among euro area countries and their major world partners and explore the role of financial links in the accumulation and then adjustment of current account imbalances in the euro area the data show that the geography of financial flows can differ quite markedly from trade flow patterns and suggest that the nexus between surpluses in the core with deficits in the periphery went along financial rather than trade interlinkages in particular the data document the dominant role of core countries in financing the euro area periphery s current account deficits before the financial crisis both directly and through intermediating financial flows from outside of the euro area most of this financing took the form of debt instruments following the withdrawal of private financing from core countries during the crisis the ecb mediated funding and other official flows helped the periphery to refinance its liabilities and smoothen the external adjustment

a state dependent model of intermediate goods pricing recent analyses of transaction level datasets have generated new stylized facts on price setting and greatly influenced the empirical macroeconomics literature this work has uncovered marked heterogeneity in price stickiness demonstrated that even non zero price changes do not fully pass through cost shocks and offered evidence of synchronization in the timing of price changes further intrafirm prices have been shown to differ from arm s length prices in each of these characteristics this paper develops a state dependent model of intermediate goods pricing which allows for arm s length and intrafirm transactions and is capable of generating these empirical pricing patterns

what drives the german current account and how does it affect other eu member states we estimate a three country model using 1995 2013 data for germany the rest of the euro area rea and the rest of the world row to analyse the determinants of germany s current account ca surplus after the launch of the euro our results suggest that the german surplus reflects a succession of distinct shocks mono causal explanations of the surplus are thus insufficient the most important factors driving the german surplus were positive shocks to the german saving rate and to row demand for german exports as well as german labour market reforms and other positive german aggregate supply shocks the key shocks that drove the rise in the german ca tended to worsen the rea trade balance but had a weak effect on rea real activity our analysis suggests these driving factors are likely to be slowly eroded leading to a very gradual reduction of the german ca surplus an expansion in german government consumption and investment would raise german gdp and reduce the ca surplus but the effects on the surplus would be weak

the effects of government purchases shocks review and estimates for the eu in this article we review the theoretical consequences of government purchases shocks for both closed and open economies followed by a discussion of the empirical literature next we provide our own estimates for the eu countries we find that an increase in government purchases raises output consumption and investment and reduces the trade balance however the stimulating effect is weaker and the trade balance reduction is larger for the more open eu economies consistent with larger leakage effects further we show that government purchases shocks in large eu economies have non negligible consequences for economic activity in the main trading partners

monetary non neutrality in a multisector menu cost model empirical evidence suggests that as much as one third of the u s business cycle is due to nominal shocks we calibrate a multisector menu cost model using new evidence on the cross sectional distribution of the frequency and size of price changes in the u s economy we augment the model to incorporate intermediate inputs we show that the introduction of heterogeneity in the frequency of price change triples the degree of monetary non neutrality generated by the model we furthermore show that the introduction of intermediate inputs raises the degree of monetary non neutrality by another factor of three without adversely affecting the model s ability to match the large average size of price changes a single sector model with a frequency of price change equal to the median rather than the mean generates monetary non neutrality similar to that in our multisector model our multisector model with intermediate inputs generates variation in real output in response to calibrated aggregate nominal shocks that can account for roughly 23 of the u s business cycle

sticky prices in a dynamic oligopoly an investigation of s s thresholds abstract the strategic implications of costly price adjustment are investigated empirically i assume that managers are engaged in a state space game and ask if the dynamic considerations that arise when they condition their choices on the state cause prices to be more or less rigid than when players use more myopic pricing rules the answer to this question depends on a parametric specification of the problem that lends itself to empirical assessment the micro panel data used to investigate this issue consist of weekly prices sales costs and promotional activity for three brands of saltine crackers sold by four chains of grocery stores in a small us town i find that in this market strategic behavior exacerbates price rigidity the thresholds are wider and the time between changes is longer than would be observed in a more myopic setting

the effect of holdings data frequency on conclusions about mutual fund behavior abstract a number of articles in financial economics have used quarterly or semi annual mutual fund holdings data to test hypotheses about investment manager behavior this article reexamines four well known hypotheses in finance to determine whether the results of prior tests of these hypotheses remain valid when higher frequency monthly holdings data are employed the areas examined are momentum trading tax motivated trading window dressing and tournament behavior we find that the use of monthly holdings data rather than quarterly holdings data or in the case of tournament behavior holdings data rather than monthly return data change and in some cases reverse previous results this occurs because monthly holdings data capture a large number of trades missed by quarterly data 18 5 of the trades and permit a more precise estimation of the timing of trades

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

a reconsideration of the uncovered interest parity relationship abstract this paper argues that the uncovered interest parity uip relationship is distinct from and more important than the unbiasedness of forward exchange rates as predictors of future spot rates the standard finding that the slope estimate b is roughly 3 in regressions of s t on t 1 s t 1 implies rejection of unbiasedness but not necessarily uip the hypothesis that monetary authorities manage interest rates so as to smooth their movements while also resisting changes in exchange rates is attractive conceptually and is capable of explaining not only the b 3 finding but also several other notable features of the data

state dependent pricing and the general equilibrium dynamics of money and output economists have long suggested that nominal product prices are changed infrequently because of fixed costs in such a setting optimal price adjustment should depend on the state of the economy yet while widely discussed statedependent pricing has proved difficult to incorporate into macroeconomic models this paper develops a new tractable theoretical state dependent pricing framework we use it to study how optimal pricing depends on the persistence of monetary shocks the elasticities of labor supply and goods demand and the interest sensitivity of money demand

frequency of price adjustment and pass through we empirically document using u s import prices that on average goods with a high frequency of price adjustment have a long run pass through that is at least twice as high as that of low frequency adjusters we show theoretically that this relationship should follow because variable mark ups that reduce long run pass through also reduces the curvature of the proflt function when expressed as a function of the cost shocks making the flrm less willing to adjust its price lastly we quantitatively evaluate a dynamic menu cost model and show that the variable mark up channel can generate signiflcant variation in frequency equivalent to 37 of the observed variation in the data on the other hand the standard workhorse model with constant elasticity of demand and calvo or state dependent pricing has di culty matching the facts

convergence and anchoring of yield curves in the euro area we study the convergence of european bond markets and the anchoring of inflation expectations in the euro area using high frequency bond yield data for france germany italy and spain as well as smaller euro area countries and a control group comprising the uk denmark and sweden we find that economic and monetary union emu has led to substantial convergence in euro area sovereign bond markets in terms of interest rate levels unconditional daily fluctuations and conditional responses to major macroeconomic announcements our findings also suggest a substantial increase in the anchoring of long term inflation expectations since emu particularly for italy and spain which have seen their long term interest rates become much lower much less volatile and much better anchored in response to news finally we present evidence that the elimination of exchange rate risk and the adoption of a common monetary policy were the primary drivers of bond market convergence in the euro area as opposed to fiscal policy restraint and the loose exchange rate peg of the 1990s jel no e52 e58

the dynamic effects of neutral and investment specific technology shocks the neoclassical growth model is used to identify the short run effects of neutral technology shocks which affect the production of all goods homogeneously and investment specific shocks which affect only investment goods the real equipment price crucial for identifying the investment shocks experiences an abrupt increase in its average rate of decline in 1982 so the analysis is based on a split sample on the basis of the preferred specification the two technology shocks account for 73 percent of hours and 44 percent of output s business cycle variation before 1982 and 38 percent and 80 percent afterward the shocks also account for more than 40 percent of hours and 58 percent of output s forecast errors over a three to eight year horizon in both samples the majority of these effects are driven by the investment shocks

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite

has the euro changed the business cycle abstract in contrast to the notion that the exchange rate regime is non neutral there is little evidence that emu has systematically changed the european business cycle in fact we find the volatility of macroeconomic variables largely unchanged before and after the introduction of the euro exceptions are a strong decline in real exchange rate volatility and a considerable increase in cross country correlations to account for this finding we develop a two country business cycle model which is able to replicate key features of european data in particular the model correctly predicts a limited effect of emu on standard business cycles statistics however further analysis reveals that the euro has changed the nature of the cycle through its impact on the transmission mechanism cross country spillovers have become relatively more domestic shocks relatively less important in accounting for economic fluctuations under emu this explains why there is little change in unconditional volatilities

does the current account still matter do global current account imbalances still matter in a world of deep international financial markets where gross two way financial flows often dwarf the net flows measured in the current account contrary to a complete markets or consenting adults view of the world large current account imbalances while very possibly warranted by fundamentals and welcome can also signal elevated macroeconomic and financial stresses as was arguably the case in the mid 2000s furthermore the increasingly big valuation changes in countries net international investment positions while potentially important in risk allocation cannot be relied upon systematically to offset the changes in national wealth implied by the current account the same factors that dictate careful attention to global imbalances also imply however that data on gross international financial flows and positions are central to any assessment of financial stability risks the balance sheet mismatches of leveraged entities provide the most direct indicators of potential instability much more so than do global imbalances though the imbalances may well be a symptom that deeper financial threats are gathering
