wage bargaining central bank independence and the real effects of money the effects of financial capital mobility on monetary policy autonomy are relatively well understood but the importance of particular monetary regimes in distinct national institutional settings is not this article is a theoretical and empirical exploration of the effects of monetary policy regimes on unemployment in different national wage bargaining settings based on a rational expectations two stage game of the interaction between the wage behavior of labor unions and the monetary policies of governments i argue that monetary policies have real employment effects in all but the most decentralized bargaining systems specifically in intermediately centralized bargaining systems a credible government commitment to a nonaccommodating monetary policy rule will deter militant wage behavior with salutary effects on unemployment in highly centralized systems by contrast restrictive monetary policies will clash with unions pursuit of wage distributive goals and produce inferior employment performance only in highly fragmented bargaining systems is money neutral in the sense that employment performance is unaffected by monetary regimes the model has clear consequences for the optimal design of central banks and collective bargaining arrangements and suggests new ways to study institutional change hereunder the causal effect of increasingly globalized capital markets the argument is supported by pooled time series data for fifteen oecd countries over a twenty one year period

examining quantity and quality effects of restricting nitrogen applications to feedgrains restricting the timing and level of nitrogen applications has been proposed as a response to nitrate contamination in nebraska agronomic research indicates that reducing available nitrogen reduces both the yield quantity and protein content quality of feedgrains a differential system is developed to estimate the social costs of regulation while simultaneously considering both quantity and quality effects of a tax and or a rationing policy the results indicate that ignoring the quality effects of a proposed policy can lead to erroneous estimates of changes in factor use output responses and the social costs of regulation

economics in the backyard how much convergence is there between china and her special regions this paper tests the hypothesis that the links and dependency relationships between china and her special regions have changed over the past 20 years with the industrialisation of china and the emergence of taiwan as a source of investment and sophisticated manufactures and hong kong as financial centre and supplier of services has this changed the size and direction of spillovers in the region and has it curtailed or eliminated american economic leadership we use time varying spectral methods to decompose the links between six advanced asian economies and the us we find a the links with the us have been weakening while those within a bloc based on china have strengthened b that this is not new it has been happening since the 1980s but has now been reversed by the surge in trade c that taiwan is more integrated with and dependent on the chinese economy while hong kong continues her separate development based on specialisation and comparative advantage d that the links with the us are rather complex with the us able to shape the cycles elsewhere through her control of monetary conditions but the china zone able to control the size of their cycles and e there appears to be no real evidence that pegged exchange rates encourage convergence in fact the reverse may be true

trade finance specialization and synchronization i investigate the determinants of business cycle synchronization across regions the linkages between trade in goods financial openness specialization and business cycle synchronization are evaluated in the context of a system of simultaneous equations the main results are as follows i specialization patterns have a sizable effect on business cycles most of this effect is independent of trade or financial policy but directly reflects differences in gdp per capita ii a variety of measures of financial integration suggest that economic regions with strong financial links are significantly more synchronized even though they also tend to be more specialized iii the estimated role of trade is closer to that implied by existing models once intra industry trade is held constant the results obtain in a variety of data sets measurement strategies and specifications they relate to a recent strand of international business cycle models with incomplete markets and transport costs and on the empir

interest rates and currency prices in a two country world abstract this paper is a theoretical study of the determination of prices interest rates and currency exchange rates set in an infinitely lived two country world which is subject both to stochastic endowment shocks and to monetary instability formulas are obtained for pricing all equity claims nominally denominated bonds and currencies and these formulas are related to earlier closely related results in the theories of money finance international trade

international portfolio nondiversification and exchange rate variability abstract incomplete international portfolio diversification is implied by an equilibrium models of exchange rates with nontraded goods the model can also explain the greater correlation between consumption and income within a country than between consumption across countries nontraded goods make more stringent the elasticity conditions required to explain exchange rate variability resulting from current productivity disturbances though not from disturbances to fiscal policies or the prospective return to investment the model is also consistent with international real interest rate differentials changes over time in the current account and relative wealth across nations and observed time series properties of exchange rates

commodity trade and international risk sharing how much do financial markets matter abstract this paper evaluates the social gains from international risk sharing in some simple general equilibrium models with output uncertainty a simulation model calibrated to selected moments of u s and japanese data estimates the incremental loss from a ban on international portfolio diversification to be on the order of 0 20 percent of output per year even the theoretical gains from asset trade may disappear under alternative sets of assumptions on preferences and technology the paper argues that the small magnitude of potential trade gains may help explain the apparently inconsistent findings of empirical studies on the degree of international capital mobility

borders and business cycles abstract we document that business cycles of u s census regions are substantially more synchronized than those of european countries data from regions within european countries confirm a european border effect within country correlations are substantially larger than cross country correlations these results continue to hold after controlling for exogenous factors such as distance and size we consider the role of four factors that have received attention in the debate about emu sectoral specialization the level of trade monetary policy and fiscal policy we find that the lower level of trade between european countries explains most of the observed border effect

federal reserve operating procedures a survey and evaluation of the historical record since october 1979 comment william poole has produced another thoughtful and thought provoking paper two major conclusions emerge from his work first the instability of growth in m1b since october 1979 can be attributed largely to a reluctance by the federal reserve to permit wide enough swings in the federal funds rate second to correct this problem and to promote greater stability in financial markets and the economy the fed ought to replace lagged with contemporaneous reserve accounting and reform the discount window they should then begin to hit a nonborrowed base or reserves target that grows at a steady rate i will organize my comments around these two conclusions i will not comment directly on the other excellent paper in this session by ralph c bryant i will refer to some of bryant s empirical work though in my discussion of the poole paper poole attributes the continued extensive volatility of m1b growth since october 1979 to efforts by the federal reserve to smooth interest rates he concedes that the fed really has let go the federal funds rate to a very considerable extent but he believes that variability in m1b growth over tonger periods is due primarily to the important role accorded interest rates in federal reserve policy making italics mine he cites four reasons for believing that the post october 1979 targeting procedures qualitatively are not very different from the federal funds targeting procedure followed earlier of the four the most interesting and empirically verifiable is that in nearly one third of the weeks since october 1979 the federal funds rate has averaged within 100 basis points of either the bottom or the top of the widened target range during these weeks the constraint on the funds rate might have prevented the fed from hitting its nonborrowed reserves target poole in fact accepts this view uncritically

organized labor and the political economy of product market distortions why are economic reforms reversed through strikes and demonstrations in some countries but backed by the labor movement in other countries why do product and labor market distortions differ so much across countries this article addresses these questions by means of a simple heuristic model of the economy that replicates in an integrated manner several independent results from the recent political economy literature unlike most of this literature however the model focuses on the role played by organized labor rather than by rent seeking firms and guilds a two stage game between the government and organized labor determines the level of product market distortions for example import tariffs in the first stage the players may undertake costly actions such as redistributing income or striking in order to increase their bargaining power in the second stage they negotiate over product market distortions and wages under very general assumptions several policy regimes exist changes in the key parameters of the economy may trigger a switch in the strategy of trade unions from confrontation to cooperation and hence change the policy regime cross country data highlight that in spite of its simplicity the model reproduces some observed empirical regularities

exchange rate policy wage formation and credibility abstract since the collapse of the bretton woods system some european countries have pursued discretionary exchange rate policies in order to maintain or enhance the international competitiveness of the traded goods sector these countries which typically feature centralized wage setting have also tended to experience high nominal wage increases the overall outcome may be described as a devaluation wage spiral this paper applies two models of repeated games to analyze the strategic interaction between an exchange rate setting policy maker and a wage setting trade union it is shown how a devaluation wage spiral may result from a conflict of interest over the real wage it is also shown how reputational forces may provide a way out of the devaluation wage spiral

international debt and world business fluctuations abstract the international transmission of real productivity disturbances is examined in an optimizing model with two countries each inhabited by an infinitely lived representative consumer producer we analyze the dynamics of output consumption investment interest rates and net external debt foreign productivity shocks can have positive or negative impacts on domestic output and international debt depending on the intertemporal distribution of the shocks transient foreign shocks are shown to be positively transmitted and lead to increased domestic indebtedness while permanent foreign shocks are negatively transmitted and lead to a decline in domestic indebtedness

a new approach to decomposition of economic time series into permanent and transitory components with particular attention to measurement of the business cycle abstract this paper introduces a general procedure for decomposition of non stationary time series into a permanent and transitory component allowing both components to be stochastic the permanent component is shown to be a random walk with drift and the transitory or cyclical component is a stationary process with mean zero the decomposition methodology which depends only on past data and therefore is computable in real time is applied to the problem of measuring and dating business cycles in the portwar u s economy we find that measured expansions and contractions are of roughly equivalent duration and that our dating of cyclical episodes tends to lead the traditional nber dating and to a lesser extent the growth cycle chronology of zarnowitz and boschan 1977

trade integration and business cycle convergence is the relation robust across time and space in this paper we investigate the relationship between trade intensity and the business cycle correlation using a panel data set taken from 24 countries over the period 1959 2003 most previous studies did not account for the possibility that the business cycle correlation may be influenced by unobservable country pair specific effects our estimates using both fixed and random effects methodologies suggest that trade intensity and the business cycle correlation are positively related to one another however detailed investigation shows that this relationship exists mainly for the european countries

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

macroeconomic policy with a floating exchange rate and a unionized nontraded sector this paper considers the effect of a unionized nontraded sector on welfare and policy in an open economy in equilibrium there are endogenous wage and price setting there may be unemployment and non walrasian policy effects nominal wages and prices become pegged to the price of tradables with direct government employment the multiplier is unity irrespective of financing with direct government expenditure on nontradables the multiplier is less than unity in both cases an increase in government expenditure reduces welfare

tariffs employment and the current account real wage resistance and the macroeconomics of protectionism using a standard complete specialization model of a small open economy within a rigorous intertemporal optimization framework and with contract based wage rigidity we show that permanent tariffs lead to a current account deterioration and a fall in employment contradicting most of the literature on macroeconomic effects of import tariffs the crucial factor in this complete reversal of standard results is the impact of tariffs on domestic real product wages via wage indexation temporary tariffs will have less of a negative impact on the ca or potentially even a positive impact because they increase the consumption rate of interest the terms at which future consumption can be traded for current consumption and so increase private savings extensions towards incorporating a more general production structure investment and the use of tariff revenues to provide wage subsidies are presented this abstract was borrowed from another version of this item

is it harmful to allow partial cooperation in economics politics and society examples abound in economics politics and society where agents can enter partial cooperation schemes i e they can collude with a subset of agents several contributions devoted to specific settings have claimed that such partial cooperation actually worsens welfare compared to the no cooperation situation our paper assesses this view by highlighting the forces that lead to such results we find that the nature of strategic spillovers is central to determining whether partial cooperation is bad our propositions are then applied to various examples as industry wage bargaining or local public goods

a real model of the world business cycle abstract in this paper a stochastic two country log linear infinite horizon model is used to analyze the generation and transmission of economic fluctuations across countries it is argued that following a country specific supply disturbance production interdependence and unitary elasticities in consumption and production are sufficient to generate comovements in aggregate economic activity investment and trade that are persistent over time and positively correlated across countries however the empirical analysis carried out for the usa japan germany and uk for the 1960 82 period suggests that common shocks rather than trade links are responsible for this pattern of comovements

international capital movements and the locomotive effect abstract in this paper we build a two country two good model in which domestic and foreign investment goods are perfect or imperfect substitutes and the utilization rate of capital is variable if investment goods are imperfect substitutes the model succeeds in mimicking the output cross country correlation in particular a country specific technological shock leads to an increase in output in the two countries which reveals a locomotive effect thus substitution elasticity between domestic and foreign investment goods is a key parameter of the international transmission of the business cycle in the model

world business cycles under fixed and flexible exchange rates this paper studies the behavior of monthly industrial production indices during the recent periods of fixed and flexible exchange rate s the central conclusions are as follows industrial production indices are subject to stochastic trend growth the variances of the monthly growth rates are higher in the flexible exchange rate period than in the fixed exchange rate period and are related to the degree of openness and to national income more open economies tend to experience more variability while richer more diversified economies experience less and output movements have been correlated across countries under both exchange rate regimes and there is evidence of a world business cycle copyright 1988 by ohio state university press

does trade integration cause convergence abstract using a business cycle model we analyse the conditions for trade integration to produce economic convergence we find large stable economies with integrated structures are likely to diverge but smaller more volatile or less well integrated economies will converge the symmetry of shocks is unimportant

regional and outward economic integration in south east asia the subject of this article tackles macroeconomic integration of the south east asian countries south korea singapore and taiwan economically the analysis is based on notions of stochastic long run convergence and business cycle synchrony in the gross domestic products gdps relevant tests for cointegration and common serial correlation features reveal a high degree of coherence in long run growth and medium run fluctuations this allows extracting a common stochastic growth trend and a common business cycle further analysis shows that both these components are subject to stronger influences from the us than from japan convergence towards these matured economies conspicuously appears since the 1990s

bargaining structure and economic performance in the open economy abstract it seems nowadays accepted that both centralized wage bargaining and negotiation at the firm level perform better than sectoral wage bargaining this is because sectoral unions have enough market power to raise wages but do not internalize all the effects of their actions however the ranking may be different in an open economy facing a less than infinitely elastic foreign demand because raising wages improves the country s terms of trade as in the optimal tariff argument as a result welfare is higher in the centralized setting while sectoral bargaining is better than full decentralization when imported goods represent a large share of total consumption

relative prices in monetary union and floating we analyse a small open economy with a tradable and a sheltered sector if the unions that operate in each sector coordinate their wage demands sectorwise the choice of monetary regime floating cum inflation target vs emu may affect the relative wages and prices of the economy we show that emu results in lower prices for tradable goods and lower real wages in the traded sector while opposite results hold for sheltered sector prices and wages thus if large unions behave strategically the choice of monetary regime has far reaching structural implications

macroeconomic performance and wage setting level in symmetric non cooperative games abstract this paper shows that the relationship between the wage and the extent of centralisation of the wage setting is necessarily monotonic in symmetric non cooperative games between monopoly trade unions if the game for each wage setting level has only one equilibrium moreover when the conditions of stability of nash equilibria are fulfilled the trade unions welfare rises with the degree of centralisation

input substitution and the distribution of surplus gains from lower u s beef processing costs the impact on consumers and input suppliers of allowing substitution between farm and nonfarm inputs in food processing is a controversial issue freebairn davis and edwards 1982 assumed that no substitution between these inputs was possible and concluded that the distribution of surplus gains between producers and consumers is independent of the source of supply shift alston and scobie pointed out that this conclusion depends on the assumption of no input substitution once input substitution is possible farmers can no longer be indifferent about the supply shift since their share of total surplus gains is greater for shifts in farm supply than for marketing input supply furthermore as the degree of input substitution increases the farmers share of surplus gains from a downward shift in the supply of marketing inputs decreases freebairn davis and edwards 1983 replied that while we tend to agree with alston and scobie that the elasticity of substitution in the case of pork is likely to be nonzero we doubt that it is very large and at this stage no satisfactory estimate is available p 357 in this study we obtain a lower bound estimate of the elasticity of substitution and show

monopolistic competition and the effects of aggregate demand how important is monopolistic competition to an understanding of the effects of aggregate demand on output we ask the question at three levels can monopolistic competition by itself explain why aggregate demand movements affect output can it together with other imperfections generate effects of aggregate demand in a way that perfect competition cannot if so can it give an accurate account of the response of the economy to aggregate demand movements the answers are no yes and yes

the role of international factors in the business cycle a multi country study abstract empirical research has been conducted on the various theories of the business cycle over many countries however very little research has attempted to undertake a multi country disaggregate investigation into the sources of output change this paper decomposes fluctuations in industry output in a particular country into 1 a nation specific shock 2 an industry specific shock 3 a common shock and 4 an idiosyncratic factor using a dynamic factor analysis state space approach the paper finds that the industry specific impulse explains a significant but small part of the variance of the forecast error this provides limited support for the disaggregated real business cycle paradigm

business cycles and the exchange rate system some international evidence this paper investigates the differences in time series behavior of key economic aggregates under alternative exchange rate systems we use a postwar sample of 49 countries to compare the behavior of output consumption trade flows government consumption spending and real exchange rates under alternative exchange rate systems pegged floating and cooperative systems such as the ems we then examine evidence from two particular episodes involving canada and ireland of changes in the exchange rate system aside from greater variability of real exchange rates under flexible than under pegged nominal exchange rate systems we find little evidence of systematic differences in the behavior of macroeconomic aggregates or international trade flows under alternative exchange rate systems these results are of interest because a large class of theoretical models implies that the nominal exchange rate system has important effects on a number of macroeconomic quantities

business cycle correlations in asia pacific abstract in this paper business cycle correlations between countries in the asia pacific region are examined trade intensity and a number of other macroeconomic and structural variables are used to try and explain synchronisation the findings suggest that trade does not explain correlations in the asia pacific region

a currency union for hong kong and mainland china abstract this paper investigates the degree and the evolution of business cycle synchronization between hong kong sar and mainland china as well as hong kong sar and the united states with a two step procedure a structural var model is first set up to capture the dynamics of shocks to different regions then a state space model is used to gauge the degree of symmetry of regional shocks and to examine whether business cycles have been more synchronized over time our results cast doubt on the feasibility of a currency union between hong kong and mainland china in the foreseeable future

trade interdependence and the international business cycle a stochastic general equilibrium model of the world economy is developed to analyze the contribution of trade interdependence to international business cycles we test some of the implications of the model using data from ten major industrial countries and a variety of detrending techniques to calculate the cyclical component of output we find that the significance of trade in the transmission of economic disturbances across countries is not robust to the choice of the detrending method in general the role of trade interdependence is moderate and seem to have been stronger in the period before 1973

sources and propagation of international output cycles common shocks or transmission abstract this paper studies the generation and transmission of international cycles in a multi country model with production and consumption interdependencies two sources of disturbance are considered and three channels of propagation are compared technology disturbances which are mildly correlated across countries are more successful than government expenditure disturbances in reproducing actual data the presence of a common component to the shocks and of production interdependencies appear to be crucial in quantitatively matching the properties of the data

how do the trans pacific economies affect the usa an industrial sector approach this paper studies how the trans pacific region affects the us economy in terms of business cycle transmission we use a large data set consisting of disaggregated sectoral industrial production indexes from selected countries in the region and employ a factor augmented vector autoregression favar approach to analyse the transmission of shocks in different industries we find that a positive output shock in the entire trans pacific region has positive effects on the majority of us manufacturing sectors we also find that sectoral shocks in five sectors of the trans pacific region have a large impact on the overall us economy three of the five sectors displayed strong same sector responses relative to the overall response suggesting that vertical production linkages might play a key role in the transmission of shocks our results highlight the importance of examining industrial sectors in studying the transmission of shocks in the trans pacific region

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

capital flows investment and exchange rates abstract this paper incorporates international capital flows into a two country monetary general equilibrium model of asset prices with investment and production we calculate theoretical covariances between investment the current account the exchange rate and the terms of trade these covariances depend upon the coefficient of relative risk aversion the magnitude and sign of a country s net international indebtedness other properties of tastes and technologies and the stochastic processes on disturbances to productivity and monetary growth rates international capital flows arise from changes in world wealth and its relative composition in foreign and domestic assets

central bank independence centralization of wage bargaining inflation and unemployment theory and some evidence abstract this paper proposes a conceptual framework to investigate the effects of central bank independence of the degree of centralization of wage bargaining and of the interaction between those institutional variables on real wages unemployment and inflation in a framework in which unions are averse to inflation this aversion moderates union s wage demands as they attempt to induce the central bank to inflate at a lower rate an increase in the degree of centralization of wage bargaining a decrease in the number of unions triggers two opposite effects on real wages unemployment and inflation it reduces the substitutability between the labor of different unions and therefore the degree of effective competition between them this reduced competition effect raises real wages unemployment and inflation but the decrease in the number of unions also strengthens the moderating effect of inflationary fears on the real wage demands of each union this strategic effect lowers real wages unemployment and inflation for sufficiently inflation averse unions the interaction between those two effects produces a calmfors driffill type relation between real wages and centralization the paper analyzes the effects of central bank independence on the position and the shape of this relation as well as on inflation and unemployment the paper features two mechanisms one of which is novel through which monetary institutions have real effects the model implies that if there is a single union social welfare is maximized when the central bank attaches a zero weight to inflation but when the number of unions is larger than one this result is no longer true in general empirical evaluation of some of the theoretical implications using data from 19 developed economies is for the most part supportive of those implications
