monetary policy rules in the open economy effects on welfare and business cycles abstract this paper computes welfare maximizing taylor style interest rate rules in a business cycle model of a small open economy the model assumes staggered price setting and shocks to domestic productivity to the world interest rate to world inflation and to the uncovered interest rate parity condition optimized policy rules have a pronounced anti inflation stance and entail significant nominal and real exchange rate volatility the country responds to an increase in external volatility by holding more foreign assets the policy rule affects the variance and the mean of consumption the effect on the mean matters significantly for welfare

exchange rate regimes and the international transmission of business cycles capital account openness matters abstract we investigate the role of exchange rate regimes in the international transmission of business cycles during the global financial crisis we find that exchange rate regimes alone did not account for differences in the international transmission of business cycles during the crisis however analysis considering capital account openness and countries with currencies pegged to the u s dollar indicates that exchange rate regimes play an important role in shaping business cycle co movement adopting a fixed regime with high capital account openness additionally increased business cycle co movement with the united states during the crisis whereas u s dollar peggers with relatively restrictive capital accounts during the crisis were not found to affect business cycle transmission

concentration diversification and earnings instability some evidence on developing countries exports of manufactures and primary products policies aimed at diversification of the commodity composition of exports continue to be advocated as a means of reducing instability in ldcs export earnings the usual assumptions are that earnings from manufactures are more stable than earnings from primary products and that diversification will reduce the covariances between earnings from different pairs of products it is suggested here that for several reasons these assumptions may not be valid evidence is then presented which indicates that across a sample of countries diversification has taken place but has not been accompanied by relatively greater stability in manufactures and favourable changes in covariances

portfolio optimisation and the design of latin american export diversification policies this article applies portfolio optimisation analysis to assess the risk and return characteristics of commodity export structures of selected countries in latin america the analysis is conducted both for the export structure of traditionally exported commodities and for the non traditional agricultural commodities that are being promoted as part of recent export diversification efforts in these countries the results show that portfolio optimisation analysis can provide a valuable tool for the improvement of the risk return properties of various export structures

measuring the economic impact of monetary union the case of okinawa data from okinawa s monetary union with the united states in 1958 and with japan in 1972 are used to obtain a quantitative indication of how monetary union might affect the behavior of nominal and real shocks across two economies with monetary union the variance of the real exchange rate between two economies declines and their business cycle linkage becomes stronger a var analysis of output and price data for okinawa and japan further indicates that the contribution of asymmetric nominal shocks in business cycles becomes smaller monetary union thus seems to facilitate both nominal and real convergence

money output and income velocity this paper attempts to assess empirically the contribution of three structural shocks monetary institutional financial and fiscal and technological to output and velocity fluctuations in the national bank era and the post 1973 period to identify these shocks we impose only long run restrictions derived from a monetary growth model we find that higher money growth increases decreases velocity in the first second period depending crucially on the resulting changes in the transactions frequency credit enhancing financial or expansionary fiscal shocks have a permanent positive effect on velocity and a himp shaped effect on output whereas technological shocks cause velocity to decrease in the short run and output to move to a permanently higher level

evidence on the cross country transmission of monetary shocks the international transmission of monetary shocks between the us and canada is explored focusing on real variables such as consumption investment employment and the bilateral trade balance along with measures of us and canadian money the empirical analysis examines the impact of a monetary shock in one country on real activity in both countries the long run analysis provides evidence of cointegration among the variables and suggests that money plays an important role in the equilibrium relationships between the two countries variance decompositions and impulse response functions reveal interesting avenues of real transmission in the short run the short run analysis provides strong evidence that us monetary shocks affect real activity in both the usa and canada the analysis also indicates that canadian monetary disturbances affect canadian and us real activity and that many of these effects are similar in magnitude to the effects of us monetary shocks the importance of the nominal exchange rate

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

the transmission mechanism of business cycles among germany japan the uk and the usa the study analyses the interdependent relationships of business cycles among four major countries using la var methods the results are compared with results obtained using a standard var model for the total sample 1962 1995 it is found that the economies of individual countries move independently and that inter dependence is weak however causality from the usa to japan and from japan to germany can be observed it is also found that the ripple effect differs in the first 1962 1973 and second 1973 1995 sample periods a change in the international ripple effect on the business cycle may have occurred at the time of the first oil crisis these results are almost robust to the empirical techniques employed in the analysis

economic fluctuations in central and eastern europe the facts this article provides a detailed empirical analysis of quarterly frequency dynamics in macroeconomic aggregates in 12 countries of central and eastern europe cee it shows that business fluctuations in cee countries are in general more pronounced than in developed ones and are of similar size as in other emerging market economies private consumption is particularly volatile relative to major developed economies government spending is dominantly procyclical and net exports are strongly countercyclical the most frequent country outliers are the high inflation countries of bulgaria romania and russia especially in labour market price and exchange rate variables excluding these countries from the sample makes many of the observed patterns in cyclical dynamics more homogenous and broadly similar to ones established in developed economies

causes of capital flows in developing countries abstract this paper investigates the causes of capital flows in four developing countries mexico chile korea and malaysia using structural decomposition analysis it finds that the recent resurgence in capital movements is largely due to external reasons such as decreases in the world interest rate or recession in industrial countries domestic factors including country specific productivity shocks and demand shocks are relatively less important another interesting finding is that the fundamental causes of capital flows differ little across the countries under study these results suggest that developing countries need to pay attention to the financial arrangements associated with capital flows and to exchange rate policy as well as macroeconomic fundamentals to avoid financial crises in a world of increased capital mobility

commodity price instability and economic goal attainment in developing countries abstract this paper reviews the theoretical and empirical micro and macro foundations for the frequent claims that instabilities in international commodity markets have deleterious effects on goal attainment in primary commodity exporting developing countries this review leads to the conclusion that the available evidence does not support these claims the paper concludes with speculation on why such claims are so strong despite the lack of supporting evidence perhaps it is because of measurement problems and perhaps because of small but articulate groups with vested interests in overstating the problem

fiscal shocks and real exchange rate dynamics some evidence for latin america this paper analyses the effects of fiscal shocks using a two country macroeconomic model for output labour input government spending and relative prices which provides the orthogonality restrictions for obtaining the structural shocks dynamic simulation techniques are then applied in particular to shed light on the possible effects of fiscal imbalances on the real exchange rate in the case of six latin american countries using quarterly data over the period 1980 2006 we find that in a majority of cases fiscal shocks are the main driving force of real exchange rate fluctuations

an equilibrium theory of nominal and real exchange rate comovement abstract this study develops a quantitative equilibrium theory to offer an explanation of one of the most puzzling aspects of empirical exchange rate behavior the high degree of nominal and real exchange rate comovement technology shocks coupled with the accomodative response of monetary policy to output fluctuations are primarily responsible for the covariation between nominal and real exchange rates shocks to the marginal efficiency of investment also play an important role

do country specific shocks matter evidence from australia and high income countries a stylized fact of global upward trend in domestic world output ratio for major small open economies is recognized in comparison with australia s dichotomous experience with the ratio this fact is used to shed light on the importance of country specific shocks for small open economies using a simple real business cycle model while it has been previously found that country specific shocks are more significant source of business cycle fluctuations than worldwide shocks for australia before the 1990s this article suggests that the country specific shocks may have become an important driver of output growth only in the early 1990s for australia

what does export diversification do for growth an econometric analysis it is frequently suggested that export diversification contributes to an acceleration of growth in developing countries horizontal export diversification into completely new export sectors may generate positive externalities on the rest of the economy as export oriented sectors gain from dynamic learning activities due to contacts with foreign purchasers and exposure to international competition vertical diversification out of primary into manufactured exports is also associated with growth since primary export sectors generally do not exhibit strong spillovers yet there have been remarkably few empirical investigations into the link between export diversification and growth this paper attempts to examine the hypothesis that export diversification is linked to economic growth via externalities of learning by doing and learning by exporting fostered by competition in world markets the diversification led growth hypothesis is tested by estimating an augmented cobb douglas production function on the bas

understanding global liquidity abstract we explore the concept of global liquidity based on a factor model estimated using a large set of financial and macroeconomic variables from 24 advanced and emerging market economies we measure global liquidity conditions based on the common global factors in the dynamics of liquidity indicators by imposing theoretically motivated sign restrictions on factor loadings we achieve a structural identification of the factors the results suggest that global liquidity conditions are largely driven by three common factors and can therefore not be summarised by a single indicator these three factors can be identified as global monetary policy global credit supply and global credit demand

business cycle comovement in the g 7 common shocks or common transmission mechanisms what are the sources of macroeconomic comovement among g 7 countries two main candidate explanations may be singled out common shocks and common transmission mechanisms in the article it is shown that they are complementary rather than alternative explanations by means of a large scale factor vector autoregressive fvar model allowing for full economic and statistical identification of all global and idiosyncratic shocks it is found that both common disturbances and common transmission mechanisms of global and country specific shocks account for business cycle comovement in the g 7 countries moreover spillover effects of foreign idiosyncratic disturbances seem to be a less important factor than the common transmission of global or domestic shocks in the determination of international macro economic comovements

international transmission of anticipated inflation under alternative exchange rate regimes this paper studies the international transmission of anticipated inflation a two country two good two currency cash in advance model is used to examine analytically and numerically the consequences of changes in a country s inflation rate domestic monetary policy influences real activity at home through an inflation tax channel these real effects are transmitted to the foreign country via fluctuations in the real exchange rate under a flexible nominal exchange rate inflation is a beggar thy neighbor policy under a fixed nominal exchange rate each country suffers a welfare loss when one country inflates the quantitative results are fairly insensitive to variations in the cash credit mix used to finance investment expenditures 2001 elsevier science ltd all rights reserved

capital mobility and international sharing of cyclical risk this paper investigates whether the international globalization of financial markets allows for significant cross country risk sharing at the business cycle frequency we find that cross country risk sharing is still limited and this is unlikely to be the result of financial frictions that limit state contingent contracts part of the limited international risk sharing could be the consequence of frictions that de facto reduce the short term mobility of financial capital but even with these frictions we find significant divergence between model predictions and the data

international good market segmentation and financial innovation abstract while international capital flows are now well liberalized markets for goods remain segmented to investigate how financial innovation may relieve the effects of this segmentation on risk sharing we examine a series of two country economies with internationally segmented good markets distinguished by the available financial securities sufficient conditions for efficiency include complete international financial markets together with liberalized international financial flows under these conditions heterogeneous agents from the same country may use securities as a substitute for the international shipment of goods this allows them to partially circumvent the segmentation allowing for efficient risk sharing

commodity concentration and export earnings instability a shift from cross section to time series analysis conventionally commodity concentration has been regarded as a major factor contributing to the short term instability in earnings experienced by developing countries the repeated and unexpected lack of correspondence between the conventional view and results of empirical studies has generated attempts to identify the limitations of the customary analytical framework this paper attempts to derive a more satisfactory alternative framework application of this alternative approach to export data for a sample of developing countries produces results which in contrast to the evidence of previous studies indicate the widespread existence of a statistically significant positive relationship between concentration and export instability

product diversification and stability of employment and sales first evidence from german manufacturing firms we use a unique rich newly built data set for german manufacturing enterprises to investigate the relationship between product diversification and the stability of sales and employment we find that contrary to portfolio theoretic considerations more diversified firms exhibit a higher variability of sales and employment however the effects are negligibly small from an economics point of view

unintended consequences energy r d in a deregulated energy market abstract many advanced industrialized nations are substantially reducing their national public and private investments in energy research and development r d driven in part by changes occurring as a result of the deregulation of these nations energy sectors in particular funding for strategic energy r d aimed at developing future energy supply options eg fusion fission clean fossil energy renewable energy has been decreased substantially in both the public and private sectors in many of these nations these trends are now starting to be seen in the united states as it moves towards the deregulation of the nation s utilities the magnitude of the reductions in support for energy r d in the public and private sectors and the shift towards decidedly shorter term r d has profound implications for nations approaching deregulation though utility customers may be short term winners from the deregulation of utilities by paying less for energy a national failure to invest in energy r d is very likely to have long term negative impacts on national energy sectors the economies and environmental wellbeing

income effects on the trade balance this paper investigates the income effects on the trade balance with particular attention to the distinction between permanent and transitory disturbances for the united states japan germany and the united kingdom in all four countries movements in the trade balance have mostly been associated with transitory changes in income the latter also are negatively associated with the trade balance in marked contrast permanent changes in income have little to do with the trade balance these results are examined in light of intertemporal models and real business cycle models copyright 1996 by mit press

on the sources of business cycles in the g 7 abstract this paper examines sources of cyclical movements in output inflation and the term structure of interest rates in the g 7 it employs a novel identification approach which uses the sign of the theoretical cross correlation function in response to shocks to catalog orthogonal disturbances we find that demand shocks are the dominant source of output and inflation fluctuations in several of the g 7 countries the proportion of term structure variability explained by different structural sources does not depend on the horizon apart from the us and canada structural shocks are nearly uncorrelated across countries

do the ecb and the fed really need to cooperate optimal monetary policy in a two country world abstract a two country model with monopolistic competition and price stickiness is employed to investigate the implications for macroeconomic stability and the welfare properties of three international policy arrangements a cooperative b non cooperative and c monetary union i characterize the conditions under which there is scope for policy cooperation and quantify the costs of non cooperation and monetary union the non cooperative equilibrium may be suboptimal because of terms of trade spillover effects while monetary union may be suboptimal because of the sluggishness of relative prices both the costs of policy competition and of a monetary union are sensitive to the values assumed for the intertemporal and international demand elasticity and the degree of openness of the economy independently of the calibration scenario adopted the ecb has little to gain by coordinating with the fed

income effects on the trade balance in small open economies the objective is to determine the causes of the countercyclicality of the trade balance in five small open economies namely austria france italy spain and switzerland in order to investigate the role of permanent and temporary changes in income in the determination of the trade balance blanchard quah variance decomposition procedure is applied the results of analysis support the conclusion that transitory income shocks are major reasons for the change in the trade balance and that negative correlation between the trade balance and income is primarily due to transitory shocks thus these results are more consistent with intertemporal models with the dichotomous view in which the aggregate demand shocks are responsible for cyclical variations in the trade balance and income and aggregate supply is responsible for the long run growth of the economy

financial integration and international business cycle co movement international business cycle transmission through integrated financial markets occurs through wealth and balance sheet effects balance sheet effects lead to business cycle convergence but wealth effects lead to divergence this paper shows empirically that debt market integration has a positive effect on co movement implying that balance sheet effects are the main conduit for international transmission through integrated debt markets equity market integration has a negative effect implying that wealth effects are the main channel for international transmission through integrated equity markets distinguishing between wealth and balance sheet effects resolves some key discrepancies between empirical and theoretical findings in international macroeconomics

r d expenditures in liberalized electricity markets the case of turkey abstract current problems in the electricity sector require deployment of new technologies which are the outcome of research and development r d mostly on the other hand figures show that government energy r d expenditures have declined in many developed countries which mostly resulted from liberalization and restructuring moreover studies indicate that private energy r d expenditures have also been affected by the reform process as a result there are concerns about the declines in government and private energy r d expenditures which may hamper the deployment of sustainable energy technologies similar to other countries turkey has initiated electricity market reforms and it has been trying to establish a competitive electricity market since 2001 moreover it has increased its efforts to develop domestic low carbon energy technologies an assessment of the relation between r d expenditures and liberalization in the turkish power market shows that market reforms have created new demand and opportunities for equipment manufacturers and there have been an increase in r d expenditures performed by these companies on the other hand power companies have mostly refrained from performing r d expenditures due to their perception of r d expenditures as unnecessary as well as insufficient incentives lack of funds and uncertainties stemming from liberalized market framework

dynamic effects of financial intermediation over the business cycle ping wang this paper provides a empirical evidence that the financial intermediation disturbances can generate business cycles we examine three countries whose financial sectors are fully developed but quite distinct in their institutional and regulatory circumstances thus we can infer whether financial intermediation disturbances differ across dissimilar financial environments we find that the dynamic responses of output to financial intermediation shocks exhibit similar patterns in all cases studied however the various institutional and regulatory circumstances have generated different propagation mechanisms transmitting the financial disturbance to output in ways that lead the magnitudes of the responses to deviate across economies jel e32 e44 i introduction does the financial sector veil the real economy although some economists such as lucas 1988 argue that financial factors are over stressed there is a growing literature that theoretically cultivates the channels through which financial intermediation can influence economic fluctuations and long run growth rather than focus on the traditional monetary transmission mechanism this literature plants itself in the microfoundations of asymmetric information and contract theory the new financial intermediation literature stems from seminal works by diamond 1984 townsend 1983a 1983b and boyd and prescott 1986 that demonstrate that in the presence of private information and costly state verification it is optimal for borrowing and lending to be conducted under financial intermediary arrangements these ideas were then extended by williamson 1987 to show how disturbances in the financial intermediation sector can generate business cycle fluctuations essentially when investment projects become more risky or difficult to evaluate loan supply falls and business cycle movements emerge 1 moreover other financial intermediation impulses are likely to be important as well these include changes to the institutional framework or the regulatory environment and any other event that enhances or hinders the intermediaries capacity to allocate capital efficiently among competing alternative uses e g financial innovation yet despite the theoretical rhetoric on the importance of financial intermediation to output fluctuations the empirical relevance of financial intermediation remains an unsettled question this paper brings us one step closer to the solution by econometrically identifying structural financial intermediation disturbances and estimating their effect on output movements in three major industrialized countries germany the united kingdom and the united states we choose these three advanced economies not only because their financial sectors are fully developed but also because their distinct banking structures and regulatory environments are capable of generating and transmitting financial intermediation disturbances in different ways that is the depth of financial intermediation is relatively similar across countries therefore the cross country analysis allows us to focus on the ability of financial intermediation to generate short run cycles and to draw some suggestive insights regarding the role of regulatory and institutional factors across countries the existing empirical evidence linking financial factors to real economic activity has involved noticing statistical correlations between some financial variables and some real variables goldsmith 1969 using data from 1860 to 1963 showed that there is a positive relationship between economic development and the size of the financial sector kuznets 1971 in a cross section study of 57 developed and developing economies found that the share of banking insurance and real estate in gross domestic product rises as income increases mckinnon 1973 showed that the ratios of private credit to national income and a broad monetary aggregate to national income are positively related to per capita income

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

an empirical analysis on capital flows the case of korea and mexico this paper discusses causes of capital flows in korea and mexico both countries received substantial amounts of foreign capital in the late 1980s and early 1990s international capital helped these countries achieve a higher standard of living and faster economic growth however undesirable macroeconomic effects such as appreciation of real exchange rate and widening current account deficits usually accompany foreign capital inflows the vector autoregressive var method is applied to investigate the underlying shocks causing the capital inflows the main findings are that the u s business cycle and shocks to foreign interest rates account for more than 50 of capital inflows to both countries in the past two decades

international business cycles the authors estimate a dynamic two country model in which economic fluctuations are driven by a worldwide supply shock country specific supply shocks and relative fiscal money and preference shocks identification is achieved using only long run restrictions based on a theoretical model the main results are 1 supply shocks particularly country specific ones are very important in generating international business cycles and 2 although the post 1973 flexible exchange rate period has been inherently more volatile there are no differences in transmission properties of economic disturbances across exchange rate regimes for the endogenous variables they focus on copyright 1993 by american economic association

sources of international business fluctuations country specific shocks or worldwide shocks abstract this paper identifies sources of business fluctuations in a two country open economy model with the structural var method focusing on the relative importance of worldwide shocks and country specific shocks unlike previous studies which define country specific shocks as labor supply shocks this study explicitly identifies three kinds of permanent shocks worldwide shocks domestic country specific shocks and foreign country specific shocks with identifying restrictions derived from a theoretical model the main finding is that u s country specific shocks are the most important in explaining u s and foreign output fluctuations except in the short run

limited participation in international business cycle models a formal evaluation in this paper we study the role of limited asset market participation lamp for international business cycles we show that when limited participation is introduced into an otherwise standard model of international business cycles the performance of the model improves signi cantly especially in matching cross country correlations to perform formal evaluation of the models we develop a novel statistical procedure that adapts the test of vuong 1989 to dsge models and accounts for the possibility that models are misspeci ed based on this test we show that the improvements brought out by lamp are statistically signi cant leading a model with lamp to outperform a representative agent model furthermore when lamp is introduced a model with complete markets is found to do better than a model with no trade in nancial assets a well known favorite in the literature our results remain robust to the inclusion of investment speci c technical change

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

innovation processes in large technical systems market liberalization as a driver for radical change abstract electricity supply is a large technical system which exhibits strong path dependencies and high barriers for radical innovations recent market liberalization however has initiated a fundamental restructuring the paper analyzes how liberalization has altered innovation processes in the field of electricity supply we examine three radical innovations under monopoly conditions and contrast the findings with the results from a survey on the innovation behavior of electric utilities in liberalized markets we argue that the selection environment for innovations has changed in various respects in our sample new options open to innovation activities have emerged at the level of the firm and utility strategies turn out to be more heterogeneous this may be interpreted as an increase in the variety of search processes which may lead to a mid term decrease of path dependencies

international business cycles world region and country specific factors the paper investigates the common dynamic properties of business cycle fluctuations across countries regions and the world we employ a bayesian dynamic latent factor model to estimate common components in macroeconomic aggregates output consumption and investment in a 60 country sample covering seven regions of the world the results indicate that a common world factor is an important source of volatility for aggregates in most countries providing evidence for a world business cycle we find that region specific factors play only a minor role in explaining fluctuations in economic activity we also document similarities and differences across regions countries and aggregates jel f41 e32 c11 c32

trade and business cycle synchronization in oecd countries a re examination this paper re examines the relationship between trade intensity and business cycle synchronization for 21 oecd countries in the period 1970 2003 instead of using instrumental variables we estimate a multivariate model including variables capturing specialization and similarity of economic policies we confirm that trade intensity affects synchronization but the effect is much smaller than previously reported other factors like specialization and convergence in monetary and fiscal policies have a similar impact on business cycle synchronization as trade intensity the effect of trade on synchronization is not driven by outliers however the impact of trade on synchronization is not robust across deciles c 2007 elsevier b v all rights reserved

refinements on macroeconomic modeling the role of non separability and heterogeneous labor supply abstract this paper proposes a dynamic stochastic general equilibrium model characterized by heterogenous labor schedules and non separability between consumption and labor in the utility function the model successfully describes output consumption investment and interest rates after a monetary expansion the proposed formulation improves on standard models by using preferences favored by the data and by requiring investment adjustment costs and habit formation parameters more in line with the micro based evidence

institutional reform and technological practice the case of electricity this article proposes a framework for categorizing possible interrelations between technological and institutional change and applies this framework to the case of the restructuring of the electricity sector it is argued that there is a need for coherence between institutions and technological practice so as to safeguard the satisfactory functioning of electricity infrastructure the identification of possible incoherences between institutions and technological practice allows for a better understanding of the potential drivers for change and the evolutionary processes of which they may be part this article attempts to elaborate the nature of this co evolution in somewhat more detail using specific levels of analysis that are exemplified in a four level model in the case of the restructuring of the electricity sector the institutional framework has changed from a public utility oriented towards a market oriented system however the technological practice remained unchanged a system oriented approach that relies on centralized planning control and operation this discrepancy between institutions and technological practice leads to significant frictions in the functioning of the electricity sector but it also offers opportunities for innovation in order to make liberalization a success it might be necessary to stimulate certain technical developments i e distributed generation and intelligent networks

can government enforcement permanently alter fertility the case of china i introduction in developing countries per capita output growth objectives are often stymied by high birth rates 1 traditional values ignorance of birth control technology and labor intensive farming are all factors which contribute to high fertility rates for those reasons many developing countries experiencing high birth rates adopt population control policies while most programs combine educational efforts with some form of persuasion many also provide strong economic disincentives to high fertility 2 of particular interest from this vantage point is the experience of the people s republic of china which stands alone in its use of quotas on child bearing decisions 3 china s population control policy began with a massive campaign in 1953 reversing an earlier pro natalist stance however that campaign was curtailed by the political turmoil arising from the great leap forward and the cultural revolution population control programs resumed in 1970 with the issuance and enforcement of three reproductive norms late marriage longer spacing between births and fewer children in 1979 the authorities went even further allowing each household to have only one child interest in china s experience arises not only from the severity of the restrictions but also due to the government s ability to enforce them the feasibility of enforcing these restrictions is a result of the deep penetration of the communist party into most aspects of an individual s life including its control over housing employment and salaries 4 however despite the government s extensive involvement in birth planning those who study chinese demography have debated the extent to which government policies are responsible for the large fertility decline in the 1970s 5 this paper uses recent advances in economic theory and econometrics to quantitatively assess the main sources of fertility fluctuations in china specifically we employ a model with endogenous fertility choice which modifies the framework of razin and ben zion 1975 and barro and becker 1989 6 in contrast to other papers we focus on the relationship between government enforcement of population control policies and fertility outcomes we also allow the fertility rate to be affected by 1 household preferences including alterations in taste as well as in education health care and the changing role of women and 2 production technology which mostly captures changes in agricultural output or income we perform simple comparative static analysis to examine long cycles in fertility and output and characterize the transitional dynamics which govern short cycles easterlin 1968 and lee and loschky 1987 provide nice discussions of long fertility cycles the long run steady state predictions will be used to identify the empirical structural vector autoregression var system as well as interpret the underlying structural disturbances additionally the transitional dynamics results can be compared to the estimated dynamic structure finally we employ a structural var as in blanchard and quah 1989 and ahmed ickes wang and yoo 1993 to econometrically disentangle the relative contributions of policy and economic development factors to changes in fertility growth the structural disturbances include a change in the government s enforcement power a technological advance in agricultural production and a preference shift toward a higher fertility rate all of which are capable of generating both short and long cycles in fertility and output we find that government enforcement power has a significant negative effect on fertility accounting for about one third of the variance of the forecast error for fertility growth after the first year an expansion in agricultural output on the other hand yields a short run positive impact on fertility growth and is responsible for almost one fifth of fertility growth variations furthermore while theoretically all shocks have the potential to generate long cycles only preference shifts have statistically significant long run effects

dynamics of the trade balance and the terms of trade the j curve the authors provide a theoretical interpretation of two features of international data the countercyclical movements in net exports and the tendency for the trade balance to be negatively correlated with current and future movements in terms of trade but positively correlated with past movements they document the same properties in a two country stochastic growth model in which trade fluctuations reflect in large part the dynamics of capital formation the authors find that their general equilibrium perspective is essential the relation between the trade balance and the terms of trade depends critically on the source of fluctuations copyright 1994 by american economic association

does asymmetry of international shocks matter for the u s business cycle this article proposes and investigates the asymmetry hypothesis which predicts that an international asymmetric shock tends to have a stronger and longer effect on the u s business cycle than a symmetric shock the hypothesis finds empirical support in the impulse responses of u s output and inflation to symmetric and asymmetric shocks those responses are estimated in a four variable structural vector autoregression the hypothesis also finds support in stylized facts the longest u s expansions have tended to occur when the rest of the world was growing below potential jel e3 e5 e4 i introduction economic expansions in the united states since world war ii have tended to end with the same pattern as the economy approaches capacity wage and price inflation begins to rise the federal reserve then tightens monetary policy to dampen inflationary pressures thereby pushing the economy into a recession 1 the expansion that ended in march 2001 however appeared to deviate from this pattern it was associated with little inflationary build up and consequently the federal reserve did not begin a string of uninterrupted tightening until late june 1999 when consumer price index cpi inflation was running only slightly above the 2 rate by comparison consumer prices were rising at 6 2 at the end of the 1960s boom and over 5 at the end of the 1980s boom clearly the monetary tightening of 1999 was enacted more in reaction to the threat of inflation in light of the tight labor market than to actual high inflation what made the 1990s expansion different a number of explanations have been offered for the longevity of the latest expansion that the credit markets have played an important role in sustaining the current expansion 2 that greater fiscal discipline and enhanced central bank credibility have helped tame inflation expectations and sustain the boom that the rise in the services component of gross domestic product gdp relative to manufacturing and more efficient inventory management have contributed to rendering the economy less susceptible to cyclical swings that the increase in productivity growth caused by digital technology has helped meet increases in demand and labor shortages without driving up inflation or that globalization per se has helped prolong the expansion this article considers another factor that is likely to have helped increase the longevity of the 1990s expansion we call this factor the asymmetry hypothesis the hypothesis maintains that in a flexible exchange rate regime an asymmetric that is country specific shock will have a stronger and longer effect on output than will a shock that also hits the rest of the world the hypothesis makes two assumptions that the united states is sufficiently integrated with the rest of the world or globalized and that the federal reserve is forward looking and at least partly effective in combating inflation and recessions under those assumptions an expansion caused by a symmetric positive shock is accompanied by stronger inflationary pressures than an expansion caused by an equal sized asymmetric shock prompting quicker and stronger monetary tightening consequently an expansion caused by a symmetric shock ends earlier than one caused by an asymmetric shock symmetrically a contraction caused by a symmetric negative shock is potentially more devastating for the economy than one caused by an equal sized asymmetric shock prompting quicker and stronger monetary easing thus a contraction caused by a symmetric shock ends earlier than a contraction caused by an asymmetric shock this article builds a two country open economy model to illustrate why the hypothesis makes sense in an age of globalization and a forward looking monetary regime it then estimates a structural vector autoregression svar system using both long run and short run restrictions to investigate whether the hypothesis can stand the scrutiny of empirical study

portfolio models and planning for export diversification malawi tanzania and zimbabwe evidence is presented regarding strengths and limitations of portfolio approaches as applied to diversifying export earnings an empirical application using data from malawi tanzania and zimbabwe is used to demonstrate these strengths and limitations modifications of the typical portfolio approach to export diversification are presented these modifications help make the approach more plausible for use in developing countries the modified approach is shown to provide guidance to policymakers who seek simultaneously to increase export earnings and reduce their instability

are correlations of stock returns justified by subsequent changes in national outputs abstract in an integrated world capital market the same pricing kernel is applicable to all securities we apply this idea to the stock returns of different countries we investigate the underlying determinants of cross country stock return correlations first we determine for a given measured degree of commonality of country outputs what should be the degree of correlation of national stock returns we propose a framework that contains a statistical model for output and an intertemporal financial market model for stock returns we then attempt to match the correlations generated by the model with measured correlations our results show that under the hypothesis of market segmentation the model correlations are much smaller than observed correlations however assuming world markets are integrated our model correlations can be matched with observed correlations

international trade and the business cycle this paper develops a new empirical framework for analysing the dynamics of the trade balance in response to different types of macroeconomic shocks the model provides a synthetic perspective on the conditional correlations between the business cycle and the trade balance that are generated by different shocks and attempts to reconcile these results with unconditional correlations found in the data the results suggest that in the post bretton woods period nominal shocks have been an important determinant of the forecast error variance for fluctuations in the trade balance in g 7 countries the world economy has become increasingly integrated in recent years spurred by rapid expansions in trade and financial flows across national borders the rising share of international trade in world output suggests that trade could potentially have a greater influence on business cycle fluctuations both within and across countries hence understanding the factors driving fluctuations in international trade is important from a number of different perspectives including macroeconomic forecasting as well as for short run domestic policy considerations and international policy coordination the existing empirical literature on international aspects of business cycle fluctuations has followed a number of different approaches one strand of literature uses error component models to identify the sources of business cycle fluctuations and to assess the importance of common international shocks relative to country specific or industry specific shocks see stockman 1988 glick and rogoff 1995 another approach has been to document the role of international trade in the transmission of business cycles across countries as in

how well can the new open economy macroeconomics explain the exchange rate and current account abstract this paper advances the new open economy macroeconomic literature in an empirical direction estimating and testing a two country model fit to u s and g7 data the model performs moderately well for the exchange rate and current account results offer guidance for future theoretical work parameter estimates lend support to the assumption of local currency pricing estimates are found for key parameters commonly calibrated in the theoretical literature such as the elasticity of substitution between home and foreign composite goods and the response of a country s risk premium to the net foreign asset position results also indicate that deviations from interest rate parity are not closely related to monetary policy shocks as recently hypothesized but that these deviations are strongly related to shifts in the current account

mode locking and international business cycle transmission abstract we investigate international business cycle synchronization business cycles in many countries have a tendency to synchronize with one another in what appears to be a world business cycle yet researchers find that trade and capital linkages are not strong enough for one country to drive business cycles in another country how is this world business cycle formed this study suggests that the world business cycle results from a mode locking phenomenon a nonlinear process by which weak coupling between oscillating systems tends to synchronize oscillations in the systems simulations and econometric analyses are performed to attempt to verify this hypothesis

reserve accumulation and financial crises from individual protection to systemic risk abstract this paper provides a new perspective on the relationship between countries international reserve holdings and financial crises while the local view holds that reserves may prevent domestic crises it overlooks that the accumulation of reserves relaxes the financing constraint of the reserve currency country and may cause a financial crisis in the centre which is transmitted globally according to this global view reserve accumulation might destabilize the international financial system since the crisis affects all countries alike the accumulation of reserves imposes a negative externality on non accumulating countries we integrate this idea in a theoretical model of the optimal amount of reserves and illustrate the gap between local and global optimality the consideration of systemic risk lowers the demand for reserves moreover if a supranational authority determines the optimal level of reserves it internalizes the negative externality and accumulates fewer reserves a macroprudential tax on reserve hoardings might implement the socially optimal solution our calibration analysis shows that these considerations are economically significant they lower the optimal amount of reserves in the benchmark case by 45

determinants of business cycle comovement a robust analysis abstract this paper investigates the determinants of business cycle comovement between countries our dataset includes over 100 countries both developed and developing we search for variables that are robust in explaining comovement using the approach of leamer amer econom rev 73 1983 31 variables considered are i bilateral trade between countries ii total trade in each country iii sectoral structure iv similarity in export and import baskets v factor endowments and vi gravity variables we find that bilateral trade is robust however two variables that the literature has argued are important for business cycles industrial structure and currency unions are found not to be robust

energy market reforms in turkey and their impact on innovation and r d expenditures abstract energy sector is encountering serious problems which can be solved by technological innovations and increasing r d expenditures on the other hand energy market reforms notably the establishment of competitive electricity and natural gas markets have resulted in a decrease of government energy r d expenditures in most countries furthermore there are rising concerns that private energy r d expenditures are also declining as a result of energy market reforms and companies are choosing customer oriented innovations which may jeopardize the deployment of sustainable and renewable energy technologies turkey initiated energy market reforms in 2001 and has been trying to establish competitive electricity and natural gas markets since then a survey of electricity and natural gas transmission and distribution companies in turkey showed that nearly all of these companies have refrained r d expenditures and have made organizational innovations mostly moreover government energy r d expenditures are very low compared to developed countries and enterprises are still trying to adapt to new market conditions nonetheless energy market reforms may have positive effects on r d expenditures and innovations as turkey completes privatization of distribution companies eliminates uncertainties in electricity and natural gas markets and take measures to increase collaboration among enterprises universities and government agencies

the transmission of disturbances under alternative exchange rate regimes with optimal indexing the paper develops a general stochastic macroeconomic model that can be used to study the international transmission of disturbances under four alternative exchange rate systems uniform flexible exchange rates uniform fixed exchange rates and two versions of two tier exchange rates the analysis makes two general points first one cannot assume stability of structure when assessing the consequences of alternative exchange rate regimes for example the slope of the aggregate supply curve and the rationally formed expectations in the asset markets can respond dramatically to the government s choice of exchange rate regime second exchange rate regimes that provide full insulation from foreign disturbances may nevertheless be inferior to other regimes in terms of their ability to maximize social welfare

stochastic trends and economic fluctuations in a large open economy abstract this study examines the role of stochastic trends in real exchange rates and foreign output in explaining economic fluctuations in the united states while many of the results are consistent with recent closed economy studies the evidence shows that external shocks have significant short run effects on economic fluctuations even in a large country a real appreciation of the dollar leads to permanent decreases in net exports and temporary decreases in output permanent shocks to real exchange rates have surprisingly large effects on output over the course of the normal business cycle

a new look at the benefits of diversification lessons from central america recent trends of export diversification in central america may lower foreign exchange earnings instability there four countries costa rica el salvador honduras and guatemala are analysed across a twenty year period the paper uses united nations commodity trade statistics to explain why costa rica and honduras have enjoyed greater earnings stability in recent years despite the fact that honduras has not greatly diversified its export products and markets despite the growth of new agricultural and manufacturing goods traditional primary products still dominate the countries export portfolios specific products within each of the four broad product category groups contribute to the varied country outcomes summary statistics from the united nations panel data suggest newer agricultural exports have not stabilized guatemalan and salvadoran export earnings while honduras has enjoyed relatively stable banana export revenues and costa rica has benefited from the smooth flow of microelectronic product

currency of denomination and the measurement of export instability the widespread and unexpected absence of statistically significant relationships in analyses of the causes and consequences of export instability has generated attempts to refine measurement of variable sets recently it has been suggested that country rankings are sensitive to the choice of currency numeraire this article investigates the significance of the choice of numeraire for a sample of 66 developing countries the results suggest that the conventional approach of denominating export earnings in terms of us dollars is not seriously deficient and that the selection of an appropriate form of trend correction remains an important consideration

global implications of national unconventional policies abstract financial integration in the markets for banks assets and liabilities makes balance sheet constraints highly correlated across countries resulting in a high degree of financial and macroeconomic interdependence likewise under financial integration unconventional policies aimed at stabilizing domestic financial and credit conditions could entail large international spillovers therefore stabilization by one country will also benefit other countries reducing incentives to implement credit policies in a classic free riding problem especially when these policies entail domestic costs we show that this outcome can emerge in an open economy model featuring financial intermediaries that face endogenously determined balance sheet constraints

a new look at the effects of export instability on investment and growth abstract this paper is concerned with the effects of export instability on investment and growth it is shown that past cross sectional empirical studies on the effects of export instability either in prices or in value terms used an incorrect measure of instability that does not properly take account of the share of exports in gdp using a new instability index and a broad set of conditioning variables it is shown that export instability was positively associated with investment but negatively associated with growth in a large sample of countries during the period from the early 1970s to the mid 1980s

export instability an alternative analysis of causes numerous studies into the causes of the export instability experienced by developing countries have failed to establish any significant relationships this paper suggests that the widely used technique of cross country regression analysis is inappropriate and that the typical explanatory variable set is inadequately specified accordingly analysis is shifted to a time series basis at the level of individual countries and explanatory variables are developed which correspond more closely to the supply and demand determinants of instability applying this alternative model to data for a sample of developing countries produces results which suggest that this approach has considerable explanatory power

predicting inflation does the quantity theory help i introduction inflation forecasting has played a key role in recent u s monetary policy and this has led to a renewed search for variables that serve as good indicators of future inflation one frequently used indicator based on the phillips curve is the unemployment rate or a similar measure of the output gap as in gerlach and svensson 2003 clark and mccracken 2003 mankiw 2001 and gali and gertler 1999 the phillips curve is believed by many to be the preferred tool for forecasting inflation see e g mankiw 2001 stock and watson 1999a blinder 1997 though as argued by sargent 1999 its use in formulating monetary policy is not without controversy another approach based on the quantity theory of money uses monetary aggregates to predict inflation despite the strong theoretical motivation for this approach though there is little evidence that measures of the nominal money supply are useful for predicting inflation relative to a conventional unemployment rate phillips curve model see stock and watson 1999a for a detailed analysis of the forecast performance of popular inflation indicators stock and watson s results indicate that even simple univariate time series models generally forecast about as well as models that include measures of the money supply so that it is hard to make the case that nominal money supply data have any predictive content for inflation 1 this article evaluates inflation forecasts made by models that allow for prices money and output to be cointegrated and in the process reexamines the question of whether monetary aggregates have marginal predictive content for inflation our work is motivated in part by economic theory as the presence of a cointegrating relationship among the series we look at corresponds to an implicit assumption that prices the money supply and output hang together in the long run an implicit feature of most analyses based on the quantity theory from a statistical point of view a system with cointegrated regressors does not have a finite order vector autoregressive var representation so that a var in differences will be misspecified and may not forecast well regardless of the relevance of the included variables our analysis is therefore focused on the questions are there gains in terms of forecast accuracy from imposing the restriction that prices money and output are cointegrated does it matter whether cointegrating restrictions are imposed a priori based on economic theory or can they be estimated and do models imposing cointegration among prices money and output forecast inflation as well as the phillips curve and other alternative models the econometric framework that we employ is similar to that of stock and watson 1999a but differs from theirs in two ways first stock and watson 1999a consider one year horizon inflation forecasts whereas we consider forecast horizons of up to five years this is potentially important in our context as we include versions of the quantity theory of money in our analysis a theory that arguably may not yield substantive gains to forecasting in the short run additionally future inflation at many horizons is in general of interest to policy makers even if the weight attached to inflation at different horizons is a matter of individual preference so that long run predictions are only unuseful if and when they fail to have marginal predictive content for inflation 2 a second difference between our work and that of stock and watson 1999a is that some of our models differ from theirs including those that impose quantity theory based cointegrating restrictions for example in these types of models we 1 impose a cointegration restriction derived from the assumption of stationary velocity and 2 estimate cointegrating restrictions we also examine a fairly broad variety of linear models including simple autoregressive ar models in levels and differences conventional unemployment rate phillips curve models and var models in levels and differences with money prices and output

estimating the liquidity effect in post reform chile do inflationary expectations matter abstract in this paper we estimate the dynamic effects of domestic money supply shocks in chile over its post reform era we analyze chile since inflationary expectations could be very sensitive to changes in the money supply given past inflationary experience in the context of a var model containing both chilean and us variables we identify money supply shocks using long run monetary neutrality and block exogeneity restrictions our findings suggest that in chile over the period from 1977 to 1998 unexpected domestic money supply shocks have had a positive impact on interest rates in the short run and a negative impact on real money balances this differs markedly from the estimated responses of the us the findings are consistent with the notion that at least in chile inflationary expectations are very sensitive to news about the nominal money supply possibly due to high inflationary uncertainty and the lack of credibility of monetary reforms our results are generally robust to alternative model specification and identifying restrictions

changes in the effects of monetary policy on disaggregate price dynamics abstract based on a time varying factor augmented vector autoregression we demonstrate that the propagation mechanism of monetary policy disturbances differs across disaggregate components of personal consumption expenditures while many disaggregate prices rise temporarily in response to a monetary tightening in the early part of the sample there is no evidence of a price puzzle at the aggregate level the share of disaggregate prices that exhibit the price puzzle diminishes from the early 1980s onwards there also is evidence of a substantial decline in the dispersion of disaggregate price responses over time this gradual decrease in cross sectional heterogeneity of disaggregate price responses is associated with a dampening effect on aggregate real economic activity and a stronger effect on the aggregate price level we illustrate by means of a multi sector sticky price model augmented by a cost channel how key structural parameters would have had to change to match this evolution of sectoral price dynamics

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

exchange rate volatility and the time varying effects of aggregate shocks abstract this paper investigates the dynamics of the real exchange rate and relative output among the us and five of its top six trading partners since the collapse of bretton woods it employs long run restrictions to identify the usual suspect macroeconomic shocks and their relative importance for exchange rate fluctuations an improvement of the econometric application is that it allows for the contribution of each shock to the real exchange rate and relative output to vary over time while the volatility of us output both total and relative to that of the uk or canada is estimated to have substantially reduced since the mid 1980s consistent with the great moderation findings of many others the volatility of real exchange rates has experienced a gradual and continuous increase over the same period monetary shocks account for only a small fraction of these dynamics although they do track well the increase in volatility of us output during the great inflation period it is supply type shocks that seem to be more important for the relative output volatility reductions of the mid 1980s conversely demand shocks seem to account for the largest portion of the volatility increases in the real exchange rate perhaps unsurprisingly both volatilities increase during the 2007 financial crisis and the ensuing 2008 2009 great recession periods associated with higher economic uncertainty

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

putting the new open economy macroeconomics to a test abstract this paper explores one way to extend the new open economy macroeconomics in an empirical direction adapting maximum likelihood procedures it estimates and tests an intertemporal small open economy model with monetary shocks and nominal rigidities results offer mixed support for a benchmark model where prices are assumed to be sticky in the currency of the buyer price stickiness seems to be an important element as overall results are poorer for versions of the model in which prices either are flexible or are sticky in the currency of the producer the benchmark model does a better job explaining some variables than others in particular it does a poor job explaining exchange rate movements
