financial markets and growth the last five years have witnessed a resurgence of interest in the relationship between financial intermediation and economic growth this issue had been extensively studied nearly two decades earlier by goldsmith 1969 mckinnon 1973 shaw 1973 and others who produced considerable evidence that financial development correlates with growth but their work though insightful lacked analytical foundations in traditional growth theory financial intermediation could be related to the level of the capital stock per worker or to the level of productivity but not to their respective growth rates the latter were ascribed to exogenous technical progress the recent revival of interest in the link between financial development and growth stems mainly from the insights and techniques of endogenous growth models which have shown that there can be self sustaining growth without exogenous technical progress and that the growth rate can be related to preferences technology income distribution and institutional arrangements this provides the theoretical underpinning that early contributors lacked tinancial intermediation can be shown to have not only level effects but also growth effects the resulting models have offered important insights into the effect of financial development on growth and vice versa they have also provided new impetus to empirical research on these issues this paper reviews the ground covered so far on the theoretical and empirical front and points to some still unresolved issues

explaining business cycles in small open economies abstract this paper analyzes the role of world price shocks fluctuations in the prices of capital intermediate and primary goods and in the world real interest rate in the generation and propagation of business cycles in small open developing countries i construct a stochastic dynamic multi sector small open economy model the model is a variant of the specific factors model and reflects the major structural characteristics of developing economies i utilize variance decomposition methods to quantitatively evaluate the impact of world price shocks the results indicate that world price shocks account for a significant fraction of business cycle variability in developing countries

similarities and convergence in g 7 cycles this paper examines the properties of g 7 cycles using a multicountry bayesian panel var model with time variations unit specific dynamics and cross country interdependences we demonstrate the presence of a significant world cycle and show that country specific indicators play a much smaller role we detect di erences across business cycle phases but apart from an increase in synchronicity in the late 1990s find little evidence of major structural changes we also find no evidence of the existence of an euro area specific cycle or of its emergence in the 1990s

the real effects of financial integration abstract this paper shows how correlations in gdp fluctuations rise with financial integration finance serves to increase international correlations in both consumption and gdp fluctuations which explains the persistent gap between the two in the data a quantity puzzle the positive association between financial integration and gdp correlation constitutes a puzzle as theory suggests a negative relation if anything nevertheless it prevails in the data even after the effects of finance on trade and specialization are accounted for

inflation financial markets and long run real activity abstract empirical evidence suggests that real activity the volume of bank lending activity and the volume of trading in equity markets are strongly positively correlated at the same time inflation and financial market activity are strongly negatively correlated in the long run as are inflation and the real rate of return on equity inflation and real activity are also negatively correlated in the long run particularly for economies with relatively high rates of inflation we present a monetary growth model in which banks and secondary capital markets play a crucial allocative function we show that at least under certain configurations of parameters the predictions of the model are consistent with these and several other observations about inflation finance and long run real activity

a policy response to the e commerce revolution the case of betting taxation in the uk several environmental changes in the 1990s including the introduction of a national lottery the rise of internet gambling and the reduction of trade barriers within the eu induced the uk government to initiate a large scale review of betting duty as a result of this review the government recently announced a significant reduction in betting taxes they also decided to replace the current general betting duty gbd levied as a proportion of betting stakes with a gross profits tax gpt based on the net revenue of bookmakers we examine the economic rationale behind these decisions and demonstrate how these tax changes have broad implications regarding optimal levels of taxation for other sources of government revenue

trying to explain home bias in equities and consumption investors hold a substantially larger proportion of their wealth portfolios in domestic assets than standard portfolio theory would suggest a phenomenon called equity home bias in the absence of this bias investors would optimally diversify domestic output risk using foreign equities therefore consumption growth rates would tend to co move across countries even when output growth rates do not empirically however consumption growth rates tend to have a lower correlation across countries than do output growth rates a phenomenon i call consumption home bias in this paper i discuss these two biases and their potential relationship as suggested by the literature

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

inflation and asset returns sustained inflation is detrimental to long run growth and the financial system a recent theoretical literature suggests that high inflation implies low real returns on assets these low returns exacerbate informational frictions interfering with the functioning of financial markets and the allocation of investment we investigate the plausibility of an inverse relationship between inflation and real returns inflation and nominal equity returns are negatively correlated or uncorrelated for all low to moderate inflation economies examined safe nominal rates of return and inflation are only weakly positively correlated however for high inflation economies inflation and nominal returns are strongly positively correlated

the role of financial sector competition for monetary policy in this paper we examine the impact of competition in the banking industry on financial market activity in particular we explore this issue in a setting where banks simultaneously insure individuals against liquidity risk and offer loans to promote intertemporal consumption smoothing in addition spatial separation and private information generate a transactions role for money interestingly we demonstrate that the industrial organization of the financial system bears significant implications for the effects of monetary policy under perfect competition higher rates of money growth lead to lower interest rates and a higher volume of lending activity in contrast in a monopoly banking sector money growth restricts the availability of funds and raises the cost of borrowing

bank commercial loan markets and the role of market structure evidence from surveys of commercial lending abstract this paper seeks to test two tenets that underlie the current practice of antitrust analysis in banking the first is the view that bank commercial loan markets are local in nature and the second is the view that banks in more concentrated markets are more likely to engage in some form of noncompetitive behavior tests of both of these tenets are conducted using an extensive set of loan specific survey information not previously employed to address these issues results consistent with the existence of local banking markets and the dominance of competitive differences as an explanation for observed differences in loan rates are found

market structure and the nature of price rigidity evidence from the market for consumer deposits panel data on consumer bank deposit interest rates reveal asymmetric impacts of market concentration on the dynamic adjustment of prices to shocks banks in concentrated markets are slower to raise interest rates on deposits in response to rising market interest rates but are faster to reduce them in response to declining market interest rates thus banks with market power skim off surplus on movements in both directions since deposit interest rates are inversely related to the price charged by banks for deposits the results suggest that downward price rigidity and upward price flexibility are a consequence of market concentration

the emergence of regional business cycle in africa a reality or myth a bayesian dynamic factor model analysis this paper examines the evolution and the underlying forces of the business cycle co movements among seven african a 7 countries over the period 1970 2016 these countries accounted for over 60 of regional gdp have abundant natural resources access to the global capital market and widely viewed as potential drivers of regional or african business cycle we model the national business cycle using real output consumption and investment we employ a dynamic factor model to decompose fluctuations in these macro variables into a regional country specific and idiosyncratic components using bayesian methods we also analyse the relative importance of some notable drivers of business cycle fluctuations found in the literature we find that the idiosyncratic component is dominating cyclical fluctuations in the a 7 countries while country specific and regional factors play a negligible role suggesting the inexistence of a common regional cycle despite deepening intra african trade among the driving variables the terms of trade shocks exert greater influence on the a 7 business cycle while exchange rate movements and changes in money supply explain sizeable fluctuations in consumption and investment in most of the a 7 countries shocks associated with changes in relative domestic oil prices monetary and fiscal policies cause large output fluctuations

market structure and the pass through of the federal funds rate abstract we study the effect of local market bank concentration on business loan originations and on the pass through of the federal funds rate to business loan originations economic theory on the relationship between concentration and the pass through of input prices to quantity or price is ambiguous we find that more concentrated markets have lower business loan originations and experience smaller changes in business loan originations in response to changes in the federal funds rate our results support the idea that market concentration dampens quantity reactions to input price changes

global business cycles convergence or decoupling we analyze the evolution of the degree of global cyclical interdependence over the period 1960 2008 using a dynamic factor model we decompose macroeconomic fluctuations in output consumption and investment into a global factor factors specific to country groups and country specific factors we find that during 1985 2008 there is some convergence of business cycle fluctuations among industrial economies and among emerging market economies surprisingly there is a concomitant decline in the relative importance of the global factor we conclude that there is evidence of business cycle convergence within each of these two groups of countries but divergence or decoupling between them

the decoupling of emerging economies theoretical and empirical puzzle with the growing importance of the emerging economies ees in the international scene a lively debate has begun on whether the national economic cycles are converging or the cycles of ees and advanced economies aes are becoming disconnected the so called hypothesis of decoupling of ees from the aes given the important practical implications that decoupling could have for example on the definition of national and international economic policies and on business strategies aimed at investment diversification and risk management the question kindles not only the interest of academics but also policymakers and practitioners are very interested in the issue the decoupling question has been long debated in different circles and from different points of view this survey aims to retrace the steps of this debate and to provide some suggestions for future empirical researches

how big are potential welfare gains from international risksharing abstract there is extensive evidence that risksharing across countries is far from perfect some have attributed this to small benefits from risksharing gains from riskpooling that have been reported range from negligible to enormous this paper documents to what extent the results are sensitive to the parameterization of preferences the stochastic process of the endowment and its measurement we find that gains from risksharing are quite sizable for realistic assumptions about the underlying factors for oecd countries they are equivalent to a permanent increase in tradables consumption in the range of 1 1 to 3 5 for a 50 year horizon and 2 5 to 7 4 for a 100 year horizon

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

economic organization with limited communication this paper presents formal stylized representations of communication accounting systems oral assignment portable object written message and telecommunication systems are considered the environments that allow this formalization are characterized by spatial separation private information and a need to keep track of past actions transfers and shocks in environments that have spatial separation and private information beneficial multilateral arrangements can depend critically on agents ability to communicate to one another values of contemporary shocks and to keep track of histories of past transfers or past announced shocks this paper formalizes this idea and focuses on com

liquidity loanable funds and real activity abstract this paper develops a general equilibrium model of two traditional explanations of the monetary black box linking money and real activity the liquidity effect and the loanable funds effect these effects are modeled with a monetary production economy in which central bank injections of cash are funnelled into the economy through the credit market since only borrowers have direct access to the newly injected cash monetary injections cause nominal interest rates to fall if firms are borrowers then monetary injections also increase current and future real activity

deposit banks and the market for payment media this paper develops a model of bank deposit pricing with optimal consumer choices of spending shares among alternative media of exchange interpreting deposits as a tie in feature of the sale of bank payment services the paper shows that the wedge between consumer and social costs of currency use may reverse typical prescriptions regarding bank market structure and distortionary taxes on banks an explanation is offered for below cost bank service fees despite deregulated deposit interest rates while rate ceilings are shown to induce substitution into payment media with higher social costs copyright 1992 by ohio state university press

trend and cyclical decoupling new estimates based on spectral causality tests and wavelet correlations the issue of decoupling of emerging market economies emes especially in the asian region from the developments in advanced economies has become a subject of lively debate in recent years basically decoupling seems to comprise three sub hypotheses i growth spillovers from advanced countries to emes decreasing progressively in importance ii business cycles in emes becoming less synchronized with those of the advanced world and iii strengthening of growth spillovers and cyclical synchronization among the emes as a group the received literature fails to distinguish adequately between the trend and cyclical aspects of the decoupling relationship we resort to two frequency domain methods nonstationary spectral causality testing and wavelet correlations which seem to offer a neat separation of trend and cyclical decoupling based on a sample of seven emes from the asian region including the two large emes china and india we uncover strong evidence favouring both trend and cyclical decoupling

currency elasticity and banking panics theory and evidence existing models of banking panics contain no role for monetary factors and fail to explain why some banking systems experienced panics while others did not a monetary model is constructed where seasonal variations in the demand for liquidity and credit play a critical role in generating banking panics these panics occur when there are restrictions on the issue of currency in private banks but they do not occur if banks are unrestricted empirical evidence from canada and the united states for the period 1880 1910 is largely consistent with the predictions of the model

crises in competitive versus monopolistic banking systems we study a monetary general equilibrium economy in which banks exist because they provide inter temporal insurance to risk averse depositors a banking crisis is defined as a case in which banks exhaust their reserve assets this may but need not be associated with liquidation of a storage asset when such liquidation does occur the result is a real resource loss to the economy and we label this a costly banking crisis there is a monetary authority whose only policy choice is the long run constant rate of growth of the money supply and thus the rate of inflation under different model specifications the banking industry is either a monopoly bank or a competitive banking industry it is shown that the probability of a banking crisis may be higher either under competition or under monopoly this is shown to depend on the rate of inflation in particular if the nominal rate of interest rate of inflation is below above some threshold a monopolistic banking system will always result in a higher lower crisis probability thus the relative crisis probabilities under the two banking systems cannot be determined independently of the conduct of monetary policy we further show that the probability of a costly banking crisis is always higher under competition than under monopoly however this apparent advantage of the monopoly banking is strictly due to the fact that it provides relatively less valuable inter temporal insurance

search limited participation and monetary policy a model is developed that employs recent developments in the literature on search models of money to capture the distributional effects of monetary policy in a tractable way deterministic and stochastic versions of the model are studied money is not neutral and these nonneutralities persist whether or not the change in the money supply is anticipated or unanticipated at the optimum monetary policy is geared to correcting distortions in the search sector of the economy while correcting for the persistent effects of past monetary policy actions there is no consensus among macroeconomists concerning the role of monetary policy in the short run however an influential idea is that limited participation in financial markets is an important mechanism behind the short run macroeconomic effects of central bank actions that is there is a component of economic activity that is centralized and interconnected this economic activity involves financial transactions among banks and other financial intermediaries and the agents who hold the assets and liabilities of these financial intermediaries when the central bank injects outside money into the economy or withdraws it the economic agents who are immediately affected by the monetary injection or withdrawal are the participants in these centralized transactions other economic agents who are engaged in more decentralized and less interconnected transactions will not be affected directly by the first round effects of central bank actions thus there will be a distributional effect of monetary injections and withdrawals as first captured in heterogeneous agent models by grossman and weiss 1983 and rotemberg 1984 this distributional effect will matter in interesting ways for the price level nominal interest rates aggregate output foreign exchange rates and the distribution of consumption across the population the grossman weiss and rotemberg models are not analytically tractable because of the difficulty in tracking the distribution of wealth over time however lucas 1990 fuerst 1992 and alvarez and atkeson 1997 among others

exporting recessions international links and the business cycle abstract empirical evidence of decoupling typically focuses on declining business cycle correlations at low frequencies at higher frequencies business cycles strongly co move during recessions but are largely independent during non recessionary periods

how does globalization affect the synchronization of business cycles this paper examines the impact of rising trade and financial integration on international business cycle comovement among a large group of industrial and developing countries the results provide at best limited support for the conventional wisdom that globalization has increased the degree of synchronization of business cycles the evidence that trade and financial integration enhance global spillovers of macroeconomic fluctuations is mostly limited to industrial countries one striking result is that on average cross country consumption correlations have not increased in the 1990s precisely when financial integration would have been expected to result in better risk sharing opportunities especially for developing countries this abstract was borrowed from another version of this item

inflation targeting and business cycle synchronization abstract inflation targeting seems to have a small but positive effect on the synchronization of business cycles countries that target inflation seem to have cycles that move slightly more closely with foreign cycles thus the advent of inflation targeting does not explain the decoupling of global business cycles for two reasons indeed business cycles have not in fact become less synchronized across countries

bank competition and access to finance international evidence using a unique database for 74 countries and for firms of small medium and large size we assess the effect of banking market structure on the access of firms to bank finance we find that bank concentration increases obstacles to obtaining finance but only in countries with low levels of economic and institutional development a larger share of foreign owned banks and an efficient credit registry dampen the effect of concentration on financing obstacles while the effect is exacerbated by more restrictions on banks activities more government interference in the banking sector and a larger share of government owned banks

international spillovers in macrofinancial linkages and the decoupling phenomenon abstract this paper contributes to the debate on the decoupling of emerging economies ees from advanced economies aes by measuring how the resilience of ees to external shocks i e shocks spreading from aes has changed over time and whether ees are relatively more vulnerable to real or financial external shocks a time varying panel var model with factorisation of the coefficients was used to perform counterfactual experiments over a period of about 30 years for a large sample of countries allowing for time varying coefficients permitted the decoupling phenomenon to be examined as a slow moving evolution process over a long time rather than as a structural break at a specific moment the factorisation of coefficients allowed a large dynamic panel to be managed with interdependences across many countries consequently the experiment was more realistic in terms of evaluating the response of ees to shocks hitting the aes within a global framework the resilience of ees has improved over time however this increasing resilience was discontinuous over the approximately 30 year sample period tracing a wave path in the whole sample period the ees were relatively more vulnerable to credit shocks than to real ones this greater vulnerability increased over time and peaked in the last 5 years of the sample period

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

emerging economies in the 2000s real decoupling and financial recoupling the paper documents an intriguing development in the emerging world in the 2000s a decoupling from the business cycle of advanced countries combined with the strengthening of the co movements in the main emerging market assets that predates the synchronized sell off during the crisis in addition the paper tests the hypothesis that financial globalization to the extent that it creates a common global investor base for emerging markets could lead to a tighter asset correlation despite the weaker economic ties while an examination of the impact of alternative financial globalization proxies does not yield conclusive results a closer look at global emerging market equity and bond funds shows that the latter indeed foster financial recoupling during downturns reflecting the fact that they trade near their respective benchmarks and respond to withdrawals by liquidating holdings across the board

banking services for everyone barriers to bank access and use around the world using information from 193 banks in 58 countries the authors develop and analyze indicators of physical access affordability and eligibility barriers to deposit loan and payment services they find substantial cross country variation in barriers to banking and show that in many countries these barriers can potentially exclude a significant share of the population from using banking services correlations with bank and country level variables show that bank size and the availability of physical infrastructure are the most robust predictors of barriers further the authors find evidence that in more competitive open and transparent economies and in countries with better contractual and informational frameworks banks impose lower barriers finally though foreign banks seem to charge higher fees than other banks in foreign dominated banking systems fees are lower and it is easier to open bank accounts and to apply for loans on the other hand in systems that are predominantly government owned customers pay lower fees but also face greater restrictions in terms of where to apply for loans and how long it takes to have applications processed these findings have important implications for policy reforms to broaden access

a stable international monetary system emerges inflation targeting is bretton woods reversed a stable international monetary system has emerged since the early 1990s a large number of industrial and a growing number of developing countries now have domestic inflation targets administered by independent and transparent central banks these countries place few restrictions on capital mobility and allow their exchange rates to float the domestic focus of monetary policy in these countries does not have any obvious international cost inflation targeters have lower exchange rate volatility and less frequent sudden stops of capital flows than similar countries that do not target inflation inflation targeting countries also do not have current accounts or international reserves that look different from other countries this system was not planned and does not rely on international coordination there is no role for a center country the imf or gold it is durable in contrast to other monetary regimes no country has been forced to abandon an inflation targeting regime succinctly it is the diametric opposite of the post war system bretton woods reversed

the terms of trade the real exchange rate and economic fluctuations this paper examines the relationship between terms of trade and business cycles using a three sector intertemporal equilibrium model and a large multicountry database results show that terms of trade shocks account for nearly one half of actual gdp variability the model explains weak correlations between net exports and terms of trade the harberger laursen and metzler effect and produces large and weakly correlated deviations from purchasing power parity and real interest rate parity terms of trade shocks cause real appreciations and positive interest differentials although productivity shocks have opposite effects the puzzle that welfare gains of international asset trading are negligible is left unresolved copyright 1995 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

transportation costs and international trade in the second era of globalization while the precise causes of postwar trade growth are not well understood declines in transport costs top the lists of usual suspects however there is remarkably little systematic evidence documenting the decline this paper brings to bear an eclectic mix of data in order to provide a detailed accounting of the time series pattern of shipping costs the ad valorem impact of ocean shipping costs is not much lower today than in the 1950s with technological advances largely trumped by adverse cost shocks in contrast air shipping costs have dropped an order of magnitude and airborne trade has grown rapidly as a result as a result international trade has also experienced a significant rise in speed

monetary stability and liquidity crises the role of the lender of last resort we study an economy where agents are subject to liquidity demand shocks and banks arise endogenously to insure consumers against these shocks in this environment we evaluate the desirability of a lender of last resort who can provide liquidity loans to banks in distress in the absence of a lender of last resort the economy has a unique stationary equilibrium the introduction of unlimited and costless lender of last resort services allows the economy to achieve a steady state allocation that is pareto optimal however this economy also displays a continuum of hyperin ationary equilibria we then explore restrictions on the provision of lender of last resort services that rule out such monetary instability while preserving some of the e ciency obtained by unrestricted lender of last resort services when the lender of last resort charges an interest rate on liquidity loans the economy has a unique steady state equilibrium and when the interest rate charged is high enough no hyperin ationary equilibria arise finally when the lender of last resort faces an upper bound on loanable funds there is again a unique long run equilibrium and when the upper bound on loanable funds is small enough hyperin ationary equilibria are ruled out

retail bank deposit pricing an intertemporal asset pricing approach fundamentally spreads between market and deposit interest rates increase when interest rates rise and decline when rates fall recent empirical studies have found this phenomenon to be related to market concentration static equilibrium models are poorly equipped to explain this behavior in this paper the author applies an intertemporal asset pricing model incorporating bank deposits as a form of money in order to analyze the pricing behavior of a banking sector exercising market power his results extend the theoretical literature on deposit pricing and provide some insights into the behavior of interest rate spreads through time copyright 1995 by ohio state university press

banks and markets in a monetary economy abstract modern financial sectors consist of banks asset markets and a central bank this paper builds a model where these institutions provide different financial services and their interaction supports efficient allocations when one institution is missing equilibria are by construction inefficient the paper analyzes how interest rates and asset prices depend on the structure of the financial sector and characterizes the central bank policy that supports efficient allocations the analysis relies on the difference between liquidity and real shocks and relates the notion of liquidity used in this paper to the one adopted in other studies

understanding the evolution of world business cycles abstract this paper studies the changes in world business cycles during the period 1960 2003 we employ a bayesian dynamic latent factor model to estimate common and country specific components in the main macroeconomic aggregates output consumption and investment of the g 7 countries we then quantify the relative importance of the common and country components in explaining comovement in each observable aggregate over three distinct time periods the bretton woods bw period 1960 1 1972 2 the period of common shocks 1972 3 1986 2 and the globalization period 1986 3 2003 4 the results indicate that the common g 7 factor explains on average a larger fraction of output consumption and investment volatility in the globalization period than it does in the bw period

the economics of dowry and brideprice payments between families at the time of marriage existed during the history of most developed countries and are currently pervasive in many areas of the developing world these payments can be substantial enough to affect the welfare of women and a society s distribution of wealth recent estimates document transfers per marriage amounting to six times the annual household income in south asia rao 1993 and four times in sub saharan africa dekker and hoogeveen 2002 this paper first establishes some basic facts about the prevalence and magnitude of marriage payments it then discusses how such patterns vary across countries depending upon economic conditions societal structures institutions and family characteristics such payments have also evolved within societies over time for example in some periods such payments have risen sharply in some cases payments have shifted from the grooms sides to the brides and vice versa also property rights over such payments have sometimes shifted between marrying partners and parental generations economists who have only recently begun to work on the topic have focused on explaining these facts the second part of the paper addresses this economic literature though considerable insight into many of the facts has been gained many of the existing economic explanations are weakly convincing and many puzzles remain one crucial difficulty is that solid data in this field have been extremely rare the descriptions of marriage payments in this paper are synthesized from a patchwork of studies across periods places and even epochs and there are doubtless numerous cases which remain undocumented thus the paper

currency unions and international integration this paper characterizes the integration patterns of international currency unions such as the cfa franc zone we empirically explore different features of currency unions and compare them to countries with sovereign monies by examining the criteria for mundellos concept of an optimum currency area we find that members of currency unions are more integrated than countries with their own currencies for instance we find that currency union members have more trade and less volatile real exchange rates than countries with their own monies business cycles are more highly synchronized across currency union countries than across countries with sovereign monies

the myth of decoupling the decoupling hypothesis is the idea that business cycles in emerging market economies have become more independent from business cycles in advanced economies in recent years decoupling essentially amounts to a structural break in the degree of business cycle interdependence between the two groups of economies and it can be tested as such we develop an innovative measure of business cycle interdependence based on the euclidean distance available at the annual frequency which allows for a proper test for a structural break in a graphical setup we also make use of a standard econometric test both approaches point to the same conclusion there has been no decoupling in recent years if anything the degree of business cycle interdependence has become stronger

clubmed cyclical fluctuations in the mediterranean basin we investigate the similarities of macroeconomic fluctuations in the mediterranean basin and their convergence a model with three geo political indicators covering the west the east and the mena portions of the mediterranean characterizes well the historical experience since the early 1980 convergence and divergence coexist in the region and are reversible except for the west domestic cyclical fluctuations are still due to national and idiosyncratic causes the outlook for the next few years looks rosier for the mena and the east blocks than for the west

the price concentration relationship in banking the commonly observed positive correlation between market concentration and profitability may be explained by noncompetitive pricing behavior as argued by the structure performance hypothesis or by the greater efficiency of firms with dominant market shares as argued by the efficient structure hypothesis by examining the price concentration relationship instead of the profit concentration relationship this paper tests the structure performance hypothesis in a manner that excludes the efficient structure hypothesis as an alternative explanation of the results the results strongly support the structure performance hypothesis and are robust with respect to model specification measurement of concentration and econometric technique copyright 1989 by mit press
