estimating the impact of currency unions on trade solving the glick and rose puzzle does leaving a currency union reduce international trade this paper uses a historical approach to re examine the puzzling large apparent impact of currency unions on trade i find that the early time series estimates were driven by the gradual decaying of colonial trade ties and other major geopolitical factors including warfare communist takeovers and ethnic cleansing episodes my methodology which carries lessons for other uses of gravity equations in policy analysis yields point estimates of currency unions on trade that are not statistically distinct from zero

to float or to fix evidence on the impact of exchange rate regimes on growth we study the relationship between exchange rate regimes and economic growth for a sample of 183 countries over the post bretton woods period using a new de facto classification of regimes based on the actual behavior of the relevant macroeconomic variables in contrast with previous studies we find that for developing countries less flexible exchange rate regimes are associated with slower growth as well as with greater output volatility for industrial countries regimes do not appear to have any significant impact on growth the results are robust to endogeneity corrections and a number of alternative specifications borrowed from the growth literature

fixed currency regimes and the time pattern of trade effects abstract this paper assesses duration specific treatment effects of fixed currency regimes on bilateral trade along a duration path of up to 25 years we find that country pairs with fixed exchange rate regimes trade more but only after about 8 years

limit order submission strategies under asymmetric information abstract this paper provides evidence that informed traders dominate the response of limit order submissions to shocks in a pure limit order market in the market we study informed traders are highly sensitive to spreads volatility momentum and depth by contrast uninformed traders are relatively insensitive to all these market conditions the dominance of the informed over limit order submissions is magnified by contrasts between them and the uninformed in the use of aggressively priced limit orders

bilateral trade and the eurozone evidence from new member countries the question of whether and how much currency unions increase bilateral trade among their members has garnered much attention since rose s seminal article the answer is as pertinent now as ever for both the eurozone s existing and future members as the financial crisis shook the very foundations of the european monetary union emu and brought its shortcomings into the spotlight this paper analyses the issue using the gravity equation with country pair and time fixed effects for a sample of the four new members of the emu slovakia slovenia malta and cyprus which has to the author s knowledge not been studied thus far due to their recent joining and controls drawn from the european union this paper finds a positive relationship between joining the emu and trade with emu partners but not with non emu partners

limit order book as a market for liquidity we develop a dynamic model of an order driven market populated by discretionary liquidity traders these traders must trade yet can choose the type of order and are fully strategic in their decision traders differ by their impatience less patient traders demand liquidity more patient traders provide it three equilibrium patterns are obtained the pattern is determined by three parameters the degree of impatience of the patient traders which we model as the cost of execution delay in providing liquidity their proportion in the population which determines the degree of competition among the liquidity providers and the tick size which is the cost of the minimal price improvement despite its simplicity the model generates a rich set of empirical predictions on the relation between market parameters time to execution and spreads we argue that the economic intuition of this model is so basic its main results must be robust in much more general models

rethinking ecosystem services to better address and navigate cultural values ecosystem service approaches have become a prominent basis for planning and management cultural services and non use values are included in all major typologies and present some of the most compelling reasons for conserving ecosystems though many barriers exist to their explicit characterization the values that conform least well to economic assumptions variously lumped together with as cultural services have proven elusive in part because valuation is complicated by the properties of intangibility and incommensurability which has in turn led to their exclusion from economic valuation we argue that the effectiveness of the ecosystem services framework in decision making is thwarted by i conflation of services values and benefits and ii failure to appropriately treat diverse kinds of values we address this challenge by 1 distinguishing eight dimensions of values which have implications for appropriate valuation and decision making 2 demonstrating the interconnected nature of benefits and services and so the ubiquity of intangible values 3 discussing the implications of these propositions for ecosystem services research and 4 outlining briefly a research agenda to enable decision making that is ecologically appropriate and socially just because many ecosystem services co produce cultural benefits full characterization of services must address non material values through methods from diverse social sciences

honey the currency union effect on trade hasn t blown up as the value of real bilateral trade between countries i and j at time t cu is a dummy variable which is unity if i and j sharethe same currency at time t z is a vector of controls given by an augmentedgravity model c are the associate nuisance coefficients and is a hopefully well behaved residual my chief finding was that was large and robust mypoint estimate was 1 2 implying that currency union is associated with atripling since exp 1 2 3 of trade in his paper in this issue volker nitsch provides three pieces of value added first he finds and corrects a number of data errors in my original data set second he shows that adding extra controls to my empirical setup disaggregating bycurrency unions and adjusting for missing data affects the results he concludesthat the effect of currency union on trade is smaller than my original estimates has not been reliably estimated and may be zero

de facto exchange rate arrangement tightness and bilateral trade flows abstract this paper estimates the effect of switching into and out of 14 different modes of exchange rate arrangements on bilateral exports between 1948 and 2001 in the world economy increasing the exchange rate arrangement tightness by one degree in the classification of reinhart and rogoff reinhart carmen m and kenneth s rogoff 2004 the modern history of exchange rate arrangements a reinterpretation quarterly journal of economics 119 1 48 increases bilateral trade flows by about 2 4 as compared to their initial level

so what orders do informed traders use we present a simple glosten milgrom type equilibrium model to analyze the decision of informed traders on whether to use limit or market orders we show that even after incorporating an order s price impact not only may informed traders prefer to use limit orders but the probability that they submit limit orders can be so high that limit orders convey more information than market orders we further show that the horizon of the private information is critical for this decision and is positively related to the use of limit orders our empirical analysis using torq suggests that informed traders do prefer limit orders to market orders and that limit orders are indeed more informative our model is in contrast to the literature that assumes that informed traders use market orders only and the literature that examines the limit order versus the market order decision of uninformed traders

financial integration gdp correlation and the endogeneity of optimum currency areas the paper analyses the relationship between trade financial integration and business cycle synchronization in the euro area the introduction of the euro has had a noticeable impact on european financial markets evidence that capital market integration exerts a positive effect on output correlation has two major implications first it corroborates the hypothesis of the endogeneity of optimum currency areas whereby after joining a monetary union countries better meet standard oca criteria second it provides european policy makers with yet another reason to pursue financial integration in the euro area and in prospective members as well

games of monetary and fiscal interactions in the emu abstract this paper constructs various models of the emu and ecb when member countries have different objectives voting in pursuit of national interest can yield moderate and stable inflation the metaphor of walsh type contracts implements a monetary policy rule that averages the member countries most preferred rules in a repeated relationship where a country suffering a large adverse shock can use political bargaining to subvert the ecb s commitment the optimal rule should incorporate some flexibility to forestall that finally freedom of national fiscal policies undermines the ecb s monetary commitment this may justify fiscal constraints like the stability and growth pact

limit order revisions abstract this paper empirically examines limit order revisions and cancellations which contribute to a significant portion of the order activity in many order driven markets we document that limit orders are more likely to be revised or cancelled if they are large and near the bid ask quote we show that order revisions generate net economic benefits to traders our evidence shows strong links between these activities and limit order submission risk using bid ask spread volatility and post event return as proxies we also find that these activities are less intense when the opportunity cost to monitor a stock is high such as during lunch hours or when stock volume relative to the entire market is low

out in the cold iceland s trade performance outside the european union and european monetary union although entering currency and customs unions involve both costs and benefits an increasing body of research is finding that the benefits in terms of international trade creation are remarkably large focusing simply on the european monetary union emu rather than the broad range of currency unions studied by other authors we find that the trade impact of emu is smaller but still substantial our findings suggest that the iceland s trade could increase by about 60 and that the trade to gdp ratio could rise by 12 percentage points should iceland join the european union and emu copyright 2006 oxford university press

currency unions and trade the effect is large the impact of a common currency on trade can be grossly mismeasured if countries that belong to currency unions are systematically different from those that do not and if the relationship between trade and its observable determinants is complex i argue that such complications are plausible and likely to distort the empirical results of a recent economic policy paper by andrew rose issue 30 2000 pp 7 45 using techniques designed to be robust in this situation i find that the effects of common currency on international trade are considerably less dramatic and much less precisely estimated copyright cepr ces msh 2001

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

do currency unions deliver more economic integration than fixed exchange rates evidence from the franc zone and the eccu in this article we develop a model to identify determinants of macroeconomic integration in the african franc zone and in dollar pegging caribbean countries including members of the east caribbean currency union these two groups of countries each comprise states using several different local currencies on the one hand the uemoa cfa franc and the cemac cfa franc both pegged to the euro on the other the eccu dollar and other national dollar pegged currencies the purpose of the analysis is to distinguish the effect of monetary union on macroeconomic integration from the effect of pegging to a common oecd currency

complementing emu rethinking cohesion policy under emu the less competitive regions of the eu usually assumed to be peripheral have been widely expected to lose ground yet it is the core of the eu that so far has appeared to have suffered from the advent of the euro this paper looks at the processes behind regional divergence in the eu and presents evidence on recent and prospective trends as emu is consolidated bearing in mind that the imminent enlargement of the eu will radically change the political economy of the eu s efforts to assure cohesion policy issues are then discussed looking forward to the next renegotiation of the structural funds it is argued that difficult decisions have to be taken about the extent and character of eu policy the option of an open method of coordination for cohesion policy is put forward as a means of resolving some of the hard choices

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

endogenous oca analysis and the early euro experience some have argued that the endogenous responses to the formation of a currency area are so strong that one need not worry about optimum currency area conditions ex ante we argue that this is much too strong a conclusion we draw on a number of recent studies to evaluate the endogeneity experiences of the eurozone in three major areas trade flows business cycle synchronisation and structural reforms to improve labour and product market flexibility simple before and after comparisons are insufficient for analysis of endogeneity the experiences of non euro western european economies suggest that broader trends also had considerable influence on trade and business cycle patterns while trade rose substantially within the eurozone it also rose with and among other european economies we argue that political economy considerations tend to dampen the magnitude of endogeneity efforts on structural reforms and that meeting conditions for entry may be a more powerful mechanism in this than are subsequent endogenous responses we also discuss a number of areas for further research

workers of the world unite franchise extensions and the threat of revolution in europe 1820 1938 abstract we test the hypothesis that the extension of the voting franchise in europe was related to the threat of revolution we contend that international diffusion of regime contention and information about revolutionary events happening in neighboring countries generate the necessary variation in the perceived threat of revolution using two samples of european countries covering the period from 1820 to 1938 we find robust evidence which is consistent with the threat of revolution hypothesis we also find some evidence that war triggered suffrage reform

trade creation and diversion revisited accounting for model uncertainty and natural trading partner effects summary the effect of preferential trade agreements ptas on trade flows is subject to model uncertainty stemming from the diverse and even contradictory effects suggested by the theoretical pta literature the existing empirical literature has produced remarkably disparate results and the wide variety of empirical approaches reflects the uncertainty about the correct set of explanatory variables that ought to be included in the analysis to account for the model uncertainty that surrounds the validity of the competing pta theories we introduce bayesian model averaging bma to the pta literature statistical theory shows that bma successfully incorporates model uncertainty in linear regression analysis by minimizing the mean squared error and by generating predictive distributions with optimal predictive performance once model uncertainty is addressed as part of the empirical strategy we find strong evidence of trade creation trade diversion and open bloc effects our results are robust to a range of alternative empirical specifications proposed by the recent pta literature copyright 2010 john wiley sons ltd

one money one market the effect of common currencies on trade currency unions their dramatic effect on international trade a gravity model is used to assess the separate effects of exchange rate volatility and currency unions on international trade the panel data bilateral observations for five years during 1970 90 covering 186 countries includes 300 observations in which both countries use the same currency i find a large positive effect of a currency union on international trade and a small negative effect of exchange rate volatility even after controlling for a host of features including the endogenous nature of the exchange rate regime these effects statistically significant imply that two countries sharing the same currency trade three times as much as they would with different currencies currency unions like the european emu may thus lead to a large increase in international trade with all that that entails andrew rose

benchmarking the sustainability performance of the brazilian non gm and gm soybean meal chains an indicator based approach abstract a commonly accepted approach for measuring the sustainability of agricultural products is the first step toward treating traded products differentially according to their sustainability if we were able to measure sustainability business stakeholders could optimize food production chains consumers could demand products based on reduced environmental and social impacts and policy makers could intervene to meet the growing demand for food in a context of environmental conservation population growth and globalization we proposed to measure profit adjusted for the negative externalities of production as a promising single metric for benchmarking products in terms of their relative sustainability the adjusted profit differences between different products are then assessed by means of the bennet total factor productivity tfp indicator and the total price recovery tpr indicator to highlight areas for potential sustainability improvement to illustrate the usefulness of the indicator based approach we assessed the relative sustainability of two brazilian conventional soybean meal chains non genetically modified non gm and genetically modified gm chains based on the results we indicated potential areas for sustainability improvement sustainability issues included in the assessment were profitability global warming potential eutrophication potential environmental toxicity farmworker toxicity consumer toxicity deforestation and loss of employment results showed that the non gm soybean meal chain is more sustainable than the gm chain higher adjusted profit due to higher tfp and favorable prices especially for outputs however both chains require joint efforts to address their economic environmental and social deficiencies these efforts should focus on providing technical and high quality assistance to reduce biocide use and improving transportation the analysis in this study could be extended by undertaking a comparative assessment of the sustainability performance of major soybean meal producers i e united states argentina china and brazil the approach proved to be a promising benchmarking tool for agricultural trade flows it allows an integrated assessment of the dimensions of sustainability along food chains that is sufficiently flexible to compare the sustainability level of various biomass stocks that are produced in different locations and in a variety of environmental and socio economic contexts nevertheless it requires consensus on which components of sustainability are to be assessed

sense and sustainability sustainability as an objective in international agricultural research abstract this paper first discusses how to use sustainability as a criterion by which to evaluate agricultural research then illustrates the difficulties inherent in applying the criterion and finally draws implications for international agricultural research seven propositions relating to sustainability are stated agricultural researchers are urged to a recognize the importance of the sustainability of agricultural systems b devise appropriate ways to measure sustainability c empirically examine the sustainability of some well defined cropping or farming systems d define the externalities that exist in such systems and e develop methods to measure those externalities

native language spoken language translation and trade we construct new series for common native language and common spoken language for 195 countries which we use together with series for common official language and linguistic proximity in order to draw inferences about 1 the aggregate impact of all linguistic factors on bilateral trade 2 the separate role of ease of communication as distinct from ethnicity and trust and 3 the contribution of translation and interpreters to ease of communication the results show that the impact of linguistic factors all together is at least twice as great as the usual dummy variable for common language resting on official language would say in addition ease of communication plays a distinct role apart from ethnicity and trust and so far as ease of communication enters translation and interpreters are significant finally emigrants have much to do with the role of ethnicity and trust in linguistic influence

banking market integration in the sadc countries evidence from interest rate analyses this study investigates the state development and drivers of banking market integration in the member countries of the southern african development community sadc a principal component analysis pca of national retail interest rates indicates increasing integration in loan and deposit markets these integration processes are not developing uniformly and we can identify a convergence club when investigating the interest rate pass through from central bank onto retail rates for this convergence club we find both genuine and monetary integration driven processes though the latter dominate we thus conclude that a selective expansion of the common monetary area cma is possible

long run growth and volatility which source really matters the aim of the article is to analyse the relationship between long run growth and business cycle volatility in particular the main purpose of this article is to identify which source of volatility is most detrimental to growth using cross country data from 1970 to 2000 and several indicators of volatility such as inflation exchange rate government expenditure output and investment volatility this article shows that although all these measures of volatility are remarkably harmful for growth business cycle investment volatility is the main source that hampers long run growth this relation is robust to different measures of business cycle and to different sub samples of countries

evaluating the econometric evaluations of training programs with experimental data this paper takes the results of an employment and training program thatwas run as a field experiment in which the participants were randomlyassigned into a treatment or a control group and compares these results to the estimates that might have been produced by an econometrician who evaluated the program using the same econometric procedures that have been used in the program evaluation literature this comparison shows that many of these econometric procedures fail toreplicate the experimentally determined results and suggests that researchers should be aware of the potential for specification errorsin other nonexperimental evaluations copyright 1986 by american economic association

limit orders depth and volatility evidence from the stock exchange of hong kong we investigate the role of limit orders in the liquidity provision in a pure orderdriven market results show that market depth rises subsequent to an increase in transitory volatility and transitory volatility declines subsequent to an increase in market depth we also examine how transitory volatility affects the mix between limit orders and market orders when transitory volatility arises from the ask bid side investors will submit more limit sell buy orders than market sell buy orders this result is consistent with the existence of limit order traders who enter the market and place orders when liquidity is needed

north south and distance in the gravity model abstract it is generally assumed that distance in the gravity model strictly reflects frictions impeding bilateral trade however distances north south could also reflect differences in factor endowment that provide opportunities for profitable trade this paper investigates the hypothesis that if we control for distance in the ordinary sense differences north south promote international trade the hypothesis receives ample support moreover the significance of differences north south survives a battery of robustness tests concerning period distinctions between differences in latitude north north north south and south south and controls for other measures of differences in factor endowment such as differences in per capita output and differences in average temperature rainfall and seasonal range in temperature the impact of differences north south on bilateral trade has also been falling this decline in turn might be partly responsible for the weakening of the influence of distance that has been occurring since world war ii this last hypothesis receives confirmation as well finally the paper examines the impact of internal distance and remoteness on trade since both variables are country specific this is done by studying their impact on the country fixed effects themselves in the earlier estimates internal distance turns out to have a far greater impact than remoteness by an order of 10

the costs and determinants of order aggressiveness abstract this paper examines the costs and determinants of order aggressiveness aggressive orders have larger price impacts but smaller opportunity costs than passive orders price impacts are amplified by large orders small firms and volatile stock prices to minimize the implementation shortfall the optimal strategy is to enter buy sell orders at the bid ask aggressive buy sell orders tend to follow other aggressive buy sell orders and occur when bid ask spreads are narrow and depth on the same opposite side of the limit book is large small aggressive buys are more likely than sells to be motivated by information

distance language religion and the law of one price evidence from canada and nigeria we examine the impact of physical distance language and religion on law of one price lop deviations across interwar canadian and modern nigerian cities the data comprise monthly average retail prices for narrowly defined goods collected by national statistical agencies we find that differences in the fraction of the city population sharing a common language and religion have a significant impact on lop deviations the impact of language differences is consistent with a recently developed theory in which both trade costs and differences in signal noise ratios contribute to lop deviations

exchange rate regimes and international trade evidence from the classical gold standard era in this paper we show that the spread of the classical gold standard in the late nineteenth century increased international trade flows this positive effect was compounded whenever a group of countries formed a monetary union applying the gravity model of trade to more than 1 100 country pairs during the 1870 1910 period we find that two countries on gold would trade 60 percent more with each other than with countries on a different monetary standard moreover a monetary union would more than double bilateral trade flows our findings are relevant for current discussions on alternative monetary arrangements for the twenty first century

publicly funded uk agricultural r d and social total factor productivity most studies concerned with measuring the rate of return to publicly funded agricultural r d investment have found high returns suggesting under investment and calls for increased expenditure have been common however the evaluation of returns tends to measure the effect of research expenditure against growth in total factor productivity tfp based on market inputs and outputs when compared against growing public unease over the environmental effects of pursuing agricultural productivity growth tfp indices become a misleading measure of growth this paper integrates some non market components into the tfp index the costs of two specific externalities of agricultural production namely fertiliser and pesticide pollution are integrated in a tfp index constructed for the period 1948 1995 this adjusted or social tfp index is measured against uk public r d expenditures the rates of return to agricultural r d are reduced by using the social as opposed to the traditional tfp index whilst both remain at justifiable levels previous studies appear to have over estimated the effect of agricultural r d expenditures furthermore with changes in policy towards more socially acceptable but non productivity enhancing outcomes such as animal welfare rural diversification and organic farming the future framework for analysing returns to agricultural r d should not be so dependent on productivity growth as an indicator of research effectiveness

trade spill overs of fiscal policy in the european union a panel analysis we explore the international spillovers from fiscal policy shocks via trade in europe a fiscal expansion stimulates domestic activity which leads to more foreign exports and hence higher foreign output to quantify this we combine a panel var model in government spending net taxes and gdp with a panel trade model on average a public spending increase equal to 1 of gdp implies 2 3 more foreign exports over the first two years the corresponding figure for an equal size net tax reduction is 0 6 both estimates are statistically significant as far as the effect on foreign activity is concerned a 1 of gdp spending increase net tax reduction in germany on average raises gdp of trading partners by 0 23 0 06 over the first two years these figures are likely to form lower bounds for the actual effects and suggest that it may be worthwhile to further investigate the benefits from coordinated fiscal expansions contractions in response to european wide cyclical downturns upswings

the nonlinear impact of currency unions on bilateral trade abstract most gravity model specifications assume that a currency union varies the level of bilateral trade between members by a constant proportion we demonstrate that a common currency also alters the slope of the relationship between bilateral trade and member country gdps

stealth trading which traders trades move stock prices usingaudit trail data for a sample of nyse firms we show that medium size trades are associated with a disproportionately large cumulative stock price change relative to their proportion of all trades and volume this result is consistent with the predictions of barclay and warner s 1993 stealth tradinghypothesis we find that the source of this disproportionately large cumulative price impact of medium size trades is trades initiated by institutions this result is robust to various sensitivity checks our findings appear to confirm street lore that institutions are informed traders 2001 elsevier science s a all rights reserved

informed traders and limit order markets abstract we consider a dynamic limit order market in which traders optimally choose whether to acquire information about the asset and the type of order to submit we numerically solve for the equilibrium and demonstrate that the market is a volatility multiplier prices are more volatile than the fundamental value of the asset this effect increases when the fundamental value has high volatility and with asymmetric information across traders changes in the microstructure noise are negatively correlated with changes in the estimated fundamental value implying that asset betas estimated from high frequency data will be incorrect

spanning the institutional abyss the intergovernmental network and the governance of foreign direct investment global economic transactions such as foreign direct investment fdi must extend over an institutional abyss between the jurisdiction and therefore protection of the states involved intergovernmental organizations igos represent an important attempt to span this abyss the authors use a network approach to demonstrate that the connections between two countries through joint membership in the same igos are associated with a large positive influence on the fdi that flows between them moreover they show that this effect occurs not only in the case of connections through economic igos but also through those with social and cultural mandates this demonstrates that relational governance is important and feasible in the global context even for the most risky transactions the authors also examine the interdependence between the igo network and the domestic institutions of states social and cultural igo connections do more and economic igo connections less to increase fdi when the target country is mo

trade costs 1870 2000 what has driven trade booms and trade busts in the past century and a half was it changes in global output or in the costs of international trade to address this question we derive a micro founded measure of aggregate bilateral trade costs based on a standard model of trade in differentiated goods these trade costs gauge the difference between observed bilateral trade and frictionless trade in terms of an implied markup on retail prices of foreign goods thus we are able to estimate the combined magnitude of tariffs transportation costs and all other macroeconomic frictions that impede interna tional trade but that are inherently difficult to observe we use this measure to examine the growth of global trade between 1870 and 1913 its retreat from 1921 to 1939 and its subsequent rise from 1950 to 2000 we find that trade cost declines explain roughly 55 percent of the pre world war i trade boom and 33 percent of the post world war ii trade boom while a precipi tous rise in trade costs explains the entire inter

on the distribution of exchange rate regime treatment effects on international trade abstract this paper provides evidence of heterogeneous treatment effects on trade for six different types of exchange rate regime transitions utilizing data on 218 643 country pair year observations all together previous research mainly focused on the currency union effect on trade and widely assumed that country pairs with identical observable characteristics receive the same effect we test the hypothesis of a homogeneous treatment effect empirically and find substantive statistical support for the presence of effect heterogeneity moreover we characterize the probability distribution of effect heterogeneity among observationally equivalent country pairs by way of a random coefficients model we estimate selected features of the empirical distributions of the treatment effects for each of the six different types of exchange rate regime transitions under two different sets of assumptions about the probability distribution of effect heterogeneity our findings suggest that the immediate effects on trade from switching to an exchange rate regime different from the one in the outset have wide waists and exhibit large positive extreme values we estimate the probability of two countries to experience an immediate positive effect on the growth of bilateral trade due to the adoption of any new exchange rate regime tighter or not to be approximately one half

competition signaling and non walking through the book effects on order choice abstract we investigate the effects of competition and signaling in a pure order driven market and examine the trading patterns of agents when walking through the book is not allowed our results suggest that the variables capturing the cost of a large market order are not informative for an impatient trader under this market mechanism we also document that the competition effect is not present only at the top of the book but persistent beyond the best quotes moreover it dominates the signaling effect for both a limit order and a market order trader finally we show that institutional investors order submission strategies are characterized by only a few pieces of the limit order book information this is consistent with informed traders placing orders based on their own private valuations rather than the state of the book

the mirage of exchange rate regimes for emerging market countries this paper argues that much of the debate on choosing an exchange rate regime misses the boat it begins by discussing the standard theory of choice between exchange rate regimes and then explores the weaknesses in this theory especially when it is applied to emerging market economies it then discusses a range of institutional traits that might predispose a country to favor either fixed or floating rates and then turns to the converse question of whether the choice of exchange rate regime may favor the development of certain desirable institutional traits the conclusion from the analysis is that the choice of exchange rate regime is likely to be of second order importance to the development of good fiscal financial and monetary institutions in producing macroeconomic success in emerging market countries this suggests that less attention should be focused on the general question whether a floating or a fixed exchange rate is preferable and more on these deeper institutional arrangements a focus on institutional reforms rather than on the exchange rate regime may encourage emerging market countries to be healthier and less prone to the crises that we have seen in recent years

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

disaggregated trade and disaggregated currency unions a ranking of common currency effects andrew rose has long argued that a common currency has a large effect on increasing trade recently rose has called into question the reliability of this conclusion as new techniques have emerged for estimating gravity equations this article uses the sector specific gravity model developed by anderson and yotov 2010a to investigate if disaggregated trade can provide a reliable estimate of a common currency s effect disaggregating trade alone is insufficient to obtain a reliable estimate of a currency union regardless of econometric technique when the effect of a common currency on trade is uniform across all unions disaggregating the universe of currency unions with individual effects provides a reliable ranking of currency unions independent of estimation method by the effect that each union s currency has on increasing trade these rankings differ across sectors

defying the law of gravity the political economy of international migration bilateral flows of international migrants exhibit tremendous variance both across destination countries and over time to explain this variance studies of international migration tend to focus on economic determinants such as income differentials or on social conditions such as the presence of coethnics in certain destination countries the authors argue that migration is driven not solely by economic or social determinants rather the political environment across destinations plays a substantively large role in influencing bilateral migration flows they test the importance of the political environment citizenship rights and the prominence of right wing parties using data on migration flows from 178 origin countries into 18 destination countries over the period 1980 2006 they find even after controlling for a variety of economic social policy and international variables that variation in political environments across time and destination plays a key role in observed patterns of international migration

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
