economic determinants of free trade agreements abstract the purpose of this study is to provide the first systematic empirical analysis of the economic determinants of the formation of free trade agreements ftas and of the likelihood of ftas between pairs of countries using a qualitative choice model we develop this econometric model based upon a general equilibrium model of world trade with two factors of production two monopolistically competitive product markets and explicit intercontinental and intracontinental transportation costs among multiple countries on multiple continents the empirical model correctly predicts based solely upon economic characteristics 85 of the 286 ftas existing in 1996 among 1431 pairs of countries and 97 of the remaining 1145 pairs with no ftas

relaxing intertemporal separability a rational habits model of labor supply estimated from panel data this article relaxes the assumption of separability of preferences over time that although implausible is usually maintained in life cycle labor supply models an empirically tractable rational habits model is specified and estimated on the basis of a 10 year sample of men from the michigan panel of income dynamics the effect of past hours of work in determining current hours decisions is found to be very important and well determined having allowed for permanent individual differences and for time effects

annual hours and weeks in a life cycle labor supply model canadian evidence on male behavior estimates of the intertemporal labor supply behavior of males in canada using micro data are reported individuals make the intertemporal labor supply decision on the basis of annual hours and weeks precision of the parameter estimates is improved by using tenure variables as instruments for the wage further the age and tenure variables are allowed to have taste parameters in the structural equations the evidence suggests that this is required only for the two age variables elasticity evidence suggests that evolutionary changes in the wage cause changes in the number of weeks with the elasticity being 0 6 and statistically significant

asymmetric price adjustment and economic fluctuations this paper considers a possible explanation for asymmetric adjustment of nominal prices the authors present a menu cost model in which positive trend inflation causes firms relative prices to decline automatically between price adjustments in this environment shocks that raise firms desired prices trigger larger price responses than shocks that lower desired prices the authors use this model of asymmetric adjustment to address three issues in macroeconomics the effects of aggregate demand the effects of sectoral shocks and the optimal rate of inflation copyright 1994 by royal economic society

on the price of recreation goods as a determinant of male labor supply we examine whether and how variations in the price of recreation goods influence men s allocation of market work for the united states individual level data are combined with metropolitan area level price indices to estimate the male elasticity of intertemporal substitution of market work with respect to the price of recreation goods which is found around 0 16 and statistically significant the allocation of market work in response to changes in the price of recreation goods would create movements in the output of an economy moreover it could contribute toward explaining the emerging differences in work and leisure between the united states and europe

testing misspecified cointegrating relationships the powers of various tests for cointegration are compared in an experimental design where there is a possible mismatch between the variables used in the construction of the tests and the variables entering the true cointegrating vector s

free trade agreements in the americas are the trade effects larger than anticipated this paper argues that the competitive liberalisation of national governments of the past several decades reflects national governments expectations of larger trade impacts from regional economic integration agreements eias than typical ex ante economic models have suggested moreover we show that previous typically cross section ex post empirical evaluations of the effects of eias on trade have seriously over or underestimated the effects partly due to ignoring the endogenous self selection bias of country pairs into eias accounting for this bias we find that economic integration agreements in the americas have had much larger impacts on trade over the period 1960 2000 than previously found and the ex post estimates are less fragile than those in earlier cross section analyses the results shed further light on understanding the causes and consequences of the growth of regionalism in the world

estimating the effects of free trade agreements on international trade flows using matching econometrics abstract this paper provides the first cross section estimates of long run treatment effects of free trade agreements on members bilateral international trade flows using nonparametric matching econometrics our nonparametric cross section estimates of ex post long run treatment effects are much more stable across years and have more economically plausible values than corresponding ols cross section estimates from typical gravity equations we provide plausible estimates of the long run effects of membership in the original european economic community eec and the central american common market cacm between 1960 and 2000 and the estimates confirm anecdotal reports of these agreements effectiveness

a model of labor supply fixed costs and work schedules abstract to analyze labor supply allocations we propose a three dimensional labor supply framework that distinguishes between hours worked per day days worked per week and workweeks individuals make labor supply choices given heterogeneous schedule dependent fixed costs of work the three margins are not perfect substitutes leisure on days not worked in a workweek has the largest weight in preferences leisure on weeks off has the smallest weight we use the model to analyze heterogeneous response to changes in fixed costs schedule flexibility and restrictions on weekly hours fixed costs of work affect response to each policy and determine associated losses

on the relationship between the breadth of preferential trading arrangements and trade flows this paper uses matching econometrics to extend the literature investigating the impact of preferential trading arrangements ptas on goods trade flows heterogeneity in ptas is accounted for through a provision count index derived from data provided in a recent world bank study pta formation now involves two separate sequential decisions first whether two trading partners should form a pta and second if they do how broad that agreement should be we find our explanatory variables are significant for both decisions but often have opposing effects on each using matched pta and non pta groups of country pairs we estimate a dose response function which indicates that arrangements with few provisions and arrangements with many provisions do not appear to have a significant impact on goods trade flows between their members ptas in an intermediate range are shown to have a significant positive effect we then relate these outcomes to the actual content of the ptas using the concept of provision intensity

adjustment costs inventories and output this paper analyzes the optimal adjustment strategy of an inventory holding firm facing price and quantity adjustment costs in an inflationary environment the model nests both the original menu cost model that allows production to be costlessly adjusted and the later model that includes price and quantity adjustment costs but rules out inventory holdings it is shown that the firm s optimal adjustment strategy may involve stockouts at low inflation rates output is inversely related to the inflation rate and the length of time demand is satisfied increases with the demand elasticity but decreases with the storage cost and the real interest rate

inflation relative prices and their skewness the results are presented of an empirical study on the extent of the skewness of price changes across products for nine european countries skewness may arise from product specific shocks or high costs in undertaking price changes leading to irregular though unusually large price changes hypotheses are established as to the nature of such skewness and results provided it is argued that our concern might also be with how skewness changes in response to inflation this is modelled and results are provided which incorporate tests as to the response when inflation is increasing and falling the empirical results are of interest not only in highlighting features of inflation but also for their implications for consumer price indices

implicit contracts life cycle labor supply and intertemporal substitution the implicit contract model is a serious alternative to the spot market interpretation of the labor market however its usefulness has been limited because the wage is unobserved and hence it has not been possible to estimate an intertemporal frisch supply elasticity for the model using microdata in this article we show that one can estimate this elasticity from microdata within the context of the implicit contract model under relatively weak assumptions based on consumer theory we implement our approach on two micro data sets and for both obtain a reasonably precise elasticity estimate of approximately 1 0

heterogeneous trade agreements wto membership and international trade an analysis using matching econometrics this article explores the heterogeneous effects of trade agreements tas and world trade organization wto membership on the volume of international trade we extend baier and bergstrand s 2009a application of matching econometrics by distinguishing between different types of tas and wto participation and account for the endogenous nature of trade policy for a panel data set covering 1960 2005 and 187 countries we find that the treatment effect on international trade systematically varies with the type of ta and wto membership

weather variations and international trade in this paper i investigate the effect of weather variations in the exporter and importer countries separately as well as a the difference between weather variations in both countries on bilateral trade flows the analysis is done at the country sectoral and product levels worldwide and over the 1992 2014 period i find a negative effect of temperature variations in the exporter country and in the difference between exporter and importer countries on bilateral trade at the country level at the product level both negative and positive effects arise but the negative effect of temperature dominates the temperature effects are on the agricultural and manufacturing sectors especially in the textile and metals sectors i show that possible channels are the impact of temperature on output and labour productivity the negative impacts are larger in exporter countries that are closer to the equator that have lower quality of institutions and that export to more remote countries if countries are able to adapt to climate change the long term effects of temperature variations should be lower than the contemporaneous effect nevertheless my results on the long term effects analysis do not support this hypothesis suggesting no or very low adaptation moreover the negative effect of temperature is persistent and cumulative through several years after the temperature shock concerning precipitation variation effects they are found mainly at the product level with the positive effect dominating for the affected products

assessing the variability of inflation although there has been much argument over the impact of variable inflation rates upon economic performance there has been surprisingly little attempt to define the term variability of inflation carefully or to test proposed hypotheses connecting variability and the level of inflation precise definitions are given in the paper and a model is constructed showing that the level variability hypothesis may be formulated in terms of the presence of heteroscedasticity in a regression model this theoretical model is used to criticize existing studies while an empirical study with australian data illustrates the application of the approach

money and the dispersion of relative prices a price dispersion equation is tested with data from the german hyperinflation the equation is derived from a version of lucas s and barro s partial information localized market models in this extension different excess demand elasticities across commodities imply a testable dispersion equation in which the explanatory variable is the magnitude of the unperceived money growth in order to test this hypothesis a price dispersion series is constructed and a measure of the unperceived part of money growth is estimated the model receives support from the empirical analysis although it is evident that unincluded variables have important effects on price dispersion

multiple faces of preferential market access their causes and consequences this paper suggests an integrated approach to study selection into and consequences of five modes of preferential economic integration agreements peias goods trade agreements gtas services trade agreements stas double taxation treaties dtts bilateral investment treaties bits and currency unions as well as currency pegs cuas a detailed descriptive analysis reveals typical integration patterns with dtts and bits often being first steps towards deeper integration we consider the effects of peias on bilateral goods trade services trade and fdi and provide conclusive evidence that single and combined peias are associated with positive effects not only on single outcome but typically on all outcomes investment liberalization through dtts and bits seems to be particularly beneficial since concluding them alone or in any combination with other agreements encourages goods trade even more than the liberalization of goods trade per se peter egger and georg wamser

are rta agreements with environmental provisions reducing emissions article i nfo this paper investigates whether rtas with environmental provisions affect relative and absolute pollution levels in order to do so the determinants of carbon dioxide emissions convergence are estimated for a cross section of 182 countries over the period 1980 to 2008 a propensity score matching approach is com bined with difference in differences techniques to effectively isolate the effect of the regional trade agree ment rta variable the usual controls for scale composition and technique effects are added to the estimated model and the endogeneity of income and trade variables is modeled using instruments the main results indicate that the co2 emissions of the pairs of countries that belong to an rta with environmen tal provisions tend to converge and are lower in absolute terms whereas this is not the case for rtas without environmental provisions as regards specific agreements we find that emissions converge more rapidly for nafta than for eu 27 and euro med countries we find consistent evidence that only rtas with environ mental harmonization policies affect relative and absolute pollution levels

rtas proliferation and trade diversion effects evidence of the spaghetti bowl phenomenon this paper investigates the trade diversion effects of regional trade agreements rtas so called spaghetti bowl phenomenon sbp in multilateral trade the sbp is due to the proliferation of rtas thus we investigate the relationship between the number of rtas concluded by a country and the additional trade value attributed to an rta the main finding reveals a negative trade effect between them confirming the existence of sbp multilateral trade however results could not conclude evidence of a negative effect of overlapping rtas involving the existence of sbp within north north north south or south south trade but the additional trade value attributed to an rta concluded with eu countries or us seems to confirm significantly a trade diversion effect because of the number of rtas signed by these countries

empirical analysis of macroeconomic time series var and structural models abstract var and structural econometric models have complementary roles in the modelling of macroeconomic time series a constant parameter var provided it is statistically well specified constitutes a valid basis for testing hypotheses of dynamic specification exogeneity and a priori structure thus facilitating model evaluation as well as suggesting a potentially efficient model development strategy deterministic e g trends and regime shifts and stochastic e g integrated variables non stationarities are analysable within this framework and the johansen maximum likelihood procedure for cointegrated systems is used in an analysis of the determination of earnings prices productivity and unemployment in the u k

assessing the impact of unilateral trade policies eba and agoa on african beneficiaries exports using matching econometrics the existing literature studying the impact of non reciprocal preferential trade agreements nrptas assumes implicitly nrptas are non randomly assigned without showing the evidence of that using a matching methodology this paper investigates whether the african growth and opportunity act agoa and the everything but arms eba unilateral trade concessions have had an impact and in what magnitude on the exports of african beneficiary countries in the light of the evidence of the non random nature endogeneity of nrptas methodologically previous studies using the matching procedure focused on bi or multilateral trade agreements our work focuses on nrptas that depend only on donors conditions accordingly we show that for nrptas gravity covariates cannot be used for the matching procedure we propose to use political variables as determinants for obtaining non reciprocal trade preferences in order to address the endogenous nature of nrpta assignment our main results confirm that a country becomes eligible for a nrpta only when it meets certain conditions defined by their donors such as political stability and economic regulation for agoa and freedom of expression and human development for eba results also show that both agoa and eba policies have had a positive impact on african beneficiary countries exports to nrpta s providers even if the magnitude impact of eba is significantly lower than that of agoa

are regional trading arrangements trade creating an application of extreme bounds analysis in this study we use extreme bounds analysis to test the robustness of the hypothesis that regional trading arrangements rtas are trade creating extreme bounds analysis provides a more rigorous test of specification uncertainty than traditional econometric theory by incorporating prior information and using a systematic approach to testing the fragility of coefficient estimates the results show that the trade creation effect of most rtas is fragile using a least squares estimator where all weight is attached to the sampling distribution eight or more of the twelve rtas considered are found to be trade creating when the relative weight in the estimation is shifted from the sampling to the prior distribution the number of rtas that are trade creating falls to six at the 95 percent likelihood ellipsoid moreover when we specify that not all rtas are trade creating four rtas increase trade at the 95 percent likelihood ellipsoid at the extreme bounds when all weight is attached to the prior distribution none of the rtas are found to be trade creating as a result we conclude that the pervasive trade creation effect found in the literature reflects not the information content of the data but rather the unacknowledged beliefs of the researchers

the distribution of price changes in oligopoly econometric analysis of the skew of price change distributions for an eighty industry sample over an eleven year period indicates that the distributions are less skewed in times of rapidly changing prices in concentrated oligopolies and in markets with little product heterogeneity the results provide evidence of less price staggering and greater pricing coordination by firms in times of high inflation and in oligopolistic markets respectively tight oligopolies also appear to have more symmetric distributions when prices are falling than when they are rising suggesting that price decreases are more readily followed than increases copyright 1993 by blackwell publishing ltd

choosing the open sea the cost to the uk of staying out of the euro abstract in this paper we provide an estimate of the trade flows that there would have been between the uk and its main trading partners if the uk had joined the euro as an alternative approach to the standard log linear gravity equation we employ the synthetic control method we show that the aggregate trade flows between britain and eurozone members would have been 16 higher if the uk had adopted the euro we also provide an estimate of the hypothetical euro s effect on trade flows between the uk and non euro countries our results suggest that the adoption of the european currency would also have led to a substantial increase in british trade flows with non euro members finally we provide a new estimate of the euro s trade impact for euro members our results suggest that the adoption of the single currency led to an increase in intra european trade flows of between 19 and 55

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

relative price variability and inflation regression studies have established that there tend to be convex nonsymmetric relationships between relative price variability and the inflation rate unanticipated inflation and the change in the inflation rate this paper shows that such regression results follow as definitional artifacts for a simple but quite general stochastic model of price changes the analysis is based on the fact that the definitions of relative price variability the inflation rate unanticipated inflation and the change in the inflation rate imply a particular structure for the covariances among these variables the structure of these covariances has implications for the regression coefficients copyright 1991 by ohio state university press

estimating the effects of kyoto on bilateral trade flows using matching econometrics many kyoto countries fear a loss of competitiveness due to unilateral climate policy efforts policymakers therefore call for carbon related border tax adjustments with this paper we attempt to estimate the treatment effect of kyoto commitment on bilateral export flows using regression adjusted differences in differences matching techniques the gravity and international environmental agreement formation literatures provide guidelines for the choice of matching variables we find that kyoto countries exports are reduced by 13 to 14 per cent due to kyoto commitment trade effects are largest in energy intensive homogeneous industries such as iron and steel non ferrous metals organic and inorganic chemicals but also in machinery and equipment

general equilibrium treatment effects a study of tuition policy this paper defines and estimates general equilibrium treatment effects the conventional approach in the literature on treatment effects ignores interactions among individuals induced by the policy interventions being studied focusing on the impact of tuition policy and using estimates from our dynamic overlapping generations general equilibrium model of capital and human capital formation we find that general equilibrium impacts of tuition on college enrollment are an order of magnitude smaller than those reported in the literature on microeconomic treatment effects the assumptions used to justify the late parameter in a partial equilibrium setting do not hold in a general equilibrium setting policy changes induce two way flows we extend the late concept to a general equilibrium setting we present a more comprehensive evaluation to program evaluation by considering both the tax and benefit consequences of the program being evaluated and placing the analysis in a market setting this abstract was borrowed from another version of this item

monetary economic myth and econometric reality few of the main macro economic forecasting systems can produce sensible forecasts without the tender loving care of their proprietors many econometric equations in com mon use show significant deterioration in the accuracy with which they characterise data as time passes and many economists are sceptical about empirical evidence feeling it lacks credibility monetary relationships have the dubious distinction of being among the leaders in this field as witnessed by the very large mispredictions of m1 models in the usa over what is now known as the missing money period 1973 76 as well as during the recent great velocity decline 1979 82 in the uk models of m1 and m3 demand experienced large structural breaks following the competition and credit control regu lation changes and the move to floating exchange rates perhaps it is no surprise that goodhart s law should have been formulated with respect to money demand equations

inflation and unemployment the world economy today is vastly different from the 1930s when seymour harris the chairman of this meeting infected me with his boundless enthusiasm for economics and his steadfast confidence in its capacity for good works economics is very different too both the science and its subject have changed and for the better since world war ii but there are some notable constants unemployment and inflation still preoccupy and perplex economists statesmen journalists housewives and everyone else the connection between them is the principal domestic economic burden of presidents and prime ministers and the major area of controversy and ignorance in macroeconomics i have chosen to review economic thought on this topic on this occasion partly because of its inevitable timeliness partly because of a personal interest reaching back to my first published work in 1941

simultaneously modeling the supply of weeks and hours of work among female household heads this paper explores the differential nature of labor supply decisions regarding weeks of work per year and hours of work per week among female household heads a model of labor supply that separates the weeks hours decision is presented and estimated allowing for simultaneity in the weeks hours decision as well as for the presence of either fixed costs or weeks and hours constraints the results indicate that not only are weeks and hours decisions separate from the labormarket participation decision but they are also quite different from each other although they appear to be simultaneously determined

robustness of the relationship between price variability and inflation for us manufacturing we study the relationship between relative price variability and inflation in two different ways we first look at product class census unit values for five time periods between 1958 and 1982 and find evidence of a positive relationship between variability and inflation then we directly update the vining and elwertowski 1976 study for the period 1974 91 using individual commodity series from the bureau of labor statistics we conclude by discussing differences across industries in price stickiness

credit constraints and the labour supply of immigrant families in canada the hours of work decisions in immigrant and nonimmigrant families are compared using an intertemporal labor supply model estimated over data from the 1981 and 1991 census of canada surveys the family investment hypothesis is evaluated the hypothesis states that the immigrant family is unable to borrow in the first years after migration and that the immigrant wife responds by working longer hours so as to support family consumption and her husband s labor market adjustment the empirical evidence in general supports the hypothesis since credit constraints are found to significantly distort the labor supply decisions of recently arrived immigrant families

the dispersion of relative commodity prices under very rapid inflation abstract the hypothesis that inflation is not neutral with respect to relative commodity prices has recently received a great deal of attention in this paper the recent experience of argentina a country suffering from a very high rate of inflation is considered it is found that the increase in relative price variability which is associated with higher rates of inflation is caused mainly by surprises or unanticipated changes in the inflation rate and that fully expected inflation appears to have less or no relative price effects an additional result indicates that increased variability of relative commodity prices have effects on financial portfolio composition reducing the holdings of real cash balances

life cycle labor supply with human capital accumulation a dynamic model of labor supply under uncertainty with endogenous human capital accumulation is developed and estimated using 1968 81 panel study of income dynamics male panel data given a learning by doing technology for human capital investment and a translog utility function structural parameters for preferences and technology are estimated from the orthogonality conditions implied by the euler equations assuming rational expectations the parameter estimates conform to economic theory simulations of the model suggest that the intertemporal labor supply elasticity with endogenous wages will rise over the lifecycle producing different policy implications than typical models with exogenous wages and constant intertemporal elasticities copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

on inflation and real price variability this paper studies the consequences of costly price adjustments for the variability of real prices accompanying inflation for constant elasticity demand and cost of production it is shown that a higher demand a lower cost of production or a lower cost of price adjustment leads to less intertemporal variability of real prices if the marginal cost of production does not increase too fast then the average real price is less than the real price that would prevail in the absence of inflation additionally a higher demand a lower cost of production or a lower cost of price adjustment leads to a higher level of real prices

trade in services and regional trade agreements do negotiations on services have to be specific trade in services has been on a substantial positive trend since the last decades and the number of regional trade agreements rta in force has increased regularly overtime however negotiations on services remain hesitant even at the bilateral level to evaluate the impact of rtas on trade in services a general classi cation as balassa s classi cation is not exactly appropriate to go through the 211 rtas noti ed to the wto permits a data analysis and then to sort rtas according to the own level of liberalization in services of every agreement i estimate a gravity equation using panel data covering the period 1999 2007 adding time varying dummies country and time

economic integration among developed developing and centrally planned economies a comparative analysis we examine six integration schemes and decompose their ability to increase inter member trade into environmental policy and system effects environmental factors caused the greatest variation in trade creation with inter member distance the most important environmental variable the cacm and efta have followed more effective integration policies than the eec lafta and the andean pact although integration can thus benefit developed and developing countries alike for some such as those in latin america inter member distances severely limit its effectiveness while the combination of policy and system has kept the cmea fromrr achieving its full potential for increasing inter member trade its effectiveness does not differ from that of unions among market economies

intertemporal substitution in labor supply evidence from micro data the sensitivity of the supply of labor to intertemporal variation in the wage is an important issue in macroeconomics the analysis of social security and pensions and the study of life cycle patterns of work this paper explores two approaches to the measurement of intertemporal substitution that have appeared in the literature the first approach is to use consumption to control for wealth and unobserved expectations about future wages in the labor supply equation the second approach is to estimate a first difference equation for hours in which labor supply from the previous period serves as a control for wealth and wage expectations the results indicate that intertemporal substitution elasticity for married men is positive but small

relative prices and inflation new evidence from different inflationary contexts this paper analyses the relationship between inflation and relative price variability in the direction of the latter in two countries with very different inflationary experiences argentina and spain to address this objective using disaggregated price indexes the wholesale price index for argentina and the consumer price index for spain we delimitate different inflationary regimes and compute a set of regressions for each country our results suggest evidence in favour of the non neutrality of inflation mostly in hyperinflation periods and do not support either the menu costs or the signal extraction approaches we also detect significant structural changes in the relationship depending on the inflationary regime

testing intertemporal substitution implicit contracts and hours restriction models of the labor market using micro data we present new tests of three theories of the labor market intertemporal substitution hours restrictions and implicit contracts the intertemporal substitution test we implement is an exclusion test robust to many specification errors and we consistently reject this model we model hours restrictions as part of an endogenous switching model we compare the implicit probit equation to an unrestricted probit equation for unemployment and reject the hours restriction model for the implicit contracts model we estimate non separable within period labor supply and consumption equations we test a cross equation restriction of the model and cannot reject the implicit contracts model jel e30 j22 j60

trade benefits under the eec generalized system of preferences the purpose of the paper is to test for the existence of a statistically significant effect of the eec generalized system of preferences on actual trade flows between developing countries and the eec using a gravity type model we estimate the gross trade creation effect of the eec generalized system of preferences on the eec imports from 10 major developing countries estimation on a yearly basis for the period 1967 1978 indicates the presence of a statistically significant effect it would appear that gross trade creation amounted to about s2 billion for these 10 countries in 1978 in addition to these calculations the paper reviews the eec generalized system of preferences in detail and offers comments on its future impact on exports from developing countries

the effects of male and female labor supply on commodity demands we examine the effects of male and female labor supply on household demands and present a simple and robust test for the separability of commodity demands from labor supply using data on individual households from six years of the uk fes we estimate a demand system for seven goods which includes hours and participation dummies as conditioning variables allowance is made for the possible endogeneity of these conditioning labor supply variables we find that separability is rejected furthermore we present evidence that ignoring the effects of labor supply leads to bias in the parameter estimates

migration and development dissecting the anatomy of the mobility transition abstract emigration first increases and then decreases as a country experiences economic development this inverted u shaped cross sectional relationship between emigration and development was first hypothesized by zelinsky s theory of the mobility transition although several mechanisms have been proposed to explain the upward segment of the curve the most common being the existence of financial constraints they have not been examined in a systematic way in this paper we propose two decomposition methods to disentangle the main drivers of the mobility transition curve to oecd destination countries our simple decompositions shed light on the role of both microeconomic drivers i e financial incentives and constraints and macroeconomic drivers as well as the skill composition of the population our double decomposition further distinguishes between migration aspirations and realization rates by education level overall we provide consistent evidence that the role of financial constraints while relevant for the poorest countries is limited rather a large fraction of the increasing segment is explained by the skill composition and by macroeconomic drivers i e by factors that do not change in the short run

inflation fixed cost of price adjustment and measurement of relative price variability theory and evidence in an interesting paper julio rotemberg 1983 extends the works of eitan sheshinski and yoram weiss 1977 and michael mussa 1981 to examine the aggregate consequences of monetary growth in an economy in which sellers incur a fixed cost of price adjustment the fixed cost prevents a continual adjustment of individual prices so each seller keeps his price constant in periods of discrete length increasing his price in discrete jumps at the end of these periods a central feature of the inflationary process is therefore that relative prices become dispersed around their means and the theory predicts that even a fully anticipated inflation increases the variability of relative prices the empirical evidence on this point does however appear to be mixed on the one hand richard parks 1978 and stanley fischer 1981a b 1982 conclude that anticipated inflation does increase relative price variability which fischer interprets as providing empirical support for the theory on the other hand mario blejer 1981 1983 and blejer and leonardo leiderman 1982 find that anticipated inflation has no effect or only a very weak effect on relative price variability which makes john taylor 1981 doubt the quantitative significance of the theory 2 this paper uses rotemberg s theoretical framework to demonstrate that the proxy for relative price variability adopted in the empirical literature does not properly capture the relative price variability that is caused by a fixed cost of price adjustment the methodology of the above cited studies is therefore not appropriate for evaluating the empirical relevance of the fixed cost theory and the divergence of their results is not surprising specifically the proxy which consists of the variance of the rates of price change between successive observations does not always increase with the anticipated inflation even with disaggregate data 3 the proxy decreases with the anticipated inflation in approximately half of any interval of inflation rates for which a seller adjusts his price no more than a given number of times between successive observations moreover the relationship between the anticipated inflation and the proxy depends on such extraneous factors as the timing of the observations a change in the timing may change a positive relationship between the anticipated inflation and the proxy to a negative one and vice versa the paper also proposes alternative more satisfactory measures of relative price variability and provides empirical support for the theoretical conclusions

do sanitary phytosanitary and quality related standards affect international trade evidence from chilean fruit exports summary increasing awareness of food safety issues has led to intensive use of sanitary phytosanitary and quality related regulations and standards imposing a burden on exporting countries worldwide this study assesses the impact of such regulations and standards estimating a gravity model for chilean fresh fruit exports that incorporates a stringency perception index that comprises different dimensions of trade requirements our results suggest that an increase in stringency has a negative and substantial effect on exported volumes and the reduction is higher if stringency increases in developed countries results also showed that different dimensions have different effects on trade

mergers and acquisitions trade a global value chain analysis the present paper deals with how the insertion in international trade and global value chains gvcs of countries affects their capacity of attracting foreign mergers and acquisitions m as to this end we combine data for bilateral m as and trade in value added for the period 2001 15 and estimate an augmented gravity equation results indicate that trade openness per se does not favour m as nevertheless bilateral free trade agreements heterogeneity of destinations sources for exports imports of intermediate and final goods and position and participation in global value chains are relevant for explaining bilateral m as moreover their role is significantly different depending on the level of development of the home and host countries

do trade agreements stimulate international trade differently evidence from 296 trade agreements in a seminal article rose 2004 found that the assumed positive impact of the wto on international trade was questionable this finding has been scrutinised and modified in subsequent research using different data sets econometric methods and separating the wto from other forms of trade agreements a key characteristic of the subsequent literature is the rather simplistic way in which trade agreements are treated whereby all trade agreements are lumped together trade agreements come however in many different forms and shapes this study addresses these differences in trade agreements using a unique database of 296 trade agreements we distinguish 17 trade related policy domains and indicate whether the agreements contain legally enforceable commitments this extensive and novel taxonomy of trade agreements enables us to allow for the possible heterogeneity of the impact of trade agreements on international trade using a gravity model we find that trade agreement heterogeneity indeed matters for international trade and that countries experience significant trade increases due to comprehensive trade agreements even if not all participants are in the wto

economic effects of currency unions we develop a new instrumental variable iv approach to estimate the effects of different exchange rate regimes on bilateral outcomes the basic idea is that the characteristics of the exchange rate between two countries are partially related to the independent decisions of these countries to peg explicitly or de facto to a third currency notably that of a main anchor this component of the exchange rate regime can be used as an iv in regressions of bilateral outcomes we apply the methodology to study the economic effects of currency unions the likelihood that two countries independently adopt the currency of the same anchor country is used as an instrument for whether they share a common currency we find that sharing a common currency enhances trade increases price comovements and decreases the comovement of real gross domestic product shocks

has fiscal policy helped stabilize the postwar u s economy abstract in this paper i consider whether postwar fiscal policy has helped stabilize the u s economy i do this by adding to the stochastic growth model fiscal policy feedback rules estimated from postwar data these rules allow fiscal policies to respond to current and lagged output and labor hours i use the estimated policy rules to see if postwar fiscal policy reduces output volatility and or lengthens expansions and shortens recessions i find that fiscal policy in general provides little stability on either count i also find that the endogenous feedback links by themselves can provide some stabilization

currency unions and trade how large is the treatment effect currency unions and trade what can the data say 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 torsten persson i have always maintained that the measured effect of a single currency on trade appears implausibly large but i am not convinced by torsten persson s diagnosis and proposed solution i apply a variety of estimation techniques to a new larger data set where many more instances of currency union creation and abandonment make it possible to rely on time series as well as cross sectional evidence the results are similar to my earlier ones the effect of a single currency on trade is large andrew rose

relative price and inflation variability in a simple consumer search model there is a large empirical literature on the effect of aggregate inflation on both price level dispersion relative price variability rpv and inflation rate dispersion relative inflation variability riv across goods or locations early empirical work of riv has an explicit theoretical foundation in signal extraction models however recent empirical work on rpv has produced results inconsistent with signal extraction models in particular while riv is increasing in the absolute value of inflation shocks rpv is a negative monotonic function of inflation shocks we show that consumer search theory offers a potential explanation for these apparently contradictory observations

relative price variability and inflation a disaggregated analysis relative price variability has been studied at the cross sectional intermarket level this paper addresses the equally important phenomenon of intramarket variability the dispersion of commodity price movements around the industry average using quarterly price data for 80 disaggregated commodity groups in the united kingdom from 1974 to 1984 the paper investigates the determinants of intramarket price variability and replicates some previous crosssectional tests for the united kingdom intermarket price variability is found to be positively related to inflation which confirms previous results for the united states and other countries intramarket variability is found to be positively related to the average market rate of price change but the strength of this relationship appears to be inversely related to the level of industry concentration these results generally support the propositions and findings reported by stigler and kindahl

inflation and relative price variability in the open economy this paper explores the determination of relative price variability in a small open economy operating under a fixed exchange rate a central ingredient of the model presented is the distinction made between traded and non traded goods this distinction leads to a decomposition of total variability into three components the variabilities within each set of goods and between the two sets the analysis also emphasizes the effects of expected versus unexpected inflation on the variability of relative prices the model is tested using annual data for mexico covering the 1951 76 period

intercountry differences in the relationship between relative price variability and average prices this paper provides new evidence on the relationship between relative price variability and inflation the model uses a consistently defined data set for nine european countries it benefits from the inclusion and testing of the effects of macroeconomic variables and the incorporation into the measures of inflation and dispersion adjustments for timeliness appropriate formulas and proximity the general findings of an effect on relative price variability by the macroeconomic environment and negative coefficients on unexpected inflation are supported by their occurrence in models estimated by seemingly unrelated regression and a robust systems estimator

modelling relative price variability and aggregate inflation in the united kingdom the relationship between relative price variability and aggregate inflation in the uk is used to illustrate a number of issues in econometric modelling methodology the rigorous evaluation of models especially testing for congruence and encompassing is emphasized the valuable role of recursive estimation methods in assessing model adequacy is demonstrated attention is drawn to the potential limitations of single equation and univariate analysis of time series data and a recently proposed modelling strategy for analyzing nonstationary variables with cointegrating relationships based on sequential reductions of a congruent var is applied to a small system involving inflation and relative price variability

testing whether unemployment represents intertemporal labour supply behaviour in the lucas rapping 1969 model of the labour market fluctuations in unemployment represent individuals optimally adjusting their labour supply behaviour in response to fluctuations in wage rates over the business cycle in this paper i propose and implement a misspecification test of the lucas rapping treatment of unemployment as labour supply behaviour using panel data this test extends previous such work with micro data by simultaneously allowing for intertemporal substitution uncertainty and endogenous unemployment using the standard specification of intertemporal labour supply behaviour i find strong evidence against this interpretation of unemployment there are two possible interpretations of the test results the first is that it is necessary to turn to alternative models of the labour market in which unemployed workers are off a supply function the second is that the test results indicate the necessity of moving to more complex models of intertemporal substitution however given current econometric techniques and data sets these alternative models of intertemporal substitution will be extremely difficult to test

measuring the impact of china s export growth on its asian neighbours the rise of china as an economic power has led to concern in many countries especially among asian countries that this development poses a serious threat to their own economic performance and in particular their ability to export the empirical support for this view remains inconsistent however with mixed evidence for the view that chinese exports has harmed or helped exports by other asian economies and which countries are more or less affected one explanation for these inconsistencies might include the various biases that follow from the use of a gravity model that is specified in an a theoretical manner in this paper we study the effect of the chinese exports growth on those by other asian countries using the empirical framework outlined by baldwin and taglioni 2006 the disadvantage of this approach is that we capture the relative effect rather than its direction that is when using the theoretically robust gravity model we are able to identify which countries are more or less harmed by chinese exports and not whether the effect is positive or negative to identify that we use instead trade on parts and components and final goods taken together we evidence of a positive relation between chinese and its asian neighbours exports with countries with greater endowments of human capital and capital labour ratio benefiting most from this growth

trade in polarized america the border effect between red states and blue states political and cultural polarization in the united states is widely discussed but does it relate to any economic disconnection among states we estimate the border effect between red and blue states using the gravity equation with a nonlinear generalized method of moments estimator to simultaneously overcome the problems associated with endogeneity cross state price differences and zero trade flow the border effect is robustly confirmed for the 2000s while not so robustly detected for the 1990s notably in 2007 the border reduces trade between red and blue states to approximately 75 of the trade within each set of states this estimated border effect is much smaller than the united states canada national border effect estimated by anderson and van wincoop 2003 and by feenstra 2002 yet is comparable to the border effect that nitsch and wolf 2009 find for the former west and east germanies approximately loyears after reunification while the border effect in germany after reunification is decreasing the border effect between the red and blue states is emerging we also find the border effect is more significant for consumption rather than intermediate goods the border effect is an important indicator for a potential dismantling of the economic connectivity in the united states jel d72 f10 fi5 r1 i introduction recent u s presidential elections have raised concern about polarization in u s politics and culture namely the united states is divided into two nations the red states we call it the red nation preserving the term state for an individual state and the blue states the blue nation in the red nation culturally and religiously conservative republicans are dominant while in the blue nation liberal democrats are the majority so far the focus of the discussion is the extent of the polarization abramowitz and saunders 2008 fiorina et al 2008 its determinants gelman et al 2010 and its implications on federal policy making glaeser et al 2005 mellow and trubowitz 2005 economic implications have not been largely discussed however the polarization may suggest economic divisions because it is a sign of geographic sorting of people and their preferences this article provides evidence that economic disconnectivity between the red and blue nations emerged in the 2000s we explore 1 whether there is a border effect on interstate trade 2 if the effect exists how large it is and 3 what types of goods are most affected in the context of existing literature and recent u s political and cultural events we then provide possible explanations for our findings this study uses a gravity equation of international trade to examine the effect of the fictional national border between the red and blue nations the methodology was originally applied by mccallum 1995 to estimate the degree of impact of the national border on trade between the united states and canada he finds that intercountry trade is less than 5 of the intracountry trade of canada controlling for other factors following mccallum s 1995 work several studies have proposed methodological improvements we apply an updated estimation method nonlinear generalized method of moments gmm estimator of a gravity equation to examine the border effect between the red and blue nations our analysis finds a statistically and economically significant border effect between the red and blue nations especially in years 2002 and 2007 we examine the border effect in 1993 1997 2002 and 2007 the years in which trade flow data are available from the federal commodity flow survey cfs the border effect is not robustly found in 1993 and 1997 however it is robustly detected in 2002 and 2007 even with additional controls or alternative specifications at the industry level analysis we find that the border effect is significant for consumption goods such as food tobacco and printed products but not for intermediate products i

the direct and relative effects of preferential market access abstract the proliferation of preferential trade agreements has resulted in a complex system of preferences in which market access conditions are often discriminatory in this paper we investigate how market access conditions have evolved between 2000 and 2009 and how this has affected international trade our results show that the proliferation of preferential access has increased bilateral trade not only due to lower tariffs but also because preferential access often resulted in higher preferential margins vis a vis foreign competitors the results also indicate that the evolution of the system of preferences has been disadvantageous for countries that did not actively engage in forming new trade agreements

a gravity model of virtual water trade this work investigates the determinants of virtual water trade vwt ows by means of an estimated gravity model of trade applied to the virtual water embodied in the agricultural goods exchanged across countries in line with the recent literature on the gravity model the paper presents a battery of estimation methods cross section and panel ols and pseudo maximum likelihood with and without two way xed eects the analysis shows that bilateral vwt ows are aected by the classical determinants of trade but also by national water endowments as well as by the level of pressure on water resources these general ndings are robust even though some variation can be observed across the estimation methods and in particular when smaller sub samples of countries such as continents and regional groups are considered this contributes to account for the mixed evidence in the literature on the importance of water endowments for the vwt ows
