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

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

communal land and agricultural productivity this paper quantifies the aggregate impact of communal land tenure ar rangements that prevail in sub saharan africa such tenure regimes limit land transfer ability by prohibiting sales subjecting rented out land to the risk of expropriation and redistributing it to existing farmers in a progressive fashion we use a general equilibrium two sector selection model featuring agents heterogeneous in skills to compute the result ing occupational and operational choices as well as land allocations the quantification of the model is based on policies deduced from ethiopia in the sub saharan african context we find that such policies substantially dampen nominal agricultural relative to non agricultural productivity by 25 real relative agricultural productivity however only falls by 4 since cross sectoral terms of trade adjust strongly with excess agricul tural employment only amounting to some 1 5 percentage points the loss in gdp is small about 2 that serves as a reminder that ostensibly highly distortionary policies need not have substantial bite when individuals strategically adjust to them and equilib rium prices adapt for example the model predicts that at given prices 62 of farmers in an economy such as ethiopia would leave farming if tenure were secured casting land insecurity as a major obstacle yet only 9 would actually switch sectors after price adjustments are factored in

how migration restrictions limit agglomeration and productivity in china china strongly restricts rural urban migration resulting in a well acknowledged surplus of labor in agriculture but migration is also restricted within sectors this paper argues that these intra sector restrictions lead to insufficient agglomeration of economic activity in both the rural industrial and urban sectors with resulting first order losses in gdp for urban areas the paper estimates a city productivity relationship based on city gdp numbers the effects of access educational attainment fdi and public infrastructure on productivity are estimated given these worker productivity is shown to be an inverted u shape function of city employment with the peak point shifting out as industrial composition moves from manufacturing to services as predicted by urban theory as far as we know this is the first paper to actually estimate the relationship between output per worker and city scale for any country the majority of chinese cities are shown to be potentially undersized below the lower bound on the 95 confidence interval about the size where their output per worker peaks the paper calculates the large gains from increased agglomeration in both the rural industrial and urban sectors

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

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

what is the aggregate economic rate of return to foreign aid in recent years academic studies have been converging towards the view that foreign aid promotes aggregate economic growth we employ a simulation approach to i validate the coherence of empirical aid growth studies published since 2008 and ii calculate plausible ranges for the rate of return to aid our results highlight the long run nature of aid financed investments and the importance of channels other than accumulation of physical capital we find the return to aid lies in ranges commonly accepted for public investments and there is little to justify the view that aid has had a significant pernicious effect on productivity

exact consumer s surplus and deadweight loss consumer s surplus is a widely used tool in applied welfare economics both economic theorists and cost benefit analysis often use consumer s surplus despite its somewhat dubious reputation the basic idea is to evaluate the value to a consumer or his willingness to pay for a change in price of a good from say pricep to pricep because price changes affect consumer welfare an evaluation of this effect is often a key input to public policy decisions yet consumer s surplus is probably the most controversial of widely used economic concepts both paul samuelson and ian little conclude that the economics profession would be better off without it it is my feeling of the situation that substantial agreement exists on the correct quantities to be measured the amount the consumer would pay or would need to be paid to be just as well off after the price change as he was before the price change the quantities correspond to john hicks compensating variation measures an alternative measure which takes ex post price change utility as the basis of comparison is hicks equivalent variation the controversy arises in the measurement of these quantities the usual measurement procedure is to use the area to the left of the marshallian market demand curve between two price levels jules dupuit originated this measure of welfare change and alfred marshall and hicks derived appropriate conditions for its use the primary condition for the area to the left of the demand curve to correspond to the compensating variation is to have constant marginal utility of income marshall gave this condition and if it holds the same quantity will be derived as the area to the left of the compensated hicksian demand curve this area to the left of the compensated demand curve is exactly what the compensating variation and equivalent variation measure thus the constant marginal utility of income is a sufficient condition for marshallian consumer s surplus to be equal to hicks consumer s surplus in this case arnold harberger s plea to use the welfare triangle as one half times the product of the price change times the quantity change to measure deadweight loss corresponds to the correct theoretical amount of welfare change in a recent paper robert willig derives bounds for the percentage difference between the correct measure of either the compensating or equivalent variation and the marshallian measure derived form the market demand curve his bounds which depend on the income elasticity of demand for the single good in the region of price change being considered as well as the proportion of the consumer s income spent on the good demonstrate that the marshallian consumer s surplus is often a good approximation to hicks consumer s surplus the fact that the proportion of the consumer s income spent matters as well as the income elasticity was first pointed out by harold hotelling willig contends that the approximation error will be less than the errors involved in estimating the demand curve thus he hopes to remove the need for apology that applied economists often need to give to theorists who remark on the inappropriateness of using marshallian consumer s surplus to measure welfare change however in this paper i show that for the case primarily considered by willig of a single price change which is also the situation in which consumer s surplus is often used in applied work no approximation is necessary professor of economics massachusetts institute of technology and research associate national bureau of economic research i would like to thank peter diamond erwin diewert daniel mcfadden robert merton robert solow hal varian joel yellin and the referees for help and comments research support from the national science foundation is acknowledged the reason that we still have two rather than one of samuelson s six measures of consumer s surplus arises from an index number problem of the correct basis for the welfare comparison i will give both measures but plan to concentrate on the compensating variation

life cycle individual thrift and the wealth of nations this paper provides a review of the theory of the determinants of individual and national thrift that has come to be known as the life cycle hypothesis lch of saving applications to some current policy issues are also discussed part i deals with the state of the art on the eve of the formulation of the lch some 30 years ago part ii sets forth the theoretical foundations of the model in its original formulation and later amendment calling attention to various implications distinctive to it and sometimes counter intuitive it also includes a review of a number of crucial empirical tests both at the individual and the aggregate level part iii reviews some applications of lch to current policy issues though only in sketchy fashion as space constraints prevent fuller discussion this abstract was borrowed from another version of this item

the depressing effect of agricultural institutions on the prewar japanese economy why didn t the japanese miracle take place before world war ii the culprit we identify is a barrier that kept prewar agricultural employment constant using a standard neoclassical two sector growth model we show that the barrier induced sectoral distortion and an ensuring lack of capital accumulation account well for the depressed output level without the barrier japan s prewar gnp per worker would have been at least about a half of that of the united states not about a third as in the data the labor barrier existed because we argue the prewar patriarchy forced the son designated as heir to stay in agriculture

preference based indices with subsidized commodities and income dependent prices abstract the user cost of publicly provided services is sometimes income dependent high income earners pay more a true cost of living index which includes income dependent prices is suggested it is shown that the corresponding laspeyre index does not only exceed the true index but it exceeds it by no less than in the case of no income dependent price

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

productivity growth in u s agriculture a postwar perspective there has been a long standing fascination with productivity trends in u s agriculture in part this stems from the historical importance of agriculture to the economy but it also reflects economists early and continued interest in quantifying the rate of return to society s sizable investment in agricultural r d the sum of government sponsored and private sector r d investment in agriculture is estimated to have been 268 million in 1953 in that year total r d investment in the economy from all sources amounted to 5 1 billion 2 excluding defense and space related r d which accounted for approximately half of the u s total in the early fifties 3 r d expenditures dedicated to agriculture equaled approximately 10 of total u s investment in r d from all sources

changes in sectoral composition associated with economic growth in this paper the author uses dynamic general equilibrium methods to examine the interrelationship between sectoral composition and growth she shows that growth is affected by sectoral composition and vice versa the model is basically a solow model of sustained growth with multiple consumption goods and nonhomothetic preferences each consumption good is produced using different factor intensities the rate of exogenous technological change is different in each sector nonhomotheticity of preferences drives the result that sectoral composition affects growth rates copyright 1997 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

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

do all countries grow alike abstract this paper investigates the driving forces of output change in 77 countries during the period 1970 2000 a flexible modeling strategy is adopted that accounts for i the inefficient use of resources and ii different production technologies across countries the proposed model can identify technical efficiency and input change for each of three endogenously determined regimes membership in these regimes is estimated rather than determined ex ante this framework enables explorations into the determinants of output growth and convergence issues in each regime

appropriate technology and income differences this article studies the relative productivity of skilled to unskilled workers across countries relative productivities are broken down into the human capital embodied in skilled workers and relative physical productivities reflecting production techniques i find that skilled workers from poorer countries embody less human capital and are also relatively less physically productive furthermore results show that production techniques are inappropriate for most low income countries and these countries experience large increases in gdp per capita by increasing the relative physical productivity of skilled to unskilled workers this suggests that there are significant barriers to the adoption of skill complementary technologies

de agriculturalization as a result of productivity growth in agriculture abstract this paper explores the secular decline in the employment share in agriculture as a result of productivity growth in the agricultural sector i study an equation that states that employment share in agriculture is determined by the subsistence constraint and productivity in agriculture given the calibrated value for subsistence level of consumption in agriculture labor productivity in this sector implies a share of employment in agriculture in the model that turns out to be very close to the data for a variety of countries between 1963 and 2005

structural change and cross country growth empirics one of the most striking features of economic growth is the process of structural change whereby the share of agriculture in gdp decreases as countries develop the cross country growth literature typically estimates an aggregate homogeneous production function or convergence regression model that abstracts from this process of structural change this paper investigates the extent to which assumptions about aggregation and homogeneity matter for inferences regarding the nature of technology differences across countries using a unique world bank dataset it estimates production functions for agriculture and manufacturing in a panel of 40 developing and developed countries for the period from 1963 to 1992 it empirically models dimensions of heterogeneity across countries allowing for different choices of technology within both sectors the paper argues that heterogeneity is important within sectors across countries implying that an analysis of aggregate data will not produce useful measures of the nature of the technology or productivity it shows that many of the puzzling elements in aggregate cross country empirics can be explained by inappropriate aggregation across heterogeneous sectors

china s mobility barriers and employment allocations china s hukou system imposes two main barriers to population movements agricultural workers get land to cultivate but are unable to trade it in a frictionless market social transfers education health etc are conditional on holding a local hukou we show that the land policy leads to over employment in agriculture and it is the more important barrier to industrialization effective land tenure guarantees and a perfect competitive rental market would correct this inefficiency the local restrictions on social transfers favour rural enterprises over urban employment with a relatively smaller impact on industrialization

returns to investment in education a global update the author updates compilations of rate of return estimates to investment in education published since 1985 and discusses methodological issues surrounding those estimates some key patterns among the three main levels of education primary education continues to exhibit the highest social profitability in all world regions private returns are considerably higher than social returns because of the public subsidization of education the degree of public subsidy increases with the level of education which is regressive social and private returns at all levels generally decline by the level of a country s per capita income overall the returns to female education are higher than those to male education but at individual levels of education the pattern is more mixed the returns to the academic secondary school track are higher than the vocational track since unit cost of vocational education is much higher and the returns for those who work in the private competitive sector of the economy are higher than in the public noncompetitive sector and the returns in the self employment unregulated sector of the economy are higher than in the dependent employment sector controversies in the literature are discussed in the light of the new evidence the undisputable and universal positive correlation between education and earnings can be interpreted in many ways the causation issue on whether education really affects earnings can be answered only with experimental data generated by randomly exposing different people to various amounts of education given the fact that moral and pragmatic considerations prevent the generation of such pure data researchers have to make do with indirect inferences or natural experiments some have been attempted the author looks at the research on overeducation or surplus schooling the conclusions reinforce earlier patterns they confirm that primary education continues to be the number one investment priority in developing countries they also show that educating females is marginally more profitable than educating males that the academic secondary school curriculum is a better investment than the technical vocational tract and that the returns to education obey the same rules as investment in conventional capital that is they decline as investment is expanded

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

agricultural productivity and the sectoral reallocation of labor in rural india abstract how do shocks to agricultural productivity affect the allocation of labor across sectors of the economy to answer this i use data from rural india to show that exogenous increases in agricultural productivity caused by abnormally high levels of precipitation lead to an increase in the labor share of the non agricultural sector i further show that the non tradable sector expands significantly when agricultural output increases this evidence is consistent with increasing agricultural output causing increased demand for local non tradables which in turn increases the non agricultural labor share

barriers to capital accumulation and aggregate total factor productivity i develop a growth model where a single good can be produced with a traditional and a modern technology the traditional technology features low total factor productivity tfp and a low share of reproducible capital in this framework barriers to capital accumulation affect technology use and therefore aggregate tfp the theory thus connects recent models of factor accumulation and of tfp the model is calibrated by interpreting traditional production as agriculture and nonreproducible capital as land the theory implies that barriers are associated with large agricultural shares as supported by cross country and time series evidence the required tfp differences needed in the model to account for a given income disparity are reduced by 1 2 relative to the standard model that abstracts from technology choice

income taxation labor supply and the theory of income based cost of living indices abstract this paper derives theoretically exact formulas for income and expenditure based cost of living indices that are implied by a model of utility maximization in the presence of taxation and a goods leisure decision the derived income based cost of living indices not only allow for substitutions among goods and leisure as the incentives to consume them change as do the expenditure based indices but also explicitly incorporate the effects of bracket creep and the tax deductibility of leisure into the value of the indices numerical estimates of three income based measures of the cost of living suggest that bracket creep eroded substantially the purchasing power of u s households during the 1970s

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

the food problem and the evolution of international income levels in most poor countries large fractions of land labor and other productive resources are devoted to producing food for subsistence needs we show that a model incorporating the food problem can provide new and useful insights into the evolution of international income levels in particular we find that the food problem can explain why some countries started to realize increases in per capita output more than 250 years later in history than others we also show that the food problem has important implications for growth miracles and the speed at which a country converges to its balanced growth path

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

underinvestment in a profitable technology the case of seasonal migration in bangladesh hunger during pre harvest lean seasons is widespread in the agrarian areas of asia and sub saharan africa we randomly assign an 8 50 incentive to households in rural bangladesh to temporarily out migrate during the lean season the incentive induces 22 of households to send a seasonal migrant their consumption at the origin increases significantly and treated households are 8 10 percentage points more likely to re migrate 1 and 3 years after the incentive is removed these facts can be explained qualitatively by a model in which migration is risky mitigating risk requires individual specific learning and some migrants are sufficiently close to subsistence that failed migration is very costly we document evidence consistent with this model using heterogeneity analysis and additional experimental variation but calibrations with forward looking households that can save up to migrate suggest that it is difficult for the model to quantitatively match the data we conclude with extensions to the model that could provide a better quantitative accounting of the behavior

the wto trade effect this paper reexamines the gatt wto membership efiect on bilateral trade ows using nonparametric methods including pair matching permutation tests and a rosenbaum 2002 sensitivity analysis together these methods provide an estimation framework that is robust to misspeciflcation biases allows general forms of heterogeneous treatment efiects and addresses potential hidden selection biases this is in contrast to most conventional parametric studies on this issue our results suggest large gatt wto trade promoting efiects robust to various restricted matching criteria alternative indicators for gatt wto involvement different matching methodologies non random incidence of positive trade ows and inclusion of multilateral resistance terms

beyond balanced growth balanced growth models are commonly used in macroeconomics because they are consistent with the well known kaldor facts regarding economic growth these models however are inconsistent with one of the most striking regularities of the growth process the massive reallocation of labour from agriculture into manufacturing and services this paper presents a simple model consistent with both the kaldor facts and the dynamics of sectoral labour reallocation

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

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

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

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

the microeconomic foundations of measuring bracket creep and other tax changes we derive a measure of the bracket creep induced inflation tax based on an income compensation function that recognizes that consumers substitute among deductible and nondeductible goods as the incentives to consume the goods change over time the measure of the inflation tax is decomposed into a convenient function of marginal tax rates and the change in expenditures on tax deductible goods relative to nondeductible goods that are required to maintain a fixed level of utility tentative estimates suggest that the inflation tax as a percentage of constant utility income during the 1970s averaged about 1 percent per year

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

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

inequality in landownership the emergence of human capital promoting institutions and the great divergence this paper suggests that inequality in the distribution of landownership adversely affected the emergence of human capital promoting institutions e g public schooling and thus the pace and the nature of the transition from an agricultural to an industrial economy contributing to the emergence of the great divergence in income per capita across countries the prediction of the theory regarding the adverse effect of the concentration of landownership on education expenditure is established empirically based on evidence from the beginning of the 20th century in the u s

anonymity efficiency wages and technological progress although the industrial revolution is often characterized as the culmination of a process of commercialisation the precise nature of such a link remains unclear this paper provides an analysis of one such link the role of commercialisation in raising wages as impersonal labour market transactions replace personalized customary relations in the presence of an aggregate capital externality we show that the resulting shift in relative factor prices will under certain conditions lead to higher capital intensity in the production technology and hence a faster rate of technological progress we provide historical evidence using european data to show that england was among the most urbanized and the highest wage countries at the onset of the industrial revolution the model highlights the effects of changes in the availability of information typical of a modernising country on efficiency wages and technological progress

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

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

structural change and economic growth this paper presents a model in which a country s measured average propensity to save endogenously rises when its economy industrializes the model has agricultural and manufacturing sectors only agriculture uses land if at early dates income per capita is low agricultural consumption is important land is valuable and capital gains on land may constitute most wealth accumulation leaving the country s nipa aps low if exogenous technological progress raises incomes over time engel s law shifts demand to manufactured goods then land s portfolio importance relative to reproducible capital diminishes and the national income and products account saving rate can rise this paper presents a model illustrating that structural change due to the operation of engel s law can systematically affect an economy s measured saving rate according to the model a country s national income and product account average propensity to save will rise naturally if and when technological progress sufficiently lifts its income per capita this suggests a new interpretation of time series evidence while saving rates historically tend to be higher after industrialization than before one cannot automatically infer that changing wealth accumulation behaviour led to modernization rather structural change accompanying growth may have caused the rise in saving rates this paper also warns that international trade could lead to a contrasting pattern in cross sectional data highincome nations might contemporaneously have lower measured saving rates than poor countries recent work by mankiw romer and weil 1992 islam 1995 mankiw 1995 and others investigates long run patterns the analyses assume that each economy has attained or is moving toward a steady state equilibrium as in solow 1956 a country s steady state level of per capita gdp depends on its average propensity to save aps its rate of population growth the efficiency of its production sector etc regression outcomes seem consistent with the solow model s prediction that a higher aps will ceteris paribus lead to a higher level of income per capita the idea is that heterogeneity of exogenous preferences leads to international differences in aps s and in turn to long run differences

the agricultural productivity gap in europe for fifteen european countries over the 1970 2004 period we establish that there is a large and persistent agricultural productivity gap the ratio of labor productivity in non agriculture to that in agriculture correcting for under reporting of selfemployment income in both agriculture and non agriculture significantly reduces the measured agricultural productivity gap for countries with information on years of school and experience at the sector level we also find substantially higher human capital in non agriculture than in agriculture our findings suggest that measured labor productivity differences between agriculture and non agriculture in european countries are not an indicator of resource misallocation but possibly an artifact of mismeasurement of value added and sectoral differences in human capital

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

the impact of direct taxes on the cost of living in this paper we define a cost of living index including direct taxes we show its relationship to the traditional index and demonstrate how nonconsumption costs are properly treated we then define a fixed weight approximation a tax and price index tpi using federal state local and social security tax rates for 1967 85 we construct annual tpi series based on household data we find that inclusion of direct taxes has sizable impacts on the estimated rate of inflation partitioning our household sample we find that recognition of taxes significantly alters inflation rate differentials estimated using consumption prices alone

what drives the global land rush the authors review evidence regarding the size and evolution of the land rush in the wake of the 2007 8 boom in agricultural commodity prices and authors study the determinants of foreign land acquisition for large scale agricultural investment the use of data on bilateral investment relationships to estimate gravity models of transnational land intensive investments confirms the central role of agro ecological potential as a pull factor however this finding contrasts the standard literature insofar as the quality of the destination country s business climate is insignificant and weak tenure security is associated with increased interest for investors to acquire land in the country policy implications are discussed

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

skill complementarity and the dual economy abstract i propose a new explanation for the large productivity gaps between agriculture and nonagriculture observed in developing countries namely that the elasticity of substitution between skilled and unskilled workers is higher in agriculture than in nonagriculture i estimate the elasticities in a cross country data set and use the results to simulate a simple two sector model in which heterogeneous elasticities of substitution affect relative sectoral productivity levels through the allocation of human capital calibrated to match data from the united states the model predicts sizable agricultural productivity gaps in countries where the share of highly educated workers in the labor force is low

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

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

a model of growth and migration this paper contains a model with which the desirability of persistent urbanization can be examined there are two regions city and countryside joint restrictions on the technologies in each region and on preferences over the goods produced in each region are the driving force of migration in equilibrium there is persistent migration from the countryside to the city even though there are externalities in production the competitive equilibrium is pareto optimal summary in fre excerpt

economic structure and factor payments there is a growing body of evidence that the labour payment share in national income varies across countries and over time suggesting that the popular aggregate cobb douglas production function may not capture income share dynamics there remains conflicting evidence on the importance of natural resource rents among low income economies and on estimates of the rate of return to produced capital this paper focuses on the structural differences among countries confirming the importance of the agriculture sector in estimates of labour and land s share of factor income based on 81 countries at diverse levels of economic development in the year 2005 i find that cross country data are best modelled by a ces production function with an elasticity of substitution of 0 8 and that many low income countries have a higher return to capital than the united states

the drivers of structural change the main goal of this paper is to provide an integrated survey of the literature devoted to identifying the drivers of structural change broadly defined as the process of reallocation of economic activity across the three broad sectors agriculture manufacturing and services using the ggdc 10 sector database this paper first presents the empirical facts associated with structural change in different regions of the world that is europe and the usa asia latin america and africa then reviews four determinants of structural change i changes in income ii changes in relative sectoral prices iii changes in input output linkages and iv changes in comparative advantage s via globalization and trade

industrialisation catching up and economic growth a comparative study across the world s capitalist economies various hypotheses are examined seeking to explain inter country convergence at the upper end but divergence at the lower end of the world income rankings a model of disequilibrium growth with sector specific technological progress and spillover is developed and then estimated on two samples of capitalist economies 1960 85 it is found that the degree of disequilibrium between agriculture and industry is greatest in the least developed economies but their rate of labor transfer has been slow technological spillover has stimulated productivity growth in less developed agricultural sectors but not in the industrial sectors of the least developed economies copyright 1991 by royal economic society

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

the impact of education in rural ghana examining household labor allocation and returns on and off the farm most of the human capital literature pertaining to developing countries focuses on the returns to education in either farm work or wage work few studies examine how education affects the allocation of time between these activities this paper estimates the returns to education in farm and off farm work and consequently the role of education in determining the allocation of labor the results from this study show that off farm work has a much higher return to education than does farm work and suggest that this divergence in returns affects the allocation of labor in farm households between farm and off farm work

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

rural urban disparity and sectoral labour allocation in china this study examines china s rural urban segmentation and its causes in the context of economic reforms household survey and aggregate data indicate a v shaped process in which rural urban consumption and income differentials decreased between 1978 and 1985 but then have continually increased to historically high levels this sectoral division is consistent with production function estimates based on provincial data that reveal higher labour productivity in urban state owned industries than in rural industries and agriculture to explain the v shaped change we argue that the precedent of successful rural reforms raised farmers relative earnings but the remaining obstacles to an efficient sectoral allocation of labour have prevented china from eliminating dualism recent financial policies consisting of urban price subsidies and increased investment credits have also had influential distribution effects that are biased against the rural sector

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

how important are dual economy effects for aggregate productivity this paper brings together development accounting techniques and the dual economy model to address the role that factor markets have in creating variation in aggregate total factor productivity tfp development accounting research has shown that much of the variation in income across countries can be attributed to differences in tfp the dual economy model suggests that aggregate productivity is depressed by having too many factors allocated to low productivity work in agriculture data show large differences in marginal products of similar factors within many developing countries offering prima facie evidence of this misallocation using a simple two sector decomposition of the economy this article estimates the role of these misallocations in accounting for the cross country income distribution a key contribution is the ability to bring sector specific data on human and physical capital stocks to the analysis variation across countries in the degree of misallocation is shown to account for 30 40 of the variation in income per capita and up to 80 of the variation in aggregate tfp

using national statistics to increase transparency of large land acquisition evidence from ethiopia the 2007 08 commodity price boom triggered a rush for land in developing countries yet many affected countries lacked the regulatory infrastructure to cope with such demand and reliable data on investors performance this study uses the example of ethiopia to show how simple improvements in administrative data collection can help to address this by i allowing assessment of the productivity of land use and taking measures to increase it ii comparing productivity between large and small farms to identify spillovers and ways to improve these and iii setting in motion a process of continuing improvement implications for global investment in this area are drawn out

the role of trade in structural transformation abstract low agriculture productivity is considered a key obstacle to economic development for many countries international trade in agricultural goods can help overcome this barrier and facilitate structural transformation because it allows countries to import part of their food needs this article quantifies the role of trade in this context through the examples of south korea during the last 50 years and great britain in the 19th century to do the analysis i calibrate and simulate a two sector neoclassical growth model to match the data and perform the policy experiments i find that agricultural imports played a crucial role in the early transformation of great britain while in south korea trade also had a positive impact on its structural transformation but it could have played a much larger role if the country had not introduced agricultural protection policies

education s role in china s structural transformation abstract we explore education s role in improving the allocation of labor between china s agricultural and nonagricultural sectors and measure the portion of china s recent growth attributable to this channel using detailed micro level data and an empirical model that allows for the endogenous selection of education and sector of employment we estimate the relationship between an individual s educational attainment sector and income we find that about 11 of aggregate growth in output per worker from 1978 to 2004 is accounted for by increased education with 9 coming through the labor reallocation channel and 2 attributable to increased within sector human capital

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

the role of the structural transformation in aggregate productivity we investigate the role of sectoral differences in labor productivity in explaining the process of structural transformation the secular reallocation of labor across sectors and the time path of aggregate productivity across countries using a simple model of the structural transformation that is calibrated to the growth experience of the united states we measure sectoral labor productivity differences across countries productivity differences between rich and poor countries are large in agriculture and services and smaller in manufacturing moreover over time productivity gaps have been substantially reduced in agriculture and industry but not nearly as much in services in the model these sectoral productivity patterns generate implications that are broadly consistent with the cross country evidence on the structural transformation aggregate productivity paths and relative prices we show that productivity catch up in industry explains about 50 percent of the gains in aggregate productivity across countries while low relative productivity in services and the lack of catch up explains all the experiences of slowdown stagnation and decline observed across countries

where has all the education gone cross national data show no association between increases in human capital attributable to the rising educational attainment of the labor force and the rate of growth of output per worker this implies that the association of educational capital growth with conventional measures of total factor production is large strongly statistically significant and negative these are on average results derived from imposing a constant coefficient however the development impact of education varied widely across countries and has fallen short of expectations for three possible reasons first the institutional governance environment could have been sufficiently perverse that the accumulation of educational capital lowered economic growth second marginal returns to education could have fallen rapidly as the supply of educated labor expanded while demand remained stagnant third educational quality could have been so low that years of schooling created no human capital the extent and mix of these three phenomena vary from country to country in explaining the actual economic impact of education or the lack thereof

agriculture and aggregation abstract we study the shape of the aggregate production function in the presence of land intensive agriculture the traditional cobb douglas formulation is corrected to include a diversification component the implied tfp differences across countries are larger than what solow residuals suggest

a century long perspective on agricultural development this article strategically surveys the past century s literature on agricultural development we organize the discussion around three grand themes that reveal the richness of agricultural development as an intellectual endeavor first we explore the role of agriculture in the broader development process from a macroeconomic and political economy perspective we then examine the role of technological and institutional change in successful agricultural development finally the focus turns to a microeconomic perspective on agricultural household decision making and the problems of imperfect and missing markets asymmetric information and transactions costs that lead to widespread apparent inefficiency and disequilibrium

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

labour market effects of large scale agricultural investment conceptual considerations and estimated employment effects summary large scale agricultural investments lsais in general and their socio economic implications in particular have been heavily debated in recent years while some claim that lsais are an important catalyst for development in neglected rural areas others caution that they pose a risk to rural communities livelihoods the extent to which lsais provide benefits for local communities is hence still contested this paper sets out to conceptually understand what effects the establishment of a large scale farm has on the rural labor market in low and middle income countries in addition we empirically address the question of whether large scale farming as recorded in the land matrix creates or destroys employment we develop a transition matrix to identify several scenarios based on key determinants of the direct employment creation potential of lsais namely the former land use the crop type and the production model we empirically assess the actual importance of these scenarios and the employment creation to be expected from this sample of lsais based on labor intensities we further look into the net employment effects for land formerly used by smallholder farmers our analysis shows that lsais massively crowd out smallholder farmers which is only partially mitigated through the cultivation of labor intensive crops and the application of contract farming schemes this holds true for all regions targeted by lsais although regional differences are found in terms of magnitude the paper concludes that these effects tend to be large on the local scale i e in the immediate surroundings of the investment site but small in relation to total national employment in agriculture however indirect employment creation related to lsais which is discussed but not empirically addressed in this paper needs to be taken into account to have the full picture

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

education and allocative efficiency household income growth during rural reforms in china this paper studies the contribution of schooling to rural income in china during factor market liberalization between 1986 and 1995 the relaxation of controls permitted farm households to reallocate productive inputs from agriculture to nonagricultural activities it is hypothesized that education facilitates this adjustment panel data from sichuan province suggest that schooling enhanced the ability of farmers to devote labor and capital to nonfarm production given the evidence that less than optimum levels of these inputs were allocated to nonagricultural uses during the transition the expansion of nonfarm activities contributed significantly to household income growth

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

urban rural gaps in the developing world does internal migration offer opportunities this article provides an overview of the growing literature on urban rural gaps in the developing world i begin with recent evidence on the size of the gaps as measured by consumption income and wages and argue that the gaps are real rather than just nominal i then discuss the role of sorting more able workers into urban areas and review an array of recent evidence on outcomes from rural urban migration overall migrants do experience substantial gains on average though smaller than suggested by the cross sectional gaps i conclude that future work should help further explore the frictions in particular information financial and in land markets that hold back rural urban migration and may help explain the persistence of urban rural gaps

malthus to solow a unified growth theory is developed that accounts for the roughly constant living standards displayed by world economies prior to 1800 as well as the growing living standards exhibited by modern industrial economies our theory also explains the industrial revolution which is the transition from an era when per capita incomes are stagnant to one with sustained growth the authors use a standard growth model with several technologies the first denoted the malthus technology requires land labor and reproducible capital as inputs the second denoted the solow technology does not require land the authors show that in the early stages of development only the malthus technology is used and due to population growth living standards are stagnant despite technological progress eventually technological progress causes the solow technology to become profitable and both technologies are employed at this point living standards improve since population growth has less influence on per capita income growth in the limit the economy behaves like a standard solow growth model excerpt
