determinants of trade costs and trade growth accounting between india and the european union during 1995 2010 this study aimed to utilise the micro founded measure of trade cost derived by novy to estimate the relative bilateral trade costs of india with its european union partners the advantage of using such a model is that the trade costs can be derived entirely using observable trade data the results show that indian tariff equivalent with its major eu trading partners has declined by 20 percentage points between 1995 and 2010 with malta and latvia experiencing the greatest decline the study then decomposes the bilateral trade growth to ascertain whether it is an outcome of increased domestic production or reduction in bilateral and multilateral trade barriers novy s model indicates that the decline in relative bilateral trade costs explains the greatest percentage of this trade growth which is partially offset by decline in multilateral resistance terms that has diverted trade away to other trading partners primarily in south and south east asia and north america

no price like home global house prices 1870 2012 how have house prices evolved in the long run this paper presents annual house price indices for 14 advanced economies since 1870 based on extensive data collection we are able to show for the first time that house prices in most industrial economies stayed constant in real terms from the 19th to the mid 20th century but rose sharply in recent decades land prices not construction costs hold the key to understanding the trajectory of house prices in the long run residential land prices have surged in the second half of the 20th century but did not increase meaningfully before we argue that before world war ii dramatic reductions in transport costs expanded the supply of land and suppressed land prices since the mid 20th century comparably large land augmenting reductions in transport costs no longer occurred increased regulations on land use further inhibited the utilization of additional land while rising expenditure shares for housing services increased demand

real exchange rates and time varying trade costs this paper re examines the empirical modeling of purchasing power parity ppp deviations in the presence of commodity market frictions first we show that a specific type of smooth transition models can closely approximate the functional form of the theoretical adjustment mechanism derived by dumas 1992 dynamic equilibrium and the real exchange rate in a spatially separated world review of financial studies 5 2153 180 for the case of constant as well as changing trade costs second we develop for the first time an empirical model of the real exchange rate which allows for changes in the degree of market integration by employing a long span of data on the dollar sterling real exchange rate and a micro founded proxy for trade frictions we provide novel evidence of a significant relationship between the persistence of the real exchange rate and the level of trade costs this finding suggests that both the difficulty of detecting ppp and the extend of rogoff s puzzle vary over time with the degree of trade restrictiveness finally we highlight policy repercussions of our results

comment on trade integration in colombia a dynamic general equilibrium study with new exporter dynamics abstract this paper provides a series of comments aimed mainly at addressing the empirical relevance of the proposed interpretation of the mechanism and partly at considering the possible interaction between the trade and labor market reforms that took place in colombia in the same period in particular it first highlights the stylized facts about colombian exports and exporters that the model aims to theoretically reconcile and i briefly summarize the mechanism proposed in the microeconomic block of the theory next it focuses on two crucial assumptions made in the model it proposes a complementary way of presenting the mechanism and proposes ways to evaluate the empirical relevance on the competing interpretations finally it focuses on the broader economic and institutional background characterizing colombia in the early nineties and highlights the possibility that other reforms taking place in the same years may have interacted with trade liberalization in shaping firms distribution and export dynamics as well as welfare

what separates us sources of resistance to globalization with increasing sophistication economists have been estimating gravity equations for five decades robust evidence shows that borders and distance impede trade by much more than tariffs or transports costs can explain we therefore advocate investigation of other sources of resistance despite the greater difficult involved in measuring and modelling them from our selective review of recent findings a unifying explanation emerges a legacy of historical isolation and conflict forged a world economy in which neither tastes nor information are homogeneously distributed cultural difference and inadequate information manifest themselves most strongly at national borders and over distance

globesity the effects of globalization on obesity and caloric intake abstract we examine the effect of globalization in its economic and social dimensions on obesity and caloric intake namely the so called globesity hypothesis our results suggest a robust association between globalization and both obesity and caloric intake a one standard deviation increase in globalization is associated with a 23 8 percent increase in obese population and a 4 3 percent rise in calorie intake the effect remains statistically significant even after using an instrumental variable strategy to correct for some possible reverse causality and ommited variable bias a lagged structure and corrections for panel standard errors however we find that the primary driver of the globesity phenomenon is the social rather than the economic dimension of globalization and specifically the effect of changes in information flows and social proximity on obesity a one standard deviation increase in social globalization increased the percentage of obese population by 13 7 percent

shirking or productive schmoozing wages and the allocation of time at work this study uses detailed time diaries from household surveys for 1975 and 1981 to examine how changes in the use of time on the job affect earnings among nonunion workers the marginal minute of break time apparently increases earnings but not as much as does the marginal minute of work time among union workers additional time in unscheduled breaks appears to be associated with significantly higher earnings though other break time is not the author concludes that further growth in on the job leisure would reduce productivity that monitoring workers would yield returns to the firm but that entirely eliminating breaks would be counterproductive

the welfare cost of lawlessness evidence from somali piracy in spite of general agreement that establishing the rule of law is central to properly functioning economies little is known about the cost of law and order breakdowns this paper studies a specific context of this by estimating the effect of somali piracy attacks on shipping costs using data on shipping contracts in the dry bulk market to estimate the effect of piracy we look at shipping routes whose shortest path exposes them to piracy and find that the increase in attacks in 2008 led to around an 8 to 12 increase in costs from this we calculate the welfare loss imposed by piracy we estimate that generating around 120 usd million of revenue for somali pirates led to a welfare loss in excess of 630 usd million making piracy an expensive way of making transfers

hedging price volatility using fast transport abstract purchasing goods from distant locations introduces a significant lag between when a product is shipped and when it arrives these transit lags are trade barriers for firms facing volatile demand who must place orders before knowing the resolution of demand uncertainty we provide a model in which airplanes bring producers and consumers together in time fast transport allows firms to respond quickly to favorable demand realizations and to limit the risk of unprofitably large quantities during low demand periods the model predicts that the likelihood and extent to which firms employ air shipments is increasing in the volatility of demand they face decreasing in the air premium they must pay and increasing in the contemporaneous realization of demand we confirm all three conjectures using detailed us import data fast transport thus provides firms with a real option to smooth demand volatility on international markets and we provide simple calculations of that option value this enables us to identify how the option value relates to goods characteristics and to changes in air transport premia associated with technological and policy change including the introduction of jet engines and liberalization of trade in air services

globalisation and the spatial concentration of production new trade theory models predict that freer trade increases the spatial concentration of industrial production across countries while nations with large home markets and central geographical location become increasingly attractive business locations small peripheral countries gradually deindustrialize using data for 26 industries 20 oecd countries and 20 years we investigate the empirical validity of this claim separating out the role of home market size from geographical factors and using various panel methods we find robust evidence in line with theory freer trade has indeed magnified the importance of domestic demand and geographical location for the pattern of industrial production across the globeand has therefore exacerbated spatial disparities

rising trade costs agglomeration and trade with endogenous transaction costs while transport costs have fallen the empirical evidence also points at rising total trade costs in a model of industry location with endogenous transaction costs that seeks to replicate features from the machinery industry we show how and under which conditions a decline in transport costs can lead to an increase in the total cost of trade the subtle relationship between endogenous transport costs and the sensitivity of trade

labour and environmental standards the lemons problem in international trade policy environmental and labour standards have become an important international trade issue this article examines and ranks alternative trade policy responses available to an importing country with concerns over such standards while a full import embargo may sometimes be preferable to allowing unrestricted access to unlabeled noconforming imports a partial embargo that allows imports which demonstrably conform to the standard is always a better policy and labeling solutions which separate conforming and non conforming imports are typically better still consequently full import embargoes based on non conformity with labour or environmental standards are poor policy choices and should generally remain prohibited by wto rules

shipping the good horses out this paper formalizes the alchian allen 1964 theorem within a vertically differentiated goods general equilibrium model in contrast to the existing literature equilibrium prices depends on the transportation cost it shows that the eect of a xed transportation cost regardless of quality tilts the importing region s demand towards the consumption of higher quality goods the model extends the alchian allen theorem by showing that the strength of this eect depends on the importing region s endowment specically if the importing region is endowed with the imported goods of similar quality mix the eect is even stronger we also show that the importing region s market size and preferences matter to the strength of the eect using auction data of australian thoroughbred yearlings we conrm that better horses are shipped out further furthermore consistent with the model s prediction the strength of the alchian allen eect depends on the endowment of the importing regions

pride and prejudice using ethnic sounding names and inter ethnic marriages to identify labour market discrimination labour markets discriminate against workers with particular ethnic sounding names we use non random sorting into interethnic marriage and salient differences between sephardic and ashkenazi surnames to evaluate the causal impact of sephardic affiliation on wages using the 1995 israeli census we estimate the effect of a sephardic sounding surname on wages we first compare the wages of israeli jewish males born to sephardic fathers and ashkenazi mothers sa who are more likely to carry a sephardic surname with the wages of israeli jewish males born to ashkenazi fathers and sephardic mothers as we find that israeli labor markets discriminate based on perceived ethnicity sa workers earn significantly less than their as counterparts we then exploit the custom of women to adopt their husbands surnames to disentangle actual ethnicity from the ethnicity perceived by the market consistent with ethnic discrimination based on surnames we find that it is father in law s ethnicity rather than father s ethnicity that shapes female wage rates finally we find that labor markets discriminate based on surname only when those names provide additional information about ethnicity when ethnicity can be discerned from skin tone surnames do not provide additional explanatory power with respect to wages

commodity storage and the market effects of biofuel policies the author 2016 legislation passed in 2007 by the u s congress increased by about 1 3 billion bushels the net amount of corn required to be processed annually into ethanol for motor fuel use we estimate that corn prices were about 30 higher from 2006 to 2014 than they would have been without this demand increase we develop a partially identified structural vector autoregression model our identification strategy is unique in the literature because it enables us to estimate the effects of transitory shocks such as weather separately from the effects of persistent shocks such as the increased ethanol mandate moreover by only partially identifying our model we show how to generate robust conclusions without strong identifying assumptions

cabotage sabotage the curious case of the jones act abstract this paper examines the economic implications of the jones act which restricts domestic waterborne shipments to american vessels since the passage of this cabotage law a century ago a plausibly exogenous rise in foreign competition has contributed to the closure of most american shipyards and to a decline in american built ships thus the jones act requirements have become more onerous over time the results show that domestic shipments are less likely to be transported via water than imports of the same good into the same state exploiting the decline in jones act eligible vessels over time additional results show that this cabotage law has disproportionately decreased domestic water trade especially in coastal states these findings support common but to date unverified claims that the jones act impedes domestic trade

the gatt in historical perspective the transformation of the general agreement on tariffs and trade gatt into the world trade organization wto on january 1 1995 provides an opportune moment to take stock of the gatt s achievements and shortcomings alongside those of its 50 year old sister international institutions set up at bretton woods it is temptingly easy to attribute the astounding postwar economic expansion particularly when set against the turbulent interwar period when multilateral efforts to contain protectionist pressures failed miserably to the economic policies embodied in the gatt and to the initial stability provided by the bretton woods institutions yet a closer look at precisely what the gatt accomplished in its first decade suggests that trade liberalization under its auspices alone is far from sufficient to explain the postwar economic boom

what goes around comes around export enhancing effects of import tariff reductions abstract in international trade transportation requires a round trip for which a transport firm has to commit to shipping capacity that is sufficient to meet the maximum shipping volume this may cause the backhaul problem trade theory suggests that facing the problem transport firms with market power adjust their freight rates strategically when import tariffs change as a consequence a country reducing its import tariffs may experience an increase in exports as well as imports using worldwide data covering 1995 2007 we find evidence that supports these predictions a 1 reduction in an importer s tariffs increases the import freight rates by around 0 8 decreases the export freight rates by around 1 1 and increases the export quantity by 0 6 to 1 these findings indicate a new mechanism through which import tariff reductions lead to export expansions

distance time and specialization lean retailing in general equilibrium transport time increases with distance traveled and time is valuable we show the implications of these facts for global specialization and trade products where timely delivery is important will be produced near the source of final demand where wages will be higher as a result in the model timely delivery is important because it allows retailers to respond to final demand fluctuations without holding costly inventories and timely delivery is possible only from nearby locations using a unique dataset that allows us to measure the retail demand for timely delivery we show that the sources of u s apparel imports have shifted in the way predicted by the model with products for which timeliness matters increasingly imported from nearby countries jel f1 transporting goods and people costs time and money and both transport fees and time in transit generally increase with the distance traveled these facts imply an incentive to economize on distance and the equilibrium effects

trade and climate policies do emissions from international transport matter this paper provides orders of magnitude of the importance of co2 emissions from international transport freight activities under a variety of scenarios regarding trade and climate policies it is based on a stylized multi region multi sector cge model that includes the four modes of international transport air water road and rail and where choices regarding the energy mix and transport mode have been endogeneized a separate decomposition of emission changes into the well known scale composition and technique effects is provided scale effects turn out to be roughly double in international transport than in exports while technique effects are weaker due to less substitutability between energy inputs as a result international transport represents half of the world increase in global emissions when trade liberalization is considered isolately when trade liberalization is coupled with a carbon tax limited to rich countries international transport represents roughly one eigth of the carbon leakage effect

rules of origin and the profitability of trade deflection abstract when a country grants preferential tariffs to another either reciprocally in a free trade agreement fta or unilaterally rules of origin roos are defined to determine whether a product is eligible for preferential treatment roos exist to avoid that exports from third countries enter through the member with the lowest tariff trade deflection however roos distort exporters sourcing decisions and burden them with red tape using a global data set we show that for 86 of all bilateral product level comparisons within ftas trade deflection is not profitable because external tariffs are rather similar and transportation costs are non negligible in the case of unilateral trade preferences extended by rich countries to poor ones that ratio is a striking 98 the pervasive and unconditional use of roos is therefore hard to rationalize

commodity trade and the carry trade a tale of two countries persistent interest rate differentials account for much of the currency carry trade profitability commodity currencies offer high interest rates on average while countries that export finished goods tend to have low interest rates we develop a general equilibrium model of international trade and currency pricing where countries have an advantage in producing either basic inputs or final goods in the model domestic production insulates commodity producing countries from global productivity shocks forcing final good producers to absorb them commodity currency exchange rates and risk premia increase with productivity differentials and trade frictions these predictions are strongly supported in the data this article is protected by copyright all rights reserved

symposium on democracy and development academic fashions often follow the public political mood in a period when euphoric public commentators have announced the end of history in the triumph of capitalist democracy one sees an increasing number of scholarly studies attempting to show often on the basis of crosscountry statistical evidence and a bit of wishful thinking a positive effect of democracy on development it is in this context refreshing to see the agnostic results reported by adam przeworski and fernando limongi in their paper on the basis of their review of the theoretical arguments and statistical studies they conclude rather bluntly we do not know whether democracy fosters or hinders economic growth their brief but fairly exhaustive examination of the various statistical studies of the last few decades shows the studies to be hopelessly inconclusive and beset with serious methodological problems at the analytical level they argue that it is not at all clear if democracy with its slow empowerment of the less wealthy secures growth fostering capitalist property rights better than dictatorships democracies may actually be more susceptible to pressures for immediate consumption and other particularistic demands that may hamper long run investment on the other hand authoritarian rulers who have the capacity to resist such pressures may instead be self aggrandi zing plundering the surplus of the economy in fact authoritarian regimes may come in different kinds some deriving their legitimacy from providing order and stability some from rapid growth sah 1991 has argued that authoritarian regimes exhibit a larger variance in economic performance than democracies

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

estimating the effects of the container revolution on world trade many historical accounts have asserted that containerization triggered complementary technological and organizational changes that revolutionized global freight transport we are the first to suggest an identification strategy for estimating the effects of the container revolution on world trade our empirical strategy exploits time and cross sectional variation in countries first adoption of container facilities and combines it with product level variation in containerizability and container usage applying our container variables on a large panel of product level trade flows for the period 1962 1990 our estimates suggest economically large concurrent and cumulative effects of containerization and lend support for the view of containerization being a driver of 20th century economic globalization

a copula garch approach for analyzing dynamic conditional dependency structure between liquefied petroleum gas freight rate product price arbitrage and crude oil price abstract global liquefied petroleum gas lpg trade shows an increasing trend but is under researched this paper focuses on the lpg market and aims to model the dependence dynamics among lpg freight rates crude oil price and propane location arbitrage conditional copula garch model is applied to estimate dependencies different types of copulas with both time invariant and time varying dependence structures are fitted and their suitability has been compared the findings suggest that firstly baltic lpg blpg freight rate and the arbitrage between propane far east and middle east prices have conditional time varying dependence and the dependence is higher in market downturns furthermore blpg and the arbitrage between far east and us propane prices have symmetric dependence and such a relationship has strengthened since 2013 secondly middle east propane price is found to have the strongest correlation with crude oil prices compared to far east and us propane prices indicating higher sensitivity to crude oil price changes last but not least the relationship between crude oil and blpg is relatively weak and mostly positive

long range growth economic development in the global network of air links we study the impact of international long distance flights on the global spatial allocation of economic activity to identify causal effects we exploit variation due to regulatory and technological constraints which give rise to a discontinuity in connectedness between cities at a distance of 6000 miles we show that these air links have a positive effect on local economic activity as captured by satellite measured night lights to shed light on how air links shape economic outcomes we first present evidence of positive externalities in the global network of air links connections induce further connections we then find that air links increase business links showing that the movement of people fosters the movement of capital in particular this is driven mostly by capital flowing from high income to middle income but not low income countries taken together our results suggest that increasing interconnectedness generates economic activity at the local level by inducing links between businesses but also gives rise to increased spatial inequality locally and potentially globally

asymmetric tournaments equal opportunity laws and affirmative action some experimental results this paper assesses whether affirmative action programs and equal opportunity laws affect the output of economic agents more precisely we find that equal opportunity laws and affirmative action programs always benefit disadvantaged groups equal opportunity laws also increase the effort levels of all subjects and hence the profits of the tournament administrator usually the firm the effects of affirmative action programs depend on the severity of a group s cost disadvantage when the cost disadvantage is severe these programs significantly increase effort levels and hence profits the opposite is true when the disadvantage is slight

trade blocs currency blocs and the reorientation of world trade in the 1930s we analyze the impact of commercial and financial policies on the reorientation of trade in the 1930s we report evidence that commercial policies attenuated prior connections between income growth and trade and that exchange rate instability marginally discouraged international trade in contrast the tendency toward regionalization commonly ascribed to the formation of trade and currency blocs was already evident to a considerable extent prior to the regional policy initiatives of the 1930s this reorientation is more properly attributed to ongoing historical forces such as commercial and financial links between countries forged over many years

global value chains a survey of drivers and measures global value chains gvcs emerged as the paradigm for the international organisation of production for most goods and services production is nowadays vertically fragmented across different countries and this reality gave rise to a significant new strand of research in in ternational trade this article starts by discussing the major driving forces of gvcs in recent decades next it surveys the main measures of gvcs accounting for their different scopes and required datasets the artic le highlights the timing of the contributions to the literature signalling their sequential nature and the trend towards more accurate and data demanding indicators

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

the international effects of china s growth trade and education booms china s international trade flows have increased by 500 since 1992 far outstripping gdp growth likewise tertiary education enrollments have increased by 300 we simulate these changes using a multi sector growth model of the chinese and usa economies a decade of trade biased growth in china is found to have a large effect on the usa economy raising gdp approximately 3 4 5 percentage points we also show that the trade bias in china s growth accounts for more than half of the observed growth in tertiary enrolments in china in contrast neutral growth has practically no effect on usa incomes or china s stock of skilled labour finally the simulations reveal that china s education boom per se has practically no long run impact on the usa economy the results thus indicate that the pattern of productivity growth in exports sectors as might be caused by falling trade costs has been critical in transmitting benefits of chinese growth to the world economy they also point to an important link between falling trade costs and human capital formation

quality competition and pricing to market a unified framework for the analysis of bilateral unit values author affiliation michael j ferrantino michael ferrantino usitc govrobert m feinberg feinber american edulauren deason l deason cgiar org acknowledgment this article represents solely the views of the authors and does not represent the views of the u s international trade commission or any of its commissioners we thank john pepper and two anonymous referees for helpful comments on an earlier draft the timely assistance of ronald jansen and his team at the united nations statistical division with various puzzles involving the comtrade data is gratefully acknowledged as is the thorough editorial assistance of peg hausman 1 introductionthe abundance of data on unit values in trade has generated a large number of explorations into the stylized facts generating them unit values defined as value of imports divided by import quantities are traditionally used as the best proxy for price data in international trade at relatively disaggregated trade categories the present article presents a unified framework for identifying systematic variation in unit values using multilateral data at the harmonized system hs 6 level this compares to research on unit values that is motivated either by supply side considerations relating to product quality associating higher unit values with exporters per capita income or demand side considerations of pricing to market associating higher unit values with importers per capita income the former work includes schott 2008 focusing on china and fontagne gaulier and zignago 2008 which use a unit value classification to motivate an extended gravity model of trade flows the latter is exemplified by alessandria and kaboski 2007 and co 2007 1most of this work except for fontagne gaulier and zignago et al tends to focus on a single exporter or importer rather than on the multilateral trade data we employ or on a particular motivation for variation in unit values in trade while fontagne gaulier and zignago do employ multilateral data in examining importer and exporter income effects on unit value they do not allow these effects to vary by product and focus mainly on results generated by restricting the set of products considered to include only manufactured goods our findings are largely consistent with those of fontagne gaulier and zignago however our analysis at the product level for a more diverse set of goods allows us to explore how importer and exporter income effects vary across products we find that both exporter income effects and importer income effects are important in determining trade prices but that exporter income effects are more prevalent and tend to be larger in magnitude the variation in the size of these effects across industries is indicative of the relative degree of product homogeneity table 1 illustrates the type of variation one finds in the unit value data for a particular hs 6 subheading watches excluding wristwatches with cases of or clad with precious metal electrically operated 2 the example which reflects the largest trade flows for this subheading in quantity terms 3 illustrates several features which are frequently observed for a wide variety of products first the range in unit values is very broad amounting to three or four orders of magnitude exports from switzerland to great britain have a unit value of 1001 68 while exports from china to japan sell for 0 56 apiece these are highly unlikely to represent the same product second higher income countries tend to sell a higher priced product in this sample swiss watches are always higher priced than chinese watches third higher income countries tend to pay more for products in this category compare imports of great britain and the netherlands versus imports of bulgaria south africa and mexico fourth there are observations that are exceptions to both the second and third rules

the shrinking advantage of market potential abstract how does a country s economic geography evolve along the development path this paper documents recent employment growth in 18 961 regions in eight of the world s main economies overall market potential is losing importance as a correlate of local growth while local employment density is gaining importance in mature economies growth is strongest in low market potential areas in emerging economies the opposite is true though the association with market potential is also weakening there structural transformation away from agriculture can account for some of the observed changes the part left unexplained by structural transformation is consistent with a standard economic geography model that yields a bell shaped relation between trade costs and the growth of centrally located regions

will affirmative action policies eliminate negative stereotypes a key question concerning affirmative action is whether the labor market gains it brings to minorities can continue without it becoming a permanent fixture in the labor market the authors argue that this depends on how the policy affects employers beliefs about the productivity of minority workers they study the joint determination of employer beliefs and worker productivity in a model of statistical discrimination in job assignments the authors prove that even when identifiable groups are equally endowed ex ante affirmative action can bring about a situation in which employers correctly perceive the groups to be unequally productive ex post copyright 1993 by american economic association

affirmative action and labor markets affirmative action remains controversial the controversy extends from the original antidiscrimination legislation and its interpretation to estimates of affirmative action s effect on the labor market this paper provides a progress report on our recent efforts at detecting the effects of affirmative action on minority wages and employment although we find a substantial increase in wages for black men and black women over our sample period the timing of these wage changes is surprising most of the wage gains came prior to 1974 before the establishment of an effective monitoring structure for affirmative action indeed when the powers of the eeoc and ofcc are greatest the wage effects for young blacks are somewhat perverse using eeo 1 reports we find a major shift in black employment toward firms most vulnerable to the monitoring and potential sanctions of the affirmative action programs as with wages the shift in minority employment came prior to the expansion of the powers and budgets of the ee

the nature of outsourcing relationships evidence from oap prices i introduction the dramatic growth in international outsourcing has fueled the expansion of international trade and deepened international integration 1 developments in outsourcing attract public attention due to concern that improvements in information technologies enable companies to relocate production or assembly activities to lower cost overseas locations 2 however while international outsourcing allows firms to take advantage of factor price differences grossman and helpman 2005 demonstrate that country cost differences are not sufficient by themselves to guarantee outsourcing as international outsourcing decisions are based on many factors including the costs of search and customization more generally new research in international trade recognizes information as a key element in the globalization process however informational improvements such as reduced communication costs or increasingly sophisticated bar code transmission and management tools may not affect all producers uniformly as ranch and trindade 2003 show product differentiation in consumption or production when combined with informational uncertainty produces a degree of natural protection for this reason information technology improvements are likely to deliver the greatest increases in global integration for those markets where the matching of differentiated partners is critical to the formation of new international partnerships similarly as noted by antras 2003 and bernard et al 2010 the organization of a firm s global operations depends further on factors including the importance of headquarters investments and the degree of product contractibility 3 a key goal of this paper is to study whether outsourcing decisions are consistent with outsourcing models that feature search and adaptation costs to this end this paper studies u s outsourcing conducted under the auspices of the overseas assembly program or oap the oap program was designed to allow firms to avoid tariffs on u s origin inputs that they utilized in final goods they assembled overseas thus while the oap does not include all u s outsourcing activities it does not capture u s assembly of foreign parts or overseas contract manufacturing that is based on u s designs and specifications oap imports provide insight into a wide swath of u s outsourcing and represented 8 5 of u s import value during the sample period since the oap provides tariff benefits to manufacturers who use u s inputs in their overseas production it is administered by u s customs consequently while the oap provides insights into manufacturing outsourcing decisions it does not provide information on developments in services outsourcing since oap exempts u s inputs from tariffs the program requires participating firms to provide detailed information on the u s and foreign content of their outsourcing imports thus oap data records facilitate the precise measurement of cost shocks and trade frictions at the country product level in particular heterogeneity in input choices both across countries and products can be exploited to identify cost pass through and general price responses for outsourcing imports for example year by year pass through can be estimated by regressing yearly oap price changes at the product country level on product country cost changes plots of the year by year coefficients in figure 1 show that the raw rate of oap pass through ranged from 6 to 23 4 however accurate outsourcing pass through estimation requires a theory based estimation framework that controls for economic factors that also influence price decisions this paper adopts feenstra s 1989 passthrough model which is modified to account for the cost structure and tariff treatment facing outsourcing firms who produced products for import under the oap this framework which is based on a bertrand model of competition in internationally differentiated goods focuses its attention on cost pass through and on the degree to which producers emulate the price changes of their competitors

indirect measures of trade costs limitations and caveats abstract trade barriers which include transportation costs tariffs language barriers and bureaucratic red tape play a key role in the determination of trade flows because direct measures are only available for a few components researchers have developed so called indirect measures of trade costs which estimate bilateral trade integration from cross sectional variation in observed trade flows the paper explores the theoretical and empirical determinants of these indirect measures of trade costs the results suggest that while they do capture variation in trade barriers the indirect measures may also reflect variation in other factors such as differences in tastes and production costs

declining distance effects in international trade some country level evidence technical progress can be expected to reduce transport costs over time yet most studies of bilateral trade based on the gravity model find distance effects to be increasing rather than decreasing we investigate countries openness to international trade the ratio of exports plus imports to gdp we find that trade decreases with geographical remoteness land area and lack of access to the sea all of which are likely to be correlated with transport costs in contrast to the results obtained with log linear models of bilateral trade distance effects remoteness and land area have declined over time trade decreases with population density and increases with improvements in the terms of trade investment and a more liberal trade policy

the trade reducing effects of market power in international shipping abstract developing countries pay substantially higher transportation costs than developed nations which leads to less trade and perhaps lower incomes this paper investigates price discrimination in the shipping industry and the role it plays in determining transportation costs in the presence of market power shipping prices depend on the demand characteristics of goods being traded we show theoretically and estimate empirically that ocean cargo carriers charge higher prices when transporting goods with higher product prices lower import demand elasticities and higher tariffs and when facing fewer competitors on a trade route these characteristics explain more variation in shipping prices than do conventional proxies such as distance and significantly contribute to the higher shipping prices facing the developing world a simple back of the envelope calculation suggests that eliminating market power in shipping would boost trade volumes by 5 9 for the us to 15 2 for latin america our findings are also important for evaluating the impact of tariff liberalization cargo carriers decrease shipping prices by 1 2 for every 1 reduction in tariffs

implications of comtrade compilation practices for trade barrier analyses and negotiations u n commodity trade comtrade statistics have major shortcomings for many analyses relating to tariffs and other trade barriers the use of a cost insurance freight valuation base for these data results in an upward sometimes severe bias in the implied dutiable value of imports for countries that utilize free on board tariffs this problem can be greatly exacerbated by the general trade system procedure used to compile the u n statistics as opposed to the special trade practice used for the world trade organization integrated database u s international trade commission statistics show that the combined effects of these biases can reach magnitudes that preclude the legitimate use of comtrade for many tariff trade simulations or related trade negotiations

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

causes of world trade growth in agricultural and food products 1951 2000 a demand function approach the objective of the present study is to analyse the causes of the growth of international agricultural and food trade in volume terms from 1951 to 2000 the results suggest that income growth has been the principal reason for this expansion while exchange rate stability and the real price of agricultural products played only a minor role multilateral trade liberalization and trade costs given their long term stability are not elements that could have stimulated their growth finally the intensive liberalization of trade which took place in various economic regions especially in europe became a key factor in promoting agricultural trade among the countries participating in regional trade agreements the study results also indicate that the determinants of trade growth for these goods were different to those for other goods and other periods

is there a social kuznets curve the influence of labour standards on inequality abstract this study empirically investigates the impact of core labour standards on income inequality for a range of 90 countries from 1990 2000 a synthetic index of labour standards is computed by means of a multiple correspondence analysis and no significant correlation is found with the gini index one of the reasons pointed out is that the effective implementation of core labour standards depends on the quality of the country s political and legal systems using instrumental variables in a tsls model we found an inverse u shaped curve between the new endogenous index of core labour standards and income inequality

job discrimination market forces and the invisibility hypothesis the invisibility hypothesis holds that the job skills of disadvantaged workers are not easily discovered by potential new employers but that promotion enhances visibility and alleviates this problem then at a competitive labor market equilibrium firms profit by hiding talented disadvantaged workers in low level jobs consequently those workers are paid less on average and promoted less often than others with the same education and ability as a result of the inefficient and discriminatory wage and promotion policies disadvantaged workers experience lower returns to investments in human capital than other workers

choice among wage hours packages an empirical investigation of male labor supply this article specifies and estimates an empirical model of male labor supply based on an implicit market model of wage hours determination we discuss how moving from a standard labor supply model to an implicit market model affects model specification and choice of estimation technique we find that average hourly earnings are not independent of hours worked and that ols estimates of the wage hours relationship are biased we also show that a labor supply model that assumes wages to be independent of hours worked produces a positively biased estimate of the effect of the wage on labor supply

equity and efficiency in human capital investment the local connection a general model of community formation and human capital accumulation with social spillovers and decentralized school funding is used to analyse the causes of economic segregation and its consequences for equity and efficiency significant polarization arises from minor differences in endowments preferences or access to capital markets this makes income inequality more persistent across generations but the same need not be true for wealth equilibrium stratification tends to be excessive resulting in low aggregate surplus whether state equalization of school resources can remedy these problems hinges on how purchased social and family inputs interact in education and in mobility decisions

the enforcement of equal opportunity laws under imperfect information affirmative action and alternatives more than twenty years have passed since the enactment of the civil rights act during that period the enforcement of title vii with its broad prohibition of discrimination in employment and compensation has proved to be both difficult and controversial as part of any attempt to regulate economic activity we must be able to observe violations but unequal treatment in employment relationships is difficult to identify employers must always differentiate between individuals when making hiring and promotion decisions since applicants possess diverse skills and abilities this diversity creates a fundamental problem in monitoring the compliance or noncompliance of employers with equal opportunity laws this paper examines the enforcement of equal opportunity laws in a labor market that exhibits statistical discrimination this type of discrimination may arise as a rational response by profitmaximizing firms to imperfect information about individual productivity in lundberg and startz 1983 an equal opportunity policy prohibiting raceor sex specific wage schedules was shown to be an efficiency enhancing response to statistical discrimination section ii extends this model to allow information a role in allocating heterogeneous workers among jobs in this environment restricting firms use of information through an equal opportunity policy improves workers incentives to acquire human capital at the expense of production losses and its net effect on efficiency becomes ambiguous firms will attempt to evade an equal opportunity law presenting the government and the courts with the task of monitoring and enforcing compliance the regulators are likely to possess imperfect information not only about the relationship between worker characteristics and productivity but also about the actual personnel policies followed by firms in section iii a simple costminimizing evasion policy for firms in which other worker attributes are used as imperfect proxies for race or sex is outlined in the next two sections alternative policies for enforcing compliance

the international reorganisation of auto production this paper analyzes the patterns of bilateral trade flows of auto components over the last decade by applying network analysis results show the rise of a number of emerging economies in asia and central and eastern europe as important parts suppliers but their role is still largely peripheral in fact there was a strengthening of the world s leading producers with a more hierarchical division of labor within their regions especially in europe regionalization of production declined in all of the groups of auto parts examined with the exception of electrical parts where a regional production network is emerging in asia

factor proportions and the growth of world trade abstract most of the expansion of global trade since 1980 has been of the north south kind between capital abundant developed and labour abundant developing countries based on this observation i argue that the recent growth of world trade is best understood from a factor proportions perspective using data on trade barriers and estimates of capital labour ratios for a group of 45 economies between 1980 and 2008 i find that a calibrated factor proportions model can generate significant trade growth during this period amounting to 90 of the observed rise in north south trade the opening up of china alone accounts for three quarters of the predicted increase in line with the model i present evidence that china s liberalisation has raised the exports and imports of capital abundant countries relative to more labour abundant economies overall my findings suggest that factor proportions theory may be useful for interpreting several quantitative and qualitative aspects of growing world trade in a period during which the group of large open economies has become significantly less homogenous

airplanes and comparative advantage abstract airplanes are a fast but expensive means of shipping goods a fact which has implications for comparative advantage the paper develops a ricardian model with a continuum of goods which vary by weight and hence transport cost comparative advantage depends on relative air and surface transport costs across countries and goods as well as stochastic productivity a key testable implication is that the u s should import heavier goods from nearby countries and lighter goods from faraway counties this implication is tested using detailed data on u s imports from 1990 to 2003 looking across goods the u s imports nearby exporters have lower market share in goods that the rest of the world ships by air looking across exporters for individual goods distance from the us is associated with much higher import unit values these effects are large which establish that the model identifies an important influence on specialization and trade

global production sharing exploring australia s competitive edge cross border dispersion of production processes within vertically integrated global industries global production sharing has been an increasingly important structural feature of economic globalisation in the recent decades this paper examines patterns and determinants of global production sharing with an emphasis on how australian manufacturing fits into global production networks gpns though australia is a minor player in gpns there is evidence that australian manufacturing has a distinct competitive edge in specialised skill intensive tasks in several industries such as aircraft medical devices machine tools measuring and scientific equipment and photographic equipment specialisation in high value to weight components and final goods within gpns which are suitable for air transport helps australian manufacturing to overcome the tyranny of distance in world trade being predominantly relationship specific australian gpn exports are not significantly susceptible to real exchange rate appreciation

customer discrimination and affirmative action i introduction beginning with the work of becker 1957 economists have been concerned with the relationship between competitive market forces and the persistence of labor market discrimination 1 a major insight of becker and the literature that followed is that competition could tend to eliminate discriminatory pay differentials if competitive forces do eliminate discrimination then empirical findings of persistent discrimination are either a result of faulty testing or market imperfections economic analysis of the link between competition and discrimination depends on the origins of prejudice becker identified at least three possible sources employers co workers and consumers 2 in each of these instances the group against which prejudice is directed e g women or minorities which will be termed minorities in this paper may be able to escape discrimination first minorities can work for nondiscriminatory employers if there are any moreover stiglitz 1973 shows that with constant returns to scale such employers will take over markets from the discriminators eliminating any pay gap based on prejudice 3 second if there is co worker prejudice then minorities can work in segregated firms which under constant returns to scale may have a cost advantage over integrated or all majority firms again discrimination will be driven away 4 third minorities can theoretically escape customer discrimination by specializing in the production of goods for which there is no contact between producers and consumers a case discussed by cain 1986 while competitive forces may in some cases erode discriminatory wage differentials the rate of decline of race and sex wage differentials has evidently not been rapid enough in the eyes of policymakers u s anti discrimination policy has been guided by two major vehicles title vii of the 1964 civil rights act and the office of federal contract compliance programs ofccp 5 the equal employment opportunity commission eeoc was created to enforce title vii and is empowered to aid plaintiffs or bring suit itself against employers the commission monitors the employment practices of federal contractors not only are contractors barred from discrimination against protected groups these firms are also required to take affirmative action not to discriminate the purpose of this paper is twofold first it demonstrates that in a general equilibrium framework the case of customer discrimination is theoretically distinct from employer or co worker prejudice in particular while constant returns to scale and the existence of nondiscriminatory firms can eliminate the latter two forms of discrimination customer discrimination may persist even under such conditions the persistence of discriminatory wage differentials is shown to depend on consumer demand technology and the relative size of the minority labor force 6 second the general equilibrium framework is then used to evaluate the impact of government anti discrimination policy where customers are the source of discrimination it is shown that if the government requires equal pay and proportional representation for minorities then the resulting allocation of resources will under particular assumptions be the same as if customers did not discriminate i then contrast these theoretical results with the predicted general equilibrium impact of affirmative action when there is employer or co worker prejudice among previous general equilibrium models of affirmative action welch 1976 assumed no discrimination while freeman 1978 did not specify the source of discrimination it is shown here that the source of prejudice markedly affects one s conclusions about affirmative action further even in some cases where segregation has eliminated discriminatory wage differentials the introduction of affirmative action has allocative effects finally evidence from studies evaluating the impact of affirmative action is used to distinguish among the various equilibrium models

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

the place premium bounding the price equivalent of migration barriers large international differences in the price of labor can be sustained by differences between workers or by natural and policy barriers to worker mobility we use migrant selection theory and evide

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

capital flight to germany two alternative measures abstract we use two measures to study two capital flight channels for germany one measure is based on the concept of trade misinvoicing and one on net claims and liabilities in the eurosystem of central banks for both measures we propose refinements to enhance the assessment of capital flight we find that capital flight towards germany via these two channels has been quite sizable in the recent decade and can tally to about 2 of gdp annually regarding their determinants we show that the two capital flight measures are driven by both common and measure specific factors traditional determinants such as covered interest differentials only play a limited role while crisis specific factors such as economic policy uncertainty the ecb collateral policy as well as currency misalignment are driving factors of the investors apparent flight to safety behavior

mnes location strategies and labor standards the role of operating and reputational considerations across industries we investigate the role of local labor standards on mnes location decisions across different sectors and sub national regions within a developing country we suggest that foreign investors adopt selective location strategies in connection with specific labor standards as a result of reputational and operating considerations foreign firms in more hazardous sectors prefer locations with higher occupational health and safety standards because they are more exposed to reputational risks those in sectors with less reversible investments prefer locations with lower degrees of unionization because their lower bargaining power increases their sensitivity to operating costs we test our arguments across 26 sub national turkish regions over the period 2005 2011

core labor standards and development impact on long term income summary the paper focuses on the impact of international core labor standards on long term per capita income in order to do that it is necessary to build a new synthetic indicator of labor standards using multiple correspondence analysis measuring the four core labor standards recognized by ilo we propose an estimation of the steady state per capita income for a large panel of countries 104 and then that of developing countries the two stage least square method is used to correct potential problems of endogeneity the findings show that by and large countries with higher labor standards have a higher steady state level 2007 elsevier ltd all rights reserved

the nature of oil shocks and the global economy abstract this paper identifies the main driving force behind oil price shocks in 1970 2006 by applying a simple identification strategy of supply driven and demand driven price shocks the identification hypothesis states that supply driven oil price shocks have a negative impact on the macroeconomic activity of countries which are net consumers of oil while demand driven oil price shocks do not have negative effects in order to identify global demand driven shocks a weighted aggregate gdp series of countries which are net consumers of oil is constructed over 1970 2006 the key result is that the main driving force behind oil price shocks has changed from supply driven shocks in 1970 1992 to demand driven shocks in 1992 2006

heterogeneous trade costs and wage inequality a model of two globalizations abstract we develop a model for analyzing the distributional effects of two globalizations and their interdependence we distinguish between two trade cost reductions i trade liberalizations in the 1980s which increased trade in low skill intensive goods denoted l globalization and ii reductions in communication costs due to the it revolution which raised trade in middle skill intensive goods during the 1990s denoted c globalization we consider a north south trade economy in which the north is skill abundant a freely traded final good is produced using high skill services and a bundle of inputs inputs differ on the intensity of middle and low skill workers required to be produced and are subject to heterogeneous trade costs in the north we find that wage inequality increases in the l globalization during the c globalization wage polarization emerges the relative wage of high to middle skill workers increases while the relative wage of middle to low skill workers is hump shaped we find a complementarity between the two globalizations wage polarization is delayed by the extent of trade in the l globalization in the south we find that wage inequality increases in both globalizations finally we show how asymmetric participation in the c globalization of two southern countries generates a discontinuous pattern of specialization the southern country participating in the c globalization specializes in the least and most skill intensive traded inputs

is lunch and other break time productive in sweden a hedonic earnings approach this hedonic earnings analysis suggests that in sweden in the mid 1980s break time was overall productive at the margin a result that contrasts with findings from similar studies using u s data among workers in male jobs however break time for meals appears to have been significantly less productive at the margin than normal work to try to account for the male job effect the author explores the possibility that high productivity workers took longer breaks than other workers in response to high marginal tax rates union induced wage compression or both the results of his further analysis suggest that union induced wage compression may have contributed to the male job effect but he finds no support for the tax rate explanation

spatial linkages and export processing location in china this paper provides empirical evidence that spatial linkages matter for the localisation of global value chain activities relying on processing trade data for chinese provinces during the period 1997 2008 we investigate whether a chinese province s proximity to international suppliers and international buyers within an industry chain affects its attractiveness as an export processing location we find that the upstream and downstream spatial linkages both have a strong and independent explanatory power we also explore what factors explain the influence of these spatial linkages

trade credit in zimbabwean manufacturing abstract credit from suppliers is an important but often neglected source of finance for manufacturing firms zimbabwe is no exception unlike credit from financial institutions trade credit does not rely on formal collateral but on trust and reputation contract enforcement is flexible network effects and statistical discrimination affect the screening of trade credit applicants black entrepreneurs are disadvantaged by their lack of business contacts and by the difficulty of distinguishing themselves from the mass of financially insecure and short lived african owned businesses in zimbabwe a vicious circle is created between weak financial base unreliability as a debtor and inability to gain access to credit

the quality income effect and the selection of location we analyze a location choice model with two vertically differentiated firms and two regions with different consumer income we find that the high quality producer settles in the poor region and the low quality one in the rich region when income disparities are sufficiently high and goods are differentiated enough this apparently counter intuitive result is not determined by technology or size issues rather it relies on the relationship between regional income disparities and product quality which we call the quality income effect

how do the trans pacific economies affect the usa an industrial sector approach this paper studies how the trans pacific region affects the us economy in terms of business cycle transmission we use a large data set consisting of disaggregated sectoral industrial production indexes from selected countries in the region and employ a factor augmented vector autoregression favar approach to analyse the transmission of shocks in different industries we find that a positive output shock in the entire trans pacific region has positive effects on the majority of us manufacturing sectors we also find that sectoral shocks in five sectors of the trans pacific region have a large impact on the overall us economy three of the five sectors displayed strong same sector responses relative to the overall response suggesting that vertical production linkages might play a key role in the transmission of shocks our results highlight the importance of examining industrial sectors in studying the transmission of shocks in the trans pacific region

biased screening and discrimination in the labor market the traditional economic analysis of discrimination is based on gary becker s study of taste discrimination by employers employees and consumers more recent work by kenneth arrow 1972 1973 has attempted to interpret intergroup wage differences in an alternative framework as a rational reaction to uncertainty in labor markets his model of statistical discrimination demonstrates that when the screening process used to determine a worker s qualifications is costly and prior expectations of productivity differ across race or sex groups then wage differentials may arise between workers of identical productivity by implicitly assuming a perfect screening process arrow ignores a potentially important source of wage differentials namely the fact that the screening process might be a more reliable predictor of productivity for one group than for another our paper generalizes the arrow model in two ways first in contrast to arrow we assume that all groups have identical distributions of productivity secondly the screening process used by the firm to determine an applicant s productivity is biased in the sense that a members of various groups may pass the test in different proportions despite their identical productivity distributions and b the predictive power of the test might vary across groups our objective is to analyze the effects of these types of biases in the screening process on the wage differentials between different population groups

endogenous pricing to market and financing costs abstract this paper explains why relative ppp should hold more tightly in emerging markets and why pricing to market would be observed more frequently in the oecd countries it studies the endogenous determination of pricing to market in a real option model with time dependent transportation costs where the future terms of trade are random allowing time dependent transportation costs adds a dimension of investment to the pre buying of imports implying that financial considerations determine the frequency of pricing to market and the deviations from relative ppp if the expected discounted cost of last minute delivery is higher than pre buying one exercises the option of spot market imports if the realized terms of trade are favorable enough pricing to market is observed in countries characterized by low terms of trade volatility and low financing costs in these circumstances imports are pre bought and the spot market for imports is inactive in countries where the financing costs and the terms of trade volatility are high few imports are pre bought the price of imports is determined by the realized real exchange rate and a version of relative ppp holds with an intermediate level of terms of trade volatility and of financing costs a mixed regime is observed if the realized real exchange rate is weak pricing to market would prevail increasing consumers welfare by shielding them from the adverse purchasing power consequences of weak terms of trade if the realized real exchange rate is favorable enough more imports are purchased in the spot market and the relative ppp would hold higher financing costs increase the cost of pre buying imports reducing thereby the frequency of pricing to market increasing the expected relative price of imports reducing the expected deviations from relative ppp and reducing welfare

a gravity criterium for discriminating traditional protection measures abstract the case of spain in the first globalization illustrates how the gravity equation as a tool from which to derive a comprehensive measure of trade costs can be used to test the soundness of alternative direct measures of specific costs

gender and job performance evidence from wall street this study concerns the relationship between gender and job performance among brokerage firm equity analysts women s representation in analyst positions dropped from 16 percent in 1995 to 14 percent in 2005 the study found significant gender based differences in performance on various dimensions for example women cover roughly 9 stocks on average as compared with 10 for men and women s earnings estimates tend to be less accurate than men s estimates but the study also found that women are significantly more likely than men to be designated as all stars which indicates that they outperform men in other aspects of job performance

measuring international trade costs the costs of international trade have become an increasingly important item in trade negotiations under the heading trade facilitation and element of trade theory but definition and measurement of trade costs remain in their infancy this paper argues that the most conceptually appropriate measure is the gap between cost insurance freight cif and free on board fob values of traded goods but that this must be measured on a consistent volume of trade such data are only available for a few countries we calculate cif fob gap values for the three largest trading nations that report such data australia brazil and the usa these values provide plausible estimates of ad valorem trade costs for the three importing countries and for all countries exports the estimates indicate that although trade costs have fallen over the last two decades average trade costs now exceed the average tariff rate on imports into the usa and australia country rankings by the cif fob gap values differ significantly from those by commonly used proxies for trade costs such as the indicators of time and cost in the world bank s doing business database and analysis based on such proxies is likely to produce misleading results
