the optimal indexation of asymmetric information contracts the indexation of labour contracts is examined in a setting from which the hedging motive for partial indexation has been excluded since firms have better information than workers contracts must satisfy an incentive compatibility constraint the optimal degree of indexation depends on the incentives generated by the best fully indexed contract if firms would understate overstate the productivity of labour under this contract the optimal contract is partially more than fully indexed l indexation optimale des contrats quand l information est asymetrique l auteur examine l indexation de contrats de travail dans un monde dont on a elimine l indexation partielle dans le simple but de se couvrir comme les firmes ont une meilleure information que les travailleurs les contrats doivent satisfaire une contrainte de compatibilite le degre optimal d indexation depend des incitations engendrees par le meilleur contrat pleinement indexe si les firmes sous evaluent sur evaluent la productivte des travailleurs dans le contrat le contrat optimal est partiellement plus que pleinement indexe

involuntary unemployment and implicit contracts this paper provides an explanation of involuntary umemployment arising as a consequence of asymmetric information between firms and workers involuntary unemployment is defined as a situation where ex post gains to trade exist a model of labor contracts is developed where the allocations are not ex post optimal it is shown that inferiority of leisure is a necessary and sufficient condition for the existence of involuntary unemployment

wage employment contracts this paper studies the efficient agreements about the dependence of workers earnings on employment when the employment level is controlled by firms the firms superior information about profitability conditions is responsible for this form of contract governance under plausible assumptions such agreements will cause employment to diverge from efficiency as a byproduct of their attempt to mitigate risk it is shown that if leisure is a normal good and firms are risk neutral employment is always above the efficient level such a one period implicit contracting model cannot therefore be used to explain unemployment as a rational byproduct of risk sharing between workers and a risk neutral firm under conditions of asymmetric information

implicit contracts moral hazard and unemployment this paper considers a firm whose marginal revenue product of labor is a random variable we derive the form of an optimal long term contract between workers and the firm under the assumption that labor s marginal product is observed by the firm but not by the workers we show that the existence of asymmetric information causes unemployment to be greater than in a situation where information about labor s marginal product is public or where employment is determined in spot markets in particular unemployment can occur when the marginal product of labor exceeds the reservation wage

trade facilitation and manufactured exports is africa different summary trade facilitation defined as reducing the transaction costs associated with the enforcement regulation and administration of trade policies has been at the forefront of discussions on policy measures for reducing the costs of exporting and importing in developing countries this study uses a new panel dataset for 124 developed and developing countries available for the period 2003 04 to assess the impact of trade facilitation and other trade related institutional constraints on manufacturing export performance with particular reference to africa we estimate a standard gravity model augmented with trade facilitation regulatory quality and infrastructure indicators our results show that trade facilitation reforms could contribute to improve export performance in africa but other reforms including the quality of the regulatory environment and the quality of the basic transport and communications infrastructure are also needed furthermore improvements in on the border and behind the border policies yield a higher return in terms of increasing manufacturing export performance in african countries than in the rest of the world

trade facilitation and economic development new approach to quantifying the impact this article analyzes the relationship between trade facilitation and trade flows in the asia pacific region country specific data for port efficiency customs environment regulatory environment and e business usage are used to construct indicators for measuring trade facilitation the relationship between these indicators and trade flows is estimated using a gravity model that includes tariffs and other standard variables enhanced port efficiency has a large and positive effect on trade flows regulatory barriers deter trade improvements in customs and greater e business use significantly expand trade but to a lesser degree than improvements in ports or regulations the benefits of specific trade facilitation efforts are estimated by quantifying differential improvements in these four areas among members of the asia pacific economic cooperation apec a scenario in which apec members with below average indicators improve capacity halfway to the average forall members shows that intra apec trade could increase by dollar 254 billion or 21 percent of intra apec trade flows

intra industry foreign direct investment we use a new firm level data set that establishes the location ownership and activity of 650 000 multinational subsidiaries close to a comprehensive picture of global multinational activity a number of patterns emerge from the data most foreign direct investment fdi occurs between rich countries the share of vertical fdi subsidiaries which provide inputs to their parent firms is larger than commonly thought even within developed countries more than half of all vertical subsidiaries are only observable at the four digit level because the inputs they are supplying are so proximate to their parent firms final good that they appear identical at the two digit level we call these proximate subsidiaries intra industry vertical fdi and find that their location and activity are significantly different to the inter industry vertical fdi visible at the two digit level these subsidiaries are not readily explained by the comparative advantage considerations in traditional models where firms locate their low skill production stages abroad in low skill countries to take advantage of factor cost differences we find that overwhelmingly multinationals tend to own the stages of production proximate to their final production giving rise to a class of high skill intra industry vertical fdi

on the empirics of foreign aid and growth the present paper re examines the effectiveness of foreign aid theoretically and empirically using a standard olg model we show that aid inflows will in general affect long run productivity the size and direction of the impact may depend on policies deep structural characteristics and the size of the inflow the empirical analysis investigates these possibilities overall we find that aid has been effective in spurring growth but the magnitude of the effect depends on climate related circumstances finally we argue that the collier dollar allocation rule should be seriously reconsidered by donor agencies if aid effectiveness is related to climate the usefulness of foreign aid in promoting growth in developing countries has been an area of controversy ever since rosenstein rodan in 1943 advocated for aid to eastern and south eastern europe browsing through successive editions of a leading textbook in development economics provides a telling illustration of how the confidence in aid effectiveness dwindled over the years in the first edition of leading issues in economic development meier 1964 dedicated a full 18 page section to the issue of foreign aid he started out asking how much aid by the time of the sixth edition meier 1995 the treatment of foreign aid had been cut into half and the questions in focus were why official assistance and does aid work in the 2000 edition meier and rauch 2000 foreign aid is not even listed in the index

missing women age and disease relative to developed countries and some parts of the developing world most notably sub saharan africa there are far fewer women than men in india and china it has been argued that as many as a 100 million women could be missing the possibility of gender bias at birth and the mistreatment of young girls are widely regarded as key explanations we provide a decomposition of these missing women by age and cause of death while we do not dispute the existence of severe gender bias at young ages our computations yield some striking new findings 1 the vast majority of missing women in india and a significant proportion of those in china are of adult age 2 as a proportion of the total female population the number of missing women is largest in sub saharan africa and the absolute numbers are comparable to those for india and china 3 almost all the missing women stem from disease by disease comparisons and not from the changing composition of disease as described by the epidemiological transition finally using historical data we argue that a comparable proportion of women was missing at the start of the 20th century in the united states just as they are in india china and sub saharan africa today

market access conditions and sub saharan africa s exports diversification summary despite some progress in the last decade sub saharan africa s participation in the global economy remains generally limited and poorly diversified among the various reasons behind the lack of competitiveness of sub saharan africa exports this paper analyzes whether changes in market access conditions affect export diversification the findings of this paper indicate that market access conditions remain important and that the presence of trade relationships depends not only on favorable market access conditions but also on how these compare relative to foreign competitors these results imply that freer trade within sub saharan african countries could provide significant incentive to intra regional trade

the colour of money earnings differentials among ethnic groups in canada the literature on ethnically based earnings differentials in canada has focused on differences either between whites and visible minorities or between particular ethnic groups in this paper the authors examine both earnings differentials between whites and visible minorities and earnings differentials within the white and visible minority groupings among both men and women they find substantial earnings differentials both between and within the white and visible minority groupings differentials between whites and visible minorities suggest that the visible minority category is a useful indicator of economic discrimination differentials within these groupings however suggest that it is only a rough indicator

export performance and trade facilitation reform hard and soft infrastructure summary we estimate the impact of aggregate indicators of soft and hard infrastructure on the export performance of developing countries we derive four new indicators for more than 100 countries over the period 2004 07 estimates show that trade facilitation reforms do improve the export performance of developing countries this is particularly true with investment in physical infrastructure and regulatory reform to improve the business environment the findings provide evidence that the marginal effect of the transport efficiency and business environment improvement on exports appears to be decreasing in per capita income in contrast the impact of physical infrastructure and information and communications technology on exports appears increasingly important the richer a country becomes we also find statistical evidence on the complementarity between hard infrastructure and soft infrastructure as captured by our indicators finally drawing on estimates we compute illustrative ad valorem equivalents of improving each indicator halfway to the level of the top performer in the region

women empowerment and economic development women empowerment and economic development are closely related in one direction development alone can play a major role in driving down inequality between men and women in the other direction empowering women may benefit development does this imply that pushing just one of these two levers would set a virtuous circle in motion this paper reviews the literature on both sides of the empowerment development nexus and argues that the interrelationships are probably too weak to be self sustaining and that continuous policy commitment to equality for its own sake may be needed to bring about equality between men and women

impacts of tangible and intangible elements of aid for trade on the globalisation of developing countries the aid for trade initiative was launched by the wto in 2005 to help developing countries build their supply side capacity and trade related infrastructure to improve their capacity in the global market this study investigates the impacts of both the tangible and intangible elements of this initiative on the economic social and political globalisation of recipient countries intangible elements of aid for trade aid for trade policy and regulation may be considered as the software of aid for trade while tangible elements aid for economic infrastructure and building productive capacity are the hardware countries that receive aid for trade can use both types of elements to succeed in globalisation this research hypothesises that the tangible elements of aid for trade have a singular effect on the overall level of globalisation since they are expected to only increase the level of economic globalisation moreover we expect that the intangible elements of aid for trade will have multiple effects on the overall level of globalisation as they have an impact on not only economic aspects but also social and political aspects of it using the dataset of aid for trade from 2002 to 2015 we find that the intangible elements of aid for trade have increased the recipients level of overall globalisation

china s one belt one road initiative the impact of trade facilitation versus physical infrastructure on exports the one belt one road obor project is perhaps china s most significant international relations initiative in recent times it is based on openness harmony inclusivity mutual benefit and market operations and aims to connect the economically vibrant east asia and the developed europe by land and by sea and in the process it brings growth and development to tens of countries along the modern silk routes in this paper we compare the impact of the main initiatives of obor namely enhancements in physical infrastructure and improvements in border administration on the trade of countries that have signed on to this project especially countries along the six economic corridors we find overwhelming evidence that shows improvements in border administration has the greatest impact on exports of corridor countries although physical infrastructure is important for trade the chinese government should place equal attention to improvements in trade facilitation to ensure trade routes operate seamlessly across the various corridors

evaluating aid for trade a survey of recent studies the demand for accountability in aid for trade is increasing but monitoring has focused on case studies and impressionistic narratives the paper reviews recent evidence from a wide range of studies recognizing that a multiplicity of approaches is needed to learn what works and what does not the review concludes that there is some support for the emphasis on reducing trade costs through investments in hard infrastructure like ports and roads and soft infrastructure like customs but failure to implement complementary reform especially the introduction of competition in transport services may erode the benefits of these investments direct support to exporters does seem to lead to diversification across products and destinations but it is not yet clear that these benefits are durable in general it is difficult to rely on cross country studies to direct aid for trade more rigorous impact evaluation is an underutilized alternative but situations of clinical interventions in trade are rare and adverse incentives because of agency problems and costs because of the small size of project are a hurdle in implementation

aid effectiveness the role of the local elite we study the importance of the local elite as a determinant of the effectiveness of foreign aid in developing countries the local elite serves as an intermediary between aid donors and aid recipients through its control of the government and major firms the likelihood of misusing aid is large if the elite is characterized by extensive economic and political power and little concern for social groups besides itself to determine which countries have this type of elite we use a historically determined variable the percentage of european settlers in total population in colonial times we provide strong empirical evidence that the level of european settlement in colonial times is negatively related to the effectiveness of foreign aid as measured in a growth regression framework our results are robust to the inclusion of a wide set of alternative explanatory factors advanced in the aid effectiveness literature

aid policies and growth the authors of this paper use a new database on foreign aid to examine the relationships among foreign aid economic policies and growth of per capita gdp in panel growth regressions for 56 developing countries and 6 four year periods 1970 93 they find that the policies that have a great effect on growth are those related to fiscal surplus inflation and trade openness they construct an index for those three policies and have that index interact with foreign aid they have instruments for both aid and aid interacting with policies they find that aid has a positive impact on growth in developing countries with good fiscal monetary and trade policies in the presence of poor policies aid has no positive effect on growth this result is robust in a variety of specifications which include or exclude middle income countries include or exclude outliers and treat policies as exogenous or endogenous they examine the determinants of policy and find no evidence that aid has systematically affected policies either for good or for ill they estimate an aid allocation equation and show that any tendency for aid to reward good policies has been overwhelmed by donors pursuit of their own strategic interests in a counterfactual they reallocate aid reduce the role of donor interests and increasing the importance of policy such a reallocation would have a large positive effect on developing countries growth rates

do developing country wto members receive more aid for trade aft since the world trade organization wto doha development agenda dda negotiations started in 2001 the importance of aid for trade aft has been well recognised as a useful tool for facilitating trade economic growth and social development in developing countries at the wto hong kong ministerial conference in december 2005 the aft initiative was launched and many high income member countries pledged to increase their aft contributions particularly for the least developed member countries ldc this paper aims to assess whether and to what extent the wto s developing member countries have received more aft for this purpose a system generalised method of moments is applied to a sample of 118 recipient countries for the period 2001 10 we find evidence that while ldc wto members on average receive relatively more aft than other developing countries the difference has not increased since launch of the aft initiative among the three categories of aft the positive wto membership effect for ldc members increased for building productive capacity and for trade policy and regulation but declined for infrastructure

employment with asymmetric information in an economy without informational and other distortions entrepreneurs and workers can write labor contracts that support a pareto optimal allocation of resources this paper is an attempt to characterize contracts when enterpreneurs are better informed about the state of nature than are their workers asymmetric information generally results in a suboptimal allocation of both risk and worker effort in particular if consumption and leisure are perfect substitutes employment will be less than fully pareto optimal in all but the most favorable states of nature

aid for trade effectiveness complementarities with economic integration developing countries are increasingly using regional integration as a main policy lever when pursuing a trade led growth strategy and today deep preferential trade agreements go beyond trade policy negotiations and cover trade facilitation issues since aid for trade aft has been recognised as a powerful instrument for increasing developing countries trade capacity by targeting internal trade costs this article tests whether complementarities exist between this type of aid and economic integration using a gravity model on panel data for the period 1995 2005 results indicate that aft when combined with economic integration has been effective in increasing trade flows both south south and north south trade flows have benefited and the combination of the two instruments has been particularly effective in expanding the south s exports to the north finally when breaking down aft into categories assistance to trade related institutions seems to generate the strongest complementarities with economic integration

aid and trade this paper surveys the recent theoretical and empirical literature that explores the relations between aid and trade and asks about the complementarity or substitution effects at work we distinguish between the effects of aid on trade flows and on trade policies of the donor as well as the recipient countries special focus is given on trade facilitation or aid for trade

assessing the benefits of trade facilitation a global perspective this paper estimates the relationship between trade facilitation and trade flows using a panel of disaggregated manufactured goods for the 2000 2001 period for 75 countries four categories of trade facilitation are defined measured and assessed for their impact on bilateral trade flows using a gravity model the four measures of trade facilitation are port infrastructure air and maritime customs environment regulatory environments and e business infrastructure the results suggest that raising global capacity halfway to the world average in the four areas would increase trade by 377 billion most regions of the world increase exports more than imports in large part this result stems from increased exports to oecd markets that is obtained through a country s own effort to improve ports customs regulations and services infrastructures in addition the results suggest that reform and capacity building in trade facilitation in areas related to gatt articles v viii and x that are under discussion at the world trade organisation could expand trade and exports significantly many of the reform measures necessary to achieve this goal need not necessarily require large scale investment projects but rather action in legal and administrative reform to facilitate trade

household specific food price differentials and high value crop production in rural ghana using panel data from ghana we have examined the relationship between household specific producer consumer price differentials and rural household cropland allocation between food and high value crops we test the hypothesis that cereal price bands induce a shift of resources away from high value crop production making smallholders appear unresponsive to price incentives our results lend support to this hypothesis implying that a policy aiming at increasing farmers income through high value crop production may fail if hard and soft infrastructure does not improve in rural areas and if staple crop productivity does not increase significantly

on the simultaneity problem in the aid and growth debate this paper shows that foreign aid has a significant positive average effect on real per capita gross domestic product gdp growth if and only if the quantitatively large negative reverse causal effect of per capita gdp growth on foreign aid is adjusted for in the growth regression instrumental variables estimates show that a 1 percentage point increase in gdp per capita growth decreased foreign aid by over 4 adjusting for this quantitatively large negative reverse causal effect of economic growth on foreign aid shows that a 1 increase in foreign aid increased real per capita gdp growth by around 0 1 percentage points

aid to the services sector does it affect manufacturing exports this paper evaluates the impact of foreign aid to five service sectors transportation information and communications technologies energy banking financial services and business services on exports of downstream manufacturing sectors in developing countries to address the reverse causality between aid and exports the analysis relies on an original identification strategy that exploits i the variation of aid flows to service sectors and ii the variation of service intensities across industrial sectors and countries using input output data the authors find a positive effect of aid to services in general on downstream manufacturing exports of developing countries across regions and income level groups

aid effectiveness opening the black box this paper examines the causality chain linking aid flows to development outcomes it argues that many of the questions policymakers and economists would like data to answer simply cannot be answered due to the complexity and noise along links in the chain and the problem of attribution it then examines what is known about aid effectiveness along different links in the causality chain finally it turns to recent trends in the way aid is delivered and the new model that appears to be emerging

the effect of broadband on european union trade a regional spatial approach the positive effect of information and communication technologies ict on trade between countries has been widely studied in the literature but how ict impacts regional trade is limited due to the lack of regional trade data in this paper we test whether broadband as a proxy for ict increases bilateral trade at the regional level in europe we use a novel regional trade database of european union regions and estimate an origin destination flow gravity model for 2007 and 2010 accounting for spatial dependence among trade flows our results indicate that broadband is positive and significant in explaining trade patterns between european regions during both time periods

first peoples lost determining the state of status first nations mortality in canada using administrative data we present the most comprehensive set of estimates to date for status first nations mortality in canada we use administrative data from indigenous and northern affairs canada to establish a set of stylized facts regarding status first nations mortality rates from 1974 to 2013 between 2010 to 2013 the mortality rates of status first nations men and boys are highest in nearly all age groups considered with the exception of status girls between the ages of 10 to 14 on reserve status boys between the ages of 15 to 19 have mortality rates nearly four times that in the general population while status girls between the ages of 15 to 19 have mortality rates five times that in the general population we demonstrate substantial regional variation in mortality rates which are correlated with economic factors we document that there has been no improvement in mortality among status women and girls living on reserve in the last 30 years and relative mortality rates for all status people on reserve has not changed in 40 years mortality rates may be worsening among some age groups jel classification j15 j16 i15 i14

aid dutch disease and manufacturing growth abstract we examine the effects of aid on the growth of manufacturing using a methodology that exploits the variation within countries and across manufacturing sectors and corrects for possible reverse causality we find that aid inflows have systematic adverse effects on a country s competitiveness as reflected in the lower relative growth rate of exportable industries we provide some evidence suggesting that the channel for these effects is the real exchange rate appreciation caused by aid inflows we conjecture that this may explain in part why it is hard to find robust evidence that foreign aid helps countries grow

the size and structure of native white wage differentials in canada the labor market behavior of aboriginal canadians has been little studied by economists this paper establishes some basic empirical regularities concerning the wages of natives in canada applying techniques drawn from the earnings function literature to the statistics canada 1986 census public use sample tape the raw wage gap between aboriginal and white canadians is relatively small compared with that of other disadvantaged groups in north america and it is smaller for women than for males differences in observable characteristics such as education language and region account for as much as 50 percent of the overall white native wage gap

institutions and concentration abstract in a new dataset of 1 3 million firms from over 100 countries i establish a number of regularities in cross country differences in economic concentration concentration of sales and employment is substantially higher in smaller countries and in less developed countries these two factors alone explain roughly half the cross country variation in concentration nevertheless a number of institutional factors offer additional explanatory power for concentration concentration is higher in countries with higher entry costs for new firms in countries with weaker antitrust policy in countries with less financial development in countries with weaker rule of law and in countries with more burdensome regulation weak institutions are associated with higher concentration especially in industries that do not have naturally high levels of concentration in addition the relationships between institutions and concentration are more pronounced in nontradable and investment intensive industries suggesting that natural barriers to competition facilitate the monopolization of sectors especially when institutions are weak

aid and growth what does the cross country evidence really show abstract we examine the effects of aid on growth in cross sectional and panel data after correcting for the possible bias that poorer or stronger growth may draw aid contributions to recipient co

trade policy trade costs and developing country trade this paper briefly reviews new indices of trade restrictiveness and trade facilitation that have been developed at the world bank the paper also compares the trade impact of different types of trade restrictions applied at the border with the effects of domestic policies that affect trade costs based on a gravity regression framework the analysis suggests that tariffs and non tariff measures continue to be a significant source of trade restrictiveness for low income countries despite preferential access programs this is because the value of trade preferences is quite limited a new measure of the relative preference margin developed in the paper reveals that this is very low for most country pairs most countries with very good duty free access to a market generally have competitors that have the same degree of access the empirical analysis suggests that measures to improve logistics performance and facilitate trade are likely to have the greatest positive effects in expanding developing country trade increasing the trade impacts of lowering remaining border barriers by a factor of two or more

aid for trade and greenfield investment summary the aid for trade aft initiative was launched in 2005 at the hong kong ministerial conference where high income countries pledged to increase their aft contributions to developing countries aft comprised almost entirely of aid for trade related infrastructure and building productive capacity would promote growth by easing supply side constraints and improving transportation energy and communication infrastructure by lowering costs of operating in recipient countries aft may increase both trade and investment most research on the effects of aft on international transactions focuses on trade the sparse research on investment investigates aid and net foreign direct investment flows based on the international balance of payments we contribute to the literature by assessing aft effects on new greenfield investment using bilateral data for 25 donor and 120 recipient countries for the period 2003 13 we find that bilateral aft promotes greenfield investment our preferred specification includes bilateral and country time fixed effects and employs the poisson pseudo maximum likelihood ppml estimator robust effects emerge between the top five donors and more developed recipient countries cases where aid flows are large thus we see evidence that a critical level of aid is required to encourage greenfield investment both aid for infrastructure particularly transportation and energy and building productive capacity are found to exert strong effects to the extent that greenfield investment creates jobs and generates technology transfer it appears that aft is accomplishing its development objectives at least with regard to the more advanced recipient countries
