david pearce and the economic valuation of biodiversity david pearce was a pioneer in the economic valuation of biodiversity his work powerfully influenced both later economists who worked in the field and natural scientists and practitioners who gained and appreciation of the importance of economics to their efforts pearce often applied the paradigm of demonstration followed by appropriation the values of biodiversity must first be demonstrated to those who make decisions concerning its survival and then appropriated by them the later step will be possible when market and policy failures are rectified so as to allow the realization of conservation values while pearce wrote extensively on these themes he was also acutely aware of the limitations of the paradigm rosy projections of values that could not be realized and appropriated would be of little practical use and pearce often cautioned against excesses of optimism yet he also clearly believed that there are compelling if not always easily demonstrated reasons for conservation i argue in this paper that pearce s seminal work on the valuation of biodiversity cannot be understood without some appreciation of his philosophical perspective pearce would have described himself as a pragmatist however his pragmatism was grounded in the belief that it is both expedient and ethical to recognize that communities in some of the poorest corners of the world will only conserve biodiversity if they are justly compensated for the sacrifices they must make to do so

trade openness tax reform and tax revenue in developing countries this article investigates empirically whether the effect of tax reform involving the progressive replacement of trade tax revenue with domestic tax revenue in developing countries tax revenue performance measured by tax revenue to gdp ratio depends on the degree of trade openness of these countries the analysis has used an unbalanced panel data set of 95 developing countries over the period 1981 2015 and the two system gmm approach results suggest that tax reform is positively and significantly associated with tax revenue performance in developing countries with the magnitude of this positive effect increasing as countries experience a higher development level additionally and more importantly countries that further open up their economies to international trade enjoy a higher positive effect of tax reform on tax revenue than countries that experience a lower degree of trade openness therefore these findings should help dissipate the concerns of policymakers in developing countries that greater openness to international trade would further erode their tax revenue including by lowering their international trade tax revenue in fact the implementation of an appropriate tax reform in the context of greater trade openness would generate higher tax revenue while concurrently allowing countries to reap the well known benefits of international trade

allocative efficiency in simulated multiple unit combinatorial auctions with quantity support abstract we study the behavior of the quantity support mechanism a support tool which suggests new bids for bidders in semi sealed bid combinatorial auctions the support tool gives bidders a shortlist of provisionally winning bids price quantity combinations they can choose from we conducted a series of simulations to test the efficiency of the final allocations in the auctions our results indicate that quantity support auctions are more efficient than auctions without it although the theoretical optimum is not always reached also in our experiments quantity support auctions led to a lower total cost to the buyer than non combinatorial auctions where the items were auctioned individually the simulation results also show that the qsm cannot entirely overcome the threshold problem and what we call the puzzle problem

foreign direct investment and the dark side of decentralization countries differ in their government architecture some countries are characterized by a high degree of concentration of fiscal administrative judicial executive and lawmaking powers whereas others have decentralized many functions and responsibilities of government to different jurisdictions and various levels of government the cross country differences in the organization of government are also not static but have been subject to substantial change in many countries the co existence of different organizational patterns of government has created an important debate regarding the determinants of particular government structures as well as questions regarding the optimality of different forms of organization

public procurement with unverifiable quality the case for discriminatory competitive procedures unverifiable quality may affect the enforcement of procurement contracts even when the award procedure is able to select the most efficient firm in the market in this paper we show that a discriminatory competitive mechanism which awards the contract on the basis of price and firms past performance yields an efficient allocation of the contract and allows the buyer to implement her desired quality quality enforcement arises out of relational contracting whereby the buyer handicaps a contractor in future competitive tendering processes if it fails to provide the required quality we study an infinitely repeated procurement model with two firms and one buyer imperfectly informed on the firms cost in which in each period the buyer runs a discriminatory auction we restrict our analysis to the case of a buyer committed to her handicapping strategy a case which captures some of the features of a public buyer when players use either grim trigger or stick and carrot strategies we find that the buyer can induce the delivery of optimal unverifiable quality with a variety of handicap levels and when applicable durations of the punishment period for some values of the handicap and the length of the punishment period both firms remain active in the market even when punished

paradoxes in biodiversity conservation biodiversity is important for human wellbeing but it is declining measures to conserve biodiversity are essential but may be a waste of effort if several paradoxes are not addressed the highest levels of diversity are in nations least able to practise effective conservation the flow of funds to international biodiversity conservation appears trivial when compared to the scale of biodiversity loss international agreements may not actually protect or conserve more than what would have been conserved anyway protected areas may be paper parks protected in name but not in practice the very act of protection may contain self destructive features because local communities can easily suffer loss of income and assets making them unwilling partners in the act of protection in turn this places the protected area at risk and may also divert unsustainable harvesting activities to non protected but equally diverse ecosystems in tackling these issues the real biodiversity challenge is redesigning conservation effort making it truly additional and making it compatible with poverty reduction

is trade good or bad for the environment sorting out the causality we seek to contribute to the debate over globalization and the environment by asking what is the effect of trade on a country s environment for a given level of gdp we take specific account of the endogeneity of trade using exogenous geographic determinants of trade as instrumental variables we find that trade tends to reduce three measures of air pollution statistical significance is high for concentrations of so2 moderate for no2 and lacking for particulate matter although results for other environmental measures are not as encouraging there is little evidence that trade has a detrimental effect on the environment

trade surpluses and life cycle saving behaviour abstract the national income account identity and the life cycle theory of consumption together imply that the current account should be a function of the age structure a country with a high proportion of young and retired should have current account deficits using a panel of 84 countries we find empirical support for this hypothesis

capital flows to the new world as an intergenerational transfer the late nineteenth century saw international mass migrations of capital and labor from the old world to the new factors chased each other and the abundant resources at the frontier demographic structure also contributed to the massive capital flows from britain to the new world the dependency hypothesis is confirmed by estimation of savings functions in three new world economies argentina australia and canada in which high dependency rates may have significantly depressed domestic savings rates and pulled in foreign investment in effect an intergenerational transfer from old savers in the old world to young savers in the new

the long run relationship between openness and government size evidence from bounds test the bounds test is applied to determine the existence of a level relationship between government size openness terms of trade volatility and external risk using time series data from australia canada england norway sweden and the usa bounds test results show that the existence of a long run relationship in the usa and canada but not in any of the other countries long run parameters are estimated using both autoregressive distributed lag and fm ols procedures results vary from country to country with some evidence that government size is significantly affected by openness and terms of trade volatility however contrary to argument and evidence developed using cross section data empirical evidence presented in this paper show that the size of the government has not changed to mitigate the effect of increased income risks associated with greater openness

the design of multidimensional auctions procurement auctions usually require the bid to specify several characteristics of the contract to be fulfilled in this article i study the design of such mechanisms allowing for a special case of correlation of the firm s costs i describe the properties of optimal mechanisms and study the design of multidimensional auctions contrary to the independent costs model to implement the optimal outcome the procurer will need to use a two stage auction in the first stage the procurer selects one firm in the second stage he bargains to readjust the level of quality to be provided

the variable rate of growth effect in the life cycle saving model the rate of growth in real gnp g affects the aggregate saving rate positively in life cycle saving models this rate of growth effect is invariably estimated as the coefficient of g in the saving function we show that other determinants of the saving rate influence the rate of growth effect in other words the rate of growth effect is not constant specifically the real rate of return on financial assets and the population dependency ratio determine the timing of saving over the life cycle and hence alter the rate of growth effect the dependency ratio also has an effect on the saving rate which is independent of g because it together with the foreign saving rate determines the level of saving over the life cycle

miracles and debacles in defence of trade openness the central theme of this paper is that sustained rapid growth cannot be achieved without rapid growth in trade a review of the experience during the past four decades offers virtually no examples of countries achieving sustained rapid growth called miracles in this paper without simultaneously experiencing sustained rapid growth in trade in the presence of low or high but declining barriers to trade simultaneously the claim that opening to trade leads to sustained income losses is unfounded a review of the experience of the countries that have faced stagnation or declining per capita incomes on a long term basis called debacles in this paper reveals no connection to a sustained surge in imports

openness and inflation a new assessment romer 1993 uses a barro gordon type model to argue that openness puts a check on the government s incentive to engage in unanticipated inflation because of induced exchange rate depreciation 2 therefore in the absence of precommitment in monetary policy more open economies will tend to have lower inflation rates romer finds that empirically over a large sample of countries and over a broad time frame average inflation rates are lower in smaller more open economies this relationship is significant quantitatively large and robust moreover these findings suggest that models in which the absence of precommitment in monetary policy leads to inefficiently high average levels of inflation are essential to understanding inflation in most of the world this comment suggests that the negative link between inflation and openness romer found may be largely driven by the responses of severely indebted countries sics to the debt crisis of the 1980s figures i and ii show the scatterplots of the logarithms of average inflation and openness for the subperiods 1973 to 1981 predebt crisis and 1982 to 1990 the debt crisis period different groups of countries are separated according to their indebtedness level 3 the solid lines in the figures represent the predicted value of inflation obtained from a regression of openness on inflation for the countries in each group as the scatterplots show there is indeed a strong negative relation between openness and inflation among sics during the debt crisis

who cares about biodiversity optimal conservation and transboundary biodiversity externalities the convention on biological diversity s 2010 target to reduce the rate of biodiversity loss was achieved by very few countries why we use the theory of conservation implicit in the hotelling model of non renewable resource pricing to analyze the problem distinguishing between the benefits to countries where conservation takes place and to other countries we estimate models for three taxonomic groups and find that while individual countries value conservation within their borders in poor countries this effect is dominated by the negative impact of income growth international concessional financial contributions to conservation in poor countries are found to be statistically insignificant we conclude that countries care about the biodiversity within their national borders but only when development priorities permit and only when it becomes scarce enough that its value grows more rapidly than the return on alternative assets there is little evidence that high income countries yet care sufficiently about biodiversity in the places where it is most threatened to affect conservation outcomes there

a reexamination of the role of income for the trade and environment debate recent work on the relationship between international trade and the environment has found small but negative effects of increased openness on measures of pollution for the average country on a panel of 128 countries it is shown that like previous studies the trade intensity effect is negative and significant for the average country for emissions of four localized pollutants so2 nox co and vocs however trade intensity effects are not uniform across countries of different income levels in fact a strong non monotonicity exists in trade intensity elasticities it is found that countries with relative world incomes less than 0 5 or greater than 2 5 tend to have positive trade intensity elasticities while countries with relative world incomes between 0 5 and 2 5 tend to have negative trade intensity elasticities the results imply that both factor abundance and pollution haven effects may be at work but that the dominance of one effect over the other depends on a country s level of development

globalisation and values this paper discusses a central element in globalisation debate little addressed by economists namely the interactions at global national and community levels between globalisation and societally based values social values refer to wider notions of collective identity religious values attitudes towards materialism moral beliefs and a sense of collective awareness and are a broader and more encompassing concept than social capital discussed in recent economics and sociology literature social capital relates to trust honesty and the social fabric of accepted norms central to the successful implementation of individual optimising decisions and denotes a communal asset reflecting strength of joint collective commitment whose amount can be increased or improved upon through investment of time and resources social values are much discussed in sociological literature going back to comte durkheim parsons and others the issues taken up here are how different social values might interact and change as societies and their economies integrate globalise processes of value competition displacement and joint assimilation occur naturally to economists but seem little studied by sociologists who seemingly place less stress on analytical comparative statics scenarios for how values can interact under globalisation are discussed in the text

what might globalisation s critics believe critics of globalisation object to many things some of which can be easily understood within standard economic models but others of which seem to reflect a view of the world that economists generally do not share this paper attempts to identify several alternative frameworks for analysis within which some of their criticisms may be understood with the ultimate aim of extracting testable implications that differ from standard models three such alternative models are suggested all of which focus mainly on the behaviour of owners and managers of corporate capital an anti labour model in which capitalists are willing to sacrifice some of their own profits for the chance to make labour worse off a labour monopsony model in which capitalists co operate globally to increase profits by depressing wages and an international political economy model in which capitalists use their resources to influence the political process for more than just obtaining import protection this third framework which is not spelled out in any detail here has capitalists seeking policies such as export subsidies and other means of promoting market access and it also has them influencing the international negotiations that set the rules of international agreements and organisations such as the nafta and wto examples of the latter sort of influence are discussed

trade openness and environmental quality international evidence we examine the relationship between trade openness and the environment in a cross country panel using the emission of particulate matter pm10 as the basic indicator of environmental quality the panel cointegration test results show a long run relationship between particulate matter emissions trade openness and economic growth we find that increased trade openness leads to environmental degradation for the global sample however the results differ according to the income of countries trade openness has a benign effect on the environment in high income countries but a harmful effect in middle and low income countries these results are generally robust to different measures of trade openness and environmental quality interestingly and significantly the results are consistent with the popular notion that rich countries dump their pollution on poor countries finally we find evidence of a feedback effect between trade openness and particulate matter emissions for the global sample as well as different income groups of countries

age structure and inflation a wicksellian interpretation of the oecd data wicksell s cumulative inflation process is founded on the separation of investment and saving decisions the demographic age structure influences the aggregate of both these decisions and therefor

design competition through multidimensional auctions this article studies design competition in government procurement by developing a model of two dimensional auctions wherefirms bid on both price and quality and bids are evaluated by a scoring rule designed by a buyer three auction schemes first score second score and second preferred offer are introduced and related to actual practices if the buyer can commit to a scoring rule in his best interest the resulting optimal scoring rule underrewards quality relative to the buyer s utility function and implements the optimal outcome for the buyer underfirst and second score auctions absent the commitment power the onlyfeasible scoring rule is the buyer s utility function under which 1 all three schemes yield the same expected utility to the buyer and 2 first and second score auctions induce the first best level of quality which turns out to be excessive from the buyer s point of view

do more open economies have bigger governments another look abstract we reconsider the evidence of a positive relationship between openness and the size of government recently established by rodrik rodrik d 1998 why do more open economies have bigger governments journal of political economy 106 997 1032 and others while the existing literature focuses on expenditure based measures of government we consider non budgetary measures such as government ownership of enterprises price controls asset expropriation each of these may have little impact on government expenditures yet can make the role of government sizable we demonstrate that the scope of government is much larger in less open economies when considering non budgetary measures additionally we show that higher levels of non budgetary government are positively correlated with trade barriers finally we provide further evidence on the hypothesis that larger governments provide social insurance in open economies subject to terms of trade shocks although we find that greater terms of trade risk is weakly associated with larger government in all forms these interventions include price controls and greater risk of asset expropriation which are hard to reconcile with a pure insurance motive

multinational oil companies and the adoption of sustainable development a resource based and institutional theory interpretation of adoption heterogeneity sustainable development is often framed as a social issue to which corporations should pay attention because it offers both opportunities and challenges through the use of institutional theory and the resource based view of the firm we shed some light on why more than 20 years after sustainable development was first introduced we see neither the adoption of this business model as dominant nor its converse that is the total abandonment of the model as unworkable and unprofitable we focus on multinational corporations mncs because they were among the organizations first called to take action in order to illustrate the institutional pressures mncs face and their strategic response to these pressures we analysed four major oil and gas multinationals subject to similar sustainable development pressures climate change biodiversity renewable energy development and social investment we argue that normative and coercive isomorphism does not occur at the global level because sustainable development is largely a stakeholder driven rather than a broad social pressure that is host country interpretation of sustainable development pressures varies across an mnc s subsidiary network based on the analysis of the four major mncs annual reports from 2000 to 2005 we argue that mimetic isomorphism may occur but since it implies the use of complex and intangible resources mimetic processes are slow rare and discretionary

openness country size and government size additional evidence from a large cross country panel abstract a body of influential research has suggested that there is a negative association between country size and government size and between country size and openness and these may account for the positive association between openness and government size estimation of several models from 41 year panel data for over 150 countries indicates that while pooled ols estimates support the foregoing scenario when cross country heterogeneity is taken into consideration through the fixed effects format there is little evidence of a negative association of country size with either government size or openness therefore it does not seem likely that positive association between openness and government size arises due to the mediating role of country size

why nations become wealthy the effects of adult longevity on saving we analyze steady state and out of steady state effects of the transition in adult longevity on the national saving rate using historical data and international panel data the rise in adult life expectancy has a large and statistically significant effect on aggregate saving the effects have been especially pronounced in east asia because its mortality transition was very rapid gains in life expectancy are much more important than declines in child dependency population aging may not lead to lower saving rates in the future if life expectancy and the duration of retirement continue to increase

openness inflation and the phillips curve a puzzle models of open economies with nominal rigidities are often thought to predict a correlation between openness to trade and the slope of the output inflation trade off or phillips curve using a variety of measures of the trade off and a standard measure of openness this paper argues that the direct evidence for a correlation is not strong in turn this calls into question the usual explanation for the negative correlation between openness and inflation that was documented by romer 1993 the paper considers some alternative explanations for the romer evidence

ecosystem services as substitute inputs basic results and important implications for conservation policy abstract in recent decades conservation advocates have often emphasized the contributions of ecosystem services to the production of other products a demonstration of the value of ecosystems as inputs into production would motivate their conservation such arguments often offer the observation that ecosystem services can substitute for purchased inputs and thus reduce costs if this is true however it has another important implication a producer who is preserving local ecosystems so as to maximize her own profit will produce less output if she further increases her reliance on ecosystem services this may induce leakage by which one producer s greater reliance on ecosystem services indirectly motivates others to preserve fewer natural ecosystems i demonstrate this result in a simple but canonical model and calibrate my findings to a celebrated example to show they could be quantitatively significant my results suggest another reason that appeals to ecosystem services as a motivation for conservation should be made with care at the most basic level they emphasize the importance of being clear about what we mean by conservation do we want to save some diversity in many places or nearly all indigenous diversity in a few places

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

homework in development economics household production and the wealth of nations we introduce home production into the neoclassical growth model and examine its consequences for development economics in particular we study the extent to which one can account for international income differences with differences in policies that distort capital accumulation in models with home production such policies not only reduce capital accumulation but also change the mix of market and nonmarket activity hence these models can generate larger differences in output than standard models for a given policy differential we also show how the welfare implications change when we incorporate home production

the rise of china and east asian export performance is the crowding out fear warranted this paper examines how china s emergence as a major trading nation is affecting export performance of its east asian neighbours following a stage setting overview of trends and patterns of china s export performance it probes china competition in third country markets and emerging patterns of imports the east asian export experience is examined in a wider global context against the backdrop of the ongoing process of global production sharing the findings indicate that the china threat has been vastly exaggerated in the contemporary policy debate china s rapid market penetration in traditional labour intensive manufactured goods has occurred mostly at the expense of the high wage east asian countries without crowding out the export opportunities of low wage countries in the region more importantly china s rapid integration into global production networks as a major assembly centre has created new opportunities for the other east asian countries to engage in various segments of the value chain in line with their comparative advantage

demography national savings and international capital flows this paper addresses the relationship between age distribution national savings and the current account balance the results point to substantial demographic effects with increases in both the youth and old age dependency ratios associated with lower savings rates they also point to differential effects on savings and investment and thus to a role for demography in determining the current account balance the estimated demographic effect on the current account balance exceeds 6 percent of gdp over the last three decades for a number of countries and given expected demographic trends is likely to be substantially larger over the coming decades copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

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

welfare effects of global patent protection this paper uses a simple model of invention and patent protection to examine the welfare effects of extending patent protection from the country where invention takes place to another country that is only a consumer of invented products it is shown that while the welfare of the inventing country certainly rises with the extension of patent protection that of the other country probably falls and may well fall by more than the increase in welfare of the inventing country in particular as patent protection is extended to a larger and larger portion of the world the effect on the welfare of the world as a whole of extending it to the rest of the world becomes negative

age structure and trade openness an empirical investigation this study focuses on the relationship between age structure and trade openness we hypothesise that a higher share of the working age population in the total population increases trade openness because the dependent population tends to spend more than the working age population on non tradable goods such as education and medical services we estimate the effects of age structure on trade openness using panel data for 85 countries from 1991 to 2010 the empirical results show that the share of the working age population has a positive effect on trade openness an increase in the share of the working age population is considered to be one factor that contributed to an increase in trade openness in the sample period

debt dependence and the demographic transition latin america in to the next century abstract in the decades ahead world demographic trends indicate that our planet s share of the population of working age will be gradually diminishing the regional incidence of the trends however shows a marked bias thus the general equilibrium of the world saving investment nexus may be fundamentally realigned in the years to come via dependency effects for example favorable demographic prospects in latin america and elsewhere in the developing world offer poorer countries the chance to use the potential of their own demographic transitions to propel financial transitions to domestically financed accumulation even capital export

sealed bid auction of netherlands mussels statistical analysis this article presents an econometric analysis of the many data on the sealed bid auction that sells mussels in yerseke town the netherlands the goals of this analysis are obtaining insight into the important factors that determine the price of these mussels and quantifying the performance of an individual purchase manager besides a case study the article is a general study on the role of auctions in supply chains and on hedonic price factors

trade openness and government size abstract we examine whether trade openness influences government size using panel data we find no evidence of a positive relationship rather causality tests show that larger government size leads to lower openness the opposite of what rodrik rodrik dani 1998 why do more open economies have bigger governments journal of political economy 106 997 1032 hypothesized

multi criteria auctions without full comparability of bids the emergence of auction mechanisms that support bids characterized by several attributes is one of the most recent evolutions within auction theory these mechanisms referred to as multi attribute multiple issue or multi dimensional auctions are at the intersection between multi criteria decision and auction theories the purpose of this paper is to introduce multi criteria auctions the originality of which is not to require full comparability between bids we claim that this distinctive feature is of great interest especially in procurement situations furthermore the existence of potential incomparability between multi dimensional offers will permit us to manage different bidding niches coexisting within the same bidding space a theoretical framework based on a general preference structure will be introduced and then referenced to existing approaches such as multi attribute auctions or new ones such as dominance based multi criteria auctions or butterfly auctions

a structural decomposition of the u s trade balance productivity demographics and fiscal policy abstract the us external deficits have been the most striking manifestation of global imbalances this paper investigates the contribution of productivity growth demographics and fiscal policy in accounting for the evolution of the us external imbalances against industrialized countries during the last three decades productivity growth plays a dominant role demographics explain a non negligible and nearly permanent component of the us trade deficit furthermore the international demographic transition is crucial for large us external imbalances to be consistent with the persistent decline of world real interest rates observed in the data fiscal policy is of minor importance

should patent protection be extended to all developing countries he uruguay round has extended the scope of gatt multilateral trade negotiations well beyond the tariffs that had occupied most previous negotiations in addition to various non tariff barriers which had also been dealt with to a degree in the tokyo round as discussed in deardorff and stern 1983 and 1986 the uruguay round dealt with issues of trade in services international investment and intellectual property since these new issues have conceptually quite different characteristics than the tariffs of previous negotiations it is appropriate to examine them afresh to determine whether the objectives of the uruguay round negotiations can be considered economically sound this paper describes such an analysis for a particular aspect of the intellectual property negotiations patent rights and in the process voices some skepticism about this aspect of the uruguay round s objectives inclusion of trade related intellectual property issues or trips in the uruguay round agenda was done largely at the insistence of the united states firms in the united states have long been concerned that their position at the cutting edge of technological progress was being eroded by unauthorised copying of their intellectual property elsewhere in the world while export of such copied products back into the united states might be restricted under us law this would provide little help in competition with the pirate firms in third country markets

a trading mechanism contingent on several indices we introduce a trading mechanism where the execution of an order on a security can be made contingent on the relation between the clearing price of the security and the clearing price of one or several indices a mechanism similar to ours but limited to only one index was implemented on the tel aviv stock exchange we argue that it is in some cases crucial to make the execution of an order contingent on several indices our mechanism consists of a particular implementation of a double sided multi unit combinatorial auction with substitutes or dmcs auction which we introduced in an earlier article

openness country size and government abstract this paper shows that smaller countries have a larger share of public consumption in gdp and are also more open to trade these empirical observations are consistent with recent theoretical models explaining country formation and break up and may account for the observed positive empirical relationship between trade openness and government size

models for iterative multiattribute procurement auctions multiattribute auctions extend traditional auction settings to allow negotiation over nonprice attributes such as weight color and terms of delivery in addition to price and promise to improve market efficiency in markets with configurable goods this paper provides an iterative auction design for an important special case of the multiattribute allocation problem with special preferential independent additive structure on the buyer value and seller costs auction additive discrete provides a refined design for a price based auction in which the price feedback decomposes to an additive part with a price for each attribute and an aggregate part that appears as a price discount for each supplier in addition this design also has excellent information revelation properties that are validated through computational experiments the auction terminates with an outcome of a modified vickrey clarke groves mechanism this paper also develops auction nonlinear discrete for the more general nonlinear case a particularly simple design that solves the general multiattribute allocation problem but requires that the auctioneer maintains prices on bundles of attribute levels

trade openness foreign direct investment and child labor summary the skeptics of globalization argue that increased trade openness and foreign direct investment induce developing countries to keep labor costs low for example by letting children work this article argues that there are good theoretical reasons why globalization might actually have the opposite effect we test this with various measures of child labor and provide the first analysis of foreign investment in addition to trade we present evidence that countries that are more open to trade and or have a higher stock of foreign direct investment also have a lower incidence of child labor this holds for the labor force participation rate of 10 14 year old children the secondary school nonattendance rate and a count measure of economic sectors with child labor incidence as the dependent variables globalization is associated with less not more child labor

reverse auction with buyer supplier negotiation using bi level distributed programming this study presents a framework for solving a sealed bid multi issue and multi sourcing reverse auction problem in which negotiation takes place between the buyer and the suppliers during the bidding process the problem is formulated as a bi level distributed programming model in which the buyer is the upper level decision maker while suppliers at the lower level make decisions independent of each other the negotiation process between the buyer and the suppliers is facilitated via the iterative exchange of decision information between the upper and lower levels of the model the outcome of the sealed bid auction is determined using an algorithm designed to establish the optimum quantity allocation and delivery time at the upper level and the corresponding optimized production plans at the lower level the feasibility of the proposed approach is demonstrated via an illustrative example

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

global estimates of pro poor growth summary the main objective of the present paper is to present a cross country analysis of pro poor growth in 80 countries in 237 growth spells during the period 1984 2001 to achieve this objective the paper proposes a new measure of pro poor growth that captures gains and losses of growth rates due to changes in the distribution of consumption the gains imply pro poor growth while the losses imply anti poor growth the statistical test carried out in the paper shows that regional location of countries has a significant association with the pro poorness of growth the paper also attempts to test for the association between growth patterns and certain variables that the literature has identified as significant determinants of growth and inequality out of many variables the paper focuses on four namely inflation the share of agriculture in gdp openness to trade and the rule of law

why india lags behind china and how it can bridge the gap though india has been growing at six per cent annually since the late 1980s it trails behind china which has been growing at ten per cent per annum since 1981 the single most important factor explaining this difference is the relatively poor performance of indian industry whereas the share of industry in china s gdp rose from 42 per cent in 1991 to 51 per cent in 2001 it remained virtually stagnant in india by contrast services grew rapidly in india expanding from 42 per cent in 1991 to 48 per cent in 2001 with the information technology sector less than two per cent of the gdp services growth was largely in the informal sector approximately 77 per cent of india s workers live in rural areas to bring a large chunk of this workforce into the modern sector india must achieve a much higher growth in the traditional unskilled labour intensive industry growth in the information technology sector gives india an extra lever but cannot be the main engine of transformation therefore the right approach is to walk on two legs traditional labour intensive industry and the modern it industry both legs need strengthening through further reforms the paper suggests four specific reforms three for industry and one for it necessary to achieve the transformation to a modern economy

the environmental consequences of trade evidence from subnational trade flows abstract the debate over the environmental consequences of free trade is not only quite heated but also entails significant policy ramifications recently cross sectional analysis at the country level has made use of exogenous determinants of trade to identify the causal effect of trade on the environment finding moderate evidence of a beneficial impact of expanded trade on environmental quality given the stakes involved we revisit this finding using subnational data on trade flows across us states and several measures of pollution not only does the analysis shed further light on the debate at the international level but also addresses a heretofore unexamined question does greater inter regional commerce at the subnational level harm the environment our findings are striking providing further evidence against a negative environmental impact of trade for the majority of measures analyzed however several sources of heterogeneity arise that are noteworthy

competitive bidding in asymmetric multidimensional public procurement abstract in a multidimensional procurement auction such as a most economically advantageous tender asymmetric opponents with different cost structure and predetermined quality compete for the highest score which combines price and quality production inefficiency characterizes each tenderer we derive the equilibrium equations and boundary conditions for which closed form solutions are not available we compare the bidding behavior of any pair of rival tenderers and demonstrate that equilibrium prices critically depend on the comparison of the cost difference c with respect to the increment of score attribute s for the same production inefficiency a tenderer with a relatively higher c compared to s stands in weak competitive position and is forced to bid more aggressively we show how the opposing advantage of each bidder with respect to cost or score attribute induces the extent of competition under a different perspective we analyze bidding by a pair of tenderers for a given maximum score achieved when pricing is at cost our analysis reveals that the player with consistently higher percentage change of the probability of being more efficient than the rival is in a disadvantageous position and receives lower score in the awarding process our results are useful for tenderers in assessing their competitive position the findings enable contracting authorities to evaluate competition at the preliminary stage of design and to examine the effects of the awarding criterion on pricing

auctions and bidding a primer maybe the contractor was right to think bid jobs are different but it is more likely that he suffered from too simple a view of what is involved in preparing a competitive bid our analysis will show that even an experienced estimator working in familiar terrain can lose money if he doesn t understand the subtleties of competitive bidding the phenomenon experienced by the painting contractor known as the winner s curse is just one of the surprising and puzzling conclusions that have been turned up by modern research into auctions another is the theoretical proposition supported also by some experimental evidence that for example a sealed bid treasury bill auction in which each buyer pays a price equal to the highest rejected bid would yield more revenue to the treasury than the current procedure in which the winning bidder pays the seemingly higher amount equal to his own bid there are also subtle results that demonstrate the equivalence of such apparently different institutions as the standard sealed bid auction in which the auctioneer seller sells the goods to the highest bidder for a price equal to his bid and the dutch auction in which the auctioneer seller begins by asking a high price and gradually lowers the price until

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

trade reform with quotas partial rent retention and tariffs quotas are the predominant means of protection in developed countries with quota rents commonly shared between exporter and importer this paper derives shadow prices appropriate to evaluating trade reform under these circumstances and provides a number of useful sufficient conditions for welfare improving piecemeal reform in doing so the authors apply the distorted quantity constrained expenditure function and use implicit separability to derive more powerful results than have previously been available

a new measure of trade openness trade openness popularly measured as x m gdp in the hundreds of studies published to date consistently considers the world s biggest trading countries such as the usa the uk japan and germany to be closed economies irrespective of the data set used this study suggests a composite trade share measure that more completely reflects reality by combining two important dimensions of trade openness trade share and the relative importance of a country s trade level to total world trade robustness tests support the new proposed measure in lieu of the conventional measure of openness and suggest that the latter may not only be incomplete but may also overstate the impact of trade on such things as income and the environment

the higher educational transformation of china and its global implications this chapter documents the major transformation of higher education that has been underway in china since 1999 and evaluates its potential global impacts this has involved major new resource commitments to tertiary education and significant changes in organizational form reflecting china s commitment to continued high growth through quality upgrading and the production of ideas and intellectual property as set out in both the tenth 2001 2005 and eleventh 2006 2010 five year plans the number of undergraduate and graduate students in china has been growing at approximately 20 per year since 1999 and the total number of graduates at all levels of higher education in china has increased by more than a factor of six in the last decade entering class sizes and total student enrolments have risen fast too approximately quintupling prior to 1999 increases in these areas were much smaller much of the increased spending is focussed on elite universities and new academic contracts differ sharply from earlier ones which lacked tenure and often used annual publication quotas

analyzing online b2b exchange markets asymmetric cost and incomplete information this research applies the discriminating auction to analyze the online b2b exchange market in which a single buyer requests multiple items and several suppliers having equal capacity and asymmetric cost submit bids to compete for buyer demand in the present model we examine the impact of asymmetric cost and incomplete information on the participants in the market given the complete cost information each supplier randomizes its price and the lower bound of the price range is determined by the highest marginal cost in addition the supplier with a lower marginal cost has a larger considered pricing space but ultimately has a smaller equilibrium one than others with higher marginal costs when each supplier s marginal cost is private information the lowest possible price is determined by the number of suppliers and the buyer s reservation price comparing these two market settings we find whether it is beneficial to buyers or suppliers depends on the scale of the bid process and the highest marginal cost when the number of suppliers and the difference between the highest marginal cost and the buyer s reservation price are sufficiently large each supplier can gain a higher profit if the marginal costs are private information on the contrary when the highest marginal cost approaches the buyer s reservation price complete cost information benefits the suppliers

trade liberalization in a multinational dominated industry abstract existing theoretical models in the trade industrial organization literature assume almost exclusively that firms are national enterprises so that there is no international coordination by multinational firms we develop a model in which multinationals compete among themselves but coordinate production pricing and sales decisions across multiple plants and markets free entry and exit is assumed and cases in which the multinationals can and cannot segment markets are considered the model is simulated using data from the north american auto industry results are compared with a counter factual model calibrated to the same data which assumes national ownership of firms

effective response to rfqs and supplier development a supplier s perspective abstract considering multiple attributes while evaluating request for quotes rfqs responses from suppliers is gaining significant importance in industrial procurement while price has traditionally been the most important factor in evaluating rfq responses incorporation of non price attributes such as quality and delivery performance is becoming essential and critical research on multi attribute rfqs has received significant attention in an auction format with models addressing issues relating to auction mechanism design winner determination and auction dynamics primarily from a buyer s perspective there have been few approaches if any that have investigated the issue of response to multi attribute rfqs from a supplier s perspective which is the focus of this paper such an approach will assist a supplier in effectively responding to rfqs thereby maximizing the likelihood of winning future contracts it also indirectly assists in supplier development and helps foster competition among suppliers which benefits both the buyers and the suppliers we develop mathematical models that address this important issue and demonstrate their usefulness through an illustrative dataset

china s economic growth 1978 2025 what we know today about china s economic growth tomorrow summary this paper examines china s future growth prospects and the potential drivers of future growth using two approaches it first asks in how far china s recent economic development matches standard growth patterns identified in development economics and trade theory second gdp is decomposed into income components which in turn are explained for the reform period by the quantity and quality of labor future gdp can then be re composed from future labor data available today overall china s economic growth is likely to continue at current rates through 2015 before it gradually slows such a growth has numerous implications

modeling competitive bidding a critical essay in analyzing bidding modeling matters this paper is a critical analysis of the models available to aid competitive bidding decision making bidding strategy and auction design in real transactions after an introductory overview this paper describes the contexts in which auctions arise reviews the mainstream theory of single isolated auctions and discusses the important work involved in enrichment of this theory in doing so it indicates results that have been obtained and the sort of changes in analytical approach that are needed to tackle other critical enrichments the paper summarizes briefly what is known about the direct use of models by bidders and auction designers a general theme of this paper is that enriched models are needed to bring bidding theory closer to direct applicability in decision making

a multi attribute e auction mechanism for procurement theoretical foundations abstract we describe a multi attribute e auction mechanism with a focus on its theoretical foundations our mechanism is designed for auctioning multiple units of a good primarily in b2b transactions it can be used in various types of forward and reverse auctions rfqs request for quote although the emphasis in this paper is on procurement to incorporate the auction owner s preferences across issues attributes in an auction negotiation setting we adopt a novel application of the pricing out technique another key feature of our mechanism is the optimization based suggested price decision support component which momentarily gives the best price acceptable to the buyer

rfq auctions with supplier qualification screening we consider a manufacturer using a request for quotes rfq reverse auction in combination with supplier qualification screening to determine which qualified supplier will be awarded a contract supplier qualification screening is costly for the manufacturer for example involving reference checks financial audits and on site visits the manufacturer seeks to minimize its total procurement costs i e the contract payment plus qualification costs although suppliers can be qualified prior to the auction prequalification we allow the manufacturer to delay all or part of the qualification until after the auction postqualification using an optimal mechanism analysis we analytically explore the trade offs between varying levels of pre and postqualification although using postqualification causes the expected contract payment to increase bids from unqualified suppliers are discarded we find that standard industrial practices of prequalification can be improved upon by judicious use of postqualification particularly when supplier qualification screening is moderately expensive relative to the value of the contract to the manufacturer

do we really care about biodiversity this paper addresses from an economic perspective the issue of global biodiversity conservation it challenges the perception that the world really cares a great deal about biodiversity and is prepared to pay the full cost of maintaining this stock of natural capital despite the existence of a plethora of international agreements there still seems to be a global deficit of care surrounding efforts to combat challenges such as those posed by global warming and biodiversity conservation more light can be thrown on the degree of care by measuring both the actual expenditures and the stated willingness to pay for biodiversity conservation however actual expenditures are much lower than willingness to pay estimates recorded in the published literature using the criteria that the right amount of conservation effort is one where the marginal economic benefits from conservation just equal the marginal costs of conservation the paper explores the biodiversity conservation conundrum and concluded that on the available evidence the world does not care too much about this natural capital stock and bequests to future generations

fertility and the real exchange rate we use a quinquennial data set covering 87 countries between 1975 and 2005 to investigate empirically the relationship between fertility and the real effective exchange rate theoretically a country experiencing a decline in its fertility rate can be expected to experience a real depreciation we test and confirm this hypothesis controlling for a number of other potential determinants we find a statistically significant and robust link between fertility and the exchange rate our point estimate is that a decline in the fertility rate of one child per woman is associated with a depreciation of approximately 15 in the real effective exchange rate on utilise une base de donnees quinquennales pour 87 pays entre 1975 et 2005 afin d etudier empiriquement la relation entre fecondite et taux de change reel effectif theoriquement un pays qui fait l experience d un declin dans le taux de fecondite peut s attendre a une depreciation reelle on teste et on confirme que c est le cas en controlant un certain nombre d autres determinants potentiels il existe une relation significative et robuste entre fecondite et taux de change un declin du taux de fecondite d un enfant par femme est associea une depreciation d a peu pres 15 dans le taux de change reel effectif

regulating a monopolist with unknown costs we consider the problem of how to regulate a monopolistic firm whose costs are unknown to the regulator the regulator s objective is to maximize a linear social welfare function of the consumers surplus and the firm s profit in the optimal regulatory policy prices and subsidies are designed as functions of the firm s cost report so that expected social welfare is maximized subject to the constraints that the firm has nonnegative profit and has no incentive to misrepresent its costs we explicitly derive the optimal policy and analyze its properties in their classic papers dupuit 2 and hotelling 5 considered pricing policies for a bridge that had a fixed cost of construction and zero marginal cost they demonstrated that the pricing policy that maximizes consumer well being is to set price equal to marginal cost and to provide a subsidy to the supplier equal to the fixed cost so that a firm would be willing to provide the bridge this first best solution is based on a number of informational assumptions first the demand function is assumed to be known to both the regulator and to the firm while the assumption of complete information may be too strong the assumption that information about demand is as available to the regulator as it is to the firm does not seem unnatural a second informational assumption is that the regulator has complete information about the cost of the firm or at least has the same information about cost as does the firm this assumption is unlikely to be met in reality since the firm would be expected to have better information about costs than would the regulator as weitzman has stated an essential feature of the regulatory environment i am trying to describe is uncertainty about the exact specification of each firm s cost function in most cases even the managers and engineers most closely associated with production will be unable to precisely specify beforehand the cheapest way to generate various hypothetical output levels because they are yet removed from the production process the regulators are likely to be vaguer still about a firm s cost function 12 p 684 as this observation suggests it is natural to expect that a firm would have better information regarding its costs than would a regulator the purpose of this paper is to develop an optimal regulatory policy for the case in which the regulator does not know the costs of the firm one strategy that a regulator could use in the absence of full information about costs is to give the firm the title to the total social surplus and to delegate the pricing decision to the firm in pursuing its own interests which would then be to maximize the total social surplus the firm would adopt the same marginal cost pricing strategy that the regulator would have imposed if the regulator had

a time frequency analysis of trade openness and co2 emissions in france abstract the paper explores the comovement between trade openness and carbon dioxide co2 emissions in france over the period 1960 2013 by using the wavelet tool the investigation offers detailed information about this interaction for different sub periods of time and frequencies it also reveals the lead lag nexus between variables under cyclical and anti cyclical shocks the main findings reveal no comovement at high frequency between trade openness and gas emissions confirming the neutral hypothesis on short term the co2 emissions positively drive the trade openness at medium frequency hence on medium term the inexistence of strong environmental rules stimulate the international trade especially the exports obtained based on pollutant capacities curiously the trade openness positively runs the gas emissions at low frequency herein on long term the interaction between trade and co2 emissions is driven by the business cycle

better faster cheaper an experimental analysis of a multiattribute reverse auction mechanism with restricted information feedback the majority of reverse auctions for procurement use a single attribute price format while providing constraints on nonprice attributes such as quality and lead time alternatively a buyer could choose to conduct a multiattribute auction where bidders can specify both a price and levels of nonprice attributes while such an auction may provide higher theoretical utility to the buyer it is not clear that this theoretical improvement will be realized given the increased complexity of the auction in this research we present an ascending auction mechanism for a buyer whose utility function is known and dependent on three attributes motivated by a supply chain procurement problem setting we consider quality and lead time for the two attributes in addition to price the auction mechanism provides the bidders with restricted feedback regarding the buyer s utility function we explore experimentally the performance of this multiattribute auction mechanism as compared to a price only auction mechanism compared with the price only auction we find that our mechanism design is effective in increasing both buyer utility and bidder supplier profits

revenue deficiency under second price auctions in a supply chain setting consider a firm called the buyer that satisfies its demand over two periods by assigning both demands to a supplier via a second price procurement auction call this the standard auction in the hope of lowering its purchase cost the firm is considering an alternative procedure in which it will also allow bids on each period individually where there can be either one or two winners covering the two demands call this the multiple winner auction choosing the multiple winner auction over the standard auction can in fact result in a higher cost to the buyer we provide a bound on how much greater the buyer s cost can be in the multiple winner auction and show that this bound is tight we then sharpen this bound for two scenarios that can arise when the buyer announces his demands close to the beginning of the demand horizon under a monotonicity condition we achieve a further sharpening of the bound in one of the scenarios finally this monotonicity condition allows us to generalize this bound to the t period case in which bids are allowed on any subset of period demands

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

a smart market for industrial procurement with capacity constraints we address the problem of designing multi item procurement auctions for a monopsonistic buyer in capacity constrained environments using insights from classical auction theory we construct an optimization based auction mechanism smart market relying on the dynamic resolution of a linear program minimizing the buyer s cost under the suppliers capacity constraints suppliers can modify their offers in response to the optimal allocation corresponding to each set of bids giving rise to a dynamic competitive bidding process to assist suppliers we also develop a bidding suggestion device based on a myopic best response mbr calculation that solves an associated optimization problem assuming linear costs for the suppliers we study within a game theoretic framework the sequence of bids arising in this smart market under a weak behavioral assumption and some symmetry requirements an explicit upper bound for the winning bids is established we then formulate a complete behavioral model and solution methodology based on the mbr rationale and show that the bounds derived earlier continue to hold we analytically derive some structural and convergence properties of the mbr dynamics in the simplest nontrivial market environment which suggests further possible design improvements and investigate bidding dynamics and incentive compatibility issues via numerical simulations
