using genuine savings for climate policy evaluation with an integrated assessment model there has been a recent increase in efforts to develop broader models to assess the impact of climate change and climate change policies both in terms of impact measures beyond gdp and in terms of modelling complexity beyond dice rice models climate policies aimed at reducing co2 emissions can have impacts in multiple sectors of the economy and can change consumption levels over time we show how the sustainability indicator genuine savings can be endogenised within a general equilibrium model and used as a criterion for judging the impacts of such policies in terms of future well being differences in genuine savings rates between co2 emission reduction scenarios are discussed we show how a broader genuine savings based assessment of climate change can result in a re evaluation of the consequences and costs of inaction in terms of various climate change related policies and how multiple environmental and well being outcomes can be analysed within a unified modelling framework

testing genuine savings as a forward looking indicator of future well being over the very long run genuine savings gs have been much used in recent years as an indicator of a country s sustainability according to some theorists e g arrow et al 2012 under certain conditions a country with a positive level of gs should experience non declining future utility given the assumption of unlimited substitutability among all forms of capital sometimes called weak sustainability this paper reports the first very long run tests of gs also called comprehensive investment or adjusted net savings as a forward looking indicator of future well being we assemble data for british capital back to 1765 and construct several net investment measures which are used as indicators of two alternative measures of future well being consumption per capita and real wages an allowance for a value of time due to exogenous technological progress is included in some gs measures and we demonstrate the importance of this measure and the choice of discount rate over the very long run on the whole our results do not reject the postulated relationship between gs and future well being and show gs can be a forward looking indicator of future well being for periods of up to 100 years

when is foreign aid policy credible aid dependence and conditionality the author studies foreign aid policy within a principal agent framework he shows that one reason for foreign aid s poor overall record may be a moral hazard problem that shapes the aid recipient s incentive to undertake structural reform the model s basic prediction is a two way relationship disbursements of foreign aid are guided in part by the needs of the poor anticipating this recipients have little incentive to improve the welfare of the poor preliminary econometric work shows that the data support this hypothesis in principle conditionality could partly solve this problem but only if the donor can make a binding commitment to increase disbursements in good relative to bad states without such a commitment technology aid disbursements remain guided by the needs of the poor and recipient countries maintain a low effort to reduce poverty contrary to the conventional wisdom found in the aid literature the author shows that the welfare of all parties might be improved by using tied project aid or by delegating part of the aid budget to an international agency with less aversion to poverty

a three gap model of foreign transfers and the gdp growth rate in developing countries abstract a simplified macroeconomic framework is developed for the fiscal gap which is considered to be an important stumbling block for adjustment with growth in highly indebted developing countries distinctive characteristics of a fiscally constrained economy are compared with those of economies constrained either by the availability of savings or foreign exchange tentative implications for external conditionality accompanying debt relief measures are derived

the multinational firm direct investment is incorporated into a simple general equilibrium model of international trade the analysis focuses on an attempt to endogenize the internalization decision it is argued that a reasonable approach assumes that arm s length contracts must be simple so that complex arrangements require internalization the model relates direct investment to the degree of underlying uncertainty and to fundamental trade determinants such as relative factor endowments the behavior of the model contrasts sharply with that of the markusen helpman model which takes internalization for granted

choosing to target what types of countries get different types of world bank projects well governed countries are more likely to make use of foreign aid for the purposes of economic development and poverty alleviation therefore if aid agencies are providing funds for the sake of development these countries should receive more aid and categorically different types of aid as compared with poorly governed countries in poorly governed countries aid should be given in forms that allow for less discretion using an original data set of all world bank projects from 1996 to 2002 the author distinguishes programmatic projects from investment projects and national from subnational investment projects if the world bank allows more discretion in well governed countries then it will choose to provide programmatic and national aid for these recipients the author presents evidence that the world bank provides a larger proportion of national investment lending in better governed countries with regard to programmatic lending he finds mixed evidence among counties eligible for international development association ida aid good governance surprisingly is associated with a lower proportion of programmatic aid whereas for international bank for reconstruction and development ibrd borrowers good governance is associated with a higher proportion the author subjects these results to a number of robustness checks although he confirms the existing result in the literature that the world bank provides larger overall amounts of aid to better governed countries his examination of the disaggregated data leads to questioning whether both lending wings of the world bank are designing aid programs in the most prodevelopment way possible

wealth as a criterion for sustainable development in this article the authors define sustainable development as an economic programme along which social well being does not decline over time it can be shown that the requirement is equivalent to the maintenance of a comprehensive measure of wealth where an economy s wealth is defined to be the social worth of its entire array of capital assets including natural capital using data published by the world bank on the world s poorest regions countries which would be regarded as having performed well if judged on the basis of such indices as gnp per head or the human development index are found to have grown poorer a few alarmingly so

knowledge market failure and the multinational enterprise a reply debate is an indication that an issue warrants discussion the comments of james love and donald mcfetridge in this issue are fine statements that articulate a received wisdom their comments differ with each other and these differences remind us that there is less consensus in our understanding of internalization and transaction costs than commonly supposed if we do not address all of the commentators specific points it is not for lack of appreciation but because it is our belief that a fuller vision of the terrain already mapped and that which is yet uncharted would provide a more useful basis for exploration and discovery a listing of issues is the task of a referee while a published debate might perform a useful task by laying out the contours of the research tradition and future

the transition from decentralized to network based mnc structures an evolutionary perspective this paper investigates and models the transition process within established multinational corporations mncs in moving from decentralized toward network based structures whereas there has been substantial research on various mnc models there has been little longitudinal research on the movement toward projected network based models this paper develops an evolutionary perspective of this transition distinguishing adjustments altering how the mnc defines its global strategy where it locates key resources and how it structures and manages operations it argues that rather then being a planned process each phase represents a viable strategic response to then existing challenges and opportunities the paper also argues that the focus of the process shifts over time initially focusing on building organizational linkages and adjusting the quantity and nature of resources within dispersed units and later shifting toward reallocating resources and roles across units

strategic considerations in invention and innovation the case of natural resources strategic considerations may induce a resource importing country to invent a substitute earlier than it intends to put it to use there are also circumstances in which it would wish to delay an invention date even if it could obtain it at an earlier date at no extra cost similar paradoxical results obtain if resource cartels behave strategically setting prices high may be a way of deterring invention if those engaged in r d are not resource users and the cartel has access to similar r d technology it will pre empt rivals this may not be the case if resource users can also engage in r d

analyzing foreign market entry strategies extending the internalization approach a new fully integrated analysis of the foreign market entry decision is presented encompassing the choice between exporting licensing joint venturing and wholly owned foreign investment the choice between acquisition and greenfield investment is examined and so too are options based on subcontracting and franchising the model extends the insights of internalization theory and draws on concepts from the economics of industrial organization a special feature of the model is the distinction between investment in production facilities and investment in distribution facilities an important practical distinction that has been overlooked in much of the international business literature the strength of competition from indigenous rivals is emphasized as a determinant of entry strategy into both production and distribution

the role of technological progress in testing adjusted net savings evidence from oecd countries abstract in this paper we investigate the relationship between comprehensive measures of savings and changes in future consumption in oecd countries this relationship is at the basis of the interpretation of adjusted net savings as a weak sustainability indicator and so evidence of its validity provides support to the use of this indicator we construct various measures of comprehensive savings for 20 oecd countries to include depletion from non renewable resources human capital investment and technological progress given their importance especially for rich countries we focus on the role of technical progress and human capital in the form of changes in education level we do not find strong evidence in favor of including green adjustments in the conventional net savings however we find compelling evidence for the inclusion of technological progress since this involves a forward looking term the above result suggests that to construct an indicator of weak sustainability from conventional net savings some estimate of future technological progress is needed

wealth and sustainability for economists in 1974 it was a live question whether the exhaustion of natural resources such as oil would necessarily lead to the decline of economic activity solow showed that constant levels of consumption could be sustained in the face of exhaustibility if there is sufficient substitutability between produced and natural factors of production hartwick then proved that underpinning this result is a saving rule set investment in produced capital equal to the value of resource depletion at each point in time a large literature has shown that a comprehensive measure of the change in real wealth net saving plays a central role in determining whether current well being can be sustained in particular current declines in real wealth signal that future well being will also decline a result that has been confirmed empirically using data for developing countries changes in wealth and sustainability are therefore joined at the hip the current composition of wealth serves to define the policy challenges that countries face in achieving sustainable development if substitution possibilities are limited between natural and other factors of production as one might expect then technical progress is a necessary complement to policies for sustainability

credible signals of the release of new versions i introduction many products are marketed some time after they have been developed for instance a new smartphone may be developed and tested well before it is available for purchase a new car might be prototyped and driven months before it comes to the market indeed a firm will often have several products concurrently in a development pipeline consumers may know a product is in that pipeline without knowing its progress towards the market because the outcome of such development and testing is not visible to outsiders the firm knows whether it can market a product before consumers do consumers are uninformed about when and if the new product will be marketed to them economists have long recognized that the present demand for durable goods depends on future prospects such as the future price or the introduction of an improved version 1 the existence of such an improved version is often the seller s private information if consumers anticipate a new version some will defer purchases until the new version is available and the seller will face low demand for the present version disclosing the new version is not in a monopoly seller s interest a seller whose good does not have a new version would also like to communicate that fact to consumers while a firm with a successful product innovation can credibly disclose the new version with relative ease a firm that has failed to develop a new product could have great difficulty convincing consumers that the product has no new version in such situations it is important to examine whether prices can inform consumers whether a new version will be marketed in the near future in a recent paper choi et al 2010 developed a model with a risky product development process in which reputation effects allow cheap talk announcements to signal successful product development to consumers an announcement induces consumers to delay or divert purchases to the announcer s coming product which increases the announcer s profit and can improve welfare 2 in their model the announcer and her non innovative rivals supply the original good competitively because of this an announcement does not reduce profit on the current version this paper will focus on markets where the seller has substantial market power before innovating so announcing a successful product development has a cost in terms of current revenue further because we attend to prices as signals this model may also apply to markets where a long run relationship between consumers and firms may not be sustainable another objective of this paper is to examine the welfare effects of mandatory disclosure a government policy mandating disclosure of any new version is an alternative means of informing consumers 3 as long as firms are not willing to lie to the government such a policy would credibly communicate whether a new version of a durable is coming mandatory disclosure would bring about full information as consumers are informed about any improved future version before observing the price of the current version in this paper we explore a two period model of a durable good monopoly in which consumers are initially uninformed about whether there will be a new version of the current good the monopoly seller is privately informed if he will be able to market an improved version in the second period in the first period consumers must decide whether to purchase the good now or wait for an upgraded version they may be able to infer from the price of the current version whether the seller will bring a new version to the market it is important to see first whether prices can serve as signals and second how welfare compares between any signaling outcome and a full information benchmark corresponding to mandatory disclosure we will show that there is a unique equilibrium supported by intuitive beliefs in this equilibrium the seller s private information about an improved version is completely revealed to consumers

binding constraint on economic growth under export oriented industrialization and globalization the two gap model of economic growth implies that different constraints on economic growth namely the savings and the foreign exchange availability are binding at different times this article estimates these varying binding constraints in 16 countries in east and southeast asia and latin america and explores their differences across countries regions and periods i show that the east and southeast asian countries which are recognized to be successful in export oriented industrialization are less constrained by the foreign exchange availability with reinforced export capacity than the latin american countries which had carried some inertia of import substituting industrialization policy until the 1980s in addition the economic growth turns out to be more constrained by the domestic savings in recent years which can be a reflection of capital account liberalization policies typically implemented in the late 1980s and 1990s and or a diminishing return to export led growth in either case this mi

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

the optimal timing of a foreign direct investment analyses of the optimal timing of foreign direct investment fdi decisions have been curiously lacking in the general literature on multinational enterprises cf buckley 1979a b although comparative static analyses exist comparing exporting to the host country with market servicing from a production unit sited in the host country horst 1971 hirsh 1976 the only attempt to predict the timing of the switch from exporting to foreign based production is that of aliber 1970 although vernon 1966 gives a cost based rationale for the switch this chapter attempts to fill this gap in the theory of fdi section 2 1 outlines and criticises previous attempts to deal with the problem sections 2 2 4 present a simple model which ignores set up costs and sections 2 5 and 2 6 give a more detailed analysis including such costs further extensions of the theory are considered in section 2 7 and the conclusions are summarised in section 2 8 the problem emerges as being more complex than had previously been appreciated

the impact of journals and authors on international business research a citational analysis of jibs articles in this paper we use citational analysis to examine the influence of individuals and disciplines on international business research we collected citational data over the ten year period 1984 to 1993 from every issue of the journal of international business studies we found that management economics marketing and finance disciplines have had significant influence on international business research and identified researchers such as dunning porter vernon casson rugman and hofstede as having made significant contributions to international business research

assessing sustainability a comprehensive wealth accounting prospect an application to mozambique we estimate the wealth of mozambique in 2000 and 2005 in order to assess the sustainability of its development path our methodology builds on arrow et al 2010 we show that mozambican wealth increases through human and physical capital accumulation while the pressure on natural capital remains low the growth of total factor productivity enhances the outcome of the different capital assets but population growth has a strong downward effect on wealth per capita results suggest that mozambican development was sustainable between 2000 and 2005 but these remain ambiguous and are highly sensitive to data and assumptions used

reappraising the eclectic paradigm in an age of alliance capitalism this article discusses the implications of the advent of alliance capitalism for our theorizing about the determinants of mne activity in particular it argues that due to the increasing porosity of the boundaries of firms countries and markets the eclectic or oli paradigm of international production needs to consider more explicitly the competitive advantages arising from the way firms organize their inter firm transactions the growing interdependencies of many intermediate product markets and the widening of the portfolio of the assets of districts regions and countries to embrace the external economies of interdependent activities

the ghost of financing gap testing the growth model used in the international financial institutions abstract the harrod domar growth model supposedly died long ago still today economists in the international financial institutions ifis apply the harrod domar model to calculate short run investment requirements for a target growth rate they then calculate a financing gap between the required investment and available resources and often fill the financing gap with foreign aid the financing gap model has two simple predictions 1 aid will go into investment one for one and 2 there will be a fixed linear relationship between growth and investment in the short run the data soundly reject these two predictions of the financing gap model

licensing versus direct investment a model of internalization by the multinational enterprise a firm must decide whether to serve a foreign market by exporting building a foreign branch plant or licensing the production to an existing foreign producer the existence of reputations implies that any licensing agreement must provide a licensee with the incentive to maintain the reputation this creates a motive for the firm to internalize transactions by building a branch plant i e by becoming a multinational the model reflects a more general notion that the inability of the firm to control a licensee s agent s actions can provide incentives for multinational activity the paper explores the determinants of the firm s mode of operation as well as the consequences of certain government policies

genuine savings and sustainability genuine savings gs has emerged as the leading economic indicator of sustainable economic development at the country level it derives from the literatures on weak sustainability wealth accounting and national income accounting we discuss the theoretical underpinnings of gs focusing on the relationship between changes in a nation s extended capital stock and the future path of consumption the indicator has entered widespread use propelled by the world bank s publications despite its varying performance as a predictor for future consumption notwithstanding the extensive body of literature reviewed promising future research avenues are identified

a new perspective on planned obsolescence automobile manufacturers have long had a policy of introducing annual style changes into their new model cars textbook publishers have a policy of periodically bringing out revised editions of their popular books recently ibm changed the operating system used in its personal computers causing a reduction in the compatibility between its old and new machines if one were to ask the typical man in the street to explain what is happening in these markets he would not hesitate before giving the following answer in economists terminology he would say that for the above firms the incentive to introduce new products that make old units obsolete is too high i e the firms have an incentive to practice planned obsolescence of course just as is true for the man in the street economists have also long observed and commented on the speed with which new products are introduced for example galbraith 1958 suggests that the annual model changes of automobile manufacturers are socially wasteful while fisher griliches and kaysen 1962 provide empirical estimates of the costs of these changes there have also been numerous theoretical attempts to model the idea of planned obsolescence or the related idea of killing off the market for secondhand goods but most of these models have in fact considered the choice a monopolist faces concerning how much durability to build initially into his product rather than the monopolist s incentive to introduce new versions of his product over time 1 in this paper i consider planned obsolescence from the standpoint of a firm that can change the nature of what it sells and show that the man in the street is in fact correct in many settings the incentive for a durable goods monopolist to introduce new products that make old units obsolete will be above that which is socially optimal

nash equilibrium search for the best alternative in a recent paper weitzman econometrica 47 1979 641 654 described a policy of optimal search for the best alternative the present paper is concerned with the development and characterization of a policy of nash equilibrium search for the best alternative specifically it is shown that under certain monotonicity assumptions and under the assumption that firms have incomplete information regarding the results of rivals search behavior a nash equilibrium search policy exists and has the same form as weitzman s optimal search policy

multinationals multi plant economies and the gains from trade a general equilibrium model of a multinational enterprise based on economies of multi plant operation is developed these economies are modelled as arising from the existence of a joint input whose productivity in each production facility is independent of the number of facilities maintained by a firm the multinational thus offers the world increased technical efficiency by eliminating the duplication of the joint input that would occur with independent national firms since this technical efficiency may come at the expense of increased market power the full determinants of home country host country and world welfare are considered

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

internalization and the mne a note on the spread of ideas this paper examines the reasons for the impact of buckley and casson s the future of the multinational enterprise 1976 on research in international business ib earlier work concentrated on ownership specific advantages or locational determinants rather than the central concept of internalization the few exceptions were incomplete or not well known internalization as applied to the mne spread rapidly because of the appeal to ib researchers of an analytically powerful idea that was based on institutional economics and involved an accessible methodology the spread was also helped by the parallel growth of transaction costs in the domestic theory of the firm and the publication activity of the authors and their associates

comprehensive wealth and future consumption accounting for population growth economic theory predicts that the current change in national wealth broadly defined to include natural and human capital as well as produced capital genuine savings determines whether the present value of future changes in consumption is positive or negative theoretical research has focused on the effects of population growth on this relation but no rigorous empirical investigation has been conducted panel data for 64 developing countries during 1970 82 are used to test the effects of three adjustments for population growth including one that controls for omitted wealth although the adjustments have substantial impacts on estimates of genuine savings they lead to only limited improvements in the relation between those estimates and subsequent consumption changes even without adjustments for population growth adjustments for natural resource depletion improve the relation significantly policymakers and economists can interpret published estimates of genuine savings as signals of future consumption paths if and only if the estimates include adjustments for natural resource depletion but better estimates of capital stocks are needed before it can be confidently said that adjustments for population growth significantly improve the accuracy of those signals

knowledge market failure and the multinational enterprise a comment the purpose of this note is to comment briefly on two papers published in this journal kogut and zander 1993 and love 1995 kogut and zander k z argue that market failure is not necessary to explain the existence of multinationals or indeed any firm love argues that the existence of a firm necessarily reflects a market failure but that opportunism is not necessary for market failure to occur i have problems with the logic of both papers

the effect of national corporate responsibility environment on japanese foreign direct investment we examine the relationship between japanese foreign direct investment fdi and the national corporate responsibility ncr environment in host countries using corporate social responsibility and international business theories based on data from the japanese government s ministry of finance accountability and other sources we find that the level of ncr has a positive relationship with fdi inflow for developing countries the relationship for developed countries is negative but not statistically significant the underlying host country development stage moderates the relationship the results can help deepen understanding of fdi behaviors and have practical implications for host countries in terms of attracting fdi

invention and innovation under alternative market structures the case of natural resources this paper examines the interactions between market structure and resource allocation over time when there is endogenous technical progress the structures considered are a planned economy pure monopoly and competition with patent rights in an efficient allocation the date of invention coincides with the date of innovation the date at which technology is used this is also true with a pure monopoly but monopoly retards technical progress relative to the efficient level competition for patents rights to a new technology results in excessively rapid technical progress if the resource endowment of the economy is sufficiently large also competition may lead to sleeping patents where invention strictly precedes the date of innovation

the dynamic implications of foreign aid and its variability abstract the paper examines the effects of aid and its volatility on consumption investment and the structure of production in the context of an intertemporal two sector general equilibrium model calibrated using data for aid dependent countries in africa a permanent flow of aid mainly finances consumption rather than investment consistent with the historical failure of aid inflows to translate into sustained growth large aid flows are associated with higher real exchange rates and smaller tradable sectors because aid is a substitute for tradable consumption aid volatility results in substantial welfare losses providing a motivation for recent discussions of aid architecture stressing the need for greater predictability of aid these results are also consistent with evidence from cross country regressions of manufactured exports presented later in the paper

durable goods market structure and the incentives to innovate a commonly cited finding in the innovation literature is that a monopoly tends to innovate too little this paper demonstrates that a monopoly may devote more resources to innovation than is socially optimal if it produces a durable good this possibility occurs because durability creates new innovation incentives once an initial stock of a durable good has been produced the monopoly faces a residual demand for the good innovation may allow the monopoly to more profitably exploit this residual demand and this ability may lead the monopoly to devote more resources to innovation than is socially optimal copyright 1987 by the review of economic studies limited

r d and buyers waiting option anticipation of technological progress may induce buyers to delay the adoption of new technologies we analyze how buyers waiting option may feed back into firm s timing of innovations buyers are shown to have inefficiently weak incentives to wait for potentially better products this induces firms to accelerate the introduction of new products furthermore buyers inclination to adopt new technologies prematurely expands firms scope for preemption of potential rivals the analysis sheds light on r d competition in durable goods markets such as the market for aircraft

a theory of economic obsolescence a new generation of durable goods makes an old generation economically even if not physically obsolete economic obsolescence due to technological innovation requires the durable goods monopolist to implement price discrimination in two dimensions both between consumers with different valuations and between consumers with different purchase histories equilibrium in the game between the durable goods monopolist and consumers depends on the extent of economic obsolescence and the relative sizes of the consumer groups underinvestment in innovation may take place this contrasts with the standard literature on planned obsolescence where the durable goods monopolist overinvests in durability reducing technology

genuine savings leading indicator of sustainable development abstract the world bank recently began publishing estimates of countries genuine savings a comprehensive measure of net investment across all forms of capital natural and human as well as produced this article presents the first empirical investigation of the consistency of the bank s estimates with the hypothesis that net investment should equal the difference between a country s average future consumption and its current consumption results show that the bank s estimates are consistent only with weak versions of this hypothesis and then only for developing countries moreover a simple autoregressive integrated moving average arima model outperforms any net investment measure comprehensive or conventional as a predictor of the difference between current and future consumption in sum the bank s net investment estimates tend to move in the same direction as the difference between current and average future consumption in developing countries but they have little value for predicting the mag

preemptive patenting and the persistence of monopoly this article takes a different tack and inquires whether institutions such as the patent system create opportunities for firms with monopoly power to maintain their monopoly power the results apply to other situations such as brand identification spatial location and capacity expansion which share the characteristic that early or preemptive actions may lower the returns to potential competitors

assessment of the theory of comprehensive national accounting with data for portugal we present time series tests of the quality of genuine savings and green net national income for predicting welfare changes these tests check the validity of the theory of comprehensive national accounting and more broadly of the theory of economic growth the value of technological progress is included as well as the effects of business cycles we use estimates for portugal as inputs overall our results indicate that both genuine savings and changes in green net national income have the same sign as changes in welfare but reject the hypothesis that the estimated comprehensive national accounting measures coincide with the theoretical expressions the results also suggest that comprehensive accounting indicators perform better than conventional national accounting indicators implying that in general the corrections proposed by the comprehensive accounting theory add explanatory power to conventional measures the exception is the inclusion of education expenditures and technological progress which decrease explanatory power excluding business cycles from green net national income increases the agreement with the theory comparing both indicators in general genuine savings presents better results

transaction costs risk aversion and the choice of contractual arrangements publisher summary this chapter discusses transaction costs risk aversion and the choice of contractual arrangements every transaction involves a contract and the transactions conducted in the marketplace entail outright or partial transfers of property rights among individual contracting parties the contractual arrangements through which these transfers are negotiated are several and varied the chapter presents a theory that states that economic efficiency is the same under various land tenure arrangements subject to the constraint of private property rights although transaction costs exist in the real world the theory enables the understanding of much of the farming behavior however the presence of a variety of contractual arrangements under the same constraint of competition poses the question of the choice of these arrangements if a firm can increase efficiency in production by employing productive resources of more than one resource owner a contract to combine the resources will be obtained the formation of the contract involves partial transfers of property rights in one form or another such as leasing hiring or mortgaging

aid intensity in africa abstract aid to sub saharan africa ssa is falling rapidly after reaching historically high levels in the early 1990s we provide a critical review of aid data and place the resource intensity of current flows in crosscountry and intertemporal perspective aid to ssa is not unusually high given the structural characteristics of african countries but it rose more rapidly than predicted until the mid 1990s we introduce the concept of transactions intensity and show that by some measures the management costs accompanying each dollar of aid to africa are comparatively high

market structure and innovation a survey economics we all recite deals with allocation of limited resources towards satisfaction of unlimited wants resources are typically identified as land labor and capital plus a technology that determines their transformation into consumer goods disparity between the available goods and services and the desired gives rise to scarcity and the question of what how and for whom to produce the focus then shifts to description and evaluation of alternative resource allocation mechanisms for making the choices the pareto criterion by which an allocation of resources is deemed efficient if any reallocation improving the position of some individual worsens the position of others is a commonly employed gauge of a mechanism s performance in the absence of externalities increasing returns to scale and uncertainty a perfectly competitive market system yields a pareto optimal allocation of resources this underlies the view that individual self interest is compatible with society s interest the further conclusion that pareto optimality may not be achieved via the market system in the presence of monopoly elements provides an economic rationale for antitrust laws the objective of a resource allocation mechanism appears to be according to the analysis described above to make the best of available resources the alternative objective of relaxing constraints through expanding the resource base or developing new technology seems to be beyond its scope thus until rather recently technical advance had been regarded in the mainstream of economic theory as unmotivated by the quest for profits and substantially unaffected by resource allocation instead as j schmookler observed technology had been viewed as a parameter like the weather affecting the outcome of resource allocations but itself unaffected by them 84 1965 evidence that technological progress has significantly contributed to growth in productivity together with a substantial increase in research and development activity largely financed by government and carried out by industry see f machlup 51 1962 may have spurred reconsideration of this view once technical advance is regarded as an economic variable it is natural to in

models of the multinational enterprise flexibility is identified as the hallmark of recent modelling of the multinational enterprise the focus on flexibility is a response to the rationalization and restructuring of international business which has occurred since the end of the golden age of western economic growth flexibility has been south in factor markets intermediate product markets and markets for final products it has been sought by both governments and firms flexible firms are attracted to locations with flexible host governments this article contrasts the modern research agenda based on flexibility with the more traditional research agenda which predominates in the literature reviewed by caves 1996

aid growth and devolution summary this paper examines whether the degree of fiscal decentralization in aid receiving countries matters in explaining aid effectiveness the decentralization theorem predicts that the devolution of powers should increase aid effectiveness since local decision makers are better informed about local needs thereby decentralization may also have reverse effects e g through coordination problems excessive regulation administrative costs and local capture we use panel data for up to 60 countries and find that aid contributes to economic growth in centralized developing economies whereas it is less effective or even harmful in decentralized countries the cases of indonesia the philippines and uganda support our findings our results imply that donor countries should carefully consider how the two development instruments foreign aid and decentralization interact

adjustment with growth abstract this paper describes and examines simple versions of the analytical approaches employed by the international monetary fund and the world bank in designing adjustment programs that support their lending activities in the case of the bank this means essentially a variant of the two gap growth model and for the fund a model derived from the monetary approach to the balance of payments an attempt is also made to merge the fund and bank approaches within a consistent framework to demonstrate their complementarity

practical implications of game theoretic models of r and d the purpose of this paper is to survey recent game theoretic models of research and development and to ask whether they yield practical implications or testable hypotheses the papers i will be discussing have been written or published within the past five years they have a good deal in common relying upon similar assumptions and building upon each other because of this the literature surveyed here may seem narrow and some relevant work has probably been inadvertently omitted i apologize for these omissions for want of space i will not discuss the normative conclusions of this literature

empirical testing of genuine savings as an indicator of weak sustainability a three country analysis of long run trends genuine savings has emerged as a widely used indicator of sustainable development this approach to conceptualising what sustainability is about has strong links to work published by anil markandya and colleagues over 20 years ago in this paper we use long term data stretching back to 1870 to undertake empirical tests of the relationship between genuine savings gs and future well being for three countries britain the usa and germany our tests are based on an underlying theoretical relationship between gs and changes in the present value of future consumption based on both single country and panel results we find evidence supporting the existence of a cointegrating long run equilibrium relationship between gs and future well being and fail to reject the basic theoretical result on the relationship between these two macroeconomic variables this provides some support for the gs measure of weak sustainability

durable good monopolies with rational expectations and replacement sales a monopoly producer of a durable good is examined under the previously uninvoked assumption that the good depreciates and hence that replacement sales must occur if a fixed stock of the good is to be maintained we find two ways in which the no depreciation result that the monopoly will always at least eventually produce a stock equal to that produced by a competitive market may not hold if the length of the trading period is nonzero the limiting stock produced by the firm will be lower than the competitive stock to ensure the profitability of future replacement sales if the firm is able to constrain its production capacity it may choose a constraint that always binds in the sense that it will be impossible for the firm to achieve a stock equal to the competitive stock

corruption and the political economy of resource based development a comparison of asia and sub saharan africa we model how the supply and demand for bribes affects resource use by an economy and the reinvestment of resource rents in other assets this requires adjusting the world bank s measure adjusted net savings for any rent dissipation due to corruption the impacts of corruption on long run changes and periodic growth in the adjusted net savings rate are estimated across african and asian economies from 1970 to 2003 corruption rather than resource dependency per se affects negatively the ability of african countries to reinvest resource rents in the short term but for asian countries corruption is less important than point resources corruption influences long run growth in adjusted net savings rates in all countries and is also the pathway through which this growth is affected by patterns of resource use trade and abundance

the influence of hymer s dissertation on the theory of foreign derect investment the great contribution of stephen hymer s seminal dissertation 1960 was to escape from the intellectual straightjacket of neoclassical type trade and financial theory and move us towards an analysis of the multinational enterprise mne based upon industrial organization theory the magnitude of this breakthrough can be put into perspective by considering the state of the art when hymer wrote twenty five years ago in 1960 the prevailing explanation of international capital movements relied exclusively upon a neoclassical financial theory of portfolio flows in this frictionless world of perfect competition with no transaction costs capital moves in response to changes in interest rate or profit differentials see carl iversen 1936 according to this arbitrage theory capital is assumed to be transacted between independent buyers and sellers that is there is no role for the mne at the time there was no separate theory of foreign direct investment fdi the work did not even ask the question of why is there fdi despite the evidence of sectoral cross investments and the existence of large mnes with intra industry trade if anything the early work on fdi focused upon the where of investment in a particular nation or industry for example dunning 1958 was chiefly interested in explaining u s fdi in britain there was little interest in understanding the reasons for the mne or the nature of its operations the pioneering conceptual insight of hymer was to break out of the arid mold of international trade and investment theory and focus attention upon the mne per se this permits us to treat fdi as a modality by which firms extend their territorial horizons abroad the unique feature of fdi is a mechanism by which the mne maintains control over productive activities outside its national boundaries that is fdi means international production in this view fdi is more than a process by which assets or claims are exchanged internationally see robert aliber 1970 1983 hymer s great insight was in focusing attention upon the mne as the institution for international production rather than international exchange until hymer articulated the process of fdi as an international extension of industrial organization theory it was not possible to understand why the mne transfers intermediate products such as knowledge or technology among its units across different nations while still retaining property rights over such assets today it is widely recognized that the theory of fdi i e international production is primarily about the transfer of nonfinancial and ownershipspecific intangible assets by the mne which needs to appropriate and control the rate of use of its internalized advantage s see rugman 1981 david teece 1981 1982 richard caves 1982 and mark casson 1983 in this paper we first acknowledge hymer s contribution to the theory of fdi and then move on to reinterpret his dissertation in the light of the modern theory of the mne we tdiscussants raymond vernon harvard university robert z aliber university of chicago paul streeten boston university

knowledge market failure and the multinational enterprise a theoretical note this article offers a critique and extension of recent work by bruce kogut and udo zander kogut and zander are correct to argue that opportunism is unnecessary to explain the existence of the multinational but wrong to infer that this indicates an absence of market failure they have identified an important class of transaction costs and market failure which arises in the absence of opportunism but do not cat doubt on the market failure approach to the theory of the multinational their argument that they have identified an important source of ownership advantage is unconvincing and is not supported by the empirical evidence however kogut and zander s work is of considerable significance but in areas different from those that they highlight

reasonable expectations and the first millennium development goal how much can aid achieve summary using a calibrated neoclassical growth model we address three questions i how much growth should aid flows have produced in sub saharan africa over the last three decades ii how much aid would be needed to attain the first millennium development goal mdg 1 of cutting poverty in half by 2015 iii taking proposed aid flows as given how much would structural characteristics such as domestic savings rates and productivity have to change in order to reach the mdg 1 our analysis indicates that past and future expectations for aid in fostering growth and poverty reduction have been too high

the end of the opportunism vs trust debate bounded reliability as a new envelope concept in research on mne governance modern transaction cost economics tce thinking has developed into a key intellectual foundation of international business ib research but the williamsonian version has faced substantial criticism for adopting the behavioral assumption of opportunism in this paper we assess both the opportunism concept and existing alternatives such as trust within the context of ib research especially work on multinational enterprise mne governance case analyses of nine global mnes illustrate an alternative to the opportunism assumption that captures more fully the mechanisms underlying failed commitments inside the mne as a substitute for the often criticized assumption of opportunism we propose the envelope concept of bounded reliability brel an assumption that represents more accurately and more completely the reasons for failed commitments without invalidating the other critical assumption in conventional tce and internalization theory thinking namely the widely accepted envelope concept of bounded rationality brat bounded reliability as an envelope concept includes two main components within the context of global mne management opportunism as intentional deceit and benevolent preference reversal the implications for ib research of adopting the bounded reliability concept are far reaching as this concept may increase the legitimacy of comparative institutional analysis in the social sciences
