local acceptance of renewable energy a case study from southeast germany the european 20 20 20 goals as well as national targets for the next decade require a substantial increase in installed renewable capacity in germany while public support for such measures is high on an abstract level the situation in the local context is often very different here the impact of renewable energy might cause resistance empirical research shows that a community ownership model can have a positive effect on local acceptance our study explores whether such an effect can also be demonstrated in a community co ownership model the question is relevant since larger projects exceed the financial possibilities of most communities leaving them with only co ownership as an option the research design is based on a comparative case study utilizing a questionnaire based survey the results of the survey clearly show that a significant difference in local acceptance exists between the two cases the residents of zschadras where a community co ownership model exists are consistently more positive towards local renewable energy and also towards renewable energy in general the results provide evidence that the co ownership model is a means to reconcile local acceptance with an increased use of renewable energy in germany

motivations for aid to developing countries abstract this paper attempts to identify the underlying principles of aid allocation and particularly the balance of motivations as between the needs of recipient countries and the interests of donor countries two alternative models are fitted by cross country regressions to bilateral and multilateral aid flows to some 80 developing countries in 1969 1970 and 1978 1980 the first recipient need model assumes that all aid is given to compensate for shortfalls in domestic resources this model provides a reasonable explanation for the distribution of multilateral aid but it is clearly not applicable for bilateral aid flows the second donor interest model assumes that all aid serves only donor interests defined to cover political security investment and trade interests this model gives generally good explanations of bilateral aid but is a poor fit for multilateral aid the relative importance of the various donor interests differs sharply among donors the paper ends with an analysis of the shift in the balance of aid over the 1970s towards the recipient need element and with a reference to the sharp change in policy in the 1980s towards increasing emphasis on donor interest aid

coding error or statistical embellishment the political economy of reporting climate aid to benefit from a wide spread public support for climate policy aid agencies strive to show the climate relevance of their development activities using project level aid data and country level political data for 21 dac donors from 1995 to 2007 we test whether this may lead to politically motivated misreporting through keyword search in individual project descriptions and complementary hand coding we assess all aid activities for their actual climate change related content and thereby construct our most relevant control variables econometric results reveal that indeed project coding is influenced systematically by the donor governments ideological orientation as well as by national voters environmental preferences

migration and foreign aid when it comes to linkages between migration and the global allocation of foreign development assistance the size of the immigrant population from a recipient country residing in a donor country is an important determinant of dyadic aid commitments two complementary hypotheses probe this relationship first donors use foreign aid to achieve their broader immigration goals targeting migrant sending areas to increase development and decrease the demand for entry into the donor country second migrants already residing in the donor country mobilize to lobby for additional aid for their homeland empirical tests on a large sample of country pairs made up of twenty two donors and more than 150 recipients over the period 1993 to 2008 show robust support for these hypotheses

nonminimal product differentiation as a bargaining outcome abstract it is well known that in a duopoly model of product choice with quadratic transportation cost the firms locate at the extreme endpoints of the market jehiel 1992 int j ind organ 10 633 641 has examined this model in an infinite horizon setting where in the initial period the firms choose location and in subsequent periods charge the nash bargaining solution prices then in the unique equilibrium both firms locate at the center of the market this paper examines the case when the firms instead charge the prices determined by either the egalitarian bargaining solution or the kalai smorodinski bargaining solution it is shown that central agglomeration is an equilibrium furthermore there is a continuum of symmetric equilibria in addition where the firms locate apart from each other so the products are not necessarily minimally differentiated thus different bargaining solutions provide quite different outcomes

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

are bilateral and multilateral aid for trade complementary using the first comprehensive estimates of ad valorem tariff equivalent bilateral trade costs spanning the time period 2002 10 we examine whether the aid for trade aft inflows reduce bilateral trade costs facing aid recipients if so we ask whether the trade costs reduction effects of aft from bilateral and multilateral sources are complementary by showing the extent to which the observed trade cost reduction effects of aft from bilateral multilateral sources correlate with the magnitudes of aft disbursements from multilateral bilateral sources we present plausible explanation for the cross country variations in the extent to which aft promotes trade flows our findings have thus important policy implications for shaping future discourses on the coordination of disbursements for enhancing the effectiveness of aft

the hard challenge of aid coordination aid coordination is a constant theme of discussion among national and international aid agencies in their search for more effectiveness and efficiency in delivering development assistance this paper seeks to clarify some of the arguments currently made in support of aid coordination and to precise unavoidable trade offs born of the existence of political costs it is anchored in the available literature on aid delivery while focusing on the implementation problems of aid coordination among donor countries in particular it deals with a the issue of consistently and collectively handling possible governance failures in recipient countries and b the impact of heterogeneity of donor countries on the effectiveness of aid coordination

proliferation and fragmentation transactions costs and the value of aid abstract the problem of the proliferation of the number of aid donors and aid channels continues to worsen it is widely and plausibly believed that this significantly reduces the value of aid by increasing direct and indirect transactions costs we contribute to the existing literature by a categorising the apparent adverse effects of proliferation b producing a reliable and fair indicator of the relative degree to which the main bilateral donors proliferate or concentrate their aid c giving some explanation of why some donors proliferate more than others d constructing a reliable measure of the extent to which recipients suffer from the problem of fragmentation in the sources of their aid and e demonstrating that the worst proliferators among the aid donors are especially likely to be suppliers of aid to recipients suffering most from fragmentation there are significant implications for aid policy

explaining the diversity of motivations behind community renewable energy community based renewable energy initiatives may be important actors in the transition toward low carbon energy systems in turn stimulating investments in renewable energy production at the community level requires a better understanding of investors motives this paper aims to study the heterogeneity of motivations that drive individuals to participate in community renewable energy projects and the underlying explanatory factors behind this as well as the implications for their level of engagement in initiatives based on quantitative data from an original survey conducted with two renewable energy cooperatives in flanders the statistical analysis shows that cooperative members should not be considered as one homogeneous group several categories of members with different motives and levels of engagement can be distinguished this heterogeneity is explained by contrasts in terms of institutional settings spatial patterns and attitudes to the diffusion of institutional innovations regarding policy implications the findings suggest that this heterogeneity should be taken into account in designing more effective supporting policies to stimulate investments at the community level the activation of social norms is also shown to be a promising mechanism for triggering investment decisions although the implications of its interplay with economic incentives should be further explored

community renewable energy at a crossroads a think piece on degrowth technology and the democratization of the german energy system abstract degrowth activists and scholars have questioned society s current levels of material throughput and energy use the energy sector is at the core of any modern economy and germany serves as an international showcase for the transition of a large industrialized economy to a low carbon energy system diverse actors organizational models and technologies have contributed to the initiation of germany s energy transition through a wide range of community renewable energy projects the think piece investigates how far these diverse actors embrace the aims of the degrowth movement it also provides a critical account of on the ground realities through six hypotheses and contrasts them with claims made by the degrowth movement it is suggested that community renewable energy projects are at a crossroads while many projects have familiarized thousands of people with alternative economic models there is little evidence of a general change in attitudes towards technology consumption or equity in conclusion a major effort is needed to open initiatives to less affluent actors oppose recent trends of commodification and prevent community renewable energy projects from being engrossed by the dominant political and economic system

aid and debt relief in africa have they been substitutes or complements summary much attention has been paid to helping economies in sub saharan africa ssa to achieve the millennium development goals mdgs the conventional instruments for providing assistance have been foreign aid disbursements and debt relief but have debt relief initiatives complemented or substituted for other aid has debt relief been additional this paper examines the evolving relationship between debt relief and other foreign aid in ssa using recently constructed and improved data estimating a model of aid allocation for 42 ssa countries using panel data for 1988 2006 it finds that the relationships between debt debt relief aid and resource transfers have changed over time this paper interprets how policy changes may have modified the underlying relationship between aid and debt relief

does foreign aid mitigate the adverse effect of expropriation risk on foreign direct investment abstract we construct a model of fdi risk and aid where a country loses access to fdi and aid if the country expropriates fdi we show that i the threat of expropriation leads to under investment ii the optimal level of fdi decreases as the risk of expropriation rises and iii aid mitigates the adverse effect of expropriation risk on fdi the empirical analysis employs data for 35 low income countries and 28 countries in sub saharan africa over the period 1983 2004 we find that risk has a negative effect on fdi and that aid mitigates but cannot eliminate the adverse effect of risk

foreign aid and domestic savings in less developed countries some tests for causality abstract the negative correlation between foreign aid and domestic savings rates in less developed countries is an accepted fact in the existing literature the direction of causality however remains a subject of dispute in this paper we use time series data to investigate causal relationships we conclude that causal relationships are not universal and it is suggested that in those countries where they do hold the direction of causality may depend upon the proportions of aid from bilateral and multilateral sources

let s do it ourselves individual motivations for investing in renewables at community level renewable energy communities have multiplied the last years in many countries even in contexts that the structural conditions are not favorable the paper analyses individual motivations for partaking in local renewable projects and generating energy jointly in an investment community in order to inform policy debates on how to support such communities to do so we applied a socio psychological approach for studying renewable energy communities in germany and the netherlands our results show that mainly gain such as decreasing energy costs and normative such as addressing climate change considerations played a role in the decision but in the background hedonic motivations were also present such as having fun and integrating in a community each of the groups examined emerged in already existing strong communities where trust was relatively high which seems to be an important condition for the realization of local energy projects consequently we argue that tailor made incentives addressing the different types of motivations can be more effective for the support and spread of renewable energy communities

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

can the world cut poverty in half how policy reform and effective aid can meet international development goals abstract poverty in the developing world will decline by about one half by 2015 if the trends of the 1990s persist most of this poverty reduction will occur in asia however while poverty will decline only slightly in africa effective aid could make a contribution to greater poverty reduction in lagging regions even more potent would be significant policy reform in these countries we develop a model of efficient aid in which flows respond to policy improvements that create a better environment for poverty reduction and effective aid we investigate scenarios of policy reform and efficient aid that point the way to how the world can cut poverty in half in every major region

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

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

explaining global patterns of international aid for linked biodiversity conservation and development summary there is little systematic knowledge about the nature extent and trends of international aid for projects that link biodiversity conservation and development goals this study uses a new dataset to analyze spatial and temporal patterns of such aid globally over the past three decades results reveal significant donor selectivity in aid allocation though linked conservation and development aid comprised more than two thirds of all biodiversity related assistance biodiversity aid generally was directed to biodiversity rich well governed countries but countries able to exert greater political leverage secured more linked aid than aid targeted to conservation without a stated development objective

determinants of canadian bilateral aid allocations humanitarian commercial or political in this paper we examine the determinants of the allocation of canadian bilateral aid over the period 1984 2000 we draw on models of donor behaviour that allow us to incorporate humanitarian commercial and political considerations the trinity of mixed motives that affect canadian aid we find that allocations are moderately altruistic recipient country human rights and membership in the commonwealth and la francophonie also affect aid flows most strikingly our results suggest that canadian aid flows became less altruistic over this period and commercial motives became increasingly important jel classification h50 o10 les determinants des allocations de l aide humanitaire canadienne humanitaires commerciaux ou politiques ce memoire etudie les determinants de l allocation de l aide bilaterale canadienne dans la periode 1984 2000 on utilise des modeles de comportement de donateur qui permettent de prendre en considerations les motivations humanitaires commerciales et politiques la trinite de motifs mixtes qui affectent l aide canadienne on decouvre que les allocations sont moderement altruistes le fait pour un pays de defendre bien les droits de la personne et d etre membre du commonwealth et de la francophonie affecte les flux d aide plus important peut etre les resultats suggerent qu au cours de cette periode les flux d aide canadienne deviennent moins altruistes et les motifs commerciaux de plus en plus importants

social impacts of community renewable energy projects findings from a woodfuel case study there is much current interest in the potential of community based renewable energy projects to contribute to transition towards low carbon energy systems as well as displacing fossil fuel consumption by increasing renewable energy generation projects are expected to have a range of social impacts which may result in additional positive sustainability outcomes these include potential to increase acceptance of renewable energy developments awareness of renewable and sustainable energy technologies and issues uptake of low carbon technologies and sustainable pro environmental behaviours to date however there has been little investigation of whether and how these impacts occur this paper presents results from qualitative research investigating the social impacts of a community woodfuel project as experienced by project participants and other local stakeholders findings show projects can raise awareness of renewable energy technologies and increase uptake of renewables overall the case study project successfully changed the local social context for development of woodfuel heating reducing risk for all involved in the future development of this sector particularly in the immediate locality there was some evidence of increased engagement with wider sustainability issues but this was limited to direct participants suggesting local projects need to be supported by wider systemic change to maximise impacts

empirical results of aid motivations australia s bilateral aid program abstract this paper briefly surveys the existing literature on the motivations of overseas aid the emphasis is on the two competing models of recipient need and donor interest and the paper estimates these two models using data for australian bilateral aid both the recipient need model and the donor interest model are supported by the econometric analysis this is in stark contrast to the results of other studies for large states such as the united states and the united kingdom these prior studies show no support for the recipient need model whereas the donor interest model is supported the atypical result for the australian bilateral aid program requires further analysis in terms of non nested hypotheses

collusion agglomeration and heterogeneity of firms abstract jehiel 1992 and friedman and thisse 1993 show that spatial agglomeration appears in a standard two stage location price model if symmetric firms collude in prices we introduce a cost difference between two firms we show that agglomeration never appears in a collusive equilibrium even when the cost difference between firms is sufficiently small

bilateral donors and the age of the national interest what prospects for challenge by development agencies summary foreign aid agencies represent and champion global development priorities within a donor nation increasingly however these agencies sit within donor governments that are strongly committed to upholding the national interest through their development commitments this paper is concerned with how bilateral aid agencies manage this tension and how they might continue to serve the altruistic aims of development the main research question asks if autonomy or a combination of autonomies can improve a development agency s ability to defend the humanitarian imperative of development against normative pressures privileging the national interest by drawing on theories of autonomy within public management literatures it is possible to identify points of leverage for development agencies where spaces for autonomous preferences and actions remain as well as sources of limitation where such opportunities are considerably reduced six types of autonomy are examined across three nations widely perceived as strong performers as donors norway the uk and sweden the paper suggests that while structural autonomy is critical for preserving humanitarian motivations there are also unexplored opportunities within other autonomous spheres a multi dimensional examination of autonomy highlights the varying capacity that development agencies have to resist pressures to strongly nationalize the global development project

responding to policy change new business models for renewable energy cooperatives barriers perceived by cooperatives members abstract renewable energy cooperatives recs in germany have received considerable attention in recent years their number having risen to nearly a thousand since 2004 this growth has resulted largely from germany s feed in tariff system recent changes in this policy however have made the previous rec business models mostly unprofitable so recs are looking for new business models our study aims at identifying those new models and characterizing the implementation barriers recs face to this end we interviewed rec members and management and observed rec annual general meetings we found three significant barriers first risk aversion on the part of both members and management second concerns about the environmental impacts or the ethics of certain models that while legal are not felt to align with the intentions of lawmakers finally the lack of competencies and time of the mostly unsalaried rec management these barriers could put the future of recs at risk and so threaten the contributions recs make to the german energy transition professionalization partnerships and other strategies can help mitigate this risk if recs are to continue to play an important role in the energy transition policy makers would be wise to consider measures to support their continued growth

community energy and social entrepreneurship addressing purpose organisation and embeddedness of renewable energy projects in many european countries renewable energy has evolved through decentralised and small scale forms of organisation these different initiatives are often denominated as community energy in both research and practice by examining community energy initiatives through a social entrepreneurship lens we develop an integrated approach for the analysis of small scale and bottom up energy initiatives our approach relies on three specific analytical dimensions the purpose of the initiative its form of organisation and ownership and its embeddedness into local community or wider social movements we apply this analytical framework to four case studies selected from a larger empirical study on newly emerged forms of organisation in the field of renewable energy across the european union drawing on our findings we characterise social enterprises in the energy sector as collectively owned organisations that combine renewable energy production with more overarching goals of environmental and social transformation and a specific quest for civic participation these initiatives show strong relationships with different social movements and even a potential to transcend the local scale we conclude that given similarities in the two areas of research provide fertile ground for mutual advancement both conceptually and empirically

effects of aid for trade on extensive and intensive margins of greenfield fdi using a panel dataset of 105 developing countries for the period 2003 15 this paper assesses the effects of aid for trade aft on greenfield fdi flows to the aid recipient countries particularly this paper classifies the total dollar value of greenfield fdi flows to each recipient country in terms of four different layers the extensive and intensive margins of projects as well as the extensive and intensive margins of source countries applying the system gmm estimator this paper finds that aft not only increases the dollar value of fdi flows to the recipient countries but also helps diversify the greenfield projects and source countries in addition this paper finds that aft has a greater effect for greenfield fdi from donor developed countries than from non donor developing countries among the three components of aft aid for trade related infrastructure and aid for trade policy regulations are found to have positive links with greenfield fdi irrespective of source country groups yet their effects are larger for developed source countries in contrast aid for building productive capacity hinders greenfield fdi flows from non donor countries while it promotes greenfield fdi from donor countries we offer some explanations for this finding

product differentiation and price collusion the paper analyzes the implications of price collusion with or without monetary transfers on the degree of horizontal product differentiation we find that the principle of minimum differentiation holds i e firms sell the same product when there is no possibility of monetary transfers on the contrary we find that the presence of monetary transfers may induce some product differentiation the reason is that when monetary transfers are possible it is not essential per se to be well located in terms of relative market shares the outcome is then shown to be driven by only two forces 1 choosing a product closer to the competitor s improves the bargaining power 2 choosing a product closer to the one maximizing the joint profit improves the global firm efficiency

partial collusion fosters minimum product differentiation we investigate a spatial duopoly in which the firms simultaneously select locations at the beginning of time once chosen the locations are fixed forever but the firms will choose prices in each of a countably infinite succession of time periods we are interested in equilibrium behavior when the firms will collusively arrange a trigger strategy equilibrium in prices and will select their locations knowing that a particular such trigger strategy price equilibrium will ensue specifically we restrict our attention to prices that support an outcome on the profit possibility frontier at which the ratio of firm 1 s profits to those of firm 2 is positively related to the similar ratio of profits at the single shot noncooperative equilibrium for these profit sharing rules the resulting location equilibrium is unique and involves the pairing of firms at the market center

politics and the effectiveness of foreign aid abstract critics of foreign aid programs have long argued that poverty reflects government failure in this paper i test predictions for aid effectiveness based on an analytical framework that relates aid effectiveness to political regimes i find that aid does not significantly increase investment nor benefit the poor as measured by improvements in human development indicators but it does increase the size of government the impact of aid does not vary according to whether recipient governments are liberal democratic or highly repressive but liberal political regimes and democracies ceteris paribus have on average 30 lower infant mortality than the least free regimes this may be due to greater empowerment of the poor under liberal regimes even though the political elite continues to receive the benefits of aid programs an implication is that short term aid targeted to support new liberal regimes may be a more successful means of reducing poverty than current programs

what are community energy companies trying to accomplish an empirical investigation of investment motives in the german case community energy has become an increasingly important issue in academia and in energy policy circles worldwide citizens jointly investing in and operating renewable energy installations have played an essential role in countries such as germany or denmark building on and extending previous studies we collect survey data on investment motives for a stratified random sample of german community energy companies structural variables are selected using a socio ecological technical systems framework this study aims to identify differences within the community energy sector to better understand investment behaviour and the effects of policy changes despite the small sample coverage at the individual member level the preliminary results of this study suggest that first community energy forms a specific type of social investment and that second there are significant differences between community energy companies especially regarding the assessment of the return motive this motive plays a more prominent role in limited partnerships than in cooperatives and for community wind than for companies focusing on solar or biomass while these and other factors are highly interrelated our data indicate that the social setting and geographical and climatic conditions are the critical ones here these findings may guide further research

the effects of product differentiation on collusive pricing abstract using the spatial competition framework of hotelling 1929 this paper explores the relationship between the degree of product differentiation and the ability of firms to collude with respect to price we show that the minimum discount factor required to support the joint profit maximum as an equilibrium outcome monotonically increases as products become better substitutes when the joint profit maximum cannot be supported the optimal collusive price is shown to decline as products become more substitutable these findings suggest that firms producing stronger substitutes tend to find it tougher to collude in terms of their product price

two stage perfect equilibrium in hotelling s model hotelling i 929 suggests that his spatial competition model can be used to describe a wide range of differentiation problems he points to the selection of product variety within an industry as a potential application most of the subsequent work in his tradition has taken the equivalence of the two problems for granted in this note we look more closely at this equivalence we distinguish between two types of differentiated products according to the variety of preferences assumed with respect to those products building on this distinction we recognize that the demand faced by a firm locating on hotelling s line is analogous to the demand faced by a firm selecting a horizontally differentiated product it should be emphasized thus that the equivalence between the geographical and the product selection problem is by no means general and relies on specific assumptions about consumers preferences next we formulate a small model close to hotelling s one in which firms select a horizontally differentiated product within this model it will be shown that a pure strategy price equilibrium exists for every pair of products this statement is to be contrasted with the results of d aspremont et al i979 who have shown that in the original hotelling s setting an equilibrium fails to exist when firms are too close together 1 in addition we will examine the product selection problem faced by firms in a two stage game in the first stage each firm selects a product in the second stage the firm defines a price for its product we will seek the existence of a perfect equilibrium in this game a perfect equilibrium in this context can be viewed as a nash equilibrium in a game in which firms select a product aware of the non cooperative price equilibrium that will occur for each of their choices it will be shown that contrary to hotelling s principle the two firms will maximise their differentiation i e firms will locate at opposite ends of the market

do corrupt governments receive less foreign aid critics of foreign aid programs argue that these funds often support corrupt governments and inefficient bureaucracies supporters argue that foreign aid can be used to reward good governments this paper documents that there is no evidence that less corrupt governments receive more foreign aid on the contrary according to some measures of corruption more corrupt governments receive more aid also we could not find any evidence that an increase in foreign aid reduces corruption in summary the answer to the question posed in the title is no

the fungibility of u s military and non military assistance and the impacts on expenditures of major aid recipients abstract this paper examines the impact of u s military and non military assistance on the allocation of public and private sector spending for eight major recipients over the 1972 1987 period the model assumes that an aid recipient s effective post assistance budget constraint is a priori unknown and must be estimated two versions of the model are tested in version a the data is converted into real u s dollars using official exchange rates in version b the data is converted using purchasing power parity exchange rates provided by summers and heston 1991 major findings are the same for both versions u s aid is highly fungible with a significant portion channeled to the private sector where it finances current consumption relatively more than investment
