aid dispersion measurement in principle and practice summary excessive dispersion of development assistance has been high on the paris agenda on aid effectiveness however there is no agreement in the existing literature on how aid dispersion should be measured and few studies of the extent of the problem we argue for using the theil index for both recipients and donors this relative inequality measure has a major advantage it allows for a perfect decomposition into variation between and within entities exploiting this property we can rank official donors and recipients not only in terms of the total spread but also assess the contributions of geographic and sectoral dispersion we provide a detailed picture of developments along various dimensions globally as well as for countries income groups and regions over 1998 13 we further distinguish between bilateral and multilateral donors consistent with other studies using more limited samples we find little effect of the paris agenda overall aid is more fragmented in sub saharan africa and in the poorest countries globally as well as for most donor and recipient countries between variation is the main driver of the spread lending support to the geographic concentration policies many donor countries have adopted bilateral aid has been somewhat more dispersed than multilateral aid and in both cases the large number of donors controlling similar shares of total funds is a major driver of the total spread the latter suggests that concentration could also be achieved through a reduction of the number of actors on the donor side of the aid industry a perspective that previous studies using other measures have been unable to capture

the futile quest for a grand explanation of long run government expenditure this paper carries out a critical reappraisal of the two contending theories purporting to explain long run government spending wagner s law and different variants of the ratchet effect we analyze data spanning from the early 19 th century until the present day in sweden and the united kingdom hence in contrast to previous studies we evaluate the validity of wagner s law and the ratchet effect hypothesis over a very long time period starting at the beginning of industrialization cointegration analysis is used to investigate the long run relationships between government expenditure and gdp focusing on sub periods and structural breaks moreover we test the ratchet effect hypothesis by estimating models which allow for asymmetric adjustment according to our main results wagner s law does not hold in the long run although the data are consistent with wagner s law between roughly 1860 and the mid 1970s this can be traced to the formation of the modern public sector including the introduction of public education health care and so forth yet wagner s law did not hold during the initial industrialization phase before 1860 and in recent periods gdp only affects the government spending share when we control for population age structure finally we find some evidence of asymmetric adjustment in the uk particularly in the post wwii period however the ratchet effect is not a general cause of the growth of government spending

an empirical re examination of wagner s law abstract it is argued in this paper that for a more meaningful test of wagner s law allowance must be made in regard to prevalence of peace and stability using six different versions and employing both nominal and real data from ten states of the united states wagner s law is vindicated

ngos in bangladesh activities resources and governance summary this paper reports results from one of the first large nationally representative surveys of non governmental organizations ngos in a developing country the ngo sector in bangladesh is highly organized and relatively homogeneous most ngos utilize a branch and headquarters structure in which branches have limited autonomy from headquarters at the branch level most ngos in the country whether big or small focus on credit services derive more of their income from fees for services than from grants rely on salaried rather than voluntary staff keep detailed financial accounts that are externally audited and hire middle class college educated men as managers the convergence to a modal institutional form probably is the result of the persuasive power of ideas sociological pressures toward acculturation and conformity as well as material incentives

a liquidity based model of security design we consider the problem of the design and sale of a security backed by specified assets given access to higher return investments the issuer has an incentive to raise capital by securitizing part of these assets at the time the security is issued the issuer s or underwriter s private information regarding the payoff of the security may cause illiquidity in the form of a downward sloping demand curve for the security the severity of this illiquidity depends upon the sensitivity of the value of the issued security to the issuer s private information thus the security design problem involves a tradeoff between the retention cost of holding cash flows not included in the security design and the liquidity cost of including the cash flows and making the security design more sensitive to the issuer s private information we characterize the optimal security design in several cases we also demonstrate circumstances under which standard debt is optimal and show that the riskiness of the debt is increasing in the issuer s retention costs for assets

catalyzing aid the imf and donor behavior in aid allocation the international monetary fund imf has often asserted that its programs encourage aid by signaling policy credibility commonly referred to as aid catalysis our study investigates this claim for sector specific aid and for bilateral and multilateral donors using data on 136 recipient countries for the 1986 2009 period we employ a two part quantitative model to match the donor decision making process consisting of a first stage recipient selection equation and a second stage allocation equation on selected recipients we find strong support that imf programs catalyze aid on aggregate but the evidence varies across different types of aid aid catalysis is stronger and more robust in sectors linked to the imf s core competency areas namely debt related relief and general budget support but weaker and less robust for infrastructure production multisector and humanitarian aid and non existent for health and education across donors imf programs are associated with increases in aid by countries with larger voting shares in the imf such as the united states and japan but less so by countries with few votes or for multilateral agencies this finding is consistent with research in international political economy arguing that the imf s powerful stakeholders drive the organization s decisions and policies taken together our findings emphasize the imf s multi dimensional impact on the global development agenda an erstwhile overlooked factor in studies of aid allocation while refuting the purported positive effects of imf programs on aid for social policy

aid policy and growth in post conflict societies countries emerging from civil war attract both aid and policy advice this paper provides the first systematic empirical analysis of aid and policy reform in the post conflict growth process it is based on a comprehensive data set of large civil wars and covers 27 countries that were in their first decade of post conflict economic recovery during the 1990s the authors first investigate whether the absorptive capacity for aid is systematically different in post conflict countries they find that during the first three post conflict years absorptive capacity is no greater than normal but that in the rest of the first decade it is approximately double its normal level so ideally aid should phase in during the decade historically aid has not on average been higher in post conflict societies and it has tended to taper out over the course of the decade the authors then investigate whether the contribution of policy to growth is systematically different in post conflict countries and in particular whether particular components of policy are differentially important for this they use the world bank policy rating database the authors find that growth is more sensitive to policy in post conflict societies comparing the efficacy of different policies they find that social policies are differentially important relative to macroeconomic policies however historically this does not appear to have been how policy reform has been prioritized in post conflict societies

the government expenditure economic growth relation in japan an analysis by using the adl test for threshold cointegration based on annual data from japan for the period 1960 to 2010 we investigate the government expenditure economic growth relation in japan by using the autoregressive distributed lag test for threshold cointegration developed by li and lee 2010 in particular we evaluate the validity of wagner s view and the keynesian view in the case of japan the empirical results presented herein indicate that of these two classical economics perspectives only wagner s view holds for japan the findings also demonstrate that the adjustment process towards its long run equilibrium is asymmetric

financial innovation in a general equilibrium model abstract we develop a model of financial innovation in which intermediaries can issue new financial securities against collateral in the form of standard securities intermediaries have to market their innovations and marketing is costly we show that the equilibrium asset structure may exhibit redundancies as frequently observed on financial markets we give conditions for efficiency of financial innovation and show that with small innovation costs the indeterminacy of equilibrium allocations has small utility consequences journal of economic literature classification numbers d52 g10

general equilibrium with endogenously incomplete financial markets abstract the present paper studies a class of general equilibrium economies with imperfectly competitive financial intermediaries and price taking consumers intermediaries optimally choose the securities they issue and the bid ask spread they charge financial intermediation is costly and hence markets are endogenously incomplete an appropriate equilibrium concept is developed and existence is proved competitive equilibria for this class of economies display full indexation of securities payoffs and monetary neutrality even if intermediaries are restricted to issue nominal securities and financial markets turn out to be incomplete this is in sharp contrast with the indeterminacy and non neutrality results established in the literature for incomplete markets economies with exogenously given nominal securities journal of economic literaturclassification numbers d52 g20

financial market innovation and security design an introduction abstract the article describes in the context of theory and practice this special issue of the journal of economic theory on financial market innovation and security design the main focus is on security design in incomplete financial markets possibly with asymmetrically informed traders we first survey the general equilibrium literature which emphasizes the spanning role of securities we then provide a unified framework encompassing the literature that employs a cara guassian setting to study the impact of financial innovation on risk sharing and information aggregation journal of economic literature classification numbers g10 d52

information revelation and market incompleteness this paper introduces a theory of market incompleteness based on the information transmission role of prices and its adverse impact on the provision of insurance in financial markets we analyse a simple security design model in which the number and payoff of securities are endogenous agents have rational expectations and differ in information endowments and attitudes toward risk when markets are incomplete equilibrium prices are typically partially revealing while full relevation is attained with complete markets the optimality of complete or incomplete markets depends on whether the adverse selection effect the unwillingness of agents to trade risks when they are informationally disadvantaged is stronger or weaker than the hirshleifer effect the impossibility of trading risks that have already been resolved as new securities are issued and prices reveal more information when the hirshleifer effect dominates an incomplete set of securities is preferred by all agents and generates a higher volume of trade hirshleifer 1971 was the first to point out that revelation of information can reduce risksharing opportunities in insurance markets resulting in a welfare loss in this paper we build on hirshleifer s insight to develop a theory of endogenous market incompleteness we show that in an economy with asymmetric information in which agents learn from prices an incomplete financial structure may be optimal the reason is that less information is revealed by prices when markets are incomplete than in an otherwise identical economy with complete markets 1 paradoxically a greater degree of incompleteness may result in better risk sharing since the only risks that can be traded are those whose resolution is not common knowledge at the time of trade for the same reason incompleteness of markets may also foster a higher volume of trade the connection between security design asymmetric information trading volume and welfare in financial markets is a subtle one and it is important to isolate its various facets the efficacy of security markets in aggregating and transmitting private information depends on the characteristics of the financial structure and especially on the number of tradeable assets indeed within the rational expectations paradigm informational differences disappear in equilibrium generically when the price vector has

corrupt governments do not receive more state to state aid governance and the delivery of foreign aid through non state actors abstract a core result of the aid allocation literature is that the quality of governance in recipient countries does not affect the amounts of foreign aid received donor countries may still give aid to poorly governed countries because of a dilemma they face those countries most in need typically also lack proper institutions this paper argues that donors try to resolve this dilemma by delivering aid through non state actors using aid shares as well as absolute amounts of aid allocated through state and non state channels and considering different dimensions of governance we provide evidence that bypassing governments via ngos and multilateral organizations is indeed a response to weak recipient state institutions the effect is stronger in aid sectors where donors can more easily switch between channels and weaker for higher levels of economic self interest among donors

asymmetries in the conditional relation of government expenditure and economic growth previous studies on the relationship between government expenditure and economic growth have invariably aggregated periods of strong and weak gdp growth and reported a single government expenditure response coefficient estimate we argue that traditional test specifications of this relationship suffer from aggregation or omitted variables biases by failing to distinguish between diverse economic growth experiences and their impact on government expenditure we reexamine the evidence concerning wagner s law using a proposed conditional test specification that is capable of a separating periods of strong and weak economic growth b accommodating possible asymmetries in the marginal responses of government expenditure to variations in economic growth and c distinguishing between positive and negative asymmetries in such responses we present evidence showing that a the majority of government expenditure responses tend to occur during periods of an economic slowdown characterized by gdp growth t

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

financial innovation and arbitrage pricing in frictional economies abstract frictional economies are fundamentally different from their frictionless counterparts for example in frictional economies the price function is sublinear and thus there will be incentives to innovate when decomposing existing securities and opening new markets innovators serve important economic functions such as allowing investors to obtain consumption at lower costs enabling investors to achieve better risk sharing and making the fundamental value of more payoffs observable in particular innovators serve these functions even when they introduce redundant securities that are not yet issued furthermore in frictional economies the replication based arbitrage valuation approach tends to overprice certain securities while underpricing others journal of economic literature classification numbers c61 g10 g12 g20

inflation indexed bonds and nominal bonds financial innovation and precautionary motives this paper introduces a two period monetary general equilibrium model with proportional transaction costs on nominal and inflation indexed bonds this paper demonstrates that financial innovation on indexed bonds causes equilibrium interest rates of the nominal bond to increase when agents have precautionary saving motives this result implies that ignoring precautionary motives would underestimate savers welfare gain and overestimate borrowers welfare gain from innovation on indexed bonds

wagner s hypothesis in time series and cross section perspectives evidence from real data for 115 countries internationally comparable data on income and government expenditure for 115 countries covering the period 1950 80 are used to assess the validity of wagner s hypothesis individual country time series data and several intercountry cross sections are studied besides a tremendous diversity in the position for various countries the results indicate that while there is support for the hypothesis in some time series data sets such support is lacking in most cross section estimates much of the support for the hypothesis reported in many earlier studies therefore was probably due to either use of limited samples or inadequate data comparability across the observations studied copyright 1987 by mit press

aid allocation by german ngos does the degree of official financing matter using a new data set for 41 german non governmental organisations ngos we analyse the allocation of ngo aid across recipient countries in a tobit regression framework by identifying for each ngo the degree of official financing we address the largely unresolved issue of whether financial dependence on the government impairs the targeting of ngo aid it turns out that german ngos are more active in poorer countries while they do not complement official aid by working under difficult local conditions beyond a certain threshold rising financial dependence weakens their poverty orientation and provides an incentive to engage in easier environments in addition we find that the ngos follow the state as well as ngo peers when allocating aid this herding behaviour is however hardly affected by the degree of official financing

optimal foreign aid and tariffs this paper investigates the optimal choice of foreign aid when trade policies are decided in a non cooperative fashion three alternative scenarios depending on the timing of the actions and on whether aid is tied are analyzed it is shown that in the case where aid is decided before tariffs untied aid can lead to the reduction of the recipient s optimal trade tax when the donor can tie the aid to a reduction in the recipient s tariff the optimal aid level is always positive and the world can always achieve a pareto efficient equilibrium

the impact of expenditure rules on budgetary discipline over the cycle we study the impact of expenditure rules on the propensity for governments to deviate from their expenditure plans in response to surprising cyclical developments theoretical considerations suggest that due to political fragmentation in the budgetary process expenditure policy might be prone to a procyclical bias however this tendency may be mitigated by strictly enforced expenditure rules these hypotheses are tested against data from a panel of eu member states our key findings are that 1 deviations between actual and planned government expenditure tend to be positively related to output gap surprises and 2 expenditure rules reduce this procyclical bias these results are particularly pronounced when the analysis is confined to spending items with a high degree of budgetary flexibility

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

aid allocation through various official and private channels need merit and self interest as motives of german donors summary the previous literature largely ignores the heterogeneity of aid channels used by each single donor country we estimate tobit models to assess the relative importance of recipient need merit and self interest of donors for various channels of official and private german aid across a large sample of recipient countries in 2005 07 our findings underscore the need for a disaggregated analysis of aid allocation aid channels differ significantly in the extent to which need and merit are taken into account yet the german case does not reveal unambiguously superior aid channels

targeting aid to the needy and deserving nothing but promises by reallocating aid to where it is needed most and where a productive use is most likely donors could help alleviate poverty in developing countries the rhetoric of donors suggests that this insight has increasingly shaped the allocation of aid we assess the poverty and policy orientation of bilateral and multilateral aid in different ways in addition to presenting stylised facts based on bivariate correlations we apply a tobit model that captures both altruistic and selfish donor motives we find little evidence supporting the view that the targeting of aid has improved significantly most donors provide higher aid to relatively poor countries but so far the fight against poverty has not resulted in a stronger focus on needy recipients with favourable local conditions the estimation results reveal that the policy orientation of aid critically depends on how local conditions are measured in general however donors appear to be less policy oriented than poverty oriented the response of donors to changing institutional and policy conditions in recipient countries turns out to be fairly weak we reject the proposition that multilateral aid is clearly superior to bilateral aid in terms of rewarding poor countries with better policies and institutions

aid delivery through non governmental organisations does the aid channel matter for the targeting of swedish aid this paper analyses whether aid channelled through non governmental organisations ngos is less affected by selfish donor motivations and better targeted to needy recipient countries than aid distributed by state agencies we employ tobit and probit models and make use of an exceptionally detailed database that allows an assessment of the allocation of swedish aid channelled through ngos in comparison to the allocation of swedish official aid our analysis provides mixed results on the one hand ngos appear to be altruistic as far as available indicators on political and commercial motivations of aid can tell on the other hand needs based targeting of aid by ngos turns out to be surprisingly weak gdp per capita of recipient countries shapes the allocation of official aid but not that of aid channelled through ngos the headcount of absolute poverty has a significantly positive effect on aid allocation but its impact is not particularly strong when ngos are involved overall the swedish case supports the sceptical view that ngos are not necessarily superior donors compared to state aid agencies

keeping a low profile what determines the allocation of aid by non governmental organizations ngos play an important role in international development cooperation but the allocation of ngo aid has rarely been mapped let alone explained based on a representative dataset for 61 important ngos from various oecd countries we analyze the targeting of ngo aid across a large number of recipient countries by jointly considering major determinants of ngo aid in a multivariate regression framework while our results show that ngos are more active in the neediest countries we reject the hypothesis that ngos complement official aid through engaging in so called difficult institutional environments rather they tend to replicate the location choices of official backdonors moreover ngos follow other ngos so that aid gets clustered finally ngos select recipient countries with common traits related to religion or colonial history taken together our findings suggest that ngos keep a low profile rather than distinguishing themselves from other donors and trying to excel under risky conditions

a paradox of redistribution in international aid the determinants of poverty oriented development assistance summary donors differ in the amount of official development assistance dedicated to poverty reduction we investigate the causes of variation over time and donors by employing both a regression approach with aggregate data on bilateral aid and two short country studies on germany and the united kingdom we find that there is a trade off between the total amount of money given and the amount of money given to poor countries the trade off is similar to the paradox of redistribution of targeting vs redistribution in rich welfare states case study evidence illustrates how countries have managed this tradeoff

cointegration and wagner s hypothesis time series evidence for canada it is argued that wagner s hypothesis is essentially a proposition about the secular comovement of income growth and public spending using the engle and granger cointegration tests and time series data from canada the long run validity of wagner s hypothesis is maintained

a time domain transfer function model of wagner s law the case of the united kingdom economy the dynamic relationship which is implied by wagner s law is well established in the literature however the methodology which has been applied to investigate this dynamic relationship has tended to avoid a dynamic specification this paper investigates wagner s law employing transfer function methodology in the time domain for the uk over the period 1946 85

arbitrage short sales and financial innovation the authors describe a model of general equilibrium with incomplete markets in which firms can innovate by issuing arbitrary costly securities when short sales are prohibited firms behave competitively and equilibrium is efficient when short sales are allowed these classical properties may fail if unlimited short sales are allowed imperfect competition may persist even when the number of potential innovators is large if limited short sales are allowed perfect competition may obtain in the limit but equilibrium can be inefficient because of the presence of an externality the private benefits of innovation for firms differ from the social benefits copyright 1991 by the econometric society

competition in financial innovation this paper examines the incentives to innovate securities provided by frictionless competitive markets with short sales to entrepreneurs in economies with symmetric investor utilities we provide the conditions under which a rm s market value is maximized by a complete nancial structure that is when the mechanism that gives rise to market incompleteness is the one illustrated in the classical example of allen and gale 1991 the foundation for incompleteness in that case is derived from innovation costs and free riding among entrepreneurs for the class of preferences where an incomplete nancial structure maximizes the rms market values markets are incomplete with a probability of one even when innovation is cost free in this sense we provide an alternative to allen and gale s foundation for market incompleteness

too close for comfort the impact of official aid on nongovernmental organizations abstract in promoting a new policy agenda bilateral and multilateral donor agencies are keen to finance nongovernmental organisations ngos and grassroots organizations gros on the grounds of their economic efficiency and contribution to good governance this paper reviews the impact of this trend on ngo gro programming performance legitimacy and accountability if finds that much of the case for emphasizing the role of ngos gros rests on ideological grounds rather than empirical verification in addition though the evidence is inconclusive there are signs that greater dependence on official funding may compromise ngo gro performance in key areas distort accountability and weaken legitimacy

more dollars than sense refining our knowledge of development finance using aiddata summary in this introductory essay to the special issue we introduce a new dataset of foreign assistance aiddata that covers more bilateral and multilateral donors and more types of aid than existing datasets while also improving project level information about the purposes and activities funded by aid we utilize that data to provide a brief overview of important trends in foreign aid contributors to this special issue draw on aiddata as well as other sources to analyze aid transparency new donors not previously described or analyzed aid allocation and aid effectiveness our recurring theme in this introductory essay is that aiddata and these initial academic projects refine rather than revolutionize our understanding of aid the database has added significant numbers of new projects dollar amounts donors and details about those projects though there is much more yet to add we worry that aid debates have been driven by too little information and that many claims are based on limited or very poor evidence rectifying these problems will not be instantaneous refining knowledge takes a lot of time and hard work the common feature of the papers in this special issue is their careful attention to nuance and detail in spite of what some recent authors have claimed aid is neither a simple solution nor a sufficient cause of most problems in developing countries its motivations distribution and effects are complex and shifting capturing this complexity requires detailed data careful thought and sophisticated methods that allow scholars to make conditional causal and descriptive inferences 2011 elsevier ltd all rights reserved

government expenditure and economic growth evidence from g7 countries this paper examines wagner s law of public expenditure which emphasizes economic growth as the fundamental determinant of public sector growth using time series data drawn from the g7 industrialized countries over the sample period 1960 1993 it presents evidence on both the short and long run effects of growth in national income on government expenditure by resorting to recent developments in the theory of cointegrated processes an attempt is also made in this study to examine if wagner s law holds between certain key components of government expenditure and income
