non nested models of australia s overseas aid program after briefly surveying the existing on overseas aid motivations some empirical results are presented for australian bilateral aid in terms of the two competing theories in the aid literature namely the recipient need model and the donor interest model the empirical results for austrlia are atypical in that there is support for both hypotheses this is contrast to the results of previous studies of large nation states the united states britain germany france and japan which have found support for the donor interst model but not the recipient need model given that the empirical results reported here are consistent with both models this paper then proceeds to apply the relatively new tests of non nested hypotheses to the models the results indicate that australia s aid program has both recipient need and donor interest concerns i some years the recipient need motive dominates and in other years donor interest dominates

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

the time varying nairu and its implications for economic policy the nairu the unemployment rate consistent with a constant rate of inflation is estimated in this paper as a parameter allowed to vary over time value is determined in an econometric model where the inflation rate depends on its past values demand and supply shocks the nairu estimated for the gdp deflator varies over the past forty years within 5 4 to 6 5 percent its estimated value for the most recent quarter 1996 q2 is 5 6 percent the nairu has declined in recent years in response to global competition immigration other factors weakening labor s bargaining position and the rapidly declining prices of computers and other electronics

reverse moral hazard of liability insurers evidence from medical malpractice claims this study investigates putative differences in the legal defense of medical malpractice claims between liability carriers with distinct ownership forms doctor controlled and commercial stock the scope of a carrier s legal defense is determined by claim characteristics such as injury severity and liability and possibly the doctor s private costs from settling or losing a claim when a carrier does not internalize the doctor s private costs from losing or settling a claim then a conflict of interest arises as the carrier provides a lower level of legal defense than preferred by the doctor i e reverse moral hazard the perception is that doctor sponsored carriers mitigate such conflicts of interest if this is the case we should expect to see differences in the amount spent by the carrier in defense of the doctor and the propensity to settle claims to test these expectations we use medical malpractice claims filed in florida between 1985 and 1990 we indeed find differences in legal defense in t

intergenerational transfers and the social discount rate this paper investigates the relationship between intergenerational asset transfers and the choice of the discount rate for use in cost benefit analysis in a model of a competitive overlapping generations economy constrained by a socially managed exhaustible resource provided that there are no distortions in capital markets and that all agents hold perfect foresight cost benefit techniques will result in a pareto efficient resource allocation if the discount rate is set equal to the market rate of interest but since the path of the interest rate depends on the level of intergenerational transfers cost benefit techniques do not ensure a socially desirable distribution of welfare between generations a social optimum will result only if intergenerational transfers are properly chosen and enforced decentralized private altruism may result in intergenerational transfers that both present and future individuals would agree are too small if members of the present generation attach positive weight to the general welfare of future generations not simply their personal descendants in a world where intergenerational transfers are non optimal second best policy making may imply a constrained optimum that is inefficient together these findings suggest that cost benefit analysis is at best a partial criterion to policy formulation that should be used only in conjunction with ethical principles that define the proper distribution of welfare between present and future generations

an assessment of the stability and growth pact reform in a small scale macro framework abstract this paper contributes to the debate on emu fiscal governance we simulate a small scale macroeconomic model with forward looking agents augmented with a public finance block we account for positive output stabilization and negative via risk premia effects of debt and deficit we compare the working of the fiscal compact with the maastricht 3 deficit limit status quo and a public investment rule we evaluate their performance in terms of output and inflation during fiscal consolidation and following demand and supply shocks at the steady state all rules guarantee long run sustainability the investment rule robustly displays the lowest output loss followed by the status quo the fiscal compact rule appears to be the most recessionary and deflationary

reform of foreign aid policies the issue of inter country allocation in africa abstract the aim of this paper is to assess the inter country allocation of foreign aid by selected donors to 18 recipients in eastern and southern africa esa the five country cases discussed in this paper show that the aid environment has not been supportive of recipients reform efforts during the 1980s a comparison is made between international development agency ida allocation and other donors cross section and time series regressions demonstrate a variety of considerations influencing bilateral aid lastly in discussing present aid policies and coordination efforts three options are analyzed with respect to future aid policies it is suggested that new initiatives by ida in its allocation criteria and aid coordination efforts can yield some progress

inflation persistence and optimal monetary policy in the euro area in this paper we present an optimizing agent model for the euro area to emphasize how the existence of heterogeneity in inflation persistence across regions matters for the design of monetary policy we find supporting evidence of the existence of such a heterogeneity in inflation dynamics across euro area countries in particular based on the estimation of new keynesian phillips curves for five major countries of the euro area we find that inflation in germany has a dominant forward looking component while in the other group of countries inflation show a significant inertial backward looking behavior under this circumstance we study the welfare implications of four monetary policy rules following terms of trade shocks fully optimal optimal inflation targeting hicp targeting and output gap stabilization

the political economy of foreign aid a model of the market for a public good what determines the type and quantity of overseas aid given by individual donor countries answers to this question in the existing literature are polarized into two groups one of them offers a theoretical treatment based on the theory of public goods which is not consistent with the available data and the other offers empirical correlations without any explanatory theory the first group for example pincus and olson and zeckhauser treats aid like defense as an international public good small countries on this approach are free riders spending relatively little themselves while deriving benefits from the expenditures of larger countries but this approach is not consistent with even a casual scrutiny of the oecd aid community in which broadly speaking the smallest countries are the most generous donors 2 the second group for example hoadley and beenstockdiscover correlations between a country s ratio of aid to gnp and certain independent variables which may be expected to influence it e g that country s gnp its dependence on foreign trade its government s position in the ideological spectrum and the state of the domestic economy 3 however these findings are not fitted into any theoretical framework so that it is difficult to work out what they really mean 4 the approach of this paper is to treat foreign aid as a public good for which there is a market albeit a highly imperfect one because the consumers donor country taxpayers are ignorant about the very nature let alone the price of the commodity they are buying on this view factors on the demand side i e taxpayers response to their country s aid program will help to determine the quantity of aid disbursed as well as factors on the supply side such as the donor government s desire to obtain strategic or trading benefits from aid this view

adaptive learning persistence and optimal monetary policy we show that when private sector expectations are determined in line with adaptive learning optimal policy responds persistently to cost push shocks the optimal response is stronger and more persistent the higher is the initial level of perceived inflation persistence by the private sector such a sophisticated policy reduces inflation persistence and inflation volatility at little cost in terms of output gap volatility persistent responses to cost push shocks and stability of inflation expectations resemble optimal policy under commitment and rational expectations nevertheless it is clear that the mechanism at play is very different in the case of commitment it relies on expectations of future policy actions affecting inflation expectations in the case of sophisticated central banking it relies on the reduction in the estimated inflation persistence parameter based on inflation data generated by shocks and policy responses jel e52

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

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

imperfect credibility and inflation persistence in this paper we formulate a dynamic general equilibrium model with staggered nominal contracts in which households and rms use optimal ltering to disentangle persistent and transitory shifts in the monetary policy rule the calibrated model accounts quite well for the dynamics of output and insation during the volcker disinsation and implies a sacri ce ratio very close to the estimated value our approach indicates that insation persistence and substantial costs of disinsation can be generated in an optimizing agent framework without relaxing the assumption of rational expectations or relying on arbitrary modi cations to the aggregate supply relation jel classi cation e31 e32 e52

donor preferences and recipient fiscal behavior a simultaneous analysis of foreign aid we theoretically develop and empirically estimate a preference model determining foreign aid donor behavior aid access and levels are separately determined by endogenous budgetary allocations the international economic environment the distribution of income between countries basic human needs the small country effect and regional bias we find fungibility of aid in recipient budgets is due to donor and recipient preferences despite the importance of other economic influences we find a significant pro poor country bias in aid allocations although little aggregate influence of basic human needs or regional bias the small country effect is significant for two of six donors jel f35 o19 h 77

european inflation dynamics abstract we provide evidence on the fit of the new phillips curve npc for the euro area over the period 1970 1998 and use it as a tool to compare the characteristics of european inflation dynamics with those observed in the u s we also analyze the factors underlying inflation inertia by examining the cyclical behavior of marginal costs as well as that of its two main components namely labor productivity and real wages some of the findings can be summarized as follows a the npc fits euro area data very well possibly better than u s data b the degree of price stickiness implied by the estimates is substantial but in line with survey evidence and u s estimates c inflation dynamics in the euro area appear to have a stronger forward looking component i e less inertia than in the u s d labor market frictions as manifested in the behavior of the wage markup appear to have played a key role in shaping the behavior of marginal costs and consequently inflation in europe

a two part sample selection model of british bilateral foreign aid allocation the allocation of british bilateral foreign aid among developing countries is simultaneously modelled focusing on allocations during the period 1980 87 two aid allocation decisions are analysed using a variant of the lee maddala econometric model the first decision concerns the determination of developing country eligibility for aid while the second concerns the amount of aid eligible countries are allocated given the implied two part decision making process sample selection techniques are employed it is hypothesized that british bilateral aid eligibility and amount decisions are based on bristain s humanitarian commercial and political interests in developing countries results obtained indicate that these decisions are generally consistent with each of these interests especially those relating to the political importance of commonwealth members

comparing alternative phillips curve specifications european results with survey based expectations this article examines inflation dynamics in europe econometric specification tests with pooled european data are used to compare the empirical performance of the new classical new keynesian and hybrid specifications of the phillips curve instead of imposing any specific form of expectations formation direct measures i e consensus economics survey data are used to proxy economic agents inflation expectations according to the results the new classical phillips curve has satisfactory statistical properties moreover the purely forward looking new keynesian phillips curve is clearly outperformed by the new classical and hybrid phillips curves we interpret our results as indicating that the european inflation process is not purely forward looking and inflation cannot instantaneously adjust to changes in expectations consequently even allowing for possible nonrationality in expectations results in a lagged inflation term entering the new keynesian phillips curve for inflation dynamics in europe

uncertain potential output implications for monetary policy abstract a small forward looking model of the euro area economy is used to investigate the implications of incomplete information about potential output for the conduct of monetary policy three results emerge first under optimal monetary policy output gap uncertainty leads to persistent deviations between the actual and the perceived output gap in response to supply and cost push shocks second in first difference form a simple policy rule such as the taylor rule continues to perform relatively well as long as the output gap is optimally estimated third incomplete information implies that it is optimal to appoint a more hawkish central bank

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting
