aid and the public sector in pakistan evidence with endogenous aid summary aid has been the principal source of development finance for the majority of developing countries over the past few decades this has spawned a large literature on the effectiveness of aid which remains essentially inconclusive the empirical literature has tended to evaluate the impact of aid by including it as a variable in a regression for the determinants of some economic performance indicator this paper follows a different strand of the literature and examines the impact of aid on public sector fiscal behavior aid is in general given to the public sector thus any effect of aid is mediated by that sector we specifically address this behavioral feature by analyzing how aid revenue affects government fiscal behavior with respect to tax borrowing and expenditure decisions unlike previous contributions aid is endogenous in our model which has a number of important implications we estimate an econometric model that differs from previous studies not only in this respect but also by allowing domestic borrowing in addition to aid and tax revenue to finance both capital and recurrent expenditure structural and reduced form equations are derived and estimated using 1956 95 time series data for pakistan results indicate contrary to much of the literature that only half of aid has gone to government consumption that it has had a slightly positive impact on public investment and negative impact on tax effort

foreign aid and fiscal governance in melanesia summary recent research suggests that foreign aid is effective at spurring economic growth in recipient countries but its effectiveness is likely to depend upon a number of factors arguably the most important factor determining aid effectiveness is how recipient governments mediate foreign aid inflows this paper investigates this issue for the melanesian countries of fiji papua new guinea the solomon islands and vanuatu for the period 1989 2002 results suggest that foreign aid has led to increases in developmental expenditures and to falls in tax revenues and borrowing results also suggest a very different response to aid grants versus loans

foreign aid taxes and public investment abstract using time series data for india we test the foreign aid public investment hypothesis behavioral equations derived from a maximizing framework are estimated after correcting for econometric and data inadequacies of earlier models the results confirm earlier findings regarding the negative relationship between taxes and government investment in the presence of aid however in contrast to the earlier work we find that grants and loans generally go into development projects with no leakages into consumption moreover bilateral aid actually pulls resources out of consumption and puts them into development projects

anticipated development assistance temporary relief aid and consumption behaviour of low income countries much debate about the effectiveness of foreign aid to developing countries focuses on the assumption that aid flows mainly enhance current consumption rather than being channelled into investment this paper seeks to establish what proportion of foreign assistance is used to finance current consumption the principal hypothesis to be tested is that aid transfers include very heterogeneous components with different marginal propensity to raise consumption estimating the average marginal propensity to consume of all the components of aid as is commonly done may lead to erroneous results the flow of foreign aid from high to low income countries can be classified into two types the first includes income transfers of a relief nature such as emergency and distress relief including drought related food transfers medical and refugee relief and balance of payments crisis support these transfers are generally a temporary response to unanticipated events or shocks to the economy they can be perceived as an attempt by the donor community to help finance what is denoted in the permanent income theory as transitory consumption friedman i957 in addition they can be viewed as an attempt to maintain a subsistence level of consumption by absorbing the shocks to income entirely by changes in savings the low level of savings however and the constraints on foreign borrowing lead to dependency on foreign transfers and prevent domestic savings from being the residual that is almost all of

the impact of foreign aid on the fiscal behavior of asian ldc governments a comment on khan and hoshino 1992 abstract khan and hoshino 1992 analyze public sector fiscal behavior in the presence of foreign aid using data for five south and southeast asian countries this paper first questions a critical hypothesis test on which khan and hoshino s conclusions depend it then extends khan and hoshino s analysis making explicit both the direct and indirect effects of aid contained within their fiscal response model it argues that a number of khan and hoshino s conclusions do not hold in the context of this representation

foreign aid taxes and public investment a further comment abstract the paper in this journal by gang and khan 1991 employed heller s 1975 fiscal response model to demonstrate that aid to india has all been used to finance government investment this conclusion is shown to be a misinterpretation of the model s results which actually suggest that aid has had no impact on government investment at all however the reported parameters are determined by the estimation procedure adopted by gang and khan and not by the indian government s fiscal behaviour

pricing and welfare in health plan choice premiums in health insurance markets frequently do not reflect individual differences in costs either because consumers have private information or because prices are not risk rated this creates inefficiencies when consumers self select into plans we develop a simple econometric model to study this problem and estimate it using data on small employers we find a welfare loss of 2 11 percent of coverage costs compared to what is feasible with risk rating only about one quarter of this is due to inefficiently chosen uniform contribution levels we also investigate the reclassification risk created by risk rating individual incremental premiums finding only a modest welfare cost

impact of foreign aid on the fiscal behavior of ldc governments abstract the purpose of this paper is to examine the impact of foreign aid on the behavior of the recipient governments specifically we look at a sample of less developed countries in south and southeast asia and study their response to foreign aid received their response is measured in terms of their public investment and consumption as well as taxation our paper attempts to make two new contributions to the literature first we try to estimate the impact of foreign aid on a sample of five south and southeast asian countries secondly we improve on the earlier method of a combination of single equation and two step least squares by estimating the whole system with a nonlinear three step least squares method the results confirm the hypothesis that aid does affect consumption investment and taxation of these governments but they also show that the relationship is a complex one in particular grants and loans have different effects on investment and taxation

capital grants and regional public investment in spain fungibility of aid or crowding in effect the aim of capital grants to subcentral governments is to increase their investment however recipients may try to allocate additional resources to cut saving or deficit generating a crowding out effect on self financed investment using data from the spanish autonomous communities during the period 1984 to 1999 the effect of capital transfers on regional public investment saving and deficit are estimated econometric results demonstrate that capital grants have no relevance when explaining the dynamics of saving however in deficit regressions they are shown to be both significant and negative both results lead us to a partial long run crowding out effect of grants on self financed investment

multiple dimensions of private information evidence from the long term care insurance market we demonstrate the existence of multiple dimensions of private information in the long term care insurance market two types of people purchase insurance individuals with private information that they are high risk and individuals with private information that they have strong taste for insurance ex post the former are higher risk than insurance companies expect while the latter are lower risk in aggregate those with more insurance are not higher risk our results demonstrate that insurance markets may suffer from asymmetric information even absent a positive correlation between insurance coverage and risk occurrence the results also suggest a general test for asymmetric information

a structural model of multiple welfare program participation and labor supply work on estimating the labor supply effects of high marginal tax rates in welfare programs has been hindered by the difficulty of estimating the effects of participation in multiple welfare programs simultaneously the authors solve this problem by applying methods of simulation estimation to a model of labor supply and multiple program participation the results show asymmetric wage and tax rate effects with fairly large wage elasticities of labor supply but very inelastic responses to moderate changes in cumulative marginal tax rates implying that high welfare tax rates do not necessarily induce major reductions in work effort copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the industrial organization of health care markets the u s health care sector is large and growing health care spending in 2011 amounted to 2 7 trillion and 18 percent of gdp approximately half of health care output is allocated via markets in this paper we analyze the industrial organization literature on health care markets focusing on the impact of competition on price quality and treatment decisions for health care providers and health insurers we conclude with a discussion of research opportunities for industrial organization economists including opportunities created by the u s patient protection and affordable care act

health insurance and the demand for medical care evidence from a randomized experiment we estimate how cost sharing the portion of the bill the patient pays affects the demand for medical services the data come from a randomized experiment a catastrophic insurance plan reduces expenditures 31 percent relative to zero out of pocket price the price elasticity is approximately 0 2 we reject the hypothesis that less favorable coverage of outpatient services increases total expenditure for example by deterring preventive care or inducing hospitalization

aid the public sector and the market in less developed countries a reply the article in this journal by mosley et al i987 concludes its analysis of aid effectiveness as demonstrating inability of development aid over more than twenty years to provide a net increment to overall growth in the third world p 636 this note purports to show that this conclusion which is ostensibly distressing as the authors claim is not warranted the section of the study which is the basis of the conclusion cited and the subject of this note is a cross section regression analysis full details of which are shown in mosley et al table 3 the note is concerned with the relation between the dependent variable specified as the growth rate of real gdp per cent per annum hereafter gdp and aid specified as a percentage of gdp hereafter aid the aid results with only two significant positive coefficients in one subsample certainly give no basis for claiming aid effectiveness in terms of gdp growth the intention in this note is to interpret the results which are assumed to be valid this is made possible by the fact that the authors have helpfully provided the full input set of mean values derived from the raw data from this it is possible to calculate the gdp aid relationship for each country for the second and third period the procedure for deriving these relationships is as follows for each country the mean values of the time series of gdp and aid are extracted from the data for i 960 70 and for i 970 80 using i 960 70 as the base the signs of the change in the levels of the gdp and aid mean values between periods are recorded this is repeated for i980 4 with i970 80 mean values as the base the relationship between the two signs is an indication of the effect of aid on gdp in the period in which the change in levels is effected thus in the case of an increase in aid being combined with a decrease in gdp the latter must have fallen relatively to the former and aid effectiveness is negative mutatis mutandis for the other three sign combinations thus generating the appropriate gdp aid relationship for each country in each period a frequency distribution of the four sign combinations relating to the full sample is presented in table i since the signs of the changes in the levels of gdp and aid are derived by making explicit the arithmetic relationship implicit in the data they form a valid base from which to draw conclusions without requiring any test of

foreign aid and government fiscal behaviour in low income south asian countries the major purpose of this study was to analyse the relationship between foreign aid and government fiscal behaviour using a pooled sample of three low income south asian countries pakistan india and sri lanka a simultaneous equation system was developed and estimated using nonlinear three stage least squares procedure the results confirm the hypothesis that foreign aid affects both the expenditure and the revenue side of the recipient government budgets both grants and loans are used for consumption as well as for investment purposes however grants leak into consumption more than loans thus if the purpose of aid is to generate investment it is more helpful if donors extend loans to the developing countries than by giving grants the results also indicate that both grants and loans increase the taxation effort multilateral aid actually pulls resources out of consumption and places them into investment projects thus the results confirm the assertion that a shift from bilateral to multilateral ai

selection on moral hazard in health insurance economic analysis of market failure in insurance markets tends to analyze selection and moral hazard as distinct phenomena in this paper we explore the potential for selection on moral hazard in insurance markets by this we mean the possibility that moral hazard effects are heterogenous across individuals and that individuals selection of insurance coverage is affected by their anticipated behavioral response to coverage we examine these issues empirically in the context of employer provided health insurance in the united states specifically we break down the general

the demand for episodes of treatment in the health insurance experiment abstract this paper analyzes claims data from the rand health insurance experiment which were grouped into episodes of treatment the insurance plans in the experiment have coinsurance and a cap on out of pocket spending using new statistical techniques to adjust for the increased sickliness of those who exceed the cap the effects of coinsurance on cost per episode and number of episodes are estimated cost sharing reduced the number of episodes but had little effect on cost per episode people in the experiment responded myopically as their current insurance status changed through the year the price elasticity of spending was about 0 2 throughout the range of coinsurance studied when data permit it the study of episodes complements analyses of annual medical spending by revealing more about how decisions to spend are made within the year

the macroeconomic impact of development aid a critical survey the early literature explained aid s macroeconomic impact in the context of the dual gap model showing a clear link between aid and growth many now believe that the empirical evidence shows there to be no such relationship this paper critically reviews the different theoretical perspectives the dual gap model the savings debate recipient fiscal response and aid as dutch disease and the empirical debates on aid savings and growth the basis for denying a relationship between aid and growth is shown to be weak though more recent areas of research offer promising directions for future work

estimating welfare in insurance markets using variation in prices we provide a graphical illustration of how standard consumer and producer theory can be used to quantify the welfare loss associated with inefficient pricing in insurance markets with selection we then show how this welfare loss can be estimated empirically using identifying variation in the price of insurance such variation together with quantity data allows us to estimate the demand for insurance the same variation together with cost data allows us to estimate how insurers costs vary as market participants endogenously respond to price the slope of this estimated cost curve provides a direct test for both the existence and the nature of selection and the combination of demand and cost curves can be used to estimate welfare we illustrate our approach by applying it to data on employerprovided health insurance from one specific company we detect adverse selection but estimate that the quantitative welfare implications associated with inefficient pricing in our particular application are small in both absolute and relative terms

is foreign aid fungible evidence from the education and health sectors this paper adopts a new approach to the issue of foreign aid fungibility in contrast to most existing empirical studies panel data are employed that contain information on the specific purposes for which aid is given this allows linking aid that is provided for education and health purposes to recipient public spending in these sectors in addition aid flows that are recorded on a recipient s budget are distinguished from those that are not recorded on budget and the previous failure to differentiate between on and off budget aid is shown to produce biased estimates of fungibility sector program aid is the measure of on budget aid whereas technical cooperation serves as a proxy for off budget aid the appropriate treatment of off budget aid leads to lower fungibility estimates than those reported in many previous studies specifically in both sectors and across a range of specifications technical cooperation which is the largest component of total education and health aid leads to at most a small displacement of recipient public expenditures

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

fiscal effects of foreign aid in a federal system of governance the case of india abstract this paper models fiscal effects of foreign aid in a federal system of governance our main innovation is to incorporate the inter governmental fiscal link in examining economic fungibility of foreign aid the model is applied to the expenditure decisions of the central government of india the two main findings are i foreign aid merely substitutes for spending that the government would have undertaken anyway funds freed by aid are spent on non development activities and ii in passing earmarked external assistance to states the central government makes a reduction in its transfers to states these findings indicate that the central government s expenditure choices are unaffected by external assistance the implication for donors is that even though their development projects may be associated with very high rates of economic return they could be assisting the central government in financing something very different at the margin for the state governments the finding indicates that they may not be reaping the full benefits of externally procured assistance

foreign aid taxes and public investment a comment abstract in a paper recently published in this journal gang and khan 1991 analysed the relationship between foreign aid and the fiscal behavior of the indian government a number of behavioural equations were estimated each derived from a utility maximizing theoretical framework this paper identifies and seeks to correct some inconsistencies in this framework

roads out of poverty assessing the links between aid public investment growth and poverty reduction the authors develop a macroeconomic framework that captures links between aid public investment growth and poverty public investment is disaggregated into education infrastructure and health and affects both aggregate supply and demand dutch disease effects are captured by accounting for changes in the relative price of domestic goods the authors assess the impact of policy shocks on poverty by linking the model to a household survey they calibrate the model for ethiopia and simulate the changes in the allocation of aid and public investment the authors also calculate the amount by which foreign aid should increase to reach the poverty targets of the millennium development goals

patient cost sharing and hospitalization offsets in the elderly in the medicare program increases in cost sharing by a supplemental insurer can exert financial externalities we study a policy change that raised patient cost sharing for the supplemental insurer for retired public employees in california we find that physician visits and prescription drug usage have elasticities that are similar to those of the rand health insurance experiment hie unlike the hie however we find substantial offset effects in terms of increased hospital utilization the savings from increased cost sharing accrue mostly to the supplemental insurer while the costs of increased hospitalization accrue mostly to medicare

adverse selection and inertia in health insurance markets when nudging hurts this paper investigates consumer inertia in health insurance markets where adverse selection is a potential concern we leverage a major change to insurance provision that occurred at a large firm to identify substantial inertia and develop and estimate a choice model that also quantifies risk preferences and ex ante health risk we use these estimates to study the impact of policies that nudge consumers toward better decisions by reducing inertia when aggregated these improved individual level choices substantially exacerbate adverse selection in our setting leading to an overall reduction in welfare that doubles the existing welfare loss from adverse selection jel d82 g22 i13 a number of potential impediments stand in the way of efficient health insur ance markets the most noted of these is adverse selection first studied by akerlof 1970 and rothschild and stiglitz 1976 in insurance markets prices reflect the expected risk costs of the insured pool whether the reason is price regulation or private information when insurers cannot price all risk characteristics riskier consumers choose more comprehensive health plans this causes the equilibrium prices of these plans to rise and healthier enrollees to select less comprehensive coverage than they would otherwise prefer

location matters the impact of renewable power on transmission congestion and emissions abstract many governments offer subsidies for renewable power to reduce greenhouse gas emissions in the power sector however most support schemes for renewable power do not take into account that emissions depend on the location of renewable and conventional power plants within an electricity grid i simulate optimal power flow in a test grid when 4 renewable power plants connect to the grid across 24 potential sites amounting to over 10 000 configurations each configuration is associated with different levels of emissions and renewable power output i find that emission reductions vary by a factor of 7 and that curtailment due to transmission congestion is more likely when renewable power plants are concentrated in an area of the grid with low demand large cost savings could be obtained by allowing subsidies for renewable power to vary across locations according to abatement potential or by replacing subsidies with a price on emissions

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
