Institution:
United Nations University
Abstract:
The paper performs aid allocation analysis using OECD-DAC data covering 20 aid donors and 176 recipients over the period 1980-2003. We improve upon earlier work in this area by employing inter alia the variable 'past outcome' measuring aid effectiveness in order to link together aid allocation and aid effectiveness. In line with previous work, we also account for both altruistic and selfish donor motives in the empirical analysis. As expected, empirical results based on To bit estimates of aid allocation for individual donors vary quite significantly among donors. We also test the robustness of our results by estimating individual regressions for the major donors over the period 1990-2003 in view of major events in the aid arena during that time that could potentially have an impact on the aid allocation process. Our results seem to be similar to those derived over the 1980-2003 period, thus implying that this was not the case. Overall, both altruistic and selfish donor motives seem to motivate aid allocation for most donors over the two periods under examination. However, when we further restrict our time dimension to the 1999-2003 period, some important policy changes with regard to selectivity seem to emerge for a small group of donor countries.

2. On the Empirics of Aid and Growth: A Fresh Look

Abstract:
The paper contributes to the empirics of aid and growth by taking a fresh look at the aid-policies-growth nexus emanating from the very influential but also debatable paper on the subject by Burnside and Dollar: 'Aid, Policies and Growth'. We employ three different datasets (including the one used in the Burnside and Dollar paper) and Bayesian instrumental variable methods to test the robustness of the central finding of the Burnside and Dollar paper related to the aid and policy interaction coefficient. In doing so, we applied Bayesian instrumental variable technique s to find the most probable parameter values in the growth equation. We also test for the exogeneity of the instrumental variables used. We find that the marginal effect of the disputed (Aid/GDP) x Policy variable on real per capita GDP growth is substantially smaller than in Burnside and Dollar, thus casting serious doubts on the robustness of their findings, and most importantly, on the validity of the policy lessons emerged from the Burnside- Dollar study.

3. The Poverty Macroeconomic Policy Nexus: Some Short-run Analytics

Author:

Working Paper
Institution:
United Nations University
Abstract:
The present paper utilises a short-run theoretical macroeconomic model of a small open economy to look at the impact of macroeconomic policies and financial deepening upon poverty through sectoral changes. This is because an expansion in certain sectors may cause greater poverty reduction. The model involves a non-traded and a traded sector on the formal side of the economy. The former is more capital intensive and the latter more unskilled labour intensive. Increased employment in the traded sector is more pro-poor compared to a similar rise in the non-traded sector as the former draws workers out of poverty in the informal sector. The model in our paper analyses short-run effects of devaluation, a rise in the money supply induced by financial deepening, and taxation to discourage non-traded goods consumption. Financial deepening can induce greater output and reduce poverty. Other results are mixed and taxonomic. We also attempt to differentiate between the stylised experiences of East Asia and Latin America. East Asian economies have relied more heavily on labour-intensive manufactured exports, whereas Latin America has had a relatively greater share of capital intensive and natural resource based exports. In recent decades countries in these two regions have had differing experiences in poverty reduction, with poverty arguably declining more in East Asia.

4. Education, Financial Institutions, Inflation and Growth

Abstract:
Our paper investigates the unexplored impact of education on inflation and of this relationship on economic growth. By using a sample of 102 countries observed on non-overlapping five-year data spells over the period 1963-2001, we find that average schooling years of the working population have a significant negative impact on inflation rates after controlling for the effects of the stance of domestic monetary policy. We also show that the negative impact of inflation on growth in conditional convergence estimates is significantly increased when the former is instrumented by educational variables. Our findings outline a third potential role of human capital on conditional convergence. They show that education is not only a production factor or a variable which may reduce demographic pressures, but also an important antidote against inflationary pressures which, in turn, negatively affect economic growth and conditional convergence. We interpret our findings by identifying three potential rationales for the education-inflation nexus: (i) education raises consumers' awareness of their power in contrasting producers' inflationary pressures; (ii) more educated individuals have lower inflationary expectations when they are also wealthier and their consumption bundle is relatively less (more) intensive in inferior (superior) goods with higher (lower) inflation potential; (iii) more (less) educated and wealthier (less wealthy) individuals tend to be net creditors (debtors) in their maturity, thereby contributing to increase (reduce) the power of anti-inflationary lobbies.

5. Financial Sector Development and Productivity Growth

Abstract:
Recent years have witnessed important structural changes around the world as a result of the globalization process, the creation of new economic blocks and the liberalization of financial sector in many countries. Responding to these changes many sectors of the industrialized countries have gone through major deregulatory changes to acclimate themselves to new environments. At the same time, many countries have undertaken institutional reforms to build a market-orientated financial system in the hope that transition towards market economy will improve productivity. In the face of uncertainty resulting from changes in regulatory structure and the development of financial institutions to foster market economy, many countries may not be able to achieve their maximum growth potential. In other words, productivity growth is likely to depend on the development of financial institutions and the stage of economic development That is, a less developed country is likely to benefit more (in terms of output growth rate) from the development of financial institutions than a developed economy with well-developed financial system. In this paper we document this by using data covering 65 countries, varying substantially in term s of level of development and geographic location, and spanning the period 1960-1999. Empirical results obtained from the estimation of two different empirical models regarding the measurement of total factor productivity growth seem to confirm a priori expectations about the overall positive influence of financial systems on productivity in line with previous work on this front. Our results remain robust with respect to alternative definitions of financial sector development we tried.

6. Financial Sector Structure and Financial Crisis Burden: A Model Based on the Russian Default of 1998

Author:

Working Paper

Abstract:
We consider an overlapping generations model with two production factors and two types of agents in the presence of financial intermediation and its application to the Russian default of August 1998. The paper focuses on the analysis of the consequences of a sudden negative repayments shock on financial intermediation capacity and consequently on the economy as a whole. The model exhibits a 'chain reaction' property, when a single macroeconomic shock can lead to the exhaustion of credit resources and to the subsequent collapse of the whole banking system. To maintain the capability of the system to recover, regulatory intervention is needed even in the presence of the state guarantees on agents' deposits in the banks (workout incentives). We compare the results for an intermediated economy with those derived under the assumption of a market economy, and draw some broad conclusions on the consequences of the crises, which are contingent on the financial sector structure.

7. The Volatility of Aid

Abstract:
Issues related to the volatility of aid flows are now becoming crucial in view of their relevance to the achievement of the Millennium Development Goals. The paper examines aid volatility using data for 66 aid recipients over the period 1973-2002. We improve upon earlier work in this important area by disaggregating total aid inflows into sector and programme aid. In this way we avoid focussing on a single aggregate, unlike most previous studies on aid volatility. We also adopt a different methodology to capture aid volatility. The institutional quality of the aid recipient affects the stability of sector aid but not that of programme assistance. Moreover, more open economies, which tend to be smaller and richer, ceteris paribus, are associated with more volatile sector aid flows.

8. A Contract Perspective on the International Finance Facility

Working Paper
Institution:
United Nations University
Abstract:
The present paper is a first attempt to develop a theoretical model using a short-term vis-á-vis long-term contract framework within which donor countries' endorsement or rejection decision towards the recently proposed International Finance Facility (IFF) is rationalized. The current foreign aid system is portrayed as being similar to a series of short-term contracts, where donor countries are able to adjust the aid amount to reflect environmental change (broadly defined to take into account changes in public opinion, domestic situation, etc.). The benefit of this system is in its flexibility. Frontloading aid, on the other hand, as proposed by the IFF proposal, has the benefit of smoothing out the flows over time. In the model presented in this paper, donor countries balance these two contract schemes to determine the endorsement or rejection of the IFF proposal. By using historical aid data covering the period 1990-2003 for all DAC donor countries, our empirical analysis shows the payoffs and relative advantages of these two contract schemes.

9. Which Types of Aid Have the Most Impact?

George Mavrotas
Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
The paper uses an aid disaggregation approach to examine the impact of different types of aid on the fiscal sector of the aid-recipient country. It uses time-series data on different types of aid (project aid, programme aid, technical assistance and food aid) for Uganda, an important aid recipient in recent years, to estimate a model of fiscal response in the presence of aid which combines aid disaggregation and endogenous aid. The empirical findings clearly suggest the importance of the above approach for delving deeper into aid effectiveness issues since different aid categories have different effects on key fiscal variables—an impact that could not be revealed if a single figure for aid was employed. More precisely, project aid and food aid appear to cause a reduction in public investment whereas programme aid and technical assistance are positively related to public investment. The same applies for government consumption. A negligible impact on government tax and non-tax revenues, and a strong displacement of government borrowing are also found.

10. Loan Processing Costs and Information Asymmetries - Implications for Financial Sector Development and Economic Growth

Author:
George Mavrotas and Salvatore Capasso
Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
The paper presents a model in which credit-constrained firms might delay the adoption of new and more productive technologies because of the very high external financing costs they face. Our point of departure is that the efficiency of the banking system can have a profound impact on real resource and investment allocation not only directly, by reducing the amount of resources channelled to the credit market, but also indirectly by affecting entrepreneurs' investment decisions. Along these lines of reasoning we develop a model of information asymmetries in the credit market in which high costs of processing bank loan applications might obstruct investments in high-tech projects and favour, instead, low-return, self-financed investments in mature sectors. The result is that these kinds of costs have a negative impact on the average capital productivity and on the rate of economic growth. In specific circumstances, the combination of these costs and the dynamics of capital accumulation can be such that the economy incurs in a 'technology trap', in which new technologies, even if readily available, will never be adopted because of high frictions and inefficiencies in the credit market, a situation that seems to be relevant to many developing countries.
