Household Saving in Developing Countries: First Cross-Country Evidence

Although most studies have relied on domestic or private sectorsaving data, this article uses household data available fromthe U.N. System of National Accounts for a sample of 10 countries.Household saving functions are estimated using combined time-seriesand cross-country observations in order to test households'responses to income and growth, rates of return, monetary wealth,foreign saving, and demographic variables. The results showthat income and wealth variables affect saving strongly andin ways consistent with standard theories. Inflation and theinterest rate do not show clear effects on saving, which isalso consistent with their theoretical ambiguity. Foreign savingand monetary assets have strong negative effects on householdsaving, which suggests the importance of liquidity constraintsand monetary wealth in developing countries.     

Saving in Developing Countries: An Overview

This article reviews the current state of knowledge on the determinantsof saving rates, presenting the main findings and contributionsof the recently completed World Bank research project, ‘SavingAcross the World.’ The article discusses the basic designof the research project and its core database, the World SavingDatabase. It then summarizes the main project results and placesthem in the context of the literature on saving, identifyingthe key policy and nonpolicy determinants of private savingrates. Special attention is paid to the relationship betweengrowth and saving and the impact of specific policies on savingrates. The article concludes by introducing the studies includedin this special issue.     

Macroeconomic policies and performance in Latin America

This paper provides new evidence on macroeconomic policies and results in Latin America and the Caribbean. Results are: (i) credibility allows adoption of counter-cyclical macroeconomic policies; (ii) accuracy in meeting inflation targets depends on central bank independence and country risk; (iii) intermediate exchange rate (ER) regimes have become less persistent; (iv) ER regimes matter for inflation and growth; (v) real ER trends are not explained by productivity growth and supply reforms do not resolve real ER misalignments; (vi) financial integration has increased significantly; (vii) foreign shocks are a major growth determinant; and (viii) composition of foreign capital inflows matters for growth.     

FISCAL DEFICITS AND MACROECONOMIC PERFORMANCE IN DEVELOPING COUNTRIES

Although fiscal adjustment was urged on developing countriesduring the 1980s to lead them out of economic malaise, considerableuncertainty remains about the relations between fiscal policyand macroeconomic performance. To illustrate how financial markets,private spending, and the external sector react to fiscal policies,the behavior of holdings of money and public debt, private consumptionand investment, the trade balance, and the real exchange rateis modeled for a sample of ten developing countries. The studiesfind strong evidence that over the medium term, money financingof the deficit leads to higher inflation, while debt financingleads to higher real interest rates or increased repressionof financial markets, with the fiscal gains coming at increasinglyunfavorable terms. Consumers respond differently to conventionaltaxes, unconventional taxes (through inflation or interest andcredit controls), and debt financing, in ways that make fiscaladjustment the most effective means of increasing national saving.Private investment—but not private consumption—issensitive to the real interest rate, which rises under domesticborrowing to finance the deficit. Contrary to the popular presumption,in some countries private investment increases when public investmentdecreases. There is strong evidence that fiscal deficits spillover into external deficits, leading to appreciation of thereal exchange rate. Fiscal deficits and growth are self-reinforcing:good fiscal management preserves access to foreign lending andavoids the crowding out of private investment, while growthstabilizes the budget and improves the fiscal position. Thevirtuous circle of growth and good fiscal management is oneof the strongest arguments for a policy of low and stable fiscaldeficits.      

Foreign Aid, the Real Exchange Rate, and Economic Growth in the Aftermath of Civil Wars

Foreign aid, the real exchange rate (RER), and economic growthare three key variables that shape the aftermath of civil warsin many developing countries. Panel estimations drawn from asample of 39 conflict and 44 nonconflict countries between 1970and 2004 indicate that although postconflict countries receivelarger aid flows and exhibit moderate RER overvaluation afterpeace is attained, overvaluation cannot be traced to aid. Yetforeign aid is among the significant determinants of the equilibriumRER. Aid is also an important determinant of economic growth,particularly after peace is reached. Aid exhibits decreasingreturns, however, and interacts negatively with RER overvaluation.RER overvaluation reduces growth, but this effect is amelioratedby financial development. Postconflict policies should thereforeaim to use aid prudently, avoid RER misalignment, and supportfinancial and capital market development to achieve high andstable growth in the aftermath of war and beyond.     

A systemic approach to modelling and estimating demand for money(ies)

This article uses a consumer theory-based systemic approach to model the demand for monetary liquid asset holdings in Chile. We implement the suggestions and caveats of aggregation theory for the estimation of a demand system for liquid assets (monies) in static, dynamic and time-varying parameters setups. Our results are robust and theoretically consistent with consumer theory restrictions, as a system derived from a utility maximizing framework and a quasi concave utility function. In our estimations, we find stability of interest rate elasticities, in contrast to previous related literature. We also document evidence that long (short) maturity rates are associated to less (more) liquid assets.     

Comments on S. Edwards: “Monetary unions, external shocks and economic performance: a Latin American perspective”

I discuss Sebastian Edwards’ most recent paper with great pleasure. As so much of the work of this distinguished economist, this paper provides new insights on a burning issue in international economics. Here Edwards provides empirical evidence on the resilience to external shocks of countries that lack a national currency (“monetary-union” or MU countries). The paper starts by reviewing the issues and literature relevant on exchange-rate regimes, dollarization, and MU in Latin America, with an emphasis on the question if countries in the region satisfy key optimal currency area criteria. Then the paper provides extensive new evidence on economic performance in MU countries, in comparison to countries with a national currency, using a large world panel sample. Performance tests are conducted for the comparative likelihood of MU countries of sudden stops in capital flows (SS) and large current (deficit) reversals (CAR), as well as their ability to absorb terms-of-trade shocks, SS, and CAR. The results are generally negative and significant for the comparative performance of MU countries. To set the stage, I start my comments by documenting first how country selection of exchange-rate and monetary regimes is quickly evolving in the world during the last decades, discussing subsequently how economists’ views follow suit (Section 1). Then I discuss some aspects of Edwards’ paper, focusing in particular on the data and model specification (Section 2). I end with brief implications for exchange-rate and monetary regime choice in Latin America.     

SAVING AND INVESTMENT: PARADIGMS, PUZZLES, POLICIES

The 1990s have seen a renewed interest in issues of capitalaccumulation and growth. New paradigms for saving, investment,and growth have been advanced to address theoretical and empiricalpuzzles and to guide the design of better policies. This paperprovides a policy-oriented review of recent theoretical andempirical work on the determinants of saving and investmentand on their links to growth. It takes stock of new findingsas well as still unresolved questions and gives particular attentionto empirical regularities and to the policy issues relevantto developing countries.
