Nonperforming Loans and Macrofinancial Vulnerabilities in Advanced Economies

We analyze the link between nonperforming loans (NPL) and macroeconomic performance using two complementary approaches. First, we investigate the macroeconomic determinants of NPL in panel regressions and confirm that adverse macroeconomic developments are associated with rising NPL. Second, we investigate the feedback between NPL and its macroeconomic determinants in a panel vector autoregressive (PVAR) model. The impulse response functions (IRFs) attribute to NPL a central role in the linkages between credit market frictions and macrofinancial vulnerability. They suggest that a sharp increase in NPL triggers long-lived tailwinds that cripple macroeconomic performance from several fronts.

Aid and the Dutch Disease in Low-Income Countries: Informed Diagnoses for Prudent Prognoses

This paper demonstrates that the Dutch disease need not materialize in low-income countries that can draw on their idle productive capacity to satisfy the aid-induced increased demand. Diagnoses on, and prognoses for, the Dutch disease should take into account country-specific circumstances to avoid ill-advised policies. The paper emphasizes that using public resources inefficiently can be more painful than real exchange rate appreciations, which may not necessarily embody the Dutch disease.

Local Financial Development and the Aid-Growth Relationship

With official development assistance (ODA) set to rise as countries strive to meet the Millennium Development Goals (MDGs), aid effectiveness remains an important area of development policy. An increasing number of studies support the notion that ODA can contribute to growth in a nonlinear relationship. In this paper, we investigate a new hypothesis regarding this relationship: that deeper financial markets in aid-recipient countries facilitate the management of aid flows, thereby enhancing aid effectiveness. An empirical analysis, using a panel data set, finds robust support for the hypothesis.

Financing Uganda'S Poverty Reduction Strategy; Is Aid Causing More Pain Than Gain?

Ugandas market-friendly development strategy and poverty reduction agenda have attracted large financial inflows, including aid. During 2000-02, concerns about a possible aid-induced Dutch disease were heightened by widening macroeconomic imbalances and an upward trend in the real effective exchange rate (REER). This paper shows that the REER remained broadly stable during a 10-year period and nontraditional exports increased remarkably, contrary to the predictions of the Dutch disease model. Also, economic growth was strong. This good performance is attributed to sound macroeconomic policies and important structural reforms, which have allowed an increased use of available production factors.

Boosting Competitiveness to Grow Out of Debt Can Ireland Find a Way Back to its Future

This paper investigates the prospects for Ireland to grow its economy against the backdrop of high indebtedness. The paper uses vector autoregressive analysis to explore the interlinkages among competitiveness, exports, economic growth, and fiscal performance. The emerging conclusion is that Ireland, which has regained cost competitiveness following the crisis-driven fall in domestic prices, is poised to return to its path of strong exports and economic growth and lower imbalances provided that it maintains competitiveness, though a pickup in external demand is critical. Three main findings underpin this conclusion. First, external demand is an important driver of exports and also the single most important determinant of Irelands GDP and government revenue. Second, declines in price competitiveness, featured by real effective exchange rate (REER) appreciations, restrain exports and economic growth. Third, exports boost output, which in turn enhances fiscal performance.

Interest Rates, Credit Rationing, and Investment in Developing Countries

This paper examines the impact of interest rates and inflation on bank loans and investment within a framework that mimics the financial sectors prevailing in most low-income developing countries. The paper emphasizes the importance of treating the lending and deposit rates of interest as distinct parameters in investment equations. The spread between the two rates is indicative of default risk and has a negative impact on incremental loan amounts associated with higher lending rates, in particular in economies with flawed institutions. The model presented in the paper highlights the importance of promoting macroeconomic stability and upgrading institutions and informational infrastructure.
