Neglected Heterogeneity And Dynamics In Cross Country Savings Regressions

This paper examines the extent to which conclusions of cross-country studies of private savings are robust to allowing for the possible heterogeneity of savings behavior across countries and the inclusion of dynamics. It shows that neglecting heterogeneity and dynamics can lead to misleading inferences about the key determinants of savings behavior. The results indicate that among the many variables considered in the literature only the fiscal variables—the general government surplus as a proportion of GDP and the ratio of government consumption to GDP—are important determinants of private savings rates in the industrial countries in the post-World War II period.

'Beyond Reforms' argues that economic growth in developing countries is intrinsically tied to the dynamics of production structures, to the specific policies and institutions created to support it, and the creation of linkages among domestic firms and sectors. Avoiding macroeconomic instability is also essential. However, macroeconomic stability is not a sufficient condition for growth. The broader institutional context and the adequate provision of education and infrastructure are essential 'framework conditions,' but generally do not play a direct role in bringing about changes in the momentum of economic growth.

Research activity in the IMF emphasizes the links between the organization's policy and operational concerns. The main objectives of research is IMF staff understanding of policy and operational issues relevant to the institution, and to improve the analytical quality of the work prepared for management and the Executive Board and the advice provided to member countries. The scope of research in the IMF is defined by the purposes and functions of the institution. In order to foster innovation and ensure quality control, the IMF makes much of its research available outside the institution and encourages staff to interact with academia and other research organizations through conferences, seminars, and occasional joint research projects. The visiting scholar’s program has also enhanced the quality of research done in the IMF. This program brings in leading members of the economics profession from around the world to assist in the preparation of papers for the Executive Board and to conduct research on IMF-related issues.

The publication surveys the main economic events and developments of 2006 and the first half of 2007 in the light of the region's recent economic performance. The fifty-ninth edition of the survey is aimed to provide further inputs for the economic debates concerning means of promoting a rapid, sustainable growth process capable of creating conditions conducive to an improvement in the living conditionsin the region. It also describes various aspects of the regions economic growth dynamics. The tables provided in the statistical appendix provide ready access to data for recent years and facilitate the creation of spreadsheets. The edition is supplemented by a CD-ROM.

We study the long-run relationship between public debt and growth in a large panel of countries. Our analysis takes particular note of theoretical arguments and data considerations in modeling the debt-growth relationship as heterogeneous across countries. We investigate the issue of nonlinearities (debt thresholds) in both the cross-country and within-country dimensions, employing novel methods and diagnostics from the time-series literature adapted for use in the panel. We find some support for a nonlinear relationship between debt and long-run growth across countries, but no evidence for common debt thresholds within countries over time.

We propose a stress testing framework of credit risk, which analyzes macro-financial linkages, generate consistent forecasts of macro-financial variables, and projects NPL on the basis of such forecasts. Economic contractions are generally associated with increases in non-performing loans (NPL). However, despite the common assumption used in the empirical literature of homogenous impact across banks, the strength of this relationship is often bank-specific, and imposing homogeneity may lead to over or underestimating the resilience of the financial system to macroeconomic woes. Our approach accounts for banks’ heterogeneous reaction to macro-financial shocks in a dynamic context and potential cross-sectional dependence across banks caused by common shocks. An application to Ecuador suggests that substantial heterogeneity is present and that this should be taken into account when trying to anticipate inflections in the quality of portfolio.

This publication sets out an empirical analysis of the impact of economic liberalisation and globalisation on inequality, poverty and development, including recent trends in economic growth, income distribution and global inequalities, and the comparative experiences of countries that have pursued different economic policies.
