The Net Stable Funding Ratio: Impact and Issues for Consideration
Description: As part of Basel III reforms, the NSFR is a new prudential liquidity rule aimed at limiting excess maturity transformation risk in the banking sector and promoting funding stability. The revised package has been issued for public consultation with a plan of making the rule binding in 2018. This paper complements earlier quantitative impact studies by discussing the potential impact of introducing the NSFR based on empirical analysis of end-2012 financial data for over 2000 banks covering 128 countries. The calculations show that a sizeable percentage of the banks in most countries would meet the minimum NSFR prudential requirement at end-2012, and, further, that larger banks tend to be more vulnerable to the introduction of the NSFR. Additionally, by comparing the NSFR to other structural funding mismatch indicators, we find that the NSFR is a relatively consistent regulatory measure for capturing banks’ funding risk. Finally, the paper discusses key policy issues for consideration in implementing the NSFR.

Determinants of Interest Rate Spreads in Solomon Islands
Description: Bank interest rate spreads in Solomon Islands are high by regional standards. This paper examines the determinants of bank interest rates including bank specific, banking sector, macroeconomic, and legal indicators. The results show that the scale of operation, overhead costs, concentration index, and some macroeconomic variables (i.e., monetary policy rates and real growth) significantly influence interest rate margins. The paper particularly focus on the influence of the banking sector structure and finds strong evidence of bank collusion.

The Tax-adjusted Q Model with Intangible Assets: Theory and Evidence from Temporary Investment Tax Incentives
Description: We propose a tax-adjusted q model with physical and intangible assets and estimate it with a self-collected comprehensive database of intangible assets. The presence of intangibles changes the accounting and economic measures of q. We show that when tax changes are temporary, the q model can be estimated by adjusting for the firm’s intangible stock and intangible intensity. We estimate our model using temporary investment tax incentive policies in the United States in the early 2000s. When the q-model accounts for intangible assets, the estimated investment elasticity to tax incentives is generally larger than otherwise. It is also larger for intangible-intensive firms, and increases with firm size.

How to Capture Macro-Financial Spillover Effects in Stress Tests?
Description: One of the challenges of financial stability analysis and bank stress testing is how to establish scenarios with meaningful macro-financial linkages, i.e., taking into account spillover effects and other forms of contagion. We come up with an approach to simulate the potential impact of spillover effects based on the “traditional” design of macro-economic stress tests. Specifically, we examine spillover effects observed during the financial crisis and simulate their impact on banks’ liquidity and capital positions. The outcome suggests that spillover effects have a highly non-linear impact on bank soundness, both in terms of liquidity and solvency.

An Application of the "Fan-Chart Approach" to Debt Sustainability in Post-HIPC Low-Income Countries
Description: We analyse the debt dynamics in countries that benefited from the HIPC/MDRI debt relief initiatives with a view to applying a probabilistic approach to estimating future debt paths for those countries. We extend the probabilistic approach to public debt sustainability analysis (DSA) proposed by Celasun et al. (2006). This required addressing the twin challenges of a the time period that is too short to conduct country-by-country estimations and the presence, suggested by econometric evidence, of a break–point around 2006 in the dynamics of debt accumulation. To overcome the data limitations, we pool the data and estimate a panel VAR, thus taking advantage of the large cross–section. To account for the break–point, while applying a probabilistic approach to forecasting debt paths, we use the post–break–point information so as not to bias the forecasts of debt paths. As an illustration of the approach we apply the methodology to eight countries with different debt profiles.

National Income and Its Distribution
Description: Does the distribution of income within a country become more equal as it grows richer? This paper uses plausibly exogenous variations in trade-weighted world income and international oil price shocks as instruments for within-country variations in countries real GDP per capita to examine this issue for a large sample of advanced and developing countries. Our findings indicate that increases in national income have a significant moderating effect on income inequality: a one percent increase in real GDP per capita, on average, reduces the Gini coefficient by around 0.08 percentage points, a result that is robust across income levels, different time horizons, and alternative estimation techniques. From a policy perspective, our results suggest that education policies that promote equity and help individuals continue on to higher levels of education could help reduce income inequality.

Economic Impact of Selected Conflicts in the Middle East: What Can We Learn from the Past?
Description: Using narrative-based country-case studies, war episodes in the Middle East were examined to assess their economic impact on conflict and neighboring economies. The paper found that conflicts led to a contraction in growth, higher inflation, large fiscal and current account deficits, loss of reserves, and a weakened financial system. Post-conflict recovery depended on the economic and institutional development of the country, economic structure, duration of the war, international engagement, and prevailing security conditions. The net economic impact on neighboring countries varied according to their initial economic conditions, number and income level of refugees they hosted, economic integration, and external assistance.

Ms. Muffet, the Spider(gram) and the Web of Macro-Financial Linkages
Description: The global financial crisis has underscored the importance of understanding macro-financial developments and spillovers in an increasingly interconnected and intricate system. At the IMF, staff is focusing on the linkages between the real economy and the financial sector, as well as the inter-relationships between global and individual-country risks. The Country Financial Stability Map provides an empirical framework for explicitly linking these various aspects of the IMF’s surveillance of its member countries. It identifies potential sources of macro-financial risks particular to a country and also enables an assessment of these risks in a global context through comparisons with the corresponding Global Financial Stability Map from the Global Financial Stability Report. The authors have developed an Excel-based tool (“Ms. Muffet”) to facilitate this analysis, which may be replicated by external users with access to the necessary databases, using the accompanying template.

Small and Medium Size Enterprises, Credit Supply Shocks, and Economic Recovery in Europe
Description: The limited access to bank credit in recent years has increased the pressure on small and medium size enterprises (SMEs), forcing them to scale down investment plans and production. This paper, which explores the macroeconomic implications of this channel, finds evidence that countries with high prevalence of SMEs tended to recover more slowly from the global financial crisis than their peers, implying that the interaction of the economic structure and access to bank financing plays a critical role in episodes of economic recovery. This conclusion is reinforced by a VAR estimation, which demonstrates that a negative credit supply shock applied to SMEs has an adverse effect on economic activity, and this impact is amplified in countries that have a high share of SMEs.

After the Fall: Lessons for Policy Cooperation from the Global Crisis
Description: A crisis is a terrible thing to waste, and nowhere is this truer than in the arena of international economic policy cooperation. With the world facing the largest and most synchronized plunge in output of the postwar era, policy makers banded together to find solutions. This paper looks at the lessons from what did—and did not—occur in the area of policy cooperation since the crisis. Outcomes seem to be weaker over time in areas such as macroeconomic policies, where institutional procedures were less well defined and there were disagreements over spillovers. By contrast, cooperation seems to have been most effective where there was a consensus that such policies could avoid the risk of highly detrimental outcomes and institutional arrangements were more concrete. Principle amongst these was trade, but bank capital buffers, IMF resources, and derivatives exchanges also fall into this category. Lessons for those interested in promoting cooperation seems to be: it may be more fruitful to: focus on the potential for major costs from a lack of cooperation, rather than the minor gains from fuller coordination; strive for more consensus estimated spillovers; convince policy-makers costs of loss of cooperation are large; and focus on building better and more enduring institutional arrangements.
