Beyond capital ideals : restoring banking stability

The authors examine why emerging markets, in particular, are susceptible to and affected by financial difficulties. They show that these difficulties have a richer, more complex structure than they are sometimes believed to have - with marked information asymmetries and substantial volatility. The sources of heightened regulatory failure in emerging markets in recent years include the volatility of real and nominal shocks, the difficulty of operating in uncharted territory after financial liberalization and other changes in regime, and the political pressures that can inhibit the enforcement of prudential regulation. The authors discuss what stronger regulation can and cannot accomplish, as well as options to improve the incentive structure for bankers, regulators, and other market participants. They probe the shortcomings of a regulatory paradigm that relies mainly on supervised capital adequacy and discuss the possible intermittent application of supplementary"blunt instruments"as an interim solution while longer-term reforms are being put in place. Certain well-worn messages remain valid, but are respected more in theory than in practice. There would be fewer problems, the authors say, if there were: 1) more diversification; 2) more balanced financial structures (for example, as between debt and equity); 3) more foreign banks in emerging markets'financial systems; and 4) better enforcement of both contracts and regulations. Participants in the financial sector will constantly try to get around rules that limit their profitability, so regulation must be seen as an evolutionary struggle. Prevention of financial failure is not costless, and a heavy repressive hand is not warranted. But a richer regulatory palette can be used to protect financial systems more successfully against crisis while preserving the systems'growth-enhancing effectiveness.Environmental Economics&Policies,Payment Systems&Infrastructure,Financial Intermediation,Banks&Banking Reform,Financial Crisis Management&Restructuring,Economic Theory&Research,Banks&Banking Reform,Financial Intermediation,Financial Crisis Management&Restructuring,Environmental Economics&Policies

Banking policy and macroeconomic stability - an exploration

Whether and when does banking serve to stabilize the economy? The authors view the banking system as a filter through which foreign and domestic shocks feed through to the domestic economy. The filter can dampen or amplify the shocks through various credit market channels, including credit growth, import of foreign capital, and possibly interest rates. The question is whether the prudential quality of banking, as proxied by measures of regulatory quality and openness to foreign banking, amplify or dampen these shocks. The authors find that many of the regulatory characteristics that have been found to deepen a financial system and make it more robust to crises-notably those which empower the private sector-also appear to reduce the sector's ability to provide short-term insulation to the macro-economy. It is as if prudent bankers are reluctant to absorb short-term risks that, if neglected, might cause solvency and growth problems in the longer run. Forbearance might dampen short-term volatility, but at the expense of the longer run health of the banking sector and the economy. One way to avoid this apparent tradeoff is evident: banking systems which have a higher share of foreign-owned banks, a feature already associated with financial deepening and lowered risk of crisis, also seem to score well in terms of short-term macroeconomic insulation.Payment Systems&Infrastructure,Financial Intermediation,Financial Crisis Management&Restructuring,Banks&Banking Reform,Economic Theory&Research,Banks&Banking Reform,Financial Intermediation,Financial Crisis Management&Restructuring,Economic Theory&Research,Settlement of Investment Disputes

Banking Crises

The history of banking around the world has been punctuated by frequent systemic crises. Not all crises are the same with distinct roles being played at different times by mismanagement, government interference and macroeconomic shocks. This review draws on experience from developing countries as well as advanced economies. It identifies common features of crises in recent decades, describes how costly they have been (especially in developing countries) in terms of fiscal burden and impact on macroeconomic growth. It proceeds to outline the conceptual issues identified by theoreticians and considers appropriate policy responses. A lull in the new millennium led to optimism that banking crises might be a thing of the past, but the events of recent months have shown such optimism to be unwarranted.

An analytically linearized helicopter model with improved modeling accuracy

An analytically linearized model for helicopter flight response including rotor blade dynamics and dynamic inflow, that was recently developed, was studied with the objective of increasing the understanding, the ease of use, and the accuracy of the model. The mathematical model is described along with a description of the UH-60A Black Hawk helicopter and flight test used to validate the model. To aid in utilization of the model for sensitivity analysis, a new, faster, and more efficient implementation of the model was developed. It is shown that several errors in the mathematical modeling of the system caused a reduction in accuracy. These errors in rotor force resolution, trim force and moment calculation, and rotor inertia terms were corrected along with improvements to the programming style and documentation. Use of a trim input file to drive the model is examined. Trim file errors in blade twist, control input phase angle, coning and lag angles, main and tail rotor pitch, and uniform induced velocity, were corrected. Finally, through direct comparison of the original and corrected model responses to flight test data, the effect of the corrections on overall model output is shown

Amputation in emergency situations: indications, techniques and Médecins Sans Frontières France's experience in Haiti

PURPOSE: The decision to amputate is always difficult but becomes even harder in emergency situations, which usually present extra complicating factors. MSF EXPERIENCE: These include human factors (related to both the surgeon and the patient); poor or nonexistent medical facilities, especially in war conditions or resource-poor countries; and cultural and religious considerations. Médecins Sans Frontières (MSF) has developed a quick medical and logistical response that relies on surgical protocols adapted to emergency situations, together with complete "kits" of medical equipment, supplies and inflatable facilities. CONCLUSION: Our response to Haiti's 2010 earthquake relied on these tools but also highlighted the need to develop more detailed protocols that will help our teams on the ground
