Although central banks have recently taken unconventional policy actions to try to shore up macroeconomic and financial stability, little theory is available to assess the consequences of such measures. This paper offers a theoretical model with which such policies can be analyzed. In particular, the paper shows that in the absence of the fiscal authorities' full backing of the central bank's balance sheet, strange things can happen. For instance, an exit from quantitative easing could be inflationary and central banks cannot successfully unwind inflated balance sheets. Therefore, the fiscal authorities' full backing of the monetary authorities' quasi-fiscal operations is a pre-condition for effective monetary policy.

This book brings together new research on three areas of ongoing interest in the area of international finance such as: Inflation, Fiscal Policy and Central Policy. Several of the papers deal with the G-8 countries.

Central banks and other public financial institutions act as agents of fiscal policy in many countries. Their "quasi-fiscal" operations and activities can affect the overall public sector balance without affecting the budget deficit as conventionally measured, may also have important allocative effects, and increase the effective size of the public sector. This paper analyzes the macroeconomic and financial effects of such quasi-fiscal activities, as well as the taxes, subsidies, and other expenditures that such activities introduce outside the budget. Measurement and accounting issues are addressed, and policy recommendations are offered.

Central bank financial strength is positively associated with good policy performance. Financially weak central banks generate losses which undermine macroeconomic stability and call into question the credibility of their policies. In assessing central bank financial strength a careful examination of the policy regime and the volatility of the economic environment is necessary. Conventional measures of private enterprise financial strength- profitability and capital-can be very misleading when applied to central banks. The way in which a central bank balance sheet is strengthened matters. Providing the central bank with marketable government debt that can be used to develop a money market that in turn may become the locus of central bank monetary operations serves both to directly strengthen the institution and improve the quality of the environment in which it operates, thereby facilitating the attainment of its ultimate performance objectives.

This paper reviews issues associated with quasi-fiscal operations (QFO) of central banks in a sample of countries in Central and Eastern Europe and the former Soviet Union. The concern is the problem of transparency in fiscal and monetary accounts when the central bank undertakes quasi-fiscal operations and the government falls short of providing full coverage of fiscal operations. QFO can also jeopardize monetary policy designed to maintain price stability. A simple framework is developed to estimate the extent of QFO. In some cases, the magnitude of QFO is significant in indicating underestimation of fiscal deficit figures. We claim that the lack of transparency in fiscal accounts of transition countries warrants serious concern.

Zimbabwe's failure to address continuing central bank quasi-fiscal losses has interfered with both monetary management and the independence and credibility of the Reserve Bank of Zimbabwe (RBZ). Realized quasi-fiscal losses are estimated to have amounted to about 75 percent of GDP in 2006. Because they were financed by creating money creation or issuing RBZ securities, they contributed to the four-digit inflation reached in 2006. The remedy for the current situation is clearly to eliminate the causes of losses by implementing measures to improve the cash-flow of the bank and restore its financial position.
