Monetary Operations and Islamic Banking in the GCC: Challenges and Options

Description: The assessment provides evidence of market segmentation across Islamic and conventional banks in the Gulf Cooperation Council (GCC), leading to excess liquidity, and an uneven playing field for Islamic banks that might affect their growth. Liquidiy management has been a long-standing concern in the global Islamic finance industry as there is a general lack of Shari’ah compliant instruments than can serve as high-quality short-term liquid assets. The degree of segmentation and bank behavior varies across countries depending on Shari’ah permissibility and the availability of Shari’ah-compliant instruments. A partial response would be to support efforts to build Islamic liquid interbank and money markets, which are crucial for monetary policy transmission through the Islamic financial system.This can be achieved, to a large extent, by deepening Islamic government securities and developing Shari’ah-compliant money market instruments.

Monetary Policy Transmission and Financial Stability in a LIC: The Case of Bangladesh

Description: This paper explores how monetary policy affects the real economy and its efficacy in promoting financial stability in a large low income country. This paper shows that monetary policy modestly impacts real economic activity and inflation via the bank lending and financial accelerator channels. Second, money market and treasury rates signal changes in the policy stance, while altering banks’ intermediation cost curves due to shifting risk premia. At the same time, evidence points to monetary policy inducing an overshooting in asset prices. These findings suggest that financial stability could be undermined if the calibration of monetary policy is based solely on output and inflation without accounting for the stage of the financial cycle. Finally, the paper discusses policy measures that would enhance the transmission of monetary policy and promote financial stability in Bangladesh.

Inflation and Activity – Two Explorations and their Monetary Policy Implications

Description: We explore two issues triggered by the crisis. First, in most advanced countries, output remains far below the pre-recession trend, suggesting hysteresis. Second, while inflation has decreased, it has decreased less than anticipated, suggesting a breakdown of the relation between inflation and activity. To examine the first, we look at 122 recessions over the past 50 years in 23 countries. We find that a high proportion of them have been followed by lower output or even lower growth. To examine the second, we estimate a Phillips curve relation over the past 50 years for 20 countries. We find that the effect of unemployment on inflation, for given expected inflation, decreased until the early 1990s, but has remained roughly stable since then. We draw implications of our findings for monetary policy.

Employment and the Great Recession: The Role of Real Wages

Description: This paper argues that the sharp increase in unemployment in a number of advanced countries during the Great Recession was not just cyclical (the result of a lack of aggregate demand); the degree of adjustment of real wages and the impact this had on labor productivity also played a role. In many countries, post-2007 employment losses were modest, as real wages adjusted when the economy slowed down. But in some countries real wage growth stayed too high for too long. The result was large-scale labor shedding, which boosted labor productivity but also contributed to a sharp rise in unemployment. In this context, the paper discusses the different experiences of the UK (where employment increased) and Spain (where it fell sharply), and finds that almost two thirds of the employment losses in Spain resulted from the failure of real wages to adjust adequately.

Inflation Targeting and Exchange Rate Regimes in Emerging Markets

Description: This paper investigates the effects of the adoption of inflation targeting (IT) on the choice of exchange rate regime in emerging markets (EMs), conditional on certain macroeconomic conditions. Using a large sample of EMs and after controlling for the selection bias associated with the adoption of IT, we find that IT countries on average have a relatively more flexible exchange rate regime than other EMs. However, the flexibility of the exchange rate regime shows strong heterogeneity among IT countries depending on their degree of openness and exposure to FX risks. Moreover, we find that the marginal effect of IT adoption on the exchange rate flexibility increases with the duration of the IT regime in place, and with the propensity scores to adopt it.

Macrofinancial Analysis in the World Economy: A Panel Dynamic Stochastic General Equilibrium Approach

Description: This paper develops a structural macroeconometric model of the world economy, disaggregated into forty national economies. This panel dynamic stochastic general equilibrium model features a range of nominal and real rigidities, extensive macrofinancial linkages, and diverse spillover transmission channels. A variety of monetary policy analysis, fiscal policy analysis, macroprudential policy analysis, spillover analysis, and forecasting applications of the estimated model are demonstrated. These include quantifying the monetary, fiscal and macroprudential transmission mechanisms, accounting for business cycle fluctuations, and generating relatively accurate forecasts of inflation and output growth.

Are Capital Inflows Expansionary or Contractionary? Theory, Policy Implications, and Some Evidence

Description: The workhorse open-economy macro model suggests that capital inflows are contractionary because they appreciate the currency and reduce net exports. Emerging market policy makers however believe that inflows lead to credit booms and rising output, and the evidence appears to go their way. To reconcile theory and reality, we extend the set of assets included in the Mundell-Fleming model to include both bonds and non-bonds. At a given policy rate, inflows may decrease the rate on non-bonds, reducing the cost of financial intermediation, potentially offsetting the contractionary impact of appreciation. We explore the implications theoretically and empirically, and find support for the key predictions in the data.

Fiscal Consequences of Terrorism

Description: This paper provides an empirical analysis of how the frequency and severity of terrorism affect government revenue and expenditure during the period 1970–2013 using a panel dataset on 153 countries. We find that terrorism has only a marginal negative effect on tax revenue performance, after controlling for economic and institutional factors. This effect is also not robust to alternative specifications and empirical strategies. On the other hand, we find strong evidence that terrorism is associated with an increase in military spending as a percent of GDP (and a share of total government expenditure). Our estimations reveal that this impact is greater when terrorist attacks are frequent and result in a large number of fatalities. Empirical findings also support the view that public finances in developing and low-income countries are more vulnerable to terrorism than those in countries that are richer and diversified.

Breaking Through the Zero Lower Bound

Description: There has been much discussion about eliminating the “zero lower bound” by eliminating paper currency. But such a radical and difficult approach as eliminating paper currency is not necessary. Much as during the Great Depression—when countries were able to revive their economies by going off the gold standard—all that is needed to empower monetary policy to cut interest rates as much as needed for economic stimulus now is to change from a paper standard to an electronic money standard, and to be willing to have paper currency go away from par. This paper develops the idea further and shows how such a mechanism can be implemented in a minimalist way by using a time-varying paper currency deposit fee between private banks and the central bank. This allows the central bank to create a crawling-peg exchange rate between paper currency and electronic money; the paper currency interest rate can be either lowered below zero or raised above zero. Such an ability to vary the paper currency interest rate along with other key interest rates, makes it possible to stimulate investment and net exports as much as needed to revive the economy, even when inflation, interest rates, and economic activity are quite low, as they are currently in many countries. The paper also examines different options available to the central bank to return to par when negative interest rates are no longer needed, and the associated implications for the financial sector and debt contracts. Finally, the paper discusses various legal, political, and economic challenges of putting in place such a framework and how policymakers could address them.

Dealing with Systemic Sovereign Debt Crises: Fiscal Consolidation, Bail-ins or Official Transfers?

Description: The paper presents a tractable model to understand how international financial institutions (IFIs) should deal with the sovereign debt crisis of a systemic country, in which case private creditors' bail-ins entail international spillovers. Besides lending to the country up to its borrowing capacity, IFIs face the difficult issue of how to address the remaining financing needs with a combination of fiscal consolidation, bail-ins and possibly official transfers. To maximize social welfare, IFIs should differentiate the policy mix depending on the strength of spillovers. In particular, stronger spillovers call for smaller bail-ins and greater fiscal consolidation. Furthermore, to avoid requiring excessive fiscal consolidation, IFIs should provide highly systemic countries with official transfers. To limit the moral hazard consequences of transfers, it is important that IFIs operate under a predetermined crisis-resolution framework that ensures commitment.
