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.

Fragilities in the U.S. Treasury Market: Lessons from the “Flash Rally” of October 15, 2014
Description: Changes in the structure of the U.S. Treasury market over recent years may have increased risks to financial stability. Traditional market makers have changed their liquidity provision by increasingly switching from risk warehousing to risk distribution, and a new breed of market maker has emerged with the rise of electronic trading. The “flash rally” of October 15, 2014 provides a clear example of how those risks can materialize. Based on an in-depth analysis of the event—complementing the authorities’ work—we suggest i) providing incentives for liquidity provision, ii) improving market safeguards, and iii) enhancing the regulation of the Treasury market.

Spillovers from China onto Sub-Saharan Africa: Insights from the Flexible System of Global Models (FSGM)
Description: What is the impact of economic spillovers from China on sub-Saharan Africa (SSA)? This is an increasingly important question because of China’s growing economic role as a partner of SSA countriesfor both trade and the buildup of infrastructure in the region. The impact of spillovers from China has been an open question because of the challenge to use an internally consistent framework with solid economic foundations that accounts for both the direct impact China may have on individual countries in SSA through a variety of channels (trade, investment, financial) as well as the impact on the region through the global economy (economic activity and commodity prices). This paper explores those channels of transmission and provides illustrative order of magnitude for the short- and medium-term economic impact by using AFRMOD, a module of the Flexible System of Global Models (FSGM), a multicountry general equilibrium model developed at the IMF. Three alternative scenarios are considered: first, lower potential output in China that is originally misperceived as a temporary cyclical slowdown; second, structural reforms in China that aim to increase potential output; and third, a relocation of low-end manufacturing to sub-Saharan Africa.

A Financial Conditions Index for Greece
Description: We construct a Financial Conditions Index (FCI) for Greece as a surveillance tool to quantify the degree of the stress in the financial sector. We use principal component analysis to capture the information content of several financial indicators through a single index. We also construct an alternative FCI by purging the business cycle and monetary policy effects on the input variables, and argue that this alternative index is a better indicator of exogenous financial shocks, and thus could be interpreted as a measure of the efficacy of transmission mechanism. We replicate the index for the euro area (EA) as a whole and show that although the developments in the EA were qualitatively in line with those in Greece, they were quantitatively much milder. Our results confirm that monetary transmission was less effective in Greece compared to the EA as a whole. Finally, we argue that our index can be a potentially useful forecasting tool for credit growth.

Emerging Powers and Global Governance: Whither the IMF?
Description: The governance structure in global bodies like the IMF continues to be disproportionally dominated by advanced economies. Sustained rapid growth in emerging and developing economies (EDEs) in the past 2-3 decades has led to their growing relative weight in the global economy, but with little increase in their voice in the IMF. The emergence of regional financial arrangements reflects the growing dissatisfaction of the EDEs with the current framework. The global economy is on the cusp of an epochal change moving the fulcrum of economic power from the North Atlantic towards Asia after more than 200 years. This must be recognized and responded to adequately.

Capital Controls or Macroprudential Regulation?
Description: International capital flows can create significant financial instability in emerging economies because of pecuniary externalities associated with exchange rate movements. Does this make it optimal to impose capital controls or should policymakers rely on domestic macroprudential regulation? This paper presents a tractable model to show that it is desirable to employ both types of instruments: Macroprudential regulation reduces overborrowing, while capital controls increase the aggregate net worth of the economy as a whole by also stimulating savings. The two policy measures should be set higher the greater an economy's debt burden and the higher domestic inequality. In our baseline calibration based on the East Asian crisis countries, we find optimal capital controls and macroprudential regulation in the magnitude of 2 percent. In advanced countries where the risk of sharp exchange rate depreciations is more limited, the role for capital controls subsides. However, macroprudential regulation remains essential to mitigate booms and busts in asset prices.

Stress Testing Corporate Balance Sheets in Emerging Economies
Description: In recent years, firms in emerging market countries have increased borrowing, particularly in foreign currency, owing to easy access to global capital markets, prolonged low interest rates and good investment opportunities. This paper discusses the trends in emerging market corporate debt and leverage, and illustrates how those firms are vulnerable to interest rate, exchange rate and earnings shocks. The results of a stress test show that while corporate sector risk remains moderate in most emerging economies, a combination of macroeconomic and financial shocks could significantly erode firms’ ability to service debt and lead to higher debt at risk, especially in countries with high shares of foreign currency debt and low natural hedges.

Big Players Out of Synch: Spillovers Implications of US and Euro Area Shocks
Description: Given the prospects of asynchronous monetary conditions in the United States and the euro area, this paper analyzes spillovers among these two economies, as well as the implications of asynchronicity for spillovers to other advanced economies and emerging markets. Through a structural vector autoregression analysis, country-specific shocks to economic activity and monetary conditions since the early 1990s are identified, and are used to draw implications about spillovers. The empirical findings suggest that real and monetary conditions in the United States and the euro area have oftentimes been asynchronous. The results also point to significant spillovers among them, in particular since early 2014—with spillovers from the euro area to the United States being particularly large. Against the backdrop of asynchronous conditions in these two economies, spillovers from real and money shocks to emerging markets and non-systemic advanced economies could be dampened.
