Systemic Risk from Global Financial Derivatives: A Network Analysis of Contagion and Its Mitigation with Super-Spreader Tax
Description: Financial network analysis is used to provide firm level bottom-up holistic visualizations of interconnections of financial obligations in global OTC derivatives markets. This helps to identify Systemically Important Financial Intermediaries (SIFIs), analyse the nature of contagion propagation, and also monitor and design ways of increasing robustness in the network. Based on 2009 FDIC and individually collected firm level data covering gross notional, gross positive (negative) fair value and the netted derivatives assets and liabilities for 202 financial firms which includes 20 SIFIs, the bilateral flows are empirically calibrated to reflect data-based constraints. This produces a tiered network with a distinct highly clustered central core of 12 SIFIs that account for 78 percent of all bilateral exposures and a large number of financial intermediaries (FIs) on the periphery. The topology of the network results in the “Too- Interconnected-To-Fail” (TITF) phenomenon in that the failure of any member of the central tier will bring down other members with the contagion coming to an abrupt end when the ‘super-spreaders’ have demised. As these SIFIs account for the bulk of capital in the system, ipso facto no bank among the top tier can be allowed to fail, highlighting the untenable implicit socialized guarantees needed for these markets to operate at their current levels. Systemic risk costs of highly connected SIFIs nodes are not priced into their holding of capital or collateral. An eigenvector centrality based ‘super-spreader’ tax has been designed and tested for its capacity to reduce the potential socialized losses from failure of SIFIs.

Taxation and Leverage in International Banking
Description: This paper explores how corporate taxes affect the financial structure of multinational banks. Guided by a simple theory of optimal capital structure it tests (i) whether corporate taxes induce subsidiary banks to raise their debt-asset ratio in light of the traditional debt bias; and (ii) whether international corporate tax differentials vis-a-vis foreign subsidiary banks affect the intra-bank capital structure through international debt shifting. Using a novel subsidiary-level dataset for 558 commercial bank subsidiaries of the 86 largest multinational banks in the world, we find that taxes matter significantly, through both the traditional debt bias channel and the international debt shifting that is due to the international tax differentials. The latter channel is more robust and tends to be quantitatively more important. Our results imply that taxation causes significant international debt spillovers through multinational banks, which has potentially important implications for tax policy.

Nonfinancial Firms in Latin America: A Source of Vulnerability?
Description: We examine corporate sector vulnerabilities in Brazil, Chile, Colombia, Mexico and Peru. First, we identify stylized facts based on corporate financial indicators. Second, we assess vulnerability of individual firms to a sudden stop in financing through a probit model, using a panel of 18 countries in 2000-11. Results suggest that higher leverage and maturity exposures raise a firm’s probability to become exposed to a funding shock, while a larger firm size and buffers reduce it. Further, greater exchange rate flexibility can help mitigate corporate vulnerability. Identification of firms at risk through the model suggests that some vulnerabilities may be building in Latin America led by leverage, currency exposures and moderating buffers. These effects are partially offset, however, by a significant reduction in maturity exposures.

Modeling the Impact of Taxes on Petroleum Exploration and Development
Description: We present a simple model of petroleum exploration and development that can be applied to study the performance of alternative tax systems and identify potential distortions. Although the model is a highly simplified, it incorporates many factors and some of the key tradeoffs that would influence an investor’s investment behavior. The model recognizes the role of enhanced oil recovery and treats the impact of taxation on exploration and development in an integrated manner consistent with an investor’s joint optimization of investments at both stages of the process. The model is simple and user-friendly, which facilitates application to a broad range of problems.

Is China Over-Investing and Does it Matter?
Description: Now close to 50 percent of GDP, this paper assesses the appropriateness of China’s current investment levels. It finds that China’s capital-to-output ratio is within the range of other emerging markets, but its economic growth rates stand out, partly due to a surge in investment over the last decade. Moreover, its investment is significantly higher than suggested by cross-country panel estimation. This deviation has been accumulating over the last decade, and at nearly 10 percent of GDP is now larger and more persistent than experienced by other Asian economies leading up to the Asian crisis. However, because its investment is predominantly financed by domestic savings, a crisis appears unlikely when assessed against dependency on external funding. But this does not mean that the cost is absent. Rather, it is distributed to other sectors of the economy through a hidden transfer of resources, estimated at an average of 4 percent of GDP per year.

The Challenges of Fiscal Consolidation and Debt Reduction in the Caribbean
Description: This paper examines debt dynamics in the Caribbean and discusses policy options for reducing the high debt levels. Based on empirical studies of factors underlying global large debt reduction episodes, important policy lessons are drawn for the Caribbean. The analysis shows that major debt reductions are associated with strong growth and decisive and lasting fiscal consolidation efforts. Since growth in the current environment is virtually nonexistent, significant fiscal consolidation is inevitable in the region. Better control of the public wage bill, increasing public sector efficiency and tackling transfers are the obvious targets to reduce spending. On the revenue side, there is ample room to reduce tax expenditures, eliminate distortions while broadening the tax base. Fiscal consolidation needs to be complemented by a comprehensive debt reduction strategy including tax policy reforms and structural reforms to boost competiveness.

Effects of Capital Flow Liberalization: What is the Evidence from Recent Experiences of Emerging Market Economies?
Description: This paper analyzes the experiences of emerging market economies (EMEs) that have liberalized capital flows over the past 15 years with respect to macroeconomic performance and risks to financial stability. The results of the panel data regressions indicate that greater openness to capital flows is associated with higher growth, gross capital flows, and equity returns and with lower inflation and bank capital adequacy ratios. The effects vary depending on thresholds. As a potential application of these findings, the paper explores the possible effects of liberalization on China by applying the coefficients of explanatory variables to the corresponding variables of China in 2012–16.

Public Investment in Resource-Abundant Developing Countries
Description: Natural resource revenues provide a valuable source to finance public investment in developing countries, which frequently face borrowing constraints and tax revenue mobilization problems. This paper develops a dynamic stochastic small open economy model to analyze the macroeconomic effects of investing natural resource revenues, making explicit the role of pervasive features in these countries including public investment inefficiency, absorptive capacity constraints, Dutch disease, and financing needs to sustain capital. Revenue exhaustibility raises medium-term issues of how to sustain capital built during a windfall, while revenue volatility raises short-term concerns about macroeconomic instability. Using the model, country applications show how combining public investment with a resource fund---a sustainable investing approach---can help address the macroeconomic problems associated with both exhaustibility and volatility. The applications also demonstrate how the model can be used to determine the appropriate magnitude of the investment scaling-up (accounting for the financing needs to sustain capital) and the adequate size of a stabilization fund (buffer).

Fiscal Rules at a Glance: Country Details from a New Dataset
Description: This paper provides country-specific information on fiscal rules in use in 81 countries from 1985 to end-September 2012. It serves as background material and update of the July 2012 Working Paper “Fiscal Rules in Response to the Crisis—Toward the ‘Next Generation’ Rules: A New Dataset” and is also available in an easy accessible electronic data visualization tool (http://www.imf.org/external/datamapper/FiscalRules/map/map.htm.).The dataset covers four types of rules: budget balance rules, debt rules, expenditure rules, and revenue rules, applying to the central or general government or the public sector. It also presents details on various characteristics of rules, such as their legal basis, coverage, escape clauses, as well as key supporting features such as independent monitoring bodies.

The East African Community: Prospects for Sustained Growth
Description: The East African Community (EAC) has been among the fastest growing regions in sub-Saharan Africa in the past decade or so. Nonetheless, the recent growth path will not be enough to achieve middle-income status and substantial poverty reduction by the end of the decade—the ambition of most countries in the region. This paper builds on methodologies established in the growth literature to identify a group of countries that achieved growth accelerations and sustained growth to use as benchmarks to evaluate the prospects, and potential constraints, for EAC countries to translate their recent growth upturn into sustained high growth. We find that EAC countries compare favorably to the group of sustained growth countries—macroeconomic and government stability, favorable business climate, and strong institutions—but important differences remain. EAC countries have a smaller share of exports, lower degree of financial deepening, lower levels of domestic savings, higher reliance on donor aid, and limited physical infrastructure and human capital. Policy choices to address some of these shortcomings could make a difference in whether the EAC follows the path of sustained growth or follows other countries where growth upturns later fizzled out.
