The Dynamics of Sovereign Debt Crises and Bailouts
Description: Motivated by the recent European debt crisis, this paper investigates the scope for a bailout guarantee in a sovereign debt crisis. Defaults may arise from negative income shocks, government impatience or a "sunspot"-coordinated buyers strike. We introduce a bailout agency, and characterize the minimal actuarially fair intervention that guarantees the no-buyers-strike fundamental equilibrium, relying on the market for residual financing. The intervention makes it cheaper for governments to borrow, inducing them borrow more, leaving default probabilities possibly rather unchanged. The maximal backstop will be pulled precisely when fundamentals worsen.

Cleaning-up Bank Balance Sheets: Economic, Legal, and Supervisory Measures for Italy
Description: To stabilize and bring down nonperforming loans (NPLs) in the Italian banking system, the Italian authorities have been implementing a number of reforms, aimed among others at speeding up insolvency and enforcement proceedings, strengthening bank corporate governance, cleaning up balance sheets, and facilitating bank consolidation. This paper examines the Italian banking system’s NPL problem, which ties up capital, weighing on bank profitability and authorities’ economic reforms. It argues for a comprehensive approach, encompassing economic, supervisory, and legal measures. The authorities’ reforms are important steps toward this end. The paper describes measures that could further support their actions.

Insolvency and Enforcement Reforms in Italy
Description: Italian banks are burdened with high levels of nonperforming loans, the cleanup of which depends in important part on the efficiency of insolvency and enforcement processes. Traditionally, these processes in Italy have taken very long, hampering the timely cleanup of balance sheets. In response, the authorities have legislated a number of measures. This paper explores the recent insolvency and enforcement reforms and the remaining challenges. These reforms introduce important positive changes that are expected to yield full benefits over the medium to long term. The efficacy of the reforms, including to deal with the current stock of high nonperforming loans, can be enhanced by introducing effective out-of-court enforcement mechanisms, supplemented by a more intensive use of informal and hybrid debt-restructuring solutions. Moreover, there is an urgent need to rationalize the system, which over the years has become very complex and intricate.

Fixed Base Year vs. Chain Linking in National Accounts: Experience of Sub-Saharan African Countries
Description: There are two approaches for producing volume estimates of GDP, fixed base year and annual chaining. While most advanced economies have adopted the chain-linked approach in the past twenty years, some African countries are hesitant to do so, in part because of the computation and data requirements, and resource constraints. What difference does this make for the accuracy of the growth rates? From detailed data provided by three Sub-Saharan African countries we run simulations and conclude that the differences of GDP growth using the two approaches are small and do not behave in the consistent way found in advanced countries. We also show that weak deflation techniques and overly aggregated classifications used to derive volume measures can lead to large distortions. We conclude that improved deflation techniques and detailed classification should be addressed before adopting chain linking.

Inflation, Financial Developments, and Wealth Distribution
Description: We find that from 1995 to 2002 in China, the dispersion of wealth decreased, the moneywealth ratio increased for all wealth levels and the aggregate money-output ratio increased. We develop a two-asset dynamic general equilibrium model in which households face a portfolio adjustment cost and a borrowing constraint. We find that financial development lowers the dispersion of wealth by reducing the precautionary motive of households. In addition, tight monetary policies increase the value of money and thus increase the moneywealth ratio for all wealth levels and the aggregate money-output ratio.

An Analysis of OPEC’s Strategic Actions, US Shale Growth and the 2014 Oil Price Crash
Description: In November 2014, OPEC announced a new strategy geared towards improving its market share. Oil-market analysts interpreted this as an attempt to squeeze higher-cost producers including US shale oil out of the market. Over the next year, crude oil prices crashed, with large repercussions for the global economy. We present a simple equilibrium model that explains the fundamental market factors that can rationalize such a "regime switch" by OPEC. These include: (i) the growth of US shale oil production; (ii) the slowdown of global oil demand; (iii) reduced cohesiveness of the OPEC cartel; (iv) production ramp-ups in other non-OPEC countries. We show that these qualitative predictions are broadly consistent with oil market developments during 2014-15. The model is calibrated to oil market data; it predicts accommodation up to 2014 and a market-share strategy thereafter, and explains large oil-price swings as well as realistically high levels of OPEC output.

A Network Model of Multilaterally Equilibrium Exchange Rates
Description: This paper proposes a network model of multilaterally equilibrium exchange rates. The model introduces a topological component into the exchange rate analysis, consistently taking into account simultaneous higher-order interactions among all currencies. The paper defines the currency demand indicator. On its base, it derives a multilateral exchange rate network, finds its dynamically stationary position, and identifies the multilaterally equilibrium levels of bilateral exchanges rates. Potentially, the model can be developed further to calculate the deviations of the observed bilateral exchange rates from their multilaterally equilibrium levels, which can be interpreted as their over- or undervaluation. For illustration, the model is applied to daily 1995-2016 exchange rates among 130 currencies sourced from the Thomson Reuters Datastream.

Outside the Band: Depreciation and Inflation Dynamics in Chile
Description: This paper examines inflation dynamics in Chile during the last peso depreciation episode 2013-15. The evidence is for substantial pass-through effects to inflation, given the large and persistent depreciation movement. Widespread indexation practices in non-traded goods markets are found to amplify the inflation response to the depreciation, while the role of wage indexation is less relevant to the inflation dynamics. Overall, inflation would have remained within the central bank’s target band absent the peso depreciation. The analysis also shows that tightening monetary policy in response to a depreciation shock can be costly in terms of output: the response of activity to rates is found to be strong, while the transmission from activity to inflation is found to be weak. Simulations under uncertainty about the extent of the pass-through also suggest that monetary policy can play a countercyclical role in the face of depreciation shocks at a moderate inflationary cost, as long as inflation expectations remain anchored.

A National Wealth Approach to Banking Crises and Financial Stability
Description: The paper explores a different, supplementary way to assess and manage a particular type of banking crises, those arising from a rise of nonperforming loans to the corporate sector. It relies on a “national wealth approach,” focusing on the distribution of net wealth among economic sectors and its interaction with developments in the banking system. It identifies avenues for policy response optimization, based on an integrated macrofinancial analytical framework, both for the prevention and the resolution of these types of economic events.

What is Keeping U.S. Core Inflation Low: Insights from a Bottom-Up Approach
Description: Over the past two decades, U.S. core PCE goods and services inflation have evolved differently. Against the backdrop of global concerns of low inflation, we use this trend as motivation to develop a bottom-up model of U.S. inflation. We find that domestic forces play a larger role relative to foreign factors in influencing core services inflation, while foreign factors predominantly drive core goods price changes. When comparing forecasting performance, we find that both the aggregate Phillips curve and the bottom up approach give low root mean square errors. The latter, however, is more informative in tracing the effects of shocks and understanding the exact channels through which they affect aggregate inflation. Using scenario analysis—and given a relatively low sensitivity of core inflation to changes in slack, both at the aggregate Phillips curve and sub-components levels—we find that global pressures will likely keep core PCE inflation below 2 percent for the foreseeable future unless the dollar starts to depreciate markedly and the unemployment rate goes well below the natural rate. These results support the accommodative stance of monetary policy pursued thus far and, going forward, underscore the need for proceeding cautiously and very gradually in raising the federal funds rate.
