Inequality, Leverage and Crises: The Case of Endogenous Default
Description: The paper studies how high household leverage and crises can arise as a result of changes in the income distribution. Empirically, the periods 1920-1929 and 1983-2008 both exhibited a large increase in the income share of high-income households, a large increase in debt leverage of the remainder, and an eventual financial and real crisis. The paper presents a theoretical model where higher leverage and crises arise endogenously in response to a growing income share of high-income households. The model matches the profiles of the income distribution, the debt-to-income ratio and crisis risk for the three decades prior to the Great Recession.

The Redistributive Effects of Financial Deregulation
Description: Financial regulation is often framed as a question of economic efficiency. This paper, by contrast, puts the distributive implications of financial regulation center stage. We develop a model in which the financial sector benefits from risk-taking by earning greater expected returns. However, risktaking also increases the incidence of large losses that lead to credit crunches and impose negative externalities on the real economy. We describe a Pareto frontier along which different levels of risktaking map into different levels of welfare for the two parties. A regulator has to trade off efficiency in the financial sector, which is aided by deregulation, against efficiency in the real economy, which is aided by tighter regulation and a more stable supply of credit. We also show that financial innovation, asymmetric compensation schemes, concentration in the banking system, and bailout expectations enable or encourage greater risk-taking and allocate greater surplus to the financial sector at the expense of the rest of the economy.

Credit Constraints, Political Instability, and Capital Accumulation
Description: We investigate the complex interactions between credit constraints, political instability, and capital accumulation using a novel approach based on Kiyotaki and Moore’s (1997) theoretical framework. Drawing on a unique firm-level data set from Middle-East and North Africa (MENA), empirical findings point to a large and significant effect of credit conditions on capital accumulation and suggest that continued political unrest worsens credit constraints. The results support the view that financial development measured by a relaxing of financial constraints is key to macroeconomic development.

Labor Force Participation and Monetary Policy in the Wake of the Great Recession
Description: In this paper, we provide compelling evidence that cyclical factors account for the bulk of the post-2007 decline in the U.S. labor force participation rate. We then proceed to formulate a stylized New Keynesian model in which labor force participation is essentially acyclical during “normal times” (that is, in response to small or transitory shocks) but drops markedly in the wake of a large and persistent aggregate demand shock. Finally, we show that these considerations can have potentially crucial implications for the design of monetary policy, especially under circumstances in which adjustments to the short-term interest rate are constrained by the zero lower bound.

Understanding Countries’ Tax Effort
Description: This paper presents a model to determine the tax effort and tax capacity of 113 countries and the main variables on which they depend. The results and the model allow a clear determination of which countries are near their tax capacity and which are some way from it, and therefore, could increase their tax revenue. This paper also determines central factors on which tax capacity depends: the level of development, trade, education, inflation, income distribution, corruption, and the ease of tax collection.

Local Government Financing Platforms in China: A Fortune or Misfortune?
Description: China’s rapid credit expansion in 2009–10 brought local government financing platforms (LGFPs) into the spotlight. This paper discusses their function, reasons behind their recent expansion, and risks they are posing to the financial sector, local governments, and sovereign balance sheet. This paper argues that LGFPs were a fortune for China in the past, but would turn out to be a misfortune if the causes of the rapid expansion of LGFPs are not addressed promptly. In this context, the paper proposes ways to avoid misfortune by: acknowledging and addressing the revenue and expenditure mismatches at the local government level; establishing a comprehensive framework to regulate and supervise local government budgets; ensuring the sustainability of the financial resources obtained from the sale of land use rights; and developing local government bond markets and promoting financial reforms.

Baltic and Icelandic Experiences of Capital Flows and Capital Flow Measures
Description: The aim of this empirical study is to describe and provide analysis on the experience of managing capital flows in Iceland and the Baltic countries. During the build-up of the crisis, there were shortcomings in macroeconomic policies and in the policy mix, as well as in financial supervision in the countries covered. While the use of traditional macroeconomic and structural policies was far from exhausted, recognizing that there are no substitutes for sound macroeconomic policies, with an IMF framework on capital flows in place prior to the crisis, it might have been easier for the IMF and national policymakers to identify accelerating problems at an early stage and address them with targeted measures.

Aggregate Uncertainty and the Supply of Credit
Description: Recent studies show that uncertainty shocks have quantitatively important effects on the real economy. This paper examines one particular channel at work: the supply of credit. It presents a model in which a bank, even if managed by risk-neutral shareholders and subject to limited liability, can exhibit self-insurance, and thus loan supply contracts when uncertainty increases. This prediction is tested with the universe of U.S. commercial banks over the period 1984-2010. Identification of credit supply is achieved by looking at the differential response of banks according to their level of capitalization. Consistent with the theoretical predictions, increases in uncertainty reduce the supply of credit, more so for banks with lower levels of capitalization. These results are weaker for large banks, and are robust to controlling for the lending and capital channels of monetary policy, to different measures of uncertainty, and to breaking the dataset in subsamples. Quantitatively, uncertainty shocks are almost as important as monetary policy ones with regards to the effects on the supply of credit.

Sector-Level Productivity, Structural Change, and Rebalancing in China
Description: This paper studies structural changes underlying China's remarkable and unprecedented growth in recent years. While patterns of structural transformation across China's provinces are broadly in line with international experience, one important difference is in labor productivity differentials between services and the rest of the economy. Specifically, the gap between labor productivity in the rest of the economy and services has widened across China's provinces as they have moved from low to middle income, which is contrary to the trend observed in cross-country experience. Evidence from a panel of China's provinces suggests that credit and labor market frictions have inhibited labor productivity growth in services relatively more than in the rest of the economy. Reducing these frictions is essential for achieving the next stage of China's development, one in which the service sector will need to play a more prominent role as an engine of growth. The evidence also suggests that improving labor productivity in services will lift the consumption share of GDP, thereby advancing the needed rebalancing of domestic demand in China.

Money Targeting in a Modern Forecasting and Policy Analysis System: an Application to Kenya
Description: We extend the framework in Andrle and others (2013) to incorporate an explicit role for money targets and target misses in the analysis of monetary policy in low-income countries (LICs), with an application to Kenya. We provide a general specification that can nest various types of money targeting (ranging from targets based on optimal money demand forecasts to those derived from simple money growth rules), interest-rate based frameworks, and intermediate cases. Our framework acknowledges that ex-post adherence to targets is in itself an objective of policy in LICs; here we provide a novel interpretation of target misses in terms of structural shocks (aggregate demand, policy, shocks to money demand, etc). In the case of Kenya, we find that: (i) the setting of money targets is consistent with money demand forecasting, (ii) targets have not played a systematic role in monetary policy, and (iii) target misses mainly reflect shocks to money demand. Simulations of the model under alternative policy specifications show that the stronger the ex-post target adherence, the greater the macroeconomic volatility. Our findings highlight the benefits of a model-based approach to monetary policy analysis in LICs, including in countries with money-targeting frameworks.
