International Sovereign Bonds by Emerging Markets and Developing Economies: Drivers of Issuance and Spreads
Description: What determines the ability of low-income developing countries to issue bonds in international capital and what explains the spreads on these bonds? This paper examines these questions using a dataset that includes emerging markets and developing economies (EMDEs) that issued sovereign bonds at least once during the period 1995-2013 as well as those that did not. We find that an EMDE is more likely to issue a bond when, in comparison with non-issuing peers, it is larger in economic size, has higher per capita GDP, and has stronger macroeconomic fundamentals and government. Spreads on sovereign bonds are lower for countries with strong external and fiscal positions, as well as robust economic growth and government effectiveness. With regard to global factors, the results show that sovereign bond spreads are reduced in periods of lower market volatility.

Financial Distortions in China: A General Equilibrium Approach
Description: Widespread implicit guarantees and interest ceilings were major distortions in China’s financial system, contributing to a misallocation of resources. We analyze the impact of removing such frictions in a general equilibrium setting. The results show that comprehensive reforms generate better outcomes than partial ones: removing the deposit rate ceiling alone increases output, but the efficiency of capital allocation does not improve. Removing implicit guarantees improves output through lower cost of capital for private companies and better resource allocation.

A Macro-Model Approach to Monetary Policy Analysis and Forecasting for Vietnam
Description: The paper develops a small New-Keynesian FPAS model for Vietnam. The model closely matches actual data from 2000-2014. We derive an optimal monetary policy rule that minimizes variability of output, inflation, and the exchange rate. Compared to the baseline model, the optimal rule places a larger weight on output stabilization as the intermediate target to achieve inflation stability, while allowing greater exchange rate flexibility. We analyze the dynamics of key macro variables under various shocks including external and domestic demand shocks and a lift-off of U.S. interest rates. We find that the optimal monetary policy rule delivers greater macroeconomic stability for Vietnam under the shock scenarios.

Some Misconceptions about Public Investment Efficiency and Growth
Description: We reconsider the macroeconomic implications of public investment efficiency, defined as the ratio between the actual increment to public capital and the amount spent. We show that, in a simple and standard model, increases in public investment spending in inefficient countries do not have a lower impact on growth than in efficient countries, a result confirmed in a simple cross-country regression. This apparently counter-intuitive result, which contrasts with Pritchett (2000) and recent policy analyses, follows directly from the standard assumption that the marginal product of public capital declines with the capital/output ratio. The implication is that efficiency and scarcity of public capital are likely to be inversely related across countries. It follows that both efficiency and the rate of return need to be considered together in assessing the impact of increases in investment, and blanket recommendations against increased public investment spending in inefficient countries need to be reconsidered. Changes in efficiency, in contrast, have direct and potentially powerful impacts on growth: “investing in investing” through structural reforms that increase efficiency, for example, can have very high rates of return.

March Madness in Wall Street: (What) Does the Market Learn from Stress Tests?
Description: Annual stress tests have become a regular part of the supervisors’ toolkit following the global financial crisis. We investigate their capital market implications in the United States by looking at price and trade reactions, information asymmetry and uncertainty indicators, and bank activities. The evidence we present supports the notion that there is important new information in stress tests, especially at times of financial distress. Moreover, public disclosure seems to help reduce informational asymmetries. Importantly, public disclosure of stress test results (and methodology) does not seem to have reduced private incentives to generate information or to have led to distorted incentives.

Monetary Policy in a Developing Country: Loan Applications and Real Effects
Description: The transmission of monetary policy to credit aggregates and the real economy can be impaired by weaknesses in the contracting environment, shallow financial markets, and a concentrated banking system. We empirically assess the bank lending channel in Uganda during 2010–2014 using a supervisory dataset of loan applications and granted loans. Our analysis focuses on a short period during which the policy rate rose by 1,000 basis points and then came down by 1,200 basis points. We find that an increase in interest rates reduces the supply of bank credit both on the extensive and intensive margins, and there is significant pass-through to retail lending rates. We document a strong bank balance sheet channel, as the lending behavior of banks with high capital and liquidity is different from that of banks with low capital and liquidity. Finally, we show the impact of monetary policy on real activity across districts depends on banking sector conditions. Overall, our results indicate significant real effects of the bank lending channel in developing countries.

How External Factors Affect Domestic Economy: Nowcasting an Emerging Market
Description: External headwinds, together with domestic vulnerabilities, have loomed over the prospects of emerging markets in recent years. We propose an empirical toolbox to quantify the impact of external macro-financial shocks on domestic economies in parsimonious way. Our model is a Bayesian VAR consisting of two blocks representing home and foreign factors, which is particularly useful for small open economies. By exploiting the mixed-frequency nature of the model, we show how the toolbox can be used for “nowcasting” the output growth. The conditional forecast results illustrate that regular updates of external information, as well as domestic leading indicators, would significantly enhance the accuracy of forecasts. Moreover, the analysis of variance decompositions shows that external shocks are important drivers of the domestic business cycle.

Exiting From Fragility in sub-Saharan Africa: The Role of Fiscal Policies and Fiscal Institutions
Description: This paper studies the role of fiscal policies and institutions in building resilience in sub-Saharan African countries during 1990-2013, with specific emphasis on a group of twenty-six countries that were deemed fragile in the 1990s. As the drivers of fragility and resilience are closely intertwined, we use GMM estimation as well as a probabilistic framework to address endogeneity and reverse causality. We find that fiscal institutions and fiscal space, namely the capacity to raise tax revenue and contain current spending, as well as lower military spending and, to some extent, higher social expenditure, are significantly and fairly robustly associated with building resilience. Similar conclusions arise from a study of the progression of a group of seven out of the twenty-six sub- Saharan African countries that managed to build resilience after years of civil unrest and/or violent conflict. These findings suggest relatively high returns to focusing on building sound fiscal institutions in fragile states. The international community can help this process through policy advice, technical assistance, and training on tax administration and budget reforms.

Impact of the New Financial Services Law in Bolivia on Financial Stability and Inclusion
Description: This paper examines the impact of the new financial services law in Bolivia—including credit quotas and interest rate caps—on financial stability and inclusion. So far, credit to “targeted” sectors is growing as intended by the law but the increase in the average loan size of microfinance institutions and the declining number of borrowers point to potentially adverse effects of the interest rate caps on financial inclusion. Looking ahead, while the new law contains many good provisions, international experience suggests that promoting financial access through credit quota and interet rate caps is very challenging. Indeed, trying to meet the 2018 credit target for the productive sectors and social housing could imply the build up of significant financial stability risks. These will need careful monitoring and possible modifications to the credit quotas and interest rate caps.

Explaining Inequality and Poverty Reduction in Bolivia
Description: We investigate the factors driving Bolivia’s success in reducing inequality and poverty during the last 15 years. Our evidence suggests that the reduction was driven mainly by labor income growth at the bottom end of the income distribution. Increases in non-labor income (rents, transfers, remittances) also played a role, but a smaller one, although the introduction of Renta Dignidad has made a big difference for the elderly poor. Labor income increases were concentrated in the informal, low-skilled service and manufacturing sectors. As the gains from the commodity boom go into reverse, and the fiscal envelope becomes much tighter, it will be essential that labor and social policies are well designed and targeted to preserve the poverty and inequality reduction of the last 15 years.
