Inflation Dynamics and Monetary Policy in Bolivia
Description: This paper explores inflation dynamics and monetary policy in Bolivia. Bolivia’s monetary policy framework has been effective in stabilizing inflation in recent times. This has been a challenging task given high price volatility of key consumer goods subject to recurrent supply shocks, especially food items. Empirical testing indicates that the monetary policy framework has contributed to the stabilization of inflation, with effective transmission through the bank lending channel, while the defacto dollar peg has also played a role. Looking ahead, the current framework will be tested by the new commodity price normal and a potentially permanent adjustment in relative prices. Against this background, consideration could be given to a more flexible exchange rate policy arrangement, with short term interest rates as the main policy instrument.

Crowding-Out or Crowding-In? Public and Private Investment in India
Description: This paper contributes to the debate on the relationship between public-capital accumulation and private investment in India along the following dimensions. First, acknowledging major structural changes that the Indian economy has undergone in the past three decades, we study whether public investment in recent years has become more or less complementary to private investment in comparison to the period before 1980. Second, we construct a novel data-set of quarterly aggregate public and private investment in India over the period 1996Q2-2015Q1 using investment-project data from the CapEx-CMIE database. Third, embedding a theory-driven long-run relationship on the model, we estimate a range of Structural Vector Error Correction Models (SVECMs) to re-examine the public and private investment relationship in India. Identification is achieved by decomposing shocks into those with transitory and permanent effects. Our results suggest that while public-capital accumulation crowds out private investment in India over 1950-2012, the opposite is true when we restrict the sample post 1980 or conduct a quarterly analysis since 1996Q2. This change can most likely be attributed to the policy reforms which started during early 1980s and gained momentum after the 1991 crises.

Emerging Market Portfolio Flows: The Role of Benchmark-Driven Investors
Description: Portfolio flows to emerging markets (EMs) tend to be correlated. A possible explanation is the role global benchmarks play in allocating capital internationally, the so-called “benchmark effect.” This paper finds that benchmark-driven investors indeed play a large role in a key segment of the market—the EM local currency government bond market—, accounting for more than one third of total foreign holdings as of end-2014. We find that the prominence of these investors declined somewhat after the May 2013 taper tantrum, but remain high. This distinction is important in understanding the drivers of EM capital flows and their sensitivity to different types of shocks. In particular, a high share of benchmark-driven investors may result in capital flows that are more sensitive to global shocks and less sensitive to country factors.

Fiscal Consolidation During Times of High Unemployment: The Role of Productivity Gains and Wage Restraint
Description: This paper studies the Swedish fiscal consolidation episode of the 1990s through the lens of a small open economy model with distortionary taxation and unemployment. We argue that the simultaneous reduction in the fiscal deficit and unemployment rate in this episode stems from two factors: (i) high growth rates of total factor productivity (TFP), experienced after the implementation of structural reforms; and (ii) a sustained wage restraint that occurred during the 1990s. The model simulations show that economic growth, accounted for mostly by TFP gains, improved the fiscal balance by 8 percentage points of GDP through an expansion of the tax base and fiscal revenues. Moreover, the combination of stable wages and higher TFP boosted net exports and led to a reduction in the unemployment rate. A counterfactual simulation assuming stagnant TFP shows that fiscal consolidation measures alone would have generated a double-digit unemployment rate without eliminating the fiscal deficit.

The Whole Elephant: A Proposal for Integrating Cash, Accrual, and Sustainability-Gap Accounts
Description: Although the budget deficit is much discussed in political debate and economic research, there is no agreement on how it should be measured. There are at least four options, which can be called the cash deficit, the financial deficit, the full-accrual deficit, and the comprehensive deficit. Each is informative, but each has problems of relevance or reliability. Some are more vulnerable to manipulation involving assets and liabilities that are unrecognized in the underlying accounting, others to manipulation involving the mismeasurement of recognized assets and liabilities. Governments should publish all four in a form that reveals their interrelationships.

Interest Rate Pass-Through in the Dominican Republic
Description: A well-functioning monetary transmission mechanism is critical for monetary policy. As the Dominican Republic recently adopted an inflation targeting regime, it is even more relevant to guarantee that changes in the monetary policy rates are quickly and fully reflected in retail rates, to eventually influence aggregate demand and inflation. This paper estimates the interest rate pass-through of the monetary policy rate to retail rates and explores asymmetries in the adjustment. We find evidence of complete pass-through to retail rates, confirming the effectiveness of the monetary policy transmission mechanism. However, our results also suggest a faster pass-through to lending rates than to deposit rates and asymmetric adjustments of short-term rates, as deposit rates respond faster to policy rate cuts and lending rates respond faster to policy rate hikes. Measures to enhance competition in the financial system could help to achieve a symmetric adjustment of retail rates.

The U.S. Oil Supply Revolution and the Global Economy
Description: This paper investigates the global macroeconomic consequences of falling oil prices due to the oil revolution in the United States, using a Global VAR model estimated for 38 countries/regions over the period 1979Q2 to 2011Q2. Set-identification of the U.S. oil supply shock is achieved through imposing dynamic sign restrictions on the impulse responses of the model. The results show that there are considerable heterogeneities in the responses of different countries to a U.S. supply-driven oil price shock, with real GDP increasing in both advanced and emerging market oil-importing economies, output declining in commodity exporters, inflation falling in most countries, and equity prices rising worldwide. Overall, our results suggest that following the U.S. oil revolution, with oil prices falling by 51 percent in the first year, global growth increases by 0.16 to 0.37 percentage points. This is mainly due to an increase in spending by oil importing countries, which exceeds the decline in expenditure by oil exporters.

Taylor Visits Africa
Description: Many low-income countries do not use interest rates as their main monetary policy instrument. In East Africa, for instance, targeting money aggregates has been pretty much the rule rather than the exception. Nevertheless, these targets are seldom met and often readjusted according to the economic environment. This opens up the possibility that central banks are de facto pursuing a strategy more akin to a Taylor Rule. Estimations of small-scale models for Kenya, Uganda and Tanzania suggest that these self-styled "monetary targeters" are respecting the Taylor Principle, that is are on average increasing nominal interest rates more than proportionally to inflation. Nevertheless, steep deviations from the Taylor Rule have taken place in Kenya and Tanzania. In Uganda, these errors are much smaller, in fact similar in size to Taylor Rule deviations found for Brazil. More surprisingly, they are smaller than South Africa’s, the continent’s sole long-term inflation targeter.

Debt Maturity: Does It Matter for Fiscal Space?
Description: This paper examines how debt maturity affects the debt limit, defined as the maximum amount of debt a government can afford without defaulting. We develop a model where investors are risk neutral, the primary balance is stochastic but exogenous, and default occurs solely due to the government’s inability to pay. We find that debt limit is higher for long-term debt. Underlying this finding is the intrinsic advantage of long-term debt to price in future upside potential in fiscal outcomes in its current price. Such advantage makes long-term debt effectively cheaper than short-term debt at the margin, and leads to a higher debt limit. Simulation results suggest that the effect of debt maturity on debt limit could be substantial—particularly, if fiscal outcomes are subject to large uncertainty.

If the Fed Acts, How Do You React? The Liftoff Effect on Capital Flows
Description: After more than six years of ultra-low interest rates, a Fed liftoff (rate hike) is just a matter of time. This paper goes back to history to understand the spillover effect – or what is termed in the paper as the ‘liftoff’ effect – of the previous five Fed liftoffs on capital flows. Using a dynamic panel framework covering 48 countries (27 advanced economies, 21 emerging markets) over the period 1982-2006, the paper shows that the liftoff effect on capital flows (total private, portfolio) is significantly higher for emerging market economies (EM) than advanced market economies (AM). EM capital flows are hit indiscriminately one quarter before liftoff, suggesting that markets usually price in the liftoff before the actual event. Over time, there is a bit more variation among EM as policy responses/framework can to some extent dampen market reactions. The findings are similar to the unfolding of events during the taper tantrum episode indicating that, even though current circumstances are very different, history could still provide a good guidance.
