Current Account Balance Estimates for Emerging Market Economies

This paper uses a modified version of the methodology used by the IMFs Consultative Group on Exchange Rate Issues (CGER) to calculate equilibrium current account balances (or ?norms?) for a sample of 33 emerging market economies. We find that the fundamental determinants of the equilibrium current account balances are similar to those identified by the CGER using a sample that also comprises advanced economies. However, the fiscal balance has a considerably stronger impact on current account norms for emerging markets. This paper also offers estimates for the equilibrium current account balances of eleven smaller emerging market economies that are not currently included in the country sample used by the CGER.

Structural Breaks in Fiscal Performance: Did Fiscal Responsibility Laws Have Anything to do with Them?

In recent years, many countries have adopted Fiscal Responsibility Laws to strengthen fiscal institutions and promote fiscal discipline in a credible, predictable and transparent manner. Still, results on the effectiveness of these laws remain tentative. In this paper, we test empirically whether fiscal performance, measured as the level of primary fiscal balances and their volatility, indeed improved after the implementation of Fiscal Responsibility Laws in a sample of Latin American and advanced economies. We show that traditional econometric approaches, which rely on the use of dummies in time series or panel regressions, yield biased estimates. In contrast, our empirical strategy recognizes that, a priori, the timing of the effect of these laws on fiscal performance is unknown, while controlling for the impact of the business and commodity cycles on fiscal outcomes. Overall, we find limited empirical evidence in support of the view that Fiscal Responsibility Laws have had a distinguishable effect on fiscal performance. However, Fiscal Responsibility Laws could still have other positive effects on the conduct of fiscal policy not analyzed here, for instance, through enhanced transparency and guidance in the budget process and lower risk premia.

The Chilean Output Gap

This paper estimates the potential output (and the output gap) in Chile using several different methodologies. After a structural brake in 1998, the average growth rate of potential output in Chile declined from over 7 percent to 3-4 percent in the aggregate economy, but to less than 2 percent in the natural resource sector. The contributions to aggregate potential output growth of the natural resource sector and the non-natural resource sector are estimated, finding that the contribution to growth of the natural resource sector is non-linear-increasing during the 1990s, declining during the 2000s, and turning negative in the mid-2000s-despite the monotonic decrease in the share of natural resource output in aggregate output.

Measuring the Informal Economy in the Caucasus and Central Asia

This study estimates the size of the informal economy, and the relative contribution of each underlying factor, for the Caucasus and Central Asia countries in 2008. Using a Multiple Indicator-Multiple Cause model, we find that a burdensome tax system, rigid labor market, low institutional quality, and excessive regulation in financial and products markets are determinant factors in explaining the size of the informal economy, which ranges from 26 percent of GDP in Kyrgyz Republic to around 35 percent of GDP in Armenia. Furthermore, the results show that higher levels of informality increase the levels of self employment and the percentage of currency held outside the banking system.

Shadow Economies Around the World: What Did We Learn Over the Last 20 Years?

We undertake an extended discussion of the latest developments about the existing and new estimation methods of the shadow economy. New results on the shadow economy for 158 countries all over the world are presented over 1991 to 2015. Strengths and weaknesses of these methods are assessed and a critical comparison and evaluation of the methods is carried out. The average size of the shadow economy of the 158 countries over 1991 to 2015 is 31.9 percent. The largest ones are Zimbabwe with 60.6 percent, and Bolivia with 62.3 percent of GDP. The lowest ones are Austria with 8.9 percent, and Switzerland with 7.2 percent. The new methods, especially the new macro method, Currency Demand Approach (CDA) and Multiple Indicators Multiple Causes (MIMIC) in a structured hybrid-model based estimation procedure, are promising approaches from an econometric standpoint, alongside some new micro estimates. These estimations come quite close to others used by statistical offices or based on surveys.

Electoral Budget Cycles: The case of the Argentine Provinces

This paper presents subnational evidence of electoraly-motivated changes in the level of public expenditures, budgetary deficits and composition of public expenditures in Argentina. The empirical study is made using a dynamic panel data analysis (GMM) for 22 provinces during period 1985-2001. We find evidence of political cycles in policies around the election date. Results shows that deficits and public expenditures increase in election years. Evidence also suggest that expenditures shift toward more visible public investment and away from current consumption goods.

Measures of fiscal risk in oil-exporting countries

The recent relatively high levels of global oil prices have led to a significant improvement in the public finances of several oil-exporting countries. However, despite the increase in fiscal buffers, medium-term risks remain high. Fiscal vulnerabilities have increased as a consequence of the substantial spending packages that have been implemented in recent years. This has raised break-even prices – that is, the price levels that ensure that fiscal accounts are in balance at a given level of spending – in these countries. This study analyses such risks and develops measures of fiscal risk stemming from oil price fluctuations. An empirical application to oil-exporting countries from the Middle East and North Africa region is included. Additionally, it is worth noting that countries with large net assets and proven oil reserves are much less vulnerable to fiscal risk than is indicated by standard measures based on break-even prices.

Measures of Fiscal Risk in Hydrocarbon-Exporting Countries
