Financial and Business Cycles in Brazil
Description: This paper explores the nexus between the financial cycle and business cycle in Brazil. Cycles are estimated using a variety of commonly-used statistical methods and with a small, semistructural model of the Brazilian economy. An advantage of using the model-based approach is that financial and business cycles can be jointly estimated, allowing information from all key economic relationships to be used in a consistent way. The results show that Brazil is now in the downturn phase of the financial cycle. Moreover, the results underscore the importance of macro-financial linkages and highlight risks to the recovery going forward.

The Relative Effectiveness of Spot and Derivatives Based Intervention: The Case of Brazil
Description: This paper studies the relative effectiveness of foreign exchange intervention in spot and derivatives markets. We make use of Brazilian data where spot and non-deliverable futures based intervention have been used in tandem for more than a decade. The analysis finds evidence in favor of a significant link between both modes of intervention and the first two moments of the real/dollar exchange rate. As predicted by theory for the case of negligible convertibility risk, the impact of spot market intervention in our baseline sample is strikingly similar to that achieved through futures based intervention worth an equivalent amount in notional principal.

Price and Wage Flexibility in Hong Kong SAR
Description: The paper assesses the price and wage flexibility in Hong Kong SAR. At the aggregate level, it compares Hong Kong SAR with the United States, the United Kingdom and Singapore by examining the three commonly used macroeconomic relationships among inflation, unemployment, wage growth, and output fluctuations. At the industry level, the paper compares the distributions of labor earnings and price growth in Hong Kong SAR and the United States. It further estimates a model of wage formation under downward nominal wage rigidity to compare the extent of wage rigidity in Hong Kong SAR and the United States. Overall, the comparisons show that broadly speaking, price and wage adjustments are more flexible in Hong Kong SAR than other economies.

Optimal Tax Administration
Description: This paper sets out a framework for analyzing optimal interventions by a tax administration, one that parallels and can be closely integrated with established frameworks for thinking about optimal tax policy. Its key contribution is the development of a summary measure of the impact of administrative interventions—the “enforcement elasticity of tax revenue”—that is a sufficient statistic for the behavioral response to such interventions, much as the elasticity of taxable income serves as a sufficient statistic for the response to tax rates. Amongst the applications are characterizations of the optimal balance between policy and administrative measures, and of the optimal compliance gap.

Indian Financial Sector: Structure, Trends and Turns
Description: This paper traces the story of Indian financial sector over the period 1950–2015. In identifying the trends and turns of Indian financial sector, the paper adopts a three period classification viz., (a) the 1950s and 1960s, which exhibited some elements of instability associated with laissez faire but underdeveloped banking; (b) the 1970s and 1980s that experienced the process of financial development across the country under government auspices, accompanied by a degree of financial repression; and (c) the period since the 1990s till date, that has been characterized by gradual and calibrated financial deepening and liberalization. Focusing more the third period, the paper argues that as a consequence of successive reforms over the past 25 years, there has been significant progress in making interest and exchange rates largely market determined, though the exchange rate regime remains one of managed float, and some interest rates remain administered. Considerable competition has been introduced in the banking sector through new private sector banks, but public sector banks continue have a dominant share in the market. Contractual savings systems have been improved, but pension funds in India are still in their infancy. Similarly, despite the introduction of new private sector insurance companies coverage of insurance can expand much further, which would also provide greater depth to the financial markets. The extent of development along all the segments of the financial market has not been uniform. While the equity market is quite developed, activities in the private debt market are predominantly confined to private placement form and continue to be limited to the bluechip companies. Going forward, the future areas for development in the Indian financial sector would include further reduction of public ownership in banks and insurance companies, expansion of the contractual savings system through more rapid expansion of the insurance and pension systems, greater spread of mutual funds, and development of institutional investors. It is only then that both the equity and debt markets will display greater breadth as well as depth, along with greater domestic liquidity. At the same time, while reforming the financial sector, the Indian authorities had to constantly keep the issues of equity and efficiency in mind.

Fiscal Rules to Tame the Political Budget Cycle: Evidence from Italian Municipalities
Description: The paper provides evidence that fiscal rules can limit the political budget cycle. It focuses on the application of the Italian fiscal rule at the sub-national level over the period 2004-2006 and shows that: 1) municipalities are subject to political budget cycles in capital spending; 2) the Italian subnational fiscal rule introduced in 1999 has been enforced by the central government; 3) municipalities subject to the fiscal rule show more limited political budget cycles than municipalities not subject to the rule. In order to identify the effect, we rely on the fact that the domestic fiscal rule does not apply to municipalities below 5,000 inhabitants. We find that the political budget cycle increases real capital spending by about 35 percent on average in the years prior to municipal elections and that the sub-national fiscal rule reduces these figures by about two thirds.

On the Determinants of Fiscal Non-Compliance: An Empirical Analysis of Spain’s Regions
Description: This paper proposes an empirical framework that distinguishes voluntary from involuntary compliance with fiscal deficit targets on the basis of economic, institutional, and political factors. The framework is applied to Spain’s Autonomous Communities (regions) over the period 2002-2015. Fiscal noncompliance among Spain’s regions has shown to be persistent. It increases with the size of growth forecast errors and the extent to which fiscal targets are tightened, factors not fully under the control of regional governments. Non-compliance also tends to increase during election years, when vertical fiscal imbalances accentuate, and market financing costs subside. Strong fiscal rules have not shown any significant impact in containing fiscal non-compliance. Reducing fiscal non-compliance in multilevel governance systems such as the one in Spain requires a comprehensive assessment of intergovernmental fiscal arrangements that looks beyond rules-based frameworks by ensuring enforcement procedures are politically credible.

How Buoyant is the Tax System? New Evidence from a Large Heterogeneous Panel
Description: In this paper we provide short- and long-run tax buoyancy estimates for 107 countries (distributed between advanced, emerging and low-income) for the period 1980–2014. By means of Fully-Modified OLS and (Pooled) Mean Group estimators, we find that: i) for advanced economies both long-run and short-run buoyancies are not different from one; ii) long run tax buoyancy exceeds one in the case of CIT for advanced economies, PIT and SSC in emerging markets, and TGS for low income countries, iii) in advanced countries (emerging market economies) CIT (CIT and TGS) buoyancy is larger during contractions than during times of economic expansions; iv) both trade openness and human capital increase buoyancy while inflation and output volatility decrease it.

Korea’s Challenges Ahead—Lessons from Japan’s Experience
Description: This paper draws out the parallels between Korea and Japan in terms of demographics, potential growth, balance sheets, asset prices and inflation. Korea’s demographic trends seem to track Japan’s with a lag of about 20 years. Low productivity in the service sector and labor market duality are common to both countries and need to be addressed with structural reforms. While Korea’s corporate balance sheets are stronger than Japan’s in the early 1990s, Korea needs to progress with the restructuring of nonviable firms to avoid the adverse consequences of delayed balance-sheet repair that Japan experienced. Given its strong fiscal balance sheet position, Korea can afford using fiscal policy actively to incentivize corporate restructuring and structural reforms and cushion their possible short-term adverse impact. Korea can prevent bubbles in asset prices that were at the origin of Japan’s initial crisis with the continued use of macroprudential policies. Although Korea does not appear to be headed toward deflation, new econometric analysis presented in the paper suggests that aging will exert a downward drag on its inflation going forward.

Benefits of Global and Regional Financial Integration in Latin America
Description: The timing is ripe to pursue greater regional financial integration in Latin America given the withdrawal of some global banks from the region and the weakening of growth prospects. Important initiatives are ongoing to foster financial integration. Failure to capitalize on this would represent a significant missed opportunity. This paper examines the scope for further global and regional financial integration in Latin America, based on economic fundamentals and comparisons to other emerging regions, and quantifies the potential macroeconomic gains that such integration could bring. The analysis suggests that closing the financial integration gap could boost GDP growth be ¼ - ¾ percentage point in these countries, on average.
