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.

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.

Why Do Bank-Dependent Firms Bear Interest-Rate Risk?
Description: I document that floating-rate loans from banks (particularly important for bank-dependent firms) drive most variation in firms' exposure to interest rates. I argue that banks lend to firms at floating rates because they themselves have floating-rate liabilities, supporting this with three key findings. Banks with more floating-rate liabilities, first, make more floating-rate loans, second, hold more floating-rate securities, and third, quote lower prices for floating-rate loans. My results establish an important link between intermediaries' funding structure and the types of contracts used by non-financial firms. They also highlight a role for banks in the balance-sheet channel of monetary policy.

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.

Strategic Corporate Layoffs
Description: Firms in the S&P 500 often announce layoffs within days of one another, despite the fact that the average S&P 500 constituent announces layoffs once every 5 years. By contrast, similarsized privately-held firms do not behave in this way. This paper provides empirical evidence that such clustering behavior is largely due to CEOs managing their reputation in financial markets. To interpret these results we develop a theoretical framework in which managers delay layoffs during good economic states to avoid damaging the markets perception of their ability. The model predicts clustering in the timing of layoff announcements, and illustrates a mechanism through which the cyclicality of firms layoff policies is amplified. Our findings suggest that reputation management is an important driver of layoff policies both at daily frequencies and over the business cycle, and can have significant macroeconomic consequences.

Dynamic Fuel Price Pass-Through: Evidence from a New Global Retail Fuel Price Database
Description: This paper assesses the dynamic pass-through of crude oil price shocks to retail fuel prices using a novel database on monthly retail fuel prices for 162 countries. The impulse response functions suggest that on average, a one cent increase in crude oil prices per liter translates into a 1.2 cent increase in the retail gasoline price at peak level six months after the shock. However, the estimates vary significantly across country groups, ranging from about 0.5 cent in MENA countries to two cents in advanced economies. The results also show that positive oil price shocks have a larger impact than negative price shocks on the retail gasoline price. Finally, the paper underscores the importance of the new dataset in refining estimates of the fiscal cost of incomplete pass-through.
