This paper proposes a novel shrinkage estimator for high-dimensional covariance matrices by extending the Oracle Approximating Shrinkage (OAS) of Chen et al. (2009) to target the diagonal elements of the sample covariance matrix. We derive the closed-form solution of the shrinkage parameter and...

This paper studies the linkage between structural coherence and economic growth. Structural coherence is defined as the degree that a country's industrial structure optimally reflects its factor endowment fundamentals. The paper found that at least for the overall capital, the shares of capital...

This paper presents a simultaneous assessment of the relationship between economic performance and three groups of economic reforms: domestic finance, trade, and the capital account. Among these, domestic financial reforms, and trade reforms, are robustly associated with economic growth, but...

While India’s growth has been strong in recent decades, its structural transformation remains incomplete. In this paper, we first take stock of India’s growth to date. We find that economic activity has shifted from agriculture to services, but agriculture remains the predominant employer....

We study the effects of services trade reforms in a multi-country multi-sector quantitative trade model with input-output linkages. We find that (i) welfare gains from substantial services trade liberalization are large, around 3 percent on average; (ii) gains are larger by 0.7 percentage points...

To date, an operational measure of systemic risk capturing non-linear tail comovement between system-wide and individual bank returns has not yet been developed. This paper proposes an extension of the so-called CoVaR measure that captures the asymmetric response of the banking system to...

Which structural reforms affect the speed the regional convergence within a country? We found that domestic financial development, trade/current account openness, better institutional infrastructure, and selected labor market reforms facilitate regional convergence. However, these reforms have...

Regional integration of Pacific Island countries (PICs) with Australia, New Zealand, and emerging Asia has increased over the last two decades. PICs have become more exposed to the region’s business cycles, and spillovers from regional economies are more important for PICs than from...

The degree of an economy’s monetization, which has an important implication on economic growth, can be affected by the conduct of monetary policy, financial sector reform, and episodes of financial crises. The paper finds that monetization--measured by the ratio of broad money to nominal...

Consumer price indexes (CPIs) are compiled at the higher (weighted) level using Laspeyres-type arithmetic averages. This paper questions the suitability of such formulas and considers two counterpart alternatives that use geometric averaging, the Geometric Young and the (price-updated) Geometric...
