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...

Tourism was one of the fastest-growing sectors before the COVID-19 pandemic, accounting for about 10 percent of global GDP. But it has also created a number of challenges including environmental degradation, especially in small island countries where the carbon footprint of tourism constitute...

Studying a large number of banks in various countries between 1999 and 2006, we document that foreign banks perform better when from a high income country, when host country competition is limited, and when they are large and rely more on deposits for funding. Foreign banks' performance improves...

This paper studies corporate performance in the aftermath of the global crisis by examining 6,581 manufacturing firms in 48 developed and developing countries in 2010, identifying factors of resilience as well as vulnerability. Based on a cross-sectional analysis, the results show that...

Using a unique representative panel survey of Vietnamese enterprises in 2020, we find that the pandemic and associated government support package had a heterogenous impact across firms. The government support package, particularly tax cuts and deferrals, helped alleviate short term stress, but...

Climate change is an existential threat to the global economy and financial markets. There is a large body of literature documenting potential macroeconomic consequences of climate change, but firm-level empirical research on how climate change affects the performance of firms remains scarce....

Currency option implied volatility predicts more efficiently exchange rate volatility for the Polish zloty relative to the Czech koruna, reflecting differences in the frequency of central bank intervention in the foreign exchange market. A GARCH model shows a positive impact of the introduction...

We show the importance of a dynamic aggregation bias in accounting for the PPP puzzle. We prove that established time-series and panel methods substantially exaggerate the persistence of real exchange rates because of heterogeneity in the dynamics of disaggregated relative prices. When...

Unit value export and import indices compiled from returns to customs authorities are often used as surrogates for price indices in the measurement of inflation transmission, terms of trade (effects), and to deflate import and export value series to derive volume series. Their widespread use is...

The paper examines empirically the question of whether more unequal societies spend more on income redistribution than their more egalitarian counterparts. Theoretical arguments on this issue are inconclusive. The political economy literature suggests that redistributive spending is higher in...
