This paper analyzes the evolution of the degree of global cyclical interdependence over the period 1960-2005. We categorize the 106 countries in our sample into three groups: industrial countries, emerging markets, and other developing economies. Using a dynamic factor model, we then decompose...

Oracles are software components that enable data exchange between siloed blockchains and external environments, enhancing smart contract capabilities and platform interoperability. Oracles play key roles in decentralized finance and blockchain applications in centralized finance. We find that...

This paper analyzes the evolution of inequality in Poland during the economic transition that began in 1989-1990. Using microdata from the Household Budget Surveys, we find that, after a brief spike in 1989, income and consumption inequality actually declined to below pretransition levels during...

The influential work of Ramey and Ramey (1995) highlighted an empirical relationship that has now come to be regarded as conventional wisdom—that output volatility and growth are negatively correlated. We reexamine this relationship in the context of globalization—a term typically used to...

In this paper, we develop an aggregation procedure using time-varying weights for constructing the common component of international economic fluctuations. The methodology for deriving time-varying weights is based on some stylized features of the data documented in the paper. The model allows...

This paper analyzes the evolution of inequality in Poland during the economic transition that began in 1989-90. Using micro data from the Household Budget Surveys, we find that, after a brief spike in 1989, income and consumption inequality actually declined to below pre-transition levels during...

Oracles are software components that enable data exchange between siloed blockchains and external environments, enhancing smart contract capabilities and platform interoperability. Integration through oracle networks for blockchain and DeFi platforms allows them to be informationally and...

We develop a general equilibrium model that highlights the trade-offs between physical and digital forms of retail central bank money. The key differences between cash and central bank digital currency (CBDC) include transaction efficiency, possibilities for tax evasion, and, potentially,...

China's remarkable run of persistently high growth in recent decades is all the more stunning in light of the country's low levels of financial and institutional development, state-dominated economy, and nondemocratic government. Notwithstanding the inefficient and risky growth model, the...
