In a two-country portfolio model with leverage constraints, I focus on private assets in order to understand how their behaviour can justify an expected excess return as well as the flight-to-safety observed in the data. The specific goal is to study how much these phenomena are explained by the...

I develop an open economy portfolio model to study how leveraged investors' wholesale funding affects the international transmission of shocks. Under binding borrowing limits, there is a link between the international investment positions of integrated economies as investors diversify the asset...

This paper develops a macroeconomic framework where the representative bank is owned by inside and outside owners and copes with capital requirements that vary countercyclically. The issuance of outside equity is characterized getting insights from the literature on corporate governance,...

I study the composition of international portfolios under collateral constraints and the implied cross-border transmission of shocks. I develop an international portfolio model with these features, in which leveraged investors seek diversification in both assets and secured liabilities and in...

This paper applies long-memory techniques (both parametric and semi-parametric) to examine whether Brexit has led to any significant changes in the degree of persistence of the FTSE (Financial Times Stock Index) 100 Implied Volatility Index (IVI) and of the British pound's implied volatilities...

This paper examines the degree of persistence in UK inflation by applying long-memory methods to historical data that span the period from 1660 to 2016. Specifically, we use both parametric and non-parametric fractional integration techniques, that are more general than those based on the...
