We propose new methods for estimating the bid-ask spread from observed transaction prices alone. Our methods are based on the empirical characteristic function instead of the sample autocovariance function like the method of Roll (1984). As in Roll (1984), we have a closed form expression for...

We develop and apply a new methodology in order to study the transmission mechanisms of international macroeconomic and financial shocks in the context of emerging markets. We propose a time-varying multi level factor augmented global VAR model which combines aspects of factor analysis and GVAR...

The present paper examines the degree of comovement of gross capital inflows, which is a highly sensitive issue for policy makers. We estimate a dynamic hierarchical factor model that is able to decompose inflows in a sample of 47 economies into (i) a global factor common to all types of flows...

We analyze the interaction between monetary policy in the US and the global economy, using a global vector autoregressive model with time-varying parameters and stochastic volatility (TVP-SV-GVAR). We find that a contractionary US monetary policy shock leads to a persistent fall in international...

This paper integrates innovation input and output effects of R&D subsidies into a modified Crépon–Duguet–Mairesse (CDM) model. Our results largely confirm insights of the input additionality literature, i.e. public subsidies complement private R&D investment. In addition, results point to...

In this paper, we propose a new method to assess the impact of sovereign ratings on sovereign bond yields. We estimate the impulse response of the interest rate, following a change in the rating. Since ratings are ordinal and moreover extremely persistent, it proves difficult to estimate those...

In this paper we measure the systemic risk in a set of large international banks. We first measure the contribution of a financial institution to international systemic risk. Importantly, we show the existence of an asymmetric non-linear contribution of banks to systemic risk depending on...

Since the beginning of the decade, flows to institutional and retail products in the international small cap space have grown at a faster clip than flows to international large caps.The reasons for this are fairly obvious - greater alpha generating opportunities and higher diversification...

This paper studies, within a growth model, some effects of the inequality between the profit and growth rates on the reproduction of economic elites. To this end, it considers as functions of the capital/income ratio the relations between, on the one hand, the rate of economic growth and, on the...

In today's turbulent marketplace with unprecedented portfolio turnover, transition activity and drawdowns, one must identify and eliminate all sources of Sharpe ratio erosion. In this environment, trading costs and risks are significant contributors to this performance drag and avoiding them is...
