This paper investigates the reliability of SVARs in identifying the dynamic effects of news shocks. Using a simple but insightful model with a non-fundamental representation, we show analytically under which conditions SVARs are likely to be successful at identifying news shocks. We find that...

This paper investigates the channels through which remittances affect macroeconomic volatility in African countries using a dynamic stochastic general equilibrium (DSGE) model augmented with financial frictions. Empirical results indicate that remittances—as a share of GDP—have a...

This paper assesses SVARs as relevant tools at identifying the dynamic effects or news shocks, Because of the misalignment between the econometrician and private agents' information sets resulting from foresight the dynamic responses identified from SVARs using either long-run and short-run...

This paper assesses SVARs as relevant tools at identifying the aggregate effects of news shocks. When the econometrician and private agents’ information sets are not aligned, the dynamic responses identified from SVARs are biased. However, the bias vanishes when news shocks account for the...

This paper explores empirically the link between stocks returns Value-at-Risk (VaR) and the state of financial markets across various holding horizons. The econometric analysis is based on a self-exciting threshold autoregression setup. Using quarterly French and US data from 1970Q4 to 2012Q4,...

This paper develops a theory of sequential investments in cybersecurity in which the software vendor can invest ex ante and ex post. The regulator can use safety standards and liability rules as means of increasing security. A standard is a minimum level of safety, and a liability rule states...

This paper studies a dynamic two-sided market in which consumers face switching costs between competing products. I first show that, in a symmetric equilibrium, switching costs lower the first-period price if network externalities are strong. By contrast, switching costs soften price competition...

The New Empirical Industrial Organization (NEIO) literature allows to analyze competition, market power and welfare implications of public policies. This literature is based on the estimation of consumer substitution patterns, that is on the estimation of demand models. Standard discrete choice...
