Hyperinflation and High Inflation in Venezuela: Monetary or Exchange Rate Origin?

Kyklos, EarlyView.
ABSTRACT From 2018 to 2021, Venezuela experienced a period of intense hyperinflation. There are two hypotheses regarding the origin of such hyperinflation. The monetarist hypothesis attributes hyperinflation to excessive growth in the money supply, typically resulting from public deficits. Alternatively, the structuralist balance of payments hypothesis

On Short‐Term Behavior of Implied Volatility for Index Options

Mathematical Finance, EarlyView.
ABSTRACT This paper investigates short‐term behavior of implied volatility of derivatives written on a market index when the index is constructed using a ranking procedure. Even when stock prices follow geometric Brownian motion dynamics, the ranking mechanism can lead to the observed term structure of at‐the‐money (ATM) implied volatility skew for ...

What Are The Drivers of Labour Productivity in Italy?

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper introduces a novel sign restriction identification within a structural Bayesian vector autoregression (VAR) to analyse how labour productivity responds to supply and demand shocks and to quantify the contribution of shocks to cyclical fluctuations.

Is There an Information Channel of Monetary Policy?

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT Exploiting the heteroskedasticity of the changes in short‐term and long‐term interest rates and exchange rates around the FOMC announcement, we identify three structural monetary policy shocks. We eliminate the predictable part of the shocks and study their effects on financial variables and macro variables.

The Heterogeneous Regional Employment Effects of Environmental Policies

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper examines the effects of Environmental Policies—measured by the OECD Environmental Policy Stringency Index (EPS)—on employment in 349 regions across 26 countries from 1990 to 2020. We find that more stringent EPS have short‐term negative effects on regional employment, which disappear in the medium term.

Weak Exogeneity, Driving Trends and Non‐Causality. Is Dynamic Adjustment Informative About Causality?

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT In VECMs (or CVARs), the weak exogeneity of some of the variables (for the long‐run parameters) is related to the equilibrium adjustment dynamics. This has sometimes led to the statistical concept of weak exogeneity being given a causal interpretation.
