La croissance de la productivité est examinée par les macro-économistes car elle joue des rôles clés dans la compréhension de l'épargne dans le secteur privé, les sources des chocs macroéconomiques, l'évolution de la compétitivité internationale et la solvabilité des régimes de...

Data revisions in macroeconomic time series are typically studied in isolation ignoring the joint behaviour of revisions across different series. This ignores (i) the possibility that early releases of some series may help forecast revisions in other series and (ii) the problems statitical...

A well-documented property of the Beveridge-Nelson trend-cycle decomposition is the perfect negative correlation between trend and cycle innovations. We show how this may be consistent with a structural model where trend shocks enter the cycle, or cycle shocks enter the trend and that...

This paper derives analytical gradients for a broad class of regime-switching models with Markovian state-transition probabilities. Such models are usually estimated by maximum likelihood methods, which require the derivatives of the likelihood function with respect to the parameter vector....

The authors document a robust and interesting relationship between the real domestic price of oil and real effective exchange rates for Germany, Japan and the United States. They explain why they think the real oil price captures exogenous terms-of-trade shocks and why such shocks could be the...

This paper uses regime-switching econometrics to study stock market crashes and to explore the ability of two very different economic explanations to account for historical crashes. The first explanation is based on historical accounts of quot;manias and panics.quot; Its key features are that...

Several recent papers have presented evidence from foreign exchange and other markets suggesting that the log of excess returns can be characterized as first-order integrated processes (I(1)). This contrasts sharply with the quot;conventionalquot; wisdom that log prices are integrated of order...

This paper tests between fads and bubbles using a new empirical strategy (based on switching-regression econometrics) for distinguishing between competing asset-pricing models. By extending the Blanchard and Watson (1982) model, we show how stochastic bubbles can lead to regime-switching in...

The surge in fiscal deficits since 2008 has put a renewed focus on the authors’ understanding of fiscal policy. The interaction of fiscal and monetary policy during this period has also been the subject of much discussion and analysis. This paper gives new insight into past fiscal policy and...

This paper develops a new test for speculative bubbles, which is applied to data for the Japanese yen, the German mark and the Canadian dollar exchange rates from 1977 to 1991. The test assumes that bubbles display a particular kind of regime-switching behaviour, which is shown to imply...
