A model which explains data that is subject to sudden structural changes of unspecified nature is presented. The structural shifts are generated by a random walk component whose innovations belong to the normal domain of attraction of a symmetric stable law. To test the model against the...

We examine the properties of several residual-based cointegration tests when long run parameters are subject to multiple shifts driven by an unobservable Markov process. Unlike earlier work, which considered one-off deterministic breaks, our approach has the advantage of allowing for an...

We re-examine the empirical relevance of the cost channel of monetary policy (e.g. Ravenna and Walsh, 2006), employing recently developed moment-conditions inference methods, including identiÂ…cation-robust procedures. Using US data, our results suggest that the cost channel effect is poorly...

When entering the market, orphan drugs are associated with substantial prices and a high degree of uncertainty regarding safety and effectiveness. This makes decision making about the reimbursement of these drugs a complex exercise. To advance on this, the Dutch government introduced a...

We measure the success of fiscal consolidation, with alternative definitions, based on <italic>ad-hoc</italic> quantitative approaches and on a policy-action approach. The cyclically adjusted primary balance, and the duration of the consolidation contribute for its success, and the opposite applies for...

In a cross section of OECD countries, we replace the macroeconomic production function by a production possibility frontier, total factor productivity being the composite effect of efficiency scores and possibility frontier changes. We consider, for the periods 1970, 1980, 1990 and 2000 one...

We assess the fiscal composition-growth nexus, using a large country panel, accounting for the usually encountered econometric pitfalls. Our results show that revenues have no significant impact on growth whereas expenditures have negative effects. The same is true for the OECD with the addition...

We use a panel of developed and emerging countries for the period 1970 to 2008 to assess the cyclicality of education, health and social security government spending. We mostly find acyclical behaviour, but evidence also points to counter-cyclicality for social security spending, particularly in...

We use a panel of developed and emerging countries for the period 1970 to 2008 to assess how fiscal policy volatility and financial crises affect growth. We find that economic growth is lower in the presence of more volatile fiscal policy. Moreover, with a financial crisis government spending is...
