We use the Kalman filter to estimate the structure of the secret currency basket of the renminbi based on daily data between 2005 and 2009. The currency weights of selected currencies are modeled as stochastic processes (random walks). The official announcement of the new exchange rate regime in...

Interest-rate spreads fluctuate widely across time and countries. We characterize their behavior using some 3,200 quarterly observations for 21 advanced and 17 emerging economies since the early 1990s. Before the financial crisis, spreads are 10 times more volatile in emerging economies than in...

One of the most important controversies in health economics concerns the question whether the imminent aging of the population in most OECD countries will place an additional burden on the tax payers who finance public health care systems. Proponents of the "red-herring hypothesis" argue that...

We estimate Okun's law, the negative relationship between output and the unemployment rate, at the sector level for the US, the UK, Japan, and Switzerland to test several hypotheses that may explain why the aggregate Okun's coeffcients are different across countries. Specifically, we show that...

This paper examines the advantages and drawbacks of alternative methods of estimating oil supply and oil demand elasticities and of incorporating this information into structural VAR models. I not only summarize the state of the literature, but also draw attention to a number of econometric...

This paper examines the impact of labour and product market reforms on economic growth in 25 OECD countries between 1985 and 2013, and tests whether this impact is conditioned by the fiscal policy stance, i.e. whether there are fiscal expansions or adjustments. Our local projection results...

This paper analyses the impact of the Covid-19 pandemic on exports and imports in the case of 35 OECD countries during the 2019Q1-2021Q2 period using a dynamic panel approach, specifically the system Generalized Method of Moments (GMM). In contrast to earlier studies, the empirical specification...
