We explore the implications of the differential behavior of total factor productivity across sectors for understanding the dynamics of the relative prices of services and manufactures. We find that, in the second half of the nineties, contrary to the assumptions of the Balassa-Samuelson...

Under imperfect competition in the goods and services markets, price and marginal costs may have different dynamic behaviours. In particular, the dynamic behaviour of markups will depend on current and expected values of future demand. This paper obtains a new series of aggregate (and average)...

After reaching high levels in the 1970s and 1980s, inflation in Spain is significantly lower in the early 2000s. This paper estimates a switching-regime model for that variable. Our results point towards the existence of three regimes across which the average and the volatility of inflation are...

This paper analyses the impact of several factors potentially affecting academic performance of first-year undergraduates (freshers) in Economics at Universidad Carlos III de Madrid during 2002-2005. Outcomes are the grades obtained in three core subjects which differ substantially in their...
