The paper uses panel data on OECD countries to assess four theories about the forces that generate social spending. The four theories are: Aid: the Welfare State is about helping the poor. Insure: the Welfare State insures the consumption of middle-class voters. Transfer: the Welfare State...

We explore the long and short run relationship between private consumption, disposable income and housing and financial wealth approximated by price indices for a panel of industrialized countries. Consumption, income and wealth are cointegrated in their common, but not in their idiosyncratic...

This paper examines the degree of persistence of youth unemployment (total, male and female) in twenty-four countries by using two alternative measures: the AR coefficient and the fractional differencing parameter, based on short- and longmemory processes respectively. The evidence suggests that...

This paper investigates the degree of persistence of market fear. Specifically, two different long-memory approaches (R/S analysis with the Hurst exponent method and fractional integration) are used to analyse persistence of the VIX index over the sample period 2004-2016, as well as some...

This paper considers the question of whether changes in persistence have occurred during the long-run evolution of U.S. prices of the non-renewable energy resources crude oil, natural gas and bituminous coal. Our main contribution is to allow for a structural break when testing for a break in...

We consider structural vector autoregressions identified through stochastic volatility. Our focus is on whether a particular structural shock is identified by heteroskedasticity without the need to impose any sign or exclusion restrictions. Three contributions emerge from our exercise: (i) a set...

This paper examines the day of the week effect in the crypto currency market using a variety of statistical techniques (average analysis, Student's t-test, ANOVA, the Kruskal- Wallis test, and regression analysis with dummy variables) as well as a trading simulation approach. Most crypto...

This paper investigates the heterogeneous responses of exporters to policy reforms undertaken by the People’s Bank of China to internationalize the Renminbi (RMB). Using detailed customs data from France for the initial years of these reforms (2011-2017), it documents several novel stylized...

We develop a composite indicator measuring the performance of national innovation systems. The indicator takes into account both "hard" factors that are quantifiable (such as R&D spending, number of patents) and "soft" factors like the assessment of preconditions for innovation by managers. We...

We address the pitfalls of averaging by exploiting the longitudinal variation in aid to identify sudden and sharp increases in aid flows. Focusing on specific events, we test if aid accelerations correspond to policies and shocks in the recipient country. For a large sample of 145 recipient...
