We consider a simple random walk process, a special case ofthe Martingale model, which exhibits a deterministic break in its drift term,for instance, from positive to negative. This particular example can be aplausible model for a time series on exchange rates which displays a persistentcurrency...

In this paper we consider the situation where the deterministiccomponents of the processes generating individual series are linear trendsand the individual series are independent I(0) or I(1) processes. We showthat when those time series are used in ordinary least squares regression,the...

We derive an explicit formula of the Watts’ poverty index, in terms of parametersof bivariate lognormal distributions of price indices and nominal livingstandards. This result enables us to: analyse the contributions of the distributionsof prices and nominal living standards in poverty;...

A one-to-one link is developed between overlapping sub-regional entities using geographi-cal tools newly available to the Economic Research Community. The aim of this project is tocreate a database exploiting the geographical variation in publicly available data, in order tobetter control for...

Long-run economic growth is analysed in a global model with many small countriesprone to national level total factor productivity shocks. The possibility ofprecautionary saving or dissaving is a function of the higher-order moments and thecross-moments of the factor income distributions, which...

In order to con¯ne excessive levels of temporary layo®s, US ¯rms are taxed - albeit incom-pletely - according to the unemployment insurance bene¯ts claimed by their laid o® workers.In contrast, German construction ¯rms are not charged according to their layo® historyand should thus have...

Significant amount of vertical technology transfer occurs betweendeveloped and developing country firms, yet the literature on intellectual propertyrights did not pay much attention to this aspect...

We hypothesise that, given the typically uneven distribution of ethnic groups within acountry, ethnic diversity leads to greater local polarization and more frequent, butsmaller, conflicts that involve only some ethnic groups. These conflicts can beoverlooked if the number of fatalities is...
