We empirically analyse the impact of trade on income levels in the sub-Saharan Africa countries. The results indicate that the linkage between both variables is negative for these countries. This outcome may explain the negative sign of the Africa dummy in income (or growth) regressions.

This paper proposes and analyses two types of asymmetric multivariate stochastic volatility (SV) models, namely: (i) SV with leverage (SV-L) model, which is based on the negative correlation between the innovations in the returns and volatility; and (ii) SV with leverage and size effect (SV-LSE)...

In this paper we generalize the KPSS-type test to allow for two structural breaks. Seven models have been de?ned depending on the way that the structural breaks a¤ect the time series behaviour. The paper derives the limit distribution of the test both under the null and the alternative...

The detection of additive outliers in integrated variables has attracted some attention recently, see e.g. Shin et al. (1996), Vogelsang (1999) and Perron and Rodriguez (2003). This paper serves several purposes. We prove the inconsistency of the test proposed by Vogelsang, we extend the tests...

As U.S. Treasury securities carry the full faith and credit of the U.S. government, they are free of default risk. Thus, their yields are risk-free rates of return, which allows the most recently issued U.S. Treasury securities to be used as a benchmark to price other fixedincome instruments....

International tourism is the principal economic activity for Small Island Tourism Economies (SITEs). There is a strongly predictable component of international tourism, specifically the government revenue received from taxes on international tourists, but it is difficult to predict the number of...

In this paper we propose an LM-Type statistic to test the null hypothesis of cointegration allowing for the possibility of a structural break, in both the deterministic and the cointegration vector. Our proposal focuses on the presence of endogenous regressors and analyses which estimation...

This paper analyses the main distinctive features of the situations of labour discrimination that women are actually suffering. Men and women play different roles at home, in society and at work. A strong occupational segregation (horizontal and vertical) and serious wage differences between men...

We analyze the effects of the unemployment benefit system on the economy. In particular, we focus on both the tax structure and the unemployment benefits composition. We show that if the unemployment benefit system is only paid by firms, then employment and production are maximized. Moreover,...

The microsimulation models simulate the tax-benefit system for a sample of individuals or households obtained from a microeconomic survey. The results obtained for each household or individual will be used to consider the effects on the tax collection and the distribution of the disposable...
