Asset market efficiency fosters rational decisions on allocating resources, both individually and socially, and thus helps determine individuals' wealth accumulation and nations' economic growth. To date, however, there are little systematic data available for, and even less analysis of, US...

In this paper we will study the influence of qualitative variables on the unit root tests for stationarity. For the linear regressions involved the implied assumption is that they are not influenced by such qualitative variables. For this reason, after we have introduced such variables, we...

Like several other countries both industrialised and non-industrialised, one of the central objectives of macroeconomic policies in Tanzania is to promote economic growth and to keep inflation at a low level. However, there has been substantial debate on whether inflation promotes or harms...

The occurrence of unit roots in economic time series has far reaching consequences for univariate as well as multivariate econometric modelling. Therefore, unit root tests are nowadays the starting point of most empirical time series studies. The oldest and most widely used test is due to Dickey...

Parents in the labor force have balance their work and home life, including the choice of the type of care to provide for their children while they work. In this paper we study the connection between the married women's labor force participation, child care arrangements and the time that...

We consider an artificial population of forward looking heterogeneous agents making decisions between schooling, employment, employment with training and household production, according to a behavioral model calibrated to a large set of stylized facts. Some of these agents are subject to policy...

The popular impression that Africa has not integrated into world trade, as suggested by the evolution in simple indicators, has been called into question recently by more formal analysis. This paper refines and generalizes this analysis and lends support to the popular view of disintegration,...

The problem of forecasting the economic systems' activity over a large time horizon is the main concern of both the researchers in the economic field and the system managers. In most cases, its solving is reduced to simulating the structure of the economic indicators which render the system...
