Aid flows are included into the standard cross-country catch-up relation. Robust¬ness of the result is tested by changing time periods and by adding extra variables. The main results are: Absolute conver¬gence and absolute aid effec¬ti¬ve¬ness are both rejected. While conditional...

This Paper analyses the persistence of poverty in Sweden using a hazard rate model based on multiple spells. The model also accounts for unobserved heterogeneity and possibly endogenous initial conditions. We estimate the model on a large representative Swedish panel dataset, LINDA, for the...

Barter in Russia can be explained by firms' liquidity constraint: it is strongly correlated with financial tightness. However, a microeconomic analysis reveals that the rationale behind this liquidity constraint is different according to the firm situation. For firms in a good economic...

The aim of this article is to estimate the technical efficiency of the productive regional sectors and explore the influence of the infrastructure endowments in this analysis. To do this, we used the non parametric approach of DEA to compute Malmquist productivity indexes that allow us to...

In the extant literature either income or consumption expenditures as measured over short periods of time has been regarded as proxies for the material well-being of households. However, economists have long recognized that a household's sense of well-being depends not just on its average income...

This paper investigates whether firms innovate persistently or discontinuously over time using an innovation panel data set on German manufacturing and service firms for the period 1994-2002. We find that innovation behaviour is permanent at the firm-level to a very large extent. Using a dynamic...

The Information and Communication technology(ICT) environment in the economic community of west african states(ECOWAS) has changed sufficiently to warrant re-conceptualization of the earlier initiatives. Notably, many new technologies have emerged, especially in the area of wireless...

In panel data the interest is often in slope estimation while taking account of the unobserved cross sectional heterogeneity. This paper proposes two nonparametric slope estimation where the unobserved effect is treated as fixed across cross section. The first estimator uses first-differencing...

In this paper, we study the limiting distributions for the ordinary least squares (OLS), the fixed effects (FE), first difference (FD), and the generalized least squares (GLS) estimators in a linear time trend regression with a one-way error component model in the presence of serially correlated...
