Using panel data from manufacturing firms in Cameroon, this study investigates the impact of Information and Communication Technologies (ICTs) on firms’ productivity in Cameroon. The empirical model is derived from the flexible Translog production function. The strategic complementarities between ICT-capital and organizational changes are accounted for. We estimate our model using the SystemGen...

This paper empirically analyzes the impact of aid on education for about 100 countries over the period 1970-2005. We estimate a system of equations to test whether and to what extent the impact of sector-specific aid on educational attainment depends on (i) the extent to which aid adds to overall educational expenditure of the recipient government, (ii) the strength of the link between governme...

this study attempts to investigate the relationship between pollution and economic growth for two groups of countries according to environmental kuznets curve hypothesis for a sample of 24 developing countries and 26 oecd countries over the period 1980 - 2005. then, we examine this hypothesis using modern econometrics techniques including panel co-integration and panel unit-root. the panel data...

A panel data approach to price-value correlations Abstract Resorting to stationary and non-stationary panel data econometrics we o¤er tests for "Ricardo's 93% theory of value" for 10 OECD countries over di¤erent time ranges. The theory does not …nd empirical support. unit root tests, panel cointegration tests.

Am I Missing Something? The Effects of Absence from Class on Student Performance We exploit a rich administrative panel data-set for cohorts of Economics students at a UK university in order to identify causal effects of class absence on student performance. We utilise the panel properties of the data to control for unobserved heterogeneity across students and hence for endogeneity between abse...

New Zealand has one of the highest asthma prevalence rates among developed countries and previous research attributes this partly to poor socioeconomic conditions and to insufficient home heating in particular. Retrospective empirical studies from overseas suggest that home heating is associated with asthma rates. However, the evidence to date is not conclusive. In this paper, I build a theoret...

Sibling Influence on the Human Capital of the Left Behind While a growing literature has analyzed the effects of parental migration on the educational outcomes of children left behind, this is the first study to highlight the importance of sibling interactions in such a context. Using panel data from the RUMiC Survey, we find that sibling influence on schooling performance is stronger among lef...

preliminary) We examine the role of changes in health on participation decisions of elderly in Mexico using the Mexican Health and Aging Study (2001-2003). A simultaneous equations model accounts for potential endogeneity of health. Preliminary results with a two-stage estimation method suggest that a better health causes a stronger attachment to the labor market, and finds no evidence that emp...

The effect of remittances on capital accumulation remains a contested topic. This paper uses a panel data set from rural Mexico to investigate the impact of remittances on agriculture and livestock investments. After controlling for the endogeneity of migration through an instrumental variable estimation our empirical results show that international migration has a significantly positive effect...

This paper considers the impact of foreign aid for HIV on the number of new infections in low middle income countries . We provide causal estimates by improving on earlier studies by addressing the endogeneity of aid disbursements through the use of instrumental variables. In addition, we effectively control for unobserved country specific effects that might jointly influence aid allocation and...
