This paper attempts to quantify the effect of skill shortages on the UK labour market by developing a simultaneous equation model of unemployment and real wage growth. The model is developed following a structural approach based on a priori economic information and is initially estimated using a two-stage least squares procedure. The model is also estimated using Zellner’s seemingly unrelated r...

Adequate supply of energy is important for sustainable growth in an economy. The rate the Nigeria’s electricity development very slow and not effective compare to other emerging economies; this on hands has discouraged production, most especially manufacturing sector. In light this, study investigates long-run impact consumption sector performance proxy by output, employment capital using Canon...

We estimate the effect of motherhood on wages using matching. We distinguish between net and direct effects. The net effect includes the total wage costs, whereas the direct represents the causal effect. Since covariates are likely affected by motherhood, the latter effect is not immediately uncovered. We therefore implement two strategies: First, we confine the analysis to consider sector-spec...

The relationship between technology and international competitiveness dates back to the neo-technological trade theories of the 1960s. This approach considers difference in technology as the primary motive for difference among nations in terms of trade performance. The technology gap approach emphasizes inter-country differences in innovativeness as the basis for international trade flows. The ...

the gravity method is one of the first geophysical techniques used in oil and gas exploration. an algorithm is developed for a fast quantitative interpretation of gravity data generated by geometrically simple but also the estimated depths and other model parameters of a buried structure. following abdelrahman et al (1989). the general gravity anomaly expression produced by a sphere, an infinit...
