Modelling the incidence of self-employment has traditionally proved problematic. Whilst the individual supply side characteristics of the self-employed are well documented, the literature has largely neglected (or misspecified) demand side aspects. In this paper we present results from an econometric framework that allows us to separately, and simultaneously, model the supply and demand side ch...

The job search literature suggests that an increase in the proportion of job seekers who are employed reduces the probability of unemployed people finding a job. However, there is little evidence indicating that employed and unemployed job seekers have similar observed characteristics or that they apply for the same jobs. We use the British Labour Force Survey to compare employed and unemployed...

• We study if newly self-employed people accurately predict their future well-being. use individual panel data to compare expected and the realized life satisfaction. Newly are too optimistic about The overoptimism also holds for successful entrepreneurs who remain in business. discuss reasons misprediction such as underestimating heavy workload. formation of expectations is considered a fundam...

Several measures of aromaticity including energetic, magnetic, and electron density criteria are employed to show how aromatic stabilization can explain the stability sequence of hydroporphyrins, ranging from porphin to octahydroporphin, and their preferred hydrogenation paths. The methods employed involve topological resonance energies and their circuit energy effects, bond resonance energies,...

Different methods are available for simultaneous optimization of cross-section, topology and geometry of truss structures. Since the search space for this problem is very large, the probability of falling in local optimum is considerably high. On the other hand, different types of design variables (continuous and discrete) lead to some difficulties in the process of optimization. In this articl...
