This paper analyses the effect of risk attitudes of firm owners on profits among micro and small enterprises (MSEs) in Lagos, Nigeria. Higher risk perceptions are shown to have a significant positive effect on profits, whereas risk propensity has a negative or no effect. Education, age, being...

Existing studies show a positive relationship between entrepreneurs' business performance and their conventional human capital as measured by previous business experience and formal education. In this paper, we explore whether illegal entrepreneurship experience (IEE), an unconventional form of...

This study analyses 1400 research projects of the top 20 R&D-spending pharmaceuticals to identify the determinants of successful research projects. We provide clear evidence that externally sourced projects and projects involving biotechnologies perform better than internal projects and chemical...

This paper analyses the effect of uncertainty on investment spending. We analyse two types of investment, i.e. aggregate investment and investment in energy saving technologies, using subjective evaluations of expectations and uncertainty of Dutch firms in 1997. We estimate several models...

This paper examines the effects of specialisation (within-sector clustering) and diversity (between-sector clustering) on business services profitability and location choice. We apply a semiparametric Poisson sorting model allowing for firm-specific effects. We find that for most firms,...

This paper extends Hotelling's model of price competition with quadratic transportation costs from a line to graphs. I propose an algorithm to calculate firm-level demand for any given graph, conditional on prices and firm locations. One feature of graph models of price competition is that...

Why has job growth over the past decades been weaker in the Dutch Randstad area than in surrounding regions? In a simultaneous equations analysis, we find that employment adjusts to the regional supply of labour. Net internal migration is predominantly determined by regional housing supply and...

We test a new model where the entrepreneurial decision is described as a process of successive engagement levels, i.e., as an entrepreneurial ladder. Five levels are distinguished using nearly 12,000 observations from the 2004 “Flash Eurobarometer survey on Entrepreneurship” covering the 25...

This paper replicates Costa and Kahn's analysis of locational choices of couples of highly educated persons for the Netherlands. We find increasing concentration of such power couples in the urbanized western part of the country. This trend occurs in spite of the absence of an urban wage premium...

Existing indices measuring the spatial distribution of economic activity such as the Krugman Specialisation Index, the Hirschmann-Herfindahl index and the Ellison-Glaeser index typically do not take into account the spatial structure of the data. In this paper, we first consider traditional...
