We study the role of reciprocity in a labour market field experiment. Recently, many experiments have been conducted to test the extent to which cash and non-monetary gifts affect workers’ productivity through social exchange. Our experiment concluded that non-monetary gifts are more effective...

Econometric Methodology is based on logical positivist principles. Since logical positivism has collapsed, it is necessary to re-think these foundations. We show that positivist methodology has led econometricians to a meaningless search for patterns in the data. An alternative methodology which...

An analysis of the ability of employers to provide care and attention as a way to motivate their employees is done. Workers not only compare their wages, as pointed out in previous literature, but also compare the socio-emotional resources provided by their employer. This provides important...

Models are representations of reality. They simplify and ignore many complexities in order to focus on certain aspects. With constant and repeated use, theorists sometimes confuse the model with reality. This leads to many types of errors. In this article, we argue that the metaphor of the...

Current economics textbooks and neoclassical economists justify a theory of consumer behaviour based on utility maximisation on a priori grounds. This methodology follows Lionel Robbins' idea that economic theory is based on logical deduction from postulates which are "simple and indisputable...

Applied econometric work takes a superficial approach to causality. Understanding economic affairs, making good policy decisions, and progress in the economic discipline depend on our ability to infer causal relations from data. We review the dominant approaches to causality in econometrics, and...

The large majority of the criteria for model selection are functions of the usual variance estimate for a regression model. The validity of the usual variance estimate depends on some assumptions, most critically the validity of the model being estimated. This is often violated in model...
