Inter-market arbitrage in betting

We show that a combined bet at the bookmaker and at the bet exchange market yields a guaranteed positive return in 19.2% of the matches in the top five European soccer leagues. Moreover, we find that all considered bookmakers frequently offer arbitrage positions, and that they experience, on average, negative margins from these postings. Our findings indicate that bookmakers set...

Divide and Conquer: A New Approach to Dynamic Discrete Choice with Serial Correlation

In this paper, we develop a method to efficiently estimate dynamic discrete choice models with AR(n) type serial correlation of the errors. First, to approximate the expected value function of the underlying dynamic problem, we use Gaussian quadrature, interpolation over an adaptively refined grid, and solve a potentially large non-linear system of equations. Second, to evaluate the...

Apprentice pay in Britain, Germany and Switzerland: Institutions, market forces and market power

The pay of metalworking apprentices is high in Britain, middling in Germany and low in Switzerland. We analyse these differences using fieldwork evidence and survey data, drawing on both economic and institutionalist theories. Several institutional attributes influence apprentice pay, partly by affecting supply and demand in markets for training places. Institutional support for...

Effects of training on employee suggestions and promotions: Evidence from personnel records

We evaluate the effects of employer-provided formal training on employee suggestions for productivity improvements and on promotions among male blue-collar workers. Using more than 20 years of personnel data of four entry cohorts in a German company, we address issues such as unobserved heterogeneity and the length of potential training effects. Our main finding is that workers are...

Positive effects of ageing and age diversity in innovative companies - large-scale empirical evidence on company productivity

This article investigates how age diversity within a company's workforce affects company productivity. It introduces a theoretical framework that helps integrate results from a broad disciplinary spectrum of ageing and diversity research to derive empirically testable hypotheses on the effects of age diversity on company productivity. It argues that first the balance between...

The disposition to become an entrepreneur and the jacks-of-all-trades in social and human capital

This paper studies how an individual's composition of human and social capital affects his or her disposition to become an entrepreneur. Our theoretical analysis is an extension of Lazear's (2005) jack-of-all-trades theory in combination with the idea of bricolage of experiences and their effectuation in the disposition to become an entrepreneur. Our primary conclusion is...

Tournament compensation systems, employee heterogeneity, and firm performance

Tournament compensation systems are widely used in practice and have been extensively analyzed theoretically. However, one major problem has hardly been studied in a company context so far: Although it is theoretically well understood that tournament compensation systems are only effective when employees are homogeneous, it has rarely been analyzed what companies can do when they are...

Are all startups affected similarly by clusters? Agglomeration, competition, firm heterogeneity, and survival

Are all startups similarly affected by the survival benefits and drawbacks of locating in geographic clusters? In this paper, we argue that prior theorizing may have missed important contingencies that affect whether a startup experiences the benefits and costs of locating in a cluster. In particular, while the local levels of skilled labor, suppliers, and purchasers have a...

Top management's attention to discontinuous technological change: corporate venture capital as an alert mechanism

Technological discontinuities pose serious challenges to top managers’ attention. These discontinuities, which often occur at the fringes of an industry, are usually driven by innovative and (often) venture capital-backed start-ups creating new products and transforming existing industries in ways that are difficult for incumbent managers to understand against the backdrop of their...
