Proxying Ability by Family Background in Returns to Schooling Estimations is Generally a Bad Idea*

When schooling is measured with error and data on ability are lacking, return to schooling estimates will be subject to positive omitted variable bias (OVB) and negative measurement error bias (MEB). We investigate how these biases are affected when ability is proxied by family background variables. We show that the effect on OVB is uncertain, while MEB invariably increases in magnitude. Our empirical analysis demonstrates that MEB generally dominates OVB. With more background variables or increased measurement error, the total bias rapidly becomes negative and increasing in magnitude, thereby driving the return estimate further and further away from the true value.     

The core periphery model with asymmetric inter-regional and intra-regional trade costs

We generalize the model of Krugman (J Polit Econ 99(3):483–499, 1991) to allow for asymmetric trade costs between regions and for (asymmetric) trade costs that are internal to the regions. We find that industrial activity, in a region, is enhanced by higher costs of importing and lower costs of exporting (more precisely, by a higher ratio between the two trade costs). This suggests that countries may impose tariffs on imported goods and seek to remove the import tariffs in other countries (unilateral protectionism) in order to foster industrial activity. Industrial activity is also promoted by lower domestic internal trade costs and higher foreign internal trade costs (more precisely, by a lower ratio between the two trade costs).     

Tender evaluation and supplier selection methods in public procurement

The EU procurement directives stipulate that public contracts be awarded to the lowest bidder or to the bidder with the economically most advantageous tender; the latter requiring that a scoring rule be specified. We provide a simple theoretical framework, based on standard microeconomic theory, for tender evaluation (scoring and weighing) and discuss the pros and cons of methods such as highest quality (beauty contest), lowest price and price-and-quality-based evaluations. We argue that the most common method, price-to-quality scoring, is inappropriate for several reasons. It is non-transparent, making accurate representation of the procurer's preferences difficult. It is often open to strategic manipulation, due to dependence on irrelevant alternatives, and it tends to impose particular and unjustified non-linearity in bid prices. The alternative quality-to-price scoring method, where money values are assigned to different quality levels, is a better alternative. However, when the cost of quality is relatively well-known and several providers can offer optimal quality, lowest price is the preferable supplier selection method, while beauty contests may be preferred when purchasing budgets are inflexible.     

AN ULTIMATUM WAGE BARGAINING EXPERIMENT ON TRADE UNION EFFICIENCY

We present an ultimatum wage bargaining experiment showing that a trade union facilitating non‐binding communication among workers, raises wages by simultaneously increasing employers’ posted offers and toughening the bargaining position of employees, without reducing overall market efficiency.     

The information search process of socially responsible investors

Largely fuelled by an increasing social and ethical concern among private investors, socially responsible investment (SRI) has, in many ways, gone from having a marginal role to becoming a ‘mainstream’ financial service in recent years. SRI is an investment process that, in addition to the ‘traditional’ financial objective of investment, also uses social, ethical or environmental (SEE) criteria when making investment decisions. However, despite the growth of the market for SRI profiled mutual funds, very little research has been carried out with the objective of understanding the decision-making process of private SR-investors. In order to address this gap in the literature, this article addresses one stage in the SR-investor decision-making process: consumer pre-purchase information search. Using a sample of 369 SR-investors, the results of the study indicate that SR-investors search more for SEE information, such as the criteria used for exclusion of stocks than for ‘regular’ financial information such as past financial return and level of risk. Moreover, the study also indicates that involvement and perceived knowledge with regard to both financial and SEE issues impact the nature of the information search process of private SR mutual fund investors.     

Are the determinants of bank loyalty brand specific?

One of the primary concerns of companies is to develop loyal customers, and banks are no exception. Past research attempted to examine the role of satisfaction, perceived quality and image, as drivers of bank brand loyalty. However the characteristics of specific bank brands were not taken into consideration. Using data collected from a sample of 216 retail bank customers, banking with five different banks in Athens Greece, this paper investigates whether similar antecedents could be used to predict brand loyalty in various institutions. The results imply that, depending on the bank, different drivers could influence in a dissimilar manner the formation of loyalty and therefore further research is needed to generalise the suggested models.     

Venture Capital Investment Duration

This paper examines cross‐country evidence on the duration of venture capital (VC) investment. We formulate a theory of VC investment duration based on the idea that venture capitalists exit when the expected marginal cost of maintaining the investment is greater than the expected marginal benefit, and thereby relate VC investment duration to entrepreneurial firm characteristics, investor characteristics, deal characteristics, and institutional and market conditions. VC investment duration data in Canada and the United States lend strong support to the theoretical predictions developed herein.     

Advice and monitoring in venture finance

This paper provides empirical insight into the role of contracts and legal systems for managing investor–investee relationships along two dimensions: providing advice and addressing conflict. We examine a new detailed dataset from European venture capital (VC) funds. We match very specific contractual terms in VC contracts with the effort (total time spent) and advice that VCs provide to their entrepreneurial investee firms. We also analyze VC–entrepreneur conflicts. We compare the importance of contractual versus non-contractual governance mechanisms, as well as the role of legal systems in different countries for facilitating VC–entrepreneur relationships. The data indicate VC cash-flow and control rights significantly facilitating effort and advice that VCs provide to entrepreneurs. VC–entrepreneur conflicts are closely tied to the quality of laws in which the entrepreneur resides: higher quality legal systems mitigate VC–entrepreneur conflicts. The data further indicate that non-contractual governance mechanisms significantly facilitate VC advice and mitigate VC–entrepreneur conflicts. The results provide a unique unifying look into the role of actual VC contracts and legal settings versus non-contractual governance mechanisms, risk, and success potential on VC–entrepreneur relationships in an international context.      

A RARITY SHOW OF MODERNITY: Sweden in the 1920s

This paper redresses a gap in the study of travel literature. It explores a geographical area—Sweden—that has received little scholarly attention, particularly during the period that the paper focuses on; the interwar years. The paper uses ideas of dirt and cleanliness to examine tourist constructions of difference between themselves and other people, as well as to conceptualize modernity. Cleanliness and dirt are themes that have been much discussed in contexts of colonial discourse, but their meanings and functions in a non-colonial setting have not been adequately explored. This paper argues that tourist perceptions of cleanliness and dirt can be used to mediate modernity, race, and the authenticity of cultural experiences.     

Working with concepts in the fuzzy front end: exploring the context for innovation for different types of concepts at Volvo Cars

Automotive firms are balancing the increasing needs for cost and time efficiency with the necessity of developing more innovative products to stand out on in a competitive market. The strive for efficiency has led to an increasingly structured development process with limited allowances for deviations. Previous academic work has pointed out the importance and embedded potential of the fuzzy front end, where new concepts still have the possibility to impact the new product development (NPD) process. However, most research has focused on the transfer of new technologies, while concepts based on e.g. customer or market knowledge have been more or less neglected. This paper discusses the need for alternative and contingent approaches in the front end of NPD to also consider the transfer of other types of concepts. More specifically, it addresses the need to distinguish between different types of concepts and to explore their different prerequisites in NPD. It is argued that customer- and market-based concepts experience certain difficulties due to the history and power of technology in research and development (R&D) domains in the automotive context as well as a lack of support from the existing, formal processes. In this paper, we argue that all new concepts need to be conceptualized before being introduced to the NPD process, but that does not always suffice. Concepts other than technology concepts also need a contingent package to enable an evaluation in the context of the R&D process – they need to be contextualized. This paper draws on an in-depth case study of Volvo Cars within a long-lasting collaborative research setup. It is based on an interview study with key persons in the areas of concept work and NPD, and uses an insider/outsider approach.
