On the distribution of job characteristics: an analysis of the DOT data

We analyse the information in the Dictionary of Occupational Titles to characterize the structure of labour demand. Two dimensions, an intellectual factor and a dexterity factor, capture two-thirds of the variance in job requirements; the remaining (co-)variance cannot be easily structured. Simple linear relationships go a long way in describing the matching between job activities and required worker qualities (Intellect for complex relations to Data and to People, Dexterity for complex relations to Things). There is no dichotomy between mathematical and verbal required skills. Poor working conditions are not restricted to workers in low-level jobs; we find strong support for compensating wage differentials. At more intellectual jobs, men receive less wage compensation for working conditions, while in jobs requiring greater dexterity they receive more. Such a relationship is absent for women.     

Broadening the picture: Negotiating payment schemes for water-related environmental services in the Netherlands

This paper explores how the development of payment schemes for water-related environmental services can be understood and supported. Currently, the development of such payment schemes is perceived mainly through theoretical lenses offered by economists and hydrologists. Notwithstanding the usefulness and appropriateness of these theoretical lenses, they have difficulties to accommodate certain aspects of the development of payment schemes for water-related environmental services. Specifically, the discussion of negotiation aspects remains relatively isolated and superficial, even though it is generally acknowledged that the development of payment schemes is often significantly influenced by political negotiations. This paper addresses this limitation. It shows how the main elements of negotiation analysis can provide a theoretical underpinning for important drivers behind the development of specific payment schemes, which are beyond the scope of hydrological or economic rationality. Four cases of water-related payment schemes in the Netherlands are studied, employing one of the key insights offered by negotiation analysis: the importance of the underlying interests and values of the parties involved. The findings of these four cases show the potential of negotiation analysis as a useful complement for understanding and supporting the development of payment schemes for environmental services.     

The cross-section of stock returns in frontier emerging markets

We are the first to investigate the cross-section of stock returns in the new emerging equity markets, the so-called frontier emerging markets. Our unique survivorship-bias free data set consists of more than 1400 stocks over the period 1997 to 2008 and covers 24 of the most liquid frontier emerging markets. The major benefit of using individual stock characteristics is that it allows us to investigate whether return factors that have been documented in developed countries also exist in these markets. We document the presence of economically and statistically significant value and momentum effects, and a local size effect. Our results indicate that the value and momentum effects still exist when incorporating conservative assumptions of transaction costs. Additionally, we show that value, momentum, and local size returns in frontier markets cannot be explained by global risk factors.     

Both Sides of the Coin: Motives for Corruption Among Public Officials and Business Employees

The aim of this study is to better understand why public officials and business employees engage in corruption. Insight into individual-level explanations for corruption was obtained with the aid of a self-report survey. The results suggest that the most indicative factors of whether or not individuals are corruption-prone are as follows: the moral conviction they have to refrain from corruption; perceptions of whether their colleagues approve of and engage in corruption; and difficulties experienced in complying with the rules on corruption. This result pattern was identical for public officials and business employees alike, and as a consequence, for both sides of corrupt acts. The latter indicates that the same motives may not only underlie corruption in both private and public sectors, but also the act of corruption in its active and passive forms. The results of the current study do not provide strong support for the assumption that economic considerations—expected costs and benefits—are crucial in predicting corruption. Based on the findings that norms and the perceived opportunity to comply are dominant factors in explaining corruption, this article focuses on the practical implications for the development of anti-corruption strategies within both public and private sectors.     

Testing the lawyer-induced litigation hypothesis in Europe

Utilizing a European panel dataset, we contribute to the scant empirical literature on the lawyer-induced litigation hypothesis. To address endogeneity problems that arise when estimating the effect of the number of lawyers on civil litigation rates, we use two strategies. We first estimate our model by means of the 2SLS procedure. Second, we exploit the instrumental variable approach based on the linear GMM estimator of Arellano and Bond. The estimations result in a positive and significant effect of lawyers that is robust across the different model specifications and estimation methods in which we address endogeneity. In criminal litigation, where lawyers cannot induce demand, we find no such positive relation between lawyers and litigation.     

Novel naval technologies: Sustaining or disrupting naval doctrine

The defense sector is generally known to be simultaneously conservative and enthusiastic about novel technologies. Uptake of new technologies by the military may differ depending on the perceived impact of new technologies. Introduction of technological changes can sustain or disrupt doctrine and (promoters of) new technologies may be met with less or more resistance respectively. We analyzed dynamics in naval innovation cases to investigate how different types of technological change became associated with either sustaining or disruptive doctrinal innovations. In order to analyze dynamics in the cases, an analytical framework was developed which highlighted a set of factors shaping naval innovation processes.     

Agro-clusters and Rural Poverty: A Spatial Perspective for West Java

Neighbouring economies are likely to influence one another. The concentration of farming activities referred to as an ‘agro-cluster’ generates opportunities for income and employment in a given region and its surrounding area. We analyse the link between poverty rates and agro-clusters by accounting for spatial spillovers. To quantify agroclusters, we employ one input-oriented and one output-oriented measure. Our analysis applies six spatial econometric specifications and focuses on 545 subdistricts of West Java, where about 10% of the population live in poverty. We find that the concentration of agricultural employment substantially reduces poverty in a subdistrict as well as in neighbouring subdistricts. We also find that specialisation in crop outputs has positive impacts on poverty reduction and that localisation externalities are fundamental to agriculture's success. These findings imply that policy interventions may be applied in a spatially selective manner because they will generate spatial-spillover effects on poverty reduction in surrounding areas.     

IS THE CAPITAL STRUCTURE LOGIC OF CORPORATE FINANCE APPLICABLE TO INSURERS? REVIEW AND ANALYSIS

Since the financial crisis of 2008, next to banks, insurers have received increasing attention from researchers and regulators because of their crucial role in the financial system. A key point for a stable insurer is its capital structure, i.e. the choice between equity, debt and provisions in financing its operations. Based on earlier work a quickly developing literature has directly applied capital structure theories (in particular trade-off and pecking order) from corporate finance to insurers’ financing choices. Corporate finance concepts used herein however, are developed for industrial firms. In this paper we provide an overview of the literature on the capital structure of insurers, but contribute by systematically clarifying how to account for the specificities of insurers when transferring the trade-off and pecking-order logic from an industrial to an insurer context. This way, we add several new insights on an insurer's choice between equity, financial debt and provisions. In particular, we are able to explain why, as compared to industrial firms, insurers use less financial debt, and why insurers focus so strongly on self-financing. Finally, we identify multiple avenues for future research.     

Competition and Local Market Conditions on the Belgian Retail Gasoline Market

The Belgian retail gasoline network is one of the densest in the world and is characterised by a maximum price agreement between the government and the oil industry. Using price data covering almost 500 points of sale located all over Belgium, the price competition among Belgian gas stations is analysed. We observe that stations located along a highway always charge the maximum price. On local markets that are sufficiently competitive, prices are below the maximum price. The analysis further suggests that the number of local competitors does not have a large impact on retail gasoline prices. However, competition is fiercer in the presence of independent gasoline retailers.     

An empirical analysis of university choice and earnings

Summary In this paper we analyze the relations between university choice and earnings. We estimate a model in which a choice function determines the decision to apply to a particular university and thereby the switch to a particular wage regime. The wage structures of the options in turn determine the lifetime earnings prospects associated with those options, and these prospective earnings influence university choice. The results reveal some notable differences between the wage structures of graduates from different universities. In the choice function we find that graduates from different universities differ with respect to social background, gender and the motives that they consider important in choosing a department. A test on the possibility of pooling alternatives establishes heterogeneity of departments. Finally, we find that earnings prospects are not a particularly important factor in the choice of a specific university.
