We examine the relationship between height and reproductive success (RS) in women from a natural fertility population in the Gambia. We observe the predicted trade-off between adult height and age at first birth: women who are tall in adulthood have later first births than short women do. However, tall women have reproductive advantages during the rest of their reproductive careers, primarily in the lower mortality rates of their children. This ultimately leads to higher fitness for taller women, despite their delayed start to reproduction. The higher RS of tall women appears to be entirely due to the physiological benefits of being tall. There is no evidence that female height is related to patterns of marriage or divorce in this population.

The purpose of this chapter is to offer new justification for multiskilling practices such as job rotation and extensive training for broad skills and explain why there appear to exist complementarity between multiskilling and the delegation of decision authority to workers.

By developing a new model of incomplete contracting where workers make noncontractable investments in multiple skills, we obtain the key insight that worker investments in firm-specific human capital become strategic substitutes when their skills overlap each other.

The “skill substitution effect” analyzed in this chapter induces the following three major results, unless specialization offers a substantial technological advantage: (1) workers' incentives to invest in firm-specific human capital tend to be stronger; (2) the optimal level of delegation is typically higher; and (3) firms' ex post profits tend to be higher with multiskilling than with specialization.

The novel implication of the chapter is that multiskilling may be desirable from a firm's viewpoint even if there are no technological or informational task complementarities among the combined skills, which have been believed to be primary reasons for multiskilling in prior works.

Decision-making in human resources management is done at both the micro and macro level of organizations. Unfortunately, the decisions at each level are often executed without consideration of the other, and current theory reflects this issue. In response to a call for integration of micro- and macro-level processes by Huselid and Becker (2011), we review the extant literature on strategic human resources and high-performance work systems to provide recommendations for both research and practice. We aimed to contribute to the literature by proposing the incorporation of the situation awareness literature into the high-performance work systems framework to encourage the alignment of human resources efforts. In addition, we provide practical recommendations for integrating situation awareness and strategic decision-making. We discuss a process for the employment of situation awareness in organizations that might not only streamline human resources management but also result in more effective decisions. Additional considerations include implications for teams, boundary conditions (e.g., individual differences), and measurement.

The importance of tourism for France's economy and society means that proper knowledge of tourism flows is essential. But designing a measuring system and periodic gathering of statistical data raise several difficulties. First, tourism is, by definition, based on movement, and all phenomena involving movement are difficult to measure. Second, there are many different forms of tourism, including holidays and business trips, short and long stays and so forth. Third, the notion of tourism flows has different meanings for those in charge of road, rail or air traffic management, and for those in charge of tourist visits.

This paper first discusses the ambiguities of the notions used in tourism studies. It emphasises the distinction between tourist flows along transportation routes and those in specific places. It then reviews the proper calculation rules for each of the geographical objects used for measuring tourism phenomena, which are primarily lines and areas. It also addresses some of the problems raised by the failure to comply with these rules in published information.

Third, this paper presents the various systems used to measure tourist flows and inflows, and discusses their usefulness and limitations, before discussing some new developments in the field.

Finally, it examines the potential value of modern communication technologies for mobility studies. More specifically, it raises the issue of striking the right balance between statistical accuracy and individual freedom.

Up until recent years, all agricultural production in Norway was strictly regulated through spatial policy (location), production quotas and other price and market regulations. Prices and products were handled by the farmers’ cooperatives. International (e.g. WTO agreements) and domestic pressure has gradually loosened the governmental regulation of chicken and eggs. Economic (e.g. new ownerships), technological (innovations throughout the whole chain), political and institutional (liberalization) and cultural (e.g. in consumption and farming) changes have reconfigured the landscapes of chicken meat production, opening up new opportunities for the chicken industry. Chicken therefore makes a particularly good case for exploring recent major changes in the agri-food system. In this chapter, we investigate evolving rules, risks, challenges and opportunities in and around chicken meat value chains. Empirically, we build on interviews, document studies and statistics on the structural development of the chicken industry and we discuss how these changes are developing in other parts of the Norwegian agri-food system.

This paper explores the nature and causes of the cartel compliance crisis that befell the National Industrial Recovery Act (NIRA) one year after its passage in 1933. We employ a simple game-theoretic model of the NIRA's cartel enforcement mechanism to show that the compliance crisis can largely be explained by changes in expectations, rather than a change in enforcement policy. Specifically, firms initially overestimated the probability that defection would be met with sanction by the cartel's enabling body, the National Recovery Administration – including a consumer boycott resulting from loss of the patriotic Blue Eagle emblem – and complied with the industry cartel rules. As these expectations were correctly adjusted downward, cartel compliance was lost. We support this hypothesis empirically with industry-level panel data showing how output and wage rates varied according to consumer confidence in the Blue Eagle. The analysis provides insight about cartel performance more generally.
