The unfinished history of usage rights for spectrum

The key task in the next stage of spectrum management is to adapt regulation to the prospect of widespread sharing, on a much more sophisticated basis than sharing is used today. There is a role for the regulator to take steps to expand the area of choice within which public and private sector users can operate. This is best done in general by enhancing the flexibility of usage rights, which itself is best achieved by enhancing the freedom to trade them in the dimensions of time, space, level of interference and priority of access, by subdividing, re-aggregating, etc. However, there are considerable transactions cost impediments to trading where unlicensed users are involved. This creates a role for the regulator pro-actively to investigate different allocations, to make provisions for the most promising to occur and to incorporate both in refarming exercises and in primary assignments based on auctions configurations of usage rights, which might favour promising avenues of shared spectrum use.     

Designing a Countercyclical Insurance Program for Systemic Risk

This article proposes a framework for measuring and managing systemic risk. Current solvency regulations have been criticized for their focus on individual firms rather than the system as a whole. We show how an insurance program can be designed to deal with systemic risk through a risk charge on participating institutions. The risk charge is based on the generalized co‐conditional tail expectation, a conditional risk measure adapted from conditional value‐at‐risk. Current regulations have been criticized on the grounds that their capital requirements are procyclical. They require extra capital in periods of extreme stress thus exacerbating a crisis. We show how to construct a countercyclical risk charge and illustrate the approach using a numerical example.     

Effect of internal cost management,information systems integration,and absorptive capacity on inter-organizational cost management in supply chains

Inter-organizational cost management is a strategic cost management approach to managing costs that span organizational boundaries in supply chains. Drawing on the resource-based view of the firm, we develop a model to predict which inter-related resources might enable companies to manage inter-organizational costs. We test this model using a survey of managerial accountants whose organizations are part of a supply chain. Using structural equation modeling, we conclude that the resources of internal electronic integration, external electronic integration, internal cost management, and absorptive capacity play significant direct and indirect roles in the development of an inter-organizational cost management (IOCM) resource. We find that these resources are inter-related and together are useful in enabling companies to ultimately benefit from managing inter-organizational costs. We find in particular the importance of relational resources associated with absorptive capacity in the development of an IOCM resource. Our research contributes to theory and practice by explaining how specific resources can be combined in allowing companies to better manage inter-organizational costs.     

The week-of-the-year effect: Evidence from around the globe

This study investigates another calendar anomaly the literature does not yet address – the week-of-the-year (WOY) effect. Using the weekly returns on the stock market indexes of 20 countries worldwide, for a period that ends in December 2010, the findings demonstrate that returns in Week 44, which starts on October 29 and ends on November 4, are positive in 19 of the 20 countries, and in 18 of them, it is also statistically significant. In contrast, the returns for Week 43, which starts on October 22 and ends on October 28, are negative in 19 of the 20 countries, and statistically significant for most of the countries. We also apply an investment strategy derived from these findings to a prediction period (2009–2010), and find that this strategy beats the simple buy-and-hold policy by a substantial margin.     

Microenterprise Dynamics in Developing Countries: How Similar are They to Those in the Industrialized World? Evidence from Mexico

A rich panel data set from Mexico is used to study the patternsof entry, exit, and growth of microenterprises and to comparethese with the findings of the mainstream theoretical and empiricalwork on firm dynamics. The Mexican self-employment sector ismuch larger than its counterpart in the United States, whichis reflected in higher unconditional rates of entry into thesector. The evidence for Mexico points to the significant presenceof well-performing salaried workers among the likely entrantsinto self-employment, as opposed to the higher incidence ofpoorer wageworkers among the entrants into the U.S. self-employmentsector. Despite these differences, however, the patterns ofentry, survival, and growth with respect to age, education,and many other covariates are very similar in Mexico and theUnited States. These strong similarities suggest that mainstreammodels of worker decisions and firm behavior are useful guidesfor policymaking for the developing-country microenterprisesector. Furthermore, they suggest that, as a first approximation,the developing-country microenterprise should probably be viewedas they are in the advanced countries as offering potentiallydesirable job opportunities to low-productivity workers.     

Investing in Health: A Macroeconomic Exploration of Short-Run and Long-Run Trade-Offs

This paper aims to unravel the competing effects of health investment. It explores, both analytically and numerically, the equilibrium shift and transitional dynamics after a one-time policy of health investment. We find that such a policy improves health status in the long run, but harms economic growth in both the short- and long-term. The relative sizes of these competing effects depend on the specific health parameters. Within the plausible range for the value of health relative to consumption, households gain welfare in the long run as long as the effectiveness of labor in health production is large. The expanded health sector policy makes households worse off only if labor is rather unproductive in producing health and if households value health relatively little. Nevertheless, the findings challenge the policy recommendations of the World Bank (1993) and World Health Organization (2001) in that good health does not necessarily increase the productivity of workers and the economic growth rate. We hope that the relative simplicity of our model, compared to the existing theoretical literature, can help close the gap between formal academic work on this topic and actual debates among policy makers in both developed and developing countries.     

Perception of Risks and Preferences for Locally Grown Produce: A Marketing System Approach

In recent years, the “buy local” movement has escalated in popularity. This trend is redefining how value along the food chain is shared between producers, retailers, and consumers. A theoretical model was developed and used to evaluate how consumers formulate preferences for locally grown attributes, with an emphasis on consumers’ perceptions of food safety risk. Linkages between locally grown produce attributes, perceived macro outcomes, and value allocation to consumers are then examined using random utility discrete choice models. While results were mixed depending on frequency of purchasing locally grown produce, they do indicate that consumer preferences are driven by perceived food safety risk and other macro outcomes. For example, consumers who frequently purchase locally grown produce perceive these products to be environmentally friendly and to improve their quality of life.     

Standards across borders: crossborder diffusion of the arm's length standard in North America

The arm's length standard is used by corporate income tax authorities to price international intracorporate transactions and allocate intracorporate income and expenses of multinational enterprises. In this paper, we examine the socio-historical evolution of transfer pricing regulation in North America. We develop a model of crossborder diffusion of standards, using institutional theory and the logic of embeddedness, that focuses on three components of crossborder diffusion: timing, motivation and form. Our model is then applied to the evolution and diffusion of the arm's length standard within North America from 1917 to the present.
