The innovation consequences of mandatory patent disclosures

We investigate the effect of patent disclosures on corporate innovation. Using the American Inventor's Protection Act (AIPA) as a shock that increased patent disclosures, we find an increase in innovation for firms whose rivals reveal more information after the AIPA and a decrease in innovation for firms whose own disclosures are divulged to competitors as a result of the law. These findings suggest patent disclosures generate both spillover benefits and proprietary costs. Our findings provide justification for patent disclosure requirements by demonstrating positive externalities: rivals' disclosures facilitate a firm's innovation. However, we also highlight that mandatory patent disclosures can impose proprietary costs on firms. These results broadly contribute to our understanding of the real effects of disclosure, such that forcing firms to share proprietary information can be privately costly but beneficial to other firms.     

ASSET ALLOCATION AND ANNUITY-PURCHASE STRATEGIES TO MINIMIZE THE PROBABILITY OF FINANCIAL RUIN

In this paper, we derive the optimal investment and annuitization strategies for a retiree whose objective is to minimize the probability of lifetime ruin, namely the probability that a fixed consumption strategy will lead to zero wealth while the individual is still alive. Recent papers in the insurance economics literature have examined utility-maximizing annuitization strategies. Others in the probability, finance, and risk management literature have derived shortfall-minimizing investment and hedging strategies given a limited amount of initial capital. This paper brings the two strands of research together. Our model pre-supposes a retiree who does not currently have sufficient wealth to purchase a life annuity that will yield her exogenously desired fixed consumption level. She seeks the asset allocation and annuitization strategy that will minimize the probability of lifetime ruin. We demonstrate that because of the binary nature of the investor's goal, she will not annuitize any of her wealth until she can fully cover her desired consumption with a life annuity. We derive a variational inequality that governs the ruin probability and the optimal strategies, and we demonstrate that the problem can be recast as a related optimal stopping problem which yields a free-boundary problem that is more tractable. We numerically calculate the ruin probability and optimal strategies and examine how they change as we vary the mortality assumption and parameters of the financial model. Moreover, for the special case of exponential future lifetime, we solve the (dual) problem explicitly. As a byproduct of our calculations, we are able to quantify the reduction in lifetime ruin probability that comes from being able to manage the investment portfolio dynamically and purchase annuities.     

Japanese women in management: Where are they?

The two economic superpowers, Japan and the United States, have different patterns of contribution by their female populations. The authors travelled to Japan to research and observe firsthand the contributions made and the roles filled by the Japanese female. A comparison of costs and benefits to each country created by the different roles of females is discussed. Questions such as the following are explored:

• Does the Japanese female contribution to child-rearing and nurturing of new coporate members outweigh her lost contribution to the workplace?
• Has the United States gained or lost ground economically due to women integrating the American workplace?
• Will Japanese women be content to be on the fringes of the economic system for another generation?
• What is the likely future scenario for the workplace for both economic superpowers?

     

Globalization and the connection of remote communities: A review of household effects and their biodiversity implications

The remote regions of the world provide refuge to a disproportionate amount of the Earth's biodiversity. As globalization continues, isolated human communities in these regions are increasingly connected to global market, migration, and technology networks. We review the diffuse literature on the household effects of changing market access, migration, and technology adoption in remote regions and implications for native biodiversity. Market access affects biodiversity in remote communities through changes in household economics and social networks. Migration, either to or from remote settlements, affects biodiversity through changes in population, remittances, human capital, and social networks. Finally, we consider effects due to production, public infrastructure, and information and communication technologies. There is much ambiguity surrounding these causal pathways, and thus we also examine the roles of various ecological, household, community, and institutional mediating factors in determining the impacts of global connection. Finally, we explore the limitations of our current knowledge and research practices and propose directions for future work to address key uncertainties in theory and evidence as well as weaknesses in methodological approaches. We recommend a broad and interdisciplinary mode of inquiry as the best means toward clarifying globalization's impacts on human settlements and the biodiversity harbored in the Earth's remaining remote regions.     

Gender,Organizational Justice Perceptions,and Union Organizing

The authors examine the relationship between gender and organizational justice perceptions and the implications of this relationship for organizing women. They employ a survey study design to confirm expectations associated with the anecdotal literature on this topic, namely that women place greater value on interactional justice than on distributive or procedural justice. Results indicate that gender leads to valuing interactional justice more highly only in interaction with race. Specifically, in contrast to white women and both white and black men, black women give greater weight to being treated with dignity and respect than to the other two organizational justice dimensions.
