Integrity and Global Leadership

This paper addresses the role of integrity in global leadership. It reviews the philosophy of ethics and suggests that both contractarianism and pluralism are particularly helpful in understanding ethics from a global leadership perspective. It also reviews the challenges to integrity that come through interactions that are both external and internal to the company. Finally, the paper provides helpful suggestions on how global leaders can define appropriate ethical standards for themselves and their organizations.     

The Nature of Cities: The Scope and Limits of Urban Theory

There has been a growing debate in recent decades about the range and substance of urban theory. The debate has been marked by many different claims about the nature of cities, including declarations that the urban is an incoherent concept, that urban society is nothing less than modern society as a whole, that the urban scale can no longer be separated from the global scale, and that urban theory hitherto has been deeply vitiated by its almost exclusive concentration on the cities of the global North. This article offers some points of clarification of claims like these. All cities can be understood in terms of a theoretical framework that combines two main processes, namely, the dynamics of agglomeration/polarization, and the unfolding of an associated nexus of locations, land uses and human interactions. This same framework can be used to identify many different varieties of cities, and to distinguish intrinsically urban phenomena from the rest of social reality. The discussion thus identifies the common dimensions of all cities without, on the one hand, exaggerating the scope of urban theory, or on the other hand, asserting that every individual city is an irreducible special case.     

Interactivity and Soft Computing in Portfolio Management: Should Farmers Own Food and Agribusiness Stocks?

This article proposes a fully integrated and interactive elicitation-optimization procedure for portfolio management. A soft computing approach based on fuzzy logic is developed as an alternative to the traditional mean variance model and compromise programming approach. The models are applied to farmers to examine whether they should buy publicly traded food and agribusiness firms stocks rather than invest in a broader market stock portfolio. Results suggest that investments in publicly traded food and agribusiness stocks allow farmers to capture additional benefits beyond those of simply diversifying in the broader market.     

Financial Integration and EMU

This paper investigates the effect of European Monetary Union on the integration of the financial services industry within European using data on the announcements of M&A's within the industry. We find some evidence that EMU has helped financial integration within the euro area. In addition, financial institutions in EMU countries became more active in initiating integration between EMU and non‐EMU partners, which also contributed to overall regional integration within European. The more active role of EMU institutions suggests that institutions residing in the eurozone became stronger players in the corporate control market. However, EMU does not facilitate the entry of non‐European institutions into European.     

Permanent income,hedonic prices,and demand for housing: New evidence

Housing demand is examined by looking quite specifically at the income and price variables based on individual household data. Permanent and transitory incomes are computed through instrumental variables related to human and nonhuman wealth. A price is constructed by spatially varying hedonic techniques. Separation of measured income into permanent and transitory components substantially improves the predictive power of the housing demand estimation and leads to demand elasticities of +1 and ?1 with respect to permanent income and price. The permanent income elasticity is roughly twice the measured income elasticity.
