Market microstructure effects on volatility at the TAIFEX

This study examines whether changes in the frequency of market clearing or changes in trading hours on competing exchanges that use different auction systems affect the volatility of futures prices. In particular, this study exploits a natural experiment in the frequency of market clearing of stock index futures contracts traded on the Taiwan Futures Exchange (TAIFEX) to assess whether successive increases in the frequency of market clearing are associated with changes in the volatility of futures prices. The impact of changes in the trading hours on the TAIFEX and on the competing Singapore Exchange (SGX) where a similar Taiwanese stock index futures contract trades under a continuous auction market regime is also examined. The evidence for the impact of an increase in the frequency of market clearing on volatility is mixed. However, the introduction of simultaneous opening times for the TAIFEX (which batches orders at the open) and the SGX (which does not) is associated with a significant reduction in the volatility in SGX Taiwanese stock index futures prices. © 2007 Wiley Periodicals, Inc.

Revisiting strategic versus non-strategic cooperation

We propose a novel experimental method that disentangles strategically- and non-strategically-motivated behavior. We apply it to an indefinitely-repeated prisoner’s dilemma game to observe simultaneously how the same individual behaves in situations with future interaction and in situations with no future interaction, while controlling for expectations. This method allows us to determine the extent to which strategically-cooperating individuals are responsible for the observed pattern of cooperation in experiments with repeated interaction, including the so-called endgame effect. Our results indicate that the most common motive for cooperation in repeated games is strategic.     

Response to “The Subprime Crisis and African Americans” by Sandra Phillips

Lucy Reuben’s Response to “The Subprime Crisis and African Americans” by Sandra Phillips includes an overview of the linkages between historical housing disparities and the adverse wealth gap from which the African American community suffers. Reuben discusses how the subprime mortgage crisis has reduced both African American homeownership and African American access to wealth-building for entrepreneurial development. Finally, Reuben offers policy recommendations related to expanding financial literacy and strengthening regulatory oversight.     

What a Mess! Participation as a Simple Managerial Rule to 'Complexify' Organizations

This paper adopts a view of organizations as complex adaptive systems and makes a case for making organizations more complex internally through the use of a fairly simple managerial rule – using participative decision making. Participation in decision making enhances connectivity in organizations, which in turn, gives the organization the opportunity to self-organize and co-evolve in more effective ways than when there is minimal connectivity (i.e., autocracy). The paper uses a specific body of research to support the arguments about why participation can benefit the practice of management in modern organizations.
