Time Deposits,Dimensions, and Fraud

We stipulate, arguendo, that fractional-reserve-demand deposit banking is per se fraudulent. We ask whether or not time deposit banking can also be illicit, and answer in the positive, if there is a mismatch between the time dimensions of deposits and loans. To wit, if an intermediary borrows short and lends long.     

The business case for commitment to diversity

Does an organization's commitment to diversity - as reflected by CEO commitment, human capital, corporate communications (internal and external), and supplier diversity - result in competitive advantage and superior financial performance? Diversity can bring new voices and perspectives into the strategy dialogue, help managers understand and address the needs of a demographically diverse customer base, and stimulate a wider range of creative decision alternatives. However, the anticipated benefits of corporate diversity efforts may also be accompanied by costs that can affect shareholder wealth. In a study comparing the financial performance of the DiversityInc Top 50 Companies for Diversity to a matched sample, we find evidence that firms with a strong commitment to diversity outperform their peers on average. For commitment to diversity to become ingrained in corporate culture there must be visible and ongoing support from senior management, a clear articulation of the business case for diversity, line manager accountability, and training programs directed at communications, conflict resolution, and team building.     

Transversals, systems of distinct representatives, mechanism design, and matching

A transversal generated by a system of distinct representatives (SDR) for a collection of sets consists of an element from each set (its representative) such that the representative uniquely identifies the set it belongs to. Theorem 1 gives a necessary and sufficient condition that an arbitrary collection, finite or infinite, of sets, finite or infinite, have an SDR. The proof is direct, short. A Corollary to Theorem 1 shows explicitly the application to matching problems. In the context of designing decentralized economic mechanisms, it turned out to be important to know when one can construct an SDR for a collection of sets that cover the parameter space characterizing a finite number of economic agents. The condition of Theorem 1 is readily verifiable in that economic context. Theorems 2–5 give different characterizations of situations in which the collection of sets is a partition. This is of interest because partitions have special properties of informational efficiency.     

Risk sensitive asset management with transaction costs

This paper develops a continuous time risk-sensitive portfolio optimization model with a general transaction cost structure and where the individual securities or asset categories are explicitly affected by underlying economic factors. The security prices and factors follow diffusion processes with the drift and diffusion coefficients for the securities being functions of the factor levels. We develop methods of risk sensitive impulsive control theory in order to maximize an infinite horizon objective that is natural and features the long run expected growth rate, the asymptotic variance, and a single risk aversion parameter. The optimal trading strategy has a simple characterization in terms of the security prices and the factor levels. Moreover, it can be computed by solving a {\it risk sensitive quasi-variational inequality}. The Kelly criterion case is also studied, and the various results are related to the recent work by Morton and Pliska. Mansucript received: July 1998; final version received: January 1999     

The Pattern of Intraday Portfolio Management Decisions: A Case Study of Intraday Security Return Patterns

This article examines causes of observed stock trading patterns that show high hourly returns and trading volume during early and late trading hours. Using time-stamped data from an institutional investor, we document high levels of portfolio managers' early-morning and late-afternoon decisions to trade that can result in the volume pattern and relatively higher proportions of buy decisions that could contribute to the return pattern.     

Funding the story of hybrid ventures: Crowdfunder lending preferences and linguistic hybridity

Prosocial crowdfunding platforms are venues for individual lenders to allocate resources to ventures that specifically pursue economic and social value. In a setting where hybridity is expected, do crowdfunders respond positively to category-spanning ventures, or do they prefer to fund ventures that are more clearly situated within a single category? Drawing on theory rooted in category membership and spanning, our hypotheses test whether prosocial crowdfunding lenders will more quickly allocate resources to hybrid microenterprises that communicate their hybridity, or to those that communicate a single one of their dual aims. Our study demonstrates that even in such a setting, crowdfunders lend more quickly to microenterprises that position themselves within a single linguistic category in which the social is emphasized over the economic. This suggests that how hybrid organizations position themselves in their linguistic narratives has a significant impact on resource allocation by external prosocial audiences.     

Positioning strategies for branding services in an emerging economy

ABSTRACT

The concept paper adopts a positioning type for the purpose of branding services in a transitioning economy. The consumer-based typology is deemed appropriate and relevant as it represents consumer expectations, reflecting the paper’s key argument that consumer-based positioning strategies are appropriate for branding purposes. Consequently, the paper adopts a positioning type for illustrative purpose. The three positioning strategies adopted were—‘service reliability’, ‘social responsibility’, and ‘branding’ apply to the Ghanaian context. The ‘service reliability’ strategy has a ‘universal’ appeal and is the most prevalent in application. The ‘social responsibility’ to a large extent reflects the caring and community-based nature of the Ghanaian society, whilst the ‘branding’ strategy appears more applicable to international than local firms. The paper contributes to theoretical knowledge in its key assertion that the application of consumer-based positioning strategies for branding is appropriate and beneficial. Practically, the derived propositions will guide the manager in decision making on branding.     

Getting From ‘Me’ to ‘We’: Role Clarity,Team Process,and the Transition From Individual Knowledge to Shared Mental Models in Employee Dyads

Shared mental models are crucial for team functioning; however, little research to date has focussed on uncovering the predictors of shared mental models. The present study investigates the effect of role clarity on shared mental models by means of its indirect effects via team process. Two hundred and two undergraduate students participated in a dyadic firefighting simulation in which their role clarity, team process, and mental model similarity were measured. Analyses conducted at the dyadic level suggest that role clarity predicts mental model similarity via its effects on team process. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.     

Damage control for new corporate ventures.

In the aggregate, corporations lose billions on new ventures. Here's a venture cost management program that can save fortunes by keeping the cost of losers down while accelerating the success of the winners.
