Settlement procedures and stock market efficiency

This study examines why most derivatives markets that settle on the day following expiration choose the opening rather than the closing price as the final settlement price (FSP), whereas most markets that settle on the expiration day select an average rather than a single price as the FSP. Four exogenous changes in the Taiwan Futures Exchange settlement procedures provide an experimental basis for studying the settlement procedures’ impact on underlying assets. Greatest market efficiency is observed when the FSP is determined by a single rather than an average price and hypothesize that manipulation is prevented at the expense of market quality.     

Auditors,Specialists, and Professional Jurisdiction in Audits of Fair Values

Auditors frequently use valuation specialists to help them evaluate fair values, but researchers and regulators know little about how auditors use these specialists. Based on interviews with 28 auditors and 14 valuation specialists, I develop a theoretical framework informed by expert systems and professional competition theories. The interviews suggest that institutional pressures in the fair value environment unevenly impact auditors and specialists, causing tension between auditors' needs for ontological security and jurisdictional claims. This tension leads to one-sided competition between auditors and specialists and incomplete acceptance of specialists' work. Auditors' competitive behaviors coupled with this incomplete acceptance result in a tendency to make specialists' work conform to auditors' views. Collectively, these findings suggest that auditors use specialists as an institutional mechanism to create comfort, but not insight. This study links expert systems and professional competition theories, and it provides critical insight into some assumptions underlying tenets of each theory. It also informs researchers, regulators, and practitioners interested in understanding and addressing problems related to the use of specialists.     

Entrepreneurial Hustle: Navigating Uncertainty and Enrolling Venture Stakeholders through Urgent and Unorthodox Action

Entrepreneurs need to act under conditions of uncertainty and resource constraints to bring new, often-unrecognizable products to market and convince an unknown set of stakeholders to support their endeavours. The type of action entrepreneurs take to navigate uncertain entrepreneurial contexts is underspecified. We analysed 48 interviews with entrepreneurs to inductively identify an action-oriented construct we labelled as entrepreneurial hustle – an entrepreneur’s urgent, unorthodox actions that are intended to be useful in addressing immediate challenges and opportunities under conditions of uncertainty. In a follow-up study, we use an experimental vignette approach to assess the impact of an entrepreneur’s hustle on venture stakeholders. Findings suggest that entrepreneurial hustle positively influences stakeholder perceptions of the entrepreneur’s leadership effectiveness and a venture’s legitimacy, mediated by perceptions of the entrepreneur’s ability-based trustworthiness. We conclude that entrepreneurial hustle is a fundamental behaviour that enables entrepreneurs to enrol new venture stakeholders and lead their entrepreneurial efforts.     

Will We Ever Meet Again? The Relationship between Inter-Firm Managerial Migration and the Circulation of Client Ties

A large body of research shows that the migration of managers from one professional service firm to another weakens the old employer’s relationship with its clients, because migrating managers remove their relationship-specific knowledge and expertise – i.e., human and social capital – from their old employers, redeploying it to their new employers. This study extends this research by introducing a bi-directional perspective of social capital in which both firms and managers may exploit these relationship-specific resources. We use theory on social capital to build arguments about how one form of manager mobility, manager migration between two service providers in a single market, can both lead and lag the movement of client ties between those providers, and signaling theory to hypothesize the conditions under which this is likely to occur. Analyses using longitudinal data on New York City advertising agencies generally support our arguments. Our findings contribute to theory and research on manager migration, social capital, and signaling, and raise new questions for how the portability of relationship-specific social capital shapes markets.     

Social Marketing of a Fortified Staple Food at Scale: Generating Demand for Fortified Rice in Brazil

ABSTRACT

This paper describes the social marketing strategy implemented by PATH and GAIN to create a sustainable market for rice fortification in Brazil and develop a replicable model relevant to other geographies. It draws on market research on consumer attitudes and practices, as well as key demand and consumer metrics before and after execution of the social marketing campaign in Brazil. This marketing endeavor succeeded in establishing the viability of introducing fortified rice in a country through a purely market-based approach. Whereas social marketing is vital to the introduction and scale-up of fortified staple foods through commercial markets, it is not sufficient to achieve meaningful scale and sustainability. Engagement from the public and social sectors, clear governance, and other factors are critical to substantial and long-term impact. Lessons from this first attempt to introduce a fortified staple food through a market-based approach are relevant to similar initiatives elsewhere.     

Data-driven tree structure for PIN models

Probability of informed trading (PIN) models characterize trading with certain types of information through a tree structure. Different tree structures with different numbers of groups for market participants have been proposed, with no clear, consistent tree used in the literature. One of the main causes of this inconsistency is that these trees are artificially proposed through a bottom-up approach rather than implied by actual market data. Therefore, in this paper, we propose a method that infers a tree structure directly from empirical data. More precisely, we use hierarchical clustering to construct a tree for each individual firm and then infer an aggregate tree through a voting mechanism. We test this method on US data from January 2002 for 7608 companies, which results in a tree with two layers and four groups. The characteristics of the resulting aggregate tree are between those of several proposed tree structures in the literature, demonstrating that these proposed trees all reflect only part of the market, and one should consider the proposed empirically driven method when seeking a tree representing the whole market.

     

Entrepreneurial beacons: The Yale endowment,run‐ups,and the growth of venture capital

Research summary : This article investigates the social context of entrepreneurship in organizational sectors. Prior research suggests that firm foundings are driven by collective patterns of activity—such as patterns of prior foundings in a given sector. Building on research on social salience and signals, we consider the influence of singular sector‐level triggers, which we call entrepreneurial beacons. We argue that the actions or outcomes of single, salient organizations attract and motivate entrepreneurs, thus increasing the rate of foundings. We test this logic by examining the impact of the Y ale U niversity endowment's investment choices and of venture‐capital‐backed IPO run‐ups on venture‐capital foundings between 1984 and 2011. We find support for the existence and influence of beacons and outline boundary conditions for their effects . Managerial summary : What leads entrepreneurs to found new companies in nascent sectors? In contrast to prior research, which emphasizes patterns of activity, we argue that entrepreneurial activity can sometimes be driven by the actions of a singular trigger—what we call an entrepreneurial beacon. We examine the influence of two such beacons, Y ale U niversity's endowment investments and exceptional venture‐capital‐backed IPO run‐ups, on the founding of new venture‐capital firms over a 28‐year period. We find that Y ale's increased allocations to the venture‐capital asset‐class has a significant influence on the founding of new venture‐capital firms, while exceptional venture‐capital‐backed IPO run‐ups only influence venture‐capital foundings under certain conditions. Overall, we offer an explanation for heretofore anecdotal accounts of certain organizations or events that appear to have an outsized influence on entrepreneurial activity .

Improving the speed of adoption of agricultural technologies and farm performance through farmer groups: evidence from the Great Lakes region of Africa

The article examines the effect of membership in farmer groups (MFG) on adoption lag of agricultural technologies and farm performance in Burundi, the Democratic Republic of Congo and Rwanda. We use duration and stochastic production frontier models on farm household data. We find that the longer the duration of MFG, the shorter the adoption lag and much more so if combined with extension service delivery. Farmer groups function as an important mechanism for improving farm productivity through reduced technical inefficiency in input use. We discuss policy implications under which farmer groups are a useful channel to reduce adoption lag, and the means through which improved farm performance can be achieved.
