Analyst Report Readability

Using an extensive database of 356,463 sell‐side equity analysts' reports from 2002 to 2009, this study is one of the first to analyze the readability of analysts' reports. We first examine the determinants of variations in analyst report readability. Using several proxies for ability, we show that reports are more readable when issued by analysts with higher ability. Second, we test the relation between analysts' report readability and stock trading volume reactions. We find that trading volume reactions increase with the readability of analysts' text, consistent with theoretical models that predict that more precise information (and hence more informative signals) results in investors' initiating trades. These results support the view that the readability of analysts' reports is important to analysts and capital market participants.     

ASSET PRICING WITH IN- AND OUTFLOW CONSTRAINTS: THEORY AND EMPIRICAL EVIDENCE FROM SWEDEN

The paper analyzes asset pricing and portfolio choice when domestic investors collectively cannot hold foreign assets beyond a maximum value. We add the constraint that foreign investors cannot hold more than a fraction of the shares of domestic assets. Consistent with Swedish stock market data, both domestic and foreign investors pay premiums for investing in the other country's assets. Some empirical observations are inconsistent with the CAPM framework.     

A structural model for early exit of older men in Belgium

In this article, we propose a structural model of the retirement decision for older workers in Belgium. We model the exit paths available through the various available schemes. Our framework allows exploiting all information on possible exit paths and also better identifying preferences and constraints. Results based upon Belgian microsimulation data from 2001 for private sector workers fits rather well-observed behavior. Simulations of hypothetical reforms illustrate the potential effects of changing social security rules.     

Dynamic Spanning in the Consumption-Based Capital Asset Pricing Model

Under the assumptions of the Consumption-based Capital Asset Pricing Model (CCAPM), Pareto optimal consumption allocations are characterized by each agent's consumption process being adapted to the filtration generated by the aggregate consumption process of the economy. The wealth processes of the agents, however, are adapted to the finer filtration generated by aggregate consumption and the conditional distribution of future aggregate consumption. Therefore, in order to achieve Pareto optimal consumption allocations, a sufficiently varied set of assets must exist such that any wealth process adapted to this finer filtration can be implemented by dynamically trading in that set of assets. We provide sufficient conditions for the existence of such a set of assets based on dynamically trading contingent claims on aggregate consumption. In addition, we give sufficient conditions for the existence of equilibria in a dynamically effectively complete market in which agents are only able to trade in contingent claims on aggregate consumption, the market portfolio of firms, and a (numeraire) zero-coupon bond. We demonstrate the role of short- and long-term contingent claims on aggregate consumption for the implementation of Pareto optimal allocations in the presence of short- andlong-term risks. In addition, in the presence of personal risks, we demonstrate the role of insurance contracts.     

Crossing East-West boundaries: Knowledge sharing in intercultural business networks

Strategic business nets are becoming increasingly important in the arena of global competition. This article examines the influence of ethnic culture on knowledge sharing in different types of intercultural business nets. Knowledge sharing is essential for the functioning of business networks as it influences the cooperation and outcomes that firms are able to achieve. Our basic assumption is that the nature of the cultures involved and the type of network both influence the knowledge-sharing barriers. This is investigated on the basis of two conceptual frameworks. The first is a framework identifying different types of strategic nets and the requirements they impose for knowledge sharing. Subsequently, a culture-classification scheme based on the individualism-collectivism and the vertical-horizontal dimensions is derived. The strategic net and cultural types are then combined in an intercultural business-net framework, and the opportunities for and barriers to knowledge sharing are analysed using examples representing Asian-European and Asian-North American joint ventures and networks.     

Rise of strategic nets — New modes of value creation

This paper focuses on the type and management of intentionally created business networks called nets. Nets are extensively being used to achieve a variety of benefits over those of a single firm or market transaction. We propose that the effective management of different types of business net is dependent on their underlying value creation logic. Based on this notion a value creation framework of three generic net types - ‘current business nets’, ‘business renewal nets’, and ‘emerging new business nets’ - is suggested. We argue that they pose widely different conditions and requirements for net management. The management mechanisms of these basic net types are then identified and discussed. We contend that the proposed contingency framework captures the complexity and variety of the expanding strategic business nets in a more valid way than the extant classifications of network organizations. The paper contributes to the emerging theory of network management.
