Uncertainty and Learning in Stochastic Macro Models

Limits on information have deep economic impact and affect the conduct of economic policy. In the present paper we explore the effect of substantive uncertainty in a macro model, from both an analytical and methodological point of view. Agents are boundedly rational and make their forecasts according to different techniques and try to learn the values of the various parameters. In this context, a Markov regime switching rule, a VAR system, and recursive least square are considered and compared. As a result, we obtain a model which is mostly keynesian in nature that can be compared with the new neoclassical synthesis models. Simulations are carried out and show the possible appearence of endogenous and persistent fluctuations.     

Short Selling and the Weekend Effect in Nasdaq Stock Returns

We examine daily short selling of Nasdaq stocks to explore whether speculative short selling causes a significant portion of the weekend effect in returns. We identify a weekend effect in speculative short selling whereby it constitutes a larger percentage of trading volume on Mondays versus Fridays. We find an opposite effect in dealer short selling, consistent with market makers adding liquidity and stability. Our main finding is that speculative short selling does not explain an economically meaningful portion of the weekend effect in returns, even among the firms most that are most actively shorted. This finding contradicts some prior studies.     

Implementation of responsible Procurement Management: An Institutional Perspective

The role of the institutional context in the pattern of the implementation of responsible procurement management (RPM) has been object of very limited previous research, although it has been found that it affects the approach to both CSR and supply chain management. The article presents the results of an in‐depth comparative study drawing on 47 interviews with managers of 13 companies in Italy and Germany, which have been previously related to different national institutional settings. The analysis demonstrates that the perception of factors influencing RPM implementation differs between Italian and German companies, and suggests that the institutional context affects not only the overall CSR behavior of the company, but also its institutionalization into a specific function. Results show that the institutional context mainly determines the boundaries within which practitioners are able to operate, whereas the ability to effectively bring about changes in their activity mainly depends upon organizational environment.

The Listing, Size, and Value of Equity Warrants

This note examines whether listing on a major exchange raises the value of warrants. Such an increase is plausible, given the generally small size of warrant issues and the enhanced liquidity that organized trading can provide. Using Black-Scholes pricing techniques, the study concludes that listing has a positive and substantial impact on the per unit price of seasoned warrant issues. Moreover, the tests indicate that the impact is so consistently large for small warrant issues that firms should consider listing these securities at the time of issuance.     

AN ANALYSIS OF THE WALL STREET JOURNAL'S COVERAGE OF CORPORATE NEWS AND THE RESEARCH DESIGN OF EVENT STUDIES

The typical event study of corporate news restricts its sample of announcements to events reported in the Wall Street Journal (WSJ) and listed in the WSJ Index. In this paper we examine whether such samples are representative of the events omitted from the WSJ. Focusing on convertible calls in the 1980s, we analyze possible differences between a sample based only on the WSJ Index and a larger but similarly constructed sample of calls reported in the Dow Jones News Service but not in the WSJ Index. Numerous parametric and nonparametric tests reveal no significant cross-sample divergences in key attributes of the calling firms and called bonds, or in the distributions of risk-adjusted returns around announcements. This evidence suggests that WSJ-based samples for other corporate news items can be representative of cases not covered by the WSJ. Further, the evidence indicates that the results of event studies using WSJ-based samples may support inferences about events not reported in the newspaper.

Exploring different views of exchange rate regime choice

The empirical distinction between de facto and de jure exchange rate regimes raises a number of interesting questions. Which factors may induce a de facto peg? Why do countries enforce a peg but do not announce it? Why do countries “break their promises”? We show that a stable socio-political environment and an efficient political decision-making process are a necessary prerequisite for choosing a peg and sticking to it, challenging the view that sees the exchange rate as a commitment device. Policymakers seem rather concerned with regime sustainability in the face of adverse economic and socio-political fundamentals.     

Bank shareholding and lending: Complementarity or substitution? Some evidence from a panel of large Italian firms

The paper studies the motivations behind banks’ shareholding of non-financial firms using a panel of large Italian companies in the period 1994–2000. Empirical evidence shows that banks are shareholders of companies that are less profitable, have experienced slower growth, are more indebted, are endowed with collateral and have hard time to repay their debt out of current income. Banks are more likely to hold shares in companies they lend to. Overall the evidence suggests that there is complementarity between bank equity holding and lending. A plausible explanation is the shareholder–debtholder conflict, the evidence is weakly compatible with governance and information hypotheses.

Food for Kids: How Children Influence their Parents Purchasing Decisions

During the last decades, sociological changes have modified the role of children within families: participatory models have become more widespread, to the detriment of more authoritative ones: this change has had consequences also in reference to families’ purchases. In scientific literature some scholars have shown that this influence is real, and marketers try to take advantage of this through a communication style that attempts to “teach” children how to pester their parents: this is the so-called nag factor. To understand which are the parental attitudes toward kids’ food products, a questionnaire has been administered in schools (nursery and primary) to a random sample of parents, representative of a larger sample of kids (200 in all). Findings showed that pestering is a real attitude, in particular among the littlest children. Moreover, these findings reflect in part the reality described by marketing literature: children influence the purchasing decisions of their parents, but this influence decreases when mothers and fathers are more aware of the importance of a quality-based diet.
