When is escalation of commitment unstoppable in group settings? An iterative economic modeling approach to unveil the dark side of group decision-making

Escalation of commitment (EOC) has been usually studied from a psychological lens, and only recently have scholars approached EOC from an economic perspective. We contribute to this by focusing on iterative decision-making in group settings with a game theory approach. We study how the group members' strategic interaction may result in continuing failing courses of action. Drawing on the Byzantine generals' problem, our model considers an iterative decision-making process where committee participants vote based on private information to escalate or not. Our article demonstrates that if decision-makers reset their beliefs based on the committee's previous decision, then EOC becomes perpetual.     

Be bad but (still) look good: Can controversial industries enhance corporate reputation through CSR initiatives?

Even though the link between perceived corporate social responsibility fit (PCSR‐fit) and corporate reputation has received much attention from scholars, this tradition has ignored that the underpinnings of this association vary depending on the particular characteristics of each industry under study. To delve into this matter, we investigate in the increasingly relevant context of controversial industries (CIs) how PCSR‐fit could enhance corporate reputation and which are the mediating mechanisms of this association. Our academic contribution is twofold. First, we find that controversial sectors indeed can increase corporate reputation through CSR activities. However, we find that to achieve this goal, the nature of PCSR‐fit should be different than what extant literature indicates, because companies in these settings should directly focus on avoiding or reducing their inherent controversial harm or impact. Second, we evidence that “CSR initiatives' legitimacy” and “situational skepticism” mediate the PCSR‐fit and corporate reputation relationship in CIs. Therefore, we further unravel the underpinnings of this association to advance what we know on the matter and aid practitioners in this particular context.     

A profitable trading and risk management strategy despite transaction costs

We present a new profitable trading and risk management strategy with transaction cost for an adaptive equally weighted portfolio. Moreover, we implement a rule-based expert system for the daily financial decision-making process using the power of spectral analysis. We use several key components such as principal component analysis, partitioning, memory in stock markets, percentile for relative standing, the first four normalized central moments, learning algorithm, and switching among several investment positions consisting of short stock market, long stock market and money market with real risk-free rates. We find that it is possible to beat the proxy for the equity market without short selling for 168 S&P 500-listed stocks during the 1998–2008 period and 213 Russell 2000-listed stocks during the 1995–2007 period. Our Monte Carlo simulation for both the various set of stocks and the interval of time confirms our findings.     

Does it really pay to be good,everywhere? A first step to understand the corporate social and financial performance link in Latin American controversial industries

Most research studying the corporate social performance (CSP)–corporate financial performance (CFP) link has utilized developed country samples. Also, this literature has generally focused on a wide variety of industries, ignoring the fact that certain sectors – such as controversial industries – have graver social and environmental issues. Hence, a gap exists in this tradition when it comes to emerging markets and controversial industries. This paper attempts to fill this void by providing preliminary evidence and insight on the matter. Based on an exploration in six Latin American countries and five controversial industries, we find a negative bidirectional association (or a non‐significant one at best) between CSP and CFP. These results tend to contradict the mainstream conclusion of a positive bidirectional link, suggesting that institutional and market‐level forces play a major role in shaping this relationship.     

State ownership,political ideology,and firm performance around the world

It is often taken as a stylized fact that state ownership harms the financial performance of firms. Yet we show that this relationship varies greatly across national contexts. We argue that the political ideology of the government, both independently and in conjunction with political institutions (state capacity and political constraint), affects this relationship. We test our hypotheses using meta-analytical techniques on an international sample spanning 53 years and 131 countries. Our research sheds further light on the state ownership – firm performance relationship by highlighting the role of the political ideology of the government, and its interactions with political institutions.     

COMPETITIVE MARKET BEHAVIOR: CONVERGENCE AND ASYMMETRY IN THE EXPERIMENTAL DOUBLE AUCTION

We conducted a large number of controlled continuous double auction experiments to reproduce and stress-test the phenomenon of convergence to competitive equilibrium under private information with decentralized trading feedback. Our main finding is that across a total of 104 markets (involving over 1,700 subjects), convergence occurs after a handful of trading periods. Initially, however, there is an inherent asymmetry that favors buyers, typically resulting in prices below equilibrium levels. Analysis of over 80,000 observations of individual bids and asks helps identify empirical ingredients contributing to the observed phenomena including higher levels of aggressiveness initially among buyers than sellers.     

Mathematical Needs and Economic Interpretations

This paper discusses why the disconnection between formal structuresand theoretical content in economic model building can leadto undesirable consequences. By contrast, linking formal andverbal contents by means of coherent and relevant interpretationsis worth the effort: it is a relatively simple way of helpingto improve mathematical economic theorization. By way of illustration,the interpretation that Arrow and Debreu put on the inclusionof free goods in their proof of existence of general equilibriumis also discussed.
