Momentum,market states and investor behavior

This paper shows that the momentum effect appears in the wake of both up-market and down-market states in the Spanish stock market, although in the first of these cases it is followed by return reversal. This evidence, which contradicts the predictions of Cooper et al. (2004), provides the rationale for taking into account the disposition effect among the possible explanatory factors behind the momentum effect in a behavioral theory context.      

A new axiomatization of the Banzhaf semivalue

A new characterization of the Banzhaf semivalue on the domain of monotonic simple games is given. We use the well-known valuation and dummy axioms plus two additional properties. The first one simply requires that the power-index be bigger for those players belonging to more winning coalitions. The second one is the proportionality axiom introduced by Owen in (1982) which is suitable for those simple games that represent an indirect voting process.     

Going short‐term or long‐term? CEO stock options and temporal orientation in the presence of slack

Research summary: We draw on behavioral agency theory to explain how decision heuristics associated with CEO stock options interact with firm slack to shape the CEO's preference for short‐ or long‐term strategies (temporal orientation). Our findings suggest CEO current option wealth substitutes for the influence of slack resources in encouraging a long‐term orientation, while prospective option wealth enhances the positive effect of slack on temporal orientation. Our theory offers explanations for non‐findings in previous analysis of the relationship between CEO equity based pay and temporal orientation and provides the insights that CEO incentives created by stock options (1) enhance the effect of available slack upon temporal orientation and (2) can both incentivize and de‐incentivize destructive short‐termism, depending upon the values of current and prospective option wealth. Managerial summary: We explore how compensation design can play a role in affecting the CEO's preference for short‐ or long‐term strategic projects. When the CEOs have accumulated option wealth, they are more likely to invest in the long term. Yet when they have a large number of recently granted options with the potential to generate significant wealth in the event of successful risk taking, the CEO is more likely to prefer the short term in order to achieve personal wealth gains more quickly. The more liquid assets the firm holds, the weaker both of the aforementioned effects. An implication for boards is that they should anticipate CEO short‐termism if the CEO has been granted new options, underlining the potential negative consequences of option compensation.

Disruptive technology adoption,particularities of clustered firms

ABSTRACT

This article explores to what extent the internal attributes of a clustered firm influence its capacity to adopt disruptive innovations. A multidimensional approach to the absorptive capacity (ACAP) model is used to distinguish between potential (acquisition and assimilation domains) and realized (transformation and exploitation domains) internal firm capabilities. Our evidence comes from an empirical analysis of the population of firms belonging to the Spanish ceramic tile cluster which have adopted a disruptive innovation – the so-called digital printing technology – on a massive scale. The econometric estimations suggest the relevance of the Exploitation dimension of ACAP for early adoption of a new technology. In contrast, the other dimensions do not seem to play a decisive role when it comes to adopting one novelty earlier than others. In conclusion, and contrary to what was expected for non-clustered firms, the results revealed an uneven effect of the potential and realized domains of ACAP of clustered firms regarding the rate of adoption of distant technologies.     

THE REGULATION OF MORTGAGE SERVICING: LESSONS FROM THE FINANCIAL CRISIS

Pivotal litigation against the largest subprime mortgage servicer in the United States provides lessons about the appropriate regulation of mortgage servicing and adds to research about the causes of the financial crisis. Mortgage servicing is essential to the functioning of the financial system so servicers must be held to a high standard. The litigation revealed egregious practices but was settled quickly for a nominal amount and provided the servicer a very broad release of liability, allowing it to expand without correcting serious problems, and created significant wealth gains for the parent firm. Regulatory authority should not be split between agencies. (JEL G28, G21, K40)     

Oligopolistic equilibrium and financial constraints

We model a dynamic duopoly in which firms can potentially drive their rivals from the market. For some parameter values, the Cournot equilibrium outcome cannot be sustained in an infinitely repeated setting. In those cases, there is a Markov perfect equilibrium in mixed strategies in which one firm, eventually, will exit the market with probability one. Producer surplus in the maximum collusive outcome is greater under bankruptcy consideration, because the outcome that maximizes joint profits is skewed in favor of the more efficient firm. Consumer surplus and social welfare also increase in many cases, although those effects are generally ambiguous.     

An ethical defense of cryptocurrencies

The growing importance of the cryptocurrency phenomenon has raised concerns about the ethical implications of a hypothetical widespread use of these new forms of digital money. In this paper, we undertake an ethical assessment of cryptocurrencies drawing upon two specific ethical theories: private property ethics and utilitarianism. Particularly, we focus on three distinctive aspects. First, we examine the advantages and disadvantages of cryptocurrencies vis-à-vis central bank fiat money. Second, we analyze cryptocurrencies as facilitators of tax evasion and the ethical implications arising therefrom. Finally, we explore the use of cryptocurrencies for nefarious consumption. We conclude that, were cryptocurrencies to become widespread media of exchange, governments capacity to undertake monetary, fiscal, and drug policy would be undermined. We argue that this would be an ethically desirable outcome from both a private-property-rights and a utilitarian perspective since it would force governments to reduce their size and scope in these three areas.     

Do the ecoinnovation and ecodesign strategies generate value added in munificent environments?

Within innovation strategies, ecodesign and ecoinnovation are becoming very relevant in recent years as they seek to reduce the environmental impact of both products and production processes by using new technologies and ways of working that contribute to sustainable development and at the same time help to promote the competitiveness of companies. In this framework, the objective of this paper is to analyze the impact that the strategies of environmental innovation in products and processes have on the profitability and the market value of the companies, considering the moderating role that the munificence of the industry has in this relationship. Using the generalized method of moments, the results obtained from a sample of 6,454 international companies during the period 2002–2017 show that although environmental innovation strategies do not entail higher returns, they are well valued by the capital market. This was especially true in environments with greater economic growth and availability of resources, that is, in munificent environments.     

Does Teacher Subject Knowledge Contribute to Student Academic Performance in Developing and Least Developed Countries?

Little is known about the causal impact of teacher knowledge on student performance. In this research paper we intend to approach the potential causal effect (i.e. going beyond correlation) of sixth grade teachers’ knowledge on their students’ academic achievement for three Sub-Saharan African countries. To achieve this, we have used the heterogeneity of teachers’ subject knowledge and students’ correspondent academic achievement within-student between-subjects using student fixed effects. Concretely, our work is based on previous research by Bietenbeck, Piopiunik and Wiederhold. Compared to them, we do not use countries that lack representative information after keeping only those students taught by the same teacher for the subjects under analysis. This enables us to obtain more reliable results on this issue. Our results indicate that teacher subject knowledge in reading and mathematics does not have a significant influence on student academic achievement in these subjects for the countries under scrutiny. Many robustness checks have corroborated this conclusion, which contrasts with the positive effect found by Bietenbeck, Piopiunik and Wiederhold.
