This paper reports a new experimental test of the notion that behavior switches from risk averse to risk seeking when gains are “reflected” into the loss domain. We conduct a sequence of experiments that allows us to directly compare choices under reflected gains and losses where real and hypothetical payoffs range from several dollars to over $100. Lotteries with positive payoffs are transformed into lotteries over losses by multiplying all payoffs by –1, that is, by reflecting payoffs around zero. When we use hypothetical payments, more than half of the subjects who are risk averse for gains turn out to be risk seeking for losses. This reflection effect is diminished considerably with cash payoffs, where the modal choice pattern is to exhibit risk aversion for both gains and losses. However, we do observe a significant difference in risk attitudes between losses (where most subjects are approximately risk neutral) and gains (where most subjects are risk averse). Reflection rates are further reduced when payoffs are scaled up by a factor of 15 (for both real and hypothetical payoffs).

In the last five years, there has been an increased interest across the globe, and in the United Kingdom in particular, to define, conceptualise and measure learning gains. The concept of learning gains, briefly summarised as the improvement in knowledge, skills, work-readiness and personal development made by students during their time spent in higher education, has been hailed by some as an opportunity to measure ‘excellence’ in teaching. This chapter will review some of the common definitions and the methods employed in research on learning gains. Secondly, we will provide a critical evaluation of the computational aspects of learning gains (e.g., raw gain, normalised gain). Finally, we will critically reflect upon the lessons learnt and what is not yet known in terms of learning gains.

This article explores the value creation process from player sales in football to understand if the related capital gains correspond to significant increases in the stock value of selling companies. In addition, it aims to detect any potential drivers for higher (or slower) abnormal stock returns.

The authors analyze all the capital gains of the Italian and Portuguese listed football companies (the only ones for which, based on their annual reports, it was possible to trace the net book value for each player sold and, consequently, if any, the related capital gain) from 2012 to 2020 and use event study analysis to calculate the abnormal returns of the football companies' stocks. Moreover, the authors use a multiple linear regression model to identify the factors affecting investors' reactions and value creation process intensity.

The results show that, on average, the capital gains from player transfers in football are positive income components and produce statistically significant higher abnormal returns. In addition, the authors identified some relevant drivers related to their intensity which could guide the choices of corporate executives regarding future disposals of the multi-year performance rights of players in the roster.

This study considers only Italian and Portuguese football listed companies. It would be helpful to consider some of the companies from other countries which are also outstanding from the sports perspective, but, in practice, it was not possible due to the impossibility to trace the net book value of the single footballers sold in those clubs' public financial disclosure.

The value relevance of the capital gains from player trading activities should increase their importance, creating cascade effects on several activities generating value for football clubs (youth sector management, player scouting, technical improvement of the players). In addition, financial data show that the capital gains from player transfers are a basic income of European football clubs nowadays. Their executives consider these operations recurrent and continually search for more valuable transfers. Hence, it is reasonable to think that they (will) choose the players to sell considering both sports and financial aspects.

To the best of the authors' knowledge, this is the first study exploring the effects of capital gains from player trading activities on professional football clubs' stock value. The results obtained are even more relevant if one considers the importance these income components have in the profit formula of professional football clubs nowadays, also because of the negative repercussions caused by the recent COVID-19 pandemic.

The primary purpose of this paper is to take an in-depth look at the question of whether liberalizing trade in agriculture can generate dynamic productivity gains comparable to those in the manufacturing sector.

In contrast to the manufacturing sector that has generated firm/plant-level trade data, there is a lack of farm-level trade data that are needed for empirical measurement of dynamic productivity gains. Therefore, the authors use thought experiments to analyze the sequence of events that would occur when trade is liberalized for agriculture; delineate the expected behaviors of the actors involved in the trade and draw inferences about whether there would be dynamic productivity gains from agricultural trade.

The central finding is that there would be little dynamic gain from agricultural trade at the farm level due to the limited role of producers in shaping their international competitiveness. Yet, agricultural trade may generate dynamic gains if states or input supply corporations respond to the freer trade environment by making more investments for research and development (R&D). Further, when intraindustry prevails, there can be productivity gains at the industry level due to the transfer of resources from less to more efficient farm producers.

The findings of the paper are expected to present insights into value for researchers working in the area of agricultural trade; for agricultural trade policymakers in developing countries and for trade negotiators engaged in reforming or designing World Trade Organization (WTO)’s trade rules for agriculture.

The purpose of this paper is to investigate the welfare gains from risk sharing among African countries and regional groupings in Africa that are planning to establish monetary unions either in the short or longrun.

The paper empirically tested two hypothesis; potential welfare gains and unexploited welfare gains. It uses a utility-based measure to quantify the gains that would accrue from joining a risk sharing arrangement such as a monetary union. The regional groupings considered include the African Union (AU), the Economic Community of West Africa (ECOWAS), the Southern African Development Community (SADC) and the East African Community (EAC).

The results provide support for both hypotheses. Overall, the average potential welfare for AU, EAC, ECOWAS and SADC groups under full risk sharing are found to be 1.9, 2, 3.4 and 1.6 percent, respectively, each higher than the 1 percent estimated for the OECD countries and 0.6 percent for the 14-EU countries. The average unexploited gains are, however, even bigger for AU at 3.5 percent, ECOWAS at 8.6 percent and for SADC at 2.6 percent.

The finding of enormous potential welfare gains could partly reinforce the desire of the African countries to establish monetary unions. On the other hand, the paper provides insights to policy makers in designing policies to promote risk sharing given the finding that the unexploited welfare gains are on average still too low – implying that many African countries or groups still have very low risk sharing.

Previous studies on welfare gains and risk sharing have basically left out the African regional groupings and never related the issue of gains to the monetary union projects. Besides, previous studies focus on unexploited welfare gains at the expense of total potential welfare gains. Considering the two types, however, presents a more complete picture of total gains from joining any risk sharing arrangement such as a monetary union.

Agency theory suggests that if managers are not monitored, takeover negotiations may be contaminated by agency conflicts, which may weaken a firm's bargaining position. This paper argues that some blockholders are more effective monitors than others, and tests whether the negotiating power of a target or bidder is influenced by their respective blockholder composition. The paper aims to discuss these issues.

This paper classifies target and bidder outside blockholders as either aggressive monitors or moderate monitors, and tests whether the degrees of monitoring effectiveness influence a firm's share of the total wealth created by the takeover (a proxy for bargaining power).

This paper finds that firms that have the types of outside blockholders with a greater tendency to monitor managers elicit higher takeover gains. This suggests that negotiating power in takeovers is conditioned on the types of blockholders that monitor the target and bidder. The results support the premise that better monitoring leads to higher gains for shareholders in a takeover. In particular, the findings suggest that the greater the tendency of outside blockholders to monitor managers, the lower the level of takeover-related agency conflicts and the stronger a firm's relative bargaining power.

These findings imply that agency conflicts on either side of a takeover bid may be reduced by better monitoring, but especially among bidders.

The purpose of this paper is to examine whether the framework of Prospect Theory and Mental Accounting proposed by Grinblatt and Han (2005) can be applied to analyzing the relationship between the disposition effect and momentum in the Chinese stock market.

The paper applies the methodology proposed by Grinblatt and Han (2005).

Using firm-level data, with a sample period from January 1998 to June 2013, the authors find evidence that the momentum effect in the Chinese stock market is not driven by the disposition effect, contradicting the findings of Grinblatt and Han (2005) concerning the US stock market. The discrepancies in the findings between the Chinese and US stock markets are robust and independent of sample periods.

The findings suggest that Grinblatt and Han’s model may not be applicable to the Chinese stock market. This is possibly because of the regulatory differences between the two stock markets and cross-national variation in investor behavior; in particular, the short-selling prohibition in the Chinese stock market and greater reference point adaptation to unrealized gains/losses among Chinese compared to Americans.

This study provides evidence of the inapplicability of Grinblatt and Han’s model for the Chinese stock market, and shows the differences in the relationship between disposition effect and momentum between the Chinese and US stock markets.

In Portugal, between 1989 and 2010, capital gains from corporate shares were exempted, while gains from other instruments, like limited liability companies (LLC) equity stakes, were taxed. Inevitably, this non-neutral tax treatment originated a notorious tax arbitrage, consisting in the transformation of the legal status of a LLC into a corporation, the subsequent share sale and tax exemption. In tax litigation, many arbitration rulings were delivered, with widely divergent decisions. The purpose of this paper, using a blend of the legal research method and case analysis, is to discuss three research questions. Should the general anti-abuse clause (GAAC) be applied to this tax planning operation? Why the divergence in arbitration rulings? Is this anomalous arbitration outcome because of the wording the GAAC and its complexity or, contrarily, does it emerge from the disconnection between the set of rules governing capital gains taxation and the legislative intent that is behind such rules?

The methodology used in this paper is based on a mix of the legal research method and case analysis. In the case of legal research, a hermeneutic approach – meaning that documents, texts and their interpretation can produce important fruits to the development of the field – is a tested and fruitful approach. Besides being a hermeneutic discipline, it is an argumentative one. By exposing arguments that confirm or deny particular solutions, legal research (e.g. in criminal, business or administrative law) can influence better legislative choices by political actors. Advantages of case analysis include lessons learned from observation. The author discusses if the application of the GAAC to an arrangement that originated a tax exemption can be validated by the usual interpretative lines that doctrine sustains should be observed when a GAAC is used to void legal schemes. The pros and cons of tax arbitration are also highlighted.

The conclusion of this paper is that the GAAC is not the crux of the problem. Instead, a contradictory or, at least, disconnected relation between the expressed intent of legislators and the wording of capital gains tax clauses is, in our view, the main reason for such divergent arbitration rulings on the same issue.

The author believes that the paper is a contribution to the literature, given the global use of anti-abuse clauses and the interpretative complexities they originate. Moreover, the analysis in this paper is carried out in a legal setting where a disconnection is detectable between the expressed legislative intent and the legal drafting of personal income tax rules related to the exemption of capital gains. Studying the complexity added by this feature of the Portuguese legislation serves as a reminder of the importance of careful and well-crafted wording to achieve consistent court outcomes.

The paper has value to governments, tax authorities and tax managers, given the ever-increasing use of anti-abuse clauses in many countries, and the potential use of arbitration in similar settings.

This paper provides evidence suggesting capital gains tax affects stock returns and trading volume. The Canadian federal government budget of May 23, 1985 provided individual taxpayers with a cumulative tax exemption for capital gains, up to a lifetime limit of $500,000. The empirical results, using daily stock return and trading volume data from the Toronto Stock Exchange, show that stock prices decreased three days before the announcement of the lifetime capital gains exemption. The empirical results also show that stock trading volume increased two days and four days before the announcement and five days following the announcement. These results are consistent with the argument that the capital gains tax constrained some individual shareholders from selling appreciated shares (often called “lock‐in effect”).

Whereas motivation and coordination losses in teams have been investigated for quite some time, systematic research on performance gains in teams (often called “synergetic effects”) only emerged recently. The purpose of the present paper is to clarify the concept of process gains (or synergy) in teams, and to introduce recent findings from basic psychology that can be very valuable for the management of high performing teams.

Based on the definition of synergy as process gain during teamwork compared with a clear baseline (team potential), this review develops specific requirements for the empirical demonstration of synergetic effects in teams. Moreover, a brief history of research on process gains in teams is provided, followed by an outlook on current and future trends in this field.

Although this research is still in its pioneering days, various triggers of process gains in teams have been already derived theoretically and/or demonstrated empirically, among them social support from fellow team members, perceived indispensability for the team outcome, the development and/or selection of experts for task and team processes, use of multiple perspectives and information, team learning, and social identification processes.

Understanding the preconditions and underlying mechanisms of process gains in teams enables managers to trigger performance levels of teams that exceed what can be expected based on the individual team members' capabilities alone. Moreover, the estimation of a team's potential provides a helpful standard for the assessment of the ongoing team performance.

Process gains in teams and related laboratory research have been largely neglected in the managerial literature so far. This paper and the current special issue are among the first to introduce a clear definition of process gains in teams, and to suggest concrete trigger factors of synergetic effects in teams based on systematic research.
