The effect of a switch of management company on pension plan fees
(Routledge, 2021) Abinzano Guillén, María Isabel; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas
The impact of a switch of management company on pension plan fees is analysed by comparing the effects on employer-sponsored versus individual defined-contribution private pension plans in Spain. This framework is ideal because the two types differ significantly both in plan governance structure and consequently in the degree of bargaining power held by the decision-maker. In addition, intense bank restructuring, which has greatly modified the Spanish pension plan map, provides an interesting analytical context for the identification of causal links, because it is a scenario that features shocks exogenous to the relationship under analysis. The results show that a switch of management company significantly reduces management fees for employer-sponsored plans when the management change is not due to the bank restructuring process, on the contrary a switch of management company increases fees for individual pension plans.

Does default probability matter in Latin American emerging markets?
(Taylor & Francis, 2013) Abinzano Guillén, María Isabel; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Gestión de Empresas; Enpresen Kudeaketa
We analyse the impact of default probability in four leading Latin American stock markets (Argentina, Brazil, Chile and Mexico). We find no positive default risk premium except in the case of Brazil, and in fact find a negative risk premium for Argentina and Mexico. The latter effect tends to fade when the analysis accounts for size and BTM market variables. Although we find no size effect in any of the markets considered, the BTM effect is very strong in all of them, and our results reveal a consistent relationship, analogous to that found in more developed markets, between default probability and the size and book-to-market variables.

The role of investor type in the fee structures of pension plans
(Springer, 2016) Abinzano Guillén, María Isabel; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Gestión de Empresas; Enpresen Kudeaketa
We examine the role of the investor type in the fee structure of pension plans. Our examination uses a data set of employer-sponsored and individual private pension funds in Spain. We find different determinants of the fees between these two pension plans. We find evidence of market penetration strategies in individual plans but none in employer-sponsored plans. In these plans, the fees are negatively related to their financial groups’ market share, whereas in individual plans this relation is negative for management fees but positive for custodian fees. Further, except in the case of custodian fees in individual plans, we find that all fees diminish when the custodian and management firms belong to different financial groups.

The role of small bettors in price formation in betting exchanges
(Routledge, 2020) Abinzano Guillén, María Isabel; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Institute for Advanced Research in Business and Economics - INARBE
The presence of small bettors in betting exchanges generates mispricing, which can lead to exploitation by informed traders or result in permanent price deviations. This paper shows that mispricing from this source is also dependent upon variables of established relevance such as tournament round, the level of attention to the event, the volume of the betting, and bet type, further confirming these findings by means of cumulative accuracy profile (CAP) curves. It also offers evidence of the relevant role played by the type of device used to place the bet, whereby higher mispricing is observed in live bets placed via a mobile device, which appears to be associated with impulsive betting. This last finding could have practical implications for the regulation of the use of mobile devices to access gambling platforms.

Behavioral biases never walk alone: an empirical analysis of the effect of overconfidence on probabilities
(SAGE, 2014) Abinzano Guillén, María Isabel; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Gestión de Empresas; Enpresen Kudeaketa
This paper presents evidence of the impact of overconfidence bias in asset prices drawn from a study based on data from tennis betting exchanges. A series of betting strategies in tournaments with a clear-cut favourite are shown to yield significant economic returns. The impact of overconfidence bias on betting odds increases with trading volume, media coverage, and levels of disagreement between overconfident and Cumulative Prospect Theory bettors. Just as in traditional financial markets, arbitrage limits are shown to be a necessary condition for the impact of behavioural biases on prices.

Game, set and match: the favorite long-shot bias in tennis betting exchanges
(Taylor & Francis, 2016) Abinzano Guillén, María Isabel; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Gestión de Empresas; Enpresen Kudeaketa
We test for the existence of Favorite-Longshot Bias (FLB) in tennis betting exchanges. Despite these being order-driven markets, with no direct participation from bookmakers, we have found very similar results to those obtained by Lahvička (2014) for bookmakers’ betting markets: the bias is stronger in matches between lower ranked players, in later round matches and in high profile tournaments. This suggests that bookmakers’ adjustments to respond to informed betting are not the main driver of FLB. The varying magnitude of the bias across different types of event in the main market also weakens arguments linking FLB to gamblers’ risk preferences, and suggests the need to consider the microstructure features of the market together with the cognitive biases highlighted in the behavioral finance literature.

Is default risk the hidden factor in momentum returns? Some empirical results
(Wiley, 2014) Abinzano Guillén, María Isabel; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Gestión de Empresas; Enpresen Kudeaketa
This paper analyzes the role of default risk in the momentum effect focusing on data from four developed European stock markets (France, Germany, Spain and the United Kingdom). Using a market-based measure of default risk, we show that it is not the hidden factor behind this effect. While the loser portfolio is characterized by high default risk, small size, high BTM and illiquidity, characterization of the winner portfolio is somewhat more complex. Given that the momentum strategy is the return differential between the winners and the losers, factors such as the stock market cycle or the evolution of momentum portfolios against their reference point make momentum profits difficult to forecast.

Bad company. The indirect effect of differences in corporate governance in the pension plan industry
(Elsevier, 2017) Abinzano Guillén, María Isabel; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Institute for Advanced Research in Business and Economics - INARBE
This paper analyses the role played by pension plan governance structure and how it impacts on plan fees and plan performance. The results clearly show that fees decrease significantly and performance improves when pension plan governance structures permit full alignment of interests and allow greater capacity for the decision-makers to monitor and discipline the managers. It is also observed that companies managing both employee and individual funds, tend to exploit differences in the internal corporate governance mechanisms of each type of plan in order to nurture employer-sponsored plans at the expense of individual plans. These results suggest that internal corporate governance mechanisms allowing closer alignment with the interests of participants would be preferable to focusing exclusively on setting the minimum proportion of independent directors.

Hidden power of trading activity: the FLB in tennis betting exchanges
(SAGE Publications, 2017) Abinzano Guillén, María Isabel; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Institute for Advanced Research in Business and Economics - INARBE
This paper examines the impact of trading activity on the Favourite-Longshot Bias (FLB) in tennis Betting Exchanges, using direct measures such as betting volume, average bet and standard deviation of the odds. According to predictions based on Disagreement Models, odds mispricing is positively associated with trading volume but negatively associated with the presence of institutional bettors. The FLB is also positively related to the degree of uncertainty in the market. The existence of two simultaneous markets (a “main” and an “alternative” market) in this specific sports-betting environment has enabled us to observe that the relative amount of attention given to the favourite versus that given to the long shot is positively associated with the FLB. Finally, information is more rapidly incorporated into the odds in the market that receives more attention from bettors, an effect that is intensified by the arbitrage and hedging that occurs between the two markets.
