Un mercado implica, de manera general, un conjunto de interacciones relativamente complejas entre agentes a lo largo del tiempo. En consecuencia, recientes investigaciones en el campo de las finanzas intentan integrar el comportamiento estratégico de los agentes en los modelos existentes. Dos importantes líneas de investigación en las que la incidencia del comportamiento estratégico ha sido ampliamente explotado son la valoración de la deuda de la empresa y la microestructura del mercado. En el segundo capítulo se desarrolla un eventual modelo de valoración para bonos de cupón cero en mora. Con el objetivo de destacar el papel del vencimiento y de la colocación de la demanda del prestatario en la jerarquía de la deuda de una empresa, tomaremos el caso de una empresa que emita dos bonos con vencimiento y prioridad distintos. Este modelo nos permite analizar las implicaciones, tanto de la renegociación de la deuda como de la estructura del capital de la empresa en el precio de los bonos. Veremos que la renegociación conlleva un cambio significativo en el precio de los bonos y que su efecto se dispersa a través de varios canales: incrementando el valor de la empresa, reasignando pagos y evitando liquidaciones costosas. Asimismo, la presencia de dos acreedores tiene implicaciones cualitativamente diferentes en precio, y a la vez pone énfasis en la importancia de los contratos de bonos y la renegociación de la totalidad de la deuda. En el tercer capítulo se desarrolla el modelo de tráfico de información privilegiada en el que los agentes tienen información privada sobre el valor de liquidación o sobre la oferta y actúan de modo estratégico para maximizar sus beneficios. El operador de ofertas informado tiene un doble papel en la creación de mercados y en la revelación de información. Este operador, no sólo revela parte de la información que posee, sino que también induce a otros operadores a revelar una mayor parte de su información privada. La presencia de varios tipos de información reduce la liquidez del mercado e induce a la no-monotonicidad de los indicadores de mercado respecto a la variación del valor de liquidación. El cuarto capítulo aborda temas de microestructura, esta vez en relación con la tributación con problemas de incertidumbre. Se desarrolla un modelo en el que consideramos las implicaciones del informe fiscal en los beneficios por tráfico de información privilegiada. Se modela la interacción entre la empresa y la agencia de auditoría fiscal como relación principal-agente sin compromiso. Por otro lado, los mercados financiero se modelan de acuerdo con Kyle (1985), con la diferencia de que el creador de mercados establecerá un precio condicionado por dos factores el flujo total de pedidos y el informe fiscal recibido por la agencia de auditoría fiscal. Modelar la interacción entre la agencia tributaria y la empresa nos permite endogenizar el factor público. Nuestro modelo apunta a que los efectos que producen las interacciones entre la empresa y la agencia de auditoría fiscal en el comportamiento del creador de mercados y el poseedor de información privilegiada son significativos. Así pues, existen varios canales a través de los cuales el informe fiscal influye en los beneficios de quien posee información privilegiada. El informe fiscal afecta al valor de liquidación de la empresa que opera en mercados financieros de dos modos: mediante los impuestos directos pagados honradamente y mediante los esfuerzos de auditoría (lo que en nuestro modelo depende del informe fiscal). A su vez, el valor de liquidación afecta a la demanda y, consecuentemente, al flujo de pedidos. Finalmente, puesto que el creador de mercados utiliza los informes fiscales como factor esto afecta directamente a los precios establecidos por el creador de mercados y, consecuentemente, a toda la actuación del mercado. / A market typically involves a relatively complex set of interactions between agents over time. Consequently, recent research in finance tries to integrate strategic behaviour of the agents in the existing models. Two important directions of research where the incidence of strategic behavior has been widely exploited are valuation of corporate debt and market microstructure. In the second chapter we develop a contingent valuation model for zero-coupon bonds with default. In order to emphasize the role of maturity time and place of the lender's claim in the hierarchy of debt of a firm, we consider a firm that issues two bonds with different maturities and different seniorage. The model allows us to analyze the implications of both debt renegotiation and capital structure of a firm on the prices of bonds. We obtain that renegotiation brings about a significant change in the bond prices and that the effect is dispersed through different channels: increasing the value of the firm, reallocating payments, and avoiding costly liquidation. Moreover, the presence of two creditors leads to qualitatively different implications for pricing, while emphasizing the importance of bond covenants and renegotiation of the entire debt.In the third chapter we develop a model of insider trading where agents have private information either about liquidation value or about supply and behave strategically to maximize their profits. The supply informed trader plays a dual role in market making and in information revelation. This trader not only reveals a part of the information he owns, but he also induces the other traders to reveal more of their private information. The presence of different types of information decreases market liquidity and induces non-monotonicity of the market indicators with respect to the variance of liquidation value.The fourth chapter is concerned also with microstructure issues, this time in connection with a taxation under uncertainty problem. We develop a model in which we consider the implications of tax report on the profits from insider trading. We model the interaction between the firm and the tax auditing agency as a principal-agent relationship with no commitment. On the other hand, the financial markets are modelled as in Kyle (1985), with the difference that the market maker will set the price conditional on two signals: the total order flow and the tax report received by the tax auditing agency. Modelling the interaction between the tax agency and the firm allows us actually to endogenize the public signal. Our model points out that the effects the interactions between the firm and the tax auditing agency have both on market maker's and insider's behaviour are significant. Thus, there exist several channels through which the tax report affects the profits of the insider. The tax report affects the liquidation value of the firm traded in financial markets in two ways: through the direct taxes honestly paid and through the auditing effort (which in our model is contingent on the tax report). On its turn, the liquidation value affects the demand and therefore the order flow. Finally, since the market maker uses the tax report as a signal, it directly affects the pricing rule set by the market maker, and therefore, all the market performance.

The contribution of small firms towards the creation of economic value in a country’s Gross Domestic Product, employment and innovation is widely acknowledged. Relatively little is known on how small firms are adopting IT strategically to acheive business-IT alignment and how alignment changes over time. This study examines from a dynamic perspective IT adoption actions undertaken by owner-managers, in relation to business-IT alignment in small firms in the island state of Malta. To attain its research objectives, the methodological stance adopted in this research study is that of grounded theory. Moving away from a deductive approach, this study embraces a constructivist approach using a combination of inductive and abductive thought. No fewer than thirty-one in-depth interviews are conducted with owner-managers to observe alignment patterns of IT adoption behaviour in their respective small firms operating in Malta and employing up to 49 employees. Four business-IT alignment equilibrium states are identified, serving as markers to map out the common IT alignment paths that each firm pursued, not necessarily in linear form, during their operational years. A substantive model, which identifies four distinct IT alignment patterns, denotes each common path that a group of firms took in their movement from one alignment equilibrium state to another, throughout their life-cycle stages. This study has substantive application and comprises several implications for the development of IT adoption behaviour when small firms endeavour to strategically align business with IT. It provides policy-makers, academic researchers and small firms’ owner-managers with a theoretical framework that can provide them with factors that can predict the kind of alignment patterns that are likely to occur. Findings indicate that the quality of IT related technological solutions that are taken up by each small firm are reliant on the owner-manager’s characteristics that focus mainly on the knowledge of internal IT expertise and the project management capabilities to manage IT outsourcers. Given that few studies have been conducted to study and establish patterns of IT alignment in small firms, this research provides an important contribution to knowledge and to the existing academic literature.

This paper is focused on the effect board gender diversity has on firm risk-taking behaviour within the domain of mergers and acquisitions (M&A). As existing literature has produced mixed findings concerning board effectiveness in the corporate context, it is suggested that external contingencies might have an impact on the influence of female board representativeness. In response, this study examines the impact of board gender diversity on the degree of acquisitiveness by taking a crosscultural perspective. Building on social identity theory, this paper predicts that female representativeness at the board level is negatively associated with a firm’s acquisitiveness. Additionally, this study theorizes and empirically tests the moderating effect of culture in terms of gender egalitarianism and uncertainty avoidance. The panel data used in this analysis consists of 111 Global 500 firms from 17 different countries, covering the period 2012 - 2016. Results in this paper support the notion that board gender diversity is negatively associated with acquisitiveness and that culture in terms of gender egalitarianism has a weakening effect on this relationship. Moreover, this paper contributes to existing research by offering new insights onto the role culture plays in the relationship between board gender diversity and firm risk-taking behaviour and, as a result, helps to reconcile mixed findings of previous literature focused on this topic.

One of the main concerns with the introduction of competition in the power sector is the strategic behaviour of market participants. Computable models of strategic behaviour are becoming increasingly important to understand the complexities of competition. Such models can help analyze market designs and regulatory policies. In this thesis, further developments on the modelling and analysis of strategic behaviour in electricity markets are presented. This thesis work has been conducted along three research lines. <br /><br /> In the first research line, an oligopolistic model of a joint energy and spinning reserve market is formulated to analyze imperfect competition. Strategic behaviour is introduced by means of conjectured functions. With this integrated formulation for imperfect competition, the opportunity cost between generation and spinning reserve has been analytically derived. Besides, inter-temporal and energy constraints, and financial transmission rights are taken into account. Under such considerations, competition in electricity markets is modelled with more realism. The oligopolistic model is formulated as an equilibrium problem in terms of complementarity conditions. <br /><br /> In the second research line, a methodology to screen and mitigate the potential exacerbation of market power due to the ownership of financial transmission rights is presented. Hedging position ratios are computed to quantify the hedging level of financial transmission rights. They are based on the actual impact that each participant has in the energy market, and on the potential impact that it would have with the ownership of financial transmission rights. Thus, hedging position ratios are used to identify the potential gambling positions from the transmission rights bidders, and, therefore, used to prioritize critical positions in the auction for transmission rights. <br ><br /> In the last research line, alternative equilibrium models of markets for financial transmission rights are formulated. The proposed equilibrium framework is more natural and flexible for modelling markets than the classic cost-minimization markets. Different markets for financial transmission rights are modelled, namely: i) forwards, ii) options, and iii) joint forwards and options. Moreover, one-period, multi-period and multi-round markets for forwards are derived. These equilibrium models are proposed to analyze the bidding strategies of market participants. The potential impact of bidders on congestion prices is modelled by means of conjectured transmission price functions.

Although the contribution of the small enterprise to a nation’s economy, job creation and innovation is well known, comparatively little is understood on how small firms behave strategically and how the more common patterns of strategic behaviour relate to different levels of organizational performance. The following thesis aims at mapping out the strategic behaviour of small firms in the small island state of Malta, and in relating the evident patterns of strategic behaviour to the performances of these firms. The thesis follows on the logic of understanding strategy as a dynamic phenomenon, one that can be viewed as pathways between identifiable life cycle states. It also views strategy as behaviour, part deliberate and part emergent, thus allowing for the inclusion of both external influences and internal decision making. To be able to achieve this dynamic viewpoint of strategy a particular research methodology had to be deployed, observing both the context and the consequences to a firm’s strategic actions, as well as the very actions and interactions themselves. A Grounded Theory method of enquiry was adopted for this purpose as it is ideal for observing patterns, the very theme of this thesis. The research in question has focused on small firms with up to 49 full time employees, in line with the E.U.’s definition of both micro and small firms, and in a broad range of industries in Malta. Results confirmed the predominance of five trajectories, or pathways, of small business strategic behaviour, each passing through a sequence of distinct life cycle states. For each pathway a unique performance situation was observed, resulting from the dynamic coalignment of the owner-manager’s entrepreneurial philosophy, the competitive behaviour adopted by the firm, and the competitive environment to the firm. Understanding which strategic pathway a small firm belongs to allows for a comprehensive insight into the firm’s competitive behaviour, and a prediction of the consequences to that behaviour. The audience to the research consists of government entities involved in policy construction, small firm owners and managers, and the academic community involved in research and policy design.

The aim of this paper is to gain a greater understanding of the meaning-making process behind Finland and Sweden’s decision to join NATO in 2022, and by so, deviate from their long-standing tradition of military non-alignment. Instead of solely pointing to the Russian invasion of Ukraine as the official reason for NATO membership this paper suggests that the concept of strategic culture can provide one with a greater understanding of their decision to join NATO. Resulting in the question: How can the concept of strategic culture help us understand the decision by Sweden and Finland to apply for NATO membership in 2022, despite their longstanding tradition of non-military alignment? With the concept of strategic culture, the analytical framework argues that the decision-making in Finland and Sweden was shaped by historical experiences that in turn influenced their strategic culture, which worked as a shaping context for their respective strategic behaviour. This is done through an entanglement analysis, a close reading and interpretation of the empirical material such as books, peer-reviewed articles, statements, government reports, and speeches, to demonstrate if the decision to join NATO followed Finland and Sweden’s typical strategic behaviour. This paper argues that the decision to join NATO did not represent a shift in the two state’s respective behaviour, instead the decision was in line with the strategic behaviour the states have followed since the end of the Cold War. Hence, the decision to join NATO demonstrates a sign of continuity rather than a historical shift in their foreign and security policy.

Over the last couple of decades or so, comparative public law scholars have been reporting a dramatic increase in the power and influence of judicial institutions worldwide. One obvious effect of this “judicialization of politics” is to highlight legitimacy concerns associated with the exercise of judicial power. Indeed, how do courts attain and retain their legitimacy particularly in the context of their increasing political relevance? To answer this question I develop a novel theory of strategic legitimacy cultivation. The theory is developed through an application of the institutionalist branch of the rational choice theory which suggests that institutional structures, rules, and imperatives provide behavioural incentives and disincentives for relevant actors who respond by acting strategically in order to attain favourable outcomes. The theory shows that courts cultivate legitimacy by exhibiting strategic sensitivities to factors operating in the external, political environment. In particular, legitimacy cultivation requires courts to devise decisions that are sensitive to the state of public opinion, that avoid overt clashes and entanglements with key political actors, that do not overextend the outreach of judicial activism, and that employ politically sensitive jurisprudence. The theory is tested in the context of the Supreme Court of Canada through a mixed-method research design that combines a quantitative analysis of a large number of cases, case-study approaches, and cross-policy comparisons. One of the central findings of the dissertation is that understanding judicial institutions and judicial policymaking influence requires taking close accounts of external contexts within which courts operate.
