The implied volatility surface is the collection of volatilities implied by option contracts for different strike prices and time-to-maturity. We study factor models to capture the dynamics of this three-dimensional implied volatility surface. Three model types are considered to examine desirable features for representing the surface and its dynamics: a general dynamic factor model, restricted factor models designed to capture the key features of the surface along the moneyness and maturity dimensions, and in-between spline-based methods. Key findings are that: (i) the restricted and spline-based models are both rejected against the general dynamic factor model, (ii) the factors driving the surface are highly persistent, and (iii) for the restricted models option Δ is preferred over the more often used strike relative to spot price as measure for moneyness.

This paper explored the relationship between the embeddedness of a firm’s managerial values and corporate financial performance in Swiss small and medium-sized enterprises (SMEs) by developing a conceptual maturity model of managerial values (MM-MV). The MM-MV articulates the extent to which managerial values are embedded within organizations, allowing the analysis of the interrelationship between the degree of values-embeddedness and financial performance in SMEs. The findings suggested that as managerial values become more embedded, financial performance increases; therefore, SMEs exhibiting highly embedded managerial values such as customer-minded, team spirit, innovation-driven reliability, persistency, competency, and engagement tend to financially outperform SMEs that have not fully embedded managerial values throughout the firm.

Today, businesses, organizations and governments attach great importance to digital transformation to meet the needs of their customers, business partners, and employees to adapt to the developing technology in recent years. Digital transformation, which is a challenging and mandatory process, has been and continues to be passed by institutions today. However, the successful management of this transformation without conflict can be realized by accurately detecting new communication technologies and examining, understanding, and implementing the transformation process in detail. This process will be painful, where radical changes will take place in the structure, processes, functions, and business models of the organization. Different challenges may be encountered in each of the startup, execution, and governance subprocesses examined in the digital transformation process. Many conflicts such as time and budget shortages, inadequate digital skills and lack of vision for digital customer processes, cybersecurity threats, human resource shortages, difficulty in managing technology, failure to achieve cloud structure integration, vision, and culture differences are the reasons why this process cannot be managed fluently and accurately. For businesses that focus on this goal, regardless of scale, digital transformation has become a necessity, not an alternative to choose. In this study, the digital transformation process and maturity model were discussed, and technological and digital conflicts were emphasized. It seeks to shed light on the work they will do by making recommendations for institutions to manage this process in the best way.

This chapter presents a structural model à la Leland (1994) that is, at the same time, novel, simple, and able to explain the quotes of credit default swaps (CDS), equity, and equity options. The model gives a closed-form formula for the term structure of default probabilities and can be calibrated to fit the CDS spreads. It also offers closed-form formulas for equity, equity volatility, and equity options. Differently from other structural models, debt has been modeled as a perpetual fixed-rate bond, instead of a zero-coupon bond with finite maturity. Therefore, default can happen at any time, and not only at the bond's maturity. The model (which belongs to the class of first-passage models) specifies default as the first time the firm's asset value hits a lower barrier. The barrier is endogenously determined as a solution of an optimal stopping problem (stockholders’ equity maximization). Equity is seen as a portfolio that contains a perpetual American option to default and can be valuated by using the results of Rubinstein-Reiner (1991) for barrier options. Equity options are valued by a closed-form formula that requires only an extra parameter (leverage) with respect to the standard input list of Black–Scholes–Merton equation. The formula is consistent with the volatility skew that is generally observed in the equity options markets and can be used to estimate the firms’ implied leverage, as it is perceived by traders. The chapter concludes with an application of the model to the case of Goldman Sachs.

The opinion that the spiritual controls the physical gave rise to this chapter. The spiritual in this chapter was regarded as the philosophical and organisational theories controlling the practical aspect of construction supply chain management (CSCM). It was discovered that there is a significant omission in adopting theories to explain supply chain management's (SCM) adaptation and modelling in the construction industry. Therefore, this chapter reviews theories such as resource-based view theory (RBV), principal agency theory (PAT), resource dependency theory (RDT), transaction cost economics theory (TCE) and game theory. Each of the theories was analysed to uncover how they support the practice and variables for modelling the construction supply chain (CSC). The existing models of the CSC were also examined in this chapter. It was found that most models were developed drawing on the frameworks of the global supply chain forum (GSCF) and supply chain operations reference model (SCOR). Owing to the shortcoming of GSCF, this book adopted the framework and principles of SCOR for modelling the management of CSC in the era of the fourth industrial revolution (4IR). Also, most of the existing CSC models, such as the seamless CSCM model, maturity model and others, were developed using the SCOR framework.

This chapter presents a new conceptual framework of institutional research (IR). The framework refines previously studied dimensions of IR and integrates them into the higher order concept of knowledge management. Previously studied dimensions of IR include the institution’s organizational sectors (e.g., academic, human resources), the functions for which information is used (e.g., operations, strategic management), and the resources supporting IR (e.g., technology, funding). The framework innovates by specifying what competencies are required to carry out IR activities and how to assign a level of development to each competency. This operationalization permits the creation of an assessment tool enabling us to move from general and intuitive statements about development to specific and behavioral levels which are actionable. The framework formulation was validated with a group of IR experts in Chile. The framework can be used to assess one institution, to compare an institution to a peer group, or to compare groups of institutions at the regional, national, or international levels.
