The Institutional Determinants of Private Equity Involvement in Business Groups: The Case of Africa
2018
This study examines the governance attributes of post-IPO (initial public offering) retained ownership of private equity in business group constituent firms in contrast to their unaffiliated counterparts, in 202 newly listed firms in 22 emerging African economies. We adopt an actor centered institutional-theoretic perspective in rationalizing institutional voids and the advantages of maintained governance by both business angels (BA) and venture capital (VC) private equity. Our findings reveal private equity retain higher post-IPO ownership in business group constituents compared to unaffiliated firms and that this is inversely moderated in the context of improving institutional quality – w…
¿Quién paga, quién gana? El caso de la venta del BdV
2016
ResumenEl proceso de venta del Banco de Valencia gestionado por el FROB duró 10 días. La venta se adjudicó a CaixaBank por un euro después de recibir 5.500 millones de fondos públicos. El informe de Oliver Wyman de 2012 motivó dicha reanudación. En él se estimaban unas necesidades de 1.846 millones en el escenario base, escenario que ha sido peor que el real.Este trabajo analiza el valor del BdV. Los resultados indican que el valor mínimo del BdV para CaixaBank es de más de 4.000 millones de euros. Sin embargo, no se ha podido determinar el porqué de esta diferencia. Diferencia reconocida en las cuentas de CaixaBank. Sin embargo, el precio pagado, un euro, después de un sacrificio muy impor…

Milnor-Witt Motives
2020
We develop the theory of Milnor-Witt motives and motivic cohomology. Compared to Voevodsky's theory of motives and his motivic cohomology, the first difference appears in our definition of Milnor-Witt finite correspondences, where our cycles come equipped with quadratic forms. This yields a weaker notion of transfers and a derived category of motives that is closer to the stable homotopy theory of schemes. We prove a cancellation theorem when tensoring with the Tate object, we compare the diagonal part of our Milnor-Witt motivic cohomology to Minor-Witt K-theory and we provide spectra representing various versions of motivic cohomology in the $\mathbb{A}^1$-derived category or the stable ho…
Semiclassical Gevrey operators and magnetic translations
2020
We study semiclassical Gevrey pseudodifferential operators acting on the Bargmann space of entire functions with quadratic exponential weights. Using some ideas of the time frequency analysis, we show that such operators are uniformly bounded on a natural scale of exponentially weighted spaces of holomorphic functions, provided that the Gevrey index is $\geq 2$.
Les déterminants de la qualité des conseils d'administration français
2005
International audience; Dans cet article, nous vérifions si la "qualité" des conseils d'administration dépend de la structure de propriété et de la politique financière des grandes sociétés cotées en bourse, caractérisées par une séparation de la décision (control) et du contrôle (ownership). En nous basant sur la théorie de l'agence, nous considérons que les conseils sont de meilleure qualité lorsqu'ils comprennent une fraction élevée d'administrateurs indépendants et/ou lorsque les fonctions de direction générale et de présidence du conseil sont dissociées. Pour les 85 sociétés cotées en bourse de notre échantillon, nous confirmons notamment que la qualité des conseils croît avec la fract…
El componente de selección adversa de la horquilla de precios cotizada: una revisión de los modelos de estimación
2005
-Jose.E.Farinos@uv.es -Ana.M.Ibanez@uv.es Una de las principales preocupaciones en el área de la microestructura del mercado ha sido la estimación de los componentes no observables de la horquilla de precios a partir de las series de datos que proporcionan los mercados financieros, despertando quizá un mayor interés el de selección adversa por la implicaciones que supone la existencia del mismo. Esto ha provocado el desarrollo de numerosos modelos empíricos que, basándose en las propiedades estadísticas de las series de precios, proporcionan dichas estimaciones. La mayor disponibilidad de datos existentes en los mercados ha permitido el desarrollo en los últimos años de modelos basados en t…
Compactness of Fourier integral operators on weighted modulation spaces
2019
Using the matrix representation of Fourier integral operators with respect to a Gabor frame, we study their compactness on weighted modulation spaces. As a consequence, we recover and improve some compactness results for pseudodifferential operators.
What Can International Finance Add to International Strategy?
2011
This chapter focuses on the role of corporate financial strategies to improve firms’ market valuations, and thus lower their cost of capital. The identification of successful strategies is accomplished within an overall strategic framework and related to how the firm perceives the degree of international financial integration. Five strategies for how to break out of a segmented, thin domestic capital market are highlighted together with historical success cases. The chapter illustrates the linkages between business strategy, firm motivation, and various financial strategies. JEL: F21, F23, F36, G32, G34.
Multiplicity and history have a detrimental effect on survival in patients with T1G3 bladder tumors selected for conservative treatment.
2008
Purpose: In the absence of Tis tumor we assessed whether history and multiplicity have a detrimental effect on conservative treatment in carefully selected patients with T1G3 bladder carcinoma. Materials and Methods: Between January 1976 and December 1999, 165 select patients with T1G3 bladder tumors were conservatively treated with transurethral resection plus adjuvant intravesical therapy. Patients with concomitant or previous Tis, previous T1G3, tumor size greater than 3 cm and more than 3 lesions were excluded from analysis. Repeat transurethral resection was not routinely performed. However, cytology had to be negative for atypia before the start of adjuvant intravesical therapy. Resul…
