A MODEL OF MACROEVOLUTION AS A BRANCHING PROCESS BASED ON INNOVATIONS

KELLER-SCHMIDT, STEPHANIE; KLEMM, KONSTANTIN - In: Advances in Complex Systems (ACS) 15 (2012) 07, pp. 1250043-1

with other available traits. Under the assumption that innovations are rare, we obtain a bursty branching process of … speciations. Analysis of the trees representing the branching history reveals structures qualitatively different from those of … as (log n)2 to be compared to log n for random branching. The mean values and standard deviations for the tree shape …

Global alignment of molecular sequences via ancestral state reconstruction

Andoni, Alexandr; Daskalakis, Constantinos; Hassidim, … - In: Stochastic Processes and their Applications 122 (2012) 12, pp. 3852-3874

We consider the trace reconstruction problem on a tree (TRPT): a binary sequence is broadcast through a tree channel where we allow substitutions, deletions, and insertions; we seek to reconstruct the original sequence from the sequences received at the leaves. The TRPT is motivated by the...

Vertical integration to avoid contracting with potential competitors: Evidence from bankers' banks

Brickley, James A.; Linck, James S.; Smith, Clifford W. - In: Journal of Financial Economics 105 (2012) 1, pp. 113-130

We examine a vertical integration decision within the commercial banking industry. During the last quarter of the 20th century, some community banks reduced their traditional reliance on correspondent banks for upstream products and services by joining bankers' banks, a form of business...

A multiperiod model of competition in retail banking

Chizzolini, Barbara - In: Rivista Bancaria - Minerva Bancaria (2011) 3

This paper presents a two-period model of branching behaviour and competition in retail banking. It extends a static … model, from which it borrows most of its theoretical underpinnings, by adding information on banks branching strategies … under the (realistic) assumption that it takes time and strategic adjustments for a bank to reach its optimal branching …

A note on fractional linear pure birth and pure death processes in epidemic models

Garra, Roberto; Polito, Federico - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 21, pp. 3704-3709

In this note we highlight the role of fractional linear birth and linear death processes, recently studied in Orsingher et al. (2010) [5] and Orsingher and Polito (2010) [6], in relation to epidemic models with empirical power law distribution of the events. Taking inspiration from a formal...
