As companies are utilizing technology to manage their business processes, such a marketplace has emerged that is designed to provide third-party availability of business services delivered via Web services technology, particularly in the co...

Competitive information revealed in a marketplace will have significant impact on the learning ability of the participating sellers across market sessions and therefore, on performance of the marketplace. The marketplace that we study in this paper has the following characteristics: a) Products transacted are custom-built – created specifically for a consumer and cannot be resold to other consu...

This paper estimates reduced-form Phillips curves for Brazil with a framework of time series with unobserved components, in the spirit of Harvey (2011). However, we allow for expectations to play a key role using data from the Central Bank of Brazil’s Focus survey. Besides GDP, we also use industrial capacity utilization rate and IBC-Br index, as measures of economic activity. Our findings supp...

To improve accuracy and reliability, Boolean combination (BC) can efficiently integrate the responses of multiple biometric systems in the ROC space. However, BC techniques assume that recognition systems are conditionally-independent and that their ROC curves are convex. These assumptions are rarely valid in practice, where systems face complex environments, and are designed using limited enro...

Data-Driven Inversion-Based Control (D-IBC) is a recently introduced control design method for uncertain nonlinear systems, relying on a two degree-of-freedom architecture, with a nonlinear controller and a linear controller running in parallel. In this paper, extending to the MIMO case a previous result holding for the SISO case, we derive a finite-gain stability sufficient condition for a clo...

This is especially reflected in the development of multi-sided platforms such as Airbnb or Uber that depict the centerpiece of innovative business models as they effectively match demand-side and supply-side participants through advanced technologies. Such marketplace platforms substantially contribute to an emergence of ne...
