Beyond profit maximization: The effect of cooperative governance on insolvency risk in the Brazilian supplementary healthcare industry

open access: yesAnnals of Public and Cooperative Economics, EarlyView.
Abstract Traditional bankruptcy literature has primarily focused on commercial enterprises, often overlooking the unique dynamics of cooperatives and other small organizations. This study addresses this g ap by developing a predictive model for insolvency risk within Brazil's supplementary health sector, encompassing both for‐profit and not‐for‐profit ...

Parallel Vectors Extraction using Bézier Clipping

open access: yesComputer Graphics Forum, EarlyView.
Abstract In this paper, we propose a novel local feature extraction algorithm for the parallel vectors (PV) operator. Our method is based on Bézier clipping, which is a bracketing‐based root finding method that is commonly‐used in computer‐aided geometric design.

PERBANDINGAN KEEFISIENAN METODE NEWTON-RAPHSON, METODE SECANT, DAN METODE BISECTION DALAM MENGESTIMASI IMPLIED VOLATILITIES SAHAM

open access: yesE-Jurnal Matematika, 2016
Black-Scholes model suggests that volatility is constant or fixed during the life time of the option certainly known. However, this does not fit with what happen in the real market. Therefore, the volatility has to be estimated. Implied Volatility is the

Performance comparison between optimization algorithms for asymmetrical cascaded multilevel inverter control

open access: yesAutomatika, 2020
This paper discusses the hardware and control system design of the asymmetric cascade multilevel inverter. The asymmetric cascaded multilevel inverter structure is adopted to minimize bridges, gate drive circuits and DC power source number.

When Density Matters: Hydraulic and Salinity Evolution in Groundwater‐Fed Pit Lakes in Semiarid and Arid Climates

open access: yesGroundwater, EarlyView.
Pit lakes in semiarid and arid regions are often assumed to be terminal sinks for groundwater following mine closure. Using synthetic numerical modeling, we demonstrate that evaporation‐driven density gradients can reverse this behavior, transforming pit lakes into throughflow systems and potentially increasing salinity in adjacent aquifers.

Another Look at the (Ir)Relevance of Long‐Run Risks for Equity Risk Premia

open access: yesJournal of Money, Credit and Banking, EarlyView.
Abstract I investigate the empirical asset pricing implications of a three‐factor macro model that extends the baseline consumption model Consumption Capital Asset Pricing Model (CCAPM) by adding the innovations in expected long‐run consumption growth (consumption growth news) and expected long‐run consumption variance (variance news) as risk factors ...

A Model of Strategic Sustainable Investment

open access: yesMathematical Finance, EarlyView.
ABSTRACT We study a problem of optimal irreversible investment and emission reduction formulated as a nonzero‐sum dynamic game between an investor with environmental preferences and a firm. The game is set in continuous‐time on an infinite‐time horizon.
