Consider the demand for a good whose consumption be chosen prior to the resolution of uncertainty regarding income. How do changes in the distribution of income affect the demand for this good? In this paper we show that ...

We propose a model of delegated portfolio management specialized in alternative investments, i.e., those with a high-return and high-risk profile. It is shown that in this context, as a reward for risk-taking scheme is ...

A well-known prescription in corporate governance is that high-powered incentive contracts such as performance bonuses are an optimal mechanism for aligning managers with shareholders on an efficient investment policy. ...

Maintenance-related decisions are often based on the expected number of interventions during a specified period of time. The proper estimation of this quantity relies on the choice of the probabilistic model that best fits ...

Survival models for situations where some individuals are long-term survivors, immune or non-susceptible to the event of interest are extensively studied in biomedical research. Fitting a regression can be problematic in ...

The q-Weibull model is based on the Tsallis non-extensive entropy [22] and is able to model various behaviors of the hazard rate function, including bathtub curves, by using a single set of parameters. Despite its flexibility, ...

A four-parameter extension of the generalized gamma distribution capable of modelling a bathtub-shaped hazard rate function is defined and studied. The beauty and importance of this distribution lies in its ability to model ...

We define a new two-parameter lifetime model called the zero-truncated Poisson exponentiated gamma distribution. The hazard function of the new distribution has monotonic and non-monotonic shapes, which allows to fit more ...

A five-parameter distribution so-called the beta modified Weibull distribution is defined and studied. The new distribution contains, as special submodels, several important distributions discussed in the literature, such ...
