This study considers the availability of room opportunities collected from a Japanese hotel booking site. We empirically analyze the daily number of room opportunities for four areas. To determine the migration trends of travelers, we discuss a finite mixture of Poisson distributions and the...

This research is focused on the topic of Sharia Governance (SG) in Indonesia. Among the main issues surround corporate governance in Islamic banking is the role of the Sharia Supervisory Board (SSB). The main role of this body is to ensure the compliance of Sharia law along the entire business...

The well-known approximation of the difference between the arithmetic average and geometric average returns as one-half of the variance of the underlying returns is reexamined using Jensen's Inequality. The "defect" in Jensen's Inequality, is given an exlicit formula in terms of the variance...

In this article we use data from the 1998 birth-cohort from the City of São Paulo for live births and data on deaths from the same birth cohort that took place before the first year of life. Information on live birth came from the Information System of Live Births (SINASC) and on deaths came...

This paper develops methods for assessing the sensitivity of empirical conclusions regarding conditional distributions to departures from the missing at random (MAR) assumption. We index the degree of nonignorable selection governing the missing data process by the maximal Kolmogorov–Smirnov...

Assessing the Estimation Uncertainty of Default Probabilities The probability of default (PD) is one of the key variables in credit risk management. By using PD estimates as input to pricing and capital requirement calculations, one should be concerned of how good these estimates are. Confidence...

One learns two main lessons from studying the great quantity of banking efficiency literature. These lessons regard the heterogeneity in results and the absence of a comprehensive review aimed at understanding the reasons for this variability. Surprisingly, although this issue is well-known, it...

This study reviews the empirical literature on banking efficiency by conducting a meta-regression analysis. The metadata-set consists of 1,661 observations retrieved from 120 papers published over the period 2000-2014. While the role of study-design and method-specific characteristics of...
