This paper discusses efficiency considerations underlying the widespread exemption of food from sales and value added taxes, in contrast to the distributional considerations usually used to justify them, analyzing the implications for tax policy. Although there are increasing returns in both...

Studying how boards contribute to firm performance and examining implementation costs associated with diversification strategy are domains of growing interest to strategy scholars. We integrate these incipient literatures to examine the role of Peer Independent Executive Directors’ (PIED)...

In this paper, based on the cumulative distribution function (CDF) method (Jradiet al., 2021) for finding the optimal quantile when estimating stochastic frontier models(SFM) with normal-exponential composite error term, we derive an expression to findthe optimal quantile for the SFM with...

This paper investigates the effects of ownership patterns on bank cost and profit efficiencies taking a sample of 607 commercial banks operating in 53 African countries during the period 2005-2015. Using pooled and modified true fixed effects (TFE) stochastic frontier panel approaches, we obtain...

In this paper we consider a novel stochastic frontier model with multi-output multi-input production technology that accommodates non-radial inefficiency in both inputs and outputs. These measures are also observation-specific. To identify them, we use (i) a system model consisting of the...

This paper considers a model that accommodates both output and input-specific inefficiency components (inputslacks). We use a translog function to represent the underlying production technology in which the input slacksare generalized to have both deterministic (functions of exogenous variables)...

We show that under multitasking - where tasks can be substitutes or complements - a specialist worker with an uneven skill distribution can outperform a generalist with higher average skills. We use a principal-agent model to study worker efficiency and welfare. The main result is robust if a...

Purpose: To enable reliable food supply and to remain competitive, grocery retailers need to operate efficient distribution networks. Therefore, the purpose of this paper is to develop and apply a multi-criteria evaluation framework considering the complexity of grocery retail warehouses while...
