We develop a new Data Envelopment Analysis (DEA)-based methodology for measuring the efficiency of Decision Making Units (DMUs) characterized by multiple inputs and multiple outputs. The distinguishing feature of our method is that it explicitly includes information about output-specific inputs and joint inputs in the efficiency evaluation. This contributes to opening the " black box " of effic...

This paper measures the technical efficiency, super-efficiency, slacks, and input/output targets for large Indian pharmaceutical firms according to ownership by applying Data Envelopment Analysis (DEA) approach. The paper uses raw material, salaries & wages, advertisement & marketing and capital usage cost as input variables and net sales revenue as output variable. The super-efficiency model i...

Unlike conventional wisdom, I find more constrained firms have significantly higher innovative efficiency (IE) measured by patent citations (or counts) per dollar of R&D (research and development). This constraints-IE relation is robust to measures of financial constraints, measures of IE, and different sets of control variables. Furthermore, this effect exists only among firms with strong mana...

One of the most important issues in strategic management is enhancing employees’ motivation to contribute in the implementation of strategies; because they usually do not pay necessary attention to strategies. Accordingly, it is required to consider and calculate their roles in implementing strategies. In terms of employees’ role in the organization, they have managerial (goal setter) and/or no...

The aim of this study is to investigate the relationship between managerial ability and firm performance. First, we introduce a new two-stage DEA model with a fuzzy multi-objective programming approach for evaluating the performance of companies listed on the Tehran Stock Exchange. In this regard, the stable operation of companies, into two sub-process, have divided, which includes the profitab...

In this paper, we show the importance of accounting for heterogeneity among sample firms in stochastic frontier analysis. For a fairly homogenous sample of German savings and cooperative banks, we analyze how alternative theoretical assumptions regarding the nature of heterogeneity can be modeled and the extent to which the respective empirical specifications affect estimated efficiency levels ...

Operational performance evaluation and process improvement in hotels have been the focus of several studies, a number of which have used Data Envelopment Analysis (DEA) to evaluate the operational performance of hotels in different destinations. This study sets out to evaluate the operational efficiency of twenty-three tourist hotels in Taipei over five years (2003 to 2007) using DEA models and...

We present a hospital non-price competition model to investigate two important concerns when a global budgeting system is applied to the expenditure cap policy and the expenditure target policy. Our results indicate that (1) the treadmill effect, (describing a phenomenon whereby health care providers provide more health care services with a lower reimbursed price under the expenditure cap polic...
