Comparing Genetic Algorithm Crossover and Mutation Operators for the Indexing Problem

Diptesh Ghosh

The tool indexing problem is one of allocating tools to slots in a tool magazine so as to
minimize the tool change time in automated machining. Genetic algorithms have been suggested
in the literature to solve this problem, but the reasons behind the choice of operators for those
algorithms are unclear. In this paper we compare the performances of four common crossover
operators and four common mutation operators to find the one most suited for the problem.
Our experiments show that the choice of operators for the genetic algorithms presented in the
literature is suboptimal.

Cash Flow Manipulation in State-owned Enterprises

Neerav Nagar and Jaskiran Arora

Manuscript Type: Empirical
Research Question/Issue: We examine whether the state-owned enterprises (SOEs) are more likely to manipulate operating cash flows than private-owned enterprises (POEs). We also test whether the financially distressed SOEs are more likely to exhibit such manipulation.
Research Findings/Insights: Consistent with the arguments about SOEs being inefficient, we find that these are more likely to manipulate operating cash flows than POEs. Our results suggest that SOEs are likely to upward manage reported cash flows by about 6-8% more as compared to POEs. This manipulation in SOEs increases with profitability on one hand and with financial distress on the other i.e. SOEs with higher profitability and higher financial distress demonstrate higher cash manipulations.
Theoretical/Academic Implications: There is dearth of literature on cash flow manipulation and none that presents the evidence on such manipulation by SOEs. The literature shows that firms manipulate cash flows from operations (Lee, 2012; Hollie et al., 2011), and SOEs are more likely to manage earnings (Ding et al. 2007; Wang & Yung, 2011; Liu et al., 2014). We link both sets of literature and present first evidence that SOEs are more likely to upward manage cash flows from operations as compared to POEs.
Practitioner/Policy Implications: Our findings should be of interest to policy makers and accounting standards-setting bodies in emerging markets, suggesting that there is a need to pay closer attention to cash flow reporting practices of SOEs. This might also help the State
to develop a redressal mechanism by bringing about changes in the practices and policies governing SOEs.

Earnings Management in the Construction Industry

Neerav Nagar and Venu Madhav Tatiparti

We find that the existing accounting standards, which mandate the firms in the Construction Industry to follow the Percentage of Completion Method in order to recognize revenue, aid the management in managing earnings. We test for earnings management using the "Unbilled Revenue" accrual and find evidence of earnings management when tested against two incentives/pressures, namely meeting/beating zero earnings benchmark and avoiding violation of debt covenant pressures. The results of this paper hold implications for the standard setters in improving the accounting process with a view to control the managerial discretion that is allowed in the process.

Does good corporate governance constrain cash flow manipulation? Evidence from India

Neerav Nagar and Mehul Raithatha

Accounting frauds like Enron in the United States and Satyam in India are likely to have occurred due to the failure of firm-level corporate governance mechanisms in constraining unethical financial reporting practices. In this paper, we examine whether such corporate governance measures and regulatory reforms constrain the manipulation of operating cash flows, an important firm performance indicator. We focus on an emerging market, India where corporate governance and regulations are weak, and business groups and founding owners dominate the corporate landscape. We find that cash flow manipulation is likely to increase with an increase in the promoters' shareholding. Further, board diligence and better audit fail to curb such manipulation. Our findings suggest that managers seem to move from earnings management towards cash flow manipulation. However, we do find that such manipulation has gone down in the recent years, and diligent boards constrain it, possibly due to the recent steps taken by the Indian Government for improving the corporate governance environment in India.

A new genetic algorithm for the tool indexing problem

Diptesh Ghosh

The tool indexing problem is one of allocating tools to slots in a tool magazine so as to minimize the tool change time in automated machining. This problem has been widely studied in the literature. A genetic algorithm has been suggested in the literature to solve this problem, but its implementation is non-standard. In this paper we describe a permutation based genetic algorithm for the tool indexing problem and compare its performance with an existing genetic algorithm.

Why should I care - its Others Money

Sanjeev Tripathi

We examine the behavior of players when they play with their own vs. other people's money; we investigate this for both dictator and ultimatum games. The results suggest that the behavior of the players differs when they play with their own money as compared to other people's money. In a dictator game, the offer sizes are larger when playing for others, as people seem to offer more when they do not bear the cost. However, in ultimatum games, proposers tend to be more strategic, less risk averse and make lower offers, when they play with other people's money than with their own money.

Does odd or even make a difference

Sanjeev Tripathi

The evidence from literature on ultimatum games suggests that proposers often split the stake equally when they make an offer. In this study we investigate the effect of odd size stakes (OSS) in ultimatum games. OSS prevents the proposer from splitting the stake in two equal parts. The results suggest that when stakes are odd, proposers do not stay in the neighborhood of an equal split, rather they are tempted to move away and make lower offers.

Intention to Participate in Cause Related Marketing:
Influence of Cause

Sonal Kureshi and Sujo Thomas

The most widely accepted definition for CRM is provided by Varadarajan and Menon (1988) and it defines CRM as "a process of formulating and implementing marketing activities that are characterized by an offer from the firm to contribute a specified amount to a designated cause when customers engage in revenue-providing exchanges that satisfy organizational and individual objectives". Several organizations in India like Dabur, Marico, P&G and ITC have implemented this form of social marketing practice.
In the view of the growing significance of CRM in countries like India which have been facing numerous social challenges, it becomes crucial to understand what factors lead to effective implementation of CRM. This study will provide insights into both type and scope of cause and their bearing upon consumer CRM participation intention.
Consumer data was collected using a structured questionnaire from the western region of India. Reponses pertaining to two aspects about the cause of the initiative, 'type of cause' and 'scope of cause' were collected. Results showed that consumer's interest in participation were found to differ significantly across both type of cause and scope of cause.

Intuitionistic Fuzzy Model of Discrete Choice

Manish Aggarwal

The discrete choice models yield a decision-maker (DM)'s choices on the basis of the criteria values. In practice, however, the choices depend on the degree of enjoyment that an evaluating agent derives from a criterion, and which varies from individual to individual. To this end, we introduce an intuitionistic fuzzy variant of multinomial logit model of discrete choice that is able to explicitly consider the imprecision in the utility value, a DM associates with a criterion.
