Some Evidence on the Uniqueness of Initial Public Debt Offerings

Debt initial public offerings (IPOs) represent a major shift in a firm's financing policy by both extending debt maturity and altering the public-private debt mix. In contrast to findings for seasoned debt offerings, we document a significantly negative stock price response to debt IPO announcements. This result is consistent with debt maturity and debt ownership structure theories. The equity wealth effect is negatively related to the offer's maturity, and positively related to the degree of bank monitoring. We find that firms with less information asymmetry and firms with higher growth opportunities experience a less adverse stock price response.     

Impact of perceived value on the online purchase intention of base of the pyramid consumers

Despite the voluminous purchasing power of the consumers at the base of the pyramid (BOP), substantial research has not been carried out on their online buying behaviour. This study investigates the factors that trigger the online shopping intention of BOP consumers. We conducted semi-structured in-depth interviews with 52 BOP respondents from India. Our thematic analysis indicates four perceived benefits and five sacrifices influencing BOP consumers' perceived value for online purchases, subsequently determining their adoption behaviour. As a novel contribution to the literature, this study unfolds several unknown factors that motivate/demotivate BOP consumers to buy online using the Value-based Adoption Model (VAM). The findings of this study will help e-commerce marketers enhance BOP consumers' usage intention toward online purchases.     

Finding all Nash equilibria of a finite game using polynomial algebra

The set of Nash equilibria of a finite game is the set of nonnegative solutions to a system of polynomial equations. In this survey article, we describe how to construct certain special games and explain how to find all the complex roots of the corresponding polynomial systems, including all the Nash equilibria. We then explain how to find all the complex roots of the polynomial systems for arbitrary generic games, by polyhedral homotopy continuation starting from the solutions to the specially constructed games. We describe the use of Gröbner bases to solve these polynomial systems and to learn geometric information about how the solution set varies with the payoff functions. Finally, we review the use of the Gambit software package to find all Nash equilibria of a finite game.     

Horseshoe Regularisation for Machine Learning in Complex and Deep Models1

Since the advent of the horseshoe priors for regularisation, global–local shrinkage methods have proved to be a fertile ground for the development of Bayesian methodology in machine learning, specifically for high-dimensional regression and classification problems. They have achieved remarkable success in computation and enjoy strong theoretical support. Most of the existing literature has focused on the linear Gaussian case; for which systematic surveys are available. The purpose of the current article is to demonstrate that the horseshoe regularisation is useful far more broadly, by reviewing both methodological and computational developments in complex models that are more relevant to machine learning applications. Specifically, we focus on methodological challenges in horseshoe regularisation in non-linear and non-Gaussian models, multivariate models and deep neural networks. We also outline the recent computational developments in horseshoe shrinkage for complex models along with a list of available software implementations that allows one to venture out beyond the comfort zone of the canonical linear regression problems.

Non‐parametric regression in clustered multistate current status data with informative cluster size

Datasets examining periodontal disease records current (disease) status information of tooth‐sites, whose stochastic behavior can be attributed to a multistate system with state occupation determined at a single inspection time. In addition, the tooth‐sites remain clustered within a subject, and the number of available tooth‐sites may be representative of the true periodontal disease status of that subject, leading to an ‘informative cluster size’ scenario. To provide insulation against incorrect model assumptions, we propose a non‐parametric regression framework to estimate state occupation probabilities at a given time and state exit/entry distributions, utilizing weighted monotonic regression and smoothing techniques. We demonstrate the superior performance of our proposed weighted estimators over the unweighted counterparts via a simulation study and illustrate the methodology using a dataset on periodontal disease.     

A risk-based decision support framework for selection of appropriate safety measure system for underground coal mines

In the context of underground coal mining industry, the increased economic issues regarding implementation of additional safety measure systems, along with growing public awareness to ensure high level of workers safety, have put great pressure on the managers towards finding the best solution to ensure safe as well as economically viable alternative selection. Risk-based decision support system plays an important role in finding such solutions amongst candidate alternatives with respect to multiple decision criteria. Therefore, in this paper, a unified risk-based decision-making methodology has been proposed for selecting an appropriate safety measure system in relation to an underground coal mining industry with respect to multiple risk criteria such as financial risk, operating risk, and maintenance risk. The proposed methodology uses interval-valued fuzzy set theory for modelling vagueness and subjectivity in the estimates of fuzzy risk ratings for making appropriate decision. The methodology is based on the aggregative fuzzy risk analysis and multi-criteria decision making. The selection decisions are made within the context of understanding the total integrated risk that is likely to incur while adapting the particular safety system alternative. Effectiveness of the proposed methodology has been validated through a real-time case study. The result in the context of final priority ranking is seemed fairly consistent.     

California’s Three Strikes Law Revisited: Assessing the Long-Term Effects of the Law

Previous studies on the three strikes legislation in California draw conclusions based on data immediately following the passage of the law, which cannot account for the full deterrent effect of the law. Moreover, they do not account for the incapacitation effect. Distinguishing between deterrence and incapacitation is important for determining the efficacy of the law. Using data from 1991 to 2009, this paper is the first to examine the long-run effects. Our results show that the law had a significant deterrent effect on all crimes, including non-triggering offenses. Overall, the incapacitation effect is less significant. Further, enhanced penalties cause some felons to substitute between violent crimes and property crimes which carry a lower sentence. However, there is little evidence of substitution within crime categories. Surprisingly however, the added deterrent effect of the third strike is significantly smaller than for the second strike. The small marginal deterrence from the third strike also raises questions about the justification for such extreme severity of punishment.     

Effects of Industry‐ and Region‐Specific Acquisition Experience on Value Creation in Cross‐Border Acquisitions: The Moderating Role of Cultural Similarity

Based on a sample of 222 cross‐border acquisitions by US firms in the service sector, our study examines the effects of acquiring firms' prior cross‐border acquisition experience in the same industry and geographic region as the acquired firm on shareholder value creation. Using the BHAR (buy‐and‐hold abnormal returns) methodology, we find that higher levels of industry‐specific and region‐specific acquisition experience translate into greater shareholder value creation for acquiring firms in subsequent acquisitions. In addition, our results indicate that the effects of industry‐specific acquisition experience on acquisition performance are contingent on the level of cultural similarity between the acquiring and acquired firm countries, with the benefits of prior experience being greater in acquisitions undertaken in culturally similar countries. We also find that the moderating effects of cultural similarity on the relationship between industry‐specific acquisition experience and value creation are contingent on the level of prior region‐specific acquisition experience possessed by the acquiring firm.     

The impact of improved highways on Indian firms

India's Golden Quadrilateral Program, a major highway project, aimed at improving the quality and width of existing highways connecting the four largest cities in India. It affected the quality of highways available to firms in cities that lay along the routes of the four upgraded highways, while leaving the quality of highways available to firms in other cities unaffected. This feature of the project allows for a difference-in-difference estimation strategy, where status on and off the improved highways, and distance from them, are used as treatment variables. This strategy is implemented using data from the 2002 and 2005 rounds of the World Bank Enterprise Surveys for India. Firms in cities affected by the Golden Quadrilateral highway project reduced their average stock of input inventories by between 6 and 12 days’ worth of production. Firms in cities where road quality did not improve showed no significant changes. The reduction in stocks of input inventories also varied inversely with the distance between the city in which a firm was located and the nearest city on an improved highway. Firms on the Golden Quadrilateral were also more likely to have switched the supplier who provided them with their primary input, suggesting that they saw reason to re-optimize their choice of supplier after the arrival of better highways. Consistent with these findings, firms on the improved highways reported decreased transportation obstacles to production, while firms in control cities reported no such change.
