Implementing circular economy in the textile and clothing industry

This research reveals the current state of the circular economy (CE), challenges and opportunities of implementing CE and interventions that could facilitate effective implementation of CE in the textile and clothing (TC) industry. The study uses a survey method within 114 TC companies based in Bangladesh, Vietnam and India revealing the correlation of CE fields of action (take, make, distribute, use and recover) with sustainability (economic, environmental and social) performance. The lack of financial, technological and human resources along with management's reluctance and end-user's indifference to sustainability is the biggest challenge for CE implementation. The research further derives that the TC firms are unable to eradicate the challenges to CE implementation without a holistic approach that involves the collective effort from the industry, host government's incentives, their buyers and above all the conscience of the end-users. Finally, the study reveals that the collaborative efforts, knowledge sharing in sustainability management across the value chain and marketisation of the waste recycling, among others, are a few actions the stakeholders of the TC industry must adopt for implementing CE successfully.     

Impact of traffic citations to reduce truck crashes on challenging roadway geometry

Wyoming's Interstate 80 has one of the highest truck crash rates in the United States. This is due to a variety of reasons, including high percentage of truck traffic, adverse weather conditions and mountainous terrain. These factors have caused the Wyoming Highway Patrol (WHP) to spend extensive resources on inspecting commercial vehicles and enforcement of traffic laws in this corridor. This study estimated the correlation between traffic citations and truck crashes. In addition, the paper evaluated the increased risk of truck crashes in adverse weather and road conditions. The explanatory variables included geometric features, weather condition, traffic volume and types of citations. This research concluded that speeding related citations and truck crashes are negatively correlated, and the risk of truck crashes is significantly higher when weather is not clear, and the road is not dry.     

Join hands or walk alone? Evidence on lobbying for trade policy in India

Using primary evidence for 146 Indian manufacturing firms, I examine single and dual lobbying strategies for trade policy influence, and the factors driving firm's choice of these strategies. Firms can adopt a single strategy, by lobbying collectively as a group (Join Hands), or lobbying individually as a firm (Walk Alone). Firms can also adopt a dual strategy, that is, a combination of collective and individual lobbying. The choice of strategy is affected by sector concentration and by tradeoffs between lobbying intensity for sector‐wide and firm‐specific outcomes. The following findings are new for India: First, majority of Indian firms (more than 64% in the sample) use a dual strategy, suggesting the importance to better understand what drives dual strategies. Second, the likelihood of adopting a dual lobbying is higher in sectors that are characterized by low concentration (dispersion is higher), indicating a strong competition effect over free‐riding. Third, relative to the single strategy of collective lobbying, Indian manufacturing firms are likely to join hands while walking alone when targeting firm‐specific outcomes, but prefer to walk alone (single strategy of individual lobbying) when there are tradeoffs between different outcomes, to react quickly. Finally, the availability of resources and firm's perceived effectiveness of its lobbying are significant drivers for the strategy choice.     

Drivers of technical efficiency in Malaysian banking: a new empirical insight

Restructuring and rationalisation of Malaysian banking in 2000 and the subsequent policy of deregulation and liberalisation adopted by Bank Negara Malaysia (BNM) have resulted in a significant transformation of Malaysian banking. Banks are now poised to play a pivotal role in the economic transformation of the economy as envisaged in the Financial Sector Blue Print 2011–20 of BNM. Using the data envelopment analysis technique, the technical efficiency of 19 commercial banks (8 domestic banks and 11 foreign banks) operating in Malaysia during 2005–12 is evaluated. Then, using bootstrap‐corrected efficiency scores, the drivers of bank efficiency were estimated using the Tobit regression approach. Results clearly show that three large domestic banks are not only more efficient than their counterparts, but are also more efficient than the foreign banks. Bank size and return on assets are found to be the significant drivers of technical efficiency of Malaysian banks. Capital adequacy and the advances to deposit ratio also have a role in driving technical efficiency. The results also indicate that banks that are more effective in managing credit risk, as reflected in a lower level of non‐performing assets as a percentage of total assets, and have lower levels of personnel expenses to total assets, are more efficient. The findings have significant implications at the individual bank level and also at the policy level.     

The Value Relevance of Corporate Social Responsibility Expenditure: Evidence from Regulatory Decisions

We examine the value relevance of the corporate social responsibility (CSR) expenditure of Bangladeshi banks from 2007–2014 in response to a regulatory directive on banking firms’ engagement in CSR activities. We find a positive association between CSR expenditure and a firm's market value. Evidence of an inverse U-shaped curvilinear association between CSR expenditure and market value suggests that the impact of CSR expenditure on a firm's market value has a certain limit. We also document that unexpected or abnormal components of CSR expenditure comprise value-relevant information. Our study provides empirical evidence to support the value relevance of CSR expenditure as an explanation for why firms should invest in CSR and why they should inform various stakeholders about their CSR activities.     

Consumer preferences and product and process R&D

Firms often conduct both product and process R&D. Consumer preferences typically play a vital role in determining these R&D choices. The economics literature, however, has mostly ignored the interrelationship between the R&D choices of firms and consumer preferences. Istudy product and process R&D from the perspective of their relationship with consumer preferences. In doing so, I find a novel distinction between the two kinds of R&D. This distinction can explain several empirical observations regarding firms' choices of the two, and can also potentially enable us to better empirically identify the two.     

Estimation from two-stage unequal probability sampling with missing units

A formula is presented for an unbiased estimator for the variance of an unbiased estimator of a survey population total as well as for an unbiased estimator of its variance based on sampling in two-stages following Rao et al. J Roy Stat Soc B 24: 482–491 (1962) scheme in both stages when the originally selected units in both stages cannot be fully covered in the survey but are to be randomly sub-sampled. The development is helpful to tackle non-responses if assumed to have occurred at random in either or both the stages     

Generic Competition in the US Pharmaceutical Industry

We develop a simultaneous equations estimation framework to understand the interactions among generic entry, prices, and market shares. We base our estimates on a panel data sample of 40 brand‐name drugs that first experienced generic competition during the period July 1992–January 1998. We find that generic share and price are simultaneously determined, while the number of generic entrants is a key determinant of generic market share and the generic‐to‐brand price ratio. In addition, we find generic competition to be particularly intense for blockbuster drugs, which experience significantly more generic entrants, price erosion, and generic penetration than other drugs.     

An optional scrambled randomized response technique for practical surveys

Eichhorn and Hayre (J Stat Plan Inference 7:307–316, 1983) introduced the scrambled response technique to gather information on sensitive quantitative variables. Singh and Joarder (Metron 15:151–157, 1997), Gupta et al. (J Stat Plan Inference 100:239–247, 2002) and Bar-Lev et al. (Metrika 60:255–260, 2004) permitted the respondents either to report their true values on the sensitive quantitative variable or the scrambled response and developed the optional randomized response (ORR) technique based on simple random sample with replacement (SRSWR). While developing the ORR procedure, these authors made the assumption that the probability of disclosing the true response or the randomized response (RR) is the same for all the individuals in a population. This is not a very realistic assumption as in practical survey situations the probability of reporting the true value or the RR generally varies from unit to unit. Moreover, if one generalizes the ORR method as developed by these authors relaxing the ‘constant probability’ assumption, the variance of an unbiased estimator for the population total or mean can not be estimated as this involves the unknown parameter, ‘the probability of revealing the true response’. Here we propose a modified ORR procedure for stratified unequal probability sampling after relaxing the assumption of ‘constant probability’ of providing the true response. It is also demonstrated with a numerical exercise that our procedure produces better estimator for a population total than that provided by the method suggested by the earlier authors.     

Entry Threats and Inefficiency in ‘Efficient Bargaining’

We study limit pricing in a model of entry with asymmetric information, where the incumbent firm's wage is endogenously determined through ‘efficient bargaining’ with its union. In the presence of entry threat, the incumbent firm‐union pair may face a conflict between rent sharing and transmitting its cost information. When the wage is not observable to outsiders and employment is the only signalling instrument, over‐employment features in all entry deterring contracts. When the wage is also observable, information transmission becomes easier. Most of the time, then, but not always, the efficient contract deters (induces) entry against the low (high) cost incumbent.
