The exact likelihood function for a space time model

Recently the space time autoregressive moving average models have become popular and this paper derives the exact likelihood function for this model.     

When are preferred shares preferred? Theory and empirical evidence

This paper demonstrates that preferred stock may arise as an optimal security in a tax-induced equilibrium. This result is driven by graduated tax schedules and by uncertainty. In a more general sense, our results can be interpreted as a template for including any security with a different tax treatment in a firm's capital structure. The first part of the paper demonstrates that the Miller equilibrium framework can accommodate more than two securities if different investor classes are taxed differently on each security and the tax schedule for each investor group is upward sloping. We then simplify the tax schedule, but introduce uncertainty, which implies the possibility of bankruptcy and the possible loss of tax shelters. The interaction of tax rates and seniority now affects the contribution of each security to after-tax firm value, as in some states the firm may not be able to pay either interest (or dividends) or even principal to its various claimholders. It is shown why and how these features, i.e. the various tax rates and seniority, determine the financing equilibrium, which is obtained by equating the expected marginal tax benefit of all securities. We demonstrate that non-profitable firms will tend to issue preferred shares whereas profitable firms will not find preferred stock advantageous in our framework. Comparative statics with respect to various tax rates are derived as well. These predictions are tested using a large sample of firms for the last 25 years. The empirical testing broadly confirms the theoretical predictions.     

The perceived impacts of casino gambling on a community

Proposals have been made to legalize a single hotel casino in each of the towns of Adams and Hull, Massachusetts. A telephone survey of a systematic sample of 400 respondents in the Adams and Hull area was conducted in order to assess the perceived impacts of a hotel-casino in each of these locations. The findings show little consensus as to the positive impacts, but much greater agreement over the negative impacts that a hotel casino might have in the respondents' towns. The major factor in predicting respondents' attitudes toward legalization was found to be their perception of the impact a hotel-casino would have on the character of their town. Other major factors were the impact of the hotel-casino on crimes involving drugs and prostitution, the effectiveness of the State government at regulating casino gambling, the respondent's age, the impact of the hotel-casino on the overall standard of living, and the impact of the hotel-casino on jobs for local residents.     

Personnel Management in the Slovak Building Industry： Analysis of Small,Medium-Sized,and Big Building Companies

This paper summarizes the results of the authors＇ research conducted in November 2013 with the aim to analyze the organization and standards of the personnel management in the Slovak building industry. The research was based on the presumption that optimal mastering of the personnel management is a precondition of the success of each building company that wishes to be a continuously prosperous, competitive, and respected economic and social entity. Altogether, 76 small （less than 50 employees）, 77 medium-sized （50-249 employees）, and 21 big （250 and more employees） building companies operating in the territory of the Slovak Republic took part in the research. The results of the research showed that the concept of the personnel management in big building companies （in particular in comparison to most small companies but some medium-sized companies） was more strategic and systematic which is natural given the high numbers of employees of various professions who carry out manifold building works in a huge set of working conditions. However, from the point of view of the current economic development, all building companies have to develop their adaptability to the building market and their capability to master various building works. It is just the personnel management that is used to make it all up provided it is implemented efficiently in a purposeful way in order to keep the stable operation of the building company and satisfaction of various needs of stakeholders including but not limited to employees and clients.     

The effect of coffee price shock on school dropout: new evidence from the 2008 global financial crisis

This article examines the effect of coffee price shock on the school dropout status of children in rural Ethiopia. To identify the effect, I exploit the exogenous coffee price shock caused by the 2008 global financial crisis. Using a unique rural data set collected before and shortly after the crisis, I compare the school dropout status of children in coffee-producing and non–coffee-producing villages. The difference-in-difference estimate suggests that the decline in the global price of coffee during the financial crisis increased school dropout rates among children aged 15–18 in coffee-producing villages. The effect is more pronounced among female children in this age group.     

On the role of sunk costs and asset specificity in outsourcing decisions: a research note

The accounting literature has argued that firms overengage in outsourcing because they tend to ignore the transaction costs involved in buying services from external suppliers. A field experiment with managers of health care organizations shows that decision makers are actually quite sensitive to the asset specificity associated with the “buy” option in an outsourcing decision. However, they also appear inappropriately sensitive to the sunk costs inherent in most real-life outsourcing decisions, and may actually underengage in outsourcing. Prior commitment to internal procurement systematically reduced the willingness to outsource, relative to a pure “make or buy” scenario.     

Brand trust and engagement in social commerce

With the surge in social media (SM) users around the world, the scope of social commerce (SC) in brand engagement is a prominent area of discussion. The present study empirically investigates the effect of social commerce construct (SCC), multi-dimensional constructs of social presence theory (SPT) and consumer generated content (CGC) on brand trust and brand engagement in SC platforms. An online survey was conducted among 625 Indian consumers who had made more than one purchase using SC platforms in the previous 6 months. Structural equation modelling technique was employed for testing the hypotheses and conceptual model. The results suggest that each element of SCC, SPT and CGC positively contributes to brand trust and engagement. Further, the study provides insight into brand trust and brand engagement in SM, which prompts brand usage intention of the consumers. The insights can be used by managers to create long-term customer relationship management action plans that emphasize brand trust and engagement.
