The antecedents of digital collaboration through an enhanced digital platform for destination management: A micro-DMO perspective

While the tourism sector shifts towards digital transformation, Destination Management Organisations (DMOs) often struggle to adapt to their changing technological environment. This study explores the antecedents of digital collaboration and develops a framework for micro-DMOs to enhance effective destination management through digital technologies. An integrated sequential qualitative approach was adopted by conducting multi-phase interviews, in addition to designing and trialling a real-world trial digital platform. The research provides empirical evidence that digital collaboration is essential for micro-DMOs, necessitating them to transform their current “websites” into digital platforms which act as a hub for business stakeholders to actively be involved in. Antecedents of successful digital collaboration include mutuality, trust, control, and leadership which may be manifested differently from non-digital collaboration. Additionally, the study identifies three aspects for digital collaboration; marketing, networking and knowledge sharing that demands specific attention. Our results have theoretical, methodological, and practical implications for academia, industry and policymakers.     

Relationship regarding the demand for labor between domestic temporary and foreign workers: Korean case

With the progress of globalization, South Korea, one of the emerging industrial countries, has recently witnessed a sharp increase in the number of enterprises that employ foreigners. However, there are only a limited number of studies on the influence that such an increase has had on the labor market in the Republic of Korea. Thus, using ‘Workplace Panel Survey’ data surveyed by the Korea Labor Institute (KLI), this paper examines the relationship concerning the labor demand of an establishment between domestic temporary and foreign workers. Analysis using a bivariate Tobit model shows that a typical Korean firm attempts to employ domestic temporary and foreign workers simultaneously. Further, the empirical analysis found that any establishment that is relatively newly established and has difficulty in recruiting domestic workers hires foreign workers, but there is no evidence that establishments hire foreign workers rather than domestic temporary workers to save on the production cost.     

State wage-payment laws, the Pension Protection Act of 2006, and 401(k) saving behavior

I show empirically that state wage-payment laws, which forbid deductions from wages and salaries without the written permission of the employee, constituted a binding constraint on firms’ choices to adopt automatic enrollment in 401(k) plans prior to 2006.     

Research & development and growth: A Bayesian model averaging analysis

We examine the effect of research and development (R&D) on long-term economic growth using the Bayesian model averaging (BMA) to deal rigorously with model uncertainty. Previous empirical studies, which applied BMA, investigated the effect of dozens of regressors on long-term growth, but they did not examine the effect of R&D due to data unavailability. We extend these studies by proposing to capture the investment in R&D by the number of Nobel prizes in science. Using our indicator, the estimates show that R&D exerts a positive effect on long-term growth. This result is robust to many different parameter and model prior structures as well as to alternative definitions of R&D indicator.     

Separating the Hawks from the Doves: Evidence from continuous time laboratory games

Human players in our laboratory experiment received flow payoffs over 120 seconds each period from a standard Hawk–Dove bimatrix game played in continuous time. Play converged closely to the symmetric mixed Nash equilibrium under a one-population matching protocol. When the same players were matched in a two-population protocol with the same bimatrix, they showed clear movement towards an asymmetric (and very inequitable) pure Nash equilibrium of the game. These findings support distinctive predictions of evolutionary game theory.     

Relationship between positive psychological capital and creative performance

Despite considerable attention to the creative process and its relationship with personal characteristics, there is no published study focused directly on the relationship between the recently recognized core construct of psychological capital (PsyCap) and creative performance. Drawing from a large (N = 899) and heterogeneous sample of working adults, this study investigates PsyCap and its components (i.e., efficacy, hope, optimism, and resilience) as predictors of creative performance. Overall PsyCap predicted creative performance over and above each of the four PsyCap components. Theoretical and practical implications of these findings are considered. Copyright © 2010 ASAC.

Auditing Goodwill in the Post‐Amortization Era: Challenges for Auditors

The elimination of goodwill amortization in 2001 brought about significant change in how companies are required to account for goodwill. This change in accounting also brought with it new challenges for auditors, namely evaluating the reasonableness of management's assumptions related to goodwill valuation. In addition to introducing technical challenges, this task is particularly difficult given the misalignment in incentives it creates between managers who likely prefer to avoid recording an impairment and auditors who seek to minimize the bias in management's impairment testing. This study focuses on the consequences of the misaligned incentives that auditors face under the current goodwill assessment process. We find that the decision to record a goodwill impairment is associated with an increase in the probability of auditor dismissal. Consistent with the presence of significant friction with clients, our results also indicate that the likelihood of auditor dismissals is negatively related to the favorability of the impairment decision. Furthermore, we find that companies impairing goodwill prior to dismissing auditors subsequently employ auditors that are, on average, more favorable to clients in their impairment decisions.     

Why do parents make their children work? A test of the poverty hypothesis in rural areas of Burkina Faso

It is often argued that child labour is caused by poverty. However,much child labour takes place in rural areas characterized bysubstantial labour market imperfections. A model of rural householdlabour supply is developed that provides testable implicationsfor two versions of the poverty hypothesis: that child labouris due to a binding subsistence constraint and that child leisureis a luxury good. We find that in rural Burkina Faso childrendo not provide labour to meet households' subsistence needsand that child leisure is a normal good. The evidence suggeststhat labour market imperfections are a main reason for usingchild labour.
