Information systems, inter-functional collaboration and innovation in Taiwanese high-tech manufacturing firms

This article investigates whether (1) cross-functional integration within a firm and the use of information systems (IS) that support information sharing with external parties can enhance integration across the supply chain and wider networks and (2) whether collaboration with customers, suppliers and other external parties leads to increased supply chain performance in terms of new product development and introduction of new processes. Data from a high-quality survey carried out in Taiwan in 2009 were used, and appropriate econometric models were applied. Results show that the adoption of IS that enhance information sharing is vital not only for the effective communication with suppliers and with wider network members, but their adoption also has a direct effect across a firm's innovative effort. Cross-functional integration appears to matter only for the introduction of an innovative process. Collaboration with customers and suppliers affected a product's design and its overall features and functionality, respectively. © 2013 Copyright Taylor and Francis Group, LLC.

E-procurement in the aviation industry:value creation potential of B2B e-marketplaces

In academic literature, only limited research has been undertaken in exploring the value creation of B2B (Business-to-Business) e-Marketplace models in the aviation industry. The aim of this publication is a theoretical analysis to explore whether or not B2B e-Marketplaces can make a contribution to the achievement of competitive advantage in procurement in the aviation industry. The research focuses on the potential of B2B e-Marketplaces in terms of improving an airline’s competitiveness in its procurement value chain and discusses empirical results from a survey among international e-Marketplace / portal operators

Operational issues in access networks:past, present, and future

Who you are and what you do:the role of entrepreneurial human capital in the demand and supply of external finance of high-tech start-ups

The existence of adequate financial capital at start-up as well as during the lifetime of a firm is considered to be vital not only for its survival but also for its effective trading and growth, as it can act as a buffer against unforeseen difficulties (Cooper, Gimeno-Gascon, & Woo, 1994; Chandler & Hanks, 1998; Venkataraman & Van de Ven, 1998; Cassar, 2004). Inadequate or inappropriate capital structure is often the most common reason for a large proportion of small business failures (Chaganti, DeCarolis, & Deeds, 1995).

Financial Failure In the Hospitality Industry

The hospitality industry (especially the restaurant segment) has a historically high rate of financial failures. Yet, financial failure in the industry has not received the attention it deserves. In this article, the authors identify basic reasons underlying failed ideas while presenting a study of several hospitality chains that have experienced varying degrees of financial failure. The characteristics and pitfalls of these companies provide the necessary groundwork to explore major lessons to be learned which should aid hospitality management to aviod future business failures.

Realized Matrix-Exponential Stochastic Volatility with Asymmetry, Long Memory and Spillovers

The paper develops a novel realized matrix-exponential stochastic volatility model of multivariate returns and realized covariances that incorporates asymmetry and long memory (hereafter the RMESV-ALM model). The matrix exponential transformation guarantees the positivedefiniteness of the dynamic covariance matrix. The contribution of the paper ties in with Robert Basmann’s seminal work in terms of the estimation of highly non-linear model specifications (“Causality tests and observationally equivalent representations of econometric models”, Journal of Econometrics, 1988, 39(1-2), 69–104), especially for developing tests for leverage and spillover effects in the covariance dynamics. Efficient importance sampling is used to maximize the likelihood function of RMESV-ALM, and the finite sample properties of the quasi-maximum likelihood estimator of the parameters are analysed. Using high frequency data for three US financial assets, the new model is estimated and evaluated. The forecasting performance of the new model is compared with a novel dynamic realized matrix-exponential conditional covariance model. The volatility and co-volatility spillovers are examined via the news impact curves and the impulse response functions from returns to volatility and co-volatility.

Analysis of Poverty Dynamics in Canada (Working Paper 9)

While we know much about poverty (or “low income”) in Canada in a static context, our understanding of the underlying dynamics remains very limited. This is particularly problematic from a policy perspective and the country has been increasingly left out on an international level in this regard. The contribution of this paper is to report the results of an empirical analysis of low income (“poverty”) dynamics in Canada using the recently available “LAD” tax-based database. The paper first describes the general nature of individuals’ poverty profiles (how many are short-term versus longterm, etc.)., the breakdown of the poor population in any given year amongst these different types, and the characterisation of poverty profiles by sex and family type. It then reports the estimation of various econometric models, starting with a set which specifies entry into and exit from poverty in any given year as a function of a variety of personal attributes and situational characteristics, including family status and changes therein, province of residence, inter-provincial mobility, language, area size of residence and calendar year (to capture trend effects). A set of proper hazard models then adds duration effects to these specifications to see how exit and re-entry probabilities shift with the amount of time spent in a poverty spell or after having exited a previous spell. A final set of specifications then investigates “occurrence dependence” effects by including past poverty spells first in an entry model and then with respect to the probability of being poor in a given year. Policy implications are discussed.

From Crisis to Opportunity: Turnaround Strategies of Large Irish Construction Contractors During the Period 2007-2015.

The sudden change in environmental munificence level in the construction sector
during the period 2007 – 2015 provides a natural experiment to investigate strategic
and operating actions of firms, particularly during an environmental jolt. Statistics on
business failures corroborate that neither academics nor practitioners have succeeded
in guiding strategic action during periods of environmental jolt. Despite the recent
increase of turnaround research in the general management domain, its use in the
construction management realm remains underexplored. To address this research
gap, five exploratory case studies of an ongoing PhD study were used to examine the
turnaround strategies of construction contractors during a period of economic
contraction and growth. The findings show that, although retrenchment is often
considered to be a short-term strategy, this is clearly not the case; with the majority of
contractors maintaining the strategy for 6-7 years. During the same period,
internationalization became critical, with the turnaround process shifting towards
strategic reorientation that altered the firms' market domain. The case studies further
suggest that strategic and operational actions resonate quite well with contemporary
practice-based approaches to strategy making. The findings provide valuable
assistance for construction contractors in dealing with organisational decline and in
developing a successful turnaround response.

Seriously, less taxes? Tax reform's effects over labor supply

Using a matching and a difference in differences approach we analyzed the impact of a payroll costs reduction implemented through a tax reform in Colombia on worked hours and hourly income -- Existing studies have found mixed results, while increases in wages are commonly found, the results for employment and worked hours effects are a source of debate with no consensus on sight -- However, in line with earlier revisions of literature, we concluded that the effect of payroll costs reductions is positive and significant on both, worked hours and income -- In this paper, using socioeconomic data from Colombia we found that those individuals a effected by a payroll cost reduction between 2012-2014 exhibited significant increases in both hours and income compared to similar individuals una effected by this framework

Pass-through of International food prices to domestic ination during and after the great recession: evidence from a set of Latin American economies

We examined how international food price shocks have impacted local ination processes in Brazil, Chile, Colombia, Mexico, and Peru in the past decade -- Using impulse-response analysis coming from cointegrated VARs, we wind that international food ination shocks take from one to six quarters to pass through to domestic head-line ination, depending on the country -- In addition, by calculating the elasticity of local prices to an international food price shock, we found that this pass-through is not complete -- We also take a closer look at how this type of shock affects local food and core prices separately, and asses the possibility second round effects over core ination stemming from the shock -- We wind that a transmission to headline prices does occur, and that part of the transmission is associated with rising core prices both directly and through possible second round effects, which implies a role for monetary policy when such a shock takes place -- This is especially relevant given that international food prices have recently been on an upward trend after falling considerably during the Great Recession

O perfil do idoso no mercado de trabalho brasileiro: análise das pnads 2002 e 2012

O presente trabalho tem como finalidade traçar um perfil do idoso inserido no mercado de trabalho Brasileiro. Para a realização deste objetivo, de acordo com a literatura sobre mercado de trabalho e estudos realizados sobre o assunto, utilizaram-se modelos econométricos de resposta qualitativa, o logit e o probit, para a obtenção da probabilidade dos idosos brasileiros estarem inseridos no mercado de trabalho, a partir de variáveis independentes selecionadas. A mostra foi construída a partir de dados fornecidos pela Pesquisa Nacional de Amostra por Domicílios, a PNAD, para os anos de 2002 e 2012. Os resultados dos modelos apresentaram um perfil de idoso inserido no mercado de trabalho brasileiro como sendo residente de áreas rurais, branco, não aposentado e moradores principalmente dos estados do Sul e do Nordeste do país.

Journals and repositories: an evolving relationship?

It is now widely accepted that there are two routes to open access (OA): OA repositories and OA journals. It is often assumed these are distinct alternative parallel tracks. However, it has recently become clear that there is potential for repositories and journals to interact with each other on an ongoing basis and between them to form a coherent OA scholarly communication system. This paper puts forward three possible models of interaction between repositories and journals; services such as arXiv and PubMed Central, and the work carried out by the RIOJA project, are working exemplars and pilot implementations of these models. The key issues associated with the widespread adoption of these models include repository infrastructure development; changing ideas of the ‘journal’, ‘article’, and ‘publication’; version management; quality assurance; business and funding models; developing value-added features; content preservation; policy frameworks; and changing roles and cultures within the research community.

Exchange rate dynamics, structural breaks, and central bank interventions in Colombia

We evaluate the effectiveness of the Colombian Central Bank´s interventions in the foreign exchange market during the period 2000 to 2014 -- We examine the stochastic process that describes the exchange rate, with a focus on the detection of structural breaks or unit roots in the data to determine whether the Central Bank´s interventions were effective -- We find that the exchange rate can be described either by a random walk or by a trend-stationary model with multiple breaks -- In neither cases do we find any evidence that the exchange rate was affected by the Central Bank interventions
