Asymptotics for Autocovariances and Integrated Periodograms for Linear Processes Observed at Lower Frequencies

One of the most frequently used class of processes in time series analysis is the one of linear processes. For many statistical quantities, among them sample autocovariances and sample autocorrelations, central limit theorems are available in the literature. We investigate classical linear processes under a nonstandard observation pattern; namely, we assume that we are only able to observe the linear process at a lower frequency. It is shown that such observation pattern destroys the linear structure of the observations and leads to substantially different asymptotic results for standard statistical quantities. Central limit theorems are given for sample autocovariances and sample autocorrelations as well as more general integrated periodograms and ratio statistics. Moreover, for specific autoregressive processes, the possibilities to estimate the parameters of the underlying autoregression from lower frequency observations are addressed. Finally, we suggest for autoregressions of order 2 a valid bootstrap procedure. A small simulation study demonstrates the performance of the bootstrap proposal for finite sample size.     

ASSESSING THE EFFECT OF PUBLIC SUBSIDIES ON FIRM R&D INVESTMENT: A SURVEY

This survey examines the empirical literature on the relationship between public R&D subsidies and private R&D investment over the past five decades. The survey reveals a considerable heterogeneity of empirical results that cannot be explained fully by methodological issues. We aim to provide further explanations of the possible causes of that heterogeneity. In particular, we emphasise a set of issues that, in our view, are critical to understanding the potential effect of public R&D subsidies on private R&D spending. Special attention is paid to the dynamic aspects and composition of firm R&D, the constraints faced by the firm (such as financial constraints), and the amount and source of public subsidies. None of these issues have been investigated in depth. We formulate a set of research assumptions to guide future empirical research in this field.     

Política de la legislación laboral en el sur de China. Las cámaras de comercio y otros organismos extranjeros ante las leyes sobre negociación colectiva

En 2010, tras la huelga en Honda, hubo protestas laborales en toda China. Los gobiernos de Shenzhen y Guangdong reaccionaron desempolvando los proyectos de Decreto sobre consulta colectiva y de Normativa sobre gestión democrática de las empresas, retirados con anterioridad. Pero tras la oposición frontal de cámaras de comercio y organismos gubernamentales extranjeros, hongkoneses y taiwaneses, volvieron a retirarse. Mediante entrevistas, los autores revelan los medios de influencia en la legislación laboral china de estos actores, cuyas actitudes dependen de la posición de las empresas representadas en las cadenas mundiales de producción y del modelo de relaciones laborales de su país o territorio de origen.     

CONVERTIBLE BOND PRICING MODELS

Convertible bonds are an important segment of the corporate bond market, with worldwide outstandings approaching US$235 billion. Simple pricing models value a convertible bond as being equivalent to a straight bond with an embedded option that enables the bond holder to convert to a specific amount of common stock. The straight bond is subject to both interest rate and credit risk, whereas the option to convert is dependent on the underlying stock price, which exposes the convertible bond holder to equity risk. The complexity of these features means that convertible bonds tend to be treated casually in major derivatives and corporate finance textbooks. This paper presents a survey of the theoretical and empirical aspects of convertible bond pricing. The limitations of these studies are highlighted to identify those areas of research that may improve the valuation process and facilitate the application of these securities for corporate financing.     

THE IMPACT OF LABOR MARKET REGULATION ON EMPLOYMENT IN LOW‐INCOME COUNTRIES: A META‐ANALYSIS

Controversy over labor market policy often centers on achieving a balance between preventing worker exploitation, and avoiding loss of productivity or employment through excessive regulation. Although the literature documenting the impact of labor market regulation on employment is extensive, there is a dearth of evidence on the impact of such policies in low‐income countries (LICs). Since it is easier for workers, especially women, to slip into the informal sector in LICs, regulations are likely to have stronger impacts on formal employment in these countries (but lower impacts on unemployment). We systematically reviewed available research from countries that are, or were until recently, LICs. Most studies document that more stringent labor regulations are associated with lower formal sector employment and higher informal sector employment. We also conducted a metaregression analysis of the impact of minimum wages on formal and informal employment. After controlling for publication bias, higher minimum wages are associated with lower formal employment and a higher share of informal workers.     

Stakeholder Engagement: Defining Strategic Advantage for Sustainable Construction

Although sustainable development is increasingly becoming a part of business plans, it is unclear what makes the economic, social and environmental dynamics strategically compatible. This research examines which of the following in sustainable development – government policy, managerial attitude and stakeholder engagement – is the most influential on the profitability of companies in the UK construction sector. Quantitative and qualitative analyses were rendered through a survey and semi‐structured interviews. Patterns of ambiguity in legislation were discovered as an obstacle for changing the sector's mind‐set. Stakeholder engagement was identified as the defining factor increasing managers' awareness, helping legislation to be effectively implemented and making sustainability highly appealing to clients. These findings indicate that to gain competitive advantage, companies should embark on long‐term strategic alliances which adopt the proposals of environmental non‐governmental organisations and closely follow public opinion. This, strengthens brand equity, allows for premium pricing, increases market share and maximizes profit. Copyright © 2011 John Wiley & Sons, Ltd and ERP Environment.     

Fertility and female employment dynamics in Europe: the effect of using alternative econometric modeling assumptions

We investigate the direct and long‐run effects of fertility on employment in Europe, estimating dynamic models of labor supply under different assumptions regarding the exogeneity of fertility and modeling assumptions related to initial conditions, unobserved heterogeneity and serial correlation in the error terms. We find overall large direct and long‐run effects of giving birth on employment probabilities, and these effects differ considerably across countries. We find that within countries the results are sensitive to the statistical assumption made on initial conditions, the inclusion of serial correlation and the assumption of strict exogeneity of children. However, the pattern across countries is robust to these assumptions. We show that such patterns are largely consistent with prevailing institutional differences related to the flexibility of the labor markets and family policies.

Does Managerial Behavior Determine Farm Technical Efficiency? A Case of Grape Production in an Economy in Transition

This study explores how farmers' managerial behavior in their production planning processes influences the economic performance of their farms, measured through input‐oriented and output‐oriented technical efficiency. A conceptual framework in which differences in managerial behavior were assumed to be due to bounded rationality was developed. The 3‐year means (2006–2008) from a panel data set on grape‐producing family farms in FYR Macedonia were analyzed. Technical efficiency was estimated with the nonparametric data envelopment analysis approach. The impact of farmers' managerial behavior was assessed in a second‐stage regression. The results suggest that bounded rationality in farmers' production planning decisions causes inefficiency. Copyright © 2011 John Wiley & Sons, Ltd.     

Business is Show Business: Management Presentations as Performance

While there is continual scholarly interest in the ‘organization as theatre’ metaphor, extant dramaturgical perspectives limit the ability to account for aesthetic experiences in theatrical situations. This study provides a different methodological lens for looking at ‘theatre’ in organizations and illustrates that an inclusion of performance theory can be particularly valuable for understanding aesthetic techniques which are increasingly employed in organizations. Responding to calls for aesthetic studies, this article analyses large‐scale management presentations such as annual general meetings, press conferences, and analyst meetings ‘as performance’ instead of re‐labelling them as if they were drama. Drawing on the latest theatre theory and introducing a tool for performance analysis, the study accounts for the aesthetic experience and describes the complex interplay of scenography, lighting, clothing, managers' performance style, rhetoric, and audience interaction, showing that these organizational events are co‐created and contested theatrical performances with a potential for resistance and possible change as well as for persuasion.
