Monotonic Knowledge Models,Cycles, Linear Versions and Auctions with Differential,Finite Information

In games of incomplete information where each player's information is represented by a partition of the state space, this paper presents a characterisation of monotonic models in terms of connected partitions and another in terms of versions . A model is monotonic if and only if there is a linear version, and this is true if and only if there is a real‐valued function on the state space such that every partition of the model is connected with respect to this function. These results help us understand the strength of the connectedness assumption on common‐value, second‐price auctions with differential, finite information. We offer a simple sufficient condition for non‐monotonicity to check if models are monotonic.     

The valdez principles: Implications for corporate social responsibility

The Valdez Principles have been formulated to guide and evaluate corporate conduct towards the environment. While at first glance the code appears to impose enormous new responsibilities on firms, a closer analysis indicates that existing regulations and business practices already require businesses to meet many of the environmental goals sought by its proponents. Likely corporate response to the code is examined against this background and with reference to the experience with other voluntary codes of conduct. It would appear that compliance with the code will yield minimal benefits and non-compliance will impose minimum costs for the environmentally-responsible firm.Joao S.

A quality approach to airport management

This paper discusses aspects of airport service quality evaluation using fuzzy multicriteria analysis and the alpha-cut concept. It presents a fuzzy multicriteria methodology for analysing a complex set of quality variables. This methodology develops a step by step set of indicators that allow managers have a holistic view of the quality dimension. It also helps the understanding of cause and effect relation, it helps tracking service quality problems and benchmarking them. From the alpha-cut concept, by defining upper and lower limits, this approach seeks to assist managers in evaluating a complex number of quality criteria and decision-makers’ behaviour. This approach gives managers a broader view of comparative perceptions of quality among the airports in a given sample, by presenting the results of the analysis in fuzzy form and allowing managers to consider different styles of evaluation. The methodology discussed is applied to six Brazilian international airports.     

An Analysis of FEE-HELP in the Vocational Education and Training Sector

The public vocational education and training (VET) system is one of the few areas in Australia's tertiary education system where students are required to pay upfront fees without access to loan assistance. These arrangements may lead to sub‐optimal educational outcomes to the extent that prospective students reject a VET education on the basis of short‐term financial constraints. In this paper we analyse some of the important issues related to the adoption of FEE‐HELP (a 2005 federal government financial instrument based on the Higher Education Contribution Scheme (HECS)). It is argued that income contingent loans of this kind are associated with the advantages of both default‐protection and consumption smoothing. Using data from the first three waves of the Household Income and Labour Dynamics in Australia (HILDA) survey, we examine various empirical issues associated with the adoption of FEE‐HELP in VET, including the extent of private salary returns to VET qualifications. As well, we explore issues related to the public subsidies inherent in the adoption of FEE‐HELP in VET, and illustrate the time periods involved in loan repayments for various assumptions concerning the size of the charge and the future income of VET graduates. Administrative issues are considered, as are the implications for the Commonwealth government with respect to potential subsidies associated with the design parameters. In the 2007–08 Federal Budget, the former government announced a small extension of the FEE‐HELP system into Australian VET, a reform consistent with improved tertiary funding arrangements.     

Technological Centers as a Negotiated Context to Combine Technological Capabilities

Recent perspectives on a capabilities view of the firm often recognize the need for firms to develop an external organization. From a relational view of the industry, the external organization may include economic and non-economic exchange relationships. The decision to combine both types of relationships and its relevance for the firm can be linked to their role for accessing, generating and diffusing knowledge. More often than not, these decisions are however not unilateral. This paper discusses the potential role that Technological Centers (TC’s), created by the collective initiative of some local firms, can play as part of firms’ external organizations and emphasizes TC’s role in connecting economic and non-economic exchange relationships. It is further suggested that the diverse motives and benefits perceived by firms in relating in and across the TC’s and, in general, the relevance of sharing experiences within these contexts, should be seen in the wider context of firms’ specific and idiosyncratic trajectories.     

The London Commercial Property Price Index

Of the top ten global commercial property markets, London’s has had the highest transaction turnover for the past decade according to Real Capital Analytics. Its prime real estate is part of every major European and US institutional investor’s portfolio and London’s market has the most developed commercial property derivatives market outside of the US. Yet, no transaction-based index exists for the London office market. The aim of this study is to fill that gap. Using a comprehensive dataset of transactions from Estates Gazette interactive and Real Capital Analytics, this paper analyzes different repeat-sales estimation strategies and noise filters to produce a quarterly index series from the first quarter of 1997 to the fourth quarter of 2011. In addition, the index series is measured against IPD’s London capital valuation series and the MIT Center for Real Estate New York office market repeat sales index series. Results show that the market turn of the first financial crisis is clearly visible in the transactions-based indices, and that this index leads the capital valuation series by about a year. London’s office market seems to have been affected by the crisis considerably earlier than New York’s market and correlations between the two markets are low.     

Evaluating the employability paradox: When does organizational investment in human capital pay off?

Abstract

The paper explores the notion of the employability paradox which notes that while organizations investing in the career and competency development of their workforce can benefit from higher performance, they also risk losing more employable staff to competitors. Building on contributions from social exchange theory and signalling theory, we develop a model exploring the circumstances under which investment in career development benefits employees and organizations. We test our model in a longitudinal study following graduates entering the labour market. Our results show that when organizations signal that they care about employees by investing in their career development and individuals are receptive to such signals and proactively seek to manage their careers, investment in career development has a positive impact on organizational commitment and intention to stay with one’s employer. Our findings indicate that the idea of the employability paradox is simplistic and lacks theoretical and empirical support.     

Forecasting banking crises with dynamic panel probit models

Banking crises are rare events, but when they occur, their consequences are often dramatic. The aim of this paper is to contribute to the toolkit of early warning models that is available to policy makers by exploring the dynamics and exuberances embedded in a panel dataset that covers 22 European countries over four decades (from 1970Q1 to 2012Q4). The in- and out-of-sample forecast performances of several (dynamic) probit models are evaluated, with the objective of developing common vulnerability indicators with early warning properties. The results obtained show that adding dynamic components and exuberance indicators to the models improves the performances of early warning models significantly.     

Mixed causal–noncausal autoregressions with exogenous regressors

Mixed causal–noncausal autoregressive (MAR) models have been proposed to model time series exhibiting nonlinear dynamics. Possible exogenous regressors are typically substituted into the error term to maintain the MAR structure of the dependent variable. We introduce a representation including these covariates called MARX to study their direct impact. The asymptotic distribution of the MARX parameters is derived for a class of non-Gaussian densities. For a Student likelihood, closed-form standard errors are provided. By simulations, we evaluate the MARX model selection procedure using information criteria. We examine the influence of the exchange rate and industrial production index on commodity prices.
