Fast Kernel Smoothing of Point Patterns on a Large Network using Two‐dimensional Convolution

We propose a computationally efficient and statistically principled method for kernel smoothing of point pattern data on a linear network. The point locations, and the network itself, are convolved with a two‐dimensional kernel and then combined into an intensity function on the network. This can be computed rapidly using the fast Fourier transform, even on large networks and for large bandwidths, and is robust against errors in network geometry. The estimator is consistent, and its statistical efficiency is only slightly suboptimal. We discuss bias, variance, asymptotics, bandwidth selection, variance estimation, relative risk estimation and adaptive smoothing. The methods are used to analyse spatially varying frequency of traffic accidents in Western Australia and the relative risk of different types of traffic accidents in Medellín, Colombia.     

Arbitrage and equilibrium with portfolio constraints

We consider a multiperiod financial exchange economy with nominal assets and restricted participation, where each agent’s portfolio choice is restricted to a closed, convex set containing zero, as in Siconolfi (Non-linear Dynamics in Economics and Social Sciences, 1989). Using an approach that dates back to Cass (CARESS Working Paper, 1984; J Math Econ 42:384–405, 2006) in the unconstrained case, we seek to isolate arbitrage-free asset prices that are also quasi-equilibrium or equilibrium asset prices. In the presence of such portfolio restrictions, we need to confine our attention to aggregate arbitrage-free asset prices, i.e., for which there is no arbitrage in the space of marketed portfolios. Our main result states that such asset prices are quasi-equilibrium prices under standard assumptions and then deduces that they are equilibrium prices under a suitable condition on the accessibility of payoffs by agents, i.e., every payoff that is attainable in the aggregate can be marketed through some agent’s portfolio set. This latter result extends previous work by Martins-da-Rocha and Triki (Working Paper, University of Paris 1, 2005).     

Promoting child health and nutrition in India

This article discusses the reasons for poor child nutrition in India. Inadequate advice to mothers in poor rural communities about breast milk supplements could allow progressive erosion of breast feeding practices in the face of aggressive promotion from baby food manufacturers. Health workers need better information about possible supplements produced from locally available foods if nutrition education programs are to succeed. The author warns of the detrimental effect on nutritonal status of the deemphasis of school health nutrition programs in India, and points to the need for a nutrition component as an integral part of rural employment/development programs.     

Exchange rate policies in Asia in an era of financial globalisation: An empirical assessment

Ebbs and flows of capital have complicated macroeconomic policy management for all emerging market and developing economies (EMDEs) regardless of whether they have adopted flexible or managed exchange rate regimes. In the light of the renewed interest in the trilemma versus dilemma debate, we contribute to the related literature by presenting an empirical analysis of exchange rate flexibility and intervention for selected Asian EMDEs over the time period 2001–2016. In addition to estimating augmented Frankel–Wei regressions, we employ a generalised auto‐regressive conditional heteroscedasticity (GARCH) model to assess the extent of foreign exchange (FX) intervention and whether there exist any asymmetries in the way countries intervene. Our results show that although there is greater flexibility in exchange rates, there is evidence of some countries potentially using FX intervention to manage currency movements. We also find evidence of asymmetry in intervention where exchange rate volatility responds more emphatically to FX sales than purchases.     

Logistic regression and probability of default of developing countries debt

This paper presents a logistic regression model for determining the default probability of developing countries debt. The study incorporates 79 countries over a period of 19 years. The model predicted the default of Mexico, Brazil, and Argentina two years in advance. Results indicate that the model has high predictive power.     

Improving customer experience in tourism: A framework for stakeholder collaboration

Tourism represents a service industry replete with unique complexities since a tourist's overall experience is modulated by multiple stakeholders, e.g., immigration officials at airports, policy makers responsible for investment in transportation infrastructure and managers at various tourist attractions. Effective management of customer satisfaction in this service sector entails cross-functional collaboration and a transparent measurement scheme that clearly delineates the impact of each stakeholder's actions on overall customer experience. In this paper, we propose a simple conceptual framework for stakeholder collaboration in tourism. A four-phase customer experience measurement process is developed to prioritize resource allocation and to increase tourists' advocacy levels for a destination. The proposed measurement framework has wide applicability and can also be exercised in the context of other public sector services, e.g., mass transit systems. We illustrate the process using an empirical case study at Chennai, a tourist destination in India and provide a number of substantive insights that are valid for this destination.     

A comparison of voluntary and mandated climate change-related disclosure

This study draws on legitimacy theory to investigate the relationship between mandatory disclosure of greenhouse gas emissions by companies that are subject to specific environmental legislation (the Australian National Greenhouse Energy Reporting Act 2007) and the level of voluntary environmental disclosures. Using a sample of 535 observations, we find that i) Overall, legislation-affected companies increase their disclosures compared with non-affected companies, ii) As many companies reduce their disclosures as increase them, iii) there is an increase in the level of emissions volume disclosures in legislation-affected companies compared with the same company pre-implementation, iv) legislation-affected higher emitters have higher levels of voluntary disclosures. These findings are consistent with legitimacy theory, which predicts differential disclosures in circumstances to avoid scrutiny.     

Affiliated firms and financial support: Evidence from Indian business groups

We investigate the functioning of internal capital markets in Indian Business Groups. We document that intragroup loans are an important means of transferring cash across group firms and are typically used to support financially weaker firms. Evidence suggests that an important reason for providing support may be to avoid default by a group firm and consequent negative spillovers to the rest of the group. Consistent with such spillovers, the first bankruptcy in a group is followed by significant drops in external financing, investments and profits of other firms in the group and an increase in their bankruptcy probability.     

Bifurcation analysis of Zellner's Marshallian Macroeconomic Model

The Marshallian Macroeconomic Model in Zellner and Israilevich (2005) provides a novel way to examine sectoral dynamics through the introduction of a dynamic entry/exit equation in addition to the usual demand and supply functions found in models of this class. In this paper we examine the possibility of cyclical behavior in the Marshallian Macroeconomic Model and investigate the existence of a Hopf bifurcation with respect to the parameter in the entry/exit equation.
