Determinants of Government Aid to Katrina Survivors: Evidence from Survey Data

We analyze survey data from Mississippi coastal communities where Katrina made its final landfall. Logistic regressions indicate that government aid is helpful in dealing with one- to two-month economic disruption and long-term rebuilding but is less helpful with regard to short-term rebuilding and mitigating longer-term disruption. Our analysis (including a basic risk assessment) finds evidence that individuals receiving government aid and/or having a disability predisaster are likely to incur severe economic hardship postdisaster and that individuals with greater predisaster economic and/or social network capital seem to be less at risk. Our results underscore the importance of housing in the resumption of basic economic activity.     

Mending the family tree a reconciliation of the linearization and levels schools of AGE modelling

This paper offers a critical comparison between the North American levels school of applied general equilibrium modelling, and the Norwegian/Australian school of linearizers. The paper develops both the levels and linearized representations of a neoclassical multiregion trade model. This is used as a vehicle for focusing attention on similarities and differences between the two schools. The main conclusions are: (i) that both the levels and linearized versions of non-linear AGE model offer a valid starting point for obtaining accurate solutions to the non-linear equilibrium problem; (ii) when update formulae are not employed, linearized representations are particularly prone to erroneous welfare conclusions; (iii) the levels representation offers a more natural starting point for expressing accounting conditions, whereas behavioural relationships are relatively more easily expressed in a linearized representation. Recent software developments now make both approaches to the representation and solution of non-linear AGE models convenient to implement. Thus the choice of which approach to use will depend on the special needs and preferences of the economist implementing the model. The two traditions of AGE modelling have a great deal in common and both would benefit from greater cooperation.     

The road to cooperative supply‐chain environmental management: trust and uncertainty among pro‐active firms

The pressures on firms to improve their environmental performance have caused them to look outside their boundaries towards their supply chains. In such approaches, firms work with vendors to develop the environmental profile of supplied materials (for example) by reducing materials' toxicity or the amount of packaging used. While large firms can mandate that their suppliers comply with such initiatives, more cooperative approaches are generally likely to be more fruitful. This article presents the results from an exploratory, two phase study of the conditions under which firms engage in cooperative supply‐chain environmental management. First, the authors conducted interviews with 14 leading‐edge firms. In the second phase, the authors conducted a theoretical‐sample survey to examine a model of the antecedents of cooperative supply‐chain environmental management. The results suggest that inter‐firm trust, uncertainty and pro‐active environmental management most directly affect the extent to which firms engage in cooperative supply‐chain environmental management.

Domestic-Foreign Interest Rate Differentials: Near Unit Roots and Symmetric Threshold Models

This paper investigates the near unit root behavior of interest rate differentials across countries using a symmetric Band-TAR model that allows for a heteroscedastic error process. We find that the time series properties of monthly short-term interest differentials over the period 1974–2005 between the United States and Canada, France, Germany, Japan, and the United Kingdom can be characterized by a symmetric Band-TAR process, which can explain its (near) unit root behavior reported in the extant literature. Results significantly reject a linear model in favor of the alternative hypothesis of a two-regime symmetric threshold model that exhibits significantly greater persistence within the threshold bands than when outside the threshold bands.     

The price elasticity of the supply of single-family detached urban housing

Past attempts to estimate the price elasticity of the supply of housing have erred by using aggregate data. Many houses are built in areas where the volume of residential construction is low. Consequently, the influence of observations from higher-volume areas where costs may be higher is diminished. This problem is eliminated by using cross-sectional data from 61 different American urban areas, for a total of 223 observations from 1976 to 1981, to estimate a translog cost function for housing. The supply elasticity is found to be infinite.     

Employee perceptions and their influence on training effectiveness

Studies of the benefits of human resource development (HRD) for organisations have assumed a direct connection between training strategy and a hierarchy of performance outcomes: learning, behavioural change and performance improvement. The influence of workplace practices and employees' experiences on training effectiveness has received little attention. This study investigates evaluation strategies designed to elicit greater training effectiveness, and explores the influence of trainees' perceptions and work environment factors on this. Drawing on detailed case study findings, the authors highlight the importance of management practices, trainees' perceptions of the work environment and systems of reward in explaining behaviour change after training.     

Do Federal Home Loan Bank membership and advances increase bank risk-taking?

Since the early 1990s, commercial banks have turned to Federal Home Loan Bank (FHLBank) advances to plug the gap between loan and deposit growth. Is this trend worrisome? On the one hand, advances implicitly encourage risk by insulating borrowers from market discipline. On the other, advances give borrowers greater flexibility to managing interest rate and liquidity risk. And access to FHLBank funding encourages members to reshape their balance sheets in ways that could lower credit risk. Using quarterly financial and supervisory data for banks from 1992 to 2005, we assess the effect of FHLBank membership and advances on risk. The evidence suggests liquidity and leverage risks rose modestly, but interest-rate risk declined somewhat. Credit risk and overall failure risk were largely unaffected. Although the evidence suggest FHLBank membership and advances have had, at best, only a modest impact on bank risk, we caution that our sample period constitutes one observation and that moral hazard could be pronounced if leverage ratios revert to historical norms.
