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.     

Improving inventory management in the retail store: The effectiveness of RFID tagging across product categories

While there is a growing body of evidence that Radio Frequency Identification (RFID) tagging can be effective in improving inventory management in the retail store, retailers have little guidance on best practices for implementation. One important unresolved issue is whether tagging is equally effective across different product categories, and if there is a way to predict which categories are better candidates for deployment. We conduct a field experiment comparing the improvement in inventory record accuracy before and after implementing RFID-enabled adjustments to the inventory management system. We find evidence that the effectiveness of RFID tagging is not homogenous for all products. Reductions in the percentage of stockouts ranged from 21% to 36%, depending on category. Categories that are most likely to see a decrease in stockouts, thanks to RFID, have a greater turnover, greater sales volume, greater product variety, lower item cost, and greater inventory density. We draw inferences for retail supply chains which are considering how best to allocate their resources in the most effective manner.     

The effect of oil supply shocks on US economic activity: What have we learned?

Estimated responses of real oil prices and US gross domestic product (GDP) to oil supply disruptions vary widely. We show that most variation is attributable to differences in identification assumptions and in the model specification. Models that allow for a large short-run price elasticity of oil supply imply a larger response of oil prices and a larger, longer lived contraction in US real GDP. We find that, if we condition on a range of supply elasticity values supported by microeconomic estimates, the differences in the oil price responses diminishes. We also examine the role of lag length, of using pre-1973 data, alternative measures of real economic activity and using the median response function instead of the modal structural model.     

Macroeconomic effects of aggregate accounting conservatism: A cross‐country analysis

This paper examines whether aggregate conditional and unconditional conservatism are associated with economic growth. Prior studies find that conditional conservatism improves contracting efficiency, but that unconditional conservatism has either a neutral or detrimental impact on contracting. We therefore conjecture that country‐level conditional conservatism increases the efficiency of resource allocation in an economy, whereas country‐level unconditional conservatism is not similarly beneficial. Using a cross‐country sample, we construct country‐level estimates of conditional and unconditional conservatism. We find that conditional conservatism is associated with higher level of growth in Gross Domestic Product and Gross Domestic Product per Capita. By contrast, unconditional conservatism shows no or negative association. Our study contributes to the ongoing debate on the desirability of accounting conservatism and also extends the literature on the macroeconomic effects of aggregate financial reporting attributes.     

The Risks and Returns of Brady Bonds in a Portfolio Framework

This paper examines the risks and returns of Brady bonds for the period 1990–1995 in a Modern Portfolio Theory framework. We find: (1) that the realized returns of Brady bonds are lower than the realized returns of other asset classes such as US stocks or US bonds; and (2) Brady bonds exhibit higher volatility compared to the other asset classes. These findings are largely explained by the influence of Mexico's devaluation of the Peso in December 1994. In addition, Mexico's devaluation is found to have had a strong (adverse) contagion effect on the returns on Brady bonds of other countries. The paper also finds that Brady bonds exhibit low correlations with US stocks and bonds markets. Thus, we find that there are potentially positive diversification gains from including Brady bonds in a domestic (US investor's) portfolio.     

Renegotiation in Repeated Games with Side-Payments

We consider repeated games with side-payments: players have an endowment of wealth in each period in which transfers can be made. We show that if endowments are large enough and the common discount factor high enough, then a strongly renegotiation–proof equilibrium (SRP) in the sense of Farrell and Maskin exists. As the discount factor goes to 1, the set of SRP payoffs converges to the set of efficient, individually rational payoffs. These results provide a justification for the efficiency principle when agreements are not enforceable. Journal of Economic Literature Classification Numbers: C73, D23, L14.     

Market forces meet behavioral biases: cost misallocation and irrational pricing

Psychological and experimental evidence, as well as a wealth of anecdotal examples, suggests that firms may confound fixed, sunk, and variable costs, leading to distorted pricing decisions. This article investigates the extent to which market forces and learning eventually eliminate these distortions. We envision firms that experiment with cost methodologies that are consistent with real‐world accounting practices, including ones that confuse the relevance of variable, fixed, and sunk costs to pricing decisions. Firms follow “naive” adaptive learning to adjust prices and reinforcement learning to modify their costing methodologies. Costing and pricing practices that increase profits are reinforced. In some market structures, but not in others, this process of reinforcement causes pricing practices of all firms to systematically depart from standard equilibrium predictions.     

Financial Distress and Bank Lending Relationships

We use a unique data set of bank loans to examine the wealth effects on lead lending banks when their borrowers suffer financial distress. We find a significant negative announcement return for the lead lending bank when a major corporate borrower announces default or bankruptcy. Banks with higher exposure to the distressed firm have larger negative announcement-period returns. The existence of a past lending relationship with the distressed firm results in larger wealth declines for the bank shareholders. Finally, financial distress also has a significant negative effect on borrower's returns.
