Technical efficiency effects of input controls: evidence from Australia's banana prawn fishery

This paper provides the first ex post estimates of the effects of input controls on technical efficiency in a fishery. Using individual vessel data from the northern prawn fishery of Australia for the years 1990–1996 and 1994–2000, stochastic production frontiers are estimated to analyse the efficiency impacts of input controls on engine and vessel size. The results indicate that technical efficiency is increasing in a measure of vessel size and engine capacity that was controlled by the regulator from 1985 to 2001, and decreasing in an unregulated input, gear headrope length. The study shows that fishers have substituted from regulated to unregulated inputs over the period 1990–2000 and technical efficiency has declined coincident with increasing restrictions on vessel size and engine capacity. The decline in technical efficiency indicates that the goal of the regulator to increase economic efficiency has not been realized.     

Banking on the Poor? Branch Location and Nonfarm Rural Development in Bangladesh

The geographic location of banks' branches is used to test whether they are responding to unexploited gains from nonfarm rural development in Bangladesh. The branch locations of Bangladesh's Grameen Bank are compared with those of traditional banks. The potential gains from switching out of farming are measured, allowing for heterogeneity in household characteristics conducive to success in nonfarm activities. It is found that many farmers are poorly equipped for success in nonfarm enterprises. Even so, seemingly feasible but unrealized gains from switching are revealed. Grameen Bank is attracted to areas where those gains favor the poor. Other banks appear to put higher weight on gains to those other than the poor.     

Financial reporting fraud and other forms of misconduct: a multidisciplinary review of the literature

Financial reporting fraud and other forms of financial reporting misconduct are a significant threat to the existence and efficiency of capital markets. This study reviews the literature on financial reporting misconduct from the perspectives of law, accounting, and finance. Our goals are to establish a common language for researchers interested in this line of research, describe the main findings and challenges in these literatures, and provide directions for future research. Although research on financial reporting misconduct faces challenges, those challenges provide significant opportunities to advance the literature, as the answers to many questions on financial reporting misconduct remain unsettled.     

Increase in Risk and its Effects on Welfare and Optimal Policies in a Dynamic Setting: The Case of Global Pollution

This paper studies the effects of an increase in risk on welfare and optimal policies in a stochastic dynamic model of global pollution. In a first step, we focus on the case of a single decision maker, and make use of an approach pioneered by Kimball (2014) for studying the impact of a marginal change in risk in optimal stochastic control models. Using a simple model with only one state variable and one control variable, we show how the optimal carbon tax responds to an increase in risk. It is found that the third derivative of the decay function of the stock of pollution may play a decisive role. In a second step, we investigate the extent to which Kimball’s approach may be extended to the case of stochastic dynamic games. We show how strategic interactions complicate the task of evaluating the effects of an increase in risk. Interestingly, in a dynamic model of the tragedy of the commons, we find that an increase in risk can increase welfare even though all agents are risk averse. The reason is that higher risk can cause agents to be more conservative, and this mitigates the tragedy of the commons.     

Future Inequality in CO2 Emissions and the Impact of Abatement Proposals

This paper analyzes future carbon emissions inequality using a group decomposition of the Gini index. Business-as-usual projections to the year 2100 for 135 countries show inequality in per capita emissions declines slowly. Next, the impact on emissions levels and inequality of the Kyoto Protocol and other abatement proposals for Annex II countries in 2010 are measured, with a focus on the gap-narrowing and reranking effects. Substantial reranking of per capita emissions between Annex II and non-Annex II countries will not occur unless the former reduce their emissions by at least 50% (versus 1990 levels) and the latter continue growing unabated.     

Targeting the poor using ROC curves

This paper compares the performance of targeting indicators to identify the poor. If the ROC curve of one indicator lies above that of another, the first indicator dominates the second for all social welfare functions based on the two types of errors involved in targeting. The method is applied to Bangladesh. Fifteen indicators are used, including location, land ownership, education, occupation, demographics, age, family structure, and housing. The analysis is applied at the national, urban, and rural levels with two poverty lines. Education dominates land ownership in urban areas. The ranking is reversed in most cases in rural areas.
