Technical Efficiency and the Role of Skipper Skill in Artisanal Lake Victoria Fisheries

Submitted by admin on
EfD Authors:

This paper studies technical efficiency and skipper skill (and explores potential proxies), using Tanzanian fishery data for the two major species, Nile perch and dagaa. The relative level of efficiency is high in both fisheries, and several observable variables linked to skipper skill significantly explain the efficiency level. However, given the rapidly depleting fish stocks in Lake Victoria, increased efficiency at the aggregate level is only possible if fishing effort is limited.

What Kinds of Firms Are More Sensitive to Public Disclosure Programs for Pollution Control? The Case of Indonesia’s PROPER Program

Submitted by admin on

Analysis of the differences in firms’ responsiveness to PROPER (Indonesia’s successful public disclosure program for industrial pollution control) showed that foreign-owned firms and firms in densely populated areas were more likely to respond to public environmental ratings. Firms with bad environmental performances felt pressure to improve, but this incentive diminished after the initial abatement steps.

Hamstrung by weak institutions that undermine conventional environmental regulatory tools, policymakers in developing countries are increasingly turning to voluntary approaches. To date, however, there have appeared few evaluations of these policy experiments.

Mad Cows, Terrorism and Junk Food: Should Public Policy Reflect Subjective or Objective Risks?

Submitted by admin on

Empirical evidence suggests that people’s risk-perceptions are often systematically biased. This paper develops a simple framework to analyse public policy when this is the case.

The Benefits and Costs of Informal Sector Pollution Control: Traditional Mexican Brick Kilns

Submitted by Anonymous (not verified) on

In developing countries, the rapid proliferation of informal firms – low-technology unlicensed micro-enterprises – is having significant environmental impacts. Yet environmental management authorities typically ignore such firms.

Environmental Policy and Mill Level Efficiency

Submitted by admin on
EfD Authors:

Understanding relationship between environmental protection and economic development is crucial to form practical environmental policy. At micro level, implementation of environmental regulations often causes production mills adjustment of technology which might leads to change of productive efficiency and cost, which, in turn, determine effort level of mills and even local government in pollution control.

Collective versus Random Fining: An Experimental Study on Controlling Ambient Pollution

Submitted by admin on
EfD Authors:

This paper presents an experimental study of two different pollution compliance games: collective vis-à-vis random fining as a means to regulate non-point pollution. Result suggests the importance of considering subject pool differences in the evaluation of environmental policies by means of experiments, particularly if those policies involve certain forms of management decisions.
