Overfishing threatens coral reefs worldwide, yet there is no reliable estimate on the number of reef fishers globally. We address this data gap by quantifying the number of reef fishers on a global scale, using two approaches - the first estimates reef fishers as a proportion of the total number...

Fisheries management must manage people in order to manage fish. In this sense, understanding fishing behavior is the cornerstone of effective fisheries policy. However, the latency of fish stocks is a major obstacle in empirical studies. This paper addresses this challenge by deriving a stock...

The article analyses the indirect effects of informal insurance on open-access renewable resource use. It is based on a field study of two neighbouring island fisheries in the Ha'apai region in the Kingdom of Tonga. On one island, 'Uiha, the fishery is under greater stress and fishers have...

U.S. federal law calls for an end to overfishing, but measuring overfishing requires knowledge of bioeconomic parameters. Using micro-level economic data from the commercial fishery, this paper proposes a two-stage approach to estimate these parameters for a generalized fishery model. In the...

Structural models can assess the effectiveness of fishery management prospectively and retrospectively. However, when only fishery-dependent data are available, structural econometric models are highly nonlinear in the parameters, and maximum likelihood and other extremum-based estimators can...

The rise of ecosystem management as an approach to renewable resource policy increases the demand for empirical bioeconomics. This paper provides a working definition of bioeconometrics and a taxonomy of model types. A bioeconometric model is a structural model that econometrically estimates one...

In this paper we introduce inverse demand systems that include quadratic scale terms. These systems are similar to regular quadratic demand systems introduced by Howe, Pollack, and Wales. A unique feature of these specifications is that they maintain linear scale curves as a special case. For...

The impact of uncertainty on firms' investment outlays is subject to an ongoing debate. Theory identifies several channels. Irreversibility, financing constraints and risk aversion make a negative relationship between uncertainty and investment likely. On the other hand, the ability of firms to...
