Sorting Models in Discrete Choice Fisheries Analysis
Provedor de dados: 31
Autores: Smith,   Martin D.; Zhang,   Junjie.
One of the greatest challenges facing empirical fisheries researchers is to endogenize fishing effort in bioeconomic models in a way that accounts for fleet heterogeneity. Such heterogeneity can manifest in a wide range of both observable and unobservable characteristics of fishing vessels and individual fishermen. Without accounting for heterogeneity, we simply have an incomplete understanding of how pressure on fish resources responds to policy instruments that are available, the states of fish stocks, and exogenous shocks to the system. Largely due to data limitations, the discrete choice fisheries literature has focused on modeling unobserved heterogeneity through random parameters. In this paper, we draw on the industrial organization literature on...

Bayesian Bioeconomics of Marine Reserves
Provedor de dados: 31
Autores: Smith,   Martin D.; Zhang,   Junjie; Coleman,   Felicia C.
We use Bayesian econometric methods to estimate dynamic bioeconomic models of marine reserve formation using simulated data and real data from the Gulf of Mexico reef fish fishery. We test the effects of reserves on fish growth and catchability.

SPATIAL SEARCH IN COMMERCIAL FISHING: A DISCRETE CHOICE DYNAMIC PROGRAMMING APPROACH
Provedor de dados: 31
Autores: Smith,   Martin D.; Provencher,   Bill.
We specify a discrete choice dynamic programming model of commercial fishing participation and location choices. This approach allows us to examine how fishermen collect information about resource abundance and whether their behavior is forward-looking.

Endogenous Fishing Mortality in Life History Models: Relaxing Some Implicit Assumptions
Provedor de dados: 31
Autores: Smith,   Martin D.
Life history models can include a wide range of biological and ecological features that affect exploited fish populations. However, they typically treat fishing mortality as an exogenous parameter. Implicitly, this approach assumes that the supply of fishing effort is perfectly inelastic. That is, the supply curve of effort is vertical. Fishery modelers often run simulations for different values of fishing mortality, but his exercise also assumes vertical supply and simply explores a series of these curves as different scenarios. The seemingly innocuous assumption of vertical supply conflicts with a large body of empirical work on behavior of fishermen and fishing fleets. Economists and fisheries scientists consistently find that fishing behavior is...

Valuing Ecosystem Services with Fishery Rents: A Lumped-Parameter Approach to Hypoxia in the Neuse River Estuary
Provedor de dados: 31
Autores: Smith,   Martin D.; Crowder,   Larry B.
Valuing ecosystem services with microeconomic underpinnings presents challenges because these services typically constitute nonmarket values and contribute to human welfare indirectly through a series of ecological pathways that are dynamic, nonlinear, and difficult to quantify and link to appropriate economic spatial and temporal scales. This paper develops and demonstrates a method to value a portion of ecosystem services when a commercial fishery is dependent on the quality of estuarine habitat. Using a lumped-parameter, dynamic open access bioeconomic model that is spatially explicit and includes predator-prey interactions, this paper quantifies part of the value of improved ecosystem function in the Neuse River Estuary when nutrient pollution is...

SPATIAL BEHAVIOR OF RENEWABLE RESOURCE HARVESTERS: THE CALIFORNIA SEA URCHIN FISHERY
Provedor de dados: 31
Autores: Smith,   Martin D.; Wilen,   James E.
This paper analyzes spatial patterns of exploitation in the California sea urchin fishery.  A Random Utility Model of urchin diver participation and location choice yields a conditional logit specification.  Results demonstrate that diver attributes, location-specific features, and characteristics of individual days are important determinants of harvester choices.

OPEN ACCESS AND MISSING MARKETS IN ARTISANAL FISHING
Provedor de dados: 31
Autores: Liese,   Christopher; Smith,   Martin D.; Kramer,   Randall A.
This paper combines a model of open access fisheries exploitation with a distance-based approach to missing labor and product markets.  The model generates predictions about the circumstances under which exploitation increases or decreases with distance.  An econometric model is estimated with survey data from artisanal fishing households in Minahasa, Indonesia.  The results can be used to assess the impacts of improved transportation infrastructure on fishery exploitation.

ANALYSIS OF A SPATIAL ROTATION PLAN FOR THE TULE LAKE NATIONAL WILDLIFE REFUGE
Provedor de dados: 31
Autores: Smith,   Martin D.; Wilen,   James E.
This paper examines the joint agro-wildfowl regulation of the Tule Lake National Wildlife Refuge in California.  The area is jointly managed by the Bureau of Reclamation for both farming and wildfowl benefits.  Production in both sectors has been declining recently, in farming due to nematode and soil pathogen buildup and in wildfowl production due to climax vegetation choking the lake.  A novel spatial rotation plan has surfaced to solve both problems.  We develop a simple model of the rotation option to identify critical variables and then we estimate some of these using data on lease bids.

RENEWABLE RESOURCE PRODUCTION SURFACES, BIOECONOMIC STEADY STATES, AND SPACE
Provedor de dados: 31
Autores: Smith,   Martin D.
This paper explores production surfaces for a spatially differentiated renewable resource.  By analyzing steady state harvests for a fixed amount of total harvesting effort, the conceptual model evaluates management using protected areas and assesses the importance of assumptions about spatial behavior.  A simulation of marine reserves with Beverton-Holt recruitment is presented.

BREEDING INCENTIVE PROGRAMS AND DEMAND FOR CALIFORNIA THOROUGHBRED RACING: THE TRADEOFF BETWEEN QUANTITY AND QUALITY
Provedor de dados: 31
Autores: Smith,   Martin D.
Both quantity of horses and quality  stimulate demand for horse race gambling.  This paper addresses the potential for a quantity/quality tradeoff  due to breeding incentives for California thoroughbreds.  Econometric analysis is used to assess the demand for quality and quantity of horses, and results suggest the likely net benefit of breeding incentives on the industry at large.

TROPHIC PORTFOLIOS IN MARINE FISHERIES: A STEP TOWARDS ECOSYSTEM MANAGEMENT
Provedor de dados: 31
Autores: Sanchirico,   James N.; Smith,   Martin D.
Marine ecologists warn that humans are "fishing down marine food webs." To explore the economic implications of this phenomenon, this paper applies portfolio theory to aggregate fisheries data. It poses two definitions of a sustainable mean-variance catch frontier. It computes a mean-variance frontier for catch using UNFAO historical fisheries data. Finally, the paper discusses the historical trend in inefficiency.

A BIOECONOMIC MODEL OF SPATIAL POLICY OPTIONS
Provedor de dados: 31
Autores: Smith,   Martin D.; Wilen,   James E.
This paper outlines an empirical bioeconomic model that is spatially explicit.  It combines a metapopulation model of sea urchin biology with a discrete choice econometric analysis of harvester behavior.  Discrete choice results are used to simulate short-term spatial closures in the fishery, and implications for long-term spatial management are discussed.
