ANALYZING THE EFFECT OF CHANGING FEED-BEEF PRICE RELATIONSHIPS ON BEEF PRODUCTION MANAGEMENT STRATEGIES IN HAWAII:  A DYNAMIC PROGRAMMING APPROACH
Provedor de dados: 31
Autores: van Poollen,   H. Walter; Leung,   PingSun.
A dynamic programming approach was used to evaluate the effect of changing the feed input to product price relationship on the beef production management decision process.  The dynamic programming model consists of nine submodels describing and analyzing the time-dependent beef production management decision process.  The model incorporates biological functions and economic principles.  Results clearly showed the importance of the feed-beef price relationships in management decision making.  Optimal beef production management strategies were generally consistent with beef production management practices followed in Hawaii under those feed-beef price relationships.

Do Fishermen Have Different Attitudes Toward Risk? An Application of Prospect Theory to the Study of Vietnamese Fishermen
Provedor de dados: 31
Autores: Nguyen,   Quang; Leung,   PingSun.
Field experiment and household survey data are combined to investigate whether working in a risky occupation such as fishing makes fishermen have different risk preferences than individuals in other occupations. Prospect theory is utilized as the main analytical framework and a structural model approach is developed to simultaneously correlate the parameters of the utility function under prospect theory with other socioeconomic variables. The key finding is that working in fishing makes economic agents less risk averse than others. Fishermen also tend to be less sensitive to probability weighting changes in the experiment. It is possible that fishermen have adapted to their unique environment by using specific heuristics for decision making under...

PERFORMANCE MEASUREMENT OF HAWAII STATE PUBLIC LIBRARIES: AN APPLICATION OF DATA ENVELOPMENT ANALYSIS (DEA)
Provedor de dados: 31
Autores: Sharma,   Khem R.; Leung,   PingSun; Zane,   Lynn.
In view of continuing economic stagnation and consequent budgetary constraints facing the state, Hawaii public libraries have been concerned with their operational efficiency and library managers have been seeking better methods in allocating limited resources among the libraries. This paper employed data envelopment analysis (DEA) technique to assess the performance and resource utilization efficiency of 47 public libraries in Hawaii. Three output measures-circulation, reader visits, and reference transactions and four input categories- collection, library staff, days open, and nonpersonal expenditures were used in the analysis. For fiscal year 1996/97, the estimated technical efficiency scores for Hawaii State public library branches ranged from 0.45 to...

Production Performance Indicators with Externalities: Environmentally-Adjusted Productivity and Efficiency Indicators of a Sample of Semi-Intensive Shrimp Farms in Mexico
Provedor de dados: 31
Autores: Martinez-Cordero,   Francisco Javier; Leung,   PingSun.
Sustainability in operations is a key consideration when discussing aquaculture’s current and future role in providing food and increasing coastal and rural employment and incomes, among other social benefits.  An important problem from the economics point of view is how the economics point of view is how the externalities generated by aquaculture and those that the industry suffers are internalized.  This paper extends the analysis reported in Martinez-Cordero and leung (2004) for a group of semi-intensive shrimp farms in Mexico.  Modifications to the traditional Total Factor Productivity (TFP) and Technical Efficiency (TE) indicators are carried out in order to incorporate in the evaluation the environmental effects of aquacultural activities.  In a...

A MARKET EXAMPLE AND ECONOMIC EVALUATION OF INFORMATION AND PRICE UNCERTAINTY
Provedor de dados: 31
Autores: Nakamoto,   Stuart T.; Halloran,   John M.; Yanagida,   John F.; Leung,   PingSun.
In Hawaii, marketing and production conditions have led to shrinking market shares for local farm produce. The primary limiting factor to maintaining and expanding the market share of Hawaii-grown produce is inconsistent and unreliable supply, compounded by inadequate market coordination.

Choice of Remuneration Regime in Fisheries: The Case of Hawaii’s Longline Fisheries
Provedor de dados: 31
Autores: Nguyen,   Quang; Leung,   PingSun.
One of the most prominent features of remuneration in Hawaii’s longline fisheries industry has been the norm of share contract regimes. This paper investigates whether the use of the share contract regime is positively correlated to increased economic returns. The principal-agent framework is applied to develop a theoretical model for the remuneration choice. Empirical estimation is conducted using a switching regression model that accounts for the effects of certain vessel characteristics on revenue, depending on remuneration regime used (i.e., share contract or flat wage), as well as the potential selection bias in the vessels’ contractual choice. Key findings from counterfactual simulations indicate: (a) a negative selection related to choosing share...
