Public Research Policy for Today's Agricultural Biotech Research Industry

While the public sector has historically played a very significant role in the direct provision of agricultural research, the appropriate role of government in the future is no longer apparent in a world with intellectual property rights (IPRs) and a concentrated privatized biotech research industry. This study develops a search/imperfect competition framework to examine the public role. The analysis shows that private firms have inadequate incentives to invest in research for varietal improvement relative to the social optimum even with completely enforceable IPRs. A government subsidy on research output can efficiently increase the amount of applied research to the socially optimal point. Government subsidy of the research cost can have the same effect on research and development expenditure. Expanding direct applied public research increases social welfare but cannot achieve a social optimum, as it reduces the already limited incentives for private firms to invest. Finally, in situations where basic research is underprovided, government should address these market failures as part of an optimal research policy. Overall, the analysis suggests that there is a role for public support of applied research, but this role is no longer direct public involvement in applied research where IPRs are well established.     

Urban Sprawl and Farmland Prices

A theoretical model of farmland valuation is developed to explicitly account for three effects of urban sprawl: conversion of farmland to urban uses, effect on agricultural returns, and speculative effect as represented by farmland conversion risk. This model is estimated using county-level data in the continental United States. Evidence is found for all three effects of urban sprawl on farmland values. Counties more accessible to major urban centers have higher net agricultural returns. Subsidiary evidence supports that the latter effect may be attributed to survival of (or conversion to) high-valued agriculture around urban centers.     

Segmentation in the informal credit markets: the case of the Philippines

This paper explains market segmentation that occurs in the Philippine informal credit markets through the matching of borrowers and lenders by their occupational specializations to internalize transaction costs and facilitate economic activity. The regression results support a predictable pattern of matching farmer lenders with borrowers specialized in non-farm activities and trader lenders with borrowers specialized in farming.     

Optimal Commodity Promotion when Downstream Markets are Imperfectly Competitive

We investigate the optimal collection and expenditure of funds for agricultural commodity promotion in markets where the processing and distribution sectors may exhibit oligopoly and/or oligopsony power. The conditions that characterize optimal advertising intensity under perfect competition for funds generated from either per-unit or lump-sum taxes do not, in general, hold when marketing is imperfectly competitive. Simulation analyses show that imperfect competition always reduces farmers' optimal advertising expenditure and that an imperfectly competitive marketing sector may capture half or more of the benefits from the funds that are expended.     

PATH ANALYSIS: AN EXAMPLE

This paper describes the technique of path analysis using data from Scully (1962). Path analysis is a method of decomposing covariances or correlations between two variables in a structural equation model in order to determine how much of this covariance is attributable to a theoretically specified causal effect of one variable on the other. In so far as it allows us to assess the relative importance of different explanatory variables in a more adequate manner than does regression, path analysis is a technique of wide potential applicability to economists and sociologists.     

Tourism and Governance in Small Island Developing States (SIDS): The Case of Zanzibar

Tourism in small island developing states (SIDS) has long been defined in terms of dependency. However, less attention has been paid to the role of the state in SIDS, particularly the extent to which it supports tourism as an agent of development. Therefore, the purpose of this paper is to consider the governance of tourism development in SIDS, specifically the extent to which the state may promote or hinder tourism‐related development. Drawing on research in Zanzibar, it reveals the ways in which poor governance has acted as a barrier to development through tourism, concluding that the state has an unwillingness to support tourism.

Preservation: Planning for the survival of things

Preservation—the immortalisation of living and designed things—is a channel for transmitting messages from the past to the future. Image is all important for conveying the meaning. To be preserved, a thing must have a constituency of supporters and a long-lived institution to serve as trustee: when appreciators of the message are no longer recruited, extinction is at hand. Community ecology, if extended to images, suggests some appropriate preservation policies for societies approaching steady state, eg adding to the total stock of biomass, to diversity, and to useful knowledge, while promoting new organised relationships between man and environment.     

Goal programming: Planning process of tourism organizations

The complex rapidly changing environment faced by tourism organization officials makes tourism planning extremely difficult. Goal programming can aid the tourism planner in appraising the goal attainment potential associated with proposed tourism marketing program alternatives. By changing priorities of goals, budgetary limitations, and organizational constraints, the policy maker can test the effect of changes before they are implemented. By utilizing goal programming, a tourism organization can more systematically evaluate the nature and relative importance of organizational goals, critical constraints affecting the organization and marketing program alternatives.     

In quest of useful models for educational systems

Analytical flow models are examined as a means for describing the performance of an educational system. Enrollment functions based on specified input functions are developed for a single grade for four special cases. A standard form for approximation is introduced and its use described. This leads to the proposition that complex systems can be fabricated of modules defined in terms of these standard approximations. Applications of this approach, and problems expected in its use, are discussed, including the question of quality of the educational process. The paper concludes with some brief comments on measurement and evaluation of performance.
