The purpose of this research report is to present an evaluation of advisory service pricing performance in 1995 for corn and soybeans. Specifically, the average price received by a subscriber to an advisory service is calculated for corn and soybean crops harvested in 1995. The average net advisory price across all 25 corn programs is $3.04 per bushel. The range of net advisory prices for corn is quite large, with a minimum of $2.34 per bushel and a maximum of $3.81 per bushel. The average net advisory price across all 25 soybean programs is $6.61 per bushel. As with corn, the range of net advisory prices for soybeans is substantial, with a minimum of $5.75 per bushel and a maximum of $7.92 per bushel.

This paper sets out a framework for estimating household preferences over a broad range of housing and neighborhood characteristics, some of which are determined by the way that households sort in the housing market. This framework brings together the treatment of heterogeneity and selection that has been the focus of the traditional discrete choice literature with a clear strategy for dealing with the correlation of unobserved neighborhood quality with both school quality and neighborhood sociodemographics. We estimate the model using rich data on a large metropolitan area, drawn from a restricted version of the Census. The estimates indicate that, on average, households are willing to pay an additional one percent in house prices - substantially lower...

Contentious debate surrounds allocation of the geostationary orbit and electromagnetic spectrum, two resources used by communications satellites. An extensive economics literature alleges that the nonmarket administrative allocative procedures now in place are highly inefficient, but no research has empirically estimated the welfare loss. This paper develops a conceptual framework and a computerized model to estimate the economic value of the resources, the size and distribution of welfare costs associated with the present regulatory regime, and the potential gains from more market-like allocation.

Allocating scare resources for fire management strategies requires information on the extent of economic losses from bushfires and the efficiency of alternatives. Despite the severity of bushfires, there is no agreed approach in Australia for estimating economic losses from fires nor for evaluating the economic efficiency of alternative suppression strategies. The poster proposes approaches to assess the economic effects of bushfires on local and state economies and sets out models to evaluate the economic efficiency of two key bushfire management strategies: presuppression and suppression. The first model arises from questions concerning the value of pre-suppression (before the fire) fuel reduction activities, and the estimation of an economically optimal...

The CV method estimate the monetary value that specific changes in the provision of goods and services represent for society, which is asked for their Willingness To Pay (WTP) for it, according to their budget and individual preferences, in a survey. The applications of CV are a source of information to important public decision-making. Therefore, it seems to be a desirable objective for a CV study to strive to detect and reduce, as far as possible, the bias affecting the elicited values. In the present work, the starting point bias in an application to the case study of the conservation of the Iberian Lynx in Spain is analyzed. This bias is caused by the potential influence of the bid values offered to the interviewees on their stated preferences. Three...

The dilemma of collective action around water use and management involves solving both the problems of provision and appropriation. Cooperation in the provision can be affected by the rival nature of the appropriation and the asymmetries in the access. We report two field experiments conducted in Colombia and Kenya. The Irrigation Game was used to explore the provision and appropriation decisions under asymmetric or sequential appropriation, complemented with a Voluntary Contribution Mechanism experiment which looks at provision decisions under symmetric appropriation. The overall results were consistent with the patterns of previous studies: the zero contribution hypotheses is rejected whereas the most effective institution to increase cooperation was...

Most terrestrial biological invasions occur in landscapes comprising numerous, independently managed properties. Thus, control of invasion spread generally depends on the choices of many managers, each deciding the extent to control invasions on their property. Here we develop a spatially-explicit, integrated model of invasion spread and human behavior to examine how people’s control choices under laissez-faire affect patterns of invasion spread and the total costs and damages imposed by an invader. We evaluate how characteristics of the bioeconomic and social system, including the extent of cooperation among managers, affect the divergence between socially optimal and private control efforts. We find that system-wide invasion externalities generally...

Farmed animal production has traditionally been a dispersed sector. Biosecurity actions relevant to eradicating infectious diseases are generally non-contractible, and might involve inordinately high transactions costs if they were contractible. If an endemic disease is to be eradicated within a region, synchronized actions need to be taken to reduce incidence below a critical mass so that spread can be contained. Using a global game model of coordination under public and private information concerning the critical mass required, this paper characterizes the success probability in an eradication campaign. As is standard in global games, heterogeneity in private signals can support a unique equilibrium. Partly because of strategic interactions, concentrated...

Food safety shocks can threaten the health of consumers, create havoc within an industry and result in severe losses to producers. Governments often attempt to enhance food safety by mandating standards and inspection of food products to supplement the voluntary efforts by private firms. This paper assesses a form of collective action that falls between typical government mandates and purely private action. The California pistachio industry recently established a U.S. federal marketing order. This order sets quality standards and requires inspection and certification, aiming to reduce the likelihood of dangerous or poor quality pistachios being sold to consumers and to provide some quality assurance to consumers. Simulation results indicate that, across...

Rice and wheat are the two major foodgrains in India and their level of production determines the country self-sufficient. Forecasts on cereals supply range from 250 to over 300 million tones in the country by the year 2020. Mere availability of foodgrains is not a sufficient condition to ensure food security but also necessary that the poor have sufficient means to purchase food. Poor economic access leads to food security and it has been checked by the government mechanism through the operation of Targeted Public Distribution System (TPDS) and foodgrains are distributed at subsidized prices to the people living Below Poverty Line (BPL). It is a safety net to more than 330 million poor and those nutritionally at risk and an important delivery channel with...

On a topic like the environment, communication among scholars from different disciplines in the natural and social sciences is both important and difficult, but such communication has been far from perfect. Economists themselves may have contributed to some rather fundamental misunderstandings about how economists think about the environment, perhaps through our enthusiasm for market solutions, perhaps by neglecting to make explicit all of the necessary qualifications, and perhaps simply by the use of jargon that has specific meaning only to other economists. In this brief essay, we seek to clarify some of these misunderstandings and thus to improve future interdisciplinary communication. We hope that natural scientists and other non-economists will take...

International Environmental Agreements: Emissions trade, safety valves and escape clauses

We explain how the structure of multi-national or multi-regional environmental agreements affect their chance of success. Trade in emissions permits has ambiguous and in some cases surprising effects on both the equilibrium level of abatement, and on the ability to persuade nations or regions to participate in environmental agreements. An escape clause policy and a safety valve policy have essentially the same properties when membership in environmental agreement is pre-determined, but they create markedly different effects on the incentives to join such an agreement. The two policies lead to a qualitative difference in the leverage that a potential member of the agreement exercises on other members.

We modify a canonical participation game used to study International Environmental Agreements (IEA), considering both mixed and pure strategies at the participation stage, and including a prior cost-reducing investment stage. The use of mixed strategies at the participation stage reverses a familiar result and also reverses the policy implication of that result: with mixed strategies, equilibrium participation and welfare is higher in equilibria that involve higher investment.

Investigating Distance Effects on Environmental Values: A Choice Modelling Approach

Concu, Giovanni B..

This paper describes a Choice Modelling experiment set up to investigate the relationship between distance and willingness to pay for environmental quality changes. The issue is important for the estimation and transfer of benefits. The Choice Modelling experiment allows testing distance effects on parameters of environmental attributes that imply different trade-offs between use and non-use values. The sampling procedure is designed to provide a "geographically balanced" sample. Several specifications of the distance covariate are compared and distance effects are shown to take complex shapes. Welfare analysis shows that disregarding distance produces under-estimation of individual and aggregated benefits and losses, seriously hindering the reliability of...

The aim of this paper is to analyse patterns of private individual giving to Cultural Heritage institutions in Italy. Based on the emerging economic literature on pro-social behavior, we carried out a Contingent Valuation survey to assess individuals’ willingness to donate to museums and heritage organizations according to different conditions and set of incentives. Our findings reveal that intrinsic motivations and accountability of the recipient institutions may be more effective drivers for eliciting charitable giving than the usually proposed fiscal incentives. The results provide avenues for future empirical research and policy suggestions for fund raising cultural institutions.

Traditional applications of benefit-cost analysis make use of what we refer to as the "damage function and discounting" (or DFD) approach. This approach is well-suited to the analysis of projects for which the principal benefits and costs occur within the next thirty to forty years, say. However, for projects with significant intergenerational consequences--i.e., impacts that do not arise for hundreds of years or more--the DFD approach becomes almost intractable. We propose an alternative conception of benefit-cost analysis for intergenerational decision-making--the mock referendum--that is: (i) arguably more consistent with the tenets of modern welfare economics; (ii) more amenable to the analysis of long-term projects or policies; and (iii) consistent...

The relationship between norms, self-sanctioning, and people’s decisions about contributing to public goods is complex and often misunderstood in the public goods literature. We develop a model in which individuals hold an injunctive norm indicating how much they believe one should contribute to the public good. From the model we derive the following testable hypotheses: an increase in one’s perception of the norm level of contribution to the public good (1) induces negative self-sanctioning and (2) will lead one to contribute more to the public good, and (3) that contributing to the public good induces positive self-sanctioning. To test these hypotheses, we elicit stated preferences for contributions to an organization which offsets carbon emissions...

In customary international and public law, “takings” resulting from regulations designed to protect the public good are generally excluded from compensation rules; this exclusion is known as a police powers carve-out (PPCO). Increasingly, this PPCO is being challenged, particularly in international investment law. This paper analyzes the efficiency properties of a PPCO in a model with endogenous regulation, investment and entry. We design a one-parameter family of carve-out/compensation schemes that induce efficient regulation and firm level investment even when the regulator suffers fiscal illusion and the social benefit from regulation is private information to the regulator. We show that offering a carve-out reduces the subsidy to risky industry...
