How Do Public Disclosure Pollution Control Programs Work? Evidence from Indonesia AgEcon
Afsah, Shakeb; Blackman, Allen; Ratunanda, Damayanti.
Although a growing body of evidence suggests that publicly disclosing information about plants' environmental performance can motivate emissions reductions, this phenomenon remains poorly understood. To help fill this gap, this paper presents original data from a survey of plants participating in the Program for Pollution Control, Evaluation and Rating (PROPER), Indonesia's widely-acclaimed public disclosure program. These data suggest that a key means by which PROPER spurs abatement is improving factory managers' information about their own plants' emissions and abatement opportunities. This finding contrasts with the prevailing view in the literature that public disclosure enhances pressures to abate placed on firms by external agents such as community...

The Next Generation of Market-Based Environment Policies AgEcon
Stavins, Robert N.; Whitehead, Bradley W..
We examine what will be required if market-based environmental policy instruments are to become a major force in U.S. environmental policy. We define market-based instruments, and specify five categories: pollution charges; tradable permits; deposit refund systems; reducing market barriers; and eliminating government subsidies. We review major U.S. applications, including: EPA's emissions trading program; the leaded gasoline phasedown; water quality permit trading; CFC trading; SO2 allowance trading; and the RECLAIM program. We assess the U.S. experience in terms of the relatively limited use of these instruments and in terms of the mixed record of performance of implemented instruments. We ask how the next generation of market-based instruments can be...

The Fragility of Social Capital AgEcon
Antoci, Angelo; Sabatini, Fabio; Sodini, Mauro.
This paper addresses two hot topics of the contemporary debate, social capital and economic growth. Our theoretical analysis sheds light on decisive but so far neglected issues: how does social capital accumulate over time? Which is the relationship between social capital, technical progress and economic growth in the long run? The analysis shows that the economy may be attracted by alternative steady states, depending on the initial social capital endowments and cultural exogenous parameters representing the relevance of social interaction and trust in well-being and production. When material consumption and relational goods are substitutable, the choice to devote more and more time to private activities may lead the economy to a “social poverty trap”,...

Rice Consumption in the United States: New Evidence from Food Consumption Surveys AgEcon
Batres-Marquez, S. Patricia; Jensen, Helen H..
Evidence from recent U.S. food consumption surveys provides new information on the distribution of rice consumption, the characteristics of rice consumers, and the diets of people who consume rice. Recently available data from nationally representative surveys of food consumed by individuals in the United States allowed comparison of consumption today (2001-02) with consumption in the mid-1990s. Data come from the Continuing Survey of Food Intakes by Individuals (1994-96) and the National Health and Nutrition Examination Survey (2001-02). Rice is consumed by a significant portion of the U.S. adult population. In 2001-02, over 18 percent (18.2 percent) of adults reported eating at least half a serving of white or brown rice in one day of observed intake....

The Future of Securities Regulation AgEcon
Luigi, Zingales.
The U.S. system of security law was designed more than 70 years ago to regain investors’ trust after a major financial crisis. Today we face a similar problem. But while in the 1930s the prevailing perception was that investors had been defrauded by offerings of dubious quality securities, in the new millennium, investors’ perception is that they have been defrauded by managers who are not accountable to anyone. For this reason, I propose a series of reforms that center around corporate governance, while shifting the focus from the protection of unsophisticated investors in the purchasing of new securities issues to the investment in mutual funds, pension funds, and other forms of asset management.

REFORMING OUTDATED FENCE LAW PROVISIONS: GOOD FENCES MAKE GOOD NEIGHBORS ONLY IF THEY ARE FAIR AgEcon
Centner, Terence J..
Conflicts between persons engaged in animal husbandry and their neighbors have given legislative bodies many challenges in responding to competing equities. One set of rules has concerned the enclosure of domestic livestock, and legislative bodies have adopted assorted fence rules to resolve competing interests associated with grazing by domestic animals. Alternative fence-out legislation still exists in some jurisdictions for open range and very rural areas. Under fence-out legislation, ranchers do not have to build fences to confine their animals; rather, persons who want to keep out stray livestock have the burden of putting up a fence. Economists have given considerable attention to the externalities posed by livestock and the economic...

MINNESOTA AGRICULTURAL GROWTH, 1880-1970 AgEcon
Fitzharris, Joseph C..
The growth of Minnesota's agricultural sector, 1880-1970, was quite considerable. More important than providing a history, this study provides the necessary background for examination of the agricultural research system of Minnesota. Here, the record will be detailed. This study examines, in turn, the record of: output and production; the factors of production; relative output and input prices changes; and the structural changes in the sector

The Case for Intensity Targets AgEcon
Pizer, William A..
While the rest of the world has pursued absolute emissions limits for greenhouse gases, the Bush administration has proposed an alternative policy formulation based, among other things, on reducing emissions intensity-that is, emissions per dollar of real gross domestic product. Critics of this formulation have denounced the general idea of an intensity-based emissions target, along with its voluntary nature and weak targets. This raises the question of whether intensity-based emissions limits, distinct from the other features of the Bush initiative, offer a useful alternative to absolute emissions limits. This paper makes the case that they do, based on how emissions targets are framed. The argument draws on four key observations: greenhouse gas emissions...

Expert opinion and cuisine reputation in the market for restaurant meals AgEcon
Fogarty, James Joseph.
As food is an experience good, the market for restaurant meals is a market where the cost of acquiring information regarding quality is relatively high. In such markets consumers often turn to reputation measures to guide purchase decisions. As Australia does not have a longstanding cuisine style of its own, and given Australia has been open to substantial immigration inflows since federation, it represents an especially appropriate market to study regarding the impact of individual restaurant reputation and collective cuisine reputation on meal prices. The following study uses the hedonic price approach to investigate the implicit price of individual reputation indicators, cuisine type reputation indicators, and other objective indicators in the market...

A note on the performance measure of conservation auctions AgEcon
Latacz-Lohmann, Uwe; Schilizzi, Steven.
We argue that previous assessments of discriminatory-price conservation auctions may have systematically overestimated their performance relative to uniform-payment schemes due to an inappropriate counterfactual comparison. We demonstrate that the cost curve (and not the bid curve) is the relevant supply curve when a uniform payment is offered and provide a theoretically rigorous counterfactual based on that insight. We estimate that the performance of BushTender may have been overrated by more than 50%.

RURAL LAND VALUES AND TENURE ARRANGEMENTS IN LOUISIANA AgEcon
Kennedy, Gary A.; Henning, Steven A.; Vandeveer, Lonnie R..
This report presents the results from the first annual Louisiana Rural Land Market Survey. The survey was designed to collect detailed information from rural real estate professionals regarding market conditions in their areas. Results of this study suggest that land values vary by area of the state and the primary commodity grown on the tract. Substantial variation in land value within areas and by parish suggests a number of factors affect rural land values and markets. Further research will be designed to measure the effects of these various factors on rural real estate markets.

The Structural Estimation of Principal-Agent Models by Least Squares: Evidence from Land Tenancy in Madagascar AgEcon
Brown, Zachary S.; Bellemare, Marc F..
We develop a method to structurally estimate principal-agent models by ordinary least squares (OLS). We set up a general principal-agent model which explicitly incorporates the wealth levels of each party and the opportunity cost to the agent of entering the contract. This yields an optimal contract that is linearized by way of an Nth order Taylor approximation. This in turn imposes N(3N-1)/2 restrictions on the parameters and yields an empirical test of the canonical principal-agent model. In the application, we consider the case where N = 2 and apply our method to a sample of land tenancy contracts in rural Madagascar. Empirical tests lead to consistent failure to reject the hypotheses derived from our structural model, which lends support to our...

DISCRIMINATION BY FORMAL LENDERS IN SOUTH AFRICA AgEcon
Schreiner, Mark; Graham, Douglas H.; Vink, Nick; Coetzee, Gerhard K..
Censored (Tobit) regression is used to estimate the effects of race, location of residence, and sex of the household head on formal debt held by South African households. The magnitude of the effects suggests that lenders discriminate and that formal financial markets could be improved even without technical innovation.

Imperfections in the Economics of Public Policy, Imperfections in Markets, and Climate Change AgEcon
Stern, Nicholas.
n the last twenty years economics has created much of lasting value and real potential: it has been a very fertile period. But economics has also suffered from what I shall term „collective amnesia‟ covering whole areas of public policy. And on policy and the role of government it has, embarrassingly in my view, swayed with the political winds to the detriment of both our profession and to outcomes. Both the amnesia and the political bending have contributed to the economic crisis of the last year or two and to hostility towards the profession. My purpose here is first to lament the amnesia on theories of public policy in imperfect economies, in short the subject of public economics, to describe the bending of public policy analysis to political vogue, and...

EQUILIBRIUM AND EFFICIENT LAND-USE ARRANGEMENTS UNDER SPATIAL EXTERNALITY ON A LATTICE AgEcon
Saak, Alexander E..
Many cases of externalities in agricultural production, such as pesticide drift, cross-pollination, and offensive odors, are attributable to the incompatibility of neighboring land uses and exhibit distance dependence. We characterize equilibrium spatial patterns of externality-generating and -receiving land uses on a two-dimensional lattice with noncooperative, profit-maximizing producers. In equilibrium, generators or recipients form one or more neighborhoods with certain geometric properties, depending on how an externality dissipates with distance and whether there is an externality generated outside the region's boundaries. Efficient land-use arrangements maximize social welfare subject to the implementability constraints stipulating that no...
