Determinants of Agricultural Output: Degree Days, Yields and Implications for Climate Change AgEcon
Schlenker, Wolfram; Hanemann, W. Michael; Fisher, Anthony C..
We link farmland values to climatic, soil, and socioeconomic variables for counties east of the 100th meridian, the historic boundary of agriculture not primarily dependent on irrigation. Degree days, a non-linear transformation of the climatic variables suggested by agronomic experiments as more relevant to crop yield gives an improved fit and increased robustness. Estimated coefficients are consistent with the experimental results. The model is employed to estimate the potential impacts on farmland values for a range of recent warming scenarios. The predictions are very robust and more than 75% of the counties in our sample show a statistically significant effect, ranging from moderate gains to large losses, with losses in the aggregate that can become...

Fishery Management Under Multiple Uncertainty AgEcon
Sethi, Gautam; Costello, Christopher; Fisher, Anthony C.; Hanemann, W. Michael; Karp, Larry S..
Among others who point to environmental variability and managerial uncertainty as causes of fishery collapse, Roughgarden and Smith (1996) argue that three sources of uncertainty are important for fisheries management: variability in fish dynamics, inaccurate stock size estimates, and inaccurate implementation of harvest quotas. We develop a bioeconomic model with these three sources of uncertainty, and solve for optimal escapement based on measurements of fish stock in a discrete-time model. Among other results we find: (1) when uncertainties are high, we generally reject the constant-escapement rule advocated in much of the existing literature, (2) inaccurate stock estimation affects policy in a fundamentally different way than the other sources of...

Global Warming, Endogenous Risk and Irreversibility AgEcon
Fisher, Anthony C.; Narain, Urvashi.
This paper develops two-period analytical and numerical models to study the question: given a stock of greenhouse gases that poses a risk of future damages of unknown magnitude, and the possibility of learning about damages, how do sunk abatement capital and a nondegradable stock of greenhouse gases affect optimal first-period investment? We show that both affect investment, the former negatively and the latter positively. Additionally, endogenous risk--the risk of damages dependent on the stock of gases-- results in an increase in optimal investment for any level of capital "sunkness" or greenhouse gas degradability. Quantitatively, though, the effect of sunk capital is much stronger than the effect of greenhouse gas irreversibility or that of...

Nonconvexity, efficiency and equilibrium in exhaustible resource depletion AgEcon
Fisher, Anthony C.; Karp, Larry S..
We reconsider the problem of inefficiency and nonexistence of a competitive equilibrium in exhaustible resource markets where extraction costs are nonconvex. The existence of a backstop technology (which induces a flat portion of the industry demand curve) restores both existence and efficiency, provided that the backstop price is sufficiently low. If firms face even a small amount of uncertainty regarding their rivals' stocks, a backstop technology is sufficient to restore existence of competitive equilibrium, even if the backstop price is very high. In this case, however, the competitive equilibrium is not efficient.

On the existence and optimality of competitive equilibria in nonrenewable resource industries AgEcon
Fisher, Anthony C.; Karp, Larry S..
If average costs in a nonrenewable resource industry are U-shaped, a competitive equilibrium may not be optimal and, indeed, may not exist. Although the differential equation that describes the change in the rate of extraction is the same for planner and firm, the boundary conditions obtained from the transversality conditions for the respective problems (for planner and firm) will not, in general, be the same. If costs are convex, or if there exists a backstop technology which can produce the resource services at sufficiently low cost, the boundary conditions are, however, the same.

PRICE AND NON-PRICE INFLUENCES ON WATER CONSERVATION: AN ECONOMETRIC MODEL OF AGGREGATE DEMAND UNDER NONLINEAR BUDGET CONSTRAINT AgEcon
Corral, Leonardo; Fisher, Anthony C.; Hatch, Nile W..
We study the influence of prices and non-price conservation programs on water consumption and conservation behavior during a drought in the San Francisco Bay Area. The empirical results show that pricing can be effective in reducing water consumption. Use restrictions and landscaping audits are also effective in inducing conservation from consumers.

Price and Non-Price Influences on Water Conservation: An Econometric Model of Aggregate Demand under Nonlinear Budget Constraint AgEcon
Corral, Leonardo; Fisher, Anthony C.; Hatch, Nile W..
This paper develops a model of residential water demand under a nonlinear budget constraint. The theoretical model for an individual consumer is adapted to yield an aggregate model that preserves the structure of the individual demand function, and that can be used with aggregate (water district level) data. The model is used to study the influence of pricing and non-price conservation programs on consumption and conservation behavior in three water districts in the San Francisco Bay Area, over a 10-year period that includes both drought and normal years. Empirical results show that pricing can be effective in reducing water consumption, particularly during the annual dry season, and during longer drought episodes. The effect is mitigated when non-price...

The Temporal Resolution of Uncertainty and the Irreversibility Effect AgEcon
Narain, Urvashi; Hanemann, W. Michael; Fisher, Anthony C..
We define the irreversibility effect and demonstrate its importance in problems involving investment decisions under uncertainty. We establish several analytical and numerical results that suggest both that the effect holds more widely than generally recognized, and that an existing result (Epstein's Theorem) giving a sufficient condition for determining whether the effect holds can be applied more widely than previously indicated, in particular to problems involving intertemporally nonseparable benefit functions. We further show that a low elasticity of intertemporal substitution will however result in failure of the effect, but that the effect will hold if the value of information increases in the degree of flexibility.

Water supply options for the East Bay municipal utility district : a critical analysis AgEcon
Fisher, Anthony C..
The two main objectives of the East Bay Municipal Utility District (EBMUD) water supply management program are to cope with a failure of the aqueducts in the Delta due to earthquake and flood damage and to mitigate periodic shortages. EBMUD emphasizes construction of additional terminal storage, specifically development of a reservoir in Buckhorn Canyon, to meet both objectives. Better alternatives--cheaper and less environmentally damaging--are (to cope with failure) use of existing terminal storage and interties, along with an eventual phased construction of secure aqueducts in tne Delta, and (to mitigate shortages) purchase of high quality Mokelumne River water from the nearby Woodbridge Irrigation District, along with sharply rising block rates to...
