Deposit Collectors AgEcon
Ashraf, Nava; Karlan, Dean S.; Yin, Wesley.
Informal lending and savings institutions exist around the world, and often include regular door-to-door deposit collection of cash. Some banks have adopted similar services in order to expand access to banking services in areas that lack physical branches. Using a randomized control trial, we investigate determinants of participation in a deposit collection service and evaluate the impact of offering the service for micro-savers of a rural bank in the Philippines. Of 137 individuals offered the service in the treatment group, 38 agreed to sign-up, and 20 regularly used the service. Take-up is predicted by distance to the bank (a measure of transaction costs of depositing without the service) as well as being married (a suggestion that household bargaining...

Elasticities of Demand for Consumer Credit AgEcon
Karlan, Dean S.; Zinman, Jonathan.
The price elasticity of demand for credit has major implications for macroeconomics, finance, and development. We present estimates of this parameter derived from a randomized trial. The experiment was implemented by a consumer microfinance lender in South Africa and identifies demand curves that, while downward-sloping with respect to price, are flatter than recent estimates in both developing and developed countries throughout most of a wide price range. However, demand becomes highly price sensitive at higher-than-normal rates. We discuss several interpretations of this kink and present some related evidence. We also find that loan size is far more responsive to changes in loan maturity than to changes in interest rate. This pattern is more pronounced...

Farm-Level Evidence on the Sustainable Growth Paradigm from Grain and Livestock Farms AgEcon
Escalante, Cesar L.; Turvey, Calum G.; Barry, Peter J..
This study uses the sustainable growth rate model to investigate, measure, and analyze sustainable growth rates and trends for Illinois farmers. Results of farm-level econometric analyses indicate the relevance of the sustainable growth paradigm in explaining most farm financial decisions made each year. Grain farms have shown a greater tendency to balance growth through adjustments in production efficiencies while livestock farms rely more on financial leveraging strategies. In general, our results have shown that the farm sector has adapted to positive or negative sustainable growth challenges consistent with the Higgins' model and that, from an equilibrium point of view, countercyclical measures of the sustainable growth challenge indicate that there...

Fixed Instruments to Cope with Stock Externalities An Experimental Evaluation AgEcon
Giordana, Gaston A.; Willinger, Marc.
We evaluate the effectiveness of non optimal and temporally inconsistent incentive policies for regulating the exploitation of a renewable common-pool resource. The corresponding game is an N-person discrete-time deterministic dynamic game of T periods fixed duration. Three policy instruments with parameters that remain constant for the whole horizon are evaluated: a pigouvian tax (flat tax), an ambient tax (ambient flat tax) and an instrument combining the two previous ones (mixed flat instrument). We test in the lab the predictions of the model solved for 3 distinct behavioural assumptions: (a) sub-game perfection, (b) myopic behaviour, and (c) joint payoff maximization. We find that subjects behave myopically in the unregulated situation, which agrees...

Hyperbolic discounting in analyzing investment in groundwater irrigation in India AgEcon
Chandrakanth, Mysore G.; Rashmi, N.; Chandrashekar, H.; Nagaraj, N..
Researchers are often confronted with the choice of discount rate as well as the method of discounting for estimating the amortized cost of long-term investment in agriculture including groundwater irrigation. The obvious choice is to use the opportunity cost of capital, which is the prevailing interest rate of around 9 percent (compounded – exponential basis), charged on longterm agriculture loans. However, using the ‘exponential’ basis does not provide a realistic amortized cost of irrigation as it over estimates the value of investment due to ‘exponential’ basis as demonstrated above. In order to obtain an empirical estimate of this interest rate, using field data from farmers three dry agro-climatic zones of Karnataka (Shamsundar (1996), Sripadmini...

Impact of Risk and Time Preferences on Responses to Forest Tenure Land Reform: Empirical Evidence from Fujian, China AgEcon
Sullivan, Karen A.; Uchida, Emi; Xu, Jintao.
This research examines the effect of risk and time preferences on forest management responses to forest tenure land reforms in Fujian, China that began in 2002. The different extent of the reform and its different timing across regions provide a natural experiment to test how time and risk preferences affect a households’ forest investment response to the reform. Empirically, we combine original field experiment data on time and risk preferences collected among 103 households with an original panel survey data set collected among the same 103 households, which contains data for three years: 2000 (before the reform), 2005 and 2008 (after the reform) in a difference-in-differences framework. We examine three measures of forest management activity, including:...

Intertemporal Risk Management Decisions of Farmers under Preference, Market, and Policy Dynamics AgEcon
Wang, H. Holly; Du, Wen.
This paper adapts a generalized expected utility (GEU) maximization model (Epstein and Zin, 1989 and 1991) to examine the intertemporal risk management of wheat producers in the Pacific Northwest. Optimization results based on simulated data indicate the feasibility of the GEU optimization as a modeling framework. It further extends the GEU model by incorporating a welfare measure, the certainty equivalent, to investigate the impacts of U.S. government programs and market institutions on farmers' risk management decisions and welfare. A comparison between the GEU and other expected utility models further implies GEU has the advantage of specifying farmers' intertemporal preferences separately and completely. Impact analysis results imply that farmers'...

Investment Spikes in Dutch Horticulture: An Analysis at Firm and Aggregate Firm Level Over the Period 1975-1999 AgEcon
Goncharova, Natalia V.; Oskam, Arie J..
An intermittent and lumpy pattern of investments is observed in the Dutch horticulture sector: only 16.5% of firms experience of investment spike, but they account for 67.7% of total investment. The objective of this paper is to examine the impact of time-varying and time-invariant variables on the probability of observing an investment spieke. This paper investigates the spells between investment spikes in a discrete-time proportional hazard framework. Duration models were estimated on two data sets: on an unbalanced panel and on a grouped into 10 groups data of Dutch glasshouse firms over the period 1975-1999. Different specifications of the model were estimated. Theoretically based model can sufficiently explain the occurrence of investment spikes. Both...

Nuclear versus Coal plus CCS: A Comparison of Two Competitive Base-load Climate Control Options AgEcon
Tavoni, Massimo; van der Zwaan, Bob.
In this paper we analyze the relative importance and mutual behavior of two competing base-load electricity generation options that each are capable of contributing significantly to the abatement of global CO2 emissions: nuclear energy and coal-based power production complemented with CO2 capture and storage (CCS). We also investigate how, in scenarios from an integrated assessment model that simulates the economics of a climate-constrained world, the prospects for nuclear energy would change if exogenous limitations on the spread of nuclear technology were relaxed. Using the climate change economics model WITCH we find that until 2050 the resulting growth rates of nuclear electricity generation capacity become comparable to historical rates observed...

Read This Paper Even Later: Procrastination with Time-Inconsistent Preferences AgEcon
Fischer, Carolyn.
Salience costs, along with imperfect foresight, have been used in previous studies to explain procrastination of a one-time task. A companion to this paper, "Read This Paper Later: Procrastination with Time-Consistent Preferences" analyzes the extent to which procrastination of a divisible task is compatible with rational behavior. While the fully rational model explains key qualitative observations, it requires an extremely high rate of time preference or elasticity of intertemporal substitution to generate serious procrastination and cannot explain undesired procrastination at all. This paper investigates the extent to which dynamically inconsistent preferences can better explain such impatience and address the issue of self-control failures. Two types...

Read This Paper Later: Procrastination with Time-Consistent Preferences AgEcon
Fischer, Carolyn.
A model of time-consistent procrastination is developed to assess the extent to which the observed behavior is compatible with rational behavior. When a finite work requirement must be completed by a deadline, the remaining time for leisure is an exhaustible resource. With a positive rate of time preference, the optimal allocation of this resource results in more hours spent working (and fewer in leisure) the closer the deadline. Key qualitative findings of psychological studies of academic procrastination are consistent with the standard natural resource management principles implied by the model, when suitably adapted to task aversiveness, uncertainty, and multiple deadlines. However, quantitatively, the fully rational model requires an extremely high...

Strategic Resource Dependence AgEcon
Gerlagh, Reyer; Liski, Matti.
We consider a situation where an exhaustible-resource seller faces demand from a buyer who has a perfect substitute but there is a time-to-build delay for the substitute. We that find in this simple framework the basic implications of the Hotelling model (1931) are reversed: over time the stock declines but supplies increase up to the point where the buyer decides to switch. Under such a threat of demand change, the supply does not reflect the true current resource scarcity but leads to increased future scarcity, felt during the transition to the substitute supplies. The analysis suggests a perspective on costs of oil dependence.

THEORETICAL ANALYSIS OF FOREIGN AID, POLICIES AND STATE INSTITUTIONS AgEcon
Xayavong, Vilaphonh; Gounder, Rukmani; Obben, James.
This paper re-examines the theoretical aid-growth nexus by expounding on the issues relating to policies designed for aid delivery and the lack of aid recipient's state institutional capability to enforce policy conditionality. Two propositions have been demonstrated to explain why policy conditionality attached to aid might not always promote sustainable economic growth in Least Developed Countries. First, the model has simulated that a stable aid flow contributes to economic growth even when aid is fungible. Second, the model has also simulated that unstable aid inflow impairs the favourable effect of stable aid inflow. It is suggested that the contribution of aid to economic growth depends not only on the ability of aid to increase investment in the...
