Heterogeneous Responses to Water Conservation Programs: The Case of Residential Users in Los Angeles AgEcon
Hanemann, W. Michael; Nauges, Celine.
We propose a detailed analysis of heterogeneity in households’ responses to water conservation programs (price increase, voluntary and mandatory conservation) during periods of water shortage. Using a unique dataset covering water consumption of all residential users in Los Angeles (California) during the drought (1988-1992), we show that households generally were responsive to the conservation measures but that the magnitude of households’ responses varies depending on the instrument and on households’ characteristics, in particular the size of their lot. Price elasticity is estimated between –0.29 and –0.47 in the high season (June-October), and between 0 and –0.19 in the low season (November-May). Results suggest that the voluntary conservation program...

Contributions towards climate change vulnerability and resilience from institutional economics AgEcon
Diaz Simal, P.; Torres Ortega, S..
This paper analyzes the various contributions made in the economic literature that influence climate change vulnerability. We try to create conceptual order and transparence in the contributions identifying the assumptions and constraints that each school has introduced into academic debate and practical application. We analyze the conceptual framework that articulates the debate, review the theoretical approaches developed in the literature identifying the object of analysis and the basics of each theory, so that the real model implications are established in each case study. From this scheme we derive a clarifying proposal for organizing theoretical discourse. We specifically focus on the theoretical assumptions underlying each model. We conclude with...

The Present Value Model, Farmland Prices and Structural Breaks AgEcon
Gutierrez, Luciano; Erickson, Kenneth W.; Westerlund, Joakim.
We review the constant discount rate present value model of farmland prices using non-stationary panel data analysis. We use panel unit root and cointegration analysis to test if the present value model holds for a sample of 31 U.S. States covering the period 1960-2000. Preliminary results indicate that farmland prices and cash rents are non-stationary and non-cointegrated assuming a constant discount rate. The absence of cointegration may be due to the presence of a regime shift representing a time-varying discount rate. To accommodate this possibility, we introduce new panel cointegration tests that allow for unknown regime shifts in the cointegration relationship. The results suggest that the cointegration hypothesis cannot be rejected if there is a...

Industrial Coal Demand in China: A Provincial Analysis AgEcon
Cattaneo, Cristina; Manera, Matteo; Scarpa, Elisa.
In recent years, concerns regarding the environmental implications of the rising coal demand have induced considerable efforts to generate long-term forecasts of China’s energy requirements. Nevertheless, none of the previous empirical studies on energy demand for China has tackled the issue of modelling coal demand in China at provincial level. The aim of this paper is to fill this gap. In particular, we model and forecast the Chinese demand for coal using time series data disaggregated by provinces. Moreover, not only does our analysis account for heterogeneity among provinces, but also, given the nature of the data, it captures the presence of spatial autocorrelation among provinces using a spatial econometric model. A fixed effects spatial lag model...

Waste Generation, Incineration and Landfill Diversion. De-coupling Trends, Socio-Economic Drivers and Policy Effectiveness in the EU AgEcon
Mazzanti, Massimiliano; Zoboli, Roberto.
Waste generation and waste disposal are issues that are becoming increasingly prominent in the environmental arena both from a policy perspective and in the context of delinking analysis. Waste generation is still increasing proportionally with income, and economic and environmental costs associated to landfilling are also increasing. This paper provides a comprehensive analysis of waste generation, incineration, recycling and landfill dynamics based on panel data for the EU25, to assess the effects of different drivers (economic, structural, policy) and the eventual differences between western and eastern EU countries. We show that for waste generation there is still no Waste Kuznets Curve (WKC) trend, although elasticity to income drivers appear lower...

Determinants of Foreign Direct Investment of OECD Countries 1991-2001 AgEcon
Gast, Michael W..
Using a fixed-effects panel data approach, FDI flows of 22 OECD countries are explained by gravity equations over the period 1991-2001. It is distinguished between all available observations, Intra-EU25 observations only, and observations not belonging to the EU25 area in order to control for EU-specific effects. Regressions are repeated with exports as dependent variable in order to capture diverging influences for trade flows. Changes in total market size and relative market size are important factors that lead both FDI and exports in the same direction. However, relative market size is only significant in the FDI equation when variation between the EU25 area and other investment is taken into account, thus indicating a concentration of FDI within...

Inside the 'Black Box' of Project Star: Estimation of Peer Effects Using Experimental Data AgEcon
Boozer, Michael A.; Cacciola, Stephen E..
The credible identification of endogenous peer group effects— i.e. social multiplier or feedback effects —has long eluded social scientists. We argue that such effects are most credibly identified by a randomly assigned social program which operates at differing intensities within and between peer groups. The data we use are from Project STAR, a class size reduction experiment conducted in Tennessee elementary schools. In these data, classes were comprised of varying fractions of students who had previously been exposed to the Small class treatment, creating class groupings of varying experimentally induced quality. We use this variation in class group quality to estimate the spillover effect. We find that when allowance is made for this ‘feedback’ effect...

Parametric and Non-Parametric Estimation of Soil Conservation Impact on Productivity in the Northwestern Ethiopian Highlands AgEcon
Kassie, Menale; Holden, Stein T..
The impact of fanya juu bunds on productivity in a high rainfall area in the Ethiopian highlands is analyzed based on data from a cross section household survey with multiple plot observations per household. The results from parametric and non-parametric analysis indicated that productivity from conserved plots was lower than from non-conserved plots. The Oaxaca-Blinder productivity decomposition results showed that there was little difference in plot characteristics between conserved and non-conserved plots, however the returns to those characteristics were higher for non-conserved plots. The sensitivity analysis, increasing fodder grass production on bunds, suggests that there are possibilities to make conserved plots as productive as non-conserved ones....

Exchange Rates Impacts on Agricultural Inputs Prices using VAR AgEcon
Yeboah, Osei-Agyeman; Shaik, Saleem; Allen, Albert J..
The effects of the U.S. dollar exchange rate versus the Mexican peso are evaluated for four traded nonfarm-produced inputs (fertilizer, chemicals, farm machinery, and feed) in the U.S. Unit root tests suggest that the exchange rate and the four input price ratios support the presence of unit roots with a trend model but the presence unit roots can be rejected in the first difference model. This result is consistent with a fixed price/flex price conceptual framework, with industrial prices more likely to be unresponsive to the exchange rate than farm commodity prices.

Estimation and Inference for Threshold Effects in Panel Data Stochastic Frontier Models AgEcon
Yelou, Clement; Larue, Bruno; Tran, Kien C..
One of the most enduring problems in cross-section or panel data models is heterogeneity among individual observations. Different approaches have been proposed to deal with this issue, but threshold regression models offer intuitively appealing econometric methods to account for heterogeneity. We propose three different estimators that can accommodate multiple thresholds. The first two, allowing respectively for fixed and random effects, assume that the firms’ specific inefficiency scores are time-invariant while the third one allows for time-varying inefficiency scores. We rely on a likelihood ratio test with m − 1 regimes under the null against m regimes. Testing for threshold effects is problematic because of the presence of a nuisance parameter which...

Financial Risks, Bankruptcy Probabilities, and the Investment Behaviour of Enterprises AgEcon
Kirchesch, Kai.
The link between investment and finance usually enters the empirical literature in the form of financial constraints which are defined as the wedge between the costs of internal and external finance or as the risk of being rationed on the credit market. In this context, the sensitivity of investment with respect to single internal or external finance indicators is assumed to be appropriate to proxy for these constraints. However, enterprises that rely on external funds do not only face this external finance premium and potential borrowing limits, but also the risk of not being able to meet their repayment obligations and thus the risk of bankruptcy. If the risk of bankruptcy enters the profit maximization of the firm, the resulting empirical investment...

Institutions, Policy Reforms and Efficiency in New Member States from Central and Eastern Europe AgEcon
Bojnec, Stefan; Ferto, Imre; Jambor, Attila; Toth, Jozsef.
This paper investigates determinants of agricultural sector efficiency in ten new member states (NMS-10) of the European Union (EU) from Central and Eastern European countries by the non-parametric method Data Envelopment Analysis (DEA) and the panel data analysis. The agricultural sector efficiency varies between the NMS-10. We have found positive and significant association of the agricultural sector efficiency with the natural agricultural factor endowments, average farm size, farm specialization, small-scale farms, and the EU integration process. The foreign direct investments have an ambiguous affect, while the nominal assistance rate is not found significant. Reform and institutional developments and liberalization are associated with the...

A metafrontier approach to measuring technical efficiencies across the UK dairy sector AgEcon
Barnes, Andrew Peter; Revoredo-Giha, Cesar; Sauer, Johannes.
A regional approach is applied to measure technical efficiencies on dairy farms which employs the deterministic metafrontier approach. We construct six super regions for the UK, i.e. Eastern, Western, Northern England, Wales, Scotland and Northern Ireland. Data are collected through three different administrative systems, all be it under the same FADN guidance. We find for dairy farming comparative indicators of performance in all three data sets. The stochastic frontier approach is applied to construct 6 regional frontiers and a pooled (UK) dataset for comparison. A likelihood ratio test rejects the null hypothesis that these regions operate under a common frontier which may indicate bias in previous attempts to measure dairying efficiency at the country...

The evolution of land values in Italy. Does the influence of agricultural prices really matter? AgEcon
Mela, Giulio; Longhitano, Davide; Povellato, Andrea.
Interest towards farmland market has been increasing in recent years. In developing countries there is rising concern about land being purchased by foreign investors, while in the developed world the debate is centred on whether agricultural factors are still the main determinants of land values or not. This work assesses the determinants of land values in Italy using panel data techniques during the time span 1992-2010. In Italy farmland values have historically been influenced more by natural characteristics of the land than agricultural prices. However, lately non-agricultural factors have been increasing their importance. We find that agricultural prices only slightly affect average land values in Italy. Main determinants of land prices are the yield...

Paths to Success: The Relationship Between Human Development and Economic Growth AgEcon
Boozer, Michael A.; Ranis, Gustav; Stewart, Frances; Suri, Tavneet.
This paper explores the two-way relationships between Economic Growth (EG) and Human Development (HD), building on an earlier work by Ranis, Stewart, and Ramirez (2000). Here, we show that HD is not only a product of EG but also an important input to it. The paper develops new empirical strategies to estimate the strength of the two-way chains connecting HD and EG. Building on existing growth literature, we explore the empirical determinants of positive growth trajectories running from HD to EG and find that HD plays an essential role in explaining growth trajectories. Our findings point to the empirical relevance of endogenous growth models in general, and threshold effect models in particular. We also develop a measure of the strength of the EG to HD...

The Effect of Retail Grocery Coupons for Breakfast Cereals on Household Purchasing Behavior AgEcon
Berning, Joshua P.; Zheng, Hualu.
We examine the affect of retail and manufacturer coupons on the nutritional quality of breakfast cereal purchases made by households. Using household level purchase data we find that coupon usage has a significant impact on the nutritional quality of cereals purchased by households. Specifically, we find that the average sugar content decreases and the fiber content increases. This suggests that coupons have a positive impact on the nutritional quality of cereals purchased by households, holding all other factors constant. Given the prolific use of coupons by households and the fact that they offer both a price discount and an advertisement for products, they might be an effective way to help guide consumers to healthier food choices.

Democratic Institutions and Environmental Quality: Effects and Transmission Channels AgEcon
Romuald, Kinda Somlanare.
This paper aims at analysing the effect of democratic institutions on environmental quality (carbon dioxide per capita, sulfure dioxide per capita) and at identifying potential channel transmissions. We use panel data from 1960 to 2008 in 122 developing and developed countries and modern econometric methods. The results are as follows: Firstly, we show that democratic institutions have opposite effects on environment quality: a positive direct effect on environment quality and a negative indirect effect through investments and income inequality. Indeed, democratic institutions attract investments that hurt environment quality. Moreover, as democratic institutions reduce income inequality, they also damage environment. Secondly, we find that the direct...

The Effects of Class Size on the Long Run Growth in Reading Abilities and Early Adult Outcomes in the Christchurch Health and Development Study AgEcon
Boozer, Michael A.; Maloney, Tim.
This paper utilizes the feature of the CHDS data from New Zealand that children are sampled for extremely long individual histories of their class size experiences as well as their scholastic and early labor market outcomes. Our interest is to explore the full set of empirical implications of the recent experimental evidence on class size effects on student achievement from the United States in Project STAR for observational data. We argue that one implication of Project STAR is that only persistent class size reduction policies may have detectable effects, and so the longitudinal aspect of CHDS is necessary to detect class size effects. We account for the observational nature of the CHDS (in that children were not randomly assigned to different class...

The Persistence of Poverty in Rural China: Applying an Ordered Probit and a Hazard Approach AgEcon
Glauben, Thomas; Herzfeld, Thomas; Wang, Xiaobing.
The present study investigates the analysis of poverty persistence of Chinese farm households in the well-off Zhejiang province in the southeast. We firstly apply an ordered probit model examining household, farm, and regional characteristics affecting the probability that households are chronically poor. In addition, we apply a hazard approach to identify the risk of falling into and climbing out of poverty. Results indicate that there are increasing chances to climb out of poverty over time, and that the risk of falling into poverty seems to decrease after the household spent some time outside poverty.
