Ethanol and sugarcane expansion in the Brazilian Cerrado: farm, industry, and market analyses

Sant'Anna, Ana Cláudia January 1900 (has links)
Doctor of Philosophy / Department of Agricultural Economics / Jason S. Bergtold / Tian Xia / Brazil is one of the leading producers of ethanol, sugar, and sugarcane. Increasing demand for biofuels aligned with public policies prompted the expansion of sugarcane into the Brazilian Cerrado, particularly, into the states of Goiás and Mato Grosso do Sul. The overall purpose of this dissertation, comprised of three essays, is to understand the impacts from the sugarcane expansion on farmers, processors, and the market. At the market level, the first essay, estimates the impacts of public policies and market factors on ethanol and sugar, supply and demand, in Goiás and Mato Grosso do Sul, using three-stage least squares. Results show that ethanol supply is sensitive to public policies whereas the sugar supply is sensitive to market prices. Sugar and ethanol were found to be complementary outputs. For ethanol expansion to be sustainable the ethanol market must be developed to the extent that it relies on market factors and is no longer dependent on public policies. At the farmer level, the second essay, examines farmers' willingness to sign a sugarcane contract with a mill in the Brazilian Cerrado. A hypothetical stated choice experiment was conducted with farmers in Goiás and Mato Grosso do Sul. Respondents choose between three contracts (land rental, agricultural partnership and supply) and two optout options ("keep current contract" or "not grow sugarcane"). A single and a two opt-out random parameters models were estimated. The two opt-out model allowed for a better interpretation of the status quo. Willingness to pay, direct and cross-elasticity measures for contract attributes were calculated. Results showed that farmers prefer contracts with higher returns, shorter duration and a lower probability of late payments. Farmers seemed to prefer to renting out their land to the mill than to produce sugarcane themselves, which could lead to consequences for rural development and the sustainability of sugarcane expansion. At the processor level, the third essay investigates the impact of vertical coordination on input-oriented technical efficiency using data envelopment analysis (first stage) and a Tobit censored model (second stage). 204 Brazilian mills were considered. The second stage controlled for vertical integration as well as other characteristics of the mill. Vertical integration was measured as the percentage of total sugarcane used, supplied by mills. A negative, though minimal, relationship between vertical integration and technical efficiency was found. Hence, technical efficiency is not the major driver of vertical integration. Other vertical coordination strategies may bring more benefits in terms of technical efficiency (e.g. contracts). Drivers of vertical integration seem to vary according to the characteristics of the location of the mill.

Income, Energy Taxation, and the Environment : An Econometric analysis

Ghalwash, Tarek January 2006 (has links)
<p>This thesis consists of four papers: two of them deal with the relationship between consumption, energy taxation, and emissions on macro level, and two of them focuses on the effects of changes in consumption and income on the environmental quality on a micro level.</p><p>The main objective of paper [I] is to examine how exogenous technological progress, in terms of an increase in energy efficiency, affects consumption choice by Swedish households and thereby emissions of carbon dioxide (CO2), sulphur dioxide (SO2) and nitrogen oxide (NOx). The aim of the paper is closely related to the discussion of what is known as the “rebound effect”. To neutralise the rebound effect, we estimate the necessary change in CO2 tax, i.e. the CO2 tax that keeps CO2 emissions at their initial level. In addition, we estimate how this will affect emissions of sulphur dioxide and nitrogen oxides. The results indicate that an increase in energy efficiency of 20 percent will increase emissions of CO2 by approximately 5 percent. To reduce the CO2 emissions to their initial level, CO2 tax must be raised by 130 percent. This tax increase will reduce the emissions of sulphur dioxide to below their initial level, but will leave the emissions of nitrogen oxides at a higher level than initially.</p><p>One of the premises implied in paper [II] is that the changes in consumer prices, as a result of changes in environmental taxes, may send a different signal to the consumer compared with other changes in consumer prices, such as changes in producer price. In addition, this assumed difference in the signaling effect of the changes in environmental taxes, compared to changes in the producer price, may also differ between different commodities. To achieve the objectives a system of demand functions for Swedish households is estimated. To test for the signalling effect of environmental taxes the consumer price for energy goods is partitioned into a producer price part and a tax part.</p><p>In Paper [III], we estimate the income elasticity of demand for recreational services and other traditional groups of goods in Sweden and we test for potential changes in such estimates over the twentieth century. The paper uses Swedish household surveys for the years 1913, 1984, 1988, and 1996. Because of the difficulty of directly observing the demand for recreational services, we employ an indirect methodology by using the demand for some outdoor goods as proxies for the recreational services demand.</p><p>In paper [IV], we investigate the relationship between pollution and income at the household level. Here we want to investigate, and hence contribute to the existing literature, under what conditions concerning individual preferences and the link between consumption and pollution a linear relationship are to be expected, but also to empirically assess the relationship. To achieve our objective we formulate a model determining different type of households’ choice of consumption for goods. Furthermore we link the demand model to emission functions for the various goods. The results from the empirical analysis show that, at least in a close neighbourhood of observed income/pollution, we can reject linearity for all three types of pollutions, CO2, SO2, and NOx. According to our results the pollution/income relationships are all strictly concave. Thus the implication is that the income distribution seems to matter in the sense that equalization of income will lead to higher emissions. Furthermore it is shown that the slope as well as the curvature differs between different types of households, which means that preferences differ across households.</p>

Three Papers on the Effects of Competition in Engery Markets

Choi, Wai Hong January 2013 (has links)
This thesis comprises three papers examining the impact of competitive pricing or competition on participants in energy markets. The scope of each paper is narrow but focused, dealing with one particular aspect of competition in each market under study. It is hoped that results from these three studies could provide valuable policy lessons to public policy makers in their task to create or maintain competition in different energy markets, so as to improve efficiencies in these markets. The first and second papers examine the load shifting behavior of industrial customers in Ontario under real time pricing (RTP). Using Hourly Ontario Energy Price (HOEP) data from 2005 to 2008 and industry-level consumption data from all industrial customers directly connected to the transmission grid, the first paper adopts a Generalized Leontief specification to obtain elasticities of substitution estimates for various industry groups, while the second paper adopts a specification derived from standard consumer theory to obtain price elasticity estimates. The findings of both papers confirm that in some industries, industrial customers who are direct participants of the wholesale market tend to shift consumption from peak to off-peak periods in order to take advantage of lower off-peak prices. Furthermore, in the first paper, a demand model is estimated and there is evidence that the marginal effect of hourly load on hourly price during peak periods is larger than the marginal effect during off-peak periods. An important policy implication from the results of these papers is that while RTP is currently limited to industrial customers, it does have positive spillover effects on all consumers. The third paper uses a unique panel dataset of all retail gasoline stations across five Canadian cities from late-2006 to mid-2007 to examine the effect of local competition on market shares and sales of individual stations. The base empirical specification includes explanatory variables representing the number of same brand stations and the number of different brand stations within a 3km radius to identify brand affiliation effect. It is found that the number of local competitors is negatively correlated with market share and sales. More interestingly, a same brand competitor has a larger marginal impact on market share and sales than a competitor of a different brand. These findings suggest that additional local competition leads to cannibalization of market share among existing stations, rather than create new demand. Another implication is that relying only on the number of different brands operating within a geographic market could understate the competition intensity in the local market.

Estimating the elasticities of labour supply for SMEs in Bosnia and Herzegovina

Šabić, Ada January 2014 (has links)
This Master thesis aims at testing the intertemporal substitution hypothesis (ISH) for small and medium enterprises in Bosnia and Herzegovina. We predicted a positive relationship between the hours worked and the transitory changes in wages, and tested the hypothesis using the data collected via surveys of small entrepreneurs in North-Western Bosnia and Herzegovina; collecting data on daily income and the hours worked. The estimated wage elasticities are positive and different from zero, according to which it appears that the hypothesis of negative wage elasticities has no empirical evidence in the case of Bosnian and Herzegovinian entrepreneurs. This result implies that the intertemporal labour substitution hypothesis found supportive evidence and that we can reject the daily targeting hypothesis. We also argue that entrepreneurs tend to pursue profits across working days because their main motive for running a business is the accumulation of capital and wealth, so that they follow the pattern of intertemporal labour substitution. The findings can be explained by an unfavourable business climate in Bosnia and Herzegovina, which is a result of a long-lasting transition process the country is still undergoing. Keywords: labour supply, elasticity, intertemporal substitution, daily targeting, SMEs,...

Employment Decentralization and Bus Rapid Transit in an Edge City Corridor: Veterans Boulevard in Greater New Orleans

Marcantel, Taylor A 15 December 2012 (has links)
The continued decentralization of employment in U.S. regions has led to the emergence of large employment centers outside of traditional Central Business Districts. Edge Cities in particular, with their high office space densities, significantly influence surrounding land uses and regional commuting patterns. However, existing transit systems tend to be oriented to historic Central Business Districts and the level of service for transit in suburban areas remains considerably below that of central cities. Adequately serving suburban Edge Cities with transit is critical in maintaining and improving access to jobs by transit and mitigating automobile congestion. This study explores the suitability of a Bus Rapid Transit system along the Veterans Boulevard corridor in Greater New Orleans. It does this by analyzing residential and employment densities and existing commuting patterns along the corridor. It also explores the potential impact of BRT improvements on transit ridership in the corridor.

Estimating price and quality elasticities of international trade / Estimer le prix et la qualité de l'élasticité du commerce international

Thanagopal, Thannaletchimy 05 December 2014 (has links)
Estimer le prix et la qualité de l'élasticité du commerce international. / This thesis is a compilation of three essays that estimate the ‘true’ trade price elasticity of demand while adjusting for the effect of quality in the trade models. Quality in this thesis is introduced via our own proxy for quality known as ‘knowledge’. This proxy takes into account not only direct expenditures (and hence stocks) spent on research and development but also indirect expenditures (and stocks) through positive externalities originating from innovation efforts by other countries and other industries. In addition, the main trade database used in this thesis is the WIOD (World Input-Output Database) which provides bilateral trade flows, at the industrial level for 35 industries in manufacturing and services based on the ISIC Rev. 2 (International Standard Industry Classification Revision 2) over a period of 17 years (from 1995 to 2011). The first essay, “Analyzing BRIC Competitiveness in EU-14, Japan, US and Norway” looks at the competitiveness of the emerging nations notably the BRICs (Brazil, Russia, India and China) compared to the EU-14 countries (excluding Luxembourg), Japan, the United States and Norway in 15 distinct manufacturing goods industries over a period of 16 years (1996 to 2011). We use the CMSA (Constant Market Share Analysis) econometrically to dissect the competitive effect of the BRICs in terms of price and quality effects. The CMSA is useful in explaining the gain in export market shares of a country through two terms - the structural effect and the competitive effect. However, the model fails to define the type of competitiveness - whether a country is competitive in terms of prices (price competitiveness) or in terms of non-price factors such as quality and variety (non-price competitiveness). This essay attempts to improve this analysis by estimating individual price and non-price competitive effects using an export market share equation. We find evidence of the competitive effect in BRIC exports towards major industrialized countries namely EU-14 (excluding Luxembourg), Japan, United States and Norway. We also find that the gain in BRIC export market share is largely attributed to better price competition rather than non-price competition. The industrial results, however, indicate the presence of non-price competitiveness in selected homogeneous product industries during this period, suggesting the beginning of a shift in BRIC export competitiveness.
