Rong, Zhao. « Essays on Durable Goods Consumption and Firm Innovation ». FIU Digital Commons, 2008. http://digitalcommons.fiu.edu/etd/215.

Texte intégral
Résumé :
This dissertation comprises three individual chapters. Chapter Two examines how free riding across neighbors influenced the diffusion of color television sets in rural China. Chapter Three tests for asymmetric information between a firm’s management and other investors concerning its patent output. Chapter Four discusses how knowledge stocks influence a patenting firm’s later diversification. Chapter Two documents the existence of a type of network effects - free riding across neighbors - in the consumption of color television sets in rural China, which reduces the propensity of non-owners to purchase. I construct a model of the timing of the purchase of a durable good in the presence of free riding, and test its key implications using household survey data in rural China. Chapter Three tests for asymmetric information between a firm’s management and other investors about its patent output by examining insider trading patterns and stock price changes in R&D intensive firms. It demonstrates that management has considerable information about its patent output beyond what is known to investors. It also shows that the predictive power of insider trading patterns on patent output comes from purchases rather than sales. Chapter Four discusses two sequential channels through which knowledge stocks may influence a firm’s later diversification. One is that firms with more knowledge are more likely to enter a new industry. The other is that firms’ businesses have a better chance of surviving, conditional on being formed. By examining U.S. public patenting firms in manufacturing sectors for 1984-1996, I find that knowledge stocks predict the likelihood of new industry entry when controlling for firm size. However, this predictive power is weakened when diversification effects are included. On the other hand, a survival study of newly established segments shows that initial knowledge stocks have significant positive effects on segment survival, whereas diversification effects are insignificant.

Résumé :
The author of this thesis examines the stochastic behavior of durables consumption in the rational expectations/permanent income hypothesis framework. The testing in this paper parallels the studies conducted by other researchers, who basing their work mainly on quarterly data rejected the frictionless rational expectations/permanent income hypothesis. The distinctive feature of this thesis is that the models are examined using monthly instead of quarterly data. The results of the estimation are compared to the results based on quarterly data. The results show that estimates obtained using monthly data seem to be more consistent with the frictionless rational expectations/permanent income hypothesis than the estimates from quarterly data. Then, by using two subsets of the monthly data representing the first and the last twelve years of a 37 year period, the models are reexamined to explore the possibility of change in the stochastic behavior of personal expenditures on durable goods over time. This results suggest a change in influence of liquidity constraints on the time series behavior of durable goods consumption over the last four decades.

Résumé :
The new classical school's dominance of mainstream economic thought in recent years has brought with it the associated adoption of rational economic agents ( in the Muthian sense) by mainstream economists. This thesis challenges this underlying assumption of human behaviour in the context of the non-durable consumption expenditure decision making process. In doing so, our attention will be placed upon the weak or more general form of the hypothesis, which has come to be known as optimisation. We employ a behavioural methodology in an attempt to ascertain if individuals adhere to the optimising or satisficing model of human behaviour. In doing so time will be spent examining the bounded rationality hypothesis. We also employ a behavioural methodology in producing a non-durable consumption function that is econometrically comparable with an optimising model of non-durable consumption expenditure (namely the permanent income rational expectations hypothesis). The micro results produced in this thesis suggest that the respondents surveyed from non-durable consumption expenditure decisions that are sub-optimal in nature. The formation of these sub-tropical expenditure decisions appear to be a consequence of the cognitive constraints faced by our respondents, which in turn provides empirical support for the bounded rationality hypothesis. On a macro level, our behavioural consumption function generates results that are comparable with those produced by the optimising model employed in this thesis. Our results also question the rational expectations permanent income hypothesis (as it is usually applied), despite making adjustments to the model which remove the underlying assumption of known, constant real interest use

Texte intégral
Résumé :
L’objet de la présente recherche est d’examiner l’impact des attributs durables, tant environnementaux que sociaux, sur la qualité perçue des produits de luxe. Pour atteindre cet objectif, nous avons adopté une approche qui articule deux démarches complémentaires, l’une qualitative auprès des professionnels et consommateurs Parisiens, l’autre quantitative, nous avons mobilisé un modèle expérimental factoriel between-subject, réalisée en France et l’Arabie Saoudite. Le principal résultat de notre étude quantitative est que mentionner l'information durable sur un produit de luxe a un impact négatif sur la qualité perçue. En effet, les consommateurs saoudiens perçoivent un produit de luxe comme étant de qualité inférieure lorsqu’il comporte une information durable. A l’inverse les consommateurs français se montrent indifférents. Plus précisément, nos résultats montrent que c’est plutôt l’information sociale qui présente un effet significatif sur la qualité perçue. L’information environnementale semble avoir un effet neutre. Enfin, nos résultats indiquent que l’effet de l’information sociale sur la qualité perçue est modéré par le goût des consommateurs pour le luxe, l'image RSE et le pays d'origine des consommateurs
The purpose of this research is to examine the effect of sustainable attributes on the perceived quality of luxury products. To get to our goal, a complementary approach using both qualitative and quantitative studies has been adopted. In the qualitative method, two studies with professionals and consumers are conducted. For the quantitative method, we employed an experimental between-subject factorial design realized in France and Saudi Arabia. The key finding of our quantitative study is that mentioning sustainable information has a negative impact on the perceived quality of luxury products. However, while no significant effect is observed in the case of French respondents, Saudi consumers perceive a product to be of lower quality when sustainable information is presented compared to the absence of this information. More particularly, social information impacts strongly and negatively the perceived quality in contrary with environmental information which has no effect. This effect is moderated by the degree of liking of luxury, the CSR image, and consumers’ country of origin

Résumé :
AbstractPollution from post-consumer plastics is a growing global environmental challenge whose negative impacts are exacerbating climate change. Plastics are stable, durable, and hydrophobic. They possess high molecular weight, complex three-dimensional structure, and are not readily available to be used as substrate by biological agents such as microorganisms and enzymes. Polyethylene terephthalate (PET) is one of the examples of petrochemical-based plastics. PET is a strong, clear, and light-weight plastic with global usage in the production of bottles. Technological innovation, policy formulation, advocacy and sensitization, change in consumption pattern, and bioremediation are some of the approaches that are currently being used to mitigate environmental pollution from post-consumer PET bottles. The ubiquitous property of microorganisms and their ability to survive in almost every environment, including very extreme ones, make them good candidate for biodegradation. Bioremediation is simply defined as engineered or enhanced biodegradation. This review discusses the potential of bioremediation as sustainable and environment-friendly tool to clean up post-consumer PET bottles that already accumulate on land, in soil, and in water bodies.

Further conservation of energy continues to be a major priority, even with the advances that have been made in reducing our present consumption. For while energy use has gone down, costs continue to grow. Homeowners continue to look for ways to keep their fuel costs down. Buyers of new homes expect new construction to feature the latest in energy-efficient products such as insulated windows. Many insulated glass units (IGU's) have a thin film coating on one or two of the inner surfaces (#2 and #3) of the unit. Figure 1 illustrates such a unit.

Résumé :
In order to increase the efficiency of advanced microturbines, durable alloy foils are needed for their recuperators to operate at 650°–700°C. Prior work has demonstrated that water vapor in the exhaust gas causes more rapid consumption of Cr from austenitic alloys leading to a reduction in lifetime for the thin-walled components in this application. New commercial alloy foils are being tested in both laboratory tests in humid air and in the exhaust gas of a modified 60kW microturbine. Initial results are presented for a commercial batch of 80μm alloy 120 foil. The Cr consumption rates in laboratory testing were similar to those observed in previous testing. The initial results from the microturbine indicate a faster Cr consumption rate compared to the laboratory test but longer term results are needed to quantify the difference. These results will help to verify a Cr consumption model for predicting lifetimes in this environment based on classical gas transport theory.

Résumé :
Durable alloy foils are needed for gas turbine recuperators operating at 650°–700°C. It has been established that water vapor in the exhaust gas causes more rapid consumption of Cr in austenitic stainless steels leading to a reduction in operating lifetime of these thin-walled components. Laboratory testing at 650°–800°C of commercial and model alloys is being used to develop a better understanding of the long-term rate of Cr consumption in these environments. Results are presented for commercial alloys 709, 120 and 625. After 10,000h exposures at 650° and 700°C in humid air, grain boundary Cr depletion was observed near the surface of all these materials. In the Fe-base alloys, 709 and 120, this depletion led to localized Fe-rich nodule formation. This information then can be used to develop low-cost alternatives to currently available candidate materials.

Résumé :
Advancements in high speed, light craft (HSLC) sea transportation require a main propulsion system that provides relatively high specific power with a minimum of weight/space. For commercial operations, the economics of the propulsion system are considered a key criterion in power plant selection. Marinizing a durable second generation industrial gas turbine, like the Solar Taurus® marine gas turbine, is ideally suited to satisfy the combination of the high vessel speed objective and the operating cost economic justification of commercial HSLC. Since the Taurus gas turbine has evolved from an earlier marine propulsion gas turbine and is in offshore platform service using materials and coatings resistant to marine environments, certification for marine prime propulsion concentrated primarily on operating inclination dynamic loading and the interfaces with the auxiliary support systems. With its high power to weight ratio, reliable performance, competitive first cost, and low operating costs, the Taurus marine industrial gas turbine can be further enhanced by recuperation and variable nozzle designs improving specific fuel consumption and part load efficiencies beyond other alternatives.

Résumé :
Composite admixtures which include active pozzolanic components and high-range water reducers, allows to obtain high-strength, particularly dense and durable concrete to achieve a reduction in resources and energy consumption of manufacturing.Zeolite, containing a significant amount of active silica, can serve as one of the alternative substances to resources and energy consuming mineral admixtures like metakaolin and silica fume. The deposits of zeolites are developed in Transcarpathia (Ukraine), USA, Japan, New Zealand, Iceland and other countries. It is known that zeolite tuffs exhibit pozzolanic properties and are capable to substitution reactions with calcium hydroxide.However, the high dispersion of zeolite rocks leads to a significant increase in the water consumption of concrete. Simultaneous introduction of zeolite tuffs with superplasticizers, which significantly reduce the water content, creates the preconditions for their effective use in high-strength concrete.Along with dehydrated (calcined) zeolite, natural (non-calcined) zeolite expresses itself as an effective mineral admixture of concrete. When using non-calcined zeolite, the effect of increasing in compressive strength at the age of 3 and 7 days is close to the effect obtained when using dehydrated zeolite: 8-10% and 10- 12%, respectively, and 28 days the strength growth is 13-22%. The use of non-calcined zeolite has a significant economic feasibility, so it certainly deserves attention. There were compared the effect of zeolite to metakaolinThe results of the research indicate that the use of composite admixtures, consisted of calcined (non-calcined) zeolite tuff of high dispersity and superplasticizer of naphthalene formaldehyde type, allows to obtain concretes classes C50…C65.

Résumé :
Misfiring is a serious issue for large spark-ignited industrial natural gas engines because it increases fuel consumption and emissions and can ultimately lead to engine damage. Continuous misfiring of an engine cylinder can often be diagnosed based upon vibration measurements or conventional exhaust temperature measurements. The aim of the research described in this paper was to develop a means of detecting not only frequent misfiring of a cylinder, but also isolated, individual misfires. This would make it possible to detect problems early in the progression from sporadic misfire events to the onset of continuous misfiring. The approach used in the study is based upon the sensing of cycle-by-cycle fluctuations in the exhaust temperature from each cylinder. Proprietary circuitry and signal processing techniques are used to extract high frequency temperature information from durable sheathed thermocouples similar to those commonly used for these types of engines. These signal fluctuations can be used to detect momentary drops in exhaust temperature that occur as unburned mixture from a misfire exits the cylinder. The system was developed and validated through engine dynamometer tests using an automotive engine equipped with laboratory-grade cylinder pressure sensors for reference measurements. Further testing was conducted using a medium speed stationary natural gas engine. In both cases, the system was shown to be able to detect and count individual and consecutive misfire events.

Résumé :
A jointed plain concrete pavement represents a reliable, historically proven technical solution for highly loaded roads, highways, airports and other industrial surfaces. Excellent resistance to permanent deformations (rutting) and also durability and maintenance costs play key roles in assessing the economic benefits, rehabilitation plans, traffic closures, consumption and recycling of materials. In the history of concrete pavement construction, slow-to-normal hardening Portland cement was used in Czechoslovakia during the 1970s-1980s. The pavements are being replaced after 40-50 years of service, mostly due to vertical slab displacements due to missing dowel bars. However, pavements built after 1996 used rapid hardening cements, resulting in long-term surface cracking and decreased durability. In order to build durable concrete pavements, slower hardening slag-blended binders were designed and tested in the restrained ring shrinkage test and in isothermal calorimetry. Corresponding concretes were tested mainly for the compressive/tensile strength evolution and deicing salt-frost scaling to meet current specifications. The pilot project was executed on a 14 km highway, where a unique temperature-strain monitoring system was installed to provide long-term data from the concrete pavement. A thermo-mechanical coupled model served for data validation, showing a beneficial role of slower hydration kinetics. Continuous monitoring interim results at 24 months have revealed small curling induced by drying and the overall small differential shrinkage of the slab.

Résumé :
Large natural gas engines are durable and cost-effective generators of power for distributed energy applications. Fuel efficiency is an important aspect of distributed generation since operating costs associated with fuel consumption are the major component of energy cost on a life-cycle basis; furthermore, higher fuel efficiency results in lower CO2 emissions. Leaner operation of natural gas engines can result in improved fuel efficiency; however, engine operation becomes challenging at leaner air-to-fuel ratios due to several factors. One factor in combustion control is ignition. At lean air-fuel mixtures, reliable and repeatable ignition is necessary to maintain consistent power production from the engine, and spark plug quality and durability play an important role in reliability of ignition. Here research of a novel spark plug design for lean natural gas engines is presented. The spark plug is an annular gap spark plug with a permanent magnet that produces a magnetic field that forces the spark to rotate during spark discharge. The rotating arc spark plug (RASP) has the potential to improve ignition system reliability and durability. In the study presented here, the RASP plug was operated in a small natural gas engine, and combustion stability (measured by the coefficient of variation of indicated mean effective pressure (IMEP)) was measured as a function of air-to-fuel ratio to characterize the ignition performance at lean mixtures. Comparisons were made to a standard J-plug spark plug.

Résumé :
Certain waste streams of the US DOE contain radioactive refractory oxides and other components like aluminum zirconium and chromium, which present difficulties during their processing and immobilization. The vitrification of such waste in joule-heated melters at high waste loading is possible only at a temperature exceeding 1150°C. The Khlopin Radium Institute (St.-Petersburg, Russia) jointly with the US Department of Energy has performed a feasibility study on the suitability of the Cold-Crucible Induction Heated Melter (CCIM) technology for the single-stage solidification of a surrogate sludge (C-106/AY-102 HLW Simulant), similar in composition to the High Level Waste (HLW) found at DOE’s Hanford Site (Richland, USA). During the experiments, slurry of simulated sludge and glass formers was metered directly to the CCIM, melted, and the glass product was poured from the melter. The melts were conducted at a mean melt temperature of 1350°C. The experiments produced borosilicate glass wasteforms with a waste oxide loading of 70 weight percent. According to the X-Ray diffraction analysis, the final product had a glass-crystalline structure. The crystalline phase was represented by spinel, (Fe,Mn)Fe2O4, uniformly distributed over the wasteform. The chemical durability of the samples was tested by the Product Consistency Test (PCT), and was considered durable according to the DOE specifications for HLW. In the course of the experiments, data were accumulated on the specific electric power consumption and the throughput of the facility.

Résumé :
Abstract Passive thermal radiative cooling (PTRC) has drawn massive attention in the past few years due to its advantages, including excellent cooling potential, no emission of greenhouse gases, silent operation, low maintenance, and off-grid operation. PTRC has been successfully demonstrated to reduce the electricity consumption required for cooling and ventilation of buildings. Several radiative emitters have been studied in the literature, such as pigmented paints, nanoparticle-based coatings, photonic crystals, metamaterials, and polymers. Among them, polymers have proven to be inherently strong infrared (IR) emitters, scalable, low-cost, flexible, easy to apply, and durable candidates. In addition to these features, biopolymers are eco-friendly and currently abundant in the market. Despite their significant advantages, there have been limited studies on the applications of biopolymers for radiative cooling. In this study, we report promising performances from a commercially available, affordable, and applicable biopolymer, cellulose, as a PTRC emitter. We fabricated several cellulose films with various structural characteristics and thicknesses. The emissivity and reflectivity of these emitter surfaces were measured for the desired wavelengths and direction. The obtained measurements reveal relatively high magnitudes of diffuse emissivity in the atmospheric window and high reflectivity in the solar spectrum range. Using the materials’ reflectivity and emissivity data, we theoretically calculated the net cooling power and the expected temperature drop. Each emitter demonstrated high cooling power and considerable temperature reduction based on the average recorded weather conditions in Lincoln, NE.
