Background: Studies of complex and big-ticket tenders such as construction contracts have been the main research focus of public procurement. The efficiency of these low frequency transactionsis inherently hard to study, since the real world offers a wide range of variables that could explain the discrepancies. What is not studied to large extents are high frequency transactions, with low transaction volume, of common goods. These purchases are mostly overlooked due to the lack of documentation that exists, primarily explained by the low degree of digitalization and transparency on smaller contracts/transaction that fall below the EU reporting thresholds.Purpose: The purpose of this research is to examine the existence of price discrepancies for homogenous goods in public procurement between Swedish municipalities. Furthermore, provide insight and possible explanations to this phenomenon in accordance with economic theory.Method: This study opted to use a quantitative method of research to look at different municipalities and their procurement invoices. The quantitative data has been compiled and adjusted to comparable numbers, so that differences can be identified with clarity.Conclusions: The study concludes that there are significant price discrepancies for homogenous goods in the public procurement sector. With price variations ranging from being negligible to paying twice the price. The selected theoretical framework points towards opportunism and asymmetric information being the main sources of the price discrepancies. Improvement could possibly be made by shifting policies towards further digitalization of the procurement process and horizontally integrating the public sphere. In turn reducing asymmetric information and transaction costs, making less room for opportunistic behavior due to improvements in ex ante and ex post costs. From the results of the empirics, a speculative cost saving potential of 7.90 % is estimated.

Targeting farms with low costs of reducing agro-pollution has been suggested as a means to reduce control costs. The potential to use better information to reduce costs of achieving a regulatory performance standard was evaluated. Using the Lower Susquehanna watershed as a case study, three strategies to target reductions in nitrogen runoff from dairy farms were studied: 1) no information -- uniform allocation, 2) perfect information -- cost-effective allocation, and 3) partial information - estimated cost-effective allocation. From no information to perfect information, more detailed information about the farms’ marginal compliance costs with a reduced nitrogen runoff standard was collected. Two strategies to target the performance standards, the private and social cost-effective allocation (private cost-effective allocations minimized farm compliance costs while social cost-effective allocations minimized the sum of compliance plus transaction costs) were also compared. Each strategy's total control cost (compliance plus transaction costs) were estimated for a 237 dairy farm sample with a modified micro parameter (bieconomic) model which preserves the watershed heterogeneity. Because cost-effective performance standards involve large transaction costs, they were compared to two design standards which have lower transaction costs. It was found that targeting problem farms in the Lower Susquehanna watershed could save nearly $3 million for the sampled 237 farms. Extrapolating this result to the 6,662 dairy farms in the watershed could save the state more than $55 million over a uniform allocation of responsibility. Results also show that the social cost-effective allocation of control responsibilities (based on marginal compliance plus transaction costs) in targeting policies targets only 50 percent of the dairy farms with a mean control cost per pound of $11 compared to $47 per pound with the uniform performance standard applied to all the farms. This study suggests that a few farms in the Lower Susquehanna should be targeted a large reduction burden. Criteria to target these farms should be: somewhat larger farms with steep and long slopes, on soil hydrological groups C and D, close to surface water, that have no or few best management practices in place, and grow large amounts of corn. Cost-effective practices for dairy farmers in the Lower Susquehanna are manure incorporation and storage, eliminating or reducing winter manure spreading, and using more strip-cropping. The value of perfect information was found to exceed the value of partial information in the study area because the total control costs were lower. Compliance costs for perfect information under the social cost-effective allocation were $853,911 compared to $968,121 under the partial information strategy. Total transaction costs were $126,996 for the perfect information and $74,368 for the partial information strategy. Total control costs were $980,907 for the perfect information and $1,042,489 for the partial information strategy. Results for the private cost-effective allocation were similar. The private cost-effective targeting strategy did not differ significantly from the social cost-effective targeting strategy mainly because aggregate compliance costs make up 99% of the total control costs. The two regulatory design standards requiring manure storage and stripcropping on more erosive soils were also evaluated. However, neither design standard achieves the 40 percent nitrogen delivery reduction goal in the watershed. / Ph. D.

In this dissertation, we study the effects of emerging biomass markets on land use changes between alternatives of agricultural production, conventional timber production, and forest woody biomass production for energy use. Along with the uncertainty associated with woody biomass prices and rents, transaction costs incurred to land use play an important role in land allocation decisions and make this study distinct from other work. In Chapter 1, we introduce the background and objectives of our study. In Chapter 2, we analyze the behavior of a risk-neutral private landowner and social planner under uncertainty of woody biomass prices, assuming that there is a market emergence at some unknown time point in the future. Market emergence is characterized by a price jump and a certain timing of the price jump. Six different price jumps and five different timings of bioenergy market emergence are adopted to study their collective effects on land use change between agriculture and forestry. Chapter 3 studies this problem for a risk-averse private landowner. Two measures of relative risk aversion are used to examine how a landowner's preference may affect his or her land use decision. In Chapter 2, we find that, for three different quality categories of land, land rents from forestry increase significantly for higher price jumps and decreases in the length of time until bioenergy market emergence. One of the most important results is concerned with the presence of transaction costs. Here, we find that these costs may require unrealistic market emergence scenarios to lead to bioenergy adoption on any large scale. This result is even more likely with nonlinear transaction costs. Land allocation decisions in Chapter 3 are distinctly different from those in Chapter 2, due to the introduction of landowner risk aversion. In certain market emergence cases, some land units retain in agriculture entirely when the landowner is risk averse . The Chapter 4 studies a stochastic optimization problem of land use, assuming that woody biomass rents follow a stochastic diffusion called geometric Brownian motion that is later discretized by a binomial option pricing approach. The problems in Chapters 2 and 3 assume that the landowner must make all decisions at the beginning of his or her time horizon. This assumption is relaxed in Chapter 4. Now, the landowner is allowed to revise his or her land allocation decision among three alternatives over time as information about market emergence is collected. We observe that the different forms of transaction costs are not as significant as in Chapters 2 and 3. However, different values of volatility of forest biomass rents give rise to different land allocation decisions, especially for the land of high quality. / Ph. D.

Da oltre vent’anni l’Unione Europea (UE) è protagonista di un acceso dibattito circa l’orami vasta adozione di OGM in agricoltura. Laddove la maggior parte dei paesi Nord e Sud americani ha già largamente introdotto tali colture, l’UE è invece in forte ritardo, complice una legislazione basata sul Principio di Precauzione. Queste discrepanze nei i processi legislativi hanno portato a galla alcune problematiche di carattere commerciale: primo, la riduzione delle disponibilità di materia prima non-OGM costituisce un problema per la stabilità delle filiere ad essa dedicate; secondo, il commercio di prodotti convenzionali è compromesso dalla possibilità di riscontrare varietà OGM non approvate in UE all’interno delle partite provenienti da paesi terzi. In ultimo, data l’ampia diffusione di OGM nelle Americhe, è lecito porsi il quesito di come tale tendenza abbia influito sui prezzi delle materie prime agricole. In questa tesi si cercherà di analizzare queste tematiche. Per prima cosa, ci occupiamo di capire come la filiera della soia non-OGM italiana sia organizzata e gestita in modo da minimizzare i rischi di presenza avventizia. La conclusione è che le forme di governance ibride garantiscono la migliore forma di gestione. Successivamente ci domandiamo se le diversità legislative in materia di OGM abbiamo un impatto sull’import Europeo di mais e soia. Utilizzando l’analisi della domanda, riscontriamo che i paesi esportatori competono o sul prezzo o in base alla disponibilità stagionale di prodotto. In ultimo, utilizzando serie storiche, analizziamo il ruolo del tasso di adozione di soia OGM sui prezzi reali; ciò che osserviamo indica che questo ha un effetto deflattivo di breve periodo, ma di scarso peso. / The debate on the increasing adoption of GMOs in agriculture has been in vogue for the last twenty years. Whereas most North and South American countries have largely adopted GMOs, the European Union (EU) has not. Since the EU legislation is based on the Precautionary Principle, the introduction of new GM varieties has been slow. These discrepancies put forward some fundamental issues: first, the decreasing availability of non-GM raw materials poses the sustainability of these supply chains at risk; second, the trade of conventional products is undermined by the possible occurrence of unauthorized GMOs in overseas. Last, the wide adoption of GM crops in North and Latin America poses the question of what effect the spreading of biotechnology in agriculture has exerted on market prices. In this thesis, we try to answer these three research questions. First of all, we investigate how the Italian supply chain for non-GM soybean meal is framed and managed in order to reduce the risk of adventitious presence. We find that hybrid organizations represent the best governance form. Next, we assess the role of legislative diversities (regarding GMOs) on EU import decisions through import demand analysis. We conclude that competition among exporters is solely based on price and seasonality. Last, we disentangle the role of GMOs adoption on the variability of US soybean prices. Results indicate that a higher rate of adoption reduces real soybean market prices, yet the effect is short lived and not much relevant.

Thesis (MScAgric)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: The agro-food sector is swiftly moving towards an internationally interconnected system with a large variety of complex relationships, due to year-round supply, product differentiation and developments in information technologies, with the aim of enhancing competitiveness. In this context, vertical linking in the agro-food business especially, vertical coordination has gained attention. A case study approach is used to analyse two fruit supply chains -the table grape and citrus fruit chain. The study uses a transaction cost approach to analyse the supply chain of the fruit industry in South Africa. Transaction cost analysis (TCA) represents one possible approach to understanding and evaluating supply chain management and has the potential to be combined in an interdisciplinary setting with the insights provided by the marketing, logistics and organisational behaviour literatures. By means of literature study, constructs are identified that help explain the choices made, with regard to governance structures and the sources of competitiveness of supply chains. The question of governance structures is addressed in transaction cost economics (TCE) where asset specificity is of major importance. The sources of competitiveness are addressed both in the literature study and from discussions undertaken with key industry representatives. The empirical application of the TCE theory helped demonstrate the extent to which the exporter has adapted to changes in the global environment. The study revealed that for both supply chains, the role-players overcompensate to minimise their risk. Hence vertical integration rather than outsourcing takes precedence. Bilateral contracting and strategic alliances should be given priority to enhance effective communication, commitment and collective decision-making. This growing recognition of the competitive advantage that can be gained through improving coordination in the supply chain is the starting point for SCM initiatives and, these are important signals that in the long run will determine the sustainability and competitiveness of the industry. / AFRIKAANSE OPSOMMING: Die landbou-voedsel sektor is vinnig besig om na 'n internasionale interafhanklike stelsel met 'n groat verskeidenheid van ingewikkelde verhoudings te beweeg, as gevolg van heel-jaar aanbod, produk differensiasie en ontwikkeling in tegnologie, met die doel om meer mededingend te wees. In hierdie konteks geniet vertikale skakelinge in die landbou-voedsel bedryf, en veral vertikale koordinasie, baie aandag. 'n Gevalle studie benadering is gevolg om twee vrugte waardekettings te analiseer -die tafeldruiwe en sitrus ketting. Die studie maak gebruik van 'n transaksie koste benadering om die waardeketting van die Suid-Afrikaanse vrugte bedryf te analiseer. Transaksie koste analiese (TKA) verteenwoordig een moontlike benadering om waardekettingbestuur te verstaan en te evalueer. Dit het oak die potensiaal om gekombineer te word in 'n interdissiplinere omgewing met insigte wat deur bemarking, logistiek en organisatoriese gedrags literatuur verskaf word. Konstruksies is met behulp van literatuur studies ge"identifiseer wat help om die keuses wat gemaak is met betrekking tot bestuurstrukture en die bran van mededingendheid van waardekettings. Die kwessie van bestuurstrukture word aangespreek deur transaksie koste ekonomie (TKE) waarin bate-spesifiekheid van groat belang is. Die bran van mededingendheid is aangespreek deur beide literatuur te bestudeer en deur besprekings met sleutel-figure in die bedryf. Die empiriese toepassing van die TKE teorie help om die mate waarin die uitvoerder aangepas het tot veranderinge in die globale omgewing aan te toon. Die studie bewys dat firmas in beide waardekettings oorkompenseer vir transaksie koste deur vertikale integrasie in plaas van kontrakte. Bilaterale kontrakterings en strategiese vennootskappe moet prioriteit geniet om effektiewe kommunikasie, verpligtinge en kollektiewe besluitneming te verbeter. Die groeiende erkenning wat gegee word aan mededingende voordeel wat gewen kan word deur koordinasie in die waardeketting te verbeter is die begin punt vir ketting initiatiewe en, dit is belangrike seine wat die volhoubaarheid en mededingendheid van die bedryf in die lang termyn sal bepaal.

Thesis (MScAgric)--Stellenbosch University, 2005. / ENGLISH ABSTRACT: This study examines the role of contracting in reducing transaction costs in smalIscale mussel farming in Saldanha Bay. Masiza Mussel Growers (Masiza), an initiative by the public and private sector to address the imbalances of the past through entrepreneurial development, are used as a case study hence a case study approach is followed. Two transactions were considered, one between Masiza and Blue Bay Aqua Farm (Blue Bay) and another between La Vie Sea Food Products (La Vie) and Masiza. These transactions form the basis for analysis. Market risks, uncertainties, environmental risks, information incompleteness, illiteracy, limited technical knowledge of farming, lack of appropriate infrastructure and lack of transport facilities are identified and examined as possible sources of transaction costs that constrain the existing supply chain relationship. The study shows that asset specificity, time specificity, and site specificity playa positive role in the supply chain as they result in relative dependency amongst parties. Opportunistic behavior within the existing supply chain is neutral, but appears to be relatively high on the spot or fresh live market. Characteristics of market transactions for mussels and associated transaction costs suggest that fresh-live spot market trading for Masiza is difficult to attain. This therefore motivates parties (Masiza) to contract or vertically integrate, as it is costly and risky to rely on spot live markets. Interviewees (Masiza) pointed out that the benefits associated with contract farming outweigh the transaction costs associated with this governance structure. Hence a market specification contract with the La Vie (a processing company), and a production management and resource provision contract with Blue Bay (a larger producer) were designed. They reduce transaction costs associated with fresh-live markets and ensure a more stable and reliable market for growers. / AFRIKAANSE OPSOMMING: Die studie ondersoek die rol van kontraktering in die vermindering van transaksie koste vir klein skaal mossel produsente in Saldanha baai. Die Masiza Mussel Growers (Masiza) word as gevallestudie gebruik. Twee transaksies met o.a. Blue bay Aqua Farm (Blue Bay) en La Vie Sea Food Products (La Vie) was ter sprake en laasgenoemde het as basis vir die analise gedien. Mark risiko, onsekerheid, omgewings risiko, gebrekkige informasie, ongeletterdheid, beperkte tegniese kennis, beperkte infrastruktuur en beperkte verroer fasiliteite is geidentifiseer en ondersoek as moontlike oorsake van hoë transaksie koste wat die huidige aanbod ketting strem. Die studie toon aan dat interafhanklikheid tussen die betrokke partye deur bate, tyd en area spesifisiteite bevorder word en dus 'n positiewe rol in die aanbod ketting speel. Opportunistiese gedrag binne die bestaande aanbod ketting is neutraal, maar blyk hoog te wees in die vars mark. Transaksie kostes en eienskappe blyk beduidende beperkinge te wees vir kleinskaal mossel produsente om aktief deel te neem in die mark. Die opstel van kontrakte (of vertikale integrasie) blyk dus 'n uitkoms te wees. Respondente het aangetoon dat kontrak boerdery voordelig blyk te wees. Laasgoemde het tot die ontwikkeling van mark kontrakte met die La Vie ('n verwerkings maatskappy) asook produksie bestuur en hulpbron voorsiennings kontrakte met Blue Bay ('n groot kommersiële produsent) gelei. Die kontrakte beperk transaksie koste vir die vars mark en verseker 'n stabiele en betroubare mark vir produsente. 'n Transaksie koste analiese word gebruik om transaksie kostes te ondersoek en te verifieer binne die industrie.

Since the early 1980's there has been a heightened academic interest in the field of commitment, particularly as it relates to business relationships. Knowledge of commitment continues to advance and has begun splintering and applied into specific and narrow fields. The particular field of interest in this study surrounds commitment levels in business relationships within property and casualty insurance distribution networks. The intent of understanding and enhancing commitment levels is to allow stakeholders to explore new ways to improve profitability. This can be achieved by deepening the level of understanding and knowledge of relationship partners with a view to anticipating and fulfilling their needs better than the competition. However, commitment is intangible and involves many factors including human emotion. This increases the difficulty in comprehending the whole phenomenon of commitment. To assist in furthering the knowledge in this area, transaction cost theory is examined and applied to insurance company and broker relationships. In seeking a greater understanding of the underlying drivers of commitment, this thesis investigates the theoretical contribution of transaction cost economics theory in assessing commitment levels. The purpose is to utilize the elements of transaction costs as a means to extend the awareness of how commitment is constructed, and to search for ways to improve and strengthen these relationships. The primary research method consists of three major case studies within the Canadian property and casualty insurance distribution sector. The first case study explores the perspectives of insurance brokers in Ontario. The second study reveals the perceptions of relationship managers employed with ING Canada, the country's largest property and casualty insurance company. Lastly, the research incorporates a series of interviews with ING Canada senior executives to capture their perspectives and validate the research findings from the first two case studies. These investigations into the Canadian insurance industry have provided several outputs, chief among them is the development of a conceptual model referred to as the 'Commitment Wheel'. This model has the advantages of seating affective and calculative commitment at the centre of a moving environment of commitment enablers.

Die Datenerhebung verfolgte das Ziel, Informationen über den Einkauf von EDV-Produkten bei kleinen und mittleren Unternehmen zu gewinnen. Schwerpunktmäßig interessierte uns, wie Unternehmen dem Risiko opportunistischen Verhaltens von Lieferanten in einem so dynamischen Marktbereich wie den EDV-Markt begegnen. Dementsprechend nehmen Fragen über das Management des EDV-Einkaufs, z.B. zur Auswahl von Produkt und Lieferant und der vertraglichen Absicherung der Transaktionen einen wesentlichen Teil des Fragebogens ein. Neben formellen Mechanismen der Absicherung wird jedoch auch die Bedeutung der \"sozialen Einbettung\" von Unternehmen untersucht. Es wurden darum Daten sowohl über die Entwicklung der spezifische Beziehung zwischen beiden Transaktionspartnern als auch deren Beziehungen zu Dritten erhoben. Schließlich beinhaltet der Fragebogen auch eine Reihe von Standardfragen zu den Unternehmen und den befragten Referenzpersonen. Eine Besonderheit dieses Projekts besteht darin, dass wesentliche Teile des Designs der empirischen Studie und insbesondere der verwendete Fragebogen mit einer in den Niederlanden im Jahre 1995 erfolgreich durchgeführten Erhebung weitgehend identisch sind. In der Befragung \"The External Management of Automation 1995” wurden ca. 1000 Interviews mit etwa 800 Firmen über den Einkauf von EDV-Produkten geführt (vgl. Batenburg 1995).

Die vorliegende Studie verfolgt das Ziel, Informationen über den Einkauf von EDV-Produkten bei kleinen und mittleren Unternehmen zu gewinnen. Schwerpunktmäßig interessiert uns, wie Unternehmen dem Risiko opportunistischen Verhaltens von Lieferanten in einem so dynamischen Marktbereich wie dem EDV-Markt begegnen. Das Verhalten von Unternehmen in diesem Marktsegment sollte besonders gut geeignet sein, um Hypothesen über die Lösungsmöglichkeiten von Opportunismusproblemen zu prüfen, wie sie auf Grundlage von transaktionskostentheoretischen, spieltheoretischen sowie netzwerktheoretischen Überlegungen formuliert werden können. Neben der Testung einzelner theoretischer Annahmen erlaubt die Arbeit auch, die Nützlichkeit eines integrativen Vorgehens zu prüfen, bei dem ökonomische und soziologische Ansätze verknüpft werden.
