Failure to collude in the presence of asymmetric information

In this paper, we design the optimal contract when two agents can collude under asymmetric information. They have correlated types, produce complementary inputs and are protected by limited liability. Therefore, a joint manipulation of reports allows them to internalize informational and productive externalities. We show that by taking advantage of the transaction costs created by asymmetric information, even though they collude, the principal can achieve the outcome without collusion regardless of the sign and the degree of correlation. In particular, the principal can implement a non-monotonic quantity schedule in a collusion-proof way while this is impossible if collusion occurs under complete information.

Pitfalls to avoid when measuring institutions: Is "Doing Business" damaging business?

Over recent years, both governments and international aid organizations have been devoting large amounts of resources to simplifying the procedures for setting up and formalizing firms. Many of these actions have focused on reducing the initial costs of setting up the firm, disregarding the more important role of business registers as a source of reliable information for judges, government departments and, above all, other firms. This reliable information is essential for reducing transaction costs in future dealings with all sorts of economic agents, both public and private. The priorities of reform policies should therefore be thoroughly reviewed, stressing the value of the legal institutions rather than trivializing them as is often the case.

Vertical integration or specialisation: producing and commercialising cotton goods (1815-1913)

This article describes the ways in which cotton goods were commercialised during the nineteenth century and the first third of the twentieth. Several national cases are analysed: Britain, as the Workshop of the World; France, Germany, Switzerland and the US, as core economies; and Italy and Spain as countries on the European periphery. The main question that we address is why some cotton industries vertically integrated their production and commercialisation processes, but others did not. We present a model that combines industrial district size and product differentiation to explain why vertical integration was present in most cases and why there was vertical specialisation in Lancashire and Lowell.

Essays in equilibrium asset pricing

Introduction This dissertation consists of three essays in equilibrium asset pricing. The first chapter studies the asset pricing implications of a general equilibrium model in which real investment is reversible at a cost. Firms face higher costs in contracting than in expanding their capital stock and decide to invest when their productive capital is scarce relative to the overall capital of the economy. Positive shocks to the capital of the firm increase the size of the firm and reduce the value of growth options. As a result, the firm is burdened with more unproductive capital and its value lowers with respect to the accumulated capital. The optimal consumption policy alters the optimal allocation of resources and affects firm's value, generating mean-reverting dynamics for the M/B ratios. The model (1) captures convergence of price-to-book ratios -negative for growth stocks and positive for value stocks - (firm migration), (2) generates deviations from the classic CAPM in line with the cross-sectional variation in expected stock returns and (3) generates a non-monotone relationship between Tobin's q and conditional volatility consistent with the empirical evidence. The second chapter proposes a standard portfolio-choice problem with transaction costs and mean reversion in expected returns. In the presence of transactions costs, no matter how small, arbitrage activity does not necessarily render equal all riskless rates of return. When two such rates follow stochastic processes, it is not optimal immediately to arbitrage out any discrepancy that arises between them. The reason is that immediate arbitrage would induce a definite expenditure of transactions costs whereas, without arbitrage intervention, there exists some, perhaps sufficient, probability that these two interest rates will come back together without any costs having been incurred. Hence, one can surmise that at equilibrium the financial market will permit the coexistence of two riskless rates that are not equal to each other. For analogous reasons, randomly fluctuating expected rates of return on risky assets will be allowed to differ even after correction for risk, leading to important violations of the Capital Asset Pricing Model. The combination of randomness in expected rates of return and proportional transactions costs is a serious blow to existing frictionless pricing models. Finally, in the last chapter I propose a two-countries two-goods general equilibrium economy with uncertainty about the fundamentals' growth rates to study the joint behavior of equity volatilities and correlation at the business cycle frequency. I assume that dividend growth rates jump from one state to other, while countries' switches are possibly correlated. The model is solved in closed-form and the analytical expressions for stock prices are reported. When calibrated to the empirical data of United States and United Kingdom, the results show that, given the existing degree of synchronization across these business cycles, the model captures quite well the historical patterns of stock return volatilities. Moreover, I can explain the time behavior of the correlation, but exclusively under the assumption of a global business cycle.

Finnairin lentopetrolihankinnat ja niiden kehittäminen

Tutkimuksen päätavoitteena on ollut Finnair Oyj:n lentopetrolihankintojen tutkiminen ja hankintatoimen kehittäminen. Tutkimuksen pääongelmana on ollut korkea lentopetrolin hinta ja siksi tutkimus on etsinyt ratkaisuja, joiden avulla kustannuspaineita voidaan pienentää. Tutkimus on laadullinen, koska Finnairin lentopetrolihankinnat ovat muutaman henkilön vastuulla ja siten kvantitatiivisen tutkimuksen tekeminen olisi ollut vaikeaa. Empiirinen osuus on tehty henkilökohtaisina haastatteluina joko "face-to-face" -tyyppisenä tai sähköpostitse. Tutkimuksen teoreettisen osuuden sateenvarjona on ollut hankintastrategia, jonka alaisuudessa tutkimuksen muita teorioita ja malleja on käsitelty. Koska hankintastrategian osatekijöiden käyttö ja valinta vaikuttaa ratkaisevasti transaktiokustannusten esiintymiseen, on ollut järkevää katsoa syntyviä kustannuksia hankintastrategisesta näkökulmasta. Elinkaarikustannukset on otettu mukaan tutkimukseen, koska Lisa Ellramin kehittämä Total Cost of Ownership –malli implikoi voimakkaasti ostoprosessin eri vaiheisiin. Tutkimuksen tuloksena voidaan kertoa, että mitään yksiselitteistä ratkaisua korkeaa lentopetrolihintaa vastaan ei ole olemassa. Lentopetrolihankintoja voidaan kehittää, erityisesti hyödyntämällä sähköistä hankintatoimea, jossa prosesseja tehostetaan tietotekniikkaa käyttäen. Lentopetrolihankintoja voidaan tehostaa myös perinteisimmillä menetelmillä, kuten järjestelemällä uudelleen toimintoja ja fyysiseen tankkaustapahtumaan liittyviä keinoja. Hankintastrategian yhteisostot –osatekijä antaa hyvän välineen vipuvaikutuksen käyttämiseen hankinnoissa, taktisen ostamisen ohella. Toimittajasuhteiden syventämisellä ja transaktiokustannusten pienentämisellä voidaan saavuttaa kilpailuetua koko toimitusketjulle. Case –yhtiön tapauksessa tämä tarkoittaa edullisempia lentolippuja loppuasiakkaalle ja kasvavaa kysyntää Finnairille.

Why do municipalities cooperate to provide local public services? An empirical analysis

Intermunicipal cooperation is being increasingly adopted in various countries as a part of local service delivery reforms. This paper draws on survey data from Spain’s municipalities to examine the reasons underpinning the decisions of local governments to engage in intermunicipal cooperation and privatisation. Our empirical analysis indicates that small municipalities prefer to rely on cooperation for reducing costs, while their larger counterparts prefer to privatise the delivery of services. By cooperating, scale economies can be achieved with lower transaction costs and fewer concerns for competition than is the case via private production.

Tämän tutkielman tarkoitus oli tutkia corporate governancen raportointia suomalaisen normiston mukaan. Suositus listayhtiöiden hallinnointi- ja ohjausjärjestelmästä (corporate governance) tuli voimaan vuonna 2004, ja se on tarkoitettu Helsingin Pörssissä listattujen yhtiöiden noudatettavaksi. Listaamattomien yhtiöiden hallinnoinnin kehittämisestä (corporate governance) Keskuskauppakamari julkaisi vuonna 2006 asialuettelon. Laajasti omistetut osuuskunnat Keskuskauppakamari huomioi vuonna 2006 erillisessä kannanotossa, jonka mukaan laajasti omistettujen osuuskuntien tulisi noudattaa nykyistä listayhtiöille annettua suositusta siltä osin, kuin se on mahdollista. Tutkielman teoreettinen viitekehys käsittelee corporate governancen ja sen raportoinnin taustateorioita sekä corporate governancen suomalaista normistoa. Corporate governanen ja sen raportoinnin taustateorioita ovat tässä tutkimuksessa agenttiteoria, stewardship - teoria, stakeholder -teoria, legitimacy -teoria ja transaktiokustannusteoria. Corporate governancen raportointia käytännössä on tutkittu benchmarking-tutkimuksen avulla. Tutkielman empiirisen osan case-tutkimus on tehty Osuuskauppa Hämeenmaassa. Case-tutkimuksen tavoitteena oli löytää kohdeyrityksen corporate governancen raportoinnista kehityskohteita. Tutkimuksen tuloksissa näkyy corporate governancen raportoinnin vapaaehtoisuus sekä osuuskuntamuotoisen yrityksen erityispiirteet.

Efeito do campo magnético na precipitação de parafinas

In the oil industry, the paraffination phenomenon is a major problem during oil production, displacement and treatment. Paraffin deposition in subsea flowlines, surface equipment, production string or even in the reservoir, can cause significant and increasing oil losses. To minimize paraffin precipitation, the application of magnetic field in the petroleum path has been suggested based on empiric studies. In this study, we assembled a labscale magnetic conditioner to determine the influence of magnetic field on the physical-chemical properties of two fluids : oil and a paraffin mixture. We observed that magnetic field reduce sample aparent viscosity due to crystal morphology alteration.

The Pursuit of Efficient Copyright Licensing : How Some Rights Reserved Attempts to Solve the Problems of All Rights Reserved

This dissertation analyses the growing pool of copyrighted works, which are offered to the public using Creative Commons licensing. The study consist of analysis of the novel licensing system, the licensors, and the changes of the "all rights reserved" —paradigm of copyright law. Copyright law reserves all rights to the creator until seventy years have passed since her demise. Many claim that this endangers communal interests. Quite often the creators are willing to release some rights. This, however, is very difficult to do and needs help of specialized lawyers. The study finds that the innovative Creative Commons licensing scheme is well suited for low value - high volume licensing. It helps to reduce transaction costs on several le¬vels. However, CC licensing is not a "silver bullet". Privacy, moral rights, the problems of license interpretation and license compatibility with other open licenses and collecting societies remain unsolved. The study consists of seven chapters. The first chapter introduces the research topic and research questions. The second and third chapters inspect the Creative Commons licensing scheme's technical, economic and legal aspects. The fourth and fifth chapters examine the incentives of the licensors who use open licenses and describe certain open business models. The sixth chapter studies the role of collecting societies and whether two institutions, Creative Commons and collecting societies can coexist. The final chapter summarizes the findings. The dissertation contributes to the existing literature in several ways. There is a wide range of prior research on open source licensing. However, there is an urgent need for an extensive study of the Creative Commons licensing and its actual and potential impact on the creative ecosystem.

Similar problems, different solutions: Comparing refuse collection in the Netherlands and Spain

Local public service provision can vary greatly because of differences in institutional arrangements, public service markets, and national traditions regarding government intervention. In this paper we compare the procedures adopted by the local governments of the Netherlands and Spain in arranging for the provision of solid waste collection. We find that Spain faces a consolidation problem, opting more frequently to implement policies of privatization and cooperation, at the expense of competition. By contrast, the Netherlands has, on average, larger municipalities, resorting somewhat less to privatization and cooperation, and more to competition. The two options - cooperation and competition - have their merits when striving to strike a balance between transaction costs and scale economies. The choices made in organizational reform seem to be related to several factors, among which the nature of the political system and the size of municipalities appear to be relevant.

Choosing hybrid organizations for local services delivery : An empirical analysis of partial privatization

The empirical literature about factors explaining local government delivery choices has traditionally focused the attention on the public or private production dilemma. However, hybrid organizational forms such as mixed public-private firms are increasingly used in several European countries. This paper makes use of survey data from Spanish municipalities to examine motivations of local governments for engaging in hybrid organizational forms. Data refer to two very relevant local services: water distribution and solid waste collection. The empirical analysis indicates that the use of mixed firms emerge as a type of pragmatically based ‘third way’ between pure public and pure private production. Indeed, local governments make use of mixed firms when cost considerations (scale economies, transaction costs and soon), financial constraints and private interests exert contradictory pressures. On the contrary, political and ideological factors do not play any significant role on the local government decision of engaging or not in joint ventures with private partners.

Advanced chemometric methods: Applicability on industrial data

Recent years have produced great advances in the instrumentation technology. The amount of available data has been increasing due to the simplicity, speed and accuracy of current spectroscopic instruments. Most of these data are, however, meaningless without a proper analysis. This has been one of the reasons for the overgrowing success of multivariate handling of such data. Industrial data is commonly not designed data; in other words, there is no exact experimental design, but rather the data have been collected as a routine procedure during an industrial process. This makes certain demands on the multivariate modeling, as the selection of samples and variables can have an enormous effect. Common approaches in the modeling of industrial data are PCA (principal component analysis) and PLS (projection to latent structures or partial least squares) but there are also other methods that should be considered. The more advanced methods include multi block modeling and nonlinear modeling. In this thesis it is shown that the results of data analysis vary according to the modeling approach used, thus making the selection of the modeling approach dependent on the purpose of the model. If the model is intended to provide accurate predictions, the approach should be different than in the case where the purpose of modeling is mostly to obtain information about the variables and the process. For industrial applicability it is essential that the methods are robust and sufficiently simple to apply. In this way the methods and the results can be compared and an approach selected that is suitable for the intended purpose. Differences in data analysis methods are compared with data from different fields of industry in this thesis. In the first two papers, the multi block method is considered for data originating from the oil and fertilizer industries. The results are compared to those from PLS and priority PLS. The third paper considers applicability of multivariate models to process control for a reactive crystallization process. In the fourth paper, nonlinear modeling is examined with a data set from the oil industry. The response has a nonlinear relation to the descriptor matrix, and the results are compared between linear modeling, polynomial PLS and nonlinear modeling using nonlinear score vectors.
